It is worth mentioning that, in addition to using the light-emitting device 193 to generate a light source to indicate that the door lock 10 is in the locked state and the light-emitting device 193 not to generate a light source to indicate that the door lock 10 is in the unlocked state, the inner operating device 92 can also use the light-emitting device 193 to generate different light sources. The color light source indicates the locked or unlocked state of the door lock 10. For example, when the door lock 10 is set to the locked state, the light-emitting device 193 generates a red light source to display on the transparent cover 195, and the door lock 10 is set to the unlocked state. When the light-emitting device 193 generates a green light source, it is displayed on the light-transmitting cover 195 . Alternatively, the light emitting device 193 can also be designed so that when the door lock 10 is set to the locked state, the light emitting device 193 does not produce bright light, and when the door lock 10 is set to the unlocked state, the light emitting device 193 produces bright light.

Alternatively, the door lock 10 can be equipped with different forms of the outer operating device 76. For example, the outer operating device 76 can also only consist of an outer locking cylinder 86 installed on the outer side 26 of the door 20 and a fixed handle. After the metal key unlocks the outer lock core 88 of the outer lock cylinder 86, the latch head of the latch device (for example, the latch device using the latch device disclosed in US Patent No. 8,641,104) is allowed to be operated using the outer lock cylinder 86 from the latched position. Move to the unlocked position.

The above description is only illustrative rather than restrictive for the present invention. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined by the application. All will fall within the protection scope of the present invention.
