Description

Remote control latch with door lock

The invention belongs to the technical field of door locks for buildings, and particularly relates to a lock device capable of wirelessly opening and closing a door (window) by using a remote controller.

Background technique

In the prior art, a common anti-theft door lock with a key-opening is easy to be hacked by a thief; one is a magnetic card lock, which is generally used in hotels and guest houses, but its anti-smashing performance is poor; The lock of the lock pin has a strong anti-smashing function, but the mechanical resistance of the lock device is large, so it is still necessary to use a mechanical method to open the key. However, the lock of the mechanical lock is also easily opened illegally by the thief, so it is still very unsafe. Moreover, the phenomenon of the door lock being technically stolen has become more and more fierce, and it has reached the point where it is impossible to prevent it. New technical means are urgently needed to solve this problem.

Summary of the invention

The technical problem to be solved by the present invention is: In view of the above-mentioned phenomena and technical defects, a remote control latch with a door lock for a remote control for a security door is provided, and the remote control latch of the security door is not only easy to be Destruction can also prevent thieves from using traditional means to unlock.

The technical solution of the present invention is that the remote control latch with a door lock, as shown in Figs. 1 to 2, has a casing 1 with a lid 11, and the casing 1 is provided with an anti-theft door lock 3 and a bolt 4. The technical feature is that a remote control pin 2 is arranged on the box body 1 in parallel with the anti-theft door lock 3, and the remote control pin 2 is provided with a pin body 23 in the same direction as the lock tongue of the anti-theft door lock 3, and the pin body 23 faces The inner end is connected with a rack 21, and the box body 1 on the side of the rack 21 is radially provided with a micromotor 24, and the output end of the micromotor 24 is coupled to a gear 22 matching the rack 21 of the pin body 23 and passes through The gear 22 and the rack gear 21 drive the pin body 23, and further, the casing 1 is further provided with a power source 26 and a signal receiver 25 equipped with a remote controller 27, and the signal receiver 25 is electrically connected to the micro motor 24 described above. .

When the present invention thus constructed is used, referring to Figs. 1 to 3, the signal receiver 25 is controlled by the remote controller 27, and the remote controller 27 sends a signal to the signal receiver 25 to activate or deactivate the micromotor through the signal receiver 25. 24, the gear 22 of the micro-motor 24 teeth drive the rack 21, thereby driving the pin body 23 that is connected with the rack 21, so that the pin body 23 linearly reciprocates to realize the extension of the pin body 23. Shrink, and then open and close the door (window).

The invention adds a remote control latching device on the basis of the original door lock. The traditional latch is that the plugging operation can be performed indoors, and the invention adopts the latest scientific and technological numerical control means, and can realize the automatic latching of the indoor latch by using the remote controller outside the door. If a thief uses a master key to open the door lock, and there is no remote control to release the switch, it still cannot enter the room. When the owner of the house and the whole family travel, they don't have to worry about being stolen. The product of the invention is especially suitable for banks, other financial units, financial offices, gold and silver treasury, confidential rooms, archives, residential houses and the like.

As described above, the present invention is to add a remote control latch device on the basis of the original door lock, and to change the tradition that the plug pin device can only be operated indoors, and the remote control device can be used to open and close the indoor latch. . At this time, even if a thief uses the master key to open the door lock, the thief cannot enter the room without the lock of the remote controller releasing the pin.

The circuit control of the present invention uses a DC power source 26, i.e., a battery, and uses the remote controller 27 to emit a signal, so that the pinion 23 can be controlled by the signal receiver 25.

The invention has the beneficial effects that the invention can control the opening and closing of the door by using the remote controller to control the expansion and contraction of the pin body, that is, the door lock locking structure is reinforced and optimized, and the disadvantages that the conventional pin device can only be operated indoors are overcome. , so that the owners can go to work, travel, and travel, without fear of being stolen, especially banks, financial units, and financial offices with large amounts of gold and silver jewelry and confidential documents. Since the remote control can adopt the branding technology, the plug of the invention can increase the advantages of strong confidentiality, convenient operation, and suitable for both young and old.
