SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides an external corner sander, include:
the rectangular frame comprises two fixing rods which are parallel to each other and two other holding rods which are parallel to each other;
the two-folding-angle scraping plates are parallel to each other, are provided with upward openings and are used for polishing the external-angle wall surface, and are respectively and vertically fixed on the two fixing rods;
one end of each of the four vertical rods is fixed to the four top ends of the rectangular frame and is perpendicular to the rectangular frame, and the other end of each of the four vertical rods is fixed to the bevel edge of each of the two bevel scrapers;
and the two connecting rods are respectively connected between the two bevel edges opposite to the two bevel scraping plates and are perpendicular to the two bevel scraping plates.
Adopt above-mentioned structural design, rectangular frame, pole setting, connecting rod are right two dog-ear scrapers play and support the effect of strengthening, simultaneously rectangular frame two holding rods make constructor convenient with both hands simultaneous control operating force degree, have guaranteed the construction effect as constructor's two handles.
The utility model relates to a further improvement of external corner sander lies in, the dog-ear of dog-ear scraper blade is the right angle.
Be the right angle through the dog-ear scraper blade makes the internal surface homoenergetic on two dog-ear limits contact the external corner wall can two-sided polishing simultaneously, and it is right to improve the once success rate that the external corner wall was polished is in addition right angled dog-ear makes the external corner sander is easier has guaranteed the squareness that the external corner wall was polished.
The utility model relates to a further improvement of external corner sander lies in, the top of dog-ear scraper blade is fixed in the mid point of dead lever.
Through the structure, the two holding rods are symmetrical relative to the two-fold-angle scraper, so that a constructor can apply balanced operating force to the second-stage fold-angle scraper through the two holding rods, polishing is more uniform and straight, and the effect is guaranteed.
The utility model relates to a further improvement of external corner sander lies in, the connecting rod connect in the mid point on the relative dog-ear limit of two dog-ear scrapers.
Through the structure, the connecting rod symmetry support in between the dog-ear scraper blade for operating force that constructor applyed can be even transmit extremely the dog-ear scraper blade, simultaneously, will the upper surface of connecting rod with dog-ear scraper blade internal surface keeps flushing, can increase the area of contact of external corner sander and external corner wall, further improves the effect of polishing.
The utility model relates to a further improvement of external corner sander lies in, two dog-ear scraper blade upper berths are equipped with the scraper blade, the scraper blade is used for polishing the external corner wall.
Through the scraper blade, will all the closing caps between the internal surface of bi-fold angle scraper blade for the external corner polisher full face contact treats the external corner wall of polishing, further improves the once-through success rate of polishing to the external corner wall.
To sum up, the utility model discloses a but not limited to following beneficial effect: with low costs, simple structure, wholly adopt the symmetry design, two handles make constructor control the operation dynamics more easily, be right angled dog-ear structure and have great with the area of contact of external corner wall makes this external corner sander have higher one time success rate at the in-process of polishing, and can guarantee right the squareness that the external corner wall was polished is easy and simple to handle save time, effectual.
Drawings
The following detailed description of embodiments of the invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a front view of the present invention;
fig. 3 is a left side view of the present invention;
fig. 4 is a schematic view of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1 to 4, as a preferred embodiment of the present invention, an external corner sander is formed by welding a plurality of square steel tubes, and includes:
a rectangular frame 20 including two fixing rods 21 parallel to each other and two other holding rods 22 parallel to each other;
the two bevel scraping plates 10 are parallel to each other, the openings of the two bevel scraping plates are upward, the two bevel scraping plates 10 are used for polishing an external corner wall surface, the vertex angles of the two bevel scraping plates 10 are respectively welded at the middle points of the two fixing rods 21, the two bevel scraping plates 10 are perpendicular to the rectangular frame 20, and the bevel of the two bevel scraping plates 10 is preferably a right angle in the embodiment;
one end of each of the four vertical rods 30 is welded to the four top ends of the rectangular frame 20, and is perpendicular to the rectangular frame 20, and the other end of each of the four vertical rods 30 is welded to the corner edge of the two corner scraper 10;
two connecting rods 40, the both ends of connecting rod 40 weld respectively in the midpoint department of two dog-ear scrapers 10 corresponding dog-ear limits, just connecting rod 40 is perpendicular to two simultaneously dog-ear scrapers 10, in addition, will connecting rod 40 upper surface with the internal surface of dog-ear scrapers 10 keeps flushing to increase the area of contact of external corner sander and external corner wall 50.
Through above-mentioned whole symmetry, be the right angled dog-ear to and the increase special construction such as area of contact of polishing, make whole external corner sander structure firm, two holding rods of constructor accessible 22 control the operation dynamics conveniently, make two dog-ear scraper blades 10 atresss is even, has improved right the success rate of external corner wall 50 polishing has guaranteed right in the same direction as straight, the side of external corner wall 50 polishing.
The structure can be further improved, namely the inner surface of the two bevel scrapers 10 is welded to be flat and is attached to the metal plate on the inner surface of the two bevel scrapers 10 to serve as a scraper for grinding the external corner wall surface 50, so that although the cost and the weight of the whole external corner grinder are slightly increased, the contact area between the external corner grinder and the external corner wall surface 50 can be maximized, the grinding of the external corner wall surface 50 can be improved to a large extent, and the effect is better.
