[0025] 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.

[0026] refer to Figures 1 to 6

[0027] A webbing in-mold injection-molded integrated connecting buckle comprises a webbing 10, wherein the webbing is made of nylon, vinylon, polyester, polypropylene or spandex. The two ends of the webbing are fitted together to form a V-shape between the two ends of the webbing, and a fastener 20 is provided which is connected and molded into one piece with the webbing by in-mold injection molding, that is, the two ends of the webbing are overlapped to form a V-shape and then placed in an injection mold of the fastener, and the fastener is formed by injection molding and connected to the webbing as one piece. The fastener can be made of engineering plastic material, and a connection hole 21 which can be elastically deformed and is used to connect with a connecting hook is provided on the fastener.

[0028] By connecting the webbing and the fastener through injection molding to form a whole, it helps to reduce the installation process between the webbing and the fastener, improve the production efficiency of the connection buckle, and ensure the production quality. Various types of connection hooks can be connected through the connection hole, and then the badge, work card, ID card holder, etc. can be hung on the hook.

[0029] 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.

[0030] In this embodiment, the top of the vertical groove and one side close to the vertical hole is connected to the avoidance cavity, so as to better realize elastic deformation and help the T-shaped column 30 on the connecting hook head to extend into the avoidance cavity.

[0031] 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.

[0032] In this embodiment, the connecting hook head is provided with a T-shaped column 30 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.

[0033] 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 to form a truncated cone, 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. The end of the T-shaped column is limited in the avoidance cavity, realizing the connection between the connecting hook and the fastener, simplifying the connection difficulty of the connecting hook and the fastener, and facilitating installation.

[0034] In this embodiment, the connecting hook head is a self-locking buckle 40, a clip 50, a red buckle 60 or a hook, and the upper part of the self-locking buckle, clip, red buckle, and hook respectively has a T-shaped column matched with 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 70, and the upper part of the hanging ring has a T-shaped column matched with the connecting hole.

[0035] 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).

[0036] 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.

[0037] 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.

[0038] 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.
