Description

Technical Field

[0001] The utility model belongs to the technical field of wheelchairs, and specifically relates to a rhythmic wheelchair for cardiovascular disease rehabilitation. Background Technique

[0002] Vertical rhythm can change the body's musculoskeletal nervous system through the physical action of gravity. When a person does vertical up-and-down rhythm, it will cause moderate blood flow shear force in the blood vessels. The blood flow shear force stimulates the vascular endothelial cells to produce the hormone "nitric oxide" beneficial to the human body, and nitric oxide is a vasodilator and dredging agent of blood vessels, which can quickly dilate our blood vessels. Therefore, it can protect our heart and blood vessels. The vertical rhythm machine uses mechanical force to push the human body upwards, and when the mechanical force stops, the human body naturally falls under the action of gravity, so as to achieve up-and-down rhythm, safely stimulate every part of the body, and achieve the effect of rehabilitating cardiovascular disease patients.

[0003] After retrieval, CN112402175A discloses a rhythmic wheelchair for cardiovascular disease rehabilitation. By driving the coordinated movement of a disc, a gear and a toothed rod through the rotation of a motor, the push plate can make a reciprocating lifting movement, thereby driving the seat and footrest on the wheelchair to move up and down at the same time, achieving the effect of vertical rhythm. The structure is simple and easy to use, and can be used to reduce the harm and recurrence of cardiovascular diseases.

[0004] During the rhythm process of this rhythmic wheelchair, there is no mechanism for fixing and limiting the legs and feet. In this way, when performing vertical up-and-down rhythm, the feet and legs will follow the up-and-down rhythm, resulting in bumpy displacement. Such long-term rhythm will cause the feet and legs to collide and cause pain. At the same time, due to the lack of a limiting effect, it will be very difficult for the feet and legs to move up and down following the rhythm, thus weakening the rhythm effect.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present utility model is:

[0007] A rhythmic wheelchair for cardiovascular disease rehabilitation, including a wheelchair;

[0008] A rhythmic device arranged in the wheelchair, a leg fixing mechanism is arranged on one side of the wheelchair, a foot limiting mechanism is arranged below the leg fixing mechanism, and the leg fixing mechanism includes a connecting plate fixedly connected to the outer wall of the rhythmic device:

[0009] A limiting chute is formed on the outer wall of the connecting plate. A limiting slider is slidably connected to the inner wall of the limiting chute. One end of the limiting slider away from the limiting chute is fixedly connected to a lower clamping plate. One end of the lower clamping plate is rotatably connected to a rotating shaft.

A positioning hole is formed in the outer wall of the inserting plate. A limiting block is fixedly connected to one side outer wall of the lower clamping plate. A sliding hole is formed in the outer wall of the limiting block. A positioning rod is slidably connected to the inner wall of the sliding hole. One end of the positioning rod is fixedly connected to a pulling plate. A first spring is fixedly connected to one end of the pulling plate close to the limiting block. The other end of the first spring away from the pulling plate is fixedly connected to the outer wall of the limiting block.

[0010] As a preferred embodiment of the present invention, the foot limiting mechanism includes a placing plate fixedly connected to the outer wall of the connecting plate. A placing groove is formed at the top end of the placing plate. A limiting cover is fixedly connected to the top end of the placing plate. A fixing block is fixedly connected to the top inner wall of the limiting cover. A chute is formed at the bottom end of the fixing block. A second spring is fixedly connected to the inner wall of the chute. A sliding column is fixedly connected to the other end of the second spring away from the inner wall of the chute. The outer wall of the sliding column is slidably connected to the inner wall of the chute. The other end of the sliding column away from the second spring is fixedly connected to a limiting clamping plate. A buffer block is fixedly connected to the bottom end of the limiting clamping plate.

[0011] As a preferred embodiment of the present invention, the number of the positioning holes is several. The positioning holes are evenly and equidistantly distributed on the outer wall of the inserting plate. The inner wall of the positioning hole is fitted with the outer wall of the positioning rod.

[0012] As a preferred embodiment of the present invention, the inserting plate is made of ductile plastic. A through hole is formed in the outer wall of the limiting block. The outer wall of the inserting plate is slidably connected to the inner wall of the through hole and is fitted with the outer wall of the inserting plate.

[0013] As a preferred embodiment of the present invention, the number of the limiting sliders is two. The limiting sliders are symmetrically distributed on the outer wall of the lower clamping plate in an up-and-down structure and are fitted with the inner wall of the limiting chute.

[0014] As a preferred embodiment of the present invention, the number of the sliding columns is two. The sliding columns are symmetrically distributed on the top end of the limiting clamping plate in a left-and-right structure. The inner wall of the chute formed at the bottom end of the fixing block is fitted with the outer wall of the sliding column.

[0015] As a preferred embodiment of the present invention, the buffer block is made of rubber material.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] In this utility model, first, pull the pull plate to drive the positioning rod to move outward. At the same time, when the pull plate moves, it drives the first spring to stretch. At this time, the positioning rod will be disengaged from the limiting engagement with the inner wall of the positioning hole. Subsequently, the upper clamping plate can be toggled outward. Through the rotational connection between the rotating shaft and the lower clamping plate, it can rotate. When the upper clamping plate rotates, it can drive the insertion plate to rotate and move outward. When the insertion plate rotates outward, it will be squeezed by the inner wall of the through groove opened on the outer wall of the lower clamping plate and then deformed until the entire insertion plate completely disengages from the inner wall of the through groove. In this way, the upper clamping plate can be separated from the lower clamping plate. After that, the patient can place the leg in the lower clamping plate, and then toggle the upper clamping plate to drive the insertion plate to pass through the through groove and insert into the limiting block. Adjust the depth of the insertion plate inserted into the limiting block according to the size of the patient's leg. After adjustment, release the pull plate, and the first spring's resilience force pulls the positioning rod to insert into the positioning hole to complete the positioning function. When the top of the placement plate performs rhythmic movements, it will drive the leg and the lower clamping plate to move up and down through the sliding connection between the limiting slider and the limiting chute, so as to maximally keep the rhythmic rhythm of the leg and the rhythmic device equal, improve the rhythmic effect, and prevent the foot and leg from having bumpy displacement limits.

[0018] In this utility model, before placing the leg in the lower clamping plate, insert the foot into the limiting cover and then place it on the placement groove. During the insertion process, the instep will contact and squeeze the buffer block. The squeezed buffer block will drive the limiting clamping plate and the sliding column to move upward. When the sliding column moves upward, it will squeeze and compress the second spring until the foot is completely inserted. Then, the resilience force of the second spring will push the limiting clamping plate in the reverse direction to wrap and cover the instep. At the same time, the buffer block will closely adhere to the instep. In this way, the foot can be limited, ensuring that the foot can follow the rhythmic rhythm during rhythmic movements, thus ensuring that the foot and leg synchronously follow the rhythmic rhythm and improving the rhythmic effect.

Specific implementation mode

[0026] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0027] As Figures 1 to 4 shown, a rhythm wheelchair for cardiovascular disease rehabilitation includes a wheelchair 1, a rhythm device 2 arranged in the wheelchair 1, a leg fixing mechanism 31 arranged on one side of the wheelchair 1, and a foot limiting mechanism 32 arranged below the leg fixing mechanism 31. The leg fixing mechanism 31 includes a connecting plate 3112 fixedly connected to the outer wall of the rhythm device 2. A limit chute 311 is provided on the outer wall of the connecting plate 3112. A limit slider 312 is slidably connected to the inner wall of the limit chute 311. One end of the limit slider 312 away from the limit chute 311 is fixedly connected to a lower splint 313. One end of the lower splint 313 is rotatably connected to a rotating shaft 314. An upper splint 315 is fixedly connected to the outer wall of the rotating shaft 314. An inserting plate 316 is fixedly connected to the outer wall of the upper splint 315. A positioning hole 317 is provided on the outer wall of the inserting plate 316. A limit block 318 is fixedly connected to one side outer wall of the lower splint 313. A sliding hole is provided on the outer wall of the limit block 318. A positioning rod 319 is slidably connected to the inner wall of the sliding hole. One end of the positioning rod 319 is fixedly connected to a pulling plate 3111. One end of the pulling plate 3111 close to the limit block 318 is fixedly connected to a first spring 3110. One end of the first spring 3110 away from the pulling plate 3111 is fixedly connected to the outer wall of the limit block 318.

[0028] Furthermore, the number of the positioning holes 317 is several, and the positioning holes 317 are evenly and equidistantly distributed on the outer wall of the inserting plate 316. The inner wall of the positioning hole 317 is fitted and matched with the outer wall of the positioning rod 319. In this way, the adjustment effect can be carried out according to the size of the patient's leg, so as to be applicable to people with different body postures, thereby improving the applicability of the wheelchair 1. At the same time, the fitting and matching of the positioning hole 317 and the positioning rod 319 can ensure the stability after positioning.

[0029] Further, the material of the insertion plate 316 is ductile plastic. Through holes are formed in the outer wall of the limiting block 318, and the outer wall of the insertion plate 316 is slidably connected to the inner wall of the through holes and is fitted and adapted to the outer wall of the insertion plate 316. By setting the insertion plate 316 as a ductile material, it can be ensured that the insertion plate 316 can be deformed during the process of being moved and extruded, which is convenient for the disassembly operation of the insertion plate 316.

[0030] Furthermore, the number of the limiting sliders 312 is two. The limiting sliders 312 are symmetrically distributed up and down on the outer wall of the lower clamping plate 313 and are fitted and adapted to the inner wall of the limiting sliding groove 311. In this way, the upper and lower ends of the lower clamping plate 313 can be supported and slid synchronously, thereby improving the stability of the lower clamping plate 313 during the up and down movement following the rhythm.

[0031] The foot limiting mechanism 32 includes a placement plate 327 fixedly connected to the outer wall of the connecting plate 3112. A placement groove 328 is formed at the top of the placement plate 327. A limiting cover 321 is fixedly connected to the top of the placement plate 327. A fixed block 322 is fixedly connected to the top inner wall of the limiting cover 321. A chute is formed at the bottom of the fixed block 322. A second spring 323 is fixedly connected to the inner wall of the chute. One end of the second spring 323 away from the inner wall of the chute is fixedly connected to a sliding column 324. The outer wall of the sliding column 324 is slidably connected to the inner wall of the chute. One end of the sliding column 324 away from the second spring 323 is fixedly connected to a limiting clamping plate 325. A buffer block 326 is fixedly connected to the bottom of the limiting clamping plate 325.

[0032] Further, the number of the sliding columns 324 is two. The sliding columns 324 are symmetrically distributed left and right at the top of the limiting clamping plate 325. The inner wall of the chute formed at the bottom of the fixed block 322 is fitted and adapted to the outer wall of the sliding column 324, so as to ensure that force is applied to the left and right sides of the limiting clamping plate 325 synchronously, thereby ensuring that the limiting clamping plate 325 can more closely clamp and limit the instep during the clamping and limiting process.

[0033] Furthermore, the material of the buffer block 326 is rubber material, so that it can be reversely fitted to the instep through the characteristics of rubber, thereby further improving the limiting stability of the foot.

[0034] The implementation principle of a rhythmic wheelchair for cardiovascular disease rehabilitation in this embodiment is as follows: First, pull the pull plate 3111 to drive the positioning rod 319 to move outward. At the same time, when the pull plate 3111 moves, it drives the first spring 3110 to stretch. At this time, the positioning rod 319 will be disengaged from the limiting engagement with the inner wall of the positioning hole 317. Then, the upper clamping plate 315 can be toggled outward and rotate through the rotational connection between the rotating shaft 314 and the lower clamping plate 313. When the upper clamping plate 315 rotates, it can drive the insertion plate 316 to rotate and move outward. When the insertion plate 316 rotates outward, it will be squeezed by the inner wall of the through groove formed on the outer wall of the lower clamping plate 313 and then deformed until the whole insertion plate 316 completely disengages from the inner wall of the through groove. In this way, the upper clamping plate 315 can be separated from the lower clamping plate 313. After that, the patient can place the leg in the lower clamping plate 313, and then toggle the upper clamping plate 315 to drive the insertion plate 316 to pass through the through groove and insert into the limiting block 318. Adjust the depth of the insertion plate 316 inserted into the limiting block 318 according to the size of the patient's leg. After adjustment, release the pull plate 3111, and the first spring 3110's resilience force pulls the positioning rod 319 to insert into the positioning hole 317 to complete the positioning function. When the top of the placement plate 327 performs rhythmic movement, it will drive the leg and the lower clamping plate 313 to move up and down through the sliding connection between the limiting slider 312 and the limiting chute 311, so as to keep the rhythm of the leg and the rhythmic device 2 equal to the greatest extent, improve the rhythmic effect, and prevent the feet and legs from jolting and displacement limits.

[0035] Before placing the leg in the lower clamping plate 313, insert the foot into the limiting cover 321 and then place it on the placement groove 328. During the insertion process, the instep will contact the buffer block 326 and squeeze it. The squeezed buffer block 326 will drive the limiting clamping plate 325 and the sliding column 324 to move upward. When the sliding column 324 moves upward, it will squeeze and compress the second spring 323 until the foot is completely inserted. Then, the resilience force of the second spring 323 will push the limiting clamping plate 325 to wrap and cover the instep in the reverse direction. At the same time, the buffer block 326 will closely adhere to the instep, so as to limit the foot and ensure that the foot can follow the rhythmic rhythm during the rhythm, so as to ensure that the feet and legs follow the rhythmic rhythm synchronously and improve the rhythmic effect.
