[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0029] See Figures 1 to 3 As shown, a one-piece molded denim buttonless button includes a pin holder 1 and a one-piece molded button body 2. In this embodiment, the button body is integrally die-cast, and the pin holder is a conventional structure of the prior art, which is simply applied. In this embodiment, the one-piece molding means that the traditional split button body is processed into one piece, which solves the problems of split button bodies on the market being easy to fall off and inconvenient to use. Moreover, the one-piece molded button body is more convenient to use and has a practical structure.

[0030] Furthermore, the buckle body is provided with an upper circular hole 3 and a lower frustum-shaped through hole 4 that are connected to each other, and the small diameter end of the lower frustum-shaped through hole is close to the needle seat; the inner diameter of the upper circular hole and the inner diameter of the large diameter end of the lower frustum-shaped through hole are the same.

[0031] In this embodiment, a hollow limiting pin 5, a spring 6, and a limiting washer 7 are also provided. The side wall of the hollow limiting pin has several circular holes 8 communicating with the inner cavity of the hollow limiting pin. Steel balls 9 are placed inside the circular holes. The spring mainly provides a downward force to keep the hollow limiting pin within the lower circular through hole, allowing the steel balls to firmly press against the outer wall of the needle holder and the inner wall of the lower frustum-shaped through hole, preventing the needle from loosening or falling off. The limiting washer is used to limit the upper end of the spring. An annular groove 12 is provided on the outer wall of the needle tip of the needle holder; the steel balls are inserted into the annular groove for limitation.

[0032] During assembly, the hollow limiting pin is positioned within the lower frustum-shaped through hole, the limiting washer is positioned within the upper circular hole, the spring is positioned between the hollow limiting pin and the limiting washer, and the outer surface of the steel ball abuts against the inner wall of the lower frustum-shaped through hole. The needle body of the needle holder is inserted through the small-diameter end of the lower frustum-shaped through hole and engages with the hollow limiting pin. The steel ball presses against the outer wall of the needle holder and the inner wall of the lower circular through hole to position the needle holder. In this embodiment, the overall structure is simple, which helps improve assembly efficiency, reduces processing difficulty, and ensures the stability and reliability of the needle holder connection, preventing loosening or detachment.

[0033] In this embodiment, the sidewall thickness of the lower frustum-shaped through hole is less than the diameter of the steel ball. This ensures the effectiveness and reliability of the pressure between the steel ball and the needle body of the needle holder.

[0034] In this embodiment, an annular groove 10 is provided on the inner wall of the upper circular hole; the edge of the limiting washer is inserted into the annular groove for limitation. During processing, the inner diameter of the annular groove is larger than the outer diameter of the limiting washer, and the outer diameter of the limiting washer is larger than the inner diameter of the upper circular hole. During installation, one end of the limiting washer is first inserted into one end of the annular groove, and after the limiting washer is fully inserted into the upper circular hole, the position of the limiting washer is adjusted to complete the installation of the limiting washer in the annular groove.

[0035] In practical applications, the hollow limiting pin includes an integrally formed upper cylinder 51 and a lower cylinder 52. The diameter of the upper cylinder is smaller than that of the lower cylinder, and the outer diameter of the upper cylinder matches the inner diameter of the limiting washer. The circular hole is located on the side wall of the lower cylinder. The spring is sleeved on the outside of the upper cylinder, and its two ends press against the top surface of the lower cylinder and the bottom surface of the limiting washer, respectively. During assembly, the top end of the upper cylinder can be positioned inside the limiting washer, while also ensuring that the limiting washer is stable and will not loosen or fall out of the annular groove.

[0036] Meanwhile, the needle length of the needle holder is greater than the height of the hollow limiting pin, and the diameter of the needle body matches the inner diameter of the hollow limiting pin. The needle insertion depth of the needle holder is achieved by the steel ball; that is, the steel ball can press against the outer wall of the needle holder to complete the installation and positioning of the needle holder. Furthermore, to enhance the decorative effect, the top surface of the buckle body is provided with a decorative pull tab 11, the bottom end of which is locked in place at the upper part of the inner cavity of the hollow limiting pin. The diameter of the decorative pull tab is greater than the diameter of the upper circular hole.

[0037] In this embodiment, the shape of the buckle is flower-shaped.

[0038] This utility model has positive effects: The structure of this utility model is reasonably designed, including an integrally formed buckle body, which is combined with a hollow limiting pin, a spring and a steel ball. When the needle body is inserted into the needle holder, under the action of the spring and the steel ball, the steel ball is pressed and clamped against the outer wall of the needle body through the inner wall of the lower frustum-shaped through hole. This can clamp and position the needle body, improve the convenience and stability of the connection, reduce the use of fasteners, help reduce the cost of manual assembly, improve the efficiency of assembly, and solve the technical shortcomings of the traditional split buckle structure, which is easy to fall off and is troublesome to use. It has strong applicability. Example
