Description

Technical Field

[0001] This utility model belongs to the field of measuring tool technology, specifically relating to a portable adjustable progressive channel measuring ruler. Background Technology

[0002] When fitting eyeglasses, accurately measuring and determining the length of the "progressive path" is crucial, as it directly affects the wearer's visual comfort. Currently, optometrists mostly use traditional pupil pens or single rulers for estimation and measurement, a cumbersome process that relies on personal experience. Existing tools cannot quickly and accurately adapt to different face shapes and usage needs (such as preferences for distance, intermediate, and near vision), leading to measurement data deviations. This, in turn, results in improper eyeglass manufacturing, causing adaptation problems such as dizziness, blurred vision, and the need for excessive head adjustments, severely impacting the success rate of progressive lens fitting and the user experience.

[0003] Therefore, a portable adjustable progressive channel measuring ruler is proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Implementation

[0027] Please see Figure 1 -4, A portable adjustable progressive channel measuring ruler, comprising: a main scale 1 and a vernier scale 2;

[0028] The main scale 1 has a sliding connecting unit inside, which is used to connect the main scale 1 and the vernier scale 2 together;

[0029] The external sliding of the vernier scale 2 is equipped with a cursor positioning unit for accurately positioning the progressive channel;

[0030] The cursor positioning unit includes a sliding frame 3, an identification hole 4, a marker arrow 5, and a marker ring 6. The sliding frame 3 is slidably disposed outside the vernier ruler 2. The identification hole 4 is opened inside the sliding frame 3 and passes through one side of the sliding frame 3. The marker arrow 5 is fixedly disposed inside the identification hole 4, and the marker ring 6 is fixedly installed on one side of the sliding frame 3.

[0031] Furthermore, the connecting unit includes a slide groove 7, a slider 8, a limiting hole 9, a magnet 10, a movable groove 11, a compression spring 12, a limiting pin 13, and a connector 14. The slide groove 7 is opened inside the main scale 1, and the slider 8 is slidably disposed inside the main scale 1 through the slide groove 7. The limiting hole 9 is opened on the side of the slider 8 near the vernier scale 2, and the magnet 10 is fixedly installed inside the limiting hole 9. The movable groove 11 is opened on the side of the vernier scale 2 near the slider 8, and the compression spring 12 is fixedly installed inside the movable groove 11. The limiting pin 13 is slidably disposed inside the movable groove 11 through the compression spring 12. The connector 14 is fixedly installed on the slider 8, and the vernier scale 2 is rotatably disposed on one side of the slider 8 through the connector 14.

[0032] Specifically, the vernier scale 2 is rotated and set on one side of the slider 8 through the connector 14. When it is necessary to fold up the measuring scale, the slider 8 can be slid to the center position of the main scale 1 through the slide groove 7, and then the vernier scale 2 can be rotated through the connector 14 to make the vernier scale 2 parallel to the main scale 1, thereby folding up the measuring scale.

[0033] Furthermore, the bottom edge of the main ruler 1 has a left pupil distance notch 15, a nose bridge notch 16, and a right pupil distance notch 17, and the left pupil distance notch 15 and the right pupil distance notch 17 are positioned opposite each other on both sides of the nose bridge notch 16.

[0034] Specifically, by setting the left pupillary distance notch 15 and the right pupillary distance notch 17 opposite each other on both sides of the nasal bridge notch 16, the aesthetics of the main ruler 1 are maintained, and the patient's pupillary distance can also be detected through the left pupillary distance notch 15 and the right pupillary distance notch 17.

[0035] Furthermore, a special scale for measuring pupillary distance is provided on one side of the main scale 1, and the special scale for measuring pupillary distance is located above the left pupillary distance notch 15 and the right pupillary distance notch 17.

[0036] Specifically, by setting the dedicated scale for measuring pupillary distance above the left pupillary distance notch 15 and the right pupillary distance notch 17, the data can be made more accurate when measuring pupillary distance.

[0037] Furthermore, one end of the limiting pin 13 is tapered, and the outer diameter of the limiting pin 13 is smaller than the inner diameter of the limiting hole 9.

[0038] Specifically, by making the outer diameter of the limiting pin 13 smaller than the inner diameter of the limiting hole 9, the limiting pin 13 can be inserted into the limiting hole 9, and then the magnet 10 can hold the limiting pin 13 in place, thereby fixing the vernier caliper 2.

[0039] Furthermore, both the main scale 1 and the vernier scale 2 are made of tough PVC material, and the length of the main scale 1 is longer than the height of the vernier scale 2.

[0040] Specifically, the main scale 1 and vernier scale 2, made of PVC material, are lightweight, easy to carry, and convenient to use anytime.

[0041] Furthermore, the marking ring 6 is made of thermoplastic plastic filament, and the inner diameter of the marking ring 6 is two millimeters.

[0042] Specifically, by setting the inner diameter of the marking ring 6 to two millimeters, errors can be reduced, making the marking position of the marking ring 6 more accurate.

[0043] Furthermore, both ends of the main scale 1 and both ends of the vernier scale 2 are provided with locking devices 18, which are made of rubber.

[0044] Specifically, the clip 18, made of rubber, can cover the edges of the main scale 1 and the vernier scale 2 to prevent the edges of the main scale 1 and the vernier scale 2 from scratching patients and staff during measurement.

[0045] Furthermore, the dimensions of the card 18 are larger than the dimensions of the slider 8.

[0046] Specifically, by setting the size of the clip 18 to be larger than the size of the slider 8, it can be prevented that the slider 8 will slide out of the main scale 1 when sliding.

[0047] Furthermore, the magnet 10 is made of neodymium magnet, and the magnet 10 is fixedly installed inside the limiting hole 9 by adhesive.

[0048] Specifically, by gluing a neodymium magnet 10 inside the limiting hole 9, the attraction between the magnet 10 and the limiting pin 13 can be increased, so that the limiting pin 13 is firmly attached to the inside of the limiting hole 9, thereby restricting the rotation of the vernier caliper 2.

[0049] The technical solution provided in this embodiment is as follows: When in use, the interpupillary distance can be measured through the left interpupillary distance notch 15 and the right interpupillary distance notch 17. When measuring the length of the progressive channel, first align the scale line on the main ruler 1 with the customer's eyes and pupils, then move the vernier caliper 2 through the slide groove 7 and the slider 8 to mark the length of the customer's progressive channel, then slide the sliding frame 3 on the vernier caliper 2, mark the end point of the progressive channel through the marking ring 6, and then draw a mark inside the marking ring 6 with a pen. The length of the progressive channel can be marked on the glasses.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
