Description

Technical Field

[0001] The present invention relates to the technical field of password wheels, and specifically to a password wheel structure with quick reset. Background Art

[0002] A password wheel is a structure that constitutes a roller password lock. Generally, three digital password wheels control the password lock, which is also relatively common in real life and its operation is relatively simple. By turning the password wheel, the lock can be opened when the corresponding password is correct.

[0003] Among them, the publication number is CN213807059, named a password lock, which includes a housing and a password wheel rotatably arranged in the housing and partially exposed outside the housing. The outer peripheral wall of the password wheel has a plurality of password units evenly distributed around its central axis. A scale groove is opened between two adjacent password units. An elastic abutting member is also arranged in the housing. The elastic abutting member includes an abutting block and an elastic member connected to each other. The abutting block abuts against the outer peripheral wall of the password wheel; when the password wheel is rotated, when the position of the scale groove on the password wheel corresponds to the abutting block, one end of the abutting block close to the password wheel extends into the scale groove. An elastic abutting member that abuts against the password wheel is arranged in the housing. The abutting block on the elastic abutting member can provide a certain damping for the rotation of the password wheel, and at the same time can cooperate with the scale groove on the password wheel, so that the preset password unit on the password wheel can accurately stop at the specified position during the rotation process, improving the operability of the password lock operation.

[0004] The above-mentioned prior art can ensure that the password wheel accurately stops at the specified position by using the elastic abutting member. However, when the password wheel needs to be reset after changing the password or other operations that require zeroing, the password wheel still needs to be rotated and reset one by one, and cannot be quickly reset to zero. Its operation convenience is relatively low, and for the disassembly and maintenance of the password wheel, the disassembly and assembly operation process needs to use tools to disassemble small parts one by one, and the operation is relatively complicated. Therefore, we propose a password wheel structure with quick reset to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a password wheel structure with quick reset, so as to solve the problems in the above background art that currently in the market, when the password wheel needs to be rotated and reset one by one after changing the password or other operations that require zeroing, it cannot be quickly reset to zero, its operation convenience is relatively low, and for the disassembly and maintenance of the password wheel, the disassembly and assembly operation process needs to use tools to disassemble small parts one by one, and the operation is relatively complicated.

[0006] To achieve the above object, the present invention provides the following technical solution: A password wheel structure with quick reset, including an installation box, on the upper side of one end of the installation box, an installation cover is bolted and fixed, and a through groove is opened on the upper side of the installation cover, and a password wheel body penetrates through the inside of the through groove;

[0007] It also includes:

[0008] A fixing rod, one end of which is bolted and fixed inside the installation box, and a fixing sleeve is sleeved on the outside of the fixing rod, and an annular groove is opened on the outside of the fixing sleeve, a limiting ring is slidably connected to the inside of the annular groove, and a password wheel body is installed on the outside of the limiting ring, and a locking groove is opened inside the fixing sleeve;

[0009] An installation frame is installed on the side of the installation box away from the fixing rod, and a rotating shaft is rotatably connected to the inside of the installation frame, and the end of the rotating shaft is elastically connected to the installation frame through a scroll spring;

[0010] A transmission disc is installed on the outside of the rotating shaft, and a tooth block a is connected to the outside of the transmission disc, and a positioning groove is opened on the outside of the end of the transmission disc away from the tooth block a;

[0011] A tension spring, one end of which is connected to the upper side of the installation frame, and the other end of the tension spring is connected to a positioning rod, and a magnet a is installed at the upper end of the positioning rod;

[0012] A fixing ring is installed on the outside of the password wheel body, and a gear b is connected to the outside of the fixing ring, and the gear b is meshed with the tooth block a.

[0013] Preferably, a compression spring is connected to the outside of the installation box, and one end of the compression spring is connected to an adjusting rod, and a magnet b is connected to the lower side of the end of the adjusting rod extending into the installation box.

[0014] Preferably, an adjusting spring is connected inside the fixing rod, and one end of the adjusting spring is connected to a moving rod, and a transmission rod is hingedly connected to the outside of the moving rod, and a locking rod is hingedly connected to the end of the transmission rod away from the moving rod.

[0015] Preferably, the fixing sleeve is of a circular ring structure, and the fixing sleeve can slide on the fixing rod. This design can smoothly sleeve the fixing sleeve onto the fixing rod to achieve the installation and fixation of the password wheel.

[0016] Preferably, the tooth blocks a and the gears b are distributed at equal angles at the connection between the transmission disk and the fixed ring, and the transmission disk forms a rotating structure with the mounting frame through the rotating shaft. This design can drive the transmission disk to rotate when the fixed ring rotates, thereby realizing the linkage between the two.

[0017] Preferably, one side of the lower end of the positioning rod is an inclined structure, and the positioning rod and the positioning groove are engaged with each other, and the positioning grooves are distributed at equal angles on the outside of the transmission disk. This design can ensure that the positioning rod can push the positioning rod when the positioning groove follows the unidirectional rotation movement of the transmission disk, thereby preventing the positioning rod from blocking the positioning groove.

[0018] Preferably, the positions of the magnet a and the magnet b are arranged in one-to-one correspondence, and the magnet a and the magnet b are magnets of different poles. This design can utilize the attraction between the magnets to drive the positioning rod and adjust the position of the positioning rod.

[0019] Preferably, the adjusting rod is a "cross" shaped structure, and the adjusting rod and the mounting box form an elastic structure through the compression spring. This design can flexibly drive the adjusting rod to move and adjust the relative position between magnet a and magnet b.

[0020] Preferably, the moving rod is a "cross" shaped structure, and the moving rod forms an elastic structure with the fixing rod through the adjusting spring, and the moving rod and the locking rod distributed in a vertical direction are connected through the transmission rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The fast reset code wheel structure is provided with a transmission disk and an adjustment rod. The transmission of the meshing tooth block a and the tooth block b can realize the linkage between the transmission disk and the code wheel. Therefore, when the code wheel rotates, it can drive the transmission disk to rotate synchronously and push the positioning rod to move to ensure the smooth rotation of the transmission disk. When the positioning rod and the positioning groove at the adjacent position thereof correspond to each other, due to the elastic force of the tension spring, the positioning rod can be stuck in the positioning groove to limit the position of the transmission disk, thereby limiting the position of the code wheel. By using this structure, the transmission disk can accurately stay at the specified position during the rotation process, thereby allowing the code wheel body to accurately stay at the specified position during the rotation process without manual groping and fine-tuning. At the same time, when the transmission disk rotates, the vortex spring at the end of the rotating shaft is used to store force and press the adjustment rod so that the positions of magnet a and magnet b correspond to each other, and the magnets with different polarities attract each other, pulling the positioning rod out of the positioning groove. At this time, the transmission disk and the code wheel can be unlocked, and the vortex spring can control the transmission disk to drive the code wheel to quickly return to zero and reset, without the need for manual toggling and resetting one by one.

[0023] (2) The password wheel structure with quick reset is provided with a moving rod. Just press the moving rod into the fixed rod, push the transmission rod to drive the locking rod to engage in the locking groove at the corresponding position, lock the position of the fixed sleeve, and thus lock the assembly of the password wheel. When the fixed rod is bolted to the installation box, due to the blockage of the installation box, the moving rod is prevented from moving by itself. Without any other operations, the assembly of the password wheel can be achieved, and the operation is convenient and fast. When disassembling the password wheel, just remove the fixed rod from the installation box. Due to the elastic force of the adjusting spring, the moving rod can be removed, thereby controlling the transmission rod to drive the locking rod out of the locking groove, unlocking the fixed sleeve, and thus unlocking the password wheel. Its disassembly and assembly are more convenient. Description of the Drawings

[0035] Embodiment 1

[0036] Since when the password wheel is in the steps of changing the password or other operations that need to be reset after zeroing, it is still necessary to rotate and reset the password wheel one by one, and it cannot be quickly reset to zero, and the convenience of its operation is relatively low. Therefore, to solve this technical problem, this embodiment further includes an installation box 1. On the upper side of one end of the installation box 1, an installation cover 2 is bolted and fixed. And a through groove 3 is opened on the upper side surface of the installation cover 2, and a password wheel body 8 penetrates through the inside of the through groove 3; a fixing rod 4, one end of which is bolted and fixed inside the installation box 1, and a fixing sleeve 5 is sleeved on the outer side of the fixing rod 4. And an annular groove 6 is opened on the outer side of the fixing sleeve 5. A limiting ring 7 is slidably connected to the inside of the annular groove 6, and a password wheel body 8 is installed on the outer side of the limiting ring 7. A locking groove 25 is opened on the inner side of the fixing sleeve 5; an installation frame 9 is installed on the side of the installation box 1 away from the fixing rod 4 inside the installation box 1, and a rotating shaft 11 is rotatably connected to the inside of the installation frame 9. And the end of the rotating shaft 11 is elastically connected to the installation frame 9 through a scroll spring 10; a transmission disk 12 is installed on the outer side of the rotating shaft 11, and a tooth block a 13 is connected to the outer side of the transmission disk 12. And a positioning groove 14 is opened on the outer side of the end of the transmission disk 12 away from the tooth block a 13; a tension spring 15, one end of which is connected to the upper side of the installation frame 9, and the other end of the tension spring 15 is connected to a positioning rod 16, and a magnet a 17 is installed on the upper end of the positioning rod 16; a fixing ring 26 is installed on the outer side of the password wheel body 8, and a gear b 27 is connected to the outer side of the fixing ring 26, and the gear b 27 is meshed with the tooth block a 13. A compression spring 18 is connected to the outer side of the installation box 1, and one end of the compression spring 18 is connected to an adjusting rod 19, and a magnet b 20 is connected to the lower side of the end of the adjusting rod 19 extending into the installation box 1.

[0037] The connection between the transmission disk 12 and the fixed ring 26 is respectively provided with tooth blocks a13 and gears b27 at equal angles, and the transmission disk 12 forms a rotating structure with the mounting frame 9 through the rotating shaft 11. One side of the lower end of the positioning rod 16 is an inclined structure, and the positioning rod 16 and the positioning groove 14 are mutually engaged, and the positioning groove 14 is distributed at equal angles on the outer side of the transmission disk 12. The positions of the magnet a17 and the magnet b20 are arranged one by one, and the magnet a17 and the magnet b20 are magnets of different poles. The adjustment rod 19 is a "cross" shaped structure, and the adjustment rod 19 forms an elastic structure with the mounting box 1 through the compression spring 18.

[0038] The working principle of this embodiment is: Figure 1 The entire device shown is installed in the use area, and the password wheel body 8 is exposed, and the password wheel body 8 is turned to combine Figure 7 As shown, the limiting ring 7 installed on the inner side of the code wheel body 8 slides in the annular groove 6 to realize the rotation of the code wheel body 8 and set the code. At the same time, when the code wheel body 8 rotates, the fixing ring 26 installed on the outer side can be controlled to rotate. Figures 2 - 6 As shown, the gear b27 installed on the outside of the fixing ring 26 is meshed with the tooth block a13 installed on the transmission plate 12, so the transmission plate 12 can be driven to rotate. When the transmission plate 12 rotates, the positioning rod 16 can be pushed to make the positioning rod 16 gradually move upward, and the positioning rod 16 stretches the tension spring 15 to store force, and the positioning rod 16 gradually moves out of the positioning groove 14, so as to ensure that the transmission plate 12 can rotate smoothly through the rotating shaft 11. The vortex spring 10 connected to the end of the rotating shaft 11 rotates synchronously to store force. When the position of the positioning rod 16 corresponds to the position of the next positioning groove 14, the tension spring 15 can control the positioning rod 16 to move down and reset, and the positioning rod 16 is stuck in the positioning groove 14, and the transmission plate 12 is limited at a fixed angle, so that the transmission plate 12 During the rotation process, it can accurately stay at the specified position, so that the code wheel body 8 can accurately stay at the specified position during the rotation process. After the three code wheel bodies 8 are set, it is necessary to perform zero reset processing. The adjustment rod 19 can be pressed to store force on the compression spring 18. At the same time, the adjustment rod 19 controls the movement of the magnet b20. When the position of the magnet b20 corresponds to the position of the magnet a17, the magnets a17 and b20 with different polar distributions attract each other, and the positioning rod 16 is controlled to move upward, and the positioning rod 16 is moved out of the positioning groove 14. At this time, the vortex spring 10 can control the rotating shaft 11 to drive the transmission disk 12 to reset and rotate, thereby controlling the code wheel body 8 to reset and rotate, and realizing the rapid reset and zeroing of the code wheel body 8;

[0039] Example 2

[0040] For the disassembly and maintenance of the code wheel, the disassembly and assembly process requires the use of tools to disassemble the small accessories one by one, which is relatively complicated. Therefore, in order to solve this technical problem, the present embodiment also includes an adjustment spring 21 connected to the inside of the fixed rod 4, and one end of the adjustment spring 21 is connected to the moving rod 22, and the outer side of the moving rod 22 is hingedly connected to the transmission rod 23, and the end of the transmission rod 23 away from the moving rod 22 is hingedly connected to the locking rod 24.

At this time, the pressure of the installation box 1 on the moving rod 22 can be released, and the adjustment spring 21 in the stored force state can control the moving rod 22 to move outside the fixing rod 4, thereby pulling the transmission rod 23 to rotate, and then controlling the locking rod 24 to move inside the fixing rod 4, and moving the locking rod 24 out of the locking groove 25 can release the lock on the fixing sleeve 5, and the fixing The fixed sleeve 5 is removed from the fixed rod 4, thereby realizing the disassembly of the code wheel body 8. When installing the code wheel body 8, it is only necessary to sleeve the fixed sleeve 5 on the specified external position of the fixed rod 4, press the moving rod 22, the moving rod 22 stretches and accumulates force on the adjusting spring 21, and controls the transmission rod 23 to drive the locking rod 24 to move in the direction of the fixed sleeve 5, and the locking rod 24 is stuck in the locking groove 25 to lock the fixed sleeve 5. The fixed rod 4 is placed in the installation box 1 and fixed with bolts. Due to the obstruction of the installation box 1, the moving rod 22 is prevented from moving by itself, thereby realizing the installation of the code wheel body 8.
