DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] Specific embodiments are given below.
[0023] Please refer to Figures 1-3The utility model discloses a modular independent number password wheel, including the password wheel body 1, the equidistance of password wheel body 1's circumference side is equipped with a plurality of assembly slot 2, the assembly slot 2 is assembled with the apron 201, the assembly slot 2 is assembled with the number block 3, the apron 201 is equipped with the through -hole 2011 for the number block 3's through, the assembly slot 2 is equipped with two groups of lock catch mechanism 4 for fixing number block 3 in symmetry, the lock catch mechanism 4 includes the lock bar 5 that is set in the assembly slot 2 through the swivel lever, the lock bar 5's one end is the lock head 501, the other end is the unlocking warping bar 502, the number block 3 is equipped with the lock groove 301 with the lock head 501 cooperation, the unlocking warping bar 502 and the assembly slot 2 between the end are equipped with the first spring 6, the lock head 501 one side is equipped with the drive inclined plane 5011, the number block 3 one end is equipped with the arc chamfer 303 with the drive inclined plane 5011 cooperation;When working, the number block 3 and the password wheel body 1 are mostly integrally formed when producing the traditional password wheel, such as adopting secondary injection molding to integrate the number and the password wheel, or filling in the number recess of the password wheel body through ink dotting, in this way, once the number part appears flaws in the production process, such as uneven injection, ink dotting blur, etc., the whole password wheel body 1 will be scrapped, and the number block 3 in the utility model is designed as an independent individual, when installing, the user holds the independent number block 3, and gently pushes into the assembly slot 2 along the drive inclined plane 5011 of the lock head 501, in the process, the arc chamfer 303 of the number block 3 contacts the drive inclined plane 5011, is guided by the inclined plane, exerts a lateral thrust on the lock head 501, makes it rotate around the swivel lever, and compresses the first spring 6, when the number block 3 is accurately positioned in the lock groove 301 after deepening, the first spring 6 resets rapidly depending on the elastic force, pushes the lock head 501 into the lock groove 301, and the number block 3 is thus firmly in the assembly slot 2. Due to the drawbacks of the traditional integral molding method, enterprises face high production costs, a large amount of raw materials are wasted due to number flaws, and rework is frequent. The number block 3 of the utility model can be produced and detected separately, the quality is controlled at the source, the yield is greatly increased, the raw material waste and rework cost are greatly reduced, and the production efficiency is significantly improved. From the user use dimension consideration, the independent number block 3 also brings great convenience to daily use. If a certain number is not clear due to long-term wear or needs to change the password, the entire device does not need to be replaced like a traditional password wheel, but only needs to hold a new number block 3 and operate according to the above convenient process. It can be replaced in a few seconds, greatly saving the user's time and effort, and the convenience is unparalleled, greatly improving the user experience.
[0024] Further, the number block 3 is fixedly provided with a number boss 302; in actual use, whether the indoor light is bright or the light is dim at night, the finger lightly touches the number boss 302, and the tactile sensation can clearly outline the digital profile on the number block 3; when visually examining, the number boss 302 is more eye-catching than the ordinary plane number in the protruding shape, and the matched number boss 302 always plays a role, helping the user to accurately identify the number, avoiding misjudgment due to light, vision and other problems, significantly improving the digital identification accuracy and convenience, and optimizing the overall use experience.
[0025] Further, the unlocking mechanism 7 for unlocking the lock catch mechanism 4 is assembled in the assembly groove 2, the unlocking mechanism 7 comprises an unlocking rod 701 slidingly and penetratingly arranged on the cover plate 201, a limiting portion 7011 is fixedly arranged on the unlocking rod 701 in the assembly groove 2, and the bottom end of the unlocking rod 701 abuts against the top of the unlocking rocker 502 of the lock rod 5; in operation, when the number block 3 needs to be replaced, this process takes full advantage of the independence of the number block 3 and the structure design matched therewith, the unlocking rod 701 is lightly pressed and steadily moves downward along the preset path, the bottom end abuts against the top of the unlocking rocker 502, downward pressure is applied to the unlocking rocker 502 in the moving process, the unlocking rocker 502 is forced to overcome the elastic force of the first spring 6, the lock head 501 is reversely rotated around the rotating rod, the lock head 501 is separated from the number block 3, the unlocking is completed, and the unlocking mechanism 7 makes the number block 3 replacement operation simple and fast, without professional skills and complicated tools, the unlocking and replacement can be realized by single pressing operation, and the difficulty and cost of later maintenance are greatly reduced.
[0026] Further, the second spring 8 is fixedly assembled in the assembly groove 2 at a position directly below the number block 3, and the top plate 9 is fixedly arranged at one end of the second spring 8 close to the number block 3; in operation, when the number block 3 is disassembled through the unlocking mechanism 7, in the process of previously installing the number block 3 into the assembly groove 2, the bottom of the number block 3 extrudes the top plate 9, the top plate 9 compresses the second spring 8, the second spring 8 stores elastic potential energy, and when the number block 3 is disassembled, the previously stored elastic potential energy is released, the second spring 8 pushes the top plate 9 by virtue of the elastic force of the second spring 8, and the top plate 9 in turn pushes the number block 3 upward and out of the assembly groove 2, thereby providing great help for disassembling the number block 3, making the whole operation process more smooth and efficient, and bringing a better product experience to the user.
