DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 A shock absorbing coordination device shown in the figure comprises a bottom connecting plate 1, a shock absorbing layer 2 and an upper connecting plate 3, the bottom connecting plate 1, the shock absorbing layer 2 and the upper connecting plate 3 constitute a rubber shock absorbing bracket, U-shaped recesses 4 are provided on both sides of the upper end of the upper connecting plate 3, a clamping plate 5 is provided between two adjacent upper connecting plates 3, both ends of the clamping plate 5 are fixedly connected with a connecting rod 6, the connecting rod 6 is located in the U-shaped recess 4 and is fixedly connected with a clamping rod 16, the bottom side of the clamping rod 16 is movably inserted into a limiting groove 15 and the limiting groove 15 is located in the U-shaped recess 4, the adaptability of the connecting rod 6 is improved by setting a diameter longer than the diameter of the clamping rod 16, and the clamping rod 16 is provided to improve the adaptability of the connecting rod 6. A support rod 7 is fixedly connected to the bottom end of the plate 5, a piston 19 is fixedly connected to the bottom end of the support rod 7, a fixed column 8 is arranged on the bottom side of the support rod 7, a buffer cylinder 9 is opened in the fixed column 8, through holes 18 are evenly opened on the bottom side of the buffer cylinder 9, the buffer cylinder 9 is located on the upper side of the through hole 18 and is fixedly connected to a limit ring 10, an air hole is opened at the fixed column 8 at the through hole 18, and a pad 11 is fixedly connected to the bottom end of the buffer cylinder 9. When the card plate 5 is forced to move downward, the support rod 7 moves downward synchronously, so that the piston 19 squeezes the air inside the buffer cylinder 9, and the air overflows from the through hole 18 to provide resistance, thereby achieving an auxiliary buffering effect.

[0018] Among them, a limiting rod 12 is set between two adjacent bottom connecting plates 1, and the limiting rod 12 is inserted into four sides of the pad 11 that are far away from each other. By setting the limiting rod 12 to connect the road bridge body, the stability of the fixing column 8 can be improved.

[0019] The upper side of the bottom connecting plate 1 contacts the ball 13 , and the ball 13 is rotatably embedded in the four sides of the bottom end of the pad 11 . The friction between the bottom connecting plate 1 and the pad 11 is reduced by providing the ball 13 .

[0020] The two sides of the fixing column 8 are fixedly connected to the triangular plates 14 , and the triangular plates 14 are fixedly connected to the two sides of the upper end of the pad 11 .

[0022] Working principle: When a single shock-absorbing support is subjected to force, it will contact a single upper connecting plate 3. At this time, the force through the card plate 5 and the connecting rod 6 will make the two adjacent upper connecting plates 3 consistent, thereby providing consistency in shock absorption and reducing the wear of the single shock-absorbing support. At the same time, when the card plate 5 is subjected to force, the support rod 7 and the piston 19 will squeeze the air in the buffer cylinder 9 downward, and the air will overflow from the through hole 18. At the same time, the buffer spring 17 is located between the card plate 5 and the fixed column 8, which can provide further buffering effect, thereby enhancing the shock absorption effect of the rubber shock-absorbing bracket while reducing the wear of the shock-absorbing bracket.
