Abstract

The invention discloses a bicycle frame. The bicycle frame comprises a longitudinal beam and a cross beam, wherein the top end of the longitudinal beam is connected with the left end of the cross beam; the bottom end of the longitudinal beam is connected with the right end of the cross beam through a supporting beam; a rear fork is mounted at the top end of the longitudinal beam; the bottom end of the longitudinal beam is connected with a cross fork; the rear fork is welded with the cross fork; a damping spring, a low-pressure air chamber and a high-pressure chamber are mounted in the longitudinal beam and are connected in sequence from top to bottom. The bicycle frame has the beneficial effects that an inflating assembly is arranged in a bicycle body, so that the inflating assembly is convenient to take; when the inflating assembly inflates, the used air is accumulated at ordinary times, so that the bicycle frame is energy-saving and environment-friendly; the inflating efficiency is high because of bipolar pressurizing.

Description

technical field [0001] The invention relates to the field of bicycle accessories, in particular to a bicycle frame. Background technique [0002] The tires of bicycles need to be inflated regularly after using for a certain period of time. Existing gas pumps, air pumps etc. are generally dedicated to bicycles, but these devices are all separated from bicycles. There are some small-sized air pumps with suspension in the existing bicycles, but most of the time in the use of the bicycle does not need to be pumped, and long-term carrying of the external air pumps will cause inconvenience to travel. Contents of the invention [0003] The purpose of the present invention is in order to solve the above-mentioned problem, has designed a kind of bicycle frame. The specific design scheme is: [0004] A bicycle frame, comprising a longitudinal beam and a crossbeam, the top of the longitudinal beam is connected to the left end of the crossbeam, the bottom end of the longitudinal bea...
