Detailed Description

The key parts of the invention are composed of a coded lock (1), a guy cable (2), a pull handle (3), a coded lock box (4), an outer cover (5), an alarm equipment box (6), a press disconnecting switch (7), an alarm bell (8), a battery (9), an outer cover screw rod (10) and a clamping screw rod (11). The method comprises the following steps:

a door leaf near or at an unlimited distance outside a door lock body is provided with a hole, a cipher lock box (4) and an alarm equipment box (6) are respectively arranged from the outside of a door leaf chamber and the inside of the door leaf chamber and are fixed by a clamping screw rod (11), a cipher lock (1) is arranged in the cipher lock box (4), a rotary disc of the cipher lock (1) is provided with a guy cable (2), the other end of the guy cable (2) is provided with a pull handle (3) which reaches the square shaft of the lock body through the inner wall of the door leaf so that a square hole on the pull handle (3) is sleeved on the square shaft of the existing lock body or the pull handle (3) is fixed on the square shaft of the existing lock body by adopting; a battery (9), an alarm bell (8) and a press disconnection switch (7) are arranged in the alarm equipment box (6), and a screw rod (10) of the outer cover is arranged to press a button of the press disconnection switch (7) when the outer cover (5) is fastened.

The basic principle of the above scheme is explained by using fig. 1, fig. 2, fig. 3 and fig. 4, namely, the dial plate on the coded lock (1) is rotated to pull the cable (2), so that the pull handle (3) is pulled and then the square shaft on the lock body is pulled to realize unlocking. (existing lock bodies are all rotating square shafts which can be unlocked, and no description is needed)

The invention can be mounted against a lock case and can also be mounted in the position illustrated in fig. 6, 7 and 8 as a hidden look and look like a cat eye or a trademark or door stop. The installation method is illustrated by using fig. 5, namely, a lock box (4) of the invention is installed from the outside of a door leaf, a guy cable (2) with one end connected with a driving plate on a coded lock (1) and the other end connected with a pull handle reaches the square shaft of a lock body through the inner wall of the door leaf, and a square hole on the pull handle (3) is sleeved on the square shaft of the lock body. (as described in connection with figures 1, 2, 3, and 4), (or the pull cup may be otherwise secured to the square shaft of the existing lock body without further detail); the alarm equipment box (6) is arranged from the indoor surface of the door leaf, the two boxes are clamped by a clamping screw rod (11), and finally, an outer cover (5) is covered and fastened by an outer cover screw rod (10).

When the anti-theft lock needs unlocking, the outer cover screw rod (10) on the outer cover (5) is detached, the button of the press off switch (7) in the alarm equipment box (6) is loosened while the outer cover screw rod (10) is detached, so that the power supply supplied by the battery (9) to the alarm bell (8) is switched on to generate alarm, for outsiders, the time is saved to try to open the coded lock (1) after the alarm is generated, while the owner is not afraid of generating the alarm, the coded lock (1) is rotated after the accurate code is dialed, the turntable on the coded lock (1) is rotated to pull the inhaul cable (2), and the pull handle (3) is pulled to pull the existing square shaft of the lock body to realize unlocking; after the combination lock is unlocked, the combination lock (1) is rotated reversely, so that the inhaul cable (2) is fully loosened, other unlocking modes are not influenced, the combination on the combination lock (1) is disordered, and the outer cover (5) is covered for emergency use next time.

In conclusion, no matter a mechanical lock or an intelligent lock is locked, a master can quickly open the intelligent lock by himself, the era of relying on unlocking service can be ended, the intelligent lock can thoroughly throw away keys to ensure safety, the intelligent lock can be quickly opened by himself without needing professional personnel when emergency such as fire disaster needs to be quickly opened for rescue, the disaster situation is minimized, and the design purpose is achieved.
