New description: [New technical field] The improvement of the five-way pipe structure of the bicycle body (1) provides dust resistance and waterproofing, strengthens stable support, reduces the complexity of the production of various parts and reduces inventory. A variety of destinations for alternate quantities. [Prior Art] According to the general bicycle body, the children of Oita children, teenagers, adult, men, adult women, etc., can also be distinguished by different purposes such as general, competition, off-road, performance, etc. All the car bodies in the forest are added in a variety of sizes and sizes, and the components used are relatively different. Wherein, the pedals provided in the body of the vehicle are assembled in the shaft end of the five-way socket, and then the chain is assembled by the shaft, and the chain is further determined by the stringer to be different from the rear wheel. The sprocket wheel is chained, so that when the pedal is stepped on the pedal, the sprocket is driven by the sprocket wheel to move forward; and as described above, due to the large number of bicycles, the five-way socket specification in the vehicle body The difference is that the size of the assembled components will be different. Therefore, when the car body derived from different uses and people riding is different, the components are relatively more specifications and stocked. Alternate, as a result, the production cost and management of the industry is a heavy burden, and the assembly is also paying more attention, and these details will cause the trouble of the manufacturer in the assembly, and the entire five-way management The design will also consider whether the shaft will be affected by external dust and moisture, affecting the smoothness of the 4 M295081 to the rotation, and whether the bearing support position is appropriate. [New Content] - Therefore, the applicant has developed this creation case in response to the above problems, and then proposed the application of this patent. The main purpose of the creation is to provide a bicycle body structure improvement (1). It is installed in the position of the two ends of the five-way pipe socket of the vehicle body, and the five-way pipe seat is assembled with a dust-proof and waterproof Φ pipe body through which the shaft rod penetrates, and the dust-proof waterproof pipe is externally and in vitro. The end system is provided with a protruding stop portion, and a retaining ring is arranged on the lower edge of the blocking portion, and a threaded portion is formed on the inner wall at both ends of the five-way pipe seat for the dust-proof waterproof pipe body and the shaft rod in the sleeve After entering, the two ends of the dust-proof waterproof pipe body are screwed by the external thread section of the front end of the pipe diameter, so that the shaft in the dust-proof waterproof pipe body can be prevented from being dust-proof and waterproof. Another object of the present invention is to provide a five-way pipe structure improvement (1) for a bicycle body, wherein a five-way pipe base is assembled with a dust-proof and waterproof 0-pipe body, and a dust-proof waterproof pipe body is placed in the shaft. After the rod, it is screwed by a pipe diameter at both ends of the dust-proof waterproof pipe body, and a bearing is assembled in the rear end of the pipe diameter to have a stable supporting effect on the shaft. A further object of the present invention is to provide a five-way pipe structure improvement of a bicycle body (1). In addition, a two-stage different outer diameter sleeve may be separately assembled between the dust-proof waterproof pipe body and the pipe diameter. The pipe body is considered to be capable of assembling and assembling five-way pipe sockets of various pipe diameters by the casing body, so as to reduce the specification complexity of various parts and reduce the number of stock spares. 5 M295081 [Embodiment] First of all, please refer to the detailed descriptions of the first, second and third figures. In this case, the improvement of the five-way pipe structure of the bicycle body (1) refers to the five-way socket installed in the vehicle body. In the position of the two end sides, the five-way pipe base 1 is assembled with a dust-proof waterproof pipe body 3 through which the shaft 2 can be inserted, and the outer periphery of the dust-proof waterproof pipe body 3 is provided with protrusions. a blocking portion 31, and a retaining ring 3A is disposed on the lower edge of the blocking portion 31, and a thread_section 11 is formed on the inner wall of the five-way socket 1 for the dust-proof waterproofing pipe body 3 and the shaft 2 After being inserted, the two ends of the dust-proof waterproofing pipe body 3 are screwed by the external thread section 41 of the front end of the pipe diameter 4; thus, when the shaft 2 is placed in the dust-proof and waterproof pipe body 3 After that, the dust-proof waterproof pipe body 3 is again placed in the five-way pipe socket 1, and the external thread portion 41 of the front end of the two pipe diameters 4 is screwed with the threaded portion 11 of the inner wall of the two ends of the five-way pipe socket 1, and The inner wall of the outer thread segment 41 at the front end of the pipe diameter 4 touches the shackle ring 3A of the lower edge of the damper portion 31 of the waterproof pipe body 3 (as shown in the third figure), so that the outer surface of the yoke pipe socket 1 can be Possible intrusive dust The water vapor is blocked to protect the shaft 2 in the dust-proof and waterproof pipe body 3 from rust and contamination, resulting in unsatisfactory rotation. Further, a bearing 5 is assembled in the rear end inner space 42 of the pipe diameter 4, and the bearing 5 on both sides is positioned at the outermost end position of the five-way pipe holder 1, so that the stable support effect on the shaft 2 is enhanced. If the size of the five-way socket 1 is different, the M can be separately assembled between the dust-proof waterproofing pipe body 3 and the pipe diameter 4 by a two-stage 6 M295081 casing body 6 having different outer diameters (such as the fourth (5)) In this way, the assembly of the casing body 6 can be applied to the assembly of a five-way socket with a large diameter, which means that it has the dust-proofing and waterproofing and the stable support described above. At the same time, there is no need to prepare a large number of components of the specification, so that it can reduce the number of stock spares under the goal of "common supplies", and of course reduce the production cost of the operators and reduce the troubles in assembly. To sum up, the author of the above-mentioned creation structure meets the conditions for the establishment of Article 93 of the new type I patent; please ask for the establishment of the legal patent, and the grant of the legal patent right.
