Description

Technical Field

[0001] This utility model relates to a sanding machine, and more particularly to a wall sanding machine with a spotlight structure. Background Technology

[0002] A wall sander is an electric tool used for sanding building surfaces such as walls and ceilings. It is mainly used to remove unevenness, sanding marks, particles, and joints from putty layers, making the wall surface smoother and more delicate, providing a good foundation for subsequent painting or wallpapering. In order to improve the practicality of the wall sander, a lighting device is installed on it to provide precise local lighting, solving the problems of light obstruction and dust interference during the sanding process, thereby improving the accuracy, efficiency and safety of construction.

[0003] In existing technologies, such as the AC brushless wall sander disclosed in CN219747313U, the power supply device for connecting to AC mains power and converting AC mains power to DC power is designed as an AC-to-DC power adapter structure that is separate from and detachably electrically connected to the controller. This facilitates the maintenance of the power supply and controller parts during use. If either part is damaged, only the damaged part needs to be repaired or replaced, which not only improves the convenience of maintenance but also reduces maintenance costs. Furthermore, a DC power input interface for detachable connection of the AC-to-DC power adapter is specially designed on the controller. Therefore, during use, the user can also remove the AC-to-DC power adapter according to the usage needs and replace it with other power supply devices that are compatible with the DC power input interface, thereby broadening the power supply usage of the machine. At the same time, spotlights for lighting are provided on the protective cover for the convenience of using the wall sander.

[0004] However, it also has some shortcomings. For example, when sanding the wall, the sanding depth of the sanding block 223 cannot be adjusted according to the thickness of the layer to be sanded. In this case, the wall is easily damaged due to over-sanding when the sander is sanding the wall. Utility Model Content

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0018] This embodiment mainly describes the structure of a wall sander with a spotlight structure, as follows: like Figures 1-10As shown, a wall sander with a spotlight structure includes a wall sander body consisting of a handle part 1 and a sanding part. The sanding part consists of a protective cover 2, a sanding assembly 22 and a drive device 3 (such as a drive motor). The sanding assembly 22 is installed in the protective cover 2, and the drive device 3 is installed on the top of the protective cover 2. The drive device 3 is used to control the rotation of the sanding assembly 22. The protective cover 2 is connected to the handle part 1. A spotlight device 4 for lighting is also provided on the top of the protective cover 2. The protective cover 2 includes a cover body 21 connected to the end of the handle part 1 and a first mounting groove 211 formed in a ring at the bottom of the cover body 21. Multiple connecting posts 24 are evenly arranged in the first mounting groove 211, with the top of the connecting posts 24 connected to the cover body 21 and a first screw hole 241 opened at the bottom of each connecting post 24. At the same time, an abutment ring 23 is slidably arranged in the first mounting groove 211, and the abutment ring 23 has the same number of first through holes 231 as the number of connecting posts 24. The abutment ring 23 is slidably connected to the connecting posts 24 through the first through holes 231. A spring 25 is sleeved on each connecting post 24, with one end of the spring 25 connected to the cover body 21 and the other end connected to the abutment ring 23. Finally, a first bolt 26 is provided in each of the first through holes 231 and screwed into the first screw hole 241. The elastic force of the spring 25 is greater than the pressure when the abutment ring 23 contacts the wall. When using a wall sander, first adjust the length of the abutment ring 23 extending out of the first mounting groove 211 according to the thickness of the layer to be sanded on the wall. This allows the height of the sanding end of the sanding component 22 protruding from the bottom of the cover 21 to be adjusted by changing the length of the abutment ring 23 extending out of the first mounting groove 211. Then connect the wall sander to a power source, and the user controls the cover 2 and the sanding component 22 to move towards the wall surface to be sanded using the handle 1. Simultaneously, the drive device 3 is activated to rotate the sanding component 22 within the cover 21. When the sanding end of the sanding component 22 contacts the wall surface, it can sand the layer to be sanded. After the sanding end of component 22 contacts the layer to be sanded, it will form a depression on the entire wall surface. The sanding end of the sanding component 22 is located in the depression, while the abutment ring 23 on the cover 21 abuts against the unsanded layer to be sanded. This can restrict the movement of the sanding end of the sanding component 22 toward the wall, thus ensuring that the sanding end of the sanding component 22 will not continue to sand the wall. The sanding depth of the sanding block 223 on the wall can be adjusted by adjusting the length of the abutment ring 23 extending out of the first mounting groove 211, thereby ensuring that the wall will not be damaged due to over-sanding when the wall sander is sanding the wall. When adjusting the length of the abutment ring 23 extending out of the first mounting groove 211, it can be done by unscrewing the first bolt 26 out or into the first screw hole 241. When the first bolt 26 is unscrewed out of the first screw hole 241, the abutment ring 23 can move downward along the connecting post 24 in the first mounting groove 211 through the first through hole 231, thus increasing the length of the abutment ring 23 extending out of the first mounting groove 211. When the first bolt 26 is screwed into the first screw hole 241, the abutment ring 23 can be pressed into the first mounting groove 211 by the bolt head of the first bolt 26, thus shortening the length of the abutment ring 23 extending out of the first mounting groove 211. The spring 25 facilitates the extension of the abutment ring 23 from the first mounting groove 211, and at the same time, the spring 25 can also prevent the abutment ring 23 from being pressed into the first groove when it abuts against the wall, thereby ensuring the reliability of the abutment ring 23.

[0019] Furthermore, the first through hole 231 is countersunk 27 at the end away from the first mounting groove 211, and the bolt head of the first bolt 26 is located in the countersunk 27. This avoids the problem of uneven bottom of the abutment ring 23 due to the protruding bolt head. A first bearing 28 is provided in each countersunk hole 27, and the outer ring of the first bearing 28 is fixedly connected to the hole wall of the countersunk hole 27, while the inner ring of the first bearing 28 is fixedly connected to the head of the first bolt 26. In this way, the first bolt 26 can be confined in the first through hole 231, thereby avoiding the problem of the first bolt 26 being lost. In order to facilitate the tightening of the first bolt 26, the first bolt 26 is an internal hex bolt.

[0020] To facilitate maintenance of the grinding assembly 22, the grinding assembly 22 includes a connecting plate 221 installed in the cover 21 and a connecting shaft 222 installed on the top of the connecting plate 221. The top of the connecting shaft 222 extends out of the cover 21 and connects to the output end of the drive device 3, so that the drive device 3 can control the rotation of the connecting plate 221. To facilitate the rotation of the connecting plate 221, the connecting shaft 222 is rotatably connected to the cover 21. A second screw hole 2211 and a grinding block 223 are provided at the bottom of the connecting plate 221. A second through hole 2232 aligned with the second screw hole 2211 is provided on the grinding block 223, and a second bolt 224 screwed into the second screw hole 2211 is provided in the second through hole 2232. In this way, when the grinding block 223 needs to be replaced, the second bolt 224 can be removed from the second screw hole 2211. When installing a new grinding block, the second bolt 224 can be removed. At step 223, the grinding block 223 to be installed is placed in the cover 21, and the second through hole 2232 is aligned with the second screw hole 2211. Then, the second bolt 224 is screwed into the second screw hole 2211, thus completing the installation of the grinding block 223. In order to ensure the stability of the grinding block 223 when rotating, the second screw hole 2211 is located at the center of the bottom of the connecting plate 221. In order to ensure the firmness of the connection between the grinding block 223 and the connecting plate 221, a pressure block 225 is provided at the bottom of the grinding block 223 for pressing the grinding block 223. The pressure block 225 is located between the bolt head of the second bolt 224 and the grinding block 223. In order to avoid the second bolt 224 and the pressure block 225 affecting the grinding effect of the grinding block 223 on the wall, a second mounting groove 2231 for accommodating the pressure block 225 is provided at the bottom of the grinding block 223.

[0021] Furthermore, in order to further improve the stability of the rotation of the grinding block 223, multiple connecting rods 228 are evenly arranged at the bottom of the connecting plate 221, and multiple connecting holes 227 matching the connecting rods 228 are opened at the top of the grinding block 223, and the connecting rods 228 are inserted into the connecting holes 227.

[0022] Furthermore, in order to improve the smoothness of the rotation of the connecting disc 221, a second bearing 226 is provided on the connecting shaft 222. At the same time, in order to ensure the reliability of the connection between the connecting disc 221 and the cover 21, a third mounting groove 2261 for accommodating the second bearing 226 is provided on the top of the cover 21.

[0023] The pressure block 225 includes a mounting block 2251 installed in the second mounting groove 2231, and a third through hole 2253 is provided at the center of the mounting block 2251 for the threaded part of the second bolt 224 to pass through. A fourth mounting groove 2252 in a circular shape is provided around the third through hole 2253 on the top of the mounting block 2251, and the top of the fourth mounting groove 2252 is open. Then, multiple spring telescopic rods 2 are evenly arranged in the fourth mounting groove 2252. 254. At the same time, a pressure ring 2255 is slidably disposed in the fourth mounting groove 2252, and the bottom of the pressure ring 2255 is connected to the telescopic end of the spring telescopic rod 2254. Thus, when the pressure block 225 is installed in the second mounting groove 2231, the top of the pressure ring 2255 abuts against the grinding block 223. As the second bolt 224 is tightened, the pressure ring 2255 can press the grinding block 223 tightly, thereby ensuring the firmness of the connection between the grinding block 223 and the connecting plate 221.
