Description

Technical Field

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

[0002] As an entry-level racing car that is both entertaining and professional, karts have flexible and changeable requirements for the matching tracks. Due to the small size and high speed of karts, higher requirements are placed on the track guardrail design. At the same time, because karts often collide with the track guardrails during driving, the main requirements for track guardrails are flexible and convenient adjustment and certain buffering and energy absorption performance. Outdoor karts have higher speeds, with a maximum speed of 60 to 50 kilometers per hour. At this time, when the kart hits the buffer guardrail, the buffer support used to support the buffer guardrail will be subjected to a huge impact force, and the impact force is not necessarily perpendicular to the buffer guardrail, which can easily cause the buffer support to break.

[0003] The application document with application number 202311405267X provides a new type of racing track guardrail. An optional embodiment in the application document provides a rubber component, which includes a U-shaped rubber part. The U-shaped rubber part can initially adopt a flat structure and curl into a U-shaped structure during installation. The open end of the U-shaped rubber part is fixedly connected to a rubber support plate, and the rubber support plate is fixedly connected to the guardrail bracket; the application document improves the impact resistance of the buffer component to a certain extent, but when it is subjected to a severe impact, the opening of the U-shaped rubber pad will expand to both sides under force, and there are not enough support parts on both sides of the groove-shaped bracket body to absorb the force from the side, which can easily cause the rubber support plate to deform. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a kart track buffer support which has strong impact resistance, is not prone to fracture and deformation, and can provide a more stable support for the buffer guardrail.

[0005] The utility model is realized through the following technical scheme, providing a kart track buffer support, comprising a bracket and a buffer block, a buffer groove is vertically penetrated through the center of the top surface of the buffer block, the side wall of the buffer groove is closed along the circumferential direction, and the rear end of the buffer block is fixedly connected to the bracket.

[0006] The utility model provides a bracket to support the buffer block, and the buffer block can be used to buffer the impact from the kart. The buffer block can efficiently absorb the impact and is wear-resistant. The buffer block has no openings and will not be severely deformed or broken under the high-speed collision of the kart. The buffer groove can enhance the buffering capacity of the buffer block. When the buffer block is impacted, the buffer block can be deformed due to the existence of the buffer groove, thereby reducing the impact force on the support and preventing the support from tilting or breaking. After the front end of the buffer block is subjected to force, the force can be dispersed to both sides of the buffer groove, so that the rear component is subjected to more uniform force.

[0007] As an optimization, the bracket includes a slot bracket body and a base plate fixed at the lower end of the slot bottom plate of the slot bracket body, and the rear end of the buffer block is fixed to the slot bottom plate. The configuration of this optimization scheme fixes the buffer block by setting the slot bracket body, and the slot bracket body has better impact resistance. When the slot bracket body is subjected to impact force, it will not break or tilt like a single vertical rod. The base plate is set on the slot bracket body, which can make the slot bracket body have multi-point support, so that the slot bracket body can be more stably fixed on the ground.

[0008] As an optimization, the rear end of the buffer block is located inside the notch of the slot bracket body, and the two side walls of the buffer block are fixedly connected to the two side plates of the slot bracket body. With the setting of this optimization scheme, the slot bracket body can fix the buffer block in three directions, so as to cope with impacts in multiple directions and make the connection more stable.

[0009] As an optimization, a base plate is fixed at the bottom of both side plates of the trough-shaped bracket body. The configuration of this optimization scheme can make the trough-shaped bracket body more firmly fixed on the ground, so that the three directions of the trough-shaped bracket body can be fixed, so that the trough-shaped bracket body can cope with multi-directional impacts and the trough-shaped bracket body is not easy to tilt.

[0010] As an optimization, a deformation space is provided below the buffer block. In the configuration of this optimization solution, the deformation space can leave space required for the buffer block to deform downward, and when the buffer block is impacted from above, the buffer can deform downward.

[0011] As an optimization, the groove bracket body is fixedly connected to the buffer block by connecting bolts. The configuration of this optimization scheme allows the buffer block to be detachably mounted on the bracket, and is convenient for disassembly when the bracket or the buffer block needs to be repaired.

[0012] The beneficial effects of the utility model are as follows: the utility model can effectively absorb the impact force caused by the collision of the kart by utilizing the buffer block as a buffer element. In outdoor karts, the speed of the kart reaches 60 kilometers per hour. The buffer block has the advantages of efficient impact absorption, wear resistance, and strong adaptability. It will not break when the kart collides at high speed. The trapezoidal design of the buffer block and the design of the buffer groove can effectively reduce the impact of the impact force on the rear bracket. The bracket adopts a groove structure, which can be more firmly installed on the ground to prevent the bracket from breaking when it is impacted. At the same time, the buffer block is heat-resistant and cold-resistant, can be used outdoors for a long time, and has a longer service life, thereby reducing maintenance costs. At the same time, the various structures of the utility model are detachably connected by bolts, making installation easier. BRIEF DESCRIPTION OF THE DRAWINGS
