Abstract

The utility model relates to a gas filling gun. The gas filling gun does following improvement on the connecting head part of the existing hook-type gas filling gun: a tip core is arranged on the connecting head part of the existing hook-type gas filling gun. The rear end of the tip core and the front end of a tip nozzle are in sealed connection by a sealed ring. The middle-rear part of the tip core mounted inside a connecting sleeve is a multi-angle star shape core rod, and the multi-angle star shape core rod and the inner wall of the adjacent connecting sleeve form a plurality of vent grooves. The side parts of the front ends of the vent grooves are provided with O-shaped sealed rings. The front part of the tip core is provided with a thin and long solid core round rod. The gas flowing amount of the structure is large, the tip core does not need to contact the three sealed rings of a connecting head, and thus, the gas filling gun has the beneficial effect of a fast gas filling speed, high efficiency, convenient and quick operation, etc.

Description

A kind of combustion gas air filling gun

Technical field

The utility model relates to combustion gas inflation technical field, particularly a kind of combustion gas air filling gun.

Background technique

The structure of existing a kind of manual combustion gas air filling gun is such: shown in accompanying drawing 1, hook 1 is loaded on rifle body 2 right front portion, hinge hand 6 and handle 7 thereof are loaded on rifle body 2 right back portions, connecting rod 4 front ends and hook 1 rear end can be after hinged by pivot pin 3 along rifle body 2 right parts slip before and after dead slot is done up and down, connecting rod 4 rear ends are hinged with hinge hand 6 middle parts by pivot pin 8, hinge hand 6 bottoms are hinged by pivot pin 9 and rifle body 2 rear portions, rifle body 2 right part inner chambers are equipped with spring 5 between pivot pin 3 and hinge hand 6, rifle body 2 left parts are provided with guide pillar 13, be provided with stage clip 12 between rifle body 2 and the guide pillar 13, stud bolt 11 is housed in the guide pillar 13, stud bolt 11 front ends are connected with plunger 15, plug 16 and by answering back 18, connecting sleeve 20, the pneumatic head that seal ring is formed, connecting sleeve 20 rear portions are connected with 18 outer wall threads of answering back, stright pipe shaped gun nozzle 23 by connecting sleeve 20 front portions and air outlet hole 22 thereof insert cylinder joints and with joint in three O-ring seals be tightly connected, and then to pneumatic inflation.Stud bolt 11 rear ends are connected with switch base 10, this switch base 10 is made up of knob, end cap nut, eccentric shaft, connecting ring, O-ring seal and joint, the turn knob drives stud bolt 11 by eccentric shaft, connecting ring and moves forward and backward, the open and close state of the pore of can realizing answering back.In rifle body 2 both sides flap is housed also.During inflation, charge gun mouth 23 is inserted cylinder joints, move handle 7, connecting rod 4 just drives hook 1 cylinder joint is hooked, and prepares inflation.Be threaded to and guide pillar 13 deads in line with the knob of hand with switch base 10, move after stud bolt 11 drives plug 16, combustion gas charges in the steel cylinder through four air outlet holes 22 of rifle mouth 23.After the sufficient combustion gas, knob is threaded to and guide pillar 13 axis normal, then stud bolt 11 drives plugs 16 reaches, and plug 16 seals up 18 the pore of answering back, at this moment, i.e. and closed condition.It is less that the air filling gun of said structure adds tolerance, influenced aerating efficient; Because the rifle mouth will insert in the cylinder joint and be tightly connected with three O-ring seals, frictional force was big when insertion was pulled out, and is relatively more painstaking, also damages these seal rings easily, causes gas leakage.

Summary of the invention

In order to strengthen aeration quantity, easy-to-operat, raising charging efficiency, and provide the utility model combustion gas air filling gun.

Realize that the technical solution of the utility model is such: a kind of combustion gas air filling gun, comprise the rifle body portion, hook 1 is contained in rifle body 2 right front portion, hinge hand 6 and handle 7 thereof are contained in rifle body 2 right back portions, can before and after doing, rifle body 2 right part dead slots slide after connecting rod 4 front ends and hook 1 rear end are hinged, connecting rod 4 rear ends are hinged with hinge hand 6 middle parts by pivot pin 8, and hinge hand 6 bottoms are hinged by pivot pin 9 and rifle body 2 rear portions, and rifle body 2 right part inner chambers are equipped with spring 5; Rifle body 2 left parts are provided with guide pillar 13, are provided with stage clip 12 between rifle body 2 and the guide pillar 13, in this guide pillar 13 stud bolt 11 are housed, and its front end is connected with plunger 15, plug 16 and answers back 18; Stud bolt 11 rear ends are connected with switch base 10; Flap also is equipped with in rifle body 2 both sides, connecting sleeve 21 rear portions are connected with 18 outer wall threads of answering back, also be provided with plunger tip 22, these plunger tip 22 rear ends are connected with 18 forward end seal of answering back by seal ring 19, plunger tip 22 mid-rear portions that are contained in the connecting sleeve 21 are polygonal star plug 23, form many vent slots 17 with adjacent connecting sleeve 21 inwalls, be provided with O-ring seals 20 at these vent slot 17 front end sidepieces, plunger tip 22 front portions are elongated solid pole.

Compared with prior art, the beneficial effects of the utility model are that aeration quantity is big, convenient to operation, thereby aerating speed is fast, the efficient height; Because the air flue of air filling gun and cylinder joint is by O-ring seals 20 sealings, thereby can save three O-ring seals in the cylinder joint air flue.
