Description

A kind of door lock built-in clutch device

Technical field

The utility model relates to lockmaking technical field, particularly a kind of door lock built-in clutch device.

Background technology

The electronic lock of prior art mainly comprises following components: door handle, lock body, electronic module, realize the controlling organization of handle and lock body interlock, and the core component of this controlling organization is exactly clutch.Electronics lock clutch mainly transfers drive one group of transmission mechanism by the positive and negative of motor, solenoidoperated cluthes from the state of closing, thus realize the Push And Release of door lock.

Electronics lock clutch is generally divided into two kinds, and what be loaded on lock body inside is referred to as built-in clutch, and the clutch be loaded in door handle structure is referred to as external clutch.

The reducing motor of existing built-in clutch is directly connected with rotating shaft or only uses a pair gear drive, therefore the dynamics of rotating shaft is not enough, clutch pushing block runs not steady, and because reduction gearing arranges unreasonable causing in prior art, the spacing between motor and pushing block is larger; Or driving wheel and output wheel or driven pulley are longitudinally arranged side by side, take up room large, be not easy the miniaturization realizing lock body size, thus when making that clutch is follow-up to be used on door lock, the spacing of handle and side plate is increased, cause lock body to take up room greatly.

Therefore prior art haves much room for improvement and develops.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of clutch and operates steadily, and reduces the spacing of pushing block to reducing motor, the door lock built-in clutch device taking up room little.

Technical solution of the present utility model is: a kind of door lock built-in clutch device, comprises the outer rotating shaft being arranged with spring, is provided for the driving mechanism that this rotating shaft rotates, with the pushing block of the first installing hole and the second installing hole; This rotating shaft is in turn through the first installing hole and the second installing hole, and the two ends of this spring are connected to the first installing hole and the second installing hole edge respectively; The part that its shaft is arranged with spring is also provided with spring retainer pin; And the external surface at rotating shaft two ends is respectively equipped with around this roller end first position limiting convex ring of a week and the second position limiting convex ring;

This driving mechanism comprises reducing motor, drive and output wheel, and this reducing motor output shaft is provided with driving wheel, and driving wheel engages with drive, and output wheel is arranged on the end of rotating shaft near the first position limiting convex ring; Drive engages with output wheel, and driving wheel and drive are longitudinally arranged.

Reducing motor drives driving wheel, and rotating speed passes on drive, and drive drives output wheel again, the spring retainer pin of rotating shaft is rotated in spring, orders about pushing block and move between the first position limiting convex ring and the second position limiting convex ring; Utilize gear to carry out excessive deceleration, increase dynamics, pushing block is moved more stable; Driving wheel and drive are longitudinally arranged, reduce the spacing of pushing block to reducing motor, thus after clutch is used in door lock, can reduce the spacing of handling position to side plate.

The speed reducing ratio of described driving wheel and described output wheel is 1:6.25.While the guarantee strength of gear teeth, improve the multiple of deceleration as much as possible.

Also comprise clutch base and clutch upper cover, clutch base is provided with the cavity holding described reducing motor, and corresponding described reducing motor upper and lower surface is provided with shock absorber part.Reducing motor can be made operationally to wait steadily.

The beneficial effects of the utility model:

Carry out excessive deceleration by reduction gearing, increase dynamics, clutch pushing block is moved more stable.The longitudinal direction arrangement of gear, can make reducing motor and rotating shaft longitudinally arrange, reduce the spacing of pushing block to reducing motor, reduce the spacing of handling position to side plate.

Detailed description of the invention

Embodiment:

Consult Fig. 1 Fig. 2 Fig. 3, a kind of door lock built-in clutch device, comprise the outer rotating shaft 1 being arranged with spring 2, be provided for the driving mechanism 3 that this rotating shaft 1 rotates, with the pushing block 4 of the first installing hole 41 and the second installing hole 42; This rotating shaft 1 is in turn through the first installing hole 41 and the second installing hole 42, and the two ends of this spring 2 are connected to the first installing hole 41 and the second installing hole 42 edge respectively; I.e. rotating shaft 1 and the first installing hole 41, second installing hole 42, spring 2 has same center line, and the part that its shaft 1 is arranged with spring 2 is also provided with spring retainer pin 11; The height of spring retainer pin 11 is greater than the distance of spring 2 to rotating shaft 1 external surface, and the rotating band of rotating shaft 1 is moved the rotation of spring spacer pin 11, thus spring 2 is compressed, and promotes the movement of pushing block 4.

And the external surface at rotating shaft 1 two ends is respectively equipped with first position limiting convex ring 12 and second position limiting convex ring 13 of a week around this rotating shaft 1 end; The diameter of position limiting convex ring is greater than the diameter of the first installing hole 41 and the second installing hole 42, makes pushing block 4 move between two position limiting convex rings and can not come off.

This driving mechanism 3 comprises reducing motor 31, drive 32 and output wheel 33, and this reducing motor 31 output shaft is provided with driving wheel 34, and driving wheel 34 engages with drive 32, and output wheel 33 is arranged on the end of rotating shaft 1 near the first position limiting convex ring 12; Drive 32 engages with output wheel 33, and driving wheel 34 is longitudinally arranged with drive 32, and drive 32 is coaxially connected with the second travelling gear 322 by the first travelling gear 321.First travelling gear 321 engages with driving wheel 34, and the second travelling gear 322 engages with output wheel 33, makes driving wheel 34 be 1:6.25 with the speed reducing ratio of output wheel 33.While the strength of gear teeth can be ensured, also improve the multiple of deceleration as much as possible.Drive 32 is longitudinally arranged with driving wheel 34 in addition, reduces the spacing of pushing block 4 to reducing motor 31.

Preferably be provided with gear bulge loop in the side of drive 32, output wheel 33 and driving wheel 34, prevent the landing between transmission process gear.

Also comprise clutch base 100 and clutch upper cover 200, clutch base 100 is provided with the cavity 101 holding reducing motor 31, and corresponding reducing motor 31 upper and lower surface is provided with shock absorber part 102, and this shock absorber part 102 is preferably foam-rubber cushion.Reducing motor can be made operationally to wait steadily.
