Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, in particular to a wall scraping tool for building decoration. Background Art

[0002] At present, in the process of house decoration, wall scraping tools are needed to remove the bulges or the entire old paint layer on the wall to facilitate repainting the wall and avoid the old paint layer not being removed, resulting in bulging or falling off of the wall after painting.

[0003] Existing wall scraping tools for building decoration generally adopt scrapers. Common scrapers include a handle and a basically triangular or trapezoidal blade, which is used to scrape off the old plaster layer. However, the scraper has no height adjustment function and cannot flatten high walls. Workers need to use ladders to climb up, which is not only cumbersome to operate, but also increases the danger of workers during work, making it unsuitable for people to use.

[0004] To this end, we provide a wall scraping tool for building decoration to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a wall scraping tool for building decoration. By coordinating the adjustment component and the dust removal component, the utility model solves the problem that the wall scraping tool for building decoration in the prior art has no height adjustment function and requires workers to perform high-altitude operations when leveling high walls, which is very dangerous.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a wall scraping tool for building decoration, comprising a box body, an adjustment component and a dust removal component. The inner cavity of the box body is provided with a movable plate, the rear side of which is fixedly connected to a scraper, and both sides of the inner bottom of the box body are fixedly connected to electric push rods, and the top of the output end of the electric push rod is fixedly connected to the movable plate;

[0008] The adjustment assembly is arranged at the bottom of the box body, including a handle, an inner cavity of the handle is provided with a limit plate, the top of the limit plate is fixedly connected to a telescopic rod, the top of the telescopic rod passes through the handle and is fixedly connected to the box body, both sides of the telescopic rod are fixedly connected to tooth plates, a fixed opening is opened on the rear side of the handle, both sides between the top and bottom of the inner cavity of the fixed opening are movably connected to clamping plates, a spring is fixedly connected to the rear side between the two clamping plates, and teeth are fixedly connected to the front sides of the opposite sides of the two clamping plates, and the teeth are meshed with the tooth plates;

[0009] The dust removal assembly is arranged on the right side of the handle and includes a ventilation pipe. A filter element is fixedly connected between the two sides of the inner cavity of the ventilation pipe. A fan is fixedly connected to the bottom between the two sides of the inner cavity of the ventilation pipe. The top of the ventilation pipe is connected to the box body through a hose.

[0010] The present invention is further configured such that handles are fixedly connected to both sides of the grip, and a movable opening for use with a telescopic rod is provided on the top of the grip.

[0011] The utility model is further configured as follows: the scraper comprises a fixed frame and a blade, the blade is obliquely installed in the inner cavity of the fixed frame, and the bottom of the box body is connected to a discharge square pipe.

[0012] The utility model is further configured such that both sides of the top of the inner cavity of the box body are fixedly connected with sliding rods, the surface of the sliding rods is sleeved with sliding sleeves, and the rear side of the sliding sleeves is fixedly connected to the scraper.

[0013] The utility model is further configured such that a material guide block is fixedly connected to the front side of the bottom of the inner cavity of the box body, and the shape of the material guide block is triangular.

[0014] The utility model is further configured such that the left side of the ventilation pipe is fixedly connected to the handle via a mounting block, and the top and bottom of the splint are movably connected to the inner wall of the fixed opening via bearings.

[0015] The utility model is further configured such that both sides of the fan are fixedly connected with mounting rods, and a side of the mounting rod away from the fan is fixedly connected to the inner wall of the ventilation pipe.

[0016] The utility model is further configured such that a baffle is provided on the right side of the ventilation pipe, and the left side of the baffle is fixedly connected to the ventilation pipe by bolts.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model can push the two splints to squeeze the spring through the setting of the adjustment component. At the same time, the teeth fixed on the two splints no longer mesh with the tooth plate. Then the staff can pull out the telescopic rod to adjust the box body to the required use height. After loosening the splints, the spring resets, and the spring drives the two splints to move, so that the teeth fixed on the splints mesh with the tooth plate again, completing the adjustment of the use height of the box body. When leveling a high wall, there is no need for the staff to perform high-altitude operations.

[0019] 2. The utility model is provided with a dust removal component. When the scraper is leveling the wall, the fan is turned on to extract the air inside the box body through the fan, so that the wall dust is transported to the inner cavity of the ventilation pipe through the hose. The wall dust is filtered by the filter element to prevent the wall dust from flying around and affecting the health of the staff. The wall dust is stored inside the ventilation pipe, and the baffle can be opened to conduct centralized treatment after the wall surface is leveled.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
