Description

A kind of twin-lock core cylinder lock and key thereof

Technical field

The utility model relates to a kind of lock, particularly relates to a kind of twin-lock core cylinder lock and matched key thereof.

Background technology

Aspect lockset, cylinder lock is the most widely used product always.But the cylinder lock that people generally use, no matter lock core is " one " font, " ten " font, or concentric circles, lock core is always the integral body of a rigidity.Because the pellet shot from a slingshot in the lock core can not be arranged point-blank utterly, thereby robber's utilizable energy produces the utensil (hereinafter referred to as " moving rod ") of a turning moment to lock cylinder, apply a turning moment to lock cylinder outside, thereby pellet shot from a slingshot, lock core, lock core sleeve are closely combined; And then with the utensil (below become " driving lever ") that can stir the pellet shot from a slingshot bob in lock cylinder the inside, in lock core, the pellet shot from a slingshot that is subjected to shearing force is earlier stirred up and down, under the effect of shearing force, make this group pellet shot from a slingshot be divided into one of lock core, one of lock core sleeve, thereby removed the effect of this group pellet shot from a slingshot.At this moment lock core has a small rotation again and changes under the effect of moment, produces new pellet shot from a slingshot and is subjected to shearing force, with above way it is removed again, and pellets shot from a slingshot all in lock core all are disengaged, and have so just caused to be locked under the keyless situation to be opened.

The utility model content

The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of theftproof strong, and simple in structure, go slick, production and processing convenient feasible, easy twin-lock core cylinder lock and matched key thereof be installed.

For achieving the above object, the technical solution of the utility model is as follows:

The twin-lock core cylinder lock that the utility model proposes comprises lock body, dead bolt, lock core sleeve and places rotating lock core in the lock core sleeve.Lock core and rear lock core before lock core is divided into, near key handle be preceding lock core, away from key handle is rear lock core; Preceding lock core inside is provided with preceding key, and rear lock core inside is provided with the back key.Preceding lock core can move relative to rotating with rear lock core; Preceding lock core and rear lock core junction are provided with holes pellet shot from a slingshot hole, and the part in holes pellet shot from a slingshot hole is positioned at preceding lock core, and another part is positioned at rear lock core, and the holes pellet shot from a slingshot is provided with the holes pellet shot from a slingshot in the hole, have pressed from both sides one group of holes pellet shot from a slingshot between promptly preceding lock core and the rear lock core.Because when common spring is subjected to moment of face at lock core, it will be subjected to the shearing force of lock core and lock core sleeve, its intersection point is just in time at both interface, if " driving lever " that this moment, pellet shot from a slingshot was moved up and down provokes, just can search out the position of removing self suffered shearing force one by one voluntarily, thereby remove the pin key function of pellet shot from a slingshot; And among the application, because lock core is divided into two sections of the front and back that are separated from each other by original one, lock core and rear lock core connect each other, limit mutually by the holes pellet shot from a slingshot again simultaneously, therefore lock core and rear lock core are under the effect of moment of face before, can not be subjected to direction, moment of the same size simultaneously, make the robber when pirate of the open, can't judge the order of the suffered resistance of pellet shot from a slingshot in the lock core, thereby prevented that cylinder lock is rotated unlatching after pellet shot from a slingshot is removed resistance one by one in the lock core.Lock core marble in the holes pellet shot from a slingshot hole has limited the maximum swing offset of preceding lock core and rear lock core simultaneously, has prevented to open respectively preceding lock core of rotation and rear lock core.

Described dead bolt is a U-shaped, is assembled between preceding lock core, rear lock core and the lock core sleeve; The rear lock core both sides are provided with the rear lock core lock tongue slot, the both sides of lock core before the two ends of dead bolt place through the rear lock core lock tongue slot.In the whole lock core design is to be inserted by the front end of lock core sleeve, mixes screw with the steel plate ring then and is closed in the lock core sleeve.

The cross section top of described back key is pellet shot from a slingshot free travel section, and the bottom is a circle." moving rod " that this design makes the robber use can not surmount in the free travel section of pellet shot from a slingshot, if surmounted then pellet shot from a slingshot will move upward, " driving lever " just can not stir the pellet shot from a slingshot freely-movable, and therefore the Breadth Maximum of " moving rod " can only be in above-mentioned circle; But,, also just can not pirate of the open lock so " moving rod " can not apply moment of torsion to rear lock core just because of be again a circle.Design the width d of the diameter b of described circle smaller or equal to 2 times of described pellet shot from a slingshot free travel sections, " driving lever " enters into pellet shot from a slingshot free travel section when preventing pirate of the open, just reduces to dial the space of pellet shot from a slingshot as far as possible.

The cross-sectional height of key is greater than the cross-sectional height of described back key before described; The height a that the cross-sectional height of back key equals described pellet shot from a slingshot free travel section adds the above circular diameter b.Because it is lock core both sides before placing through rear lock core that U-shaped is dialled tongue, thereby the just motion and the power transmission of the preceding lock core of control of the major function of rear lock core, itself is outwards power transmission not, therefore it self stressed little, key is as long as can satisfy the rear lock core driven rotary, and therefore key more preceding key in back narrows down.Back key narrows down can increase the intensity of rear lock core, strengthens anti-theft feature; What is more important makes the robber can not adopt " driving lever " to remove the pin key effect of pellet shot from a slingshot in the rear lock core again when producing moment of face to rear lock core, also just can't the whole cylinder lock of pirate of the open.

Before described on the lock core, the place that is provided with between dead bolt and the preceding key is provided with preceding lock core stainless steel substrates cover; On the described rear lock core, rear lock core lock tongue slot and back be provided with rear lock core stainless steel substrates cover between the key, revolves when turning 90 degrees in order to prevent rear lock core, pellet shot from a slingshot is fallen in the rear lock core lock tongue slot.

Be used to open the key of above-mentioned twin-lock core cylinder lock, stepped, be divided into key leading portion and key back segment, near key handle be the key leading portion, away from key handle is the key back segment.The key leading portion is wideer than key back segment, and promptly the cross-sectional height of key leading portion is greater than the cross-sectional height of key back segment; Key before the key leading portion correspondence, key after the key back segment correspondence.The major function of key leading portion be before removing in the lock core pellet shot from a slingshot and lock core simultaneously the moment of torsion on the key handle is passed to preceding lock core with the pin key function between the lock core sleeve, drive the capable tongue of dialling of U again and stir the interior machinery of lock body, thereby whole lock is opened through rear lock core.

In the process of normally unblanking with key, drive preceding lock core rotation by the key leading portion, drive U-shaped then and dial the tongue rotation, power transmission reaches the function of normally unblanking to lock body with this again.Because the existing lock core of preceding lock core is short, has also brought the key leading portion shorter simultaneously, makes the two in use, can bear than original bigger moment.Rear lock core is outwards power transmission not, only lock core motion before the control.

Compared with prior art, the beneficial effects of the utility model are: improve the theftproof performance of existing cylinder lock, and simple in structure, both can put in order the mode of lock separately produces and puts goods on the market, can only produce lock core, dead bolt again existing cylinder lock is replaced, cost is low, high efficiency.
