Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical watch movements, and more particularly to a front valve structure of a watch movement. Background Art
[0002] Mechanical watches can generally be divided into the following two types: manual-winding and automatic-winding watches. Manual-winding mechanical watches rely on manually twisting the mainspring for power, and the thickness of the movement is thinner than that of general automatic-winding watches. The front valve structure in the mechanical watch movement is used to adjust the structure of the watch. However, since the rotating rod needs to be pulled out and pushed in, it is difficult to control its pulling out or pushing in position during operation. After long-term use, its connection stability will be reduced. In addition, the structure is cumbersome and complicated, and the production cost is high.
[0003] For example, announcement No. CN219105346U discloses a front valve structure of an ultra-thin mechanical watch movement, including a rotating rod, a guard rod is fixedly inserted and connected to the left outer surface of the rotating rod, a connecting column is fixedly connected to the left end of the guard rod, a rotating head is fixedly connected to the left outer surface of the rotating rod, a limiting block is fixedly inserted and connected to the middle outer surface of the rotating rod, a vertical wheel mechanism is fixedly inserted and connected to the right outer surface of the limiting column, a fixed column is fixedly inserted and connected to the right outer surface of the rotating rod, and a clutch mechanism is movably inserted and connected to the right outer surface of the fixed column.
[0004] It can be seen from the above-mentioned public scheme that the second tooth head and the first tooth head set at the docking position of the vertical wheel mechanism and the clutch mechanism will increase the production difficulty of the vertical wheel mechanism and the clutch mechanism, thereby increasing the production cost, and the axial position of the rotating rod cannot be accurately fixed during the pulling out and pushing process. After long-term wear, it will reduce the connection stability between the front valve structure and other structures. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example 1
[0026] See also Figure 1-5, a front valve structure of a watch movement, the installation method of the front valve assembly and the composition structure and method with other parts of the watch are all existing technologies and are well known to those skilled in the art. It includes a rotating head 1, which is convenient for the user to rotate manually. One end of the rotating head 1 is fixedly connected to a connecting column 21, and the other end of the connecting column 21 is fixedly connected to a rotating rod 2. One end of the rotating rod 2 is fixedly connected to a limiting member 22, and one end of the limiting member 22 is fixedly connected to a vertical wheel member 3. The surface of the vertical wheel member 3 is fixedly sleeved with an insertion rod 31. After the insertion rod 31 is plugged into the clutch member 4, the clutch member 4 can be driven to rotate by the rotating rod 2. The surface of the insertion rod 31 is fixedly sleeved with a limiting block 22, and one end of the insertion rod 31 is fixedly sleeved with a telescopic arm 5. The retractable arm 5 can automatically control the rotating rod 2 to pull out and push the watch. The other end of the telescopic arm 5 is fixedly sleeved with a clutch 4. One end of the clutch 4 is provided with a limit groove 41, and the bottom of the limit groove 41 is provided with a slot 42. The bottom of the slot 42 is provided with a mounting groove 43. One end of the telescopic arm 5 is in the mounting groove 43. The other end of the rotating head 1 is provided with a countersunk groove 11. The bottom of the countersunk groove 11 is provided with a screw hole 15, which is convenient for fixing the switch 14 by screws when installing the switch 14. One end of the countersunk groove 11 is sleeved with a cover plate 13, which is made of environmentally friendly rubber material. The switch 14 can be directly pressed by pressing the cover plate 13. The inner wall of the countersunk groove 11 is fixedly installed with the switch 14, and the switch 14 belongs to the existing technology.
[0027] One end of the connecting column 21 is provided with a through hole 12 connected to the countersunk groove 11, and one end of the limit piece 22 and the insertion rod 31 are provided with holes that are connected to each other. One end of the hole is connected to the through hole 12. The countersunk groove 11 facilitates the installation and disassembly of the switch 14 and can prevent the switch 14 from being accidentally pressed. The telescopic arm 5 is an electric telescopic column. The telescopic arm 5 and the switch 14 are electrically connected through a wire. The surface of the wire is in contact with the through hole 12 and the inner wall of the hole. The through hole 12 and the hole facilitate the arrangement of the wire, and the extension and retraction of the telescopic arm 5 can be controlled by the switch 14.
[0028] The surface of the connecting column 21 is slidably sleeved with a sealed bearing 6. The shape of the central axis hole of the sealed bearing 6 is polygonal, and the cross-sectional shape of the connecting column 21 is also polygonal. The outer ring of the sealed bearing 6 is fixed to the inner wall of the watch case, ensuring that the connection with the rotating rod 2 will not be directly worn. The shapes of the insertion rod 31 and the limit block 32 are both polygonal, and the shapes of the limit groove 41 and the slot 42 are also polygonal. The depth of the slot 42 is greater than the length of the insertion rod 31, so that after the insertion rod 31 and the slot 42 are plugged in, the rotating rod 2 can drive the clutch 4 to rotate.
[0029] When the front valve structure of the watch movement needs to pull out the rotating rod 2, the cover plate 13 can be manually pressed, causing the cover plate 13 to deform and squeeze the switch 14. At this time, the telescopic arm 5 starts to work, so that one end of it extends, thereby driving the insertion rod 31 to move out of the slot 42, so that the rotating rod 2 is pulled out. When the rotating rod 2 is rotated, the clutch 4 will not rotate synchronously. When the rotating rod 2 needs to be advanced, the switch 14 is pressed in the above manner, causing the telescopic arm 5 to retract, driving the insertion rod 31 and the limit block 32 to be inserted into the slot 42 and the limit groove 41 respectively. When the rotating rod 2 is rotated, the clutch 4 can be driven to rotate synchronously. The provision of the telescopic arm 5, the insertion rod 31 and the slot 42 can quickly and accurately control the advancement and extraction position of the rotating rod 2, greatly improving the connection stability of the front valve structure. In addition, the provision of the polygonal insertion rod 31, the limit block 32, the limit groove 41 and the slot 42 can greatly reduce the production difficulty of the clutch 4 and the vertical wheel part 3, thereby effectively reducing the production cost.
[0030] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
