Abstract
The utility model discloses a bicycle five-way joint made of laminated bamboo boards. The bicycle five-way joint comprises a supporting tube and tenon heads. The tenon heads are connected with the supporting tube through tenon spacers. Tenon mouths are arranged in the supporting tube. The bicycle five-way joint made of the laminated bamboo boards is novel in design and simple in structure, enables a bicycle to accord with trends of the times, reduces the whole weight of the bicycle, and enables a frame of the bicycle to be more firm and durable through adoption of triangular stability and a mortise and tenon joint structure.
Description
Technical field
The utility model relates to the bicycle frame parts that a kind of bamboo ballast bamboo board is made, and is specifically related to a kind of bamboo ballast bamboo board five-way.
Background technology
Bicycle has just obtained extensively popularizing as a kind of traditional vehicle a long time ago, but along with socioeconomic fast development, improving constantly of living standard, especially the continuous progress of science and technology, the more and more modern means of communication and the mass transportation facilitieies such as aircraft, automobile, subway selected of people, bicycle weakens as acting on progressively of people's go off daily instrument.Yet the extreme weather that causes because of green-house effect these years suddenly increases, earthquake, and tsunami, heavy rain, the disasteies such as arid occur again and again.The mankind begin to think deeply the harmonious development of man and nature ground.In addition, along with the aggravation of environmental pollution and the puzzlement of various diseases, people's environmental consciousness and body-building consciousness is also improving constantly, and cycle racing has been got back to again in people's the life and has been subject to more widely that the parent looks at as a kind of green, sunshine sports.Bicycle has been the simple vehicle no longer, but has been endowed environmental protection and healthy concept, the bicycle assembly parts material also experienced by carbon steel alloy to carbon fiber matter development.Generally pay attention to the epoch of energy-saving and environmental protection people, a kind of new green environment protection bamboo ballast bamboo board bike tech and market are progressively ripe.Bamboo itself has high hardness, high tenacity as a kind of reproducible natural resource, the characteristics such as resistance to compression, tension and lightweight, and material is easy to obtain, and is convenient to processing and is beneficial to environmental protection.Bamboo wood by the different process moulding, is applied in the modern bicycle and can produce huge society and economic benefit.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of current material and technique, and a kind of bamboo ballast bamboo board bicycle bottom bracket is provided, and the product by the bamboo processing technology replaces metal or carbon fibre material, the fastness of Effective Raise bicycle, hand-held design.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of bamboo ballast bamboo board bicycle bottom bracket comprises support tube and tenon, and described tenon is connected with described support tube by the tenon pad, is provided with the tenon mouth on the described support tube.
Further, described support tube is set to annular arrangement, and described tenon mouth is set to ellipse.
The beneficial effects of the utility model are:
The utility model is novel in design, and is simple in structure, not only so that bicycle is complied with the trend in epoch more, also alleviates the overall weight of bicycle, utilizes leg-of-mutton stability and joinery and its construction to make vehicle frame firmer, durable.
