Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation training, and in particular relates to an auxiliary supporting device for lower limb training. Background Art

[0002] Patients with lower limb movement disorders (such as lower limb fractures) have weak lower limb strength during the rehabilitation process, so they need auxiliary support devices. Auxiliary support devices are mainly used to support patients, assist patients in rehabilitation training, and assist patients in walking and activities.

[0003] The commonly used auxiliary support device includes two support frames arranged in parallel, which are fixed at the training site. During rehabilitation training, the hands are supported on the two support frames, and then the lower limb walking rehabilitation training is performed. However, this auxiliary support device needs to be fixed, so it has poor flexibility.

[0004] Based on this, a movable auxiliary support device has emerged, which includes two U-shaped support frames, which are arranged in parallel and a connecting rod is arranged between the two support frames. During rehabilitation training, the patient holds the top of the two support frames, lifts the support frames, and moves forward. After the support frames are stable, the patient's legs move forward to complete walking and train the lower limbs.

[0005] This auxiliary support device requires the patient to use the strength of the lower limbs to keep upright for a period of time when moving the support frame. It is suitable for patients with a certain support strength of the lower limbs, but not suitable for patients who have just started lower limb training. Therefore, the entire rehabilitation training process requires the cooperation of two auxiliary support devices, and the existing auxiliary support devices are less applicable. Utility Model Content

[0006] The utility model is intended to provide a lower limb training auxiliary support device, and the utility model is intended to solve the technical problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary support device for lower limb training, comprising two U-shaped support frames, a connecting rod is arranged between the two support frames, an auxiliary block is arranged at the bottom of one end of the two support frames, a groove is arranged in the auxiliary block, a roller is arranged in the groove, the bottom of the roller is located outside the auxiliary block, a rotating shaft is coaxially fixed on the roller, and the rotating shaft is rotatably connected to the auxiliary block; a limiting block is arranged on the rotating shaft, and a stop block is arranged on the groove; a torsion spring is arranged outside the rotating shaft, and the two ends of the torsion spring are respectively fixed in the rotating shaft and the groove.

[0008] Beneficial effects of this technical solution:

[0009] The two support frames support the patient, which can assist the patient in walking and conducting lower limb rehabilitation training. When the patient moves forward, the support frame is tilted up so that the roller in the auxiliary block contacts the ground, and the support frame is moved under the action of the roller until the roller drives the rotating shaft to rotate until the block and the limiting block are against each other, and the roller can no longer slide; at this time, the entire device moves forward, and then the tilted support frame is lowered so that the support frame contacts the ground to support the patient; after the support frame contacts the ground, the force on the roller disappears, and it is reset under the action of the torsion spring to facilitate the next movement. In the process of moving the device, the patient can be supported by the auxiliary block and the roller, and the patient moves forward again to achieve walking.

[0010] This technical solution can support the patient when the device is moved, reducing the force on the lower limbs. Compared with the existing technology, which requires the entire device to be lifted when moving, and the patient needs to fully use the lower limbs to bear the force, this technical solution can always support the patient and is suitable for the early stage of lower limb rehabilitation training.

[0011] In another preferred embodiment of the present invention, limiting blocks are provided on both sides of the roller on the rotating shaft, and two stoppers respectively cooperating with the limiting blocks are provided in the groove.

[0012] Beneficial effect: By arranging limiting blocks and stoppers on both sides of the roller, the limiting effect can be improved, and the force can be symmetrical, which can reduce the probability of damage to parts due to concentrated force.

[0013] In another preferred embodiment of the present invention, torsion springs are sleeved on both sides of the rotating shaft on the roller.

[0014] Beneficial effect: two torsion springs are arranged on the rotating shaft, so that the rotating shaft and the roller can be quickly reset.

[0015] In another preferred embodiment of the present invention, a support sleeve is fixed to the bottom of the support frame, and the longitudinal section of the support sleeve is conical with the large diameter end facing downward.

[0016] Beneficial effect: The setting of the support sleeve can increase the contact area between the support frame and the ground, thereby increasing the stability of use.

[0017] In another preferred embodiment of the present invention, a non-slip layer is provided at the bottom of the support sleeve.

[0018] Beneficial effect: The anti-slip layer can play an anti-slip role.

[0019] In another preferred embodiment of the present invention, a plurality of anti-slip protrusions are provided at the bottom of the anti-slip layer.

[0020] Beneficial effect: The anti-slip protrusions can increase the anti-slip effect.

[0021] In another preferred embodiment of the present invention, a notch is provided on the support sleeve close to the auxiliary block, and the notch is arranged on a side close to the auxiliary block.

[0022] Beneficial effect: the notch can be set to facilitate the tilting of the support frame, so that the roller can contact the ground and move the device.

[0023] In another preferred embodiment of the present invention, a support plate is arranged between the two support frames.

[0024] Beneficial effects: The support board can facilitate patients to sit down and take a rest during training and rehabilitation training.

[0025] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0034] The utility model provides a lower limb training auxiliary support device, such as Figure 1 As shown, in a preferred embodiment of the utility model, it includes two U-shaped support frames 1, the openings of the support frames 1 are arranged downward, and the two support frames 1 are arranged in parallel. A connecting rod 2 is provided between the two support frames 1, which is used to connect the two support frames 1 so that the two support frames 1 remain stable. In order to further enhance the stabilizing effect, two reinforcing rods 3 are provided between the two vertical parts of each support frame 1, and the two reinforcing rods 3 on each support frame 1 are cross-arranged. A support plate 4 is also provided between the upper parts of the two support frames 1, which can facilitate patients to sit down and rest.

[0035] The bottom of the support frame 1 is provided with a support sleeve 5, the longitudinal section of the support sleeve 5 is conical, and the large diameter end is the bottom end. The bottom of the support sleeve 5 is provided with an anti-skid layer 6, which is a rubber block, and the bottom of the anti-skid layer 6 is provided with a plurality of protrusions, which can play an anti-skid role, thereby improving the stability of the auxiliary support device when in use.

[0036] Combination Figure 2 As shown, the left side of the left support sleeve 5 is provided with a notch, so that the support frame 1 can be easily tilted up and off the ground.

[0037] An auxiliary block 7 is fixed to the lower left side of the support frame 1, and a groove 8 is provided at the bottom of the auxiliary block 7. A roller 9 is provided in the groove 8. The bottom of the roller 9 passes through the groove 8 and extends to the outside of the support frame 1, and the bottom of the roller 9 is flush with the bottom of the support sleeve 5. A rotating shaft 10 is coaxially fixed to the roller 9, and both ends of the rotating shaft 10 are rotatably connected to the auxiliary block 7.

[0038] Limiting blocks 11 are fixed on both sides of the roller 9 on the rotating shaft 10, and two blocks 12 are provided on the top of the groove 8. The two blocks 12 are respectively located on both sides of the roller 9, and the limiting blocks 11 are in contact with the right side of the block 12. Therefore, when the support frame 1 needs to move to the right, the roller 9 rotates clockwise to drive the support frame 1 to move to the right, and the rotating shaft 10 rotates synchronously with the roller 9, which can make the limiting block 11 gradually move away from the block 12 until the rotating shaft 10 rotates to the limit block 11 and the left side of the block 12 are in contact. At this time, the limiting block 11 is restricted by the block 12, so the rotating shaft 10 cannot continue to rotate, and the moving distance of the support frame 1 each time can be limited; and in order to control the distance of each movement, the diameter of the roller 9 can be set accordingly. The outer periphery of the block 12 and the limiting block 11 is provided with a buffer layer, and the buffer layer in this embodiment uses a rubber block.

[0039] Torsion springs 13 are sleeved on both sides of the rotating shaft 10 and the roller 9 , and the two ends of the torsion spring 13 are respectively fixed on the rotating shaft 10 and the auxiliary block 7 ; the specific model of the torsion spring 13 is selected according to actual needs.

[0040] The specific implementation process is as follows:

[0041] The patient's hands are placed on the top of the two support frames 1 and supported by the support frames 1. When the patient needs to walk forward, Figure 3 As shown, the right side of the support frame 1 is tilted up, so that the roller 9 is pressed against the ground, and the support frame 1 is pushed to the right. At this time, the roller 9 rotates clockwise. When the roller 9 rotates to the left side of the limit block 11 and the stopper 12, the roller 9 can no longer rotate clockwise, and the right side of the support frame 1 is dropped, and the patient is stably supported. The patient then moves to the right to complete the walking. During the whole process, the support frame 1 can support the patient to prevent excessive stress on the patient's lower limbs.

[0042] When training to the later stage, the patient's hands hold the tops of the two support frames 1, lift the support frames 1, move to the right, and then move the lower limbs to the right to complete the walking training. During the training process, when the patient is tired, he can sit on the support board 4 to rest.
