The purpose of this utility model is to provide a kind of technical unlocking, mortise lock that security performance is outstanding of being difficult for.
The utility model is made up of locking system, transmission system and fixedly connected part, locking system comprises lock body, lock core, vane group, blade stage clip, the tapered end cover riveting is contained on the lock body, two symmetrical square grooves are arranged in the lock body, six square through holes are arranged on the lock core, be used to install vane group, an 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; Transmission system comprises key, lock core, elastic cylindrical pin, rotary sleeve, drive plate, the key tooth flower height is consistent to the distance at blade center with the stressed limit of blade endoporus, elastic cylindrical pin is fixed on the afterbody of lock core, and rotary sleeve is enclosed within on the lock core, drives plate and is contained in the square hole of rotary sleeve; Fixedly connected part comprises tapered end pin, tapping screw and Lock cylinder cover, and Lock cylinder cover is fixed on the lock body afterbody with tapping screw.
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 produces the both direction locking action, must have two tartar directions to open.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
Fig. 2 is the utility model cross-sectional view.
The utility model is made up of locking system, transmission system and fixedly connected part.Locking system comprises lock body (4), lock core (5), vane group (6), blade stage clip (7).Two symmetrical square grooves are arranged in the lock body (4), six square through holes are arranged on the lock core (5), be used to install vane group (6), one end of square through hole is provided with columniform blind hole, be used to install blade stage clip (7), these blind holes are divided into two groups by direction and position, make vane group (6) produce the locking action of two directions.The compression resistance force of blade stage clip (7) 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 (5) locking, and dead bolt can not be opened.Transmission system comprises key (2), lock core (5), elastic cylindrical pin (8), rotary sleeve (9), drives plate (12) (single head or double end).The tartar that is had on the key (2) must with lock core (5) on the vane group of adorning (6) 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 (5) cylindrical, and the other end protrudes lock core (5) cylindrical, is stuck in lock body (4) square groove, can not rotate.If key (2) is correct, the blade two ends are concordant with lock core (5) cylindrical, turn key (2) and lock core (5) this moment, stir rotary sleeve (9) by the elastic cylindrical pin (8) that is fixed on lock core (5) afterbody, be contained in the interior drive plate (12) of rotary sleeve (9) square hole also along with rotation, thereby drive the dead bolt motion on the door.This tapered end is in opening process, and key only need rotate half-turn just can drive the dead bolt motion, very convenient.Drive plate (12) and divide single head to drive plate and double end drives two kinds of plates, single head drives plate and is used for adorning outdoors tapered end, and the situation of dress knob in the door, double end drive the situation that plate is all adorned tapered end inside and outside then being used for.
Tapered end cover (3) riveting is contained on the lock body (4), plays the effect of decoration, location.
Lock cylinder cover (10) is fixed on lock body (4) afterbody with tapping screw (1), has fixed lock core (5), rotary sleeve (9), has driven the moving position of plate (12).
Tapered end pin (11) is fixed on the door tapered end with the screw that adds.
The utility model mortise lock secret key amount is fabulous, has the different blade (every kind of blade can be divided into two kinds again by the endoporus direction, promptly has ten kinds of blades) in hole site in five kinds, and each lock core is equipped with six blades, so the different tooth numbers of key reach 5
6Promptly 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.
