[0021] As used in the specification and claims, certain terminology is used to refer to certain components. Those of ordinary skill in the art will appreciate that hardware manufacturers can use different names to refer to the same component. The description and claims should not be interpreted to require that a component be called the same thing by the same manufacturer to be considered the same component. As used throughout the specification and claims, "comprising" is to be interpreted as "including but not limited to." "Approximately" refers to within an acceptable error range for the corresponding function, which will be understood by one of ordinary skill in the art.

[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "horizontal", and the like refer to the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be understood as a limitation on the present application.

[0023] ​In this application, unless specifically defined otherwise, the terms "mounting", "connected", "connection", "fixed", and the like, should be given a broad interpretation, for example, can be fixed connection, but also can be detachable connection, or integrally connected; can be mechanical connection, but also can be electrical connection; can be directly connected, but also through the intermediate medium indirectly connected, can be two elements inside the communication. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0024] The accompanying drawings are the best embodiment of the training bicycle handlebar head connecting structure, and the application will be further described in detail below in conjunction with the drawings.

[0025] A training bicycle handlebar head connecting structure comprises Figures 1 to 4 As shown, it comprises a handlebar 1 connected with a handle force 101 and a head tube 2.

[0026] The head tube 2 is internally provided with an inner tube 3, and the top of the inner tube 3 is provided with a connecting plate 301 connected with the bottom of the handle force 101.

[0027] The head tube 2 is fixed on the frame, and the inner tube 3 can be slidingly connected with the head tube 2, thereby adjusting the height of the handlebar 1.

[0028] The material hardness of the inner tube 3 is greater than or equal to the hardness of the head tube 2, that is, the two can be made of the same material, and the material hardness of the inner tube 3 can also be greater than the hardness of the head tube 2. For example, the two are made of the same or different types of aluminum alloy, or the head tube 2 is made of aluminum alloy, and the inner tube 3 is made of iron or stainless steel material.

[0029] In order to facilitate installation, the connecting plate 301 and the handle force 101 are detachably connected. In this embodiment, both are provided with threaded holes or through holes, and are fastened and connected by bolts.

[0030] If the inner tube 3 is made of aluminum alloy material, since the connecting part of the connecting plate 301 and the handle force 101 is subjected to a large force during use, long-term use, the characteristics of the aluminum alloy being relatively soft and easy to cut will cause the threaded holes or through holes on the connecting plate 301 to expand, resulting in loose connection and safety hazards.

[0031] In order to solve the above problems, the connecting plate 301 and the handle force 101 are provided with a reinforcing plate 5 made of iron or steel material, which is provided with threaded holes or through holes for facilitating the bolts used to fix the connecting plate 301 and the handle force 101.

[0032] The inner tube 3 is internally provided with a reinforcing rod 4. The reinforcing rod 4 is fixedly connected with the reinforcing plate 5 through a connecting bolt 6. Further, the top surface of the reinforcing rod 4 is provided with a threaded hole 401, and the mounting surface of the force 101 is provided with a waist-shaped hole 102. The end of the connecting bolt 6 is threadedly connected with the threaded hole 401 through the waist-shaped hole 102.

[0033] The hardness of the material of the reinforcing rod 4 is greater than the hardness of the material of the inner tube 3. In the embodiment, the inner tube 3 is made of aluminum alloy, and the reinforcing rod 4 is made of iron or steel material. With this arrangement, the safety in use can be improved under the premise of reducing the cost and the weight of the handlebar head. Even if the inner tube 3 is cracked during the fitness exercise, it will not be bent and deformed under the support of the reinforcing rod 4, and will not cause harm to the exerciser.

[0034] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments. Various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
