Description

Technical Field

[0001] The utility model relates to the technical field of safety nets with closely spaced meshes, in particular to a flame-retardant high-strength safety net with closely spaced meshes. Background Technique

[0002] The flame-retardant high-strength safety net with closely spaced meshes is generally used in construction projects, and its main function is for safety protection at the construction site. It can effectively prevent various objects at the construction site from freely falling, thus generating a buffering effect. Therefore, it is also called the "safety vertical net with closely spaced meshes for construction". That is the colored vertical net that generally surrounds the entire building during construction. Most of them are green, and some are blue or very few are of other colors.

[0003] Among the existing safety nets with closely spaced meshes, by setting fixed tensile belts on the upper and lower sides of the main body of the net surface, the tensile strength of the safety net with closely spaced meshes is improved. By configuring annular protrusions on the fixed tensile belts, the cutting force of the thousands of filaments acting directly on the safety net with closely spaced meshes is reduced, avoiding the tearing of the net surface due to force. By opening side matching connection holes on the left and right sides of the safety net surface, it is convenient for the splicing of the safety nets. Through optimizing the structural design, the safety net has a double-layer structure, greatly improving the impact resistance and use safety of the safety net.

[0004] However, in the actual use process of the above equipment, although the safety net can play an impact resistance and has good extensibility, when building materials with a large mass fall on the safety net, they will be ejected by the safety net with good extensibility and impact resistance, resulting in potential safety hazards. In view of this, we have proposed a flame-retardant high-strength safety net with closely spaced meshes. Summary of the Invention

[0005] The purpose of the utility model is to provide a flame-retardant high-strength safety net with closely spaced meshes to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A flame-retardant high-strength close-mesh net, including a close-mesh net, wherein a dropping clip assembly is arranged on the outer surface of the close-mesh net. The dropping clip assembly includes an upper fixing plate, and the upper fixing plate is movably connected to the outer surface of the close-mesh net. An activity groove is formed on the outer surface of the close-mesh net. A bolt is threadedly connected to the outer surface of the upper fixing plate, and the bolt passes through the activity groove and is threadedly connected to a lower fixing plate. A C-shaped clamping plate is fixedly connected to the outer surface of the upper fixing plate. One end of the C-shaped clamping plate is fixedly connected to the lower fixing plate. An L-shaped block is fixedly connected to the outer surface of the lower fixing plate, and a restricting body is fixedly connected to one end of the L-shaped block. A drop rope is fixedly connected to the outer surface of the activity groove, and a heavy object block is fixedly connected to one end of the drop rope. The restricting body is movably connected to the outer surface of the heavy object block. A moving groove is formed on the outer surface of the lower fixing plate, a spring is fixedly connected to the inner wall of the moving groove, a pushing block is fixedly connected to one end of the spring, a touching inclined plate is fixedly connected to one end of the pushing block, a connecting block is fixedly connected to the outer surface of the touching inclined plate, and a forward moving inclined plate is fixedly connected to one end of the connecting block.

[0007] Preferably, the restricting body is adapted to the heavy object block, so that the heavy object block can only perform vertical upward or vertical downward operations within the restricting body.

[0008] Preferably, the number of the dropping clip assemblies is two groups, and the two groups of dropping clip assemblies are mirror-symmetrically arranged on both sides of the close-mesh net with the central plane of the close-mesh net as the mirror plane, so that the protection effect is greatly improved.

[0009] Preferably, the central lines of the spring, the pushing block, and the moving groove are all on the same straight line, so that the pushing block can run smoothly during operation.

[0010] Preferably, a secondary clamping assembly is arranged on the outer surface of the forward moving inclined plate. The secondary clamping assembly includes an extrusion groove. An extrusion groove is formed on the outer surface of the forward moving inclined plate. A sliding block is slidably connected to the outer surface of the extrusion groove. An extrusion tooth is fixedly connected to one end of the sliding block, and an elastic telescopic plate is arranged on the outer surface of the extrusion tooth.

[0011] Preferably, the number of the extrusion teeth and the sliding blocks is several, and the several extrusion teeth and the several sliding blocks are arranged in a linear array on the outer surface of the forward moving inclined plate, so that the extrusion teeth can secondarily clamp irregularly falling buildings.

[0012] Compared with the prior art, the present utility model provides a flame-retardant high-strength close-mesh net, which has the following beneficial effects:

[0013] 1. When building materials falling from above hit the safety net with closely spaced meshes during daily use, the safety net will descend under pressure. Through the transmission of the suspension rope, the heavy object block will move vertically upward along the restricting body, causing the heavy object block to squeeze and touch the inclined plate. When the inclined plate is touched and subjected to the squeezing force, the pushing block will move forward, and the inclined surface of the forward-moving inclined plate will clamp the building materials hitting the safety net, thereby alleviating the rebounding force and ultimately solving the problem that the building materials will be ejected by the protective net with good extensibility and impact resistance after falling.

[0014] 2. When the inclined surface of the forward-moving inclined plate clamps the building materials hitting the safety net with closely spaced meshes, when the extrusion teeth are restricted by the falling building materials, the forward-moving inclined plate will continue to move forward, causing the elastic telescopic plate to contract. When the forward-moving inclined plate clamps the falling building materials, the extrusion teeth will perform a secondary reinforcement operation on the protruding parts of the irregular falling building materials, ultimately enhancing the more effective reinforcement effect on the irregular falling building materials.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1 - 5As shown in the figure, the present utility model provides a technical solution: a flame-retardant high-strength close-mesh net, including a close-mesh net 1. A clamping component 2 is arranged on the outer surface of the close-mesh net 1. The clamping component 2 includes an upper fixing plate 201. The upper fixing plate 201 is movably connected to the outer surface of the close-mesh net 1. An activity groove 203 is opened on the outer surface of the close-mesh net 1. A bolt 202 is threadedly connected to the outer surface of the upper fixing plate 201. The bolt 202 passes through the activity groove 203 and is threadedly connected to a lower fixing plate 205, so that when the close-mesh net 1 is stretched or contracted, the activity groove 203 can provide a stable limiting range. A C-shaped clamping plate 204 is fixedly connected to the outer surface of the upper fixing plate 201. One end of the C-shaped clamping plate 204 is fixedly connected to the lower fixing plate 205. The C-shaped clamping plate 204 fixes the lower fixing plate 205 and the upper fixing plate 201, and can also be fixed to an external component. An L-shaped block 206 is fixedly connected to the outer surface of the lower fixing plate 205. One end of the L-shaped block 206 is fixedly connected to a limiting body 207.

[0022] Furthermore, a pendant rope 210 is fixedly connected to the outer surface of the activity groove 203. One end of the pendant rope 210 is fixedly connected to a heavy object block 211. The outer surface of the heavy object block 211 is movably connected to the limiting body 207, so that the heavy object block 211 can only perform vertical upward or downward operations within the limiting body 207. A moving groove 208 is opened on the outer surface of the lower fixing plate 205. A spring 212 is fixedly connected to the inner wall of the moving groove 208. One end of the spring 212 is fixedly connected to a pushing block 213. One end of the pushing block 213 is fixedly connected to a touching inclined plate 209, so that when the touching inclined plate 209 is squeezed, the pushing block 213 will perform a forward operation in the moving groove 208. A connecting block 214 is fixedly connected to the outer surface of the touching inclined plate 209. One end of the connecting block 214 is fixedly connected to a forward moving inclined plate 215, so that when the forward moving inclined plate 215 moves forward, the inclined surface can clamp the building materials falling on the close-mesh net 1.

[0023] In an embodiment of the present utility model, the limiting body 207 is adapted to the heavy object block 211, such that the heavy object block 211 can only perform vertical upward or vertical downward operations within the limiting body 207. The number of the falling clip assemblies 2 is two groups, and the two groups of falling clip assemblies 2 are arranged on both sides of the safety net 1 in a mirror image with respect to the central plane of the safety net 1, greatly improving the protection effect. The central lines of the spring 212, the pushing block 213, and the moving groove 208 are all on the same straight line, enabling the pushing block 213 to operate smoothly during operation. A secondary clamping assembly 3 is provided on the outer surface of the forward moving inclined plate 215. The secondary clamping assembly 3 includes an extrusion groove 301. The extrusion groove 301 is formed on the outer surface of the forward moving inclined plate 215. A sliding block 302 is slidably connected to the outer surface of the extrusion groove 301. One end of the sliding block 302 is fixedly connected to an extrusion tooth 304. A resilient telescopic plate 303 is provided on the outer surface of the extrusion tooth 304. The number of the extrusion teeth 304 and the sliding blocks 302 is several, and several extrusion teeth 304 and several sliding blocks 302 are arranged on the outer surface of the forward moving inclined plate 215 in a linear array, enabling the extrusion teeth 304 to secondarily clamp irregularly falling building materials.

[0024] In addition, to solve the problem that when building materials with a large mass fall on the safety net, they will be ejected by the safety net with good extensibility and impact resistance, posing a safety hazard. In the present utility model, during daily use, when the building materials falling from above hit the safety net 1, the safety net 1 will perform a descending operation. Through the transmission of the hanging rope 210, the heavy object block 211 performs a vertical upward operation along the limiting body 207, causing the heavy object block 211 to squeeze and touch the trigger inclined plate 209. After the trigger inclined plate 209 is subjected to the squeezing force, the pushing block 213 will move forward, enabling the inclined surface of the forward moving inclined plate 215 to clamp the building materials hitting the safety net 1, thereby alleviating the rebounding force and ultimately solving the problem that the building materials will be ejected by the safety net with good extensibility and impact resistance after falling.

[0025] Moreover, when the inclined surface of the forward moving inclined plate 215 clamps the building materials hitting the safety net 1, when the extrusion teeth 304 are restricted by the falling building materials, the forward moving inclined plate 215 will continue to move forward, causing the resilient telescopic plate 303 to perform a contraction movement. When the forward moving inclined plate 215 clamps the falling building materials, the extrusion teeth 304 will perform a secondary reinforcement operation on the protruding parts of the irregular falling building materials, ultimately enhancing the more effective reinforcement effect on the irregular falling building materials.

[0026] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
