AI Technical Summary
Technical Problem
Existing expansion sleeves are prone to instability during expansion due to the splicing seams, leading to deformation at the rear and affecting the fastening effect.
Method used
The expansion sleeve adopts a zipper-type sealing structure. By alternately setting zipper-like interlocking gaps on the sleeve wall, and forming a protrusion on one side wall and a notch on the other side wall, a continuous zipper-type interlocking fit is formed, which enhances the structural stability.
Benefits of technology
It effectively prevents the expansion sleeve from being affected by the expansion at the front, avoids deformation, and ensures structural stability and fastening effect.

Abstract
The application discloses an expansion sleeve with a zipper type sealing structure, which comprises a sleeve body, the sleeve body is composed of an expansion part located at a lower part and a sleeve part located at an upper part, a plurality of slits are formed on the tube body of the expansion part, and the tube wall of the sleeve part is alternatively provided with mutually matched zipper type engaged slits along an axial direction; the tube body of the sleeve part is formed with zipper type engaged slits, a plurality of protrusions protruding into the slits are formed on one side wall of the sleeve part, and a plurality of notches corresponding to the protrusions are formed on the other side wall, the protrusions and the notches are sequentially and staggeredly distributed along the axial direction, and a continuous zipper type engagement is formed. The expansion sleeve is provided with the zipper type engagement, so that a stable expansion sleeve structure is formed, the front part of the expansion sleeve is prevented from affecting the rear part of the expansion sleeve during a stress expansion process, and the rear part of the expansion sleeve is effectively prevented from being deformed under stress.
