[0025] As Figure 1 , Figure 2 and Figure 3 shown, compression springs 8 are sleeved on both groups of insertion rods 7, stoppers 9 are fixedly sleeved on both groups of insertion rods 7, the two groups of insertion rods 7 are respectively slidably connected to the box body 1 through the stoppers 9, and both ends of the compression spring 8 are fixedly connected to the stopper 9 and the box body 1 respectively. The handle 11 penetrates through the box body 1 and is rotatably connected to the box body 1. A gear 12 is sleeved on the handle 11. The gear 12 is located between the two racks 10. The gear 12 is meshed with the two racks 10 respectively. A torsion spring 13 is sleeved on the handle 11.

[0026] The quick disassembly and assembly of the box body 1 and the box cover 2 are realized through the cooperation of the arranged insertion rods 7 and the insertion plate 4, and then the fixation of the battery by the box body 1 is cooperated, so that the whole distribution box can realize the quick disassembly and assembly between parts, effectively improving the working efficiency; when disassembling the box cover 2, rotate the handle 11 to drive the gear 12 to rotate. The gear 12 is meshed with the two racks 10. As the gear 12 rotates, the two racks 10 slide outwards synchronously, and drive the fixed frame 6 and the insertion rods 7 on the fixed frame 6 to slide outwards synchronously, disengaging from the clamping connection with the insertion plate 4, so that the box cover 2 and the insertion plate 4 can be quickly separated from the box body 1, completing the disassembly of the box cover 2 and the box body 1. When installing the box cover 2, insert the insertion plate 4 into the slot 5. Under the action of the compression spring 8 and the torsion spring 13, the two fixed frames 6 and the insertion rods 7 automatically move inwards and are clamped with the insertion plate 4, completing the installation and fixation between the box cover 2 and the box body 1.

[0027] The utility model provides a hydrogen fuel cell distribution box which is convenient for disassembly and assembly. The specific working principle is as follows: The rotation of the bidirectional lead screw 16 is driven by a motor. Under the action of the synchronous pulley 17 and the synchronous belt 18, the two groups of bidirectional lead screws 16 rotate synchronously. Under the limiting action of the box body 1 and the mounting plate 3, the distance between the two groups of sliders 15 is adjusted, so as to adjust the inclination angle of the two groups of brackets 14 and the height of the mounting plate 3, which is convenient for the staff to disassemble and assemble the battery in the box body 1 with a relatively deep depth. At the same time, the two motors cooperate with the transmission belt 25 and the transmission wheel 24 to drive the two groups of first bidirectional screws 22 and the second bidirectional screws 23 to rotate simultaneously. Under the limiting action of the mounting plate 3, the distance between the four groups of clamping blocks 19 is adjusted, so as to fix the center position of different models of batteries on the mounting plate 3. The movement between the four groups of clamping blocks 19 is fast, and the fixing and disassembly in the battery box body 1 can be done quickly and conveniently. Moreover, since the position of the mounting plate 3 and the distance between the four groups of clamping blocks 19 can be adjusted, it is convenient to install different models of batteries in this distribution box. When disassembling the box cover 2, rotate the handle 11 to drive the gear 12 to rotate. The gear 12 is meshed and connected with the two groups of racks 10. As the gear 12 rotates, the two groups of racks 10 slide out synchronously, and drive the fixing frame 6 and the insertion rod 7 on the fixing frame 6 to slide out synchronously, disengaging from the clamping connection with the insertion plate 4. Thus, both the box cover 2 and the insertion plate 4 can be quickly separated from the box body 1, completing the disassembly of the box cover 2 and the box body 1. When installing the box cover 2, insert the insertion plate 4 into the slot 5. Under the action of the compression spring 8 and the torsion spring 13, the two groups of fixing frames 6 and the insertion rod 7 automatically move inward and are clamped with the insertion plate 4, completing the installation and fixing between the box cover 2 and the box body 1.
