Description

Technical Field

[0001] The utility model relates to the technical field of watch wristbands, in particular to a watch wristband structure. Background Art

[0002] In the development history of watch straps, many different designs and materials have emerged. Early watch straps were usually made of leather or metal, which are prone to wear or deformation after long-term use. With the advancement of technology, people began to explore new materials and designs to provide more comfortable and durable watch straps. With the continuous development of watch manufacturing technology, some watch straps began to adopt a more convenient quick-release design.

[0003] Upon further search, a Chinese patent with authorization announcement number CN219438367U is found, which is a conveniently detachable wrist jewelry strap, including a watch body, sleeve grooves installed at both sides of the watch body, a first threaded ring is provided on the outer side of the vertical rod shaft, and the left and right sides of the watch body are respectively movably installed with corresponding sub-straps and mother straps through U-shaped sleeve shafts, which effectively solves the problem that a connection device between the existing watch strap and the main body is provided, which is to tighten the watch strap and the watch body through a reset spring structure, but the spring has the defect of reduced elasticity after long-term use, resulting in looseness between the springs.

[0004] According to the description in the comparative patent specification, "the insertion rod 19 can be disassembled by rotating the second right angle opening 21 through a fingernail or other right angle structure, and the fixing effect of the insertion rod 19 can further improve the degree of disassembly of the mother belt 15 and the sub-belt 13" and the drawings of the comparative patent specification Figure 4 It can be seen that the insertion rod 19 and the expansion nut tube 17 are threadedly connected, but the expansion nut tube 17 is arranged on the inner wall of the U-shaped sleeve 8 away from the insertion rod 19, that is, when the insertion rod 19 is inserted into the U-shaped sleeve 8 and connected with the expansion nut tube 17, it is easy to be offset, resulting in the problem of connection failure. In view of this, we propose a watch wristband structure. Utility Model Content

[0015] 1. The utility model provides an insertion rod, a screw column, and a connecting ear, and bends the sub-band and the mother belt. One of the connecting ears is first put on the screw column, and then the other connecting ear is inserted into the outside of the screw column. In this way, the sub-band and the mother belt are initially fixed to the watch body. Then the insertion rod is inserted from the installation groove, and the insertion rod gradually reaches the first screw column. At this time, the flat head nut is rotated, and the insertion rod is able to advance in the thread of the first screw column. The engagement of the thread makes the insertion rod move more smoothly. Finally, the insertion rod moves into the second screw column and is threadedly connected thereto. At this time, the sub-band and the mother belt will not fall off from the watch body.

[0016] 2. The utility model provides an inner lining layer and anti-skid patterns. The inner lining layer increases the comfort of the user, and the anti-skid patterns facilitate the stability of the watch body when worn, so that the watch will not slide easily on the wrist.
