Implementation

As shown in Figure 1, a mechanical key transmission device based on an American standard lock body, including a lock head, a lock body shell 1, a mechanical key transmission rod 2, and a transmission adapter assembly 3; a mechanical key transmission rod 2, and a transmission adapter assembly 3 is assembled inside the lock body shell 1; the characteristic is that the lock body shell 1 has a lock head hole 11, a first positioning column 12, and a handle center hole 15; the transmission adapter assembly 3 is set in the handle center hole 15, and the transmission rotation The connection assembly 3 can rotate around the center hole 15 of the handle; the distance between the lock head hole 11 and the center hole 15 of the handle is 88.1mm±2mm; one end of the mechanical key transmission rod 2 is sleeved on the first positioning post 12, and The mechanical key transmission rod 2 can rotate around the central axis of the first positioning column 12;

There is a first transmission rod 31 on the transmission adapter assembly 3, and an end point 21 is provided on the mechanical key transmission rod 2, and the end point 21 is connected to the first transmission rod 31;

There is an input end 22 on the mechanical key transmission rod 2, and the input end 22 is connected to the lock head and driven by the lock head;

There is a second positioning column 13 and a third positioning column 14 on the lock body shell 1, a groove 23 is arranged on the mechanical key transmission rod 2, and the second positioning column 13 and the third positioning column 14 are installed in the groove. In 23, when the mechanical key transmission rod 2 moves up and down, the second positioning column 13 and the third positioning column 14 simultaneously ensure the direction of the vertical displacement of the mechanical key transmission rod 2;

The transmission adapter assembly 3 includes an upper input shifting block 32, an oblique tongue shifting block 33, a square tongue shifting block 34, a first transmission rod 31, a lower input shifting block 36, a second transmission rod 37, a return seat 38, and a return spring 39: The upper input shifting block 32, oblique tongue shifting block 33, square tongue shifting block 34, first transmission rod 31, and lower input shifting block 36 are concentrically assembled on the lock body shell and the five parts can rotate around the same central axis The return spring 39 is assembled on the reset seat 38 and the two can rotate around the same central axis; one end of the second transmission rod 37 is connected to the reset seat 38 and the other end is connected to the oblique tongue shift block 33 and the first transmission rod 31; the upper input shift block 32, the lower input shift block 36, the first drive rod 31 three are not directly connected to each other, and are respectively connected with the square tongue shift block 34, the oblique tongue shift block 33,
