[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0018] like Figure 1-Figure 5 As shown, a safety anti-fall frame for osteoporosis rehabilitation of the present invention comprises a U-shaped bracket 1, wherein the upper four corners of the U-shaped bracket 1 are fixedly connected with a support rod 2, and the inside of the support rod 2 is slidably connected with a telescopic rod 3, a semicircular fixing plate 4 is provided on the outer side of the U-shaped bracket 1, and the upper four corners of the semicircular fixing plate 4 are fixedly connected with a support rod 41, and the other end of the support rod 41 is fixedly connected with a first fixing sleeve 42, and the first fixing sleeve 42 is sleeved on the support rod 2, and the lower end of the semicircular fixing plate 4 is provided with an air bag 5, and one side of the air bag 5 is provided with an inflation port 51, and a first fixing rod 6 is fixedly connected between the two telescopic rods 3 near the opening of the U-shaped bracket 1, and a first stretching plate 7 and a second stretching plate 8 are rotatably connected to the first fixing rod 6 through a rotating shaft, and the other ends of the first stretching plate 7 and the second stretching plate 8 are rotatably connected with a sliding rod 9 through a rotating shaft, and both ends of the sliding rod 9 are slidably connected to the telescopic rod 3 at both ends through sliders 91; The telescopic rods 3 at both ends of the sliding rod 9 are fixedly connected to a fixed groove 10 on one side away from the sliding rod 9. The fixed grooves 10 are located obliquely above the slider 91. A first return spring 11 is provided inside the fixed groove 10. The first return spring 11 is fixedly connected to a trapezoidal block 12 at one end close to the sliding rod 9. The middle part of the end of the trapezoidal block 12 close to the fixed groove 10 is fixedly connected to a connecting rod 121. The other end of the connecting rod 121 is fixedly connected to a spherical block 122. The telescopic rods 3 without the first fixing rod 6 are fixedly connected with the second fixing rod 13, and the telescopic rods 3 with the first fixing rod 6 and the telescopic rods 3 with the second fixing rod 13 are fixedly connected via an armrest 14, and two baffles 15 are provided below the armrest 14, and both ends of the baffles 15 are fixedly connected to the telescopic rods 3 at both ends; The U-shaped bracket 1 is fixedly connected to an L-shaped fixing plate 16 at one end close to the second fixing rod 13, and a rest stool 18 is slidably connected to the middle part of the L-shaped fixing plate 16 through a T-block 17. A support column 19 passing through the L-shaped fixing plate 16 is fixedly connected to the middle part of the lower end of the rest stool 18, and a fixing block 20 is fixedly connected to the other end of the support column 19. A second return spring 21 is sleeved on the support column 19, and the second return spring 21 is located between the rest stool 18 and the L-shaped fixing plate 16. A third fixing rod 22 is fixedly connected to both sides of one side of the upper end of the L-shaped fixing plate 16 close to the telescopic rod 3, and the other ends of the third fixing rod 22 are fixedly connected to a second fixing sleeve 221, and the second fixing sleeve 221 is sleeved on the nearest telescopic rod 3.
[0019] Specifically, there is a long distance between the end of the semicircular fixing plate 4 away from the resting stool 18 and the U-shaped bracket 1, so as to facilitate the patient to walk.
[0020] Specifically, the first stretching plate 7 and the second stretching plate 8 are arranged at a cross position in the middle, and the first stretching plate 7 and the second stretching plate 8 are rotatably connected in the middle through a rotating shaft, so as to drive the sliding rod 9 to move along the sliding groove 31 .
[0021] Specifically, the first fixed rod 6 is provided with a first limiting groove 61 corresponding to the first stretching plate 7 and the second stretching plate 8, and the sliding rod 9 is provided with a second limiting groove 92 corresponding to the first stretching plate 7 and the second stretching plate 8. The upper ends of the first stretching plate 7 and the second stretching plate 8 are located in the first limiting groove 61, and the lower ends of the first stretching plate 7 and the second stretching plate 8 are located in the second limiting groove 92. This facilitates the limiting of the first stretching plate 7 and the second stretching plate 8.
[0022] Specifically, the telescopic rods 3 at both ends of the sliding rod 9 are provided with sliding grooves 31 corresponding to the sliders 91, and the sliders 91 are all located in the sliding grooves 31. The sliders 91 can slide smoothly on the telescopic rod 3, and at the same time drive the sliding rod 9 to slide along the direction of the sliding grooves 31.
[0023] Specifically, the trapezoidal block 12 is a right-angled trapezoidal structure, the inclined surface of the trapezoidal block 12 faces upward, the inclined portion of the trapezoidal block 12 is located in the slide groove 31, and the trapezoidal block 12 is located at the upper end of the slider 91. When the slider 91 slides from the upper part of the trapezoidal block 12 to the trapezoidal block 12, the trapezoidal block 12 can be smoothly squeezed to compress the first return spring 11 until the slider 91 is completely located at the lower end of the trapezoidal block 12, and the first return spring 11 restores its elasticity, so that the trapezoidal block 12 returns to its original position, so that the slider 91 is stuck at the lower end of the trapezoidal block 12, and the slider 91 and the sliding rod 9 are fixed.
[0024] Specifically, the L-shaped fixing plate 16 is provided with a sliding groove 161 corresponding to the T-shaped block 17, and the T-shaped block 17 is located in the sliding groove 161. When the patient sits on the resting stool 18, the second return spring 21 is compressed, so that the T-shaped block 17 can slide smoothly along the sliding groove 161, so that the resting stool 18 descends, and the resting stool 18 descends while driving the support column 19 and the fixing block 20 to descend until the fixing block 20 is located on the ground surface, so that the resting stool 18 can be stabilized, so that the person can sit more steadily.
[0025] Specifically, the four corners of the lower end of the U-shaped bracket 1 are fixedly connected with universal wheels 23, which is convenient for patients to use and move.
[0026] When in use, first pull the two ball blocks 122 and lift the sliding rod 9 upwards. At this time, the first stretching plate 7 and the second stretching plate 8 will move to both sides along the first limiting groove 61 and the second limiting groove 92 until the patient can enter the interior of the U-shaped bracket 1. Then, move the sliding rod 9 downwards until the sliding rod 9 is stuck with the lower end of the trapezoidal block 12, so as to fix the slider 91 and the sliding rod 9. Then, the height of the armrest 14 is adjusted to a suitable position by the telescopic rod 3, and the patient can hold the armrest 14 to do some rehabilitation exercises, such as slow walking, squatting exercises, and stepping on the spot. When walking slowly, the universal wheel 23 can be driven to rotate, so that the anti-fall frame and the patient move at the same time, which is convenient for rehabilitation training; If the patient is about to fall, the first fixed rod 6, the first stretching plate 7, the second stretching plate 8, the sliding rod 9, the baffle 15 and the second fixed rod 13 can all play a protective role for the patient. At this time, the airbag 5 will contact the ground, thereby preventing the patient from falling. When the patient is tired during rehabilitation training, he can sit on the rest stool 18 to rest. When the patient sits on the rest stool 18, the second return spring 21 is compressed, so that the T-block 17 can slide smoothly along the sliding groove 161, so that the rest stool 18 descends. When the rest stool 18 descends, it can drive the support column 19 and the fixed block 20 to descend until the fixed block 20 is located on the ground surface, which can make the rest stool 18 stable and make the patient sit more steadily. When the patient stands up, the second return spring 21 restores its elasticity, so that the rest stool 18, the support column 19 and the fixed block 20 return to their original positions, and then the patient can continue to do rehabilitation training.
