Description

Technical Field

[0001] The utility model relates to a webbing connection buckle structure. Background Technology

[0002] Lanyards are often used to hang badges, work certificates, etc., and the webbing fasteners used to connect badges or work certificates on the lanyards are usually composed of a fastener body and a connecting hook. During the manufacturing process of the webbing fastener, after the connecting hook is manufactured, the fastener body and the connecting hook are connected together through die-casting and other processing procedures, such as the connecting buckle disclosed in CN308537651S. This virtually increases the difficulty of manufacturing the webbing fasteners, and the production efficiency is low. In addition, the webbing fasteners are generally metal parts, which are more expensive. Contents of utility model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the above features and advantages of the present utility model more understandable, the following specific embodiments are given in conjunction with the accompanying drawings and described in detail as follows, but the present utility model is not limited thereto.

[0021] Reference Figures 1 to 5

[0022] A webbing connection buckle structure includes a fastener body 1 made of plastic. For example, the fastener body is made of engineering plastic material, which helps the connection hole have the function of elastic deformation. A connection hole 10 is provided on the fastener body, which can be elastically deformed and into which a connection part 20 of a connection hook head 2 is inserted for hanging, so that the connection part of the connection hook head can be directly inserted into the connection hole, and the connection between the two can be achieved by pressing manually once.

[0023] In this embodiment, the connection hole includes a vertical hole 11 extending from the bottom surface of the fastener body into the fastener body. An avoidance cavity 12 with a width or diameter larger than the diameter of the vertical hole is provided at the top of the vertical hole in the fastener body. Vertical grooves 13 are transversely opened on both side walls of the vertical hole, so that the connection hole has the function of elastic deformation, which is convenient for the connection part on the connection hook head to be inserted into the connection hole by elastic deformation of the connection hole and complete the hanging, so that the connection hook head is hung on the connection hole.

[0024] In this embodiment, the top of the vertical groove and the side close to the vertical hole are connected to the avoidance cavity, so that the connecting hole can better achieve elastic deformation.

[0025] In this embodiment, the upper end of the connecting part of the connecting hook head has a convex part 21 that can elastically deform the connecting hole and is limited by the bottom surface of the avoidance cavity after extending into the avoidance cavity. Specifically, the connecting part can be a T-shaped column.

[0026] In this embodiment, in order to better connect the T-shaped column with the connecting hole, a conical surface 14 is provided on the side wall of the vertical hole, and a conical surface 22 is provided on the side wall of the convex part. This structure helps the convex part of the T-shaped column better pass through the vertical hole and extend into the avoidance cavity. After the convex part of the T-shaped column extends into the avoidance cavity, the connecting hole elastically resets, so that the convex part is limited by the bottom surface of the avoidance cavity, realizing that the connecting hook head is suspended on the fastener body.

[0027] In this embodiment, the front and rear sides of the avoidance cavity longitudinally penetrate the fastener body and form through holes, which helps to simplify the production process and reduce the production difficulty of the avoidance cavity.

[0028] In this embodiment, the fastener body can be integrally injection-molded with the webbing 7 by in-mold injection. Or two horizontally arranged grooves are vertically opened on the upper part of the fastener body and are arranged in a staggered manner to facilitate the webbing to form a V shape, such as the horizontally arranged groove structure disclosed in the webbing connection buckle structure of patent CN202321778185.X.

[0029] In this embodiment, the outer shape of the fastener body can be in polygonal shapes such as rectangular, V-shaped, W-shaped, etc., which helps to improve the aesthetics.

[0030] In this embodiment, the connecting hook head is a self-locking buckle 3, a clip 4, a Zhudan buckle 5 or a hook. The upper parts of the self-locking buckle, the clip, the Zhudan buckle and the hook respectively have a T-shaped column (connecting part) that matches the connecting hole. Or in another embodiment, the connecting hook head can be a clip, a Zhudan buckle or a hook installed on the hanging ring 6, and the upper part of the hanging ring has a T-shaped column that matches the connecting hole.

[0031] If the present invention discloses or involves mutually fixedly connected parts or structural parts, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, using bolts or screws), or it can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutually fixed connection can also be replaced by an integral structure (for example, manufactured by integral forming using casting technology) (except for obvious cases where integral forming technology cannot be used).

[0032] In addition, the terms used to represent the positional relationship or shape in any of the technical solutions disclosed in the present invention, unless otherwise stated, include states or shapes that are approximate, similar or close to it.

[0033] Any component provided by the present utility model can either be assembled from multiple individual components or be a single component manufactured by an integral forming process.

[0034] The above are only the preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
