Abstract

The utility model relates to a double-clutch anti-theft lock body used for an electronic door lock, which is provided with two sets of independent clutch devices. If one set of clutch device fails, the other set of clutch device can be used similarly, i.e. the lock is unlocked by an electronic means. Clutch pins in the clutch devices are electrified by a motor and then indirectly driven by rotation in the counterclockwise or clockwise direction. Therefore, the lock body has two states of unlocking and locking a door.

Description

Two clutch antitheft locks

Affiliated technical field

The utility model relates to the lock body that a kind of electronic lock uses.

Background technology

At present, all be the device that adopts single clutch at the employed antitheft lock in electronic lock field, and this pair clutch antitheft lock have the independent arrangement of clutch of two covers, when a cover arrangement of clutch is out of order, can use an other cover arrangement of clutch to unblank.

Summary of the invention

In order to overcome single clutch antitheft lock that existing electronic lock generally uses under the out of order situation of arrangement of clutch, the deficiency that can't use the means of electronics to unblank, antitheft lock of the present utility model has two and overlaps independently arrangement of clutch, if wherein a cover arrangement of clutch breaks down, an other cover arrangement of clutch can use electronically to unblank equally.

Description of drawings

Below in conjunction with accompanying drawing 1 and embodiment the utility model is further specified

Parts list in the accompanying drawing 1 is as follows:

The dash number part name

1 motor-1

2 worm screws-1

3 torsion springs-1

4 on-of pin pushing pieces-1

The explanation of two clutch antitheft lock

One, technical scheme

(1), the on-of pin-the 1st in the accompanying drawing 1, be in door opening state.

(2), the on-of pin-the 2nd in the accompanying drawing 1, be in the state of locking a door.

(3), so-called pair of clutch of the utility model be meant on-of pin-1 or on-of pin-2 any be in door opening state, rotate front handlebar and can open the door.

Two, the specific embodiment

(1), motor-1 rotates counterclockwise in first cycle conduction time, drive worm screw-1 and rotate counterclockwise.Worm screw-1 rotates counterclockwise, and drives torsion spring-1 around axle A counter-clockwise swing.Torsion spring-1 counter-clockwise swing drives on-of pin pushing piece-1 and swings clockwise around axle B.At this moment, on-of pin-1 is fully retracted under the thrust of clutch pushing piece-1, is in door opening state (as shown in Figure 1).

(2), motor-1 clockwise rotates second cycle conduction time, drive worm screw-1 and clockwise rotate.Worm screw 1-clockwise rotates, and drives torsion spring-1 and swings clockwise around axle A.Torsion spring-1 is swung clockwise, drives on-of pin pushing piece-1 around axle B counter-clockwise swing.At this moment, on-of pin-1 ejects under the thrust of clutch spring-1 fully, is in the state of locking a door.

(3), motor-2 rotates counterclockwise in first cycle conduction time, drive worm screw-2 and rotate counterclockwise.Worm screw-2 rotates counterclockwise, and drives torsion spring-2 around axle C counter-clockwise swing.Torsion spring-2 counter-clockwise swing drives on-of pin pushing piece-2 and swings clockwise around axle D.At this moment, on-of pin-2 is fully retracted under the thrust of clutch pushing piece-2, is in door opening state.

(4), motor-2 clockwise rotates second cycle conduction time, drive worm screw-2 and clockwise rotate.Worm screw-2 clockwise rotates, and drives torsion spring-2 and swings clockwise around axle C.Torsion spring-2 is swung clockwise, drives on-of pin pushing piece-2 around axle D counter-clockwise swing.At this moment, on-of pin-2 ejects under the thrust of clutch spring-2 fully, is in the state of locking a door (as shown in Figure 1).

(5), on-of pin-1 or on-of pin-2 any be in door opening state, rotate front handlebar, front handlebar moving block 8 can rotate counterclockwise around axle E simultaneously with handle rotating stand 9, and drives oblique tongue plectrum 19 and rotate counterclockwise around axle E, oblique tongue assembly 18 is drawn in lock body side plate 17 fully, realize opening the door.

The beneficial effects of the utility model are, in the time of can arbitrary cover arrangement of clutch is out of order in two cover arrangement of clutch, use another set of arrangement of clutch to unblank.

Claims

1. the lock body that uses of an electronic lock, arrangement of clutch is arranged in lock body, wherein the on-of pin in the arrangement of clutch be by behind the electrical power counterclockwise or clockwise rotate indirectly and drive, thereby lock body is opened the door and lock a door two states, it is characterized in that: antitheft lock of the present utility model has two and overlaps independently arrangement of clutch, if wherein a cover arrangement of clutch breaks down, an other cover arrangement of clutch can use equally, realizes unblanking.
