Description

Technical Field

[0001] The utility model relates to the technical field of watch pull bars, and in particular to a watch pull bar anti-overturning device. Background Art

[0002] The stem of a mechanical watch with a calendar mechanism usually has three gears: "0", "1", and "2". When the watch is in use, the stem can be pushed and pulled to put it in different gears, and then the different functions of the watch can be realized by rotating the crown. Specifically, the "0" position of the watch is usually the normal use position and the winding position, the "1" position is the calendar / weekly adjustment position, and the "2" position is the watch time adjustment position. Therefore, the stem needs to be moved to adjust the gear position. When the stem needs to be disassembled, it is necessary to use external force to press the pull shaft to separate the pull piece and the stem. Previously, when the top shaft was applied, it was easy to cause the pull piece to be flipped over, causing the pull piece to also separate from the rotation point. Therefore, how to achieve easy disassembly and adjustment of the stem is a problem that we urgently need to solve. Utility Model Content

[0023] Example 1

[0024] Reference Figures 1 to 4 , which is the first embodiment of the utility model, proposes a watch shift-pull anti-flip device, including a splint 1 and a stem 2 movably arranged in the splint 1, the stem 2 having a first limit groove 3; also including a first shift member 4, one end of the first shift member 4 is hinged on the splint 1, the first shift member 4 swings along the hinge point for shifting, the first shift member 4 has a limit column 5, the first shift member 4 can be movably arranged on the splint 1 in the axial direction of the hinge point, the first shift member 4 moves to drive the limit column 5 to extend into or pull out of the first limit groove 3.

[0025] In this embodiment, in order to solve the above technical problems, a watch shift-pull-up and flip-over device is proposed, including a splint 1 and a stem 2 movably arranged on the splint 1, the stem 2 having a first limiting groove 3, and also including a first shift-pull member 4, one end of the first shift-pull member 4 is hinged on the splint 1, the first shift-pull member 4 swings along the hinge point for shifting, the first shift-pull member 4 has a limiting column 5, the first shift-pull member 4 can be movably arranged on the splint 1 in the axial direction of the hinge point, and the movement of the first shift-pull member 4 is used to drive the roller limiting column 5 to fall into or pull out of the first limiting groove 3. During operation, when the watch needs to be shifted, it is only necessary to pull the stem 2 to move the stem 2 in the splint 1. When the stem 2 moves, it will drive the first shift member 4 to rotate along the hinge point through the limit column 5, thereby making contact with other shift members to achieve shifting. When the watch needs to be repaired and the stem 2 needs to be pulled out, it is only necessary to push the first shift member 4 to move so as to disengage from the first limit slot 3, and the stem 2 can be pulled out, thereby removing the stem 2, and quickly removing the stem 2 to repair the watch.

[0026] Example 2

[0027] Compared with Example 1, it further includes a gear pulling top shaft 6, which is movably arranged on the splint 1, and the moving direction of the gear pulling top shaft 6 is parallel to the moving direction of the first gear pulling member 4. The movement of the gear pulling top shaft 6 is used to drive the first gear pulling member 4 to move, and the splint 1 has a second limiting groove 7. The gear pulling top shaft 6 has an annular portion 8, and the annular portion 8 moves with the gear pulling top shaft 6, and the annular portion 8 moves in the second limiting groove 7.

[0028] In this embodiment, the shift pull top shaft 6 is movably set on the splint 1. The movement of the shift pull top shaft 6 can move the first shift pull member 4, so that the limiting column 5 of the first shift pull member 4 is disengaged from the first limiting groove 3, so that the stem 2 can be pulled out, thereby disassembling the watch. In addition, a second limiting groove 7 is set on the splint 1, and a ring portion 8 is set on the shift pull top shaft 6. The ring portion 8 moves in the second limiting groove 7, which can limit the shift pull top shaft 6 and prevent the shift pull from affecting the first shift pull member 4 for too long a distance, thereby causing the first shift pull member 4 to flip over and make the first shift pull member 4 unable to recover.

[0029] Example 3

[0030] Compared with Examples 1-2, it further includes an elastic member 9, which is arranged on the splint 1, one end of the elastic member 9 contacts the splint 1, and the other end of the elastic member 9 contacts the first pulling member 4, and the elastic member 9 is used to provide the force for the limiting column 5 to extend into the first limiting groove 3.

[0031] In this embodiment, an elastic member 9 is also included. The elastic member 9 is arranged on the splint 1. One end of the elastic member 9 is in contact with the splint 1. The elastic member 9 can be compressed after the first shift member 4 is acted upon by the shift top shaft 6. When the handle shaft 2 is installed, the elastic member 9 can act on the first shift member 4 to reset. The elastic member 9 can be a spring or an elastic pad, etc.

[0032] Example 4

[0033] Compared with embodiments 1-3, further, the first limiting groove 3 is an annular groove, and the stem 2 is rotatably disposed in the splint 1. The second limiting groove 7 is an annular groove, and the annular portion 8 is movably disposed in the second limiting groove 7.

[0034] In this embodiment, the first limiting groove 3 is set as an annular groove, so that when the stem 2 is extended by the limiting column 5 of the first pull-shift member 4, the stem 2 can also rotate itself, thereby adjusting the value of the watch. The second limiting groove 7 is set as an annular groove, which allows the annular portion 8 of the pull-shift top shaft 6 to move in the second limiting groove 7 and rotate at the same time.

[0035] Example 5

[0036] Compared with embodiments 1-4, further, the splint 1 further includes a guide groove 10, and the guide groove 10 is arranged along the moving direction of the stem 2, and the stem 2 is moved and arranged in the guide groove 10.

[0037] In this embodiment, the splint 1 also includes a guide groove 10, and the stem 2 is movable and arranged in the guide groove 10. The guide groove 10 can prevent the stem 2 from shifting and can move in a linear direction, thereby making the disassembly and installation of the stem 2 more convenient.
