Abstract

The utility model discloses a multifunction inflation tube which relates to a multifunction inflation tube used for inflating automobile tyres, basketballs, volleyballs, etc. The utility model comprises a joint, an inflating hose, and an inflating spout, and also comprises a hand control valve 1 and a pressure gauge 10, wherein the hand control valve 1 is provided with a cylindrical valve body 1', the interior of which is provided with an upper valve chamber 18, a core chamber 19 and a lower valve chamber 20 which are communicated; a valve rod 15 vertically penetrating through the valve chamber is fixedly provided with an upper valve core 16 and a lower valve core 17; the upper end of the valve rod 15 is hinged with a handle; the interior of the upper valve chamber 18 is provided with a spring 14, and the sidewall of the upper valve chamber 18 is provided with an air inlet 5; the sidewall of the core chamber 19 is provided with an air charging port 6; the wall of the lower valve chamber 20 is provided with an atmospheric pressure detecting port 9. The utility model also comprises a matching inflating needle 28 which can be inserted in an undercut 27 of the inflating spout. The utility model has the advantages that users can conveniently observe the air pressure situation of the inflated objects during inflation because the hand control valve and the pressure gauge are arranged additionally. The utility model has the advantages of easy use and safety. The utility model can inflate a ball, a rubber boat, a lifejacket, an inflatable packer, etc. by preparing an inflating needle which has a suitable external diameter and is matched with the inflating spout, and can inflate tyres of automobiles, tractors, motorcycles, etc. by pulling out the inflating needle. The utility model realizes the multifunction of display and inflation.

Description

A kind of multi-functional gas tube

Technical field: the utility model is related to the charge inflator of inflation usefulness such as boat of automobile tire, blue vollyball, rubber, mainly is meant multi-functional gas tube.

Background technique: existing gas tube, it is a long rubber hose, the one end is provided with rib-loop joint in the ears, its the other end is provided with the inflation of wrench switch and chews, during use, the ears joint is connected with source of the gas (automobile gas receiver or air compressor gas receiver), and the valve nozzle that the other end inflation is chewed with tire etc. joins, and mixes that to inflate the wrench switch of chewing promptly inflatable, its deficiency is, one, can not show the barometric information that is inflated object, use inconvenient, two, because of being inflated object valve nozzle difference, can only being inflations such as tire, and can not being of the object inflation of need such as blue vollyball with the Aerating needle inflation.

Goal of the invention: goal of the invention of the present utility model, be to overcome the deficiency of existing gas tube, existing gas tube is improved, a kind of multi-functional gas tube is provided, when inflation, can show inflating condition, again can with the supporting use of Aerating needle, both can be inflations such as automobile tire, can be inflations such as blue vollyball class again.

Content of the present invention is, a kind of multi-functional gas tube, comprise the ears joint 3 that connects source of the gas, inflated hose, inflation chews 8, inventive point is, inflated hose is connected to hand control valve 1, hand control valve is connected to barometer 10, described hand control valve 1 by valve body 1 ', hold handle 2, valve rod 15 with handle one end hinge, valve rod is provided with upper valve core 16 and lower valve core 17, spring 14 in the uuper valve chamber 18, be communicated with core chamber 19 between last lower valve chamber, the suction port 5 that is communicated with uuper valve chamber, the inflation inlet 6 that is communicated with the core chamber, the air pressure that is communicated with lower valve chamber 20 detects mouth 9 and related accessories constitutes.Also have simultaneously to insert and inflate the supporting Aerating needle of chewing in the end opening 27 28.

Good effect of the present utility model is, because of having set up hand control valve and barometer, can detect easily when inflation and observe the air pressure situation that is inflated object, and is easy to use, inflatable safety.And make the Aerating needle of suitable external diameter and inflation and chew supportingly, load onto Aerating needle and promptly can be inflations such as ball, rubber boat, safety garment, inflatable packer, pull up Aerating needle and then be tyre inflation such as automobile, tractor, motorcycle.Realize showing, inflate multi-functional.

Description of drawings:

Accompanying drawing 1 the utility model organigram

The supporting Aerating needle plan view of accompanying drawing 2 the utility model

Embodiment: the utility model organigram as shown in Figure 1, existing gas tube is a rubber hose, and an end is equipped with rib-loop joint 3 in the ears, and the other end is equipped with inflation chews 8, to have gas tube and disconnect adjunction one hand control valve 1, promptly constitute the utility model.This hand control valve have cylindric valve body 1 ', uuper valve chamber 18 is arranged in it, core chamber 19 and lower valve chamber 20 are connected, indulge on the valve rod 15 of wearing valve pocket and be fixed with upper valve core 16 and lower valve core 17, one of valve rod 15 upper ends and lever handle 2 end is hinged, be provided with spring 14 in the uuper valve chamber 18, trim ring 13 is arranged on it, be pressed under it on upper valve core 16, sealing gasket 12 is arranged on the trim ring, it on it gland 11, the uuper valve chamber sidewall has suction port 5, and external tracheae 4 is to ears joint 3, and core chamber 19 sidewalls have inflation inlet 6, external tracheae 7 to inflation chews 8, bottom sealing lower valve chamber 20 is arranged at the valve body bottom, and bottom has air pressure to detect mouth 9, connects barometer 10 through copper pipe.When holding handle 2 with a firm grip, valve rod and spool 16,17 move synchronously, close lower valve, open valve, and suction port 5 is communicated with inflation inlet 6, and be promptly inflatable; When unclamping handle, valve rod, spool move down under spring action and reset, and close to close valve, open lower valve, make inflation inlet 6 and air pressure detect mouth 9 and communicate, (suction port the when inflation inlet 6 of this moment becomes the air pressure detection), have in the reverse air pressure that is inflated object, enter barometer and shown.This multi-functional gas tube, its tracheae 4 parts are about 10 meters, and tracheae 7 parts are about 1 meter, and the general copper material that adopts such as the valve body of hand control valve, valve rod, spool, bottom, upper press cover is made, and handle can adopt iron piece or adopt engineering plastics to make.

It is that existing inflation is chewed that inflation chews 8, be the under shed cylindrical body, barrel is established hole 22 and is communicated with sidewall suction port 25, it in it cylindric piston 23, piston wall porose 24, when pushing an end and have the switch wrench 21 of cam configuration, piston will be pressed down, and hole 24 is communicated with 22, realize inflation, rubber ring 26 is compressed, wrap tightly and insert the valve nozzle that is inflated object in the end opening 27, charge gas trip switch wrench 21, piston resets under the elastic reaction of rubber ring, staggered in hole 22 and 24, close inflation.The piston core has the inverted cone structure, and its tip can be backed down being inflated the object valve nozzle.If with annex of the present invention---supporting Aerating needle 28 inserts inflation and chews under 8 in mouthfuls 27, can be to inflations such as ball, safety garment, rubber boat, inflatable packers.
