However, as the train passes by, the rigidity of the clamp is poor, which can easily cause the clamp to deform or break.

[0020] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] Please refer to Figure 1-4 A variable-section anti-slip joint clamp comprises a joint clamp body 2, wherein the joint clamp body 2 is provided with a plurality of ribs on a side away from the rail 1, and a plurality of assembly holes 21 are provided on the joint clamp body 2, and a sleeve 3 is provided in the assembly hole 21, wherein the circumference of the sleeve 3 is provided with an external thread, and the inner wall of the assembly hole 21 is provided with an internal thread matching the external thread, and the sleeve 3 is matched with the assembly hole 21 through a thread. When two adjacent rails 1 are spliced, joint clamp bodies 2 are respectively provided on both sides of the joint of the rails 1, and a through hole 11 is provided on the rail 1. The two joint clamp bodies 2 are connected to the rail 1 at the assembly hole 21 and the through hole 11 by high-strength bolts 4.

[0022] Depend on Figure 1-2 It can be seen that the joint clamp body 2 on both sides is used to connect two rails 1, the rail 1 is provided with a through hole 11, and the joint clamp body 2 is provided with an assembly hole 21 corresponding to the through hole. When in use, the sleeve 3 is installed in the assembly hole 21, and then the high-strength bolt 4 is inserted, and the end of the high-strength bolt 4 is fixed by a high-strength flat washer and a high-strength nut 5.

[0023] In actual use, the inner diameter of the through hole 11 on the rail 1 is generally larger than the outer diameter of the high-strength bolt 4, which makes it easy for the high-strength bolt and the joint clamp body 2 to slide on both sides of the rail during connection. Therefore, the establishment of the sleeves 3 on both sides can restrain the high-strength bolt 4 and the joint clamp body 2, thereby increasing the tightness of the connection.

[0024] In this embodiment, the ribs include a first rib 22, a second rib 23 and a third rib 24. The first rib 22 is parallel to the third rib 24. The two ends of the second rib 23 are respectively connected to the first rib 22 and the third rib 24. The first rib 22, the second rib 23 and the third rib 24 are arranged in an "I" shape.

[0025] The length of the first rib 22 is consistent with the length of the joint clamp body 2, and its thickness is 8-10mm, while the thickness of the second rib is 6mm and the width is 54mm. The establishment of the first rib increases the horizontal stiffness above the joint clamp body 2, and the "I" shape of the first rib 22, the second rib 23 and the third rib 24 can increase the overall connection stiffness of the rail and avoid problems such as flexible deformation and breakage of the joint clamp body 2.

[0026] Here, since the first rib 22, the second rib 23 and the third rib 24 are arranged on one side of the joint clamp body 2, the cross-section of the joint clamp body 2 is changed, and the establishment surface of the sleeve 3 slides or loosens as a whole, thereby achieving a variable cross-section to increase stiffness and anti-slip effect, so as to maintain stability when the train passes.

[0027] Based on the above embodiment, the sleeve 3 may also be an eccentric threaded sleeve 301 , in which an eccentric hole 302 is provided. The eccentric threaded sleeve 301 is suitable for scenarios where the rail through hole 11 and the assembly hole 21 do not completely correspond.

[0028] Please refer to Figure 5 When in use, the through hole 11 on the rail 1 partially overlaps with the assembly hole 21 on the joint clamp body 2. At this time, the sleeve 3 in the first installation embodiment cannot meet the smooth passage of the high-strength bolt; therefore, when the through hole 11 partially overlaps with the assembly hole 21, an eccentric threaded sleeve 301 is installed in the assembly hole 21. After installation, the eccentric hole 302 on the eccentric threaded sleeve 301 corresponds to the partially overlapping position (the through hole 11 and the assembly hole 21). After the correspondence, the high-strength bolt is inserted into the eccentric hole 302 (that is, the overlapping position of the through hole 11 and the assembly hole 21), thereby meeting the assembly connection, thereby preventing the rail joint from loosening.

[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
