Description

Technical Field

[0001] The utility model relates to the field of building decoration equipment, in particular to a roller brush for building decoration. Background Art

[0002] During the construction process of wall painting, using a roller brush for operation is a common and widely used method. However, there has always been a technical problem that cannot be ignored. That is, when operating the roller brush for painting, due to its edge being relatively hard and sharp and lacking an effective buffering or protection design, the edge part is often prone to scratching the adjacent wall surface.

[0003] This situation is particularly prominent in some specific scenarios. For example, when the distance between adjacent wall surfaces is relatively narrow, or when painting at positions such as corners or along the walls, it is difficult for construction workers to accurately control the distance between the roller brush and the adjacent wall surface, resulting in the inevitable collision and friction between the edge of the roller brush and the adjacent wall surface. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a roller brush for building decoration with a simple structure and effective protection for adjacent wall surfaces.

[0005] The utility model is realized by the following measures:

[0006] A roller brush for building decoration, characterized in that it includes a support rod, one end of the support rod is provided with a handle, the other end is provided with a round shaft, a roller is rotatably arranged around the round shaft, and bristles are arranged around the roller;

[0007] A groove one is arranged on one side end surface of the roller close to the free end of the round shaft, and a protection mechanism one is arranged in the groove one;

[0008] The protection mechanism one includes a disc one, the disc one is arranged on the periphery of the round shaft in the groove one through a threaded structure, and a number of groups of support parts one are evenly arranged in a circumferential array on the outer side surface of the disc one.

[0009] The specific characteristics of the utility model also include:

[0010] The support part one includes a column one arranged on the disc one, an arc groove one is arranged at the top end of the column one, a matching ball is movably placed in the arc groove one, a round tube is sleeved around the column one through a threaded structure, an arc groove two matched with the ball is arranged at the upper end inside the round tube, an opening for exposing a part of the structure of the ball is arranged above the arc groove two, and the ball can roll in the space formed by the arc groove one and the arc groove two and the exposed part of the opening can abut against the nearby side wall surface to prevent the wall surface from being scratched by the outer edge of the roller;

[0011] When it is necessary to use the first protective mechanism as a support for protection, the first disc can be rotated by turning the round tube by hand, so that it moves outward until the first support part extends out of the first groove. When not in use, the first disc can be rotated to move it inward, so that the entire first protective mechanism is received in the first groove.

[0012] A rubber pad is arranged on the outer side surface of the ball.

[0013] A limit cap is screwed on the free end of the round shaft. During the process of rotating the first disc outward, the limit cap plays a limiting role to prevent the first disc from detaching from the round shaft.

[0014] A second groove is arranged on the other end surface of the roller away from the first groove. A second protective mechanism with the same structure as the first protective mechanism is arranged in the second groove. The second protective mechanism includes a second disc corresponding to the first protective mechanism and several groups of second support parts. The second disc is arranged around the round shaft in the second groove through a threaded structure.

[0015] A first threaded hole is arranged on the outer side surface of the second disc. A countersunk head hole is arranged on the corresponding support rod. An internal hexagonal bolt matched with the first threaded hole is arranged in the countersunk head hole. The end of the internal hexagonal bolt passes through the countersunk head hole and is arranged in the first threaded hole. Since it is not convenient to arrange threads near the bent part of the support rod, the second disc is fixed by the internal hexagonal bolt. When it is necessary to use the second protective mechanism, first rotate the second disc close to the support rod until the second support part extends out of the support rod, and then fix the second disc by the internal hexagonal bolt. The second support part abuts against the nearby side wall to prevent the support rod from scratching the wall surface during the painting process. When the second protective mechanism is not in use, it can be received in the second groove.

[0016] A second threaded hole is arranged on the end surface of the round shaft where the support rod is arranged. A threaded rod matched with the second threaded hole is arranged on the corresponding end surface of the support rod. The threaded rod is arranged in the second threaded hole. The support rod is connected together through the cooperation of the threaded rod and the second threaded hole. Such a structure can facilitate the installation and disassembly of the second protective mechanism.

[0017] The beneficial effects of the present utility model are as follows: The structure of the present roller brush is simple and the operation is convenient. By arranging protective mechanisms at both ends, the problem of scratching the wall surface caused by the difficulty in controlling the distance from the adjacent wall surface during the wall painting process is effectively avoided.
