Technical Field

[0001] The utility model relates to the technical field of toolboxes, in particular to a novel toolbox stacking self-locking device. Background Art

[0002] A toolbox is a container for storing tools and can be used for various purposes such as production, household, repair, fishing, etc., and is widely used. It is divided into a mobile type and a fixed type.

[0003] When toolboxes are stacked or placed in other ways, they need to be stacked on top of each other. Generally, they are stacked vertically. However, this stacking method is very likely to fall during transportation. At this time, the side insertion method is used to fix two toolboxes. Although this fixing method can effectively avoid the risk of falling when transporting toolboxes, for example, when using a trolley to transport toolboxes, several toolboxes are generally stacked. When encountering a gravel road or an uneven road, the stacked toolboxes above and below will have the risk of falling, and there will also be a certain risk of falling when fixing the toolboxes from the side. In order to completely solve the problem of toolboxes falling during small-scale transportation, a novel toolbox is needed to solve the above problems. Summary of the Utility Model

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0025] Please refer to Figures 1 to 7 , a novel toolbox stacking self-locking device provided by an embodiment of the present utility model includes: a box body 1 and a box cover 2 installed on the box body 1, a sliding locking assembly installed on the box body 1 and the box cover 2, the sliding locking assembly including a first fixing member installed on the box body 1 and a first mating member installed on the box cover 2, or the sliding locking assembly including a second mating member installed on the box body 1 and a second fixing member installed on the box cover 2; a self-locking assembly installed on the box body 1 and the box cover 2, the self-locking assembly including a self-locking member installed on the box body 1 and a limiting member installed on the box cover 2.

[0026] In this embodiment, when two toolboxes are stacked, the upper toolbox is pushed above the lower toolbox, so that the sliding locking assembly locks the two toolboxes. At this time, when the two toolboxes shake, they may also fall from the side. When the toolbox is locked by pushing, at this time, the self-locking assembly can prevent the two toolboxes from shaking and slipping from the side, so that self-locking can be achieved.

[0027] The self-locking component includes a placement groove formed on the bottom surface of the box body 1. An active component and a plug component that cooperates with the active component are installed in the placement groove. A first energy storage component is installed on the plug component. The self-locking component further includes a clamping component. The plug component can be used to limit the clamping component. A second energy storage component is also installed on the clamping component. The active component includes a movable shaft installed in the placement groove and a locking tongue 9 installed on the movable shaft. The plug component includes a movable shell 5 slidably installed in the placement groove. A plug board 12 is installed on one side of the movable shell 5. A convex block 10 that can be used to move the movable shell 5 is installed on the locking tongue 9. The active component is installed inside the movable shell 5.

[0028] The first energy storage component is a first spring 8 installed on the movable shell 5. One end of the first spring 8 is installed on the movable shell 5, and the other end of the first spring 8 is installed on the placement groove. The installation position of the first spring 8 is away from the position of the plug board 12.

[0029] The clamping component is a connection block 6 movably installed on the placement groove. The connection block 6 can be inserted into the limiting component. A fixing groove is formed on the connection block 6. The plug board 12 is adapted to the fixing groove.

[0030] The second energy storage component is a second spring 7 installed on the connection block 6. The other end of the second spring 7 is connected to the placement groove. An unlocking groove 11 is formed on the connection block 6.

[0031] The limiting component is a limiting groove formed on the box cover 2. The connection block 6 can be inserted into the limiting groove.

[0032] In this embodiment, when two toolboxes are installed, the upper toolbox is slidably installed above the lower toolbox. During the sliding process, when the locking tongue 9 is in close contact, it will drive the movable shaft to rotate. The convex block 10 of the movable shaft will touch the movable shell 5, so that the movable shell 5 will move. At this time, the plug board 12 will be withdrawn from the fixing groove, and the connection block 6 will push the connection block 6 downward to the box cover 2 of the lower toolbox due to gravity and the second spring 7. At this time, the connection block 6 will be directly above the limiting groove, and the connection block 6 will automatically fall, so that it can be inserted and connected, avoiding the problem that the upper toolbox falls from above when the two toolboxes are stacked, and completely solving the problem.

[0033] When unlocking is required, only need to manually lift the connection block 6. The unlocking groove 11 is a groove provided for cooperating with manual lifting. When pulling the upper toolbox, the entire toolbox can be pulled out. At the same time, the first spring 8 will push the entire movable shell 5, and the plug board 12 will be inserted into the fixing groove and then effectively fixed, so that it can be accurately reset, which does not affect the second use. The device is simple to use, and the cooperation of the sliding locking component and the self-locking component can effectively fix the two toolboxes.

[0034] The first fixing member is a first support block installed on the box body 1, and a first card slot 3 is formed on the first support block; the first mating member is a first positioning slot formed on the box cover 2, and a first retaining bar 4 adapted to the first card slot 3 is installed on the first positioning slot; the second fixing member is a second support block installed on the box cover 2, and a second card slot is formed on the second support block; the second mating member is a second positioning slot formed on the box body 1, and a second retaining bar adapted to the second card slot is installed on the second positioning slot.

[0035] In this embodiment, a first card slot 3 is formed on the first support block of the upper box body 1, and then the upper box body 1 is pushed on the box cover 2 of the lower box body 1. When pushing, the first retaining bar 4 on the box cover 2 of the lower box body 1 is inserted into the first card slot 3, so that the two box bodies 1 can be effectively fixed and prevented from falling off from the other side when shaking.

[0036] Alternatively, a second card slot is formed on the second support block of the lower box body 1, and then the upper box body 1 is pushed on the box cover 2 of the lower box body 1. When pushing, the second retaining bar on the box cover 2 of the upper box body 1 is inserted into the second card slot, so that the two box bodies 1 can be effectively fixed and prevented from falling off from the other side when shaking.

[0037] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
