The specific embodiment
1-6 further specifies the present invention in conjunction with accompanying drawing:
The core apparatus of engagement disc type seat angle adjustor in a kind of smooth tooth section of the present invention comprises disk 1, torsion spring 2, two little tooth plates 3, circular tooth disk 6, involucrum 7, two little shifting blocks 4 and big shifting blocks 5; Disk 1 is sleeved on together with circular tooth disk 6, forms a cavity between wherein; The little tooth plate of torsion spring 2, two 3, two little shifting blocks 4 and big shifting block 5 all are assembled in the above-mentioned cavity; Involucrum 7 is sleeved on the periphery of disk 1 and circular tooth disk 6; Like Fig. 1, shown in 2
The inner ring of circular tooth disk 6 is provided with the light tooth section 6-4 of circular tooth disk internally toothed annulus 6-2 and two places symmetry; The cylindrical 6-3 bearing fit of the disk inner cylinder face 1-4 of disk 1 and circular tooth disk 6; The inner plane of disk 1 is provided with two semicolumn boss 1-2 and four disk boss 1-1 that are uniformly distributed with; The lateral surface of disk 1 is provided with the disk positioning boss 1-3 that links to each other with seat.The lateral surface of circular tooth disk 6 is provided with the circular tooth disk positioning boss 6-1 that links to each other with seat.
The outer ring of little tooth plate 3 is provided with the little tooth plate engaging tooth 3-3 that is meshed with the circular tooth disk internally toothed annulus; The peripheral 3-5 that little tooth plate 3 inner rings become hook-shaped 3-1 and hook contacts with big shifting block 5, and the inner ring of little tooth plate 3 is provided with and the outer ring of the little shifting block 4 notch 3-2 that agrees with mutually of shape mutually; As shown in Figure 3
The outer ring 4-1 of little shifting block 4 matches with notch 3-2 on the inner ring of little tooth plate, and the inner ring 4-3 of little shifting block 4 matches with big shifting block 5; As shown in Figure 4
Big 5 one-tenths of shifting blocks are tabular, and its center is provided with a square hole 5-1, and the torsion spring that the outer ring of big shifting block 5 is provided with two places symmetry is installed the symmetrical cut type piece 5-3 that agrees with mutually with little shifting block 4 inner ring 4-3 shapes in notch 5-4 and two places; As shown in Figure 5
One end of torsion spring 2 is circle 2-1 in side's in the torsion spring, and the inner plane that square circle 2-1 is sleeved on disk 1 in this torsion spring is provided with on two semicolumn boss 1-2; The other end of torsion spring 2 is torsion spring hook 2-2, and the outer ring that this torsion spring hook 2-2 is installed in big shifting block 5 is provided with in the torsion spring installation notch 5-4.
Principle of work of the present invention: the outside is given 5 one clws moments of torsion of big shifting block in advance; Big shifting block 5 under the effect of torsion spring 2 preset torques, clickwise, the inner ring 4-3 that cut type piece 5-3 promotes each little shifting block 4 in its big shifting block 5 clockwise rotates; The outer ring 4-1 of little shifting block 4 promotes little tooth plate 3 notch 3-2 and clockwise rotates; Each little tooth plate engaging tooth and circular tooth disk internally toothed annulus are combined closely, and recliner gets into lock dentation attitude like this, and back of seat is in a relative fixed position.Recliner lock dentation attitude is the normality of this core apparatus.
When giving 5 one C.C.W. power of big shifting block; The big shifting block 5 of anticlockwise motion; The hook 3-1 that cut type piece 5-3 in the big shifting block 5 drives little tooth plate 3 rotates counterclockwise, and the notch 3-2 of little tooth plate wears moving little shifting block 4 outer ring 4-1 conter clockwises motions, and little tooth plate 3 is to central slide; Leave the engagement with circular tooth disk tooth portion, removed constraint circular tooth disk; At this moment, the chair back can be adjusted to proper angle on demand.Big shifting block is automatically pushed little shifting block, little tooth plate to circular tooth disk again under the effect of torsion spring, be engaged with once more, and this device returns to lock dentation attitude again.So just accomplished the process of backrest seat adjustment.
