[0026] Specifically, the bumper can be installed on the car through the mounting plate 1, and the mounting plate 1 has a fixing effect on the first pressure block 2. The telescopic rod 3 can ensure the buffer distance and connection support between the anti-collision plate 12 and the mounting plate 1. At the same time, when a collision occurs, the anti-collision plate 12 will squeeze the cylinder 5 in the frame 4 through the second pressure block 6, and the first pressure block 2 will also squeeze into the cylinder 5 to provide a buffer for its collision. At the same time, the second support plate 13 can disperse the pressure exerted on the anti-collision plate 12 to the two ends of the frame 4 through the second connecting plate 14, and the first connecting plate 9 rotating on the inner wall of the first support plate 8 cooperates with the second connecting plate 14 to push the guide blocks 10 at both ends of the frame 4 to move outward on the inner wall of the fixing frame 7, and the pressure caused by the collision and squeezing is buffered by the spring 11, thereby achieving a better shock absorption effect.

[0027] Reference Figure 3 A slot 15 is provided inside the anti-collision plate 12, and a shell 16 is provided on the outer wall of the anti-collision plate 12. A screw 17 is connected to the inner thread of the shell 16; and a fixed sleeve 22 is fixedly connected to the outer wall of the shell 16;

[0028] Specifically, the anti-collision plate 12 can support the position of the outer shell 16 , and the screw column 17 can rotate inside the outer shell 16 , and the outer shell 16 has a fixed supporting function for the fixed sleeve 22 .

[0029] Reference Figure 3-Figure 4 One end of the threaded column 17 is fixedly connected to a turning handle 18, and the other end of the threaded column 17 is fixedly connected to a pushing block 19; the outer wall of the pushing block 19 is fixedly connected to a limiting column 20, and a locking ball 21 is arranged on the outer wall of the pushing block 19; the outer wall of the limiting column 20 is provided with a locking ball 21, and the outer wall of the locking ball 21 is slidably connected to the inner wall of the fixed sleeve 22; the outer wall of the fixed sleeve 22 is arranged on the inner wall of the slot 15, and the outer wall of the locking ball 21 is arranged on the inner wall of the slot 15;

[0030] Specifically, rotating the handle 18 can drive the screw column 17 to rotate, and the screw column 17 can fix the push block 19, and then drive the push block 19 to move on the inner wall of the fixed sleeve 22. The push block 19 has a fixed support function for the limiting column 20, and the push block 19 can push the locking ball 21 to extend out of the inner wall of the fixed sleeve 22. The limiting column 20 can ensure that the locking ball 21 will not fall off from the circular groove opened on the inner wall of the fixed sleeve 22. The outer wall of the fixed sleeve 22 can be inserted into the inner wall of the slot 15. At the same time, the housing 16 can be installed and fixed through the locking ball 21.

[0031] Working principle: When in use, technicians can install it on the car where it needs to be used through the mounting plate 1. When the car's outer shell 16 is squeezed or collided, the telescopic rod 3 can provide a good buffer space for the squeezing. The anti-collision plate 12 will squeeze the cylinder 5 in the frame 4 through the second pressure block 6, and the first pressure block 2 will also squeeze into the cylinder 5 to provide a buffer for its collision. At the same time, the second support plate 13 can disperse the pressure exerted on the anti-collision plate 12 to the two ends of the frame 4 through the second connecting plate 14, and the first connecting plate 9 and the second connecting plate 14 rotating on the inner wall of the first support plate 8 can cooperate with each other to push the guide blocks 10 at both ends of the frame 4 to move outward on the inner wall of the fixing frame 7, and the spring 11 is used to buffer the pressure caused by the collision and squeezing, thereby achieving a better shock absorbing effect. When the outer shell 16 needs to be disassembled or replaced, the technician can rotate the four turning handles 18 to drive the screw column 17 to rotate inside the outer shell 16, so that the push block 19 can move on the inner wall of the fixed sleeve 22. When the screw column 17 moves inwardly through the threaded connection, the inclined surface of the push block 19 can squeeze the positioning ball 21 until half of the positioning ball 21 extends out of the inner wall of the fixing sleeve 22, so that the positioning ball 21 can be stuck in the inner wall of the slot 15, and then the shell 16 can be installed. When the handle 18 drives the screw column 17 to move outward, the shell 16 is pulled outward, and the positioning ball 21 will shrink to the inner wall of the fixing sleeve 22 in the slot 15. The limiting column 20 can prevent the positioning ball 21 from falling off from the circular groove of the fixing sleeve 22, and then the shell 16 can be disassembled, which is convenient for maintenance personnel to inspect and repair the inside of the bumper. That is, the device can not only disperse the excessive pressure generated by the collision and extrusion to both ends, but also effectively buffer and absorb the impact pressure and improve the shock absorption efficiency. At the same time, the shell 16 can be disassembled and replaced, which can extend the life of the overall bumper and reduce the replacement cost caused by damage or corrosion of the shell 16. At the same time, it is convenient for maintenance personnel to inspect and diagnose problems with the bumper and improve the efficiency of repair.
