[0002] Patients with lower limb fractures usually need the assistance of their family members when performing ankle dorsiflexion and dorsiflexion exercises, and it is difficult to control the intensity of the exercise during the exercise. If the intensity is too high, the patient will feel unbearable pain, and if the intensity is too low, the training intensity will not be adequate. In order to help patients recover foot function as soon as possible, an exerciser is needed that allows patients to exercise independently while lying in bed, and the intensity can be adjusted according to their own feelings. For this purpose, we propose an ankle exerciser. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] Example 1

[0024] See also Figure 1-5 The utility model provides a technical solution: a foot and ankle exerciser, comprising a main frame 1, a shaft 11 is relatively penetrated on the main frame 1, a foot pedal 2 is installed on the shaft 11, both sides of the foot pedal 2 are penetrated by the shaft 11, a strap 1 21 is installed on the foot pedal 2, there are two straps 1 21, and corresponding Velcro is set on each strap 1 21, and also includes:

[0025] The torsion spring 3 is sleeved on the shaft 11, one end of the torsion spring 3 is fixed to the shaft 11, and the other end is fixed to the main support 1;

[0026] The pressure regulating mechanism 4 is installed on the main support 1 and connected to the shaft 11. The pressure regulating mechanism 4 controls the friction force that needs to be overcome when the shaft 11 rotates.

[0027] A support plate 60 is sleeved on the shaft 11, and the support plate 60 and the shaft 11 are rotatably connected. The support plate 60 is L-shaped, and a groove 61 is provided on the support plate 60. A strap 62 is installed on the support plate 60. There are two straps 62, and both are provided with corresponding Velcro.

[0028] The patient's foot is placed on the foot pedal 2, and the foot is fixed on the foot pedal 2 by the strap 1 21. Then, the patient's leg is relaxed and falls onto the support plate 60, and the leg is fixed on the support plate 60 by the strap 2 62. The L-shaped support plate 60 prevents the patient's leg from hanging in the air, thereby increasing the comfort during exercise. Then, the torsion spring 3 is compressed and reset by continuously exerting force on the sole of the foot or the heel, thereby achieving the purpose of exercising the ankle. The setting of the groove 1 61 prevents the foot pedal 2 from being blocked when rotating.

[0029] The pressure regulating mechanism 4 includes a cylinder 41 fixed on the main support 1, and the cylinder 41 is provided with a slide groove 42. There are a plurality of slide grooves 42, which are arranged in a ring array on the cylinder 41. An extrusion block 43 is installed in the slide groove 42. The top of the extrusion block 43 is inclined. A rubber block 44 is installed on the top of the extrusion block 43. The rubber block 44 is arc-shaped. It also includes a transmission mechanism 5 installed on the cylinder 41. The transmission mechanism 5 accurately controls the size of the friction force that needs to be overcome when the shaft 11 rotates and limits it after adjustment.

[0030] The transmission mechanism 5 includes a thread 51 arranged on the second cylinder 41, a third cylinder 52 is sleeved on the second cylinder 41, a screw groove 53 is opened on the inner wall of the third cylinder 52, and a torsion block 54 is sleeved and fixed on the third cylinder 52.

[0031] After the patient has recovered for a period of time, the pressure of the foot pedal 2 is too small, and the twist block 54 is rotated. The twist block 54 drives the cylinder 2 41 to move in the direction of the extrusion block 43 under the drive of the thread 51 and the screw groove 53. As the cylinder 2 41 approaches, the inclined top end of the extrusion block 43 is squeezed by the cylinder 2 41, and the extrusion block 43 drives the rubber block 44 to fit with the shaft. The farther the cylinder 2 41 moves, the greater the downward distance of the extrusion block 43, that is, the tighter the rubber block 44 fits with the shaft 11, and the greater the friction force on the shaft 11 when it rotates, thereby adapting to the rehabilitation exercises of patients in various recovery stages.

[0032] Example 2

[0033] A holder 70 is installed at the top of the footrest 2 , a buckle 71 is installed in the holder 70 , and a rope 72 is connected to the buckle 71 .

[0034] When the patient has difficulty exerting force on his legs, the rope 72 can be pulled. The rope 72 applies tension to the top of the foot pedal 2, driving the foot pedal 2 to rotate and allowing the patient's feet to move. The patient's hands exert force throughout the process. Appropriate movement is helpful for the patient's recovery.

[0035] A shaft 2 81 is installed at the bottom of the main support 1.

[0036] When the rope 72 passes around the shaft 81, under the action of the shaft 81, pulling the rope 72 will cause the foot pedal 2 to rotate in the opposite direction, so that the patient's foot can move in a larger range, the range of movement of the foot is increased, and rehabilitation is helped.

[0037] The working principle of the utility model is as follows: the patient's foot is placed on the foot pedal 2, and the foot is fixed on the foot pedal 2 by the strap 1 21, and then the patient's leg is relaxed and falls on the support plate 60, and the leg is fixed on the support plate 60 by the strap 2 62. The L-shaped support plate 60 prevents the patient's leg from hanging in the air, thereby increasing the comfort during the exercise, and then the torsion spring 3 is compressed and reset by continuously exerting force on the sole or heel of the foot, thereby achieving the purpose of exercising the ankle. After the patient recovers for a period of time, the foot pedal 2 is When the pressure is too low, the twist block 54 is rotated, and the twist block 54 drives the cylinder 2 41 to move in the direction of the extrusion block 43 under the drive of the thread 51 and the screw groove 53. As the cylinder 2 41 approaches, the inclined top end of the extrusion block 43 is squeezed by the cylinder 2 41, and the extrusion block 43 drives the rubber block 44 to fit with the shaft. The farther the cylinder 2 41 moves, the greater the downward distance of the extrusion block 43, that is, the tighter the rubber block 44 fits with the shaft 11, the greater the friction force on the shaft 11 when it rotates, thereby adapting to the rehabilitation exercises of patients in various recovery stages.
