Combination lock structure to prevent technical opening

Abstract

The invention discloses a combination lock structure that prevents technical opening. The lock body is sequentially provided with a number of T-shaped combination wheel accommodation grooves connected in series in the axial direction. The window of the T-shaped cipher wheel accommodation groove is exposed separately. The inner cipher wheel is axially slid and inserted in the outer cipher wheel. There is a raised structure on the outside of the inner cipher wheel, and the raised structure stops at one end of the T-shaped cipher wheel accommodation groove. , One end of the T-shaped cipher wheel accommodation groove is provided with an axial concave slideway, the convex structure of the inner cipher wheel can enter the concave slideway, and one end of the lock ring can slide axially to realize the lock ring and the inner cipher wheel Circumferential stop connection, the other end of the lock ring can be inserted into the lock hole of the lock body, and the feeder in the lock body can keep the other end of the lock ring always moving away from the outside of the lock body. The present invention greatly improves the technology of unlocking. Great difficulty, to ensure the safe use of combination locks.

Description

technical field [0001] The invention relates to a combination lock head, in particular to a combination lock structure preventing technical opening. Background technique [0002] The combination wheel of the conventional side-opening combination padlock can be rotated in the locked state to realize the unlocking action. At this time, the lock ring is pulled and the outer combination wheel is rotated. During the rotation of the outer combination wheel, the inner combination wheel directly contacts the lock ring or the central shaft. When the opening slot of the inner combination wheel is just in contact with the lock ring or the card point of the central shaft, a hand feeling will be formed. Experienced unlockers usually find the opening slot of the inner combination wheel, resulting in the combination being cracked and the lock being opened. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a combination lock ...
