Referring to fig. 1 to 7, a rotating assembly according to an embodiment of the first aspect of the present invention includes a second rotating arm 100, a rotating shaft 200, a first rotating arm 400, a washer 500, and a nut 600. The first rotation arm 400 is provided with a first through hole 430 (refer to fig. 2). One end (for example, the upper end, see fig. 5) of the rotating shaft 200 is inserted into the first through hole 430, and the rotating shaft 200 is rotatably or fixedly connected to the second rotating arm 100. The nut 600 is threadedly coupled to one end (e.g., upper end, see fig. 5) of the rotating shaft 200, and the nut 600 can abut against the first rotating arm 400 to limit the movement of the first rotating arm 400 away from the rotating shaft 200. The washer 500 is sleeved on the rotation shaft 200, the washer 500 is located between the nut 600 and the first rotation arm 400, the washer 500 is made of polyoxymethylene, the washer 500 includes at least one tapered ring 510 (see fig. 7), the tapered rings 510 are sequentially arranged along the axial direction, and the tapered rings 510 can elastically deform along the axial direction.
According to the utility model discloses rotating assembly has following beneficial effect at least: the washer 500 is located between the nut 600 and the first rotating arm 400, the washer 500 comprises at least one conical ring 510, each conical ring 510 can elastically deform along the axial direction, therefore, when the rotating assembly is assembled, the conical ring 510 is pre-tightened by the nut 600, a basic deformation amount of the conical ring 510 can be caused, so that the first rotating arm 400 and the second rotating arm 100 are kept pre-tightened, and the first rotating arm 400 is not easy to rotate relative to the second rotating arm 100; in addition, the washer 500 is made of polyoxymethylene, which has good wear resistance, and after the rotating assembly is used for a long time, the washer 500 is not easily worn, the washer 500 can still maintain the pre-tightening between the first rotating arm 400 and the second rotating arm 100, and the rotating assembly can maintain the pre-tightening for a long time.
In addition, the gasket 500 of polyoxymethylene material has good fatigue resistance and can be compressed 1 ten thousand to 5 thousand times without deformation. In addition, the nut 600 is pre-tightened by the washer 500, which is advantageous to improve the problem of noise generated by the direct contact between the nut 600 and the first rotation arm 400.
Specifically, the tapered ring 510 refers to a ring whose width gradually increases in the axial direction, and the tapered ring 510 may be a circular cone ring.
Specifically, the number of the tapered rings 510 may be 1, 2, 3 or other numbers, and the greater the number of the tapered rings 510, the better the elasticity of the gasket 500 and the greater the compressibility of the gasket 500.
Referring to fig. 2 and 5, in some embodiments of the present invention, the outer circumferential surface of the nut 600 is provided with a limiting ring 610, the first rotating arm 400 is provided with a first annular surface 410 and a second annular surface 420, and a distance D between the first annular surface 410 and the limiting ring 610 1 Is smaller than the distance D between the second annular surface 420 and the retainer ring 610 2 . Two opposite surfaces of the gasket 500 respectively abut against the retainer ring 610 and the second annular surface 420, and the first annular surface 410 abuts against the retainer ring 610 to limit the maximum compression amount of the gasket 500.
The distance D between the first annular surface 410 and the stop collar 610 1 Is smaller than the distance D between the second annular surface 420 and the retainer ring 610 2 This illustrates the first ring shapeThe face 410 is closer to the stop collar 610. When the nut 600 is installed, since the first annular surface 410 can abut against the stop ring 610, the washer 500 is not compressed even if the nut 600 is continuously tightened, thereby reducing the probability that the washer 500 is crushed.
Referring to fig. 5, in a further embodiment of the invention, the distance D between the first annular surface 410 and the stop collar 610 1 0.1 to 0.3 mm.
When the distance between the first annular surface 410 and the retainer ring 610 is zero, it indicates that the retainer ring 610 directly abuts against the first annular surface 410, and the first rotating arm 400 directly abuts against the second rotating arm 100. At this time, the friction between the first annular surface 410 and the retainer ring 610 is large, the friction between the first rotating arm 400 and the second rotating arm 100 is large, and the first rotating arm 400 and the second rotating arm 100 are difficult to rotate relatively, so that the rotating assembly is difficult to normally use.
By defining the distance D between the first annular surface 410 and the stop collar 610 1 The distance between the stopper ring 610 and the first annular surface 410 is 0.1 to 0.3mm, and the first rotary arm 400 and the second rotary arm 100 are biased by the washer 500, so that a certain distance may exist between the first rotary arm 400 and the second rotary arm 100 (when the compression amount of the washer 500 is increased, the distance between the first rotary arm 400 and the second rotary arm 100 is also increased), and thus the first rotary arm 400 and the second rotary arm 100 may normally rotate relative to each other.
When the distance D between the first annular surface 410 and the retainer ring 610 is smaller 1 When the compression amount is too small, the compression amount of the washer 500 is too large, and the frictional force between the first and second swing arms 400 and 100 is too large. When the distance D between the first annular surface 410 and the stop collar 610 is smaller 1 If the friction force is too large, the friction force between the first swing arm 400 and the second swing arm 100 is too small, and the first swing arm 400 is easily swung with respect to the second swing arm 100.
Specifically, the distance D between the first annular surface 410 and the stop collar 610 1 0.1mm, 0.2mm or 0.3 mm.
Referring to fig. 2, in some embodiments of the invention, the stop collar 610 is provided with at least one notch 611, the notch 611 being used to tighten or loosen the nut 600. Thus, by providing the notch 611, the nut 600 can be easily tightened or loosened, and thus the assembly and disassembly of the rotating assembly can be easily accomplished.
