Abstract

The utility model discloses a door lock allowing lock cylinder replacement. The door lock allowing lock cylinder replacement comprises a lock body and a left casing and a right casing which cover two sides of the lock body; lock cylinder holes which are for an internal lock cylinder and an external lock cylinder to insert are formed in the left casing and the right casing respectively; a cantilever which is adjusted to slide vertically through an adjusting device respectively extent out from the two sides of the lock body; clamping plates are fixed on the cantilevers; the upper surface of the lock cylinder is at least provided with a clamping groove; the clamping plates are clamped inside the clamping groove in a downward matching mode. The door lock allowing lock cylinder replacement has the advantages of allowing independent replacement of the internal lock cylinder or the external lock cylinder and enabling lock cylinder replacement to be convenient.

Description

The door lock of replaceable core

Technical field

The utility model relates to door lock, especially relates to a kind of door lock that can change separately internal cylinder or outer lock core and can be convenient for changing lock core.

Background technology

Traditional mortise door lock is that a long lock core is through whole lock body, this structure is in the time of house to let, because key being given to mechanism of letting agency, after moving in, lessee just must change door lock or lock core, this long lock core replacement cost is high, while once renting a house on carrying out, change again, will cause like this waste simultaneously.

Utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of door lock that can change separately internal cylinder or outer lock core and can be convenient for changing lock core.

The utility model is realized by following technical measures, a kind of door lock of replaceable core, include lock body, cover left shell and right shell two of lock bodies, in described left shell and right shell, be respectively arranged with the lock core hole inserting for inside and outside lock core, two of described lock bodies extend respectively has one to regulate by adjusting device the cantilever sliding up and down, on described cantilever, be fixed with clamp, the upper surface of described lock core is at least provided with a draw-in groove, and described clamp coordinates and snaps in draw-in groove downwards.

As a kind of optimal way, described adjusting device regulates and comprises the screw being rotatably provided on lock body, the conditioning box that has been threaded on the screw rod of described screw, described cantilever stretches out from conditioning box, and described screw rotarily drives conditioning box and slides up and down in lock body.

As a kind of optimal way, the upper surface of described lock core arranges two parallel clamp bar slots.

As a kind of optimal way, the lower limb of described clamp is set to the arc matching with lock core upper surface.

As a kind of optimal way, described clamp is set to middle part hollow out.

The utility model is in the time must changing lock core, regulate adjusting device upward sliding, cantilever drives clamp to move up, clamp is thrown off in draw-in groove, former lock core is taken out from lock core hole, new lock core is inserted to lock core hole, then regulate adjusting device down sliding, cantilever drives clamp to move down, and clamp snaps in draw-in groove; When the utility model is changed lock core, adjusting device need only be regulated, lock body need not be taken apart, simultaneously, the utility model also can only be changed internal cylinder or outer lock core, also can be by the exchange of interior outer lock core, as the lock core when only seeing room to intermediary using internal cylinder, namely in the time seeing room, interior outer lock core is exchanged, the key of internal cylinder, to intermediary, gains after renting a house again, thereby can in safety, reduce the expense of changing lock core.The utlity model has the feature that can change separately internal cylinder or outer lock core and can be convenient for changing lock core.

Detailed description of the invention

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The door lock of a kind of replaceable core of the present embodiment, please refer to Fig. 1 to Fig. 3, include lock body 4, cover left shell 2 and right shell 64 two of lock bodies, in described left shell 2 and right shell 6, be respectively arranged with the lock core hole 21,61 inserting for inside and outside lock core 1,7,4 two of described lock bodies extend respectively has one to regulate by adjusting device the cantilever 81 sliding up and down, on described cantilever 81, be fixed with clamp 3,5, the upper surface of described internal cylinder lock core and outer lock core 7 is at least provided with a draw-in groove 11,71, and described clamp 3,5 coordinates and snaps in draw-in groove 11,71 downwards.

This door lock is in the time must changing lock core, regulate adjusting device upward sliding, cantilever 81 drives clamp 3,5 to move up, clamp 3,5 is from draw-in groove 11,71 interior disengagements, former lock core is taken out from lock core hole, new lock core is inserted to lock core hole, then regulate adjusting device down sliding, cantilever 81 drives clamp 3,5 to move down, and clamp 3,5 snaps in draw-in groove 11,71; While changing lock core, adjusting device need only be regulated, lock body need not be taken apart, simultaneously, this door lock also can only be changed internal cylinder or outer lock core, also can be by the exchange of interior outer lock core, as the lock core when only seeing room to intermediary using internal cylinder, namely in the time seeing room, interior outer lock core is exchanged, the key of internal cylinder, to intermediary, gains after renting a house again, thereby can in safety, reduce the expense of changing lock core.This door lock has the advantages that can change separately internal cylinder or outer lock core and can be convenient for changing lock core.

The door lock of the replaceable core of the present embodiment, please refer to Fig. 1 to Fig. 3, on the basis of previous technique scheme, can also be specifically, adjusting device regulates and comprises the screw 10 being rotatably provided on lock body 4, a conditioning box 8 has been threaded on the screw rod of described screw 10, described cantilever 81 stretches out from conditioning box 8, and described screw 10 rotarily drives conditioning box 8 and slides up and down in lock body 4.

The door lock of the replaceable core of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can also be specifically, and the upper surface of lock core 7 arranges two parallel clamp bar slots 11.To facilitate in the installation without on thickness door.

The door lock of the replaceable core of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can also be specifically, and the lower limb of clamp 3 is set to the arc matching with lock core 1 upper surface.Thereby increase the fastness of clamping.

The door lock of the replaceable core of the present embodiment, please refer to Fig. 1, on the basis of previous technique scheme, can also be specifically, and clamp 3 is set to middle part hollow out.Thereby strengthen its longitudinal crushing resistance.

More than that the door lock of the utility model replaceable core is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be equivalent substitute mode, be included in protection domain of the present utility model in.
