The invention relates to devices for dosing mounting foam. A device for dosing household mounting foam has a basic handle with the upper support for the hand and a platform that is rigidly, by means of two plates, attached to the basic handle, with thrust collar to which the balloon with mounting foam for household purposes is pressed. The handle-manipulator with pusher that is connected to the basic handle with rotary cramp transfers load from the hand to adapter, with opening the valve of the balloon. The adjusting screw doses foam output in required constant volume and if needed prevents accidental pressing the valve. The rotary pins fixed on the platform make it possible to reliably place the device on the surface. To fill the ceiling and difficult of access cavities a movable along the balloon, pressed with a spring, with extender and rotary section and elongated tube of foam guide is used. Using the extender the tube of the foam guide is to be fixed to the adapter with tightening, for instance with a coupling nut. To prevent losses of foam at interruption of foam filling and transportation of the device, the output section of the extender tube of the foam guide is pressed. The device makes it possible to work with mounting foam for household purposes at the level of professional pistols for mounting foam, and in some cases it has advantages. |
