[0030] The following is a detailed description of the implementation details of the technical solution of the embodiment of the present utility model:

[0031] First of all, it should be noted that the liftable rotating arm device provided by the present invention is used in dental surgical equipment, wherein one end of the first rotating unit 2 is fixed on the pipe, and the second rotating unit 5 is fixedly connected to the tool tray, and the two ends of the straight arm 1 are respectively connected to the first rotating unit 2 and the second rotating unit 5. That is to say, as long as the straight arm 1 is adjusted so that the straight arm 1 rotates, the position of the tool tray can be adjusted. The doctor can adjust the position of the tool tray to the desired position according to actual needs, which is convenient for the doctor to perform dental treatment and other operations.

[0032] According to one aspect of the present invention, a liftable arm device is provided, which includes: a straight arm 1, a first rotating unit 2, a first connecting rod 3, a second connecting rod 4 and a second rotating unit 5; the two ends of the straight arm 1 are respectively connected to the first rotating unit 2 and the second rotating unit 5; the two ends of the first connecting rod 3 are respectively connected to the first rotating unit 2 and the second rotating unit 5, and the two ends of the second connecting rod 4 are respectively connected to the first rotating unit 2 and the second rotating unit 5; when the first connecting rod 3 and the second connecting rod 4 rotate around the first rotating unit 2 and the second rotating unit 5, they drive the straight arm 1 to rotate; the first rotating unit 2 includes a first rotating arm 21 and a limiting unit 22; the first rotating arm 21 is rotatably connected to the straight arm 1, and the limiting unit 22 is arranged inside the rotating arm, and the limiting unit 22 is used to adjust the angle between the first rotating arm 21 and the straight arm 1 and fix the connection relationship between the first rotating arm 21 and the straight arm 1 after adjustment.

[0033] Specifically, if Figures 1-4 As shown, the two ends of the first connecting rod 3 are respectively connected to the first rotating unit 2 and the second rotating unit 5, and the two ends of the second connecting rod 4 are respectively connected to the first rotating unit 2 and the second rotating unit 5; when the first connecting rod 3 and the second connecting rod 4 rotate around the first rotating unit 2 and the second rotating unit 5, the straight arm 1 is driven to rotate.

[0034] The rotatable connection between the straight arm 1, the first rotating unit 2, the first connecting rod 3, the second connecting rod 4, and the second rotating unit 5 allows the straight arm 1 to rotate, thereby adjusting the angle between the first rotating arm 21 and the straight arm 1, that is, the straight arm 1 can be adjusted in a liftable manner. The second rotating unit 5 can be fixedly connected to the tool tray, so that the position of the tool tray can be adjusted by rotating the straight arm 1. At the same time, the angle between the first rotating arm 21 and the straight arm 1 can be adjusted by the limiting unit 22, and the connection between the first rotating arm 21 and the straight arm 1 is fixed after the adjustment, making the entire liftable rotating arm device more stable and reliable during the adjustment process.

[0035] In one embodiment of the present application, the limiting unit 22 includes a spring 221, a rotating shaft unit 222 and a mosaic unit 223, the spring 221 and the rotating shaft unit 222 are both fixed on the first rotating arm 21, the mosaic unit 223 is rotatably connected to the rotating shaft unit 222, and is fixedly connected to the spring 221; the mosaic unit 223 is used to adjust the angle of the first rotating arm 21 so that the straight arm 1 can rotate around the first rotating arm 21.

[0036] Specifically, the spring 221 is fixed to the first rotating arm 21 by fasteners such as screws, and the shaft unit 222 is also fixed to the first rotating arm 21, and is fixedly connected to the spring 221 by the interlocking unit 223. That is, the spring 221 in the stretched state cannot be easily rotated by the special structure of the interlocking unit 223. The first rotating arm 21 can only be rotated when the external force is large enough. This ensures that the straight arm 1 will not rotate easily after the angle is adjusted, thereby ensuring the stability and reliability of the tool tray.

[0037] In one embodiment of the present invention, the interlocking unit 223 includes a wedge piece 2231 and a gear piece 2232; the wedge piece 2231 is fixedly connected to one end of the spring 221 and is connected to the rotating shaft unit 222; the gear piece 2232 is detachably connected to the wedge piece 2231 and is connected to the rotating shaft unit 222.

[0038] The rotating shaft unit 222 includes a first rotating shaft 2221 and a second rotating shaft 2222 . The first rotating shaft 2221 is connected to the gear member 2232 and the first connecting rod 3 , respectively. The second rotating shaft 2222 is connected to the wedge member 2231 and the second connecting rod 4 , respectively.

[0039] The gear part 2232 is provided with a plurality of gear gaps 224, and the wedge-shaped part 2231 can be detachably connected to each of the gear gaps 224. When the wedge-shaped part 2231 abuts against the gear gap 224, the first rotating arm 21 is fixedly connected to the straight arm 1. When the wedge-shaped part 2231 leaves the gear gap 224, the first rotating arm 21 can be reset to readjust the angle between the first rotating arm 21 and the straight arm 1.

[0040] Specifically, the gear member 2232 is provided with three gear slots 224, and the wedge-shaped member 2231 is provided with a gear head 225 that engages with the gear slots 224. The engagement of the gear head 225 with the gear slots 224 prevents the first rotating arm 21 from rotating easily, thereby ensuring that the straight arm 1 is not easily rotated. The gear head 225 can only be adjusted in angle from bottom to top in the order of the gear slots 224. When the gear head 225 leaves the topmost gear slot 224, that is, the third gear slot 224, the gear head 225 moves in the deformation direction under the elastic force of the spring 221, that is, it is reset. This allows the angle between the first rotating arm 21 and the straight arm 1 to be the minimum adjustable angle. At this time, the first connecting rod 3 and the second connecting rod 4 are in contact through the limiting groove 6, so that the angle between the first rotating arm 21 and the straight arm 1 can only be adjusted to a larger angle direction. As a result, the gear head 225 can once again adjust the angle between the three gear slots 224.

[0041] In one embodiment of the present invention, a limiting groove 6 is formed between the first connecting rod 3 and the second connecting rod 4. When the angle between the first rotating arm 21 and the straight arm 1 reaches the maximum adjustable angle or the minimum adjustable angle, the first connecting rod 3 abuts against the second connecting rod 4 for limiting.

[0042] The maximum adjustable angle can be determined based on actual conditions. That is, when the gear head 225 is located at the third gear gap 224, which is the uppermost gear gap 224, the angle between the first rotating arm 21 and the straight arm 1 reaches the maximum adjustable angle. Conversely, when the gear head 225 is located at the first gear gap 224, which is the lowermost gear gap 224, the angle between the first rotating arm 21 and the straight arm 1 reaches the minimum adjustable angle. The first connecting rod 3 and the second connecting rod 4 abut against each other to limit the position and improve stability and reliability.

[0043] In one embodiment of the present invention, the second rotating unit 5 further includes a second rotating arm 51 and a rotating shaft unit 52; the second rotating arm 51 is rotatably connected to the straight arm 1, and the rotating shaft unit 52 is respectively connected to the first connecting rod 3 and the second connecting rod 4.

[0044] In one embodiment of the present invention, the rotation axis unit 52 includes a first rotation axis 521 and a second rotation axis 522, the first rotation axis 521 and the second rotation axis 522 are both arranged on the second rotation arm 51, and the first rotation axis 521 is connected to the first connecting rod 3, and the second rotation axis 522 is connected to the second connecting rod 4.

[0045] Specifically, the position and angle of the tool tray can also be adjusted through the second rotating unit 5, so that the tool tray can be adjusted at multiple angles and dimensions, thereby improving the adjustability of the tool tray and making it more convenient for doctors to adjust the position.

[0046] In one embodiment of the present invention, the length of the straight arm 1 is 50 cm to 100 cm, and the length of the rotating arm is 10 cm to 20 cm.

[0047] Specifically, the length of the straight arm 1 ranges from 50 cm to 100 cm, and the length of the rotating arm ranges from 10 cm to 20 cm.

[0048] In summary, the present invention enables the straight arm 1 to rotate through the rotatable connection between the straight arm 1, the first rotating unit 2, the first connecting rod 3, the second connecting rod 4 and the second rotating unit 5, thereby adjusting the angle between the first rotating arm 21 and the straight arm 1, that is, the straight arm 1 can be adjusted in a liftable manner. The second rotating unit 5 can be fixedly connected to the tool tray, so the position of the tool tray can be adjusted by rotating the straight arm 1. At the same time, the angle between the first rotating arm 21 and the straight arm 1 can be adjusted through the limiting unit 22, and the connection between the first rotating arm 21 and the straight arm 1 is fixed after the adjustment, so that the entire liftable rotating arm device is more stable and reliable during the adjustment process, thereby improving stability.

It is readily understood that the processes illustrated in the above-mentioned figures do not indicate or limit the temporal order of these processes.
