Description
Technical Field
[0001] This utility model relates to the field of visual training technology, and more specifically, to a foldable multifunctional extraocular muscle and ciliary muscle synergistic training ruler. Background Technology
[0002] Medical research shows that prolonged close-range eye use leads to excessive strain on the ciliary muscle, decreased lens accommodation ability, and abnormal elongation of the eye axis, increasing the risk of myopia. In the field of vision care, the function of the extraocular muscles and ciliary muscles is crucial for visual health. Traditional eye muscle training methods often suffer from problems such as limited functionality, poor portability, and insufficient training enjoyment, making it difficult to meet the diverse vision training needs of different groups, especially in terms of convenient and efficient eye movement and ciliary muscle accommodation training.
[0003] Traditional vision training methods, such as the Bates Method, relax the ciliary muscle by dynamically focusing on images, but with minimal effect. While supplementary acupressure massage can relieve fatigue, it doesn't necessarily improve vision. Traditional ciliary muscle training methods, such as using ciliary muscle ropes, are inconvenient to carry and uninteresting.
[0004] Therefore, a foldable, multifunctional extraocular muscle and ciliary muscle synergistic training ruler is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a foldable multifunctional extraocular muscle and ciliary muscle synergistic training ruler to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable, multifunctional extraocular muscle and ciliary muscle synergistic training ruler, comprising:
[0007] V-shaped basic ruler body: Two rectangular ruler bodies are connected at the starting end by a damping hinge, and the opening and closing angle (0~180°) is adjustable and self-locking at any angle; a nose bridge clamping block is provided on the inner side of the starting end;
[0008] Folding extension ruler: The ends of the two rectangular rulers are connected to the folding extension ruler through damping pivots, and the opening angle (0~180°) is adjustable;
[0009] Limiting groove structure: Limiting grooves are opened on the upper surface of both rectangular rulers, and their dimensions match the cross-section of the folded extension ruler;
[0010] When the folding extension ruler is closed (0° state), its top surface is flush with the top surface of the rectangular ruler body; when the folding extension ruler is unfolded 180°, its bottom surface is flush with the bottom surface of the limiting groove.
[0011] Marking system: When the folding extension ruler is unfolded to 180°, circular marking areas with a spacing increasing geometrically by 1.2 times are continuously set from the starting position of the limiting groove to the end surface of the folding extension ruler; when the folding extension ruler is rotated 90° and stands vertically, square marking areas are set at the top and bottom of its bottom surface (the side facing the starting end).
[0012] Functional association: When both folded extension rulers are vertically erected, the four square marking areas form a rectangular tracking frame; the circular marking area is used to guide ciliary muscle accommodation training, and the square marking area is used to guide extraocular muscle tracking training; the unfolding angle of the V-shaped basic ruler is adjustable. When the folded extension ruler is vertically erected, by changing the unfolding angle of the basic ruler, the size of the rectangular tracking frame formed by the four square marking areas can be dynamically adjusted, thereby achieving visual span range expansion training.
[0013] Preferably, the nose bridge clamping block has a cross-sectional curvature radius of 8-12 mm and is provided with a clamping force adjustment structure.
[0014] Preferably, both the damping hinge and the damping shaft have an angle self-holding function.
[0015] Preferably, the depth of the limiting groove is equal to the thickness of the folding extension ruler, and when unfolded to 180°, the bottom surface of the limiting groove and the bottom surface of the folding extension ruler are coplanar to form a continuous plane.
[0016] Preferably, both the circular and square marking areas have built-in LED light sources, which are driven by the control module to light up and turn off according to a preset mode.
[0017] Preferably, the rectangular ruler body integrates a rechargeable battery and has a magnetic charging area at the starting end or on the surface of the folded extension ruler for wireless charging via an external magnetic charger.

[0025] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] like Figures 1-4 As shown, a foldable, multifunctional extraocular muscle and ciliary muscle synergistic training ruler includes:
[0028] V-shaped basic ruler body: Two rectangular ruler bodies 1 are connected at the starting end by a damping hinge 2. The opening and closing angle (0~180°) is adjustable and can be locked at any angle; a nose bridge clamping block 3 is provided on the inner side of the starting end.
[0029] Folding extension ruler: The ends of the two rectangular rulers 1 are connected to the folding extension ruler 4 via damping pivots 4a, and the opening and closing angle (0~180°) is adjustable.
[0030] Limiting groove structure: Limiting grooves 1a are opened on the upper surface of both rectangular rulers 1, and their dimensions match the cross section of the folded extension ruler 4.
[0031] When the folding extension ruler 4 is closed (0° state), its top surface is flush with the top surface of the rectangular ruler body 1; when the folding extension ruler 4 is unfolded 180°, its bottom surface is flush with the bottom surface of the limiting groove 1a.
[0032] Marking system: When the folding extension ruler 4 is unfolded to 180°, circular marking areas 5a are continuously set from the starting position of the limiting groove 1a to the end surface of the folding extension ruler 4 with a spacing that increases geometrically by 1.2 times; when the folding extension ruler 4 is rotated 90° and stands vertically, square marking areas 6a are set at the top and bottom of its bottom surface (the side facing the starting end).
[0033] Functional association: When both folded extension rulers 4 are vertically erected, the four square marking areas 6a form a rectangular tracking frame; the circular marking area 5a is used to guide ciliary muscle accommodation training, and the square marking areas 6a are used to guide extraocular muscle tracking training; the unfolding angle of the V-shaped basic ruler is adjustable. When the folded extension ruler 4 is vertically erected, by changing the unfolding angle of the basic ruler, the size of the rectangular tracking frame formed by the four square marking areas 6a can be dynamically adjusted, thereby realizing visual span range expansion training.
[0034] The training ruler consists of two rectangular ABS plastic rulers 1, each 21cm long, 3cm wide, and 2.5mm thick. The starting end is connected by a damping hinge 2 with a torque of 0.5N·m, enabling stepless opening and closing from 0 to 180°, with stable self-locking when opened to 120°. A nose bridge clamping block 3 is located inside the hinge and is molded from medical-grade silicone with a Shore A hardness of 40A, with a curvature radius of 10mm to fit the nose bridge of Asian individuals.
[0035] The folding extension ruler 4 is connected to the end of the rectangular ruler body 1 via a micro-damping pivot 4a. The pivot torque of 0.3 N·m ensures self-locking in a 90° vertical state. The limiting groove 1a is formed on the upper surface of the rectangular ruler body 1, with a depth of 2.5 mm and a width of 3 cm, and the same thickness as the folding extension ruler 4. When the folding extension ruler 4 is rotated 180° and unfolded horizontally, its bottom surface is precisely coplanar with the bottom surface of the limiting groove 1a, forming a continuous plane with a total length of 42 cm.
[0036] The laser-engraved circular marking area 5a on this plane: with the starting edge of the limiting groove 1a as the reference, the positions of the 5mm diameter rings are set at 1cm, 1.2cm, 1.44cm... to the end at a 1.2 times equal ratio. When the folded extension ruler 4 is vertical, a 10mm×10mm square marking area 6a is embedded in the top and bottom of its bottom surface near the user, with LED beads inside; when the two extension rulers are upright, the four square marking areas 6a form a 10cm×6cm rectangular optical tracking frame.
[0037] Users can simultaneously change the vertical distance between the two folded extension rulers 4 by expanding or contracting the V-shaped base ruler body at an angle (30°~180°):
[0038] Increase the angle: Increase the distance between the two folded extension rulers 4, and enlarge the size of the rectangular frame formed by the square marking area 6a to train the ability of large visual span eye saccades;
[0039] Adjusting the angle: The spacing of the folded extension ruler 4 is reduced, and the size of the rectangular frame is decreased, thus training high-precision focusing and tracking capabilities.
[0040] The damping hinge (2) is self-locking at any angle to ensure that the frame size is stable and does not deform during training.
[0041] Example 2
[0042] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:
[0043] According to the appendix Figures 1-4 As shown, the nose bridge clamping block 3 has a cross-sectional curvature radius of 8-12mm and is equipped with a clamping force adjustment structure. Furthermore, the clamping force adjustment of the nose bridge clamping block 3 is achieved by squeezing to drive the arc-shaped silicone wings to unfold / fold, with an adaptation range corresponding to a nose bridge width of 34-42mm.
[0044] In this embodiment, both the damping hinge 2 and the damping shaft 4a have an angle self-locking function. Furthermore, the damping hinge 2 adopts a metallurgical gear meshing structure with a damping torque of 0.5±0.1 N·m; the damping shaft 4a is a polymer composite friction plate type with a torque of 0.3±0.05 N·m. Both automatically trigger self-locking when the rotation angle is >5°, and an external force >1N is required to unlock, ensuring no accidental displacement during training.
[0045] In this embodiment, the depth of the limiting groove 1a is equal to the thickness of the folding extension ruler 4. When unfolded 180°, the bottom surface of the limiting groove 1a and the bottom surface of the folding extension ruler 4 are coplanar, forming a continuous plane. Furthermore, the depth tolerance of the limiting groove 1a is controlled within ±0.05mm, and the flatness of the bottom surface of the folding extension ruler 4 is ≤0.1mm. When unfolded 180°, the height difference between the bottom surface of the limiting groove 1a and the bottom surface of the folding extension ruler 4 is measured to be <0.05mm using a laser interferometer, forming an optically grade continuous plane and avoiding visual focal length jumps.
[0046] In this embodiment, both the circular marking area 5a and the square marking area 6a have built-in LED light sources, which are driven by the control module to turn on and off according to a preset mode. Furthermore, the circular marking area 5a uses a PMMA cover to encapsulate the LED, which is driven by an STM32F030 microcontroller.
[0047] Ciliary muscle mode: LEDs light up and turn off in a 1.2n interval sequence (n = 0 → 5 → 0), with a lighting duration of 1.5s and an interval of 0.3s.
[0048] In extraocular muscle mode, the four lights in the square marking area 6a change in 50ms increments along a preset path, such as an "∞" shape, with an equivalent eye movement speed of 5cm / s.
[0049] In this embodiment, a rechargeable battery is integrated inside the rectangular ruler 1, and a magnetic charging area 8 is provided on the starting end or the surface of the folded extension ruler 4 for wireless charging via an external magnetic charger. Furthermore, the rechargeable battery is a 3.7V / 500mAh lithium polymer battery, integrated into the internal cavity of the rectangular ruler 1. The magnetic charging area 8 contains a neodymium iron boron magnetic ring with a magnetic attraction force >3N and copper charging contacts. It automatically attracts the external charger when it approaches.
[0050] The working process of this utility model is as follows:
[0051] Step 1: Deploying and Wearing the Device
[0052] The user holds the two rectangular rulers 1 in their closed state and pushes the base of the rulers outward with their thumb. The damping hinge 2 provides uniform resistance, allowing the rulers to remain stably at a preset angle, such as 120°, forming a stable V-shaped structure. Then, the nose bridge clamping block 3 at the starting end is placed against the nose bridge, and the clamping force is finely adjusted through the sliding groove until there is no looseness.
[0053] Step 2: Mode Selection and Component Deployment
[0054] Ciliary muscle training mode:
[0055] Pinch the end of the folded extension ruler 4 and rotate it 180° around the damping pivot 4a until it is horizontal. At this point, the bottom surface of the folded extension ruler 4 is precisely embedded in the limiting groove 1a, and the bottom surfaces of the two are completely coplanar, forming a continuous training plane from the nose bridge clamping block 3 to the end of the ruler. The circular marking area 5a, marked with a geometric sequence, is distributed across the limiting groove 1a and the surface of the folded extension ruler 4 at intervals of 1.2 times: 1cm → 1.2cm → 1.44cm…
[0056] Extraocular muscle training mode:
[0057] Rotate the folding extension ruler 4 90° around the damping pivot 4a until it is vertical, and fix it to the table with the bottom magnetic plate. The square marking areas 6a of the two folding extension rulers 4 form a 10cm × 6cm rectangular tracking frame in space.
[0058] Step 3: Perform the training
[0059] Ciliary muscle dynamic focusing:
[0060] A short press of the button activates the light, illuminating the nearest circular marker area (LED 5a) in red. After the user focuses on this point for 2 seconds, the light jumps to the next distant marker in a proportional sequence with 1.5-second intervals. After completing 5 cycles of "near → far → near," the light automatically switches to blue for reverse training of far → near → far.
[0061] Extraocular muscle tracking training:
[0062] When the "∞-shaped mode" is selected, the upper left square marker area 6a lights up green, and the user's eye tracks to this point; after 0.8 seconds, the light jumps to the lower right point, then sequentially jumps to the upper right and lower left points, forming a closed-loop dynamic path. The speed increases from 2cm / s to 8cm / s as the user's proficiency improves.
[0063] Step 4: Charging and Maintenance
[0064] After training, align the magnetic charger with the hidden magnetic charging area 8 at the starting end. After automatic magnetic attraction, the charging indicator light will glow red; it will turn green after 2 hours when fully charged. No plugging or unplugging is required throughout the process, preventing interface wear.
[0065] Step 5: Efficient Storage
[0066] Pinch the folded extension ruler 4 and gently lift it upwards to release it from the magnetic attraction. Rotate it to the 0° closed state, where its surface is flush with the limiting groove 1a. Press the two rectangular rulers 1 together with both hands to close them around the damping hinge 2, compressing the whole into a flat shape of 21cm×3cm×1.5cm. Place it in the carrying bag.
