Description

Technical Field

[0001] This invention relates to a progressive multifocal lens fitting experience frame, belonging to the field of lens fitting technology. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After being polished, they are often assembled with eyeglass frames to form eyeglasses, used to correct the user's vision and obtain a clear field of vision.

[0003] Before wearing glasses, we need to have our eyes examined. However, current eye exams involve adding lenses to the frame multiple times, which is bulky and provides only average clarity. Also, the eye exam requires wearing two or more lenses at the same time, which can cause a significant discrepancy between the experience and the actual glasses fit. Furthermore, the pupillary distance cannot be adjusted during the eye exam, and even if it can be adjusted, the adjustment accuracy is poor, the adjustment range is small, and the durability is low, making it unsuitable for long-term use.

[0004] In view of the above-mentioned shortcomings, the present invention aims to create a progressive multifocal lens fitting experience frame, making it more valuable for industrial applications. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this invention is to provide a progressive multifocal lens fitting experience frame.

[0006] The present invention provides a progressive multifocal lens fitting experience frame, including a pupillary distance adjustment mechanism for adjusting the pupillary distance corresponding to the fitting frames on both sides of the entire fitting experience frame. Two fitting frames are symmetrically fixedly welded on both sides of the pupillary distance adjustment mechanism for installing lenses of different powers. A clamping mechanism is also connected in the middle of the pupillary distance adjustment mechanism for clamping the entire fitting experience frame onto the glasses of the fitting person.

[0007] The interpupillary distance adjustment mechanism includes an intermediate layer sandwiched in the middle. The upper and lower surfaces of the intermediate layer are respectively provided with a metal cover plate and an interpupillary distance marking base plate. The intermediate layer, the interpupillary distance marking base plate, and the metal cover plate are fixedly connected as a whole by locking screws.

[0008] Furthermore, the interpupillary distance adjustment mechanism includes an adjustment metal plate and two slidable adjustment levers embedded therein. A positioning steel ball is also provided between the adjustment metal plate and the adjustment levers. The positioning steel ball realizes the smoothness and damping feel of the adjustment process of the adjustment levers, so that the interpupillary distance can be accurately adjusted. The geometric interpupillary distance that the interpupillary distance adjustment mechanism can adjust is 58-70mm.

[0009] Furthermore, the adjusting metal plate has a rectangular plate structure. Two adjusting metal plate fixing holes are symmetrically provided at both ends of the upper half of the adjusting metal plate for mounting locking screws. The upper half of the adjusting metal plate also has two downward-pressing spring tabs symmetrically arranged on the left and right sides. The ends of the spring tabs have concave semi-circular steel ball grooves for accommodating the steel balls. The lower half of the adjusting metal plate also has two upward-pressing limiting rods symmetrically arranged on the left and right sides. The ends of the limiting rods have limiting hooks to prevent the adjusting tabs from sliding outwards. A rectangular tab groove is formed between the spring tabs and the limiting rods for installing the adjusting tabs. The middle of the lower half of the adjusting metal plate also has two rectangular adjusting metal plate locking holes symmetrically arranged for installing a clamping mechanism.

[0010] The first end of the adjustment lever is provided with a rectangular gear position display slot for observing and displaying the gear position value of the adjustment lever. A wave-shaped steel ball placement groove is provided at the edge of the adjustment lever near the drop spring. The steel ball placement groove and the steel ball groove are matched and set. There are a total of 6 steel ball placement grooves, corresponding to the six interpupillary distances.

[0011] Furthermore, the interpupillary distance indicator base plate has symmetrically engraved 7 numbers from 0 to 6, corresponding to different interpupillary distance settings; the metal cover plate has symmetrically provided metal cover plate fixing holes at both ends, which are matched with the fixing holes of the adjusting metal plate for mounting locking screws; two position display windows are symmetrically provided in the middle of the metal cover plate, which are matched with the numerical positions engraved on the interpupillary distance indicator base plate for displaying the position of the adjusting lever; and two rectangular metal cover plate locking holes are symmetrically provided in the middle of the bottom of the metal cover plate for matching and installing clamping mechanisms.

[0012] Furthermore, the clamping mechanism includes a clamping fixing component and a clamping driving component, and the clamping fixing component and the clamping driving component are elastically connected through a clamping connector, a spring mounting component and a clamping spring;

[0013] The clamping and fixing component has two locking heads symmetrically arranged on the top left and right. The locking heads are matched with the locking holes of the adjusting metal plate and the metal cover plate. By simultaneously inserting the locking heads into the locking holes of the pupil distance indicator base plate, the adjusting metal plate, and the metal cover plate in sequence, the locking heads are then rotated slightly with a wrench to connect the middle layer, the pupil distance indicator base plate, and the metal cover plate into a whole. At the same time, the clamping and fixing component is fixedly connected to the pupil distance adjustment mechanism.

[0014] Furthermore, the clamping and fixing component has two vertically elongated locking holes symmetrically arranged in the middle part for inserting clamping connectors. The clamping and fixing component has symmetrical fixing brackets on both sides, and the surface of the fixing brackets is covered with an ultra-thin silicone anti-slip sleeve, which has strong adhesion and improves clamping stability.

[0015] Furthermore, the clamping connector has a rectangular spring mounting locking hole in the middle for inserting the spring mounting, an annular drive component socket hole at the top for attaching the clamping drive component, and a connector locking head at the bottom for vertically inserting into the connector locking hole to lock and fix, thus connecting and fixing the clamping connector and the clamping fixing component into a whole.

[0016] Furthermore, the spring mounting component has two spring mounting locking heads symmetrically arranged at both ends for being inserted into the locking holes of the spring mounting component for locking and fixing. The top of the spring mounting component is also provided with a spring mounting hook for mounting and clamping the spring.

[0017] Furthermore, the clamping spring includes a spring sleeve hole formed by winding, with a drive connecting hook and a fixed abutment extending from both ends of the spring sleeve hole, respectively for hooking onto the clamping drive member and abutting onto the clamping fixing member.

[0018] Furthermore, the clamping drive component includes a clamping handle located at the top, and symmetrically arranged clamping beams on both sides of the clamping handle. A drive component clamping support is arranged perpendicularly to the bottom of each clamping beam. The surface of the drive component clamping support is also provided with an ultra-thin silicone anti-slip sleeve, which has strong adhesion and works in conjunction with the fixing component clamping support to improve clamping stability.

[0019] By means of the above-described solution, the present invention has at least the following advantages:

[0020] The entire fitting experience frame of this invention is made of 2.5mm steel, which is ultra-thin, ultra-hard, ultra-light, and rust-free. The one-piece cut clamp is tough and wear-resistant, and the ultra-thin silicone anti-slip sleeve has strong adhesion. The 6-position slots, combined with the movement of steel balls, provide better damping and more precise positioning, allowing for convenient and quick adjustment of pupillary distance. The overall structure is aesthetically pleasing, and the ultra-thin design ensures a better fit with the lenses, resulting in higher fitting accuracy and broad application prospects.

[0064] The working principle of this invention is as follows:

[0065] When assembling the progressive multifocal lens fitting experience frame of the present invention, firstly, the intermediate layer 11, the pupillary distance marking base plate 12, and the metal cover plate 13 are stacked completely according to their corresponding settings. Then, the fixing locking head 211 is simultaneously inserted into the locking hole on the surface of the pupillary distance marking base plate 12, the adjusting metal plate locking hole 1116, and the metal cover plate locking hole 133 in sequence. Then, the fixing locking head 211 is rotated by a wrench at a small angle to connect the intermediate layer 11, the pupillary distance marking base plate 12, and the metal cover plate 13. The clamping and fixing member 21 is then fixedly connected to the pupillary distance adjustment mechanism 1. Next, the spring mounting locking hole 231 in the middle part of the two clamping connectors 23 is inserted from the drive member clamping bracket 223 of the clamping drive member 22 and moved to the clamping crossbeam 222. Then, the connector locking head 233 of the clamping connector 23 is vertically inserted into the connector locking hole 212, and locked by rotating it slightly with a wrench, thus connecting the clamping connector 23 and the clamping and fixing member 21. Assemble the components into a single unit; then insert the spring mounting locking heads 242 at both ends of the spring mounting component 24 into the spring mounting locking holes 231 to lock and fix them. Finally, sleeve the clamping spring 25 onto the spring mounting hook 241, and hook the drive connecting hook 252 and the fixing abutment 253 onto the clamping drive component 22 and abut against the clamping fixing component 21 to complete the assembly. In use, directly clamp the fitting frame with the corresponding lens power onto the eyeglasses of the person being fitted, and then... Simply adjust the lever 112 to the appropriate pupillary distance setting to proceed with lens fitting. The entire fitting frame is made of 2.5mm steel, making it ultra-thin, ultra-hard, ultra-light, and rust-free. The one-piece cut clamp is tough and wear-resistant, and the ultra-thin silicone anti-slip sleeve provides strong adhesion. The 6-position groove, combined with the movement of the steel ball, provides better damping and more precise positioning, allowing for convenient and quick adjustment of pupillary distance. The overall structure is aesthetically pleasing, and the ultra-thin design ensures a better fit with the lenses, resulting in higher fitting accuracy and broad application prospects.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
