Description

Technical Field

[0001] The utility model relates to the technical field of watches, in particular to a watch bezel rotating structure capable of non-destructive disassembly and assembly and a watch. Background Art

[0002] For watches that require timing, a rotatable bezel (i.e., a rotating structure) is usually configured on the case, and the bezel is driven to rotate by the internal components of the watch, so that the watch can be used for timing. At present, there are mainly two types of connection structures between the bezel and the case of watches on the market. One is a ring-mouth embedded structure connected by a spring wire or an extruded rubber ring, and the other is a screw connection structure. The former does not affect the appearance of the bezel, but is difficult to disassemble. After disassembly, the case ring is easily deformed, and the spring wire and rubber ring are easily damaged, making some parts unable to be reused, and requiring high technical skills from maintenance and after-sales personnel; the latter will destroy the appearance of the case ring (the connection structure between the case and the bezel), and as the rotation time of the bezel increases, the screw connection structure is easy to loosen, and its service life is short, making the stability and reliability of the bezel installation insufficient.

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0029] The utility model discloses a watch bezel rotation structure 10 with non-destructive disassembly and assembly, which can meet the needs of bezel rotation while shielding the bezel connection part, thus reducing the impact on the appearance of the case bezel. The bezel is easy to disassemble and assemble, and can realize non-destructive disassembly and replacement of the bezel. Figure 1-8The watch bezel rotating structure of this embodiment includes a watch case 100, an outer ring 200, an inner ring 300 and a decorative ring 400. The watch case 100 is provided with a cavity 110 that runs through the main surface of the watch case 100 and the back surface of the watch case 100. The cavity 110 is used to store the watch movement. The main surface of the watch case 100 refers to the side of the watch case 100 that faces the user when the watch is worn; the back surface of the watch case 100 refers to the side of the watch case 100 that fits the user's body when the watch is worn. The main surface of the watch case 100 is provided with a bezel groove 120 surrounding the cavity 110. The bottom surface of the bezel groove 120 is provided with a plurality of first limiting grooves 130. The first limiting groove 130 is provided with a first limiting member 140 and a first spring 150 that is fixedly connected to the first limiting member 140 and elastically connected to the inner surface of the first limiting groove 130. In this embodiment, the bottom end of the first stopper 140 is spaced from the bottom surface of the first stopper groove 130 by a preset distance, and the preset distance is greater than 0, that is, the first stopper 140 is elastically installed in the first stopper groove 130 through the first spring 150. The first stopper 140 has an abutment portion located above the first spring 150, that is, no matter what assembly method is adopted between the first stopper 140 and the first spring 150, at least a portion of the first stopper 140 is located at the upper end of the first spring 150, so that the top end of the first stopper 140 can provide an abutment portion abutting against the lower surface of the outer ring 200. A first guide bevel 160 and an annular V-shaped groove 170 located below the first guide bevel 160 and surrounding the cavity 110 are provided at the upper end of the inner wall of the bezel groove 120 adjacent to the cavity 110. That is to say, a first guide bevel 160 is formed at the edge of the groove of the bezel groove 120 adjacent to the cavity 110 so that the width of the bezel groove 120 at the groove is greater than the inner width of the bezel groove 120. The inner surface of the annular V-shaped groove 170 is an inclined surface or an arc surface. In this embodiment, the annular V-shaped groove 170 is used to provide a limiting fitting portion between the inner ring 300 and the watch case 100.

[0030] The outer ring 200 is embedded in the bezel groove 120, the lower surface of the outer ring 200 abuts against the abutment portion of the first stopper 140, the inner ring surface of the outer ring 200 is raised to form an annular step 210 extending along the circumferential direction of the outer ring 200 and at least one positioning protrusion 220 located above the annular step 210, and the upper edge of the annular step 210 is provided with a second guiding inclined surface 230. The inner ring 300 is embedded in the bezel groove 120, and the outer ring surface of the inner ring 300 abuts against the inner ring surface of the outer ring 200, and the inner ring surface of the inner ring 300 abuts against the inner wall of the bezel groove 120 adjacent to the cavity 110. It can be understood that when the outer ring 200 is inserted into the bezel groove 120, the outer ring surface of the outer ring 200 abuts against the inner surface of the bezel groove 120 on the side away from the cavity 110, and a groove body for the inner ring 300 to be inserted is formed between the inner ring surface of the outer ring 200 and the inner surface of the bezel groove 120 on the side adjacent to the cavity 110. The inner ring 300 and the outer ring 200 of this embodiment together constitute a rotatable bezel of the watch bezel rotating structure, which is used to rotate under the drive of the internal device of the cavity 110 to provide the timing function of the watch. The top of the inner ring 300 protrudes in the direction away from the cavity 110 to form a limiting boss 310 abutting against the side of the annular step 210 facing the notch of the bezel groove 120, that is, the lower edge of the limiting boss 310 forms a step, and the width of the top of the inner ring 300 is greater than the width of the bottom of the inner ring 300. The outer ring 200 is limited by the contact between the limiting boss 310 and the annular step 210 on the outer ring 200 to prevent the outer ring 200 from leaving the bezel groove 120 under the push of the first spring 150 and the first limiting member 140, and when subjected to external force, the outer ring 200 can move downward synchronously with the inner ring 300, and the inner ring 300 can move upward synchronously with the outer ring 200 to meet the disassembly and assembly requirements of the inner ring 300.

[0031] At least one positioning groove 320 is provided on the side of the limiting boss 310 facing away from the cavity 110, and the positioning groove 320 is matched with the positioning convex part 220. The relative rotation between the inner ring 300 and the outer ring 200 can be limited by the matching of the positioning convex part 220 and the positioning groove 320, so that the inner ring 300 and the outer ring 200 rotate synchronously for timing, avoiding the separation of the inner ring 300 and the outer ring 200 caused by the user's misoperation, and improving the stability and reliability of the watch bezel rotation structure. Preferably, the positioning groove 320 is an arc groove, and the outer contour shape of the positioning convex part 220 is adapted to the inner contour shape of the positioning groove 320. The inner ring 300 is also provided with a plurality of pin holes 330 penetrating the inner ring surface and the outer ring surface of the inner ring 300. The pin holes 330 extend in the radial direction of the inner ring 300, that is, the length of the pin holes 330 is the width (or thickness) of the portion of the inner ring 300 where the pin holes 330 are located. A positioning pin 340 is inserted into each pin hole 330. The diameter of the positioning pin 340 is smaller than the inner diameter of the pin hole 330 to ensure that the positioning pin 340 slides smoothly in the pin hole 330. The length of the pin hole 330 is smaller than the length of the positioning pin 340, and the length of the positioning pin 340 is smaller than the width of the top of the inner ring 300. One end of the positioning pin 340 is embedded in the annular V-shaped groove 170, and the other end of the positioning pin 340 abuts against a surface of the annular step 210 adjacent to the cavity 110. That is to say, when the positioning pin 340 is placed in the pin hole 330, at least one end of the positioning pin 340 extends out of the pin hole 330, so that when the inner ring 300 is installed, the positioning pin 340 can cooperate with the inner wall of the annular V-shaped groove 170 and the annular step 210 to limit the inner ring 300. The decorative ring 400 is located above the inner ring 300, and the lower surface of the decorative ring 400 is fixedly connected to the upper surface of the inner ring 300. It should be noted that in this embodiment, the matching mode of the positioning pin 340 with the annular V-shaped groove 170 and the annular step 210 is the matching mode after the inner ring 300 is assembled. At different stages of the disassembly and assembly of the watch bezel rotating structure, the position of the positioning pin 340 is different. In combination with the disassembly and assembly process of the watch bezel rotating structure, the matching relationship between the positioning pin 340 and the corresponding parts on the inner ring 300, the outer ring 200 and the watch case 100 at different stages is explained below.

[0032] During the assembly process of the watch bezel rotating structure, the first spring 150 and the first stopper 140 are first sequentially installed into the first stopper groove 130 of the watch case 100, and then the outer ring 200 is placed into the bezel groove 120 of the watch case 100. The positioning pin 340 is placed into the pin hole 330 of the inner ring 300, and the inner ring 300 with the positioning pin 340 is placed into the groove body formed between the side of the bezel groove 120 adjacent to the cavity 110 and the inner ring surface of the outer ring 200, and the inner ring 300 is pressed so that the inner ring 300 gradually moves downward in the groove body. When the end of the locating pin 340 adjacent to the cavity 110 contacts the first guiding bevel 160 of the watch case 100, as the inner ring 300 moves downward, the first guiding bevel 160 will push the locating pin 340, causing the locating pin 340 to move in the pin hole 330 in the direction away from the cavity 110; when the inner ring 300 continues to move downward until the end of the locating pin 340 away from the cavity 110 abuts against the second guiding bevel 230 on the annular step 210, the second guiding bevel 230 squeezes the locating pin 340 in the direction close to the cavity 110. Since the locating pin 340 has not reached the position of the annular V-shaped groove 170 at this time, there is no space in the groove body for the locating pin 340 to move in the direction close to the cavity 110. The locating pin 340 will press the outer ring 200 downward, causing the first spring 150 to be compressed and the first limit member 140 to move downward. At this time, the inner ring 300 and the outer ring 200 move downward synchronously. When the inner ring 300 and the outer ring 200 move down synchronously to the position where the positioning pin 340 reaches the annular V-shaped groove 170, the second guide inclined surface 230 pushes the positioning pin 340, so that the positioning pin 340 moves in the pin hole 330 in the direction close to the cavity 110 until the positioning pin 340 extends into the annular V-shaped groove 170. At this time, the pressure on the inner ring 300 is canceled, and the outer ring 200 will rise under the joint push of the first spring 150 and the first stopper 140 until the side of the annular step 210 adjacent to the cavity 110 abuts against the positioning pin 340. In this way, the positioning pin 340 is positioned by the annular step 210 and the annular V-shaped groove 170, thereby realizing the connection between the inner ring 300 and the outer ring 200 and the positioning of the inner ring 300 and the outer ring 200 on the watch case 100, and completing the assembly of the rotating structure of the watch bezel.

[0033] When the rotating structure of the watch bezel is disassembled, the outer ring 200 is first pressed to separate the positioning protrusion 220 on the outer ring 200 from the positioning groove 320 on the inner ring 300, and the outer ring 200 is rotated to separate the positioning protrusion 220 from the positioning groove 320. During the process of pressing the outer ring 200 downward, the first spring 150 is compressed and the first stopper 140 moves downward. At this time, the pressing force acting on the outer ring 200 is cancelled, and the outer ring 200 rises under the push of the first spring 150 and the first stopper 140 until the positioning protrusion 220 on the outer ring 200 abuts against the lower edge of the stopper boss 310 on the inner ring 300, and the outer ring 200 stops rising. At this time, an outward movement space for the positioning pin 340 to move back to the cavity 110 is formed between the inner ring 300 and the outer ring 200. Then, grasp the outer ring 200 and pull it upwards. The outer ring 200 will drive the inner ring 300 to move upward synchronously. Due to the effect of the inner wall inclined surface of the annular V-shaped groove 170, during this process, the inner wall of the annular V-shaped groove 170 will push the positioning pin 340 to move in the direction away from the cavity 110 until the positioning pin 340 is completely separated from the annular V-shaped groove 170, and the inner ring 300 and the outer ring 200 are separated from the watch case 100, thus completing the disassembly of the watch bezel rotating structure.

[0034] When the above watch bezel rotating structure is applied, the assembly process of the inner ring 300 and the outer ring 200 does not require complex processes such as pressing hard and tightening screws. It relies on its unique structure with ingenious design, and the inner ring 300 and the outer ring 200 can be assembled in sequence. After the assembly is completed, the positioning pin 340 inside it not only plays a role in preventing falling off, but also plays a role similar to the bearing ball, making the whole structure stable up and down and rotating smoothly. It does not need to be time-consuming and labor-intensive to disassemble, or even destroy the overall structure, and can achieve non-destructive disassembly. At the same time, when removing the inner ring 300 and the outer ring 200, the movement direction of pressing the outer ring 200 is opposite to the movement direction of taking out the inner ring 300 and the outer ring 200, which can effectively eliminate the possibility of consumers' misoperation in daily use of the watch. In addition, the watch bezel rotating structure of this embodiment can also be matched with decorative rings 400 of different colors, materials, and styles, which are provided to consumers for self-replacement, meeting the diverse needs of consumers' daily wear and the fun of disassembling and assembling the bezel by themselves.

[0035] In one embodiment, the inner wall height of the bezel groove 120 on the side adjacent to the cavity 110 is greater than the inner wall height of the bezel groove 120 on the side away from the cavity 110, and a limiting ring platform 121 is provided on the top of the bezel groove 120 on the side away from the cavity 110. The outer ring surface of the outer ring 200 is raised to form a limiting protrusion 240 abutting against the limiting ring platform 121. The maximum pressing height of the outer ring 200 can be limited by the mutual constraint of the limiting ring platform 121 and the limiting protrusion 240. At the same time, the outer ring 200 is constrained by the limiting ring platform 121 and the upper limit protrusion 310 of the inner ring 300 to realize the positioning of the outer ring 200. In this embodiment, it is necessary to ensure that when the locating pin 340 abuts against the inner wall of the annular V-groove 170 and the annular step 210, the first spring 150 has not reached its maximum compression amount, and there is a distance between the limiting protrusion 240 and the limiting ring platform 121, so as to reserve a travel distance for the downward movement of the outer ring 200.

[0036] In one embodiment, the first limiting member 140 includes a first column 141 inserted into the first limiting groove 130, a first limiting block 142 fixed on the top of the first column 141, and a ball head 143 fixed on the top of the first limiting block 142 to form an abutting portion, the width of the first limiting block 142 is greater than the diameter of the first column 141, and the first spring 150 is sleeved on the first column 141, and one end of the first spring 150 abuts against the first limiting block 142, and the other end of the first spring 150 abuts against the bottom surface of the first limiting groove 130. By arranging the ball head 143 on the top of the first limiting block 142, while providing an abutting portion between the first limiting member 140 and the lower surface of the outer ring 200, the scratching of the lower surface of the outer ring 200 by the abutting portion can be reduced.

[0037] In addition, please combine Figure 2 and Fig. 9In one embodiment, a gear ring 350 is provided on the lower surface of the inner ring 300, and a plurality of check teeth are provided on the gear ring 350. The check teeth are helical teeth, and the check teeth include an inclined surface and a vertical surface set at an angle with the inclined surface; a second limiting groove 180 is also provided on the bottom surface of the bezel groove 120, and a second limiting member 181 and a second spring 182 fixedly connected to the second limiting member 181 and elastically connected to the inner surface of the second limiting groove 180 are provided in the second limiting groove 180, and the second limiting member 181 has a check portion located above the second spring 182 and cooperating with the check teeth. Further preferably, the second limiting member 181 includes a second column 1811 inserted into the second limiting groove 180, a second limiting block 1812 fixed on the top of the second column 1811, and a wedge block 1813 fixed on the top of the second limiting block 1812 and inserted between two adjacent non-return teeth to form a non-return portion, the width of the second limiting block 1812 is greater than the diameter of the second column 1811, the second spring 182 is sleeved on the second column 1811, and one end of the second spring 182 abuts against the second limiting block 1812, and the other end of the second spring 182 abuts against the bottom surface of the second limiting groove 180. By arranging a second spring 182 and a second limiting member 181 in the second limiting groove 180, the inclined surface on the wedge block 1813 abuts against the inclined surface on the helical tooth. In the process of synchronous rotation of the inner ring 300 and the outer ring 200 for timing, as the inner ring 300 rotates, the check teeth on the gear ring 350 contact the wedge block 1813 one by one. When the inner ring 300 rotates in the reverse direction, the wedge block 1813 and the vertical surfaces on the check teeth constrain each other, which can limit the reverse rotation of the inner ring 300, thereby controlling the unidirectional rotation of the inner ring 300.

[0038] In one embodiment, a plurality of first limiting grooves 130 are uniformly provided on the bottom surface of the groove of the bezel groove 120 along the circumferential direction, and a plurality of pin holes 330 are uniformly provided on the inner ring 300 along the circumferential direction of the inner ring 300. In this way, the uniformly distributed plurality of first springs 150 jointly provide an upward elastic force on the outer ring 200, and the outer ring 200 is uniformly stressed, ensuring the consistency of the movements of various parts of the outer ring 200 during the rising and falling process of the outer ring 200. Moreover, the elastic force exerted on the outer ring 200 is relatively large, so that the outer ring 200 has a relatively large rising distance under the joint action of each first spring 150, so that the operator can remove the outer ring 200 during the disassembly process. By uniformly providing a plurality of pin holes 330 on the inner ring 300, the inner ring 300 is limitedly connected to the watch case 100 through a plurality of positioning pins 340, thereby improving the stability of the connection between the inner ring 300 and the watch case 100. It should also be noted that the dimensions of the inner ring 300 and the outer ring 200 should be such that, when the inner ring 300 and the outer ring 200 are embedded in the bezel groove 120 , the inner ring 300 and the outer ring 200 can rotate in the bezel groove 120 to meet the timing requirements of the user.

[0039] In one embodiment, the lower surface of the decorative ring 400 is bonded to the upper surface of the inner ring 300. Of course, the decorative ring 400 can also be fixed to the upper surface of the inner ring 300 in other ways, for example, a slot is provided on the upper surface of the inner ring 300, and a protrusion is provided on the lower surface of the decorative ring 400. The decorative ring 400 is positioned and installed on the inner ring 300 through the concave-convex cooperation between the protrusion and the slot. Further, in this embodiment, the outer edge of the decorative ring 400 is flush with the edge of the limiting boss 310 on the side facing away from the cavity 110, or the outer edge of the decorative ring 400 protrudes from the edge of the limiting boss 310 on the side facing away from the cavity 110. In this way, the gap at the connection between the inner ring 300 and the outer ring 200 can be shielded by the decorative ring 400 to reduce the impact on the appearance of the watch.

[0040] In addition, the utility model also discloses a watch, which includes the above-mentioned non-destructive disassembly watch bezel rotating structure 10, and the watch also includes a watch movement accommodated in the cavity 110, a watch glass located in the decorative ring 400 and covered on the main surface of the watch case 100 to block the cavity 110, a bottom cover covered on the inner surface of the watch case 100 to block the cavity 110, a handle that penetrates the side wall of the watch case 100 and is inserted into the cavity 110 to connect with the watch movement, and a watch strap or bracelet fixedly connected to the outer side of the watch case 100. By setting the above-mentioned watch bezel rotating structure in the watch, while satisfying the bezel rotation, the bezel connection part is blocked, reducing the impact on the appearance of the case ring, the bezel is easy to disassemble, and the bezel can be non-destructively disassembled and replaced.

[0041] The watch bezel rotating structure and the watch for non-destructive disassembly and assembly of the utility model are implemented. A first limiting groove 130 is opened in the bezel groove 120, and a first limiting member 140 and a first spring 150 are arranged in the first limiting groove 130. At the same time, an annular V-shaped groove 170 is opened on the inner side of the bezel groove 120, a pin hole 330 is opened on the inner ring 300, and a positioning pin 340 is arranged in the pin hole 330. During assembly, the inner ring 300 equipped with the positioning pin 340 only needs to be embedded in the groove body surrounded by the inner side of the bezel groove 120 and the outer ring 200, and the inner ring 300 is pressed to move the inner ring 300 downward until the two ends of the positioning pin 340 are aligned with the inner wall and the annular V-shaped groove 170. The shaped step 210 abuts against the inner ring 300 and the outer ring 200, that is, the installation of the inner ring 300 and the outer ring 200 on the watch case 100 is realized; when disassembling, the outer ring 200 is pressed and rotated, and then the outer ring 200 and the inner ring 300 are pulled upwards to realize the disassembly of the outer ring 200 and the inner ring 300. The outer ring 200 and the inner ring 300 are easy to disassemble and assemble, and the related parts are not easily damaged during the disassembly and assembly process, thereby realizing the non-destructive disassembly and replacement of the inner ring 300 and the outer ring 200, which is beneficial to prolonging the service life of the connection structure and ensuring the stability and reliability of the installation of the inner ring 300 and the outer ring 200; the matching parts of the inner ring 300 and the outer ring 200 and the watch case 100 are blocked, reducing the impact on the appearance of the shell ring.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
