Description

Technical Field

[0001] This utility model relates to the field of locking connection technology, and in particular to a locking component and a toolbox containing the locking component. Background Technology

[0002] To provide different storage spaces, existing toolboxes are often designed as several separable boxes. In the assembled state, the individual boxes are connected and fixed by special structures or components, making several separate boxes into a whole. For example, plastic toolboxes have a special connection structure pre-set on each box to be integrated with the box body. This makes demolding during the one-piece injection molding process more difficult. If the commonly used hardware buckle lock is used, the installation is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0003] The technical problem this utility model aims to solve is that if the existing connection and locking structure of the injection molding toolbox is designed as an integral part of the box body, the injection molding demolding is quite difficult. Therefore, this utility model provides a locking component.

[0004] To solve the above-mentioned technical problems, this utility model provides a locking component for connecting and locking two separable objects, including a first locking structure and a second locking structure. The first locking structure includes a fixed hook and a first fixed end for fixing the first locking structure to one of the objects. The first fixed end is fixedly connected to the fixed hook and has an L-shaped structure. The hook portion of the fixed hook extends to the same side as the first fixed end. The second locking structure includes a movable hook and a second fixed end for fixing the second locking structure to the other object. The movable hook is swayably disposed at the second fixed end. When the two objects are in a state to be connected, the movable hook can swing and engage with the fixed hook, and locking is achieved by the interlocking of the hook portion of the movable hook with the hook portion of the fixed hook.

[0005] As a preferred embodiment, the first fixed end is inserted into a preset mounting hole A on the object and is fixed by a preset buckle A on the mounting hole A.

[0006] As a preferred embodiment, the fixing hook is provided with at least one through hole, which is used for the buckle A to pass through and engage with the first locking structure; the through hole is located near the connection between the fixing hook and the first fixing end.

[0007] As a preferred embodiment, the second fixed end is inserted into a pre-set mounting hole B on another object. Both ends of the second fixed end on the side away from the mounting hole B are provided with columnar terminals. The movable locking hook includes a locking hook part, a connecting terminal, and a connecting plate. The two ends of the connecting plate are respectively connected to the locking hook part and the connecting terminal. The connecting terminal is cylindrical and rotatably sleeved on the columnar terminal.

[0008] As a preferred embodiment, the cylindrical connecting terminal has a notch of less than 1 / 3 of an arc on its cylindrical wall. This allows the columnar terminal to be directly inserted into the cylindrical connecting terminal through the arc notch when the movable latch is connected to the second fixed end. This also facilitates disassembly, maintenance, and replacement when the movable latch is damaged.

[0009] As a preferred embodiment, the second fixed end is provided with at least one pair of buckles B. When the second locking structure is installed on the object, the pair of buckles B engages with the pre-set engagement groove in the mounting hole B. The pair of buckles B are arranged in parallel, and the distance between the engagement protrusions at the ends of the two buckles B is greater than the thickness of the second fixed end.

[0010] As a preferred embodiment, both the hook end of the fixed locking hook and the hook end of the movable locking hook are arc-shaped.

[0011] As a preferred embodiment, when two separable objects are combined together and in a locked state, the first fixed end and the second fixed end are arranged in parallel.

[0012] In addition, this utility model also provides a toolbox, including several separable boxes and a box cover, and also includes the locking component as described in the aforementioned solution; each of the boxes has a first locking structure and a second locking structure respectively provided on a pair of opposite side walls, the first locking structure being located near the lower middle of the box, and the second locking structure being located near the upper middle of the box; when adjacent boxes need to be connected and locked, the second locking structure located at the upper end of the lower box cooperates with the first locking structure located at the upper box to lock the two boxes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model designs the first locking structure and the second locking structure to be detachably connected to the locking component, and the connection method adopts a simple plug-in combination;

[0015] 2. The locking component with a split design in this utility model is used in injection molded toolboxes, which simplifies the toolbox mold design and makes demolding easier. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The present invention provides a locking component and a toolbox containing the locking component, the purpose of which is to provide a locking component that is easy to assemble and connect with an injection molded toolbox, thereby making the toolbox body injection mold design relatively simple and cost-effective, and making production demolding easier.

[0027] Example 1: Locking component

[0028] like Figures 1 to 5As shown, the present invention provides a locking member for connecting and locking two separable objects (such as the body of a toolbox). The locking member mainly includes a first locking structure 100 and a second locking structure 200.

[0029] In this embodiment, as shown in the figure, the first locking structure 100 is integrally injection molded from rigid plastic, including a first fixed end 110 and a fixed hook 120. The first fixed end 110 is plate-shaped and fixedly connected to the fixed hook 120, together forming an L-shaped structure. Of course, in order to reduce weight and save materials, the first fixed end can also be hollowed out in the middle to form a U-shape or a U-shape. The end of the fixed hook 120 is bent inward towards the inside of the L-shaped structure formed by it and the first fixed end 110 to form a hook portion 121, the cross-section of which is arc-shaped. The fixed hook 120 is provided with at least one through hole 130, the through hole 130 is used for the buckle A to pass through and engage with the first locking structure 100; the through hole 130 is located near the connection between the fixed hook 120 and the first fixed end 110.

[0030] In this embodiment, as Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the second locking structure 200 is also injection molded from rigid plastic, including a second fixed end 210 and a movable locking hook 220, and the second fixed end 210 and the movable locking hook 220 are connected in a detachable manner. The second fixed end 210 is plate-shaped, and its end facing the outside of the object has two parallel buckles B211. The two parallel buckles B211 are located on the upper and lower sides of the second fixed end, respectively. Each buckle B211 has an engaging protrusion. The engaging protrusions of the two buckles B211 are arranged in the upper and lower directions of the second fixed end 210. The distance between the engaging protrusions at the ends of the two buckles B211 is greater than the thickness of the plate body of the second fixed end 210 to form an elastic engaging structure. A columnar terminal 212 extends from both ends of the side of the second fixed end 210 away from the buckles B211 in the length direction of the second fixed terminal.

[0031] Specifically, such as Figure 5As shown, the movable locking hook 220 includes a cylindrical connecting terminal 221, a locking hook portion 223, and a connecting plate 222 that fixes the connecting terminal 221 and the locking hook portion 223 together. The connecting terminal 221 is rotatably sleeved on the columnar terminal 212 of the second fixed end 210, so that the entire movable locking hook 220 can swing about the columnar terminal 212 as the axis. The connecting plate 222 can be slightly arc-shaped, which can enhance the range of elastic deformation of the connecting plate 222. The length of the connecting plate 222 should be such that the movable locking hook can be tightly engaged with the fixed locking hook after swinging. The end of the locking hook portion 223 is also bent to form an arc-shaped hook portion. In this way, the contact surfaces of the locking hook portion 223 and the hook portion 121 are not arc-shaped during the engagement process, so that the movable locking hook and the fixed locking hook will not get stuck during engagement or disengagement.

[0032] The first locking structure 100 and the second locking structure 200 are respectively installed on the two objects to be connected through their fixed ends. In this way, the two objects to be connected can be locked together by the first locking structure 100 and the second locking structure 200.

[0033] Specifically, the first fixed end 110 of the first locking structure 100 is inserted into a preset mounting hole A on the first object, and a buckle A (not shown in the figure) is provided in the mounting hole A. When the first fixed end 110 is inserted into place, the buckle A in the mounting hole A passes through the through hole 130 and engages with the edge of the through hole 130, thereby firmly fixing the first locking structure 100 to the object.

[0034] In this embodiment, the second fixing end 210 of the second locking structure 200 is inserted into a pre-set mounting hole B on the second object. The mounting hole B is provided with a locking groove (not shown in the figure) that matches the buckle B211. When the second fixing end 210 is inserted into the mounting hole B, a pair of buckles B211 are compressed and undergo elastic deformation until the locking protrusion at their ends aligns with the locking groove in the mounting hole B and engages therein, thereby firmly fixing the second locking structure 200 to the second object.

[0035] When it is necessary to connect and lock two objects, bring the two objects close together so that the fixed locking hook 120 of the first locking structure 100 corresponds to the movable locking hook 220 of the second locking structure 200. Move the movable locking hook 220 so that it swings upwards (i.e., towards the fixed locking hook 120) around the cylindrical terminal 212. The arc-shaped hook portion 223 of the movable locking hook 220 moves accordingly and contacts, slides past, and finally engages with the arc-shaped hook portion 121 of the fixed locking hook 120, locking them together. Figure 4 The state shown indicates that the two objects are securely locked together. In this locked state, the first fixed end 110 and the second fixed end 210 are parallel.

[0036] When it is necessary to separate two objects, the movable locking hook 220 is reversed so that its hook 223 disengages from the hook 121 of the fixed locking hook 120, and the two objects can be separated.

[0037] Example 2: Toolbox

[0038] like Figures 6-7 As shown, the present invention also provides a toolbox, which includes a lid 400, a plurality of separable boxes (such as a first box 510 and a second box 520) and a locking element as described above.

[0039] At the lower center of the lower end of a pair of opposing sidewalls of the first housing 510, a first locking structure 100 is provided. Specifically, the first locking structure 100 is inserted into a pre-set mounting hole A10 on the housing through a first fixing end 110. The buckle A in the mounting hole A10 passes through the through hole 130 and engages with the edge of the through hole 130. At the upper center of the upper end of the sidewall of the second housing 520 corresponding to the first housing 510, a second locking structure 200 is provided. Specifically, the second fixing end 210 is inserted into the mounting hole B20. A pair of buckles B211 are compressed and undergo elastic deformation until the engaging protrusions at their ends align with the engaging grooves in the mounting hole B20 and engage therein, thereby firmly fixing the second locking structure 200 to the housing.

[0040] It should be noted that the depth direction of mounting hole A is from the bottom of the box upwards, and the depth direction of mounting hole B is from the outside of the box inwards.

[0041] When the first box 510 and the second box 520 need to be stacked, the second box 520 is placed on top of the first box 510, and the second locking structure 200 on the second box 520 is aligned with the first locking structure 100 on the first box 510. Then, as described in Embodiment 1, each movable locking hook 220 is sequentially moved to engage with its corresponding fixed locking hook 120, thus completing the locking between the boxes. The box lid 400 can be connected to the topmost box by using a similar locking mechanism with a first locking structure or a conventional hinge structure.

[0042] This toolbox achieves quick and reliable connection and separation between the boxes through the aforementioned locking components. It has a simple structure and is easy to operate.
