[0002] At the construction site of a petroleum liquefied gas pipeline, safety guardrails are used to ensure the safety of workers and passers-by on the site. Usually after a section of pipeline is completed, the guardrails around it need to be removed and transported to the surrounding area of ​​the pipeline under construction for protection.

[0003] When existing guardrails are used for protection at construction sites, the guardrails need to be connected and fixed by bolts. When the petroleum liquefied gas pipeline is under construction for a long time, the bolts may rust. The rusted bolts may affect the connection stability of the guardrail and the safety of the overall structure. It will also increase the difficulty of removing the guardrail, resulting in the problem of inconvenience in disassembling and assembling the guardrail. Utility Model Content

[0004] In view of the above problems existing in the prior art, the utility model provides a guardrail.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a guardrail, including a base plate, a fixing mechanism fixedly connected to the upper surface of the base plate, an installation mechanism slidably connected to the inner side of the fixing mechanism, the fixing mechanism including a fixing frame fixedly connected to the upper surface of the base plate, and a latch block slidably connected to the upper surface of the base plate, a groove is provided on the outer surface of the latch block, and the installation mechanism includes a clamping block slidably connected to the inner wall of the fixing frame, the outer surface of the clamping block is slidably connected to a connecting block, and the outer surface of the connecting block is slidably connected to the outer surface of the fixing frame.

[0007] By adopting the above technical solution, the sliding rod can be easily limited by the connecting block to prevent the sliding rod and the baffle from separating.

[0008] As a preferred solution of the guardrail of the utility model, the other end of the sliding rod is fixedly connected with a connecting plate, and the outer surface of the connecting plate is fixedly connected to the outer surface of the connecting block.

[0009] By adopting the above technical solution, the length of the baffle can be increased by pulling the connecting plate, thereby increasing the interception range of the baffle.

[0011] By adopting the above technical solution, the bidirectional threaded rod is rotated by turning the knob, so that the two groups of clamping blocks can move away from each other or move closer to each other.

[0012] As a preferred solution of the guardrail of the utility model, the lower surface of the knob is slidably connected to a sealing plate, the outer surface of the sealing plate is fixedly connected to the inner side surface of the fixed frame, and the upper surface of the fixed frame is provided with a through hole.

[0016] The utility model provides a guardrail having the following beneficial effects:

[0017] 1. Insert the connecting block at one end of the baffle into the inner wall of the fixed frame and turn the knob. The rotation of the knob drives the two-way threaded rod to rotate, so that the two sets of blocks are close to each other, which is convenient for assembling the guardrail. Turn the knob in the opposite direction to separate the outer surface of the block and the outer surface of the connecting block. Then pull the sliding rod to slide the connecting plate toward the baffle, so that the connecting block can be pulled out of the fixed frame, the baffle can be disassembled, and the guardrail can be assembled and disassembled.

[0018] 2. Use an external crowbar to insert one end of the crowbar into the groove on the outer surface of the latch block, then press the outer surface of the crowbar down to the upper surface of the fixed block, and use the fixed block as a fulcrum to press down, so as to facilitate the latch block to be tilted upward, causing the latch block to loosen, making it easier to pull the latch block out of the ground, and then facilitate the position of the base plate.
