Abstract
The utility model discloses a frictioning chi relates to frictioning apparatus field, has solved the easy remaining problem of current frictioning chi frictioning. It includes the frictioning chi body, and the both ends of frictioning chi body are equipped with arc chi head respectively, and outside extend the frictioning chi body and the cross section is sharp conical frictioning portion and constitutes for rectangular somatic part and to this somatic part left and right sides by the middle part cross section, uniform thickness in the middle of promptly, and edgewise attenuation gradually of both sides, the arc limit of arc chi head is 175 <= alpha < 180 in the two tangential contained angle alpha's that half central line corresponding to the frictioning chi body and fourth central line were located angle scope. The utility model discloses a frictioning chi simple structure, the both sides convenient glue to less gap department of frictioning portion of attenuation are gradually scraped and are got and the trowelling, set up the arc chi head that has a special arc curve at frictioning chi body both ends and facilitate the use object surface that the frictioning chi commute scraped the damage and carry out scraping of glue and get and the trowelling, avoid leading to the fact the injury to the bright and clean easy object surface that meets with scraping the damage.
Description
Technical field
This utility model be related to frictioning apparatus field and in particular to a kind of can to compared with the glue at small gap carry out scraping and
Trowelling, and the special-shaped frictioning chi that the bright and clean body surface being subject to scrape damage is damaged can be avoided.
Background technology
Frictioning chi be building and when fitting up using a kind of more frequently instrument, be generally used for scraping or apply daub
Water.Existing frictioning chi be mostly direct a leveling ruler is set, its during scraping glue or spreading glue, tiny seam
Glue at gap is very difficult to be applied to, and has certain limitation.In addition, the frictioning chi of leveling ruler shape is easily bright and clean to outside easy
The body surface damaging plays and certain hangs effect.
Utility model content
For solving the defect that above-mentioned technology exists, this utility model provides and a kind of can carry out to compared with the glue at small gap
Scraping and trowelling, and the special-shaped frictioning chi that the bright and clean body surface being subject to scrape damage is damaged can be avoided.
The technical scheme that this utility model realizes that above-mentioned technique effect adopted is：
A kind of frictioning chi, including frictioning chi body, described frictioning chi body be respectively arranged at two ends with arc chi head, described arc
The arc-shaped side of shape chi head is being cut corresponding to described 1/2nd centrages of frictioning chi body and the two of a quarter centerline
The angular range of the angle α of line is 180 ° of 175 °≤α ＜.
A kind of above-mentioned frictioning chi, described frictioning chi body is rectangular body and to described by middle cross section
The body left and right sides stretches out and cross section is constituted for the frictioning portion of sharp cone distal.
The beneficial effects of the utility model are：Frictioning chi structure of the present utility model is simple, the gradually thinning frictioning in both sides
Portion is convenient to be scraped and trowelling to compared with the glue at small gap, is arranged on frictioning chi body two ends and has special arc curve
Arc chi head convenient use frictioning chi carries out scraping and the trowelling of glue to the body surface being subject to scrape damage, it is to avoid be subject to bright and clean
The body surface scraping damage damages.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is cross-sectional view of the present utility model；
Fig. 3 is angled arrangement schematic diagram at described arc chi head for this utility model.
Specific embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, now comparison accompanying drawing is detailed
Specific embodiment of the utility model is described.
As shown in Figure 1 to Figure 3, a kind of frictioning chi, including frictioning chi body 1, frictioning chi body 1 be respectively arranged at two ends with arc
Shape chi head 2, the arc-shaped side of arc chi head 2 is in 1/2nd centrages corresponding to frictioning chi body 1 and a quarter centrage
The angular range of the angle α of two tangent lines at place is 180 ° of 175 °≤α ＜.Concrete as shown in figure 3, frictioning chi body 1 two/
Line a centered on one centrage, line b centered on a quarter centrage of frictioning chi body 1, centrage a are in the arc of arc chi head 2
Point c is intersected at, centrage b intersects at point d at the arc-shaped side of arc chi head 2, and the arc-shaped side of arc chi head 2 is in point c at shape side
The tangent line at place is c1, and the arc-shaped side of arc chi head 2 tangent line at point d intersects the angle of composition for d1, tangent line c1 and tangent line d1
For α, the angular range of angle α is 180 ° of 175 °≤α ＜, and it is easy to carry out lossless scraping to the buildings surface being subject to scrape damage
Or smear.Frictioning chi body 1 is rectangular body 11 and outside to body 11 left and right sides by middle cross section
Extend and cross section is constituted for the frictioning portion 12 of sharp cone distal.The gradually thinning frictioning portion 12 in both sides is conveniently to compared with the glue at small gap
Water is scraped and trowelling.
