Abstract

The invention discloses an intelligent cathode lock. A micromotor is arranged in a lock body, and is provided with a worm which can drive a stirring fork to rotate to and fro; the stirring fork can rotate around a stirring fork pin shaft; the other end of the stirring fork runs through a hole on a lock block bracket; a lock block is fixed on the lock block bracket, and rotates together with the lock block bracket around a lock block pin shaft; a lug boss on the lock block can lock a lock rod; the other end of the lock rod can rotate on a lock rod pin shaft; a spring is arranged on the lock rod, and is supported on the lock body, so that the lock rod clings to an inclined surface on the rear part of a latch spring; and the latch spring is supported on the lock body by a shaft, can rotate on the shaft and is provided with a resetting spring which resets the latch spring.

Description

Intelligent cathode lock

[technical field]

The present invention relates to a kind of intelligent cathode lock on the door, in particular for being installed in the intelligent cathode lock on the various doorframes.

[background technology]

Cathode lock and common door lock are used, and cathode lock can be controlled the unlatching of dead bolt, under the situation of no door lock key, can open door by cathode lock, provide convenience for realizing that the control door is opened.Existing cathode lock belongs to Electromagnetic Drive, need the above dc source of 12V, if be used for single domestic consumer, not only cost is than higher, and need 220V to power, certain potential safety hazard is arranged, be difficult in the domestic consumer and apply, cathode lock is mainly used in various office spaces and the gate control system at present.

[summary of the invention]

The objective of the invention is to overcome the deficiency of existing cathode lock, a kind of novel intelligent cathode lock is proposed, the structure of this lock adopts micro machine to drive, only need the common batteries power supply, not only simple in structure, and safe and reliable, solved existing cathode lock power supply cost height well, the problem that is not easy in domestic consumer, apply.

Technical solution of the present invention is: a kind of intelligent cathode lock, comprise panel, lock body, its special character is: be provided with micro machine in the lock body, be fixed with worm screw on it, worm screw can promote shift fork and come back rotation, shift fork can rotate around the shift fork bearing pin, the other end of shift fork passes the hole on the lock dog support, lock dog is fixed on the lock dog support, and and the lock dog support rotate around the lock dog bearing pin together, the boss on the lock dog can lock locking bar, the other end of locking bar can rotate on the locking bar bearing pin, there is spring to be supported on the lock body on the locking bar, locking bar is abutted against on the snap close rear ramped surface, and there is corresponding inclined-plane locking bar and snap close rear ramped surface contact position, and snap close is supported on the lock body by axle, and can on axle, rotate, there is reduction torsion spring that snap close is resetted on the snap close.When intelligent cathode is locked in lock-out state, snap close lock door upper lock tongue can not open the door, when the Intelligent Recognition control system identification of intelligent cathode lock is unblanked, worm screw on the micro-motor is rotated and promotes the shift fork swing, the shift fork other end is stirred lock dog to lower swing, make the boss on the lock dog throw off locking bar, pulling this moment door hand, the door upper lock tongue drives the snap close upset opens door.The back Intelligent Recognition control system of unblanking makes the micro machine counter-rotating, and worm screw promotes the shift fork backward rotation, and the shift fork other end is stirred upwards swing of lock dog, and the boss on the lock dog locks locking bar again, and snap close is in the lock state again.

The shift fork of described intelligent cathode lock is made up of steel wire and shift fork seat, and steel wire is supported in the arm on the worm screw, is longer than the arm that passes the lock dog bracket holes, makes the thrust of worm screw have amplification.

The Intelligent Recognition control system of described intelligent cathode lock can be various recognition systems such as fingerprint recognition system, contactless card recognition system, remote control recognition system, TM card identifying system, IC-card recognition system.

The invention has the beneficial effects as follows, simple and compact for structure, safe and reliable, realized power supply of independent battery power supply and Intelligent Recognition control, cost is low, promptly can be used for also can being applicable in domestic consumer in various office spaces and the gate control system.

The present invention is further described below in conjunction with drawings and Examples

[specific embodiment]

At Fig. 1, among Fig. 2, be fixed with worm screw (8) on the interior micro machine of lock body (2) (7), worm screw (8) can promote shift fork (9) and come back rotation, shift fork (9) can rotate around shift fork bearing pin (10), the other end of shift fork (9) passes the hole on the lock dog support (6), lock dog (4) is fixed on the lock dog support (6), and and lock dog support (6) rotate around lock dog bearing pin (5) together, boss on the lock dog (4) can lock locking bar (11), the other end of locking bar (11) can be gone up at locking bar bearing pin (13) and rotate, there is spring (12) to be supported on the lock body (2) on the locking bar (11), locking bar (11) is abutted against on snap close (3) rear ramped surface, and locking bar (11) has corresponding inclined-plane with snap close (3) rear ramped surface contact position, and snap close (3) is supported on the lock body (2) by axle, and can on axle, rotate, there is reduction torsion spring that snap close (3) is resetted on the snap close (3).When intelligent cathode is locked in lock-out state, snap close (3) lock door upper lock tongue can not open the door, when the Intelligent Recognition control system identification of intelligent cathode lock is unblanked, worm screw (8) on micro machine (7) axle is rotated and promotes shift fork (9) swing, shift fork (9) other end is stirred lock dog (4) to lower swing, make the boss on the lock dog (4) throw off locking bar (11), pulling this moment door hand, the door upper lock tongue drives snap close (3) upset opens door.The back Intelligent Recognition control system of unblanking makes micro machine (7) counter-rotating, worm screw (8) promotes shift fork (9) backward rotation, shift fork (9) other end is stirred upwards swing of lock dog (4), and the boss on the lock dog (4) locks locking bar (11) again, and snap close (3) is in the lock state again.
