Abstract

The utility model relates to an inflator, particularly an inflator combined with a bicycle. The inflator combined with a bicycle comprises an inflator body, a pull rod, a piston, a leather tube, a clamping head, etc. The utility model is characterized in that a bicycle frame is used as an inflator body, and a seat cushion is arranged on the upper end of the pull rod of the inflator and can also be used as an inflator handle. When the bicycle is not inflated, the seat cushion is fixed by a pin and a rotary cover on the pull rod. The utility model has the advantage of convenient use, and is suitable for various man and woman bicycles and is particularly suitable for export and rural areas.

Description

Bicycle pump

The utility model relates to a kind of inflator, is specifically related to a kind of inflator that combines with bicycle.

Traditional inflator product is comparative maturity, though inflator product newly developed upgrades on style to some extent, all is freestanding; Some be the inflator of bicycle designs specially, also is external hanging type, does not organically combine with bicycle.Thereby these inflators are convenient inadequately when using, and also claim not Shang saving economically.

The purpose of this utility model provides a kind of simple and convenient, economical and practical, really the inflator that combines with bicycle.

Technical solutions of the utility model are as follows: a kind of bicycle pump, comprise constituent elements such as cylindrical shell, pull bar, piston, leather hose, chuck, and it is characterized in that by cycle frame as air cylinder body; Seat cushion is installed in inflator pull bar upper end, but and double as inflator handle.

The pull bar that this bicycle pump links to each other with seat cushion has been provided with the pin of fixation, and the pin top also is provided with a spiral cover; Correspondingly be provided with the pin grooves of fixator pins in the cylindrical shell upper end, cylinder body outer wall then has screw thread and spiral cover to match.

Because the utility model utilizes cycle frame to make air cylinder body, has reduced the required seamless steel pipe of traditional inflator; Bicycle structure is not then changed substantially, but seat cushion double as inflator handle also.Make bicycle can both inflate so everywhere, lighter when riding, and can prolong working life of tire.In inflator time spent not, the pin on the pull bar is embedded in the pin grooves, and the spiral cover of pin top is tightened in cylinder body outer wall, and seat cushion is fixed, and can equally with ordinary bicycle ride.

Be described further below in conjunction with drawings and Examples.

Fig. 1 is the utility model bicycle pump scheme of installation.

Fig. 2 is the utility model bicycle pump structural representation.

Fig. 3 is an inflator rod section structural representation.

Fig. 4 is an air cylinder body upper end structural representation.

In the embodiment shown in fig. 1, bicycle pump comprises cylindrical shell, pull bar, piston, leather hose (7), chuck constituent elements such as (8), it is characterized in that by cycle frame (1) as air cylinder body; Seat cushion (2) is installed in inflator pull bar upper end, but and double as inflator handle.Can comparatively be clear that the concrete structure of the utility model inflator from Fig. 2: air cylinder body is divided into compression cabin (4) and hyperbaric chamber (6) two-part, have pore (11) to communicate between two cabins, the valve control pore of being made up of spring (9) and steel ball (10) (11) opens and closes.Tie component as shown in Figure 3, pull bar (3) lower end is piston (5), piston has apron (15) outward; Be provided with the pin (12) of fixation on the pull bar, the pin top also is provided with a spiral cover (13); The pull bar upper end is a cylinder (14), in order to seat cushion (2) to be installed.Correspondingly, be provided with the pin grooves (16) of fixator pins in the cylindrical shell upper end, cylinder body outer wall then has screw thread (17) and spiral cover to match, and end structure as shown in Figure 4 on the cylindrical shell.

The utility model working procedure is as follows: elder generation's derotation nut in the time of inflating, unclamp spiral cover (13); Catch bicycle saddle cushion (2) upwards to draw then, make pin (12) break away from pin grooves (16), turn over an angle, can inflate.When firmly pressing down, owing to compress cabin (4) gas pressure greater than spring (9) elastic force, steel ball (10) breaks away from pore (11), and gas enters hyperbaric chamber (6) from the compression cabin by pore (11), sends through the moccasin pipe (7) of hyperbaric chamber then, enters tire.When pull bar (3) when mentioning, piston (5) rises, and gas pressure is added spring force greater than the pressure in compression cabin in the hyperbaric chamber, makes steel ball be close to pore, and high pressure air can't be escaped from.So the work of inflating is finished in circulation.After having beaten gas, the angle of reversing embeds in the pin grooves pin; Tighten spiral cover, inflate end.Because pin (12) is embedded in the pin grooves (16), the pin top has spiral cover (13) to be tightened in cylinder body outer wall again, compresses pin, is just firmly fixed so be installed in the seat cushion of small end, can the same saddle horse with ordinary bicycle.

Also some other embodiment can be arranged for the utility model, for example make the inflator handle, but adorn a secondary handle in addition in the pull bar upper end without seat cushion.This bicycle pump can be used on the in men's style car of band tripod and not on the lady's bicycle with tripod.In addition, this principle also can be used on the tricycle.

Claims

1, a kind of bicycle pump comprises constituent elements such as cylindrical shell, pull bar, piston, leather hose, chuck, it is characterized in that: by cycle frame (1) as air cylinder body; Seat cushion (2) is installed in inflator pull bar upper end, but and double as inflator handle.

2, bicycle pump according to claim 1 is characterized in that: the pull bar (3) that links to each other with seat cushion (2) has been provided with the pin (12) of fixation, and the pin top also is provided with a spiral cover (13); Correspondingly be provided with the pin grooves (16) of fixator pins in the cylindrical shell upper end, cylinder body outer wall then has screw thread (17) and spiral cover to match.

3, bicycle pump according to claim 1 and 2, it is characterized in that: air cylinder body is divided into compression cabin (4) and hyperbaric chamber (6) two-part, have pore (11) to communicate between two cabins, the valve control pore of being made up of spring (9) and steel ball (10) (11) opens and closes.
