[0017] like Figures 1 to 5As shown, a rail-matching type corrugated compensator comprises a bellows main structure 1, and a connecting matching flange 2 is respectively provided at both ends of the bellows main structure 1, and the connecting matching flange 2 is provided with integral fastening matching holes 3 evenly distributed circumferentially, through which the overall installation and fastening matching is performed. The central axes of the integral fastening matching holes 3 on the two connecting matching flanges 2 are not on the same straight line, so that when the fixed structures on both sides are fastened, the acting forces are not on the same straight line, and the overall fastening strength is better. The outer side of the connecting matching flange 2 is provided with a first sliding matching column 4 and a second sliding matching column 5 evenly distributed circumferentially, and the first sliding matching column 4 and the second sliding matching column 5 are staggeredly distributed circumferentially, so that the strength of the main structure is better. The shapes of the first sliding matching column 4 and the second sliding matching column 5 are different, which can meet the needs of different specifications for matching. When in use, different positions can be selected for matching according to needs, and the flexibility of matching is stronger. The size of the outer position of the second sliding matching column 5 is smaller than the size of the inner position, and it has a reliable anti-slip effect when matching with the guide rail, and the matching stability is better. It is improved on the basis of the existing compensator, and two sets of evenly distributed sliding matching structures are arranged on the outside of the flange structure. When in use, it can be combined with the guide rail. During use, the compensator can perform axial movement compensation based on the guide rail, so that it can move within a safe range, avoiding damage to the main structure of the compensator due to excessive deformation, making the overall structure of the compensator safer and more durable. The fastening holes at both ends of the compensator adopt an eccentric design, and the overall stability is stronger when fastening and connecting.
[0018] Preferably, the first sliding fitting column 4 is a cylindrical structure, and the second sliding fitting column 5 is a trapezoidal structure, which has better structural stability, higher combined strength when fitting, and stronger durability.
[0019] Preferably, the projection shape of the second sliding fitting column 5 in the left-right direction is an isosceles trapezoid, which can further improve the fitting strength of this structure.
[0020] Preferably, the first sliding fitting column 4 and the second sliding fitting column 5 have the same thickness as the connecting fitting flange 2, so that the flatness of the main structure is better, the safety during use is more guaranteed, and it is more convenient to produce and process.
[0021] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention.
