Description

Core

The utility model relates to a kind of lock, relates in particular to the core of lock.

At present traditional door lock is generally all unblanked by metal key, yet, when adopting this method to open door lock, must carry severally when people go out on one's body metal key, make carrier's pocket comparatively lofty and the carrier is felt under the weather.

Discuss with suitcase in addition, the locking device major part of suitcase all is with the control interlinked mechanism with a small-sized metal key, be used as unlocking tool with small-sized metal key, yet, open the small-sized key of suitcase for general traditional type, the volume of this small-sized key of cause is less, thereby very easily loses, and suitcase can't be opened.In addition, traditional door lock or Suitcase lock are all opened by rotating with metal key, and be of long duration, and key is crooked easily or twisted off and can not re-use.

Main purpose of the present utility model is to be to provide a kind of core, and this core just can reach the purpose of opening this core as long as use card key by pressing down this card key.

The technical solution of the utility model is to provide a kind of core, this core is made up of institutes such as pedestal, elevating bracket, the lock pin with short slot, core and lock dogs, several cylindric lock pins with short slot can lay respectively at different lock pin groove inside, between the bottom of lock pin and pedestal, have a lock pin spring respectively, it is characterized in that:

This pedestal is hollow form, and this elevating bracket is hollow form and can places the inner and upper of pedestal, and elevating bracket respectively extends to form a  type hollow projection towards both sides, and the inner bottom part of  type hollow projection is respectively vertically to be provided with a coil spring;

One core is arranged at the top of pedestal, and the central authorities of this core form a longitudinal socket, and the place ahead of core has a horizontal cylinder groove, and its inner ccontaining one horizontal cylinder forms several lock pin grooves at the internal layout of core;

One lock dog, its central authorities also form a slot corresponding to aforesaid slot, and can make core be contained in the inside of lock dog, and forming one in the inwall in the face of the lock dog of slot can be for the arc groove that holds horizontal cylinder, and the combination of mat said structure can be formed a complete core.During use, insert the slot of lock dog, core, press down this card key and just can open this core with a card key with several concave, convex teeth.

By above technical scheme as can be known, core of the present utility model is compared with traditional core and is had following advantage:

(1). core of the present utility model is opened with card key, as long as just can open core by pressing down the action that card key need not to reverse card key, so have long service life, can not twist off key, the advantage easily of unblanking.

(2). open the card key of the utility model core, because of area is bigger slightly than general small-sized key, so be difficult for losing.

(3). the card key of opening the utility model core can entirely be put in pocket, and must to carry several metal key comparatively lofty and carry uncomfortable phenomenon in pocket so solved traditional key.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.

This lock core structure mainly comprises: pedestal 20, elevating bracket 30, the lock pin 40 with short slot 41, core 50 and a lock dog 60 etc.;

This pedestal 20 is hollow form, and its section is the U font, and an Extendible flake 21 that has perforation 22 on it is respectively extended in the both sides of pedestal 20;

This elevating bracket 30 is hollow form and can places the inner and upper of pedestal 20, respectively extend to form a  type

hollow projection

31,32 on the elevating bracket 30, and the inner bottom part of  type

hollow projection

31,32 is respectively vertically to be provided with a

coil spring

33,34, in addition each extends to form a medial end that has lug 35, the one L type fixture blocks 37 of dog hole 36 on it and colludes respectively in the dog hole 36 towards its outside by  type

hollow projection

31,32;

One core 50 is arranged at the top of pedestal 20, the both sides of this core 50 extend to form a projection 51,52 respectively, the central authorities of core 50 form a longitudinal socket 53, the place ahead of core 50 has a horizontal cylinder groove 54, portion's ccontaining one horizontal cylinder 55 within it forms several lock pin grooves 56 at the internal layout of core 50;

Several lock pins 40 that are cylindric and have a short slot 41 can place respectively in the different lock pin grooves 56, have a lock pin spring 42 respectively between the bottom of lock pin 40 and pedestal 20, and lock pin spring 42 provides suitable elasticity for lock pin 40;

One lock dog 60, its central authorities also form a slot 61 corresponding to aforesaid slot 53, and can make core 50 be contained in the inside of lock dog 60, and make two projections 51,52 lay respectively at the inside of lock dog 60, inwall in the lock dog 60 of facing slot 61 forms an arc groove 62 in addition, and the effect of this arc groove 62 is to hold horizontal cylinder 55.
