Description
Technical field
The present invention relates to lockset manufacturing technology field, especially a kind of easy-to-dismount mechanical lock.
Background technology
Lock be it is a kind of be widely used in antitheft and secrecy instrument, it is a kind of in history to be locked into changing for another kind of more advanced lock
In generation, all experienced the century-old time.From the easy-to-dismount mechanical lock of pellet of the cylindrical lock pin of American L Yales invention in 1848
So far, as long as technique has continued to use 165 years, but the broken lock of explosion-proof power and the broken lock of professional technique are indifferent;In order to improve
Anti-theft feature and secrecy dynamics, in lock industry, people make great efforts to create electronic lock, smart lock, coded lock etc., and these locks are made
High price is expensive, and is broken and is not easily repaired, and ordinary people can not accept.Then, people are still in addition excellent to the lock of L Yales invention
Change, but also simply take time in new, complicated aspect, so that the key technology of the lock core and lock body of major part cannot
Upgrading, develops into overlength lock core from short lock core, increases to two or more lock core, the i.e. circle hole shape in lock core body from a lock core and locks
It is provided with core bore in which and is provided with the internal cylinder of keyhole, the bullet of insertion keyhole and internal cylinder lateral surface is provided with internal cylinder
Sub-aperture, is provided with lock core body and the one-to-one marble hole of the marble hole of internal cylinder, and in internal cylinder and lock core body, each is right
It is mounted on two cylinder-shaped marbles, and one is provided with the marble hole of outer lock core acting on pellet in the marble hole for connecing
Spring, when in the keyhole of institute bitting insertion internal cylinder, the different teeth of height are set on the key just by keyhole
The outer end of pellet be driven in the hole face that internal cylinder and lock core body are engaged, allow internal cylinder relative to lock core body rotational band
Dynamic lockset is unlocked;When institute's bitting is exited in internal cylinder or illegal key insertion internal cylinder keyhole, due in marble hole
Spring effect, prevent the composition surface of two pellets in each marble hole from just all align in lock core body and internal cylinder
Composition surface, and in causing at least one pellet to be stuck in this composition surface, realize the sealed of lock core body and internal cylinder, although so
Lock crack probability difficulty increase, but, internal cylinder put into lock core body in when, it is necessary to use fixture block or jump ring fixed
Internal cylinder, such lock parts are various, and manufacture is complicated, cause high cost, and it is difficult to keep in repair, and mount and dismount all relatively difficult.
The fixed form of mechanical lock of today, is to arrange screw fixed mount in mechanical lock core body both sides, then little using two
Screw is fixed on mechanical lock core body on lock body by screw fixed mount, in this fixed form, needs operator's screw
Knife stretches into inside lock body to install or remove mechanical lock, very inconvenient, and during installation or removal, Screw easily falls
Fall inside lock body, be that the use of lockset is made troubles.
The content of the invention
It is strong that problem to be solved by this invention is to provide a kind of not only antitheft performance, parts are few and aspect is installed and
