Description

Technical Field

[0001] This utility model belongs to the field of decoration and polishing, specifically an electric polishing machine for interior and exterior decoration. Background Technology

[0002] Currently, in order to ensure the flatness and smoothness of the wall surface, sanding equipment is usually used to sand the wall surface in interior and exterior wall decoration and renovation projects. The decorators will carefully sand the wall surface. In the decoration and renovation field, especially interior decoration, an essential procedure is to whitewash the wall, and the commonly used whitewashing methods include painting and applying putty.

[0003] Sanding walls and ceilings requires different tools depending on the location. For walls, where angles are easy to work with, a wall grinder can be used. However, for ceilings, which are higher and have more difficult angles, manual sanding with sandpaper is necessary. This method is inefficient, labor-intensive, and the sanding effect depends heavily on the worker's skill level, making it difficult to control.

[0004] In summary, this utility model provides an electric polishing machine for indoor and outdoor decoration to solve the above problems. Utility Model Content

The end of each column away from the extension column is fixedly connected to the surface of the movable base, and the other end of each column is fixedly connected via an adjusting plate. One end of each extension column is movably inserted into the column. The support mechanism includes a fixed plate and a rotating plate. The ends of each extension column not inserted into the column are vertically connected to the fixed plate. The rotating plate is rotatably connected between the two fixed plates. The sander is mounted on the rotating plate. The adjusting plate and the rotating plate are connected via an adjusting screw. One end of the adjusting screw is rotatably connected to the rotating plate, and the other end of the adjusting screw passes through the adjusting plate and is fixedly connected to a handle.

[0007] Furthermore, each of the fixed plates has a directional rod vertically connected to its bottom. The end of the directional rod away from the fixed plate moves through the adjustment plate and is fixedly connected by a fine-tuning handle.

[0008] Furthermore, a directional hole is provided on the adjusting plate, and a slide block is provided in the directional hole. One end of the adjusting screw passes through the slide block and is connected to the slide block by a thread.

[0009] Furthermore, a keyway is provided in the limiting hole, the slide block is matched and contacted with the keyway, and limit rings are fixedly connected to both ends of the slide block, and the limit rings are respectively set at the upper and lower ends of the adjusting plate.

[0010] Furthermore, a locking groove is provided on the side of the flip plate near the flip plate, and a push plate is movably disposed in the locking groove. One end of the push plate is connected to the locking groove by a locking spring, and the other end of the push plate is fixedly connected to a locking rod. The end of the locking rod away from the push plate moves through the flip plate and is disposed on one side of the fixed plate.

[0011] Furthermore, a steering wheel is installed on the side of the fixed plate near the flip plate, and the steering wheel has multiple locking rod holes, with two of the locking rod holes forming an angle with the center of the steering wheel.

[0012] Furthermore, the bottom of the movable base is equipped with multiple casters, which are arranged symmetrically to each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, by setting an adjusting screw, can adjust the grinding height of the wall grinder by using the threaded locking connection between the adjusting rod and the slide block. The adjustable screw, which can be fixed, can determine a large range of grinding heights. The slide block, which can be adjusted by a small distance, allows the wall grinder to move up and down in a small range within the slide block's range. When grinding the ceiling, manual adjustment can be made according to the thickness to be ground on the ceiling, making it more flexible and efficient when grinding indoor ceilings.

[0015] 2. This utility model, by setting a steering wheel and a locking rod, can adjust the angle between the flip plate and the fixed plate, thereby adjusting the grinding angle of the wall grinder. It can grind both walls and ceilings. Depending on the grinding position, after adjustment, the surface can be ground more stably. Attached Figure Description
