Pointing device for tiles at indoor corners

Abstract

The invention relates to a pointing device, in particular to a pointing device for tiles at indoor corners. The pointing device comprises an air bag, a circular pipe connected with the air bag and two brushes connected to the circular pipe. The circular pipe is of a hollow structure with one closed end, a circular hole is formed in the closed end of the circular pipe, a conical pipe is arranged on the circular hole, and the caliber of the big end of the conical pipe is equal to the diameter of the circular hole. The two brushes which are perpendicular to each other are arranged on the circular pipe and located on the two sides of the conical pipe. The tail ends of the brushes and the small end of the conical pipe are located at the same height. The air bag is arranged at the open end of the circular pipe and provided with an air one-way valve, an opening is formed in the upper side face of the circular pipe, a straight pipe is arranged on the opening, and a circular cover is arranged on the straight pipe and connected with the straight pipe in a threaded mode. The pointing device for the tiles at the indoor corner has the advantage of being applicable to pointing of the tiles at indoor corners.

Description

technical field [0001] The invention relates to a pointing device, in particular to an indoor corner tile pointing device. Background technique [0002] Ceramic tile is a common interior decoration material. It is an acid and alkali resistant porcelain or stone material formed by grinding, mixing, pressing, glazing and sintering of refractory metal oxides and semi-metal oxides; After pasting, there will be a certain gap between two adjacent tiles. Now the joints are mainly done manually, using a hook knife to fill the joints one by one, and filling the appropriate joints on the adjacent tiles through tools. In the gap between tiles, tile pointing is the last process of tile construction in the decoration industry, which directly reflects the appearance and construction quality; but there is a problem: the original method of manual filling is less efficient, especially at the corner of the wall The grout is more difficult to remove.
