Bicycle pump and bicycle provided with same

Abstract

The invention discloses a bicycle pump which comprises a bicycle pump body. The bicycle pump body is composed of a pumping rod and a straight cylinder. A through connection hole is formed in the bottom end face of the straight cylinder. A holding tube is fixedly connected with the upper end of the pumping rod. The lower end of the holding tube is provided with an opening, and the upper end of the straight cylinder can be sleeved with the opening. A containing cavity is formed in the upper end of the pumping rod. The upper end face of the holding tube is correspondingly provided with a through positioning hole and an air guide pipe. According to the bicycle pump, the upper end of the pumping rod is designed to be hollow, and the air guide pipe is contained in the containing cavity; the overall structure is simple and is in a straight rod shape, so that the bicycle pump is portable; and when the bicycle pump is in use, the air guide pipe is drawn out of the containing cavity firstly, a connection end with an external thread is connected with the connecting hole in a matched mode, then an inflating end with an internal thread is connected with the external thread of an air nozzle in a screw joint mode, and thus connection of an air circuit is achieved; and air pumping is achieved by drawing the holding tube back and forth.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to an air pump and a bicycle with the air pump. Background technique [0002] Because the bicycle is designed with an exposed structure, it is very inconvenient to carry items on the bicycle itself. If we find that the bicycle tire is flat when we go out, we have to go to the maintenance point to pump it, which will be very inconvenient. However, it is too cumbersome to carry the pump every day, so if Being able to integrate the pump into the bike's own components would solve this problem. [0003] Chinese patent CN204489072U discloses a bicycle beam structure integrated with an air pump, which includes: a bicycle beam, a pressure chamber is arranged in the bicycle beam, and a plurality of buckles are installed on the bicycle beam; In the pressure chamber of the bicycle beam; the leather tube, the leather tube communicates with the bottom end of the pressure chamber, and the leath...

AI Technical Summary

Problems solved by technology

[0004] Although it realizes the integration of the pump, the structure is complex, which increases the difficulty of processing the frame and leads to an increase in production costs

Moreover, because it is fully integrated, it will pose a limitation when using it, such as inconvenient when pumping up other bicycles
