[0023] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0024] refer to Figures 1 to 6

[0025] A webbing in-mold injection molding connecting buckle structure comprises a webbing 1, both ends of the webbing are provided with fasteners 2 connected and molded into one piece with the webbing by in-mold injection molding, the fastener is provided with a connecting hole 21 which can be elastically deformed and used to connect with a connecting hook, the connecting hole can connect various types of connecting hooks, and then a badge, work badge, certificate card holder, etc. can be hung on the hook. Connecting the webbing and the fastener by injection molding to form a whole helps to reduce the installation process between the webbing and the fastener, improve the production efficiency of the connecting buckle, and ensure the production quality.

[0026] In this embodiment, the connecting hole includes a vertical hole 211 extending upward from the bottom surface of the fastener into the fastener, and a avoidance cavity 212 with a width or diameter greater than the diameter of the vertical hole is provided at the top of the vertical hole in the fastener, and vertical grooves 213 are horizontally opened on both side walls of the vertical hole, so that the connecting hole has the function of elastic deformation, which facilitates the T-shaped column on the connecting hook head to penetrate into the connecting hole and hang on the connecting hole.

[0027] In this embodiment, the top of the vertical groove and one side close to the vertical hole is communicated with the avoidance cavity, so as to better realize elastic deformation.

[0028] In this embodiment, the front and rear sides of the avoidance cavity both longitudinally penetrate the fastener to form a through hole, which helps to simplify the production process and reduce the difficulty of producing the avoidance cavity.

[0029] In this embodiment, the fastener is made of engineering plastic material, which helps the connecting hole to have the function of elastic deformation.

[0030] In this embodiment, the connecting hook head is provided with a T-shaped column 3 for cooperating with the connecting hole and the end of which extends into the avoidance cavity. The fastener is connected to the connecting hook head by cooperating with the connecting hole.

[0031] In this embodiment, in order to better connect the T-shaped column with the connecting hole, the end of the T-shaped column is provided with a conical surface 31, and the side wall of the vertical hole is provided with a conical surface 214. This structure helps the T-shaped column to better pass through the vertical hole and extend into the avoidance cavity, and the end of the T-shaped column is limited in the avoidance cavity to achieve the connection between the connecting hook and the fastener.

[0032] In this embodiment, the connecting hook head is a self-locking buckle 4, a clip 5, a red buckle 6 or a hook, and the upper part of the self-locking buckle, clip, red buckle, and hook respectively has a T-shaped column that matches the connecting hole. Or in another embodiment, the connecting hook head can be a clip, a red buckle or a hook installed on a hanging ring 7, and the upper part of the hanging ring has a T-shaped column that matches the connecting hole.

[0033] In this embodiment, the webbing is made of nylon, vinylon, polyester, polypropylene or spandex.

[0034] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0035] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0036] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0037] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
