Description

Technical Field

[0001] This utility model relates to the technical field of optical eyeglass frames, specifically an anti-loosening outward-folding optical eyeglass frame. Background Technology

[0002] Eyeglass frames are an important component of eyeglasses, primarily serving to support the lenses. Aesthetically pleasing frames also contribute to the overall look. 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. Optical eyeglass frames are a type of eyeglass frame.

[0003] Existing eyeglass frames have drawbacks, such as being unsuitable for elderly users and being prone to damage at the joints. To address these issues, a replaceable frame optical eyeglass frame is disclosed in existing technology (Chinese patent application number CN201220444234.1, application date 2012-09-03). This frame, with its widened plate structure, facilitates increasing the frame width and prevents damage to the joints due to prolonged pressure. Furthermore, the frame's temple structure makes it suitable for elderly users and allows for easier identification of the glasses' position.

[0004] Although the above-mentioned devices can solve the existing problems, there are still some shortcomings in their use. Some elderly people with presbyopia need to use reading glasses to help them read, but they need to take off and put on the reading glasses intermittently in the later stages, which is quite cumbersome.

[0005] Therefore, we proposed that an anti-loosening outward-folding optical eyeglass frame can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anti-loosening outward-folding optical eyeglass frame to solve the problem mentioned in the background art that some elderly people with presbyopia need to use reading glasses when reading, but the operation is cumbersome because they need to take them off and put them on intermittently.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening outward-folding optical eyeglass frame, comprising an eyeglass frame body, wherein both ends of the eyeglass frame body are fixed with posts, and temple bodies are embedded and fixed at the rotating parts of the posts; a nose pad is also provided in the middle of the eyeglass frame body, the top of the nose pad is connected to the middle of the eyeglass frame body by a fixing bolt, and one side of the eyeglass frame body is rotatably connected to the eyeglass frame body by an anti-loosening mechanism.

[0008] As a preferred technical solution of this application, the anti-loosening mechanism includes toothed blocks fixed on both sides, and the inner center of the toothed blocks is rotatably disposed on the left and right sides of the eyeglass frame body.

[0009] As a preferred technical solution of this application, a spring is provided on the inner side of the tooth block, the spring is made of high elastic steel sheet, and the rotation angle of the eyeglass frame body is 0-140 degrees.

[0010] As a preferred technical solution of this application, the toothed block is multi-toothed, and the outer side of the toothed block is fixed to the outer side of the eyeglass frame body.

[0011] As a preferred technical solution of this application, the nose pad includes positioning holes opened on both sides of the top, and two sets of nose pad bodies are fixed at the lower end of the nose pad, and a hinge is provided at the top center of the nose pad.

[0012] As a preferred technical solution of this application, the positioning hole is fixedly connected to the eyeglass frame body through a fixing bolt, and the inner side of the hinge is rotatably positioned at the middle of the eyeglass frame body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-loosening outward-facing optical eyeglass frame is equipped with an anti-loosening mechanism. The anti-loosening mechanism enables the inner spring plate of the toothed block to rotate while the toothed block rotates. When the rotation reaches a suitable angle, it can prevent the eyeglass frame body from loosening due to its own weight. The specific details are as follows:

[0014] The toothed block allows the frame to rotate, with one end capable of doing so. The frame rotates within 0-140 degrees via a spring inside the toothed block, and resets itself using the spring's elasticity. The spring's force also limits the toothed block's position, locking the frame and preventing accidental reset without external force. Furthermore, a hinge is included. The nose pad's positioning hole at one end is fixed to the frame via a bolt, and the hinge allows for stable rotation between the nose pad and frame. Attached Figure Description

[0022] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: an anti-loosening outward-folding optical eyeglass frame.

[0024] Example 1: To address the issue that some elderly people with presbyopia need to use reading glasses while reading, but the process of intermittently removing and putting on the glasses is cumbersome, please refer to the attached... Figure 1 -Appendix Figure 3 Appendix Figure 5 and attached Figure 6 The device includes an eyeglass frame body 1, with posts fixed at both ends and temple bodies 2 embedded at the rotating parts of the posts; a nose pad 3 is also provided in the middle of the eyeglass frame body 1, with the top of the nose pad 3 connected to the middle of the eyeglass frame body 1 by a fixing bolt 4; one side of the eyeglass frame body 1 is rotatably connected to the eyeglass frame body 5 by an anti-loosening mechanism; the anti-loosening mechanism includes toothed blocks 6 fixed at both sides, with the inner center of the toothed blocks 6 rotatably positioned on the left and right sides of the eyeglass frame body 1; a spring piece 7 is provided on the inner side of the toothed blocks 6, the spring piece 7 being a high-elastic steel sheet; the rotation angle of the eyeglass frame body 5 is 0-140 degrees; the toothed blocks 6 are multi-toothed, and the outer side of the toothed blocks 6 is fixed to the outer side of the eyeglass frame body 5.

[0025] After the elderly wear the eyeglasses frame, the lenses inside the frame body 5 are flipped. At this time, the elderly can hold the surface of the frame body 1 with one hand and the side of the frame body 5 with the other hand. By rotating the frame body 5, the frame body 5 can be rotated on the surface of the frame body 1 via the toothed block 6. The frame body 5 can be flipped outward by 140 degrees, and the toothed block 6 will also rotate. In addition, after the toothed block 6 rotates, the spring 7 set on the inner side of the toothed block 6 will also lock, so that when the frame body 5 is released, it will not become loose. This makes it easy to flip the frame body 5 outward, thus solving the problem of the cumbersome operation of intermittently taking off and putting on reading glasses in the later stages.

[0026] Example 2: This example differs from Example 1 in that it adds a stable mechanism for rotating the eyeglass frame body 5, preventing loosening during rotation. See attached diagram. Figure 3 and attached Figure 4 The nose pad 3 includes positioning holes 31 on both sides of the top, and two sets of nose pad bodies 32 are fixed at the lower end of the nose pad 3. A hinge 33 is also provided at the top center of the nose pad 3. The positioning holes 31 are fixedly connected to the eyeglass frame body 1 by fixing bolts 4, and the inner side of the hinge 33 is rotatably set at the center of the eyeglass frame body 5.

[0027] To further facilitate the rotation of the eyeglass frame body 5, the hinge 33 on the top of the nose pad 3 is rotatably mounted on one side of the eyeglass frame body 5, and the positioning hole 31 on the top of the nose pad 3 is fixed to the top surface of the eyeglass frame body 1 by a fixing bolt 4. When the eyeglass frame body 5 rotates, it can rotate stably through the hinge 33, thus making the eyeglass frame body 5 more stable during rotation.
