The bottom of the sheet 3 is provided with grooves in the horizontal direction. A pressing plate 4 is pressed above the linkage block 2 to exert a downward force on the linkage block 2 .

A pressing plate 4 is installed inside the mechanical password device, and an operating rod 15 is installed on the top of the pressing plate 4. One end of the operating rod 15 is fixedly connected with the pressing plate 4, and the other end extends toward the direction of the casing 14; A locking mechanism is provided, and four engaging blocks 7 are provided at the bottom of the pressing plate 4, and the engaging blocks 7 are in contact with a locking tongue plate 6; one end of the locking tongue plate 6 is provided with a locking tongue 5; the locking tongue Square protrusions are arranged horizontally on both sides of the plate 6 . The square protrusions of the deadbolt plate 6 are in contact with the engaging block 7 , and the deadbolt plate 6 can be linked with the pressing plate 4 when moving away from the bolt 5 . The bottom of the deadbolt plate 6 is provided with three bosses 8 , and the bosses 8 have the function of locking the deadbolt plate 6 . A limit block 9 is installed below the deadbolt plate 6, and the limit block 9 is connected with the boss 8 at the bottom of the deadbolt plate 6, and the longitudinal movement of the deadbolt plate 6 is restricted by the interference between the limit block 9 and the boss 8 . A reset protrusion is provided at one end of the lock tongue plate 6 away from the lock tongue 5 , and a reset spring 13 is provided on the reset protrusion.

As shown in FIGS. 3 and 4 , the locking structure in the device is arranged at one end away from the lock tongue 5 and is fixedly connected with the pressing plate 4 , and the locking mechanism can move with the movement of the pressing plate 4 . The locking mechanism of the device is arranged inside the mechanical password device, and the locking mechanism of the device also includes a locking member 10 and a locking member 11. One end of the locking member 10 is connected to the pressing plate 4, and the other end is a locking portion 12. , the shape of the locking portion 12 is a structure with a protruding shape, preferably a triangle. The locking member 11 in the locking mechanism is also arranged inside the housing 14 , and the locking member 11 has a locking portion that cooperates with the locking portion 12 , and two locking portions are provided on the locking portion. , the locking part has the movement of clamping to the middle, so as to realize the locking of the locking part by the locking part.

When you need to scramble the password, you only need to turn the code disc 1, because there is a spring between the limit blocks 9, so under the interference of external force, the limit block 9 has the force against the spring to realize the limit block 9 from the lock plate 3. push out in the groove.

As shown in FIG. 6 , the return spring 13 of the device is arranged inside the casing 14 . One end of the return spring 13 is in contact with the deadbolt plate 6 , and the other end is connected with the casing 14 . The return spring 13 The pressing plate 4 is provided with a driving force in the second state. The return spring 13 can restore the deadbolt plate 6 and the pressing plate 4 to their original positions after the password reset is completed.

Principle and process of use

In the process of resetting the password, the mechanical password device in this device first rotates the password plate 1 to rotate the password plate 1 to the correct password, and drives the groove plate at the bottom to rotate by selecting the password plate 1. When the passwords are all correct , the grooves of the groove plate will all be aligned with the central axis of the device. When the grooves are all facing the central axis, because the shape of the limit block 9 matches the shape of the groove plate, the gap between the limit blocks 9 Under the action of the spring, the limit blocks 9 will all enter the corresponding grooves. At this time, the limit blocks 9 lose their limiting effect on the deadbolt plate 6, and the deadbolt plate 6 is only subject to the direction of the return spring 13 at this time. As for the force of the locking tongue 5 , because the pressing plate 4 and the locking tongue plate 6 are connected by the engaging block 7 , the pressing plate 4 is also subjected to the force of the return spring 13 .

Manually move the operating lever 15 on the pressing plate 4, by driving the pressing plate 4 to resist the force of the reset spring 13, and then the locking portion 12 of the locking mechanism encounters the protrusion of the locking portion when it enters the locking portion, and the protrusion drives the locking portion. The locking parts at both ends of the device shrink toward the middle to lock the locking part 12 in the buckle part. At this time, the force on the operating lever 15 can be removed, so that it is not necessary to apply force to the operating lever 15 all the time in the process of resetting the password. .

When the password reset is completed, manually turn the operating lever 15 on the pressing plate 4 again to squeeze the locking portion 12 against the protrusion of the locking portion again. Due to the structure of the push-type lock, the locking portion will lose its locking force. . When the push-type lock loses its force on the locking portion 12 , the locking portion 12 will move away from the locking portion under the action of the return spring 13 . Finally, the pressing plate 4 and the deadbolt plate 6 return to their original positions under the action of the return spring 13, and finally the password is scrambled to complete the password reset of the mechanical combination lock device.

Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And the obvious changes or changes derived from this are still within the protection scope of the present invention.
