[0004] When the roller brush is used for painting, there is no object to be received under the paint roller, so a large amount of paint may fall directly on the ground during painting. The paint falling on the ground is not only troublesome to clean up, but also causes certain waste. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a roller brush for construction engineering, which can collect dripping paint and avoid the problem of paint falling on the ground and being troublesome to clean up. At the same time, the paint falling into the receiving trough can be reused to avoid waste.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A roller brush for construction engineering comprises a roller and a brush rod, wherein a material receiving groove is arranged below the roller, and two connecting rods are fixedly connected to the upper surface of the material receiving groove, and a clamping groove is opened on one side wall of the two connecting rods, and the brush rod is arranged inside the clamping groove.

[0008] Preferably, a clearance groove is provided on the inner wall of the clamping slot, and a ball is arranged in the clearance groove, and a side wall of the ball is against the brush rod.

[0009] Preferably, the upper end of the connecting rod is provided with an oblique chamfer.

[0010] Preferably, a semi-annular groove is formed on one side wall of the connecting rod.

[0011] Preferably, a threaded hole is formed on one side wall of the two connecting rods, and a threaded rod is threadedly connected to the inner wall of the threaded hole. The thread directions of the two threaded rods are opposite, and the two threaded rods are fixedly connected to each other.

[0012] Preferably, one end of one of the threaded rods is fixedly connected to a rotating block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model is used in conjunction with the connecting rod and the material receiving trough, etc., and the material receiving trough can be hung under the roller when in use. In this way, when painting, dripping paint can fall into the material receiving trough and be received by the material receiving trough, which not only avoids the problem of paint falling on the ground and being troublesome to clean up, but also the paint fallen in the material receiving trough can be reused, thus avoiding waste. The material receiving trough is hung on the outer wall of the brush rod instead of being directly fixed on the brush rod. When painting, due to the weight of the material receiving trough, it can be ensured that the material receiving trough is always under the roller to ensure the receiving of the material receiving trough; and the material receiving trough etc. can be directly removed, and then after the roller and the brush rod are damaged during use, the material receiving trough can be removed and replaced with a roller brush composed of another roller and brush rod, thereby saving costs.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 4 A roller brush for construction engineering includes a roller 1 and a brush rod 2. A material receiving groove 3 is arranged below the roller 1. The width of the material receiving groove 3 is much smaller than the diameter of the roller 1 to ensure that the material receiving groove 3 will not contact the wall when the roller 1 is painting. Two connecting rods 4 are fixedly connected to the upper surface of the material receiving groove 3. A card slot 5 is opened on one side wall of the two connecting rods 4, and the brush rod 2 is arranged inside the card slot 5.

[0022] It can be seen from the above structure that: by setting the connecting rod 4 and the material receiving trough 3 for use in conjunction with the same, when in use, the material receiving trough 3 can be hung under the roller 1, so that when painting, the dripping paint can fall into the material receiving trough 3 and be received by the material receiving trough 3, which not only avoids the problem of paint falling on the ground and being troublesome to clean up; at the same time, the paint falling in the material receiving trough 3 can also be reused, avoiding waste, and the material receiving trough 3 is hung on the outer wall of the brush rod 2, instead of being directly fixed on the brush rod 2. When painting, due to the weight of the material receiving trough 3, it can be ensured that the material receiving trough 3 is always under the roller 1 to ensure the receiving of the material receiving trough 3; and the material receiving trough 3 can be directly removed, and then after the roller 1 and the brush rod 2 are damaged during use, the material receiving trough 3 can be removed, and the material receiving trough 3 can be replaced with a roller brush composed of another roller 1 and brush rod 2, thereby saving costs.

[0023] See also Figure 3 and Figure 4 A clearance groove is provided on the inner wall of the card slot 5, and a ball 6 is arranged in the clearance groove, and one side wall of the ball 6 is against the brush rod 2; by arranging the ball 6, the friction between the connecting rod 4 and the brush rod 2 can be reduced to ensure that when the brush rod 2 is deflected, the connecting rod 4 and the material receiving groove 3 will not deflect with the brush rod 2 due to friction.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper end of the connecting rod 4 is provided with an oblique chamfer; by providing the oblique chamfer, when the brush rod 2 is inserted into the slot 5, it is convenient to press the brush rod 2 into the slot 5 through the oblique chamfer.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A semi-annular groove 7 is provided on one side wall of the connecting rod 4; by providing the semi-annular groove 7, the strength of the connecting rod 4 can be reduced, thereby facilitating the deformation of the connecting rod 4.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, a threaded hole 8 is opened on one side wall of the two connecting rods 4, and a threaded rod 9 is threadedly connected to the inner wall of the threaded hole 8, the thread directions of the two threaded rods 9 are opposite, and the two threaded rods 9 are fixedly connected to each other; by setting two threaded rods 9, and the threads of the two threaded rods 9 are opposite, when the threaded rods 9 are rotated, the rotating threaded rods 9 can drive the two connecting rods 4 to move away from or approach each other. When the two connecting rods 4 move away from each other, the brush rod 2 can be easily removed from the slot 5. When the two connecting rods 4 are close to each other, it is difficult to remove the brush rod 2 from the slot 5.

[0027] See also Figure 3 and Figure 4 One end of one threaded rod 9 is fixedly connected to a rotating block 10; by setting the rotating block 10, when the threaded rod 9 is rotated, the rotating block 10 can be rotated.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
