Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically a polishing device for civil engineering and decoration construction. Background Technology

[0002] Grinding, a surface modification technology, generally refers to a processing method that uses a rough object to change the physical properties of a material surface through friction. Its main purpose is to obtain a specific surface roughness. A grinding device is a piece of equipment used to grind the surface of an object, widely used in metal processing, wood processing, stone processing, jewelry making, and car detailing, among other fields. This device uses different methods and techniques to achieve the purpose of smoothing, polishing, or removing imperfections from the surface of an object. In architectural decoration construction, grinding devices are specifically designed for grinding the surfaces of building materials such as walls, floors, and ceilings. These devices aim to improve construction efficiency, improve the construction environment, and ensure the quality of decoration. Currently, there is a handheld architectural wall grinding device that can remove uneven parts, old coatings, stains, etc., from the wall surface, making it smoother and easier for subsequent painting, wallpapering, or other decorative treatments. However, when grinding walls at higher elevations, the grinding device needs to be lifted by the arm, which can easily cause arm pain for construction workers over a long period. Therefore, we propose a grinding device for civil engineering and decoration construction. Utility Model Content

[0005] The grinding rod is hollow, with the upper curved part connected to the hose and the lower curved part connected to the vacuum pipe. A branch rod is also provided at the lower end of the grinding rod.

[0006] The outer casing is fixedly connected to the motor, and a circular groove is cut into the outer casing.

[0007] The mobile device includes a connecting seat, a branch rod inserted into the connecting seat, the connecting seat slidably installed in the support seat, a guide frame fixedly installed on the upper part of the support seat, a groove opened below the guide frame, the connecting seat can slide freely in the groove, an inclined block fixedly connected to the lower part of the connecting seat, a wedge block provided below the inclined block, the wedge block slidably installed in the groove, a screw rod rotatably installed on the support seat, the wedge block and the screw rod being threadedly connected, a wheel fixedly connected to the end of the screw rod, a base fixedly installed at the bottom of the support seat, four wheels rotatably installed on the lower part of the base, and a handrail fixedly installed on the rear side of the support seat.

[0008] The connector is composed of a cylinder and a block, and has slots.

[0009] The vacuum cleaner is fixedly installed on the left side of the support base, and a dust bag is also provided next to the vacuum cleaner. The dust bag is fixedly connected to the support base.

[0010] The inclined block has a groove, and the lower part of the inclined block fits into the upper part of the wedge.

[0011] This utility model has at least the following beneficial effects:

[0012] This utility model is simple and easy to use, saving effort. When sanding a wall, hold the sanding rod, press the sanding disc against the wall, start the motor and vacuum cleaner, and sand the wall. The dust from sanding will be sucked into the dust bag by the vacuum cleaner, preventing air and environmental pollution. When sanding a higher wall or ceiling, insert the sanding rod into the connecting seat, rotate the wheel to push the connecting seat upward until the sanding disc is in close contact with the wall or ceiling, then start the motor and vacuum cleaner. At this time, you can also hold the handle to push the support base to move, making it convenient to sand different parts. Attached Figure Description
