The sliding door cable tensioning mechanism further comprises a sliding cavity 700, wherein the sliding cavity 700 is a cavity formed in the upper shell 710 and the lower shell 720 after the upper shell 710 and the lower shell 720 are spliced, the sliding cavity 700 axially extends along the horizontal direction, and the sleeve seat 120 can be contacted with the inner wall surface of the sliding cavity 700 to axially slide along the sliding cavity 700. The sleeve 110 assembly 100 includes an inner end positioned within the sliding chamber 700 and an outer end capable of extending out of the sliding chamber 700.

The sliding door cable tensioning mechanism further includes a resilient member for abutting the sleeve 110 assembly 100 to apply a biasing force to the sleeve 110 assembly 100 to move it in the direction of the tensioning cable 800. Specifically, the direction of the tensioning cable 800 is the direction in which the outer end of the sleeve 110 assembly 100 extends out of the sliding cavity 700; the elastic member is a spring 200 having one end abutting the sliding chamber 700 and the other end abutting the outer end of the sleeve 110 assembly 100, and the spring 200 applies an elastic biasing force to the sleeve 110 assembly 100 so as to extend out of the sleeve 110, thereby tensioning the cable 800.

In this embodiment, to better guide the spring 200 to improve reliability, the spring 200 is sleeved on the outer wall of the sliding cavity 700 and has an axial overlapping area with the outer wall of the sliding cavity 700, and the inner sleeve 300 of the spring is disposed in the axial overlapping area and penetrates through the spring 200, the inner sleeve 300 of the spring provides internal guide for the spring 200, and deformation dislocation of the spring 200 can be avoided through the guiding action of the inner sleeve 300 of the spring, so that reliability of the sliding door cable tensioning mechanism is improved.

The tensioning effect of the sliding door inhaul cable tensioning mechanism is achieved through the following modes: when the wire cable 800 is relaxed and lengthened, the spring 200 pushes the sleeve 110 assembly 100 out of the sliding cavity 700 (i.e., to the right in fig. 1), changing the path of the sleeve 110 assembly 100, increasing the path length of the wire cable 800, absorbing the slack allowance of the wire cable 800, and tightening the loosened wire cable.
