Technical Field

The invention relates to an electronic lock for a side-by-side combination door, and belongs to the technical field of locks.

Background

The existing oppositely-opening door lock mainly uses a motorcycle lock or a chain lock, and the technical problems of the oppositely-opening door lock are as follows: 1. the lever handles at the two sides of the split door are locked in a binding mode, and the two locked doors still swing to a larger extent along the opening and closing direction of the door under the action of external force, so that the gap between the two doors is enlarged, and the anti-theft performance is poor. 2. The lock body is separated from the binding part, so that the use is inconvenient.

Disclosure of Invention

The invention aims to solve the technical problems of poor anti-theft performance and inconvenient use in the prior art, and provides a side-by-side electronic lock with high anti-theft performance and convenient use.

To achieve the above object, an electronic lock for a side by side combination door of the present invention comprises:

the end part of the lock shell is hinged with a lock catch plate which can swing around a hinged shaft, the middle part of the lock shell is provided with a telescopic adjusting plate and a fixing screw, and the end part of the fixing screw props against two side wings of the adjusting plate;

a motor is arranged in the lock shell and drives a worm, the worm is meshed with a worm wheel and drives a pinion, the pinion is meshed with a sector gear and drives a transmission gear, the transmission gear is meshed with a rack, and the rack is arranged on the latch bolt pull rod and is matched with the latch bolt pull rod for use;

a lock head is arranged in the lock shell and is in contact fit with the end part of the latch bolt pull rod;

an electronic control circuit is arranged in the lock shell and is connected with the motor.

The lock shell root is equipped with the parallel recess that can hold the articulated shaft, and the tip is equipped with the lockhole that can hold the little tip of hasp board.

The root of the lock catch plate is provided with a notch capable of accommodating the articulated shaft, and the small end part is provided with a blind hole capable of accommodating the latch bolt.

Round holes are transversely formed in the two end portions of the hinge shaft, and screws penetrate through the round holes to fix the hinge shaft in the notch of the lock catch plate.

The articulated shaft is sleeved with a torsion spring, and two ends of the torsion spring respectively support against the lock shell and the lock catch plate, so that the force for swinging the lock catch plate around the articulated shaft can be generated.

The lock shell and the lock catch plate are both provided with windows for acquiring electric signals.

The two side wings of the adjusting plate are inserted into the lock shell and fixed by fixing screws arranged on the lock shell, and the top end surface of the adjusting plate is matched with a rod lever handle of the split door for use.

The lock head is transversely arranged in the lock shell, and the key hole is formed in the side face of the lock shell.

The end part of the latch bolt pull rod is fixed with a latch bolt and is provided with a pressure spring, the middle part is provided with a rack, and the other end part is in contact fit with the lock head for use.

Compared with the prior art, the technical scheme of the invention has the following advantages:

according to the electronic lock for the split door, when the door is locked, the lock shell is inserted between the split door and the two rod piece handles, and forms a lock closed loop for the two rod piece handles together with the lock catch plate and the adjusting plate. After the two rod handles are locked, two doors of the split door cannot have overlarge door seams, and the anti-theft performance is enhanced. When opening the door, give the signal of an unlocking signal or open the tapered end with mechanical key through cell-phone APP or electronic control panel or remote control key on the lock shell, the tip of hasp board perks rapidly, and the restraint of lock shell, regulating plate and hasp board to the member lever handle will be relieved convenient to use.

The split doors are closed, the lock shell is inserted between the two doors and the lever handle of the rod piece, the end part of the lock catch plate is pressed, the lock catch plate overcomes the elasticity of the torsion spring and swings around the swinging shaft, the small end part is inserted into the lock hole of the lock shell and touches the latch bolt, and the latch bolt and the pull rod of the latch bolt compress the pressure spring to generate retraction. After the small end of the locking plate passes over the oblique tongue, the oblique tongue is popped out again under the action of the pressure spring and enters the blind hole at the small end of the locking plate, and the locking is realized.

When the electronic control circuit is used for unlocking, according to an unlocking electric signal given by a mobile phone APP or a remote control key or an electric signal acquisition window, a motor connected with the electronic control circuit drives a worm, the worm drives a worm wheel, a pinion fixed together with the worm wheel drives a sector gear, a transmission gear fixed together with the sector gear drives a rack, the rack drives a latch bolt pull rod and a latch bolt through a rivet, and the latch bolt retracts and withdraws from a blind hole at the small end part of a lock catch plate. At this time, under the elastic force of the torsion spring, the lock catch plate tilts, and the lock shell and the lock catch plate release the constraint of the lever handle, namely, the lock is unlocked.

When the mechanical key is used for unlocking, the key is inserted into a key hole of the lock head, the key is rotated, the lock head drives the latch bolt pull rod, the latch bolt pull rod drives the latch bolt, the latch bolt retracts, and the lock is unlocked like the electronic unlocking.

The adjusting plate has the following functions: because the size and the installation position of the split door are different in the market, the distance between the handles of the two rod pieces is different, the handles of the two rod pieces are locked, and the adjusting plate is arranged for limiting. The two side wings of the adjusting plate are inserted into the lock shell, and the end face of the plate props against the lever handle. If the distance between the handles of the two rod pieces is short, the adjusting plate moves outwards the lock shell so as to reduce the locking length of the lock body. If the distance between the handles of the two rod pieces is longer, the adjusting plate moves towards the inside of the lock shell so as to increase the locking length of the lock body. After the position is adjusted, two fixing screws arranged at the bottom of the lock shell are screwed down.

The oscillating shaft is mounted and fixed in such a way that: firstly, the torsion spring is sleeved on the swing shaft, the swing shaft parallelly penetrates through the parallel groove at the heel part of the lock shell and is placed in the notch at the root part of the lock catch plate, then, the screw penetrates through the round holes at the two ends of the swing shaft to fix the swing shaft on the lock catch plate, and the lock catch plate is hinged with the lock shell.
