Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in fig. 1-6, an easy-to-fold road construction guardrail comprises a guardrail body 1, wherein the guardrail body 1 is a part of a construction guardrail on the market except two support legs at the bottom; the bottom of the guardrail body 1 is also connected with two supporting pieces 2, and the supporting pieces 2 are square metal blocks; the left side and the right side of the lower end part of the guardrail body 1 are respectively provided with a strip-shaped groove 11, the groove 11 is formed by upwards sinking from the lower end of the guardrail body, a clamping piece 4 is arranged in the groove 11, one end of the clamping piece 4 is fixed, and the other end of the clamping piece 4 can horizontally move along the fixed end; the clamping piece 4 is a U-shaped groove, and the opening direction of the U-shaped groove is transversely arranged; a metal strip is fixed on the end part of the clamping and fixing piece 4, so that a clamping and fixing opening 41 is formed on the clamping and fixing piece 4, a rolling piece 7 is sleeved on the metal strip, and the rolling piece 7 is a metal pipe; meanwhile, a fixing piece 3 matched with the clamping piece 4 is arranged in the groove 11, the fixing piece 3 is made of wear-resistant plastics, and the fixing piece 3 can move back and forth along the groove 11; a fixing hook 31 is provided on an end portion of the fixing member 3, and the fixing hook 31 and the fixing member 3 are integrally formed; when in use, the fixing hook 31 is hooked into the clamping and fixing port 41; meanwhile, a connecting rod 8 is movably connected to the support member 2, and the connecting rod 8 is a metal rod; the other end of the connecting rod 8 is movably connected with the fixed part 3; therefore, when the support 2 is used, the fixing member 3 moves forward along the groove 11, and then the fixing hook 31 is hooked into the fastening opening 41, so that the support 2 is fixed.
