Description

Technical Field

[0001] This utility model relates to the field of vision correction technology, and in particular to a multifunctional eye muscle training device. Background Technology

[0002] With the surge in electronic screen usage and the trend of myopia affecting younger people, eye muscle training devices, as an active visual health management tool, are gradually becoming an important means of relieving eye fatigue and improving accommodative functions (such as accommodative sensitivity and convergence function).

[0003] In existing technologies, existing eye muscle training devices light up different LEDs in sequence while the user's head remains still. The user's eye movements track the LEDs in real time, thereby training the muscles around the eyes, such as the ciliary muscle. However, the existing training devices are in a fixed position relative to the user, resulting in relatively weak training of the eye's lens. Therefore, a multifunctional eye muscle training device was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional eye muscle training device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional eye muscle training device includes a base with an internal mounting cavity. A rectangular frame is fixedly embedded on one side of the top of the base. A square hole adapted to the rectangular frame is opened on the top of the base. Two guide rods are fixedly connected between the two ends of the rectangular frame. A slider is slidably fitted on the circumferential surface of the two guide rods. Both ends of the slider have round holes adapted to the guide rods. A motor is fixedly connected to the top of the base near the rectangular frame. A rotating rod is fixedly connected to the bottom output end of the motor through the base. A strip-shaped hole is opened on the rotating rod. A round rod is fixedly connected to both ends of the strip-shaped hole. A sliding block is slidably fitted on the round rod. A round hole adapted to the round rod is opened on the sliding block. A connecting rod is rotatably connected to the top of the sliding block. The other end of the connecting rod is rotatably connected to the bottom of the slider. The rotation of the rotating rod drives the movement of the connecting rod, causing the rectangular frame to move back and forth with the training device body. An adjustment mechanism is provided at the bottom of the base near the rotating rod.

[0007] Preferably, the adjustment mechanism includes two fixed rods fixedly connected to the bottom of the mounting cavity. The top of the two fixed rods is fixedly connected to the same limiting plate. The circumferential surface of the two fixed rods is slidably fitted with the same cylinder. Both sides of the cylinder are provided with circular holes adapted to the fixed rods. A lead screw is rotatably connected to the middle of the bottom of the limiting plate, and the bottom of the lead screw is threaded through the cylinder. A lead screw nut adapted to the lead screw is fixedly fitted in the middle of the cylinder. The bottom of the lead screw is fixedly connected to a knob through the bottom of the base. An arc-shaped groove is provided on the outer circumference of the cylinder, and a ring is slidably connected in the arc-shaped groove. A pull rod is rotatably connected to one side of the outer wall of the ring, and the other end of the pull rod is rotatably connected to the bottom of the sliding block. The adjustment mechanism facilitates the adjustment of the range of reciprocating movement of the slider.

[0008] Preferably, a vertical plate is fixedly connected to the top of the rectangular frame, vertical holes are provided on both sides of the vertical plate, and a serrated rack is fixedly embedded in the middle of the vertical plate, and a hole adapted to the serrated rack is provided in the middle of the vertical plate.

[0009] Preferably, a vertical rod is fixedly connected between the top and bottom of each of the two vertical holes, a rectangular block is slidably fitted on each of the two vertical rods, a round hole adapted to the vertical rod is opened on each of the two rectangular blocks, and the same training instrument body is fixedly connected to the side of the two rectangular blocks away from the motor.

[0010] Preferably, a plurality of LED beads are arranged on the side of the training device body away from the motor, and a main board for controlling the LED beads is arranged inside the training device body, and a control board is arranged on one side of the outer wall of the training device body, and the main board is electrically connected to the control board and the LED beads respectively.

[0011] Preferably, a U-shaped rod is fixedly connected to the bottom center of the training device body near the vertical plate, and an L-shaped inclined block is slidably sleeved in the middle of the U-shaped rod. The L-shaped inclined block is adapted to the inclined rack. Both ends of the L-shaped inclined block are provided with round holes adapted to the U-shaped rod. Both ends of the U-shaped rod near the training device body are sleeved with springs. The height of the training device body can be easily adjusted through the cooperation of the L-shaped inclined block, the spring and the inclined rack.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By employing technologies such as sliders, guide rods, rotating rods, sliding blocks, lead screws, cylinders, rings, and pull rods, the slider moves back and forth with the training device body through the rotation of the motor, adjusting the distance between the training device body and the user's eyes. The rotation of the lead screw adjusts the range of the slider's back and forth movement with the training device body. This effectively solves the problem of weak training of the eye lens mentioned in the background technology, thereby enabling the distance between the training device body and the eyes to continuously change, simulating the scenario of looking at near and far objects. The eye lens needs to continuously adjust its thickness, strengthening the ciliary muscle's control over the lens, and improving the quality of eye training in conjunction with the training device body.

[0014] 2. By incorporating L-shaped inclined blocks, springs, and inclined racks, the height of the training device can be adjusted in real time according to the user's height or sitting posture, thus improving its practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-5 A multifunctional eye muscle training device includes a base 1 with an internal mounting cavity. A rectangular frame 2 is fixedly embedded on one side of the top of the base 1. A square hole adapted to the rectangular frame 2 is opened on the top of the base 1. Two guide rods 501 are fixedly connected between the two ends of the rectangular frame 2. The same slider 5 is slidably fitted on the circumferential surface of the two guide rods 501. Both ends of the slider 5 are provided with round holes adapted to the guide rods 501. A motor 4 is fixedly connected to the top of the base 1 near the rectangular frame 2. The bottom output end of the motor 4 passes through the base 1 and is fixedly connected to a rotating rod 401. A strip hole is opened on the rotating rod 401. The two ends of the strip hole are fixedly connected to the same round rod 403. A sliding block 402 is slidably fitted on the round rod 403. A round hole adapted to the round rod 403 is opened on the sliding block 402. A connecting rod 502 is rotatably connected to the top of the sliding block 402. The other end of the connecting rod 502 is rotatably connected to the bottom of the slider 5. An adjustment mechanism is provided at the bottom of the base 1 near the rotating rod 401.

[0023] In this utility model, the adjustment mechanism includes two fixed rods 6 fixedly connected to the bottom of the mounting cavity. The top of the two fixed rods 6 is fixedly connected to the same limiting plate. The same cylinder 603 is slidably sleeved on the circumferential surface of the two fixed rods 6. The cylinder 603 has round holes on both sides that are adapted to the fixed rods 6. A lead screw 601 is rotatably connected to the middle of the bottom of the limiting plate. The bottom of the lead screw 601 is threaded through the cylinder 603. A lead screw nut adapted to the lead screw 601 is fixedly sleeved in the middle of the cylinder 603. A knob 602 is fixedly connected to the bottom of the base 1 through the bottom of the lead screw 601. An arc groove is opened on the outer circumferential surface of the cylinder 603. A ring 604 is slidably connected in the arc groove. A pull rod 404 is rotatably connected to one side of the outer wall of the ring 604. The other end of the pull rod 404 is rotatably connected to the bottom of the sliding block 402.

[0024] In this utility model, a vertical plate 7 is fixedly connected to the top of the rectangular frame 2. Vertical holes 701 are provided on both sides of the vertical plate 7, and a helical rack 702 is fixedly embedded in the middle of the vertical plate 7. A hole adapted to the helical rack 702 is provided in the middle of the vertical plate 7.

[0025] In this utility model, vertical rods 302 are fixedly connected between the top and bottom of the two vertical holes 701. Rectangular blocks 301 are slidably sleeved on the two vertical rods 302. The two rectangular blocks 301 are provided with round holes that are adapted to the vertical rods 302. The same training instrument body 3 is fixedly connected to the side of the two rectangular blocks 301 away from the motor 4.

[0026] As can be seen from the above description, the first embodiment of this utility model achieves the following technical effects: by moving the slider 2 back and forth with the motor 4, the distance between the training device body 3 and the eyes can be adjusted in real time, thereby improving the quality of eye training. At the same time, the setting of the adjustment mechanism makes it easy to change the range of the slider 2's back and forth movement, making it easy to adjust and further improving the quality and requirements of eye training.

[0027] Example 2: The difference from Example 1 is that multiple LED beads are arranged on the side of the training device body 3 away from the motor 4, and a main board for controlling the LED beads is arranged inside the training device body 3. A control board is arranged on one side of the outer wall of the training device body 3, and the main board is electrically connected to the control board and the LED beads respectively.

[0028] In this utility model, a U-shaped rod 303 is fixedly connected to the middle of the bottom of the training instrument body 3 near the vertical plate 7, and an L-shaped inclined block 304 is slidably sleeved in the middle of the U-shaped rod 303. The L-shaped inclined block 304 is adapted to the inclined rack 702. Both ends of the L-shaped inclined block 304 are provided with round holes adapted to the U-shaped rod 303. Springs 305 are sleeved at both ends of the U-shaped rod 303 near the training instrument body 3.

[0029] As can be seen from the above description, the second embodiment of this utility model achieves the following technical effects: through the cooperation of the L-shaped inclined block 304, the spring 305, and the inclined rack 702, when adjusting the height of the training device body 3, pressing the L-shaped inclined block 304 separates it from the inclined rack 702, allowing the training device body 3 to be moved to a suitable position. After releasing the L-shaped inclined block 304, the L-shaped inclined block 304 engages with the inclined rack 702, thus fixing the training device body 3. This facilitates quick adjustment for users of different heights or sitting postures, making it convenient to use.

[0030] Working Principle: When using this device, the training instrument body 3 uses existing technology. Multiple LEDs are controlled by the main board to light up sequentially. The user's head remains stationary; instead, the eyeballs move to track the lit LEDs, thus exercising eye muscles such as the ciliary muscle. To adjust the distance between the training instrument body 3 and the user's eyes during operation, allowing the lens to adapt and improve training effectiveness, the motor 4 is activated. This drives the rotating rod 401, which in turn moves the connecting rod 502, causing the slider 2 to reciprocate with the training instrument body 3. This ensures that while the user is training, the distance between the training instrument body 3 and the eyes is constantly changing, enhancing training quality. Furthermore, to adjust the range of reciprocating movement of the training instrument body 3, the knob 602 is rotated, changing the position of the cylinder 603 and the ring 604. This causes the pull rod 404 to pull the sliding block 402 along the rod 403. This changes the distance between the connecting rod 502 and the output shaft of the motor 4, thereby adjusting the reciprocating range of the slider 2 when the motor 4 rotates with the rotating rod 401. At the same time, when the motor 4 rotates with the pull rod 404, the pull rod 404 rotates outside the cylinder 603 through the ring 604, without interfering with the adjustment mechanism. When it is necessary to adjust the height of the training device body 3, pressing the L-shaped inclined block 304 separates the L-shaped inclined block 304 from the inclined rack 702, allowing the training device body 3 to slide up and down along the vertical rod 302. Releasing the L-shaped inclined block 304 prevents the training device body 3 from descending, making it easy to adjust the height of the training device body 3.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
