Ink fountain with convenience in line changing for building construction

Abstract

The invention discloses an ink fountain with convenience in line changing for building construction, which aims to solve the problems that the line in a conventional ink fountain is complex in changing and easy to jam. The ink fountain comprises an ink fountain box formed by a lower bottom groove and an upper close cover, wherein a line wheel chamber and an ink storing chamber are arranged inside the ink fountain box; a line wheel rocking handle shaft with a polygonal radial section is movably mounted in the line wheel chamber; a line wheel shaft penetrates and is coaxial with the line wheel rocking handle shaft; a plurality of line wheel blades are mounted along the circumference of the line wheel shaft; a ink line is wound on the plurality of blades; and one end of the ink line penetrates out of the ink storing chamber after being wound on the blades. According to the ink fountain provided by the invention, the ink fountain box of the ink fountain is formed by the lower bottom groove and the upper close cover, during line changing, a box body is opened to change the line directly; the line wheel rocking handle shaft is non-cylindrical, so as to avoid relative sliding between the line wheel rocking handle shaft and the line wheel shaft during processes of line releasing or line winding; and meanwhile, line fastening holes, which are formed in the line wheel blades, facilitate penetration of the ink line, so that the phenomenon that the line winding is messed to form a mixed ball is avoided.

Description

technical field [0001] The invention relates to an auxiliary tool for construction engineering, in particular to an easy-change ink fountain for construction. Background technique [0002] Ink fountain is an indispensable tool for measuring and positioning in building construction. The existing ink fountain for building construction mainly includes a wire wheel chamber and an ink storage chamber; Wheel blades, the plurality of wire wheel blades are wound with ink lines; the ink storage chamber is equipped with a sponge that absorbs ink; the ink line passes through the sponge in the ink storage chamber through the wire wheel chamber and then passes through the outlet hole on the wall of the ink storage chamber wear out. In the long-term use process, it is found that the ink fountain of this structure has the following shortcomings: [0003] (1) Since the radial section of the handle shaft of the wire wheel is circular, the handle shaft of the wire wheel and the shaft of th...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the radial section of the handle shaft of the wire wheel is circular, the handle shaft of the wire wheel and the shaft of the wire wheel will slide relative to each other, resulting in inaccurate wire setting control or inability to retract the ink line;

[0004] (2) There is a gap between the two ends of the spool shaft and the side wall of the spool chamber. When the ink line is recovered, the ink line is easily twisted into the gap, resulting in unsmooth pay-off or take-up;

[0005] (3) When changing the thread, it is necessary to pass the thread back through the outlet hole, through the ink storage chamber, then through the outlet hole in front of the thread wheel chamber, and then tie it to the thread wheel shaft, which is troublesome to operate
