Bicycle fork body device

Abstract

The invention relates to a bicycle fork body device. The bicycle fork body device comprises a bifurcated rod, a connecting rod and an accessory, wherein the bifurcated rod comprises two hollow supports and a base portion for connecting one ends of the two supports, and a combined hole which runs through the top end of the base portion to the bottom end of the base portion is formed in the base portion; the accessory arranged in the combined hole comprises a pipe casing part and a long pipe fitting, wherein the pipe casing part is arranged in the combined hole in an assembling manner; a set of holes are additionally formed and run through the pipe casing part; the long pipe fitting penetrates through the set of holes; an annual retaining part extends outward on the peripheral side of the long pipe fitting at one end close to the bifurcated rod; an insertion space is formed between an outer wall surface of the long pipe fitting and an inner wall surface of the pipe casing part; the connecting rod is sheathed in the long pipe fitting and enters the insertion space towards the direction of the bifurcated rod. According to the device, the accessory is set, so that the connecting rod can be quickly connected with the bifurcated rod, a fork body can maintain the existing strength, the overall weight can be lightened, and the occurrence of cracks and damages can be reduced.

Description

Technical field [0001] The present invention is a bicycle fork body device. In detail, it reduces the weight of the bicycle fork body and reduces the occurrence of breakage between the fork rod and the connecting rod of the fork body. It is an invention with excellent practicability. Background technique [0002] In today’s bicycles, the pursuit of lightweight design methods can increase the speed of the rider. However, the better the bicycle, the more expensive and complicated parts are used. As a result of the increase in the overall bicycle weight and wind resistance, the riding situation is affected. Therefore, how to meet the needs of most riders without reducing the functions of the bicycle and the price has become a topic that the related industry now attaches great importance to. [0003] In order to meet the lightweight concept without losing the function of the overall bicycle, the industry has racked their brains on the bicycle body to achieve a lighter weight effect. Am...

Problems solved by technology

[0005] The above-mentioned "front fork and steering tube combination device" is a modular bicycle front fork, which is made of aluminum alloy or magnesium alloy to reduce the overall weight of the bicycle. However, with the development of today's technology, aluminum alloy and magnesium Alloy still has a slight weight, and the thickness of the tube wall after assembly is relatively thin. Therefore, when the bicycle is riding, the steering tube is subjected to a large external force due to the control of the steering of the front fork. Under such a structural design , it is easy to cause the edge of the front fork hole to be easily damaged and form cracks

Therefore, the connecting device between the front fork and the steering tube is indeed easy to shorten the service life, and the rupture and damage at the edge of the hole cannot be repaired by maintenance, and it must be replaced with a new one to continue to use, thus causing a cost increase. Increase and other disadvantages

[0006] In view of the above-mentioned shortcoming, the inventor has used a lot of time to invest in relevant knowledge, compare the advantages and disadvantages, and carry out research and development of related products, and after many experiments and tests, finally released a "bicycle" Fork device", it is to improve the above-mentioned prior art, the weight of the front fork made of metal material is too heavy, and because the tube wall after assembly is thin, the front fork is easier to act on its external force Defects such as cracks and damage at the edge of the hole
