DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7 As shown, a wall grinding device for building decoration includes a base 1 and a lifting structure 2, the base 1 is movable, the lifting structure 2 is vertically fixedly connected to the upper surface of the base 1, the lifting structure 2 is used to drive the grinding block 6 to move up and down for grinding, and a fixed rod 3 is fixedly arranged on the top of the lifting structure 2. The grinding device also includes a rotating component and a reciprocating component;

[0029] There are two sets of rotating components, which are symmetrically fixed at both ends of the fixed rod 3. The fixed rod 3 is connected to the support plate 5 through the rotating components.

[0030] The reciprocating motion component is arranged at the front side of the support plate 5, and the support plate 5 is connected with the grinding block 6 by sliding cooperation through the reciprocating motion component. The grinding block 6 is a square block. The reciprocating motion component is used to drive the square grinding block 6 to grind the wall back and forth.

[0031] In some specific embodiments, such as Figure 4 or Figure 5 As shown, in order to facilitate driving the sanding block 6 to sand the wall back and forth, the reciprocating motion assembly includes a driving wheel 10, a fan-shaped block 11 and a moving plate 8. A plurality of guide sleeves 7 are fixedly arranged on the side of the support plate 5. Both ends of the moving plate 8 are fixedly connected with slide bars 9 that slide with the corresponding guide sleeves 7. The slide bars 9 are slidably connected to the inner side of the corresponding guide sleeves 7. The moving plate 8 is slidably connected to the support plate 5 through the slide bars 9. A motor 12 is fixed on the side of the support plate 5 away from the guide sleeve 7. The output end of the motor 12 passes through the support plate 5. ， It is connected to one side of the plane of the sector block 11. Two driving wheels 10 are rotatably provided on one side of the movable plate 8 close to the support plate 5, and the sector block 11 is cooperated and located between the two driving wheels 10. When the sector block 11 rotates, it squeezes the driving wheel 10 on one side through the arc surface, causing the driving wheel 10 to drive the movable plate 8 to move laterally in one direction. When the sector block 11 rotates to the position of the driving wheel 10 on the other side, the driving wheel 10 on the other side drives the movable plate 8 to move laterally in the leading direction, thus realizing reciprocating motion. The side of the slide bar 9 away from the support plate 5 is connected to the grinding block 6.

[0032] During actual work, the base 1 is fixed horizontally on the ground, the lifting structure 2 drives the grinding block 6 to grind different heights, and the motor 12 is started. The motor 12 drives the irregular disc-shaped fan-shaped block 11 to rotate. The rotation of the fan-shaped block 11 can drive the driving wheels 10 on both sides to move left and right while rolling. Since the driving wheel 10 is rotatably connected to the movable plate 8, the movable plate 8 can drive the sliding rods 9 at both ends to slide back and forth along the guide sleeve 7, so that the movable plate 8 can drive the grinding block 6 to reciprocate left and right to grind the wall. Since the grinding block 6 is a square block and the movement state is reciprocating left and right, the wall can be fully polished to avoid grinding dead corners.

[0033] In some specific embodiments, such as Figure 2 or Figure 3 As shown, in order to facilitate the grinding of the top by the grinding block 6, each set of rotating components includes a side plate 4, an arc-shaped sliding hole 16 and a slider 15. The two ends of the support plate 5 are fixedly connected with a rotating shaft 13, the side plate 4 is rotatably connected with the rotating shaft 13, the arc-shaped sliding hole 16 is a quarter arc, and the arc-shaped sliding hole 16 is opened on the side of the side plate 4. Slide blocks 15 are fixed at both ends of the support plate 5, and the slider 15 is slidably connected to the inner side of the arc-shaped sliding hole 16. When the support plate 5 is in a vertical state, a vertical rotating rod 14 is fixedly connected between the rotating shaft 13 and the slider 15. A driving structure is provided on one of the side plates 4, and a positioning structure is provided on the other side plate 4.

[0034] In some specific embodiments, such as Figure 3 As shown, in order to facilitate driving the support plate 5 to drive the grinding block 6 to rotate, the driving structure includes a motor 21, the motor 21 is fixedly connected to the side of the side plate 4, the output end of the motor 21 is connected to the rotating shaft 13, and the rotation of the motor 21 can drive the rotating rod 14 and the slider 15 to rotate synchronously.

[0035] In some specific embodiments, such as Figure 2 As shown, in order to prevent the grinding block 6 from shaking during grinding, the positioning structure includes a plug plate 17, a plug plate 2 18 and a telescopic rod 20. The plug plate 17 and the plug plate 2 18 are both plugged into the same side plate 4. The plug plate 17 fits with the rear side of the support plate 5 in the vertical state, and the plug plate 2 18 fits with the upper surface of the support plate 5 in the horizontal state. The plug plate 17 and the plug plate 2 18 are used to fix the angle of the support plate 5, so that the grinding block 6 can maintain a horizontal state or a vertical state, and can grind the wall or the top of the building. A driving rod 19 is fixedly connected between the plug plate 17 and the plug plate 2 18, and a telescopic rod 20 is connected between the driving rod 19 and the side plate 4. A spring is sleeved on the outside of the telescopic rod 20, and the two ends of the spring are respectively connected to the driving rod 19 and the side plate 4.

[0036] After the vertical wall is polished, the driving rod 19 is pulled by hand to make the plug plate 17 and the plug plate 2 18 slide away from the support plate 5, and the limit of the plug plate 17 on the rear side of the support plate 5 is released, and the plug plate 17 and the plug plate 2 18 are pulled until they do not block the rotating support plate 5. At this time, the telescopic rod 20 is extended, the spring is in a stretched state, and the motor 21 is started. The motor 21 drives the slider 15 connected to the rotating rod 14 to make a circular motion. The slider 15 can slide along the arc-shaped sliding hole 16. Since the slider 15 is fixedly connected to the support plate 5, the support plate 5 also rotates. Movement, so that the slider 15 rotates to the other end of the arc-shaped sliding hole 16, and the motor 2 21 is stopped. At this time, the support plate 5 has rotated ninety degrees, and the driving rod 19 is released. Due to the resilience of the spring, the plug plate 1 17 and the plug plate 2 18 are reset. The plug plate 2 18 is now in contact with the upper surface of the support plate 5, and the support plate 5 is limited. By setting the plug plate 1 17 and the plug plate 2 18 to limit the angle of the grinding block 6, the grinding block 6 can be kept in a horizontal state or a vertical state, so as to achieve dead angle grinding of the wall or the top of the building, and avoid the grinding vibration from tilting the grinding block 6 and affecting the grinding quality.

[0037] In some specific embodiments, such as Figure 7 As shown, in order to reduce the wear of the slide rod 9 and the guide sleeve 7, a plurality of rollers 22 are rotatably distributed on one end of the inner side of each guide sleeve 7 close to the grinding block 6, and the rollers 22 are rollingly connected with the corresponding slide rod 9. When the grinding block 6 is applied to the wall for grinding, the inner side of the slide rod 9 away from the grinding block 6 will have a greater friction force on the guide sleeve 7, thereby causing wear. The setting of the rollers 22 can reduce the friction between the guide sleeve 7 and the slide rod 9, and increase the service life of the guide sleeve 7 and the slide rod 9.

[0038] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0039] During actual work, the base 1 is fixed horizontally on the ground, the lifting structure 2 drives the grinding block 6 to grind different heights, and the motor 12 is started. The motor 12 drives the irregular disc-shaped fan-shaped block 11 to rotate. The rotation of the fan-shaped block 11 can drive the driving wheels 10 on both sides to move left and right while rolling. Since the driving wheel 10 is rotatably connected to the movable plate 8, the movable plate 8 can drive the sliding rods 9 at both ends to slide back and forth along the guide sleeve 7, so that the movable plate 8 can drive the grinding block 6 to reciprocate left and right to grind the wall. Since the grinding block 6 is a square block and the movement state is reciprocating left and right, the wall can be fully polished to avoid grinding dead corners, and a plurality of rollers 22 are rotatably distributed on the inner side of the guide sleeve 7 near the end of the grinding block 6, so that the sliding friction is converted into rolling friction, thereby reducing the wear of the sliding rod 9 and the guide sleeve 7.

[0040] After the vertical wall is polished, the driving rod 19 is pulled by hand to make the plug plate 17 and the plug plate 2 18 slide away from the support plate 5, and the limit of the plug plate 17 on the rear side of the support plate 5 is released, and the plug plate 17 and the plug plate 2 18 are pulled until they do not block the rotating support plate 5. At this time, the telescopic rod 20 is extended, the spring is in a stretched state, and the motor 21 is started. The motor 21 drives the slider 15 connected to the rotating rod 14 to make a circular motion. The slider 15 can slide along the arc-shaped sliding hole 16. Since the slider 15 is fixedly connected to the support plate 5, the support plate 5 also rotates. Movement, so that the slider 15 rotates to the other end of the arc-shaped sliding hole 16, and the motor 2 21 is stopped. At this time, the support plate 5 has rotated ninety degrees, and the driving rod 19 is released. Due to the resilience of the spring, the plug plate 1 17 and the plug plate 2 18 are reset. The plug plate 2 18 is now in contact with the upper surface of the support plate 5, and the support plate 5 is limited. By setting the plug plate 1 17 and the plug plate 2 18 to limit the angle of the grinding block 6, the grinding block 6 can be kept in a horizontal state or a vertical state, so as to achieve dead angle grinding of the wall or the top of the building, and avoid the grinding vibration from tilting the grinding block 6 and affecting the grinding quality.

[0041] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
