A metal watchband edge banding mechanism

Abstract

The invention discloses a metal watchband edge banding mechanism. The mechanism comprises a plurality of band granules, pin joint parts and watch granules arranged at two sides of the band granules, band granule bores are arranged at two ends of each of the band granules, two counter bores are arranged at the inner side of each of the watch granules, the pin joint parts comprise pins and sleeves, the pins are cylinders, the sleeves are cylinders having a C-shaped cross section, the sleeves interpenetrate in the band granule bores, one ends of the pins are inserted into the counter bores on the watch granules, and the other ends of the pins are inserted into the sleeves. The metal watchband edge banding mechanism has the advantages of beautiful appearance, stable structure, never pin dropping, and repeatable dismounting and mounting.

Description

technical field [0001] The invention relates to an edge sealing mechanism, in particular to an edge sealing mechanism for a metal watchband. Background technique [0002] A watch, also known as a watch, refers to an instrument worn on the wrist for timing and displaying time. As a living product integrating decoration and practicality, it has been liked by many people. Among them, the metal watch strap The watch shows a sense of maturity and stability, and is deeply loved by successful people. The general metal watch strap is made of several hinged joints, and the number can be adjusted according to the thickness of the arm. Therefore, the pivotal parts of the watch band are especially important. The key, and the pivotal parts currently on the market are generally mother-in-law links, toothed branches, hairpins, raw ears and screw ear bars, of which: [0003] The pivot structure of the mother-to-son connection is composed of a needle and a pipe, and there are grooves on the...

AI Technical Summary

Problems solved by technology

[0003] The pivot structure of the mother-to-son connection is composed of a needle and a pipe, and there are grooves on the needle and the pipe. When the two grooves are completely overlapped, the stress generated will fix the needle in the pipe. However, since the through tube is made of non-elastic material, the through needle will damage the groove during insertion into the through tube, which prevents the two from completely overlapping, which reduces the tight fit, and when the two overlap, the entire sub The force of the female channel is only on the groove, so it is easy to cause the strap to loosen or the needle to drop

[0004] The articulated structure of the toothed stem is a pin with a diameter larger than the watch grain hole. The pivotal connection is realized by forcibly inserting the toothed stick into the watch grain hole. However, the materials of some metal strap edge banding mechanisms are high hardness and low toughness. If the assembly is forced, it will cause the assembly to expand and cause the strap to crack or break

[0005] Although the hairpin assembly can solve the problem of the cracking of the tooth flower branch, it is easy to scratch the hand during the installation process, and it cannot be disassembled repeatedly, and the needle is easy to drop during use

[0006] The raw lug connection and the screw lug are mainly used in the pivot connection between the strap and the watch buckle, and the strap and the watch case. However, the raw lug has problems such as unstable elasticity and easy to fall off. Although the screw lug can be effectively fixed, the two The ends need to be fastened with flathead or cross-head screws, which greatly affects the appearance, and once the screw teeth are loose, the screws will fall off

[0007] The above-mentioned pivot connection method not only has certain potential safety hazards, but also requires via holes on the watch grain, which makes the side of the strap look unattractive. To solve the above problems, we provide a safe, beautiful and Edge banding mechanism that can be disassembled repeatedly
