Abstract
The utility model discloses a high-pressure labor-saving inflator which relates to the inflating device for tyres of bicycles, motorcycles or automobiles, and is composed of a barrel, a piston-rod, a pressure-reducing bin and an air-charging nozzle. The lower part of the piston-rod is provided with an air-return groove and is sheathed with a sealed piston ring. The sealed piston ring is fitted to the piston-rod by a sliding mode, and is sealed together with the inner wall of the barrel by an interference mode. The pressure of the pressure-reducing bin at the bottom of the barrel can reach 8 kg per square cm, so that the automobile tires, etc., can be inflated easily. The utility model has the advantages of artful structure, long service life and labor-saving, and is adequate to be used as the inflating device for bicycle tyres, motorcycle tyres, automobile tires or rubber boats, etc.
Description
The utility model relates to a kind of manual pump of inflating to bicycle tyre or automobile tire of being used for.
The inflator of inflating in bicycle tyre mainly contains two classes, and a class is a dynamoelectric compressor, and another kind of is manual pump.Manual pump because easy to carry, do not need power supply, be most widely used inflator therefore.Manual pump of the prior art mainly is made of cylindrical shell and the piston or the leather cup that have handle and piston rod, leather cup is the bowl-type of back-off, be installed in the cylindrical shell and also can slide up and down therein, leather cup and cylinder inboard wall are interference sealing, handle leather cup to-and-fro motion in cylindrical shell by handle and piston rod and air pressure are contractd chewed by gas and charge in the bicycle tyre.The manual pump of this structure has two outstanding defectives, and the one, leather cup is easy to wear and lose seal action, has influenced the working life of pump; Next is that inflation pressure is very low, can only inflate in the low pressure tyre of bicycle tyre and so on, can't inflate in automobile tire.
The high pressure manual pump that the purpose of this utility model is a kind of long service life of design, inflation pressure is high.
In order to realize above-mentioned purpose, the utility model adopts sealed piston ring to replace existing sealing cup, to improve its sealing effect and working life, sets up a decompression storehouse simultaneously in the cylindrical shell bottom to improve its inflation pressure.Be described in further detail below in conjunction with the technical characteristics of specific embodiment the utility model cylinder effort-saving high-pressure air pump.
Accompanying drawing 1 is the structural representation of the utility model cylinder effort-saving high-pressure air pump.
With reference to the accompanying drawings 1, the utility model cylinder effort-saving high-pressure air pump is mainly chewed 4 by cylindrical shell 1, piston rod 2, decompression storehouse 3 and inflation and is constituted.Cylindrical shell 1 is a cylindrical shape, and the tube heading tape has a top cover 5, and the tube end has a pore and the needle-valve 6 that opens and closes this pore is housed.Piston rod 2 is a hollow cylindrical, is installed in the cylindrical shell 1, and between cylindrical shell 1 inwall certain interval is arranged, and its top is equipped with one handle 7 and is had the inlet hole 8 that is communicated with piston rod cavity.Have the air outlet hole 9 that is communicated with piston rod cavity on the underpart of the piston rod sidewall, the diameter of piston rod of air outlet hole below 9 is slightly little, have axial return-air groove 10 on it and be set with a sealed piston ring 11, sealing piston ring and piston rod 2 be for being slidingly matched, with cylinder inboard wall be the interference sealing.Decompression storehouse 3 is cylindrical, is installed in the bottom of cylindrical shell 1, and pore and needle-valve 6 bottom cylindrical shell are communicated with cylindrical shell 1 inner chamber, has on 3 sidewalls of decompression storehouse to be used to connect the air-filled pore 12 that inflation is chewed, and inflation is chewed 4 and promptly is communicated with this air-filled pore by flexible pipe 13.
Earlier mention piston rod during use by handle, sealed piston ring is owing to the frictional force with cylinder inboard wall moves down into the return-air groove bottom, and air is entered piston cylinder top and entered the cylindrical shell bottom through underpart of the piston rod return-air groove by the inlet hole and the piston cylinder top on piston rod top.When piston rod is pressed down, move on to return-air groove top on the sealed piston ring and form sealing and cylinder lumen pressure is increased, when pressure increased to a certain degree, tube spirit vent needle valve was opened, and pressurized air enters the decompression storehouse.And so forth, can make decompression storehouse pressure reach 8Kg/cm
2More than, not only can be used in bicycle tyre, inflating, and can be used in automobile tire, inflating.
The utility model structure is ingenious, easy to carry, the sealed piston ring long service life, and the inflation pressure height is particularly suitable for the inflator as bicycle tyre, automobile tire or rubber dinghy etc.
