Referring to fig. 1 to 5, the present embodiment provides a scraper structure for paving, which can be applied to the aviation field for paving a composite material sheet.

Spread and paste and use scraper blade structure including connecting plate 11 and scraper blade, one side of connecting plate 11 forms the portion of gripping, and the scraper blade includes scraper blade body 21 and scraping part 22, and the opposite side and the scraper blade body 21 of connecting plate 11 can be dismantled and be connected, and scraping part 22 sets up in the one side that connecting plate 11 was kept away from to scraper blade body 21, and the both ends of scraping part 22 all form the closed angle portion, and at least one end of scraper blade body 21 forms fillet portion 211.

It will be appreciated that the sharp corners facilitate placement in linear positions and the rounded corners 211 facilitate placement compaction and inspection in the R corners. Since the fillet portion is located at the scraping portion 22 and the fillet portion 211 is located at the squeegee body 21, the fillet portion 211 and the fillet portion do not interfere with each other.

When using, the operator can hold the portion of gripping with the hand, and scraping portion 22 can be used for the shop of large tracts of land combined material tablet to paste, because scraping portion 22's both ends all form the bight for it is inseparable to spread the subsides, and at least one end of scraper blade body 21 forms bight 211, and bight 211 and bight mutually noninterfere use bight 211 to spread when pasting, can not receive the influence of bight, and it is convenient to use, spreads to paste efficiently, can be applied to large-scale production.

Specifically, one end of the scraping part 22 forms a first sharp corner 221, the other end of the scraping part 22 forms a second sharp corner 222, the rounded corner 211 is located on the side of the first sharp corner 221 close to the connecting plate 11, the rounded corner 211 and the first sharp corner 221 do not interfere with each other, and when the rounded corner 211 is used for paving, the rounded corner is not affected by the first sharp corner 221, and similarly, when the first sharp corner 221 is used, the rounded corner 211 is not affected. The first pointed portion 221 can be adapted to the rounded portion 211

The angle of the first sharp corner 221 is different from the angle of the second sharp corner 222 to adapt to different paving conditions. In the present embodiment, the angle of the first pointed portion 221 is 90 degrees, and the angle of the second pointed portion 222 is less than 90 degrees.

The portion of gripping includes holding pole 12 and the hole 13 of gripping, and holding pole 12 sets up in the lateral part edge of connecting plate 11, holds the hole 13 and opens on connecting plate 11. When the hand-held electric tool is used, the hand grasps the holding rod 12, and fingers extend into the holding hole 13 to apply force conveniently. The holding rod 12 and the connecting plate 11 may be joggled or bonded.

In the present embodiment, the grip lever 12 has a cylindrical shape, which reduces discomfort in the palm of the operator and enables long-time gripping without fatigue. In this embodiment, hold hole 13 and be rectangular form, the corner that holds hole 13 sets up the arc chamfer, can not scratch the staff, and the operating personnel of being convenient for snatchs, and finger tip ache problem when improving the operating personnel and spreading.

The grip portion further includes a handle 14, and the end of the grip rod 12 is connected to the handle 14. Since the handle 14 is provided so as to apply a force to the handle 14 during use, the rounded portion 211 of the squeegee body 21 is urged to improve the placement efficiency, and therefore, the handle 14 and the rounded portion 211 are provided diagonally as shown in fig. 2.

The edges of the handle 14 and the holding rod 12 are rounded, so that safety guarantee is provided, and the hands of people are prevented from being accidentally injured.

In this embodiment, the handle 14 extends in an arc shape and is bent in a direction close to the squeegee body 21, so that a force is applied to the handle 14.

The connecting plate 11 is joggled with the scraper body 21, so that the scraper body 21 can be prevented from rotating relative to the connecting plate 11. Specifically, the connecting plate 11 is provided with a first mortise 111, one side of the scraper body 21 forms an installation portion 212, and the installation portion 212 is inserted into the first mortise 111. In the present embodiment, the first tongue-and-groove 111 is formed as a trapezoidal groove, and the squeegee body 21 is prevented from falling off along the first tongue-and-groove 111. Of course, the first mortise 111 may be configured as a circular arc groove, and the angle of the circular arc is greater than 180 degrees. The shape of the mounting portion 212 is adapted to the shape of the first mortise 111.

Furthermore, a first mounting hole 112 is formed in the connecting plate 11, a second mounting hole 213 is formed in the scraper body 21, and the first mounting hole 112 is connected with the second mounting hole 213 through a locking member 31. The mortice is assisted by the locking member 31, and the squeegee body 21 is prevented from sliding back and forth in the extending direction of the first mortise 111 during use.

In this embodiment, the locking member 31 includes a bolt and a nut, the bolt is disposed through the first mounting hole 112 and the second mounting hole 213, and the nut is threadedly coupled with the bolt.

It can be appreciated that when the scraper body 21 is worn, it is easy to replace, and the connecting plate 11 can be reused, saving costs. The scraper bodies 21 with different sizes can be replaced to adapt to different paving working conditions.

In this embodiment, the connecting plate 11 has a trapezoidal plate shape, the end connected to the grip portion is a short side, and the end connected to the scraper body 21 is a long side, so that when the pointed portion and the rounded portion 211 are used, the grip portion does not interfere with each other, the length of the scraping portion 22 is ensured, and the pasting efficiency is improved.

The connecting plate 11 can be made of any suitable material, and the scraper must be made of a material allowed by the specification.

When the paving scraper structure provided by this embodiment is used, the scraper body 21 is inserted into the first tongue-and-groove 111 on the connecting plate 11, so that the first mounting hole 112 is opposite to the second mounting hole 213, and the fillet 211 and the handle 14 are ensured to be arranged diagonally. The bolt is inserted through the first mounting hole 112 and the second mounting hole 213 and is fastened by a nut. The holding part is held, and the scraping part 22 is used for scraping the plane area of the part, so that the purpose of flattening and paving is achieved; compacting the R-angle edge line-shaped part by using the sharp corner part; the rounded portion 211 is used to compact the R-angle rounded portion. Structural design is reasonable, and it is convenient to use, spreads to paste efficiently, and the compaction is effectual to it is convenient to snatch, can the wide application take bent angle characteristic structure's combined material part production on a large scale. Simple structure, low processing difficulty, low investment cost and repeated use.
