[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1-5 The utility model provides an embodiment: an auxiliary walking device for patients with cardiovascular disease, comprising a waist belt 1 and two support crutches 20, both ends of the waist belt 1 are fixedly connected with elastic belts 2, the other end of the left elastic belt 2 is fixedly connected with a mounting box 3, the interior of the mounting box 3 is provided with a mounting groove 4, the side wall of the mounting groove 4 is provided with two clamping holes 5, the outer side of the mounting box 3 is fixedly connected with two U-shaped blocks 6, the interior of the U-shaped block 6 is slidably connected with a push rod 7, the other end of the right elastic belt 2 is fixedly connected with a connecting block 8, the outside of the connecting block 8 is fixedly connected with a mounting block 9, the interior of the mounting block 9 is slidably connected with two movable plates 10, the outside of the movable plate 10 is fixedly connected with a clamping block 11, and the inner wall of the mounting block 9 is fixedly connected There are two springs 12. The belt 1 is put on the user's waist, and the mounting block 9 is aligned with the mounting slot 4 and directly inserted. When the inclined surface of the clamping block 11 contacts the inner wall of the mounting slot 4, it will be squeezed and will shrink into the inside of the mounting block 9. At this time, the movable plate 10 will squeeze the spring 12, so that the spring 12 is in a compressed state. When the mounting block 9 is completely inserted into the inside of the mounting slot 4, the elastic force of the spring 12 will make the movable plate 10 push the clamping block 11 to pop out quickly and engage in the inside of the clamping hole 5. In this way, the belt 1 is put on. When it needs to be removed, the user can press the two push rods 7 at the same time to shrink the clamping block 11 and pull the mounting block 9 out from the inside of the mounting slot 4, and untie the constraints of the two waist elastic bands 2 in turn.
[0030] The outside of the waist belt 1 is fixedly connected to a power box 13, and the outside of the power box 13 is fixedly connected to two connecting plates 14, the other end of the connecting plate 14 is rotatably connected to a thigh driving plate 15, the other end of the thigh driving plate 15 is fixedly connected to a joint plate 16, and the other end of the joint plate 16 is rotatably connected to a calf driving plate 17, and the outside of the supporting crutch 20 is fixedly connected to a handle 21, and a plurality of controllers 22 are installed on the outside of the handle 21. The user can issue instructions to the internal driving structure of the thigh driving plate 15 and the calf driving plate 17 by pressing the controller 22, so that the thigh driving plate 15 and the calf driving plate 17 rotate to assist the user to complete the squatting and foot-lifting walking movements, allowing the user to perform autonomous walking training without the need for caregivers to support, and is more convenient to use.
[0031] The outer sides of the thigh driving plate 15 and the calf driving plate 17 are fixedly connected with leggings 19, and the outer side of the joint plate 16 is fixedly connected with knee pads 18. The knee pads 18 can be used to protect the knees, and the leggings 19 fix the thigh driving plate 15 and the calf driving plate 17 to the outer sides of the user's legs.
[0032] The outer side of the push rod 7 is slidably connected to the inner wall of the clamping hole 5, which facilitates the push rod 7 to squeeze the clamping block 11 for contraction. The outer side of the mounting block 9 is slidably connected to the inner wall of the mounting groove 4, making it easy to insert the mounting block 9 into the interior of the mounting groove 4.
[0033] The outside of the clamping block 11 is clamped in the inside of the clamping hole 5, and the mounting block 9 is fixed in the inside of the mounting groove 4. The other end of the spring 12 is fixedly connected to the outside of the movable plate 10, and the elastic force of the spring 12 can quickly reset the movable plate 10.
[0034] A driving structure is installed inside the thigh driving plate 15 and the calf driving plate 17. The driving structure is an existing mature technology and is used to enable the thigh driving plate 15 and the calf driving plate 17 to complete the rotation action, which will not be repeated here.
[0035] Two elastic clamps 23 are fixedly connected to the outer side of the support crutch 20. The elastic clamps 23 are used to be mounted on the outer periphery of the user's arm.
[0036] Working principle: When in use, the user can wear the auxiliary walking device, first, the leg can be passed through the leggings 19 outside the thigh driving plate 15, then through the knee pads 18, and finally through the leggings 19 outside the calf driving plate 17. The knee pads 18 can be used to protect the knees, and the leggings 19 fix the thigh driving plate 15 and the calf driving plate 17 on the outside of the user's legs. Then the belt 1 is put on the user's waist, and the mounting block 9 is aligned with the mounting slot 4 and directly inserted. When the inclined surface of the card block 11 contacts the inner wall of the mounting slot 4, it will be squeezed and will shrink to the inside of the mounting block 9. At this time, the movable plate 10 will squeeze the spring 12, so that the spring 12 is in a compressed state. When the mounting block 9 is fully inserted into the inside of the mounting slot 4, the elastic force of the spring 12 will cause the movable plate 10 to push the card block 11 to pop out quickly, and The user can then hold the handle 21 and support his body with the support crutch 20, and can issue instructions to the internal drive structure of the thigh drive plate 15 and the calf drive plate 17 by pressing the controller 22, so that the thigh drive plate 15 and the calf drive plate 17 rotate to assist the user in squatting and walking with the feet lifted, so that the user can perform autonomous walking training without the need for caregivers to help him, and it is convenient to use. When it needs to be removed, the user can press the two push rods 7 at the same time to shrink the card block 11, and pull the mounting block 9 out of the mounting groove 4, untie the two waist elastic bands 2 in turn, and then pull the legs out of the leggings 19 and the knee pads 18.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
