Watchband and its joint used therein

Abstract

The present invention discloses one kind of metal catapult watch band and its joints. Each of the joints includes one first assembly, one second assembly and a casing. The second assembly has a bottom barrel with connecting part connected to the first short fork and the second short fork in the first assembly, and the casing has a cavity buckled to a casing barrel and buckled to the first and the second casing buckle tab. The first assembly in a joint has a long fork capable of being inserted into the flute of the second assembly of the next joint for connection or separated from the flute for detaching. The watch band may be detached fast and conveniently and has low cost and wide use range.

Description

technical field [0001] The invention relates to a watch strap, in particular to an easily detachable elastic watch strap. Background technique [0002] Wristwatches are generally liked by people as a timekeeper and decoration for daily use, and watches are usually mainly composed of dials and watch straps. In order to meet the wearing needs of everyone, watch manufacturers usually make the strap of the watch very long. In this way, after buying a watch, many people need to cut off the part of the strap that is too long. For this reason, the strap is usually made In a detachable manner, that is, the strap includes at least one joint, and the joints are detachable. [0003] Figures 1A-1D ,as well as Figures 2A-2D The disassembly and assembly processes of a detachable watch strap in the prior art are respectively shown. [0004] The disassembly process of the watch strap 20' includes: the first step, such as Figure 1A As shown, the watch strap 20' includes at least one j...

AI Technical Summary

Problems solved by technology

[0010] First of all, since the disassembly of the watch straps 20' and 20" first needs to loosen or pull out the clasp 12' and the sling piece 310", it needs skilled technicians to use special tools, which is inconvenient to operate;

[0011] In addition, after the joints 10' and 10" are disassembled, there are scattered joint parts (such as the face shell 300', the slingshot piece 310", etc.), so it is easy to lose parts, causing difficult assembly problems, and some individual joint parts are very small. For people with thicker fingers, it will be difficult to pick it up;

[0012] The width of each joint 10', 10 "of the wristband 20', 20" in the above-mentioned prior art can only be made wider due to technical limitations, so the wristband 20' formed by the joints 10' and 10" and 20″ can only be used for men’s watches

[0013] Finally, the watch straps 20' and 20" of the above-mentioned prior art are relatively expensive and easily deformed after a tensile test
