Description

Improved integrated shoulder seat structure

The present invention relates to a shoulder seat structure, and in particular to an improved bicycle shoulder seat structure.

Press, a bicycle front fork includes a shoulder frame, a hollow standpipe and two front fork tubes. The shoulder frame is mostly made by hot forging, so it is often a solid structure. When the shoulder frame is to be connected with the hollow standpipe and the two front fork tubes, When the front tube is combined, a standpipe assembly hole and two front fork tube assembly holes must be machined on the shoulder frame, and then the hollow standpipe is assembled to the standpipe assembly hole by screw locking or welding, and the The two front fork tube sets are arranged in the two front fork tube set holes.

However, since the shoulder frame and the hollow riser are two independent components, the two are formed by screw locking or welding, which is not only cumbersome and time-consuming, but also increases the manufacturing cost, is not economical, and is heavy in weight. The shortcomings of poor structural strength and the need for polishing and other processing after welding. The welding time plus the processing time make the assembly time-consuming and lengthy. If the welding joint cannot be processed perfectly, it must be treated with a protective Covering it with a sleeve will virtually increase component costs and assembly time.

In view of the above-mentioned shortcomings of conventional bicycle front forks, the inventor came up with the idea of creation, and after many discussions and sample tests, as well as many corrections and improvements, he came up with the present invention.

The present invention provides an improved integrated shoulder seat structure, which includes: a shoulder frame, a bearing portion is provided in the middle, two shoulder portions extend from both sides of the bearing portion and two connecting portions are formed, and an upward recess is formed between the two connecting portions. a recessed portion; and a hollow vertical pipe, which is integrally extended upward from the supporting portion. The hollow vertical pipe has a first end connected to the supporting portion and a second end opposite to the first end. The hollow standpipe includes a lower hollow standpipe and an upper hollow standpipe. The lower hollow standpipe is connected to the bearing portion. The upper hollow standpipe is connected to the lower hollow standpipe. The interior of the lower hollow standpipe is composed of the The first end is provided with a lower hollow hole extending in the direction of the second end, and the lower hollow hole penetrates the bearing portion. The upper hollow vertical pipe is provided with an upper hollow hole extending in the direction of the first end from the second end. A reinforcing portion is formed between the lower hollow hole and the upper hollow hole. The lower hollow hole is provided with a first open end and a first inner end opposite to each other. The first open end has a first inner diameter. The first The inner end has a second inner diameter, and the first inner diameter is equal to or larger than the second inner diameter. The upper hollow hole is provided with an opposite second open end and a second inner end, and the second open end has a The third inner diameter, the second inner end has a fourth inner diameter, and the third inner diameter is equal to or larger than the fourth inner diameter.

The main purpose of the structural improvement of the integrated shoulder seat of the present invention is to configure the shoulder frame and the hollow standpipe into an integrated shoulder seat, thereby eliminating the need for welding the hollow standpipe and the shoulder frame and the subsequent polishing process. , the Bida process is simple and fast, saves time and labor, reduces manufacturing costs, is economical, is light in weight, and has good structural strength.
