Description

Technical Field

[0001] This utility model relates to locks, and in particular to a four-hook inlaid bag lock. Background Technology

[0002] With the development of society and the economy, people have more opportunities to go out. When going out, they will inevitably carry some items for work or personal needs. In order to ensure the proper preservation and management of the items they carry, they generally use bags to preserve and manage the items they carry. Bags need to use combination locks. Combination locks are widely used in travel bags because they do not require keys and are very convenient to use.

[0003] Existing combination locks for bags typically consist of one or two hooks. A combination lock with one hook secures two zipper tabs, while a combination lock with two hooks secures one zipper tab each. Because the zipper tabs have holes, the part where they engage with the hooks is relatively fragile and prone to breakage under increased external force, causing the combination lock to malfunction.

[0004] This utility model provides a four-hook inlaid bag lock based on the above-mentioned defects. It has four hook positions, and every two hooks restrict one zipper piece, which can improve the connection strength between the zipper piece and the hooks. Summary of the Invention
