Detailed Description

the present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of an external fixing lock according to an embodiment of the present invention in a state of locking with a zipper 100, where the external fixing lock includes a housing 1, and a coded lock assembly 2, a key lock assembly 3, and a limiting cover 4 disposed on the housing 1. Fig. 2 is a partial section on the basis of fig. 1 to show the internal structure of the position-limiting cover 4 and the matching relationship with the housing 1 and other components, the housing 1 is further provided with a lock cylinder 11, the distance between the upper end surface of the lock cylinder 11 and the lower end surface of the position-limiting cover 4 is smaller than the thickness of the zipper 100, and the lock cylinder 11 is matched with the through hole 110 of the zipper 100. When the external fixing lock is in a locking state, the zipper 100 is sleeved on the lock cylinder 11 through the through hole 110 of the external fixing lock, the limiting cover 4 covers the lock cylinder 11, so that the zipper 100 cannot be separated from the lock cylinder 11, the lock cylinder 11 limits the radial movement of the zipper 100 along the through hole 110, and the limiting cover 4 limits the axial movement of the zipper 100 along the through hole 110, so that locking is realized. When the coded lock assembly 2 and the key lock assembly 3 are both in a locking state, the limiting cover 4 is limited and cannot move, so that the limiting cover 4 keeps limiting the zipper 100, and an anti-theft protection effect is achieved. When one of the code lock assembly 2 and the key lock assembly 3 is in an unlocking state, the limiting cover 4 can move to the limiting cover 4 along the width direction of the shell 1 and is staggered with the lock cylinder 11, namely, the limiting of the limiting cover 4 on the zipper 100 is released, and the zipper 100 can be separated from the lock cylinder 11 to further realize unlocking. This external fixation lock only can realize locking and unblock through spacing lid 4 and lock post 11 and zip fastener 100 cooperation, compares in prior art external fixation lock part still less, and the structure is also simpler, and then makes the operation when locking and unblock also more simple and convenient.

As shown in fig. 2, the external fixing lock further includes a limiting block 5 disposed in the housing 1, and when the limiting cover 4 covers the lock cylinder 11 to lock, the limiting block 5 limits the limiting cover 4 so that the limiting cover 4 cannot move to unlock. When the limiting block 5 is pressed to be moved to be staggered with the limiting cover 4, the limiting of the limiting block 5 on the limiting cover 4 is removed, and the limiting cover 4 can be moved to realize unlocking. The limiting block 5 is linked with the coded lock assembly 2 and the key lock assembly 3 simultaneously in a linkage mode, and when the coded lock assembly 2 and the key lock assembly 3 are both in a locking state, the limiting block 5 cannot move; when one of the coded lock assembly 2 and the key lock assembly 3 is in an unlocking state, the limiting block 5 can be pressed to move, and the limiting cover 4 can move to realize unlocking. When the unlocking is realized by moving the limiting cover 4, the limiting cover 4 plays a role in separating the limiting block 5, so that the limiting block 5 cannot reset. Stopper reset spring 500 is equipped with between stopper 5 and the casing 1, and stopper 5 removes to the in-process that staggers with spacing lid 4, and stopper reset spring 500 produces elastic deformation. The limiting cover 4 is hinged to a button 41, the button 41 is pressed, the button 41 pushes the limiting block 5 to move, and the button 41 is arranged, so that the limiting block 5 and the limiting cover 4 can move conveniently. A button return spring 42 is provided between the button 41 and the stopper cover 4, and when the button 41 is pressed, the button return spring 42 is elastically deformed.

Fig. 3 is an exploded schematic view of the external fixing lock, and as shown in fig. 2 and fig. 3, a linkage member 6 is further disposed in the housing 1, the linkage member 6 is located below the limiting block 5, the linkage member 6 is linked with the coded lock assembly 2 and the key lock assembly 3, and the linkage member 6 is provided with a relief hole 61. When the coded lock assembly 2 and the key lock assembly 3 are both in a locked state, the abdicating hole 61 of the linkage piece 6 is staggered with the limiting block 5, and the limiting block 5 cannot move; one of the code lock subassembly 2 and the key lock subassembly 3 is from the in-process that the locking state changed to the unblock state, drives 6 removal of linkage and makes the hole of stepping down 61 align with stopper 5, and stopper 5 is portable to penetrate the hole of stepping down 61.
