In mode, it is connected between power mounting seat 21 and the lifting drive block 25 via four gas bars 29, four 29 liang of gas bars
Two are evenly distributed on the opposite sides of lifting drive block 25, when the bearing (ball) cover 26 of the lifting sidepiece of drive block 25 is rotated by driving
When dead axle 70 drives scissor lift 10 elevating movement of unit, gas bar 29 can consolidate 25 each side of lifting drive block, prevent lifting from driving
Motion block 25 is offset, and strengthens the stability of total.Now, the slip for lifting drive block 25 drives scissor lift unit 10
Lifting, due to bottom activity set support lifters bottom be provided with it is lower connection guide assembly 40, and bottom activity set
Support lifters bottom is connected with the sliding block 61 in lower connection guide assembly 40 by fixed rotary shaft 28, so, work as scissors
When lifting unit 10 rises, the sliding block 61 in lower connection guide assembly 40 drives the support lifters that bottom activity is set the bottom of towards
The support lifters direction of portion's fixed setting is gently slided along sliding guide rail 62, when scissor lift unit 10 declines, lower connection
The support lifters that the support lifters that sliding block 61 in guide assembly 40 drives bottom activity to set are fixedly installed towards bottom
Opposite direction is gently slided.Similarly, the upper connection guide assembly 50 that the top of the support lifters 11 of bottom fixed setting is set,
The top of guide assembly 50 is connected on this for carrying bed body panel, when the support lifters 11 of bottom fixed setting lift
When, the top of the support lifters 11 of bottom fixed setting slides along the upper guide direction for connecting guide assembly 50, and
And the 62 concordant horizontal plane of sliding guide rail in upper connection guide assembly 50 is set, so when the support liter of bottom fixed setting
When dropping the lifting of part 11, it can ensure that bed body panel inclined lift is moved.
Hospital bed body support frame provided by the utility model, by providing a kind of hospital bed body support frame, the medical bed body branch
The bottom fixed setting of the support lifters in two support lifters in frame, the bottom of another support lifters is lived
It is dynamic to set so that the pin joint 13 of two support lifters back and forth movement on the straight line for favour horizontal plane direction,
Medical bed body inclined lift is finally realized, the up-down mode reduces bed body in the height to reduce as far as possible so that patient can
Lie easily onto bed, it is very convenient and practical.And compared with horizontal lead screw propulsion mode, in the utility model institute offer scheme,
The space that base needs is smaller, i.e., base needs length smaller, when specific clinical, because the space of hospital is extremely limited,
The proportioning of other equipment can more be optimized.Meanwhile horizontal lead screw propulsion mode causes the pushing torque mistake of power drive needs
Greatly, after using this inclined lift mode instead, any described of the first half of pin joint 13 positioned at two support lifters is passed through
Articulated telescopic dynamic structure 20 in lifters is supported, pushing torque length is substantially reduced, saves using energy source.In addition, this
Flexible dynamic structure 20 includes Motorized drive unit 22, the ball screw 24 with the Motorized drive unit 22 drive connection, sliding
The dynamic lifting drive block 25 being placed on the ball screw 24, the lifting drive block 25 and the scissor lift structure via
One driving rotates dead axle 70 and is connected, and drives the ball screw 24 to rotate by Motorized drive unit 22, drives the lifting
Drive block 25 slides on ball screw 24, and linkage driving rotates dead axle 70 and drives the scissor lift structures slope to lift, by
Reduce in the pushing torque length of the dynamic structure 20 that stretches so that the lifting of hospital bed body support frame is more steady.
The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to described above.Thus, some details in embodiment should not be formed to this practicality
New restriction, the utility model will be used as protection domain using the scope that appended claims define.
