Abstract

The invention discloses a chain lock, which comprises a lock head and a bolt. The lock head includes a lock head seat, a fixing seat, a positioning groove, a lock tongue, a lock core and a casing, and the fixing seat and the positioning groove are sequentially arranged transversely. At the front end of the lock seat, the lock tongue is set on the positioning groove, the lock core is installed on the front end of the lock tongue and connected with the positioning groove, and the shell is wrapped around the fixing seat, the lock tongue and the lock core And it is connected with the lock seat. The shell is provided with a pin hole protruding from the upper part of the shell. The pin hole corresponds to the position of the dead bolt and the positioning groove respectively, and the described pin is connected to the dead bolt through the pin hole. Connect with the positioning groove. Through the above method, in the chain lock of the present invention, the bolt is completely covered inside the lock head through the bolt hole, and is not easily damaged. At the same time, the movable end of the bolt is inserted into the positioning groove, which can provide more stable positioning through the positioning groove, reducing The shaking of the movable end increases the stability of the locked chain and the ability to prevent damage.

Description

technical field [0001] The invention belongs to the field of locks, in particular to a chain lock. Background technique [0002] The chain locks that are widely used now use a chain connected to the lock body to buckle the locked object, and then the lock cylinder is closed. live purpose. [0003] However, the front end of most chain locks connects the hook and the chain through a bolt, and then locks into the lock body. The covering is poor, and the lock head or the bolt are easily damaged. In addition, there is a design that the large bolt of the lock body is inserted into the chain head, but the front end of the chain head will shake, the structure is exposed, and it is also easy to be damaged. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a chain lock. The shell is provided with a pin hole protruding from the upper part of the shell. The pin is completely covered inside the lock head through the pin hole...
