Abstract

The utility model discloses a cylinder lock. The utility model aims to solve the problem that a Chinese patent named a cylinder lock with a patent number of ZL99126675.7 has the defect of low cipher key amount because a key hole orifice is arranged on the outer edge of a lock core and the permutation of a marble group is limited. Under the condition of maintaining the diameter of a lock body unchanged, the cylinder lock provided by the utility model has the key hole orifice arranged on the wall of a counter bore on the end face of the lock body; the tail end of a part of the key having bits is positioned and connected with a rotating shaft in a key box, and an open-ended structure is arranged on the outer edge of the key box. Thus, the permutation curve of the marble group on an interface between the lock body and the lock core can be distributed at positions beyond the diameter of the outer edge of the key box, thereby increasing the permutation number of the marble group, and consequently improving the cipher key amount.

Description

A kind of cylinder lock

Affiliated technical field

The utility model relates to a kind of lock, a kind of specifically cylinder lock.

Background technology

The cylinder lock of the bolt-type structure that continuity was produced, used hundreds of years, simple in structure with it, the size of key height, irreplaceable advantage such as the manufacturing process maturation and the scope of application are wide makes it keep higher occupation rate in lockset market always.Yet existing cylinder lock also ubiquity and is had measurability, easily by the shortcoming of technical unlocking.The patent No. is: 99126675.7 of ZL are called: a kind of Chinese patent of cylinder lock, adopt the pellet shot from a slingshot group to press the curve form arrangement along lock body and lock core end face; Key shape is corresponding with the alignment curve shape of pellet shot from a slingshot group; Open on the outer rim of lock core in the key aperture; The shape of keyhole is corresponding with the alignment curve shape of pellet shot from a slingshot group; Key is the technical scheme of high elastic modulus alloy spare, has solved the above-mentioned measurability problem that cylinder lock exists.According to this patent document record, as one of modified of this patent of invention, adopted following technical scheme: key positioner is connected in the key case, the position in the key aperture on the position of one end in key case of key band tartar part and the lock core outer rim is corresponding, lock body has an end in key aperture that one counterbore is arranged towards lock core, the part that lock core has the key aperture is contained in this counterbore, there is suitable gap that key case is inserted between this counterbore and the lock core outer rim, rotate, key is to enter keyhole by the screw key box, lock core marble is pushed up the interface place of lock core and lock body, continue the screw key box, make it execute moment of torsion, drive lock core and rotate with respect to lock body in lock core.Yet the lock body end face counterbore of this technical scheme and key case define the radially chi of the lock core part that is contained, and then define the number of the arrangement of pellet shot from a slingshot group on the lock core end face.Under the certain situation of lock body diameter, adopt the cylinder lock of technique scheme to have the low shortcoming of size of key.

Summary of the invention

In order to solve the low shortcoming of above-mentioned prior art size of key, the technical solution of the utility model is: on the end face of lock body away from an end of lock core a counterbore is arranged, the keyhole that has on this counterbore hole wall in a key aperture and the lock body communicates,

A kind of cylinder lock of the utility model has adopted the key aperture to open at lock body away from the structure on the hole wall of the counterbore on the lock core one end end face, the end that key has the part of tartar is located by connecting on the interior axis of rotation of a key case, the part that key has tartar is coiled in the key case, has an opening on this key case outer rim, the position in the key aperture on the position of this opening and the lock body counterbore wall is corresponding, this opening and key have between the part of tartar suitable gap are arranged, rotate axis of rotation, can make this key have the tartar part from front end, by the key aperture, enter the keyhole in the lock body.In addition, a kind of cylinder lock of the utility model has adopted has a mandrel in the lock body counterbore, this mandrel passes lock body fixedlys connected with lock core, and suitable gap is arranged between mandrel and the lock body, can make mandrel drive the structure of lock core, realize moment of torsion propagation function lock core with respect to the lock body rotation.

Under the constant situation of lock body diameter, when lock core is realized the moment of torsion propagation function, open on the hole wall of lock body end face counterbore in the above-mentioned key aperture that a kind of cylinder lock of the utility model adopts, the end that key has the part of tartar is located by connecting on the interior axis of rotation of a key case, the structure that has an opening on the key case outer rim, the alignment curve on lock body and the lock core interface make the pellet shot from a slingshot group on can be distributed in position greater than key case external profile diameter size, the quantity that the pellet shot from a slingshot group is arranged, quite adopt lock body to contain the part of lock core, the structure that open on the lock core outer rim in the key aperture increases to some extent.

With the patent No. be: 99126675.7 of ZL are called: a kind of screw key box of Chinese patent of cylinder lock, drive the keyhole that the key tooth flower part directly enters lock core, and then the technical scheme that drives the lock core rotation is compared, the technique scheme of a kind of cylinder lock of the utility model, under the constant situation of lock body diameter, when lock core is realized the moment of torsion propagation function, obtain more pellet shot from a slingshot group arrangement position than prior art, size of key also improves thereupon.

The key of a kind of cylinder lock of the utility model has the end of the part of tartar, with being located by connecting of axis of rotation in the key case, be one rectangle gap to be arranged by the end that key has a part of tartar, have on the outer rim of axis of rotation one with the corresponding L type of rectangle gap gap, this L type gap and described rectangle gap grafting structure realized.

The key of a kind of cylinder lock of the utility model applies the function of moment of torsion to lock core, be existing in the following manner: described mandrel has the groove that prolongs radially at least on the end face of an end of key case, axis of rotation axle center in the described key case has a centre bore, there are a key axle and centre bore to be slidingly matched in this centre bore, have at least on the end face of described key axle near an end of lock body and prolong radially and the corresponding projection of groove, the key axle is fixedlyed connected with the shank of the key away from an end of lock body.
