Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation exercisers, in particular to an arm rehabilitation exerciser. Background Art

[0002] Patients with limb injuries and other diseases are generally unable to walk and need to lie in bed for a long time for corresponding treatment. However, the arm muscles of patients who lie in bed for a long time are prone to atrophy, resulting in the inability of the patients' arms to bear weight after recovery, affecting the patients' lives. Therefore, patients who lie in bed for a long time need to undergo simple arm rehabilitation training to ensure that the patients' arm muscles remain active. At present, when many patients train their arms, most of them only pull the trainer repeatedly in one direction for exercise, and the strength of pulling the trainer cannot be adjusted, so the strength cannot be changed according to the patient's recovery situation.

[0003] After searching, Chinese patent publication (announcement) No. CN218636310U discloses an arm rehabilitation exerciser. This patent has the advantages of being able to move the patient's arm in different directions and adjusting the training intensity through the setting of a driving mechanism and an elastic member. However, when the device is in use, its pressure spring may have insufficient spring force after long-term use, and it is inconvenient to replace the pressure spring, which affects the patient's arm training effect. Therefore, it is necessary to design an arm rehabilitation exerciser. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 As shown, an arm rehabilitation exerciser comprises a first base 1 and a second base 2. The upper surfaces of the first base 1 and the second base 2 are both provided with mounting grooves 3. The inner wall of the mounting groove 3 is rotatably connected with a fixing frame 4. The inner side wall of the fixing frame 4 is provided with a limiting groove 5. The lower surface of the fixing frame 4 is provided with a bottom plate 6. The lower surface of the bottom plate 6 is threadedly connected with a bolt 7. The inner wall of the fixing frame 4 is slidably connected with a movable plate 8. The movable plate 8 is slidably connected with the limiting groove 5. The upper surface of the movable plate 8 is rotatably connected with a fixing column 9. The bolt 7 is threadedly connected with the fixing frame 4.

[0023] In this embodiment, one end of the fixed column 9 passes through the inner top wall of the fixed frame 4 and extends to the upper surface of the fixed frame 4. A stretching assembly 10 is provided on the upper surface of the movable plate 8. The stretching assembly 10 includes a fixed disk 11 and a spring 12. The fixed column 9 is slidably connected to the fixed frame 4. The top end of the fixed column 9 is threadedly connected to the side plate 13, and the inner wall of the side plate 13 is rotatably connected to the handle 14.

[0024] During specific use, the tensioning component 10 may have the disadvantage of reduced tension of the spring 12 during long-term use. At this time, first unscrew the bolt 7, then the base plate 6 can be removed, and the fixing column 9 is screwed to disengage the threaded connection between the fixing column 9 and the side plate 13. At this time, the base plate 6 can slide out of the limiting groove 5 and drive the fixing column 9 to disengage from the fixing frame 4, so that the tensioning component 10 can be replaced. After replacement, it can be installed in the reverse order of the disassembly method, so that when the exerciser is used for a long time, the spring 12 of the tensioning component 10 can have a better tension effect, thereby ensuring the patient's exercise efficiency and quality.

[0025] In this embodiment, a universal self-locking wheel 15 is provided on the lower surface of the first base 1 .

[0026] During specific use, the first base 1 can drive the movement of the universal self-locking wheel 15 when it moves, which has the effect of facilitating movement.

[0027] In this embodiment, a support leg 16 is fixedly connected to the lower surface of the second base 2 .

[0028] During specific use, the support legs 16 can provide support for the second base 2, making the second base 2 more stable.

[0029] In this embodiment, a slide groove 17 is formed on the inner wall of the second base 2 , and the first base 1 is slidably connected to the slide groove 17 .

[0030] During specific use, the first base 1 can slide in the slide groove 17 on the inner wall of the second base 2. When the first base 1 moves, the universal self-locking wheel 15 is driven to move along, and the universal self-locking wheel 15 is locked after the movement.

[0031] In this embodiment, a threaded rod 18 is rotatably connected to the inner side wall of the slide groove 17 , and the threaded rod 18 is threadedly connected to the first base 1 .

[0032] During specific use, the threaded rod 18 can perform threaded motion with the first base 1 when rotating, thereby driving the first base 1 to slide in the sliding groove 17 .

[0033] In this embodiment, one end of the threaded rod 18 passes through the inner wall of the slide groove 17 and extends to the side of the second base 2 , and one end of the threaded rod 18 is fixedly connected to the turntable 19 .

[0034] During specific use, the setting of the turntable 19 can facilitate the rotation of the threaded rod 18 when the turntable 19 is rotated.

[0035] Working principle: During use, the patient stands on the upper surface of the first base 1 and the second base 2, and pulls the handle 14 with both hands. At this time, the handle 14 rotates on the inner wall of the side plate 13, thereby driving the angle adjustment of the fixed frame 4 through the fixed column 9. When the handle 14 is pulled, the side plate 13 can be driven, and then the side plate 13 drives the fixed column 9 so that the fixed column 9 drives the movable plate 8 to slide in the limiting groove 5. At this time, the spring 12 of the stretching component 10 is in a compressed state. Slowly release your hand, and under the action of the spring 12, the movable plate 8 is reset to achieve the effect of arm exercise. The stretching component 10 will have the disadvantage of reduced tension of the spring 12 during long-term use. At this time, first unscrew the bolt 7, the base plate 6 can be removed, and the fixed column 9 is screwed so that the fixed column 9 and the side plate 13 are disconnected from the threaded connection. At this time, the base plate 6 can slide out of the limiting groove 5. , and drives the fixing column 9 to separate from the fixing frame 4, so that the stretching component 10 can be replaced. After replacement, it is installed in the reverse operation of the disassembly method, so that when the exerciser is used for a long time, the spring 12 of the stretching component 10 can have a good pulling effect, ensuring the patient's exercise efficiency and quality. When the turntable 19 is rotated, the threaded rod 18 can be driven to rotate so that the threaded rod 18 can perform threaded movement with the first base 1. Due to the sliding connection between the first base 1 and the slide groove 17, the first base 1 can be limited, thereby driving the first base 1 to slide in the slide groove 17. At this time, the universal self-locking wheel 15 on the lower surface of the first base 1 moves. After adjusting the distance between the first base 1 and the second base 2, the universal self-locking wheel 15 is locked and the equipment can be used for exercise, which is convenient for people of different body shapes to use the exerciser.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
