DETAILED DESCRIPTION

[0024] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0025] The embodiment of the present application provides a tool box 10, such as Figure 1 , Figure 3 and Figure 4 As shown, the tool box 10 includes: a base 100, a cover 200 and a shock absorbing assembly 300. The cover 200 is rotatably connected to the base 100, and the cover 200 and the base 100 can enclose and form a receiving space. The cover 200 and the base 100 are provided with a workpiece groove 220, which is used to receive tools and is engaged with the tools. The shock absorbing assembly 300 is located between the base 100 and the cover 200, and the shock absorbing assembly 300 is rotatably connected to the cover 200.

[0026] In this embodiment, the cover 200 and the base 100 are both box structures with one side open, and the openings of the two are arranged oppositely, that is, the opening of the cover 200 is located at the bottom, and the opening of the base 100 is located at the top. One end of the cover 200 is rotatably connected to one end of the base 100. When the cover 200 is rotated to a position covering the top of the base 100, the tool box 10 is in a closed state, and a storage space is enclosed between the cover 200 and the base 100. The storage space can accommodate tools. For example, the tools can be maintenance tools for relays. When the cover 200 is rotated to a position avoiding the top of the base 100, the tool box 10 is in an open state, and the operator can count and take the tools.

[0027] The cover 200 and the base 100 are provided with workpiece slots 220 capable of accommodating tools. There are multiple tools and workpiece slots 220, and they correspond one to one. The shape of any workpiece slot 220 is adapted to the shape of the corresponding tool. When the tool is stored in the workpiece slot 220, the workpiece slot 220 is engaged with the tool to position the tool and prevent the tool from falling off.

[0028] When the tool box 10 is in a closed state, the shock absorbing assembly 300 is located between the base 100 and the cover 200. The shock absorbing assembly 300 can prevent the tools on the base 100 and the cover 200 from colliding with each other, and provide shock absorption for the tools on both sides. When the tool box 10 is in an open state, the shock absorbing assembly 300 can be rotated toward the cover 200 to count and take the tools on the base 100.

[0029] Exemplarily, the seat body 100, the cover body 200 and the shock absorbing assembly 300 may be rotatably connected via the same hinge shaft, or may be hinged via two different hinge shafts.

[0030] The tools are stored in the cover 200 and the workpiece slot 220 on the base 100, which expands the storage space for the tools, improves the adaptability and stability of the tool storage, and makes the tool storage neat and convenient, which is convenient for counting and taking the tools, saves the time for job preparation and tool management, and improves the efficiency of job preparation and tool management. The shock absorbing assembly 300 prevents the upper and lower tools from colliding with each other and causing damage, and at the same time makes the tools not easy to fall off in the workpiece slot 220, thereby ensuring the service life of the tools.

[0031] In some embodiments provided in this application, Figure 2 As shown, optionally, the shock absorbing assembly 300 includes: a buffer shell 310 and an elastic member 320, the buffer shell 310 is rotatably connected to the cover body 200, a buffer cavity 311 is formed in the buffer shell 310, the elastic member 320 is located in the buffer cavity 311, and both ends of the elastic member 320 are respectively connected to the top wall and the bottom wall of the buffer shell 310, the top wall is opposite to the cover body 200, and the bottom wall is opposite to the seat body 100.

[0032] In this embodiment, one end of the buffer shell 310 is rotatably connected to one end of the cover body 200, and a buffer cavity 311 is formed between the top wall and the bottom wall of the buffer shell 310, wherein the top wall and the bottom wall are respectively arranged opposite to the cover body 200 and the base body 100. An elastic member 320 is arranged in the buffer cavity 311, and the two ends of the elastic member 320 are respectively connected to the top wall and the bottom wall of the buffer shell 310. The buffer shell 310 can generate a slight elastic deformation through the internal buffer cavity 311, and cooperate with the internal elastic member 320 to provide shock absorption and buffering when the tools collide, thereby providing protection for the tools on both sides.

[0033] Exemplarily, the elastic member 320 may be a spring.

[0034] In some embodiments provided in this application, Figure 2 As shown, optionally, the shock absorbing assembly 300 also includes: a positioning cylinder 330 and a sliding rod 340, the positioning cylinder 330 is connected to the bottom wall of the buffer shell 310, the sliding rod 340 is slidably connected to the positioning cylinder 330, and the two ends of the sliding rod 340 are respectively connected to the elastic member 320 and the top wall of the buffer shell 310.

[0035] In this embodiment, the positioning tube 330 is connected to the bottom wall of the buffer shell 310, and the axis of the positioning tube 330 extends from the bottom wall of the buffer shell 310 toward the top wall. Figure 2 X in the middle is the axis of the positioning cylinder 330. The sliding rod 340 is located between the elastic member 320 and the top wall of the buffer shell 310. The two ends of the sliding rod 340 are respectively connected to the top of the elastic member 320 and the top wall of the buffer shell 310. When the sliding rod 340 slides along the wall of the positioning cylinder 330, it drives the elastic member 320 to produce elastic deformation, thereby controlling the deformation direction of the elastic member 320 and the buffer shell 310, so that the elastic member 320 and the buffer shell 310 are deformed in the up and down height direction, thereby improving the buffering effect of the shock absorbing assembly 300 on both sides and improving the buffering stability of the shock absorbing assembly 300.

[0036] In a possible embodiment, the elastic member 320 is located inside the positioning tube 330 , and the sliding rod 340 is slidably connected to the inner wall of the positioning tube 330 .

[0037] In another possible embodiment, the elastic member 320 is located outside the positioning tube 330 , and the sliding rod 340 is slidably connected to the outer wall of the positioning tube 330 .

[0038] In some embodiments provided in this application, Figure 2 As shown, optionally, a through hole 331 is provided on the positioning cylinder 330, and the sliding rod 340 passes through the through hole 331 and extends into the positioning cylinder 330. A boss 341 is provided at the end of the sliding rod 340, and the boss 341 is located in the positioning cylinder 330 and can be clamped with the top wall of the positioning cylinder 330.

[0039] In this embodiment, a through hole 331 is provided on the top wall of the positioning cylinder 330, and the bottom end of the sliding rod 340 passes through the through hole 331 and extends into the positioning cylinder 330. A boss 341 is provided at the bottom end of the sliding rod 340. Figure 2The arrow at the Y in the middle points to the radial direction of the sliding rod 340, and the boss 341 extends outward along the radial direction of the sliding rod 340. The boss 341 is located in the positioning cylinder 330. When the sliding rod 340 moves upward, the boss 341 can be engaged with the top wall of the positioning cylinder 330 to limit the sliding rod 340 when it moves upward, so as to prevent the sliding rod 340 from being separated from the positioning cylinder 330. In addition, the boss 341 expands the bottom end area of ​​the sliding rod 340, which facilitates the connection between the sliding rod 340 and the elastic member 320.

[0040] In some embodiments provided in this application, Figure 2 As shown, optionally, the shock absorbing assembly 300 also includes: a top plate 350 and a bottom plate 360, the top plate 350 is connected to the top wall of the buffer shell 310, the bottom plate 360 ​​is connected to the bottom wall of the buffer shell 310, the top plate 350 and the bottom plate 360 ​​are arranged in the buffer cavity 311, and the two ends of the elastic member 320 are respectively connected to the top plate 350 and the bottom plate 360.

[0041] In this embodiment, a top plate 350 and a bottom plate 360 ​​are respectively provided on the top wall and the bottom wall of the buffer shell 310, and the material hardness of the top plate 350 and the bottom plate 360 ​​is greater than the material hardness of the buffer shell 310. The top plate 350 and the bottom plate 360 ​​are located in the buffer cavity 311, which not only ensures the buffer function of the buffer shell 310, but also provides support for the buffer shell 310, thereby improving the stability of the shock absorbing assembly 300. The two ends of the elastic member 320 are respectively connected to the buffer shell 310 through the top plate 350 and the bottom plate 360, thereby improving the strength of the connection position of the elastic member 320 and preventing the connection from affecting the buffer effect of the buffer shell 310.

[0042] Exemplarily, the top of the sliding rod 340 is connected to the top plate 350 , and the positioning cylinder 330 is connected to the bottom plate 360 ​​.

[0043] In some embodiments provided in this application, Figure 2 As shown, optionally, there are multiple positioning cylinders 330, and the multiple positioning cylinders 330 form a rectangular array.

The number of positioning cylinders 330 in any row is the same, and the spacing between adjacent positioning cylinders 330 is the same. The number of positioning cylinders 330 in any column is the same, and the spacing between adjacent positioning cylinders 330 is the same. The row spacing and column spacing between two adjacent rows and columns are respectively the same, so that the positioning cylinders 330 are distributed in a rectangular array, and the positioning cylinders 330 correspond one-to-one with the elastic members 320, thereby improving the uniformity of the distribution of the positioning cylinders 330 and the elastic members 320, avoiding large local deformation of the buffer shell 310, and improving the buffering uniformity of the shock absorbing assembly 300.

[0045] Exemplarily, the number of the positioning cylinders 330 may be 4, 9 or 12.

[0047] In this embodiment, a nameplate 400 is provided on the cover 200, and a display unit 410 is provided on the nameplate 400. The display unit 410 can display the model information of all tools, and the model information can include the size and specification information of the tools. The display unit 410 corresponds to the tool one by one, and the tool type in the tool box 10 can be obtained through the display unit 410, which is convenient for finding and counting the tools, thereby improving the efficiency of tool management.

[0048] For example, the display portion 410 may be cut and engraved on the nameplate 400 , or the model information may be directly sprayed on the nameplate 400 .
