Abstract
A clutch typed anti-jimmying lock comprises a lock core, a gear set of the lock core, a lock pole and a gear set of the lock pole, and is characterized in that the lock structure is provided with a clutch component which is provided with a prepositioned gear and a postpositioned gear. The prepositioned gear is occluded by the gear set of the lock core and the postpositioned gear is occluded by the gear set of the lock pole. A drive plate is arranged at side part of an outer sleeve of the lock core and the lock cylinder, the drive plate can drive a pusher dog through a spring rocking arm, and the pusher dog can turn the clutch cover. Through controlling the clutch component to separate the rotation of the prepositioned gear and the postpositioned gear, a jimmying of locks by thieves can be avoided. The clutch typed anti-jimmying lock has simple structure and convenient use. When a key which is not corresponding to the lock is inserted into a lock hole, the lock core idles which can not be damaged forcibly and has a strong anti-jimmying and anti-theft function.
Description
Technical field:
The utility model belongs to a kind of lockset, and a kind of disengaging type pick-proof lock particularly is provided.
Background technology:
Existing door latch structure generally is made up of tapered end, locking bar and dead bolt, rotates by the key that matches with tapered end, drives locking bar and stretches out, and reaches the purpose that locks.But existing door lock is simple in structure, and the offender often makes an issue of on tapered end, and tapered end is easy to be prized bad, and then burglary.
Summary of the invention:
The purpose of this utility model provides a kind of disengaging type pick-proof lock, and it adopts clutch to come control lock core gear group and interlock of locking bar gear train and disengaging, and then reaches the purpose of pick-proof.
The technical solution of the utility model is: a kind of disengaging type pick-proof lock, comprise lock core and gear train thereof, locking bar and gear train thereof, it is characterized in that also having in the described lock construction clutch pack, this arrangement of clutch is linked together as central axis by declutcher control lever successively by spacer, preposition gear, rearmounted gear, fixed head, separation stator, clutch holder and clutch lid, be provided with one between preposition gear and the rearmounted gear and make its pin key that rotates simultaneously, and between clutch lid and clutch holder, be provided with the separation steel ball of three symmetries; Above-mentioned preposition gear and the interlock of lock core gear group, rearmounted gear and the interlock of locking bar gear train; Sidepiece at lock core and lock core sleeve also is provided with a driving chip, between tapered end shell and lock core cover, be provided with a thimble that has spring, when this thimble rotates under external force, lock core then drives concave wheel piece and rotates together, concave wheel piece then can back down the pusher dog of driving chip action drives sheet by spring rocking arm driving top, and allocated catch can be rotated above-mentioned clutch lid.
Disengaging type pick-proof lock provided by the utility model, simple in structure, easy to use, therefore Lock cylinder idling when thief inserts the key that does not conform to from lockhole can not destroy lock core by force, has very strong pick-proof, anti-theft feature.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure schematic diagram of Fig. 1.
Fig. 3 is the structure sectional view of clutch pack.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.As shown in Figure 1 and Figure 2, this pick-proof lock structure comprises lock core and gear train 1, locking bar and gear train 2 thereof, also have a clutch pack 7 in the lock construction, this clutch pack 3 is linked together as central axis by declutcher control lever successively by declutcher control lever 31, preposition gear 32, rearmounted gear 33, separation stator 39, clutch holder 35 and clutch lid 34.Be provided with a pin key that it is rotated simultaneously between preposition gear 32 and the rearmounted gear 33.And between clutch lid 34 and clutch holder 35, being provided with the separation steel ball 38 of three symmetries, steel ball 38 is stuck in the steel bead groove of clutch lid and clutch holder under general state.
Above-mentioned preposition gear 32 and 1 group of interlock of lock core gear, rearmounted gear 33 and 2 interlocks of locking bar gear train.Sidepiece at lock core and lock core sleeve also is provided with a driving chip 4, the pusher dog 6 above driving chip 4 drives by the spring Rocker arm 5, and allocated catch can be rotated above-mentioned clutch lid, makes to separate steel ball releasing slots position.
After the key that is not inconsistent with lock core inserts lock core and rotates, lock core drives lock core sleeve and rotates, the cam bit that is connected with lock core sleeve orders about the driving chip displacement after rotating, and drives allocated catch and moves by rocking arm, clutch actuating arm, and then make the moving steel ball that separates of clutch cover tape leave original groove position.The snap ring 37 that clutch covers lifts declutcher control lever 31 under the effect of spring 36, is positioned at the middle pin key of preposition gear and rearmounted gear and also is raised, and causes the front and rear gear to separate and rotates.How so no matter rotational lock core, the locking bar gear can not rotate, and then locking bar can not be opened.And if after first wife's the key insertion rotation, lock core sleeve is motionless, driving chip, rocking arm, pusher dog and clutch drive not action of arm, and front and back gear in the clutch or synchronous the rotation are opened locking bar by the locking bar gear train, form the process of unblanking normally.
In order to make this lockset that the remote closing function be arranged, side at rocking arm is provided with a longitudinal tie, the lower end of pull bar is provided with a projection, its upper end is connected with remote-control motor, by remote controller pull bar is moved up and down, and then make the projection of lower end back down rocking arm, form separating equally to preposition gear and rearmounted gear.By remote controller direct solenoidoperated cluthes just, any key all can not be unblanked like this.
