Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation tools, in particular to a lower limb rehabilitation exerciser. Background Art

[0002] After a child's lower limbs are injured and treated, in order to ensure the rehabilitation effect of the child's lower limbs, the child needs to undergo systematic lower limb rehabilitation training. For the rehabilitation training of the child's lower limbs, a lower limb rehabilitation exerciser is needed. Most of the existing lower limb rehabilitation exercisers are pedal-type exercisers, which assist the child's lower limbs in rehabilitation by simulating riding by pedaling. However, after such exercisers have been used for a period of time, in order to reduce the wear of the exercisers, the bearing parts of the exercisers need to be lubricated. However, it is currently difficult to lubricate the bearings of the exercisers. If the child lacks oil when using the exerciser alone, it is difficult for the child to lubricate the bearings by himself, which affects the child's normal rehabilitation exercise. For this reason, the utility model provides an improved lower limb rehabilitation exerciser that is easy to lubricate. Summary of the Invention

[0003] The disclosed embodiments relate to a lower limb rehabilitation exerciser, which is provided with a lubricating cylinder. By storing spare lubricating oil in the lubricating cylinder, when a loading bearing in the exerciser is short of oil, the lubricating oil inside the lubricating cylinder can be used to quickly replenish the oil, thereby avoiding the exerciser from getting stuck due to untimely oil replenishment. In addition, the oiling work of the exerciser is simple and convenient, and the exerciser is suitable for a wide range of people.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 6 :

[0027] Example 1:

[0028] The utility model proposes a lower limb rehabilitation exerciser, comprising: a supporting leg 1, which is a cylindrical structure; flexible protective tubes are provided at the left and right ends of the supporting leg 1; a supporting frame 2 is fixedly installed at the center position of the supporting leg 1; a mounting seat 3 is fixedly installed on the top of the supporting frame 2 by bolts; a loading bearing 4 is fixedly installed inside the mounting seat 3; a training shaft 6 is fixedly installed on the inner ring of the loading bearing 4; a lubrication through hole 5 is opened on the outer ring of the loading bearing 4; a lubrication cylinder 10 is fixedly installed at the front end of the mounting seat 3; an oil injection push rod 12 is slidably installed at the front end of the lubrication cylinder 10; an oil injection push plate 13 is fixedly installed at the rear end of the oil injection push rod 12; a trigger pressure plate 14 is fixedly installed at the front end of the oil injection push rod 12; and a docking pipe body 16 is fixedly installed at the rear end of the lubrication cylinder 10 in a left-right symmetrical arrangement.

[0029] The child sits on a bench or bedside, and then the child's feet are positioned on the two pedal members 8 respectively through the restraint belt 9, and then the child kicks the pedal members 8 to start training.

[0030] Embodiment 2, on the basis of embodiment 1, training cranks 7 are fixedly installed on the left and right ends of the training shaft 6; the outer ends of the two training cranks 7 face oppositely; the outer ends of the two training cranks 7 are rotatably installed with pedals 8; an elastic restraint belt 9 is fixedly installed on the pedal 8; lubricating oil is stored inside the lubrication cylinder 10; an oil filling hole is opened on the top of the lubrication cylinder 10, and a sealing member 11 is installed on the oil filling hole by threaded locking; the oil filling push rod 12 is a cylindrical structure; the oil filling push plate 13 is a disc-shaped structure; the oil filling push plate 13 is also slidably installed inside the lubrication cylinder 10.

[0031] During the training process, if the loading bearing 4 is stuck due to lack of oil and causes difficulty for the child to pedal the pedal 8, the child can press the trigger pressure plate 14, so that the trigger pressure plate 14 is forced to move the oil injection push rod 12 and the oil injection push plate 13 backward, so that the oil injection push plate 13 squeezes the lubricating oil inside the lubrication cylinder 10 by moving backward, so that the lubricating oil is affected by the squeezing and enters the interior of the loading bearing 4 through the docking tube body 16 and the lubrication through hole 5 in turn, thereby lubricating the loading bearing 4 and solving the problem of its sticking.

[0032] Embodiment 3, based on embodiment 2, the trigger pressure plate 14 is a disc-shaped structure; one end of a return spring 15 is embedded in the rear side of the trigger pressure plate 14; the other end of the return spring 15 is embedded in the front side wall of the lubrication cylinder 10; the two docking tube bodies 16 are respectively connected to the lubrication through holes 5 on the two loading bearings 4; the trigger pressure plate 14 will move backward with the oil injection push rod 12 and the oil injection push plate 13 when subjected to external pressure; when the oil injection push plate 13 moves backward, it will squeeze the lubricating oil inside the lubrication cylinder 10; the lubricating oil inside the lubrication cylinder 10 will be squeezed by the oil injection push plate 13 and enter the interior of the loading bearing 4 through the docking tube body 16 and the lubrication through hole 5.

[0033] After the oil filling is completed, by releasing the pressure on the trigger pressure plate 14, it moves back to its original position with the oil filling push rod 12 and the oil filling push plate 13 under the action of the return spring 15, so that the oil filling push plate 13 cancels the squeezing of the lubricating oil by moving backward, stops the injection of the lubricating oil, and then continues to pedal the pedal 8 to exercise.

[0034] The working principle of this embodiment is as follows:

[0035] During use, the child sits on a bench or bedside, and then uses the restraint belt 9 to position the child's feet on the two pedals 8 respectively. Then the child pedals the pedals 8 to start training. During the training process, if the loading bearing 4 is stuck due to lack of oil, which makes it difficult for the child to pedal the pedal 8, the child can press the trigger pressure plate 14, so that the trigger pressure plate 14 is forced to move the oil injection push rod 12 and the oil injection push plate 13 backward, so that the oil injection push plate 13 squeezes the lubricating oil inside the lubricating cylinder 10 by moving backward. The lubricating oil is squeezed and enters the interior of the loading bearing 4 through the connecting pipe body 16 and the lubricating through hole 5 in turn, thereby lubricating the loading bearing 4 and solving the problem of its sticking. After the oil filling is completed, by releasing the pressure on the trigger pressure plate 14, the oil filling push rod 12 and the oil filling push plate 13 are moved backward and restored under the action of the return spring 15, so that the oil filling push plate 13 cancels the squeezing of the lubricating oil by moving backward, stops the injection of the lubricating oil, and then continues to pedal the pedal 8 to exercise.
