Description

Technical Field

[0001] This utility model relates to the field of watch strap technology, specifically a detachable three-bead watch strap structure that allows for convenient length adjustment without any tools. Background Technology

[0002] Watches have become a favorite timekeeping tool for many people. Nowadays, many people wear watch straps to add some decoration to their bodies, just like wearing rings and bracelets. Wearing a watch is also a good form of decoration. The watch strap is a general term for the part of the wrist that effectively secures the watch. Watch straps are made of a variety of materials, including soft leathers such as cowhide and crocodile skin, as well as hard materials such as copper, stainless steel, titanium alloy, and ceramic. Because people's wrists are different in size, watch straps are manufactured according to the largest wrist size. Therefore, after purchasing a watch, most people need to remove a certain number of strap links to adjust the length of the strap in order to wear the watch properly on their wrist.

[0003] Most watch straps on the market are connected by steel pins, hairpins, or screws. Disassembling a watch strap requires a screwdriver or special tools to remove these pins and screws. While professional staff in physical stores can handle this for customers, in today's highly developed e-commerce environment, adjusting the length of a watch strap purchased online is a troublesome and difficult task for many consumers. Therefore, this paper proposes a detachable watch strap that allows consumers to adjust the strap length themselves without any tools, thus solving the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable three-bead watch strap structure, which has the advantages of allowing consumers to adjust the strap length themselves without using any tools, thus solving the problem of the cumbersome and difficult process of adjusting the strap length when shopping online.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable three-bead watch strap structure, including a watch strap, the watch strap being composed of fixed beads and detachable beads, the detachable beads being composed of a first bead, a second bead and a third bead, the second bead and the third bead being on both sides of the first bead and symmetrical to each other, commonly known as a three-bead strap.

[0006] The first bead has an adjustment component inside, which includes a circular slider inside the first bead. A steel needle with teeth at the top is fixed to the upper end of the circular slider. A spring is sleeved on the outer surface of the steel needle. A fixing hole is provided below the second bead, and a short rotating shaft is provided on the lower left side. A double-toothed steel needle is provided at the bottom of the first bead. The double-toothed steel needle is inserted into a third bead below the first bead and fixedly connected to the third bead by an interference fit. A long rotating shaft is fixed to the upper left side of the third bead.

[0007] Furthermore, the first bead has a circular groove inside, and the spring, circular slider and steel needle are located inside the circular groove. There is a through hole above the circular groove that matches the size of the steel needle.

[0008] Furthermore, the toothed end of the steel needle extends to the outside of the circular groove, passes through the through hole above the circular groove, and is inserted into the fixing hole below the second bead and fastened by interference fit.

[0009] Furthermore, the double-toothed steel needle securely connects the first and third beads via an interference fit.

[0010] Furthermore, the spring is located between the circular slider and the top of the circular groove, and the outer diameter of the spring and the circular slider is smaller than the inner diameter of the circular groove. Under the action of the spring, the circular slider can slide up and down in the circular groove.

[0011] Furthermore, the short rotating shaft on the upper left and the long rotating shaft on the lower left of the two adjacent detachable belt beads can be simultaneously inserted into the through hole on the right side of the left belt bead to limit the left belt bead; the second belt bead can be pulled upward and separated from the first belt bead by a certain distance. After the second belt bead is pulled upward and the short steel needle on the lower left side of the second belt bead is disengaged from the through hole on the right side of the first belt bead, the second belt bead and the steel needle on the circular slider can rotate 360 ​​degrees.

[0012] Furthermore, the second bead is pulled upwards and rotated 90 degrees. The short pivot on the lower left side of the second bead rises and rotates accordingly, which releases the restriction on the left bead. The left bead can then be removed upwards, allowing the watch strap length to be adjusted.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This detachable three-link watchband structure involves first inserting the long pivot on the upper left of the third link into the through hole on the right side of the first link, and then inserting the short pivot on the lower left of the second link into the through hole from above to limit the other link. Under the action of the circular slider, steel pin, and spring, the second link can move up and down. By pulling out and rotating the second link and its left short pivot, the restriction on the adjacent link can be released, allowing for easy removal of the adjacent link and convenient adjustment of the watchband length. It is convenient, quick, and requires no tools; consumers can operate it themselves. Attached Figure Description
