An axially disposed sleeve groove 523 is disposed inside the shaft sleeve 520, fits over the number lock shaft 300, and has a first end 521 adjacent to the knob cylinder 200 and a second end 522 away from the knob cylinder 200. The second end 522 passes through the character wheel 400 corresponding to the variable number member 500. Viewed at different angles, the first end 521 is proximate to the first end 310 and the second end 522 is remote from the first end 310. The sleeve groove 523 is formed on the inner surface of the sleeve groove 523 and preferably extends from the end of the second end 522 toward the first end 521.

3A and 3B, the variable horn 510 is disposed radially outward from the first end 521 of the shaft sleeve 520, and is detachably engaged with the corresponding variable member 500. The character wheel recess 450 of the character wheel 400. In the embodiment shown in FIG. 3C , the character wheel recess 450 further includes an engaging portion 458 . The variable horn 510 further includes a locking protrusion 518 , and the engaging protrusion 518 is detachably engaged with the engaging portion 458 . The engaging portion 458 can be a notch formed outward from the inner surface of the character wheel 400.

As shown in FIG. 3A and FIG. 3B, the axial movement device 600 is disposed at the second end portion 320, and includes a force receiving member 621 extending from the force receiving member hole 116 out of the housing 100. More specifically, the axial movement device 600 includes a rotating member 620 and an axial moving member 610. The rotating member 620 is disposed on the second end portion 320 so as to be rotatable relative to the number locking shaft 300. The rotating member 620 has a first inclined surface 622 facing one side of the rotating button cylinder 200 (ie, close to the first end portion 310). The rotating member 620 has a force receiving member 621. The axial moving member 610 is disposed on the shaft sleeve 520 and the rotating portion of the indexing member 500 farthest from the rotating cylinder 200 (that is, farthest from the first end portion 310) in such a manner as to be axially movable relative to the number locking shaft 300. Between pieces 620.

As shown in the embodiment shown in Figures 3A and 3B, the displacement return member 700 is disposed at the most The indexing member 500 of the proximal button cylinder 200 (i.e., closest to the first end portion 310) is interposed between the first end portion 310. Wherein, when the plurality of character wheels 400 are respectively rotated to the correct number positions, the sleeve grooves 523 (see FIG. 3B) of each of the index members 500 correspond to the adjacent shaft protrusions 330 in the axial position, subject to The force member 621 can be driven by the first external force to cause the axial movement device 600 to push the plurality of change horns 510 out of the character wheel recesses 450 (see FIG. 3A), the number lock 900 is in a variable number state, and the knob cylinder 200 can be subjected to The second external force drives the rotation. At this time, the displacement returning member 700 provides a force away from the first end portion 310 to act on the plurality of indexing members 500. When at least one of the plurality of character wheels 400 is not rotated to the correct number position, the shaft protrusion 330 limits the movement of the adjacent index member 500 in the axial position, and restricts the plurality of the variable cylinders 510 from being separated by the character wheel recesses 450. The combination lock 900 is in an immutable state, and the shaft projection 330 restricts the movement of the combination lock shaft 300 in the axial position to prevent the rotary cylinder 200 from rotating. More specific actions are detailed below.

3A and 3B, when the plurality of character wheels 400 are respectively rotated to the correct number position, because the sleeve groove 523 (see FIG. 3B) of each of the index members 500 and the adjacent shaft protrusions The 330 corresponds in the axial position, so the indexing member 500 can avoid the restriction of the axial movement of the shaft protrusion 330 by the sleeve groove 523. Therefore, when the force receiving member 621 is driven by the first external force to rotate the rotating member 620 from the first position 601 to the number lock shaft 300 as shown in FIG. 4A to the second position 602 as shown in FIG. 5A, the axial movement is performed. The piece 610 is displaced to move axially toward the first end 310 due to abutment with the first bevel 622. Moreover, since the axial moving member 610 abuts the transposing member 500 farthest from the first end portion 310, and the adjacent transposing members 500 abut each other, the entire transposing member 500 is thereby axially moved. The member 610 pushes the horn 510 out of each of the character wheel recesses 450 (see FIG. 3A), or more specifically, the snap protrusion 518 is engaged with the engaging portion 458 as shown in FIG. 4B, as shown in FIG. 5B is separated from the engaging portion 458, so that the combination lock 900 is in a variable number state.

In this embodiment, the displacement return member 700 is a spring that is compressed as the index member 500 is urged toward the first end portion 310 by the axial moving member 610 to provide a deformation-induced away from the first end portion 310. The force acts on the indexing member 500. When the first external force applied to the force receiving member 621 disappears, the force acting on the indexing member 500 away from the first end portion 310 causes the indexing member 500 to move away from the first end portion 310 to return to the original position.

On the other hand, if any of the plurality of character wheels 400 is not rotated to the correct number position The shaft protrusion 330 restricts the axial movement of the indexing member 500, and the adjacent numbering members 500 abut each other, so that all of the indicator members 500 are unable to move axially, which is associated with the indexing member 500. The axial movement of the abutting axial moving member 610 is limited. At this time, even if the force receiving member 621 is subjected to the first external force, the rotating member 620 is not driven to rotate due to the abutting relationship of the first inclined surface 622 and the axial moving member 610.

Further, the variable lock cylinder 800 of the present invention includes the above number lock shaft 300, a plurality of character wheels 400, a plurality of index members 500, an axial movement device 600, and a displacement recovery member 700. For the number lock 900 using the variable lock cylinder 800 of the present invention, when the user wants to change the set unlock number, only the components of the variable lock cylinder 800 itself need to be utilized, and it is not necessary to use an external pin as in the prior art. And other devices. In this way, the convenience in use can be improved. On the other hand, in the embodiment shown in FIG. 2, since the force receiving member 621 extends from the force receiving member hole 116 out of the top surface 110 of the housing 100, that is, the same as the word wheel 400 exposing the housing 100. By. Therefore, the user can apply an external force to the force receiving member 621 by dialing or the like, so that the number lock 900 is in a variable number state to change the number, and the convenience in use is improved.

On the other hand, as shown in the embodiment shown in FIGS. 4A and 6, the cylindrical surface 210 of the knob cylinder 200 has a knob cylinder recess 230, and the first end portion 310 is detachably engaged with the knob cylinder recess 230. . When the plurality of character wheels 400 are respectively rotated to the correct number positions, since the sleeve grooves 523 (see FIG. 3B) of each of the index members 500 correspond to the adjacent shaft protrusions 330 in the axial position, the shaft The rod projection 330 can move axially in the sleeve groove 523. Further, the side of the button cylinder recess 523 is substantially inclined with respect to the first end portion 310, so when the knob cylinder 200 is driven by the second external force to rotate from the embodiment shown in FIG. 4A to the embodiment shown in FIG. The first end portion 310 is stacked by the side of the knob cylinder recess 523 away from the knob cylinder recess 523, thereby causing the number lock shaft 300 to move axially. In other words, when the plurality of character wheels 400 are respectively rotated to the correct number positions, the shaft protrusions 330 do not interfere with the rotation of the knob cylinder 200, that is, the knob cylinder 200 can be driven by the second external force to be rotated by the embodiment shown in FIG. 4A. To the embodiment shown in FIG. 6.

In the embodiment shown in FIGS. 4A and 6, the displacement returning member 700 is a spring that is compressed when the number lock shaft 300 is moved toward the indexing member 500 by the side of the rotary cylinder recess 523. The force generated away from the sign member 500 based on the deformation acts on the first end portion 310. When the second external force applied to the knob cylinder 200 disappears, the distance acting on the first end portion 310 becomes changed. The force of the number member 500 causes the first end portion 310 to move away from the index member 500 to return to its original position.

When at least one of the plurality of character wheels 400 is not rotated to the correct number position, the shaft protrusion 330 cannot enter the sleeve recess 523, thereby restricting the movement of the number lock shaft 300 in the axial position. At this time, even if the knob cylinder 200 is subjected to the second external force, the knob cylinder 200 is not driven to rotate due to the abutment relationship between the knob cylinder recess 523 and the first end portion 310.
