Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and embodiment:

Embodiment 1: As shown in Figures 1 to 8, a portable collapsible material box includes a box body 1, which is a hollow structure with an open top, and the box body 1 includes a bottom plate 2 and two sets of lateral sides. Plate 3 and two sets of longitudinal side plates 4, the lateral side plates 3 on both sides are relatively arranged on the top of the left and right sides of the bottom plate 2, and two sets of longitudinal side plates 4 are relatively arranged on the front and rear sides of the bottom plate 2 At the top, the bottoms of the transverse side plates 3 and the longitudinal side plates 4 are all hingedly mounted on the top surface of the bottom plate 2, and two groups of the longitudinal side plates 4 are arranged between two groups of transverse side plates 3, each group The inner wall at both ends of the transverse side plate 3 is provided with a baffle plate 5, and each group of the baffle plate 5 is provided with a plurality of bayonet sockets 6, corresponding to the outer walls at both ends of the longitudinal side plate 4 of each group. 7, each of the protrusions 7 is correspondingly locked in each of the bayonet sockets 6, and each group of the longitudinal side panels 4 is connected to the lateral side panels 3 on both sides through a connecting mechanism; The snap-in mechanism is arranged above the inside of the longitudinal side plate 4, the snap-in mechanism includes a handle 8 and elastic top blocks 9 arranged at both ends of the handle, and the two ends of the handle 8 are against the elastic top block 9 , the inside of the elastic top block 9 is against the end of the handle 8, and the outside of the elastic top block 9 is exposed outside the longitudinal side plate 4, corresponding to both sides of the inner wall of the transverse side plate 3 A limit block 10 is provided respectively, and a gap 11 is provided between the limit block 10 and the corresponding baffle plate 5 , and the outer end of the elastic top block 9 abuts against the gap 11 .

In the unfolded state of the box body, the transverse side panels and the longitudinal side panels are arranged perpendicular to the bottom panel, and the outer walls of the two ends of the longitudinal side panels are against the baffles at the ends of the two groups of the transverse side panels. Through the limitation of the protrusion and bayonet and the limitation of the clamping mechanism; when the box is folded, the longitudinal side panels are attached to the bottom plate, and the lateral side panels are attached to the two sets of lateral sides board.

In this embodiment, the box body is made of plastic, the handle is a U-shaped structure, the two ends of the handle are provided with extension plates, and the end of the extension plate is against the inner end surface of the elastic top block, so the handle is also made of plastic , will have a certain degree of elasticity. Among them, under normal use conditions, that is, in the folded state of the box body, the bottoms of the horizontal side panels and the longitudinal side panels are attached to the top surface of the bottom panel, and the bottom surfaces of the horizontal side panels and the longitudinal side panels It is arranged parallel to the top surface of the bottom plate. In the folded state, the outer surfaces of the lateral side panels and the longitudinal side panels (that is, the bottom surface in the use state) are arranged perpendicular to the bottom plate. The bottom of the bottom plate is attached to the top surface of the bottom plate, so that it cannot continue to be turned outwards to ensure the quality of use. At the same time, the protrusions and bayonets are used to limit the lateral and longitudinal side plates, so that the four sides of the box body All can be connected with each other and limit each other to ensure quality. Among them, a gripping groove is provided in the middle of the transverse side plate and the longitudinal side plate to facilitate the lifting of the box body, which is convenient for transshipment after the box body is loaded with products. Wherein the handle is arranged at the edge of the grasping groove, which not only facilitates the operation of the handle, but also reduces the occupation of space and reduces the cost.

In this embodiment, pulling the handle up makes the handle elastically move up and slightly deform, and the end of the handle breaks away from the inner end surface of the elastic top block, releasing the limit of the handle to the elastic top block, The elastic top block is elastically shrunk toward the inside of the longitudinal side plate, so that the elastic top block can break away from the limit of the limit block, and the longitudinal side plate can be folded and attached to the top surface of the bottom plate.

In this embodiment, the box body is in the folded state first, so that the box body only has the thickness of the bottom plate plus the thickness of the transverse side plate plus the thickness of the longitudinal side plate, its volume is particularly small, and the space occupation is particularly small, which is convenient for no-load The transportation and storage in the state can effectively reduce the cost. When in use, first unfold the lateral side panels on both sides so that the lateral side panels are perpendicular to the bottom panel, and then turn the longitudinal side panels outward so that the longitudinal side panels are perpendicular to the bottom panel. The outside of both sides of the plate will be against the baffle at the end of the transverse side plate, and the baffle will be used to block the longitudinal side plate to prevent the longitudinal side plate from turning over excessively, so that the protrusions of the longitudinal side plate will be snapped into the clips of the corresponding baffle Inside the mouth, a connection relationship will be formed between the longitudinal side panels and the transverse side panels, which can ensure the stability of the longitudinal side panels and the transverse side panels after they are turned over, and ensure the firmness of the box body. At the same time, during the outward turning process of the longitudinal side plates, the elastic top blocks on both sides first touch the limit blocks on the corresponding lateral side plates, and the elastic top blocks will be squeezed due to the force of the longitudinal side plates being turned outwards. Make the elastic top block withstand the end of the handle, extrude and deform, make the elastic deformation shrink to the inside of the longitudinal side plate, then the elastic top block passes through the limit block, and then snaps into the gap, and the elastic top block returns to its original shape, so that The longitudinal side plate and the transverse side plate are limited by the elastic top block and the gap, so that the protrusion of the longitudinal side plate can be prevented from detaching from the bayonet, forming a position limit, and further ensuring the firmness of the box body. After use, when the box body does not need to be loaded with products, the box body needs to be folded, so that the operator pulls the handle to elastically deform the handle, and the end of the handle is separated from the inner end surface of the elastic top block. Release the limit of the elastic top block by the handle, and then the operator pushes the longitudinal side plate inward. Since the limit of the elastic top block by the handle disappears, the elastic top block elastically shrinks to the inside of the longitudinal side plate, so that all The elastic top block can break away from the limit of the limit block, and the longitudinal side plate can be folded and pasted on the top surface of the bottom plate. Then turn the two horizontal side panels inward, so that the horizontal side panels are attached to the longitudinal side panels to complete the folding of the box, which can greatly reduce the space occupied, facilitate the storage of the box itself, and facilitate When empty, the space occupied can be reduced, and the remaining space can be used to transport other products that do not need to be loaded in a box, which can effectively improve the utilization rate of transportation and reduce transportation costs.

Referring to Figures 2 to 7, the two ends of the handle 8 are respectively provided with a first inclined guide surface 12, and the first inclined guide surface 12 is inclined downward from the outside to the inside, and the first inclined guide surface 12 The top is arranged in the middle of the end surface of the handle 8, the bottom of the first inclined guide surface 12 is arranged on the bottom surface of the handle 8; the inner end of the elastic top block 9 is provided with a second inclined guide surface 13, so The second inclined guide surface 13 is arranged parallel to the first inclined guide surface 12, the bottom of the second inclined guide surface 13 is arranged in the middle of the inner end of the elastic top block 9, and the second inclined guide surface 13 The top is arranged on the top surface of the elastic top block 9 , and the first inclined guiding surface and the second inclined guiding surface are arranged in the same plane.

The top surface of the limiting block 10 is a third inclined guiding surface 14, and the third inclined guiding surface is inclined downward from the outside to the inside, and the bottom of the third inclined guiding surface and the bottom of the inner end of the limiting block Arranged flush, the top of the third inclined guide surface is arranged flush with the top of the outer end of the limiting block, and the bottom surface of the elastic top block is arranged flush with the bottom surface of the limiting block.

In this embodiment, during the opening process of the longitudinal side plate, when the elastic top block first touches the limit block, the elastic top block will first touch the third inclined guide surface, because the longitudinal side plate turns outward , by the outward pulling force, in the process of turning the longitudinal side plates outward, the elastic top block gradually tilts and deforms, making it touch and move upward on the third inclined guide surface. When the elastic positioning completely passes through the limit block, the elastic top block The top block is restored, so that the bottom of the elastic top block is flush with the bottom of the limit block, and the elastic top block completely falls into the gap, and the limit block is used to restrict the longitudinal side panels from turning inward, and the baffle plate is used to restrict the longitudinal side panels from outward Flip over to complete the limit.

When the longitudinal side panels need to be folded, pull up the handle, and the end of the handle, that is, the end of the extension plate, moves up some distance, so that the first inclined guide surface moves upward, and the elastic top block recovers to shrink inwardly, so that the second The second inclined guide surface is pasted on the first inclined guide surface, and then the operator uses a little force to push the longitudinal side plate to turn inward, so as to squeeze the elastic top block, so that the elastic top block is shrunk inward by the thrust of the limit plate until The elastic top block breaks away from the limit plate. Wherein, in the process of opening the longitudinal side plate, due to the elastic positioning, it will first touch the third inclined guide surface, and at the same time, due to the existence of the third inclined guide surface, it will drive the outer side of the elastic top block to rise and the inner side to fall, so that due to the elasticity The decline of the inner side of the jacking block will cause the second inclined guide surface to descend and contact the first inclined guiding surface, which facilitates the deformation of the elastic jacking block and facilitates the elastic jacking block to enter the gap through the limit block. After the elastic jacking block completely enters the gap, the elastic jacking block lacks the upward thrust of the third inclined guide surface, and the elastic jacking piece returns to its original shape, so that the second inclined guide surface is separated from the first inclined guide surface, so that the end of the handle rests on the The inner end of the elastic top block, so that even if the longitudinal side plate is pushed inward, the elastic top block cannot be deformed, because it is resisted by the end of the handle, and the handle must be lifted to make the end of the handle separate from the elastic top block. end, the elastic top block can break away from the limit block.
