Description

Technical Field

[0001] The invention belongs to the technical field of vibration-type fitness, and in particular relates to a wheelchair rhythmic device for fitness for disabled people. Background Art

[0002] The rhythmic platform is a device used to assist patients who are unable to move on their own to perform assisted exercise. It mainly simulates the vibrations caused to the body during exercise through frequency vibration, thereby affecting the body's musculoskeletal nervous system, as well as endocrine and other physiological systems, and speeding up recovery through proper exercise.

[0003] A search of CN204033642U discloses a wheelchair rhythmic device, in which two supporting wings are extended from both sides of a supporting cover seat, and the two supporting covers are connected to the vibration device by a plurality of connecting parts so as to vibrate. Therefore, a disabled person with limited mobility can sit on the two supporting covers in a wheelchair, and then start the vibration device. The supporting wings will transmit power to the wheelchair, thereby causing the disabled person to vibrate, thereby achieving the effect of rhythmic movement and fitness.

[0004] However, there is no mechanism on the supporting wing in the rhythmic device that can limit and fix the wheels of the wheelchair. In this way, when the wheelchair moves on it for rhythmic exercise, the wheelchair will follow the vibration and thus move. In this way, the wheelchair will gradually leave the top of the supporting wing, thereby failing to achieve the purpose of rhythmic exercise.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] In order to solve the above technical problem that there is no mechanism on the supporting wing in the rhythmic device that can limit and fix the wheelchair wheels, so when the wheelchair moves on it for rhythmic exercise, the wheelchair will follow the vibration and thus produce displacement, so that the wheelchair will gradually separate from the top of the supporting wing, thereby failing to achieve the purpose of rhythmic exercise. The basic concept of the technical solution adopted by the present invention is:

The sliding rod is rotatably connected to the extrusion roller on the outer wall away from one end of the sliding sleeve. The outer wall of the rhythmic device is provided with a storage groove, and a supporting plate is provided on the inner wall of the storage groove. A groove is provided on the outer wall of the supporting plate. A rotating groove is provided on the inner wall of the groove. The inner wall of the rotating groove is rotatably connected to the inner wall of the rotating groove through a bearing.

The outer wall of the rotating shaft is fixedly connected to the supporting plate, and a receiving inclined surface is provided on the outer wall of one end of the supporting plate.

[0010] As a preferred embodiment of the present invention, the storage mechanism includes a gear fixedly connected to one end of the threaded rod, the outer wall of the sliding rod is fixedly connected to a connecting rod, the bottom of the outer wall of the connecting rod at one end away from the sliding rod is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a connecting block, the outer walls of the connecting block are respectively fixedly connected to a first rack and a second rack, the inner wall of the storage groove opened on the outer wall of the rhythmic device is opened to a limiting slide groove, the inner wall of the limiting slide groove is slidably connected to a limiting slider, and the limiting slider is fixedly connected to the outer wall of the supporting plate at one end away from the limiting slide groove.

[0011] As a preferred embodiment of the present invention, the supporting moving mechanism includes a slide cylinder, a through hole is opened at the bottom end of the rhythmic device, the outer wall of the slide cylinder is fixedly connected to the inner wall of the through hole, the inner wall of the slide cylinder is slidably connected to a force column, the bottom end of the force column is fixedly connected to a receiving plate, the top end of the receiving plate is fixedly connected to a spring, one end of the spring away from the receiving plate is fixedly connected to the bottom end of the slide cylinder, and the end of the receiving plate away from the spring is fixedly connected to a roller.

[0012] As a preferred embodiment of the present invention, there are two support plates, and the support plates are symmetrically distributed on the left and right sides of the rhythmic device.

[0013] As a preferred embodiment of the present invention, an inclined groove is provided at the bottom end of the support plate, and the extrusion roller is rollingly arranged on the inner wall of the inclined groove.

[0014] As a preferred embodiment of the present invention, the inner wall of the storage groove opened on the outer wall of the rhythmic device fits in close contact with the outer wall of the supporting plate, and the inner wall of the rotating groove opened on the inner wall of the supporting plate fits in close contact with the outer wall of the rotating shaft.

[0015] As a preferred embodiment of the present invention, a through-slide groove is provided on the outer wall of the rhythmic device, the outer wall of the connecting rod is slidably connected to the inner wall of the through-slide groove, and the inner wall of the through-slide groove fits snugly with the outer wall of the connecting rod.

[0016] As a preferred embodiment of the present invention, the number of the rollers is four, and the rollers form a group of two and are distributed on the left and right sides of the bottom end of the rhythmic device in a left-right symmetrical structure.

[0017] As a preferred embodiment of the present invention, the inner wall of the slide cylinder fits snugly with the outer wall of the load-bearing column.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the motion stops, the motor is started to reverse and drive the threaded block to move forward, thereby driving the extrusion roller to squeeze the support plate until it is flush with the top surface of the support plate, and then the wheelchair can be pushed away.

[0020] According to the present invention, when the two supporting plates need to be stored, the electric telescopic rod can be started, and the output end of the electric telescopic rod will drive the first rack and the second rack to move downward and upward, so that the first rack and the second rack are meshed, and then the threaded rod drives the gear to rotate counterclockwise, which can drive the first rack and the second rack to move closer to the middle. When the first rack and the second rack are moving, they will drive the connecting rod to move closer to the middle. When the connecting rod moves, it can drive the left and right supporting plates to move closer to the middle. During the movement, the supporting plate will drive the limiting slider to move on the inner wall of the limiting slide groove, so as to ensure the stability of the supporting plate during the movement. In this way, the two supporting plates can be stored inside the rhythmic equipment, thereby reducing the space occupied by the rhythmic equipment.

[0021] When the support plate is in a retracted position, the support plate will squeeze the load-bearing column, and the squeezed load-bearing column will move downward on the inner wall of the slide tube. When the load-bearing column moves downward, the support plate will be driven to move downward, thereby the support plate will drive the roller to move downward. At the same time, in the process of the support plate moving downward, the spring will be stretched until the bottom end of the roller contacts the ground, and then the entire rhythmic device is supported, so that the supporting legs are away from the ground, and only the rollers are in contact with the ground for support. In this way, when the rhythmic device needs to be moved, it only needs to be pushed to move. After moving to the appropriate position, the support plates on both sides are controlled to move to both sides. At this time, the load-bearing column is no longer squeezed by it, and the rollers can be driven to move upward by the rebound of the spring, so that the supporting legs are in contact with the ground for support, thereby performing a limit support function on the rhythmic device.

[0022] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

A storage groove is provided on the outer wall of the rhythmic device 1, and a supporting plate 318 is provided on the inner wall of the storing groove. A groove is provided on the outer wall of the supporting plate 318, and a rotating groove 319 is provided on the inner wall of the groove. The end of the sliding rod 316 away from the sliding sleeve 315 is rotatably connected to the inner wall of the rotating groove 319 through a bearing clamping connection, and a rotating groove is provided above the inner wall of the groove provided on the outer wall of the supporting plate 318. The inner wall of the rotating groove is rotatably connected to a rotating shaft 3110, and a supporting plate 3111 is fixedly connected to the outer wall of the rotating shaft 3110, and a receiving inclined surface 3112 is provided on the outer wall of one end of the supporting plate 3111.

[0036] Furthermore, there are two support plates 318, which are symmetrically distributed on the left and right sides of the rhythmic equipment 1, so that the left and right wheels of the wheelchair can be supported, so that the disabled person can directly sit on the wheelchair to complete the purpose of rhythmic fitness.

[0037] Furthermore, an inclined groove is provided at the bottom end of the support plate 3111, and an extrusion roller 317 is rotatably arranged on the inner wall of the inclined groove. Through the inclined groove provided at the bottom end of the support plate 3111, the extrusion roller 317 squeezes and supports the support plate 3111 during the process of rolling left and right, so that the support plate 3111 can be adjusted between an inclined state and a parallel state, thereby limiting the wheels on the left and right sides of the wheelchair and preventing the wheelchair from shifting during rhythmic fitness.

[0038] Embodiment 2:

[0039] The difference between the above embodiment and this embodiment is that: Figures 1 to 8 As shown, a wheelchair rhythmic device for fitness for disabled people is provided. The storage mechanism 32 includes a gear 321 fixedly connected to one end of a threaded rod 313, a connecting rod 326 is fixedly connected to the outer wall of the sliding rod 316, an electric telescopic rod 325 is fixedly connected to the bottom of the outer wall of the end of the connecting rod 326 away from the sliding rod 316, and a connecting block 324 is fixedly connected to the output end of the electric telescopic rod 325. The outer wall of the connecting block 324 is respectively fixedly connected to the first rack 322 and the second rack 323, and a storage groove provided on the outer wall of the rhythmic device 1 is provided with a limiting slide groove 327 on the inner wall, and a limiting slider 328 is slidably connected to the inner wall of the limiting slide groove 327, and the limiting slider 328 is fixedly connected to the outer wall of the supporting plate 318 at one end away from the limiting slide groove 327.

[0040] Furthermore, the inner wall of the storage groove opened on the outer wall of the rhythm device 1 fits snugly with the outer wall of the support plate 318, and the inner wall of the rotating groove opened on the inner wall of the support plate 318 fits snugly with the outer wall of the rotating shaft 3110, thereby ensuring the tightness between the rotating shaft 3110 and the inner wall of the rotating groove during rotation, thereby ensuring stability during rotation.

[0041] Furthermore, a through-slide groove is provided on the outer wall of the rhythm device 1, and the outer wall of the connecting rod 326 is slidably connected to the inner wall of the through-slide groove, and the inner wall of the through-slide groove fits closely with the outer wall of the connecting rod 326, thereby ensuring that the connecting rod 326 can move left and right while maintaining the stability of the connecting rod 326 during the left and right movement.

[0042] Embodiment 3:

[0043] The difference between the above embodiment and this embodiment is that: Figures 1 to 8As shown, a wheelchair rhythmic device for fitness for disabled people, the supporting moving mechanism 33 includes a slide cylinder 331, a through hole is opened at the bottom end of the rhythmic device 1, the outer wall of the slide cylinder 331 is fixedly connected to the inner wall of the through hole, the inner wall of the slide cylinder 331 is slidably connected to a force column 332, the bottom end of the force column 332 is fixedly connected to a receiving plate 334, the top end of the receiving plate 334 is fixedly connected to a spring 333, the end of the spring 333 away from the receiving plate 334 is fixedly connected to the bottom end of the slide cylinder 331, and the end of the receiving plate 334 away from the spring 333 is fixedly connected to a roller 335.

[0044] Furthermore, there are four rollers 335, which are grouped together into two and are symmetrically arranged on the left and right sides of the bottom of the rhythmic device 1. Thus, the four rollers 335 can provide mobile support for the entire rhythmic device 1, making it more convenient for users to move the rhythmic device 1.

[0045] Furthermore, the inner wall of the slide cylinder 331 fits snugly with the outer wall of the load-bearing column 332 , thereby ensuring the tightness between the outer wall of the load-bearing column 332 and the inner wall of the slide cylinder 331 , thereby ensuring stability in the state of mobile support.

[0046] The implementation principle of the wheelchair rhythmic device for fitness of the disabled in this embodiment is as follows: after the support plate 318 is extended, the patient and the wheelchair can be pushed onto the support plate 318 through the receiving inclined surface 3112. After the wheelchair is pushed, the motor 312 can be started, and its output line moves. When the slide bar 316 moves, it will drive the extrusion roller 317 to the rear end and drive the threaded rod 313 to rotate. When the threaded rod 313 rotates, it can drive the sliding sleeve 315 and the slide bar 316 to move backward. When the extrusion roller 317 moves backward, it will gradually release the contact support with the inclined groove at the bottom of the support plate 318, and then the support plate 3111 will be supported by gravity. By rotating the rotating shaft 3110 downward, the support plate 3111 will be tilted with the left side lower and the right side higher, so that the wheels of the wheelchair will abut between the supporting plate 318 and the supporting plate 3111. At the same time, since the supporting plate 3111 is in a tilted state, the wheelchair will be at the lowest point of the supporting plate 3111 due to gravity, thereby completing the support and limiting effect on the wheelchair to prevent the wheelchair from shifting during the rhythmic movement. When the rhythm is stopped, the start motor 312 is reversed to drive the threaded block 314 to move forward, thereby driving the extrusion roller 317 to squeeze the support plate 3111 until it is flush with the top surface of the supporting plate 318, and then the wheelchair can be pushed away.

[0047] When the two supporting plates 318 need to be stored, the electric telescopic rod 325 can be started, and its output end will drive the first rack 322 and the second rack 323 to move downward and upward, so that the first rack 322, the second rack 323 are meshed with the gear 321, and then the threaded rod 313 drives the gear 321 to rotate counterclockwise, which can drive the first rack 322 and the second rack 323 to move closer to the middle. When the first rack 322 and the second rack 323 move, they will drive the connecting rod 326 to move closer to the middle. When the connecting rod 326 moves, it can drive the left and right supporting plates 318 to move closer to the middle. During the movement, the supporting plate 318 will drive the limiting slider 328 to move on the inner wall of the limiting slide groove 327, so as to ensure the stability of the supporting plate 318 during the movement. In this way, the two supporting plates 318 can be stored inside the rhythmic device 1, thereby reducing the space occupied by the rhythmic device 1.

[0048] When the rhythmic device 1 is in the storage state, the supporting plate 318 will squeeze the load-bearing column 332, and the squeezed load-bearing column 332 will move downward on the inner wall of the slide cylinder 331. When the load-bearing column 332 moves downward, it will drive the receiving plate 334 to move downward, so that the receiving plate 334 will drive the roller 335 to move downward. At the same time, during the downward movement of the receiving plate 334, the spring 333 will be stretched until the bottom end of the roller 335 contacts the ground, and then the entire rhythmic device 1 is supported, so that the supporting leg 2 is away from the ground, and only the roller 335 contacts the ground for support. In this way, when the rhythmic device 1 needs to be moved, it only needs to be pushed to move. After moving to the appropriate position, the supporting plates 318 on both sides are controlled to move to both sides. At this time, the load-bearing column 332 is no longer squeezed by it, and the roller 335 can be driven to move upward through the rebound of the spring 333, so that the supporting leg 2 contacts the ground for support, thereby performing a limit support function on the rhythmic device 1.
