Abstract
The utility model discloses a seat tube inflator for a bicycle, which comprises a bicycle frame, a saddle seat, a seat tube, an outer cylinder of an inflating tube, a piston rod of the inflating tube, an air tube and an inflating nozzle, wherein the upper half part of the hollow seat tube forms the outer cylinder of the inflating tube, the air tube and the inflating nozzle are arranged at the lower half part of the seat tube, and a tightening ring capable of preventing the saddle seat from moving relative to the seat tube after being locked is arranged at the upper end of the seat tube. The whole inflating tube provided by the utility model is hidden in the seat tube of the bicycle, has the advantages of simple structure, convenient operation, low cost and reliable performance, cannot influence the whole outer structure of the bicycle, and can be applied in ordinary bicycles, folding bicycles and automatic bicycles.
Description
Technical field
The utility model relates to bicycle, specifically, is a kind of seat tube inflator of bicycle.
Background technology
Bicycle is the vehicle that people use always, and it brings great convenience for people's trip, but along with the use of bicycle, tire often need be inflated, sometimes in traveling process, and the unsaturated vapor of tire or do not had gas, make the bicycle can't cruising, such situation can often take place.
The existing bicycle that has Floor Pump, normally portable tire pump is clipped on certain position in the vehicle frame outside, perhaps the part of inflating with Floor Pump is provided with in the present pipe, tracheae is arranged on the outside, this structure all influences the attractive in appearance of bicycle, and tracheae is exposed in the air aging easily, and the complex structure of Floor Pump, the cost height uses inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to operate, the seat tube inflator of the bicycle that cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of seat tube inflator of bicycle, comprise cycle frame, saddle, seat pipe, the urceolus of air-inflating tube, piston rod, tracheae and the Air inflating valve of air-inflating tube, the hollow seat pipe first half constitutes the urceolus of air-inflating tube, tracheae and Air inflating valve are arranged in seat pipe lower part, and there is the bunching ring that after the locking saddle and seat pipe can not be relatively moved seat pipe upper end.
Described saddle is installed on the saddle pedestal, saddle pedestal below captive joint piston rod, piston rod is inserted in the seat pipe that forms the air-inflating tube urceolus, piston-rod lower end portion fastening one has the piston of seal ring, piston lower end captive joint one unidirectional valve seat, tracheae links to each other with unidirectional valve seat, and Air inflating valve is installed on the tracheae, described seat pipe connects and is inserted in the vehicle frame in the pipe, and is fixed in the vehicle frame on the pipe with the tight ring of saddle tube bundle.
An over cap is equipped with in described seat pipe bottom.
Present inside pipe wall captive joint one orienting lug moves up and down steadily piston rod.
Described tracheae is shrinkable spiral fashion India rubber tube.
Described bicycle is a folding bicycle.Described bicycle is an Electrical Bicycle.
Described catch gear is a bunching ring.
The beneficial effects of the utility model are: whole Floor Pump is all ensconced in the seat pipe of bicycle, and inflator structure is simple, and is easy to operate, and cost is low, and dependable performance does not influence the external overall structure of bicycle.
Description of drawings
Fig. 1 has the bicycle that has seat tube inflator of the present utility model to inflate view.
Fig. 2 is the seat tube inflator schematic appearance of bicycle of the present utility model.
Fig. 3 is the seat tube inflator structure cross-sectional schematic of bicycle of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, 2, 3, the seat tube inflator of the utility model bicycle, comprise cycle frame, saddle 1, seat pipe 2, the urceolus of air-inflating tube, piston rod 4, tracheae 7 and the Air inflating valve 8 of air-inflating tube, hollow seat pipe 2 first halves constitute the urceolus of air-inflating tube, tracheae 7 and Air inflating valve 8 are arranged in seat pipe 2 lower parts, there is a bunching ring 10 seat pipe 2 upper ends, and saddle 1 and seat pipe 2 can not be relatively moved.。
Specifically, described saddle 1 is installed on the saddle pedestal 3, saddle pedestal 3 below captive joint piston rods 4, piston rod 4 is inserted in the seat pipe 2 that forms the air-inflating tube urceolus, and piston rod 4 bottoms fastening have the piston 5 of seal ring, piston 5 lower end captive joints one unidirectional valve seat 6, tracheae 7 links to each other with unidirectional valve seat 6, Air inflating valve 8 is installed on the tracheae 7, and described seat pipe 2 connects and is inserted in the vehicle frame in the pipe 14, and is fixed in the vehicle frame on the pipe 14 with the tight ring 12 of saddle tube bundle.Piston 5 moves steadily and reduces friction when inflating for making, and an orienting lug 9 is connected in the seat pipe 2.An over cap 11 is equipped with in seat pipe 2 bottoms.Take off over cap 11 during use, adjustment seat pipe 2 is to suitable position, and tightly ring 12 is fastening with pipe place saddle tube bundle in the vehicle frame.Pull out tracheae 7, Air inflating valve 8 is linked to each other with bike tyre valve 13, unclamp bunching ring 10, the push-and-pull saddle just can be inflated to bike tyre up and down.
Because tracheae 7 is shrinkable spiral fashion India rubber tube, be convenient to take in the present pipe 2.
The seat tube inflator of bicycle of the present utility model can be used on ordinary bicycle, folding bicycle, the Electrical Bicycle.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
