Detailed Description

In order to explain the technical contents, structural features, and effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1 to 3, the connecting structure of a bicycle kettle fixing seat provided by the utility model is suitable for connecting a kettle support, the kettle fixing seat 1 comprises a metal embedded part 2, the metal embedded part 2 is embedded in a frame 3 and is fixedly connected with the frame 3, a slotted hole 21 is arranged on the metal embedded part 2, a connecting thread is arranged in the slotted hole 21, and the top opening of the slotted hole 21 faces the outside of the frame 3.

As shown in fig. 1 to 3, the metal embedded part 2 includes a cone portion 22 embedded in the frame 3, the cone portion 22 is of a cone structure, the cone portion 22 further protrudes outward with a step portion 23, and the slot 21 penetrates through the step portion 23 and extends into the cone portion 22. The step portion 23 protrudes out of the frame 3, the frame 3 is of a hollow structure, the upper portion of the cone portion 22 is embedded in the thickness area of the frame 3, and the lower portion of the cone portion 22 extends into the frame 3, namely the lower portion of the cone portion 22 extends into the hollow inner cavity of the frame 3. The taper part of the metal embedded part is set to be tapered, so that the contact area of the metal embedded part and the frame is larger, the connection is firmer, and the height of the taper part can be determined according to the length of the required connecting thread.

As shown in fig. 3, the edge of the top surface of the pyramid part 22 is an oval structure formed by alternately connecting two circular arcs and two straight edges, which can make the top of the pyramid part more fit the surface of the frame and save more materials.

Specifically, the connecting threads are M5 threads.

In the embodiment of the utility model, the frame is of a carbon fiber composite structure, the metal embedded part is embedded in the carbon fiber yarn and is placed into the mold together with the carbon fiber yarn for molding, so that the metal embedded part and the carbon fiber yarn are integrated, and the connection strength is better.

In the embodiment of the utility model, the metal embedded part is processed by forging process, as shown in fig. 4, before being connected with the frame, the thickness of the step part 23 of the metal embedded part 2 is thicker and 2mm, because the step part 23 is also used for positioning in the forging process, after the metal embedded part 2 is embedded in the frame of the carbon fiber composite material bicycle, a part of the thickness of the step part 23 is ground by milling process, and the thickness of the rest step part 23 is 1 mm.

Compared with the prior art, the kettle fixing seat comprises the metal embedded part, the metal embedded part is embedded in the carbon fiber composite structure frame and is fixedly connected with the carbon fiber composite structure frame, the connection mode is firmer, and can bear larger force, experimental data show that the kettle fixing seat of the connection structure is still not damaged when bearing 25.8 N.m, the strength is very high, and the kettle fixing seat can bear heavier objects.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the present invention, which is therefore intended to cover all equivalent changes and modifications within the scope of the present invention.
