Technical Field
[0001] This utility model relates to the field of walking aids for safe rehabilitation training, and in particular to walking aids for safe rehabilitation training. Background Technology
[0002] A walking aid, also known as a lower limb orthosis, is a walking support tool used by elderly people with mobility difficulties, certain injured or paralyzed patients, and people with disabilities to help themselves walk or exercise their limb strength. People can walk slowly and easily while holding onto it.
[0003] The inventors discovered during daily use of the walking aid that, because the walking aid's surface lacks a limiting device, patients cannot accurately observe the distance they move. This can lead to patients moving too far, causing them to fall, worsening their condition, and hindering their recovery. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safe rehabilitation training walking aid.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safe rehabilitation training walking aid, comprising a walking aid, wherein the bottom of the walking aid is provided with universal wheels, the bottom of the walking aid is provided with an anti-slip device, the side of the walking aid is provided with a limiting device, the limiting device includes a rectangular frame fixedly connected to the side of the walking aid, a rotating rod is rotatably connected inside the rectangular frame, a limiting band is wound around the surface of the rotating rod, one end of the limiting band is fixedly connected with a buckle, and a clip frame is fixedly connected to the side of the walking aid.
[0006] The aforementioned components achieve the following effect: under the action of the frame and buckle, the other end of the limiting strap is fixed, thereby limiting the movement distance of the walker and preventing excessive movement. When the walker needs to be used, move it in front of the patient, have the patient hold the handles on both sides of the top of the walker with both hands, and slightly lift the walker so that the rear end of the walker separates from the ground, allowing the casters to rotate and move the walker. After moving to a suitable distance, bring the rear end of the walker into contact with the ground to fix it in place. Then, the patient moves forward to follow the walker, repeating the above steps to enable the patient to perform rehabilitation training.
[0007] Preferably, a locking rod is inserted into one end of the rotating rod, and a circular groove is formed on the surface of the rectangular frame, into which the locking rod is inserted.
[0008] The effect achieved by the above components is that, under the action of the locking rod, the limiting band can be fixed after extending to a suitable length, thereby achieving the function of adjusting the length of the limiting band.
[0009] Preferably, a first spring is sleeved on the surface of the clamping rod, and the two ends of the first spring are respectively fixedly connected to one end of the rotating rod and one end of the clamping rod.
[0010] The effect achieved by the above components is that, under the action of the first spring, the locking lever is inserted into the inside of the circular groove in a self-locking manner.
[0011] Preferably, a pad, which is a rubber plate, is fixedly connected to the side of the limiting band.
[0012] The aforementioned components achieve the following effects: The pad prevents the restraint strap from constricting the patient's legs. When the patient needs to perform rehabilitation training, the walker is moved in front of the patient for them to grasp. The lever is pulled upwards to separate from the circular groove, and the restraint strap is pulled out from inside the rectangular frame. Once pulled out to a suitable length, since the restraint strap does not need to be precise to the millimeter, it can be restrained by the lever's insertion into the circular groove. Under the action of the first spring, the lever self-locks into the circular groove, and the other end of the restraint strap is fixed to the frame with a buckle. This prevents the patient from falling due to moving the walker a large distance, thus achieving the restraint function.
[0013] Preferably, the anti-slip device includes a retaining ring fixedly connected to the surface of the walker, a sleeve rod is sleeved on the bottom of the walker, an annular groove is formed on the inner wall of the sleeve rod, and an anti-slip block is fixedly connected to one end of the sleeve rod.
[0014] The effect achieved by the above components is that, under the action of the retaining ring and the ring groove, the sleeve can be locked at the bottom of the walker, preventing the walker from slipping and causing the walker to move too far forward, which could lead to the patient falling.
[0015] Preferably, a magnetic block is fixedly connected to the bottom of the walking aid, and a magnetic plate is fixedly connected to the inner wall of the sleeve.
[0016] The effect achieved by the above components is that, under the magnetic attraction between the magnetic block and the magnetic plate, the sleeve can be fixed to the bottom of the walker.
[0017] Preferably, a locking rod is inserted into the surface of the sleeve rod, and the locking rod is inserted into the interior of the walking aid.
[0018] The effect achieved by the above components is that, under the action of the locking rod, the sleeve can be firmly fixed to the bottom of the walker, preventing the walker from slipping.
[0019] Preferably, a second spring is sleeved on the surface of the locking rod, and the two ends of the second spring are respectively fixedly connected to one end of the locking rod on the surface of the sleeve.
[0020] The aforementioned components achieve the following effects: Under the action of the second spring, the anti-slip block can be quickly replaced after wear. When the walker is needed, the sleeve is fitted onto the bottom of the walker. Under the action of the retaining ring and the ring groove, the sleeve can be locked into the bottom of the walker, preventing the walker from sliding and causing the walker to move too far forward, resulting in the patient falling. During the fitting process, the magnetic attraction between the magnetic block and the magnetic plate allows the sleeve to be fixed to the bottom of the walker. When the magnetic plate and the magnetic block attract each other, under the action of the second spring, the locking rod is inserted into the interior of the walker, thereby achieving a fixing effect and preventing the walker from sliding, thus achieving an anti-slip effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a limiting device, when the patient needs to perform rehabilitation training, the walker is moved in front of the patient so that the patient can grasp it, the locking rod is pulled upward to separate it from the circular groove, and the limiting band is pulled out from the inside of the rectangular frame. When it is pulled out to a suitable length, since the limiting band does not need to be accurate to millimeters, it can be limited by the structure of the locking rod inserting into the circular groove. Under the action of the first spring, the locking rod is self-locking and inserted into the inside of the circular groove. The other end of the limiting band is fixed to the frame by a buckle, thereby preventing the patient from falling due to moving the walker a large distance. This achieves the limiting function and solves the problem that the patient is prone to falling when moving the walker a large distance. Attached Figure Description

[0027] Example 1, as Figure 1-3As shown, the safe rehabilitation training walking aid 1 includes a walking aid 1, with casters 4 at the bottom and an anti-slip device 3 at the bottom. A limit device 2 is located on the side of the walking aid 1. When the walking aid 1 is needed, it is moved to the front of the patient, who then holds the handles on both sides of the top of the walking aid 1 and slightly lifts it, causing the rear end of the walking aid 1 to separate from the ground. This allows the casters 4 to rotate, moving the walking aid 1. After moving it to a suitable distance, the rear end of the walking aid 1 is brought into contact with the ground to secure it. The patient then moves forward following the walking aid 1, repeating the above steps to enable the patient to perform rehabilitation training.
[0028] Reference Figure 2The limiting device 2 includes a rectangular frame 23 fixedly connected to the side of the walker 1. A rotating rod 24 is rotatably connected inside the rectangular frame 23. A limiting band 21 is wrapped around the surface of the rotating rod 24. One end of the limiting band 21 is fixedly connected to a buckle. A locking frame 22 is fixedly connected to the side of the walker 1. Under the action of the locking frame 22 and the buckle, the other end of the limiting band 21 is fixed, thereby limiting the movement distance of the walker 1 and avoiding excessive movement. When the walker 1 needs to be used, it is moved to the front of the patient so that the patient can hold it with both hands. Slightly lift the walker 1 from the handles on both sides of the top, causing the rear end of the walker 1 to separate from the ground, thus allowing the casters 4 to rotate and move the walker 1. After moving to a suitable distance, bring the rear end of the walker 1 into contact with the ground to fix it in place. Then, the patient moves forward following the walker 1, repeating the above steps to enable the patient to perform rehabilitation training. One end of the rotating rod 24 is fitted with a locking rod 25. The surface of the rectangular frame 23 has a circular groove, and the locking rod 25 is inserted into the groove. Under the action of the locking rod 25, the limiting strap 21 extends to a suitable position. The length of the limiting band 21 can be fixed after adjustment, thus achieving the function of adjusting the length of the limiting band 21. A first spring 26 is sleeved on the surface of the locking rod 25. The two ends of the first spring 26 are fixedly connected to one end of the rotating rod 24 and one end of the locking rod 25, respectively. Under the action of the first spring 26, the locking rod 25 is self-locking and inserted into the inside of the circular groove. A pad 27 is fixedly connected to the side of the limiting band 21. The pad 27 is a rubber plate. Under the action of the pad 27, the limiting band 21 will not constrict the patient's legs. When the patient needs to perform rehabilitation training, the walking aid 1 is moved to the patient's leg. The device is positioned in front of the user, allowing them to grasp it. The lever 25 is pulled upwards to separate it from the circular groove. The limiting strap 21 is then pulled out from inside the rectangular frame 23. Once pulled to a suitable length, since the limiting strap 21 does not need to be precise to the millimeter, it can be limited by the structure of the lever 25 inserted into the circular groove. Under the action of the first spring 26, the lever 25 is self-locking and inserted into the circular groove. The other end of the limiting strap 21 is fixed to the frame 22 by a buckle, thus preventing the user from falling due to moving the walker 1 too far, thereby achieving the limiting effect.
[0029] Reference Figure 3The anti-slip device 3 includes a retaining ring 31 fixedly connected to the surface of the walker 1. A sleeve 32 is fitted onto the bottom of the walker 1. An annular groove is formed on the inner wall of the sleeve 32. An anti-slip block is fixedly connected to one end of the sleeve 32. Under the action of the retaining ring 31 and the annular groove, the sleeve 32 can be locked at the bottom of the walker 1, preventing the walker 1 from sliding and causing the walker 1 to move forward too far and the patient to fall. A magnetic block 35 is fixedly connected to the bottom of the walker 1, and a magnetic plate is fixedly connected to the inner wall of the sleeve 32. Under the magnetic attraction between the magnetic block 35 and the magnetic plate, the sleeve 32 can be fixed at the bottom of the walker 1. A locking rod 33 is inserted into the surface of the sleeve 32. The locking rod 33 is inserted into the interior of the walker 1. Under the action of the locking rod 33, the sleeve 32 can be firmly fixed at the bottom of the walker, preventing the walker 1 from sliding. The surface of the locking rod 33 is fitted with an anti-slip block. A second spring 34 is provided, with its two ends fixedly connected to the surface of the sleeve rod 32 and one end of the locking rod 33, respectively. Under the action of the second spring 34, the anti-slip block can be quickly replaced after wear. When the walker 1 is needed, the sleeve rod 32 is sleeved on the bottom of the walker 1. Under the action of the retaining ring 31 and the ring groove, the sleeve rod 32 can be locked on the bottom of the walker 1, preventing the walker 1 from sliding and causing the walker 1 to move too far forward and cause the patient to fall. During the sleeve installation process, under the magnetic attraction between the magnetic block 35 and the magnetic plate, the sleeve rod 32 can be fixed on the bottom of the walker 1. When the magnetic plate and the magnetic block 35 are attracted, under the action of the second spring 34, the locking rod 33 is inserted into the interior of the walker 1, thereby achieving the fixing effect and preventing the walker 1 from sliding, thus achieving the anti-slip effect.
[0030] Working principle: When the safe rehabilitation training walking aid 1 is needed, move the walking aid 1 in front of the patient, have the patient grasp the handles on both sides of the top of the walking aid 1 with both hands, and slightly lift the walking aid 1 so that the rear end of the walking aid 1 separates from the ground, thereby causing the casters 4 to rotate and move the walking aid 1. After moving to a suitable distance, bring the rear end of the walking aid 1 into contact with the ground to fix the walking aid 1. Then the patient moves forward to follow the walking aid 1, repeating the above steps to enable the patient to perform rehabilitation training. When the patient needs to perform rehabilitation training, move the walking aid 1 in front of the patient so that the patient can grasp it, pull the locking lever 25 upward to separate it from the circular groove, and pull the limiting band 21 out from the inside of the rectangular frame 23. When pulled out to a suitable length, since the limiting band 21 does not need to be accurate to millimeters, it can be limited by the structure of the locking lever 25 inserting into the circular groove. Under the action of 26, the locking rod 25 is inserted into the round groove in a self-locking manner, and the other end of the limiting band 21 is fixed to the frame 22 by the buckle, thereby preventing the patient from moving the walking aid 1 too far and falling down, thus achieving the limiting function. When the walking aid 1 needs to be used, the sleeve rod 32 is sleeved on the bottom of the walking aid 1. Under the action of the locking ring 31 and the ring groove, the sleeve rod 32 can be locked on the bottom of the walking aid 1, preventing the walking aid 1 from sliding and causing the walking aid 1 to move too far forward and causing the patient to fall down. During the sleeved process, under the magnetic attraction of the magnetic block 35 and the magnetic plate, the sleeve rod 32 can be fixed on the bottom of the walking aid 1. When the magnetic plate and the magnetic block 35 are attracted, under the action of the second spring 34, the locking rod 33 is inserted into the interior of the walking aid 1, thereby achieving the fixing function and preventing the walking aid 1 from sliding down, thus achieving the anti-slip function.
