Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training, in particular to a rehabilitation training device. Background Technique

[0002] Patients in the department of neurology will have symptoms of limb insensitivity due to nervous system problems. During the rehabilitation treatment process, in order to improve the rehabilitation speed of neurology patients, a rehabilitation training device is used to enable patients to carry out rehabilitation exercises, so that patients can recover better.

[0003] Comparing the authorized publication number CN217745526U, a neurology rehabilitation training device, the patient places the foot on the pedal and fixes it through a fixing belt, and then exercises by stepping on the pedal forcefully to move the pedal and drive the guide seat to squeeze the compression spring, which is convenient for exercise.

[0004] For the above-mentioned neurology rehabilitation training device, through the patient's stepping on the pedal and using the extrusion of the spring, the training of the legs is realized. Although the operation is relatively simple, after the spring is squeezed, the spring is deformed by force to form an elastic force. When the pedal is stepped on in place and the stepping force on the pedal is released, the pedal and the patient's legs will be pushed to move in the reverse direction under the reverse elastic force of the spring. Due to the insufficient strength of the patient's own legs, after a single step on the pedal, it is easy to be exhausted. Therefore, under the reverse elastic force of the spring and the insufficient control force of the patient himself, the patient will be subjected to a relatively strong reverse pushing impact force, which is likely to cause the patient to feel discomfort or pain and increase the risk of injury.

[0005] Therefore, there is an urgent need for a rehabilitation training device to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a rehabilitation training device to solve the problem that the patient will be subjected to a relatively strong reverse pushing impact force proposed in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A rehabilitation training device includes a bottom plate and a base arranged on the bottom plate. The base is provided with an installation hole, and two symmetrically arranged installation rods are fixedly connected in the installation hole. A sliding plate is slidably connected to the two installation rods. The opposite sides of the sliding plate are connected with a pedal through a fixed rod. Compression springs are sleeved on the side walls of the two installation rods. A buffer mechanism is further arranged on the base and is used for buffering the reverse impact force of the two pedals.

[0008] The buffer mechanism includes a buffer tube fixedly connected to the base. A buffer rod is slidably connected to the buffer tube. One end of the buffer rod is connected to the sliding plate, and the other end of the buffer rod is fixedly connected to a buffer plate. The end of the buffer tube away from the pedal penetrates through the base and is fixedly connected to an air outlet pipe and an air inlet pipe. A one-way valve is provided in the air outlet pipe, and the conduction direction of the one-way valve is from the inside of the buffer tube to the outside. A control mechanism for controlling the intake air volume is provided on the air inlet pipe.

[0009] The control mechanism includes a first control plate fixedly connected to the air inlet pipe. A second control plate is connected to the side of the first control plate close to the buffer tube through a rotating shaft. Control holes are provided on both the first control plate and the second control plate. A driving mechanism for driving the second control plate is provided on the air inlet pipe.

[0010] The driving mechanism includes two symmetrically arranged driving rods fixedly connected to the inner wall of the air inlet pipe. Driving plates are slidably connected to both driving rods. A rack is fixedly connected between the two driving plates. A gear is fixedly connected to the side wall of the rotating shaft, and the gear is meshed with the rack. A pushing assembly for pushing the rack is provided on the air inlet pipe.

[0011] The pushing assembly includes two symmetrically arranged T-shaped rods fixedly connected to the side wall of the air inlet pipe. An operation plate is slidably connected between the two T-shaped rods. A pushing plate is fixedly connected to the side of the operation plate close to the air inlet pipe.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1 - 4 , a rehabilitation training device shown in the figure, including a bottom plate 101 and a base 102 provided on the bottom plate 101. The base 102 is provided with a mounting hole 103. Two symmetrically arranged mounting rods 104 are fixedly connected in the mounting hole 103. A sliding plate 105 is slidably connected to the two mounting rods 104. Pedals 106 are connected to opposite sides of the sliding plate 105 through fixed rods. Compression springs 107 are sleeved on the side walls of the two mounting rods 104. It further includes a buffer mechanism provided on the base 102 and used for buffering the reverse impact force of the two pedals 106;

[0023] The buffer mechanism includes a buffer tube 201 fixedly connected to the base 102. A buffer rod 202 is slidably connected to the buffer tube 201. One end of the buffer rod 202 is connected to the sliding plate 105, and the other end of the buffer rod 202 is fixedly connected to a buffer plate 203. The end of the buffer tube 201 away from the pedal 106 penetrates through the base 102 and is fixedly connected to an air outlet pipe 204 and an air inlet pipe 205. A one-way valve 206 is provided in the air outlet pipe 204, and the conduction direction of the one-way valve 206 is from the inside to the outside of the buffer tube 201. The air inlet pipe 205 is provided with a control mechanism for controlling the air intake volume;

[0024] It should be noted here that: through the setting of the buffer mechanism, under the action of the control mechanism, the flow rate of external gas entering the buffer tube 201 is small, thereby providing resistance for the sliding of the buffer plate 203 in the buffer tube 201, and further providing resistance for the sliding of the sliding plate 105, thereby reducing the reverse impact force of the compression spring 107 on the pedal 106, reducing the reset speed of the pedal 106, avoiding discomfort or pain caused by excessive impact force to the patient, reducing the risk of injury to the patient during rehabilitation training, and further improving the safety of the rehabilitation training device during use.

[0025] It is worth noting that: for the specific structure and use steps of the rehabilitation training device, please refer to the authorized publication number CN217745526U, a neurological rehabilitation training device, which will not be elaborated here.

[0026] Please refer to Figure 3 and Figure 4 As shown in the figure, the control mechanism includes a first control board 301 fixedly connected to the air inlet pipe 205. A second control board 302 is connected to the side of the first control board 301 close to the buffer tube 201 through a rotating shaft 304. Control holes 303 are provided on both the first control board 301 and the second control board 302. The air inlet pipe 205 is provided with a driving mechanism for driving the second control board 302;

[0027] It should be noted here that: through the setting of the control mechanism, the flow rate of external gas entering the buffer tube 201 is small, thereby providing resistance for the sliding of the buffer plate 203 in the buffer tube 201.

[0028] Working principle: When a neurological patient undergoes rehabilitation training, first fix the bottom plate 101 to the hospital bed through the clamping assembly, then place both feet on the pedal 106, and step on the pedal 106 to move it and drive the sliding plate 105 to compress the compression spring 107. Thus, under the elastic resistance of the compression spring 107, the patient's legs are exercised;

[0029] When the patient compresses the compression spring 107 through the pedal 106, it will drive the buffer plate 203 at one end of the buffer rod 202 to slide in the buffer tube 201. Thus, under the extrusion of the buffer plate 203, the gas in the buffer tube 201 can flow out through both the air outlet pipe 204 and the air inlet pipe 205, so that no additional resistance will be generated to the movement of the pedal 106. When the patient finishes stepping on the pedal 106 once and retracts the legs backward, the driving force on the pedal 106 will be reduced. At this time, under the reverse elastic action of the compression spring 107, it will push the sliding plate 105 to move closer to the patient, further driving the buffer plate 203 at one end of the buffer rod 202 to slide reversely in the buffer tube 201. Thus, under the action of the air pressure difference and the one-way blocking of the one-way valve 206, only the external gas can enter from the air inlet pipe 205. And through the staggered arrangement of the first control plate 301 and the second control plate 302 in the air inlet pipe 205, the flow rate of the external gas entering the buffer tube 201 is small, which provides resistance for the sliding of the buffer plate 203 in the buffer tube 201, and further provides resistance for the sliding of the sliding plate 105, thereby reducing the reverse impact force of the compression spring 107 on the pedal 106, reducing the reset speed of the pedal 106, avoiding discomfort or pain caused by excessive impact force to the patient, reducing the risk of injury to the patient during rehabilitation training, and further improving the safety of the rehabilitation training device during use;

[0030] And under the action of the driving mechanism, it can be adjusted so that the control holes 303 on the second control plate 302 coincide or stagger with the control holes 303 on the first control plate 301, thereby changing the ventilation size of the control holes 303, further changing the intake air volume entering the buffer tube 201, thereby changing the resistance to the reverse sliding of the pedal 106, increasing the reverse sliding speed of the pedal 106, so as to facilitate adjusting the reverse movement speed of the pedal 106 according to the patient's own situation, further increasing the movement frequency of the pedal 106, reducing the time of one training, and increasing the number of trainings per unit time.

[0031] Embodiment 2

[0032] Please refer to Figure 3 and Figure 4 This embodiment further illustrates Embodiment 1. The driving mechanism shown in the figure includes two symmetrically arranged driving rods 401 fixedly connected to the inner wall of the air inlet pipe 205. Driving plates 402 are slidably connected to both driving rods 401. A rack 403 is fixedly connected between the two driving plates 402. A gear 404 is fixedly connected to the side wall of the rotating shaft 304. The gear 404 is meshed with the rack 403. A pushing component for pushing the rack 403 is provided on the air inlet pipe 205;

[0033] It should be noted here that: through the setting of the driving mechanism, under the action of the pushing component, the rack 403 will be driven to move. Thus, under the meshing transmission action between the rack 403 and the gear 404, the second control plate 302 will be driven to rotate. During the rotation of the second control plate 302, the control holes 303 on the second control plate 302 will coincide or misalign with the control holes 303 on the first control plate 301, thereby changing the ventilation size of the control holes 303 and further changing the intake air volume entering the buffer tube 201.

[0034] Please refer to Figure 3 and Figure 4 , in the figure, the pushing component includes two symmetrically arranged T-shaped rods 501 fixedly connected to the side wall of the intake pipe 205. A operating plate 502 is slidably connected between the two T-shaped rods 501. A pushing plate 503 is fixedly connected to the side of the operating plate 502 close to the intake pipe 205. The other end of the pushing plate 503 penetrates through the intake pipe 205 and is connected to the rack 403. A moving component for moving the pushing plate 503 is provided on the operating plate 502;

[0035] It should be noted here that: through the setting of the pushing component, under the action of the moving component, the pushing plate 503 will be driven to move, thereby further driving the rack 403 to move.

[0036] Please refer to Figure 3 and Figure 4 , in the figure, the moving component includes a connecting plate 601 fixedly connected to one side of the operating plate 502. A threaded rod 602 is threadedly connected to the connecting plate 601. One end of the threaded rod 602 is connected to the intake pipe 205, and the other end of the threaded rod 602 is fixedly connected with a crank 603;

[0037] It should be noted here that: through the setting of the moving component, during the rotation of the crank 603, the threaded rod 602 will be driven to rotate. Under the threaded meshing transmission action between the threaded rod 602 and the connecting plate 601 and the guiding action of the two T-shaped rods 501, the pushing plate 503 on one side of the operating plate 502 will be driven to move.
