[0001] This application relates to the field of watch technology, and more specifically, to a crown and a watch. Background Technology

[0002] With the development of technology, the function of watches has gone beyond simply displaying the time. Especially in today's society, watches are not only a practical tool for telling time, but also a fashion accessory, widely used by all kinds of people.

[0003] In related technologies, the crown of a watch is usually connected to the crown tube by a snap-fit ​​mechanism, which results in low stability of the connection between the crown and the crown tube. During daily use, there is a risk that the crown may fall off. Utility Model Content

[0004] In order to at least address some of the deficiencies mentioned in the related art, this application provides a crown and a watch.

[0005] To achieve the above objectives, this application provides a crown, including a crown head and a crown tube. The crown head includes an end body and a post, the post being disposed on the end body and extending away from the end body; a straight groove is formed on the end body near the post, the direction of the straight groove being opposite to the extension direction of the post. A first sealing element is provided at the bottom of the straight groove, and an external thread is provided on the post from the first sealing element away from the end body. An internal thread is provided on the inner wall of the crown tube, which mates with the external thread, and the crown tube is threadedly connected to the post; when the crown tube is threadedly connected to the post, one end of the crown tube extends into the straight groove and abuts against the first sealing element.

[0006] Furthermore, the column comprises a first segment and a second segment, with a step provided at the connection between the first segment and the second segment. One end of the first segment extends into the straight groove, and the external thread is provided on the outer wall of the first segment.

[0007] Furthermore, the length of the tube is L1, and the distance between the first seal and the step is L2, satisfying: L1 = L2.

[0008] Furthermore, a first groove is formed on the inner wall of the tube, and a second sealing element is embedded in the first groove, which can abut against the column.

[0009] Furthermore, the second seal includes a sealing ring, and multiple sealing rings are disposed in the first groove, with adjacent sealing rings abutting against each other.

[0010] Furthermore, the second seal protrudes outward from the first groove in the direction of the column.

[0011] Furthermore, a second groove is provided on the column, and a third sealing element is embedded in the second groove. The third sealing element can extend to the outside of the second groove and abut against the inner wall of the tube.

[0012] Furthermore, multiple first grooves are provided on the inner wall of the tube, and multiple second grooves are provided on the column. The first grooves and the second grooves are arranged alternately.

[0013] Furthermore, the outer wall of the tube is provided with a protrusion that can extend into the straight groove, and the edge of the protrusion is flush with the edge of the straight groove.

[0014] This application also provides a watch, including a dial and a crown as described in any of the above embodiments, the crown being mounted on the dial.

[0028] This embodiment provides a crown to solve the problem in related technologies where the crown head 100 and the crown tube 200 are easily detached.

[0029] Please see Figures 1 to 4A crown includes a crown head 100 and a crown tube 200. The crown head 100 includes an end body 110 and a post 120. The post 120 is disposed on the end body 110 and extends away from the end body 110. A straight groove 111 is formed on the end body 110 near the post 120, and the direction of the straight groove 111 is opposite to the direction of extension of the post 120. A first sealing element 112 is provided at the bottom of the straight groove 111. An external thread is provided on the post 120 from the first sealing element 112 away from the end body 110. An internal thread that mates with the external thread is provided on the inner wall of the crown tube 200. The crown tube 200 is threadedly connected to the post 120. When the crown tube 200 is threadedly connected to the post 120, one end of the crown tube 200 extends into the straight groove 111 and abuts against the first sealing element 112.

[0030] Specifically, in this embodiment, the bar tube 200 is fitted onto the cylinder 120 of the bar head 100, and the internal thread of the bar tube 200 mates with the external thread of the cylinder 120 to form a threaded connection. The bar tube 200 is then installed on the bar head 100. This threaded connection improves the reliability of the connection between the bar head 100 and the bar tube 200. Compared to the snap-fit ​​connection of the bar head 100 and the bar tube 200 in related technologies, the connection method in this embodiment is more stable, making it less likely for the bar head 100 and the bar tube 200 to detach, thus improving the stability of this embodiment.

[0031] After the crown tube 200 is installed on the crown head 100, one end of the crown tube 200 extends into the straight groove 111 and abuts against the first seal 112. The first seal 112, after being squeezed and compressed, fills the tiny gap between the crown tube 200 and the straight groove 111. This effectively prevents moisture, dust, and other impurities from entering the crown, improving its water and dust resistance. Furthermore, when the crown tube 200 is screwed into the crown body 120 and the seal is pressed tightly, the reverse elastic force generated by the seal increases the friction at the connection point. This elastic pre-tightening force helps prevent loosening due to vibration or frequent operation, making the connection between the crown tube 200 and the crown head 100 more secure.

[0032] Please see Figure 1 , Figure 2 The column 120 includes a first segment 121 and a second segment 122, with a step 123 at the connection between the first segment 121 and the second segment 122. One end of the first segment 121 extends into the straight groove 111, and an external thread is provided on the outer wall of the first segment 121. The step 123 structure can play an axial limiting role during the watch assembly process to prevent the bar 100 from being installed too deep or not in place. During assembly, when the step 123 abuts against the surface of the end body 110, it indicates that the column 120 has been correctly installed, avoiding poor sealing or loose connection caused by assembly errors.

[0033] In this embodiment, the first segment 121 has a larger diameter and serves as the main load-bearing component, providing structural support from the entire bar head 100. The threaded design on the first segment 121 effectively improves the overall strength of the thread, preventing damage or breakage during use and ensuring normal operation. This segment extends into the straight groove 111, saving external space and resulting in a more compact and aesthetically pleasing overall appearance.

[0034] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the length of the bar tube 200 is L1, and the distance between the first seal 112 and the step 123 is L2, satisfying L1 = L2. By limiting the length of the bar tube 200 and the length of its installation position on the column 120, when L1 = L2, after the bar tube 200 is fully screwed in, its end face just contacts the first seal 112 and begins to apply pressure, thereby ensuring the sealing performance between the bar head 100 and the bar tube 200, as well as the reliability of their connection. This avoids excessive compression that could lead to excessive deformation or even damage to the first seal 112; it also avoids insufficient compression that could cause seal failure.

[0035] In threaded connections, problems of "over-tightening" or "under-tightening" can easily occur due to uneven force applied by the operator. In this embodiment, the design of L1=L2 provides the operator with a mechanical stop point, that is, when the end of the bar tube 200 abuts against the seal, it cannot be screwed in further, which naturally limits the screwing depth and makes this embodiment easy to assemble.

[0036] Furthermore, during the installation of the Bar pipe 200, because there is a clear "bottoming sensation", the operator can sense whether it has been in place during manual or automatic assembly; this can be used as a standard for judging whether the installation is complete.

[0037] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, a first groove 210 is formed on the inner wall of the crown tube 200, and a second sealing element 211 is embedded in the first groove 210. The second sealing element 211 can abut against the column body 120. In addition to the initial seal provided by the first sealing element 112, the second sealing element 211 further enhances the sealing performance of the entire connection part. This further improves the sealing effect of this embodiment and provides more effective protection for the inside of the crown.

[0038] The presence of the second seal 211 can effectively prevent external moisture and dust from entering the crown. Especially since the first seal 112 is a squeezed seal and may wear or age due to prolonged use, the second line of defense can effectively improve the product's durability and service life.

[0039] Furthermore, the second seal 211 provides an additional seal while also generating a certain amount of friction, which helps to fix the position of the bar tube 200 and reduce accidental loosening due to vibration or other external factors.

[0040] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the second seal 211 includes multiple sealing rings disposed within the first groove 210, with adjacent sealing rings abutting against each other. The arrangement of multiple sealing rings provides multi-layered sealing protection. Even if one sealing ring is damaged or ages, the other sealing rings can still maintain an effective seal, greatly enhancing waterproof, dustproof, and other sealing performance.

[0041] Multiple sealing rings can also play a role in pressure dispersion. That is to say, when the bar tube 200 is tightened, multiple sealing rings can more evenly distribute the pressure applied to the column 120, avoiding premature wear or failure of a single sealing ring due to excessive local pressure.

[0042] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the second seal 211 protrudes outward from the first groove 210 towards the column 120. When the bar tube 200 is screwed into the column 120, the protruding sealing ring will first contact the surface of the column 120. That is, during installation, the sealing ring can begin to perform its sealing function, reducing the potential risk of leakage due to incomplete tightening.

[0043] It is also important to note that because the second sealing ring protrudes and directly contacts the column 120, the friction between the bar tube 200 and the column 120 is further increased. Furthermore, in this embodiment, the bar head 100 and the bar tube 200 not only improve connection strength and reliability through threaded engagement, but also benefit from the first sealing element 112, which compresses the bar tube 200 in the horizontal direction, increasing the friction between the bar tube 200 and the bar head 100 in the horizontal direction to improve connection reliability. The second sealing element 211 further increases the friction between the bar tube 200 and the column 120 in the circumferential direction, enhancing the connection reliability and ensuring that the bar tube 200 does not easily detach from the bar head 100. It also effectively prevents the bar tube 200 from loosening due to vibration or other external forces during use.

[0044] In one embodiment, for example, a second groove is formed on the column 120, and a third seal is embedded in the second groove. The third seal extends out of the second groove and abuts against the inner wall of the crown tube 200. In addition to the sealing effect provided by the original first seal 112 and second seal 211, the third seal adds an extra layer of protection. This three-layer sealing mechanism can significantly improve the protection capabilities such as water and dust resistance, ensuring the safety of the internal components of the crown.

[0045] The third seal is in direct contact with the inner wall of the tube 200, effectively filling the tiny gap between the column 120 and the tube 200, helping to prevent the intrusion of any fine particles or moisture.

[0046] When the third seal is compressed, it generates a certain frictional force on the inner wall of the bar tube 200. This frictional force also helps to fix the position of the bar tube 200 and prevent it from loosening unexpectedly due to external factors.

[0047] In one embodiment, for example, the specific structure or material of the first seal 112, the second seal 211, and the third seal can be arbitrarily selected from existing structures or materials according to actual conditions. For example, in this embodiment, the first seal 112 can be made of fluororubber or silicone rubber. Both of these materials have good elasticity, chemical corrosion resistance, aging resistance, and excellent temperature stability. Since the first seal 112 needs to withstand a certain amount of compression to achieve a sealing effect, selecting a material with good elasticity and aging resistance can ensure the service life of the first seal 112. The second seal 211 and the third seal can be made of fluororubber or nitrile rubber. Among them, nitrile rubber is widely used in dynamic sealing scenarios due to its good wear resistance and resistance to water and grease. In this embodiment, the second seal 211 and the third seal may be dynamically compressed due to slight relative movement between the bar tube 200 and the column 120. Therefore, a material that is both soft and wear-resistant is selected to ensure long-term effective sealing, while also taking into account the friction between the bar tube 200 and the column 120, so as to ensure the reliability of the connection between the bar tube 200 and the column 120.

[0048] It should also be noted that, due to the buffering effect of the first seal 112, the direct impact and wear on the threaded portion of the tube 200 when it is installed on the column 120 are reduced, thereby slowing down the rate of thread aging or damage. At the same time, the second seal 211 and the third seal can also reduce the hard contact between the metal parts of the tube 200 and the column 120, further reducing the risk of wear.

[0049] In one embodiment, for example, multiple first grooves 210 are provided on the inner wall of the bar tube 200, and multiple second grooves are provided on the column 120. The first grooves 210 and the second grooves are staggered. By staggering multiple grooves and corresponding seals, multiple layers of sealing barriers can be formed at different positions, improving the sealing performance between the bar head 100 and the bar tube 200 in this embodiment. Correspondingly, providing multiple seals at different positions can also increase the friction between the bar tube 200 and the column 120 at multiple positions, thereby improving the overall connection reliability while preventing local stress concentration between the bar tube 200 and the bar head 100.

[0050] In one embodiment, exemplarily, such as Figure 4 As shown, a protrusion 220 is provided on the outer wall of the bar tube 200. The protrusion 220 can extend into the straight groove 111, and the edge of the protrusion 220 is flush with the edge of the straight groove 111. By adding a mechanical engagement structure between the protrusion and the straight groove 111 to the threaded connection, the bar tube 200 and the bar head 100 are not only secured by threads but also by a physical interlocking structure. This dual fixing method significantly improves the overall connection's robustness, especially in this embodiment where it is part of a watch and requires frequent operation.

[0051] The engagement of the protrusion and the straight groove 111 can also serve as an assembly guide structure, helping operators quickly determine the installation direction and whether it is in place, thus reducing assembly difficulty. In automated assembly, it can also serve as an assembly feature, making this embodiment easier to assemble and helping to reduce problems such as incorrect assembly or omissions.

[0052] In one embodiment, exemplarily, such as Figure 3 As shown, the outer surface of the end body 110 of the barber head 100 is uniformly textured to increase the friction when the operator operates the end body 110 of the barber head 100. The textured surface increases the coefficient of friction between the fingers and the contact surface of the barber head 100, making it easier for the operator to grasp and rotate the barber head 100.

[0053] Increased friction helps provide a more stable control experience, reduces operational errors caused by slippage, and ensures that every adjustment is accurate.

[0054] Appropriate texture design not only provides the necessary friction but also delivers a pleasant tactile feel, making operation more comfortable for the user. This is especially important for watches that frequently require manual adjustment. Furthermore, a well-designed texture can not only improve functionality but also serve as a decorative element, enhancing the overall aesthetic value of the product. Different texture patterns, such as waves and diamonds, can give products a unique visual effect and a high-end feel.

[0055] This embodiment also provides a watch, including a dial and a crown as described in any of the above embodiments, the crown being mounted on the dial.

[0056] The watch in this embodiment has the crown of any of the above embodiments, and thus has all the beneficial effects of the crown, which will not be repeated here.

[0057] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
