Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of multi-functional afterbody safety protective for lorry
Column, including preceding guardrail 1, rear guardrail 2, lower baffle plate 3, hound 4, sliding shoe 5, buffering energy-absorbing spring 6, connecting rod 7 and sliding groove
Mouthfuls 8, preceding guardrail 1 is made up of two girders and two vertical rods, and rear guardrail 2 is made up of two girders and two vertical rods, preceding guardrail 1 with
Buffering energy-absorbing spring 6,1 two girders of preceding guardrail or so two ends are provided between guardrail 2 afterwards and are provided with sliding shoe 5, rear guardrail 2
Two girders or so two ends offer the slip notch 8 being engaged with sliding shoe 5, the company of being provided with 2 two girders of rear guardrail
Extension bar 7 is connected with truck chassis, and the lower section of preceding guardrail 1 is provided with lower baffle plate 3, and hound is passed through between lower baffle plate 3 and rear guardrail 2
4 are connected.
In above-described embodiment, specifically, when the distance between preceding guardrail 1 and rear guardrail 2 relax less than buffering energy-absorbing spring 6
Length, the moment of buffering energy-absorbing spring 6 is in compressive state, give two guardrail support forces, strengthen the crashworthiness of guardrail；
