Description

Technical Field

[0001] The utility model relates to a 3D printed titanium alloy internal wiring riser, belonging to the technical field of titanium alloy product manufacturing. Background Art

[0002] Since its birth, bicycles have been a popular and convenient means of transportation. In recent years, the theme of low-carbon and environmentally friendly life has been deeply rooted in people's hearts, and bicycles have become an indispensable part of almost every household. In particular, titanium alloy bicycles have become a rising star in the domestic bicycle industry under the pursuit and publicity of high-end players. As a high-end product in the bicycle industry, the popularity of titanium alloy bicycles has remained high. However, consumers are no longer only pursuing bicycle frames for titanium alloys, but also their pursuit of full titanium alloy vehicles is also increasing. From frames to spare parts, titanium alloys are needed.

[0003] Although titanium alloy bicycles and bicycle accessories are highly sought after and favored by people, the production of titanium alloy bicycle frames and bicycle accessories is not as simple as that of traditional material bicycle frames, because titanium alloy materials have high hardness, and the current existing processing technology is difficult to complete a lighter and more beautiful cavity structure under the premise of ensuring the strength of the parts. However, in the high-end bicycle market, titanium alloy bicycles with full internal wiring are more likely to be favored by people. Full internal wiring of bicycles is inseparable from the riser with full internal wiring, but the current processing technology is difficult to achieve an integrated riser with internal wiring. 3D printed titanium alloy internal wiring riser can perfectly solve this problem. Therefore, a 3D printed titanium alloy internal wiring riser was born. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] A 3D printed titanium alloy internal wiring riser comprises a riser body 1, a plug 2, a washer 1 3, a washer 2 4, a bottom cover 5, a clamp 6, and a head pipe 7; the clamp 6 is installed in the head pipe 7, and the front fork riser is inserted into the clamp 6, the bottom cover 5 is installed in the clamp 6 through a tenon, the washer 2 4 and the washer 1 3 are connected to the bottom cover 5, the plug 2 is installed in the riser body 1, and inserted into the front fork riser, and is locked by the top screw at the rear end of the riser body 1, and the riser body 1 and the front fork riser are locked by bolts through the screw holes reserved in the riser body 1.

[0018] The riser body 1 is connected to the washer 1 3 and the washer 2 4 by means of tenons. The washer 1 3, the washer 2 4 and the riser body 1 are all provided with wiring channels, which can ensure the smoothness of the wiring and reduce the wear of the wire tube. The thickness and quantity of the washers can be freely matched according to needs.

[0019] The washer 2 4 and washer 1 3 are connected to the bottom cover 5 through a tenon, and a wiring channel is reserved in the bottom cover 5. The clamp ring 6 is installed between the head tube bowl assembly and the bottom cover 5, and the clamp ring 6 has a wiring groove to ensure that the wire tube passes through the head tube without affecting the steering of the bicycle, and the clamp ring is mostly hollowed out to greatly reduce the weight of the structure.

[0020] The block 2 is installed inside the seat tube body 1 and tightened by a jackscrew. Both the block 2 and the seat tube body 1 are designed to prevent displacement, which can ensure the firmness of the installation of the front fork stem and the seat tube.
