Description

Technical Field

[0001] The utility model relates to the technical field of metal guardrails, in particular to a metal guardrail that is easy to maintain. Background Art

[0002] Isolation guardrails are used to decorate courtyard green spaces, garden paths, and city avenues. The white and bright visual effect makes homes, cities, and living places more beautiful and more beautiful. This is the role of isolation guardrails.

[0003] Most metal guardrails do not have a buffering effect when in use. Therefore, when an object hits the metal guardrail, it is easy to cause serious damage to the metal guardrail and the object. It is not convenient to buffer the impact force, which makes the metal guardrail easy to deform. Therefore, we propose a metal guardrail that is easy to maintain. Utility Model Content

The utility model has the advantages of arranging an anti-collision tube and an anti-collision airbag. After the anti-collision tube is hit, the force of the impact can be buffered, thereby reducing the influence of the impact force on the connecting rod. Under the action of the buffer component, the buffering force of the anti-collision tube when it is hit is increased, and at the same time, it is convenient to restore the deformation of the anti-collision tube after the impact, etc., which solves the problem that most metal guardrails do not have a buffering effect when in use.

[0030] The connecting component 4 includes a connecting rod 41, which is arranged inside the mounting sleeve 31. The upper and lower ends of the connecting rod 41 are fixedly connected with mounting plates 42. The upper and lower sides of the front of the guardrail frame 2 are provided with mounting grooves 43, and the mounting plate 42 is arranged inside the mounting groove 43.

[0031] The buffer assembly 34 includes a buffer cylinder 341, in which buffer gas is arranged, the inner wall of the buffer cylinder 341 is slidably connected to the piston 342, one side of the buffer cylinder 341 is fixedly connected to the buffer rod 343, one end of the buffer rod 343 passes through one side of the inner wall of the buffer cylinder 341 to its surface, and the other side of the inner wall of the buffer cylinder 341 and the other side of the piston 342 are fixedly connected to the buffer spring 344.

[0032] The other side of the buffer cylinder 341 is fixedly connected to the inner wall of the anti-collision cylinder 32, one end of the buffer rod 343 is fixedly connected to the surface of the mounting sleeve 31, and the other side of the buffer cylinder 341 and the surface of the anti-collision cylinder 32 are jointly provided with two slow flow holes 345, the inner diameters of the two slow flow holes 345 are both set to be larger at one end and smaller at the other end, and a one-way component 35 is arranged inside the two slow flow holes 345.

[0033] The one-way component 35 includes a plug block 351, one end of which matches the side with a smaller inner diameter of the slow-flow hole 345, the left side of the plug block 351 is set in a trapezoidal shape, the left side of the plug block 351 is fixedly connected to a limiting rod 352, the left side of the rod wall of the limiting rod 352 is sleeved with a limiting ring 353, the left end of the limiting rod 352 is fixedly connected with a first limiting block, the surface of the limiting ring 353 and the inner wall of the slow-flow hole 345 are fixedly connected with a plurality of fixing rods 354, and the rod wall of the limiting rod 352 is sleeved with a return spring 355.

[0034] The left and right ends of the return spring 355 are fixedly connected to the right side of the fixing rod 354 and the left side of the blocking block 351 respectively.

[0035] During use, all the anti-collision cylinders 32 are mounted on the connecting rod 41 through the mounting sleeve 31. After all the anti-collision cylinders 32 are installed, the connecting rod 41 is installed on the guardrail frame 2, the guardrail frame 2 is installed on the stand 1, and the guardrail body is installed in the position of use;

[0036] When the guardrail is hit, the object hits the anti-collision cylinder 32 in the guardrail frame 2. Under the action of the anti-collision airbag 33 in the anti-collision cylinder 32, the impact force is buffered. At the same time, under the action of the buffer spring 344, the impact on the anti-collision cylinder 32 is buffered. After the anti-collision cylinder 32 is deformed due to the impact, the buffer cylinder 341 moves. At this time, the piston 342 on the buffer rod 343 squeezes the buffer gas in the buffer cylinder 341. The plug 351 in one of the slow flow holes 345 is affected by the air pressure in the buffer cylinder 341, so that the plug 351 moves away from the end with a smaller aperture in the slow flow hole 345. The buffer gas in the buffer cylinder 341 can be discharged through the slow flow hole 345.

[0040] The rear end of the bolt 442 is fixedly connected to the rear side of the inner wall of the mounting groove 43 .

[0041] During use, when fixing the connecting rod 41 to the guardrail frame 2, the mounting plate 42 on the connecting rod 41 is placed in the mounting groove 43, and the fixing block 441 is rotated to a vertical position on the bolt 442 at this time, and the fixing block 441 is rotated to the front at the same time, so that the fixing block 441 can pass through the through-hole 443 on the mounting plate 42. After the fixing block 441 passes through the through-hole 443 on the mounting plate 42, the fixing block 441 is rotated at this time so that the fixing block 441 can be misaligned with the through-hole 443. The fixing block 441 clamps the mounting plate 42 in the mounting groove 43, and the fixing block 441 is threadedly connected to the bolt 442. When the fixing block 441 is rotated, the fixing block 441 squeezes the mounting plate 42, thereby increasing the stability of the mounting plate 42 installed on the guardrail frame 2.
