Abstract
The utility model discloses a clutch of an electric door lock, which comprises a gear wheel or a shift fork (1), a reset spring (2), a driving marble (3), a sliding marble (4), a left and a right pushing blocks (5) and an inner spring (7), wherein the gear wheel or the shift fork (1) and a transmitting wheel (8) in an electric drive are on the same axis, and the gear wheel or the shift fork (1) is provided with a lug boss (9) which is provided with a central hole and extends into the transmitting wheel (8); the lug boss (9) and the transmitting wheel (8) are provided with radial slots (11) in a radial direction, and the outer ends of the radial slots (11) are sealed; each of the radial slots (11) is orderly provided with the reset spring (2), the driving marble (3) and the sliding marble (4) inwards; the left and the right pushing blocks (5) are arranged along the axis of the central hole of the transmitting wheel (8), and the inner spring (7) is arranged between the two pushing blocks (5); when the gear wheel or the shift fork (1) contacts a driving end (6) in a mechanical key transmission mechanism, a transmission pair is formed.
Description
Technical field
The utility model relates to a kind of clutch of electromechanical transmission mechanism separation of electric door lock.
Background technology
Existing electronic remote control anti-theft lock is digital remote control logic lock, and this is locked without any mechanical opening device, can only press remote controller and just can unblank, even if owner does not have remote controller can't pass in and out yet, at all can't inlet chamber when remote controller is lost in.If electric door lock will have the mechanical key tapered end, the clutch that electromechanical transmission mechanism is separated just must be arranged.
Summary of the invention
The utility model provides a kind of clutch of electric door lock, and it can make the electric door lock that has the mechanical key tapered end realize that electromechanical transmission mechanism separates.
The utility model is achieved in that the clutch of electric door lock, be arranged between the electric transmissio mechanism and mechanical key transmission mechanism of door lock, it is mainly by gear or shift fork, back-moving spring, drive pellet shot from a slingshot, the slip pellet shot from a slingshot, left side pushing block, right pushing block and inner spring are formed, drive in described gear or shift fork and the electric transmissio mechanism is on same axis, and the boss that gear or shift fork are provided with the band centre bore stretches in the drive, described boss and drive radially are provided with the radial slot of outer end sealing, outside in be provided with back-moving spring in the radial slot successively, drive pellet shot from a slingshot and slip pellet shot from a slingshot, centre bore axis along drive is provided with left pushing block and right pushing block, be provided with inner spring between two pushing blocks, described gear or shift fork form transmission when drive end in the mechanical key transmission mechanism contacts.
At pushing block described in the utility model and gear or the adjacent end face of shift fork is taper type; It between slip pellet shot from a slingshot and the radial slot little matched in clearance; Described drive can be worm gear or gear; The outside of described left and right pushing block is respectively the left and right driving end in the mechanical key transmission mechanism, when the left and right driving end moves inward and gear or shift fork form transmission.
After adopting as above technical scheme, as opening and closing door lock with motor drive mechanism, drive end in the mechanical key transmission mechanism is failure to actuate, inner spring makes left and right pushing block be positioned at original position, driving pellet shot from a slingshot in the radial slot is between gear or shift fork, drive, with both lockings, when drive rotates, gear or shift fork rotate thereupon, realize the open and close of electric operating door lock.When opening and closing door lock with mechanical key, mechanical key promotes drive end and moves to the inside, driving pushing block moves to the centre, the frustum of pushing block end face withstands the slip pellet shot from a slingshot and moves radially, drive pellet shot from a slingshot and also move thereupon, drive pellet shot from a slingshot and be arranged in drive fully, realize that gear or shift fork separate with drive, but drive end driven gear or shift fork rotate like this, realize open and close manual or mechanical key operation door lock.Clutch is provided with left and right two pushing blocks in the utility model, can be from the manually opened door lock in both sides, innner and outer of door.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A sectional view of Fig. 1
The specific embodiment
With reference to accompanying drawing, the clutch of the utility model electric door lock is installed between the electric transmissio mechanism and mechanical key transmission mechanism of door lock.Clutch mainly is made up of gear or shift fork 1, back-moving spring 2, driving pellet shot from a slingshot 3, slip pellet shot from a slingshot 4, left pushing block 5, right pushing block 5 and inner spring 7.Drive 8 in gear or shift fork 1 and the electric transmissio mechanism all is provided with the boss 9,10 of band centre bore vertically, the boss 9 of gear or shift fork stretches in the boss 10 of drive, two boss radially are provided with the radial slot 11 of outer end sealing, outside in be provided with back-moving spring 2 in the radial slot 11 successively, drive pellet shot from a slingshot 3 and slip pellet shot from a slingshot 4, slip pellet shot from a slingshot 4 stretches out radial slot 11 at next end of effect of back-moving spring 2, driving pellet shot from a slingshot 3, slip pellet shot from a slingshot 4 and radial slot 11 is little matched in clearance, and assembling back slip pellet shot from a slingshot 4 can not drop out radial slot 11.Be provided with left pushing block 5 and right pushing block 5 along axis in the boss 10 of drive 8, be provided with inner spring 7 between the left and right pushing block 5, left and right pushing block 5 and slip pellet shot from a slingshot 4 adjacent end faces are taper type, are convenient to pushing block 5 when the centre is mobile, and it is outwards mobile radial slot 11 in to promote slip pellet shot from a slingshot 4.The outside of left and right pushing block 5 is the drive end 6 in the mechanical left and right driving key transmission mechanism, forms transmission when drive end 6 contacts with gear or shift fork 1.Drive 8 in the electric transmissio mechanism is worm gear in the drawings, and it can be a gear etc.
