Abstract

The invention relates to a self-tightening system for shoes and a vacuum pump thereof. The self-tightening system comprises an air bag assembly and the vacuum pump, wherein the air bag assembly and the vacuum pump are attached to an upper part and a sole part respectively; the vacuum pump comprises a first cover and a second cover, and when the second cover is located at a first position relativeto the first cover, a cavity is formed between the first cover and the second cover; when the second cover moves from the first position to the second position relative to the first cover, the chamberis compressed to force fluid in the chamber to flow out through a discharge communication channel; when the second cover moves from the second position to the first position relative to the first cover, fluid in the airbag assembly is introduced into the chamber through a suction communication channel. The self-tightening system of the present invention allows a wearer to re-form the upper of a shoe for the wearer by pedaling a vacuum pump with a foot to evacuate the airbag assembly, thereby ensuring proper fit of the shoe.

Description

technical field [0001] The invention relates to a product for shoes, in particular to a self-fastening system for shoes and a vacuum pump thereof.
