Abstract

The utility model relates to an inflator, and in particular relates to an adjustable inflator. According to the technical scheme, the adjustable inflator comprises a pull rod handle, a pedal, an air pipe and a lifting air cylinder, wherein the lifting air cylinder is arranged on a positioning cylinder; a plurality of limiting holes and an air pipe slot are formed on the positioning cylinder; the air pipe extends out of the air pipe slot and can move up and down; a limiting slot is longitudinally formed on the outer side of the lifting air cylinder; and the height of the lifting air cylinder is fixed through a limiting valve and the limiting holes on the positioning cylinder. The adjustable inflator has the beneficial effects that 1, an adjustment cylinder is arranged on the basis of the conventional inflator; 2, indentation between the positioning cylinder and the lifting cylinder is controlled in a limiting hole manner, so that the whole length of the air cylinder can be changed; and the adjustable inflator has the characteristics of flexibility of use, high efficiency and the like.

Description

Adjustable pump

Technical field

The utility model relates to a kind of pump, particularly a kind of adjustable pump.

Background technique

When people use pump, receive its steam outlet pipe on the valve of bicycle tyre, the effect of valve is only to allow air to get into tire from pump, does not allow air to blow back into pump from tire.Between the piston of pump and the barrel space is arranged, have individual on the piston to recessed rubber cup. when upwards drawing piston, the volume of air of piston below increases; Pressure reduces; The air of piston top just is extruded into the below around rubber cup. and when pressing down piston, piston below volume of air is dwindled, and pressure increases; Making rubber cup be tight against barrel does not allow air to drain to the piston top; Continuation is to pressing down piston, and when atmospheric pressure was enough to back down the valve inside of tire, pressurized air just got into tire. and the outer air of tube gets into the top of piston from the space of tube upper end simultaneously.The problem that existing pump exists is: because user's height has nothing in common with each other, like this, tall user is wasted time and energy when using comparatively short and small pump, uses very inconvenient.

Summary of the invention

The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of adjustable pump is provided, and can make pump be fit to the user of different heights.

Its technological scheme is: comprise pull bar handle, pedal, tracheae and up-down inflator, described up-down inflator is installed on the location cylinder, and described location cylinder is provided with a plurality of spacing holes and a tracheae groove, and tracheae stretches out through the tracheae groove and can move up and down; The outside of up-down inflator vertically is provided with a restraining groove, through the height of the spacing hole fixed elevated inflator on limited valve and the location cylinder.

The beneficial effect of the utility model is: the one, and on original pump basis, increase and regulate tube; The 2nd, control the indentation between location cylinder and the lifting tube with the spacing hole mode, thereby change the entire length of inflator, have the characteristics such as comfortable, efficient of using.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is side views of the utility model;

Accompanying drawing 3 is partial view of the utility model;

Among the last figure: pull bar handle 1, pedal 2, tracheae 3, location cylinder 4, up-down inflator 5, spacing hole 6, limited valve 7, restraining groove 8, tracheae groove 9.

Embodiment

In conjunction with accompanying drawing 1-3, the utility model is done further to describe:

The utility model comprises pull bar handle 1, pedal 2, tracheae 3 and up-down inflator 5; It is characterized in that: described up-down inflator 5 is installed on the location cylinder 4; Described location cylinder 4 is provided with a plurality of spacing holes 6 and a tracheae groove 9, and tracheae 3 stretches out through tracheae groove 9 and can move up and down; The outside of up-down inflator 5 vertically is provided with a restraining groove 8, and through the height of the spacing hole 6 fixed elevated inflators 5 on limited valve 7 and the location cylinder 4, thereby the people that adapt to different heights use.

The one, on original pump basis, increase and regulate tube; The 2nd, control the indentation between location cylinder and the lifting tube with the spacing hole mode, thereby change the entire length of inflator, have the characteristics such as comfortable, efficient of using.
