Abstract

The utility model discloses an anti-theft lock body. The anti-theft lock body is composed of a main lock tongue component, an inclined tongue component, an upper pull rod, a lower pull rod, a reverse lock tongue component, an auxiliary lock point component and the like. The lock body is core-inserting-type and locking points in a three-direction mode. The anti-theft lock body is characterized in that when a door is closed, the lock body firstly locks the door through an inclined tongue head, safety of the main lock tongue is opened by rotating or pressing a safety shifting block, a main lock tongue board of the main lock tongue pops out automatically from the lock body under the combined effect of a spring and elasticity of the spring, the upper pull rod and the lower pull rod are driven to pop out simultaneously through a pin shaft on the main lock tongue board, and a stirring piece of the auxiliary lock point is driven by the upper pull rod and the lower pull rod to stir the auxiliary lock point on the lateral face, and therefore three-direction locking is achieved. When a lock is opened, a key is used for rotating a hand gear on the lock head to drive a lever to swing, one end of the lever presses a connecting pin shaft of a coupler to enable a square hole in a connecting sleeve of the coupler to be connected with a lever handle square rod on a lock front panel, the coupler can be rotated by moving a lever handle, a cam is fixed on the lower portion of the coupler, and two cam faces on the cam act simultaneously and respectively on a stirring point on the main lock tongue board and an inclined tongue stirring rod to drive the inclined tongue component to enable the main lock tongue, the inclined tongue, the upper pull rod, the lower pull rod and the auxiliary lock point to withdraw inward, and therefore the lock is opened. The anti-theft lock body has the advantages that when a user often goes in and out the door at home, during door closing, the inclined tongue firstly locks the door, the main lock tongue, the upper pull rod and the lower pull rod lock the point, and when necessary, the safety shifting block which controls the safety is used for controlling the main lock tongue to pop out automatically so as to reduce use frequency of the main lock tongue and prolong service life of the lock body. A traditional method of opening the lock with the key during door opening is changed, and the lever handle is adopted to open the lock, and therefore the problem of using the key to open an automatic lock body is inflexible and the like is solved, and old people, children, disabled people and the like open the door conveniently.

Description

Safety lock body

Technical field:

The utility model relates to a kind of safety lock body of novelty, belongs to the safety precaution series products.

Technical background:

Existing lock probably is divided into two class formation lock bodies, the one, traditional mechanical lock, its mode of locking a door is that lock body inclined tongue is locked a door first, the master lock tongue and up and down lock point be to lock and unblank with key.The 2nd, the automatic locking body structure, it is to have to bump a little to trigger the master lock tongue and lock up and down point at the lock body structure of spring force effect automatic spring.Former structure is reliable, stable, but owing to locking and unblanking all to need the suction key to realize, trouble uses inconvenience.The latter's advantage is easy to use, all lock points automatically lock when locking a door, and shortcoming is that all lock points automatically lock simultaneously when locking a door, the lock point out the time as easy as rolling off a log wiping frame or mistake can break lock point and doorframe when ejecting, and key operated very heavy, child old man opens inconvenience.

Summary of the invention:

The purpose of this utility model aims to provide a kind of core-inset type Three-bearing latch-up structure safety lock body to the security door industry.

The utility model proposes technical solution for the deficiency of above-mentioned technology: the one, at closing time, latch bolt is locked a door first as traditional mechanical lock, the 2nd, by turn or press insurance shifting block the insurance of master lock tongue is opened, the master lock tongue is outwards ejected by lock body under the elastic force acting in conjunction of two springs, drive simultaneously upper and lower pull bar and reach up and down secondary lock point, realize the Three-bearing locking.The 3rd, will change the mode of tradition with key operated lockset, adopt handle to open lockset, solve the key operated very heavy problem of automatic lock body, the key here just control connects the effect that handle is opened lockset.The utility model has the advantages that; When the people was in frequent inlet/outlet at ordinary times, the latch bolt of closing the door was locked a door first, and master lock tongue and Tiandi lock point up and down in case of necessity, are controlled it by the insurance shifting block of a control insurance and automatically outwards ejected, and reduce master lock tongue frequency of utilization, improved lock body application life.Opening the door changes tradition with the mode of key operated lockset, adopts handle unlatching lockset, can solve the key operated problem such as very heavy of automatic lock body, makes things convenient for old man, child and disabled person etc. to open the door.

Description of drawings:

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1, Fig. 2, Fig. 3 are and open elevation behind the lock cover;
