Abstract
The utility model discloses a lock. The lock is mainly characterized in that a concave hole (01-1) is arranged on the facade of a key (01), and a lock bead (04) which is matched with the concave hole (01-1) and a clamping block (06) which is matched with the lock bead (04) are arranged inside a lock core (02). A lock bead clamping hole (06-1) is arranged on the clamping block (06), a radial groove (04-1) is arranged on the lock bead (04), and the radial groove (04-1) and the lock bead clamping hole (06-1) on the clamping block (06) are mutually matched. A clamping groove (07-1) is arranged on the inner wall of a lock shell (07), and the clamping groove (07-1) and the clamping block (06) are mutually matched. The lock bead (04) and the tail part of the clamping block (06) are all provided with elastic elements (03) and (05). The utility model is compared with the prior art, due to the fact that the lock is opened after the lock bead clamping hole on the clamping block passes through the radial groove on the lock bead, and therefore, the anti-theft effect of the lock is obviously enhanced.
Description
Technical field: the utility model relates to a kind of lock core structure of lockset, refers to that especially a kind of core that makes has the stopper effect when locking, and makes the burglar be difficult for unblanking and increases the lockset of anti-theft effect.
Background technology: the kind of lockset is numerous, and according to the operating characteristic that its purposes is had nothing in common with each other, wherein has a kind of lock core structure to be useful in steel cable lock and use.This lockset is sheathed core in sleeve, and core is by lock core, fixed body, end pin, lock pin and spring are formed, having lockhole on this lock core inserts for key, and lock core can be inserted in the fixed body, and all be provided with several corresponding perforations on lock core and the fixed body, in perforation, be inserted in the different end pin of length and lock pin and spring, and a cover plate covered perforation top side at fixed body, so that with the perforation sealing, simultaneously, but the other end interlock one stopper bar of rotor, and the stopper bar can stretch into sleeve, nationality is with the stopper tapered end, stretch into the keyhole of lock core when key after, can rotational lock core and drive the retraction of stopper bar and unblank.
But, when above-mentioned lockset is locked in the use,, and lock core can't be rotated and reach the function of locking because lock pin stretches out between the perforation of lock core and fixed body, therefore, when the burglar unblanked with unlocking tool, (promptly do not need ten minutes accurately the end to be sold and the junction of lock pin is evenly shifted onto near the intersection of lock core and fixed body, promptly available brute force was rotated lock core not need accurately to shift end pin and lock pin onto location, and lockset is opened, therefore, anti-theft effect still has to be strengthened
Summary of the invention: the purpose of this utility model is: the defective that overcomes prior art, a kind of lock core structure of lockset is provided, it has the dual clip locking function of lock pin group and drawing piece simultaneously after locking, and then the difficulty that the increase burglar unblanks is to increase the anti-theft effect of lockset.
The purpose of this utility model realizes by following technological means: this kind lockset, comprise key, lock core, lock housing, the described guide groove that is provided with on the key, described lock core is provided with the guide groove raised line, the front that it is characterized in that described key is provided with shrinkage pool, be provided with lock pearl of matching and the blocking block that matches with the lock pearl in the described lock core with shrinkage pool, described blocking block is provided with lock pearl hole clipping, described lock pearl is provided with radial groove, described radial groove matches with lock pearl hole clipping on the blocking block, the inwall of described lock housing is provided with the stopper groove, and described stopper groove matches with blocking block, and the afterbody of described lock pearl and blocking block is equipped with flexible member.Described flexible member is a back-moving spring.Radial groove on the described lock pearl is located at the middle part of lock pearl.The utility model compared with prior art behind the radial groove on the lock pearl hole clipping process lock pearl that must make on the blocking block, just can be unblanked, and therefore, anti-theft effect obviously strengthens.
Description of drawings: the utility model has following accompanying drawing;
Fig. 1 is a component assembly structure schematic diagram of the present utility model;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model blocking figure;
Fig. 4 is the utility model unlocking condition figure.
The specific embodiment: accompanying drawing has been described structure of the present utility model, further describes the relevant details of its structure below more in conjunction with the accompanying drawings.This kind lockset, comprise key, lock core, lock housing, the described guide groove 01-2 that is provided with on the key, described lock core 02 is provided with guide groove raised line 02-1, the front of described key 01 is provided with shrinkage pool 01-1, be provided with lock pearl 04 of matching and the blocking block 06 that matches with the lock pearl in the described lock core 02 with shrinkage pool 01-1, described blocking block 06 is provided with lock pearl hole clipping 06-1, described lock pearl 04 is provided with radial groove 04-1, described radial groove 04-1 matches with lock pearl hole clipping 06-1 on the blocking block 06, the inwall of described lock housing 07 is provided with stopper groove 07-1, and described stopper groove 07-1 matches with blocking block 06, and the afterbody of described lock pearl 04 and blocking block 06 is equipped with flexible member.Described flexible member is a back-moving spring 03,05.Radial groove 04-1 on the described lock pearl 04 is located at the middle part of lock pearl.
Place in the lock housing 07 as long as have the lock core of blocking block 06 and lock pearl 04 after the utility model will make up, and block by snap ring 08.In the time of under blocking, will unblanking, guide groove raised line 02-1 along lock core 02 inserts with key 01, the shrinkage pool 01-1 in key front is contacted with lock pearl 04 end face 04-2, drive lock core 02 rotation by key 01 then, the stopper groove 07-1 that blocking block 06 is broken away from the lock housing 07, in lock core 02 rotation process, the radial groove 04-1 on the lock pearl 04 in the lock core 02 can fall into the lock pearl hole clipping 06-1 place on the blocking block 06, both unblanked, otherwise can not unblank.
