Description

Technical Field

[0001] The utility model relates to the technical field of watches, in particular to a watch buckle and a watch. Background Art

[0002] The clasp is a crucial component of a watch, used to adjust the tightness of the watch for easy wearing and removal. Women's watches designed like jewelry bracelets often use a snap-on clasp to adjust the strap length while also meeting the watch's aesthetic requirements. These clasps utilize an interference fit between a barb and a steel pin to lock the clasp. However, they lack a safety feature that prevents loosening, making it difficult to control the tightness of the clasp. This results in the clasp being either too tight when engaged and too loose when engaged or too loose when engaged. This can easily cause the clasp to accidentally open due to external forces, friction, or collisions during daily wear, potentially causing the watch to fall off and become damaged. Furthermore, due to the small size of the clasp, consumers often need to use their fingernails to pry it open, which can easily damage their fingernails and negatively impact the user experience. Furthermore, due to the limited size of the clasp, it can be difficult for consumers to align the clasp with the strap's buckle when operated with one hand, making it difficult to secure and secure the clasp, further impacting the user experience.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Please combine Figure 1-4The utility model discloses a watch clasp that is difficult to accidentally loosen, easy to fasten, and does not damage nails. The watch clasp is intended to be installed between two watch straps 10 on either side of the watch, that is, the watch clasp is used to connect the watch straps 10 on both sides of the watch so that the watch can be worn on the wrist of the consumer. The end of the watch strap 10 on one side has a first end 101, and the end of the watch strap 10 on the other side has a second end 102. The first end 101 and the second end 102 are used to connect the watch strap 10 to the watch clasp. The watch clasp includes a clasp base 100, a clasp cover 200, a stopper assembly 300, and a hook 400. The clasp base 100 is connected to the first end 101 of the watch strap 10 on one side and forms the first fastening unit of the watch clasp. The clasp cover 200 and the hook 400 are both connected to the second end 102 of the watch strap 10 on the other side and, together with the stopper assembly 300, form the second fastening unit of the watch clasp. The lower surface of the buckle bottom 100 (i.e., the side of the buckle bottom 100 facing away from the buckle cover 200) is in contact with the consumer's skin or faces the consumer's wrist when worn, and the limiting component 300 is installed on the buckle cover 200 and is detachably connected to the buckle bottom 100 to achieve a first connection between the first buckling unit and the second buckling unit; the upper surface of the buckle cover 200 (the side of the buckle cover 200 facing away from the buckle bottom 100) is facing away from the consumer's wrist when worn, and the buckle cover 200 is used to provide support for the limiting component 300 and protect the limiting component 300; the hook 400 is detachably connected to the buckle bottom 100 to achieve a second connection between the first buckling unit and the second buckling unit, thereby increasing the stability of the watch buckle structure after buckling.

[0034] Please see further Figure 1-10One end of the buckle base 100 is hingedly connected to the first end piece 101, and the other end of the buckle base 100 is provided with a buckling portion adjacent to the second end piece 102. The upper surface of the buckle base 100 is provided with a limiting pin 110 extending along the thickness direction of the buckle base 100, that is, the limiting pin 110 extends in a direction away from the upper surface of the buckle base 100. An annular limiting groove 120 is defined in the middle ring side of the limiting pin 110. A shoulder is formed on the inner side of the annular limiting groove 120 adjacent to the top of the limiting pin 110. The width of the limiting pin 110 gradually increases from the top surface of the limiting pin 110 to the shoulder, that is, the top of the limiting pin 110 is approximately conical. The buckle cover 200 is located above the buckle base 100, and its cross-section is N-shaped. Specifically, the buckle cover 200 includes a top cover 210 and two baffles 220 located below and oppositely disposed on either side of the top cover 210. The top cover 210 is used to shield the upper portion of the position-limiting assembly 300, while the baffles 220 are used to install and position the position-limiting assembly 300 while also shielding both sides of the position-limiting assembly 300. Preferably, in this embodiment, the top cover 210 is an arc-shaped structure, and the baffles 220 are fixed to the edge of the top cover 210 and extend along the arc, so that the buckle cover 200 can adapt to the shape of the consumer's wrist. One end of the buckle cover 200 is hingedly connected to the second tail 102, and the other end of the buckle cover 200 can be rotated relative to the second tail 102 and covered on the buckle base 100. A pressing hole 230 connected to the inner cavity of the buckle cover 200 is respectively provided on the two opposite outer walls of the buckle cover 200 (i.e., the outer side of the baffle 220), and the line connecting the middle parts of the two pressing holes 230 is parallel to the width direction of the buckle cover 200.

[0035] The limiting assembly 300 includes a cylindrical press-protection box 310 housed within the inner cavity of the buckle cover 200, two buttons 320 centrally symmetrically disposed within the cylindrical press-protection box 310, and two springs 330 disposed opposite each other within the cylindrical press-protection box 310. The openings at both ends of the cylindrical press-protection box 310 correspond to the two press holes 230. Thus, while the sidewalls of the cylindrical press-protection box 310 limit the buttons 320 and springs 330, the openings at both ends of the cylindrical press-protection box 310 provide a mating channel for the buttons 320 and the buckle cover 200. Furthermore, the two end surfaces of the cylindrical press-protection box 310 correspond to the two opposing inner side surfaces of the buckle cover 200, ensuring that the cylindrical press-protection box 310 fully protects the buttons 320 and springs 330, preventing the side edges of the buttons 320 from falling out of the cylindrical press-protection box 310 and ensuring effective mating between the buttons 320 and the springs 330. The lower surface of the cylindrical press protection box 310 is provided with a first through hole 311 which is in communication with the inner cavity of the cylindrical press protection box 310. The button 320 includes a limiting portion 321 which is located in the cylindrical press protection box 310 and abuts against the edge of the pressing hole 230, a pressing portion 322 which is fixed on the limiting portion 321 and faces away from the inner cavity of the cylindrical press protection box 310 and passes through the pressing hole 230, and a pressing portion 323 which is eccentrically arranged on the limiting portion 321 and faces the cylindrical press protection box 310. An L-shaped hook 323 is bent toward the center of the cylindrical pressing protective box 310 from one side of the inner cavity of the protective box 310. The L-shaped hooks 323 of the two buttons 320 together define a locking limit space 324 that communicates with the first through-hole 311. A spring 330 is disposed outside the locking limit space 324 and between the limiting portions 321 of the two buttons 320. The ends of the spring 330 abut against the edges of the limiting portions 321 of the two buttons 320. The spring 330 provides a restoring force to reset the button 320, allowing it to rebound after the pressure is removed. When subjected to external pressure, the button 320 moves toward the center of the cylindrical pressing protective box 310. This gradually increases the locking limit space 324 formed by the L-shaped hooks 323 of the two buttons 320, thereby facilitating the rotation and lifting of the buckle cover 200. The hook 400 is located below the buckle cover 200. One end of the hook 400 is hingedly connected to the second end piece 102. The other end of the hook 400 is provided with a hook portion 410 that can rotate relative to the second end piece 102 and engage with the hook portion. When the buckle cover 200 is closed on the buckle base 100, the limit pin 110 is inserted into the locking limit space 324 through the first through hole 311, and the shoulder of the limit pin 110 abuts the upper surface of the L-shaped hook 323.

[0036] When the watch buckle is fastened, the hanging part 410 of the hook 400 is first hung on the fastening part of the buckle bottom 100 to realize the first connection between the first fastening unit and the second fastening unit; then the buckle cover 200 is rotated so that the free end of the buckle cover 200 rotates toward the direction close to the buckle bottom 100, and when the top of the limiting pin 110 is inserted into the lower part of the clamping limiting space 324 through the first through hole 311 on the lower surface of the cylindrical pressing protection box 310, the top of the limiting pin 110 squeezes and pushes the L-shaped hook 323 of the button 320, so that the two buttons 320 move toward the center of the cylindrical pressing protection box 310, and the clamping The limiting space 324 gradually increases, and the spring 330 is compressed by the joint extrusion of the two buttons 320; when the buckle cover 200 rotates until the top of the limiting pin 110 moves above the button 320, the extrusion of the top of the limiting pin 110 on the L-shaped hook 323 is released, and the spring 330 is reset. The L-shaped hook 323 is pushed by the spring 330 and is inserted into the annular limiting groove 120. The shoulder of the limiting pin 110 abuts against the upper surface of the L-shaped hook 323, thereby realizing the limiting cooperation between the limiting pin 110 and the button 320. In other words, the second connection between the first buckling unit and the second buckling unit is realized to complete the buckling of the watch buckle. When the watch clasp is opened, the pressing parts 322 of the two buttons 320 are pressed at the same time, so that the buttons 320 move toward the center of the cylindrical pressing protection box 310, and the clamping limit space 324 gradually increases, so that the L-shaped hook 323 disengages from the annular limit groove 120, releasing the constraint of the L-shaped hook 323 on the limit pin 110, and then the buckle cover 200 is lifted in the reverse direction, so that the free end of the buckle cover 200 rotates in the direction away from the buckle bottom 100, until the limit pin 110 is completely disengaged from the first through hole 311 on the lower surface of the cylindrical pressing protection box 310, so as to separate the buckle bottom 100 and the buckle cover 200, and finally the hook 400 is removed from the buckling part of the buckle bottom 100, that is, the watch clasp is disassembled.

[0037] In one embodiment, the top of the retaining pin 110 has a spherical, conical, frustum, or mushroom-shaped structure; the L-shaped hook 323 is provided with a guide slope 325 that slidably engages with the side surface of the top of the retaining pin 110. The width of the engaging and limiting space 324 gradually decreases from the lower surface of the button 320 to the upper surface of the button 320. It can be understood that the engaging and limiting space 324 has a flared structure that is narrow at the top and wide at the bottom, while the top of the retaining pin 110 has a conical structure that is narrow at the top and wide at the bottom. Thus, when the retaining pin 110 is inserted into the engaging and limiting space 324 through the lower portion of the engaging and limiting space 324, the side of the retaining pin 110 presses against the guide slope 325 of the L-shaped hook 323, providing the L-shaped hook 323 with a thrust along the width direction of the buckle cover 200, thereby enabling the button 320 to move relative to the buckle cover 200 and adjusting the size of the engaging and limiting space 324. Furthermore, in one embodiment, the limiting pin 110 is riveted and fixed to the buckle bottom 100. In another embodiment, the limiting pin 110 and the buckle bottom 100 are integrally formed.

[0038] Please combine Figure 1-5 as well as Figure 10-11 Two first lugs 130 are oppositely arranged at one end of the buckle base 100, and a first through-hole 131 is respectively opened on the two first lugs 130, and an embedding area 132 for inserting the first tail 101 is provided between the two first lugs 130; two second lugs 140 are oppositely arranged at the other end of the buckle base 100, and a second through-hole 141 is respectively opened on the two second lugs 140; the watch buckle also includes a first connecting pin 150 that passes through the first through-hole 131 and the first tail 101 to connect the buckle base 100 and the first tail 101, and a second connecting pin 160 that passes through the two second through-holes 141 and forms a buckling portion between the two second lugs 140. Furthermore, the first connecting pin 150 includes a first through-tube 151 that passes through the first tail 101 and abuts the inner sidewalls of the two first lugs 130, and a first through-pin 152 that passes through the first through-tube 151. The two ends of the first through-pin 152 are respectively inserted into the first through-holes 131 of the two first lugs 130. The outer wall of the first through-pin 152 is provided with a first groove, and the inner wall of the first through-tube 151 is provided with a first protrusion that matches the first groove. The second connecting pin 160 includes a second through-tube 161 that is located between the two second lugs 140 and abuts the inner sidewalls of the two second lugs 140, and a second through-pin 162 that passes through the second through-tube 161. The two ends of the second through-pin 162 are respectively inserted into the second through-holes 141 of the two second lugs 140. The outer wall of the second through-pin 162 is provided with a second groove, and the inner wall of the second through-tube 161 is provided with a second protrusion that matches the second groove. That is to say, the first connecting pin 150 and the second connecting pin 160 have the same structure. The first connecting pin 150 and the second connecting pin 160 are actually a mother-and-child through-hole. When the watch buckle is installed, the through-tube is clamped between the two lugs to limit the through-tube along the width direction of the watch strap 10. After the through-pin is inserted into the through-tube, the concave-convex cooperation of the grooves and protrusions between the through-tube and the through-pin is used to achieve mutual limitation between the through-tube and the through-pin. At this time, the through-pin is used to position the through-tube to prevent the through-tube from falling off between the two lugs. At the same time, the through-tube is used to position the through-pin to prevent the through-pin from falling off from the connecting part of the first tail particle 101 and the buckle bottom 100 or from the buckle bottom 100, thereby realizing the connection between the first tail particle 101 and the buckle bottom 100 and the setting of the buckling part on the buckle bottom 100.

[0039] The cylindrical press-protection box 310 is used to limit the position of the spring 330 and the button 320. In this embodiment, the cylindrical press-protection box 310 has a rectangular ring structure. The length of the cylindrical press-protection box 310 is equal to the width of the buckle cover 200. The corners of the outer surface of the cylindrical press-protection box 310 are all rounded to reduce scratches on the inner surface of the buckle cover 200 caused by the cylindrical press-protection box 310. In one embodiment, the upper surface of the cylindrical press-protection box 310 is provided with a deformation notch 312 extending along the length of the cylindrical press-protection box 310 and penetrating the inner wall of the cylindrical press-protection box 310 and both end surfaces of the cylindrical press-protection box 310. The deformation notch 312 is used to provide a deformation avoidance space when the cylindrical press-protection box 310 is subjected to external pressure. Furthermore, in this embodiment, a second through hole 313 is formed on the upper surface of the cylindrical push-on protective case 310, communicating with the inner cavity of the cylindrical push-on protective case 310. A line connecting the middle of the second through hole 313 and the middle of the first through hole 311 is parallel to the height of the cylindrical push-on protective case 310. Providing the second through hole 313 on the upper surface of the cylindrical push-on protective case 310 prevents damage to the cylindrical push-on protective case 310 caused by the top of the retaining pin 110 impacting the inner top surface of the cylindrical push-on protective case 310 during the watch clasp fastening process, thereby extending the service life of the cylindrical push-on protective case 310.

[0040] The button 320 not only serves as a locking portion when the retaining pin 110 is engaged with the retaining assembly 300, but also acts as a "switch" when the watch clasp is opened. In this embodiment, the width of the retaining portion 321 of the button 320 is equal to the internal width of the cylindrical press-protection box 310, and the thickness of the retaining portion 321 is equal to the internal height of the cylindrical press-protection box 310. Thus, the retaining portion 321 slides with the inner wall of the cylindrical press-protection box 310 to guide the button 320 and prevent it from shaking. By arranging the two buttons 320 in a centrally symmetrical manner, after the retaining pin 110 is inserted into the engaging retaining space 324, the L-shaped hooks 323 of the two buttons 320 jointly surround the retaining pin 110, preventing the retaining pin 110 from sliding out of the engaging retaining space 324, thereby ensuring that the L-shaped hook 323 effectively retains the retaining pin 110.

[0041] The hook 400 is used to achieve pre-positioning of the buckle cover 200 and the buckle base 100 before they are fastened together, so that the limiting pin 110 can align with the first through hole 311 during the rotation of the buckle cover 200. At the same time, the hook 400 is also used to improve the stability of the connection between the first and second buckle units. The end of the hook 400 adjacent to the buckle base 100 is bent downward to form a circular arc-shaped hooking portion 410, so that the hooking portion 410 can be hooked to the buckle base 100 from above during the downward rotation of the hook 400. The end of the hook 400 away from the hooking portion 410 has two third lugs 420 arranged opposite each other, and each of the two third lugs 420 has a third through hole 421. The watch buckle also includes a third connecting pin 422 that passes through the third through hole 421 and the second end 102 to connect the hook 400 to the second end 102. Further preferably, the third connecting pin 422 is a spring pin with retractable ends. By connecting the second tail 102 and the hook 400 through the spring pin, a stable connection between the watch buckle and the strap 10 can be achieved, preventing the buckle from falling off the strap 10, and reducing the difficulty of removing the watch buckle from the strap 10.

[0042] In addition, the utility model also discloses a watch, which includes the above-mentioned watch clasp, the watch also including a watch case, a watch movement housed in the watch case, a handle passing through the side wall of the watch case and connected to the watch movement, and two watch straps 10 arranged on opposite sides of the watch case and fixedly connected to the watch case. The end of one watch strap 10 has a first end piece 101, and the end of the other watch strap 10 has a second end piece 102. The buckle base 100 of the watch clasp is hingedly connected to the first end piece 101, and the buckle cover 200 and the hook 400 are hingedly connected to the second end piece 102, thereby achieving the installation of the above-mentioned watch clasp on the watch strap 10. In this embodiment, the specific structure of the watch clasp is the same as that of the watch clasp in the previous embodiment. For details, please refer to the previous description and will not be repeated here.

[0043] The watch buckle and watch of the present invention have at least the following beneficial effects:

[0044] 1) Structural stability: Compared with traditional jewelry clasps, the added protection design of the clasp cover 200 improves structural stability.

[0045] 2) The traditional safety buckle with a buckle cover uses a relatively long foldable fork plate to connect the buckle bottom. The fork plate is clamped between the wrist and the buckle, which is not comfortable to wear. This solution adopts a connection method of buckle bottom 100 and hook 400, eliminating the fork plate, making the buckle fit the wrist better and more comfortable to wear.

[0046] 3) The watch clasp is opened and closed using a button structure. It is assembled and disassembled by pressing the button 320 and rotating the clasp cover 200 and the hook 400. Compared with the traditional jewelry clasp that is opened by fingernails, it is more user-friendly, less likely to scratch nails, and provides a better user experience.

[0047] 4) Traditional jewelry clasps need to be threaded through the tail before being fastened. Due to the small size of the jewelry clasp, it is difficult to align it with one hand, which makes the operation difficult. This solution uses a clasp cover 200 and a hook 400 to cooperate. The clasp cover 200 is larger in size, more convenient to operate, and the assembly difficulty is greatly reduced.
