Description
Technical Field
[0001] This utility model relates to the technical field of base treatment devices, and in particular to a base treatment device. Background Technology
[0002] A brush roller is a device used for painting walls. It is often used for base treatment of walls. The brush roller is dipped in treatment liquid and brushed onto the wall for base treatment.
[0003] The inventors discovered during daily use of brush rollers that, since brush rollers are generally fixed to the surface of the roller frame, they cannot be removed and replaced when damaged. This prevents the roller frame from being recycled, resulting in economic waste and other negative consequences. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a base treatment device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a base treatment device, including a handle, a brush handle fixedly connected to one end of the handle, a brush rod rotatably connected to the surface of the brush handle, a brush roller provided on the surface of the brush rod, a replacement device provided on the surface of the brush rod, an anti-drip device provided on the surface of the brush rod, the replacement device including a circular groove formed inside the brush rod, a screw rotatably connected inside the circular groove, a pressing block threadedly connected to the surface of the screw, a fixing rod fixedly connected to the inner wall of the circular groove, the pressing block slidably connected to the surface of the fixing rod, a rectangular rod slidably connected to the surface of the brush rod, and an arc-shaped plate fixedly connected to one end of the rectangular rod.
[0006] The effect achieved by the above components is as follows: under the action of the extrusion block and the rectangular rod, the position of the arc plate can be adjusted, thereby fixing the brush roller on the surface of the brush rod, thus achieving the function of replacing the brush roller. When it is necessary to treat the base layer of the wall, the brush handle and the handle are fixed together, the brush roller is fixed on the surface of the brush rod through the replacement device, the brush roller is immersed in the treatment liquid, and the base layer is treated by brushing the brush rod on the wall.
[0007] Preferably, a pad, which is a rubber block, is fixedly connected to the surface of the extrusion block.
[0008] The effect achieved by the above components is that, under the action of the pad, the extrusion block will not directly contact the rectangular rod, thus avoiding damage caused by direct impact.
[0009] Preferably, the surface of the arc-shaped plate is fixedly connected with an anti-slip strip, which is a rubber strip.
[0010] The effect achieved by the above components is that, under the action of the anti-slip strip, the brush roller will not slip off the surface of the curved plate.
[0011] Preferably, an elastic rope is fixedly connected to the inner wall of the arc-shaped plate, and the other end of the elastic rope is fixedly connected to the surface of the brush rod.
[0012] The effect achieved by the above components is that, under the action of the elastic rope, the arc plate can be reset after the extrusion block separates from the rectangular rod, thus facilitating the replacement of the brush roller.
[0013] Preferably, one end of the screw is provided with a locking rod, and the side of the brush rod is provided with a groove, with the locking rod inserted into the inside of the groove.
[0014] The aforementioned components achieve the following effects: Under the action of the locking lever, the screw can be limited after rotating to a suitable position, preventing the screw from rotating. When it is necessary to replace the brush roller, rotating the screw causes the extrusion block to separate from the rectangular rod, and then the arc plate is reset under the action of the elastic rope, thereby removing the brush roller. The new brush roller is then placed on the surface of the arc plate, and the screw is turned so that the extrusion block presses against the rectangular rod, thereby pushing the arc plate outward and fixing the brush roller on the surface of the brush rod. Under the action of the anti-slip strip, the brush roller will not slip off the surface of the arc plate. When the arc plate moves to a suitable position, the locking lever limits and fixes the screw, thus achieving the purpose of replacing the brush roller.
[0015] Preferably, the anti-drip device includes a retaining ring sleeved on the surface of the brush rod, a collection frame fixedly connected to the bottom of the retaining ring, and a magnetic block fixedly connected to the surface of the retaining ring, the magnetic block being magnetically connected.
[0016] The effect achieved by the above components is that, under the action of the magnetic block, the retaining rings can be fixed together, thereby fixing the collection frame to the bottom of the brush rod, thus achieving the function of fixing the collection frame.
[0017] Preferably, the surface of the brush rod is provided with a groove, and a ball bearing is rotatably connected inside the groove.
[0018] The effect achieved by the above components is that the retaining ring can rotate under the action of the ball bearings, thereby preventing the brush roller from dripping.
[0019] Preferably, a bolt is inserted into the surface of one retaining ring, and a nut is fixedly connected to the surface of the other retaining ring, with the bolt and nut being threadedly connected.
[0020] The effect achieved by the above components is as follows: under the action of bolts and nuts, the retaining ring can be locked onto the surface of the brush rod. When it is necessary to prevent the treatment liquid on the surface of the brush roller from dripping, the retaining ring sleeve and magnetic blocks are attracted together, the bolt is inserted into the inside of the nut, and the retaining ring is fixed on the surface of the brush rod. Under the action of the ball bearings, the retaining ring can rotate, thereby preventing the brush roller from dripping, thus achieving the effect of preventing dripping.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, a replacement device is provided. When the brush roller needs to be replaced, the screw is rotated to separate the extrusion block from the rectangular rod. Then, under the action of the elastic rope, the arc plate is reset, thereby removing the brush roller. The new brush roller is then placed on the surface of the arc plate. The screw is turned so that the extrusion block presses against the rectangular rod, thereby pushing the arc plate outward and fixing the brush roller on the surface of the brush rod. With the help of the anti-slip strip, the brush roller will not slip off the surface of the arc plate. When the arc plate moves to the appropriate position, the screw is limited and fixed by the action of the locking rod, thus achieving the purpose of replacing the brush roller. This solves the problem that the lights on the surface of the corridor lighting equipment cannot be removed in an emergency. Attached Figure Description
