Abstract

The utility model discloses an inflating gun which is characterized in that the utility model comprises a clamping device on a gun body and an inflating device, wherein, the clamping device comprises a gun hook arranged on the gun body, a clamping rod articulated with the gun body, a gun hook reset spring, a connecting rod and a valve sleeve which is arranged in the gun body and is provided with a reset spring, wherein, the connecting rod is connected with the clamping rod and the gun hook. The inflating device is arranged on the valve sleeve, and comprises an inflating gun head, a valve core, a valve core gland, a valve core spring causing the valve core to be reset, and a thread sleeve. The inflating gun with the scheme causes the courses of actions to have continuity and integrity, and the actions are that the air gun head is clamped, air is fed, an air feed valve is closed, and the gun head is loosened.

Description

A kind of charge gun

The utility model relates to a kind of charge gun.

At present, household liquified vapour is in China's use that become basically universal, but the automaticity of the inflator at most of gas station is also not high, especially the overall process that clamps, unclamps 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 charge gun.

For achieving the above object, the utility model adopts following scheme:

A kind of charge gun, it is characterized in that including clamp device and inflator on the rifle body, this clamp device includes the rifle hook that is arranged on the rifle body, is articulated in the clamp lever of rifle body, rifle hook Returnning spring, connecting rod and the valve pocket that has Returnning spring, wherein connecting rod connects clamp lever and rifle hook; Inflator is arranged on the valve pocket, include charge gun head and valve core, spool gland, make valve core spring, the thread bush of valve core reset, be with thread bush in the valve pocket, 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 on valve pocket.

Aforesaid 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.

The charge gun of such scheme, 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:

Fig. 1: the structural representation during the utility model work;

Fig. 2: structural representation when the utility model quits work.

As shown in the figure, this charge gun includes clamp device and inflator, this clamp device is formed (also being connected with suction tude 19 on the valve pocket 6) by the valve pocket 6 of the rifle hook 5 on the fixing rifle body 1, the clamp lever 2 that is articulated in rifle body 1, rifle hook Returnning spring 3, connecting rod 4 and band Returnning spring 7, wherein connecting rod connection clamp lever 2 and rifle hook 5; Inflator is arranged on the valve pocket 6, this inflator is by charge gun head 8, valve core 10, valve core gland 15, the valve core spring 16 that spool 10 is resetted, thread bush 11 is formed, be with thread bush 11 in the valve pocket 6, be with in the thread bush 11 and can make the spool 10 (this spool 10 is by seal washer 12 and thread bush 11 inner wall sealings) that axial seal is slided with respect to thread bush 11, spool 10 outer termination charge gun heads 8, the spool gland 15 (this spool gland is by the end face seal of rubber washer 14 with running-on 13) of termination sealing thread cover running-on 13 end faces in the spool 10, valve core spring 16 is installed in the valve pocket 6

This automatic charge gun adopts the charge gun head 8 of taper, is provided with the gland 18 of band seal washer 17 at the bottom of the awl of rifle head 8 along the position, limit, has pore 9 on conical surface position.

During use, the suction tude 19 that is connected on the valve pocket 6 is joined with the liquefaction tracheae.Endoporus with charge gun head 8 aligning cylinder joint bodies presses down clamp lever 2, and connecting rod 4 pulling rifle hooks 5 retreat, clamp the steel cylinder angle steel with rifle head 8, and force spool 10 to retreat, make rubber washer 14 leave the end face of thread bush running-on 13, spool endoporus and suction tude endoporus are connected.Like this, liquid gas enters steel cylinder through suction tude 19 endoporus, spool 10 endoporus, charge gun head pore 9; After inflation finished, with clamp lever 2 pull-ups, rifle hook 5 resetted under the effect of rifle hook Returnning spring 3, unclamps cylinder angle valve, and valve core spring 16 work meanwhile promote spool gland 15 reach sealing thread cover running-ons 13 end faces, close liquid gas (as Fig. 2).
