Description
The utility model relates to a kind of improved mortise lock.
Pellet shot from a slingshot on the common pellet shot from a slingshot mortise lock is all adorned in one direction, and promptly tartar on the key all is in on one side, so utilize foreign matter to make technical unlocking easily.
The purpose of this utility model is to provide a kind of security performance good, simple in structure clear, easy for installation, improved mortise lock that cost is low.
The utility model is made up of locking system, fixedly connected part and key, locking system comprises lock body, lock core, vane group, blade stage clip, two symmetrical square grooves are arranged in the tapered end, six square through holes are arranged on the lock core, be used to install blade, one end of square through hole is provided with columniform blind hole, be used to install the blade stage clip, these blind holes are divided into two groups by direction and position, the compression resistance force of blade stage clip makes blade divide both direction outwards to stretch, every side's direction has three blades, and the shoulder portion of blade inserts in the lock body square groove; The key tooth flower height is consistent to the distance at blade center with the stressed limit of blade endoporus, tapered end cover and gasket ring riveting are contained on the lock body, and tapered end cover, tapered end spring are fixed between the boss of tapered end and lock body, and circlip is stuck in the circlip groove of lock core, lock core is limited in the lock body, two pin-and-holes are arranged on the lock body.
The utility model utilizes the directionality in lock core blade press spring base hole, by the blade stage clip vane group is stretched to two directions, thereby produce the both direction locking action, must there be two tartar directions to open, so the utility model is a kind of technical unlocking that is difficult for, the mortise lock that security performance is outstanding.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
The utility model is made up of locking system, fixedly connected part and key.Locking system comprises lock body (5), lock core (11), vane group (9), blade stage clip (10).Two symmetrical square grooves are arranged in the lock body (5), six square through holes are arranged on the lock core (11), be used to install blade (9), one end of square through hole is provided with columniform blind hole, be used to install blade stage clip (10), these blind holes are divided into two groups by direction and position, make vane group (9) produce the locking action of two directions.The compression resistance force of blade stage clip (10) makes blade divide both direction outwards to stretch, and each direction has three blades, and the shoulder portion of blade inserts in the lock body square groove, thereby makes lock core (11) locking, and dead bolt can not be opened.The unlatching and the transmission of this tapered end are directly finished by key.The tartar that is had on the key (2) must with lock core (11) on the vane group of adorning (9) corresponding, promptly key tooth flower height and the stressed limit of blade endoporus are consistent to the distance at blade center.Insert key (2), by tartar height control leaf position, if key is incorrect, blade one end is lower than lock core (11) cylindrical, and the other end protrudes lock core (11) cylindrical, is stuck in lock body (5) square groove, can not rotate.If key (2) is correct, the blade two ends are concordant with lock core (11) cylindrical, this moment rotatable key (2) and lock core (11), key tail drives the opening mechanism motion of dead bolt, thereby drives the dead bolt unlatching on the door or close.This tapered end is in opening process, and key only need rotate half-turn just can drive the dead bolt motion, very convenient.
Tapered end cover (3) and gasket ring (4) riveting are contained on the lock body (5), and tapered end cover (7), tapered end spring (6) are fixed between the boss of tapered end and lock body, play decoration, the effect of location.
Circlip (8) is stuck in the circlip groove of lock core, and lock core is limited in the lock body, and two pin-and-holes are arranged on the lock body, utilizes the latch that adds to pass these pin-and-holes, just tapered end can be fixed on the lock gall.
The utility model mortise lock secret key amount is fabulous, (every kind of blade can be divided into two kinds again by the endoporus direction to have in five kinds the different blade in hole site, promptly have ten kinds of blades), each lock core is equipped with six blades, so the different tooth numbers of key reach 56 promptly 15625 kinds.
In sum, the utility model tapered end has safe and reliable, compact conformation, and characteristics easy for installation can improve theftproof performance effectively.
