Two fixed upright posts 24 are arranged on two sides of the small overturning upright post 20, one end of each fixed upright post 24 is fixed on the guardrail locking pipe 7, and the other end of each fixed upright post 24 is fixed on the guardrail transverse pipe 6. The small overturning upright post 20 and the fixed upright post 24 are externally provided with a protective cover 27 for aesthetic reasons.

As shown in fig. 4, the mounting base comprises a U-shaped clamping seat 81 and a clamping seat bottom plate 82 fixed at the bottom of the U-shaped clamping seat by bolts, when the turning-over device is assembled with a common sickbed, the opening of the U-shaped clamping seat 81 is clamped into a longitudinal beam of the bedstead 1 from top to bottom, and the whole turning-over device assembled with the clamping seat bottom plate 82 is fixedly connected with the U-shaped clamping seat 81 by bolts.

The turning plate bracket 11 is provided with two bracket side plates which are arranged in parallel and symmetrically, and the swing rod 12 is in pin joint between the two bracket side plates.

A roll-over stand shaft seat 25 is fixed on the outer side of the roll-over stand side plate 14, and a second through hole 251 corresponding to the first through hole 141 is arranged on the roll-over stand shaft seat 25.

In order to prevent the operator from catching his hand when operating the sliding sleeve 21, the end of the sliding sleeve 21 is further covered with a soft protective cover 26.

Connect respectively on roll-over stand curb plate 14 for three guardrail violently pipe 6, guardrail lock pipe 7 and driven cylinder 5 that are parallel to each other, wherein the effect that the guardrail violently managed 6 is: when a patient lies in bed, the swing rod 12 is upwards supported, and the guardrail transverse tube 6 is positioned above, so that the patient is prevented from falling off from a sickbed. The driven roller 5 is used for supporting the swing rod 12 of the turnover device on one side upwards when a patient needs to turn over the body, at the moment, the driven roller 5 is required to be upwards, and the bed sheet bypasses the driven roller 5 and is wound on the electric roller 3 to provide power for turning over the body of the patient. The middle one is a guardrail locking pipe 7, and after the positions of the guardrail transverse pipe 6 and the driven roller 5 are adjusted, the side plates 14 of the roll-over stand are locked. When the work state needs to be switched, the rotary lock rod 19 is separated from the swing rod 12, so that the side plate 14 of the roll-over stand can rotate freely.

Specifically, when a patient gets on or off the bed, the patient steps on the pedal 15 with his foot, and at this time, the pedal long shaft 4 rotates reversely to drive the tail end of the locking and rotating rod 9 to move downwards, so that the locking and pulling rod 10 moves downwards in the first long hole 111 and the second long hole 112 to separate the locking pin shaft 101 from the slot 121, and the swing rod 12 can rotate freely again under the action of the push rod 13 until the end part of the swing rod 12 connected with the roll-over stand side plate 14 descends to a lower position.

When a patient lies in bed, in order to prevent the patient from falling off the sickbed and other accidents, the swing rod 12 is supported to a high position and is locked by the locking pin shaft 101, the sliding sleeve 21 is adjusted and pulled, the guardrail transverse tube 6 is positioned above the side plate 14 of the roll-over stand when the side plate of the roll-over stand is adjusted, and the driven roller 5 is positioned below the side plate.

Under the normal state that the swing rod 12 supports the guardrail transverse tube 6 upwards, if a patient needs to turn over, the protecting sleeve 26 can be held by hands and dragged to the middle of the guardrail locking tube 7, under the driving of the protecting sleeve 26, the sliding sleeve 21 drives the locking tube sliding column 18 to compress the spring 17 inwards and drives the rotary locking rod 19 to move inwards, and the rotary locking rod 19 can be separated from the dead locking groove 122 on the swing rod 12 and move circularly around the overturning frame trunnion 23 again. When the driven roller 5 is upward, the rotary lock rod 19 meets another locking groove 122, and at the moment, under the pressure of the spring 17, the rotary lock rod 19 is clamped in the locking groove 122 on the swing rod 12. Thereby relocking the roll cage side panels 14. The bed sheet under the body of the patient is connected to the electric roller 3 under the bed by bypassing the driven roller 5, and the electric roller 3 pulls the bed sheet to drag the patient through the driven roller 5 by pressing the control button of the electric roller 3, thereby realizing the automatic operation of turning over the patient.

It should be understood that the above-described specific embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Obvious variations or modifications which are within the spirit of the invention are possible within the scope of the invention.
