AI Technical Summary
Traditional closed-end zippers are prone to zipper head slippage and blockage during use, affecting smooth operation and potentially causing zipper damage, and lack an effective prevention mechanism.
A closed-end zipper with an adjustment mechanism and an anti-blocking mechanism was designed. The adjustment mechanism uses a bidirectional lead screw and a knob to adjust the movement of the threaded block to reduce blockage. The anti-blocking mechanism uses an elastic telescopic rod and a support block to flatten the zipper tape and prevent the zipper tape from not closing.
It effectively reduces clogging when the zipper head slides, improves the smoothness of zipper use and zipping efficiency, and enhances the stability and durability of the zipper.
