Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation equipment, and in particular to a device for active muscle training of the lower limbs. Background Technology
[0002] Rehabilitation training is a behavior that promotes the recovery of limb function through exercise. When performing rehabilitation work, rehabilitation equipment is usually needed to simulate various training situations. Different types of rehabilitation equipment can train different parts of the patient's body.
[0003] In existing technologies, leg-raising devices are commonly used to train patients' lower limbs. These devices mainly consist of a set of levers and weights, which can simulate leg-raising movements and require patients to continuously raise their legs to train muscle extension capabilities. However, during repositioning, they can rely on gravity to directly reposition the legs, thus failing to train the patient's lower limb retraction movements. As a result, the overall training effect of the device is poor. Therefore, a device for active lower limb muscle training is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a device for active lower limb muscle training, which aims to improve the problem in the prior art that "existing lower limb training devices mainly train patients' leg raising movements and cannot effectively train patients' lower limb retraction movements".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for active lower limb muscle training, comprising a support plate, a sliding frame fixedly connected to the upper surface of the support plate, a sliding plate slidably connected to the outer wall of the sliding frame, a resistance component provided on the rear surface of the support plate, the resistance component comprising a support frame, the support frame fixedly connected to the rear end of the support plate, a damping shaft installed on the inner wall of the support frame, a transmission belt installed on the outer wall of the damping shaft, a limit block fixedly connected to the outer wall of the transmission belt, a stop block penetrating and slidably connected to the inner wall of the sliding plate, the stop block and the sliding plate being elastically connected by a support spring, the front surface of the limit block being set as an inclined surface, and an adjustment component provided on the upper surface of the sliding plate.
[0006] As a further description of the above technical solution:
[0007] The resistance components are provided in multiple sets, and the multiple sets of resistance components are symmetrically arranged with the center line of the slide plate as the axis of symmetry. The limiting blocks on the outer wall of the two sets of transmission belts face opposite directions.

[0009] The adjustment component includes a lever, which is fixedly connected to the upper surface of the stop and slidably connected to the upper surface of the slide plate.
[0010] As a further description of the above technical solution:
[0011] The upper end of the skateboard is fixedly connected to a buckle, which is U-shaped.
[0012] As a further description of the above technical solution:
[0013] The end of the latch near the lever is angled.
[0014] As a further description of the above technical solution:
[0015] The support plate is fixedly connected to both its left and right ends, and the upper surface of the fixed plate is provided with threaded holes.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by setting two sets of opposing resistance components, when the patient raises his leg, the slide will move upward. One set of transmission belts will provide resistance to the patient's leg raising by blocking the limit block. When the patient swings his lower limb in the opposite direction, the other set of transmission belts will block the other set of limit blocks by opposing limit blocks on its surface. In this way, resistance can be provided for the slide to descend. This setting allows the patient to be trained when raising and lowering his lower limb, and the overall device has a good training effect.
[0022] 2. In this utility model, by setting an adjustment component, when only one of the lifting and retraction behaviors needs to be trained, the corresponding lever can be moved to drive the unused stop block forward, and the stop block can be fixed by the corresponding buckle. In this way, the side limit block will no longer be restricted when moving up and down, and the operator can freely adjust to train one behavior. The overall device has good applicability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a device for active lower limb muscle training, comprising a support plate 1 for supporting the entire device, a sliding frame 2 for guiding the movement of a sliding plate 3 fixedly connected to the upper surface of the support plate 1, a sliding plate 3 for supporting the patient's lower limb slidably connected to the outer wall of the sliding frame 2, and a resistance component 5 for restricting the free movement of the sliding plate 3 provided on the rear surface of the support plate 1. The resistance component 5 includes a support frame 51 for supporting the entire resistance component 5, the support frame 51 being fixedly connected to the rear end of the support plate 1, and a damping shaft 52 for restricting the free movement of a transmission belt 53 installed on the inner wall of the support frame 51. The damping shaft 52 is prior art, and it has a certain resistance when rotating. This resistance can assist the patient in training lifting and retraction movements. Due to the prior art, and as can be understood by those skilled in the art... Therefore, this case will not be described in detail. The outer wall of the damping shaft 52 is equipped with a transmission belt 53 for supporting the limiting block 54. The outer wall of the transmission belt 53 is fixedly connected to the limiting block 54 for blocking the stop block 55. The inner wall of the slide plate 3 is slidably connected to the stop block 55. The stop block 55 and the slide plate 3 are elastically connected by a support spring 56. The support spring 56 will push the stop block 55 outward at all times. The front surface of the limiting block 54 is set as an inclined surface. When the stop block 55 and the inclined surface of the limiting block 54 are pressed against each other, the stop block 55 will be forced to move into the support frame 51, so as to compress the support spring 56 and make it contract. When the stop block 55 and the limiting block 54 are in contact with each other in a plane, the stop block 55 will not be able to force the limiting block 54 to retract. The upper surface of the slide plate 3 is provided with an adjustment component 6 for limiting the movement of the stop block 55.
[0031] Reference Figure 2 - Figure 4 Multiple sets of resistance components 5 are provided, symmetrically arranged about the center line of the slide plate 3. The limiting directions provided by the two sets of resistance components 5 are opposite, and the limiting blocks 54 on the outer walls of the two sets of transmission belts 53 face opposite directions. Because the limiting blocks 54 in the two sets of resistance components 5 face opposite directions, one set of transmission belts 53 can be used to limit the upward movement of the support frame 51, while the other set of transmission belts 53 can be used to limit the downward movement of the support frame 51. The adjusting component 6 includes a lever 61 for facilitating the operator to move the stop block 55. The lever 61 is fixedly connected to the upper surface of the stop block 55. The slide block 61 is connected to the upper surface of the slide plate 3. By moving the lever 61, the stop block 55 can be separated from the limit block 54. The upper end of the slide plate 3 is fixedly connected to a buckle 62 to restrict the movement of the lever 61. The buckle 62 is made of plastic and has elastic deformation capability. It will elastically deform when squeezed. The buckle 62 is U-shaped. When the lever 61 is in the middle groove of the buckle 62, the lever 61 will not be able to move back and forth. The end of the buckle 62 near the lever 61 is set to be inclined. When the inclined side of the buckle 62 is squeezed, the end of the buckle 62 near the lever 61 will tilt upward.
[0032] Reference Figure 1 - Figure 3 The support plate 1 is fixedly connected to the left and right ends of the support plate 1 with fixing plates 7 for fixing the support plate 1. The upper surface of the fixing plate 7 is provided with threaded holes. The fixing plate 7 can be fixed to a specific working plane by installing bolts. The upper end of the slide plate 3 is equipped with a clamping sleeve 4 for fixing the patient's lower limbs. The lower end of the support frame 51 is fixedly connected with a support foot 8 for wrapping the limiting block 54. By setting the support foot 8, the limiting block 54 can be prevented from hooking the bed sheet or other items when rotating.
[0033] Working principle: Before using the whole device, the support plate 1 needs to be fixed to the appropriate working surface with bolts through the threaded holes on the fixing plate 7 to ensure the device is stable. The patient puts the lower limb into the clamping sleeve 4 at the upper end of the slide plate 3, adjusts to a comfortable position, and is ready to start training.
[0034] When the patient raises their leg, the slide plate 3 moves upward along the sliding frame 2. At this time, the resistance component 5 on one side, with the center line of the slide plate 3 as the axis of symmetry, begins to function. The transmission belt 53 in the resistance component 5 is pulled as the slide plate 3 rises, and the limiting block 54 on the outer wall of the transmission belt 53 also moves accordingly. During this process, the resistance generated by the damping shaft 52 is transmitted through the transmission belt 53, providing resistance for the patient to raise their leg, thereby exercising the lower limb muscles when the patient raises their leg. At the same time, since the inclined surface of the front surface of the limiting block 54 on the other side is opposite to the stop block 55, when it comes into contact with the stop block 55 that is slidably connected to the inner wall of the slide plate 3, the stop block 55 will be squeezed by the inclined surface of the limiting block 54 and forced to move into the support frame 51, thereby squeezing the support spring 56 to contract it. In this way, the limiting block 54 on this side can pass through the slide plate 3 normally.
[0035] If a patient or medical staff wants to train only one of the lifting or retraction movements, this can be achieved by adjusting component 6. By moving the lever 61, since the lever 61 is fixedly connected to the upper surface of the stop block 55 and slides through and is connected to the upper surface of the slide plate 3, the movement of the lever 61 will cause the stop block 55 to move forward. When the stop block 55 moves to a certain position, it will be locked in the buckle 62 at the upper end of the slide plate 3. The buckle 62 is U-shaped and the end near the lever 61 is inclined. When the lever 61 enters the groove of the buckle 62, the lever 61 is restricted from moving forward or backward. At this time, the corresponding stop block 55 separates from the limiting block 54, and the up and down movement of the limiting block 54 on this side is no longer restricted. That is, the resistance component 5 on this side no longer generates resistance to the movement of the slide plate 3, thereby realizing the adjustment of the single-movement training mode.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
