[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] First embodiment:

[0028] See also Figures 1-4 As shown, the present invention provides a rail with a shock-absorbing and protective function, comprising a vertical portion 1, wherein the top and bottom of the vertical portion 1 are connected to a transmission portion 102 and a fixed portion 101, respectively. The bottom surface of the fixed portion 101 is provided with a bottom groove 103 extending into the interior of the vertical portion 1, and an elastic member 2 is provided inside the bottom groove 103. The bottom of the elastic member 2 is arranged corresponding to the bottom surface of the fixed portion 101, and the bottom surface of the elastic member 2 is an arc surface that convexes downward away from the vertical portion 1. When supporting the transmission portion 102, the fixed portion 101 is used to form a support for the transmission portion 102, and a triangular support frame structure is formed between the fixed portion 101, the vertical portion 1, and the transmission portion 102. After the rail is fixed, it has a good supporting effect on the rail. The support effect of the transmission portion 102 on the rail is better; and the bottom groove 103 extends into the interior of the vertical portion 1, which can also reduce the use of steel. The elastic member 2 inside the bottom groove 103 can absorb the vibration and impact generated by the train running, thereby reducing the impact force and wear on the track bed, and improving the service life of the rail.

[0029] The second embodiment is different from the first embodiment in that:

[0030] The top of the bottom groove 103 is a triangular structure and extends to the interior of the vertical part 1. The bottom of the bottom groove 103 is a trapezoidal structure. The triangular structure, the trapezoidal structure and their connections all have arc transitions. The arc transition can smoothly distribute the transmission of force, reduce local stress concentration, and make the vertical part 1 more stable as a whole. The smooth transition can effectively reduce the impact of vibration on the vertical part 1 generated during use. Furthermore, the elastic member 2 includes an upper extension part 201 and a lower support part 202. The upper extension part 201 and the lower support part 202 are respectively arranged corresponding to the triangular and trapezoidal structures of the bottom groove 103. The elastic support for the vertical part 1 is formed by the elastic member 2 inside the vertical part 1. After the rails are fixed by the splint, the elasticity of the elastic member 2 can be used to effectively absorb part of the vibration and impact generated during the operation of the train. At the same time, the shock absorption effect helps to reduce the noise generated during the operation of the train and improve the comfort of passengers.

[0031] Both ends of the vertical portion 1 are inclined at the same angle, and the inclined surfaces cooperate to form a connection match between two adjacent vertical portions 1. In a preferred embodiment, the vertical portion 1, the fixing portion 101 and the transmission portion 102 are integrally formed.

[0032] The third embodiment is different from the first embodiment in that:

[0033] A skeleton 3 is provided inside the elastic member 2. The cross section of the skeleton 3 is in an inverted "T" shape. The vertical end of the skeleton 3 is arranged corresponding to the upper extension portion 201, and the horizontal end of the skeleton 3 is arranged corresponding to the lower support portion 202. The skeleton 3 is used to support the elastic member 2, thereby enhancing the structural stability of the elastic member 2 and reducing deformation and expansion. The reinforcing material makes the elastic member 2 more stable when subjected to force, maintaining excellent elasticity and recovery, thereby forming a support for the opposing portion 1.

[0034] Furthermore, a rib plate 302 is connected between the vertical end of the skeleton 3 and the horizontal end of the skeleton 3, and a feed hole 301 is provided on the skeleton 3. The feed hole 301 can form a passage for the material of the elastic part 2, which helps to flow through the elastic part 2, so that the elastic part 2 can be evenly distributed on the outside of the skeleton 3, forming a wrapping for the skeleton 3, thereby ensuring the support effect for the elastic part 2.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
