Abstract

The invention relates to the field of vision recovery devices, in particular to an extraocular muscle training device for vision rehabilitation. The device comprises a base, a supporting column, a shielding plate, a swing arm, a reciprocating swing driving assembly, a thin rod, a fastening assembly and a swing ball. The device has the beneficial effects that a patient stands or sits in front of the shielding plate, the reciprocating swing driving assembly drives the swing arm to swing in a reciprocating mode, the swing ball swings in a reciprocating mode, the eyeballs of the patient watch theswing ball and swing along with swinging of the swing ball, and therefore the extraocular muscles are exercised; compared with a mode that green vegetation is watched for training recovery in the prior art, the device has the advantages that the training effect is improved to a certain extent, the training efficiency is improved, and the training progress is accelerated; and the thin rod is hingedto the swing arm and is limited to rotate along the hinged position of the thin rod and the swing arm through the fastening assembly, so that the distance between the swing ball and the patient can be adjusted, and the practicality is improved.

Example Embodiment

[0022]Example
[0023]Such asFigure 1-4As shown, an extraocular muscle training device for vision rehabilitation includes a base 1 detachably installed on a placement surface, a support column 2 is vertically provided on the base 1, and a shield is provided at the upper end of the support column 2 18. A swing arm 7 is connected to one side of the shutter 18 through a mounting shaft for horizontal rotation. The swing arm 7 is driven to reciprocate by a reciprocating swing drive assembly. The upper end of the swing arm 7 is hinged with a thin rod 9, which 9 is restricted from rotating along the hinge joint with the swing arm 7 by a fastening component, the top end of which protrudes above the shutter 18 and a swing ball 10 is provided.
[0024]As a further optimization of the above technical solution, the upper end of the support column 2 is rotatably sleeved with a rotating sleeve 4, the rotating sleeve 4 is provided with a threaded rod 16 through coaxial threads, and the support column 2 is provided with The through hole through which the threaded rod 16 passes freely, the shutter 18 is fixed on the upper end of the threaded rod 16, and when the rotating sleeve 4 rotates on the supporting column 2, the threaded rod 16 is driven to move vertically.
[0025]As a further optimization of the above-mentioned technical solution, the top end of the support column 2 is provided with an annular protrusion 14 coaxially, the rotating sleeve 4 is slidably mounted on the annular protrusion 14, and the upper end is fitted with For the pin 3, correspondingly, the circumferential surface of the annular protrusion 14 is coaxially provided with an annular groove 15 for inserting the pin 3 into the rotating sleeve 4 and capable of rotating at one end.
[0026]As a further optimization of the above technical solution, a plurality of anti-slip patterns are provided on the peripheral surface of the rotating sleeve 4.
[0027]As a further optimization of the above-mentioned technical solution, the inner hole of the annular protrusion 14 is provided with several key bars. Correspondingly, the threaded rod 16 is provided with a threaded rod that cooperates with the key bar and is used to restrict the threaded rod. 16 is a keyway 17 that rotates in the circumferential direction on the annular projection 14.
[0028]As a further optimization of the above technical solution, the fastening assembly includes a U-shaped notch provided at the upper end of the swing arm 7, a fixed ring is provided at the lower end of the thin rod 9, and the fixed ring is hinged on the U-shaped by a mounting bolt 8 In the gap, and the bolt 8 is threaded through the swing arm 7. When the bolt 8 is screwed on the swing arm 7, the two inner side walls of the U-shaped gap are driven to approach each other and press against the The two end faces of the fixed ring allow the fixed ring to restrict rotation.
[0029]As a further optimization of the above-mentioned technical solution, the reciprocating swing drive assembly includes a driven gear 11 provided on the swing arm 7. The axis of the driven gear 11 and the rotation axis of the swing arm 7 on the shutter 18 Coaxially, a servo motor 6 is installed on the shield 18 through a bracket, and a first sector gear 5 and a second sector gear 13 are drivingly connected to the servo motor 6, the first sector gear 5 and the second sector gear 13 are gear structures with teeth on a part of the peripheral surface, and the teeth on the two peripheral surfaces correspond to each other. The shield 18 is rotatably connected with an intermediate gear 12 meshing with the driven gear 11 through a mounting shaft. When the servo motor 6 rotates, the first sector gear 5 and the second sector gear 13 are driven to alternately mesh with the driven gear 11 and the intermediate gear 12, so that the driven gear 11 can reciprocate.
[0030]The principle and advantages of the present invention: when adjusting the height of the shutter 18, first manually rotate the rotating sleeve 4, and the rotating sleeve 4 rotates on the supporting column 2, and at the same time, the threaded rod 16 is screwed with the rotating sleeve 4 to drive the threaded rod 16 vertically. Move straight to adjust the height of the shutter 18 to adapt to patients with different heights;
[0031]When working, first turn on the external power supply and start the servo motor 6. The servo motor 6 drives the first sector gear 5 and the second sector gear 13 to mesh with the driven gear 11 and the intermediate gear 12 alternately. Because the intermediate gear 12 and the driven gear 11 is also in the meshing state, so that when the first sector gear 5 meshes with the driven gear 11, the intermediate gear 12 does not mesh with the teeth on the second sector gear 13, and the driven gear 11 is in the forward rotation state. When a sector gear 5 is disengaged from the driven gear 11 for meshing transmission, the second sector gear 13 is in contact with the intermediate gear 12 and is meshed for transmission, and then drives the driven gear 11 to rotate in the reverse direction, so that the swing arm 7 can reciprocate;
[0032]The patient's eyeballs follow the swinging ball 10 to swing, thereby exercising the extraocular muscles. Of course, in order to improve the exercise effect, the surface of the swinging ball can be coated with a green coating, which is more eye-catching and the eyeball following effect is better.
