Abstract of Chinese New Model: -_ Make it available on the crank body: Γ = 二 ===: so that it can be used without affecting the strength and rigidity of the crank itself, but can be used to make the entire support The crank achieves weight reduction. 6.

New type description: [Technical field to which the new type belongs] t 创 L 是 是A solid bicycle crank that has been initially formed, and the existing metal processing is consistent; but one is weaving two [prior art] and the high-priced bicycle, the bicycle pedal crank that is commercially available, is very diverse, M278633 • Think carefully about how Increasing the sales force of bicycles in order to increase their sales power ^ Earth-the strength of the pieces, and how to reduce the weight of the bicycle, _ •, can be safer and more comfortable when riding. : Then, in addition to the current best metal materials, manufacturers of various parts of self-propelled bicycles use the current various metal processing methods or casting methods to defend bicycle parts.: For bicycle pedal cranks Under the consideration of light weight, the industry has also developed a variety of handles, and currently there are two types of hollow cranks that are more common;-one is a hollow crank made of multiple sheets, and the other is a more common casting method. Hollow cranks processed, #Hollow cranks formed by the two guard methods have many disadvantages (for example, insufficient strength). The main reason is that the processing steps are too complicated and the processing cost is too high, which affects the positive support crank. The unit price also affects the price of the entire bicycle. [New content] The creator has dreams of: ,, m, shell ^ crank, if you can use a good metal processing method, in fact, as long as the appropriate position of the handle, plus 4 holes, you can also reach the bicycle pedal song Ban Qing Er ==, can even take into account the strength of solid cranks without the flexibility of hollow cranks, so the creator worked hard to develop this work, using many metal processing methods (such as: drilling) to become a porous crank. [Implementation] = Examination diagram; it is a better example of this creation. For example, the first picture is a three-dimensional drawing of the creation. Except for the cross-sectional view of the hole surface, it can be = / _ ⑽. At this hole (20), the third picture is the top view of the creation, the two holes (20) on the handle (10) are still finished, and the fourth picture is the left cross section of M278633, showing the crank (Ίο) There are two blind holes (20) made by metal processing, and there are no holes (20) in the gear shaft hole (30). The fifth picture is the right perspective of the creation. There are two blind holes (20) machined from metal. The sixth picture is the perspective view before the creation of the 'visible crank (10), there are two holes (20). To sum up, this creation is based on the diagram. I would like to list two holes as the representative of the porous holes. In fact, this creation can be used with a variety of metal processing methods, that is, at the appropriate position of the crank without affecting the strength of the crank itself. Countless holes of various sizes can be created to achieve the goal of lightweight cranks. [Schematic description] The first picture is a three-dimensional view of this creation. The second picture is a cross-sectional view of this creation. The third picture is the top view of this creation. The fourth picture is the left section of this creation. _ ^ The five pictures are the right perspective of this creation. The sixth picture is a perspective view before the creation of this book.
