Description

Technical Field

[0001] This utility model relates to the field of jewelry connector technology, specifically a bracelet connection structure. Background Technology

[0002] Bracelets, as a common type of jewelry, are loved by many. There are many types of bracelets, including wide bracelets, narrow bracelets, and beaded bracelets. Among them, wide bracelets and beaded bracelets mostly use a buckle connection similar to a watch strap. Their wearing length is not adjustable, which cannot adapt to different users' wrist sizes. Their poor fit is not conducive to product sales and mass production. Generally, custom-made bracelets are required to ensure optimal wearing comfort. However, custom-made bracelets are expensive, and if the wearer's wrist size changes later, the bracelet may become too tight or fall off, affecting the normal use and wearing effect of the bracelet. Therefore, they have certain shortcomings. Utility Model Content

[0003] The purpose of this utility model is to provide a bracelet connection structure to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bracelet connection structure, comprising a first column and a second column, both of which are hollow. A threaded hole is formed at one end of the first column, and a first chain groove communicating with the threaded hole is formed at the threaded hole location. A chain buckle is fixedly installed in the first chain groove. The chain buckle has an arc-shaped cross-section, one end of which is fixed to the first column, and the other end is not connected to the first column. The chain buckle is made of an elastic metal component. A threaded connecting post adapted to the threaded hole is fixedly connected to one end of the second column, and the threaded connecting post is threadedly sleeved within the threaded hole. The connecting threaded connecting post has a second chain groove at one end and also includes an extension chain. One link of the extension chain is fastened to a chain buckle. The second post has through holes at the center of the end face away from the threaded connecting post and the first post has through holes at the center of the end face away from the threaded hole. One end of the extension chain passes through the through hole of the second post. The connecting post also includes a bracelet connecting post that slides through the through hole of the first post. The bracelet connecting post has a stop at one end inside the first post to prevent the bracelet connecting post from detaching from the first post while ensuring that the first post can rotate. The stop of the bracelet connecting post is a circular boss with a diameter larger than the diameter of the through hole. The boss is integrally formed with the bracelet connecting post.

[0005] Preferably, the inner wall of the through hole is smooth and rounded to avoid wear on the bracelet connecting post and extension chain, extend the service life of the bracelet connecting structure, and ensure that each component can still maintain good sliding and rotation performance during long-term use.

[0006] Preferably, the outer surfaces of both the first and second pillars are provided with decorative textures or patterns to enhance the aesthetics of the bracelet, so that the bracelet not only has practical functions, but also meets the user's needs for the aesthetics of the jewelry, thereby enhancing the product's appeal.

[0007] Preferably, the first column and the second column have the same external dimensions. Both the first column and the second column are frustums with gradually changing diameters. Their outer diameters and heights are the same, and their through holes are coaxially arranged.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This utility model has a simple and ingenious structure. Users can fix different links on the extension chain according to their needs to adjust the length of the bracelet. Users can adjust it according to their own wrist size. The operation is simple and convenient, and the connection is stable and reliable. It will not loosen or fall off during wear, which improves the comfort of wearing the bracelet and the user experience. Since the device can adjust the length of the bracelet, it can be adapted to consumers with different wrist sizes, which is conducive to the mass production and sales of the product and promotes its use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 6 This utility model provides a technical solution: a bracelet connection structure, including a first column 1 and a second column 2. Both the first column 1 and the second column 2 have hollow interiors for placing an extension chain 3. A threaded hole 101 is formed at one end of the first column 1. A first chain groove 103 communicating with the threaded hole 101 is formed at the same location on the first column 1. A chain buckle 102 is fixedly installed in the first chain groove 103. The chain buckle 102 has an arc-shaped cross-section. One end of the chain buckle 102 is fixed to the first column 1, while the other end is not connected to the first column 1. The chain buckle 102 is made of an elastic metal component. A threaded connecting post 201 adapted to the threaded hole 101 is fixedly connected to one end of the second column 2. The threaded connecting post 201 is threaded into the threaded hole 101. A second chain is formed at the end of the second column 2 connected to the threaded connecting post 201. The groove 202 also includes an extension chain 3, one link of which is fastened to the buckle 102. Through holes 203 are provided at the center of the end face of the second column 2 away from the threaded connecting column 201 and the end face of the first column 1 away from the threaded hole 101. One end of the extension chain 3 passes through the through hole 203 of the second column 2. It also includes a bracelet connecting column 4, which slides through the through hole 203 of the first column 1. A stop is provided at the end of the bracelet connecting column 4 located inside the first column 1 to prevent the bracelet connecting column 4 from detaching from the first column 1 while ensuring that the first column 1 can rotate. The first column 1 and the second column 2 have identical external dimensions. In actual use, one end of the bracelet connecting column 4 is connected to one end of the bracelet body by welding or other fixing methods, and one end of the extension chain 3 is fixedly connected to the other end of the bracelet body. When adjusting the bracelet's length, the user can first untie the knot of extension chain 3 from clasp 102, and then re-clasp the other knots of extension chain 3 onto clasp 102 as needed to complete the bracelet length adjustment. Users can adjust the length according to their wrist size; the operation is simple and convenient, and the connection is stable and reliable, preventing loosening or detachment during wear, thus improving the bracelet's comfort and user experience.

[0019] Furthermore, the inner wall of the through hole 203 is smooth and rounded to avoid wear on the bracelet connecting post 4 and the extension chain 3, extend the service life of the bracelet connection structure, and ensure that each component can still maintain good sliding and rotation performance during long-term use.

[0020] Furthermore, the outer surfaces of both the first pillar 1 and the second pillar 2 are decorated with decorative textures or patterns to enhance the aesthetics of the bracelet, making it not only functional but also satisfying users' aesthetic needs and increasing the product's appeal.

[0021] Furthermore, the first column 1 and the second column 2 have the same external dimensions. Both the first column 1 and the second column 2 are frustums with gradually changing diameters. Their outer diameters and heights are the same, and their through holes 203 are coaxially arranged.
