Description

Technical Field

[0001] The utility model relates to the technical field of watch crowns, and more specifically, to a rotating crown for a wrist-worn device. Background Art

[0002] A watch crown, usually also known as the "stem" or "crown", is a very important component of a watch. It is located on one side of the watch case and is mainly used for winding the mainspring of a manually-wound mechanical watch, as well as adjusting time, date, and other complex functions, such as a chronograph or world time. The correct use and maintenance of the crown are crucial for the long-term operation of the watch.

[0003] In the existing crown, time is adjusted by rotating it clockwise or counterclockwise. In a manually-wound mechanical watch, rotating the crown can wind up the mainspring of the movement. The crown head is the externally visible part of the crown, usually made of metal and may be plated or decorated for easy grasping and rotation. The crown shaft is the part connecting the crown head and the movement. It passes through the side of the watch case and transmits the rotational movement to the gear system inside the movement.

[0004] In the actual use of the prior art, due to the relatively complex internal structure of the watch, when it is necessary to remove the crown for maintenance or replacement, the operation is rather cumbersome, and it is easy to damage the crown or the movement due to improper operation. Therefore, a rotating crown for a wrist-worn device is proposed. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the utility model provides a rotating crown for a wrist-worn device. By manually pushing the push block outwards, the spring is compressed through the moving plate, driving the insertion rod to move outwards and away from the inner cavity of the mounting sleeve. At this time, the mounting sleeve loses its fixed limit and can be removed from the housing, thus easily removing the crown from the housing. Compared with the traditional disassembly method, it is simpler, more convenient, and will not damage other parts.

[0029] Embodiment 1

[0030] Reference Figures 1-5 As the first embodiment of the present utility model, this embodiment provides a rotating crown for a wrist - worn device, including a housing 1. A disassembly component 2 is arranged in the inner cavity of the housing 1, which includes a mounting sleeve 207 movably connected in the inner cavity of the housing 1. A crown shaft 202 is movably connected in the inner cavity of the mounting sleeve 207. One end of the crown shaft 202 is fixedly connected with a crown head 201. A plug rod 203 is slidably connected in the inner cavity of the housing 1. One end of the plug rod 203 is fixedly connected with a moving plate 204, and one end of the moving plate 204 is fixedly connected with a spring 206.

[0031] Specifically, a plurality of arc - shaped protrusions are uniformly arranged on the outer surface of the crown head 201, and the crown head 201 and the arc - shaped protrusions are integrally formed. Two jacks are symmetrically opened on the outer surface of the mounting sleeve 207, and the plug rod 203 moves in the jacks. One end of the spring 206 is fixedly connected with the inner wall of the housing 1, the moving plate 204 moves in the inner cavity of the housing 1, and a pushing block 205 is fixedly connected to one side of the moving plate 204.

[0032] Furthermore, when holding the crown head 201 and driving the crown shaft 202 to rotate, there is a small gear at the end of the crown shaft 202 that engages with the internal gears of the movement. When the crown is rotated, this small gear drives the corresponding gears inside the movement, thereby realizing functions such as winding or adjusting time. By manually pushing the pushing block 205 outwards, the spring 206 is compressed through the moving plate 204, driving the plug rod 203 to move outwards and leave the inner cavity of the mounting sleeve 207. At this time, the mounting sleeve 207 loses its fixed limit and can be removed from the housing 1, so that the crown can be easily removed from the housing 1. Compared with the traditional disassembly method, it is more convenient and will not damage other parts. The diameter of the small gear provided at one end of the crown shaft 202 is designed to be smaller than the diameter of the mounting sleeve 207, which is convenient for taking out the whole from the housing 1.

[0033] Embodiment 2

[0034] Reference Figures 1-5 As the second embodiment of the present utility model, this embodiment is based on the previous embodiment. An adjusting component 3 is arranged in the inner cavity of the disassembly component 2, which includes a plurality of adjusting rods 302 movably connected in the inner cavity of the crown shaft 202, and one end of each adjusting rod 302 is fixedly connected with a connecting spring 303.

[0035] Specifically, a plurality of adjusting grooves 301 are uniformly opened in the inner cavity of the mounting sleeve 207, the adjusting rods 302 rotate in the adjusting grooves 301. One end of the adjusting rod 302 is semi - circular, and the other end of the adjusting rod 302 is fixedly connected with a connecting spring 303, and one end of the connecting spring 303 is fixedly connected with the inner wall of the crown shaft 202.

[0036] Furthermore, the crown shaft 202 moves outward, squeezing the adjusting lever 302 and the connecting spring 303. When the outward movement of the crown shaft 202 drives the adjusting lever 302 into the interior of the adjusting groove 301 at another position, the crown is pulled out to the first gear position. At this time, the crown can be rotated to adjust the pointer to the correct time position. The multiple adjusting grooves 301 on the crown shaft 202 represent different gears, and different pointers can be adjusted for each gear. The operator can rotate it flexibly and adjust it according to the needs.

[0037] Working principle: During the use of the device, the operator drives the rotation of the crown shaft 202 by holding the crown head 201. When in use, by pulling the crown head 201 outward, the crown shaft 202 is driven to move, and the adjusting lever 302 and the connecting spring 303 are squeezed. When the outward movement of the crown shaft 202 drives the adjusting lever 302 into the interior of the adjusting groove 301 at another position, the crown is pulled out to the first gear position. At this time, the crown can be rotated to adjust the pointer to the correct time position. The multiple adjusting grooves 301 on the crown shaft 202 represent different gears and different pointers can be adjusted. The operator can rotate it flexibly and adjust it according to the needs. When the crown needs to be disassembled for repair or replacement, manually push the pushing block 205 outward at this time, squeeze the spring 206 through the moving plate 204, and drive the insertion rod 203 to move outward and leave the inner cavity of the mounting sleeve 207. At this time, the mounting sleeve 207 loses its fixed limit and can be removed from the housing 1, so that the crown can be easily removed from the housing 1, which is more convenient than the traditional disassembly method and will not damage other parts.

[0038] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
