Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has schematically shown the quiet articulation structure according to a kind of embodiment of the present utility model.As shown in Figure 1, quiet articulation structure, comprises geared sleeve 1, gear 2, cover plate 3, limiting plate 5, pin 6, handle 7, the first axle 8, the second axle 9 and two clamping plates 4, as shown in the figure, geared sleeve 1 is provided with the first internal tooth 11, as shown in Figure 3, gear 2 is provided with the first external tooth 21 and the second external tooth 22, the first internal tooths 11 are meshed with the first external tooth 21, as shown in Figure 4, cover plate 5 is provided with accommodation space 31, and as shown in Figure 5, clamping plate 4 are provided with the first through hole 44, the second through hole 43, third through-hole 41 and pin activity bit 42, as shown in Figure 6, limiting plate 5 is provided with fourth hole 51, circular groove 52, as shown in Figure 7, handle 7 is provided with the second internal tooth 71, in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, two clamping plates 4 one end clamping limiting plates 5, its other end clamping geared sleeve 1, the first axle 8 connects the first through hole 44 and fourth hole 51, the second axle 9 connects the second through hole 43 and circular groove 52, and gear 2 one end are meshed with geared sleeve 1, and its other end connects third through-hole 41, and the second internal tooth 71 is meshed with the second external tooth 22, and pin 6 is placed in pin activity bit 42.Geared sleeve 1, gear 2, two clamping plates 4, limiting plate 5, pin 6, the first axle 8 and the second axle 9 are placed in accommodating cavity 31.The first axle 8, the second axle 9 are concordant with geared sleeve 1 and on same straight line.
Geared sleeve 1 is provided with the first internal tooth 11, and gear 2 is provided with the first external tooth 21 and the second external tooth 22, and handle 7 is provided with the second internal tooth 71, the first internal tooths 11 and is meshed with the first external tooth 21, and the second internal tooth 71 is meshed with the second external tooth 22.Move handle 7 and rotate, driven gear 2 rotates, gear 2 driven gear cover 1 rotations.When rotation, the first internal tooth 11 engages all the time with the first external tooth 21, and relative position can not change; The second internal tooth 71 engages all the time with the second external tooth 22, and relative position also can not change.So while rotation, can not sound, realize quiet rotation.
Cover plate 5 is provided with accommodation space 31, and geared sleeve 1, gear 2, two clamping plates 4, limiting plate 5, pin 6, the first axle 8 and the second axle 9 are placed in accommodating cavity 31.Geared sleeve 1, gear 2, two clamping plates 4, limiting plate 5, pin 6, the first axle 8 that cover plate 5 makes are avoided contacting with the external world in being sealed in accommodating cavity 31 with the second axle 9, play dustproof effect.
