[0035] See also Figures 1 to 10 According to an embodiment of the utility model, a waterproof structure of a watch comprises a watch case 1 and a watch mirror 2, a watch dial 3, a movement 4 and a waterproof back cover 5 which are sequentially installed in the watch case 1. An opening is arranged on one side of the watch case 1, and a waterproof structure is arranged at the opening of the watch case 1. The waterproof structure comprises a bar head 6 and a bar tube 7. The outer surface of the bar head 6 is provided with an anti-slip embossing 65, a stepped groove 61 is arranged in the bar head 6, a tube column 62 is arranged at the bottom of the stepped groove 61, the tube column 62 is inserted into one end of the bar tube 7, and a bar rod 8 is inserted into the other end of the bar tube 7. A tube hole 621 is provided in the middle of the tube column 62, and a bar 63 is passed through the tube hole 621. A compression spring 64 is provided between one end of the bar 63 and the bottom of the stepped groove 61. The other end of the bar 63 is meshed with one end of the bar rod 8. The other end of the bar rod 8 extends from the bar tube 7 and is connected to the gear 9. The bar tube 7 is provided with an inner card platform 71, which is used to limit the bar rod 8 so that the bar rod 8 cannot be pulled out of the bar tube 7. At least one sealing component is provided between the bar tube 7 and the tube column 62, and an annular groove for installing the sealing component is provided on the inner wall of the bar tube 7.
[0036] The sealing component includes a first sealing gasket 10 and a second sealing gasket 11, and the annular groove includes a first annular groove 12 and a second annular groove 13. The first annular groove 12 and the second annular groove 13 are sequentially arranged on the inner wall of the bar tube 7. The first sealing gasket 10 is installed in the first annular groove 12, and the part of the first sealing gasket 10 located outside the first annular groove 12 is tightly pressed against the outer side of the tube column 62; the second sealing gasket 11 is installed in the second annular groove 13, and the part of the second sealing gasket 11 located outside the second annular groove 13 is tightly pressed against the outer side of the tube column 62.

The gear is locked to the bar head, the bar is twisted out of the bar tube, and the teeth on the bar rod are engaged. At this time, the gear connects the bar rod and the bar to become an integral part. When the bar rotates, it can drive the gear to rotate, thereby engaging the gear of the inner ring on the case to rotate. When this function is not executed, the bar is rotated to lock into the bar tube and return to the original state, so that the entire watch can reach 20-30 degrees waterproof.
[0041] like Figure 2 As shown, at this time, after the rotation of the bar is opened, the bar is rotated, and the bar drives the rotating teeth to engage with the teeth of the inner ring, so that the inner ring rotates.
[0042] The utility model has the advantages that the watch has strong waterproof performance, and even when the watch is in a rotating working state, it has strong waterproof ability, which reduces the occurrence of accidental water ingress into the watch, prolongs the service life, and reduces the maintenance cost.
[0043] The utility model also provides a waterproof watch, comprising the waterproof structure of the watch.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
