[0005] Further, in the above technical scheme, the pull buckle part is provided with a rubber pad on the inner side, which can realize buffering during pulling, reduce the instantaneous impact force during pulling, and improve the service life of the whole chain ring body.

[0006] Further, in the above technical scheme, the diameter of the pull buckle part is greater than that of the cross section of the chain ring body, which facilitates the rapid entry of the chain ring body into the pull buckle part to realize the pulling effect.

[0007] Further, in the above technical scheme, the chain ring body is further provided with a nylon sleeve on the outside, which can realize stable conduction effect during pulling.

[0008] Further, the two ends of the arc-shaped spring sheet are connected with the inner wall of the chain ring body, and the reinforcing end is arranged at the connection position, which can strengthen the strength of the two ends of the arc-shaped spring sheet and reduce the damage caused by impact.

[0009] Further, the reinforcing end and the arc-shaped spring sheet are in an integrated structure, which can significantly improve the use strength and service life of the arc-shaped spring sheet.

[0010] The high-stability elevator balance compensation chain has high stability, realizes guiding pulling force through the spring sheet rebound, realizes stable pulling of the compensation chain through the pull buckle part, improves the overall service life, and is convenient to widely popularize and use.

[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0015] See Figure 1 As shown in the figure, a high-stability elevator balance compensation chain includes a waist-shaped chain ring body 1, the long side of the chain ring body 1 is symmetrically provided with an outwardly protruding pull buckle part 2, the two ends of the chain ring body 1 are provided with arc-shaped spring sheets 3 on the arc-shaped inner side, the arc-shaped spring sheets 3 protrude inwardly, the arc-shaped spring sheets 3 form a first gap 4 therebetween, and the first gap 4 is smaller than the diameter of the cross section of the chain ring body 1; the chain ring body 1 and the chain ring body 1 are connected through the pull buckle part 2 at the head and tail.

[0016] The rubber pad 5 is mounted in the inside of the pulling buckle 2. The diameter of the pulling buckle 2 is larger than the diameter of the cross section of the chain ring body 1. The nylon sleeve 6 is sleeved on the outside of the chain ring body 1. The reinforcing end 7 is arranged at the connecting position between the two ends of the arc spring sheet 3 and the inner wall of the chain ring body 1. The reinforcing end 7 is an integral structure with the arc spring sheet 3.

[0017] The use principle of the high-stability elevator balance compensation chain is as follows:
