Support components 3 are installed on the inner sides of both sides of the top of the cabinet 1, and the support components 3 can rotate and provide lifting force to connect the support components 3 with the bottom of the tool box 4. Under normal circumstances, the tool box 4 is located on the top of the cabinet 1 and overlaps with it. When the tool box 4 needs to be raised, some parts of the support component 3 can be rotated by pulling the tool box 4, and the tool box 4 can be quickly rotated and raised from the top of the cabinet 1 by thrust. At the same time, the tool box 4 deviates to one side of the cabinet 1, so that the maintenance tools stored in the top of the tool box 4 are close to the maintenance personnel, which is convenient for the maintenance personnel to quickly take and use them, thereby improving convenience. A cover plate 5 installed on one side of the tool box 4 is used to open and close the top of the tool box 4.

[0026] like Figure 2 As shown, a plurality of vertical grids 101 are provided for storing maintenance tools, a storage grid 102 is provided so that one end of the support assembly 3 can be mounted on the inner side thereof and the support assembly 3 can be folded in, and a handle 103 is provided for pulling the cabinet 1 to move.

[0027] like Figure 3 and Figure 5 As shown, by setting the support component 3 into three parts including a fixed plate 301, a support arm 302 and a hydraulic rod 303, the fixed plate 301 can be used to connect one end of the two support arms 302 to it and can rotate, and a No. 1 connecting shaft 3021 is provided at one end of the support arm 302 and connected to a No. 1 rotating hole 4021, so that the support arm 302 can support the connecting plate 402, and a hydraulic rod 303 is provided to support the connecting plate 402 to provide a supporting force, and a No. 2 connecting shaft 3031 is used to be rotatably connected to the No. 2 rotating hole 4022.

[0028] In practice, the support assembly 3 is installed on the inner side of the storage grid 102, and the tool box 4 is provided above the vertical grid 101, and the tool box 4 is movably connected to the cabinet 1 through the support assembly 3. Since the support assembly 3 is composed of a fixing plate 301, a support arm 302 and a hydraulic rod 303, when the tool box 4 is placed on the top of the cabinet 1, the tools inside the tool box 4 can be taken out normally, and after the tool box 4 is pulled, the support arm 302 can be rotated around the connection of the fixing plate 301, at this time, the first connecting shaft 3021 and the first rotating hole 402 are connected. 1 will also rotate, and the connection between the second connecting shaft 3031 and the second rotating hole 4022 will also rotate. The hydraulic rod 303 will generate a supporting force inside it due to the rotation to push the tool box 4, so that the tool box 4 as a whole is lifted and rotated from above the vertical grid 101, achieving the effect of displacement while lifting, and the interior of the vertical grid 101 can also facilitate the access to maintenance tools, so that the tool box 4 is raised in height and closer to the maintenance personnel, which is convenient for the maintenance personnel to use quickly and improves convenience.

[0029] Embodiment 2:

[0033] In practice, an instrument slot 401 is provided at the bottom of the tool box 4 and the connecting plate 402 is installed therein, and a locking bolt 4024 is provided to pass through the interior of the third rotating hole 4023 and then connect with the threaded hole 4012, so that the rotation of the tool box 4 can be controlled by the locking bolt 4024. When the outer thread teeth of one end of the locking bolt 4024 are connected to the inner side of the threaded hole 4012, the tool box 4 cannot rotate in any direction, and when the locking bolt 4024 is rotated so that its thread teeth are not connected to the interior of the threaded hole 4012, the tool box 4 can be rotated. , so that the tool box 4 is rotated in a specified direction with the locking bolt 4024 as the center, and the top direction of the tool box 4 is rotated to the side direction. At this time, the tools originally in the top of the tool box 4 can directly face the maintenance personnel, and by arranging a fixer 405 in the tool grid 404, the tools can be prevented from falling after the tool box 4 is rotated, so that all the tools in the tool box 4 are displayed in front of the maintenance personnel, making it convenient for them to take or put back at will, thereby avoiding the trouble of having to take the tools of the tool box 4 from the top, and improving the flexibility of use of the tool box 4.

[0034] The advantages of this technical solution in practical applications include but are not limited to the following:

[0035] 1. A rotating support structure is formed by providing a fixing plate 301, a support arm 302 and a hydraulic rod 303, so that the tool box 4 can be normally placed on the top of the cabinet 1, and by pushing the tool box 4, the connection points at both ends of the support arm 302 and the connection point between the hydraulic rod 303 and the connecting plate 402 are rotated, so that the support force generated by the hydraulic rod 303 pushes the tool box 4 to rotate, rise and move, which is convenient for maintenance personnel to take and use tools;

[0036] 2. By providing a locking bolt 4024 that is internally connected to the threaded hole 4012, and the locking bolt 4024 can rotate around the No. 3 rotating hole 4023, the tool box 4 can be controlled to rotate in a specified direction with this as the center, so that the tool grid 404 can be rotated from the top to the side, and the tool can be fixed by the fixer 405 to prevent it from falling, so that the tool grid 404 faces the maintenance personnel, which is convenient and quick to use and improves convenience.

[0037] The present technical scheme connects the tool box 4 with the cabinet 1 movably through the supporting assembly 3. When the tool box 4 is placed on the top of the cabinet 1, the tools inside it can be taken out normally, and after pulling the tool box 4, the supporting arm 302 can be rotated around the connection of the fixing plate 301, at this time, the connection between the No. 1 connecting shaft 3021 and the No. 1 rotating hole 4021 will also rotate, and the connection between the No. 2 connecting shaft 3031 and the No. 2 rotating hole 4022 will also rotate, then the hydraulic rod 303 will generate a supporting force inside it due to the rotation to push the tool box 4, so that the tool box 4 as a whole is lifted and rotated from the top of the vertical grid 101, achieving the effect of displacement while lifting, and the interior of the vertical grid 101 can also be convenient for taking out maintenance tools, so that the tool box 4 is raised in height and closer to the maintenance personnel, which is convenient for the maintenance personnel to use quickly and improves convenience, and then a locking bolt 4024 is provided through the No. 3 rotating hole The inside of hole 4023 can be connected with threaded hole 4012, so that locking bolt 4024 can control the rotation of tool box 4. When the outer thread teeth of one end of locking bolt 4024 are connected with the inner side of threaded hole 4012, tool box 4 cannot rotate. When locking bolt 4024 is turned so that its thread teeth are not connected with the inside of threaded hole 4012, tool box 4 can be rotated, so that tool box 4 can be rotated in a specified direction with locking bolt 4024 as the center, and the top direction of tool box 4 is rotated to the side direction. At this time, the tools originally in the top of tool box 4 can directly face the maintenance personnel, and by arranging a fixer 405 in the tool grid 404, the tools can be prevented from falling after the tool box 4 is rotated, so that all the tools in the tool box 4 are displayed in front of the maintenance personnel, which is convenient for them to take or put back at will, thereby avoiding the trouble of having to take the tools in tool box 4 from the top, thereby improving the flexibility of use of tool box 4.
