Specific implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1 to 5 , an articular limiting device is provided in an embodiment of the present invention, including: a protective sleeve 1, a front strap 2 is connected to the front side of the protective sleeve 1, a rear strap 10 is connected to the back surface of the left end of the protective sleeve 1, and a lower strap 9 is connected to the right end of the protective sleeve 1. Collars 4 are installed between the rear strap 10, the lower strap 9 and the front strap 2 and the protective sleeve 1. A protective cover 3 is installed on the side surface of the protective sleeve 1, and a semi-circular gear 101 is arranged inside the protective cover 3. A movable shaft 102 is arranged between the semi-circular gear 101 and the protective sleeve 1. The semi-circular gear 101 and the protective sleeve 1 are integrally connected, and the semi-circular gear 101 and the protective cover 3 are movably connected through the movable shaft 102;
[0024] Specifically, the protective sleeve 1 is arranged in an S shape, which can protect and position the knee joint of the leg. At the same time, in cooperation with the use of the rear strap 10, the lower strap 9 and the front strap 2, the wearing of the protective sleeve 1 is completed. The protective sleeve 1 is divided into upper and lower parts, and the middle is in a separated state and is connected by the meshing of two groups of semi-circular gears 101. By using the mutual meshing between the semi-circular gears 101, the movement of the protective sleeve 1 can be realized to help the joint move.
[0025] An elastic sticker 5 is connected to the surface of the protective sleeve 1, and a fixed leg sleeve 6 is installed at the upper end of the elastic sticker 5. A hanging buckle 7 is arranged on the surface of the fixed leg sleeve 6, and a button 8 matching with the hanging buckle 7 is arranged on the upper surface of the elastic sticker 5;
[0026] Specifically, the elastic sticker 5 is made of elastic material, which can fit the patella on the front side of the knee joint. The elastic sticker 5 wraps and protects the patella to prevent the patella from being injured.
[0027] The rear side of the protective sleeve 1 is movably connected with a movable support 11, and one end of the movable support 11 is movably connected with a movable rod 12. A rotating shaft 13 for rotation is arranged between the movable rod 12 and the movable support 11. A locking rod 17 is connected to the surface of the movable support 11. A first collar seat 14 is fixedly arranged on the surface of the movable rod 12, and a second collar seat 15 is installed on one side of the first collar seat 14. A elastic hook 16 is connected to the surface of the second collar seat 15. The movable rod 12 and the movable support 11 are rotationally connected through the rotating shaft 13, and the locking rod 17 and the movable support 11 are movably connected;
[0028] Specifically, the movable support 11 and the movable rod 12 are at the rear side of the protective sleeve 1, corresponding to the back of the knee joint. By using the folding rotation between the movable support 11 and the movable rod 12, it helps the joint to move. And a locking rod 17 is connected to the movable support 11. Through the cooperation between the locking rod 17 and the first collar seat 14 and the second collar seat 15, different locking methods can be selected. Selecting the first collar seat 14 can lock the movable support 11 and the movable rod 12, keeping the movable support 11 and the movable rod 12 straight and playing a role of fixed support. Selecting the second collar seat 15 and connecting it with the elastic hook 16 on the second collar seat 15, by using the elasticity of the elastic hook 16 and the positioning of the locking rod 17, the movement range of the movable support 11 and the movable rod 12 can be restricted.
[0029] The working principle of the utility model is:
[0030] When using the utility model, first, wear the protective sleeve 1 on the joint, and successively use the rear strap 10, the lower strap 9 and the front strap 2 to tighten and wear the protective sleeve 1. Align the elastic patch 5 with the position of the patella, and use the elasticity of the elastic patch 5 to pull the elastic patch 5 upward, and use the button 8 and the hanging buckle 7 to connect the elastic patch 5 with the fixed leg sleeve 6. Secondly, when the leg joint moves, by using the meshing between the semi-circular gears 101, the movement of the protective sleeve 1 can be realized. Then, when the joint does not need to move, hang the locking rod 17 on the first collar seat 14, and the locking rod 17 blocks the movable connection point between the movable support 11 and the movable rod 12, which can prevent the rotating shaft 13 from affecting the rotation between the movable support 11 and the movable rod 12, keeping the movable support 11 and the movable rod 12 straight and playing a role of fixed support. Again, when the joint needs to have limited movement, select the second collar seat 15 and connect it with the elastic hook 16 on the second collar seat 15. When moving, the locking rod 17 can not only use its own length to limit the movement of the movable support 11 and the movable rod 12, but also use the elasticity of the elastic hook 16 to maintain a certain range of elastic movement, thereby restricting the movement range of the movable support 11 and the movable rod 12. Since the large movement range is limited, the gait will change accordingly. By controlling the movement range of the movable support 11 and the movable rod 12, it is beneficial to realize the control of the gait.
[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
