A polyurethane filling device for door frame gaps for building decoration

Abstract

The invention relates to the technical field of polyurethane filling equipment for decoration, and discloses a polyurethane filling device for door frame gaps for building decoration, including a filling device body. The filling device body is composed of a handle and a cross bar. A gravity center adjustment mechanism is arranged on the cross bar. Put the bottled polyurethane into the shell and turn it to make the thread on the polyurethane bottle connect with the threaded port on the connection port. The full bottle of polyurethane is heavier than the used one, and the gravity of the polyurethane bottle drives the shell. Body one turns to the right, and shell one pushes the connecting rod to slide into arc plate one and compresses spring one. By placing the full bottle of polyurethane obliquely, the center of gravity of polyurethane on shell one is lowered, thereby lowering the center of gravity of the entire device and shortening The resistance arm of the polyurethane bottle exerting force on the shell can reduce the hand force of the construction workers when holding the handle to fill the gap, improve the stability of holding, improve the accuracy and effect of filling, and reduce the fatigue of the hand.

Description

technical field [0001] The invention relates to the technical field of decoration polyurethane filling equipment, in particular to a polyurethane filling device for door frame gaps for building decoration. Background technique [0002] In the decoration process, after the doors and windows are installed, there are gaps between the doors, windows and the wall. Polyurethane is often used to fill the gaps. The polyurethane filling device connects the canned polyurethane to the filling device, and controls the outflow of polyurethane through the switch mechanism. In order to ensure the filling effect of polyurethane, the polyurethane filling device places the bottle vertically. When the tank is full, the polyurethane makes the center of the whole device upper, and increases the resistance arm, which increases the strength of the hand holding the filling device. Long-term Use causes hand fatigue, the center is not good for the stability of holding, and there is a phenomenon of de...

[0002] In the decoration process, after the doors and windows are installed, there are gaps between the doors, windows and the wall. Polyurethane is often used to fill the gaps. The polyurethane filling device connects the canned polyurethane to the filling device, and controls the outflow of polyurethane through the switch mechanism. In order to ensure the filling effect of polyurethane, the polyurethane filling device places the bottle vertically. When the tank is full, the polyurethane makes the center of the whole device upper, and increases the resistance arm, which increases the strength of the hand holding the filling device. Long-term Use causes hand fatigue, the center is not good for the stability of holding, and there is a phenomenon of deviation during use, which affects the filling accuracy.
