Zipper coded lock

Abstract

The invention relates to a zipper coded lock. Each password wheel component is vertically and transversely distributed in a lock cylinder containing cavity in parallel; the password wheels are sleeved on an inner wheel; an elastic device for pressing and linking the inner wheel and the password wheels are arranged at the axial end of the inner wheel; a code changing mechanism is arranged at the other axial end of the inner wheel; the code changing mechanism comprises code changing strips and a number adjusting dialing block assembled in the lock cylinder containing cavity in a sliding way; the number adjusting dialing block is in linked connection with the code changing strip; the code changing strips are arranged along the arrangement direction of the password wheels, and are positioned at the other axial end, opposite to one end of the elastic device, of the inner wheel; when a password wheel lock mechanism is in a unlocking state, the code changing strip can push the inner wheel to axially displace along the inner wheel and the inner wheel is separated from the password wheels, so that the password wheel lock mechanism is in a code changing state; and when the password wheel lock mechanism is in a locking state, a sliding plate forms limiting locking on the sliding direction of the code changing strips to the code changing strips. Compared with the prior art, the coded lock has the advantages of simple structure, small size, convenience in code changing operation, and stable and reliable code changing.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a zipper combination lock applied to a bag with a zipper device for locking the zipper. Background technique [0002] At present, the zipper combination locks used on luggage mainly include the arrangement of combination wheels in vertical parallel series and the arrangement of combination wheels in horizontal parallel arrangement. The vertical parallel tandem zipper lock adopts the inner wheel set on the rotating shaft, and the code wheel is set on the inner wheel. On the one hand, the thickness of the zipper lock is increased, and the overall volume of the zipper lock is large. On the other hand, there are many matching parts in the lock mechanism. ,complex structure. [0003] Such as figure 1 As shown, the side-by-side straight-line zipper lock is compared with the vertical tandem zipper lock. The end face of the combination wheel is provided with convex points, and the end fa...

Problems solved by technology

[0006] By adopting the above-mentioned technical scheme, the combination wheel lock components are vertically and horizontally arranged in parallel, and the combination wheel is set on the inner wheel, so that not only the combination numbers can be set on the circumferential surface of the combination wheel, but also the inner wheel can be arranged on both sides in the axial direction. The elastic device and the number changing bar of the code changing mechanism can be respectively set at the end positions, and the elastic device ensures that the combination wheel and the inner wheel are connected reliably in normal use; and the number changing bar is arranged at one end of the inner wheel axis, The arrangement direction of the components is set, that is, the number change bar is perpendicular to the axial direction of the inner wheel. When the code wheel lock mechanism is in the unlocked state, the number change bar can simultaneously push the inner wheels of each code wheel assembly to move axially, and then separate from the code wheel to release the lock. The inner wheel and the code wheel are limited in the circumferential direction, and the code wheel can be rotated freely to change the code. After the code change is successful, the code change mechanism is reset, and under the action of the elastic device, the code wheel and the inner wheel are reliably connected again; During the coding process, the password wheel is not interfered by the inner wheel, has no resistance, and the code changing operation is simple, easy, convenient and stable and reliable. It can adopt friction transmission by setting bumps and grooves between the two ends, and the code change can only be completed by forcibly turning the code wheel to break through the friction between it and the inner wheel; the defects caused by the normal unlocking operation , the elastic device ensures the reliable linkage connection between the combination wheel and the inner wheel, and the transmission is stable and reliable, which solves the problem of reliable linkage between the combination wheel and the inner wheel when the traditional combination wheel lock components are arranged horizontally and side by side. As a result, the reliability and stability of the password wheel and the inner wheel transmission are not enough.
