Description

A storage box

Technical Field

The invention relates to the field of storage containers, in particular to a storage box.

Background Art

Existing storage boxes include a detachable box body and a box cover, which are usually made of plastic and are often used as containers for accommodating items such as fresh-keeping boxes or storage boxes.

In the prior art, there is a negative pressure fresh-keeping box as shown in the Chinese invention patent with publication number CN110065717A, which includes a box cover and a box body. A support ring is provided on the side of the outer side of the box cover, and a hand-held edge guard is provided on the top surface of the box cover close to the support ring. Pull buckles are rotatably provided on the four sides of the support ring. A hook plate is provided on the outer side of the box body, and a slot is provided on the pull buckle to cooperate with the hook plate. The box cover and the box body are detachably fixed by the cooperation of the pull buckle and the hook plate.

In the above-mentioned related technologies, in order to ensure that the box cover and the box body are firmly connected, buckles are provided on the four sides of the box cover, and corresponding hook plates are provided on the four sides of the box body. When the box cover is connected to the box body, the four buckles need to be pressed one by one to buckle with the four hook plates. When removing the box cover, the buckles also need to be pulled one by one to release the buckle from the hook plates. The operation is relatively laborious and inconvenient to use.

Summary of the invention

In order to solve the defect that the box cover and the box body of the storage box in the prior art are inconvenient to be disassembled and assembled, the present invention provides a storage box, which can realize the rapid buckling and unbuckle of the box cover and the box body, so as to facilitate the use of users.

The above technical objectives of the present invention are achieved through the following technical solutions:

The present invention provides a storage box, comprising a box body and a box cover assembly, wherein the box cover assembly comprises a cover body and an operating ring, wherein the cover body is used to cover the box body, and the operating ring is sleeved outside the cover body; at least two pull buckles are arranged on the edge of the cover body, and a buckling convex portion is arranged on the outer peripheral side of the box body, and the pull buckles can be buckled with the buckling convex portions one by one;

The operating ring portion is connected to a first driving member and a second driving member; the number of the first driving member and the second driving member is the same as the number of the pull buckles, the first driving members are arranged one-to-one on the lower side of the pull buckles, and the second driving members are arranged one-to-one on the upper side of the pull buckles; when the operating ring portion moves upward relative to the cover body, the first driving member drives the pull buckle to flip upward to disengage from the engaging protrusion; when the operating ring portion moves downward relative to the cover body, the second driving member drives the pull buckle to flip downward to engage with the engaging protrusion.

In this solution, the box cover assembly is closed on the upper opening of the box body through the cover body; the operating ring of the box cover assembly can move up and down relative to the cover body, and at the same time, all the pull buttons on the cover body are engaged with the engaging protrusions on the box body, or all the pull buttons are disengaged from the engaging protrusions at the same time. Specifically, when it is necessary to fasten the cover body and the box body, the operating ring moves downward relative to the cover body, and at this time, all the second driving members move downward with the operating ring part and act on the corresponding pull buttons, so that all the pull buttons are synchronously turned downward and engaged with the engaging protrusions on the box body; when it is necessary to separate the cover body and the box body, the operating ring moves upward relative to the cover body, and at this time, the second driving member moves upward with the operating ring part and disengages from the pull button, and the first driving member moves upward with the operating ring part and acts on the pull button, so that the pull button flips upward and disengages from the engaging protrusion. Therefore, the user does not need to pull the pull buttons one by one, and only needs to move the operating ring part up or down to make all the pull buttons engage or disengage with the engaging protrusions, which is convenient for the user to use.

Furthermore, the buckle includes a connecting portion and a buckle, the buckle is fixedly connected to the connecting portion, and the buckle is used to buckle the engaging protrusion; the connecting portion is rotatably connected to the cover body, the first driving member is arranged below the connecting portion and is offset from the buckle, and the first driving member can abut against the side of the connecting portion away from the operating ring portion and push the connecting portion outward.

In the present embodiment, the pull buckle includes a connecting portion and a buckle, the connecting portion is fixedly connected to the buckle; the buckle is used to buckle with the engaging protrusion, and the first driving member and the buckle are staggered so that the first driving member acts on the connecting portion instead of the buckle, so that when the operating ring portion moves upward, the first driving member is inserted into the side of the connecting portion away from the operating ring portion, and the connecting portion is pushed outward, so that the connecting portion and the buckle move outward and flip upward, so that the pull buckle is separated from the engaging protrusion.

Furthermore, a protrusion is provided on a side of the connecting portion facing away from the operating ring portion and/or a side of the first driving member facing the operating ring portion, and when the first driving member is inserted into the side of the connecting portion away from the operating ring portion, the protrusion abuts between the connecting portion and the first driving member.

In the present solution, by arranging a protrusion on the connecting part and/or the first driving member, when the first driving member is inserted into the side of the connecting part away from the operating ring part, the arrangement of the protrusion enables the first driving member to smoothly push the connecting part outward while the thickness of the first driving member will not be too large, thereby making the structure of the first driving member and the connecting part reasonable and reducing consumables.

Further, along the direction in which the first driving member and the connecting portion move away from each other, the protruding height of the protruding portion gradually increases.

In the present embodiment, the height of the protruding portion gradually increases along the direction in which the first driving member and the connecting portion move away from each other, that is, when the protruding portion is arranged on the connecting portion, the height of the protruding portion gradually increases from bottom to top; when the protruding portion is arranged on the first driving member, the height of the protruding portion gradually increases from top to bottom. The protruding portion adopts this arrangement method, which makes it convenient for the protruding portion to abut between the side of the connecting portion away from the operating ring portion and the first driving member when the first driving member moves upward, and to push the connecting portion outward.

Furthermore, the surface of the raised portion is a raised arc surface.

In this solution, the surface of the raised portion is a raised arc surface, so that the surface of the raised portion is smooth and continuous, which facilitates the raised portion to be smoothly squeezed into between the first driving member and the connecting portion.

Furthermore, the protrusion is provided on both the connecting portion and the first driving member, and the protrusion on the connecting portion and the protrusion on the first driving member are arranged to face each other.

In this solution, protrusions are provided on both the connecting portion and the first driving member, and the protrusions on the two are arranged to face each other, so that the connecting portion can be pushed outward a greater distance to ensure that the buckle is separated from the buckling protrusion.

Furthermore, a guide flange is connected to the lower side of the connecting portion, and the guide flange is arranged on a side of the first driving member facing the operating ring portion.

In the present solution, the first driving member is limited by a guide flange on the side of the first driving member facing the operating ring portion to prevent the first driving member from being mistakenly inserted between the connecting portion and the operating ring portion when the operating ring portion moves upward. The guide flange guides the first driving member to ensure that the first driving member moves to the side of the connecting portion away from the operating ring portion to push the connecting portion outward.

Furthermore, a limiting surface is provided on one side of the connecting portion facing the operating ring portion, and when the pull button is flipped upward to disengage from the engaging protrusion, the limiting surface is parallel to and in contact with the inner wall of the operating ring portion.

In the present solution, a limiting surface is provided on one side of the connecting part facing the operating ring part (i.e., the outer side of the connecting part). When the lever is flipped upward to disengage from the snap-fitting protrusion, the limiting surface on the outer side of the connecting part abuts against the inner wall of the operating ring part, so that the inner side of the connecting part abuts against the first driving member and the outer side of the connecting part abuts against the inner wall of the operating ring part. As a result, the operating ring part and the lever are tightly matched, the connecting part is not easy to shake relative to the operating ring part, and the lever and the snap-fitting protrusion are kept in a released state.

Furthermore, the inner periphery of the operating ring is connected to a limiting lip, and the limiting lip surrounds the outside of the cover body; a limiting step is formed at the connection between the connecting portion and the cover body, and the limiting lip can be limitedly matched with the limiting step.

In this solution, the limiting lip surrounds the cover body and can be limited and matched at the limiting step formed by the connecting part and the cover body; at the limiting step, the cover body limits the limiting lip in the radial direction to limit the movement of the operating ring in the radial direction, and the connecting part limits the limiting lip below the limiting lip to limit the downward movement of the operating ring. At the same time, the connecting part limits the first driving member above the first driving member, so that the operating ring is not easy to move upward without applying external force. As a result, when the pull button is fastened with the fastening convex part, the operating ring is not easy to separate from the cover body as a whole, ensuring the stability of the box cover assembly.

Furthermore, the second driving member is fixed to the inner wall of the operating ring portion and extends toward the center of the operating ring portion; when the pull button is engaged with the locking protrusion, the second driving member is blocked between the connecting portion and the inner wall of the operating ring portion; when the pull button is disengaged from the locking protrusion, the pull button flips over and blocks below the second driving member.

In this solution, the second driving member extends toward the center of the operating ring (i.e., inwardly), and when the operating ring moves downward, the second driving member moves downward with the operating ring and presses the connecting part downward to make it flip downward, so that the pull button and the buckle convex part are buckled. At this time, the second driving member is blocked between the connecting part and the inner wall of the operating ring, limiting the connecting part so that the connecting part is not easy to flip outward, and then the pull button will not fall off the buckle convex part without moving the operating ring, thereby ensuring the reliability of the connection between the cover body and the box body.

In summary, the present invention has the following beneficial effects: in this solution, the operating ring moves up and down relative to the cover body, so that all the pull buttons on the cover body are engaged with the engaging protrusions on the box body, or all the pull buttons are disengaged from the engaging protrusions at the same time. When it is necessary to fasten the cover body and the box body, the operating ring moves down relative to the cover body, so that all the pull buttons are synchronously flipped down and engaged with the engaging protrusions on the box body; when it is necessary to separate the cover body and the box body, the operating ring moves up relative to the cover body, so that the pull buttons are flipped up and disengaged from the engaging protrusions. Users do not need to pull the pull buttons one by one, but only need to move the operating ring up or down to engage or disengage all the pull buttons with the engaging protrusions, which is convenient for users to use.

DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the accompanying drawings.

The present embodiment discloses a storage box 1000, referring to Figures 1 and 2, the storage box 1000 comprises a box body 100 and a box cover assembly 200. A storage cavity 110 for placing items is formed in the box body 100, and an opening communicating with the storage cavity 110 is formed above the box body 100. The box cover assembly 200 is detachably connected to the top of the box body 100 to open or close the opening of the box body 100.

The "upper" direction in this embodiment refers to the direction along the opening of the box body 100, and the "lower" direction refers to the direction opposite to the "upper" direction. The "inner" side refers to the side close to the central axis of the box body 100, and the "outer" side refers to the side away from the central axis of the box body 100.

In this embodiment, the box body 100 is in a cubic shape as a whole, and its upper opening is a rectangular opening. Correspondingly, the box cover assembly 200 is in a rectangular shape similar to the upper opening of the box body 100. In addition, in other embodiments, the box cover can also be in other suitable shapes such as cylindrical, truncated cone, other prisms, etc.

The box body 100 can be made of materials such as plastic, stainless steel, aluminum alloy, plastic steel, etc., and can be specifically configured according to the purpose of the storage box 1000. In this embodiment, a plastic box body 100 is specifically selected.

2 , a buckling protrusion 120 is provided on the upper periphery of the box body 100 , and the buckling protrusion 120 is provided along the outer side of the box body 100 and protrudes outward. The buckling protrusion 120 is used for buckling the box cover assembly 200 to connect the box cover assembly 200 to the box body 100 .

1 , the box cover assembly 200 includes a cover body 210 and an operating ring 220 . The cover body 210 is used to cover the box body 100 , and the operating ring 220 is sleeved outside the cover body 210 .

The shape of the cover 210 is similar to the upper side of the box body 100, and the size of the cover 210 is slightly larger than the upper side of the box body 100, so that the cover 210 can cover the box body 100. In this embodiment, the cover 210 is made of plastic. In other embodiments, the cover 210 can also be made of other suitable materials.

3 and 4, a circle of rectangular positioning grooves 211 are provided at the lower side of the cover 210 facing the box body 100, and the upper end of the box body 100 can be inserted into the positioning grooves 211 of the cover 210 to achieve preliminary positioning of the cover 210 and the box body 100. A supporting convex edge 212 is also vertically connected to the lower side of the cover 210, and the supporting convex edge 212 extends continuously to form a shape that matches the upper opening of the box body 100. The supporting convex edge 212 is inserted into the upper opening of the box body 100 and fits with the inner wall of the box body 100, so that the supporting convex edge 212 supports the box body 100 from the inside of the box body 100, enhances the structural strength of the upper part of the box body 100, and prevents the upper part of the box body 100 from being deformed when the box cover assembly 200 is disassembled and assembled on the box body 100.

At least two pull buckles 230 are provided on the edge of the cover body 210, and the pull buckles 230 can be correspondingly engaged with the engaging protrusions 120. The pull buckles 230 are rotatably connected to the cover body 210 so that they can be flipped relative to the cover body 210, so that the pull buckle 230 can be pressed down to engage with the engaging protrusion 120, or flipped upward to disengage the pull buckle 230 from the engaging protrusion 120 to release the engaging state.

In this embodiment, a buckle 230 is provided on each of the four sides of the cover 210, and the four buckles 230 are opposite to each other, so that the four sides of the cover 210 are buckled and connected with the box body 100, and the connection strength is better. In addition, in other embodiments, other numbers of buckles 230 can be provided on each side of the cover 210. For example, in other embodiments, the buckles 230 can be provided only on a set of opposite edges of the cover 210. In other embodiments, when the box body 100 and the cover 210 are of other shapes, the buckles 230 can also be provided in an appropriate manner and in an appropriate number.

The box body 100 is provided with a snap-fitting protrusion 120 at a position corresponding to each pull button 230, so as to snap-fit with each pull button 230 one by one. Specifically, in this embodiment, the snap-fitting protrusion 120 continuously extends along the outer circumference of the box body 100 in a ring shape, so that the pull button 230 in each direction can snap-fit with the snap-fitting protrusion 120. In addition, in other embodiments, the snap-fitting protrusion 120 may also be arranged discontinuously, but only at the portion of the box body 100 corresponding to the pull button 230.

4 and 5 , the pull button 230 includes a connecting portion 231 and a buckle 232. The buckle 232 is fixedly connected to the connecting portion 231. The end of the buckle 232 protrudes toward the box body 100 so that the buckle 232 can be engaged with the engaging protrusion 120. The connecting portion 231 is rotatably connected to the cover body 210 so that the buckle 232 can rotate relative to the cover body 210.

In this embodiment, the connecting portion 231 is made of plastic, and the thickness of the connecting portion 231 at the connection with the box body 100 is less than the thickness of other parts of the connecting portion 231. Since the plastic has a certain flexibility, the connecting portion 231 is easily deformed and bent at the connection with the box body 100, thereby causing the connecting portion 231 and the buckle 232 to rotate up and down relative to the box body 100.

In addition, in other embodiments, the connection portion 231 may also be connected to the box body 100 via a rotatable connection member such as a hinge or a pivot, so as to achieve a rotatable connection between the pull button 230 and the box body 100 .

In this embodiment, the cover 210, the connecting portion 231 and the buckle 232 can be integrally injection molded to reduce the number of mold openings and increase the connection strength between the components. In other embodiments, the cover 210, the connecting portion 231 and the buckle 232 can also be connected after being molded separately.

The operating ring 220 is a rectangular ring-shaped member, and its inner circumference is fitted with the cover 210, that is, the inner circumference of the operating ring 220 is similar to that of the cover 210, and the cover 210 is inserted into the inner circle of the operating ring 220. Of course, in other embodiments, if the cover 210 is circular, the operating ring 220 can also be adapted to be a circular ring member.

The operating ring 220 is sleeved outside the cover 210 and can move up and down relative to the cover 210. Specifically, in this embodiment, the operating ring 220 and the cover 210 are clearance-matched, so that the operating ring 220 can move up and down relative to the cover 210 smoothly.

3 and 6 , the operating ring 220 includes an upper ring 221 and a lower ring 222, wherein the upper ring 221 is fixedly connected to the upper portion of the lower ring 222. The upper ring 221 and the lower ring 222 are both rectangular components extending circumferentially along the outer edge of the cover 210, and the outer circumferential sides of the upper ring 221 and the lower ring 222 are flush.

In this embodiment, the upper ring portion 221 and the lower ring portion 222 are fixed to each other through the annular clamping block and the clamping groove, and the separated upper ring portion 221 and the lower ring portion 222 are easy to be formed separately, reducing the complexity of the mold; the upper ring portion 221 and the lower ring portion 222 can also be detached, so as to install the upper ring portion 221 and the lower ring portion 222 outside the cover body 210. In addition, in other embodiments, the upper ring portion 221 and the lower ring portion 222 can also be integrally manufactured; or, the upper ring portion 221 and the lower ring portion 222 can be fixedly connected by screw connection, threaded matching, bonding or ultrasonic welding.

5 and 6 , the operating ring portion 220 is connected to a first driving member 240 and a second driving member 250, and the number of the first driving member 240 and the second driving member 250 is the same as that of the pull button 230. Specifically, in the present embodiment, four first driving members 240 and four second driving members 250 are respectively arranged on the four rectangular sides of the operating ring portion 220, and the four second driving members 250 are respectively arranged on the four rectangular sides of the operating ring portion 220.

In this embodiment, the first driving members 240 are arranged on the lower side of the pull button 230 in a one-to-one correspondence, and the second driving members 250 are arranged on the upper side of the pull button 230 in a one-to-one correspondence. The first driving members 240 and the second driving members 250 move up or down together with the operating ring 220. When the operating ring 220 moves up relative to the cover 210, the first driving member 240 drives the pull button 230 to flip upward to disengage the engaging protrusion 120; when the operating ring 220 moves down relative to the cover 210, the second driving member 250 drives the pull button 230 to flip downward to engage with the engaging protrusion 120.

Therefore, when the operating ring 220 moves up and down relative to the cover 210, all the pull buttons 230 on the cover 210 can be simultaneously engaged with the engaging protrusions 120 on the box body 100, or all the pull buttons 230 can be simultaneously disengaged from the engaging protrusions 120. The user does not need to pull the pull buttons 230 one by one, but only needs to move the operating ring 220 up or down to engage or disengage all the pull buttons 230 with the engaging protrusions 120, which is convenient for the user.

Specifically, when the cover 210 and the box body 100 need to be fastened, the cover 210 is covered on the box body 100, and the operating ring 220 moves downward relative to the cover 210. At this time, all the second driving members 250 move downward with the operating ring 220 and act on the corresponding pull buckles 230, so that all the pull buckles 230 are synchronously turned downward and engaged with the engaging protrusions 120 on the box body 100. When the cover 210 and the box body 100 need to be separated, the user can press the cover 210 and move the operating ring 220 upward relative to the cover 210. At this time, the second driving member 250 moves upward with the operating ring 220 and disengages from the pull buckle 230, and the first driving member 240 moves upward with the operating ring 220 and acts on the pull buckle 230, so that the pull buckle 230 flips upward and disengages from the engaging protrusion 120.

In this embodiment, the first driving member 240 is disposed below the connecting portion 231 and is offset from the buckle 232, so that the first driving member 240 can abut against the side of the connecting portion 231 away from the operating ring portion 220 and push the connecting portion 231 outward. The first driving member 240 and the buckle 232 are offset so that the first driving member 240 acts on the connecting portion 231 instead of the buckle 232, which facilitates the first driving member 240 to be inserted into the side of the connecting portion 231 away from the operating ring portion 220 when the operating ring portion 220 moves upward, and pushes the connecting portion 231 outward, so that the connecting portion 231 and the buckle 232 move outward and flip upward, so that the pull buckle 230 is separated from the buckling protrusion 120.

4 , in this embodiment, each pull button 230 includes two buckles 232, and the two buckles 232 are spaced below the connecting portion 231, so that a clearance 233 is formed between the two buckles 232 for the first driving member 240 to be inserted, thereby enabling the first driving member 240 to be inserted into the side of the connecting portion 231 away from the operating ring portion 220. In addition, in other embodiments, the buckle 232 and the connecting portion 231 may also be in other suitable forms, as long as the first driving member 240 and the buckle 232 are staggered and the first driving member 240 corresponds to at least part of the connecting portion 231.

5 , a protrusion is provided on the side of the connection part 231 away from the operating ring part 220 and/or the side of the first driving member 240 facing the operating ring part 220, and when the first driving member 240 is inserted into the side of the connection part 231 away from the operating ring part 220, the protrusion abuts between the connection part 231 and the first driving member 240. The provision of the protrusion enables the first driving member 240 to smoothly push the connection part 231 outwards while the thickness of the first driving member 240 is not too large, so that the structure of the first driving member 240 and the connection part 231 is reasonable and less consumables are required.

Specifically, in this embodiment, the protrusion is provided on both the first driving member 240 and the connecting portion 231. The protrusion on the first driving member 240 is defined as the first protrusion 241, and the protrusion on the connecting portion 231 is defined as the second protrusion 234. When the first driving member 240 is inserted into the side of the connecting portion 231 away from the operating ring portion 220 (i.e., the inner side of the connecting portion 231), the first protrusion 241 and the second protrusion 234 face and abut against each other, so that the connecting portion 231 can be pushed outward for a greater distance, ensuring that the buckle 232 can be separated from the buckling protrusion 120.

In which, along the direction in which the first driving member 240 and the connecting portion 231 move away from each other, the protruding height of the protruding portion gradually increases. That is, the height of the first protruding portion 241 provided on the first driving member 240 gradually increases from top to bottom (i.e., the distance protruding from the surface of the first driving member 240); the height of the second protruding portion 234 provided on the connecting portion 231 gradually increases from bottom to top (i.e., the distance protruding from the surface of the connecting portion 231). The first protruding portion 241 and the second protruding portion 234 are gradually increased in height, so that when the first driving member 240 moves upward, the first protruding portion 241 slides to the surface of the second protruding portion 234 and abuts against each other, thereby pushing the connecting portion 231 outward.

In this embodiment, the surfaces of the first protrusion 241 and the second protrusion 234 are both convex arc surfaces, so that the surfaces of the first protrusion 241 and the second protrusion 234 are smooth and continuous, so that the first protrusion 241 can slide relative to the second protrusion 234 and abut against the second protrusion 234 more smoothly and stably. In addition, in other embodiments, the surfaces of the first protrusion 241 and the second protrusion 234 can also be inclined surfaces, and when the first protrusion 241 and the second protrusion 234 contact, the two inclined surfaces abut against each other, and as the first protrusion 241 moves upward, the second protrusion 234 is pressed outward.

4 and 5 , in this embodiment, a guide flange 235 is connected to the lower side of the connecting portion 231, and the guide flange 235 is arranged on the side of the first driving member 240 facing the operating ring portion 220. The lower edge of the guide flange 235 is always located below the upper edge of the first driving member 240. The guide flange 235 is arranged in the avoidance gap between the two buckles 232, and the first driving member 240 is limited by the guide flange 235 on the side of the first driving member 240 facing the operating ring portion 220, so as to avoid the first driving member 240 from being inserted into the connecting portion 231 and the operating ring portion 220 by mistake when the operating ring portion 220 moves upward. The guide flange 235 guides the first driving member 240, and ensures that the first driving member 240 moves to the side of the connecting portion 231 away from the operating ring portion 220 to push the connecting portion 231 outward.

5 to 8, a limiting surface 236 is provided on one side of the connection portion 231 facing the operating ring portion 220 (i.e., the outer side of the connection portion 231), and the limiting surface 236 is a flat straight surface. When the pull button 230 is flipped upward to disengage the buckling protrusion 120, the limiting surface 236 is parallel to the inner wall of the operating ring portion 220, so that the inner side of the connection portion 231 abuts against the first driving member 240, and the outer side of the connection portion 231 abuts against the inner wall of the operating ring portion 220, thereby the operating ring portion 220 and the pull button 230 are closely matched, and the connection portion 231 is not easy to shake relative to the operating ring portion 220, so that the pull button 230 and the buckling protrusion 120 are kept in a state of being released from buckling.

The inner periphery of the operating ring 220 is connected to a limiting lip 260, which is disposed above the operating ring 220 and surrounds the outside of the cover 210. In this embodiment, the limiting lip 260 continuously extends along the outer periphery of the cover 210 to form a continuous rectangular ring structure, so that the operating ring 220 is limited in the radial direction of the cover 210 by the cooperation between the cover 210 and the limiting lip 260, so that the operating ring 220 is not easy to shake relative to the cover 210 in a direction perpendicular to the up and down direction.

A limiting step 270 is formed at the connection between the connection part 231 and the cover body 210, and the limiting step 270 protrudes in the direction away from the cover body 210. When the operating ring part 220 moves downward, the limiting lip 260 can be limited and matched with the limiting step 270. At the limiting step 270, the cover body 210 limits the limiting lip 260 in the radial direction to limit the movement of the operating ring part 220 in the radial direction. The connection part 231 limits the limiting lip 260 below the limiting lip 260 to limit the downward movement of the operating ring part 220. At the same time, the connection part 231 limits the first driving member 240 above the first driving member 240, so that the operating ring part 220 is not easy to move upward without applying external force. As a result, when the pull button 230 is fastened with the fastening protrusion 120, the operating ring part 220 as a whole is not easy to separate from the cover body 210, ensuring the stability of the box cover assembly 200.

5 and 6, in this embodiment, an upper support ring 280 is extended inwardly from the upper end of the upper ring portion 221, and the inner end of the upper support ring 280 is fixedly connected to the limiting lip 260. A lower support ring 290 is extended inwardly from the lower end of the lower ring portion 222, and the inner end of the lower support ring 290 is connected to the first driving member 240. Thus, by setting the upper support ring 280 and the lower support ring 290, a space for the flipping of the trigger 230 is formed on the side of the operating ring portion 220 facing the cover body 210, so as to avoid interference between the operating ring portion 220 and the trigger 230.

In this embodiment, the first driving member 240 and the second driving member 250 are both arranged vertically. Specifically, the first driving member 240 extends upward perpendicularly to the lower supporting ring portion, the second driving member 250 is fixed to the inner wall of the upper ring portion 221 and extends toward the center of the operating ring portion 220, the second driving member 250 is located above the trigger 230 and outside the trigger 230, and when the trigger 230 flips upward to disengage the engaging protrusion 120, the trigger 230 is located on the downward movement path of the second driving member 250.

5, when the operating ring 220 moves downward, the second driving member 250 moves downward with the operating ring 220 and presses the connecting portion 231 downward to make it flip downward, so that the pull button 230 is engaged with the locking protrusion 120. At this time, the second driving member 250 is blocked between the connecting portion 231 and the inner wall of the operating ring 220. At this time, the second driving member 250 limits the connecting portion 231, so that the connecting portion 231 is not easy to flip outward, and then the pull button 230 will not be separated from the locking protrusion 120 without moving the operating ring 220, thereby ensuring the reliability of the connection between the cover 210 and the box body 100.

8 , when the operating ring 220 moves upward, the second driving member 250 moves upward with the operating ring 220 to leave the connecting portion 231. At this time, the connecting portion 231 can be flipped upward under the action of the first driving member 240, so that the pull button 230 is separated from the engaging protrusion 120. At this time, the pull button 230 is flipped and blocked below the second driving member 250.

In this embodiment, a side surface of the second driving member 250 facing away from the operating ring portion 220 is a vertical plane, so as to better fit the side of the limiting connection portion 231 facing the operating ring portion 220 after the second driving member 250 moves downward.

The operating principle of a storage box 1000 of this embodiment is:

5 , when the cover 210 is required to be buckled with the box body 100, the cover 210 is covered on the box body 100, and the cover 210 is supported by the box body 100. The user presses down the operating ring 220 by hand, so that the operating ring 220 moves downward relative to the cover 210. At this time, the operating ring 220 drives the four first driving members 240 to move downward, and the four second driving members 250 move downward and press down the four pull buttons 230, so that the four pull buttons 230 turn downward and buckle the buckling protrusions 120 on the box body 100 at the same time. The second driving member 250 is blocked between the connecting portion 231 of the pull buckle 230 and the inner wall of the operating ring portion 220 to prevent the pull buckle 230 from opening automatically; the limiting lip 260 is limited above the cover body 210, and the first driving member 240 is limited below the pull buckle 230. At the same time, the limiting lip 260 limits the operating ring portion 220 in the radial direction, thereby making the operating ring portion 220 stably arranged outside the cover body 210 and not prone to shaking, which is convenient for users to use.

Referring to Figure 8, when it is necessary to separate the cover body 210 and the box body 100, the user presses the cover body 210 to prevent the cover body 210 from moving, and then pulls up the operating ring 220 to move the operating ring 220 upward, and the four second driving members 250 move up to leave the buckles 230, and the four first driving members 240 move up and insert the connecting parts 231 of the four buckles 230 away from the side of the operating ring 220, and the first protrusions 241 and the second protrusions 234 abut against each other to push the four buckles 230 outward, so that the buckles 230 flip upward to disengage from the locking protrusions 120, and at this time, the cover body 210 can be removed from the box body 100 by moving the cover body 210 upward.

The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
