Description

Technical Field

[0001] This utility model provides a notched scraper for tiling, belonging to the field of tile laying technology. Background Technology

[0002] Tiles are a common building material. Currently, the semi-dry and wet method is mainly used for laying floor tiles. When laying tiles, a notched scraper, such as a notched trowel, is usually needed. This scraper has protruding teeth on the edge and is commonly used for laying tiles. When laying tiles, hold the notched trowel and use the notched trowel to comb and smooth the tile mortar applied to the floor or wall.

[0003] Existing notched trowels for tiling can generally meet normal usage needs. After a tile is laid, the worker uses the notched trowel to smooth the tile mortar applied around the tile. However, considering the varying tiling skills of workers and fatigue from prolonged work, the downward pressure applied when moving the notched trowel back and forth can vary, inevitably resulting in unevenness of the notched teeth. This easily leads to significant height discrepancies between the subsequently laid tiles and adjacent tiles, posing a risk of tile removal and re-laying, and the tiling effect needs improvement. Therefore, this utility model provides a notched trowel for tiling. Utility Model Content

[0004] The technical problem solved by this utility model is that when the serrated trowel is held and moved back and forth, the downward pressure is often different, resulting in unevenness of the comb teeth. This can lead to a large height difference between the tile that is subsequently laid and the adjacent tile that has already been laid, which may pose a risk of the tile being removed and re-laid. The tile laying effect needs to be improved.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a toothed scraper for applying tiles, including a tile suction cup, with a pressure rod rotatably connected to the top of the tile suction cup; a support plate is ball-jointed to one side of the top of the tile suction cup, the top of the support plate is provided with a level bubble, and the two ends of the support plate are symmetrically provided with support feet for adjusting the level of the support plate; a sliding groove is provided on the side wall of the support plate away from the tile suction cup, and a slider is slidably connected in the sliding groove, with a toothed scraper placed on one side of the tile suction cup on the side wall of the slider.

[0006] Furthermore, the support foot includes a threaded rod that is threadedly connected to the support plate, the top of the threaded rod is provided with a handle, and the bottom of the threaded rod is rotatably connected to a pressure plate placed below the support plate.

[0007] Furthermore, the top side of the ceramic tile suction cup is provided with a ball seat, the bottom center of the support plate is provided with a support rod, and the bottom of the support rod is provided with a universal ball that matches the ball seat.

[0008] Furthermore, the slider sidewall is provided with reinforcing ribs that are fixedly connected to the toothed scraper sidewall.

[0009] Furthermore, the toothed scraper has a hand grip groove on the upper end of its side wall, and an anti-slip protrusion on the top of the toothed scraper is positioned above the hand grip groove.

[0010] Furthermore, the bottom and top of the groove are provided with limiting rails that match the slider.

[0011] The beneficial effects of this utility model are:

[0012] The device is fixed to the tile using a tile suction cup. The support feet are operated to move the support rod to a horizontal position. The toothed scraper is held and moved back and forth to comb and smooth the tile mortar. The toothed scraper does not have uneven downward pressure when moving back and forth, and the teeth are more even. This effectively avoids large height differences between the tile to be laid and the adjacent tile, reduces the risk of removing and re-laying the tile, and results in a better tiling effect.

Specifically, the worker's four fingers pass through the hand groove 8 and press on the anti-slip protrusion 16, and the thumb presses on the upper part of the toothed scraper 6. Moving the toothed scraper 6 back and forth can comb and scrape the tile mortar applied to the ground and wall.

[0024] The principle of this utility model

[0025] In use, the tile suction cup 1 is fixed to the surface of the tile by bending the pressure rod 7, thus preventing the slide 4 from moving back and forth. The support foot 3 is operated to move the support rod 13 to a horizontal position, thus fixing the position of the slide 4. Then, the toothed scraper 6 is held and moved back and forth to comb and smooth the tile mortar applied to the ground and wall. Compared with using a notched trowel, the toothed scraper 6 does not have different downward pressure when moving back and forth, and the teeth are more even. This effectively avoids large height differences between the tile to be applied and the adjacent tile, reduces the risk of removing and re-applying the tile, and results in a better tile application effect.
