The utility model provides a pair of structure of bumper shock absorber is as shown in figure 1 picture 2 and figure 3, including five metals pipe 1 and screw rod 2, one side of five metals pipe 1 has been seted up and has been run through groove 11, the diameter that runs through groove 11 is greater than the diameter of arc dog 21 place circle, and the inside that runs through groove 11 runs through there is screw rod 2, the surface of screw rod 2 is provided with two sets of arc dog 21 respectively, and arrange from top to bottom two sets of arc dog 21, the surface cover of screw rod 2 is equipped with spring 3, and spring 3 is located the inside of five metals pipe 1 or is located the below of five metals pipe 1, when spring 3 is located the inside of five metals pipe 1, this spring 3 mutually supports with the arc dog 21 that is located screw rod 2 top, be used for stopping spring 3.

Further, as shown in fig. 4, 5 and 6, when the spring 3 is located below the hardware pipe 1, the spring 3 is matched with the arc-shaped stop 21 located below the screw rod 2 for stopping the spring 3.

During the implementation, place spring 3 in the inside or the below of five metals pipe 1, pass through groove 11 with screw rod 2 afterwards, arc dog 21 through screw rod 2 surface, make spring 3 and screw rod 2 slide each other can not take place, promptly when screw rod 2 atress, spring 3 can be compressed, consequently when inside or the below of five metals pipe 1 has increased a spring 3, it can play absorbing effect under the special circumstances, can increase the life-span of screw rod 2, bearing capacity also can promote, when the atress of the top, screw rod 2 can move down, can make spring 3 produce deformation, bear a part of component.

Further, as shown in fig. 7, a clamping assembly 4 is arranged inside the through groove 11, the clamping assembly 4 is composed of arc-shaped sheets 41, clamping springs 42 and protection sheets 43, three groups of arc-shaped sheets 41 are arranged inside the through groove 11, an included angle between every two adjacent arc-shaped sheets 41 is one hundred twenty degrees, the protection sheets 43 are fixed on the surfaces of the arc-shaped sheets 41, the surfaces of the protection sheets 43 and the surfaces of the screws 2 are attached to each other, the clamping springs 42 are fixed at equal intervals at one end of each arc-shaped sheet 41, and the other ends of the clamping springs 42 are fixedly connected with the inner wall of the through groove 11.

In implementation, the protection sheet 43 on the surface of the arc-shaped sheet 41 is pushed to be attached to the screw 2 by the elastic force of the clamping spring 42, so that the resistance of downward movement of the screw 2 when being stressed is increased.

The working principle is as follows: during the use, at first place spring 3 in the inside or below of five metals pipe 1, pass through groove 11 with screw rod 2 afterwards, carry out the centre gripping through centre gripping subassembly 4 when passing, when centre gripping subassembly 4 was implemented, the protection piece 43 that promotes arc piece 41 surface through the spring action of clamping spring 42 was laminated with screw rod 2, increased the resistance that moves down when screw rod 2 atress.

Simultaneously at the arc dog 21 on screw rod 2 surface, make spring 3 and screw rod 2 can not take place to slide each other, promptly when the atress of screw rod 2, spring 3 can be compressed, consequently when the inside of five metals pipe 1 or below has increased a spring 3, it can play absorbing effect under the special circumstances, can increase the life-span of screw rod 2, bearing capacity also can promote, when the atress of the top, screw rod 2 can down move, can make spring 3 produce deformation, bear a part of component, finally accomplish the use work of bumper shock absorber.
