[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0029] Reference Figure 1-6 As shown, the thoracic and lumbar support structure of a walker described in the present invention includes a frame 1, a lumbar support device 2, a left support device 3, a right support device 4, and four sets of universal wheels 5, and is characterized in that: the lumbar support device 2 includes a first U-shaped plate 21 movably arranged on the frame 1, three second springs 22 whose two ends are respectively fixed to the first U-shaped plate 21 and the frame 1, a second U-shaped plate 23 movably arranged on the frame 1 and located above the first U-shaped plate 21, a screw 24 rotatably arranged on the first U-shaped plate 21 and threadedly engaged with the second U-shaped plate 23, an elastic waist belt 25 located in the middle and lower part of the first U-shaped plate, and three drawstrings 26 with one end fixed to the second U-shaped plate 23 and the other end fixed to the elastic waist belt.
[0030] When using the walker, according to the patient's height, the screw 24 is turned to appropriately adjust the height of the second U-shaped plate 23, driving the three pull ropes 26 to move up and down, thereby driving the elastic belt 25 to move up and down until it is suitable for the patient's height. During walking, since the three second springs 22 are respectively fixed to the first U-shaped plate 21 and the frame 1, the first U-shaped plate 21 can move in the vertical direction of the frame 1, adapting to the floating center of gravity of the patient during walking, and providing good support for the patient's waist.
[0031] The left supporting device 3 has the same structure as the right supporting device 4; the right supporting device 4 includes a first telescopic rod 41 which can be lifted and lowered on the frame 1, a second telescopic rod 42 which can be lifted and lowered on the frame 1, a first slide rail 43 fixed on the first telescopic rod 41, a second slide rail 44 fixed on the second telescopic rod 42, a first slider 45 movably arranged in the first slide rail 43, a second slider 46 movably arranged in the second slide rail 44, a third spring 47 whose two ends are respectively fixed on the first slide rail 43 and the first slider 45, a fourth spring 48 whose two ends are respectively fixed on the second slide rail 44 and the second slider 46, a support rod 49 fixed on the first slider 45 and the second slider 46, an airbag 50 fixedly sleeved on the support rod, and a pressing component 51 provided on one side of the frame 1 and used to drive the first telescopic rod and the second telescopic rod to lift and lower.
[0032] Taking the right support device 4 as an example to illustrate the beneficial effects, when using the walker, adjust the first telescopic rod 41 and the second telescopic rod 42 to a suitable height, move the airbag 50 and the support rod 49, and the first slider 45 and the second slider 46 also move at the same time, so that the airbag 50 is in a suitable position; according to the above structure, the left support device 3 and the right support device 4 can provide support while ensuring comfort.
[0033] Specifically, the lumbar support device 2 also includes a back plate 27 rotatably arranged on the first U-shaped plate 21, a baffle 28 engaged with the back plate 27, a slot 29 provided on the inner side of the back plate, and a first spring 271 whose two ends are respectively fixed to the back plate 27 and the baffle 28.
[0034] When the patient needs to use the walker, the baffle 28 is pulled out from the slot 29, the back plate 27 is opened, the patient enters the walker and after the preparation work is completed, the back plate 27 is closed, and the baffle 28 is inserted into the slot 29 to fix the back plate 27. Since the back plate 27 is rotatably arranged on the first U-shaped plate 21, the back plate 27 can move together with the first U-shaped plate 21 during walking. The setting of the back plate 27 serves to limit the patient.
[0035] Specifically, the elastic waistband 25 includes a waistband body 251, a first female buckle 252 provided at one end of the waistband body 251, and a first sub-buckle 253 provided at the other end of the waistband body 251; the first female buckle 252 and the first sub-buckle 253 are a snap-fit structure.
[0036] Specifically, the elastic waist belt 25 also includes a left leg strap 254, a right leg strap 255 and a connecting strap 256. The connecting strap 256 is used to fix the left leg strap 254 and the right leg strap 255. The left leg strap 254 and the right leg strap 255 are symmetrically arranged and have the same structure. The left leg strap 254 includes a retractable strap 257 and a second female buckle 258 and a second sub-buckle 259 arranged on the retractable strap 256.
[0037] The patient engages the first female buckle 252 and the first child buckle 253 to make the elastic waist belt body 251 fit the patient's waist, and engages the second female buckle 258 and the second child buckle 259 to make the left leg strap 254 support the left leg, and the right leg strap 255 support the right leg in the same way. The connecting belt 256 makes the positions of the left leg strap 254 and the right leg strap 255 relatively fixed, providing good support for the legs, thereby also providing support for the waist.
[0038] Specifically, the first slide rail 43 and the second slide rail 44 are inclined.
[0039] The first slide rail 43 and the second slide rail 44 are inclined inwardly, so that the air bag 50 tends to move closer to the patient's body, fits the patient's body better, and enables the walker to provide good support.
[0040] Specifically, the pressing assembly 51 includes a guide rod 511 fixed on the frame 1, a pressing frame 512 movably mounted on the guide rod 511, a first rack 513 and a second rack 514 fixed at both ends of the pressing frame 512, a third rack 515 fixed on the first slide rail 43, a fourth rack 516 fixed on the second slide rail 44, a first gear 517 rotatably mounted on the frame 1 and respectively engaged with the first rack 513 and the third rack 515, a second gear 518 rotatably mounted on the frame 1 and respectively engaged with the second rack 514 and the fourth rack 516, and a handle 519 fixed at both ends on the pressing frame 512.
[0041] When the patient walks, the patient holds the handle 519, giving downward force to the lower pressure frame 512, and the lower pressure frame 512 moves downward along the guide rod 511, while driving the first rack 513 and the second rack 514 to move downward, causing the first gear 517 and the second gear 518 to rotate, driving the third rack 515 and the fourth rack 516 to move upward, and the first slide rail 43 and the second slide rail 44 move upward accordingly, and the airbag 50 moves upward, providing upward support for the patient.
[0042] Specifically, the pressing assembly 51 further includes a fifth spring 520, the two ends of which are respectively fixed to the frame body 1 and the pressing frame 512. After use, the pressing frame 512 is reset under the action of the spring 520.
