Idling blade lock cylinder assembly suitable for linear key and key thereof

Abstract

The invention discloses an idling blade lock cylinder assembly suitable for a linear key and the key thereof. The lock cylinder assembly comprises a number piece sleeve, number pieces and spacers. A special-shaped through hole is formed in the middle of each number piece, multiple stages of annular stepped tooth grooves are formed in each special-shaped through hole, and only one tooth groove used for unlocking exists in all the tooth grooves. A number piece groove is formed in the outer edge of each number piece, and when the tooth grooves used for unlocking on the number pieces rotate at the same time and are located at the same position, all the number piece grooves are aligned. The key comprises a key head and a key handle, and multiple stages of vertical teeth are arranged on one side edge of the key head. The teeth can be matched with the tooth grooves used for unlocking when the key head rotates. The lock cylinder assembly and the key not only can reduce the mutual opening rate, but also have the advantages that the lock cylinder assembly is not liable to be damaged by violent screwing, the structural stability is high, the key can be conveniently inserted, machining is convenient, the key can adapt to occasions with shorter lock cylinders and requirements on the number of teeth, and the key can be smoothly rotated.

Description

technical field [0001] The invention relates to a lockset suitable for a key, in particular to an idle-rotating blade lock cylinder assembly and a key suitable for a key. Background technique [0002] At present, the common one-piece key on the market generally has a tumbler lock cylinder as its applicable lock cylinder. Because the key shape of the one-piece key is simple and the tooth pattern processing is more convenient, it is very popular among users. The one-word key matches each marble through the tooth flower pits of different heights distributed on one or both sides of the key, so that each marble is in a suitable position, so that the lock cylinder can be rotated and unlocked; in order to make the key more conveniently inserted into the lock cylinder, Each dent will have a certain taper, resulting in a transition section between adjacent dents, and a distance between adjacent dents and marbles, resulting in effective dents within a certain length The number of mar...

AI Technical Summary

Problems solved by technology

The one-word key matches each marble through the tooth flower pits of different heights distributed on one or both sides of the key, so that each marble is in a suitable position, so that the lock cylinder can be rotated and unlocked; in order to make the key more conveniently inserted into the lock cylinder, Each dent will have a certain taper, resulting in a transition section between adjacent dents, and a distance between adjacent dents and marbles, resulting in effective dents within a certain length The number of marbles and marbles is small, and the number of arrangements and combinations of tooth flower pits is limited, which is prone to mutual opening; and the conventional pin lock cylinder cannot realize idling, and is easily damaged by violent twisting; and the one-word key cannot be directly transferred to In the blade lock cylinder that can be idling

Therefore, the existing locks suitable for one-word keys have the problems of being easy to open each other and being easily damaged by violent twisting.
