Description

Technical Field

[0001] The utility model relates to the technical field of buffer guardrails, in particular to the field of kart guardrails, and specifically refers to a racetrack buffer guardrail. Background Art

[0002] As an entry-level racing car that is both entertaining and professional, karts require flexible and changeable tracks. Due to the small size and high speed of karts, higher requirements are placed on the guardrail design of the track. At the same time, because karts often collide with the track guardrails during driving, the main requirements for the guardrails of the track are flexible and convenient adjustment, and certain buffering and energy absorption performance. Racing tracks generally use a combination of discarded tires and baffles to form kart guardrails. This method can reduce costs while playing a buffering role, but there are also some technical problems. For example, tires are inconvenient to maintain as guardrails, and the installation position of tires is difficult to fix and is easily displaced by external forces. When a kart hits a tire at high speed, a series of tires will be displaced. At this time, multiple tires need to be returned to their original positions, which is time-consuming and laborious.

[0003] The application document with application number 202311408267X provides a new type of racing track guardrail, which uses springs and guardrail supports instead of tires to play a buffering role, but this solution also has some technical problems. The connection between the spring and the guardrail is too simple, and the guardrail support is a long column type. When the guardrail support is impacted, the columnar support is prone to breakage, and the guardrail support only limits the end of the spring. When subjected to oblique force, there are no plates on both sides of the end of the spring to support it. All the force is concentrated at the connection at the end of the spring, and both the spring and the guardrail bracket may be damaged. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a racetrack buffer guardrail, the spring connection of which is more stable, the guardrail support is not easy to break, and the impact from all directions can be better absorbed.

[0005] The utility model is realized through the following technical scheme, which provides a racetrack buffer guardrail, a guardrail body, the guardrail body is connected to at least two guardrail supports, the guardrail support includes a buffer connector and a support body, the support body includes a support baffle and side panels fixedly arranged at the left and right ends of the support baffle, the bottom end of the side panel is fixedly connected to a bottom plate, and the two ends of the buffer connector are respectively connected to the guardrail body and the support baffle.

[0006] The utility model can prevent the kart from running out of the track by arranging the guardrail body, and can support the guardrail body and fix it on the ground by arranging the guardrail support. By arranging the buffer connection piece, when the kart hits the guardrail body, the buffer connection piece can play a buffering role, so as to protect the personal safety of the racer. The support baffle is used to fix the buffer connection piece, the side plate can enhance the stability of the support baffle, and the bottom plate fixes the side plate on the ground. When the support baffle is subjected to the impact force from the direction of the guardrail body, the side plate supports the support baffle, and the side plate can share a part of the force, so that the connection between the support baffle and the ground is more firmly established, and the support baffle is prevented from tilting.

[0007] As an optimization, a mounting groove for mounting the end of the buffer connector is formed between the two side plates. The configuration of this optimization solution can guide the end of the spring.

[0008] As an optimization, the fixing column and the limiting plate extending between the two spiral rings of the spring, the limiting plate is fixedly connected to the fixing column, the fixing column of the limiting piece at the front end of the spring is fixedly connected to the guardrail body, and the fixing column of the limiting piece at the rear end of the spring is fixedly connected to the support baffle. According to the setting of this optimization scheme, the spring has good elasticity, and the spring can automatically return to its original shape after the impact. The limiting piece is convenient for fixing the spring to other parts, the limiting plate can limit the lateral movement of the end of the spring, and the fixing column is used to fix the limiting plate to the guardrail body and the support baffle.

[0009] As an optimization, two springs are installed on the buffer connector, and the two springs are arranged in the up-down direction. With the arrangement of this optimization solution, the two springs can play a buffering role on both the upper and lower ends of the guardrail body, which can better protect the personal safety of the kart racer.

[0010] As an optimization, the bottom plate extends horizontally to a side away from the side plate. The arrangement of this optimization scheme can increase the force-bearing area of ​​the bottom plate, and the bottom plate is located outside the side plate, which has a better fixing effect on the side plate.

[0011] As an optimization, a warning strip is provided on the end surface of the guardrail body facing the track. The setting of this optimization scheme can serve as a warning to the racers and facilitate the racers to observe the position of the guardrail body.

[0012] The beneficial effects of the utility model are as follows: the guardrail body of the utility model is made of high-density polyethylene material, which has high impact resistance. The support body is groove-shaped, which can more effectively cope with the impact of the spring, so that the guardrail support is more firmly fixed on the ground, and the guardrail support is prevented from tilting or breaking due to the force from the direction of the guardrail body. The various components of the utility model are connected by bolts, which is convenient for the installation of the device. When a component is damaged, the connecting bolts can be removed and aligned with the corresponding part for repair and replacement. The utility model has a simple structure, low cost and easy installation. BRIEF DESCRIPTION OF THE DRAWINGS
