Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training chair technology, and in particular to a multifunctional adjustable rehabilitation training chair. Background Technology

[0002] In today's society, with a booming economy and significantly improved living standards, the pace of life is also accelerating. Under this fast-paced lifestyle, health and happiness have become the goals pursued by many. People are increasingly valuing their quality of life and eager to maintain good physical condition through exercise. However, many limiting factors hinder people's pursuit of health. Many are too busy with work and daily life to find time to go to gyms or other fitness facilities. These factors combined make it difficult for these people to get sufficient and effective exercise, which gradually affects their health. When health problems arise, especially injuries or functional degeneration of joints like the elbow, rehabilitation training becomes crucial. However, traditional rehabilitation methods are difficult to implement under limited exercise conditions. This is where the advantages of training tables and chairs become apparent. They provide a convenient and flexible rehabilitation training method, not overly restricted by time or location. Users can conduct rehabilitation training at home anytime, according to their own situation, greatly improving the accessibility and convenience of rehabilitation training.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: When performing elbow joint rehabilitation training, patients use a training chair to carry out related exercises. However, because the patient's elbow joint is already injured, it is very easy for the patient to lose strength during the training process, resulting in an inability to lift. However, the existing training chair device is not equipped with a stopping structure. Once the patient experiences the above situation, the training cannot be stopped in time. This not only affects the normal progress of rehabilitation training, but more seriously, it may cause greater damage to the patient's injured elbow joint.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the basic technical solution proposed by this utility model is as follows: a multifunctional adjustable rehabilitation training chair, including two support plates that are symmetrically distributed, a seat is installed in the middle of the two support plates, elbow joint training structures are provided on both sides of the seat, and a stop structure is provided on the top of the support plates and both sides of the seat.

[0006] The stopping structure includes two locking plates, two first slide rails and two second slide rails, and a fixing plate for fixing the first slide rails and the second slide rails. A first gear plate is slidably connected to the inner wall of the first slide rail, and a second gear plate is slidably connected to the inner wall of the second slide rail. A meshing gear is provided between the first gear plate and the second gear plate.

[0007] The beneficial effects of this utility model are:

[0008] The design of the elbow joint training and stopping structures significantly improves training safety. If the user experiences sudden loss of arm strength during training, they can activate the stopping structure by actively pressing the foot pedal. Under the precise control of the limiting plate, the foot pedal moves vertically downwards, compressing the return spring. Simultaneously, the extension block connected to the foot pedal moves downwards, driving the connected second gear plate downwards under the constraint of the second slide rail. The movement of the second gear plate causes the meshing gear to rotate synchronously. The rotation of the meshing gear further drives the first gear plate upwards. During the upward movement of the first gear plate, the locking plate fixed to it gradually approaches and eventually comes into close contact with the rotating disk. Because the locking plate uses a material and structure similar to brake pads, a strong frictional force is generated between the locking plate and the rotating disk when they contact each other, effectively stopping the rotating disk. The connected training components then stop operating, thus avoiding accidental injury caused by loss of arm strength and ensuring the safety and stability of the training process.

[0015] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0017] Example 1

[0018] Please see Figure 1 - Figure 4 As shown, this embodiment provides a multifunctional adjustable rehabilitation training chair, including two symmetrically distributed support plates 1, a seat 2 installed in the middle of the two support plates 1, elbow joint training structures 3 provided on both sides of the seat 2, and stop structures 4 provided on the top of the support plates 1 and both sides of the seat 2. The seat is equipped with anti-slip blocks and a safety belt. When training, the seat belt is first locked and fixed, and the protective blocks are located in the crotch area to reduce the possibility of the patient slipping on the seat 2. This structure and technology are common in the field and are relatively mature, so they will not be described in detail.

[0019] The stopping structure 4 includes two locking pieces 41, two first slide rails 42 and two second slide rails 43, and a fixing plate 44 for fixing the first slide rails 42 and the second slide rails 43. The inner wall of the first slide rail 42 is slidably connected to a first gear plate 45, and the inner wall of the second slide rail 43 is slidably connected to a second gear plate 46. A meshing gear 47 is provided between the first gear plate 45 and the second gear plate 46. The first slide rails 42 and the second slide rails 43 are used to limit the movement direction of the first gear plate 45 and the second gear plate 46, and the meshing gear 47 is meshed with the first gear plate 45 and the second gear plate 46 respectively.

[0020] This invention addresses the issue that patients undergoing elbow joint rehabilitation training using a training chair are prone to weakness and lack of support during training due to elbow injuries. Existing training chairs lack a stopping mechanism, making it impossible to stop training promptly, which not only affects the rehabilitation process but may also cause further damage to the injured elbow joint. Therefore, the design of the elbow joint training structure 3 and the stopping structure 4 significantly improves training safety. When the user experiences sudden weakness in their arm during training, they can activate the stopping structure 4 by actively pressing the foot pedal 49. Under the precise limitation of the limiting plate 492, the foot pedal 49 moves vertically downwards, compressing the return spring 491. Simultaneously, the extension block 48 connected to the foot pedal 49 moves downwards, thereby driving the extension block 48 to move downwards. The connected second gear plate 46 moves downward under the constraint of the second slide rail 43. The movement of the second gear plate 46 causes the meshing gear 47 to rotate synchronously. The rotation of the meshing gear 47 further drives the first gear plate 45 to move upward. During the upward movement of the first gear plate 45, the locking plate 41 fixed on it gradually approaches and finally comes into close contact with the rotating disk 363. Since the locking plate 41 adopts a material and structure design similar to a brake pad, when the locking plate 41 contacts the rotating disk 363, a strong frictional force is generated between the two, thereby effectively stopping the rotating disk 363. The training component connected to it then stops operating, thus avoiding accidental injury caused by loss of force and ensuring the safety and stability of the training process.

[0021] Example 2

[0022] like Figure 2 - Figure 4As shown, an extension block 48 is fixedly connected to the bottom of the second gear plate 46, a foot pedal 49 is fixedly connected to the front of the extension block 48, a return spring 491 is fixedly connected to the bottom of the foot pedal 49, and limiting plates 492 for limiting the movement of the foot pedal 49 are provided on both sides of the foot pedal 49. The return spring 491 is provided with a hydraulic buffer rod for reducing excessive deformation. The elbow joint training structure 3 includes a connecting block 31 installed on the top surface of the two support plates 1 and a rotating plate 32 rotatably connected to the inner wall of the connecting block 31, and an extension plate 33 installed on the outside of the two support plates 1. A large arm rest pillow 34 is installed on the top surface of the rotating plate 32. A sleeve 35 is installed above the extension plate 33. A shaft is rotatably connected inside the sleeve 35 through a bearing. One end of the shaft is fixedly connected to a first sprocket 36, and the other end of the shaft is fixedly connected to a crossbar 37. The outer wall of the crossbar 37 is provided with equidistantly distributed fixing holes, and a fixing frame 38 is slidably connected to the outside of the crossbar 37. The position of the forearm placement pillow can be adjusted by adjusting the position of the fixing frame 38, thus making it suitable for different patients. The fixing frame 38 is rotated on the inner wall of the fixing hole by a screw, thereby locking the fixing frame 38 to the outside of the crossbar 37. The forearm placement pillow is installed on the opposite side of the fixing frame 38. The forearm placement pillow is provided with two straps for fixing the arm. The outer side of the first sprocket 36 is engaged with a chain 361. The inner wall of the chain 361 is also engaged with a second sprocket 362. The end of the second sprocket 362 away from the shaft is fixedly connected to a rotating disk 363. Through the transmission of the sprocket and the chain, the rotation of the shaft will eventually drive the rotating disk 363 to rotate during training. The side of the crossbar 37 away from the shaft is fixedly connected with a guide plate. The outside of the guide plate is fixedly connected with a placement rod. A counterweight is sleeved on the outside of the placement rod. The outside of the placement rod is provided with threads. The counterweight is locked by rotating the nut to reduce the risk of the counterweight shifting.

[0023] It is worth noting that the limiting plates 492 are set on both sides of the foot pedal 49, which can effectively limit the range of movement of the foot pedal 49 and prevent the foot pedal 49 from moving excessively or deviating due to accidental situations such as excessive force or loss of balance by the patient. This avoids the risk of injury to the patient due to loss of control of the foot pedal 49 and provides a safer training environment for the patient. Different patients have different rehabilitation stages and physical conditions, and their training intensity needs are also different. By placing different numbers of counterweights on the placement rod and locking them with nuts, the resistance of the training can be easily adjusted. For patients in the early stage of rehabilitation, fewer counterweights can be selected to train with less resistance and gradually restore the function of the elbow joint. As rehabilitation progresses, the number of counterweights can be gradually increased to increase the training intensity and promote further recovery of elbow joint function.

[0024] Work steps;

[0025] First, before rehabilitation training, the patient sits on seat 2 and adjusts the position of the fixed frame 38 on the crossbar 37 according to their arm length to ensure the forearm support pillow is at a suitable height. Then, the fixed frame 38 is locked with a screw. Next, depending on the rehabilitation stage and physical condition, an appropriate amount of counterweight is placed on the support bar and locked with a nut. Then, the upper arm is placed on the upper arm support pillow 34, and the forearm on the forearm support pillow, secured with straps. At the start of training, the patient only needs to control the reciprocating bending motion of the forearm. This rotates the shaft, causing the first sprocket 36 to rotate. Under the transmission of the chain 361, the second sprocket 362 rotates accordingly, ultimately driving the rotating disk 363 to rotate. If the patient suddenly experiences weakness in their arm during training, they can actively step on the foot pedal 49. Under the limiting action of the limiting plate 492, the patient can achieve the desired effect. The foot pedal 49 moves vertically downwards, simultaneously compressing the return spring 491. During this process, the extension block 48 and the second gear plate 46 connected to the foot pedal 49 move downwards along the second slide rail 43. The movement of the second gear plate 46 causes the meshing gear 47 to rotate, which in turn drives the first gear plate 45 to move upwards along the first slide rail 42. As the first gear plate 45 moves upwards, the locking plate 41 fixed on it gradually approaches and eventually comes into close contact with the rotating disk 363. Since the locking plate 41 adopts a material and structure design similar to a brake pad, it generates a strong frictional force when it contacts the rotating disk 363, thereby effectively stopping the rotating disk 363. After the rotating disk 363 stops rotating, the training component connected to it immediately stops operating, avoiding accidental injury caused by loss of force and ensuring the safety and stability of the training process.
