Description

Pin tumbler lock

The utility model relates to lock, key, particularly the lock of specific use.

At present, various pin tumbler lockes, of a great variety, but mainly be applicable to have install on the certain thickness door be divided into lock body and tapered end two-part multi-functional (as two insurances, three insurances) door lock, these pin tumbler lockes, how to make precision with stamping parts or iron sheet spare, intensity is not high, and is insecure, yielding, and because function is many, complex structure is so easily break down, even akinesia, this door lock then can not use when for example the fully closed door of individual layer steel plate (as the gate of factory) waits on the door that need be installed in thinner thickness, and position that must the dress lock thickeies, could the lock dress is firm, very inconvenient.

The purpose of this utility model provides a kind of tapered end and lock body is integrated, simple in structure firmly, be not subjected to the thickness effect of door during installation and the pin tumbler lock that can directly install.

The purpose of this utility model realizes by following technical scheme, pin tumbler lock has lock body, it is characterized in that also having keeper and spring in lock body, this spring makes the tongue retraction lock body of keeper, the other end of keeper has stopper slot and the pin on lock body, can pin the pellet shot from a slingshot and the marble spring of keeper in the keeper in addition, also has the pellet shot from a slingshot and the marble spring of core and locking core in the lock body, crescent is arranged on the core, and the pellet shot from a slingshot of said locking keeper stretches into this crescent.

Said keeper has axial hole, and the spring that dead bolt is housed in the hole and dead bolt is ejected is fixed with pin on the dead bolt, the groove that makes pin stretch out lock body is arranged on lock body and the keeper.

Said keeper has axial hole, and the spring that dead bolt is housed in the hole and dead bolt is ejected is fixed with pin on the dead bolt, and keeper has the groove that pin slides therein.

Below, in conjunction with the accompanying drawings and embodiments pin tumbler lock of the present utility model is explained in detail.
