Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties and different uses.

[0003] Among them, curved furniture and the curved shape of the space can create a comfortable visual design aesthetic. No matter how big or small the space is, curved furniture can create a stylish space layout in a soft and relaxed way. In a compact space, the curved shape is the perfect solution to avoid corners and accidental bumps. In a spacious living space, curved furniture can become a unique and eye-catching focus, so the market demand for curved furniture is growing.

[0004] The curved surface sander is one of the commonly used equipment for grinding and polishing the inside and outside of the curved wooden circle. The curved surface sander includes a driving roller and a grinding roller, wherein the driving motor of the driving roller can be pushed by a horizontal slide to move horizontally to adjust the distance between the driving roller and the grinding roller, and can achieve the grinding of boards of different thicknesses. At the same time, the driving motor of the grinding roller can move up and down through a vertical slide to fully grind the curved surface of the board;

[0005] However, in actual use, since the curved furniture accessories are attached to the surface of the workbench, the curved furniture accessories are in contact with the bottom of the grinding roller. When grinding a large number of thin curved furniture accessories, the bottom of the grinding roller will be severely worn, which is not conducive to the uniform grinding of other curved furniture accessories in the later stage. Based on this, a curved furniture grinding device is provided. Utility Model Content

[0034] The lifting unit includes a support plate 201, a connecting arm 202, a lifting rod 203, a connecting plate 204, and a lifting base 205;

[0035] Two support plates 201 are provided and are located on the top of the chassis body 101. The two support plates 201 are symmetrically distributed at both ends of the dust cover 104 with the dust cover 104 as the center. The connecting arm 202 is fixed to one side of the support plate 201, and the lifting rod 203 is fixed to the bottom of the connecting arm 202.

[0036] The lifting base 205 is fixedly installed on one side of the outer wall of the chassis body 101, the lifting rods 203 penetrate the upper and lower ends of the lifting base 205, and the connecting plate 204 is fixed to the bottom ends of the two lifting rods 203;

[0037] The support plate 201 is used to provide support for the arc-shaped furniture accessories, and the height of the support plate 201 can be adjusted by moving the lifting rod 203 up and down along the lifting base 205;

[0038] The locking unit includes a first fixing block 206, a second fixing block 207, a rotating rod 208, an arc-shaped hook 209, and a locking slot 210;

[0039] The first fixing block 206 and the second fixing block 207 are symmetrically fixed to one side of the outer wall of the lifting base 205, the rotating rod 208 passes through the two sets of the first fixing block 206 and the second fixing block 207, and the arc hook 209 is fixed to the outer wall side of the rotating rod 208 and distributed between the first fixing block 206 and the second fixing block 207;

[0044] In this embodiment: when grinding the arc-shaped furniture accessories, the arc-shaped furniture accessories can be moved in contact with the upper surface of the support plate 201, and the driving roller 102 can provide driving force for the movement of the arc-shaped furniture accessories. The rotation direction of the grinding roller 103 is opposite to that of the driving roller 102. The grinding roller 103 can grind the surface of the arc-shaped furniture accessories, and the dust cover 104 is connected to the external dust collection device through a hose to suck the grinding dust (it should be noted that this solution only improves the external structure of the chassis body 101, and does not involve the driving structure of the driving roller 102 and the grinding roller 103, so the driving structure inside the chassis body 101 is not described in detail);

[0045] In order to avoid excessive wear of the grinding roller 103 due to long-term grinding at the same position, the height of the support plate 201 can be adjusted. The operation steps are as follows:

[0046] Turn any one of the knobs 211 to rotate the rotating rod 208 to loosen the threaded column block 213 and the threaded hole groove 212. At this time, the arc hook 209 is driven by the rotating rod 208 to move and rotate, and finally the arc hook 209 is separated from the locking groove 210, and the lifting rod 203 is unlocked at this time;

[0047] After that, the support plate 201 can be pulled up and down to move the lifting rod 203 synchronously. When the support plate 201 is adjusted to a suitable height, the knob 211 is rotated in the opposite direction to rotate the rotating rod 208 to drive the threaded column block 213 and the threaded hole groove 212 to be tightened. The arc hook 209 is rotated and inserted into another locking groove 210. In this way, the height of the lifting rod 203 is fixed, that is, the height of the support plate 201 is fixed at this time.

[0048] The support plate 201 is height-adjustable to support arc-shaped furniture accessories placed at different heights, so that the arc-shaped furniture accessories are in contact with the grinding roller 103 at different heights, so that the overall wear degree of the grinding roller 103 remains close, effectively improving the service life of the grinding roller 103.

[0049] Please refer to Figures 2 to 4 The horizontal width of the arc hook 209 is smaller than the horizontal width of the locking slot 210, and is used to provide a movable space for the horizontal movement generated when the threaded column block 213 and the threaded hole slot 212 are tightened or loosened.

[0050] In this embodiment: during the process of tightening or loosening the threaded column block 213 and the threaded hole groove 212, the rotating rod 208 will move horizontally. The structure in which the horizontal width of the arc hook 209 is smaller than the horizontal width of the locking groove 210 can ensure stable locking and unlocking of the arc hook 209 and the locking groove 210.

[0051] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
