Description

new safety lock

The utility model relates to the technical field of locks, and is a novel safety lock.

Areas that are often accessed, such as rooms or safes, need to be controlled, such as adding safety locks so that people who know their passwords can open and enter these areas. This safety lock includes a mechanical device with several coded buttons. Only when these buttons are activated according to a predetermined password can the locking mechanism of the lock be opened. Some safety locks are controlled by a keyboard or by inserting a pre-programmed memory, such as a magnetic card or IC. card to control. All these safety locks, in case of any failure, will bring bigger troubles to the user; on the one hand, it is impossible to enter the locked room or open the locked door cabinet, etc., on the other hand, because the structure of the safety lock is more reasonable, it is not easy to It is easy to break, and it takes a lot of effort to break its lock.

The purpose of this utility model is to provide a new type of safety lock that can enter the area controlled by the safety lock even if the safety lock breaks down in view of the above situation. The key control opens its safety lock.

The novel safety lock of the utility model includes a locking mechanism that is usually in a locked state, an actuating device that is used to make the locking mechanism open when activated and a safety device that controls the activation of the actuating device, and also includes a Alternative means for activating said activation means in accordance with the state of the safety means and indication means for indicating whether the alternative means has been used.

The replacement device is a key engaged with the keyhole on the safety lock. When the key is used, the starting device can be activated to open the safety lock.

The indicator device can know when the safety lock has been opened by the substitute device, thereby ensuring that the safety lock has a more secure effect; once the indicator device is used by the substitute device, it will provide a visual or audible alarm signal alarm system.

The replacement device is a key engaged with the lockhole, and the indicating device is a cover at the lockhole.

The above-mentioned cover is a thin film located at the keyhole which is easy to be pierced by a key; or the above-mentioned cover is an escutcheon which can rotate around a pivot.

Due to the adoption of the above-mentioned structure, the safety lock can ensure that the lock can also be opened through an alternative device when any failure occurs in the safety lock. It is convenient and reliable to use, and has an indicating device at the keyhole. The keyhole, on the other hand, can indicate when the lock has been opened by alternative means to make the safety lock more secure.

The following describes its structure and technical content in detail in conjunction with the accompanying drawings.

Fig. 1 is the first embodiment figure that the utility model is used for door lock (round handle);

Fig. 2 is another embodiment figure of the utility model.

The safety lock of the present utility model generally includes a locking mechanism that is usually in a locked state, an actuating device that is used to make the locking mechanism open when activated, and a safety device that controls the activation of the actuating device. Have done detailed description and explanation in (Taiwan.950726.1); Said starting device is decided according to the structure of safety device, as general safety device includes such as processor device and user interface, and the user starts this The interface can start the starting device, and the safety device can be a keyboard operated in a mechanical manner, or can be formed with a reader for reading a magnetic card, an IC card or other password carrying equipment; For detailed description, please refer to relevant literature, which is not reflected in the figure.

Referring to Fig. 1 and Fig. 2, the safety lock further includes an alternative device for activating the starting device regardless of the state of the safety device and an indication device for pointing out when the alternative device has been adopted; the alternative device includes The key 1 engaged with the keyhole, the key is engaged with the lock core in the lock and the starting device is activated to open the safety lock. For the structure of the lock core and the matching structure of the lock core and the starting device, please refer to the structure of some existing locks, which are not shown in the figure reflected, and will not be described in detail here. The key 1 in Fig. 1 is engageable in the keyhole 3 on the knob 10, and is generally used to make the knob 10 turnable regardless of the state of the safety device, so that in the event of a malfunction, it can be passed through the lock. The key opens the safety lock.

For security locks set in areas controlled by a locking mechanism, it is important to know if the security lock has been superseded or overridden.

Referring to Fig. 1, the indicating device is the cover 2 of the keyhole, and the cover in Fig. 1 is a film that is easily pierced by a key at the keyhole, and the keyhole is covered behind the cover 2, and the cover 2 is fixed on the circle of the door. In the recessed part 4 on the shaped handle 10. Cover 2 is made of fragile material.

Referring to Fig. 2, the above-mentioned cover 2 is an escutcheon that can rotate around the pivot 5. Normally, the cover 2 covers the keyhole. When the key needs to enter the keyhole 3, the cover rotates around the axis 5 so as to expose the keyhole 3 , In the figure, the cover is fixed on the round handle 10 of the door rotatably around the pivot 5.

In each of the above-mentioned situations, an indication that the cover has been moved can be provided mechanically or electronically, and a suitable light-sensitive device can also be provided at the end of the keyhole; or a permanent or temporary protection against the return of the cover can be provided. The device which covers the position of the keyhole.

Among the various schemes mentioned in the application, only the general principle has been introduced, and other structural methods can also be adopted to achieve the purpose of the present utility model.

The above-mentioned key may include a master key and a sub-key. Please refer to relevant documents for the relevant structure, and no detailed description is given here.
