Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, and in particular to an eyeglass frame that prevents the lenses from falling off. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus, or amblyopia.

[0003] Eyeglass frames are an important component of eyeglasses, primarily serving to support the lenses. Aesthetically pleasing frames also contribute to visual appeal. They are made from materials such as metal, plastic, resin, and natural materials. In terms of style, they can be categorized into full-rim, semi-rim, and rimless types. The quality of the frames not only affects vision correction but also a person's appearance.

[0004] Currently, there are many materials and styles of eyeglass frames. The commonly used eyeglass frames are as follows: Plastic frames: The plastic used to make eyeglass frames is synthesized from organic natural materials, mainly thermosetting plastics and thermoplastic plastics.

[0005] Currently, thermoplastic plastics such as cellulose acetate and epoxy resin are commonly used; most lenses are encased within the frame.

[0006] For example, the prior art Chinese patent publication number "CN220064531U" provides an eyeglass frame to prevent the lens from falling off, including an eyeglass frame body, which is composed of an eyeglass lens and an eyeglass frame. One end of the eyeglass frame is equipped with a fixed temple, and the temple is connected to the eyeglass frame through a post. The eyeglass frame is provided with a fixing frame connected to the temple. The fixing frame is provided with a crossbeam, and a foldable hinge is welded to the crossbeam. The other end of the hinge is provided with a mounting frame, and the mounting frame has an eyeglass slot for mounting the eyeglass lens. Both sides of the lower end of the fixing frame are provided with a buckle slot. The bottom of the mounting frame is provided with an insert with a through hole corresponding to the buckle slot, and the mounting frame is fastened to the fixing frame by the bottom insert.

[0007] This device has the advantage of preventing eyeglass lenses from falling off, breaking, or being lost.

[0008] Existing eyeglass frames designed to prevent lenses from falling off have lenses placed inside the frame, but lack a stabilizing clamping structure on both sides. If the lens is subjected to vibration, impact, or pressure, it may fall off the frame, failing to securely hold the lens inside the frame. Utility Model Content

[0009] The purpose of this invention is to address the shortcomings of existing technologies where lenses are placed inside the frame and lack a stabilizing clamping structure on both sides, causing the lenses to fall off the frame when subjected to vibration, impact, or pressure. This invention provides an eyeglass frame that prevents lenses from falling off.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Design an eyeglass frame to prevent lenses from falling off, comprising a frame and temples connected to both ends. A lens is disposed in the center of the frame, and anti-fall-off mechanisms are disposed on both sides of the lens. A clamping mechanism is disposed in the middle of the upper and lower ends of the lens. The anti-fall-off mechanism includes a clamping strip and a limiting frame. The clamping strip is tightly fitted to the two side edges of the lens, and the limiting frame is tightly clamped to the outside of the clamping strip. The upper and lower ends of the limiting frame have positioning grooves, and the upper and lower ends of the frame have insertion holes. A positioning pin passes through the insertion hole, and the inner end of the positioning pin is inserted into the positioning groove. The clamping mechanism includes a clamping stud and a clamping washer, disposed in the middle of the upper and lower ends of the lens, for securing the lens tightly against the center of the frame. Protective strips are bonded to the upper and lower outer sides of the frame to prevent the positioning pin from falling off.

[0012] Furthermore, a connecting hole is provided in the middle of the upper and lower ends of the lens frame, the tightening stud is threaded through the connecting hole, the tightening washer is bonded to the inner end of the tightening stud and abuts against the middle of the upper and lower ends of the lens, and a cross groove is provided at the top of the tightening stud.

[0013] Furthermore, both the clamping strip and the limiting frame have the same shape as the lens, both being frame-shaped structures, and the clamping strip is made of silicone material.

[0014] Furthermore, the positioning groove and the insertion hole are aligned vertically, the depth of the positioning groove is less than the thickness of the limiting frame, and the top end of the positioning pin is recessed into the inner end of the insertion hole.

[0015] Furthermore, the protective strip is a long strip structure made of rubber and covers the outside of the insertion hole, which is located on both sides of the lens.

[0016] Furthermore, the connecting hole is a threaded hole structure and is vertically arranged. The tightening stud is threadedly connected to the connecting hole, and its top end is recessed inside the connecting hole. The protective strip covers the outside of the connecting hole.

[0017] Furthermore, the top clamping pad is made of rubber and has a circular structure.

[0018] The eyeglass frame proposed in this utility model to prevent eyeglass lenses from falling off has the following advantages:

[0019] 1. This utility model has a limiting frame set inside the frame and on both sides of the lens, and a clamping strip is bonded to the inside of the limiting frame. Therefore, after the lens is installed in the frame, the limiting frame drives the clamping strip to tightly clamp the edges of the lens on both sides. At the same time, the positioning pin passes through the insertion hole and is inserted into the positioning groove, so that the limiting frame is stably set inside the frame and the lens is tightly and stably clamped by the clamping strip to prevent the lens from falling off the frame.

[0020] 2. In this invention, a tightening stud and a tightening washer are provided at the middle of the upper and lower ends of the frame. Therefore, after the lens is installed in the frame and is clamped and stabilized by the clamping strip and the limiting frame, the tightening stud passes through the connecting hole and is tightened at the middle of the upper and lower ends of the lens by the tightening washer, keeping the lens firmly pressed inside the frame and improving the stability of the lens installation and use. At the same time, the protective strips bonded to the upper and lower sides of the frame can not only cover the positioning pin and the tightening stud, but also reduce the impact of the frame.

[0030] The tightening mechanism includes a tightening stud 7 and a tightening pad 13, which are located at the middle of the upper and lower ends of the lens 4, and are used to fasten the lens 4 to the middle of the frame 1.

[0031] The upper and lower outer sides of the frame 1 are bonded with protective strips 3 to prevent the positioning pins 6 from falling off.

[0032] A limiting frame 5 is provided inside the frame 1 and on both sides of the lens 4. A clamping strip 10 is bonded to the inside of the limiting frame 5. Therefore, after the lens 4 is installed in the frame 1, the limiting frame 5 drives the clamping strip 10 to tightly clamp the edges of the lens 4 on both sides. At the same time, the positioning pin 6 passes through the insertion hole 8 and is inserted into the positioning groove 11, so that the limiting frame 5 is stably set inside the frame 1 and the clamping strip 10 tightly and stably clamps the lens 4 to prevent the lens 4 from falling off the frame.

[0033] The positioning groove 11 and the insertion hole 8 are aligned vertically. The depth of the positioning groove 11 is less than the thickness of the limiting frame 5. The top end of the positioning pin 6 is recessed into the inner end of the insertion hole 8. Example

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The diagram illustrates an eyeglass frame designed to prevent lenses from falling off. It includes a frame 1 and temples 2 connected to both ends. A lens 4 is positioned in the center of the frame 1, with anti-fall-off mechanisms on both sides of the lens 4. A clamping mechanism is located at the center of the upper and lower ends of the lens 4. The anti-fall-off mechanism includes a clamping strip 10 and a limiting frame 5. The clamping strip 10 fits tightly against the two edges of the lens 4, and the limiting frame 5 clamps tightly against the outer side of the clamping strip 10. Positioning grooves 11 are formed at the upper and lower ends of the limiting frame 5. Insertion holes 8 are formed at the upper and lower ends of the frame 1, located on both sides of the lens 4. Positioning pins 6 pass through the interior of the insertion holes 8, with their inner ends inserted into the positioning grooves 11. The clamping mechanism includes a clamping stud 7 and a clamping pad 13, positioned at the center of the upper and lower ends of the lens 4 to securely clamp the lens 4 to the center of the frame 1. Protective strips 3 are bonded to the upper and lower outer sides of the frame 1 to prevent the positioning pins 6 from falling off. The protective strip 3 is a long strip structure made of rubber and covers the outside of the insertion hole 8.

[0035] A limiting frame 5 is provided inside the frame 1 and on both sides of the lens 4. A clamping strip 10 is bonded to the inside of the limiting frame 5. Therefore, after the lens 4 is installed in the frame 1, the limiting frame 5 drives the clamping strip 10 to tightly clamp the edges of the lens 4 on both sides. At the same time, the positioning pin 6 passes through the insertion hole 8 and is inserted into the positioning groove 11, so that the limiting frame 5 is stably set inside the frame 1 and the clamping strip 10 tightly and stably clamps the lens 4 to prevent the lens 4 from falling off the frame.

[0036] The frame 1 has a connecting hole 9 in the middle of its upper and lower ends. The tightening stud 7 is threaded through the connecting hole 9. The tightening pad 13 is bonded to the inner end of the tightening stud 7 and abuts against the middle of the upper and lower ends of the lens 4.

[0039] Working method: Limiting frames 5 are set inside the frame 1 and on both sides of the lens 4. Clamping strips 10 are bonded to the inside of the limiting frames 5. Therefore, after the lens 4 is installed in the frame 1, the limiting frames 5 drive the clamping strips 10 to tightly clamp the edges of the lens 4 on both sides. At the same time, the positioning pins 6 pass through the insertion holes 8 and are inserted into the positioning grooves 11, so that the limiting frames 5 are stably set inside the frame 1 and the lens 4 is tightly and stably clamped by the clamping strips 10 to prevent the lens 4 from falling off the frame.

[0040] A tightening stud 7 and a tightening pad 13 are provided in the middle of the upper and lower ends of the frame 1. Therefore, after the lens 4 is installed in the frame 1 and is clamped and stabilized by the clamping strip 10 and the limiting frame 5, the tightening stud 7 is rotated through the cross groove 12. The tightening stud 7 passes through the connecting hole 9 and is tightened in the middle of the upper and lower ends of the lens 4 by the tightening pad 13, keeping the lens 4 firmly pressed inside the frame 1 and improving the stability of the lens 4 during installation and use. At the same time, the protective strips 3 bonded to the upper and lower sides of the frame 1 can not only cover the positioning pin 6 and the tightening stud 7, but also reduce the impact of the frame 1.
