[0023] Example 1: Please refer to Figure 1 - Figure 3A turbine maintenance box includes a box body 1 and casters 2 fixedly installed at the four corners of the lower end of the box body 1. Handrails 11 are fixedly installed on both sides of the side wall of the box body 1. A movable cover 12 is rotatably installed on the upper end of the box body 1. Springs 16 are fixedly installed at the four corners of the lower end of the inner wall of the box body 1. Each spring 16 has a telescopic rod 17 installed inside. The upper ends of the springs 16 and the telescopic rods 17 are fixedly installed with a lower storage compartment 15. The lower storage compartment 15 is slidably connected to the inner wall of the box body 1. A sliding groove 18 is opened on the side of the box body 1. An upper storage compartment 13 is slidably connected in the sliding groove 18. A pull ring 131 is fixedly installed on the side wall of the upper storage compartment 13.

[0024] In this embodiment: when the tools in the machine maintenance box are needed, first open the movable cover 12, and pull the upper storage compartment 13 outward along the slide groove 18 through the pull ring 131. At this time, the upper storage compartment 13 slides away from the upper end of the lower storage compartment 15 along the slide groove 18. Under the action of multiple springs 16, the lower storage compartment 15 is automatically pushed upward. The springs 16 can push the lower storage compartment 15 upward along the inner wall of the box body 1 until the upper end of the lower storage compartment 15 is flush with the upper storage compartment 13. At this time, the two tool storage compartments are opened at the same time. After the upper storage compartment 13 is opened, the lower storage compartment 15 can automatically slide outward to be flush with it, which facilitates the retrieval of materials and tools in the two storage compartments.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 5 A slot 14 is provided between the two side walls of the box body 1 and the upper storage compartment 13. A connecting rod 141 is fixedly installed between the upper and lower inner walls of the slot 14. The connecting rod 141 can be used to connect the movable rod 31 and the movable rod 32.

[0026] A support assembly 3 is installed between two adjacent connecting rods 141. The support assembly 3 includes a movable rod 31 rotatably mounted on the upper connecting rod 141 and a movable rod 32 rotatably mounted on the lower connecting rod 141. Both the movable rod 31 and the movable rod 32 are located inside the slot 14.

[0027] Movable rod 1 31 and movable rod 2 32 are slidably connected. A spring 2 33 is fixedly installed between the inner walls of movable rod 1 31 and movable rod 2 32. The spring 2 33 ensures a tight connection between movable rod 1 31 and movable rod 2 32.

[0028] Both sides of the lower storage compartment 15 are provided with movable slots 151, and movable blocks 152 are slidably connected in each movable slot 151.

[0029] A spring 153 is fixedly installed between the inner wall of the movable block 152 and the side wall of the movable groove 151. When the movable block 152 moves, it is slidably connected in the slide groove 18. When the movable block 152 slides to be directly opposite the slide groove 18, it can automatically push outward to limit the lower storage compartment 15.

[0030] In this embodiment: when the tools inside the device are needed, the upper storage compartment 13 can be pulled outwards using the pull ring 131. As the upper storage compartment 13 slides outwards along the slide groove 18, it drives the movable rod 31 in the slot 14 to rotate along the connecting rod 141. At the same time, the rotation of the movable rod 31 drives the lower movable rod 32 to rotate along the lower connecting rod 141. During the outward sliding process of the upper storage compartment 13, the distance between the inner walls of the movable rod 31 and the movable rod 32 increases. Under the action of the spring 33, the two are stretched and tightly connected. The spring 33 provides support to the upper storage compartment 13. The oblique support force prevents uneven force on the movable end of the upper storage compartment 13 from causing deflection. After the upper storage compartment 13 is fully pulled out, the lower storage compartment 15 is automatically pushed upward under the action of spring 16. When the movable block 152 is aligned with the slide groove 18, the movable block 152 is automatically pushed outward under the action of spring 3 153 and fixed in the slide groove 18, thus limiting the lower storage compartment 15. After the upper storage compartment 13 is pulled out, the device can also provide support on both sides to prevent uneven force from damaging the connection of the box body 1. The movable block 152 can automatically limit the movement of the lower storage compartment 15.
