Abstract

The utility model relates to an electromagnetic clutch, in particular to a transmission part in various intelligent locks, which is applied in the occasion that a drive plate and a driven plate clutch at a relatively fixed place. The electromagnetic clutch comprises a support, a drive plate, a driven plate, a slide shoot, a locking iron, an electromagnet, a keeper and a spring. The electromagnet is fixed on the support, the locking iron can move along the slide groove on the support, the slide shoot can move along the slide groove on the driven plate and is resisted by the locking iron in the front. When not being electrified, the keeper opens, while the plate is working, the slide shoot is pressed by the inclined plane on the drive plate and the locking iron is driven to swing inwards by the slide shoot, the drive plate is not capable of driving the driven plate. While being electrified, the keeper closes to prevent the locking iron from sliding, the locking iron prevents the slide shoot from moving, so that the slide shoot and the driven plate can be driven by the drive plate. The device has the advantages of less power loss, reliable movement and longer service life.

Description

Magnetic clutch

(1) technical field

The utility model relates to a kind of magnetic clutch, is applicable to that driving disc and driven disc carry out the occasion of clutch on relatively-stationary position, mainly is the handle drive part in the various intelligent locks.

(2) background technique

In intelligent lock, because often use battery, so that power consumption seems is very important as power supply.Therefore a lot of door locks are not to use the motor driven dead bolt, but by the mechanism controls door lock handle, in the former door lock product, at blocking, handle is by locked, can not rotate, but be to use rough power may destroy the locking mechanism of handle, then still can rotatory handling, drive dead bolt, realization is opened the door, and from then on door lock damages, and can not use again.Therefore now generally add clutch in the back of door lock handle, when door lock is in blocking, clutch be in from state, handle can rotate, but be idle running, can not drive dead bolt, when door lock is in unlocked conditions, clutch, rotatory handling can drive dead bolt, realizes opening the door.

(3) summary of the invention

In order to reduce the power consumption of clutch, improve life-span and reliability, the utility model provides a kind of new clutch mechanism.

The technological scheme that its technical problem that solves the utility model adopts is:

Use sliding bamboo shoot to carry out clutch between the driving disc of clutch and the driven disc, electromagnet is fixed on the support, and gib can move by the chute on support, and sliding bamboo shoot can be moved by the chute on driven disc, and the front-end face of gib props up sliding bamboo shoot.When electromagnet is not switched on, armature opens, when driving disc rotates, the sliding bamboo shoot of inclined-plane compressing on the driving disc, sliding bamboo shoot drive gib and inwardly swing, therefore driving disc can not drive driven disc, when electromagnet was switched on, the armature closure stoped gib to slide, gib stops sliding bamboo shoot to be moved, so driving disc can drive sliding bamboo shoot and driven disc rotates.

The utility model has the advantages that:

1. owing to used electromagnet, action just becomes very simple and reliable.

2. low in energy consumption, though the efficiency of movement of electromagnet is not high,, make that driving force is very little by appropriate design, driving torque is but very big.

3. good reliability, reliability is for the door lock particular importance.

(5) embodiment

Illustrated is a kind of magnetic clutch, and it comprises support (1), driving disc (2), sliding bamboo shoot (3), gib (4), armature (5), spring (6), electromagnet (7), driven disc (8), reed parts such as (9).

Driving disc (2) and driven disc (8) are arranged in the hole of support (1), hole on the support (1) is imperfect, one section breach is arranged, gib (4) can move in the chute of support (1), the back of gib (4) has spring (6) to support, the front-end face of gib (4) is circular-arc, be positioned at the indentation, there in the hole of support (1), driving disc has vee on (2), the inclined-plane of breach contacts with the inclined-plane of sliding bamboo shoot (3), sliding bamboo shoot (3) can be moved in the chute of driven disc (8), the ear end face of sliding bamboo shoot (3) and the circular-arc front-end face of gib (4) contact, and electromagnet (7) is fixed on the support (1), and armature (5) is arranged on the electromagnet (7), when electromagnet (7) is switched on, armature (5) closure, the front-end face of armature (5) is aimed at gib (4) ear end face, when electromagnet (7) no electric circuit, armature (5) opens, and armature (5) front-end face and gib (4) ear end face stagger.

In Fig. 6 and Fig. 8, when electromagnet (7) no electric circuit, armature (5) opens, and gib (4) can move, and driving disc (2) rotation drives gib (4) by the inclined-plane sliding bamboo shoot of compressing (3) and retreats, and driven disc (8) does not rotate.

In Fig. 5 and Fig. 7, when electromagnet (7) was switched on, armature (5) closure stoped gib (4) to retreat, and driving disc (2) drives sliding bamboo shoot (3) and driven disc (8) rotation.

Claims

1. one kind is used for the magnetic clutch that driving disc and driven disc need carry out clutch in the fixed position, be applicable to the drive part of various intelligent locks, it comprises support, driving disc, driven disc, sliding bamboo shoot, gib, electromagnet, parts such as armature, it is characterized in that: driving disc and driven disc are arranged in the hole of support, and the hole on the support is imperfect, and one section breach is arranged, gib can move in the chute of support, the back of gib has spring to support, and the front-end face of gib is circular-arc, is positioned at the indentation, there of bracket holes, have vee on the driving disc, the inclined-plane of breach contacts with the inclined-plane of sliding bamboo shoot, and sliding bamboo shoot can be moved in the chute of driven disc, and the ear end face of sliding bamboo shoot and the circular-arc front-end face of gib contact, electromagnet is fixed on the support, armature is arranged above the electromagnet, when electromagnet is switched on, the armature closure, the front-end face of armature is aimed at the gib ear end face, when the electromagnet no electric circuit, armature opens, and armature front-end face and gib ear end face stagger.
