each group of anti-collision rod pieces comprises a cross rod detachably connected between two vertical rods, the outer edge surface of each cross rod is coaxially and fixedly connected with a plurality of baffle discs uniformly distributed along the length direction of the cross rod, opposite ends of any two adjacent baffle discs are fixedly connected with springs, the springs are coaxially sleeved on the outer side of the cross rod, an anti-collision sleeve is coaxially sleeved on the outer side of the cross rod, and the inner wall of the anti-collision sleeve is fixedly connected with the outer edge surface of each baffle disc;

the left end and the right end of each cross rod are respectively and fixedly connected with a butt flange coaxially, and the two upright posts are respectively and fixedly connected with fastening components which correspond to the butt flanges one to one.

Preferably, each fastening assembly comprises a connecting sleeve fixedly connected with the vertical rod, first flanges corresponding to the butt flanges are fixedly connected to the outer edge surfaces of the connecting sleeves, and the first flanges correspond to the butt flanges one to one and are detachably connected through bolts.

Preferably, a second flange symmetrically arranged with the first flange is fixedly connected to the outer edge surface of each connecting sleeve.

Preferably, the lower end of each vertical rod is fixedly connected with a supporting seat, and four connecting holes uniformly distributed around the axis of each supporting seat are formed in each supporting seat.

The utility model has the advantages that:

the utility model discloses the inherent a plurality of fender dishes of its length direction equipartition of edge of anticollision member outside cover that in be equipped with, and the equal fixedly connected with suit of looks remote site of arbitrary two adjacent fender dishes is at the spring in the horizontal pole outside on the horizontal pole, keep off the crashproof cover that outer fringe face fixedly connected with and horizontal pole coaxial arranged in addition, when the occurence of failure, crashproof cover receives the impact of car earlier, space between crashproof cover and the horizontal pole provides deformation space for crashproof cover, the impact that causes the car carries out the buffering energy dissipation of certain degree, when assaulting great effect and horizontal pole, the spring with the fixed connection of separation blade in the horizontal pole outside will produce elastic deformation prior to the horizontal pole, cushion the energy dissipation to the impact. In addition, under the protection of the spring, the cross rod is not easy to break, and the risk of casualties caused by the fact that the cross rod is broken and inserted into a vehicle body is reduced.

Reference numerals

1. The device comprises a vertical rod, a cross rod, a baffle disc, a spring, a collision-proof sleeve, a butt flange, a connecting sleeve, a bolt, a second flange, a supporting seat and a connecting hole, wherein the cross rod is 2, the baffle disc is 3, the spring is 4, the collision-proof sleeve is 5, the butt flange is 6, the connecting sleeve is 7, the first flange is 8, the bolt is 9, the second flange is 10, the supporting seat is 11, and the connecting hole is 12.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings 1-7.

Embodiment one, the technical scheme of its solution is, the utility model discloses the inherent a plurality of fender dish 3 along its length direction equipartition of crashproof member outside cover that are equipped with in, and the equal fixedly connected with suit of the looks remote site of arbitrary double-phase adjacent fender dish 3 on the horizontal pole 2 springs 4 in the horizontal pole 2 outsides, 3 outer fringe face fixedly connected with of fender dish in addition and 2 coaxial crashproof covers 5 of arranging of horizontal pole, when the occurence of failure, crashproof cover 5 receives the impact of car earlier, space between crashproof cover 5 and the horizontal pole 2 provides deformation space for crashproof cover 5, the impact that causes the car carries out the buffering energy dissipation of certain degree, when assaulting great effect and horizontal pole 2, the spring 4 of the fixed connection with the separation blade in the horizontal pole 2 outsides will produce elastic deformation earlier than horizontal pole 2, cushion the energy dissipation to assaulting. In addition, under the protection of the spring 4, the cross rod 2 is not easy to break, and the risk of casualties caused by the fact that the cross rod 2 is broken and inserted into a vehicle body is reduced.
