Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

Referring to fig. 1-5, the utility model relates to an assembled type frontier defense guardrail, which comprises two symmetrically arranged upright posts 1, a guardrail is arranged between the two upright posts 1, the guardrail comprises two symmetrically arranged cross rods 2 and a plurality of upright rods 3 connecting the two cross rods 2;

the two ends of the cross rod 2 are provided with inserting ports, the upright post 1 is provided with inserting posts 106 matched with the inserting ports, the side surfaces of the inserting posts 106 are symmetrically provided with blind holes 107, springs 108 are fixedly arranged in the blind holes 107, the other ends of the springs 107 are provided with limiting heads 109, and the inner wall of the inserting ports is provided with limiting through holes matched with the limiting heads 109;

the lower end of the upright post 1 is provided with a rectangular opening 101, sliding grooves 105 are symmetrically arranged on two inner walls of the rectangular opening 101, a sliding rod 401 is arranged in the rectangular opening 101 in a sliding manner, wheels 4 are arranged at the lower end of the sliding rod 401, guide wheels 402 are symmetrically arranged on the side walls of the sliding rod 401, the guide wheels 402 are arranged in the sliding grooves 105 in a sliding manner, and both the sliding rod 401 and the guide wheels 4 can be arranged in the rectangular opening 101;

the sliding rod 401 is provided with a mounting hole 403, the other two inner walls of the rectangular opening 101 are provided with a plurality of through holes 102 matched with the mounting hole 403, and the sliding rod 401 is arranged on the upright post 1 through bolt connection.
