Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4, including fixed plate 1, 1 lower extreme of fixed plate is through a plurality of fixed columns 2 and ground fixed connection, the fixed plate 1 left and right sides is equipped with two T shaped plates 3 that can control about moving respectively, T shaped plate 3 articulates through axial pivot 13 from top to bottom has fore-and-aft direction's commentaries on classics board 4, it is relative and splayed about two commentaries on classics board 4, two commentaries on classics board 4 front ends rotate respectively and are connected with axial round pin axle 14 from top to bottom, two round pin axle 14 downside articulate has a guard box 5, be equipped with a plurality of upper and lower axial in the guard box 5 and along the hollow tube 6 of left and right directions equipartition, 6 outer fringe faces of hollow tube and 5 inside wall contacts of guard box, guard box 5 rear end is equipped with one-level spring 9 with 1 front end fixed connection of fixed plate, guard box 5 front end is equipped with elastic plate 7.

In order to enable the T-shaped plate 3 to move left and right, the left side and the right side of the fixed plate 1 are respectively provided with a T-shaped groove 8 with a forward opening and a left-right direction, and the T-shaped plate 3 is connected with the T-shaped groove 8 on the corresponding side in a sliding manner.

In order to enhance the buffer force of the device, the opposite ends of the two T-shaped plates 3 are respectively provided with a secondary spring 15 which is axially arranged at the left and the right and is fixedly connected with the T-shaped groove 8 at the corresponding side.

In order to reduce the maintenance of the device and increase the stability of the device, a plurality of trapezoidal plates 10 with small top and large bottom are arranged below the protective box 5, the upper end surface of each trapezoidal plate 10 is in contact with the protective box 5, and the lower end of each trapezoidal plate is fixedly connected with the ground.

In order to increase the visibility of the elastic plate 7 at night, the front end face of the elastic plate 7 is provided with a light reflecting coating 11.

In order to prevent the rotating shaft 13 from being pricked into the automobile after being crashed, the upper end and the lower end of the rotating shaft 13 and the upper end and the lower end of the pin shaft 14 are respectively provided with a rubber sleeve 12.

When the utility model is used, when the automobile contacts the elastic plate 7, the elastic plate 7 deforms and blocks the automobile from moving backwards, thus forming a first-level buffer to the automobile;

if the automobile can not stop after the first-stage buffering, the automobile continues to move backwards, the automobile extrudes the protective box 5 backwards through the elastic plate 7, the protective box 5 pushes the two rotating plates 4 to swing relatively and compress the first-stage spring 9, at the moment, the left T-shaped plate 3 moves rightwards relative to the left T-shaped groove 8, the right T-shaped plate 3 moves leftwards relative to the right T-shaped groove 8, the second-stage spring 15 is compressed, in the process that the protective box 5 pushes the two rotating plates 4 to swing relatively, the first-stage spring 9 blocks the anti-sliding plates from moving backwards, and the second-stage spring 15 blocks the two T-shaped plates 3 from moving relatively, so that the second-stage buffering for the automobile is formed;

if the automobile still can not stop after the secondary buffering, the automobile continues to move backwards, when the secondary spring 15 is compressed to the limit, the primary spring 9 is compressed to the limit, the automobile backward extrudes the protective box 5 along with the backward movement of the automobile, the protective box 5 deforms and extrudes the hollow pipe 6, the hollow pipe 6 deforms, the internal gap of the hollow pipe 6 is gradually small, and the hollow pipe 6 changes and simultaneously blocks the automobile from continuing to move backwards until the automobile stops moving.

The utility model discloses in set up reflective coating 11, be to avoid the car because of night visibility reduces, can't see protective housing 5 and hit the phenomenon to protective housing 5.
