[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 2-Figure 6 The figure shows a schematic diagram of an embodiment of a watch strap with a quick-release structure provided by an embodiment of the present invention. The watch strap with a quick-release structure can be assembled to the watch head 10 and can be quickly assembled and disassembled with the watch head 10. The watch strap with a quick-release structure of the present embodiment includes a watch strap body (not shown in the figure), a connecting body 20, a button 30, two telescopic needles 40 and two elastic parts 50. The above-mentioned watch strap body can be a leather watch strap, a chain watch strap, a silicone watch strap, etc. The connecting body 20 can be made of hard materials such as stainless steel and hard plastic, and has a structure connected to the watch strap body and is connected to the end of the watch strap body through the connecting structure. Combined with Figure 1 As shown, the overall shape and size of the connecting body 20 can be adapted to the shape and size of the two mounting ears 11 of the watch head 10, and the connecting body 20 can be assembled between the two mounting ears 11 of the watch head 10 after the button 30, the telescopic needle 40 and the elastic member 50 are respectively installed thereon, thereby assembling the watch strap body to the watch head 10.

[0027] The connecting body 20 has a key slot 21 and two telescopic pin holes 22, wherein the opening of the key slot 21 is located on the bottom surface of the connecting body 20 (when the watch is worn, the bottom surface of the connecting body 20 faces the human wrist), and the two telescopic pin holes 22 are respectively formed by two holes on the key slot 21 that are perpendicular to the width direction of the watch strap (such as Figure 2 The groove walls (in the direction X) extend through two side walls of the connecting body 20 perpendicular to the width of the watchband. The key slot 21 can be a rectangular parallelepiped slot located in the middle of the connecting body 20 in the width direction of the watchband. Specifically, the shape and size of the key slot 21 can be adapted to those of the key 30. To correspond to the blind holes in the mounting ears 11 of the watch head 10, the two telescopic pinholes 22 are coaxially arranged.

[0028] The button 30 includes two clamping portions 31, which are spaced apart and parallel to each other. Figure 3As shown, the inner side of each clamping portion 31 has a hook portion 34 at the top and a push slope 33 at the bottom, forming a receiving space between the hook portion 34 and the push slope 33. Furthermore, each clamping portion 31 is formed with a slot 32. The two slots 32 extend through the two clamping portions 31 along the width of the watchband, i.e., the slots 32 also extend through the hook portion 34 and the push slope 33. Specifically, each slot 32 separates the clamping portion 31 into two clamping arms (the slot 32 is located between the two clamping arms), meaning that the button 30 consists of a press plate and four clamping arms located on the same side of the press plate. To ensure structural strength, the button 30 can be integrally formed from a hard material such as stainless steel. Those skilled in the art will appreciate that, in order to convert the sliding movement of the key 30 along the depth direction of the key slot 21 into the axial movement of the retractable pin 40, the angle between the pressing slope 33 and the depth direction of the key slot 21 is preferably between 30 and 60 degrees, with the most preferred angle being 45 degrees. The hook portion 34 can be formed by a horizontal extension of the free end of the clamping portion 31.

[0029] The two telescopic needles 40 have the same shape and size, and each telescopic needle 40 is needle-shaped (i.e., thinner column-shaped). Figure 4 As shown, the tail of each telescopic needle 40 has a slider portion 42 and a clamping section 41, and the slider portion 42 and the clamping section 41 are sequentially arranged along the axial direction of the telescopic needle 40 from the tail of the telescopic needle 40, and the radial dimension of the slider portion 42 is greater than the width of the clamping slot 32 on the button 30 (that is, the width of the clamping slot 32 in the key 30 is greater than the width of the clamping slot 32 in the key 30). Figure 3 The radial dimension of the engaging section 41 in one direction is smaller than the width of the engaging slot 32 (the radial dimension in other directions is larger than the width of the engaging slot 32), that is, the sliding portion 42 cannot pass through the engaging slot 32, while the engaging section 41 can pass through the engaging slot 32 by rotating.

[0030] Each telescopic pin 40 is mounted in a telescopic pin hole 22 of the connecting body 20 via an elastic member 50, and the tail ends of the two telescopic pins 40 are respectively inserted into the key slot 21. As will be understood by those skilled in the art, each elastic member 50 abuts against the telescopic pin 40 and the connecting body 20, and the telescopic pin 40 is slidably connected to the telescopic pin hole 22 (i.e., the telescopic pin 40 can move axially within the telescopic pin hole 22). The button 30 is mounted in the key slot 21 of the connecting body 20 and is slidably connected to the slot wall of the button slot 21. By pushing the button 30, it slides within the button slot 21 along the thickness direction of the watchband. The tail ends of the two telescopic pins 40 are respectively embedded in the card slots 32 of the two clamping parts 31 of the button 30 through the clamping sections 41. The two sliders 42 are both located between the two clamping parts 31 and are respectively limited by the hooks 34 and the pushing slopes 33 of the corresponding clamping parts 31 (that is, the two sliders 42 are respectively located in the accommodation space between the hooks 34 and the pushing slopes 33), so that the telescopic pins 40 cannot escape from the button 30. Figure 5shown.

[0031] When the button 30 is not pressed, the two elastic members 50 push the corresponding retractable pins 40 respectively, so that the head ends of the retractable pins 40 protrude from the two side walls of the connecting body 20 respectively. Figure 6 、 Figure 7 As shown, at the same time, the slider portion 42 of the telescopic needle 40 is pushed and moved by the elastic member 50, pushing the pushing inclined surface of the key 30 to move in a direction away from the bottom of the key groove 21 until the inner side surface of the slider portion 42 moves to the top of the pushing inclined surface 33 (i.e., a position close to the hook portion 34); when the key 30 is pressed (i.e., pushed toward the bottom of the key groove 21), the pushing inclined surface 33 of the clamping portion 31 of the key 30 pushes the slider portions 42 at the tail ends of the two telescopic needles 40, so that the head ends of the two telescopic needles 40 are respectively retracted into the two telescopic needle holes 22 (at the same time the elastic member 50 is compressed), as shown in FIG. Figure 7 shown.

[0032] The above-mentioned watch strap with a push-bottom quick-release structure assembles the telescopic pin 40 into the telescopic pin hole 22 of the connecting body 20 through the elastic member 50, and makes the radial dimension of the clamping section 41 at the tail of the telescopic pin 40 in one direction smaller than the width of the clamping groove 32 on the clamping portion 31 of the button 30, so that the button 30 can be assembled with the two telescopic pins 40 through the clamping section 41 of the telescopic pin 40, and at the same time, the two telescopic pins 40 are pushed axially by the pushing inclined surface 33 on the inner side of the clamping portion 31, so that the head ends of the two telescopic pins 40 are retracted into the telescopic pin hole 22, which greatly facilitates the assembly of the watch strap and the disassembly of the watch strap and the watch head.

[0033] like Figure 3 As shown, in one embodiment of the present invention, a clearance space 35 is formed between the inclined pressing surfaces 33 on the inner sides of the two clamping portions 31 on the key 30. When the tips of the two telescopic pins 40 are retracted into the telescopic pin holes 22, the clearance space 35 can accommodate the slider portions 42 at the tail ends of the two telescopic pins 40. In addition, the sum of the axial dimensions of the two engaging sections 41 and the two slider portions 42 on the two telescopic pins 40 is greater than the distance between the outer side surfaces of the two clamping portions 31 on the key 30.

[0034] In this way, when assembling the telescopic pin 40 and the button 30 to the connecting body 20, the tail end of the telescopic pin 40 is first inserted into the button slot 21 through the telescopic pin hole 22, so that the two clamping sections 41 of the telescopic pins 40 are exposed in the button slot 21, and the telescopic pin 40 is rotated so that the minimum width direction on the clamping section 41 is parallel to the length direction of the watch strap, and then the button 30 is inserted into the button slot 21 in a manner that the clamping slots 32 of the two clamping parts 31 are respectively aligned with the two clamping sections 41, and the telescopic pin 40 is released after the clamping sections 41 are embedded in the clamping slots 32; when disassembling the telescopic pin 40 and the button 30, it is only necessary to push the telescopic pin 40 further into the telescopic pin hole 22 from the two sides of the connecting body 20, for example, so that the sliding sections 42 of the two telescopic pins 40 abut against each other. At this time, the button 30 is directly removed from the button slot 21, and the telescopic pin 40 can be ejected out of the telescopic pin hole 22 under the action of the elastic member 50. The above structure greatly facilitates the assembly and disassembly of the telescopic pin 40 and the button 30 , and no additional parts are required to limit or fix the button during the assembly and disassembly process.

[0035] like Figure 4 As shown, in one embodiment of the present invention, the main body of the telescopic needle 40 is cylindrical, and the outer circumference of the tail end of the telescopic needle 40 (the portion corresponding to the engaging section 41) has two parallel axial flat surfaces 411. The distance between the two axial flat surfaces 411 is less than the width of the engaging slot 32. Accordingly, the engaging section 41 comprises the axial section where the two axial flat surfaces 411 are located, while the slider portion 42 comprises the portion between the two axial flat surfaces 411 and the free end of the tail end of the telescopic needle 40. This structure is simple to manufacture and is stable and reliable.

[0036] In particular, a sliding guide surface 421 corresponding to the pushing inclined surface 33 is formed between each axial plane 411 and the slider portion 42. The sliding guide surface 421 cooperates with the pushing inclined surface 33 to facilitate the sliding cooperation between the button 30 and the telescopic needle 40.

[0037] In addition, the tip of the telescopic needle 40 may further include a positioning pit 441 corresponding to the axial plane 411. For example, the positioning pit 441 may be offset from the axial plane 411. When the button 30 needs to be removed, the telescopic needle 40 can be rotated to a specified angle according to the positioning of the positioning pit 441, and then the button 30 can be directly removed, facilitating the disassembly and assembly of the button 30 and the telescopic needle 40.

[0038] In one embodiment of the present invention, the elastic member 50 is composed of a spring. Accordingly, each telescopic needle hole 22 is composed of a step hole, and the diameter of the tail end of the step hole (i.e., the part connected to the key slot 21) is smaller than the outer diameter of the spring, and the diameter of the main part of the step hole (i.e., the part away from the key slot 21) is larger than the outer diameter of the spring. The spring is installed in the main part of the step hole, and the tail end of the spring abuts against the end face of the tail end of the step hole. The tail end of the telescopic needle 40 passes through the central through hole of the spring and the tail end of the step hole and is inserted into the key slot 21. The above structure greatly facilitates the assembly of the elastic member 50 and the telescopic needle 40.

[0039] In one embodiment of the present invention, the head end of the telescopic needle 40 has a needle head 43 and a retaining ring segment 44 that are axially connected, and the watch strap and the watch head are assembled together by inserting the needle head 43 into the blind hole 111 of the watch head 10. The outer diameter of the retaining ring segment 44 is adapted to the diameter of the main part of the step hole (that is, the outer diameter of the retaining ring segment 44 is larger than the outer diameter of the spring), and when the telescopic needle 40 is installed in the telescopic needle hole 22, the head end of the spring abuts against the inner end face of the retaining ring segment 44. The retaining ring segment 44 can effectively prevent the spring from being dragged out of the step hole, so that the spring can better push the needle head 43 to be exposed outside the step hole. In particular, a positioning pit 441 can be provided in the retaining ring segment 44 to better indicate the position of the axial plane 411.

[0040] In one embodiment of the present invention, when the elastic member 50 pushes the head ends of the two telescopic pins out of the two telescopic pin holes, the sliders 42 of the two telescopic pins 40 push the top surface of the button 30, causing it to protrude above or become flush with the bottom surface of the connecting body 20. The distance between the top surface of the button 30 and the free end of the clamping portion 31 matches the depth of the button slot 21. This structure facilitates the removal of the watchband by pressing the button 30.

[0041] The watch strap may be a chain watch strap, and accordingly, the connecting body 20 is composed of a watch strap head bead.

[0042] The utility model also provides a watch, comprising the watch strap with the bottom-pressing quick-release structure as described above.

[0043] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
