[0032] To solve the problems existing in the prior art, the present application provides a lower limb non-weight-bearing walking brace. Specifically, as Figures 1-10 shown, the brace includes a Y-shaped bracket 1. On the Y-shaped bracket 1, there are a thigh fixing ring 11, a thigh fixing sleeve 12, and a leg sleeve assembly 13. The thigh fixing ring 11 is fixedly installed on one side of the Y-shaped bracket 1. The thigh fixing sleeve 12 is of an open design and is fixedly installed on the Y-shaped bracket 1. One side of the thigh fixing sleeve 12 is adjacent to the thigh fixing ring 11, and a fixing member 121 is provided on the other side of the thigh fixing sleeve 12. The leg sleeve assembly 13 includes a thigh fixing strap 131 and a fixing buckle 132. The first end of the thigh fixing strap 131 is fixedly installed on the thigh fixing ring 11. The second end of the thigh fixing strap 131 is provided with a first connecting portion, and a second connecting portion is provided on the surface of the thigh fixing strap 131, and the surface is located between the first end and the second end. The fixing buckle 132 includes a first mounting plate 1321 and a second mounting plate 1322. One end of the first mounting plate 1321 is rotatably connected to the second mounting plate 1322. A ring hole 13211 for passing through the thigh fixing strap is provided at the other end of the first mounting plate 1321. The other end of the second mounting plate 1322 is detachably installed with the fixing member 121. After the second end of the thigh fixing strap 131 passes through the ring hole 13211, the first connecting portion and the second connecting portion cooperate with each other. When the first connecting portion and the second connecting portion cooperate and the second mounting plate 1322 and the fixing member 121 are in the installed state, the thigh is fixed by the thigh fixing sleeve 12. When the first connecting portion and the second connecting portion cooperate and the second mounting plate 1322 and the fixing member 121 are in the disassembled state, the thigh is released by the thigh fixing sleeve 12.

[0033] The fixation and release of the thigh can be completed by the disassembly and installation of the fixing buckle 132 and the fixing member 121, which simplifies the operation steps, shortens the operation time, and improves the operation efficiency.

[0034] In an implementable solution, the cooperation between the first connecting portion and the second connecting portion can be based on the principle of Velcro. Exemplarily, the first connecting portion can be the fuzzy surface of the Velcro, and the second connecting portion can be the hook surface of the Velcro. Or, in another implementable solution, the first connecting portion can be the hook surface of the Velcro, and the second connecting portion can be the fuzzy surface of the Velcro. The first connecting portion and the second connecting portion are used to bond the thigh fixing belt 131 passing through the loop hole 13211 at a suitable position to help complete the fixation of the thigh.

[0035] It can be understood that the cooperation between the first connecting portion and the second connecting portion based on the principle of Velcro is only a preferred solution. In other implementable solutions, the first connecting portion and the second connecting portion can also be connected by a buckle or a lacing. Specifically, it can be set according to the actual situation and will not be specifically limited here.

[0036] Furthermore, in an implementable solution, the fixing member 121 can be a positioning pin, and the other end of the second mounting plate 1322 can be provided with a fixing hole. The second mounting plate 1322 is detachably installed with the fixing member 121 through the fixing hole. In another implementable solution, the fixing member 121 can be a fixing hole, and the other end of the second mounting plate 1322 can be provided with a positioning pin. The second mounting plate 1322 is detachably installed with the fixing member 121 through the positioning pin. After the positioning pin is inserted into the fixing hole, it can withstand a large shear force and pulling force, improving the strength and load-bearing capacity of the connection part, thereby providing a firm connection, ensuring the stability and reliability of the installation, not being easily loosened or detached, and the connection method is simple, the operation is convenient, and rapid installation and disassembly can be achieved, saving time and manpower. In yet another implementable solution, the fixing member 121 can be a groove, and the other end of the second mounting plate 1322 can be provided with a protrusion. The second mounting plate 1322 is detachably installed with the fixing member 121 through the protrusion. In yet another implementable solution, the fixing member 121 can be a protrusion, and the other end of the second mounting plate 1322 can be provided with a groove. The second mounting plate 1322 is detachably installed with the fixing member 121 through the groove. The cooperation between the groove and the protrusion has a self-locking function, which can be automatically locked after installation to prevent accidental detachment and improve the stability of the connection.

[0037] It can be understood that the fixing buckle 132 and the fixing member 121 can also adopt detachable connection methods such as a spring and a hook, a buckle and a button.

[0038] Furthermore, as Figure 2 and Figure 3As shown, in an implementable solution, the fixed buckle 121 further includes a third mounting plate 1323. One end of the third mounting plate 1323 is rotatably connected to the first mounting plate 1321, and the other end of the third mounting plate 1323 is rotatably connected to the second mounting plate 1322. In the first state, the third mounting plate 1323 is stacked on the second mounting plate 1322 through the stacking member 1324. By opening and closing the stacking member 1324 stacked on the second mounting plate 1322, the length of the thigh fixing strap 131 can be further adjusted.

[0039] Further, continue to refer to Figure 2 and Figure 3 The stacking member 1324 includes a first stacking portion and a second stacking portion. The first stacking portion is provided on the third mounting plate 1323, and the second stacking portion is provided on the second mounting plate 1322. In the first state of the third mounting plate 1323, the first stacking portion cooperates with the second stacking portion so that the third mounting plate 1323 is stacked on the second mounting plate 1322, and the third mounting plate 1323 and the second mounting plate 1322 are locked to each other. The first stacking portion restricts the relative rotation of the second mounting plate 1322 with respect to the third mounting plate 1323; when the third mounting plate 1323 is in the second state, the first stacking portion releases the relative rotation of the second mounting plate 1322 with respect to the third mounting plate 1323, and the third mounting plate 1323 and the second mounting plate 1322 are unlocked from each other. Specifically, the first stacking portion and the second stacking portion cooperate with each other to hide the connection portion between the second connecting plate 1322 and the third connecting plate 1323, so that the second mounting plate 1322 and the third mounting plate 1323 are integrally stacked on each other, making the entire fixed buckle 132 more beautiful and tidy.

[0040] Further, referring to Figures 1-8 a calf fixing mechanism 14 is also installed on the Y-shaped bracket 1. The calf fixing mechanism 14 is installed on the Y-shaped bracket 1 and is located below the thigh fixing sleeve 12. The calf fixing mechanism 14 includes a calf fixing strap 141 and calf fixing rings 142 provided on both sides of the Y-shaped bracket 1. One end of the calf fixing strap 141 is fixed to the calf fixing ring 142 on one side of the Y-shaped bracket 1. The other end of the calf fixing strap 141 is provided with a third connecting portion, and a fourth connecting portion is provided on the surface of the calf fixing strap 141. After the other end of the calf fixing strap 141 passes through the calf fixing ring 142 on the other side of the Y-shaped bracket 1 and is folded back, the third connecting portion cooperates with the fourth connecting portion to complete the fixation of the calf. The calf fixing mechanism 14 is used in cooperation with the thigh fixing sleeve 12 and the Y-shaped bracket 1 to form a complete support system, providing comprehensive leg fixation and support functions, enabling the patient to perform safe, effective, and convenient walking exercises on the premise of being free from weight-bearing.

[0041] Further, as Figure 4 shown, the Y-shaped bracket 1 includes a bottom rod 17 and two support rods 15 that extend in a Y-shape from the top of the bottom rod 17. Preferably, the two support rods 15 and the bottom rod 17 are adjustably connected by a connecting block 16. Looking from the side, the two support rods 15 extend obliquely upward from the top of the bottom rod 17, which is beneficial for fixing the entire leg of the user on the Y-shaped bracket 1 with an angle greater than 90° between the thigh and the calf.

[0042] Specifically, in an implementable solution, both sides of the connecting block 16 are fixedly connected to the two support rods 15. The bottom rod 17 is provided with a plurality of adjustment holes along its length from top to bottom. A fixing hole is provided in the middle part of the connecting block 16. A bolt passes through the adjustment hole and the fixing hole to fix the support rod 15 and the bottom rod 17. By adjusting the positions where the adjustment holes at different positions are fixed to the fixing hole, the overall dimension length of the Y-shaped bracket 1 can be adjusted, which can be suitable for people with different leg lengths.

[0043] Further, as Figure 5 and Figure 9 shown, a supporting plate 171 is further provided at the bottom of the bottom rod 17. The supporting plate 171 is connected to the bottom of the bottom rod 17 through a torsion spring 1711. Preferably, the supporting plate 171 is detachably connected to the bottom rod 17. The supporting plate 171 is used to support the patient's foot to avoid the uncomfortable feeling caused by the patient's foot being in a suspended position. And when the foot is placed on the supporting plate 171 and the front sole exerts force on the supporting plate 171, through the deformation of the torsion spring 1711, the supporting plate 171 can rotate relative to the bottom rod. And when the front sole gives up exerting force on the supporting plate, the deformation of the spring disappears and returns to its original state, and the supporting plate is perpendicular to the bottom rod. Preferably, a shoe strap 1712 is further provided on the supporting plate 171. Specifically, referring to Figure 9 , after the sole of the foot is supported on the supporting plate 171, one end of the calf fixing strap 141 is fixed to the calf fixing ring 142 on one side of the Y-shaped bracket 1. The other end of the calf fixing strap 141 passes through the shoe strap 1712 and the calf fixing ring 142 on the other side of the Y-shaped bracket 1 and then is folded back. The third connecting part 1411 cooperates with the fourth connecting part 1412 to complete the fixation of the calf. After the calf fixing strap 141 passes through the shoe strap 1712 and the calf fixing ring 142 of the Y-shaped bracket 1, the patient's foot can be fixed more firmly, reducing the risk of displacement and loosening. Preferably, the elasticity of the shoe strap 1712 is adjustable, which can reduce the direct pressure of the calf fixing strap 141 on the skin, reduce friction and discomfort, and improve the overall comfort. The dual design of the calf fixing strap 141 and the shoe strap 1712 ensures safety during exercise or rehabilitation training, prevents accidental detachment or slippage, and improves the safety guarantee of the patient.

[0044] Further, continue to refer to Figure 10, the calf fixing strap 141 realizes double fixation of the sole through the shoe cover strap 1712 and winding around the lining board 171, further improving the fixation stability of the sole.

[0045] Furthermore, continue to refer to Figure 11 , when a certain swing amplitude is required for the sole, the calf fixing strap 141 can be based on Figure 11 the bundling method to realize the restraint of the calf and the support of the sole through the calf fixing strap 141. Since the calf fixing strap 141 has a certain elasticity, by supporting and lifting the sole with the calf fixing strap, the sole can swing by a certain amplitude by using the elastic effect of the calf fixing strap 141.

[0046] For the lower limb non-weight-bearing walking brace of this solution, a fixing member 121 is provided on the thigh fixing sleeve 12, and a fixing buckle 132 that can cooperate with the fixing member 121 is configured. The fixation and loosening of the thigh can be completed by the disassembly and installation of the fixing buckle 132 and the fixing member 121, which simplifies the operation steps, shortens the operation time, and improves the operation efficiency.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
