[0019] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] Please refer to Figure 1 , the present utility model discloses a crown stone setting anti-loosening structure 10 with stones not easily falling off and high installation stability. The crown stone setting anti-loosening structure 10 includes a crown body 100 for rotatably installing on the watch head and a stone 200 fixed on the crown body 100. The stone 200 can be one of ruby, emerald, sapphire, diamond, and zircon. On one side of the crown body 100 adjacent to the watch head, there is a plugging rod 110. The end of the plugging rod 110 is provided with a non-circular slot 120. The plugging rod 110 rotates through the side surface of the watch case 20 and is inserted into the inner cavity of the watch case 20. The movement driving shaft of the movement is inserted into the non-circular slot 120 at the end of the plugging rod 110, and the cross-section of the movement driving shaft is also a non-circular structure. Thus, when the crown body 100 rotates, the crown body 100 can drive the movement driving shaft to rotate via the plugging rod 110 to adjust the time of the watch. On the side surface of the crown body 100 facing away from the watch head, there is a groove 130. The bottom surface of the groove 130 is provided with an annular groove 140, and an anti-vibration rubber ring 300 is embedded in the annular groove 140. One side of the anti-vibration rubber ring 300 adjacent to the notch of the groove 130 protrudes from the bottom surface of the groove 130. The stone 200 is inlaid in the groove 130. The bottom surface of the stone 200 adheres to the bottom surface of the groove 130 and abuts against the anti-vibration rubber ring 300. The circumferential side part of the crown body 100 is bent towards the direction close to the center of the groove 130 to form a limiting part 150 for pressing the side surface or the top surface of the stone 200. In this embodiment, the top surface of the stone 200 refers to the surface of the stone 200 facing away from the watch head, and the bottom surface of the stone 200 refers to the surface of the stone facing the watch head. By making one side of the anti-vibration rubber ring 300 adjacent to the notch of the groove 130 protrude from the bottom surface of the groove 130, when the bottom surface of the stone 200 fits with the bottom surface of the groove 130, the anti-vibration rubber ring 300 is squeezed by the stone 200 and deforms, that is, the anti-vibration rubber ring 300 is always in a squeezed state to improve the reliability of the anti-vibration rubber ring 300 for limiting and damping the stone 200. Through the extrusion of the limiting part 150 on the crown body 100 on the side surface or the top surface of the stone 200, the limiting of the stone 200 in the depth direction of the groove 130 can be realized to prevent the stone 200 from coming out of the groove 130.

[0021] In one embodiment, the gemstone 200 has a hemispherical structure. The limiting part 150 is press-fitted against the side surface of the gemstone 200, and the inner side surface profile shape of the groove 130 is adapted to the side surface profile shape of the gemstone 200. In other words, the inner side surface of the groove 130 is a concave spherical surface. Thus, after the gemstone 200 is embedded in the groove 130, the concave spherical surface of the groove 130 is pressed against the outer side surface of the gemstone 200, applying an axial force to the gemstone 200 along the depth direction of the groove 130 and pointing towards the center of the watch head, and at the same time applying a radial force to the gemstone 200 along the width direction of the groove 130 and pointing towards the middle of the groove 130. Thus, under the combined restraint of the axial force and the radial force from the limiting part 150, the gemstone 200 is difficult to shake in the groove 130, and the gemstone 200 can be prevented from coming out of the groove 130. Please refer to Figure 2 , In another embodiment, the gemstone 200 has a columnar structure. The annular side part of the crown body 100 is bent at a position adjacent to the notch of the groove 130 to form a limiting part 150 that is press-fitted against the top surface of the gemstone 200. In this embodiment, the shape of the inner side surface of the groove 130 is adapted to the shape of the annular side surface of the gemstone 200 to limit the movement of the gemstone 200 along the width direction of the groove 130 and prevent the gemstone 200 from shaking in the groove 130. The vertical cross-section of the annular side part of the crown body 100 has an inverted L-shaped structure. That is to say, the plane where the limiting part 150 is located is perpendicular to the depth direction of the groove 130. That is, the limiting part 150 is perpendicular to the inner side surface of the groove 130. Thus, by pressing the top surface of the gemstone 200 with the limiting part 150, the gemstone 200 can be prevented from coming out of the groove 130. Further, the gemstone 200 has a cylindrical structure or a multi-prismatic structure. Preferably, the cross-section of the gemstone 200 is a polygon, and the number of sides of the polygon is an integer greater than or equal to three. That is to say, the gemstone 200 can have a structure such as a quadrangular prism, or a pentagonal prism, or a hexagonal prism, or an octagonal prism, or a decagonal prism, or a dodecagonal prism, etc.

[0022] In one embodiment, the annular side part of the crown body 100 has a tubular structure to protect the side surface of the gemstone 200. In another embodiment, the annular side part of the crown body 100 includes a plurality of clamping claws distributed at intervals along an annular path. That is to say, in this embodiment, the crown body 100 has a hollow design, and the plurality of clamping claws are all bent to form limiting parts 150 to jointly clamp the gemstone 200 and achieve the positioning of the gemstone 200. In addition, the outer ring surface of the crown body 100 is also provided with anti-slip stripes to prevent slipping when turning the crown body 100 and reduce the difficulty of adjusting the time of the watch.

[0023] It should be noted that the shockproof rubber ring 300 is installed in the annular groove 140 in a variety of replaceable ways. Specifically, in one embodiment, the shockproof rubber ring 300 is embedded in the annular groove 140 and bonded to the inner surface of the annular groove 140 by glue. In another embodiment, the width of the annular groove 140 is slightly smaller than the width of the shockproof rubber ring 300. In this way, the shockproof rubber ring 300 can be inserted into the annular groove 140 by means of extrusion deformation to achieve the positioning of the shockproof rubber ring 300. Further, the shockproof rubber ring 300 is made of rubber or silica gel. For example, the shockproof rubber ring 300 can be made of natural rubber, or silicone rubber, or ethylene propylene rubber, or nitrile rubber, or fluorinated rubber to ensure the shock absorption and limiting effect of the shockproof rubber ring 300 on the inlaid stone 200.

[0024] In one embodiment, the cross-section of the shockproof rubber ring 300 is circular or elliptical or rectangular, and the cross-sectional areas of all parts of the shockproof rubber ring 300 are the same. The inner contour shape of the annular groove 140 is adapted to the outer contour shape of the shockproof rubber ring 300. That is to say, the shockproof rubber ring 300 has the same width or diameter everywhere. Preferably, please combine Figure 1 with Figure 3 , the cross-section of the shockproof rubber ring 300 is elliptical. Please refer to Figure 4, in another embodiment, the shock-proof rubber ring 300 includes a plurality of elastic shock-absorbing blocks 310 distributed at intervals along an annular path. Two adjacent elastic shock-absorbing blocks 310 are connected by an arc-shaped connecting strip 320. The cross-sectional area of the arc-shaped connecting strip 320 is smaller than that of the elastic shock-absorbing block 310. The dimension of the elastic shock-absorbing block 310 along the depth direction of the groove 130 is greater than the dimension of the arc-shaped connecting strip 320 along the depth direction of the groove 130, and at least the elastic shock-absorbing block 310 protrudes from the bottom surface of the groove 130. That is to say, the shock-proof rubber ring 300 realizes multi-point contact with the inlaid stone 200 through a plurality of elastic shock-absorbing blocks 310. While ensuring that the shock-proof rubber ring 300 presses the inlaid stone 200 tightly, when the inlaid stone 200 is inserted into the groove 130, the air in the groove 130 can be discharged through the gap between the elastic shock-absorbing block 310 and the arc-shaped connecting strip 320, avoiding the interference of the air column in the groove 130 on the installation of the inlaid stone 200, so as to reduce the installation difficulty of the inlaid stone 200. In addition, according to different production processes, the elastic shock-absorbing block 310 can be spherical, ellipsoidal or cubic in structure. In this embodiment, the bottom surface of the annular groove 140 can be a plane. At this time, the bottom surface of the arc-shaped connecting strip 320 is flush with the bottom surface of the elastic shock-absorbing block 310. In other embodiments, the arc-shaped connecting strip 320 is connected to the middle of the side surface of the elastic shock-absorbing block 310. That is to say, both sides of the elastic shock-absorbing block 310 protrude correspondingly from the top surface and the bottom surface of the arc-shaped connecting strip 320. Correspondingly, limiting grooves corresponding to each elastic shock-absorbing block 310 are arranged at intervals in the annular groove 140, and the notch position of the limiting groove is flush with the bottom surface of the annular groove 140. In this way, through the limiting groove, the elastic shock-absorbing block 310 can be limited to prevent the shock-proof rubber ring 300 from moving in the annular groove 140, and improve the reliability of the shock-proof rubber ring 300 in limiting the inlaid stone 200.

[0025] In addition, the present utility model also discloses a watch, which includes the above-mentioned crown inlaid stone anti-loosening structure 10. The watch further includes a watch case, a movement housed in the inner cavity of the watch case, a back cover covering the back of the watch case, a dial housed in the inner cavity of the watch case and located on the side of the movement facing away from the back cover, a watch glass covering the front surface of the watch case, and a watch band connected to the outer side wall of the watch case. Among them, a through hole is provided on the side surface of the watch case, and the insertion rod 110 of the crown body 100 passes through the through hole and is connected to the driving shaft of the movement, so as to adjust the time of the watch when the crown body 100 is rotated. In addition, it should be emphasized that the watch in this embodiment can be either a mechanical watch or a quartz watch, which is specifically determined according to the type of the movement, and will not be elaborated here.

[0026] The above-mentioned crown stone anti-loosening structure 10 and the watch, by opening an annular groove 140 in the groove 130 of the crown body 100 and installing a shock-proof rubber ring 300 in the annular groove 140. On the one hand, the shock-proof rubber ring 300 and the limiting part 150 on the crown body 100 jointly press against the inlaid stone 200 to prevent the inlaid stone 200 from loosening. On the other hand, the shock-proof rubber ring 300 can also achieve shock absorption and buffering for the inlaid stone 200 to avoid loosening or falling off of the inlaid stone 200 under external impact. In addition, the shock-proof rubber ring 300 is also used to wrap the bottom of the inlaid stone 200 to reduce the wear of the inlaid stone 200 and avoid the problem that the inlaid stone 200 becomes smaller due to wear during long-term use and then falls off from the groove 130, improving the stability of the installation of the inlaid stone 200 on the crown body 100 and preventing the inlaid stone 200 from falling off.

[0027] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0028] The above-mentioned embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
