Description
Technical Field
[0001] This utility model relates to the field of box assembly technology, specifically to a box interlocking structure. Background Technology
[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.
[0003] To improve space utilization, a modular box that can be stacked on top of each other has emerged. The two boxes are combined and spliced by a snap-fit method using blocks and slots. However, when unlocking the two boxes, there are various ways to separate the blocks and slots. The common method in the existing technology is to manually separate the blocks and slots one by one. Since there are usually multiple pairs of blocks and slots and they are located on at least two sides of the box, this method is not convenient to use.
[0004] Furthermore, some of the locking blocks have a torsion spring design, which will automatically lock into the slot when the upper and lower boxes are not separated. For this type of structure design, another person is required to manually keep the locking block and the slot unlocked, which wastes manpower.
[0005] Therefore, this application proposes a convenient interlocking structure that prevents the card block from automatically getting stuck in the card slot in the unlocked state. Utility Model Content
[0006] To address the shortcomings mentioned in the background section, this utility model provides a box interlocking structure.
[0007] To achieve the above objectives, the technical solution of this utility model is as follows: a box interlocking structure is provided on the upper box of two boxes, the upper box has a slot, and the lower box has a locking block that cooperates with the slot.
[0008] The interlocking structure of the housing includes a mounting groove, which is located on one side of the housing and communicates with each slot on the side of the housing. A pushing block is slidably disposed at the position where the mounting groove communicates with each slot. One side of the pushing block extends into the mounting groove and has an inclined surface. A movable rod is disposed in the mounting groove. A wedge block is disposed at the position of the movable rod corresponding to the pushing block. Moving the movable rod can drive the wedge block to abut against the inclined surface on the pushing block, causing the pushing block to move into the slot and push the slot block out of the slot.
[0009] It also includes a locking component for locking the position of the movable lever after the card block exits the card slot.
[0010] Furthermore, the locking assembly includes a limiting block slidably disposed on the movable rod, the limiting block moving together with the movable rod, and a clearance groove at the bottom of the housing corresponding to the position of the limiting block, the clearance groove communicating with the mounting groove, and a first elastic element disposed between the limiting block and the movable rod, the first elastic element being used to push one end of the limiting block downward, so that one end of the limiting block passes downward through the clearance groove and contacts the housing below;
[0011] It also includes a limiting stop bar located on the top of the lower housing, the limiting stop bar being used to prevent the limiting block from moving together with the movable rod that moves during reset;
[0012] It also includes a reset block disposed in the mounting slot, which is used to push the limit block to move upward and reset when the upper and lower housings are separated and the movable rod is reset.
[0013] Furthermore, the reset block is an inclined block disposed in the mounting groove, and the inclined block is located at the clearance groove; the limiting block is provided with a contact part on one side of the corresponding inclined block, and the contact part slides in contact with the inclined surface on the inclined block, which is used to abut against the inclined surface on the inclined block when the movable rod is reset, forcing the limiting block to move upward.
[0014] Furthermore, it also includes a third elastic element, which is used to push the push block to move away from the slot.
[0015] Furthermore, one end of the movable rod extends out of one side of the housing and is provided with a pushing part. Operating the pushing part can push the movable rod to move in the mounting groove. A movable groove is opened on one side of the corresponding pushing block of the movable rod. The wedge block is detachably installed in the movable groove. The side of the pushing block with the inclined surface extends into the movable groove and slides in cooperation with the upper and lower sides of the groove opening. The pushing block can move relative to the movable groove along the movement direction of the movable rod.
[0016] Furthermore, after the movable rod is reset, the side wall of the movable groove in the direction of movement contacts one side of the push block.
[0017] Furthermore, the pushing part is a pull-out wrench, the top of which is located on the side of the housing for the finger to pull outwards, the middle of which is rotatably disposed in the mounting groove, and the bottom of which slides in contact with the end of the movable rod to push the movable rod to one side.
[0018] Furthermore, the pushing part also includes an L-shaped fixing block, which is located at one end of the movable rod corresponding to the pulling wrench. The short side of the L-shaped fixing block is fixedly connected to the movable rod. The bottom of the pulling wrench has a sliding groove, and the long side of the L-shaped fixing block passes through the sliding groove. When the pulling wrench moves back and forth, the long side of the L-shaped fixing block will not come out of the sliding groove. This ensures that after the pulling wrench is pulled outward, it remains in the open state and does not reset before the upper box is lifted, providing the user with unlocking status information.
[0019] Furthermore, the box interlocking structure also includes a detachable housing portion installed at the bottom of the box, the mounting groove is disposed within the housing portion, and the pushing block is slidably disposed within the housing portion, so that the box interlocking structure as a whole forms an independently detachable and assembleable combined component.
[0020] Furthermore, a slot is provided on one side of the corresponding housing part at the bottom of the box.
[0021] The beneficial effects of this utility model are reflected in:
[0022] This invention unlocks the upper and lower housings by moving a movable rod along with its wedge-shaped block, causing a pushing block to move into a slot until the locking block is ejected from the slot. The locking component prevents the locking block from automatically locking in the slot when unlocked. This solution allows for single-person operation and requires only one operation to unlock both housings, making it convenient to use. Attached Figure Description

Detailed Implementation
[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.
[0033] See Figures 1 to 6 .
[0034] This utility model discloses a box interlocking structure, which is set on the upper box of two boxes, the upper box has a slot 1, and the lower box has a block 2 that cooperates with the slot 1.
[0035] The interlocking structure of the box includes a mounting groove 31, which is located on one side of the box and communicates with each slot 1 on the side of the box. A push block 4 is slidably arranged at the position where the mounting groove 31 communicates with each slot 1. One side of the push block 4 extends into the mounting groove 31 and has an inclined surface. A movable rod 5 is arranged in the mounting groove 31. A wedge block 51 is arranged at the position of the movable rod 5 corresponding to the push block 4. Moving the movable rod 5 can drive the wedge block 51 to abut against the inclined surface on the push block 4, so that the push block 4 moves into the slot 1 until the slot 2 located in the slot 1 is pushed out of the slot 1.
[0036] It also includes a locking component 6, which is used to lock the position of the movable lever 5 after the card block 2 exits the card slot 1.
[0037] In specific implementation, there are many locking components 6 that can lock the position of the movable rod 5. For example, there is an automatic telescopic locking mechanism installed in an automatic cylindrical pen. By setting the spring in the automatic telescopic locking mechanism at one end of the moving direction of the movable rod 5 and setting the rest of the automatic telescopic locking mechanism at the other end, the movable rod 5 is manually pushed to one side. After the movable rod 5 moves into place, the position of the movable rod 5 is automatically locked. Pushing the movable rod 5 again will automatically reset the movable rod 5. Of course, the most commonly used top ball limiting structure in the existing technology can also be used. A limiting hole is opened in the housing, and the top ball and spring are set on the movable rod 5. After the movable rod 5 moves into place, the spring pushes the top ball into the limiting hole to limit the movable rod 5. When unlocking the movable rod 5, pressing the top ball out of the limiting hole will release the limitation of the movable rod 5.
[0038] In this application, during operation, the movable lever 5 is manually pushed, causing it and the wedge block 51 on it to move together. This moves the pushing block 4 into the slot 1 until the locking block 2 located in the slot 1 is pushed out, thus unlocking the upper and lower boxes. The locking component 6 prevents the movable lever 5 from shifting, preventing the pushing block 4 from retracting and preventing the locking block 2 from re-entering the slot 1. This application allows for single-person operation during unlocking, and both boxes can be unlocked in a single operation, making it convenient to use.
[0039] Preferably, the locking block 2 is rotatably mounted on the lower housing, and a torsion spring (not shown in the figure) is provided between the rotating shaft of the locking block 2 and the housing. Driven by the torsion spring, the locking block 2 moves to the side of the locking groove 1 and engages with the locking groove 1.
[0040] In one embodiment, the locking assembly 6 includes a limiting block 61 vertically slidably disposed on the movable rod 5. The limiting block 61 moves together with the movable rod 5. The bottom of the housing has a relief groove 7 at the position corresponding to the limiting block 61. The relief groove 7 communicates with the mounting groove 31. A first elastic member 62 is disposed between the limiting block 61 and the movable rod 5. The first elastic member 62 is used to push one end of the limiting block 61 downward when the movable rod 5 moves and drives the wedge block 51 to abut against the inclined surface on the pushing block 4 and pushes the locking block 2 in the locking groove 1 out of the locking groove 1, so that one end of the limiting block 61 passes downward through the relief groove 7 and contacts the housing below.
[0041] It also includes a limiting stop 8 located on the top of the lower housing, which is used to prevent the limiting block 61 from moving together with the movable rod 5 that moves during reset.
[0042] It also includes a reset block 32 disposed in the mounting groove 31. The reset block 32 is used to push the limit block 61 to move upward and reset when the upper and lower housings are separated and the movable rod 5 is reset.
[0043] In practice, the limiting block 61 moves together with the movable rod 5. After the locking block 2 exits the locking slot 1 and the movable rod 5 moves into place, the limiting block 61 is released from its constraint with the reset block 32. Under the push of the first elastic element 62, it extends towards the limiting stop 8 on the lower box and cooperates with the limiting stop 8 to prevent the limiting block 61 from moving back to its original position. After the upper and lower boxes are separated, the limiting block 61 and the limiting stop 8 automatically release their limiting relationship. At this time, when the movable rod 5 moves back to its original position, the limiting block 61 will move upward and reset under the push of the reset block 32, which facilitates the recombination of the upper and lower boxes.
[0044] Preferably, the limiting stop 8 is the groove wall of the recess at the top of the lower housing.
[0045] Preferably, the top of the lower box body has a raised surface, and the side of the raised surface also serves as a limiting strip 8. This design utilizes the shape of the top cover surface of the box body, where the raised surface (i.e., the large raised surface) is both the main support surface and the edge also serves as a limiting element.
[0046] In one embodiment, a second elastic element 33 is provided in the mounting groove 31, which is used to push the movable rod 5 to reset. With this design, although the movable rod 5 can be reset manually even without the second elastic element 33, the addition of the second elastic element 33 further improves the convenience for the user.
[0047] In one embodiment, the reset block 32 is an inclined block disposed in the mounting groove 31, and the inclined block is located at the clearance groove 7; the limiting block 61 is provided with a contact portion 611 on one side of the corresponding inclined block, and the contact portion 611 slides in contact with the inclined surface on the inclined block, and is used to abut against the inclined surface on the inclined block when the movable rod 5 is reset, forcing the limiting block 61 to move upward.
[0048] In one embodiment, a third elastic element 34 is also included, which is used to push the push block 4 to move away from the slot 1. This design can prevent the card block 2 from failing to engage with the slot 1 due to the obstruction of the push block 4 when the upper and lower boxes are stacked together (because the card block 2 moves in an arc, while the push block 4 moves in a straight line, the push block 4 can easily push the card block 2 out of the slot 1, while the card block 2 cannot easily move the push block 4 in the opposite direction).
[0049] Preferably, the third elastic member 34 can be disposed between the push block 4 and the housing, between the push block 4 and the mounting groove 31, or between the housing part 3 and the push block 4 mentioned later, etc., without limiting its specific position.
[0050] Preferably, the first elastic element 62, the second elastic element 33 and the third elastic element 34 can all be springs.
[0051] In one embodiment, the movable rod 5 is a rod with a non-circular end cross-section. One end of the movable rod 5 extends out of one side of the housing and is provided with a pushing part 9. Operating the pushing part 9 can push the movable rod 5 to move within the mounting groove 31. A movable groove 52 is provided on one side of the corresponding pushing block 4 of the movable rod 5. The wedge block 51 is detachably installed in the movable groove 52. The side of the pushing block 4 with an inclined surface extends into the movable groove 52 and slides in cooperation with the upper and lower sides of the groove opening of the movable groove 52. The pushing block 4 can move relative to the movable groove 52 along the movement direction of the movable rod 5.
[0052] In practice, the detachable design of the wedge block 51 allows it to be replaced when it experiences significant wear. By allowing one side of the push block 4 to extend into the movable groove 52, it facilitates assembly and positioning, and also prevents the push block 4 from tilting upwards or downwards under external force. At the same time, the movable rod 5 has a simpler appearance, with all components located inside the rod, making it convenient to sell the movable rod 5 as a separate component.
[0053] Preferably, the pushing part 9 is a block fixed to the end of the movable rod 5 for pressing by a finger.
[0054] In one embodiment, after the movable rod 5 is reset, the sidewall of the movable groove 52 in the direction of movement contacts one side of the push block 4. This design can prevent the movable rod 5 from moving too much when it is reset; and with this structure, there is no need to set up a separate structure to limit the displacement distance of the movable rod 5, which reduces the structural complexity and reduces production and manufacturing costs to a certain extent.
[0055] In one embodiment, to facilitate the user's pushing of the movable lever 5, the pushing part 9 is a pull-out wrench 91. The top of the pull-out wrench 91 is located on the side of the housing, allowing the finger to pull outwards. The middle part of the pull-out wrench 91 is rotatably disposed in the mounting groove 31, and the bottom of the pull-out wrench 91 slides in contact with the end of the movable lever 5, for pushing the movable lever 5 to one side. This design reduces the difficulty of pushing the movable lever 5 and makes it convenient for the user.
[0056] In one embodiment, the pushing part 9 further includes an L-shaped fixing block 92 located at one end of the movable rod 5 corresponding to the pulling wrench 91. The short side of the L-shaped fixing block 92 is fixedly connected to the movable rod 5. A groove is provided at the bottom of the pulling wrench 91, and the long side of the L-shaped fixing block 92 passes through the groove. When the pulling wrench 91 moves back and forth, the long side of the L-shaped fixing block 92 will not come out of the groove. With this design, when the movable rod 5 is reset, the pulling wrench 91 can be reset by the L-shaped fixing block 92, eliminating the need for a reset torsion spring on the pulling wrench 91. Moreover, after the pulling wrench 91 is pulled outward, it can remain in the open state and not reset before the upper box separates from the lower box, providing the user with unlocking status information. The user can perceive whether the upper and lower boxes are locked by observing the posture of the pulling wrench 91.
[0057] In one embodiment, the enclosure interlock structure further includes a detachable housing portion 3 installed at the bottom of the enclosure. The mounting groove 31 and the third elastic member 34 are disposed within the housing portion 3, and the pushing block 4 is slidably disposed within the housing portion 3, so that the enclosure interlock structure as a whole forms an independently detachable and assembleable component. This design allows the enclosure interlock structure to be sold as a single, independent component, and during maintenance or replacement, the original enclosure interlock structure can be directly removed and replaced with a new one.
[0058] Preferably, the housing is provided with an assembly groove at the position corresponding to the housing part 3 for mounting the housing part 3.
[0059] In one embodiment, the slot 1 on one side of the corresponding housing part 3 at the bottom of the housing is provided on the housing part 3. This design results in higher overall precision and reduces the likelihood of misalignment between the push block 4 and the slot 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
[0061] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
