当孕妇需要使用本设备进行休息时,孕妇坐在坐板上,孕妇背靠在靠板上,此时护工启动伺服电机,伺服电机通过第一转轴带动扇形齿轮逆时针转动,当扇形齿轮与齿条啮合时,扇形齿轮带动齿条向左移动,齿条通过滑套带动梯形块向左移动,第一弹簧被拉伸,第一滚轮随着梯形块上侧渐渐升高的坡度带动升降杆在导向杆内向上移动,从而带动靠板以铰接处为原点向上摆动,当扇形齿轮与齿条不啮合时,第一弹簧复位,第一弹簧带动梯形块向右复位,梯形块带动滑套向右复位,第一滚轮随着梯形块上侧渐渐降低的坡度带动升降杆在导向杆内向下移动,从而带动靠板左部以铰接处为原点向下摆动,由此循环往复,便可实现孕妇休息时对孕妇的身体进行放松的作用,当孕妇休息完毕,护工关闭电机即可。When a pregnant woman needs to use this device for rest, the pregnant woman sits on the seat board and her back leans against the back board. At this time, the nurse starts the servo motor, and the servo motor drives the sector gear to rotate counterclockwise through the first rotating shaft. When the bars are engaged, the sector gear drives the rack to move to the left, and the rack drives the trapezoidal block to move to the left through the sliding sleeve, the first spring is stretched, and the first roller drives the lifting rod to move along with the gradient on the upper side of the trapezoidal block. The guide rod moves upwards, thereby driving the support plate to swing upwards with the hinge as the origin. When the sector gear and the rack are not meshed, the first spring resets, and the first spring drives the trapezoidal block to reset to the right, and the trapezoidal block drives the sliding sleeve to the right Resetting, the first roller drives the lifting rod to move downwards in the guide rod along with the gradually decreasing slope on the upper side of the trapezoidal block, thereby driving the left part of the support plate to swing downwards with the hinge as the origin, thus reciprocating, so that pregnant women can rest It can relax the pregnant woman's body at the same time. When the pregnant woman finishes resting, the nurse can turn off the motor.

因为还包括有第二弹簧、踏脚板和橡胶垫,坐板右侧中部连接有第二弹簧,坐板右侧上部铰接有踏脚板,第二弹簧另一端与踏脚板连接,踏脚板右侧上部设有橡胶垫。当孕妇坐在摇椅上休息时,孕妇可以将双腿放在踏脚板上,将双脚放在橡胶垫上,此是孕妇可以通过踩动橡胶垫,使踏脚板以铰接处为原点向下摆动,第二弹簧被压缩,当孕妇不对橡胶垫施力时,第二弹簧复位,第二弹簧带动踏脚板以铰接处为原点向上摆动,从而达到更为舒适的休息体验。Because it also includes the second spring, pedal and rubber pad, the middle part of the right side of the seat is connected with the second spring, the upper part of the right side of the seat is hinged with the pedal, the other end of the second spring is connected with the pedal, and the upper part of the right side of the pedal Features rubber pads. When the pregnant woman sits on the rocking chair to rest, the pregnant woman can put her legs on the footboard and put her feet on the rubber pad. At this time, the pregnant woman can step on the rubber pad to make the footboard swing downward with the hinge as the origin. The second spring is compressed, and when the pregnant woman does not apply force to the rubber pad, the second spring resets, and the second spring drives the footboard to swing upwards with the hinge as the origin, thereby achieving a more comfortable rest experience.

因为还包括有第一轴承座、第二转轴、锥齿轮、第二轴承座、第三转轴、凸轮、第二支杆和第二滚轮,底板上方中部连接有第一轴承座,第一轴承座内过盈连接有第二转轴,第二转轴穿过左右两侧的椅腿,第二转轴左右两端均设有锥齿轮,扇形齿轮前方通过第一转轴连接有锥齿轮,位于扇形齿轮前方的锥齿轮与位于第二转轴左端的锥齿轮啮合,底板上方右侧设有锥齿轮,位于底板上方右侧的锥齿轮与位于转轴右端的锥齿轮啮合,锥齿轮后侧中部连接有第三转轴,第三转轴中部设有凸轮,第三转轴后部设有第二轴承座,第二轴承座后侧连接有第二支杆,第二支杆底端与底板上侧右部连接,踏脚板下侧左部连接有第二滚轮,第二滚轮与凸轮接触。当护工启动伺服电机逆时针旋转时,伺服电机通过第一转轴带动位于扇形齿轮前侧的锥齿轮转动,位于扇形齿轮前侧的锥齿轮带动位于转轴左端的锥齿轮转动,位于转轴左端的锥齿轮通过转轴带动位于转轴右端的锥齿轮转动,从而带动位于凸轮前侧的锥齿轮转动,进而通过第三转轴带动凸轮转动,当凸轮上的凸出部份与第二滚轮底部接触时,第二滚轮带动踏脚板向上摆动,第二弹簧被拉伸,当凸轮上的凸出部份转离第二滚轮底部时,第二弹簧复位,第二弹簧带动踏脚板以铰接处为原点向下摆动,从而实现无需孕妇自己用力便可实现踏脚板自动上下摆动,从而使孕妇达到腿部的放松作用。Because it also includes the first bearing seat, the second rotating shaft, the bevel gear, the second bearing seat, the third rotating shaft, the cam, the second pole and the second roller, the middle part above the bottom plate is connected with the first bearing seat, and the first bearing seat The inner interference connection has a second rotating shaft, and the second rotating shaft passes through the chair legs on the left and right sides, and the left and right ends of the second rotating shaft are provided with bevel gears, and the front of the sector gear is connected with the bevel gear through the first rotating shaft, and the front of the sector gear is located The bevel gear meshes with the bevel gear located at the left end of the second rotating shaft. The bevel gear is arranged on the right side above the base plate. The bevel gear located on the right side above the base plate meshes with the bevel gear located at the right end of the rotating shaft. The middle part of the rear side of the bevel gear is connected with the third rotating shaft. The middle part of the third rotating shaft is provided with a cam, the rear part of the third rotating shaft is provided with a second bearing seat, the rear side of the second bearing seat is connected with a second strut, the bottom end of the second strut is connected with the upper right part of the bottom plate, and The left part of the side is connected with a second roller, and the second roller is in contact with the cam. When the nurse starts the servo motor to rotate counterclockwise, the servo motor drives the bevel gear on the front side of the sector gear to rotate through the first shaft, the bevel gear on the front side of the sector gear drives the bevel gear on the left end of the shaft to rotate, and the bevel gear on the left end of the shaft The bevel gear located at the right end of the rotating shaft is driven to rotate through the rotating shaft, thereby driving the bevel gear located at the front side of the cam to rotate, and then the third rotating shaft drives the cam to rotate. When the protruding part on the cam contacts the bottom of the second roller, the second roller Drive the pedal to swing upwards, the second spring is stretched, when the protruding part on the cam turns away from the bottom of the second roller, the second spring resets, and the second spring drives the pedal to swing downward with the hinge as the origin, thus The step plate can automatically swing up and down without the pregnant woman's own effort, so that the pregnant woman can relax the legs.

因为还包括有凹形板和海绵块,坐板左部上方开有内腔,内腔内底部均匀连接有凹形板,凹形板内底部粘接有海绵块。孕妇可将手机或者保温杯放置在凹形板内,方便休息时物品的搁置,粘接的橡胶块,能够防止底部的摩擦损坏。Because it also includes a concave plate and a sponge block, there is an inner cavity above the left part of the seat plate, the inner bottom of the inner cavity is evenly connected with a concave plate, and the inner bottom of the concave plate is bonded with a sponge block. Pregnant women can place their mobile phones or thermos cups in the concave plate, which is convenient for shelving items during rest, and the glued rubber blocks can prevent friction damage at the bottom.

本发明达到了产科的孕妇除了躺在病床上休息,还能有其它休息方式,有利于孕妇放松的有益效果,本发明通过齿条与扇形齿轮及升降杆与梯形块的配合,使得靠板可以自动上下摆动,实现了摇椅的基本功能,而凸轮与第二滚轮的配合,使得踏脚板可以自动向上或向下摆动,让产妇在休息过程中可以有更加舒适的体验,使孕妇在本设备上休息时得以放松。The present invention achieves that pregnant women in obstetrics can rest in other ways besides resting on the hospital bed, which is conducive to the beneficial effect of relaxing pregnant women. The present invention makes the backing board can be Automatically swing up and down to realize the basic function of the rocking chair, and the cooperation of the cam and the second roller makes the footboard swing up or down automatically, so that the pregnant woman can have a more comfortable experience during the rest process, so that the pregnant woman can rest on this device To relax while resting.
