[0024] The following will be combined with the accompanying 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] The embodiment of the present application discloses a watch case that prevents the bezel from rotating accidentally. Figures 1 to 3The cam 2 is provided with a plurality of cams, and the ... 1 is arranged in the form of equal intervals; a locking rod 4 is provided on the circumferential side of the main body 1, and one end of the locking rod 4 is rotatably connected to the main body 1 so that the other end of the locking rod 4 can rotate along this position. In this embodiment, one end of the locking rod 4 is rotatably connected to the main body 1 through a rotating shaft, and a pin 41 is provided at the end of the locking rod 4 away from the rotation connection with the main body 1. The pin 41 is integrally connected with the locking rod 4, and the pin 41 is used to be inserted into the limiting groove 31 of the limiting ring 3. Therefore, when the watch needs to be used for timing, the bezel 2 is first rotated so that the mark is in a predetermined position, and then the locking rod 4 is rotated so that the pin 41 on the locking rod 4 is inserted into the limiting groove 31. At this time, the side wall of the limiting groove 31 and the pin 41 of the locking rod 4 cooperate to limit the rotation of the bezel 2, so the bezel 2 can be prevented from changing the mark position due to accidental touch, thereby ensuring the accuracy of the watch timing as much as possible.

The crown 11 is connected to the pointer of the watch to realize controlling the position of the pointer by rotating the crown 11. In order to save the production cost of the watch and make the appearance of the watch more coordinated and beautiful, the middle part of the locking rod 4, that is, between the pin 41 and the rotating shaft is set to be bent. At the same time, when the pin 41 on the locking rod 4 is inserted into the limiting groove 31, the pin 41 and the rotating shaft are respectively on both sides of the crown 11, and the crown 11 is on the inner side of the curved needle of the middle bent part of the locking rod 4. At this time, the locking rod 4 can also protect the crown 11, which can avoid the rotation of the crown 11 due to accidental touch as much as possible, thereby ensuring the accuracy of the watch time, and limiting the bezel 2 and the crown 11 through a locking rod 4, saving costs and improving the ornamental effect.
[0027] Reference Figure 2 and Figure 3, in this embodiment, in order to reduce the thickness of the watch, a rotating ring groove 12 is provided on the upper side of the body 1. The cross-section of the rotating ring groove 12 is annular when viewed from the notch direction, and the rotating ring groove 12 is coaxial with the body 1. The limit ring 3 is provided on a side of the bezel 2 close to the bottom of the rotating ring groove 12, that is, the rotating ring groove 12 is used for placing the limit ring 3. At the same time, a limiting hole 13 is provided on the outer side wall of the rotating ring groove 12. In this embodiment, the limiting hole 13 is connected to the notch of the rotating ring groove 12. The limiting hole 13 is used for penetration, that is, when the locking rod 4 rotates to make the pin 41 rotate synchronously, the pin 41 will penetrate through the limiting hole 13 and be inserted into the predetermined limiting groove 31, so that the limiting ring 3 can be hidden in the rotating ring groove 12 to reduce the overall thickness of the watch.
[0028] Reference Figure 2 and Figure 3 In order to make the latch 41 firmly inserted in the limiting groove 31, a stabilizing rod 14 is provided on the body 1. The stabilizing rod 14 is cylindrical in shape as a whole. The stabilizing rod 14 is provided on one side close to the latch 41, and the stabilizing rod 14 and the rotating shaft are respectively provided on both sides of the crown 11.

In this embodiment, a stabilizing groove 42 is provided on the inner side of the bend of the locking rod 4. The stabilizing groove 42 is provided on the inner side of the bend of the locking rod 4. 2 is in the form of a through groove, and the shape of the stabilizing groove 42 is adapted to the stabilizing rod 14. When the stabilizing rod 14 is in the stabilizing groove 42, the axis of the stabilizing rod 14 is parallel to the extension direction of the stabilizing groove 42, and the outer side wall of the stabilizing rod 14 is tightly fitted and abutted against the side wall of the stabilizing groove 42 to achieve stable installation of the locking rod 4. In other embodiments, the arc length of the stabilizing groove 42 can exceed 180° when viewed from the opening direction, and the notch of the stabilizing groove 42 can be blocked to further improve the stability of the locking rod 4.
[0029] The implementation principle of a watch case that prevents the bezel from rotating accidentally in an embodiment of the present application is as follows: when the watch needs to be used for timing, the bezel 2 is first rotated to a predetermined position, and then the locking rod 4 is rotated so that the pin 41 of the locking rod 4 passes through the limiting hole 13 and is inserted into the limiting groove 31. At this time, the stabilizing rod 14 on the main body 1 will be tightly fitted in the stabilizing groove 42. The bezel 2 is limited by the pin 41 and the limiting groove 31, which can avoid the bezel 2 from rotating due to accidental touch, thereby improving the accuracy of the watch timing.
