Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation equipment, and in particular relates to a rehabilitation training device for a hospital bed. Background Art

[0002] Rehabilitation training refers to physical activities that are conducive to restoring or improving function after an injury. Except for serious injuries that require rest and treatment, general injuries do not require complete cessation of physical exercises. Appropriate and scientific physical exercises have a positive effect on the rapid healing of injuries and the promotion of functional recovery.

[0003] When a patient injures his leg, he usually needs to lie flat on the bed to recuperate. During the recuperation period, he cannot get out of bed to perform leg rehabilitation training. Currently, most leg rehabilitation equipment cannot be used on hospital beds. If the patient lies in bed for a long time, the leg muscles will atrophy, which is not conducive to the patient getting out of bed and walking after recovery.

[0004] A Chinese utility model patent (publication number: CN221451631U) discloses a leg rehabilitation device for a hospital bed. When in use, the patient's legs push the push plate, overcoming the prestress of the spring and driving the push plate to move.

[0005] However, in actual use, it has only one push plate, which can only achieve synchronous movement of both legs, but cannot achieve alternating movement of the legs, resulting in poor exercise effect. Utility Model Content

[0006] The purpose of the utility model is to provide a rehabilitation training device for a hospital bed, which is used to solve the problem that the existing training devices cannot achieve alternating movements of the legs.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0008] A rehabilitation training device for a hospital bed, comprising:

[0009] A connector that can be detachably mounted on the footboard of the hospital bed;

[0010] A fixing frame, the fixing frame is mounted on the connecting piece, and a mounting groove is vertically opened in the middle of the fixing frame;

[0011] A rotating frame, wherein a hinge shaft is provided in the middle of the rotating frame, the hinge shaft is rotatably mounted on the fixed frame and is located in the mounting groove, and sliding grooves are provided at both ends of the rotating frame;

[0012] Sliding members, the sliding members are two and are slidably mounted on both sides of the fixed frame, the sliding members include sliding rods, the two sliding rods pass through the fixed frame and are slidably mounted in a sliding groove respectively;

[0013] The hinge shaft and the two sliding rods are parallel to each other and are located in the same plane with a certain angle to the horizontal plane;

[0014] A pedal is mounted on the sliding member.

[0015] It is further defined that the side walls on both sides of the fixing frame are each provided with two upper and lower communicating grooves parallel to each other, and a limiting clamp ring is installed in the communicating groove;

[0016] The sliding member further includes a guide rod, wherein the guide rod is parallel to the sliding rod;

[0017] The guide rod and the sliding rod are both inserted into the corresponding connecting grooves;

[0018] The side walls of the sliding rod and the guide rod are both provided with limiting grooves, and the limiting clamping ring is clamped in the limiting grooves.

[0019] This structural design allows the sliding rod to pass through the fixed frame through the connecting groove and be slidably installed in the sliding groove, providing avoidance space. At the same time, the mutual cooperation between the limit clamp and the limit groove is utilized to realize the sliding installation between the sliding part and the fixed frame. The cooperation between the guide rod and the connecting groove is then utilized to limit the freedom of the sliding part to rotate around the sliding rod. The structure is simple and practical.

[0020] It is further defined that the limiting clamp includes two C-shaped frames.

[0021] With this structural design, a complete limit clamp ring is formed by two C-shaped frames. During installation, the sliding rod and the guide rod of the sliding member can be inserted into the connecting groove, and then one of the C-shaped frames can be installed first. Then, the sliding member can be slid to one end of the fixed frame so that the C-shaped frame is stuck in the limit groove, and then the other C-shaped frame can be installed to form a complete limit clamp ring. The installation is more convenient and more practical.

[0022] It is further defined that a receiving arc plate is installed laterally at the lower end of the pedal away from the side of the footboard.

[0023] This structural design, through the supporting arc plate, provides vertical support to the patient's heel when the patient steps on the pedal, preventing the patient's foot from slipping off the pedal, and is highly practical.

[0024] It is further defined that the receiving arc plate is rotatably mounted on the pedal.

[0025] This structural design allows the receiving arc plate to be folded by rotating the receiving arc plate, making storage more convenient and more practical.

[0026] It is further defined that the pedal is rotatably mounted on a sliding member, and a locking mechanism is installed between the pedal and the sliding member.

[0027] This structural design, through the rotational connection between the pedal and the sliding part, cooperates with the locking mechanism. When in use, the pedal can be rotated to a position perpendicular to the fixed frame and locked with the locking mechanism for the patient to step on. After use, the locking structure can be opened, and the pedal can be rotated around the sliding part to fit the fixed frame, making it more convenient to store.

[0028] It is further defined that the locking mechanism includes a fixed column, a hinge block, a fixed fork and a locking spring;

[0029] The fixing column is vertically fixedly mounted on the side of the sliding member away from the sliding rod, and a limiting hole is provided on the fixing column;

[0030] The hinge block is fixedly mounted on the pedal and rotatably mounted on the fixed column;

[0031] A slot is provided on the pedal, and the fixed fork is slidably installed in the slot;

[0032] The locking spring is located between the rear end of the fixed fork and the pedal;

[0033] When the pedal is in use, the front end of the fixing fork passes through the pedal and is inserted into the limiting hole.

[0034] Such a structural design forms a locking mechanism through a fixed column, a hinge block, a fixed fork and a locking spring, thereby fixing the pedal when the training device is in use. It has a simple structure, is easy to use and has strong practicality.

[0035] It is further defined that the fixing column is further provided with a secondary hole, and when the pedal is in contact with the fixing frame, the fixing fork is passed through the secondary hole.

[0036] This structural design, through the setting of the auxiliary hole, can re-fix the pedal and the sliding member by passing the fixing fork through the auxiliary hole when the pedal is folded, avoiding accidental expansion of the pedal relative to the sliding member, and is highly practical.

[0037] It is further defined that the side wall of the fixing frame is provided with a through hole, and a top block is passed through the through hole;

[0038] A ring groove is formed on the side of the through hole away from the rotating frame, and a protrusion is screwed into the ring groove;

[0039] A compression spring is provided between the top block and the protrusion, and one end of the top block away from the protrusion presses against the side wall of the rotating frame.

[0040] With this structural design, through the cooperation between the top block, the protrusion and the extrusion spring, when the patient needs a greater exercise difficulty, the protrusion can be tightened, and the extrusion spring can apply greater pressure to the top block, so that the top block is more closely attached to the rotating frame, so that the rotation of the rotating frame needs to overcome greater friction. Conversely, the protrusion can be loosened.

[0041] It is further defined that the fixing frame is rotatably mounted on the connecting member, and a locking member is installed between the fixing frame and the connecting member.

[0042] This structural design, through the rotational connection between the fixing frame and the connecting piece, cooperates with the locking piece. When in use, the fixing frame can be rotated to a position perpendicular to the footboard and locked with the locking piece. After use, the locking piece can be opened, and the fixing frame can be rotated around the connecting piece to fit the footboard, making storage more convenient.

[0043] The utility model adopting the above technical solution has the following advantages:

[0044] 1. Through the mutual cooperation of the connecting parts, the fixed frame, the rotating frame, the sliding parts and the pedals, when one pedal is stepped on, the other pedal moves forward under the action of the rotating frame, allowing the other foot to step on it, thereby achieving alternating leg movements and achieving better exercise effects;

[0045] 2. The connecting groove is used for the sliding rod to pass through the fixed frame and slide into the sliding groove, providing avoidance space. At the same time, the sliding assembly between the sliding member and the fixed frame is realized by the mutual cooperation between the limiting clamp and the limiting groove. The freedom of the sliding member to rotate around the sliding rod is limited by the cooperation between the guide rod and the connecting groove. The structure is simple and practical.

[0046] 3. The supporting arc plate provides vertical support to the patient's heel when the patient steps on the pedal, preventing the patient's foot from slipping off the pedal, which is highly practical.

[0047] 4. Through the rotational connection between the pedal and the sliding member, combined with the locking mechanism, when in use, the pedal can be rotated to a position perpendicular to the fixing frame and locked with the locking mechanism for the patient to step on; after use, the locking mechanism can be opened, and the pedal can be rotated around the sliding member to fit the fixing frame, making it more convenient to store;

[0048] 5. Through the cooperation between the top block, the protrusion and the extrusion spring, when the patient needs a higher level of exercise difficulty, the protrusion can be tightened, and the extrusion spring will apply greater pressure to the top block, so that the top block is more closely attached to the rotating frame, so that the rotation of the rotating frame needs to overcome greater friction. Conversely, the protrusion can be loosened;

[0049] 6. Through the rotational connection between the fixing frame and the connecting piece, in conjunction with the locking piece, when in use, the fixing frame can be rotated to a position perpendicular to the footboard and locked with the locking piece; after use, the locking piece can be opened, and the fixing frame can be rotated around the connecting piece to fit the footboard, making storage more convenient.

In addition, directional terms such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back" mentioned in the embodiments are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0071] like Figures 1 to 11 As shown, the present invention is a rehabilitation training device for a hospital bed, comprising:

[0072] A connector 2 detachably mounted on the footboard 10 of the hospital bed 1;

[0073] The fixing frame 3 is installed on the connecting member 2, and a mounting groove 31 is vertically opened in the middle of the fixing frame 3;

[0074] The rotating frame 4 has a hinge shaft in the middle, which is rotatably mounted on the fixed frame 3 and located in the mounting groove 31. Both ends of the rotating frame 4 have sliding grooves 40.

[0075] Sliding members 5, there are two sliding members 5, and they are slidably mounted on both sides of the fixing frame 3. The sliding members 5 include sliding rods 50. The two sliding rods 50 pass through the fixing frame 3 and are slidably mounted in a sliding groove 40 respectively;

[0076] The hinge axis and the two sliding rods 50 are parallel to each other and are located in the same plane with a certain angle to the horizontal plane;

[0077] Pedal 6 , which is mounted on the sliding member 5 .

[0078] Through the mutual cooperation of the connecting member 2, the fixed frame 3, the rotating frame 4, the sliding member 5 and the pedals 6, when one pedal 6 is stepped on, the other pedal 6 moves forward under the action of the rotating frame 4, allowing the other foot to step on it, thereby achieving alternating leg movements and achieving better exercise effects;

[0079] like Figure 3 and Figure 4 As shown, two upper and lower parallel communication grooves 32 are provided on both side walls of the fixing frame 3, and a limit clamp 33 is installed in the communication groove 32;

[0080] The sliding member 5 further includes a guide rod 51 , which is parallel to the sliding rod 50 ;

[0081] The guide rod 51 and the sliding rod 50 are both inserted into the corresponding connecting groove 32;

[0082] The side walls of the sliding rod 50 and the guide rod 51 are both provided with a limiting groove 510 , and the limiting clamping ring 33 is clamped in the limiting groove 510 .

[0083] In fact, according to actual conditions, it is also possible to choose to set a T-shaped block on the sliding member 5 and a T-shaped groove on the fixing frame 3 to achieve a sliding connection between the sliding member 5 and the fixing frame 3. In this embodiment, the sliding rod 50 passes through the fixing frame 3 through the connecting groove 32 and is slidably installed in the sliding groove 40, providing avoidance space. At the same time, the mutual cooperation between the limiting clamp 33 and the limiting groove 510 is utilized to achieve the sliding installation between the sliding member 5 and the fixing frame 3, and then the cooperation between the guide rod 51 and the connecting groove 32 is utilized to limit the freedom of the sliding member 5 to rotate around the sliding rod 50. The structure is simple and the practicality is strong.

[0084] like Figure 2 As shown, the limiting snap ring 33 includes two C-shaped frames.

[0085] In fact, according to actual conditions, the sliding rod 50 and the guide rod 51 can be cut off from the limit groove 510, and then connected with bolts, so that the sliding rod 50 and the guide rod 51 are detachably connected to achieve cooperation with the limit clamping ring 33. In this embodiment, a complete limit clamping ring 33 is formed by two C-shaped frames. During installation, the sliding rod 50 and the guide rod 51 of the sliding member 5 can be inserted into the connecting groove 32, and then one of the C-shaped frames can be installed first, and then the sliding member 5 can be slid to one end of the fixed frame 3 so that the C-shaped frame is stuck in the limit groove 510, and then the other C-shaped frame can be installed to form a complete limit clamping ring 33, which is more convenient to install and more practical.

[0086] like Figure 3As shown, a receiving arc plate 60 is installed laterally at the lower end of the pedal 6 away from the side of the footboard 10.

[0087] In fact, according to actual conditions, anti-slip structures such as anti-slip grooves can be provided on the pedal 6 to prevent the patient's feet from slipping. This embodiment uses the receiving arc plate 60 to vertically support the patient's heel when the patient steps on the pedal 6, thereby preventing the patient's foot from slipping off the pedal 6, and is highly practical.

[0088] The receiving arc plate 60 is rotatably mounted on the pedal 6 .

[0089] In fact, the receiving arc plate 60 can also be directly fixedly installed on the pedal 6 according to actual conditions. In this embodiment, the receiving arc plate 60 can be folded by rotating the receiving arc plate 60, which makes storage more convenient and more practical.

[0090] The pedal 6 is rotatably mounted on the sliding member 5 , and a locking mechanism is installed between the pedal 6 and the sliding member 5 .

[0091] In fact, according to actual conditions, the pedal 6 can be directly fixed on the sliding member 5 without considering the storage function. In this embodiment, the pedal 6 is connected to the sliding member 5 by rotation and cooperates with the locking mechanism. When in use, the pedal 6 can be rotated to a position perpendicular to the fixing frame 3 and locked with the locking mechanism for the patient to step on. After use, the locking structure can be opened, and the pedal 6 can be rotated around the sliding member 5 to fit the fixing frame 3, which is more convenient for storage.

[0092] like Figure 4 and Figure 5 As shown, the locking mechanism includes a fixing post 52, a hinge block 61, a fixing fork 62 and a locking spring 63;

[0093] The fixing column 52 is vertically fixedly installed on the side of the sliding member 5 away from the sliding rod 50, and a limiting hole 521 is defined on the fixing column 52;

[0094] The hinge block 61 is fixedly mounted on the pedal 6 and rotatably mounted on the fixed column 52;

[0095] The pedal 6 is provided with a slot 620, and the fixing fork 62 is slidably installed in the slot 620;

[0096] The locking spring 63 is located between the rear end of the fixed fork 62 and the pedal 6;

[0097] When the pedal 6 is in use, the front end of the fixing fork 62 passes through the pedal 6 and is inserted into the limiting hole 521 .

[0098] In fact, according to actual conditions, a bolt that is screwed through the pedal 6 and rests on the sliding member 5 can be selected to complete the folding and fixation. In this embodiment, a locking mechanism is formed by a fixing column 52, a hinge block 61, a fixing fork 62 and a locking spring 63 to complete the fixation of the pedal 6 when the training device is used. The structure is simple, easy to use and highly practical.

[0099] like Figure 5 As shown, the fixing column 52 is further provided with an auxiliary hole 522 . When the pedal 6 is in contact with the fixing bracket 3 , the fixing fork 62 is inserted into the auxiliary hole 522 .

[0100] Through the setting of the auxiliary hole 522, when the pedal 6 is folded, the fixing fork 62 is passed through the auxiliary hole 522 to re-fix the pedal 6 and the sliding member 5, thereby avoiding accidental expansion of the pedal 6 relative to the sliding member 5, which is highly practical.

[0101] like Figure 8 and Figure 9 As shown, the side wall of the fixing frame 3 is provided with a through hole, and a top block 34 is passed through the through hole;

[0102] A ring groove 350 is formed on the side of the through hole away from the rotating frame 4, and a protrusion 35 is screwed into the ring groove 350;

[0103] A compression spring 340 is provided between the top block 34 and the protrusion 35 , and one end of the top block 34 away from the protrusion 35 presses against the side wall of the rotating frame 4 .

[0104] Through the cooperation between the top block 34, the protrusion 35 and the extrusion spring 340, when the patient needs a greater exercise difficulty, the protrusion 35 can be tightened, and the extrusion spring 340 can apply greater pressure to the top block 34, so that the top block 34 is more closely attached to the rotating frame 4, so that the rotation of the rotating frame 4 needs to overcome a greater friction force. Conversely, the protrusion 35 can be loosened.

[0105] like Figure 6 and Figure 11 As shown, the fixing frame 3 is rotatably mounted on the connecting member 2 , and a locking member 20 is installed between the fixing frame 3 and the connecting member 2 .

[0106] In fact, according to actual conditions, the fixing frame 3 can also be directly fixed on the connecting member 2. In this embodiment, the fixing frame 3 is connected to the connecting member 2 through rotation, and the locking member 20 is used. When in use, the fixing frame 3 can be rotated to a position perpendicular to the footboard 10 and locked with the locking member 20; after use, the locking member 20 can be opened, and the fixing frame 3 can be rotated around the connecting member 2 to fit the footboard 10, which is more convenient to store.

[0107] In this embodiment, when in use, the patient's feet are placed on a pedal 6 respectively, and the two feet step on the corresponding pedal 6 alternately. When stepping on the right pedal 6, for example, when stepping on the right pedal 6, the pedal 6 drives the sliding member 5 to move along the fixed frame 3 toward the direction of the footboard 10, and the sliding rod 50 drives the rotating frame 4 to rotate clockwise, thereby driving the left sliding member 5 to move along the fixed frame 3 away from the footboard 10. During this process, the sliding rod 50 slides in the slide groove 40;

[0108] When the right pedal 6 is stepped on to the bottom, the left pedal 6 is stepped on with the left foot to drive the right pedal 6 to reset.

[0109] The above describes in detail the rehabilitation training device for a hospital bed provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
