Locking structure of axial cylinder

Abstract

The invention discloses a lock structure with axial cylinders, comprising a lock body. A lock core is arranged inside the lock body; a key inserted in the lock core is matched with the lock core; the lower end of the key is provided with a bolt shaft; the bolt shaft is provided with four a vertical surface body with sides in regular layout, wherein at least two sides of the vertical surface body are provided with at least two rows of cylinder holes; the middle of the lock core is provided with a lock hole which can be matched with the bolt shaft; the inner circle of the lock core is provided with an inner side body which can be matched with the vertical surface body, and at least two sides of the inner side body are uniformly provided with at least two rows of lock core cylinders; the lock core cylinders are matched with the cylinder holes; the layout of the cylinder is between three and seven rows; the total quantity of the cylinders can reach 28 at most; the mutual opening rate of the locks of the same species is lowered by utilizing the probability theory. The standardized design of the lock core can ensure the interchangeability with other lock cores, thereby the lock structure is convenient to replace and wide in application scope. The hollow type quadrangular key bolt shaft is good in positioning property, more convenient to operate and longer in life span. The lock structure is molded through dies, thereby improving production benefit.

Description

technical field [0001] The invention relates to the technical field of pin locks, in particular to an axial pin lock structure. Background technique [0002] As early as ancient times, locks were common; in modern times, locks are still necessary items for people to live and work at home. With locks, more important documents and items can be kept safely, so a lock with better anti-theft performance is what people are after. [0003] With the continuous development of science and technology, the anti-theft performance of the locks we use has been fully developed and improved. Now there are many types of locks. As far as the common pin locks are concerned, there are currently locks with better performance in the market, such as Patent No. ZL200520116507.X is a Chinese utility model patent "Pinner Lock with Axial Rotary Pin Hole" (Notice No. CN2830584Y); the lock cylinder chamber of the lock cylinder has a guide groove, and the guide groove of the cover and the lock body The ...
