Abstract

The present invention is a kind of double pin tumbler lock and key thereof that is adapted to be mounted within on the thin wing fan.Its main feature is to be drilled with two row's pellet shot from a slingshot holes on tapered end and lock core axisymmetrically, is shaped on a straight-through key groove hole and a shared straight locating slot in the lock core, has only half position to be drilled with the pellet shot from a slingshot hole on the length direction of lock core; Tabular key is milled with trough on its two sides, and there is the tooth that equates with diagonal on both sides, and tooth quantity is Duoed one times than the pellet shot from a slingshot hole number.Profile thin thickness of the present invention, forward and reverse the unblanking of energy, safety, good reliability are specially adapted to be installed on the iron gate and balcony door outside the room, worker-house.

Description

Double cylinder lock and key thereof

The present invention relates to lockset, is a kind of pin tumbler lock that is suitable for being installed on the thin wing fan.

Modern apartment, worker-house development for increasing housing safety, often refill one iron gate rapidly outdoors in the chamber, refill a lockset on the iron gate, or also adorn a lockset on balcony door.But standard steel casement door, iron gate are all thinner, and the thickness of existing common spring door lock, insurance pin tumbler lock is all thicker, so the pin tumbler lock that will install in the market on steel, iron is very bothersome, and, if the lockset that can both lock, open inside and outside needing to install, then the pin tumbler lock with double end must be installed, thickness is thicker, is difficult to install.It is " two sides teeth key and double cylinder lock " utility model patent of 87200441 that the Chinese patent communique on April 20th, 1988 was announced a kind of application number.Its main feature is the corresponding respectively two row's pellet shot from a slingshot holes that have a row or symmetry on lock core and the tapered end, has the right angle type keyhole on the lock core; The key that is cooperated is to be the symmetrical keys of initial point with the center, cross section.Though this double cylinder lock can be done thinnerly, can not inside and outside unblank, key such as two-sided use are the advantages of square multiple of general lock with regard to the safety factor that has lost lock, the key single face uses, and can bring certain trouble to the user.And the lockhole of the symmetry of this double cylinder lock has certain degree of difficulty on the technology opening system.

The objective of the invention is to be fit to be installed on room iron gate or the balcony door in order to provide a kind of safety factor higher, and the double cylinder lock of unblanking inside and outside the energy.

For achieving the above object, the present invention is designed to its cross-sectional shape to the tapered end of tapered end and is oval shape structure, and the lock core hole that is positioned at the tapered end center axially is drilled with two row's pellet shot from a slingshot holes by the long axis direction of oval tee section still for cylindrical symmetrically along tapered end; Be contained on the lock cylinder in the lock cylinder hole of tapered end, axially be drilled with two row corresponding pellet shot from a slingshot holes, pellet shot from a slingshot hole on two rows and the tapered end radially symmetrically along it by circular cross-section, have the symmetrical keys slotted eye of a perforation on the lock core vertically from the end face center, be shaped on a shared straight locating slot in the middle of the hole, the length of lock core is the twice of row's pellet shot from a slingshot hole site length.Be to have only half position to have the pellet shot from a slingshot hole on the lock core, also have half position to be not open the pellet shot from a slingshot hole.

The key that cooperates above-mentioned tapered end is still a kind of tabular shape key, but is milled with and the corresponding trough of lock core key slotted eye on its two sides, and both sides are milled with the tooth that equates with diagonal, and tooth quantity is Duoed one times than the pellet shot from a slingshot hole number.

By above-mentioned tapered end and Key structure as seen, it has axisymmetric two row's pellet shot from a slingshot holes, and under the condition that is reaching the existing same security requirement of cylinder lock at least, the quantity in every row's pellet shot from a slingshot hole just can reduce, and this means the tapered end slimming; In addition, the pellet shot from a slingshot that this tapered end can install in two row's pellet shot from a slingshot holes is under the asymmetric condition, still unblank with a key two sides, no matter promptly unblank outdoor, still unblank indoor, all only utilize same marble hole structure, when at forward (outdoor) when unblanking, one group of profile of tooth at key rear portion is matched with the pellet shot from a slingshot hole, and oppositely (indoor) makes one group of tooth of key front portion match with the pellet shot from a slingshot hole when unblanking.

Description of drawings:

Fig. 1 is the structure sectional view of tapered end part of the present invention.

Fig. 2 is the structural representation of lock body part of the present invention.

Embodiments of the invention as shown in drawings.See that by Fig. 1 the tapered end part of cylinder lock of the present invention is made of lock core 1, tapered end 2, marble spring 6, pellet shot from a

slingshot

7,8,9,10, plate pin 4 and lock core face shield 5.Lock core 1 is a cylinder that has omoplate, be drilled with the double pellet shot from a slingshot hole, 6 hole that amounts on it symmetrically, wherein be fitted with pellet shot from a slingshot 10, have the symmetrical keys slotted eye of a perforation on the lock core 1 from the end face center vertically, be shaped on a shared straight locating slot in the middle of the hole, key 11 is cooperated wherein; Have only on the length of lock core 1 and have the pellet shot from a slingshot hole on half position.It is the oval cylinder that tapered end 2 is designed to exterior cross-section, the center is drilled with the lock core hole of an assembling lock core 1, inwardly straight-through lock core hole is drilled with two rows 6 and the corresponding pellet shot from a slingshot of lock core marble hole hole altogether symmetrically on the arc-shaped surface of tapered end 2 long axis directions, and pellet shot from a

slingshot

7,8,9 and spring 6 are housed in the hole.After assembling pellet shot from a slingshot and spring, the hole on the arc-shaped surface is shut with blocking 3.Plate pin 4 is sleeved on the afterbody of lock core 1, and with screw that it is fastening, and then it can steadily turn round with lock core 1.Again at lock core 1 tail end close-fitting one ornamental lock core face shield.

See that by Fig. 2 lock body part of the present invention comprises lock body shell 19, combination cylinder tongue 13, lock cover 12 drags body 15, round pin 14, latch plate 23, reference column 20,22 and torsion spring 18.Lock body shell 19 is box bodies that a rectangular one side has three dead bolt circular holes, be equipped with in it and drag body 15, drag three cylinder shape lock tongues 13 of parallel riveted joint on the body 15, drag the lead of body 15 move left and right with body reference column 20 conducts of dragging of lock body shell 19 riveted joints, latch plate 23 is contained on the latch plate reference column 22 of riveting with lock body shell 19, and the chute 24 on the latch plate 23 defines the position of dragging body 15 to move.

From above-mentioned lock body structure as seen, the present invention's lock also has the other advantage: lock body part has only lock body shell and cover plate, connects firmly three kinds of major parts such as latch plate that drag body and restriction to drag body to move of dead bolt, and the part of this cylinder lock is reduced; And dead bolt is made with several parallel round steel, and technology has been saved raw material simply again, and the cost of this lock is reduced.
