Description

Technical Field

[0001] The utility model relates to the technical field of buckle lock mechanisms, in particular to a double-linkage twisting buckle lock mechanism. Background Art

[0002] Most of the current handbags, backpacks, suitcases and other bags are provided with a locking structure for fixing the cover. At present, there are many styles of locks for various bags on the market, and they are varied. Although there are many kinds of bag locks on the market, there are magnetic, button, press and so on.

[0003] In the Chinese patent application number CN201510548879.8, a lock buckle structure and a suitcase with the lock buckle structure are proposed, wherein the lock body component includes a lock body tube and a sliding member slidably arranged in the lock body tube. When unlocking, the user gently pushes the lock body component to make the lock body component swing from longitudinal direction to transverse direction and be positioned by adsorption of the magnetic component. The lock body component is not easy to fall off by itself, and the sliding member can slide in the direction away from the bottom of the lock body tube; when locking, the user gently pushes the lock body component in the opposite direction to make the lock body component swing from transverse direction to longitudinal direction, and the sliding member can slide toward the bottom of the lock body tube under the action of gravity, so that the lock body component returns to its original position quickly and smoothly, and the sliding member plays a certain counterweight role, and the lock body component will not swing at will. The unlocking and locking operations of the lock buckle structure are convenient, and the reliability is high, which is convenient for users to use.

[0004] However, after studying the above patents and prior art, it can be found that the existing buckle lock mechanism often cannot have both functionality, interest and convenience, and needs to be improved. Therefore, a double-linkage twisting buckle lock mechanism is proposed here. Utility Model Content
