Technical Field

[0001] The utility model relates to the technical field of toolboxes, in particular to a stacking and positioning device for a push-pull toolbox. Background Technique

[0002] There are many toolboxes in the prior art that are set to be stackable, and several toolboxes can be stacked and fixed, increasing the storage space for tools and enabling the stacking of toolboxes according to the required number of tools.

[0003] In the related art, through retrieval, it is found that in a solution of a stackable toolbox that can be pushed and pulled (publication number CN216030715U), a push-pull rod is arranged on the bottom box, and an upper box is placed on the bottom box to increase the placement space for tools. The bottom box is used as both a toolbox and a load-bearing plate, eliminating the need for a load-bearing plate, reducing the weight, and having a good load-bearing effect.

[0004] However, in the above solution, the adjacent boxes are connected by two buckles. When the boxes are stacked, when separating the boxes, it is necessary to manually separate the box and the buckle first, and then move the box, which still has deficiencies in terms of operation convenience. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stacking and positioning device for a push-pull toolbox to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A stacking and positioning device for a push-pull toolbox, including a second box body, a box cover is installed at the upper end of the second box body, and locking grooves are provided on the left and right sides of the lower surface of the second box body;

[0007] Support seats are installed on both the left and right sides of the box cover, a locking member is rotatably installed inside the support seat, the size of the locking member corresponds to that of the locking groove, the locking member has an inclined surface, and the inclined surface has a groove;

[0008] A buckle, the buckle is rotatably installed on the left and right sides of the lower surface of the second box body, and the size of the buckle corresponds to that of the groove;

[0009] When two second box bodies are stacked, the locking member is inserted into the locking groove and the buckle is inserted into the groove to assemble the two second box bodies. Pulling up the buckle upwards pushes the locking member to separate from the locking groove, splitting the two second box bodies, with more convenient operation and more convenient use.

[0010] Furthermore, a telescopic handle is installed on the side of the first box body, and rollers are installed on both side surfaces of the telescopic handle. The telescopic handle is flexible to use, convenient to move through the rollers, and occupies little space after being shortened.

[0011] Furthermore, the corners of the box cover are provided with positioning grooves, and the lower surface of the second box body is provided with positioning feet corresponding to the positioning grooves, which improves the stability of stacking the first box body, the second box body, and the third box body and prevents misalignment.

[0012] Furthermore, the locking member is provided with a bracket integrally formed with the locking member. The bracket and the locking member can stably hold the locking groove, and the first box body, the second box body, and the third box body are not easily loosened after being stacked.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the second box body is placed on the first box body, the locking groove pushes open the locking member through the inclined surface of the locking member, ensuring that the locking member smoothly snaps into the inside of the locking groove, realizing the automatic locking of the first box body and the second box body. At this time, the trigger is inserted into the groove to prevent the locking member from rotating and ensure that the stacked first box body and the second box body will not be accidentally separated; when separating the first box body and the second box body, when moving the second box body, the trigger is conveniently held, and the trigger pushes the locking member to separate from the locking groove, reducing the operation steps and making it more flexible and convenient to use.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0022] Please refer to Figure 1-6 , the present utility model provides a technical solution: a stacking clamping device for a push-pull toolbox, including a second box body 2, a box cover 5 is installed at the upper end of the second box body 2, locking grooves 11 are provided on the left and right sides of the lower surface of the second box body 2, and the second box body 2 is injection molded with strong load-bearing capacity;

[0023] Support seats 8 are installed on both the left and right sides of the box cover 5, a locking member 6 is rotatably installed inside the support seat 8, the size of the locking member 6 corresponds to that of the locking groove 11, the locking member 6 has an inclined surface with a groove 13, and pressing the inclined surface of the locking groove 11 can push the locking member 6 to rotate to ensure that the locking member 6 can be smoothly stuck into the locking groove 11;

[0024] A trigger 10, the trigger 10 is rotatably installed on the left and right sides of the lower surface of the second box body 2, and the size of the trigger 10 corresponds to that of the groove 13;

[0025] When two second box bodies 2 are stacked, the locking member 6 is inserted into the locking groove 11 and the trigger 10 is inserted into the groove 13 to assemble the two second box bodies 2. Pulling up the trigger 10 can push the locking member 6 to separate from the locking groove 11, making it more convenient to disassemble the two second box bodies 2.

[0026] In this embodiment, as Figure 1 and Figure 2 shown, it further includes a first box body 1 and a third box body 3, and box covers 5 and triggers 10 are also installed on the first box body 1 and the third box body 3, so that the first box body 1, the second box body 2, and the third box body 3 are stacked from bottom to top, simplifying the stacking operation method and having better usability.

[0027] In this embodiment, as Figure 1 and Figure 2 shown, a telescopic handle 14 is installed on the side of the first box body 1, and rollers 4 are installed on both side surfaces of the telescopic handle 14. When the telescopic handle 14 is not in use, the telescopic handle 14 can be shortened, and pulling out the telescopic handle 14 and cooperating with the rollers 4 for dragging is more labor-saving and convenient.

[0028] In this embodiment, as Figure 2 and Figure 3As shown, the corner of the box cover 5 is provided with a positioning groove 7, and the lower surface of the second box body 2 is provided with a positioning foot 15 corresponding to the positioning groove 7, ensuring that the first box body 1, the second box body 2, and the third box body 3 can be automatically aligned when stacked and playing a role in preventing sliding.

[0029] In this embodiment, as Figure 4 shown, the side of the locking member 6 is provided with an arc-shaped groove 9, and the arc-shaped groove 9 is movably connected to the support seat 8. The arc-shaped groove 9 improves the flexibility of the movement of the locking member 6. When the locking groove 11 presses down the locking member 6, the locking groove 11 is not prone to jamming during rotation.

[0030] In this embodiment, as Figure 5 shown, the locking member 6 is provided with a support seat 12 integrally formed with the locking member 6. The locking member 6 and the support seat 12 can clamp the locking groove 11, and the stacking of the first box body 1, the second box body 2, and the third box body 3 is more firm.

[0031] Specifically, during use, the second box body 2 is stacked on the first box body 1. The locking groove 11 of the second box body 2 presses down the inclined surface of the locking member 6, thereby pushing the locking member 6 to rotate in the support seat 8, making preparations for the locking member 6 to enter the locking groove 11. During the process of the second box body 2 falling onto the cover plate of the first box body 1, the buckle 10 presses into the groove 13 and drives the locking member 6 to rotate, ensuring that the locking member 6 smoothly inserts into the locking groove 11. Therefore, the second box body 2 can be automatically locked when stacked on the first box body 1;

[0032] When it is necessary to separate the second box body 2 and the first box body 1, both hands are buckled on the two buckles 10. The buckles 10 rotate and drive the locking member 6 to rotate through the groove 13, separating the locking member 6 and the locking groove 11. There is no need to specifically rotate the locking member 6, and the second box body 2 can be naturally moved to be separated from the first box body 1. The stacking of the third box body 3 and the second box body 2 is the same as the principle of the second box body 2 being stacked on the first box body 1. The stacking and separation of the first box body 1, the second box body 2, and the third box body 3 are more convenient.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
