Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an adjustable eyeglass frame. Background Technology

[0002] Eyeglasses have a wide range of uses, including sun protection and prescription glasses. However, the width of commonly used eyeglass frames is not easily adjustable, making it difficult for wearers with wider facial features to find suitable glasses. Eyeglass frames that cannot be adjusted in width can easily chafe the skin of the face, causing extreme discomfort when wearing them.

[0003] Chinese patent publication number "CN221595446U2" discloses "an adjustable eyeglass frame," which includes a frame with a side frame rotatably connected to it. The side frame contains an elastic component, which includes an ear hook, a sliding post, and a serrated groove. The serrated groove is formed within the side frame, and the ear hook and sliding post are engaged and slidably connected to the side frame. The ear hook is engaged via the serrated groove. Since an internal adjustment component is provided at the top and bottom of each side frame, the abutment blocks on both sides simultaneously lock and limit the adjustment block. This method utilizes the principle of triangular clamping to fix the eyeglass frame, effectively preventing ear pain caused by spring retraction and improving the user experience. The serrated structure of the serrated groove locks the position of the sliding post. Rotating the ear hook causes the ratchet at the connecting end to rotate unidirectionally around the sliding post. When the appropriate angle is reached, the internal abutment block rebounds due to the spring, locking the ratchet and achieving a limiting and locking effect, thus improving adaptability to different users.

[0004] This patent only adjusts the angle of the ear hooks to fit a wider range of people. However, the adjustment angle of the ear hooks is limited. Different people have different body shapes and facial contours, so adjusting only the ear hooks is not suitable. The adjustment range is limited and the applicable range is low. Therefore, we have proposed an adjustable eyeglass frame. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable eyeglass frame to solve the problems mentioned in the background art, such as the limited adjustment angle of the ear hooks, the large differences in the size of different people's faces and body shapes, the limited adjustment range, and the low applicability of the ear hook adjustment alone.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable eyeglass frame, comprising a frame, a temple, an extension rod, and ear hooks. The temple is rotatably connected to both sides of the frame. The extension rod is inserted into the end of the temple. The ear hooks are fixedly connected to the end of the extension rod. The temple has a telescopic hole inside, and an adjusting screw is rotatably connected inside the telescopic hole. A limiting groove is formed at the bottom of the inner cavity of the telescopic hole. A telescopic rod is fixedly connected to the front end of the extension rod and inserted into the telescopic hole. A stud is fixedly connected to the end of the telescopic rod and screwed onto the outside of the adjusting screw. A damping sleeve is fixedly connected to the outer wall of the stud, and the outer wall of the damping sleeve is tightly fitted to the inner wall of the telescopic hole. A limiting block is fixedly connected to the top of the telescopic rod and slidably connected to the inner cavity of the limiting groove.

[0007] Preferably, a cover plate is rotatably connected to the upper side of the outer wall of the ear hook, an operating cavity is opened on the upper side of the inner side of the ear hook, and an installation groove is opened in the middle of the inner side of the ear hook.

[0008] Preferably, the end of the adjusting screw passes through the telescopic rod and the extension rod and extends into the interior of the operating cavity, and a rotating knob is fixedly connected to the end of the adjusting screw.

[0009] Preferably, the mounting groove is provided with an adjustment knob, and a rotating screw is fixedly connected to the end of the adjustment knob. The rotating screw is screwed into the inner cavity of the mounting groove.

[0010] Preferably, a hidden groove is formed on one side of the ear hook, an adapter groove is formed in the inner wall of the hidden groove, a push plate is embedded in the inner cavity of the adapter groove, and the end of the rotating screw passes through and extends into the inner cavity of the adapter groove and is rotatably connected to the push plate.

[0011] Preferably, an adjustment plate is rotatably connected to the inner cavity of the hidden groove. The adjustment plate is an arc-shaped plate. A protective sleeve is fixedly connected to one side of the ear hook and outside the adjustment plate. The protective sleeve is made of silicone material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This adjustable eyeglass frame allows for adjustment by opening the cover and rotating the knob to turn the adjusting screw. The screw, connected to the stud, causes the telescopic rod to move within the telescopic hole, while the limiting block moves within the limiting groove. This adjusts the distance between the telescopic rod, the extension rod, and the lens stem. A damping sleeve moves within the telescopic hole along with the stud, ensuring the stud remains stably within the telescopic hole after adjustment. This allows for a wide range of adjustments to the length of the eyeglass frame, making it suitable for a broader range of applications.

[0014] 2. This adjustable eyeglass frame, by rotating the adjustment knob in the mounting slot, drives the rotating screw to rotate, which in turn moves the push plate in the adapter slot. The push plate contacts the adjustment plate and pushes the adjustment plate to rotate and adjust. While the adjustment plate rotates and adjusts in the hidden slot, it also squeezes the protective cover, causing the protective cover to deform and fit more snugly to the user's ears, thereby improving the stability of wearing the eyeglass frame and making it suitable for a wider range of people.

The damping sleeve 330 moves within the telescopic hole 210 with the movement of the stud 320, and after adjustment, the stud 320 can be stably stopped inside the telescopic hole 210.

[0029] In summary, the length of the eyeglass frames can be adjusted, and the adjustment range is large, making them more suitable for a wider range of applications.

[0030] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6An ear hook 400 has a cover plate 410 rotatably connected to the upper side of its outer wall. An operating cavity 420 is formed on the upper side of the ear hook 400's interior. A mounting groove 430 is formed in the middle of the ear hook 400's interior. An adjustment knob 431 is provided inside the mounting groove 430, and a rotating screw 432 is fixedly connected to the end of the adjustment knob 431. The rotating screw 432 is screwed into the inner cavity of the mounting groove 430. A hidden groove 440 is formed on one side of the ear hook 400. An adapter groove 441 is formed in the inner wall of the hidden groove 440. A push plate 442 is embedded in the inner cavity of the adapter groove 441. The end of the rotating screw 432 passes through and extends into the inner cavity of the adapter groove 441, and is rotatably connected to the push plate 442. An adjustment plate 450 is rotatably connected to the inner cavity of the hidden groove 440. The adjustment plate 450 is an arc-shaped plate. A protective sleeve 460 is fixedly connected to one side of the ear hook 400 and outside the adjustment plate 450. The protective sleeve 460 is made of silicone.

Under the action of the adjusting screw 220 and the stud 320, the telescopic rod 310 moves within the telescopic hole 210. The limiting block 340 moves within the limiting groove 230, thus adjusting the distance between the telescopic rod 310, the extension rod 300, and the lens rod 200. Furthermore, the damping sleeve 330 moves within the telescopic hole 210 along with the stud 320. After adjustment, the stud 320 can be stably placed inside the telescopic hole 210. Rotate the adjustment knob 431 in the mounting groove 430. The adjustment knob 431 drives the rotating screw 432 to rotate. The rotating screw 432 drives the push plate 442 in the adapter groove 441 to move. The push plate 442 contacts the adjustment plate 450 and pushes the adjustment plate 450 to rotate and adjust. While the adjustment plate 450 is rotating and adjusting in the hidden groove 440, it also squeezes the protective sleeve 460, causing the protective sleeve 460 to deform and fit more closely to the user's ear.
