[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0020] Example 1: like Figures 1 to 7 As shown, a wheelchair designed for exercise and massage in patients with leg injuries includes a wheelchair 1 and a seat cushion 2 mounted on the wheelchair 1. A massage mechanism 31 and an exercise mechanism 32 are mounted on the wheelchair 1 and seat cushion 2. The massage mechanism 31 includes a rotating shaft 311 rotatably mounted at the lower end of the seat cushion 2. A connecting rod 312 is movably mounted on the rotating shaft 311. A support connecting rod 317 is located below the connecting rod 312. A connecting push plate 318 is connected to the outer wall of one end of the support connecting rod 317. A rotating shaft 3110 is mounted on the connecting push plate 318. A massage roller 3111 is connected to the outer wall of the rotating shaft 3110. The massage roller 3111 is used to perform rolling massage on the patient's lower leg. The exercise mechanism 32 includes a support leg plate 325 connected to the outer wall of the rotating shaft 311. An electric push rod 322 is mounted at the bottom of the seat cushion 2. The electric push rod 322 is used to push the support leg plate 325 to rotate, thereby causing the patient's lower leg to swing, completing the exercise.
[0021] like Figures 1 to 7As shown, in a specific embodiment, the massage mechanism 31 includes a support plate 313 connected to the bottom end of a connecting rod 312. A groove is formed at the bottom end of the support plate 313. A sliding rod 314 is connected to the inner wall of the groove. A supporting sliding rod 316 is slidably mounted on the outer wall of the sliding rod 314. A spring 315 is connected to the outer wall of the supporting sliding rod 316. The end of the spring 315 away from the supporting sliding rod 316 is connected to the inner wall of the groove. A connecting rod 319 is connected to the outer wall of a connecting push plate 318. A rotating shaft 3110 is rotatably mounted on the end of the connecting rod 319 away from the connecting push plate 318. The outer wall of one side of the rotating shaft 3110... A plug block 3112 is provided for connection. A sprocket 3113 is connected to the outer wall of the rotating shaft 3110. A chain belt 3114 is engaged with the sprocket 3113. A fixing rod 3120 is connected to the bottom end of the seat cushion 2. A rack 3119 is connected to the bottom end of the fixing rod 3120. A gear 3118 is engaged on the rack 3119. A connecting sleeve 3116 is connected to the outer wall of one side of the gear 3118. The end of the connecting sleeve 3116 away from the gear 3118 is rotatably mounted on the outer wall of the support leg plate 325. A locking hole 3117 is opened on the inner wall of the connecting sleeve 3116. A locking groove 3115 is opened on the outer wall of the support leg plate 325.
[0022] like Figures 1 to 7 As shown, further, a limiting rod 3121 is connected to the bottom end of the seat cushion 2, and a limiting block 3122 is connected to the bottom end of the seat cushion 2 on one side of the limiting rod 3121; a through groove is opened on the outer wall of the connecting sleeve 3116, and the through groove opened on the outer wall of the connecting sleeve 3116 is set to correspond to the slot 3115 when the gear 3118 is in the initial position. In this setting, the limiting block 3122 can limit the position of the support leg plate 325 to prevent the support leg plate 325 from continuously moving backward and rotating. At the same time, the limiting rod 3121 can be tightly attached to its outer wall after the rotating shaft 3110 is reset and moved, thereby limiting its friction and preventing it from rotating and causing the insert 3112 to leave the initial insertion position and affect the subsequent engagement with the slot 3117.
[0023] Furthermore, the rack 3119 is arc-shaped, and the center of the arc of the rack 3119 is consistent with the rotation center of the rotating shaft 311. In this configuration, by setting the rotation center of the rack 3119 and the rotating shaft 311 to be consistent, the gear 3118 can rotate along the rack 3119, thereby synchronously driving the massage roller 3111 to rotate and massage during the exercise process of the support leg plate 325 rotating.
[0024] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 7As shown, a wheelchair for facilitating leg injury patient exercise and massage, the exercise mechanism 32 includes a mounting rod 321 connected to the bottom end of the seat cushion 2, an electric push rod 322 is mounted on the mounting rod 321, the output end of the electric push rod 322 is connected to a fixed connecting plate 323, and the outer wall of one side of the fixed connecting plate 323 is connected to a push wheel 324.
[0025] As shown in the specific embodiment, the number of support leg plates 325 is two, and the support leg plates 325 are symmetrically distributed on the wheelchair 1. Figures 1 to 7
[0026] As shown in the specific embodiment, the number of support leg plates 325 is two, and the support leg plates 325 are symmetrically distributed on the wheelchair 1. Figures 1 to 7 Further, the support leg plate 325 is provided with a placing groove relative to one end of the outer wall of the clamping groove 3115, and the placing groove is an inner arc shape.
[0027] The implementation principle of the wheelchair for facilitating leg injury patient exercise and massage is as follows: first, the patient is helped to sit on the wheelchair 1, so that the lower limbs are arranged on the two support leg plates 325, then the electric push rod 322 is started, the output end of the electric push rod 322 drives the fixed connecting plate 323 and the push wheel 324 to move synchronously, the push wheel 324 continuously moves to contact and extrude the connecting push plate 318, the connecting push plate 318 drives the support connecting rod 317 to move synchronously, the support connecting rod 317 moves to drive the support sliding rod 316 on the top thereof to slide along the outer wall of the sliding rod 314, and the spring 315 is stretched and elongated during the sliding of the support sliding rod 316; the connecting push plate 318 drives the shaft two 3110, the massage roller 3111 and the insert block 3112 on the outer wall of the shaft two 3110 to move, the shaft two 3110 is moved to be clamped in the clamping groove 3115 on the side outer wall of the support leg plate 325, and the insert block 3112 on the outer wall of the shaft two 3110 is inserted into the inner wall of the clamping hole 3117, so that the shaft two 3110 and the connecting sleeve 3116 are limited and clamped, and the massage roller 3111 on the outer wall of the shaft two 3110 is clamped and installed in the support leg plate 325 and contacts the lower limbs of the patient. After the continuous extension of the output end of the electric push rod 322, the connecting push plate 318 and the support leg plate 325 are continuously pushed and rotated outward along the outer wall of the rotating shaft one 311. With the rotation of the support leg plate 325, the gear 3118 on the outer wall is synchronously rotated. At this time, the gear 3118 is meshed and rotated along the stroke direction of the rack 3119. In this way, the connecting sleeve 3116 is synchronously rotated by the gear 3118. Since the connecting sleeve 3116 is connected with the plug block 3112 through the clamping hole 3117 at this time, the connecting sleeve 3116 can synchronously rotate the rotating shaft two 3110. With the rotation of the rotating shaft two 3110, the massage roller 3111 on the outer wall is rotated. At the same time, the rotating shaft two 3110 rotates the sprocket 3113 to rotate the chain 3114, thereby rotating the remaining rotating shaft two 3110 and the massage roller 3111. In this way, the massage roller 3111 is rotated to roll and massage the lower leg of the patient. Then, the output end of the electric push rod 322 is retracted. In this way, the support leg plate 325 and the massage roller 3111 on the connecting push plate 318 are reset and rotated. At this time, the gear 3118 is reciprocatingly rotated along the rack 3119. In this way, the massage roller 3111 is reciprocatingly controlled to continuously roll and massage the lower leg of the patient.
[0028] When rolling and massaging the lower leg of the patient, the support leg plate 325 is rotated by the rotating shaft one 311. In this way, the lower leg of the patient is reciprocatingly rotated, thereby achieving the purpose of exercising the lower leg of the patient.
[0029] When the exercise and massage are finished, the output end of the electric push rod 322 is retracted to the initial position. In this way, the push wheel 324 is moved to release the extrusion on the connecting push plate 318. At this time, the support leg plate 325 is rotated to the initial position and contacts the outer wall of the limiting block 3122, thereby being limited by the limiting block 3122. At this time, the spring 315 is reset and moves the support slide rod 316. With the reset movement of the support slide rod 316, the lower support connecting rod 317 is reset and moved. The support connecting rod 317 synchronously resets and moves the connecting push plate 318. In this way, the connecting push plate 318 moves the rotating shaft two 3110 and the massage roller 3111. At this time, the rotating shaft two 3110 is separated from the inside of the clamping groove 3115 in the support leg plate 325. The plug block 3112 on the outer wall is separated from the inside of the clamping hole 3117. In this way, when the exercise and massage are not needed, the massage roller 3111 is prevented from being pressed on the lower leg of the patient in the support leg plate 325, thereby avoiding discomfort. Finally, the rotating shaft two 3110 will reset to the position of the limiting rod 3121 and adhere to the outer wall thereof, so that the rotating shaft two 3110 is frictionally limited, and rotation of the rotating shaft two 3110 is prevented to cause the plug 3112 to lose position and affect the clamping between the plug 3112 and the clamping hole 3117.
[0030] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
