Description

Technical Field

[0001] This utility model relates to the field of decoration engineering, specifically to a wall grinding device for decoration engineering. Background Technology

[0002] During construction, some building materials require grinding after installation or construction to ensure a smooth, even surface that meets the desired aesthetic and functional requirements. Common building materials requiring grinding include concrete, plaster, and marble. Grinding not only improves the material's appearance but also provides a better foundation for subsequent painting, laying, and use.

[0003] The dust generated during sanding primarily originates from the materials being sanded, such as architectural decorative wall materials. If inhaled, this dust can cause several health hazards. Furthermore, the dust generated during sanding not only harms the operators but also pollutes the surrounding environment. The dispersed dust floats in the air for a period before settling into the surrounding environment, affecting indoor air quality. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] First embodiment:

[0027] See Figures 1-3As shown, this utility model provides a wall sanding device for decoration and renovation projects, including a handheld tube 1 with an anti-slip rubber sleeve on its outer wall. A working box 3 is rotatably connected to the working end of the handheld tube 1. The handheld tube 1 and the working box 3 are connected through a connecting tube. An opening is provided on the side of the working box 3 away from the handheld tube 1, and a rotating disk 6 is rotatably connected to the opening. A driving component 4 is provided on the working box 3 to drive the rotating disk 6 to rotate. A sanding disc 5 is detachably connected to the movable end of the rotating disk 6. When using the device, the handheld tube 1 is used for hand operation. Since the working box 3 and the handheld tube 1 are rotatably connected, the working box 3 can be moved up and down. The driving component 4 drives the rotating disk 6 to rotate, and the rotating disk 6 drives the sanding disc 5 to rotate. The rotating sanding disc 5 can be used to sand the wall surface. Since the sanding disc 5 is detachably connected to the rotating disk 6, the sanding disc 5 can be easily disassembled and replaced, making it more convenient to use.

[0028] A fan 2 is provided on the side of the handheld tube 1 away from its working end. A cloth bag 201 is provided at the air outlet end of the fan 2. The fan 2 allows the gas to enter from the opening end of the working box 3, enter the handheld tube 1 through the connecting pipe, and be guided by the fan 2 to the cloth bag 201 for filtration before being discharged. This avoids pollution of the wall sanding working environment and achieves the protection of the construction environment.

[0029] The second embodiment differs from the first embodiment in that:

[0030] There are multiple rotating discs 6, arranged in an array within the opening of the work box 3. This allows for the use of multiple grinding discs 6 with grinding pads 5 to grind the wall surface, resulting in a better grinding effect. Specifically, in the connection structure of the rotating discs 6, the work box 3 has a partition 301 inside, and the rotating discs 6 are rotatably connected to the partition 301 via a rotating shaft. The drive assembly 4 includes a motor 401 and a first gear 402. The inner end of the rotating shaft is connected to the first gear 402, and it also includes a second gear 403 rotatably connected to the top surface inside the work box 3. The second gear 403 is located between two adjacent first gears 402 and meshes with the first gears 402 on both sides. The output end of the motor 401 is connected to any first gear 402 or second gear 403. The inner end of the connecting pipe is correspondingly set with the rotating disk 6. After the motor 401 is powered on, it can drive the first gear 402 or second gear 403 connected to it to rotate. The transmission of the first gear 402 or second gear 403 is realized by the gear meshing, thereby realizing the synchronous rotation of multiple rotating disks 6 in the same direction and realizing the sanding operation of the wall surface.

[0031] In the structure of the rotating disk 6, the rotating disk 6 includes a connecting disk 603 connected to the rotating shaft. The outer side of the connecting disk 603 is provided with an annular support airbag 601. The annular support airbag 601 can achieve flexible support for the connecting disk 603. The outer end of the support airbag 601 is connected to the connecting disk 603 for fixing the grinding disc 5. The grinding disc 5 is fixed by the connecting disk 603. Since there is a certain pressure inside the support airbag 601, the surface of the support airbag 601 is relatively hard and elastic, thus having a good support effect. When supporting the grinding disc 5, it can help to disperse the pressure and avoid excessive local pressure, thereby achieving flexible support for the grinding disc 5. It avoids strong contact between the grinding disc 5 and the wall surface, and can correct the grinding direction of the grinding disc 5 in time, making the operation more flexible. Moreover, the flexible structure can more precisely adapt to the subtle changes in the wall surface, making the grinding effect more accurate and suitable for meticulous grinding work.

[0032] Furthermore, the connecting disc 603 is disc-shaped, with a recessed hole 602 at its axis and a limiting protrusion on the inner side of the recessed hole 602. A connecting block 501, which inserts into the recessed hole 602, is located at the axis of the grinding disc 5. The outer wall of the connecting block 501 has a groove, and the connecting block 501 is made of rubber. When installing the grinding disc 5, the insertion of the connecting block 501 into the recessed hole 602 and the matching of the groove with the limiting protrusion are used to install the grinding disc 5. The grinding disc 5 is annular. The polishing disc 5 is preferably annular or circular, so that when installing or removing the polishing disc 5, the user's fingers can be inserted into the inside of the connecting block 501, thereby assisting in the removal and removal of the polishing disc 5. In addition, the polishing disc 5 and the connecting plate 603 have matching grooves and strips on their facing surfaces. The grooves and strips can be used to fix the polishing disc 5, preventing it from stopping when pressing against the wall and ensuring the rotation and polishing effect of the polishing disc 5.

[0033] The third embodiment differs from the first embodiment in that:

[0034] The cloth bag 201 is sleeve-shaped, with one end connected to the fan 2 and the other end tightened by a strap. This design allows the material inside the cloth bag 201 to be discharged after the strap is loosened, thus achieving the cleaning process of the cloth bag 201.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
