Abstract

The utility model relates to a plastering tool which comprises a knife blade and a handle. The utility model is characterized in that the knife blade is bent into an arc, and the back of the knife blade is provided with a regulating mechanism which regulates the curvature of the knife blade. The regulating mechanism is two regulating sheets which are respectively provided with a plurality of holes, and is positioned through fixed pins on the handle. The curvature of the knife blade can also be regulated through the structures of a threaded rod, a nut, etc. The utility model is suitable for the plastering of the inner and the outer circle-arc wall corners, and the same arch of everywhere of the wall corners or the curved faces can be ensured. The verdant operator can also rapidly complete the plastering operation of the wall corners and the curved faces, and the efficiency and the operating quality can be obviously raised.

Description

Curved surface plastering tool

The utility model relates to plasters in the builing industry and instrument that troweling is used.

Normally used trowel comprises one flat plate and a handle in the plastering construction.Only suitable floating of this trowel for the building curved surface, then seems very difficult as outside corner of wall or cylinder in the various circular arcs, not only waste time and energy, efficient is low, is difficult to grasp, and plaster second-rate, the radian of bent angle be difficult to guarantee to be difficult to reach construction requirement by uniformity everywhere.Because it is bigger to smear the curved surface difficulty, generally need experienced operator's operation of higher skill.

The purpose of this utility model is to overcome above-mentioned difficulties, and a kind of floater that is suitable for smearing the interior various arc-shaped curved surfaces of outside corner of wall is provided, and can guarantee corner or curved surface radian uniformity everywhere.

Solution of the present utility model is: the blade of the usefulness of will plastering bends to arc, and the governor motion of regulating blade curvature is set at the blade back.

Above-mentioned governor motion can adopt following form, promptly along two porous adjustment sheets of blade horizontally set, utilizes the steady pin on the handle to be located.The tight son of spiral that also can adopt the bolt and nut structure positions as tensioning apparatus.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of corner arc-shaped curved surface floater.

Fig. 2 is the structure chart with outside corner of wall curved surface floater of same design.

Referring to Fig. 1, the back of cambered blade 1 longitudinally is provided with handle 2, and handle curves with band iron, is welded on the blade.Blade is generally made with spring steel.In order to regulate the radian of blade, laterally be provided with two porous adjustment sheets 6,7 at the blade back, the outer end is fixed, and has adjustment hole 9,10 on it.The size of radian as required during use, mobile porous adjustment sheet inserts the hole on it in the steady pin 5 on handle 2, can obtain the arc shape of different curvature.Steady pin 5 is located at the inboard of handle among the figure.When plastering, hold stop handle longitudinally before and after or move up and down, can smear out curved surface with same radian.

Can also there be other various ways in the mechanism that regulates cambered blade 1 curvature, finishes as the tight son of spiral with screw rod, nut structure, when rotating nut, can decontrol or tighten up dehiscing of cambered blade.This class formation also belongs to protection domain of the present utility model.

Said structure can be used for smearing outside corner of wall equally, handle 2 need only be moved to another side with adjusting curvature mechanism and get final product, as shown in Figure 2.These two kinds of structures have same idea, are two different embodiment of same design.Steady pin 5 is located on the end face of handle 2 among Fig. 2, and two porous adjustment sheet distortion backs cooperate with pin.

The utility model is suitable for plastering of inside and outside circle arc corner, can guarantee that corner or curved surface all have same radian everywhere, and make wipe one's face smooth.Even unskilled operator also can finish corner curved surface plastered work fast, obviously improve work efficiency and operation quality, this instrument has extensive use in building finishing.

Claims

1, a kind of floater comprises blade 1 and handle 2, it is characterized in that said blade 1 bends to arc, is provided with the governor motion of regulating blade curvature at the blade back.

2, floater as claimed in claim 1 is characterized in that said governor motion is two the porous adjustment sheets 6,7 along blade 1 horizontally set, by 5 location of the steady pin on the handle 2.

3, floater as claimed in claim 1, it is characterized in that said governor motion be screw rod, nut structure spiral tightly the son.
