Detailed Description

The controller key box 1 is manufactured by injection molding of a plastic mold, the sliding tube 7 is manufactured by a metal tube or a plastic tube matched with the linear bearing 6, the metal sliding rod 5 is manufactured by electroplating a metal rod matched with the sliding rod, and the inverted U-shaped part is manufactured by bending a metal sheet shear plate to manufacture other parts which are commercially available. The prepared parts can be used after being assembled according to the specification and attached drawings. Before use, the patient is in a recumbent state, and the controller key box 1 is positioned at a position from the middle part of the guardrail 4 to the side of the guardrail head, namely, a position near the forearm of the patient in the recumbent state. When a patient wants to sit up, a back lifting key is pressed down, a back bed plate 11 of the electric nursing bed is lifted, as the tail end of the sliding tube 7 is provided with a small hole 8 with the diameter of 2-3mm, a rope 10 in a rope fixed pulley groove is wound on the tail end of the metal sliding rod 5, the tail ends of extending arms 12 of the back bed plate 11 of the nursing bed are pulled by the rope 10 in two pulley grooves of the V-shaped groove fixed pulley 9, when the back bed plate 11 is lifted up, the back bed plate 11 is driven to rotate forwards by the lifting power, the bed plate is driven to generate a reaction force to the extending arms 12 by taking a rotating shaft as the center, namely a backward acting force, and the traction force of the tail end pulling rope 10 drives the sliding tube 7 to drive a controller key box 1 fixed by adhesive to move forwards and in the bed tail direction. Meanwhile, since the end of the rope 10 at the head side of the controller key box 1 is connected with a tension spring/rubber strip 13 having a tensile length of 500mm and a tension of 0.5 Kg; the end of the push button box is fixed on the nursing bed bottom frame 14 below the head side of the guardrail 4, so that the tension spring/rubber strip 13 is stretched to generate elastic potential energy in the process that the controller push button box 1 horizontally moves along the metal sliding rod 5 towards the bed tail direction. When the back bed plate 11 rises to the limit position of about 75 degrees, the back lifting electric push rod is contacted with the inner limit switch, and the automatic power-off operation is stopped. At this point the controller key box 1 has stopped near the patient's forearm on the bed tail side of the guardrail 4. When a patient wants to lie down, the back descending key of the controller key box 1 is pressed, the gear motor of the electric push rod runs reversely, and the back bed board 11 descends, so that in the process that the controller key box 1 horizontally moves along the metal sliding rod 5 towards the tail direction, the tension spring/rubber strip 13 is released by the elastic potential energy generated by being elongated and converted into kinetic energy to pull the rope 10 with the small hole 8 at the head side end of the sliding tube 7 for cable fixation, the sliding tube 7 drives the controller key box 1 to move along the metal sliding rod 5 towards the head side direction, and when the back bed board 11 returns to the horizontal position, the controller key box 1 also returns to the initial position, namely, the position where the key is convenient to operate by the patient by hands. When a patient wants to sit up in another embodiment, when a 'back lifting' key of the controller key box 1 arranged in the middle part of the guardrail 4 is pressed down and positioned at an initial position, the power supply of the micro speed reduction motor 15 connected in parallel is automatically connected on the nut pipe 18, the metal long screw rod 16 connected with the speed reduction motor 15 runs forward while the back bed plate 11 is lifted up, the nut pipe 18 and the controller key box 1 connected with the reverse U-shaped part 3 are driven to move towards the direction of the bed tail, and when the power supply of the electric push rod is connected with the power supply of the micro speed reduction motor 15 in parallel, the patient at the limit position of the angle of 75 degrees when the back bed plate 11 is lifted up, the limit switch arranged in the electric push rod is touched, the electric push rod motor and the micro speed reduction motor 15 are automatically powered off simultaneously, and the controller key box 1 is hung on the nut pipe 18 through the reverse U-shaped part 3, so that the controller key box 1 can automatically move to the position of the guardrail 4 near the position of the bed tail convenient for the patient to operate keys by oneself; when the patient wants to lie down, the back descending key is pressed, the speed reducing motor of the back lifting electric push rod and the miniature speed reducing motor 15 are operated reversely, the push rod is retracted, and when the back bed board descends to the extremely limited 0-degree angle, namely the horizontal position, the controller key box 1 is moved to the initial position of the guardrail from the bed tail side of the guardrail 4, namely the position near the key position is convenient for the patient to operate by himself. When a nursing staff operates, the inverted U-shaped part connected with the controller key box 1 can be taken down, the controller key box is hung on the sliding tube 7 or the nut tube 18 in an outward direction, and when the illness state of a patient is improved and the patient operates by himself, the controller key box 1 is hung in an inward direction. The utility model adopts the lifting of the back bed plate 11 as power, namely a sliding tube-fixed pulley mode or a miniature gear motor 15 as power to drive a long screw rod-nut tube mode, and the controller key box 1 can automatically move along with the change of the patient body position when the patient sits up, lies down or semi-lying down, and the controller key box 1 always tracks the position nearby the hand operation position convenient for the patient.
