Detailed description of the invention
Also by reference to the accompanying drawings this utility model is described in further detail below by specific embodiment.
A kind of nursing bed of headrest adjustable as shown in Figure 1, comprise second body 10 and the 3rd body 30, pivot 20 is configured with between described second 10 and the 3rd body 30,3rd bed board 30 can rotate and the angle α of the 3rd bed board 30 and the second bed board 10 is diminished, and this angle α can change between about 0 ~ 90 °.
Shown in composition graphs 2 and Fig. 5, the gear 31 that it is axle center that the inner of the 3rd bed board 30 is provided with this pivot 20.The outer end of this second bed board 10 is positioned at the ratchet 40 with moving tooth 41 that inboard hinge has and this gear 31 matches of this pivot 20, and this ratchet 40 is furnished with the torsion spring 60 making this moving tooth 41 compress this gear 31.That is, this moving tooth 41 can withstand on certain tooth of this gear 31, thus this angle α is fixed.
Shown in composition graphs 3 and Fig. 4, this pivot 20 is arranged with reseting plate 50.This reseting plate 50 has and is positioned at the first projection 51 inside this pivot 20 and the second projection 52, is positioned at the 3rd projection 53, the 4th projection 54 outside this pivot 20.Wherein, this first projection 51 be positioned at the upside of this moving tooth 41 and this moving tooth 41 cannot be crossed, downside that this second projection 52 is positioned at this moving tooth 41 and this moving tooth 41 cannot be crossed.3rd projection 53 be positioned at the downside of the inner of the 3rd bed board 30 and the inner of the 3rd bed board 30 cannot be crossed, upside that the 4th projection 54 is positioned at the inner of the 3rd bed board 30 and the inner of the 3rd bed board 30 cannot be crossed.Now, 3rd bed board 30 can adopt steel pipe to prepare, thus the inner of the 3rd bed board 30 can have " U " shape groove, and this reseting plate 50 is positioned at this " U " shape groove, and then make the 3rd projection 53 and the 4th projection 54 can lay respectively at the upper side and lower side of the inner of the 3rd bed board 30 and the inner of the 3rd bed board 30 cannot be crossed.Like this, when the angle α that the 3rd bed board 30 is rotated upwardly to the 3rd bed board 30 and this second bed board 10 is approximately 90 °, inner upside touching the 4th projection 54 of the 3rd bed board 30 thus drive this reseting plate 50 to rotate counterclockwise and then this first projection 51 is against on the upper side of this moving tooth 41, this moving tooth 41 cannot reset and continue to withstand on certain tooth of this gear 31, then the 3rd bed board 30 can downwards without the reset hindered, and also namely this angle α is tending towards 0 ° again; When the 3rd bed board 30 angle α be rotated down to the 3rd bed board 30 and this second bed board 10 is approximately 0 °, inner downside touching the 3rd projection 53 of the 3rd bed board 30 thus drive this reseting plate 50 to rotate clockwise and then this second projection 52 promotes the downside of this moving tooth 41, namely this moving tooth 41 is again subject to the effect of this torsion spring 60 and can again withstands on certain tooth of this gear 31, makes the 3rd bed board 30 can stay in the position of certain setting.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
