Description

Technical Field

[0001] This utility model relates to the field of polishing mechanism technology, and in particular to a wall polishing mechanism for interior decoration. Background Technology

[0002] During the interior decoration process, it is usually necessary to level the interior walls and sand any protrusions on the wall to make subsequent decoration easier. However, walls include ceilings. If the ceiling is to be sanded, the person needs to stand below the wall and then use a sander to sand it.

[0003] However, existing sanders do not have a protective structure. Therefore, during the sanding process, protruding materials on the wall will be crushed and fall below, causing discomfort to the personnel. To address this issue, we propose a wall sanding mechanism for interior decoration and renovation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a wall polishing mechanism for interior decoration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wall sanding mechanism for interior decoration includes a hand handle, a sanding wheel at the end of the hand handle, a sliding ring sleeved on the outside of the hand handle, a protective cover on the outside of the sliding ring, the protective cover being cylindrical and located outside the sanding wheel, a sliding block on the inner wall of the sliding ring, and sliding grooves formed around the outer wall of the hand handle, with the sliding block extending into the interior of the sliding groove.

[0007] The protective cover can protect the grinding wheel, and the dust generated during the grinding process will fall into the inside of the protective cover, thus preventing it from falling directly onto the workers and resulting in a better grinding effect.

[0008] Preferably, a support shaft is provided inside the sliding slot, and the sliding block is sleeved on the outside of the support shaft;

[0009] The protective cover can be slidable, which improves the polishing effect of the grinding wheel. At the same time, the sliding stability of the protective cover is better, preventing the protective cover from detaching.

[0010] Preferably, a support spring is sleeved on the outside of the support shaft, one end of the support spring is fixedly connected to the sliding block, and the other end of the support spring is fixedly connected to the inner wall of the sliding slot.

[0011] The protective cover can be pulled and its sliding range adjusted, which can support the grinding wheel and prevent it from denting due to excessive grinding force.

[0012] Preferably, the end of the support shaft is provided with a movable slot, the inside of the end of the support shaft is provided with a threaded sleeve, and the outer wall of the threaded sleeve is provided with support top blocks all around, the support top blocks extending through the movable slot to the outside of the support shaft;

[0013] The position of the support block can be adjusted by adjusting the threaded sleeve, thereby limiting the movement distance of the sliding block.

[0014] Preferably, a rotating threaded rod is inserted into the end of the support shaft, and a threaded sleeve is sleeved on the outside of the rotating threaded rod, and the threaded sleeve is threadedly connected to the rotating threaded rod;

[0015] By rotating the threaded rod, the threaded sleeve can be moved, making it easier to move the threaded sleeve and the support block. At the same time, the threaded self-locking mechanism of the rotating threaded rod can position the threaded sleeve.

[0016] Preferably, the end of the rotating threaded rod is provided with a first transmission gear, and the outer wall of the first transmission gear is provided with a second transmission gear, and the inner wall of the second transmission gear meshes with the outer walls of multiple sets of first transmission gears.

[0017] This causes the rotating threaded rod to drive the first transmission gear to rotate during rotation, which in turn drives the second transmission gear to rotate, thus allowing multiple sets of rotating threaded rods to rotate synchronously, making the position adjustment of the threaded sleeve more convenient.

[0018] Preferably, a rotating sleeve is fitted onto the outside of the hand grip, and the inner wall of the rotating sleeve is fixedly connected to the outer wall of the second transmission gear.

[0019] It allows personnel to directly rotate the rotating sleeve from the outside, thereby driving the second transmission gear to rotate, making the rotation of the second transmission gear more convenient.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model allows the protective cover to be placed against the wall, and then the hand handle can be pushed to move the grinding wheel to complete the grinding of the wall. At the same time, the dust generated after grinding will fall directly into the inside of the protective cover, which can protect the dust and prevent the dust from falling directly onto the personnel, thus making the grinding effect better.

[0022] 2. This utility model can drive the second transmission gear to rotate by rotating the rotating sleeve, which in turn drives multiple sets of first transmission gears to rotate, causing the first transmission gears to drive the rotating threaded rod to rotate. This allows the threaded sleeve to adjust the position of the support top block, which can limit the movement distance of the sliding block, thereby preventing the grinding wheel from applying too much force and causing the wall to dent.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 The wall sanding mechanism for interior decoration shown has a sanding wheel 2 at the end of a handheld handle 1. A sliding ring 4 is then fitted onto the outside of the handheld handle 1, and a protective cover 3 is provided on the outside of the sliding ring 4. The protective cover 3 is cylindrical and located outside the sanding wheel 2. A sliding block 5 is provided on the inner wall of the sliding ring 4, and sliding slots 6 are formed on all four sides of the outer wall of the handheld handle 1, so that the sliding block 5 extends into the interior of the sliding slots 6. A support shaft 7 is provided inside the sliding slots 6, and the sliding block 5 is fitted onto the outside of the support shaft 7, so that a support spring 8 is fitted onto the outside of the support shaft 7. One end of the support spring 8 is fixedly connected to the sliding block 5, and the other end of the support spring 8 is fixedly connected to the inner wall of the sliding slot 6.

[0030] For a detailed description of the rotating threaded rod 10 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4 A movable slot 9 is provided at the end of the support shaft 7. A threaded sleeve 11 is then provided inside the end of the support shaft 7. Support top blocks 12 are provided around the outer wall of the threaded sleeve 11. The support top blocks 12 extend through the movable slot 9 to the outside of the support shaft 7, so that a rotating threaded rod 10 is inserted into the end of the support shaft 7. The threaded sleeve 11 is sleeved on the outside of the rotating threaded rod 10, so that the threaded sleeve 11 and the rotating threaded rod 10 are threadedly connected. A first transmission gear 13 is provided at the end of the rotating threaded rod 10. A second transmission gear 15 is provided around the outer wall of the first transmission gear 13. The inner wall of the second transmission gear 15 meshes with the outer walls of multiple sets of first transmission gears 13, so that a rotating sleeve 14 is sleeved on the outside of the hand grip 1, and the inner wall of the rotating sleeve 14 is fixedly connected to the outer wall of the second transmission gear 15.

[0031] Working principle: When using this utility model, the protective cover 3 is placed against the wall, and then the hand handle 1 is used to move the grinding wheel 2, so that the protective cover 3 slides on the grinding wheel 2, thereby allowing the grinding wheel 2 to grind the protruding parts on the wall. At the same time, the dust generated during grinding is blocked by the protective cover 3, preventing it from falling directly onto the workers, making the grinding wheel 2 more convenient.

[0032] Simultaneously, rotating the rotating sleeve 14 causes the second transmission gear 15 to rotate, which in turn causes the second transmission gear 15 to synchronously drive multiple sets of first transmission gears 13 to rotate. The first transmission gears 13 then drive the rotating threaded rod 10 to rotate, causing the threaded sleeve 11 and the support top block 12 to move. This allows the support top block 12 to block the movement of the sliding block 5, thereby limiting the sliding range of the protective cover 3. This prevents the grinding wheel 2 from applying excessive grinding force, which could cause dents in the wall, and improves the performance of the grinding wheel 2.
