[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A building wall painting device, such as Figure 1-5 As shown, it includes a roller brush 100, the interior of the roller brush 100 is penetrated by a support rod 110, the bottom end of the support rod 110 is fixedly connected to an inner rod 120, the outer wall of the inner rod 120 is sleeved with an outer rod 130, an adjusting groove 141 is opened inside the outer rod 130, the outer wall of the outer rod 130 is connected to a rotating knob 140 that penetrates the adjusting groove 141, a steel wire rope 142 is wound around the outer wall of the rotating knob 140, the other end of the steel wire rope 142 is fixedly connected to a clamping column 145, a limiting wheel 143 is assembled at the position where the inner corner of the adjusting groove 141 and the steel wire rope 142 fit together, and the bottom end of the clamping column 145 is located inside the adjusting groove 141 and is fixedly connected to a spring 144.

[0024] A rotation groove matching the rotation knob 140 is formed on the outer wall of the outer rod 130 , and the rotation groove and the rotation knob 140 are rotationally connected.

[0025] The front and rear side walls of the inner rod 120 are provided with a clamping slot 122 , and the size of the clamping slot 122 matches the size of the clamping column 145 .

[0026] A plurality of groups of the locking slots 122 are equidistantly formed on the front and rear side surfaces of the inner rod 120 .

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 When the use length of the coating device needs to be adjusted, the rotary knob 140 can be rotated. When the rotary knob 140 is rotated, the wire rope 142 can be driven to reel in. The wire rope 142 is wound around the outer wall of the rotary knob 140 for reeling in. When the wire rope 142 is reeled in, the limiting wheel 143 can be driven to rotate. At the same time, the wire rope 142 can be guided and can also play a limiting role. At this time, the wire rope 142 can be used to work the clamping column 145 to move. When the clamping column 145 moves, its end can squeeze the spring 144, so that the clamping column 145 is squeezed into the inside of the adjustment groove 141, so that the clamping column 145 is separated from the clamping groove 122, and then the inner rod 120 can be pulled to move and adjust. When it moves to the specified position, the rotary knob 140 can be rotated in the opposite direction to cooperate with the limiting wheel 143, so that the clamping column 145 is reset and engaged through the elasticity of the spring 144 itself, so that the adjustment work can be completed.

[0028] Slide blocks 131 are fixedly connected to both sides of the inner side wall of the outer rod 130 , and sliding grooves 121 are formed on both sides of the outer side wall of the inner rod 120 .

[0029] The size of the slide groove 121 is opened at a position slightly below the two side surfaces of the inner rod 120 , and the outer rod 130 is slidably connected to the slide groove 121 via the slider 131 .

[0030] A protective sleeve is connected to the joint position between the support rod 110 and the inner rod 120, and the protective sleeve is made of soft rubber material.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 When the inner rod 120 and the outer rod 130 slide to adjust the height, the slider 131 can slide inside the slide groove 121. Since the length of the slide groove 121 is limited, the inner rod 120 can be prevented from being completely pulled out when sliding, which affects the adjustment efficiency of the application rod. A protective cover is provided at the docking position between the support rod 110 and the inner rod 120. The staff can hold the protective cover part when using it, which can provide a certain protection for the staff's hands.

[0032] When in use, the height of the application rod can be adjusted as needed, and the rotating knob 140 can be turned. When the rotating knob 140 is turned, the wire rope 142 can be driven to be retracted, and the wire rope 142 is wound around the outer wall of the rotating knob 140 for retraction. When the wire rope 142 is retracted, it can drive the limiting wheel 143 to rotate, and at the same time, the wire rope 142 can be guided and can also play a role of limiting. At this time, the clamping column 145 can be moved by the wire rope 142. When the clamping column 145 moves, its end can squeeze the spring 144, so that the clamping column 145 is squeezed into the inside of the adjustment groove 141, so that the clamping column 145 is separated from the clamping groove 122, and then the inner rod 120 can be pulled to move and adjust. When moved to the specified position, the reverse rotation of the rotating knob 140 can cooperate with the limiting wheel 143, so that the clamping column 145 can be reset and engaged through the elasticity of the spring 144. When the inner rod 120 and the outer rod 130 slide to adjust the height, the slider 131 can slide inside the slide groove 121. Since the length of the slide groove 121 is limited, the inner rod 120 can be prevented from being completely pulled out when it is pulled out and sliding, affecting the adjustment efficiency of the application rod. In this way, the adjustment work can be completed. A protective cover is provided at the docking position between the support rod 110 and the inner rod 120. The staff can hold the protective cover part when using it, which can provide a certain protection for the staff's hands.
