Description

Lifting operation crank of medical rocking bed

Technical Field

The utility model relates to a medical equipment technique especially relates to a technique of the lift operation crank of medical shaking table.

Background

Sickbeds in hospitals are mostly shaking tables, movable bed boards capable of being turned over up and down and lifting mechanisms used for driving the movable bed boards to be turned over up and down are arranged on bed frames of the shaking tables, and the lifting mechanisms are controlled through rocking handles.

The lifting operation crank of the medical shaking table is of a foldable structure, and comprises a main handle and a grab handle, one end of the main handle is connected with a rotating shaft of the lifting mechanism, the grab handle is installed at the other carbonyl of the main handle, the grab handle can pivot relative to the main handle, the grab handle pivots to the state perpendicular to the main handle during operation, the main handle can be shaken, so that the rotating shaft of the lifting mechanism is driven to rotate, the grab handle pivots to be attached to the main handle after the operation is finished, the folding can be completed, the grab handle cannot transversely protrude under the folding state, and therefore peripheral personnel can be prevented from colliding with the rocking handle.

However, after the operator operates the crank, the operator often forgets to fold and return the handle, so that when the operator passes by the handle, the operator is easy to be injured due to colliding with the handle, and the use safety of the operator needs to be improved.

SUMMERY OF THE UTILITY MODEL

To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a medical shaking table's that the safety in utilization is high lift operation crank is provided.

In order to solve the technical problem, the lifting operation crank of the medical shaking table provided by the utility model comprises a main handle and a grab handle, wherein the main handle and the grab handle are straight handles, the lower end of the main handle is provided with a handle shaft capable of pivoting up and down, the grab handle is coaxially arranged on the handle shaft in a rotatable manner, and the grab handle can pivot upwards along with the handle shaft until the grab handle is attached to the main handle;

the method is characterized in that: the main handle is provided with a warning switch, a buzzer and a battery, and the warning switch and the buzzer are connected in series and then connected to the positive electrode and the negative electrode of the battery to form a warning circuit;

the warning switch is a normally closed reed switch, a magnet is fixed on the grab handle, the arrangement position of the magnet is matched with the arrangement position of the warning switch, so that when the grab handle pivots upwards along with the handle shaft to be attached to the main handle, the magnet can trigger the warning switch to be disconnected, and when the grab handle pivots downwards along with the handle shaft to an included angle between the grab handle and the main handle is larger than 30 degrees, the distance between the magnet and the warning switch is larger than the induction distance of the warning switch to the magnet.

Further, a fluorescent label is attached to the main handle.

The utility model provides a lifting operation crank of medical shaking table through the cooperation of magnet and warning switch, can not receive when folding at the grab handle and indicate operating personnel to pay attention to, can effectively avoid forgetting the phenomenon of receiving and folding the grab handle, has the characteristics that the safety in utilization is high.

FIG. 2 is a front view of a lifting handle of the medical swing bed according to the embodiment of the present invention;

fig. 3 is a circuit diagram of a warning circuit in the lifting handle of the medical rocking bed according to the embodiment of the present invention.

Detailed Description

The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.

As shown in fig. 1-3, the lifting crank for a medical swing bed provided by the embodiment of the present invention comprises a main handle U1 and a handle U2, wherein the main handle and the handle are straight handles, a handle shaft U3 capable of pivoting up and down is disposed at the lower end of the main handle U1, the handle U2 is coaxially mounted on the handle shaft U3 in a rotatable manner, and the handle can pivot up along with the handle shaft to be attached to the main handle;

the method is characterized in that: the main handle U1 is provided with a warning switch K1, a buzzer X1 and a battery (not shown in the figure), and the warning switch and the buzzer are connected in series and then are connected to the positive and negative poles of the battery to form a warning circuit;

the warning switch K1 is a normally closed reed switch, a magnet N1 is fixed on the handle U2, the arrangement position of the magnet N1 is matched with the arrangement position of the warning switch K1, so that when the handle U2 pivots upwards along with the handle shaft to be attached to the main handle U1, the magnet N1 can trigger the warning switch K1 to be disconnected, and when the handle U2 pivots downwards along with the handle shaft until the included angle between the handle U2 and the main handle U1 is greater than 30 degrees, the distance between the magnet N1 and the warning switch K1 is greater than the sensing distance of the warning switch K1 to the magnet N1, and the warning switch K1 is closed.
