Existing a kind of combustion gas air filling gun by hook 1, rifle body 2, connecting rod 4, hinge hand 7, handle 9, switch base 14, stud 17, guide pillar 16, stopper head 20, answers back 21, compositions such as spring 6, sealing ring 22.The upper and lower side of rifle body 2 right parts is provided with dead slot 5, and connecting rod 4 front ends slide before and after dead slot 5 is done with hinged back, hook 1 rear end, and connecting rod 4 rear ends are hinged with hinge hand 7 by pivot pin 3, and rifle body 2 right part inner chambers are provided with spring 6.Rifle body 2 left parts are provided with guide pillar 16, be provided with stud 17 in this guide pillar 16, be provided with stage clip 18 between guide pillar 16 and the rifle body 2, these guide pillar 16 rears are provided with switch base 14, this switch base 14 is made up of knob 15, end cap nut 24, eccentric shaft 25, connecting ring 26, joint 13, knob 15 is connected with connecting ring 26 1 sides by eccentric shaft 25, and connecting ring 26 opposite sides link to each other with stud 17 1 ends.Described stud 17 other ends are connected with plunger 19, and these plunger 19 front ends are fixed with stopper head 20, these stopper head 20 the place aheads be provided with the band sealing ring 22 answer back 21.During inflation, 21 hook cylinder joint by linking up with 1 with answering back, pull back handle 9,21 cylinder joints of answering back seal.Turning knob 15 is to 2 deads in line of rifle body, and move behind the eccentric shaft 25 this moment, drives studs 17, plunger 19, stopper head 20 by connecting ring 26 and leaves and answer back 21, and combustion gas 21 charges into and filled in the steel cylinder until answering back through joint 13.With knob 15 half-twist angles, eccentric shaft 25 drives stud 17 and moves forward, and stopper head 20 seals 21 pores of answering back, and promptly stops inflation this moment.The air filling gun of the said structure part that comes with some shortcomings: (1) only is suitable for existing cylinder joint, can not be used for novel steel cylinder snap joint, because the axial dimension of these two kinds of joints is different, during inflated condition, hook front portion to the front end of answering back has only a fixing distance; (2) hook is anterior smooth, the unhook of skidding easily when the clamping cylinder joint; (3) do not establish safety device, might crush hand during operation.

The purpose of this utility model is to provide a kind of safe and reliable combustion gas air filling gun, and it not only can be applicable to existing cylinder joint inflation, also can be applicable to novel steel cylinder snap joint inflation, can be applicable to two kinds of joint inflations that axial dimension is different simultaneously.

The purpose of this utility model is achieved in that a kind of combustion gas air filling gun, comprise the rifle body, be loaded on the hinge hand and the handle of the hook of rifle body right front portion, right back portion, can before and after doing, rifle body right part dead slot slide after connecting rod front end and hook rear end are hinged, rod rear end is hinged with the hinge hand by pivot pin, and rifle body rear portion inner chamber is equipped with spring; Rifle body left part is provided with guide pillar, be provided with stage clip between rifle body and the guide pillar, in this guide pillar stud is housed, by sealing ring, answer back, pneumatic head that plunger is formed is connected with the stud front end, the stud rear end is connected with switch base, drive stud by eccentric shaft, connecting ring and do forward and backward moving, described hinge hand is provided with hook-type shift chute, and rod rear end is hinged by pivot pin and hook-type shift chute first anchor point or second anchor point.Described hook front end cross bar rear portion central authorities are provided with concave arc.Described rifle body both sides are provided with flap.

Advantage of the present utility model is to be suitable for two kinds of cylinder joint specifications and uses, and promptly not only is suitable for the usefulness of conventional cylinder joint inflation, also is suitable for the usefulness of novel steel cylinder snap joint inflation; Simultaneously, also has safe and reliable effect.

Fig. 1 is the utility model structural representation.

Fig. 2 is an A-A cutaway view shown in Figure 1.

Fig. 3 is a B-B cutaway view shown in Figure 1.

By following embodiment the utility model is further elaborated.

Referring to Fig. 1, Fig. 2, shown in Figure 3, the composition and the syndeton of an embodiment combustion gas of the utility model air filling gun are as follows: hook 1 is loaded on rifle body 2 right front portion, hinge hand 7 and handle 9 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 slips before and after dead slot 5 is done up and down, connecting rod 4 rear ends are hinged with hinge hand 7 by pivot pin 11, rifle body 2 right part inner chambers are equipped with spring 6 between pivot pin 3 and hinge hand 7, hinge hand 7 can rotate around pivot pin 12, hinge hand 7 is provided with hook-type shift chute 10, this chute 10 has two anchor points, promptly is positioned at first anchor point and second anchor point 8 that is positioned at groove hook place of pivot pin shown in Figure 1 11 positions.Rifle body 2 left parts are provided with guide pillar 16, are provided with stage clip 18 between rifle body 2 and the guide pillar 16, and stud 17 is housed in the guide pillar 16, and stud 17 front ends are connected with pneumatic head, and this pneumatic head is by plunger 19, stopper head 20 and answer back 21, sealing ring 22 forms; Stud 17 rear ends are connected with switch base 14, this switch base 14 is made up of knob 15, end cap nut 24, eccentric shaft 25, connecting ring 26, O-ring seal and joint 13, turn knob 15, drive studs 17 by eccentric shaft 25, connecting ring 26 and move forward and backward, the open and close state of 21 pores of can realizing answering back.1 front end cross bar rear portion central authorities are provided with a concave arc at hook, unhook can be able to not appearred skidding in cylinder joint fastening firmly, and are as safe as a house reliable.In rifle body 2 both sides flap 27 is housed, this is a kind of safety measure, in order to avoid cause personal injury.

During inflation, cylinder joint is filled in the charge gun clamping, select first or second anchor point of hinge hand 7 according to different joints, if this steel cylinder uses snap joint, pivot pin 11 should be selected to be positioned on hinge hand 7 first anchor points, if this steel cylinder uses conventional joint, then pivot pin 11 should be selected to be positioned on hinge hand 7 second anchor points 8, because of two kinds of joint axial dimensions differ 29mm.Move handle 9, connecting rod 4 just drives hook 1 joint is hooked, and prepares inflation, with hand knob 15 is threaded to and guide pillar 16 deads in line, then eccentric shaft 25 moves after driving stopper head 20 by connecting ring 26, and combustion gas, charges in the steel cylinder up to answering back 21 pores then through joint 13, switch base 14.After the sufficient combustion gas, knob 15 is threaded to and guide pillar 16 axis normal, then eccentric shaft 25 drives stopper head 20 reaches by connecting ring 26, and stopper head 20 seals up 21 pores of answering back, and at this moment, is closed condition.
