However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0038] Example 1: See Figures 1 to 10 A mechanically structured password disc brake lock comprises a housing 1 and a password lock assembly 2 disposed on the housing 1. The password lock assembly 2 comprises a lock tongue assembly 21 disposed on the housing 1 and a plurality of password disk groups 22. The plurality of password disk groups 22 are provided with a connecting rod 23, and the connecting rod 23 is provided with a password shaft 24 corresponding to each password disk group 22. The housing 1 is provided with a pressing assembly 25 for opening and closing the lock tongue assembly 21, and the housing 1 is provided with a starting device 26 for changing the password of the password disk group 22. The utility model maintains a purely mechanical structure while maintaining keyless opening and closing, making operation simpler and more convenient. More importantly, this method helps reduce the risk of dust and mud entering the interior during frequent outdoor use, thereby reducing the occurrence of malfunctions and greatly improving the service life, making it more suitable for use.

[0039] When the password on the password disk group 22 is correct, the pressing component 25 is activated to cause the pressing component 25 to move to one side, and then press the lock tongue component 21. When the pressing component 25 is released, the pressing component 25 will jam the lock tongue component 21, and the lock tongue component 21 will be locked. When the pressing component 25 is pressed again, the pressing component 25 will no longer jam the lock tongue component 21, and the lock tongue component 21 will be unlocked.

[0040] Example 2: It can be explained based on Example 1, as shown in Figures 1 to 10As shown, the lock tongue assembly 21 includes a lock tongue rod 211 that is arranged on the shell 1 and can slide back and forth. The lock tongue rod 211 is provided with a reset spring 212, and the lock tongue rod 211 can be automatically reset by the reset spring 212. A limiting groove 213 and a card slot 214 are provided on the lock tongue rod 211. The limiting groove 213 corresponds to one side of the combination lock assembly 2 in the shell 1, and a limiting pin 215 is provided in the shell 1. The lock tongue rod 211 moves back and forth in the shell 1 with the limiting pin 215 so that the limiting pin 215 moves in the limiting groove 213, which is beneficial to preventing the lock tongue rod 211 from sliding a specified distance, and the card slot 214 is located on the lock tongue rod 211 away from the reset spring 212. The pressing assembly 25 is engaged in the card slot 214 to achieve a locked state when the lock tongue rod 211 is pressed and the external force is released.

[0041] Example 3: This can be explained based on Example 1 or Example 2, such as Figures 1 to 10 As shown, the pressing assembly 25 includes a card plate 251 arranged inside the shell 1, and a return spring 252 for resetting the card plate 251 is provided on one end of the card plate 251, and a clamping portion 253 is provided at the other end of the card plate 251. The clamping portion 253 can lock the lock tongue assembly 21, and a pressing member 254 is provided on the shell 1, which can drive the card plate 251 to be moved horizontally. In this way, when the pressing member 254 is activated by external force, the card plate 251 will move toward the side of the return spring 252, and at the same time, the return spring 252 can be compressed, which is conducive to the activation of the lock tongue assembly 21, and when the pressing member 254 is released, the lock tongue assembly 21 will be locked. The latch 251 is unlocked by releasing the button 2541 and the latch 251 is unlocked by releasing the button 2541.

[0042] Example 4: This can be explained based on Example 1, Example 2, or Example 3. Figures 1 to 10As shown, the password disk groups 22 in this embodiment adopt four password disks, and correspondingly, the password shafts 24 are also four, and each password disk has a corresponding password shaft 24. The password shaft 24 is arranged between the connecting rod 23 and the password disk, and a compression spring 231 is sleeved on one end of the connecting rod 23. One end of the compression spring 231 contacts the password shaft 24. This password shaft 24 will contact the compression of the compression spring 231, and the other end of the compression spring 231 abuts against the inner wall of the shell 1, which is conducive to resetting the password shaft 24. A bouncing lock 221 for bouncing up the password disk groups 22 is provided inside the shell 1. This arrangement is more conducive to not only bouncing up the password disk, but also to pressing the switch of the component 25.

[0043] like Figures 1 to 10 As shown, each combination disk has a central hole at its center, and grooves are evenly spaced around its circumference. Correspondingly, each combination shaft 24 includes a central shaft 241 and a circular disc 242 mounted on the central shaft 241. The circular disc 242 has a notch 243, and evenly spaced protrusions 244 are distributed on the outer surface of the central shaft 241. Multiple protrusions 244 form a shaft body, and the central hole of the combination disk and the shaft body are clearance-fitted, which facilitates the movement of the combination disk. In this embodiment, each combination disk is provided with numbers from 0 to 9, which are used to change the combination and open and close the lock.

[0044] like Figures 1 to 10As shown, the bounce lock 221 includes a lock plate 2211 and a spring plate 2212 arranged inside the shell 1, and a return spring 2213 is provided between the lock plate 2211 and the inner wall of the shell 1 (and two return springs 2213 are used in this embodiment), which is conducive to the bounce of the lock plate 2211, and a wave plate is provided on the lock plate 2211 to match the notch 243 of the disk 242 on the corresponding password shaft 24, and a mounting position for placing the password disk is formed between adjacent wave plates (and a notch in this embodiment), and the wave plate and the notch 243 of the disk 242 are engaged with each other, and a spring plate is provided on the spring plate 2212 for each password disk to bounce up, which is conducive to the rotation of the disk 242, and a lock plate is provided on the lock plate 2211, and The card plate 251 is provided with a matching groove for matching with the lock plate. When in use, the spring plate on the shrapnel 2212 can make the corresponding password disk pop up. When the lock plate is not in the matching groove, the pressing member 254 cannot be pressed, so the subsequent lock tongue assembly 21 cannot be started. When all the password disks are rotated to the correct password, the wave plate and the notch 243 of the disc 242 are engaged with each other. At this time, the lock plate is located in the matching groove, and the pressing member 254 can be pressed. Then, the pressing member 254 is activated by external force, which will cause the card plate 251 to move toward the side of the return spring 252 and compress the return spring 252 at the same time, which is conducive to the activation of the lock tongue assembly 21. When the pressing member 254 is released, the lock tongue assembly 21 is stuck.

[0045] like Figures 1 to 10 As shown, the starting device 26 includes a push button 261 arranged on the other end of the connecting rod 23, the other end of the push button 261 is arranged on the shell 1, and a mounting hole is opened on the shell 1 corresponding to the push button 261, and a detachable and installable fixing cover 262 is provided on the mounting hole, and a running hole 263 is provided on the shell 1 for the push button 261 to be stuck after being pushed, and in this embodiment, the running hole 263 includes a horizontal track and a vertical track connected to the horizontal track, so that the push button 261 can move back and forth in the horizontal track and the vertical track, and in this embodiment, a fixing hole is opened in the fixing cover 262, and a screw or bolt is installed in the fixing hole, and the fixing cover 262 can be fixed to the shell 1 by the screw or bolt. This arrangement facilitates disassembly and installation.

[0046] During use, when the password needs to be changed, first remove the fixed cover 262, then manually push the push button 261 to one side of the vertical track and enter the vertical track, which will cause the connecting rod 23 to move to the side of the compression spring 231, which is conducive to compressing the compression spring 231. At this time, the password disk can be rotated independently of the password shaft 24. If the password disk is turned to any number, then push the button 261 again to let the password shaft 24 return to the position corresponding to the position on the password disk, so that the password is replaced.

[0047] Example 5: This can be explained based on Example 1, Example 2, Example 3, or Example 4. Figures 1 to 10 As shown, the housing 1 includes a shell 11, a cavity is provided in the shell 11, and the connecting rod 23 and the password shaft 24 are installed in the cavity, and a number of the lock tongue components 21, the password disk group 22 and the push assembly 25 are exposed, which is convenient for the user's later manual operation, and a cover plate 12 is provided on the shell 11 at the position of the password disk group 22. This arrangement is reasonable and convenient for disassembly and installation. It should be noted that the shell 11 is provided with a drainage hole 13. This arrangement is more conducive to the drainage of the accumulated water after outdoor use, especially when there is water accumulation, through the drainage hole 13 to avoid erosion of internal components. The number of drainage holes 13 can be determined according to actual conditions, which is more conducive to meeting customization according to needs and is also more conducive to drainage.

[0048] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and screws in the existing technology, which will not be described in detail here.

[0049] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model.
