Description

Jetting machine metal rifle

Technical field

The utility model relates to a kind of cleaning device, particularly a kind of jetting machine metal rifle.

Background technology

Jetting machine is one of important accessory of jetting machine with the metal rifle.At present, the prior art jetting machine is with all being to adopt the mode that is threaded to be connected usually between the barral of a gun of metal rifle and the small of the stock, though this structure that is threaded is simple, but in long-term use, the repeated disassembled and assembled of the barral of a gun and the small of the stock can cause the helicitic texture wearing and tearing, therefore very easily cause producing between the small of the stock and the barral of a gun loosening, thereby reduce the sealing that is connected between barral of a gun and the small of the stock, cause barral of a gun and small of the stock junction to leak, if helicitic texture serious wear, even sliding tooth also can take place, make barral of a gun can't be connected, thereby reduce the normal service life that jetting machine is used the metal rifle with the small of the stock.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of barral of a gun and the small of the stock easy to connect, the jetting machine of long service life metal rifle.

For solving the problems of the technologies described above, the utility model provides a kind of jetting machine of following structure metal rifle: comprise the small of the stock, gun barrel, barral of a gun and rifle head, gun barrel is located in the small of the stock, the rifle head is connected with the barral of a gun right-hand member, wherein, also comprise adapter sleeve, volute spring, connector and rotary sleeve, the adapter sleeve left end is connected with the gun barrel right-hand member, its right-hand member is provided with jack, the connector right-hand member is connected with the barral of a gun left end, its left end is provided with the plug that can be inserted in the jack, the adapter sleeve inwall is provided with annular protrusion, and its outer wall is provided with outer step, rotary sleeve is enclosed within on the adapter sleeve, its left end inwall is provided with the interior step that matches with outer step, its right-hand member outer wall is provided with step, small of the stock right-hand member withstands on the step side-walls, the volute spring left end withstands on the side-walls of annular protrusion, and be close on the adapter sleeve inwall, its right-hand member withstands on the plug left end, is provided with two fixture blocks on the connector outer wall symmetrically, and the rotary sleeve inwall is provided with can be for the groove of fixture block insertion, the rotary sleeve of groove one side is provided with through hole, and the right-hand member of through hole is provided with block against the sidewall of groove.

Jetting machine described in the utility model metal rifle, wherein, also comprise the barral of a gun handle, the barral of a gun handle is made up of two and half covers, the connector right-hand member is provided with and is provided with two fixed blocks symmetrically, the barral of a gun taper knob partly overlaps the left end inwall and is provided with the holddown groove that matches with fixed block at barral of a gun left end place.

After adopting said structure, unlike the prior art, the utlity model has following advantage: when the utility model jetting machine uses with the metal rifle, the user can hold barral of a gun, connector is inserted in the rotary sleeve, the plug of connector left end can be inserted in the jack of adapter sleeve right-hand member and compressed volute spring this moment, rotate rotary sleeve again, make fixture block leave groove and lean against through-hole side wall place away from groove one end, unclamp the hand of holding barral of a gun then, connector can move right and finally make fixture block to withstand on the sidewall of through hole right-hand member under the bounce effect of volute spring this moment, thereby finish being connected of the small of the stock and barral of a gun, at this moment, under the stopping that is located at the block of through hole right-hand member on the recess sidewall, rotary sleeve can't relatively rotate with connector again, thereby can guarantee effectively that barral of a gun can not separate with the small of the stock; After the utility model jetting machine is finished using with the metal rifle, the user can hold barral of a gun and it is pushed away left, and connector will and be removed the restriction of block to left movement this moment, rotate rotary sleeve again, make fixture block leave through hole and get back in the groove, barral of a gun can be separated with the small of the stock then.Therefore, the utility model jetting machine is not only easy to use, and has avoided the screw connection structure defective of wearing and tearing easily, thereby has prolonged the utility model jetting machine service life greatly.

The utility model jetting machine is to make the user hold barral of a gun in the labour-saving more with the effect of barral of a gun handle in the metal rifle, thereby makes more simple that the dismounting of barral of a gun becomes, thereby further facilitates the use of the utility model jetting machine with the metal rifle.
