Abstract
The utility model discloses an automatic inflating gun which comprises a pneumatic clamping device and an automatic inflating device, wherein the pneumatic clamping device comprises a cylinder, a hollow piston rod and a gun hook fixed to a cylinder casing, and the hollow piston rod penetrates through a front cover and a back cover of the cylinder. The automatic inflating device is arranged on the hollow piston rod, and comprises an air inlet pipe, an inflating gun head, a valve core center, a valve core press cover, a valve core spring for resetting a valve core and a screw thread sleeve. The automatic inflating gun with the proposal makes the action courses of clamping the gun head, feeding air, closing an air feed valve, loosening the gun head, etc. have continuity and integrity.
Description
The utility model relates to a kind of charge gun.
At present, household liquified vapour air feed in big or middle city mostly concentrates on large-scale gas station, and the steel cylinder aeration at large-scale gas station all is to adopt the way of inflation automatically.But the automaticity of the device of above-mentioned inflation is also not high, especially clamps and the process of unclamping the rifle head almost is manual process, and clamps the rifle head, supplies gas, closes to supply gas valve and unclamp the rifle head and be difficult to form continuous, incorporate process.
At the problems referred to above, the purpose of this utility model be to provide a kind of can be clamping the rifle head, supply gas, closing to supply gas valve and unclamp the first-class course of action of rifle and form continuity, incorporate automatic charge gun.
For achieving the above object, the utility model adopts following scheme:
A kind of automatic charge gun is characterized in that including air clamper and self-filler, and this air clamper includes cylinder, hollow piston rod, is fixed in the rifle hook on the cylinder shell, and hollow piston rod is through the protecgulum and the bonnet of cylinder; Hollow piston rod is provided with self-filler, this self-filler includes suction tude, charge gun head and valve core, spool gland, makes valve core spring, the thread bush of valve core reset, hollow piston rod taps into tracheae in the port of rear end cover position, in the port of cylinder front cover position, be with thread bush, being with in the thread bush can be with respect to the spool of screw thread interplanting axial seal slip, spool outer termination charge gun head, the spool gland of termination sealing thread cover running-on end face in the spool, valve core spring is installed in the hollow piston rod endoporus.
Aforesaid automatic charge gun, its further scheme is that the charge gun head is tapered, is provided with the gland of band seal washer at the bottom of the awl of rifle head along the position, limit, has pore on conical surface position.
As above fast automatic charge gun, its further solution is to have one air reversing valve to be installed and to be communicated with extraneous air passageways on the cylinder, between piston and the protecgulum inwall piston spring that makes piston reset is arranged.
The automatic charge gun of such scheme owing to used cylinder and Returnning spring, make air gun clamping rifle head, supply gas, close to supply gas valve and unclamp the first-class course of action of rifle and have continuity, integrality.
Below in conjunction with accompanying drawing the utility model is further specified:
Shown in accompanying drawing be the structural representation of automatic charge gun described in the utility model.
As shown in the figure, this automatic charge gun includes air clamper and self-filler, this air clamper is made up of cylinder 1, hollow piston rod 2, the rifle hook 3 that is fixed on the cylinder shell, and wherein hollow core piston rod 2 is through the protecgulum 9 and the bonnet 18 of cylinder; Hollow piston rod 2 is provided with self-filler, this self-filler is by suction tude 20, charge gun head 4, valve core 8, valve core gland 12, the valve core spring 13 that spool 8 is resetted, thread bush 7 is formed, wherein hollow piston rod 2 taps into tracheae 20 in the port of bonnet 18 positions, in the port of cylinder protecgulum 9 positions, be with thread bush 7, be with in the thread bush 7 and can make the spool 8 (this spool 8 is by seal washer 10 and thread bush 7 inner wall sealings) that axial seal is slided with respect to thread bush 7, spool 8 outer termination charge gun heads 4, the spool gland 12 (this spool gland is by the end face seal of rubber washer 11 with running-on 21) of termination sealing thread cover running-on 21 end faces in the spool 8, valve core spring 13 is installed in hollow piston rod 2 endoporus.
This automatic charge gun adopts the charge gun head 4 of taper, is provided with the gland 6 of band seal washer 5 at the bottom of the awl of rifle head 4 along the position, limit, has pore 22 on conical surface position.
Also have one air reversing valve 16 to be installed and to be communicated with extraneous air passageways 17 on the cylinder 1 of this automatic charge gun, these air passageways 17 external port also are connected to air inlet and chew 19, between cylinder piston 15 and protecgulum 9 inwalls piston spring 14 that piston 15 is resetted are arranged.
During use, compressed air hose and air inlet are chewed 19 be connected, suction tude 20 is joined with the liquefaction tracheae.The charge gun head is aimed at the endoporus of cylinder joint body, selector valve 16 is stirred to one side, pressurized air enters cylinder 1, promote cylinder piston 15, compression piston spring 14, drive hollow piston rod 2 and push away charge gun head 4 before rapidly and clamp the steel cylinder angle steel, and force spool to retreat to make spool gland 12 to leave the end face of thread bush running-on 21, spool endoporus and the connection of hollow piston rod 2 endoporus with rifle hook 3.Like this, liquid gas enters steel cylinder through suction tude 20, hollow piston rod 2 endoporus, spool 8 endoporus, charge gun head pore 22; After liquid gas is full of in the steel cylinder, again the air reversing valve spool is dialled to another side, this moment, piston spring 14 work promoted piston 15, charge gun head 4 retreats, cylinder 1 compressed air is discharged through air reversing valve 16, valve core spring 13 work meanwhile promote spool gland 12 reach sealing thread cover running-ons 21 end faces, close liquid gas.
