Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an exercise auxiliary device. Background Art

[0002] Myasthenia gravis is a chronic disease that requires long-term treatment for recovery. There are three general rehabilitation exercises for myasthenia gravis: walking training, sitting training, and active exercise training for healthy limbs. Walking training mainly stimulates muscles by taking steps and going up and down stairs to increase muscle strength.

[0003] When patients are doing stair training, the height of the steps is generally fixed, mostly 10-15cm. For patients with muscle weakness, going up and down high stairs is extremely difficult, which increases the psychological pressure on patients and inevitably causes inferiority complex. Although some hospitals have special training stairs, the height between every two adjacent steps is also fixed, and the height between multiple steps gradually increases from bottom to top. Patients often find it easier to go up the first step, but it will be more difficult to go up further. When going down the stairs, they use more upper limb strength for support, which may lead to postural compensation, affecting the patient's leg and waist muscle training, and even causing adverse effects on the bones of the limbs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a training auxiliary device, which effectively solves the problem that the height of the existing training steps cannot be adjusted according to the patient's muscle strength.

[0005] The technical solution is as follows: the utility model comprises a base, a plurality of slide grooves are provided on the base in the front-to-back direction and distributed in the left-to-right direction, a T-shaped step plate is slidably connected in the slide groove, the upper end surfaces of the plurality of step plates gradually rise from right to left, the plurality of step plates are respectively provided with left-to-right through grooves, a cavity connected with the through groove is provided on the base, a slide plate which can move left-to-right is provided in the cavity, a plurality of guide grooves corresponding to the step plates are provided on the slide plate, the heights of the plurality of guide grooves increase successively from right to left, the guide groove comprises a plurality of inclined grooves which are lower on the left and higher on the right, every two adjacent inclined grooves are connected end to end via a horizontal groove, the lengths of the plurality of horizontal grooves are equal, a front-to-back axial fixed rod is fixed in the through groove, and the fixed rod passes through the corresponding guide groove.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The utility model has an ingenious structure and is easy to use. A plurality of guide grooves are designed, and the guide grooves include an oblique groove and a horizontal groove. The lengths of the plurality of oblique grooves on the same guide groove are equal, and the height difference between every two adjacent oblique grooves on the left and right is equal, so that when the plurality of step plates are raised, the height difference between every two adjacent step plates is equal, which is convenient for adjusting the height of the steps according to the leg and waist strength of the patient, and is also conducive to the patient to perform up and down training on the steps with the uniform height difference, avoiding posture compensation, and also increasing the patient's confidence and sense of accomplishment, enhancing the patient's interest in training, and improving the training effect of leg and waist strength;

[0008] The height of multiple step boards can be adjusted by simply turning the hand wheel. It is simple to operate, suitable for patients with different leg and waist strength, and easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 6 It is given, including a base 1, on which are provided a plurality of slide grooves in the front-to-back direction and distributed along the left-to-right direction, a T-shaped step plate 2 is slidably connected in the slide groove, the upper end surfaces of the plurality of step plates 2 gradually rise from right to left, and the plurality of step plates 2 are respectively provided with left-to-right through grooves, a cavity 4 connected to the through groove 3 is provided on the base 1, a slide plate 5 movable left-to-right is provided in the cavity 4, a plurality of guide grooves corresponding to the step plates 2 are provided on the slide plate 5, and the heights of the plurality of guide grooves increase successively from right to left, the guide grooves include a plurality of inclined grooves 6 which are lower on the left and higher on the right, every two adjacent inclined grooves 6 are connected end to end through a horizontal groove 7, the lengths of the plurality of horizontal grooves 7 are equal, a front-to-back axial fixed rod 8 is fixed in the through groove 3, and the fixed rod 8 passes through the corresponding guide grooves.

[0017] In order to enable the slide plate 5 to move in the cavity 4 , the slide plate 5 is slidably connected to the cavity 4 , and a left and right axial screw rod 9 is rotatably connected to the base 1 , and the slide plate 5 is threadedly connected to the screw rod 9 .

[0018] In order to facilitate the operation of the screw rod 9 to rotate, the left end of the screw rod 9 passes through the base 1 and is fixed with a hand wheel 10.

[0019] In order to improve the training effect, the lengths of the multiple inclined grooves 6 on the same guide groove are equal, and the height differences between every two adjacent inclined grooves 6 are equal.

[0020] In order to protect the patient, the base 1 is fixed with H-shaped rods 11 on the front and rear sides respectively, and the left and right sides of the H-shaped rod 11 are respectively provided with vertical grooves with openings facing upwards. Every two left and right opposite vertical grooves are slidably connected with an inverted U-shaped armrest 12, and the left ends of the two armrests 12 are connected by a support rod.

[0021] In order to ensure that the handrail 12 meets the patient's usage requirements when the step plate 2 is raised, the left and right sides of the H-shaped rod 11 are respectively threadedly connected with bolt knobs 13, and the inner ends of the bolt knobs 13 can contact the outer surface of the handrail 12.

[0022] When the utility model is in use, the fixed rod 8 is arranged at the lowest side of the guide groove, the left end of the slide plate 5 does not contact the side wall of the cavity 4, and the rightmost step plate 2 is in the lowest initial state. For example, the distance between the upper end surface of the rightmost step plate 2 and the upper end surface of the base 1 is "1cm", and at this time, the height difference between the upper end surfaces of every two adjacent step plates 2 is "1cm";

[0023] The patient stands on the base 1, holds the handrails 12 on both sides, and alternately goes up multiple step boards 2 with the left foot and the right foot from right to left. When the patient walks from the right end to the left end, the patient turns around and then goes down multiple step boards 2 from left to right in sequence. When the patient's leg and waist core strength increases to the point where he can go up and down the step boards 2 without holding the handrails 12, the patient independently and actively goes up and down multiple step boards 2 from right to left and from left to right in sequence, so as to train the patient's leg and waist muscles.

[0024] After the core strength of the patient's legs and waist increases, when it is necessary to increase the height difference of adjacent step boards 2 to improve the training intensity, the hand wheel 10 is turned, and the hand wheel 10 drives the screw rod 9 to rotate. Since the slide plate 5 is slidably connected to the cavity 4, the slide plate 5 moves to the left along the screw rod 9, and the inclined groove 6 pushes the fixed rod 8 to drive the corresponding step board 2 to move upward. When the fixed rod 8 is located in the first horizontal groove 7 from bottom to top, the hand wheel 10 is stopped. Due to the self-locking characteristics of the spiral transmission, the height of the multiple step boards 2 always maintains the current state. At this time, the height difference between the upper end surfaces of every two adjacent step boards 2 is equal (for example, 2 cm) and is greater than the height difference in the initial state. The patient goes up and down multiple step boards 2 from right to left and from left to right in turn to train the patient's leg and waist muscles;

[0025] Similarly, according to the patient's muscle strength increase, the hand wheel 10 is turned to adjust the height of the multiple step boards 2 to increase the height difference between adjacent step boards 2, increase the training intensity, and improve the training effect of leg and waist muscle strength.
