Through adopting above-mentioned technical scheme, the setting of antiskid line can increase the frictional force of hand and push rod, prevents to take place phenomenons such as skid, makes the operation process more stable.

Furthermore, the upper end edge of the upright post is in arc transition.

Through adopting above-mentioned technical scheme, the fillet that stand upper end edge had makes the stand upper end more level and smooth, has reduced the possibility that causes secondary damage in the installation or after the occurence of failure.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the clamping end is clamped with the clamping groove, so that the stability and the safety of the guardrail can be improved;

(2) by arranging the guide surface, the insertion end and the clamping groove can be positioned more easily, so that the installation process is more convenient and faster;

(3) through setting up spigot surface and inclined plane, can make the location of joint end and draw-in groove quicker to accelerate the installation rate, make the operation convenient and fast more.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A traffic safety guardrail is shown in figure 1 and comprises a guardrail body 1 which is composed of a barrier 2 and upright posts 3 positioned at two sides of the barrier 2.

As shown in fig. 1, the upper end edge of the upright post 3 is in arc transition. The fillet that 3 upper end edges of stand had makes 3 upper ends of stand smoother, has reduced the possibility that causes secondary damage in the installation after injury or the occurence of failure.

As shown in fig. 2 and 3, the top and the bottom of the upright post 3 are all provided with a clamping groove 4 in a penetrating manner, the two ends of the barrier 2 are extended to form a clamping end 21 extending into the clamping groove 4, at least one slot 5 is arranged in the clamping groove 4, the lower end face of the clamping end 21 is extended to form an inserting end 7 embedded with the slot 5, the upright post 3 is rotatably connected with a pressing cover plate 6 abutting against the upper end face of the clamping end 21, and the pressing cover plate 6 is in an L shape and abuts against the upper end face of the L-shaped bottom end and the clamping end 21.
