Abstract

The utility model relates to an automatic lock of an electric coiling gate. The technical scheme includes that 1, two relays which control positive rotation and negative rotation of a motor of the electric coiling gate are connected in parallel and are double-pole double-throw relays, after being connecting in parallel, the two relays becomes single-pole and single-throw relays and cannot affect an original control circuit, and the lock is connected with a power source after being serially connected with the parallelly-connected relays through a lead, can be electrified when the motor is electrified to rotate positively or negatively and can be in power failure when the motor is in power failure; and 2, an unlocking device adopts a drawing electromagnet, when the drawing electromagnet is electrified, an iron core of the drawing electromagnet retracts, and when the drawing electromagnet is in power failure, the iron core of the drawing electromagnet extends. During opening or closing process of the gate, namely when the motor is electrified, the drawing electromagnet is also electrified, the iron core retreats to drive the bolt so as to realize unlocking, during complete opening or closing of the gate, namely when the motor is in power failure, the drawing electromagnet is also in power failure, and then the iron core extends out to realize locking. The lock is synchronous to the motor of the electric coiling gate, is electrified regardless of positive rotation or negative rotation of the electrified motor, and is in power failure when the motor is in power failure. The lock is automatically unlocked when the gate is opened and automatically locked when the gate is closed. The automatic lock has a function of increasing the safety of the electric coiling gate.

Description

Electric rolling gate door automatic locking

Affiliated technical field

The utility model relates to the electric rolling gate door lock.

Background technology

The present more general utmost point of electric rolling gate door, convenient and practical, but owing to can not adorn lock its safety is reduced greatly, the electric rolling gate door that a little bigger people of a general strength can check on is mentioned 50 centimetres high, if the thief that justs think enters the thing of stealing that just can stay calm and collected.But this situation few people know.Will be very inconvenient if it loads onto common rolling gate door lock, and if forget under the situation about opening the lock with the key by electric rolling gate Men Kaimen key motor will overload operation cause burning out, loss will be very big.

Summary of the invention

In order to overcome low this deficiency of safety, the utility model proposes a kind of automatic locking, it can be when press electric rolling gate Men Kaimen key auto-unlocking, in door pass following time, automatically lock.

The technical scheme that its technical problem that solves the utility model adopts is: dead bolt links to each other with the iron core of tractive magnet, electromagnet is connected with the transformer that it is equal to voltage, two relays of (rotating and reverse) are connected about transformer and the rolling door Electric Machine Control, electromagnet energising traction dead bolt is unblanked when motor rotates, and electromagnet outage reduction was just locked when motor stopped operating.Reach the purpose of high security.

The beneficial effects of the utility model are, do not influence its convenient and practical property when improving the safety of electric rolling gate door, and are simple in structure.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 1 is the utility model section of structure

Fig. 2 is the utility model "on" position section of structure

1. dead bolts, 2. triangle transmissions, 3. tractive magnets, 4 tractive magnets 5. unshakable in one's determination and tractive magnet are with voltage transformer 6. leads among the figure.

The specific embodiment

Dead bolt among Fig. 1 (1) is connected with tractive magnet iron core (3) by triangle transmission (2), tractive magnet (4) is connected with its same voltage transformer (5), lead (6) is connected the relay of (rotating and reverse) about the control of the utility model and electric rolling gate door motor, the electric rolling gate door close be motor when not switching on the utility model do not switch on and be locking state, promptly dead bolt (1) is for stretching out state.The effect of wherein triangle transmission (2) is: change the tractive magnet lead, reach the effect that reduces this lock cumulative volume.

Among Fig. 2, when unlatching electric rolling gate door is the electrical power rotation, the utility model energising, tractive magnet (4) work, traction dead bolt (1) is unblanked, and promptly dead bolt (1) is the indentation state.

Claims

1. electric rolling gate door automatic locking, in metal shell, dead bolt is connected with electromagnet core, electromagnet is connected with the transformer that it is equal to voltage, it is characterized in that: lock is installed on electric rolling gate every frame, connect with the relay of electric rolling gate door motor by lead, press electric rolling gate Men Kaimen key auto-unlocking, door automatically locks when closing.

2. automatic locking according to claim 1 is characterized in that: electromagnet is a tractive magnet; Two relays that (rotate and reverse) about the rolling door Electric Machine Control are parallel with one another, and lock is connected with relay in parallel.
