Description

Technical Field

[0001] The utility model belongs to the technical field of road guardrails, and in particular relates to a road traffic guardrail capable of controlling the degree of damage. Background Art

[0002] Traffic guardrails are a type of traffic safety facility installed on the outside of the road shoulder, traffic divider, and sidewalk curbs. They absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from running off the road or entering the opposite lane, and minimizing injuries to passengers. However, various safety guardrails on the market still have various problems.

[0003] The existing patent (application number: CN201120461643.8) proposes a road safety guardrail, especially a road safety guardrail, which includes an upper crossbeam, a lower crossbeam and a column. The two ends of the upper crossbeam and the lower crossbeam are fixedly connected to the column. A vertical pipe is arranged between the upper crossbeam and the lower crossbeam. A base is arranged at the bottom of the column. The base has an outer shell and an inner cavity. A fixed layer is arranged at the bottom of the inner cavity. Since the base is filled with concrete, the stability of the guardrail is increased, making the guardrail more solid. The guardrail will not tilt or fall due to a slight collision, thereby ensuring the safety of the road.

[0004] However, traditional road traffic guardrails are usually tightly connected as a whole after assembly. When hit by a vehicle, they will cause the guardrails in a longer section around them to collapse and be damaged continuously, causing the damage to the guardrails to increase.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a road traffic guardrail that controls the degree of damage, and achieve the desired purpose.

[0007] In order to solve the above technical problems, the utility model provides a road traffic guardrail for controlling the degree of damage, including a guardrail body, the guardrail body including columns arranged symmetrically with each other, a base fixedly installed at the bottom of the columns, the base is a trapezoidal structure, sleeves are symmetrically arranged on the side walls of the columns, and a guardrail frame is detachably connected between the two symmetrical sleeves, the guardrail frame includes a horizontal column with a hollow interior, and plug columns are slidably installed at both ends of the horizontal column, the plug columns are inserted into the interior of the sleeve, an arc plate is slidably installed on the outer wall of the horizontal column, and a plurality of connecting rods are fixedly installed on the outer wall of the arc plate.

[0008] Furthermore, a sliding rod is fixedly installed on the inner wall of the arc plate, and the sliding rod slidably extends to the interior of the cross column and is fixedly connected to a trapezoidal block. A transmission rod is slidably installed inside the cross column, one side of the transmission rod is fitted with the trapezoidal block, and the other side of the transmission rod is fixedly connected to a first rack. A transmission gear is rotatably installed inside the cross column, and the transmission gear is meshed with the first rack. A second rack is fixedly installed on one side of the plug column, and the second rack is meshed with the transmission gear.

[0009] Furthermore, a rubber column is fixedly installed on the inner wall of the arc plate, and one end of the rubber column away from the inner wall of the arc plate is fixedly connected to the outer wall of the horizontal column.

[0010] Furthermore, a buffer spring is sleeved on the outer wall of the rubber column, one end of the buffer spring is fixedly connected to the inner wall of the arc plate, and the other end of the buffer spring is fixedly connected to the outer wall of the cross column.

[0011] Furthermore, an inclined surface is provided at one end of the transmission rod away from the first rack, and the inclined surface provided on the first rack is adapted to the outer wall of the trapezoidal block.

[0012] Furthermore, the first rack and the second rack are arranged in parallel and symmetrically, and the second rack is provided with teeth meshing with the transmission gear on the opposite side of the first rack.

[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0014] 1. In the utility model, when the arc plate is hit, the arc plate will drive the slide bar to slide inside the horizontal column, the slide bar can drive the trapezoidal block to move synchronously, the trapezoidal block drives the transmission rod to move in the direction away from the slide bar, the transmission rod drives the first rack to move synchronously, and the first rack drives the transmission gear to rotate when it moves. The transmission gear drives the second rack and the plug column to slide inside the horizontal column, so that the plug column is detached from the inside of the sleeve, and then the fence can be detached from the column when it is hit, eliminating the belt-like chain collapse of the guardrail, reducing the loss of the guardrail and the vehicle and the risk of greater personal injury, and improving safety.
