Description

Technical Field

[0001] The utility model relates to the technical field of wall painting brushes, in particular to a wall painting brush for building construction. Background Art

[0002] With the continuous development of the economy, people's requirements for the living environment are getting higher and higher, and the pursuit of decoration quality is also getting higher and higher. In the process of decoration, the use of wall painting brushes is essential. When the wall painting brush is used to paint the wall, it is necessary to dip the paint from the paint bucket. If too much paint is dipped during the painting process, it is easy to drip on the ground and is inconvenient to clean. Therefore, a wall painting brush that can avoid the paint dripping on the ground is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a wall painting brush for building construction, effectively solving the deficiencies of the prior art.

[0004] The purpose of the utility model is achieved by the following technical solutions: A wall painting brush for building construction, including a wall painting rod, the top of the wall painting rod is fixedly connected with a connecting rod, the end of the connecting rod is rotatably connected with a wall painting roller, the end of the connecting rod is rotatably connected with a rotating ring, the bottom of the rotating ring is rotatably connected with a rotating shaft, the rotating ring is rotatably connected with a material receiving plate through the rotating shaft, and a torsion spring is sleeved on the middle part of the rotating shaft.

[0005] Optionally, the connecting rod is bent outward, and the axis of the wall painting rod is vertically crossed with the axis of the wall painting roller.

[0006] Optionally, the cross-sectional shape of the material receiving plate is an arc surface, the length of the material receiving plate is greater than the length of the wall painting roller, and the thickness of the rear side of the material receiving plate is less than the thickness of the front side of the material receiving plate.

[0007] By adopting the above technical solutions: By arranging an arc-shaped material receiving plate at the end of the connecting rod, under the action of gravity, the material receiving plate is kept below the wall painting roller. When the paint drips during the painting of the wall painting roller, it can be received by the material receiving plate, thus avoiding the situation that the paint drips on the ground or on the lower painters and is inconvenient to clean. Limiting the different thicknesses on both sides of the material receiving plate makes the center of gravity of the material receiving plate located on the side with a thicker thickness, so that the material receiving plate tilts backward under the action of gravity, avoiding the situation that the material receiving plate affects the painted wall.

[0008] Optionally, the torsion of the torsion spring makes the material receiving plate parallel to the wall painting roller, and the torsion of the torsion spring is greater than the gravity of the material receiving plate.

[0009] The above technical solution is adopted: by arranging a torsion spring in the middle of the rotating shaft, the receiving plate can be kept below the wall plastering roller under the action of torsion to receive the dripping paint. When the wall plastering roller is inserted into the paint barrel to dip the paint, the receiving plate can be rotated to stagger it with the wall plastering roller, thereby preventing the wall plastering roller from entering the paint barrel and attaching a large amount of paint, causing material waste.

[0010] Optionally, the friction coefficient between the rotating ring and the connecting rod is less than 0.5, the bottom of the rotating ring extends downward, and the extended part of the rotating ring is rotatably connected to the rotating shaft.

[0011] Optionally, a slot is provided on the top of the wall plaster rod, a pull rope is fixedly connected to the bottom of one end of the receiving plate, a connecting portion between the pull rope and the receiving plate is located on a side away from the rotating shaft, and the pull rope passes through the slot.

[0012] The above technical solution is adopted: by setting a pull rope at the bottom of the receiving plate, when it is necessary to immerse the wall plastering roller into the paint barrel, the pull rope can be pulled to rotate the receiving plate downward and staggered with the wall plastering roller. When holding the wall plastering rod, the receiving plate can be conveniently rotated and staggered to prevent it from entering the paint barrel and being contaminated by paint.

[0013] Optionally, both ends of the slot are provided with rounded corners, and the friction coefficient between the slot and the pull rope is less than one.

[0014] Optionally, a fixed handle is fixedly connected to the bottom of the wall plastering rod, a movable handle is slidably connected to the middle of the wall plastering rod, the top of the movable handle is fixedly connected to the pull rope, and the top of the fixed handle and the bottom of the movable handle are adsorbed by magnets.

[0015] The above-mentioned technical solution is adopted: by arranging a fixed handle and a movable handle at the bottom of the wall plastering rod, it is convenient for the operator to hold the wall plastering rod to perform wall plastering operations, and the movable handle can be slid downward to rotate the material receiving plate downward and staggered with the wall plastering roller, so that the wall plastering roller can enter the paint barrel to dip the material alone, and the movable handle that slides downward can fix its movable handle and the material receiving plate in this state through the magnetic attraction relationship with the fixed handle, thereby avoiding the material receiving plate from interfering with the wall plastering roller when unnecessary.

[0016] The utility model has the following advantages:

[0017] 1. The wall plastering brush for building construction has an arc-shaped receiving plate at the end of the connecting rod. The receiving plate is kept below the wall plastering roller under the action of gravity. When the wall plastering roller drips paint during painting, it can be received by the receiving plate, thereby preventing the paint from dripping on the ground or on the painter below, which is inconvenient to clean up. The thickness of both sides of the receiving plate is different, so that the center of gravity of the receiving plate is located on the thicker side, so that the receiving plate is tilted backward under the action of gravity, thereby preventing the receiving plate from affecting the painted wall surface.

[0018] 2. The wall plastering brush for building construction has a torsion spring arranged in the middle of the rotating shaft, so that the receiving plate can be kept below the wall plastering roller under the action of torsion to receive dripping paint. When the wall plastering roller is inserted into the paint barrel to dip in paint, the receiving plate can be rotated to be staggered with the wall plastering roller to avoid the wall plastering roller entering the paint barrel and attaching a large amount of paint to cause material waste. A pull rope is arranged at the bottom of the receiving plate, when the wall plastering roller needs to be dipped into the paint barrel, the pull rope can be pulled to rotate the receiving plate downward to stagger it with the wall plastering roller. When the wall plastering rod is held, the receiving plate can be conveniently rotated to be staggered to avoid it entering the paint barrel and being contaminated by paint.

[0019] 3. The wall plastering brush for construction is convenient for the operator to hold the wall plastering rod for wall plastering operations by arranging a fixed handle and a movable handle at the bottom of the wall plastering rod, and the movable handle can be slid downward to rotate the material receiving plate downward to stagger the wall plastering roller, so that the wall plastering roller can enter the paint barrel and dip the material alone, and the movable handle that slides downward can fix the movable handle and the material receiving plate in this state through the magnetic attraction relationship with the fixed handle, so as to avoid the material receiving plate from interfering with the wall plastering roller when unnecessary.
