The torsion spring positioning column 25 in the body 1 is connected; the side wall of the clutch movement 14 is radially and horizontally provided with a clutch pin 32, and the clutch pin 32 is driven by a driving mechanism. The inboard circle of the clutch shaft 15 is provided with a draw-in groove 33 cooperating with the clutch pin 32, the clutch pin 32 is covered with a spring 34, and the spring 34 is arranged in the clutch pin hole on the side wall of the clutch core 14, so The end of the clutch pin 32 extends to the outside of the outer circumference of the clutch core 14; the drive mechanism includes a motor 35, a driving wheel 36, a driven wheel 37 and a clutch pushing shaft 38, and the driven wheel 37 is connected to the clutch pushing shaft 38, The clutch push shaft 38 drives the clutch block 39 to move horizontally through the transmission mechanism, and drives the clutch pin 32 to do left and right telescopic movements through the clutch block 39; hole, and set apart from the clutch pin hole, a one-way pin 40 is arranged in the pin hole, and a blocking cover 41 is provided at the outer opening of the pin hole, and a return spring 42 is arranged between the one-way pin 40 and the blocking cover 41 , the lower end of the one-way pin 40 extends into the through hole 16 of the clutch core 14, and one side is provided with a slope 43, the outer circle of the inner clutch shaft 12 and the inner circle of the outer clutch shaft 15 are provided with There is a brake groove 44 that cooperates with the one-way pin 40; the side wall of the clutch core 14 is longitudinally provided with a reversing pin 30 parallel to the center line of the through hole 16, and the first toggle block 19 is provided with Groove 31 cooperating with reversing pin 30. The specific application process is as follows:

1. Compared with Example 5 of this embodiment, the external latch tongue toggle piece is subtracted. When the door closes, the latch pops up, and the inner handle can be pressed down to open the door, but the outer handle cannot be opened due to the lack of connection between the outer latch toggle and the outer clutch shaft. .

2. Locking action: the locking of the inner handle is the same as that of embodiment 5, and the locking of the outer handle is the same as that of embodiment 5.

3. Unlocking action The unlocking of the inner handle is the same as in embodiment 5, and the unlocking of the outer handle is the same as in embodiment 5.

In order to optimize the technical effect of the above-mentioned solution and to better limit the position, the middle part of the one-way pin 40 has a step 45, and the pin hole is a stepped hole matched with the one-way pin, and the one-way pin 40 has a large The bottom is small, its upper end is square, one side of the lower end is a slope, and the other side is a straight edge. The brake groove 44 on the outer platform circle of the inner clutch rotating shaft 12 and the inner platform circle of the outer clutch rotating shaft 15 is a rectangular groove. The bottom of the engaging groove 33 on the outer circle of the inner clutch shaft 12 and the inner circle of the outer clutch shaft 15 is an arc that matches the clutch pin 30 . Do useless work when the side of the braking groove applies force to the inclined plane of the one-way pin, and the inner clutch rotating shaft and the outer clutch rotating shaft can be driven to rotate when applying force to its straight side.

As a further optimization scheme, the motor 35 and the driving wheel 36 of the drive mechanism are two sets, wherein the motor and the driving wheel can be used one by one, and the two motors 35 are all arranged on the motor support 46, and the two motors 35 The driving wheels 36 are all meshed with the driven wheels 37, the clutch block 39 is arranged on the push shaft support 47, and the clutch push shaft 38 is connected with the clutch block 39 through a transmission mechanism.

In order to further optimize the technical effect of the above scheme, a main tongue limit switch 48 is also provided in the lock body 1, and the locked and unlocked states of the main bolt can be detected by using the main tongue limit switch; An oblique bolt accommodating groove 49 is provided, and when the main bolt is stretched out in the locked state, the oblique bolt can be pressed to the position of the oblique bolt accommodating groove because the main tongue push piece moves to the left to keep out of the position of the oblique bolt accommodating groove. The inside of the oblique bolt receiving groove is rotated 180 degrees for reversing to meet the needs of left or right door opening, and then the oblique bolt automatically protrudes under the thrust of the oblique bolt spring. When the door is opened, the oblique bolt is pushed by the main tongue. The gear cannot be completely pressed into the oblique bolt receiving groove of the lock body, and the direction cannot be changed. This design can prevent children from accidentally pressing the oblique lock tongue and getting stuck in the lock body.

In summary, the present invention has the advantages of compact structure and convenient operation. The present invention can further improve the anti-theft performance and requirements on the premise of dual-circuit dual-drive clutch anti-theft lock body, and make the anti-theft lock body more miniaturized and multi-functional. In one body, the function can be changed according to the needs to be suitable for some interior door locks and door locks used in specific occasions. The present invention has smaller and thinner overall volume, more stable performance, and higher cost performance. The technical bottleneck of mechanical keys meets the multi-functional needs of customers. The present invention removes the electronic characteristic parts of dual motors, dual circuits, and dual power sources in the lock body, and can realize one-way opening and closing of, for example, balcony doors, bathroom doors, aisle doors, fire doors, etc., or normally open and temporarily close without mechanical locks The needs of special occasions. The adjustment and conversion of the lock body is simple and convenient, the functions are diversified, the appearance is integrated, the specifications and sizes are standardized, the openings on the door are small, and the slotted holes are small, which is conducive to large-scale promotion and use, and avoids the inconvenience of lock replacement and maintenance caused by the incompatibility of various manufacturers and standards. and waste.

In the above description, many specific details have been set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways that are different from those described here, and those skilled in the art can do without departing from the connotation of the present invention. By analogy, the present invention is therefore not limited to the specific embodiments disclosed above.
