Abstract
The utility model provides a frame system, and particularly relates to an arch-back through pipe frame system for a bicycle. The arch-back through pipe frame system comprises a main horizontal rod, a front fork rod, a main vertical rod, a main oblique rod, an upper tail rod and a lower tail rod. The right end portion of the main horizontal rod and the right end portion of the main oblique rod are fixed to the front fork rod. The left end portion of the main horizontal rod and the main vertical rod are fixed together in a plug-in mode. The bottom of the main vertical rod and the left end portion of the main oblique rod are fixed together through a pedal shaft rod. The left end portion of the upper tail rod and the right end portion of the lower tail rod are fixedly connected through calipers. The right end portion of the upper tail rod and the main vertical rod are fixed together. The right end portion of the lower tail rod and the pedal shaft rod are fixed together. The main vertical rod extends upwards. The arch-back through pipe frame system for the bicycle is compact in structure, using performance is improved, service life is prolonged, and safety is improved.
Description
Technical field
The utility model is a kind of frame system and frame, particularly a kind of poling of the hogback for bicycle frame system and frame.
Background technology
Bicycle of the prior art, the intensity of vehicle frame is not high, often causes the quality of vehicle frame easily to go wrong, and vehicle frame is de-frame easily, affects driving performance, reduces product specification simultaneously.
Summary of the invention
