Description

Technical Field

[0001] This utility model belongs to the field of lock technology, and in particular relates to a press-type sealing bead structure. Background Technology

[0002] The sealing bead structure of existing locks is installed using methods such as riveting (using mechanical force to deform and lock it in place), adhesive bonding (using epoxy resin or anaerobic adhesive), or interference fit (forcibly pressed in and fixed by friction). For riveting, only mechanical operation is possible, and manual installation is not possible. It is also prone to problems such as hole deformation, sealing bead deformation, and loosening over long-term use. For adhesive bonding, the fastening is not good, and it may fall off after aging, affecting the anti-pry performance. For interference fit, high machining precision is required, it is prone to loosening after wear, and it requires tools and machinery, which is not conducive to manual operation.
