Height-adjustable spliced municipal engineering protective guard

Abstract

The invention discloses a height-adjustable spliced municipal engineering protective guard which comprises a first protective plate and a second protective plate, the first protective plate and the second protective plate are each provided with a plurality of storage grooves, a moving block is slidably installed in each storage groove, and an extrusion spring is fixedly installed between each moving block and the inner wall of the corresponding storage groove; and a positioning plate is fixedly installed on each moving block, a positioning hole is formed in each positioning plate, fixing drill rods are placed in the two positioning holes located in the side, and a positioning mechanism is installed between each moving block and the corresponding first protection plate or the corresponding second protection plate. The guard has the advantages that the guard is composed of a plurality of same protective plates with small sizes, every two protective plates can be quickly and fixedly spliced and disassembled, the guard is convenient and easy to assemble and disassemble, and the height can be adjusted, so that the protective height range can be adjusted according to the actual use condition.

Description

technical field [0001] The invention relates to the technical field of municipal engineering protective fences, in particular to a height-adjustable spliced ​​municipal engineering protective fence. Background technique [0002] Municipal engineering refers to various buildings, structures and other projects that are planned and constructed by the government in urban areas and towns. During construction of municipal engineering, it is usually necessary to set up protective fences outside the construction site to prevent citizens from entering the construction area. the possibility of potential safety hazards; [0003] The existing municipal engineering guardrails still have the following deficiencies in use: [0004] 1. The existing guardrails are usually composed of multiple sets of guard plates. When installing, multiple bolts and nuts are used to connect the guard plates together, and the overall operation is troublesome; [0005] 2. The protective plates in the existin...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing guardrails are usually composed of multiple sets of guard plates. When installing, multiple bolts and nuts are used to connect the guard plates together, and the overall operation is troublesome;

[0005] 2. The protective plates in the existing protective fence are generally formed in one piece, and the overall volume is large, which cannot be disassembled, and it is more troublesome to transport and transfer;

[0006] 3. The height of the existing guardrail is relatively fixed, and it is impossible to increase the height of the guardrail according to the actual use situation, which has certain limitations
