[0034] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0035] Example 1

[0036] Reference Figures 1 to 9 A quick-release optical pin type watch strap bead includes two side beads and a central bead 1. The two side beads are spaced apart, and the central bead 1 is located between the two side beads. One end of each side bead is connected to the other structure of the watch strap via an optical pin 4. A rotating rod 51 is rotatably and elastically connected to the central bead 1. The other end of one side bead is connected to the central bead 1 via a pin body 52. ​​The other end of the other side bead is sleeved on the part of the rotating rod 51 that extends outside the central bead 1, so as to pull the side bead sleeved on the rotating rod 51 outward so that it can be separated from the optical pin 4 and rotated, thereby facilitating the installation and removal of the optical pin 4.

[0037] Reference Figure 1 , Figure 2 and Figure 5The two edge beads are specifically a rotating edge bead 2 and a locking edge bead 3. Both rotating edge bead 2 and locking edge bead 3 are elongated blocks and are spaced apart. The middle bead 1 is located between rotating edge bead 2 and locking edge bead 3. Both rotating edge bead 2 and locking edge bead 3 have a new ear hole 32 and an insertion hole 31 on their sides near the middle bead 1. Rotating edge bead 2 is rotatably and elastically connected to the middle bead 1 through a rotating rod 51. Locking edge bead 3 is locked to the middle bead 1 through a needle body 52 (i.e., locking edge bead 3 cannot rotate). In this embodiment, the middle bead 1 is a single structure. The middle bead 1 is staggered relative to the locking edge bead 3 and rotating edge bead 2. The middle bead 1 is also elongated and has a needle hole 12 and a new ear piercing hole 11 through it. The light needle 4 passes through the new ear piercing hole 11 of the middle bead 1, and the two ends of the light needle 4 are respectively inserted into the insertion hole 31 of the locking edge bead 3 and the insertion hole 31 of the rotating edge bead 2. The entire light needle 4 is located outside the middle bead 1.

[0038] Reference Figures 2 to 7 The needle body 52 passes through the growth ear piercing hole 11 of the middle bead 1. A cavity is provided at one end of the needle body 52 near the rotating rod 51. The end of the rotating rod 51 near the needle body 52 extends coaxially into the cavity and is elastically connected to the needle body 52 to form a growth ear needle 5. This growth ear needle 5 is arranged parallel to the light needle 4. In this utility model, the needle body 52 includes a growth ear rod 522, a growth ear tube 521, and a sleeve 523. The growth ear tube 521 is tubular and both ends are hollowed out. A first annular locking platform 5211 is formed by an inward protrusion of the inner wall of the spring ear tube 521 near the opening of the locking bead 3. A second annular locking platform 5212 is formed by an inward protrusion of the inner wall of the spring ear tube 521 near the opening of the rotating bead 2. The middle bead 1 is fitted onto the spring ear tube 521 (i.e., the spring ear tube 521 passes through the spring ear perforation 11 of the middle bead 1). The spring ear rod 522 and the sleeve 523 are both coaxially arranged with the spring ear tube 521. The spring ear rod 522 is rod-shaped. One end of the spring bar 522 is inserted into the spring bar hole 32 of the locking bead 3, and the other end of the spring bar 522 is located inside the spring bar tube 521. A first annular groove 5221 is provided on the outer wall of the portion of the spring bar 522 located inside the spring bar tube 521. A first locking platform 5211 engages with the first locking groove 5221 to prevent the spring bar 522 from moving axially along the spring bar tube 521. The sleeve 523 is annular and located at the rotation opening of the spring bar tube 521 (the spring bar tube 521 is close to...). The opening at one end of the rotating bead 2 is its rotating opening. A second annular groove 5231 is provided on the outer wall of the sleeve 523. The second groove 5231 cooperates with the second locking platform 5212 to prevent the sleeve 523 from moving along the axial direction of the ear tube 521. The sleeve 523, the ear tube 521 and the ear rod 522 together form the cavity. One end of the rotating rod 51 extends into the cavity, and the other end of the rotating rod 51 is inserted into the ear hole 32 of the rotating bead 2.

[0039] Reference Figure 2 , Figure 4and Figure 5 In order to enable the rotating rod 51 to rotate and bead 1 to be elastically connected, a spring 53 is provided in the cavity formed by the ear tube 521, ear rod 522 and sleeve 523. The spring 53 is sleeved on the rotating rod 51. One end of the spring 53 elastically presses against the step on the rotating rod 51, and the other end of the spring 53 elastically presses against the sleeve 523, so that the rotating rod 51 is elastically connected to the sleeve 523 through the spring 53.

[0040] Reference Figures 1 to 9 The method of using the quick-release optical pin watch strap beads in this embodiment is as follows:

[0041] When it is necessary to remove the needle 4, the user only needs to manually pull the rotating bead 2 outward. The rotating rod 51 moves outward with the rotating bead 2, and the spring 53 is compressed until the end of the needle 4 near the rotating bead 2 exits from the insertion hole 31 of the rotating bead 2, so that the needle 4 is detached from the rotating bead 2 and suspended in the air. Then, the rotating bead 2 can be manually rotated downward. At this time, the rotating rod 51 rotates with the rotating bead 2 around the central axis of the spring tube 521 at a certain angle (e.g., Figure 8 (As shown), move the end of the rotating bead 2 away from the rotating rod 51 away from the light needle 4, and the light needle 4 can be removed;

[0042] When it is necessary to install the light needle 4, pull out the rotating bead 2, then rotate the rotating bead 2, and then release it. One end of the light needle 4 can then be inserted into the insertion hole 31 of the locking bead 3. Pull out the rotating bead 2 again, and rotate the rotating bead 2 in the opposite direction so that the insertion hole 31 of the rotating bead 2 is aligned with the other end of the light needle 4. Release the rotating bead 2, and the rotating bead 2 will move closer to the middle bead 1 under the action of the spring 53, so that the other end of the light needle 4 can be inserted into the insertion hole 31 of the rotating bead 2. The light needle 4 can then be installed between the two beads.

[0043] When it is necessary to assemble two watch strap beads together, the user only needs to pull outward and rotate the rotating side bead 2 of one of the watch strap beads to remove the optical pin 4 of that watch strap bead. Then, insert the optical pin 4 into the pin hole 12 of the other watch strap bead, move the other watch strap bead so that the center bead 1 of the other watch strap bead is located between the two side beads of the first watch strap bead, and then put back the original optical pin 4 to install the two watch strap beads together.

[0044] Example 2

[0045] Reference Figures 10 to 14This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the middle bead 1 in this embodiment includes at least one set of beads. Some beads are connected to two edge beads through optical needles 4, and all beads are connected to two edge beads through needles 52. Preferably, this embodiment has one set of beads, which includes three beads. Each bead is elongated. Specifically, the three beads are a first bead 13 and two second beads 14. The first bead 13 is located between the two second beads 14 and is staggered from the two second beads 14. The optical needle 4 is located outside the two second beads 14. One end of the first bead 13 is connected to the two edge beads through the optical needle 4. Specifically, the optical needle 4 passes through the needle hole 12 of the first bead 13, and the two ends of the optical needle 4 are respectively... Inserted into the spring bar hole 32 of the locking bead 3 and the spring bar hole 32 of the rotating bead 2, the other end of the first bead 13 and the two second beads 14 are connected to the two beads through the pin body 52. ​​Specifically, the first bead 13 and the two second beads 14 are both sleeved on the outside of the spring bar tube 521. The spring bar tube 521 passes through the spring bar holes 11 of the two second beads 14 and the spring bar holes 11 of the first bead 13. The part of the spring bar 522 located outside the spring bar tube 521 is inserted into the insertion hole 31 of the locking bead 3. The pin holes 12 on the two second beads 14 are used to connect with the optical pins 4 of other watch strap beads. Other structures are the same as in the first embodiment. The method of using the quick-release optical pin watch strap beads in this embodiment is also basically the same as in the first embodiment, and will not be described here.

[0046] This invention relates to a quick-release optical pin type watch strap bead, in which one of the side beads is elastically connected to the central bead 1 via a rotating rod 51. Users do not need to use special tools; they can simply pull and rotate the side bead to detach it from the optical pin 4, thus quickly installing and removing the optical pin 4. This achieves rapid and convenient installation and removal of the watch strap beads, greatly improving the convenience, flexibility, and efficiency of watch strap adjustment, and meeting users' needs for quick watch strap adjustment and personalized wearing.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
