The purpose of the present invention can be realized by following technical proposal: the medical chaise longue of a kind of dental, including chair body, the front end of described chair body is connected to the up-down adjustment headrest of rectangle, it is characterized in that, described medical treatment chaise longue also includes left and right adjusting headrest, the cross section of this left and right adjusting headrest is curved, described up-down adjustment headrest offers rectangular indentation, it is respectively provided with connection axle in the middle part of the two ends end face of described left and right adjusting headrest, this two connections axle is rotationally connected on the front and back inwall of rectangular indentation respectively, the side of described up-down adjustment headrest is along being rotatably connected to rocking handle, it is provided with when rocking handle rotates can to drive the driving member of left and right adjusting headrest swing between described rocking handle and left and right adjusting headrest, the locating part of restriction left and right adjusting headrest hunting range it is provided with between described up-down adjustment headrest and left and right adjusting headrest.
People lies on chair body, head pillow is on left and right adjusting is rested the head on, staff is positioned at the sidepiece of chair body, hold rocking handle and rotate the swing that can pass through driving member control left and right adjusting headrest, therefore staff can observe oral cavity while regulating, and uses convenient, and locating part can limit the hunting range of left and right adjusting headrest, avoiding head to be over-torqued, safety is higher.
In the medical chaise longue of above-mentioned dental, described driving member includes gear and tooth bar, in described up-down adjustment headrest, there is installation cavity, described rocking handle and connection axle all stretch in installation cavity, described gear is connected in the inserting end connecting axle, described tooth bar vertically regulates headrest width and is slidably connected in installation cavity, and described gear is positioned at above tooth bar and is meshed with tooth bar, and described rocking handle is connected with rack gear.Driving tooth bar to move back and forth along its length by rocking handle, tooth bar moves and can rotate by driven gear, and namely band is dynamically connected axle reciprocating rotary, it is achieved the left and right reciprocally swinging of left and right adjusting headrest.
In the medical chaise longue of above-mentioned dental, described rocking handle stretches into one end of installation cavity and is fixed with screw rod, the width that the length direction of this screw rod is rested the head on up-down adjustment is identical, and described screw rod is bolted with adapter sleeve, and above-mentioned tooth bar is connected in the top of adapter sleeve lateral wall.Screw rod is moved by adapter sleeve band carry-over bar, simple in construction, and degree of regulation is high.
In the medical chaise longue of above-mentioned dental, being fixed with two axis of guides, described adapter sleeve lateral wall is fixed with two fairleads in described installation cavity, this two fairlead is symmetrical arranged, and fairlead described in two is slidably located on two axis of guides respectively.Fairlead coordinates with the axis of guide so that adapter sleeve moves more stable.
In the medical chaise longue of above-mentioned dental, described locating part includes two gag lever posts, one end of this two gag lever post is respectively hinged on the inwall of rectangular indentation front end, and two gag lever post be positioned at the two ends of rectangular indentation front end side wall, described left and right adjusting headrest front edge offers the stopper slot of two arcs along its length, the other end of gag lever post described in two is respectively provided with limited post, and the sliding plug respectively of limited post described in two is in two stopper slots.When left and right adjusting headrest is rocked to extreme position, gag lever post can hold left and right adjusting headrest, it is to avoid left and right adjusting is expanded and swung excessively.
Compared with prior art, the medical chaise longue of this dental has the advantage that
1, owing to staff is positioned at the sidepiece of chair body, hold rocking handle and rotate the swing that can pass through driving member control left and right adjusting headrest, therefore staff can observe oral cavity while regulating, use convenient, and locating part can limit the hunting range of left and right adjusting headrest, avoiding head to be over-torqued, safety is higher.
2, owing to being provided with locating part between up-down adjustment headrest and left and right adjusting headrest, it is possible to the hunting range of restriction left and right adjusting headrest, it is to avoid head is over-torqued, and safety is higher.
