Abstract

The invention discloses a shock absorbing front fork with a pumping function. The shock absorbing front fork with the pumping function is characterized in that the bottom of a precise fixed guide rodis fixed with the bottom surface of an external lower fork tube; the top end of the precise fixed guide rod is in contact with the bottom of a telescopic spring; on the lower end of an upper stroke tube is mounted a reciprocating stroke piston which is located on the outer peripheral of the top end of the precise fixed guide rod; the outer peripheral surface of the bottom end of the reciprocatingstroke piston is mounted with a sealed piston ring rubber sleeve which is tightly coupled with the inner wall of external outer lower fork tube; an inner closed rubber sleeve is installed between theinner peripheral surface of the inner portion of the reciprocating stroke piston and the precise fixed guide rod; the lower end of the pipe wall of the external lower fork tube is provided with a circular hole with a diameter of 6.5 millimeters. The shock absorbing front fork with the pumping function has the advantages of achieving versatile features of the shock absorbing front fork, being multifunctional, and having no need to carry a pump.

Description

technical field [0001] The invention relates to the fields of bicycles and electric vehicles, and more specifically relates to a shock-absorbing front fork with an air pumping function. Background technique [0002] Existing shock-absorbing front forks of bicycles and electric vehicles use flexible connections between iron or aluminum pipes, supplemented by the flexible characteristics of springs, to reduce bumps from uneven ground, or use the mixture of oil and gas to achieve telescopic and shock-absorbing functions , the function is relatively simple. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a shock-absorbing front fork with an air pumping function. [0004] The shock-absorbing front fork with inflating function of the present invention is realized through the following technical scheme. The lower end of the upper stroke tube is inserted into the outer lowe...
