Description

Technical Field

[0001] This utility model belongs to the technical field of bridge protection facilities, specifically a bridge guardrail anti-throw net that is easy to assemble and disassemble. Background Technology

[0002] Bridge anti-throw nets are protective devices installed on bridge guardrails to prevent pedestrians or passengers from throwing objects off the bridge, ensuring the safety of roads, traffic, and waterways below. Currently, most existing bridge anti-throw nets are installed using integral welding or bolt fixing methods, which are overly cumbersome and require a large amount of manpower for installation and dismantling.

[0003] Therefore, this utility model provides a bridge railing anti-throw net that is easy to assemble and disassemble. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a bridge guardrail anti-throw net that is easy to assemble and disassemble is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The bridge railing anti-throw net that is easy to assemble and disassemble includes a post and a net panel. The post has a cylindrical structure and a groove is opened on the side of the post facing the net panel. T-shaped sliding rods are fixedly connected to both sides of the net panel. The T-shaped sliding rods pass through the groove and are connected to the post. The T-shaped sliding rods can move on the groove to insert the net panel between the two posts for fixation, which facilitates quick installation and disassembly of the anti-throw net. The upper end of the post is provided with an external threaded connecting nut. The height of the net panel is the same as the bottom surface of the nut. By tightening the nut, the up and down movement of the net panel is restricted, which facilitates assembly and disassembly while preventing it from slipping out and falling off during daily use.

[0006] Preferably, the width of the T-shaped slide bar is less than the inner diameter of the column, and the width of the narrow side of the T-shaped slide bar is the same as the width of the slide groove, ensuring that the T-shaped slide bar can move on the slide groove without shaking. A first threaded hole is provided on the upper part of the side wall of the column, and a second threaded hole is provided on the upper part of the side wall of the T-shaped slide bar. A screw is fixed through the first threaded hole and the second threaded hole. The screw passes through the first threaded hole and the second threaded hole to help fix the anti-throw net, ensuring that the anti-throw net is locked and prevented from falling off, thus meeting the safety protection requirements.

[0007] Preferably, a base is fixedly connected to the lower end of the column, and an expansion bolt is provided through the base to fix the guardrail. The column is fixed by the expansion bolt to ensure that the anti-throw net is tightly fixed to the guardrail.

[0008] Preferably, the mesh includes a mesh surface and a mesh frame. The mesh is made of alloy material and the surface of the mesh is coated with an anti-rust coating. The alloy material can provide the toughness of the anti-throw net and is lightweight, making it easy to install and transport. The anti-rust coating can extend its service life.

[0009] The beneficial effects of this utility model are as follows: 1. The T-shaped sliding rod and sliding groove enable rapid vertical installation between the mesh and the post without the need for complicated installation tools, simplifying the installation and disassembly process and improving installation and disassembly efficiency.

[0010] 2. The use of nuts, first threaded holes, second threaded holes, and screws ensures a more secure fixation between the mesh and the posts, guaranteeing the stability of the anti-throw net and meeting safety protection requirements. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0014] Specific implementation examples are given below.

[0015] like Figures 1 to 3As shown in the figure, a bridge railing anti-throw net that is easy to assemble and disassemble according to an embodiment of the present invention includes a post 1 and a mesh 2. The post 1 has a cylindrical structure, and a groove 3 is opened on the side of the post 1 facing the mesh 2. T-shaped sliding rods 4 are fixedly connected to both sides of the mesh 2. The T-shaped sliding rods 4 pass through the groove 3 and are connected to the post 1. The T-shaped sliding rods 4 can move on the groove 3 to insert the mesh 2 between the two posts 1 for fixation, which facilitates quick installation and disassembly of the anti-throw net. The upper end of the post 1 is provided with an external threaded connecting nut 5. The height of the mesh 2 is the same as the bottom height of the nut 5. By tightening the nut 5, the up and down movement of the mesh 2 is restricted, which facilitates assembly and disassembly while preventing it from slipping out and falling off during daily use. The width of the T-shaped sliding rod 4 is less than the inner diameter of the post 1, and the width of the narrow side of the T-shaped sliding rod 4 is the same as the width of the groove 3, ensuring that the T-shaped sliding rod 4 can move on the groove 3. The structure is movable without shaking. A first threaded hole 6 is provided on the upper side wall of the upright 1, and a second threaded hole 7 is provided on the upper side wall of the T-shaped sliding rod 4. A screw 8 is fixed through the first threaded hole 6 and the second threaded hole 7. The screw 8, passing through the first threaded hole 6 and the second threaded hole 7, assists in fixing the anti-throw net, ensuring the anti-throw net is locked tight and prevents detachment, meeting safety protection requirements. A base 9 is fixedly connected to the lower end of the upright 1. An expansion bolt 10 is provided through the base 9 to fix the guardrail 11. The upright 1 is fixed with the expansion bolts to ensure the anti-throw net is tightly fixed to the guardrail 11. The net panel 2 includes a mesh surface 12 and a frame 13. The net panel 2 is made of alloy material, and the surface of the net panel 2 is coated with an anti-rust coating. The alloy material provides the anti-throw net with toughness and is lightweight, making it easy to install and transport. The anti-rust coating extends its service life.

[0016] Working principle: During operation, the distance between the T-shaped sliding rods 4 fixed on both sides of the mesh 2 is measured. Based on the measured distance, the base 9 at the lower end of the column 1 is fixed to the guardrail 11 with expansion bolts 10. The T-shaped sliding rods 4 on both sides of the mesh 2 are inserted into the cavity of the column 1. The wide side of the T-shaped sliding rod 4 is smaller than the inner diameter of the column 1, and the narrow side of the T-shaped sliding rod 4 is the same width as the sliding groove 3. The T-shaped sliding rod 4 is slid through the sliding groove, which moves the mesh 2 downward to the surface of the base 9. The nut 5 is tightened on the upper end of the column 1 to fix the mesh 2. The screw 8 is rotated through the first threaded hole 6 and the second threaded hole 7 to fix the column 1 and the mesh 2, completing the installation. When disassembling, the screw 8 and the nut 5 are removed. The T-shaped sliding rod 4 is slid away from the sliding groove 3 by grasping the mesh frame 13. The mesh 2 is removed, the expansion bolts 10 are pulled out, the base 9 and the guardrail 11 are separated, and the column 1 is removed, completing the disassembly.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
