Description

Technical Field

[0001] This utility model relates to the field of stacked toolbox technology, specifically to a quick-release stacked toolbox. Background Technology

[0002] Stackable toolboxes maximize vertical space utilization and minimize surface area occupied, making them especially suitable for small apartments or spaces with limited capacity. Their modular design allows for easy stacking, splitting, or height adjustment to accommodate different item sizes and storage needs. By using stackable toolboxes effectively, users can significantly improve space efficiency while maintaining a clean and organized environment, making them suitable for various scenarios including living, working, and commercial settings.

[0003] A quick-release, stackable toolbox, disclosed in CN202310110719.X, comprises toolboxes stacked vertically, with the bottom of the upper box and the top of the lower box connected together. The toolbox includes a top shell and a bottom shell connected by snap-fit ​​fasteners. The top shell has hooks on both sides of its upper surface, and the bottom of one side of the bottom shell has a movable groove. The other side of the bottom shell has a hook. This design allows for quick and easy assembly of the toolbox, which previously required multiple stacking steps, through the combination of fixed and movable hooks. The disassembly function is simple; installation only requires a tilted, direct press, allowing for quick fixing and disassembly of stacked toolboxes. The device features a handle limiting hole and a guide plate that slides along the handle limiting hole. The guide plate extends to the inside of the toolbox. During use, if the handle limiting hole is obstructed, such as by fabric, it may be impossible to disassemble adjacent toolboxes by pulling the handle. The toolbox body must be opened first, and the obstruction removed before the adjacent toolboxes can be released and disassembled, affecting the user experience.

[0004] Therefore, it is necessary to invent a quick-release stackable toolbox to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-release stackable toolbox. This solves the problem that in actual use, the horizontal sliding opening and closing mechanism may result in a large force-bearing area during transmission. When an external force impacts and presses any position of the button, the upper and lower boxes may fall off, causing damage to items and affecting the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release stackable toolbox includes a lower box and an upper box. One end of the lower box is hinged to a body latch for closing the upper box. The side of the lower box is hinged to an external latch for engaging an adjacent upper box. The external latch has a pressing part on one side of its hinge shaft and a engaging part on the other side. The external latch also has an elastic element for driving the engaging part to engage with the adjacent box.

[0008] As a preferred embodiment of this utility model, external hooks are provided on both sides of the top of the upper box, and a bottom block is provided on one side of the bottom of the lower box; when adjacent tool boxes are engaged, the engaging part and bottom block of one tool box are engaged with the corresponding external hooks of the other tool box.

[0009] As a preferred embodiment of this utility model, a top limiting block is provided at the top of the upper box and a bottom support block is provided at the bottom of the lower box. When adjacent tool boxes are engaged, the inner edge of the bottom support block cooperates with the outer edge of the top limiting block.

[0010] As a preferred embodiment of this utility model, four bottom support blocks are provided, each located at the corner of the lower box; when adjacent toolboxes are engaged, the bottom locking blocks are located inside the upper and lower boxes.

[0011] As a preferred embodiment of this utility model, the opening direction of the external hook faces outward, and the opening direction of the locking part and the bottom locking block faces inward.

[0012] As a preferred embodiment of this utility model, the elastic element includes a second spring slot, a second spring groove, and a return spring located inside both. The second spring slot is located in the middle of the side where the external buckle of the lower box is located, and the second spring groove is located inside the external buckle. The positions of the second spring groove and the second spring slot correspond to each other.

[0013] As a preferred embodiment of the present invention, the pressing part includes a limiting block, a guide block two, and a pressing end face located outside the external buckle. The limiting block is located on one side of the spring slot two, and the guide block two is located on one side of the spring slot two.

[0014] As a preferred embodiment of this utility model, hinge posts are provided on both sides of the external buckle, and the lower box body is provided with pivot slots on both sides of the spring slot two to facilitate the installation of the hinge posts. A slot is provided on the inner side of the external buckle to facilitate the inward retraction of the hinge posts.

[0015] As a preferred embodiment of this utility model, the lower box body and the upper box body are connected by a body buckle. The upper box body has a body hook on the side facing the body buckle. The top of the body buckle has a body block that can engage with the body hook. An elastic element for driving the body buckle to engage with the lower box body is provided between the body buckle and the lower box body. A guide block is installed on the inner side of the body buckle. A hinge shaft slot penetrating the body buckle is opened on one side of the guide block. When the end face of the guide block is in contact with the end face of the lower box body, the body buckle is in a locked state.

[0016] As a preferred embodiment of this utility model, the hinge joint between the lower box and the upper box is provided with a hook for easy hanging on the wall.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] In this invention, by optimizing the structure of the external buckle, pressing the upper half of the external buckle causes it to rotate around the hinge post, rotating the locking part outward and separating it from the external hook, facilitating the disassembly of the lower box from the adjacent upper box. Simultaneously, the design of rotating around the hinge post reduces the area of ​​the external buckle's contact surface, preventing the toolboxes from separating and falling off due to impacts or pressure during transport. The hinge design ensures complete separation of the external buckle from the toolbox's interior, preventing obstruction or other factors from hindering the disassembly of adjacent toolboxes.

[0019] After the pressure applied to the external buckle is released, the external buckle can be brought into contact with the guide block two and the limit block under the action of the spring, so that the external buckle is in a vertical state. When assembling adjacent tool boxes, the bottom block and the external hook engage with each other. By pressing the top tool box, the engagement part is supported, so that the top tool box and the bottom tool box engage with each other, reducing the difficulty of stacking and assembling tool boxes.

[0035] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0036] This utility model provides, for example Figure 1-10The illustrated quick-release stackable toolbox includes a lower box body 1 and an upper box body 2. One end of the lower box body 1 is hinged to a body latch 3 for closing the upper box body 2. The side of the lower box body 1 is hinged to an external latch 4 for engaging adjacent upper box bodies 2. The external latch 4 has a pressing part 405 on one side of its hinge axis and a engaging part 401 on the other side. The external latch 4 also has an elastic element for driving the engaging part 401 to engage with the adjacent box body. By pressing the pressing part 405, the opening and closing of the engaging part 401 can be controlled, enabling quick disassembly of adjacent toolboxes. The elastic element allows the external latch 4 to quickly reset after disassembly or after the adjacent toolboxes are assembled by pressing, thus securing the adjacent toolboxes together. This reduces the steps involved in assembling adjacent toolboxes and lowers the difficulty of operation.

[0037] External hooks 202 are provided on both sides of the top of the upper box 2, and a bottom latch 102 is provided on one side of the bottom of the lower box 1. When adjacent tool boxes are engaged, the latching part 401 and the bottom latch 102 of one tool box engage with the corresponding external hooks 202 of the other tool box. The bottom latch 102 and the latching part 401 in the reset state are symmetrically arranged around the middle of the tool box, so it is not necessary to distinguish the left and right sides of the tool box during the assembly process.

[0038] The upper box 2 has a top limiting block 201 at its top, and the lower box 1 has a bottom support block 101 at its bottom. When adjacent toolboxes are engaged, the inner edge of the bottom support block 101 engages with the outer edge of the top limiting block 201. Four top limiting blocks 201 are provided to position and guide the bottom support blocks 101. The end face of the top limiting block 201 is provided with a slope to guide the lower box 1 when tilted.

[0039] Four bottom support blocks 101 are provided, located at the corners of the lower box 1 respectively; when adjacent toolboxes are engaged, the bottom locking blocks 102 are located inside the upper box 2 and the lower box 1. The bottom support blocks 101 are located at the four corners of the lower box 1, which also facilitates the placement of toolboxes.

[0040] The external hook 202 has its opening facing outwards, while the locking part 401 and the bottom locking block 102 have their openings facing inwards. The external hook 202 is also designed to be elongated to ensure the locking effect of adjacent toolboxes and reduce the difficulty of loosening.

[0041] The elastic element includes a second spring slot 105, a second spring groove 403, and a return spring located inside both. The second spring slot 105 is located in the middle of the side where the external latch 4 is located on the lower box 1, and the second spring groove 403 is located inside the external latch 4. The positions of the second spring groove 403 and the second spring slot 105 correspond. By applying an elastic force to the second spring groove 403 through the return spring, and by the abutment of the second guide block 402, the external latch 4 can be returned to a state where its end face is flush with the end face of the tool box, ensuring a locking effect.

[0042] The pressing part 405 includes a limiting block 107, a guide block 402, and a pressing end face located outside the external latch 4. The limiting block 107 is located on one side of the spring slot 105, and the guide block 402 is located on one side of the spring groove 403. The limiting block 107 and the guide block 402 cooperate with each other to prevent the external latch 4 from tilting to one side under the action of the spring, keeping it in the reset state, which facilitates the assembly of the tool box below. The pressing part 405 is provided with anti-slip stripes to optimize the pressing feel. In the reset state, the end faces of the main latch 3 and the external latch 4 are both in contact with the end face of the lower box body 1.

[0043] The external snap fastener 4 has hinge posts 404 on both sides. The lower housing 1 has pivot slots 106 on both sides of the spring slot 105 to facilitate the installation of the hinge posts 404. The inner side of the external snap fastener 4 has a slot to facilitate the inward retraction of the hinge posts 404. The slot on the inner side of the external snap fastener 4 facilitates the insertion of the hinge posts 404 into the pivot slots 106.

[0044] The lower box 1 and the upper box 2 are engaged by a body latch 3. A body hook 203 is provided on the side of the upper box 2 facing the body latch 3. A body locking block 303 is provided at the top of the body latch 3 to engage with the body hook 203. An elastic element 2 is provided between the body latch 3 and the lower box 1 to drive the body latch 3 to engage with the upper box 2. The elastic element 2 ensures that the lower box 1 and the upper box 2 remain engaged, preventing them from falling off.

[0045] The hinge between the lower box 1 and the upper box 2 is equipped with a hook 5 for easy wall mounting. The hook 5 allows the toolbox to be stored on the wall, avoiding taking up workspace on the workbench.

[0046] This invention optimizes the structure of the external buckle 4, allowing it to rotate around the hinge post 404 by pressing its upper end. This causes the locking part 401 to rotate outwards, separating it from the external hook 202 and facilitating the disassembly of the lower box 1 from the adjacent upper box 2. Simultaneously, the design of rotating around the hinge post 404 reduces the area of ​​the external buckle 4's contact surface, preventing toolboxes from separating and falling due to impacts or pressure during transport. The hinge design ensures complete separation of the external buckle 4 from the toolbox interior, preventing obstruction and other factors that could hinder the disassembly of adjacent toolboxes.

[0047] After the pressure applied to the external buckle 4 is released, the external buckle 4 can abut against the guide block 402 and the limit block 107 under the action of the spring, so that the external buckle 4 is in a vertical state. When assembling adjacent tool boxes, the bottom latch 102 and the external hook 202 are engaged with each other. By pressing the top tool box, the latching part 401 is supported, so that the top tool box and the bottom tool box are engaged with each other, reducing the difficulty of stacking and assembling tool boxes.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
