Examples
Referring to fig. 1 to 8, the present embodiment provides a portable printer with a cover opening structure, which includes a deck body 1 and a cover 2 rotatably disposed on the deck body 1.
In the present embodiment, the movement body 1 is provided with a latch member 3 for locking and fixing the upper cover 2 and a cover holder 4 for driving the latch member 3 to switch between a locked state and a cover-opened state. The locking piece 3 is configured on the movement body 1 and can be automatically reset to be in a locking state, and the locking piece 3 is controlled by external force to be switched to a cover opening state. The cover holder 4 is hinge-configured on the deck body 1, and is rotated in a hinge direction by a user's pressing to trigger the latch member 3 to be in a cover-opened state. The upper cover 2 is correspondingly provided with a first triggering part 21 triggering the latch 3 to be in the opened state, the latch 3 is pressed to the latch 3 through the first triggering part 21, so that the latch 3 is switched to the opened state, and after the upper cover 2 is covered to the movement body 1, the latch 3 is reset to the locked state and the first triggering part 21 is fixed relative to the trip so as to limit the upper cover 2 on the movement body 1. The cover opening support 4 rotates under the action of external force to trigger the locking piece 3 to be in a cover opening state, so that the locking piece 3 moves forward to drive the first triggering part 21 arranged on the locking piece to lift up, and after the external force is withdrawn, the locking piece 3 automatically resets to move in the reverse direction, and correspondingly drives the first triggering part 21 to move in the cover opening direction.
In this embodiment, the user presses the cover opening support 4 to rotate along the hinge direction to correspondingly trigger the latch member 3 to be in the cover opening state, and the latch member 3 can be automatically reset to be in the locking state when not receiving external force, so that stable configuration of the upper cover 2 on the movement body 1 is facilitated. Wherein, in the process of closing the cover, the first trigger portion 21 of the upper cover 2 makes the latch member 3 switch to the cover opening state, and after the upper cover 2 is closed on the movement body 1, the latch member 3 resets to the locking state and the first trigger portion 21 is fixed relative to the hook so as to limit the upper cover 2 on the movement body 1, thereby realizing that the upper cover 2 can be simply and conveniently buckled with the movement body 1 by directly pressing the upper cover 2 to lock the upper cover on the movement body 1. Moreover, the cover opening bracket 4 can be rotated along the hinge direction by pressing by a user to trigger the locking piece 3 to be in the cover opening state, at this time, the upper cover 2 is covered on the movement body 1, and then the pressing on the cover opening bracket 4 is correspondingly released, so that the locking piece 3 is automatically reset to the locking state, and the upper cover 2 is limited on the movement body 1. The application adopts various optional covering modes, is beneficial to daily operation and use, improves the printing work efficiency and the like.
When the cover is opened, the cover opening support 4 triggers the locking piece 3 to be in a cover opening state, so that the locking piece 3 moves forward to drive the first triggering part 21 arranged on the locking piece 3 to lift up, and after the external force is withdrawn, the locking piece 3 automatically resets to move in the reverse direction, and correspondingly drives the first triggering part 21 to move in the cover opening direction. Specifically, when the latch 3 is moved forward from the locked state to the unlocked state, the latch 3 drives the first trigger 21 to lift up to a preset height, and the external force is withdrawn to press the door holder 4, so that the latch 3 is automatically reset to move backward from the unlocked state to the locked state when the external force is not applied, and the state of the latch is correspondingly switched. Simultaneously, the reversely moving locking piece 3 drives the first triggering part 21 which is lifted to the preset height to continue to lift and move, so that the first triggering part moves along the direction of opening the cover, and correspondingly drives the upper cover 2 to be opened. In the process of pressing the cover, the locking piece 3 is unlocked and provides an upward lifting force for the upper cover 2, so that the cover opening operation of a user is facilitated, and the upward lifting action is convenient for reminding the user that the cover opening is completed. And, after the user cancels the pressing force, the automatically reset locking piece 3 continues to drive the first trigger part 21 to move along the direction of opening the cover, so that the upper cover 2 is lifted up to be automatically opened under the drive of the locking piece 3.
In one embodiment of the present invention, the first trigger portion 21 includes a printing rubber roller 211 disposed on the upper cover 2, and the printing rubber roller 211 can be disposed opposite to a print head (not shown) in the deck body 1. When the upper cover 2 is cover-fixed to the deck body 1, the printing rubber roller 211 is disposed opposite the print head to form a paper feed path, thereby allowing the label paper to enter to reproduce the print content on the label paper. The locking member 3 has a hook (not shown) for accommodating the groove 31 of the printing roller 211, and a first guiding portion 32 having an inclination angle is disposed along the upper portion of the groove 31. The printing rubber roller 211 is pressed against the first guide part 32 to enter the groove 31, and when the printing rubber roller 211 is separated from the first guide part 32, the locking piece 3 is restored to the locking state so as to limit the printing rubber roller 211 in the groove 31. Correspondingly, a second guiding part 33 is arranged on the other side of the hook along the groove 31 opposite to the first guiding part 32, and the first guiding part 32 and the second guiding part 33 are opposite to each other and form a V-shaped opening. Wherein, a second guiding portion 33 having an inclination is disposed at a side of the groove 31 away from the printing roller 211, and the first guiding portion 32 and the second guiding portion 33 are disposed at left and right sides of the groove 31 respectively, and communicate the groove 31 with an external space. The printing rubber roller 211 presses the first guide part 32 to trigger the locking piece 3 to move along the uncapping state, and when the uncapping support 4 triggers the locking piece 3 to move along the uncapping state, the printing rubber roller 211 accommodated in the groove 31 is lifted upwards to be separated from the groove 31 by the second guide part 33. It should be noted that, the first guiding portion 32 and the second guiding portion 33 generally form a V-shaped entrance, so that the printing rubber roller 211 can enter the groove 31 through the entrance, and when the locking member 3 is in the locking state, the upper cover 2 is pressed to make the printing rubber roller 211 abut against at least part of the first guiding portion 32, so that the locking member 3 is guided to move relatively to the uncapping state, so as to ensure that the printing rubber roller 211 enters the groove 31 through the entrance, and when the printing rubber roller is placed in the groove 31, the locking member 3 is reset to the locking state, one side of the groove 31 and the first guiding portion 32 above are used for limiting the printing rubber roller 211 therein.
Specifically, a base (not shown) of the movement body 1 is provided with a clamping groove 11 corresponding to the locking piece 3, the locking piece 3 is configured to be attached to the base, and the end of the covered printing rubber roller 211 is accommodated in the clamping groove 11, at least part of the clamping hook laterally seals the clamping groove 11, so that the printing rubber roller 211 is accommodated in the clamping groove 11. The locking piece 3 is configured to be attached to the card slot 11 in a lateral manner, and when the locking piece 3 moves along the switching state, the locking piece is correspondingly matched with the card slot 11 to form a clamping space to limit the printing rubber roller 211, or mutually avoid to expose an opening of the card slot 11, and the second guiding portion 33 is allowed to support the printing rubber roller 211 to lift along the opening towards the direction of uncovering.
Specifically, referring to fig. 4 and 5, when the locking member 3 is in the locked state, the first guiding portion 32 of the locking member is at least partially disposed transversely at the opening position of the slot 11, so that the end portion of the printing rubber roller 211 is limited in the clamping space formed by the two by cooperating with the slot 11, which is beneficial to relatively clamping and fixing the end portion of the printing rubber roller 211, and allows the rubber roller body to rotate during printing to cooperate with the printing head. When the cover is required to be unlocked, the cover opening bracket 4 is pressed by the outside to trigger the latch 3 to move along the cover opening state, at this time, the first guide parts 32 of the latch 3 are far away from the clamping grooves 11 to avoid each other, and the second guide parts 33 move forward towards the clamping grooves 11. When the locking piece 3 is in the uncapping state, the second guiding portion 33 is overlapped with the groove wall of one of the clamping grooves 11 and continuously moves forward at least along the switching direction, so that the locking piece 3 is abutted to drive the printing rubber roller 211 to lift up and move through the inclination direction of the second guiding portion 33, and therefore the printing rubber roller 211 accommodated in the groove 31 is ensured to lift up to be separated from the groove 31 through the second guiding portion 33 when the uncapping support 4 triggers the locking piece 3 to move forward along the uncapping state. In particular, the inclination of the second guiding portion 33 is smaller than that of the slot wall of the clamping slot 11, and when the locking member 3 of the second guiding portion 33 is in the uncapping state, the second guiding portion correspondingly abuts against the supporting printing rubber roller 211 to lift the supporting printing rubber roller to a preset height, wherein the preset height is at least higher than the lowest point height of the inclination angle of the first guiding portion 32. When the locking member 3 is automatically reset to the locked state, the printing rubber roller 211 lifted to the preset height continues to lift the printing rubber roller 211 upwards in the reverse direction through the first guide part 32 to be taken out of the clamping groove 11. When the user cancels the pressing of the cover opening support 4, the user moves in the reverse direction through the first guide part 32 by the automatic resetting of the locking piece 3 so as to drive the printing rubber roller 211 positioned at the preset height to continuously lift along the inclination angle guide, thereby realizing the automatic opening of the upper cover 2.
Preferably, the present embodiment includes two locking members 3, and the two locking members 3 are respectively disposed at two sides of the movement body 1, and correspond to two ends of the accommodating clamping printing rubber roller 211. The two sides of the movement body 1 are respectively provided with the locking pieces 3, and the upper cover 2 is respectively and fixedly connected with the two locking pieces 3 through the two ends of the printing rubber roller 211, so that the stress on the two sides is balanced, and the characteristics of stability, balance and the like are realized.
Referring to fig. 4 to 8, the lid bracket 4 includes a rod 41, and a driving portion 42 and a second trigger portion 43 disposed on the rod 41. The rod 41 is arranged approximately perpendicular to the locking piece 3, and is abutted against the locking piece 3 through the second triggering part 43, and the driving part 42 is pressed by a user, so that the rod 41 drives the second triggering part 43 to rotate along the direction facing the locking piece 3, and the locking piece 3 is triggered to be in the uncapped state.
Further, the driving portion 42 is disposed at one end of the rod 41, and the movement body 1 is correspondingly provided with a key hole (not shown), in which a switch key 5 capable of automatically resetting is installed, and the switch key 5 is disposed on the driving portion 42 in a touching manner. By pressing the switch lever 5 by the user, the switch lever 5 abuts against the driving portion 42, thereby driving the driving portion 42 to rotate along the hinge direction of the lever body 41, so that the second triggering portion 43 disposed on the lever body 41 rotates to trigger the latch member 3 to be in the opened state. When the user withdraws the pressing of the switch key 5, the locking piece 3 is automatically reset to the locking state when no external force is applied, and at this time, the locking piece 3 reversely drives the second triggering part 43 to rotate back to the initial position.
The driving portion 42 is crescent, the arc surface of the driving portion faces upwards and contacts with the switch key 5, the parallel surface of the driving portion abuts against the arc-shaped protrusion 6 arranged in the key hole, and the arc surface located above is pressed to drive the driving portion 42 to rotate around the rod 41 and move along the protruding outline. By limiting the driving part 42 between the switch key 5 and the arc-shaped bulge 6, the rotatable threshold value is constant when the switch key 5 is pressed to drive the driving part 42 to rotate, and the conditions of over-deep pressing or difficult pressing are avoided.
Preferably, the second triggering portion 43 has a bar shape and is disposed substantially vertically on the rod 41. The latch 3 extends toward the rotating end face of the second triggering portion 43 to form a bending plate 34, and the bending plate 34 is always abutted against the second triggering portion 43. The second trigger portion 43 always abuts against the bending plate 34, and when the cover holder 4 is not pressed by a user, the latch 3 is reset to the locked state, so as to provide an elastic force abutting against the cover holder 4. And when the cover opening support 4 is pressed by a user, the locking piece 3 always has a tendency of returning to the locking state, so that the second triggering part 43 of the cover opening support 4 is ensured to be always in abutting fit with the bending plate 34 of the locking piece 3.
Referring to fig. 5 to 7, when the latch 3 is reset to the locked state, the cover support 4 returns to the initial position under the abutment of the latch 3 via the second trigger 43. The locking piece 3 is slidably disposed on the movement body 1 along the first direction X, so as to correspondingly switch the state of the locking piece. The rod 41 is arranged along the second direction Y, and the locking piece 3 is provided with a return spring 7, wherein the return spring 7 is arranged along the first direction X and is always in a stretching state so as to drive the locking piece 3 to be abutted against the rod 41. It should be noted that, the sliding fit between the latch 3 and the movement body 1 may be configured by sliding between the bases of the latch 3 and the movement body 1 in the first direction in such a manner that the slide is accommodated in the chute, so as to ensure the switching of the back and forth movement of the latch 3 in two states. The return spring 7 is always in a stretched state, so that the latch 3 is always under the tension of the return spring 7, and moves in the first direction toward the close to the cover holder 4 in a return manner.
In this embodiment, the upper cover 2 is hinged on the movement body 1, and an elastic member 8 is correspondingly disposed near the hinge, where the elastic member 8 provides an elastic force that rotates along the direction of opening the upper cover 2 when the upper cover 2 is opened, so that the upper cover 2 can drive the printing rubber roller 211 to lift to a preset height. The elastic member 8 is configured to provide an elastic force that rotates along the direction of opening the cover when the upper cover 2 is opened, so as to ensure that when the cover support 4 is pressed, the elastic force is increased to directly raise the printing rubber roller 211 to a preset height, thereby avoiding the problem of high required manufacturing precision caused by that the printing rubber roller 211 is driven to be raised to the preset height only by the abutting of the second guide portion 33. Specifically, the elastic member 8 is a protruding elastic member disposed at any one of the inner end surfaces of the upper cover 2 or the movement body 1, and when the two inner end surfaces are covered, the elastic member is enabled to store energy correspondingly, so that when the latch member 3 is in the opened state, the elastic member in the stored energy state releases the elastic member to return to the initial state, and at the same time, provides an elastic force along the direction of opening the upper cover 2.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention.
