Description

Technical Field

[0001] This utility model provides a building interior wall sanding device with a dust suction function, belonging to the technical field of wall sanding machine. Background Technology

[0002] In the construction and decoration industry, sanding interior walls is a common and important process. A smooth, flat wall surface not only enhances the overall aesthetics of the building but also paves the way for subsequent wall decoration work. Traditional interior wall sanding methods often involve manual hand-held sanding. This is not only inefficient and labor-intensive, but also often fails to guarantee consistent sanding results, leading to inconsistent wall smoothness and finish.

[0003] With the development of technology and the increasing demands for construction quality and efficiency in the construction industry, interior wall grinding devices have emerged. These devices typically consist of a grinding disc, a drive motor, a dust extraction system, and a housing. Sandpaper is placed on the grinding disc, and the drive motor provides rotational force to grind the wall surface. The housing is positioned at the grinding disc to reduce dust dispersion, while the dust extraction system promptly removes the dust generated during grinding, effectively reducing dust in the room, improving the working environment, protecting the health of construction workers, and preventing dust pollution of surrounding items and the environment. Although the dust extraction system can remove most of the dust, some dust still adheres to the inside of the housing. During prolonged grinding operations, a large amount of dust and debris accumulates inside the housing. If this dust and debris are not cleaned promptly, it will affect the dust extraction effect of the system and reduce the device's working efficiency.

[0004] However, existing grinding device housing designs often present difficulties in disassembly. Existing housings use bolt connections, requiring various tools and significant time and effort to disassemble. Furthermore, the housings are often integrally molded, leaving numerous nooks and crannies, making cleaning even after disassembly quite troublesome. Utility Model Content

By operating the screw 17, the rotation of the screw 17 can be converted into the movement of the slider 18, which in turn drives the sliding plate 15 to slide via the connecting rod 19.

[0028] The principle of this utility model

[0029] like Figure 1 , 2 As shown in Figure 3, when using this application, the worker holds the handheld part 1, makes the cover fit against the interior wall of the building, starts the grinding motor 7, and uses the rotation of the rotating disk 9 to drive the sandpaper 10 to rotate, thereby grinding the interior wall; the cover can reduce the spread of dust; at the same time, the external dust collection equipment is connected to the dust collection pipe 6, which can absorb and treat the dust generated during grinding, reducing the pollution inside the building.

[0030] When it is necessary to disassemble the cover for cleaning, such as Figure 4 , 5 As shown, by turning the screw 17, the sliding plate 15 and the insert rod 14 move away from the two limiting plates under the drive of the slider 18, so that the insert rod 14 disengages from the insertion hole 13. Without the use of tools, the fixation of the two covers can be quickly released. Not only can the two covers be removed quickly, but the separation of the two covers is also completed, which is convenient for cleaning after disassembly.
