Advantageous effects
Compared with the prior art, the invention has the following beneficial effects:
1. the movable bed moves the time and drives gyro wheel and interior rotation of axes to the right, if the movable bed moves too fast, then the centrifugal force grow that the clutch blocks received outwards stretches out and supports the connecting axle, and then make the connecting axle rotate, the back is rotatory, it is rotatory to drive the urceolus through the driving lever, because the eccentric department of urceolus installs the connecting rod, consequently the urceolus passes through the connecting rod and drives slide and buffering subassembly and move right, make the buffering subassembly stretch out right and push up on the limiting plate when the movable bed moves to the rightmost side, cushion the speed of movable bed through the buffering subassembly, effectually avoided because medical personnel operate improperly, lead to the patient on the movable bed to receive the problem of great inertia impact, patient's protection effect has been played.
2. Through setting up connecting axle, interior axle, spring and clutch blocks, only when the activity bed removes at the excessive speed, just can drive the buffering subassembly and move right and stretch out and cushion the protection, when the normal slow speed of activity bed removed, the buffering subassembly can not move right and stretch out, can avoid the buffering subassembly to move right all the time and stretch out, also causes the problem of resistance when moving to the right-hand member under to normal condition, convenient to use.
3. Through setting up connecting axle, urceolus, driving lever and activity groove, only when the connecting axle rotates a period after, the driving lever just can remove to the tip of extrusion activity groove in the activity groove, and then drives the urceolus rotatory, has avoided because of the situation of accident, and the removal is too fast in the interim short time of activity bed, also leads to the buffering subassembly to stretch out, influences the problem of the last removal of activity bed, convenient to use.
4. Through setting up the balancing weight, the urceolus can automatic re-setting under the effect of configuration piece, and the balancing weight also can give the urceolus with power when following the top downwardly rotating simultaneously, has guaranteed that the activity bed removes when too fast, and the buffering subassembly can stretch out, uses reliably.
