Door frame gap polyurethane-filling device for building decoration

Abstract

The invention relates to the technical field of decoration polyurethane-filling equipment, and discloses a door frame gap polyurethane-filling device for building decoration. The door frame gap polyurethane-filling device comprises a filling device body, wherein the filling device body is composed of a grab handle and a cross rod I; a gravity center adjusting mechanism is arranged on the cross rodI; bottled polyurethane is put into a shell body I and rotated; through the rotation of the polyurethane bottle, threads on the body of the polyurethane bottle are connected with the threaded mouth of a connector; the weight of the polyurethane with which the polyurethane bottle is fully filled is larger than that of the used polyurethane bottle; through the gravity of the polyurethane bottle, the shell body I is driven to turn to the right; a connecting rod is pushed by the shell body I to slide into an arc plate I and to compress a spring I; through the oblique placement of the polyurethanewith which the polyurethane bottle is fully filled, the gravity center of the polyurethane on the shell body I is lowered; and consequently, the gravity center of the whole device is lowered, the resisting arm for force application to the shell body I of the polyurethane bottle is shortened, the hand power exerted when a constructor holds the grab handle to fill a gap is reduced, the holding stability is improved, the filling precision and effect are improved, and the hand fatigue feeling is reduced.

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.
