DETAILED DESCRIPTION

[0024] like Figure 1-3As shown, a walking aid provided by the utility model includes: a waist strap 10, a force plate 20, a correction belt 30 and a foot fixing part 40, wherein the force plate 20 is arranged on the waist strap 10, and one side of the force plate 20 is close to the waist strap 10; the correction belt 30 is connected to the upper end of the force plate 20, and when the correction belt 30 is subjected to a downward force, the force plate 20 forms a lever structure and fits against the waist strap 10; the foot fixing part 40 is connected to the end of the correction belt 30 away from the force plate 20.

[0025] Compared with the prior art, the walking aid provided by the utility model has a larger area of ​​the force-bearing plate 20 that is tightly attached to the surface of the waist strap 10 under the action of the downward force of the correction belt 30, which plays a buffering role, thereby dispersing the force, solving the problem of excessive concentration of force on the waist, and improving wearing comfort.

[0026] In one embodiment, the waist strap 10 is provided with an inelastic belt 101 with both ends fixed on the waist strap 10, the force plate 20 is provided on the inelastic belt 101, and an inflatable airbag 102 is provided between the waist strap 10 and the inelastic belt 101, and the outer side surface of the inflatable airbag 102 is close to the force plate 20.

[0027] Specifically, when the force-bearing plate 20 is subjected to the downward force of the correction belt 30, a larger area of ​​the force-bearing plate 20 is closely attached to the surface of the inflatable airbag 102, and the inflatable airbag 102 plays a buffering role. The force-bearing plate 20 cooperates with the inflatable airbag 102 to further disperse the force and further improve the wearing comfort. In addition, the inflatable airbag 102 can also adjust the internal air pressure to adapt to the wearing of different users, and can also adjust the tightness of the waist strap 10 in a small range.

[0028] In this embodiment, the force-bearing plate 20 is provided with a protrusion 202 away from the inflatable airbag 102, the protrusion 202 is provided with a second through-hole 203 for fixing the correction belt 30, and the force-bearing plate 20 is provided with a through-hole 201 for the inelastic belt 101 to pass through.

[0029] Specifically, the protrusion 202 is in the shape of an elongated strip, and the protrusion 202 is integrally formed with the force-bearing plate 20, and is located at the upper end of the force-bearing plate 20; the second perforation 203 is a long strip hole, and its extension direction is perpendicular to the extension direction of the perforation 1 201. When the protrusion 202 is subjected to the tension of the correction belt 30, the part of the force-bearing plate 20 located below the protrusion 202 is like a rotating arm that is tightly attached to the surface of the inflatable airbag 102, so that the force-bearing plate 20 and the inflatable airbag 102 can be better exerted. The inflatable airbag 102 has a cushioning effect; the inelastic band 101 is made of nylon webbing, the perforation 201 is a long strip hole, and its extension direction is parallel to the side of the force-bearing plate 20 close to the inflatable airbag 102. The inelastic band 101 passes through the perforation 201, so that the force-bearing plate 20 can adjust its position along the inelastic band 101 to improve the wearing adaptability. At the same time, the force-bearing plate 20 and the inelastic band 101 are more firmly connected, and the force-bearing surfaces of the two are larger.

[0030] In one embodiment, the correction strap 30 includes an inelastic strap 2 302 with adjustable length, an inelastic strap 3 303 connected to one end of the inelastic strap 2 302 , and an elastic strap 304 with two ends respectively fixed to the inelastic strap 2 302 and the inelastic strap 3 303 , and one end of the inelastic strap 3 303 is connected to the foot fixing portion 40 .

[0031] Specifically, the inelastic belt 2 302 and the inelastic belt 3 303 are made of nylon webbing, and the elastic belt 304 is made of latex or woven elastic. By adjusting the extension or shortening of the inelastic belt 3 303, the degree to which the elastic belt 304 participates in the stretching can be adjusted. If the adjusted length of the inelastic belt 3 303 is less than or equal to the initial length of the elastic belt 304, the correction belt 30 is inelastic; if the adjusted length of the inelastic belt 3 303 is greater than the original length of the elastic belt 304, the correction belt 30 is elastic. Through the above adjustment, the elastic belt 304 can be adjusted to the inelastic mode according to the patient's needs to completely limit the hyperextension of the knee; it can be adjusted to the elastic belt mode to adjust the degree of auxiliary hip flexion and knee flexion.

[0032] In one embodiment, a connecting belt 21 is provided at the end of the correction belt 30, and the correction belt 30 is fixedly connected to the force-bearing plate 20 through the connecting belt 21. Specifically, the second inelastic belt 302 is connected to one end of the connecting belt 21, and the connecting belt 21 is a nylon webbing passing through the second perforation 203 and presents a closed surrounding structure.

[0033] In one embodiment, the connecting belt 21 is connected to the second inelastic belt 302 via a backpack buckle 301, which is composed of a detachable buckle and a Japanese buckle, thereby achieving rapid adjustment of the length of the second inelastic belt 302 and allowing rapid assembly and disassembly of the correction belt 30.

[0034] In one embodiment, the second inelastic band 302 is connected to the third inelastic band 303 via a Japanese buckle 305 , so that the length of the third inelastic band 303 can be quickly adjusted.

[0035] In another embodiment, the number of correction belts 30 is two, one end of each correction belt 30 is fixedly connected to the connecting belt 21 through a backpack buckle 301, and the other end is fixed to the foot fixing part 40. In this way, the problem of internal rotation of the hip joint that occurs when walking can be solved by setting two correction belts 30 in an eight-shaped arrangement. When in use, the two correction belts 30 are cross-wound around the legs. When it is necessary to limit the internal rotation of the hip joint, the corresponding correction belt 30 needs to be tightened to make the hip joint externally rotated; in addition, the angles of internal and external rotation of the hip joint can be adjusted by adjusting the correction belt 30 running on the inner side of the thigh and the correction belt 30 running on the outer side of the thigh.

[0036] In this embodiment, a manual inflatable ball 103 is provided on the inflatable airbag 102, so that the air pressure can be manually adjusted by inflating, which improves the convenience of use. Furthermore, the inflatable airbag 102 and the manual inflatable ball 103 are connected by a hose.

[0037] In this embodiment, the side of the inflatable airbag 102 connected to the waist strap 10 is a flat surface, so that the contact surface between the inflatable airbag 102 and the waist strap 10 is larger, and the connection can be more secure, and it can also play a more sufficient buffering role, and the wearing comfort will be higher. Of course, the inflatable airbag 102 can also be fixedly connected to the force plate 20, specifically by gluing or hot gluing.
