Description

Technical Field

[0001] The utility model relates to the technical field of head tube lighting, in particular to a lighting device embedded in a head tube. Background Art

[0002] A bicycle, also known as a pedal bike or a cycle, is usually a small two-wheeled land vehicle. After a person rides on the bike, it uses the pedals as power and is an environmentally friendly means of transportation. When actually using a bicycle, a lighting device needs to be installed in the head tube above the front wheel axle of the bicycle, so as to facilitate the user to ride at night.

[0003] Chinese Patent with Publication No. CN212373566U discloses a bicycle lamp bracket. The utility model relates to a bicycle lamp bracket, including a bracket body, and the bracket body is provided with a fixing strip and a fixing shaft; the fixing strip is arranged above or below the fixing shaft, and the fixing strip bends towards the fixing shaft to cooperate with the bracket body to form a binding sleeve structure; a locking nut is arranged on the fixing shaft, and a through groove for the fixing strip to pass through is formed between the fixing shaft and the locking nut. After the fixing strip bends, it extends into the through groove. Thread structures that match each other are respectively arranged on the upper surface of the fixing strip and the locking nut, so that the fixing strip can move forward or backward along the through groove as the locking nut rotates. The utility model can be installed on a bicycle firmly enough, and can adjust the angle, which is convenient for disassembling and assembling the lamp. Compared with the existing lamp brackets, it has better stability, better flexibility, and stronger disassembly and assembly convenience.

[0004] However, in the above device, thread structures that match each other are respectively arranged on the upper surface of the fixing strip and the locking nut, so that the fixing strip can move forward or backward along the through groove as the locking nut rotates. However, in actual installation, the outer shell of the lighting device is mostly made of plastic, while the head tube of a bicycle is mostly made of metal. Therefore, when using threaded connection, the thread penetrates into the interior of the plastic product. Since the plastic product has a relatively soft texture, it is very easy to produce a thread slipping phenomenon.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0006] The technical problem to be solved by the present utility model is to overcome the problem that in the prior art, the outer shell of the existing lighting device is mostly made of plastic, while the head tube of a bicycle is mostly made of metal.
