Description

Hand-operated gear

Technical field

The utility model relates to a kind of hand-operated gear, belongs to door lock technical field.

Background technology

At present, door lock is people's requisite parts of living, and general door lock requires to have certain theftproof performance, is convenient for people to open or close simultaneously.Therefore, the transmission device in door lock, just seems very important.And conventional door lock transmission type is many, more common is that lock core is positioned at lock body inside, and single or multiple teeth and lock body transmission by lock core carry out opening door lock.Mechanical key enable possition is positioned at lock housing external surface, and such shortcoming has two: (1) lock core has taken the very large space of lock body, and space availability ratio is low.(2) theftproof is poor, and mechanical key enable possition hides difficulty.

Utility model content

The purpose of this utility model is to provide that a kind of space availability ratio is high, theftproof is good hand-operated gear.

To achieve these goals, the technical solution of the utility model is as follows.

A kind of hand-operated gear, comprise handle, embed lock core and driving shaft in handle, on described lock core, adopt jump ring to be fixed with dead bolt, dead bolt activity is engaged in one end of driving shaft, described handle, lock core and driving shaft are coaxial setting, and one end of the movable engagement of described driving shaft and dead bolt is provided with smooth hill start.When lock core is opened, dead bolt rotates along hill start, due to hill start effect, promotes driving shaft displacement forward.

Further, described hand-operated gear is also included to arrangement of clutch, when driving shaft along with the rotation of dead bolt forward displacement until with the joint pin engagement of arrangement of clutch, make lock core, driving shaft, joint pin intermeshing, pulling handle now, door lock is opened.

Further, described lock core internal construction adopts the blade construction that is greater than 10 blades, and its advantage is that safety factor is high, and safe class is more than B level.

Further, described handle comprises handle, and described handle comprises handle casing, handle slip lid, front chute board and rear slide plate; Described front chute board has the first through hole and the second through hole, and described the first through hole is corresponding with the keyhole of lock core, and screw can be fixed on front chute board in handle casing through described the second through hole; Described front chute board edges at two ends place is also respectively arranged with the first slideway; Described rear slide plate has third through-hole and fourth hole, and described third through-hole is arranged on the U-shaped groove of rear slide plate, and screw can be fixed on rear slide plate in handle casing through described fourth hole; Described rear slide plate edges at two ends place is also respectively arranged with the second slideway; Described handle slip lid is slidably connected by chute and the first slideway, second slideway at its two ends.

Further, described slip lid inner side is provided with stopper slot, and described stopper slot is arranged on slip lid centre position.

Further, described handle slip lid inner side has blind hole, and described blind hole is arranged on stopper slot one side position.

Further, described handle slip lid inner side has anyhow staggered rib; Its advantage is intensity and the rigidity that increases slip lid, avoids the distortion of plastic.

Further, have the first protruding hole in described handle casing, screw is inserted in the stopper slot of described slip lid by the first protruding hole, thereby makes slip lid can slide within the specific limits but can not come off from handle.

Further, also have the second protruding hole in described handle casing, screw can be fixed on slip lid on handle by the second protruding hole, and its advantage is that keyhole is hidden, and avoids the artificial deliberate destruction to lock core.

Further, the material of described front chute board is ABS material.

Further, the material that described rear slide plate adopts is ABS material.

In this device, lock core is embedded in handle, has greatly saved overall structure space.In addition, the concealed assembling mode of lock core has also played good anti-theft feature.The segment design of chute board, greatly reduces processing technology, has saved cost of manufacture.Under normal condition, handle slip lid is slidably connected on handle handle, and door lock drives arrangement of clutch by energising, thereby make joint pin and driving shaft engagement on arrangement of clutch, swing handle now, lock core, driving shaft, the joint pin of coaxial engagement rotate under the drive of handle, thus door lock is opened, when abnormal conditions appear in door lock, in the time of cannot carrying out intelligence and open the door, slip lid in slide handle, expose and be hidden in the keyhole in handle originally, thereby by key operated door lock, now the dead bolt of lock core rotates with key interlock and along the hill start of driving shaft, due to hill start effect, dead bolt promotes driving shaft and moves forward, driving shaft promotes the joint pin in arrangement of clutch, impel itself and driven square shaft to mesh, now pulling handle door lock is opened. and the setting of slip lid upper limit position groove, make slip lid can only slide within the specific limits and cannot come off from handle, greatly reduced the possibility that slip lid is lost, guaranteed the integrality hand-operated gear.

The beneficial effect of this utility model is: this contrive equipment can significantly be saved the space of installation, has good anti-theft feature, and this application of installation, in door lock electronic lock particularly, can be improved to functional performance and the scope of application of door lock greatly.
