Description

Technical Field

[0001] This invention relates to a jewelry clasp, and more particularly to a curved tube clasp, belonging to the technical field of jewelry accessories. Background Technology

[0002] Modern consumers have higher demands for the functionality and design of jewelry. Magnetic clasps are easier to operate and come in a variety of shapes, better aligning with current fashion trends. Traditional jewelry clasps (such as hooks, spring clasps, and lobster clasps) require two hands or precise alignment, and the opening and closing process often involves deformation. This is especially cumbersome for consumers when wearing bracelets and necklaces, as it is time-consuming, laborious, and prone to metal fatigue, affecting the lifespan of the clasp and resulting in financial loss. Furthermore, traditional jewelry clasps do not conform well to the body's curves when worn with jewelry chains, affecting wearing comfort. Therefore, developing a jewelry clasp that is easy to operate and improves wearing comfort is essential. Summary of the Invention

[0003] To address the problems and shortcomings of the existing technology, the present invention provides a bent tube buckle, the technical solution of which is as follows: A type of curved tube buckle consists of a buckle body and a pin inserted into the front end of the buckle body. The buckle body has a curved hollow cylindrical structure and a flexible, movable button at the top.

[0004] Optionally, the button has a rocker structure, with the bottom support part movably connected to the bottom of the buckle body cavity via a connecting post. The two ends of the button are a pressing end and a snap-on end, respectively. A spring is provided between the bottom of the pressing end and the bottom of the buckle body cavity, and the snap-on end is engaged with the pin inserted into the buckle body.

[0005] Optionally, the bottom of the inner cavity of the buckle is connected to the connecting post via a radially arranged threading rod, which is used to limit the position of the connecting post.

[0006] Optionally, the bottom of the snap-on end of the button is provided with a downward-protruding chamfer.

[0007] Optionally, the connecting post is disposed in the groove at the bottom of the buckle body cavity.

[0008] Optionally, the front end of the knitting needle has a needle-shaped structure, and its tip is provided with a raised chamfer in the circumferential direction.

[0009] Optionally, the chamfer is a curved chamfer.

[0010] Optionally, a through hole is provided at the bottom of the rear end of the buckle body.

[0011] Optionally, a through hole is provided at the bottom of the rear end of the knitting needle.

[0012] Optionally, the curvature of the back end of the knitting needle matches the curvature of the button body.

[0013] Compared with the existing technology, the technical solution of this invention has the following advantages: the use of a curved cylinder structure combined with a spring locking structure can not only conform to the curve of the human body and improve wearing comfort, but also realize one-handed opening and closing, which is simple, convenient and labor-saving.

[0015] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below. Example 1

[0017] like Figure 1-7 As shown, a curved buckle consists of a buckle body 1 and a pin 4 inserted into the front end of the buckle body 1. The buckle body 1 is a cylindrical, curved, hollow structure with a movable, elastically mounted button 2 at the top. The button 2 is a rocker-type structure. The bottom support is movably connected to the bottom of the inner cavity of the buckle body 1 via a connecting post 6. The two ends of the button 2 are a pressing end and a locking end, respectively. A spring 5 is provided between the bottom of the pressing end and the bottom of the inner cavity of the buckle body 1. The locking end engages with the pin 4 inserted into the buckle body 1. The bottom of the inner cavity of the buckle body 1 is connected to the connecting post 6 via a radially arranged threading rod 7, which is used to limit the movement of the connecting post 6. Example 2

[0018] When locking, align the buckle body 1 and the pin 4, insert the pin 4 into the opening at the front end of the buckle body 1, and the circumferential chamfered protrusion at the tip of the pin 4 contacts the downward chamfered protrusion at the snap-fit ​​end of the button 2. As the pin 4 is inserted into the buckle body 1, due to the rocker mechanism of the button 2, the snap-fit ​​end of the button 2 is lifted upward under the interaction force, and the pressing end is lowered downward, so that the spring 5 between the pressing end and the bottom of the inner cavity of the buckle body 1 is in a compressed state. When the circumferential chamfered protrusion at the tip of the pin 4 passes the downward chamfered protrusion at the snap-fit ​​end of the button 2, the snap-fit ​​end is no longer under force, and the spring 5 between the pressing end and the bottom of the inner cavity of the buckle body 1 returns to an extended state. Under the action of the spring 5, the pressing end is lifted upward, and the snap-fit ​​end of the button 2 is lowered downward. Its downward chamfered protrusion engages in the groove formed by the circumferential chamfered protrusion at the tip of the pin 4 and the rear end, so that it axially limits the striker 4 and achieves the locking state. Example 3

[0019] When opening, press the pressing end of the button 2 on the top of the buckle body 1, so that the downward protruding chamfer of the buckle end falls down. At this time, the buckle end of the button 2 is lifted up, so that the downward protruding chamfer of the buckle end disengages from the circumferential protruding chamfer of the tip of the pin 4, thereby releasing the axial limit on the striker 4, and pulling the striker 4 backward to achieve the open state. Example 4

[0020] The downward-protruding chamfer at the bottom of the snap-on end of the button 2 and the circumferential chamfer at the tip of the needle 4 are both arc-shaped chamfers. Example 5

[0021] Both the rear end of the buckle body 1 and the bottom of the rear end of the needle 4 are provided with through holes for connecting to the wrist strap.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
