One side is provided with a slanted tongue paddle 5, and the starting plate 3 is provided with a starting plate rivet 4 near the three-bolt dial 12, and the upper gear plate 11 is provided with an upper gear plate rivet 10, and the lower gear plate 6 is provided with a lower gear Disk rivets 7, peg plate guide rivets are connected between the upper gear disk 11 and the lower gear disk 6

18. The three-bolt shifting plate 12 is connected with a peg plate return spring 20 near the starting plate 3 .

25. Embodiment, the three-bolt plate 14, the rivet 15 driven by the sky-earth rod and the bolt head 21 form a three-bolt assembly, which can move synchronously.

26. In the embodiment, the two groups of lock cylinder dial fixing pieces 8 are provided with arc notches, and the lock cylinder toggle gear plate 9 is socketed and connected with the arc grooves, and the two sets of lock cylinder dial fixing pieces 8 and the lock box 16 and the lock cover above the lock box 16 are all riveted by rivets, and the lock core to toggle the gear plate 9 and the upper gear plate 11 are meshed and connected, and the lock core is used to stir the inner lock core of the lock body to turn the gear plate. Drive the transmission of the lock body, avoiding the phenomenon that the original one-speed or two-speed mechanical lock body is equipped with full-automatic, causing the lock cylinder to be jammed and jumping out, and solve the problem that the lock body cannot be retracted or opened normally.

27. Embodiment, the side of the three-bolt dial 12 close to the upper gear plate 11 and the side of the three-bolt plate 14 close to the rivet 13 of the three-bolt toggle gear plate are provided with notches, so that the three-bolt dial 12 can follow the upper gear The promotion of the disc rivet 10 moves, so that the three-bolt plate 14 can move with the promotion of the three-bolt toggle gear disc rivet 13 .

28. Working principle: The transmission process during use is: key to close the door: the key rotates counterclockwise, and after a 30° idle travel, it drives the lock cylinder of the lock body to turn the gear plate 9 to rotate counterclockwise together, and the lock cylinder turns the gear plate 9 It can only be rotated along the arc notch of the lock core dial fixed piece 8, and the lock cylinder dial fixed piece 8 is respectively fixed on the lock cover of the lock box. When the lock cylinder moves the gear plate 9, the upper gear plate meshed with it 11 rotates clockwise around the peg plate guide rivet 18 in the middle, and at the same time the upper gear plate rivet 10 riveted on the upper gear plate 11 will rotate accordingly, and by cooperating with the left side of the notch of the three-bolt dial 12, the rotational force Transfer to the three-bolt dial 12, so that the three-bolt dial 12 also rotates clockwise around the guide rivet 18 of the bolt board, and at the same time, the three-bolt shifting gear disc rivet 13 riveted on the three-bolt dial 12 follows the three-bolt dial 12 rotate clockwise together, the three-bolt toggle gear plate rivet 13 will have an upward and rightward displacement during the rotation, and through the notch on the three-bolt plate 14, the three-bolt plate 14 will be pushed out of the lock, The three-bolt assembly can only move in two directions up and down, that is, the three-bolt assembly is shot out, and at the same time as the three-bolt assembly is shot out, the rivet 15 is driven by the upper and lower ends of the three-bolt plate 14 to drive the upper and lower two sky-earth rods 19 respectively. Stretch out, when the key is rotated to 90°, the three-bolt assembly is fully opened, and the two heaven and earth rods 19 are fully extended synchronously. The dead point of the movement of the plate 14 ensures that the three-bolt plate 14 will not be retracted due to external force, thereby realizing a reliable function of closing and locking the door.

29. Key to open the door: the key rotates clockwise for 30° idle travel, and then touches the lock cylinder to turn the gear plate 9, so that the lock cylinder turns the gear plate 9 to rotate clockwise together, and the lock cylinder turns the gear plate 9 to simultaneously make the upper gear plate 11 And the lower gear disc 6 rotates counterclockwise, and the upper gear disc 11 rotates to make the upper gear disc rivet 10 push the three-bolt dial 12, and the three-bolt toggle gear disc rivet 13 will leave the dead point of motion, and at the same time drive the three-bolt plate during the rotation process 14 is retracted to the inside of the lock body, and the three-bolt plate 14 pushes the rivet 15 through the sky-earth rod so that the two sky-earth rods 19 are retracted synchronously, and the lower gear plate 6 rotates clockwise, driving the lower gear plate rivet 7 riveted with it to rotate synchronously, and the lower gear The disc rivet 7 moves the tail of the latch bolt 5, so that the latch bolt 5 rotates clockwise around the dial shaft 2, and at the same time, the head of the latch bolt 5 moves the latch bolt 1, so that the latch bolt 1 is retracted into the lock body, After the key rotates clockwise to 90°, the retraction actions of the three bolt assemblies, the oblique tongue 1, and the heaven and earth rod 19 are completed synchronously, and the door can be pushed open this moment, and the door opening action is completed.

30. Handle to close the door: Turn the handle counterclockwise, that is, the dial shaft 2 rotates counterclockwise, and at the same time make the activation plate 3 sleeved on the dial shaft 2 rotate counterclockwise, the activation plate rivet 4 is riveted on the activation plate 3, and the activation plate rivet 4 is turned Move the three-bolt dial 12 to rotate clockwise around the guide rivet 18 of the three-bolt dial, and at the same time, the three-bolt shifting gear plate rivet 13 riveted on the front end of the three-bolt dial 12 rotates clockwise along with the three-bolt dial 12, and the three-bolt The rivet 13 of the toggle gear plate will have an upward and rightward displacement during the rotation process, and through the cooperation of the notches on the three-bolt plate 14, the three-bolt assembly will be pushed out of the lock, that is, the three-bolt assembly will be driven out, and the three-bolt assembly will be pushed out. While playing, push the rivets 15 through the heaven and earth rods riveted on the upper and lower ends of the three-bolt plate 14 to drive the upper and lower heaven and earth rods 19 to stretch out, and when the handle is rotated to 45°

Afterwards, it will not be able to continue to rotate, indicating that the three bolt assemblies and the heaven and earth rod 19 have been fully driven out at this time, and the door closing action is completed.

31. Open the door with the handle: Turn the handle clockwise to make the dial shaft 2 rotate clockwise synchronously. The clockwise rotation of the dial shaft 2 will drive the activation board 3 on it to rotate clockwise together, and the activation board riveted on the activation board 3 at the same time The rivet 4 pushes the three-bolt dial 12, so that the three-bolt dial 12 rotates counterclockwise around the bolt plate to guide the rivet 18, and at the same time, the three-bolt toggle gear plate rivet 13 pushes the three-bolt plate to the inside of the lock body through the notch of the three-bolt plate 14 To retract, push the rivets 15 riveted on the upper and lower ends of the three-bolt plate 14 to push the rivet 15 to simultaneously push the two-day rod 19 to retract. When the dial shaft 2 rotates clockwise, it will drive the oblique tongue pick 5 to rotate clockwise together, and the oblique tongue pick 5 Turn the latch bolt 1 clockwise to retract the latch bolt 1 to the inside of the lock body. When the handle cannot continue to rotate, turn it about 45°, indicating that the latch bolt 1 and the three bolt components have been retracted to the end, and you can push them away at this time door to complete the action of opening the door.

32. Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes can be made to these embodiments without departing from the principle and spirit of the present invention , modification, replacement and variation, the scope of the present utility model is defined by the appended claims and their equivalents.
