An outer barrel of the pumping pipe is formed by the hollow seat tube. The saddle is installed on the hollow seat tube with the sealed upper end. An inner cavity of the hollow seat tube is provided with a piston which is capable of moving up and down along the inner wall surface of the seat tube and provided with a seal ring, the piston is provided with a one-way valve, the one-way valve is communicated with the cavity piston rod arranged on the lower portion of the piston, the piston rod is internally provided with a pumping rubber pipe which is capable of moving up and down in an inner cavity of the piston rod and capable of being pulled to the outside from the bottom of the piston rod, the pumping nozzle is installed in the pumping rubber pipe, a U-shaped retaining ring is hinged to the outer side of the lower end of the piston rod, and the U-shaped retaining ring can be inserted into the hollow seat tube. The pumping rubber pipe is located inside the piston rod, the U-shaped retaining ring is hinged, the space occupied by a handle is saved, the pumping volume is increased, and pumping efficiency is improved.
Description
Technical field
The utility model relates to bicycle pump, specifically, is a kind of concealed bicycle use Floor Pump.
Background technology
Bicycle is the conventional vehicle of people, and it brings great convenience to people's trip, but along with the use of bicycle, tire often need to be inflated, sometimes in traveling process, and the unsaturated vapor of tire or do not had gas, bicycle cannot normally be travelled, and such situation can often occur.
The existing bicycle with Floor Pump, in bicycle, in seat pipe and vehicle frame, pipe adopts perpendicular tight ring fastening.Seat pipe connects firmly with saddle.Therefore, seat pipe can be Floor Pump cylindrical shell, and piston, check valve, piston rod are housed in cylindrical shell, has air-inflating tube and the handle that can pull in piston rod.But, because handle is hidden in a tube cylinder, take a part of volume of cylindrical shell, make cylindrical shell effectively inflate volume and reduce.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, easy to operate, can effectively increase cylindrical shell and inflate the bike saddle tube pump of volume.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bike saddle tube pump, comprise saddle, seat pipe, the piston rod of air-inflating tube, tracheae and Air inflating valve, hollow seat pipe forms the urceolus of air-inflating tube, described saddle install is on the hollow seat pipe of upper end sealing, be provided with the piston with seal ring that can move up and down along seat inside pipe wall surface at hollow seat tube cavity, on piston, be provided with check valve, check valve communicates with the piston rod of the cavity that is arranged on piston bottom, in piston rod, have at piston rod cavity and move up and down and can move to from piston rod bottom the outside India rubber tube of inflating, inflate on India rubber tube Air inflating valve is installed, hinged outside piston-rod lower end portion " U " type clasp, " U " type clasp can be inserted in hollow seat pipe.
Side, described piston rod bottom is provided with breach, and the India rubber tube of inflating is moved outside to from the breach of piston rod bottom.
Described " U " type clasp front end is bent into the circular arc matching with piston rod external diameter.
An over cap is equipped with in described seat pipe bottom.
Present inside pipe wall is fixedly connected with an orienting lug, and piston rod is moved up and down steadily.
The beneficial effects of the utility model are: the India rubber tube of inflating is positioned at piston rod inside, and utilize hinged one " U " type clasp, have saved the shared space of handle, make to inflate volume to increase, and have improved and have inflated efficiency.
Accompanying drawing explanation
Fig. 1 is the collecting state structural representation of the utility model bike saddle tube pump.
Fig. 2 be the utility model bike saddle tube pump inflate status architecture schematic diagram.
Fig. 3 is the clasp block diagram of the utility model bike saddle tube pump.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Fig. 1, 2, shown in 3, bike saddle tube pump of the present utility model, comprise saddle, seat pipe, the piston rod of air-inflating tube, tracheae and Air inflating valve, hollow seat pipe 1 forms the urceolus of air-inflating tube, described saddle install is on the hollow seat pipe 1 of upper end sealing, be provided with the piston 2 with seal ring that can move up and down along seat pipe 1 inner wall surface at hollow seat pipe 1 inner chamber, on piston 2, be provided with check valve 3, check valve 3 communicates with the piston rod 4 of the cavity that is arranged on piston 2 bottoms, in piston rod 4, have at piston rod 4 inner chambers and move up and down and can move to from piston rod 4 bottoms the outside India rubber tube 5 of inflating, inflate on India rubber tube 5 Air inflating valve is installed, hinged " U " type clasp 6 outside piston rod 4 bottoms, " U " type clasp 6 can be inserted in hollow seat pipe 1.
Side, described piston rod bottom is provided with breach 7, and the India rubber tube 5 of inflating is moved outside to from the breach 7 of piston rod 4 bottoms.
Described " U " type clasp 6 front ends are bent into the circular arc 8 matching with piston rod external diameter.
An over cap 9 is equipped with in described seat pipe 1 bottom.
Present pipe 1 inwall is fixedly connected with an orienting lug 10, and piston rod 4 is moved up and down steadily.
When use, " U " type clasp 6 is hinged with piston rod 4 ends, rotates clasp 6 vertical with piston rod 4 while inflating, and India rubber tube 5 is inflated in pull-out, and snaps in piston rod end breach 7, tramps with one's feet and pushes down clasp 6, and push-and-pull saddle just can be given bicycle qi of chong channel ascending adversely up and down.Beaten and rotated clasp 6 after gas and touch piston rod 4 and put into a tube cylinder, so just can deduct the shared space of handle, " U " type clasp 6 front ends are bent into the circular arc 8 matching with piston rod external diameter.Seat tube cylinder 1 bottom is provided with screw thread and over cap 9 links.Piston rod end jagged 7 is in order to avoid push down air-inflating tube while inflating.
Above-described embodiment is only for illustrating technological thought of the present utility model and feature, its object is to make those skilled in the art can understand content of the present utility model and implement according to this, can not only limit the scope of the claims of the present utility model with the present embodiment, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the scope of the claims of the present utility model.
