Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rehabilitation training equipment, in particular to an ankle movement rehabilitation trainer. Background Art
[0002] The ankle joint is composed of the articular surfaces at the lower ends of the tibia and fibula and the trochlea of the talus, so it is also called the talocrural joint. The lower articular surface of the tibia and the medial and lateral ankle articular surfaces together form a "冂"-shaped articular fossa that accommodates the trochlea of the talus (articular head). Since the trochlear joint surface is wider in the front and narrower in the back, when the foot is dorsiflexed, the wider front part enters the fossa and the joint is stable; but when the foot is plantarflexed, such as when walking downhill, the narrower back part of the trochlea enters the fossa, the ankle joint is loose and can move laterally, and at this time the ankle joint is prone to sprains or even fractures. And during the later recovery process, patients generally lie in bed all the time, which is not conducive to recovery. Therefore, rehabilitation training is needed, which is beneficial to accelerating the blood circulation of the affected limb and promoting healing. In the prior art, there is no rehabilitation trainer designed for use in bed. For different people, the sizes of their feet and the magnitudes of the rehabilitation training forces required are different. If the rehabilitation trainer cannot fit better with the feet of the patients in bed, the rehabilitation effect will be poor and the purpose of rehabilitation training cannot be achieved.

The adjustment seat 2 is arranged in the pedal 3. Among them, the mounting seat 1 is connected to the fixing assembly and plays the role of installation. The adjustment seat 2 is fixed on the mounting seat 1 by the first adjustment screw 9. Under the action of the first adjustment hole 10, the upper and lower positions of the adjustment seat 2 can be fine-tuned to better adapt to feet of different sizes, thereby achieving a better exercise effect. The function of the reset spring 4 is to push the foot pedal 3 away from the adjustment seat 2. The function of the fixing nut 8 is to install the adjustment handle 6 on the spring sleeve 5. The spring sleeve 5 is used to install the reset spring 4 and the adjustment handle 6. The spring pressing piece 7 is fixed on the end of the adjustment handle 6. The elastic force of the reset spring 4 can be adjusted by rotating the adjustment handle 6, so that rehabilitation can be achieved better and faster. The fixing nut 8 in this embodiment is fixedly connected to the spring sleeve 5 to prevent the fixing nut 8 from rotating when the adjustment handle 6 is rotated. The first adjustment screw 9 is a combination of a bolt and a nut in the prior art, which facilitates the adjustment between the mounting seat 1 and the adjustment seat 2. Four first adjustment holes 10 are provided between the mounting seat 1 and the adjustment seat 2, and each first adjustment hole 10 is provided with a first adjustment screw 9.
