Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples.

As shown in fig. 1 and fig. 2, the door lock of the present embodiment includes a handle assembly 300, a code sheet circuit board 200, and a state control circuit board 100.

Referring to fig. 1 and 2, the handle assembly 300 includes a handle 301, a handle connecting pin 302, a torsion spring 303, a rotating shaft 304, and a rotating shaft limiting pin 305. Two rotating shaft limiting pins 305 are arranged on the side wall of the rotating shaft 304, and the two rotating shaft limiting pins 305 form a 90-degree included angle. During assembly, the rotating shaft 304 is assembled in a rotating shaft hole, and a 180-degree open slot is formed in the wall of the rotating shaft hole. The main body of the rotating shaft 304 is rotatably disposed in the rotating shaft hole, and the two rotating shaft limiting pins 305 are limited in the open slots of the rotating shaft hole, so that the rotating angle of the rotating shaft 304 is 90 degrees (i.e., the unlocking position and the locking position of the door lock). The front end of the rotating shaft 304 is provided with a handle assembly groove 309, the handle 301 is T-shaped, the tail end of the handle 301 is hinged in the handle assembly groove 309 at the front end of the rotating shaft 304 through a handle connecting pin 302, the handle 301 is 90 degrees relative to the rotating shaft 304 when folded back, and is 180 degrees relative to the rotating shaft 304 when unfolded. The handle connecting pin 302 is sleeved with a torsion spring 303, one end of the torsion spring 303 props against the inner side of the handle 301, the other end of the torsion spring 303 props against the handle assembling groove 309 of the rotating shaft 304, the handle 301 can automatically bounce up from 90 degrees relative to the rotating shaft under the action of the torsion spring 303, and the handle 301 is unfolded to be 180 degrees relative to the rotating shaft 304 (namely, coaxial with the rotating shaft 304).

As shown in fig. 1, a rotation shaft mounting hole 101 is formed in the state control circuit board 100, and two state switches 102 are respectively disposed on two sides of the rotation shaft mounting hole 101. Referring to fig. 2, the rotating shaft 304 penetrates through the rotating shaft assembling hole 101, the two rotating shaft limiting pins 305 are located at the rear side of the state control circuit board 100, and when the rotating shaft 304 rotates to the unlocking position and the locking position, the two rotating shaft limiting pins 305 respectively touch the state transfer switches 102 at two sides of the rotating shaft assembling hole 101. Thereby, the state control circuit board 100 detects the on-off state of the rotary shaft 304 and transmits the state transition information to the chip circuit board 200.

Referring to fig. 1, the chip circuit board 200 is electrically connected to the state control circuit board 100, and the chip circuit board 200 generates ID codes in different states under the trigger of the state conversion information provided by the state control circuit board 100, so as to be read by the code reading module of the computer key.
