Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 6 and give, base 1 including the fore-and-aft direction, but base 1 top is equipped with a luffing motion's bed board 2, base 1 left end is equipped with horizontally layer board 3, be equipped with two backup pads 4 that arrange and can the horizontal slip along the fore-and-aft direction on the layer board 3, be equipped with between two backup pads 4 and reciprocate and control pivoted eccentric wheel 5, keyway 6 has been seted up to eccentric position on the eccentric wheel 5, be equipped with spline 7 in the keyway 6, both ends are equipped with axial pivot 8 around the spline 7 respectively, all set up a plurality ofly on two backup pads 4 with the pivot 8 with the axial and along the round hole 9 that the direction was arranged from top to bottom, slide rail 10 that link up around all seting up between per two relative round holes 9 from top to bottom, its round hole 9 that corresponds the side is stretched out respectively to the free end of two pivot 8, the equal sliding.
In order to enable the bed board 2 to be horizontally placed, the front side and the rear side of the base 1 are respectively provided with a bed leg 12 positioned at the right end of the base, the upper ends of the two bed legs 12 are respectively provided with a flat plate 14 positioned at the left side of the two bed legs, the lower surface of the bed board 2 is in surface contact with the flat plate 14, the front side and the rear side of the base 1 are respectively provided with a support 13 positioned at the left side of the base and in an inverted U shape, and the left end of.
In order to conveniently support the bed board 2, the right side of the base 1 is hinged with an electric telescopic rod 15, the electric telescopic rod 15 inclines leftwards, and the upper end of the electric telescopic rod is hinged with the bottom surface of the bed board 2.
In order to facilitate the patient to stand, the left side and the right side of the bed plate 2 are respectively provided with a binding belt 16 in the front-back direction, and the binding belt 16 is provided with a connecting buckle 17.
In order to make eccentric wheel 5 can the adjusting position in the left and right directions, layer board 3 on set up the left and right directions and be the slide 18 of type shape, sliding connection has slider 19 in slide 18, both sides are equipped with relative gyro wheel 20 around the slider 19 respectively, slide 18 bottom is opened has a plurality of first spacing holes 21 along left and right directions equipartition, the slider 19 left and right sides is seted up respectively about link up and can be with the spacing hole 22 of the second that first spacing hole 21 corresponds, all be equipped with the stopper 23 that can insert in the spacing hole 21 of second in the spacing hole 22, two backup pad 4 bottoms and slider 19 upper surface fixed connection.
In order to enable the eccentric wheel 5 to rotate more smoothly, the inner sides of the two pedals 11 are respectively provided with a bearing 24 with the outer surface being parallel to the outer edge surface of the pedal 11, the outer edge surface of the bearing 24 can be in close contact with the inner surface of the round hole 9, a limiting sliding groove 25 which is in the front-back direction and has an inward opening is formed in the pedal 11, a limiting sliding block 26 is arranged in the limiting sliding groove 25, and the limiting sliding block 26 is fixedly connected with the outer surface of the rotating shaft 8 on the corresponding side.
When the utility model is used, the position of the eccentric wheel 5 and the inclination angle of the bed plate 2 can be adjusted according to different requirements of the exercise intensity of patients;
at the initial stage of training, a patient lies on the bed board 2, a caregiver pulls up all the limiting blocks 23 to separate from the first limiting holes 21, pushes the sliding blocks 19 to slide rightwards to the position near the left end of the bed board 2, then pulls out the two pedals 11 outwards, the limiting sliding blocks 26 slide outwards along the limiting sliding grooves 25 to expose the rotating shafts 8, pulls the rotating shafts 8 to move upwards along the sliding rails 10 to lift the eccentric wheels 5 to be positioned at the upper parts of the supporting plates 4 and close to the positions of the feet of the patient, then pushes the pedals 11 inwards, the limiting sliding blocks 26 slide inwards along the limiting sliding grooves 25 to enable the bearings 24 on the pedals 11 to be inserted into the round holes 9, at the moment, the outer edge surfaces of the bearings 24 are in close contact with the inner surfaces of the round holes 9, the patient can step on the pedals 11 with both feet in a lying posture to perform pedaling motion, the pedals 11 drive the rotating shafts 8 to rotate, when the eccentric wheel 5 rotates, different forces are needed for rotating at different angles, so that the purpose of exercise is achieved;
in the middle period of training, a patient sits on the left side of the bed plate 2, the nursing staff adjusts the position of the slide block 19 and the height of the eccentric wheel 5 to a proper position according to the operation mode, at the moment, the patient can step on the pedals 11 with feet in a sitting posture to do pedal motion, and the pedals drive the rotating shaft 8 and the eccentric wheel 5 to rotate, so that the purpose of exercise is achieved;
training later stage, at first loosen connection buckle 17 on the bandage 16, patient lies on bed board 2, then the caregiver fixes patient on bed board 2 with bandage 16, buckle 17 is connected in the straining, start electric telescopic handle 15 after that, electric telescopic handle 15 stretches out along the upper left direction of slant this moment, it risees to drive the pin joint rotation of bed board 2 around the support 13 left end, then the caregiver adjusts the position of slider 19 and eccentric wheel 5 to suitable position according to above-mentioned operation mode, patient can be under the assistance of bed board 2 this moment, step on pedal 11 with both feet and carry out pedal motion, after the exercise, restore to the throne electric telescopic handle 15, electric telescopic handle 15 retracts along slant lower right direction this moment, it reduces to drive the pin joint rotation of bed board 2 around the support 13 left end, finally restore to the throne.
The electric telescopic rod 15 of the present invention is prior art, and its structure is not described in detail here.
Compared with the prior art, the beneficial effects of the utility model are that: set up electric telescopic handle on the base, can control the bed board and go up and down, can assist patient to stand, set up eccentric wheel height and slider position adjustable, can satisfy patient's different demands of taking exercise the posture in prone position, position of sitting, the standing posture, patient can set up the eccentric wheel structure according to the recovery condition free choice exercise posture of self, can suitably improve and temper intensity, this simple structure, think about novel, the usability is strong.
