Description

Technical Field

[0001] The utility model relates to the technical field of luggage locks, in particular to a buckle lock with an unlocking and stopping function. Background Art

[0002] The buckle locks used on luggage have evolved from the lock buckle. Generally, the buckle lock adds a lock body to the structure of the lock buckle, so that the buckle lock not only has the fastening function of the lock buckle, but also has the locking and anti-theft functions of the lock body.

[0003] For example, a Chinese patent document with the announcement number CN209482924U discloses a buckle lock, the technical solution of which is as follows: a base is provided with a slot; a shell and two snap rings, the other end of the shell is provided with a hook, a limiter is provided between the other ends of the two snap rings, the limiter is provided with a convex that can be engaged with the slot, one of the snap rings is provided with a torsion spring, and the torsion spring includes a first torsion spring and a second torsion spring; a lock body; when the convex of the limiter is engaged with the slot of the base, the hook of the shell cooperates with the buckle of the other opening and closing surface of the bag to limit, after the lock body is locked, the limiter and the shell cannot rotate, so the luggage is locked, and the first torsion spring is in an elastic deformation state; after the lock body is unlocked, the lock body releases the limit of the limiter, so that the limiter rotates to disengage the convex from the slot, the second torsion spring produces elastic deformation, and the elastic force generated by the elastic deformation of the first torsion spring drives the snap ring and the shell to rotate so that the hook is disengaged from the buckle of the other opening and closing surface of the bag, so that the luggage is unlocked, and the purpose of simple operation and quick unlocking is achieved.

[0004] Another example is a Chinese patent document with the announcement number CN218029618U, which discloses a PP box buckle lock, including an upper lock body and a lower lock body, wherein the lower lock body is provided with a lower lock shell and a lock buckle fixed to the lower lock shell, and the upper lock body is provided with an upper lock shell, a push-twist and a locking mechanism, wherein the push-twist can be elastically slidably mounted on the upper lock shell and partially exposed for operation, and the push-twist is provided with a lock hook capable of clamping the lock buckle; the locking mechanism includes a lock rod slidably mounted on the upper lock shell, and a lock core assembly and a password assembly capable of locking the lock rod, and a clearance hole is provided at the end of the lock rod, and the push-twist is provided with a limiting protrusion, and after the lock core assembly is inserted with a correct key and turned or after the password assembly enters a correct password, the lock rod can be freed from the restriction and move, so that the limiting protrusion is aligned with the clearance hole, and then the push-twist can slide to make its lock hook disengage from the lock buckle and unlock. After unlocking, the lock hook is separated from the lock buckle by pressing the elastically slidable push-twist, and the PP box lock adopts a push-twist unlocking method, and the finger operation position is large, which is convenient for unlocking.

[0005] Another example is a Chinese patent document with the announcement number CN107013095A, which discloses a password wheel reset structure for a PP box buckle lock, comprising a buckle cover, a boss is provided in the middle of one side of the buckle cover, a password wheel set is provided on the back of the boss, a password wheel reset rod for controlling the reset of the password wheel set is provided at the bottom of the password wheel set, a reset button for controlling the rotation of the password wheel reset rod and giving way to the password wheel set is provided at one end of the password wheel reset rod, the reset button extends from the front of the boss, and a reset control operating rod for controlling the rotation and reset of the password wheel reset rod is provided on one side of the password wheel reset rod. The number change method adopted is to complete the operation in two steps. When the password wheel is reset and changed, the reset button is pressed to sink, the reset rod pusher pushes the stopper to rotate a certain angle, the stopper releases the resistance to the password wheel, the password wheel is reset, and when the reset button returns to its position, when the control panel is pulled downward and rotated, the step pushes the reset protrusion to rotate, the stopper on the password wheel reset rod pushes the password wheel, the stopper pushes the reset rod pusher to rise, and the reset button returns to its position.

[0006] The Chinese patent document with publication number CN209482924U is the closest comparative document. Its locking principle is to limit the rotation of the limit part through the transmission part. The principles of key unlocking and password unlocking are to drive the transmission part to move horizontally, release the obstruction of the transmission part to the limit part, and manually swing (rotate) the limit part and the base fixed on one side of the luggage to make the shell rotate and separate from the other side of the luggage to achieve unlocking.

[0007] However, after the key is unlocked, the lock body needs to be reset before the key can be pulled out. During the reset process of the lock body, the transmission member also resets to the locked state. If the lock body is to remain unlocked after the key is pulled out, it cannot meet the demand. There are also buckle locks in the prior art that can remain unlocked after the key is pulled out, but the internal structure is complex and the manufacturing cost is high. Summary of the invention
