New description: [New technical field] This creation is about the structure of bicycle before strengthening. It mainly uses the front fork frame to separate the poles and the vertical pipe on both sides and set the screw lock design. Simplify the manufacturing and assembly difficulty, and at the same time, the fork rods on both sides can be forged and cast, and the reinforcing ribs on the inner side of the ribs can be added to enhance the structural strength. 俾Can solve the existing bicycle welded front fork frame Potential safety concerns. I [Prior Art] Press, the general bicycle in the design of its front fork, please refer to the second and second pictures, usually with a vertical tube (丄) to insert the front handle frame (not shown), and A fork pipe (2) is welded on both sides of the lower part of the vertical pipe (1), and a joint piece (3) is welded on the front side of the lower end of the fork pipe (2), and the groove is preset by the joint piece (3) (4) The wheel axle (6) of the wheel body (5) can be inserted into the wheel body, and the nut (7) can be locked and fixed, that is, the assembly of the front fork frame and the wheel body is completed. In view of this type of front and rear structure, because the vertical pipe and the two sides of the fork pipe are welded and welded, in addition to the appearance of the ugly weld marks, which affects the appearance, it is also more troublesome in the welding operation. Inconvenience, especially the welding quality of the standpipe and the fork pipes on both sides depends on the experience and technology of the construction personnel, which makes it difficult to maintain the stability of the αα quality, and even due to its poor welding quality, the structural strength is weak, and may be When riding a bicycle, it encounters the effect of road surface bounce or other external force, that is, the weld joint is cracked, which affects its overall structural strength, or even breaks and disintegrates. It becomes the safety of the M287280 in its structural design. . Moreover, because the vertical pipe and the two sides of the rod are combined by manual welding, the longitudinal and lateral precision of the combination of the sage and the fork pipe will be difficult to maintain, which leads to more or less existence before the manufacture. The error of the specification even makes the structural safety of the assembled car body worry about the improvement. In the case of the bicycle body type, when the bicycle encounters a road pit or a beating road, the action stress will be transmitted through the wheel body and its wheel to act on the fork tubes and the front side knots. In combination with the film, in this production form, because the general non-professional bicycle will not be placed on the front frame, the stress is directly resisted by the two sides of the tube, but because of its fork system Made of hollow pipe body, its structural strength itself is not very strong, and long-term exposure to such stress will inevitably cause damage to the structure of the pipe, resulting in easy deformation and depression, even called external force. The impact is severely deformed, forming a great safety obstacle on the ride, and the people are cautious. The Wen Wang丨 urgently needs to try to solve it.
