[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 The present invention provides the following technical solution:
[0027] A wall sander support structure includes a trolley 1. A latching block 2 is fixedly connected to the front side of the top of the trolley 1, and a sanding component 3 is movably connected to the top of the latching block 2. A dust collection component 4 is fixedly connected to the rear side of the top of the trolley 1, and the dust collection component 4 is located behind the sanding component 3. The dust collection component 4 includes a storage box 401. A suction hose 402 is fixedly connected to the top of the storage box 401, and a fan 403 is fixedly connected to the bottom of the rear side of the storage box 401. A collection cover 404 is fixedly connected to the side of the suction hose 402 away from the storage box 401, and the collection cover 404 is fixedly connected to the top of the sanding component 3. Movable blocks 405 are movably connected to the front and rear sides of the inner wall of the storage box 401, and a filter box 406 is fixedly connected between the opposite sides of the two movable blocks 405.
[0028] In this embodiment: the lifting motor 302 drives the threaded rod 304 to rotate, which in turn drives the slider 305 to move smoothly, simultaneously pushing the moving cylinder 306 and the grinding machine body 307 to rise and fall. This can adapt to the grinding needs of different wall heights. At the same time, the locking structure formed by the buckle block 2 and the rotating ring 308 enables quick loading and unloading of the grinding component 3 and the trolley 1. When needed, it can be switched to handheld operation, which takes into account both the stability of fixed operation and the convenience of flexible operation, improving the ease of use of the grinding component 3. Then, under the action of the fan 403, the storage can be extracted. The air inside the chamber 401 forms a negative pressure, causing the dust generated during the grinding process to pass sequentially through the collection cover 404 and the suction hose 402 into the storage chamber 401, and finally flow into the filter box 406 for centralized treatment. This prevents dust from spreading and polluting the environment at the source, ensuring the health of the operators. At the same time, with the help of the guiding structure formed by the moving block 405, the filter box 406 moves smoothly under the constraint of the moving block 405, realizing the quick disassembly and assembly of the filter box 406, facilitating dust cleaning, ensuring the normal use of the suction assembly 4, and improving the ease of use of the suction assembly 4.
[0029] Specifically, such as Figure 4As shown, the grinding assembly 3 includes a fixed cylinder 301. A lifting motor 302 is fixedly connected to the bottom of the inner wall of the fixed cylinder 301, and a connecting ring 303 is fixedly connected to the bottom of the surface of the fixed cylinder 301. A threaded rod 304 is fixedly connected to the top of the lifting motor 302, and a slider 305 is threadedly connected to the surface of the threaded rod 304. A movable cylinder 306 is fixedly connected to the surface of the slider 305, and a grinding machine body 307 is rotatably connected to the top of the movable cylinder 306. A rotating ring 308 is rotatably connected to the surface of the connecting ring 303, and the rotating ring 308 engages with the snap-fit block 2.
[0030] Specifically, such as Figure 4 As shown, the slider 305 has a threaded hole 5 inside that is used to cooperate with the threaded rod 304, and there are slide rods 6 on both sides inside the slider 305. The slider 305 is slidably connected to the surface of the slide rods 6, and the slide rods 6 are located inside the fixed cylinder 301.
[0031] Specifically, such as Figure 4 As shown, the bottom of the rotating ring 308 is provided with a slot 7 for use with the buckle block 2, and the surface of the buckle block 2 is in contact with the inner wall of the slot 7.
[0032] In this embodiment: the use of the snap-fit block 2 and the slot 7 together forms a snap-fit structure. The rotating ring 308 rotates smoothly under the constraint of the connecting ring 303, and simultaneously drives the slot 7 to rotate along the snap-fit block 2 to complete the engagement, realizing the quick loading and unloading of the grinding component 3 and the trolley 1. When needed, it can be switched to hand operation, taking into account both the stability of fixed operation and the convenience of flexible operation. At the same time, the use of the threaded rod 304 and the threaded hole 5 together allows the slider 305 to rise and fall smoothly along the threaded rod 304 under the drive of the lifting motor 302. The double guide structure formed by the slide rod 6 ensures the smooth movement of the moving cylinder 306 and the grinding machine body 307, which can adapt to the grinding needs of different wall heights and improve the convenience of using the grinding component 3.
[0033] Specifically, such as Figure 5 As shown, the inside of the collection cover 404 is provided with a mounting hole 8 for use with the main body 307 of the grinder, and the surface of the main body 307 of the grinder is in contact with the inner wall of the mounting hole 8.
[0034] Specifically, such as Figure 5 As shown, the front and rear sides of the inner wall of the storage box 401 are provided with moving grooves 9 for use with the moving block 405, and the surface of the moving block 405 is in contact with the inner wall of the moving groove 9.
[0035] In this embodiment: the use of the grinding machine body 307 and the mounting hole 8 together forms a stable mounting structure, so that the collection cover 404 can be stably fixed on the surface of the grinding machine body 307, which facilitates the collection of dust. At the same time, the use of the moving block 405 and the moving groove 9 together allows the moving block 405 to move smoothly under the restriction of the moving groove 9, and synchronously drives the filter box 406 to move, realizing the quick disassembly and assembly of the filter box 406, which facilitates the cleaning of dust, ensures the normal use of the dust collection component 4, and improves the ease of use of the dust collection component 4.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a controller 10 is fixedly connected to the front side of the fixed cylinder 301 and the rear side of the top of the storage box 401, and the controller 10 is electrically connected to the polishing assembly 3 and the dust collection assembly 4.
[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, extension plates 11 are fixedly connected to both sides of the trolley 1, and adjustable feet 12 are fixedly connected to the bottom of the extension plates 11.
[0038] In this embodiment: the height of the device can be adjusted according to the actual situation through the two adjustable feet 12, which can provide auxiliary support for the trolley 1 and avoid deviation during the sanding process, thus ensuring the sanding effect of the wall. At the same time, the operating parameters of the sanding component 3 and the dust collection component 4 can be set by the controller 10. The moving cylinder 306 and the sander can be smoothly raised and lowered by the lifting motor 302 to adapt to the sanding needs of different wall heights. The fan 403 can also generate negative pressure so that the dust generated during the sanding process enters the storage box 401 through the collection cover 404 and the dust collection hose 402, and finally flows into the filter box 406 for centralized treatment, which improves the practicality of the device.
[0039] Working Principle: When sanding a wall, first align the locking block 2 with the slot 7. Then, manually rotate the rotating ring 308 to drive the slot 7 to rotate along the locking block 2, completing the engagement and installing the sanding component 3. With the help of the trolley 1, the device can be moved smoothly to adjust the sanding position. Subsequently, the operator sets the operating parameters of the sanding component 3 and the dust extraction component 4 via the controller 10, starts the lifting motor 302 to drive the threaded rod 304 to rotate, causing the slider 305 to move smoothly along the sliding rod 6. Simultaneously, this drives the moving cylinder 306 and the sander body 307 to rise and fall smoothly, adapting to sanding needs at different wall heights and ensuring stable sanding operations. When handheld operation is required, manually rotate the rotating ring 308. 8. Release the fixed state of the sanding component 3 to manually adjust the angle of the sander. In conjunction with the controller 10 at the fixed cylinder 301, complete the fine sanding operation. During the sanding process, the controller 10 simultaneously starts the fan 403, which can draw out the air in the storage box 401 to form a negative pressure. This allows the dust generated during the sanding process to enter the storage box 401 through the collection cover 404 and the dust suction hose 402, and finally flow into the filter box 406 for centralized treatment. This prevents dust from splashing and polluting the environment from the source, ensuring both the sanding effect of the wall and the health of the operators. After the sanding is completed, the filter box 406 can be pulled out to clean the collected dust. After cleaning, the filter box 406 can be reset to restore the dust collection function and prepare for subsequent sanding.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
