Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Below in conjunction with the accompanying drawings, the present invention will be further described with specific embodiments,

As shown in Figures 1-8, a password unlocking handle includes a handle 1, a fixing plate 2 is connected to the handle 1, and an unlocking assembly 10 is arranged between the handle 1 and the fixing plate 2, and is characterized in that , the unlocking assembly 10 includes a square core 3 extending outward from the fixing plate 2, the square core 3 can be rotated relative to the fixing plate 2, and the square core 3 is formed with a handle 1 extending inwardly. The rotating shaft 31 between the fixed plate 2 and the rotating shaft 31 is sleeved with at least one set of cipher wheel 4. The cipher set wheel 4 includes an outer dial wheel 41 and an inner linkage wheel 42 that can be rotated synchronously, and the inner linkage wheel 42 A linkage groove 421 is formed on the rotating shaft 31 , a linkage gap 311 and a limit groove 312 are respectively formed in the rotating shaft 31 , and a movable linkage 5 is arranged in the rotating shaft 31 . The member 5 is respectively formed with a linkage baffle 51 which is located in the linkage gap 311 and can extend into the linkage groove 421, and is located in the limiting groove 312 and can rotate relative to the rotation shaft 31. The limit baffle 52, the rotating shaft 31 is also provided with a spring 6 that makes the linkage baffle 51 have a tendency to pop out of the linkage gap 311, and a spring 6 that makes the limit baffle 52 have a rotation tendency. The handle 1 is also formed with an escape hole 11 aligned with the left half of the limiting groove 312 . Specifically, scale lines are formed on the side end surface of the fixing plate 2, and numbers are formed on the surface of the outer dial wheel 41. Rotate the outer dial wheel 41 to the surface of the number code and align the outer dial with the password. At the position of the scale line on the moving wheel 41, the door can be opened by turning the unlocking handle. When the user rotates the outer dial wheel 41, the inner linkage wheel 42 rotates synchronously with the outer dial wheel 41. When the outer dial wheel 41 rotates to the correct password position, the linkage The member 5 is pushed by the spring 6 in the rotating shaft 31, and the linkage baffle 51 pops out from the linkage gap 311 of the rotating shaft 31 and extends into the linkage groove 421 of the inner linkage wheel 42. When the user rotates the unlocking handle, since the combination wheel 4 rotates with the unlocking handle as a whole, the inner linkage wheel 42 will pass through the extension. The linkage baffle 51 inserted into the linkage groove 421 drives the rotation shaft 31 to rotate, and the rotation of the rotation shaft 31 is the rotation of the square core 3. The square core 3 is inserted into the square steel and connected to the door. At this time, turning the unlocking handle can control the door lock and realize the door opening. When the outer toggle wheel 41 is rotated again, the inner linkage wheel 42 can also press the linkage baffle 51 back into the linkage gap 311 through the linkage groove 421 , and reset the linkage member 5 . When the outer toggle wheel 41 is not rotated to the correct password position, the linkage baffle 51 is always located in the linkage gap 311 and cannot be ejected, and a linkage relationship cannot be formed between the inner linkage wheel 42 and the rotating shaft 31 , at this time, the unlocking handle is rotated, although the combination wheel 4 can rotate with the entire unlocking handle, but because the inner linkage wheel 42 cannot drive the rotation shaft 31 to rotate when rotating, that is, the square The core 3 cannot be rotated, the rotation of the unlocking handle is not ineffective and idling, and the door lock cannot be controlled to unlock. When the user needs to change the unlocking password of the unlocking handle, first turn the outer dial wheel 41 to a position where the password is correct. At this time, since the spring 6 pushes the linkage 5 to move, the limit baffle 52 is also In the limiting groove 312 from the left end to the right end, the left half of the limiting groove 312 will leave a space, and pass the round pin of the same size through the code-escape through hole 11 of the handle 1 and extends into the left half of the limiting groove 312 with a vacant position, the circular pin is in contact with the left end of the limiting baffle 52, and the linkage 5 cannot be reset. At this time, when the user rotates the outer toggle wheel 41, the inner linkage wheel 42 cannot be rotated due to the influence of the linkage baffle 51 extending into the linkage groove 421. There is no synchronous rotation between the toggle wheel 41 and the inner linkage wheel 42, the outer toggle wheel 41 rotates, and the inner linkage wheel 42 does not rotate. The number of the digit code is aligned with the scale line on the fixing plate 2, and the replacement of the unlocking code of the unlocking handle can be completed. After completing the password replacement, pull out the round pin and turn the outer toggle wheel 41 again, the inner linkage wheel 42 restores the synchronous rotation relationship with it, and the linkage baffle 51 can be pressed back through the linkage groove 421 In the linkage gap 311, the linkage member 5 is restored to a resettable state, and the unlocking handle can continue to be used normally.

Further, the end surface of the linkage baffle 51 facing the linkage groove 421 is an arc surface, and the linkage groove 421 is formed by the first convex block 422 formed in the inner linkage wheel 42 in the direction of the rotation shaft 31 . The end surface of the first bump 422 facing the rotating shaft 31 is an arc surface. Specifically, when the user does not rotate the unlocking handle but only rotates the outer toggle wheel 41 , since the inner linkage wheel 42 rotates synchronously, there is a possibility that the first bump 422 and the linkage baffle 51 may The arc surfaces that cooperate with each other, when the inner linkage wheel 42 rotates, the first bump 422 comes into contact with the linkage baffle 51 , and the first bump 422 applies the arc surface to the linkage baffle 51 through its arc. Push and reduce the frictional force generated by the two when they are in contact through the arc surfaces of the two, so that the first bump 422 can smoothly press the linkage baffle 51 back into the linkage gap 311 .

The first clamping notch 71 of the first bump 422 is described. Specifically, the matching resistance coil 7 can increase the friction force between the inner linkage wheel 42 and the rotating shaft 31, so as to prevent the inner linkage wheel 42 from rotating relative to the rotating shaft 31 at will, resulting in When unlocking, rotating the unlocking handle as a whole cannot normally drive the rotation shaft 31 to rotate through the inner linkage wheel 42, so as to avoid the occurrence of the inner linkage wheel 42 directly rotating the linkage baffle 51 directly with the handle. Pressing back into the linkage notch 311 does not drive the rotating shaft 31 to rotate. The cooperation of the first clamping notch 71 and the first bump 422 strengthens the pairing resistance coil 7 and the The connection between the inner linkage wheels 42 .

As shown in FIGS. 5-6 , a non-slip groove 411 is formed on the surface of the outer dial wheel 41 . Specifically, the protective groove 411 can make the user save effort when turning the outer dial wheel 41 , and the anti-slip groove 411 also increases the distance between the outer dial wheel 41 and the handle 1 . Therefore, when the user rotates the whole of the unlocking handle, the handle 1 can effectively drive the combination wheel 4 to rotate accordingly.

The second bump 423 abutting against the limiting end surface 412 . Specifically, the connection between the outer dial wheel 41 and the inner linkage wheel 42 can be realized by the second protrusion 423 abutting against the limiting end surface 412 , and the second protrusion 423 can increase the outer dial The frictional force between the driving wheel 41 and the inner linkage wheel 42 enables better synchronous rotation between the outer toggle wheel 41 and the inner linkage wheel 42 .

As shown in FIGS. 4-6 , between the outer toggle wheel 41 and the inner linkage wheel 42 is a code-changing resistance coil 8 sleeved on the inner linkage wheel 42 , and the code-changing resistance coil 7 is formed with The second clamping notch 81 of the second protrusion 423 can be accommodated. Specifically, the resistance spring ring 8 further increases the frictional force between the outer toggle wheel 41 and the inner linkage wheel 42, so as to avoid the rotation of the outer toggle wheel 41 except when changing codes. In the case where the linkage wheel 42 does not rotate, at the same time, the cooperation between the clamping notch 81 and the second bump 423 reinforces the position of the code changing resistance coil 8 between the outer toggle wheel 41 and the inner linkage wheel 42 .

As shown in FIG. 2 , a retaining ring 9 sleeved on the rotating shaft 31 is provided between the cipher group wheels 4 . Specifically, the retaining ring 9 can block the cipher wheel 4. Since multiple sets of cipher wheels 4 can increase the security of the unlocking handle, more numbers are required for the unlocking handle. Combining to unlock the retaining ring 9 can avoid the situation that the password group wheels 4 interfere with each other due to friction when the user rotates the outer dial wheel 41 to call out the password.

As shown in FIG. 2 and FIG. 7 , a gap is formed between the retaining ring 9 and the rotating shaft 31 , a positioning groove 313 is formed on the rotating shaft 31 , and a positioning groove is formed on the retaining ring 9 to be embedded in the positioning groove The positioning protrusion 91 of the groove 313 . Specifically, because the linkage baffle 51 will protrude from the linkage gap 311 , that is, the linkage baffle 51 will not enter the linkage groove of the inner linkage wheel 42 until it protrudes from the rotating shaft 31 . 421 , a gap is left between the retaining ring 9 and the rotating shaft 31 to prevent the retaining ring 9 from hindering the extension of the linkage baffle 51 . The cooperation between the positioning groove 313 and the positioning protrusion 91 plays a role in fixing the retaining ring 9 on the rotating shaft 31 , so as to avoid the retaining ring 9 from being damaged by the gap between the retaining ring 9 and the rotating shaft 31 . Shaking occurs.

As shown in FIG. 3 , FIG. 7 and FIG. 8 , a coupling groove 314 is formed in the rotating shaft 31 , and a support shaft 53 that can rotate in the coupling groove 314 is formed on the link member 5 . Specifically, the cooperation between the support shaft 53 and the coupling groove 314 provides a support point for the movement of the linkage member 5 in the rotation shaft 31, so that the structure of the unlocking handle is more stable.

Further, a through hole 315 is formed on the side end of the rotating shaft 31 , and the spring 6 is disposed in the linkage through hole 315 and protrudes from both ends of the linkage through hole 315 , and respectively abuts against the linkage through hole 315 . Between the inner linkage wheel 42 and the linkage member 5 . Specifically, one end of the spring 6 abuts against the inner end of the inner linkage wheel 42 , and one end abuts on the side end of the linkage member 5 . When the inner linkage wheel 42 rotates until the linkage groove 421 is aligned When the linkage baffle 51 is formed, the spring 6 can push the linkage member 5 to move in the rotating shaft 31 , so that the linkage baffle 51 pops out of the linkage gap 311 and extends into the linkage groove 421 , the linkage through hole 315 serves to fix the spring 6 .
