Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a balance frame protector for training. Background Art

[0002] The balance training frame is a device used to train balance and lower limb strength for patients with weak balance function and poor lower limb strength. It has the function of assisting patients to stand and walk. Existing balance training frames are mostly divided into fixed and mobile types. When using the fixed training frame, the patient needs to stand or walk between two parallel fixed rods. However, due to the long space between the two fixed rods, the patient cannot be surrounded in all directions, and the patient may fall during training. The mobile training frame is more flexible and the patient can push it independently. However, when the patient falls due to unstable center of gravity due to poor lower limb strength and weak balance function, the mobile training frame is easily displaced along the force of the patient's fall. The stability is poor when the patient falls, and the effect of supporting and protecting the patient is not ideal. Therefore, a training frame is needed that can only be moved when the patient's center of gravity is connected to the training frame. Utility Model Content

[0003] The utility model provides a balance frame protector for training, which has the characteristics that the training frame can only move when the center of gravity of the patient is connected to the training frame, which is beneficial to improving the supporting and protecting effect when the patient falls.

[0004] The top of the two wheels is connected with the driving wheel shaft through the two wheels, and the driving wheel shaft through the two wheels is connected with the driving wheel shaft through the two wheels.

[0005] Wherein, a connecting seat is provided on one side of the supporting frame, and the baffle is rotatably connected to the connecting seat.

[0006] Wherein, a limit knob and a fixed block are provided on one side of the support frame, the limit knob is rotatably connected to the support frame, the fixed block is fixedly connected to the support frame, and the fixed block is located on one side of the bottom of the limit knob.

[0007] Wherein, the telescopic support rod 1 and the telescopic support rod 2 are both provided with a plurality of limiting holes 1, and the inner side of the limiting hole 1 is movably connected with a protrusion 1.

[0008] Among them, a plurality of second limiting holes are opened on the push rod, and a second protrusion is movably connected to the inner side of the second limiting hole, and the spacing between the plurality of second limiting holes is the same as the spacing between the plurality of first limiting holes.

[0009] Wherein, the push rod passes through the support frame, and the armrest is located above the support frame.

[0010] The beneficial effect of the utility model is that when the patient leans on the armrest and presses it down, the patient's center of gravity is located on the armrest, and the elastic limit pad releases the limit on the moving wheel through the linkage between the push rod, the second rack, the first rack and the movable rod. When the patient's center of gravity shifts and separates from the armrest, the spring will drive the elastic limit pad to reset downward to limit the moving wheel, avoiding the protection frame from moving when the patient's center of gravity is separated from the armrest. The training frame can only move when the patient's center of gravity is connected to the training frame, which is beneficial to improving the support and protection effect when the patient falls.

[0011] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the spring 222 is fixedly connected to the inner top of the fixed cover 22. A movable rod 23 is slidably connected to the inner side of the fixed cover 22. The movable rod 23 corresponds to the position of the moving wheel 21, and the fixed cover 22 is slidably connected to the inner side of the through slot 221. A pressing plate 231 is provided at the bottom of the movable rod 23. The pressing plate 231 is fixedly connected to the movable rod 23. An elastic limiting pad 232 is provided at the bottom of the pressing plate 231. When the movable rod 23 moves downward, the elastic limiting pad 232 will be squeezed on the top of the moving wheel 21. 2 and the moving wheel 21 is relatively large, the moving wheel 21 can be limited by squeezing the elastic limiting pad 232, so that the moving wheel 21 cannot continue to rotate. Since the friction between the moving wheel 21 itself and the ground is relatively large, when the moving wheel 21 cannot rotate, the purpose of limiting the telescopic support rod 2 can be achieved. The outer side of the movable rod 23 is provided with a push plate 233 connected to the spring 222, and the push plate 233 is fixedly connected to the movable rod 23. When the movable rod 23 moves upward, the spring 222 will be compressed upward.

The tops of the two push rods 4 are connected by an armrest 44, and the two ends of the armrest 44 are fixedly connected to the tops of the two push rods 4 respectively. When the patient holds on the armrest 44 and presses it down, the center of gravity of the patient is located on the armrest 44, and the push rod 4, The linkage between the rack 2 43, the rack 1 234 and the movable rod 23 releases the limit of the movable wheel 21 by the elastic limit pad 232. When the patient's center of gravity deviates and separates from the armrest 44, the spring 222 will drive the elastic limit pad 232 to reset downward to limit the movable wheel 21, so as to prevent the protection frame from moving when the patient's center of gravity is separated from the armrest 44. The training frame can only move when the patient's center of gravity is connected to the training frame, which is beneficial to improve the support and protection effect when the patient falls.

[0020] A connecting seat 11 is provided on one side of the support frame 1, and a baffle 12 is rotatably connected to the connecting seat 11; through the connection between the connecting seat 11 and the baffle 12, the baffle 12 can be horizontally rotated on one side of the support frame 1, and the patient can be given way or limited by the rotation of the baffle 12.

[0022] A plurality of limiting holes 31 are provided on the telescopic support rod 1 2 and the telescopic support rod 2 3, and a protrusion 32 is movably connected to the inner side of the limiting hole 31; the height of the telescopic support rod 1 2 or the telescopic support rod 2 3 can be adjusted through the protrusion 32 and the limiting hole 31, so that the height of the training frame is maintained at a comfortable state for the patient.

[0024] The push rod 4 passes through the support frame 1, and the armrest 44 is located above the support frame 1; when the patient leans on the armrest 44 and presses down, the armrest 44 will move downward to contact the top of the support frame 1, so that the patient's center of gravity is on the armrest 44, the support frame 1 and the telescopic support rod 2, which is conducive to ensuring that the training frame can only move when the patient's center of gravity is connected to it.

[0025] The working principle and use process of the utility model are as follows: when in use, the height of the telescopic support rod 1 and the telescopic support rod 2 are first adjusted through the limiting hole 1 31 and the protrusion 1 32 to keep the height of the support frame 1 at a comfortable state for the patient, and then the baffle 12 is rotated outward so that the patient can enter the inner side of the support frame 1, and then the baffle 12 is rotated to reset, and the baffle 12 is limited by the limiting knob 13 to surround the patient inside. When the patient leans on the armrest 44 and presses it down, the patient's center of gravity is at the right position. On the armrest 44, the support frame 1 and the telescopic support rod 2, at the same time, the downward movement of the armrest 44 will drive the elastic limiting pad 232 to release the limit on the moving wheel 21, and the patient can push the training frame for walking training. When the patient's center of gravity shifts and separates from the armrest 44, the spring 222 will drive the elastic limiting pad 232 to reset downward to limit the moving wheel 21, avoiding the movement of the protection frame when the patient's center of gravity is separated from the armrest 44. The training frame can only move when the patient's center of gravity is connected to the training frame.
