Problems solved by technology

In addition, when indoors, peepers can see the password by pulling out the lock cylinder, and can even re-insert the real code key to easily change the previously set password. Therefore, this scheme still has the defect that the security is not good enough

Embodiment Construction

[0017] A preferred embodiment of a circular mechanical combination lock cylinder of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 , image 3 As shown, a circular mechanical combination lock cylinder includes a label plate 1, a guide plate 10, a bracket plate 11, an activation plate 12, a positioning mechanism, a casing 15, a combination key 8, and also includes a rotation setting button 28 and a pushing device 30.

[0019] The center of the labeling plate 1, the guide plate 10 and the support plate 11 is connected by the guide column 5, and a round rod is fixed at the center of the circle of the starting plate 12, and the round rod is inserted into the cylinder protruding from the support plate 11. The starting plate 12 rotates relative to the support plate 11 with the round bar as the center of circle. There are many rivets 24 riveted on the support plate 11, and the described star...

Abstract

The invention relates to a round coded lock cylinder. A labeled plate, a guide plate, a bracket plate and a starting plate are all round. The starting plate comprises a round bottom plate, an annular side wall and an annular cornice. The starting plate is also provided with an extending end which extends out of a shell when the starting plate is arranged. A rotary setting button is arranged on the surface of the shell, a push device is connected with the rotary setting button, and a pull rod connected with the push device is attached with the starting plate together. A code key is of a laminate structure, the middle opening of the code key is embedded with a key offsetting spring, the upper part and the lower part of the code key are provided with grooves, the surface of the code key is marked with numbers or letters, the working end face of the code key with an inclined surface is an actual code key, the working inclined surface of the actual code key has a width change according to the size of the marked numbers or letters, and the working end face without the inclined surface is a null key. The working end of the code key is riveted with a rectangular conversion sheet which can move towards the two ends. The round coded lock cylinder has the characteristics of small volume, free setting of the digit of the code, large code capacity and good confidentiality.

Description

technical field [0001] The invention belongs to the technical field of locks, and in particular relates to an intelligent mechanical combination lock cylinder. Background technique [0002] Combination lock is a kind of convenient and reliable lockset. In the prior art, combination locks are divided into electronic key combination locks and mechanical key combination locks. Electronic key combination locks have a large number of passwords, but are not moisture-proof, acid-proof, and waterproof. Although mechanical key combination locks can be moisture-proof, acid-proof, and waterproof, The amount of codes is far less than that of electronic key combination locks. In the prior art, although the mechanical combination lock cylinder is convenient to cooperate with the existing lockset, there are still many defects in the mechanical combination lock cylinder. In the prior art, the combination lock core is mostly square structure, the volume is relatively large, and the volume ...
