Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, in particular to a dense-mesh safety net with a quick-installation structure. Background Art

[0002] Close-mesh safety nets are usually used in construction projects to provide safety protection at construction sites. They effectively prevent various objects from falling freely and act as a buffer. The main function of close-mesh safety nets is to be combined with safety helmets to provide safety protection for construction sites. In construction sites where safety nets are installed, safety helmets must be worn when entering. The quality of the net is proportional to its density. The higher the density and the lower the transparency, the better the quality of the net and the higher the safety.

[0003] However, in actual use of the above equipment, a close-mesh safety net needs to be installed on the outside of the guardrail for isolation. The size of the foundation pit is different, and the circumference of the guardrail is also different, which results in the close-mesh safety nets needing to be connected in pairs for use. The two parts of the close-mesh safety net need to be connected by wire or clamps. This connection method requires that if one of the close-mesh safety nets is damaged, the entire part needs to be replaced. In addition, it is relatively troublesome to disassemble the close-mesh safety net, and a series of tedious steps are also required when installing the close-mesh safety net. In view of this, we propose a close-mesh safety net with a quick installation structure. Summary of the invention

[0004] The purpose of the utility model is to provide a close-mesh safety net with a quick installation structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a close-mesh safety net with a quick installation structure, comprising a safety net body, a side wall of the safety net body is provided with a connecting assembly, and the connecting assembly includes:

[0006] A fixed half-clip, the side wall of the safety net body is sleeved with a connecting piece, the connecting piece is fixedly connected to the fixed half-clip, the inner wall of the fixed half-clip is fixedly connected with a rubber arc plate, the end of the fixed half-clip away from the connecting piece is provided with a sliding groove, and the inner top of the sliding groove is provided with a limiting groove;

[0008] A movable half-clamp, wherein the end of the fixed half-clamp away from the connecting piece is hinged with the movable half-clamp, and the end of the movable half-clamp close to the fixed half-clamp is fixedly connected with a limiting tooth, and the limiting tooth cooperates with the end face of the fixed half-clamp;

[0009] A fixed rod, the movable half clamp is sleeved with the fixed rod, a side wall of the fixed rod is fixedly connected to a limiting block, and an end of the limiting block away from the fixed half clamp is fixedly connected to a clamping block;

[0010] The flexible arc plate, the movable half clamp is threadedly connected with a threaded rod, one end of the threaded rod is sleeved with the flexible arc plate, and the end of the threaded rod away from the flexible arc plate is fixedly connected with a knob 2.

[0011] Preferably, a groove is formed on the end surface of the flexible arc plate, and a groove is formed on the end surface of the rubber arc plate.

[0012] Preferably, the limiting block is slidably connected to the limiting groove, and the clamping block is clamped with the sliding groove, so that the fixed half clamp and the movable half clamp can be fixed together.

By fixing the safety net on the guardrail, it is avoided that a safety net is damaged and the entire part needs to be replaced. The safety net can be disassembled and assembled by rotating the fixing rod without complicated steps. The limit teeth on the movable half-clip cooperate with the fixed half-clip to prevent the movable half-clip and the fixed half-clip from relative rotation. The clamping block cooperates with the limit groove to prevent the fixing rod from rotating, which leads to the cancellation of the fixation of the fixed half-clip and the movable half-clip, thereby improving the safety of the connecting component.
