Description

Technical Field

[0001] This utility model relates to the technical field of building wall plastering tools, specifically, to a wall plastering scraper with adjustable angle. Background Technology

[0002] In building decoration, wall plastering is a crucial process. Its purpose is to fill wall gaps, level the wall surface, and provide a good foundation for subsequent decoration work such as wallpapering and painting. Commonly used plastering tools usually include plastering scrapers.

[0003] Currently, most plastering scrapers on the market are fixed designs and cannot be adjusted according to the specific angle of the wall. This forces construction workers to frequently change tools or resort to manual adjustments when dealing with inside and outside corners of walls, which is not only inefficient but also makes it difficult to guarantee the quality of plastering. This is especially true when dealing with complex wall structures, such as the junction of brick and concrete walls, or the junction of different materials. Due to the differences in wall materials and the crack resistance requirements at the junction, traditional fixed plastering scrapers are simply insufficient to meet the construction needs. In view of this, we have proposed a wall plastering scraper with a finely adjustable angle. Utility Model Content

[0004] The purpose of this invention is to provide a wall plastering scraper with an adjustable angle to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-angle wall plastering scraper includes a plastering scraper body. A fixed base is fixedly installed on the upper surface of the plastering scraper body. A support is fixedly installed at the center of the upper surface of the fixed base. A handle is provided on the top of the support. An arc-shaped groove is provided in the bottom rod of the handle. Limiting plates are fixedly installed on both the left and right sides of the top rod of the support. The limiting plates are located in the arc-shaped groove and are rotatably connected to the left and right side walls of the arc-shaped groove through a rotating shaft. Multiple insertion limiting holes are provided on the annular side of the limiting plate in a ring-shaped and equally spaced manner. Two mutually symmetrical fastening screws are internally threaded to the handle. Insertion limiting rods are fixedly installed at the bottom ends of the fastening screws. The insertion limiting rods are inserted into the insertion limiting holes.

[0007] Preferably, both the insertion limiting rod and the insertion limiting hole have circular cross-sections, and the size of the insertion limiting rod is adapted to the size of the insertion limiting hole.

[0008] Preferably, two symmetrical studs are fixedly installed on the top surface of the plastering scraper body. The studs pass through the fixed base and are threaded with nuts.

[0009] Preferably, the fixed base has two symmetrical bolt holes on the left and right sides, the stud passes through the bolt holes, and the nut abuts against the upper surface of the fixed base.

[0010] Preferably, the plastering scraper body and the stud are integrally formed, and the fixed base and the support are integrally formed.

[0011] Preferably, a cap is fixedly installed at the top of the fastening screw, and a cross groove is provided inside the cap.

[0012] Preferably, the top of the handle has two symmetrical annular grooves, the bottom wall of the annular grooves has a threaded hole, the fastening screw is threadedly connected to the threaded hole, and the cap is located in the annular groove.

[0013] Preferably, the thickness of the cap is equal to the depth of the annular groove, and the number of insertion limiting holes on each limiting plate is 6 to 12.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a rotating connection between the support and the handle to allow the support and the main body of the plastering scraper to rotate, thereby adjusting the tilt angle of the main body of the plastering scraper. In addition, a plug-in limiting rod is inserted into the plug-in limiting hole to limit the position, so that the support will not easily rotate after being limited, achieving the effect of allowing for fine-tuning of the angle and fixing after adjustment.

[0016] 2. This utility model achieves the effect of conveniently fixing, installing, disassembling, and replacing the main body of the plastering scraper by passing the stud through the bolt hole and fixing it with a nut. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a wall plastering scraper with adjustable angle, including a plastering scraper body 1, a fixed base 2 fixedly installed on the upper surface of the plastering scraper body 1, a support 22 fixedly installed at the center of the upper surface of the fixed base 2, a handle 3 provided on the top of the support 22, an arc groove 30 provided in the bottom rod of the handle 3, and a limiting plate 23 fixedly installed on both the left and right sides of the top rod of the support 22. The limiting plate 23 is located in the arc groove 30 and is rotatably connected to the left and right sides of the arc groove 30 through a rotating shaft 25, so that the support 22 can rotate to realize the angle adjustment operation;

[0027] Specifically, the annular side of the limiting plate 23 is provided with multiple insertion limiting holes 24 arranged in a ring at equal intervals. The handle 3 is internally threaded with two symmetrical fastening screws 33. The bottom end of the fastening screws 33 is fixedly installed with an insertion limiting rod 35. The insertion limiting rod 35 is inserted into the insertion limiting hole 24 to realize the limiting and fixing operation of the support 22 after the angle is adjusted, so that the support 22 will not rotate easily.

[0028] In this embodiment, both the insertion limiting rod 35 and the insertion limiting hole 24 have circular cross-sections. The size of the insertion limiting rod 35 is adapted to the size of the insertion limiting hole 24 to stabilize the insertion assembly operation.

[0029] Specifically, two symmetrical studs 10 are fixedly installed on the top surface of the plastering scraper body 1. The studs 10 pass through the fixed base 2 and are threaded with nuts 21. The fixed base 2 has two symmetrical bolt holes 20. The studs 10 pass through the bolt holes 20 and the nuts 21 rest on the upper surface of the fixed base 2, so as to facilitate the fixed installation and disassembly and replacement of the plastering scraper body 1.

[0030] Furthermore, the plastering scraper body 1 and the stud 10 are integrally formed, and the fixed base 2 and the support 22 are integrally formed, ensuring that the overall structure is more solid and stable.

[0031] In addition, a cap 34 is fixedly installed on the top of the fastening screw 33. The cap 34 has a cross groove inside, which can be used with an external Phillips screwdriver for tightening.

[0032] It is worth noting that there are two symmetrical annular grooves 31 on the top of the handle 3. The bottom wall of the annular groove 31 is provided with threaded holes 32. The fastening screw 33 is threadedly connected to the threaded hole 32. The cap 34 is located in the annular groove 31. The thickness of the cap 34 is equal to the depth of the annular groove 31. The number of insertion limiting holes 24 on each limiting plate 23 is 6 to 12, so that the cap 34 can be hidden and stored in the annular groove 31.

[0033] When using the wall plastering scraper with adjustable angle of this utility model, the stud 10 is passed through the bolt hole 20, and then the nut 21 is tightened on the stud 10 to complete the assembly operation of the plastering scraper body 1. Loosen the fastening screw 33 so that the insertion limiting rod 35 is disengaged from the insertion limiting hole 24. At this time, the support 22 can be rotated. Rotating the support 22 can adjust the angle of the plastering scraper body 1. After the adjustment is completed, ensure that the corresponding insertion limiting hole 24 is still below the insertion limiting rod 35. Then, tighten the fastening screw 33 again so that the insertion limiting rod 35 is inserted into the insertion limiting hole 24 for limiting and fixing.
