Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, box body 1 including the left and right directions, be equipped with two but back-and-forth movement and the switching-over post 2 of falling L shape in the box body 1, two switching-over post 2 openings back to the back and move opposite direction, polygonal groove 3 has been seted up to switching-over post 2 outer end, it has left right axial connecting box 4 to rotate on the switching-over post 2, coaxial sliding connection in connecting box 4 outer end has removal box 5, it has polygon post 6 that can insert in polygonal groove 3 to move on the box 5 coaxially, be equipped with the ratchet 7 that is located the connecting box 4 outside on the switching-over post 2, it has the pawl that can cooperate with ratchet 7 to move the articulated in the box 5, it is connected with the slider 9 that is located switching-over post 2 the place ahead to move box 5 through stretching strap 8, slider 9 and box body 1 sliding connection, slider 9 upper end runs through box body 1 and articulates there is the backup pad 10 that has L shape.

In order to enable the reversing column 2 to move back and forth, a square block is arranged at the lower end of the reversing column 2 and is in sliding connection with the box body 1.

In order to make the moving directions of the two reversing columns 2 opposite, the box body 1 is rotatably connected with a swing rod 11 in the left and right directions, the left and right sides of the swing rod 11 are respectively provided with a vertical through kidney-shaped groove, and the reversing columns 2 are inserted into the kidney-shaped grooves on the corresponding sides.

In order to facilitate the control to move the box 5, box body 1 about both ends seted up respectively about link up and the fore-and-aft direction groove of stepping down, axial and axial cross-section are the control post 12 of T shape about being equipped with in 6 outer ends of polygonal post, the groove of stepping down is stretched out to control post 12 outer end, set up three annular 13 that distributes along the left and right directions on the control post 12, sliding connection has dog 14 that can insert in the annular 13 on the side wall under the groove of stepping down, dog 14 lower extreme is connected with box body 1 through the pressure spring.

In order to facilitate the resetting of the connecting box 4 and the pawl, a coil spring 15 is arranged between the connecting box 4 and the reversing column 2, and an elastic sheet is arranged between the upper end of the pawl and the moving box 5.

In order to ensure the stability of the supporting plate 10, the upper ends of the sliding block 9 and the box body 1 are respectively provided with a supporting block, the lower end of the supporting plate 10 can be contacted with the supporting block, and the supporting plate 10 is provided with a fixing belt.

When the utility model is used, the initial state is that the two stop dogs 14 are respectively inserted into the annular groove 13 at the innermost side, the pawl is not inserted into the ratchet wheel 7 and is positioned at the outer side of the ratchet wheel 7, because the upper end of the elastic sheet is connected with the moving box 5, and the lower end of the elastic sheet is connected with the pawl, the pawl keeps a certain inclination angle even if not inserted into the ratchet wheel 7, thereby being convenient to be inserted into the ratchet wheel 7, the polygonal column 6 is not inserted into the polygonal groove 3, and the coil spring 15 is not stressed;

adjusting according to the conditions of the two legs of the patient, if the left limb of the patient is a diseased limb and the right limb of the patient is a healthy limb, the two legs of the patient are respectively placed on the supporting plate 10 and fixed and limited by using the fixing belt, the right control column 12 is pushed forwards, the right reversing column 2 synchronously moves forwards and gradually approaches the sliding block 9, the left reversing column 2 moves backwards under the action of the oscillating bar 11, the drawstring 8 drives the left moving box 5 to rotate, and the moving box 5 drives the connecting box 4 to rotate and enables the coil spring 15 to shrink under force;

when the control column 12 on the right side moves to the limit position on the front side, the control column 12 on the right side stops being pushed forwards, the control column 12 on the right side is pushed leftwards, the stop block 14 is inserted into the annular groove 13 on the outermost side, at the moment, the pawl on the right side is positioned on the inner side of the ratchet 7 and is not connected with the ratchet 7, the polygonal column 6 on the right side is inserted into the polygonal groove 3, the movable box 5 and the connecting box 4 cannot rotate, and the length of the pull belt 8 on the right side, which is not wound on the movable box 5, is determined;

the left control column 12 is pushed rightwards, the left stop block 14 is inserted into the middle annular groove 13, at the moment, the pawl on the left side is inserted into the ratchet wheel 7, the polygonal column 6 is not inserted into the polygonal groove 3, the movable box 5 can rotate in a single direction, the left control column 12 is rotated, the control column 12 drives the connecting box 4 to rotate and the left pull belt 8 is gradually wound on the movable box 5, the slide block 9 drives the support plate 10 to move backwards and drive the knee joint of the affected limb of the patient to bend, and due to the action of the ratchet wheel 7 and the pawl, when the control column 12 is not rotated by the slide block 9, the pull belt 8 cannot drive the movable box 5 to rotate;

when the knee joint of the affected limb of the patient bends to reach the maximum angle which can be borne by the body, the left control column 12 stops rotating, the left control column 12 is pushed rightwards, the stop block 14 is inserted into the leftmost annular groove 13, at the moment, the pawl is separated from the ratchet wheel 7, the polygonal column 6 is inserted into the polygonal groove 3, the coil spring 15 is in a stressed contraction state, the length of the pull belt 8 which is not wound on the movable box 5 is limited, the maximum distance between the slide block 9 and the movable box 5 is limited, and at the moment, the exercise can be started;

the healthy limb on the right side of the patient is bent and drives the slide block 9 on the right side to move backwards through the fixing belt and the supporting plate 10, the slide block 9 pushes the reversing column 2 to move backwards, the swing rod 11 swings and pushes the moving box 5 on the left side to move forwards, the slide block 9 on the left side moves forwards under the action of the gravity of the affected limb of the patient, and the affected limb of the patient is gradually straightened;

when patient's healthy limb is crooked to extreme position, patient's affected limb is for straightening the state and left stretching strap 8 is in the relaxed state, but because remove box 5 unable rotation this moment, so stretching strap 8 can't twine under coil spring 15's effect on removing box 5, when healthy limb on patient right side straightens, slider 9 on right side drives switching-over post 2 forward movement through stretching strap 8, left switching-over post 2 is synchronous rearward movement, left stretching strap 8 is straightened gradually and pulls left slider 9 rearward movement, patient's affected limb joint begins to be crooked, so reciprocal realization is taken exercise the bending of both legs, and the crooked angle of affected limb is different with healthy limb.

The upper ends of the sliding block 9 and the box body 1 are respectively provided with a supporting block, so that the supporting plate 10 keeps the rear end in an upward inclined state, the joint of a patient can be conveniently bent, and the leg part can be stably supported.

The utility model has simple structure, convenient operation, novel conception and strong practicability, and the reversing column, the connecting box, the drawstring, the ratchet wheel, the pawl, the polygonal groove, the polygonal column, the control column, the ring groove and the stop block are arranged, and the stop block is inserted into different ring grooves, so that the connection between the pawl and the ratchet wheel, and the connection between the polygonal column and the polygonal groove are realized, and the length of the drawstring between the slide block and the moving box is further controlled, so that the affected limb of a patient can be bent at different angles, and the use requirements of different patients are met.
