Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a roller brush for decoration and renovation. Background Art

[0002] Roller brush, also known as roller, is divided into three types: long-hair, medium-hair and short-hair. It is a tool used for rolling paint on large areas. Roller brushes are often used when rolling paint on large areas in interior decoration. During decoration, it is necessary to paint the surfaces of walls, ceilings and gypsum board ceilings.

[0003] The current roller brush is fixed, and the angle between the handle and the roller brush is relatively fixed. When painting the inner edge of the circular roof, it is necessary to raise the hand to keep the handle and the roller brush on the same horizontal plane for painting. Raising the hand for a long time will cause arm soreness, and when painting a large circular roof, it will cause excessive fatigue to the workers. Utility Model Content

[0007] In order to facilitate the removal of the first nut, further, the first nut is symmetrically provided with connecting ears.

[0008] Preferably, an extension rod is threadedly connected to the lower side of the handle.

[0009] In order to facilitate the limiting of the handle, the adjusting plate and the rotating plate, the connecting plate is further provided with a plurality of first limiting grooves in a circumference, the rotating plate is provided with a plurality of second limiting grooves, and the adjusting plate is symmetrically provided with a plurality of limiting rods arranged in a circumference, and the first limiting grooves and the second limiting grooves are both matched with the limiting rods.

[0010] In order to facilitate the replacement of the brush body, further, the brush body is detachably connected to the fixing rod, and a second nut is threadedly connected to one end of the fixing rod away from the fixing plate.

[0011] In order to ensure the smoothness of the brush body's rotation, further, the fixing rod is fixedly connected to one end close to the second nut with a rubber ring, the fixing rod is provided with a bearing matching the rubber ring, and the outer edge of the bearing abuts against the brush body, and the inner edge of the bearing abuts against the second nut.

[0012] Compared with the prior art, the utility model provides a roller brush for decoration and renovation, which has the following beneficial effects:

[0013] 1. The roller brush for decoration and renovation rotates the first nut through the connecting ear, and then adjusts the angle between the handle, the adjustment plate and the rotating plate to make the handle and the brush body form a certain angle. The best adjustment position can make the handle parallel to the brush body, so as to facilitate the painting of the inner edge of the circular top, effectively preventing the staff from over-fatigue due to long-term lifting of hands for painting.

[0014] 2. The decorative roller brush cooperates with the limiting rod through the first limiting groove and the second limiting groove, and the limiting rod close to the first circular hole is engaged in the first limiting groove, and the limiting rod close to the third circular hole is engaged in the second limiting groove, thereby effectively limiting the handle, the adjustment plate and the rotating plate to prevent the brush body from shifting and shaking during the painting operation and affecting its painting operation.

[0015] 3. The roller brush for decoration and renovation can limit the brush body and ensure the smooth rotation of the brush body through the setting of the bearing, thereby effectively improving the effect of painting and making the painting more labor-saving.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model makes it easy to brush paint on the inner edge of the circular top, effectively preventing the staff from over-fatigue due to long-term lifting of hands for brushing, and effectively preventing the brush body from shifting and shaking during the painting operation, affecting the painting operation.

DETAILED DESCRIPTION

[0024] 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.

[0025] Example 1: Reference Figure 1-Figure 6 A roller brush for decoration and renovation comprises: a handle 1, and also comprises: a connecting plate 101 fixed at one end of the handle 1; a first circular hole 102 opened on the connecting plate 101; an adjusting plate 2 rotating on one side of the connecting plate 101; a second circular hole 201 symmetrically arranged on the adjusting plate 2; a rotating plate 3 rotating on the end of the adjusting plate 2 away from the connecting plate 101; a third circular hole 301 opened on the rotating plate 3; a fixed plate 303 fixed at the end of the rotating plate 3 away from the adjusting plate 2; a fixing rod 304 fixed on the fixing plate 303; a brush body 307 rotatably arranged on the fixing rod 304; a bolt 203 arranged in the second circular hole 201; and a first nut 204 threadedly connected to the bolt 203.

[0026] The first nut 204 is symmetrically provided with connecting ears 205 .

[0027] An extension rod 104 is threadedly connected to the lower side of the handle 1 .

[0028] When painting the indoor wall, the brush body 307 is placed in a bucket for storing paint outside to dip the paint, and then the handle 1 or the installed extension rod 104 is held to paint the wall. When painting the inner edge of the circular roof, the first nut 204 is rotated through the connecting ear 205, and then the angle between the handle 1, the adjustment plate 2 and the rotating plate 3 is adjusted to make the handle 1 and the brush body 307 form a certain angle. The best adjustment position can make the handle 1 parallel to the brush body 307, so as to facilitate painting the inner edge of the circular roof, and effectively prevent the staff from over-fatigue due to long-term lifting of hands for painting.

[0029] Example 2: Reference Figure 1-Figure 6 A roller brush for decoration and renovation is basically the same as Example 1. Further, a connecting plate 101 is circumferentially provided with a plurality of first limiting grooves 103, a rotating plate 3 is provided with a plurality of second limiting grooves 302, and an adjusting plate 2 is symmetrically provided with a plurality of limiting rods 202 arranged in a circle, and the first limiting grooves 103 and the second limiting grooves 302 are matched with the limiting rods 202.

[0030] The brush body 307 is detachably connected to the fixing rod 304 , and a second nut 306 is threadedly connected to one end of the fixing rod 304 away from the fixing plate 303 .

[0031] A rubber ring 305 is fixedly connected to one end of the fixing rod 304 close to the second nut 306 , and a bearing 4 matching the rubber ring 305 is arranged on the fixing rod 304 , and the outer edge of the bearing 4 abuts against the brush body 307 , and the inner edge of the bearing 4 abuts against the second nut 306 .

[0032] When adjusting the angles of the handle 1, the adjustment plate 2 and the rotating plate 3, the first limit groove 103 and the second limit groove 302 cooperate with the limit rod 202, and the limit rod 202 close to the first circular hole 102 is engaged in the first limit groove 103, and the limit rod 202 close to the third circular hole 301 is engaged in the second limit groove 302, thereby effectively limiting the handle 1, the adjustment plate 2 and the rotating plate 3 to prevent the brush body 307 from shifting and shaking during the painting operation and affecting its painting operation.

[0033] By setting the bearing 4, the brush body 307 can be limited and the smooth rotation of the brush body 307 can be ensured, thereby effectively improving the effect of brushing paint and making the brushing more labor-saving.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
