Further; Between rifle core print and rifle core bar, seal ring is set; The upper end of seal ring is connected with the rifle core print, and the lower end of seal ring and rifle core bar leave the space, and the rifle core bar is provided with the convexity that closely contacts with seal ring being positioned at seal ring near the position of rifle core bar head one side.

Further, be fixedly connected through rifle core pin between top cover and the rifle core bar.

The useful technique effect of the utility model is:

When adopting the utility model that compressor inside is inflated; Source of the gas is through filling the suction port that air induction hose connects the fast aeration rifle, and the rifle skull of fast aeration rifle is connected with the rapid pipe joint of hermetic compressor, controls the inflation and the pressurize of compressor through pulling the piston rod; Simple to operate; Rate of fault is low, and can guarantee to realize the inflation to compressor inside fully, makes testing result more accurate.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the structural principle schematic representation of the utility model.

Among the figure: 1-rifle body; 2-charge gun head, 3-rifle core print, 4-seal ring, 5-packing ring, 6-jump ring, 7-rifle skull, 8-spanner retainer ring; The 9-spanner, 10-rifle core bar, 11-pushes up cover, 12-rifle core pin, 13-jump ring, 14-rifle core spring; The 15-piston column, 16-inflates gun breech, 17-piston rod pin, 18-roller, 19-piston rod, 20-push rod ball; 21-gun breech pin, 22-eccentric wheel, 23-charge gun gun breech connecting body, 24-position limit pin, 25-backing pin, 26-suction port.

Embodiment

In conjunction with accompanying drawing, a kind of fast aeration rifle, it comprises rifle body 1, and suction port 26 is set on rifle body 1, at the head of rifle body 1 rifle skull 7 is set, its flexible spanner 9 of rifle skull 7 and control is connected.Inner portion at the rifle body is provided with charge gun head 2, at the place, axle center of rifle body rifle core bar 10 is set, and in the inboard of 2 of charge guns rifle core print 3 is set, and leaves the space between rifle core bar 10 and the rifle core print 3.One section gap between rifle core print 3 and rifle core bar 10 is provided with seal ring 4; Seal ring 4 is between the suction port 26 and rifle skull 7 of rifle body; The upper end of seal ring 4 is connected with rifle core print 3; The lower end of seal ring 4 and rifle core bar 10 leave the space, and rifle core bar 10 is provided with the convexity that closely contacts with seal ring being positioned at seal ring near the position of rifle core bar head one side.Afterbody at rifle core bar 10 is provided with top cover 11; The afterbody outside at the rifle core bar is with rifle core spring 14; One end of rifle core spring 14 connects rifle core print 3, the other end connection top cover 11 of rifle core spring 14, and top cover 11 is connected with its push-rod assembly to rifle body head movement of promotion.Push-rod assembly comprises the inflation gun breech 16 that is sealedly connected on rifle body afterbody, and inflation gun breech 16 links together through charge gun gun breech connecting body 23 with rifle body 1, at the set inside piston column 15 of inflation gun breech 16.One end of piston column 15 connects top cover 11, and the other end of piston column 15 connects eccentric wheel 22, and piston column takes the shape of the letter U; The U-shaped mouth is towards eccentric wheel 22; Roller 18 is installed in the U-shaped mouth of piston column, and roller 18 rolls with eccentric wheel 22 and is connected, and roller 18 is fixed on the piston rod pin 17.Eccentric wheel 22 is connected with the piston rod 19 of its rotation of control, at the free end of piston excellent 19 push rod ball 20 is set.
