Specific implementation mode：

The utility model medical examination bed Fan Bei mechanisms, including bed body 1, the bed body include pedestal 2 and are located on pedestal Liftable bedstead 3, the side of the liftable bedstead 3, which is equipped with, may be reversed backrest 4, and the turnable backrest 4 is rectangle frame Body is equipped with three section guide rails 5 on two frame bar 6 of rectangle framework, wherein above the lower part 501 of three section guide rails 5 and frame bar 6 It is fixedly connected, and the top 502 of three section guide rails is fixedly connected with back pad 7.

It for health, is required for replacing disposable paper in each new one examinee of physical examination, lower surface construction reality can be passed through Existing, two head ends of liftable bedstead 3 are respectively equipped with the first, second deflector roll 8,9, and first, second deflector roll is respectively arranged below with The side of exit roller 10 and collecting roller 11, the exit roller 10 and collecting roller 11 is respectively equipped with rotary electric machine, passes through rotary electric machine Action, realize paper delivery and collection, the rotating speed of two rotary electric machines it is consistent；First, second deflector roll is round metal mast, institute The both ends for stating round metal mast are socketed with bearing 12, and the bearing is located in the bearing block 13 of liftable bedstead 12, wherein close It is the first deflector roll that backrest side, which may be reversed, and the upper end of first deflector roll is higher by bed body surface 5mm, the upper end of the second deflector roll and bed Body flush；It is connected by bearing, keeps conveying paper more smooth, resistance is small, and bed body table is higher by by the upper end of the first deflector roll Face 5mm, upper end and the bed body flush of the second deflector roll, can make conveying paper more steady.

Further, it in order to during turning over the back of the body, prevent the paper at middle part from propping up, is led close to second in above-mentioned turnable backrest 9 side of roller is fixed with plastic-steel bar 14, and plastic-steel bar 14 is passed through for being laid under the disposable paper on liftable bedstead bed surface, should A diameter of 2 centimetres of plastic-steel bar, plastic-steel bar 14 are located at the lower end that backrest may be reversed, and 14 upper end of plastic-steel bar and bed body upper surface Concordantly, therefore, examiner will not have the feeling of protrusion in bed body.

It is equipped with silicagel pad close to the lower surface both sides of 8 one end of the first deflector roll backrest may be reversed, when with achievable down tilt Buffering, noise reduction, the silicagel pad is cylinder, multiple grooves is equipped in its lower surface, more preferably to buffer, noise reduction.

The back of the body is turned in order to realize, above-mentioned turnable backrest lower surface is fixedly connected with a right-angle side of a tripod 15, three The output rod of another right-angle side and an electric cylinder of corner bracket is hinged.

Pedestal 2 includes fixed frame 16 and slidably frame 17 for being located at 16 bottom side of fixed frame, the fixed frame 16 For rectangular frame, it is equipped with the first, second universal caster wheel 18,19 in its 1601 bottom surface of the first short side, at its 1602 bottom of the second short side Face is equipped with third universal caster wheel 20, and the first support in parallel is fixed with close to the first short side 1601 in the rectangular frame Bar 21 is equipped with the second strut 22 in parallel, second strut 22 in the rectangular frame close to the second short side 1602 Both ends there is the sliding slot 23 vertical with its length direction, the bottom surface of two long side of the rectangular frame is equipped with and sliding slot 23 coordinates Sliding rail 24, scalable push rod 25 is equipped between first strut, 21 and second strut 22, is set below second strut There are the four, the 5th universal caster wheels 26,27, the second strut 22, sliding slot 23 and scalable push rod 25 to constitute slidably frame 17.

Further, for reasonable design, above-mentioned scalable push rod 25 includes electric cylinder 2501 and is connected to electric cylinder and stretches Push rod 2502 in outlet, 1302 other end of the push rod are hinged on the second strut 22, and above-mentioned electric cylinder is electrically connected with controller It connects, to drive electric cylinder to act, controller includes positive and negative switch, and when being switched by positive pressure, electric cylinder continues work once electrified, makes Push rod 2502 pushes away length, and when not pressing just switch, electric cylinder dead electricity does not work, and when the negative switch of pressing, electric cylinder persistently obtains Electricity work, makes push rod 2502 shrink, and when not pressing negative switch, electric cylinder dead electricity does not work.

It is elongated or shortened by 2501 driving push rod 2502 of electric cylinder, realizes spacing between the first strut 21 and the second strut 22 Variation, and then realize that bed body side is relatively fixed, other side rotation is easy to use.Pass through 2501 driving push rod of electric cylinder 2502 and bed body rotation, mechanism is simple, reasonable design, and noise is small, and mechanism action is more steady.

Further, in order to keep sliding stability reliable, above-mentioned sliding slot is inverted trapezoidal groove, and the sliding rail is in inverted trapezoidal shape, The upper interior angle of inverted trapezoidal is 60 degree, is conducive to improve the stationarity of sliding using the inverted trapezoidal groove of the angle and reduces noise, And do not allow after being used for a long time easy to wear.

Above-mentioned third universal caster wheel 20, which has, centainly avoids examiner from being sitting in the phenomenon that side generation bed body warps, but should Kind phenomenon still remains, and therefore, is set there are two vertical bar 28 in 1602 bottom surface both side of the second short side, which is plastic cement Block 29, the plastic block bottom surface are densely covered with zigzag（Increase the frictional force with ground）, and plastic block bottom surface is with ground distance 8mm, since each universal caster wheel is plasthetics, has elasticity, therefore, plastic block when user takes or lie upper bed body Bottom surface disappears with ground distance, to which bed body and ground have more supporting points, to avoid bed body unilateral side from warping.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.
