Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a high-strength, easily disassembled zinc-steel guardrail. Background Technology

[0002] Zinc-steel guardrails are guardrails made of zinc alloy materials. They have many excellent properties and are widely used in construction, industry, agriculture, public facilities and other fields.

[0003] However, most of the existing easily disassembled zinc-steel guardrails are fixed by bolts through holes in the connecting rods and holes in the crossbeams, which requires multiple people to work together, thus increasing working time and reducing work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength, easily disassembled zinc-steel guardrail.

[0005] This utility model is achieved using the following technical solution: a high-strength, easily disassembled zinc-steel guardrail, comprising a connecting rod, an upper crossbeam on one side of the connecting rod, a lower crossbeam on one side of the connecting rod, limit grooves at the top of both ends of the upper and lower crossbeams, rotating fixing components fixedly connected to both sides of the connecting rod, a flat pad fitted on the inner wall of the upper crossbeam, a snap-fit ​​pad fitted on the inner wall of the lower crossbeam, a vertical rod between the upper and lower crossbeams, and a support plate fixedly connected to the bottom of the connecting rod, with bolts threaded onto the inner wall of the support plate;

[0006] The rotating fixing assembly includes an upper button shell, a limit post fixedly connected to the surface of the upper button shell, a spring fixedly connected to the inner wall of the upper button shell, a lower button shell fixedly connected to one end of the spring, a V-shaped limit groove opened on the inner wall of the lower button shell, a fixing plate fixedly connected to the bottom of the lower button shell, a fixing ring fixedly connected to the surface of the lower button shell, and a U-shaped groove rotatably connected to the surface of the lower button shell.

[0007] With the above technical solution, by pressing the upper button shell, it slides downwards, and the limiting post also slides downwards along the inner wall of the V-shaped limiting groove, driving the lower button shell to move, thereby causing the fixing plate to rotate. Then, the limiting post enters the other end of the V-shaped limiting groove along the inner edge of the V-shaped limiting groove, thereby realizing the rotation of the fixing plate inside the upper and lower crossbeams, and thus realizing the quick disassembly of the guardrail.

[0008] As a further improvement to the above solution, two rotating fixing components are provided, and the two rotating fixing components are symmetrically distributed with the connecting rod as the center.

[0009] As a further improvement to the above solution, the surface of the upper button housing is slidably connected to the inner wall of the lower button housing.

[0010] The above technical solution uses a spring to reset the button housing after it is pressed down.

[0011] As a further improvement to the above solution, two limiting posts are provided, and the button shells above the two limiting posts are centrally symmetrically distributed.

[0012] As a further improvement to the above solution, the surface of the limiting post is slidably connected to the surface of the V-shaped limiting groove.

[0013] The above technical solution allows the lower button housing to rotate by sliding the limiting post within the V-shaped limiting groove.

[0014] As a further improvement to the above solution, the surface of the fixing plate is movably connected to the inner wall of the limiting groove.

[0015] As a further improvement to the above solution, the inner wall of the U-shaped groove is movably connected to the surface of the upper crossbeam, and the inner wall of the U-shaped groove is movably connected to the surface of the lower crossbeam.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features a rotating fixing component. Specifically, by pressing the upper button shell, it slides downwards, and the limiting post slides downwards along the inner wall of the V-shaped limiting groove, causing the lower button shell to move. This rotates the fixing plate, and the limiting post moves along the inner edge of the V-shaped limiting groove to the other end of the V-shaped limiting groove, thereby enabling the fixing plate to rotate inside the upper and lower crossbeams, and thus achieving quick disassembly of the guardrail.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5 This embodiment of a high-strength, easily disassembled zinc-steel guardrail includes a connecting rod 1, an upper crossbeam 2 on one side of the connecting rod 1, a lower crossbeam 3 on one side of the connecting rod 1, limit grooves 4 at the top of both ends of the upper crossbeam 2 and the lower crossbeam 3, rotating fixing components 5 fixedly connected to both sides of the connecting rod 1, a flat pad 6 sleeved on the inner wall of the upper crossbeam 2, a snap-fit ​​pad 7 sleeved on the inner wall of the lower crossbeam 3, a vertical rod 8 between the upper crossbeam 2 and the lower crossbeam 3, a support plate 9 fixedly connected to the bottom of the connecting rod 1, and bolts 10 threadedly connected to the inner wall of the support plate 9.

[0028] The rotating fixing assembly 5 includes an upper button shell 501. A limiting post 502 is fixedly connected to the surface of the upper button shell 501. A spring 503 is fixedly connected to the inner wall of the upper button shell 501. One end of the spring 503 is fixedly connected to a lower button shell 504. A V-shaped limiting groove 505 is opened on the inner wall of the lower button shell 504. A fixing plate 506 is fixedly connected to the bottom of the lower button shell 504. A fixing ring 507 is fixedly connected to the surface of the lower button shell 504. A U-shaped groove 508 is rotatably connected to the surface of the lower button shell 504. When the upper button shell 501 is pressed, it slides downward. The limiting post 502 also slides downward along the inner wall of the V-shaped limiting groove 505, causing the lower button shell 504 to move, thereby causing the fixing plate 506 to rotate. Subsequently, the limiting post 502 enters the other end of the V-shaped limiting groove 505 along the inner edge of the V-shaped limiting groove 505, thereby realizing the rotation of the fixing plate 506 inside the upper crossbeam 2 and the lower crossbeam 3, thus realizing the quick disassembly of the guardrail.

[0029] There are two rotating fixing components 5, which are symmetrically distributed around the connecting rod 1.

[0030] The surface of the upper button housing 501 is slidably connected to the inner wall of the lower button housing 504.

[0031] There are two limit posts 502, and the button shells 501 are symmetrically distributed above the two limit posts 502.

[0032] The surface of the limiting post 502 is slidably connected to the surface of the V-shaped limiting groove 505.

[0033] The surface of the fixed plate 506 is movably connected to the inner wall of the limiting groove 4.

[0034] The inner wall of the U-shaped groove 508 is movably connected to the surface of the upper crossbeam 2, and the inner wall of the U-shaped groove 508 is movably connected to the surface of the lower crossbeam 3.

[0035] The implementation principle of a high-strength, easily disassembled zinc-steel guardrail in this application embodiment is as follows: During installation, the flat pads 6 are sequentially installed into the corresponding slots on the upper crossbeam 2, and then the buckle pads 7 are sequentially installed into the corresponding slots on the lower crossbeam 3. The connecting rod 1 is then erected and fixed to the ground by rotating the bolts 10. The upper crossbeam 2 and the lower crossbeam 3 are placed on the inner wall of the U-shaped groove 508, and the fixing plate 506 is inserted into the interior of the upper crossbeam 2 and the lower crossbeam 3 through the limiting groove 4. At the same time, the upper button shell 501 is pressed, and it slides downward. The limiting post 502 also slides downward along the inner wall of the V-shaped limiting groove 505, driving the lower button shell 504 to move, thereby causing the fixing plate 506 to rotate. Subsequently, the limiting post 502 slides downward along the V-shaped limiting groove. The inner edge of 505 enters the other end of the V-shaped limiting groove 505, thereby rotating the fixing plate 506 by 90° and fixing it inside the upper crossbeam 2 and lower crossbeam 3, thus fixing the upper crossbeam 2 and lower crossbeam 3. Then, the vertical rod 8 is inserted from the slot on the upper crossbeam 2 and lower crossbeam 3, thus completing the quick installation of the guardrail. When the guardrail is to be disassembled, press the upper button shell 501. Due to the elastic force of the spring 503, the limiting post 502 slides along the inner wall of the V-shaped limiting groove 505 to the other end, thereby causing the lower button shell 504 to rotate in the opposite direction and drive the fixing plate 506 to rotate in the opposite direction by 90°, thus removing the upper crossbeam 2 and lower crossbeam 3 from the inside of the U-shaped groove 508, thus realizing the quick disassembly of the guardrail.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
