Description

Improved Structure Bicycle Single Flywheel

technical field

The utility model relates to a single flywheel in a bicycle in the field of trackless land vehicles, in particular to a bicycle single flywheel with an improved structure. It utilizes the inter-connected teeth to achieve the effect of convenient and quick disassembly, and becomes a very practical and progressive new design, which is suitable for wide application in the industry.

Background technique

The structure of the current general existing bicycle single freewheel is shown in Fig. 1, which is an exploded perspective view of the Taiwan patent announcement No. 306412 "single-speed ratchet hub" (see Annex 1 for details, namely the Taiwan patent announcement No. 306412 " Single-speed ratchet hub "announcement text), its structure mainly comprises a hub body (20), and one end of the hub body (20) is embedded with a sleeve (30), and a ratchet wheel is arranged in the sleeve (30) Seat (40), utilize at last to be provided with a shaft rod (50) to be penetrated and form the fixed structure, thus reach the flywheel function with unidirectional rotation. However, as we all know, after the ratchet seat (40) is placed in the sleeve (30), because it cooperates with the rotation of the toothed plate (90) to achieve the effect of interlocking the hub body (20), so the The tightness in (30) is also easily affected by the user's long-term use to form a semi-clamped state. Therefore, if any internal parts are damaged and need to be replaced, the ratchet seat ( 40) This action is quite cumbersome, and in order to make it more smooth in the dismantling process, the general industry will improve the ratchet seat (40) to varying degrees, so as to achieve the effect of smooth dismantling.

Please refer to Fig. 2 and shown in Fig. 3 for the bicycle single flywheel of this existing conventional improved structure. And the end edge of a tool handle (12) is provided with convex parts (121), (121 ') relative to the concave parts (11), (11 '), so as to achieve the effect of smooth opening, but this kind of existing The conventional bicycle single flywheel with improved structure still has disadvantages in use, and the defects in its use are described as follows:

1. First of all, due to the limited contact area of the concave and convex structure of the conventional bicycle single flywheel with improved structure, it is easy to cause the user to slip when operating the tool handle and come out during disassembly. Dangerous action, so not safe.

2. Moreover, the conventional bicycle single flywheel with an improved structure is easy to cause the wear and tear of the concave and convex parts during disassembly because the concave and convex parts bear all the weight. , and after a long time of use, the concave and convex parts can no longer be closely connected, which causes inconvenience in maintenance.

The above is the single flywheel structure of the existing general improved structure of the bicycle, because this structure will not only cause inconvenience to the user, but also cause safety concerns, so overall it is quite impractical. This shows that above-mentioned existing single flywheel of bicycle still has many defectives, and Cheng waits to be further improved.

In view of the defects of the above-mentioned existing bicycle single flywheel, the designer actively researches and innovates based on the rich practical experience and professional knowledge engaged in the design and manufacture of such products for many years, in order to create a new type of bicycle single flywheel with improved structure , can improve the existing conventional bicycle single flywheel structure on the general market, making it more practical. Through continuous research, design, and after repeated trial samples and improvements, the utility model with practical value is finally created.
