Detailed Description
Examples: an indoor emergent unlocking mechanism of push-and-pull lock, a door opening induction device 1 is fixedly installed in the push-and-pull lock, a contact 3 is arranged on a square bar poking rack 2 of the push-and-pull lock, the contact 3 on the square bar poking rack 2 of the push-and-pull lock can be just inducted by the door opening induction device 1 when the square bar poking rack 2 is automatically reset from a handle door opening state to a door closing state, the door opening induction device 1 is signaled in a push-and-pull lock control system, and a motor 4 can be controlled by the push-and-pull lock control system to implement electric unlocking actions.
The push-pull lock works normally according to the following working principle: locking process: after the door is closed, the sensing tongue 5 on the lock body is pressed into the lock body by the door frame against the elastic force. Meanwhile, the induction tongue triggers an induction tongue control switch 6 in the lock body, a push-pull lock control system (a singlechip) receives a door closing signal, the push-pull lock control system controls a motor 4 to work, a side wall stop function of an end face groove of a square tongue poking gear 7 drives a square tongue poking button 8 to rotate, and a poking square tongue 9 stretches out of the lock body to realize square tongue locking. After the locking is finished, the motor 4 rotates reversely, the square tongue poking gear rotates reversely simultaneously, and the sensing element on the reset gear 10 meshed with the square tongue gear rotates to the reset sensing optocoupler sensor 11. After the optical coupler sensor is triggered to give a reset signal to the push-pull lock control system (single chip microcomputer), the push-pull lock control system (single chip microcomputer) controls the motor 4 to stop rotating. At this time, the bulge on the square tongue pulling button just has a movable space in the groove on the end face of the square tongue pulling gear, and the unlocking and locking can be implemented by pure mechanical control.
When the reset induction optical coupler sensor is damaged, the reset gear rotates without positioning measures. The square tongue poking gear drives the square tongue poking gear Niu Shisuo and then cannot reset normally, the protrusion on the square tongue poking button is still blocked by one side wall of the groove on the end face of the square tongue poking gear, the protrusion on the square tongue poking button is blocked in the square tongue poking gear and has no moving space, at this time, the push-pull handle 12 performs indoor unlocking action, the handle drives the square bar poking rack 2 to slide for a certain distance through the transmission mechanism, the contact 3 on the pull rack 2 is separated from the door opening induction device 1, and in the abnormal case, the square bar induction contact 3 on the square tongue is kept at the position of the square tongue closing induction optocoupler sensor 14, and the square tongue opening induction optocoupler sensor 15 does not detect the square bar induction contact 3. At the moment, the handle returns under the action of the spring, the contact 3 on the pulling rack 2 and the door opening sensing device 1 are opposite to generate sensing signals, at the moment, the push-pull lock control system (single chip microcomputer) gives an instruction to the motor 4 to enable the motor to move so as to realize electric unlocking, and at the moment, the door can be opened by pushing and pulling the handle. That is, the push-pull lock can be used for unlocking the door lock indoors no matter whether the reset sensing optical coupler sensor is damaged or not. The situation that the handle cannot drive the square tongue pulling button to unlock due to the damage of the reset induction optical coupler sensor is avoided. And further, serious consequences caused by incapability of opening the indoor door in emergency are avoided.
The contact 3 on the square bar toggle rack 2 of the push-pull lock is of a protruding structure, the door opening sensing device 1 is a light touch switch, the protruding structure on the square bar toggle rack 2 can just touch the contact piece of the light touch switch when the push-pull lock handle is reset, the light touch switch can also be replaced by an optocoupler sensor, a Hall sensor and the like, namely, the door can be reset under the elastic action and not opened as long as the handle is sensed after push-pull.
The square bar of push-pull lock is stirred protruding structure on the rack 2 and is stirred the trapezoidal arch of rack 2 slip direction both sides for the hypotenuse along the square bar, is equipped with the gyro wheel on the contact of tact switch, and gyro wheel circumference outside surface can contradict with trapezoidal arch, through inclined plane and gyro wheel contact, avoids protruding structure and tact switch's shell fragment to take place the card system and damage the shell fragment.
The shell of the push-pull lock comprises a front cover and a rear plate, wherein the front cover is fixedly covered on the surface of the rear plate, an accommodating space is formed between the front cover and the rear plate, and the door opening sensing device 1 is fixedly arranged on the rear plate of the shell of the push-pull lock.
An unlocking control method of an indoor emergency unlocking mechanism of a push-pull lock comprises the following specific steps:
step one: closing the door, wherein an induction tongue on the door is pressed into the lock body by the door frame against the elastic force;
step two: the sensing tongue triggers a sensing tongue control switch in the lock body, and the control system receives a door closing signal;
step three: the control system electrifies the motor 4, and the motor 4 drives the square tongue to lock;
step four: under the normal condition of the reset induction optocoupler sensor, the motor 4 rotates reversely, the motor 4 drives the square tongue poking gear to rotate reversely at the same time, and then the induction element on the reset gear meshed with the square tongue gear is driven to rotate to the reset induction optocoupler sensor, the induction element triggers the optocoupler sensor to give a control system reset signal, the motor 4 stops rotating, and the bulge on the square tongue poking button just has a movable space in the groove of the end face of the square tongue poking gear; under the condition that the reset induction optical coupler sensor is damaged, the motor 4 does not rotate reversely, and the bulge on the square tongue pulling button does not have a movable space in the groove on the end face of the square tongue pulling gear;
step five: pulling the handle, resetting the normal condition of the inductive optical coupler sensor, and driving the square tongue to retract by the handle through the transmission mechanism to realize door opening; under the condition that the reset induction optocoupler sensor is damaged, the handle drives the square bar to stir the rack 2 to slide for a certain distance through the transmission mechanism, the contact 3 on the pull rack 2 is separated from the door opening induction device 1 for induction, the square tongue cannot retract, the square tongue opening induction optocoupler sensor does not detect the square bar induction contact 3, the handle is loosened, the handle returns under the action of the spring, the contact 3 on the pull rack 2 is opposite to the door opening induction device 1 to generate an induction signal, the control system supplies power to the motor 4, and the electric inversion enables the protrusion on the square tongue pull button to have a movable space in the groove on the end face of the square tongue pulling gear;
