[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the figure, this embodiment provides a convenient rail guard cover for rail vehicles, including a sleeper 1. The number of sleepers 1 is set to multiple, and two sets of rail frames 2 are symmetrically fixed on the upper end of the sleeper 1. Multiple sets of first rail guard covers 3 and second rail guard covers 4 are set on the upper end of the two sets of rail frames 2. The first rail guard covers 3 and the second rail guard covers 4 are adapted in size. One end of the first rail guard cover 3 is fixedly connected to a snap-fit ​​plate 31. The outer walls of the second rail guard cover 4 are provided with mounting structures 5 on both sides. The mounting structure 5 includes a limiting box 51 fixedly installed on the outer wall of the second rail guard cover 4. A pressing cap 52 is provided on the outside of the limiting box 51, and a connecting shaft 53 is rotatably installed on the pressing cap 52. The connecting shaft 53 is fixedly connected to a guide post 54. A reset spring 56 is sleeved on the outer wall of the guide post 54, and a snap-fit ​​cylinder 55 is fixedly connected to one end of the guide post 54. One end of the snap-fit ​​cylinder 55 is snapped onto the snap-fit ​​plate 31.

[0024] like Figures 3 to 4 As shown, the bottom of the pressing cap 52 is fitted to the outer wall of the limiting box 51. The limiting box 51 has a guide groove 57 inside. The guide post 54 is slidably connected inside the guide groove 57. One end of the reset spring 56 is fixedly connected inside the limiting box 51, and the other end is fitted to the snap-fit ​​cylinder 55. The second guard rail cover 4 and the snap-fit ​​plate 31 both have positioning slots 32 of the same size on both sides. One end of the snap-fit ​​cylinder 55 is adapted to the positioning slot 32.

[0025] The first guard rail cover 3 and the second guard rail cover 4 are aligned and snapped together. Then, the guide post 54 drives the snap-fit ​​cylinder 55 to splice and install the two guard rail covers together under the elastic force of the return spring 56. This avoids the problems of cumbersome operation and time-consuming and labor-intensive operation caused by fixing with bolts.

[0026] like Figure 5 As shown, the second guard rail cover 4 has a sealing groove 41 inside, and a rubber sealing ring 42 is fixedly installed inside the sealing groove 41. A rubber sealing gasket 43 is attached to the outer wall of the rubber sealing ring 42. The rubber sealing gasket 43 attached to the outer wall of the rubber sealing ring 42 is adapted to the sealing groove 41. The snap-fit ​​plate 31 is snapped into the sealing groove 41. Multiple sets of guard rail covers are connected in sequence, and the main bodies of multiple sets of first guard rail covers 3 and second guard rail covers 4 can be made of high-strength aluminum alloy.

[0027] Each guardrail cover has a rubber sealing ring 42 and a rubber sealing gasket 43 inside one end, which makes the guardrail covers relatively sealed when they are spliced ​​together. By making the guardrail covers into aluminum alloy, it ensures sufficient strength and rigidity to withstand the impact and vibration during vehicle operation, while also having a light weight, making it easy to install and maintain.

[0028] The working principle and operation process of this utility model are as follows: First, the operator places multiple sets of first guard rail covers 3 and second guard rail covers 4 on the upper end of the track frame 2 in sequence. Then, the locking plate 31 on the first guard rail cover 3 and the inner sealing groove 41 of the second guard rail cover 4 are aligned and locked together, so that the locking plate 31 squeezes the internal rubber sealing gasket 43 and rubber sealing ring 42, thereby sealing the guard rail covers relative to each other when they are joined, effectively preventing rainwater, dust, debris, etc. from entering the track interior, avoiding track rust and wear. After the first guard rail cover 3 and the second guard rail cover 4 are locked together, the pressing cap 52 is moved parallel to the limit box 51, causing the pressing cap 52 to rotate. Simultaneously, the guide post 54 on the connecting shaft 53 moves inward under the elastic force of the return spring 56, causing the guide post 54 to drive the snap-fit ​​cylinder 55 through the sealing groove 41 so that one end of it is aligned with the positioning slot 32 on the snap-fit ​​plate 31. This facilitates the quick installation and fixing of the two guard rail covers. When disassembly is required, the operator only needs to turn the pressing cap 52 so that it is perpendicular to the limit box 51. At the same time as the pressing cap 52 is turned, the bottom of the pressing cap 52 squeezes the limit box 51, causing the guide post 54 to drive the snap-fit ​​cylinder 55 to squeeze the return spring 56, causing the snap-fit ​​cylinder 55 to be displaced from the positioning slot 32. Then, the first guard rail cover 3 can be pulled out. The installation is relatively simple and convenient.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
