For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of concealed seat tube inflator.The top of this Floor Pump comprises that the upper end that connects firmly is fixed with the cushion bracket of cushion, core bar and piston from top to bottom, and the bottom of this Floor Pump comprises the check valve that links from top to bottom and can be stretched to the air-inflating tube of front and back tire.The inner space of the seat pipe of cycle frame is divided into epicoele and cavity of resorption by dividing plate, and this check valve connects firmly in this dividing plate bottom.At the non-state of inflating:

This air-inflating tube is positioned at this cavity of resorption, and this core bar and this piston are positioned at this epicoele, and this cushion rack and this core bar of connecting firmly together are fixedly connected by nut and this pipe.

For above-mentioned Floor Pump, comprise in this check valve can be with two air pressure difference the glueballs of folding.

For above-mentioned Floor Pump, this epicoele top is provided with around this core bar to limit the nozzle collar of its position in this epicoele.

For above-mentioned Floor Pump, this air-inflating tube is made by elastomeric material.

For above-mentioned Floor Pump, at the non-state of inflating, this air-inflating tube is spring-like and curls in this cavity of resorption of lid is equipped with in the bottom.

For above-mentioned Floor Pump, this lid is a plastic cover.

For above-mentioned Floor Pump, this air-inflating tube is provided with the joint of inflating with inflation of tire mouth coupling at free end.

For above-mentioned Floor Pump, in the middle pipe that a section is fixed on this cycle frame in the middle of this pipe.

Advantage and characteristics that technical solutions of the utility model are main are as follows:

1, be a kind of concealed Floor Pump on the one hand: utilize the space of bicycle saddle tube, pump-up device is hidden in the inside, save and utilized the space effectively;

2, be that a kind of need not the dismounting can be realized the Floor Pump of inflating fast on the other hand: whole pump-up device does not need to disassemble from bicycle and can realize inflating when inflating, and is more easy at the whole process operation of inflating, and more meets the human engineering principle.
