Description

Technical Field

[0001] This utility model relates to the technical field of eyeglass frames, specifically an eyeglass frame with an adjustable nose pad structure. Background Technology

[0002] As precision products used to correct vision and enhance facial aesthetics, the comfort and stability of eyeglass frames are of paramount importance. The nose pads, as the supporting components that come into direct contact with the bridge of the nose, have always been a key design focus in terms of structure and adjustability. Optometrists adjust the angle of the nose pad stems to accommodate the different heights and curvatures of the nose bridges of different users, aiming to achieve a more personalized wearing experience. These existing designs provide an important technological foundation for the comfortable wearing of eyeglasses.

[0003] Chinese Patent No. CN202322195339.9 discloses a digital luminous eyeglass frame, including an eyeglass frame body with a connecting frame between the two frames. An adjustable component is located in the middle of the eyeglass frame body, comprising a telescopic structure and a fastening structure. The telescopic and fastening structures work together to adjust the width between the frames. This invention includes a first adjusting frame, a second adjusting frame, and screws. The first and second adjusting frames move within adjusting grooves via adjusting rods, allowing users to adjust the distance between the two frames to suit different face shapes and usage habits. A luminous strip is fixed in a fixed groove, absorbing external light and emitting light in the dark to help users locate their glasses. While this design allows for adjusting the distance between the frames and includes a luminous strip for finding the glasses, it lacks an adjustable nose pad component, resulting in poor user comfort and limited flexibility in adjusting the fit, leading to unsatisfactory performance.

A nose pad 7 is provided at the rear side of each eyeglass frame 2 near the inner side, and an adjustment component 8 is installed at the rear side of each eyeglass frame 2 near the inner side.

[0019] The adjustment assembly 8 includes an L-shaped connecting plate 81 fixedly installed on the back side of the right eyeglass frame 2 near the inner side and a sliding frame 82 slidably installed on the outer side of the L-shaped connecting plate 81. A T-bolt 83 is threaded through the top of the sliding frame 82, and a connecting block 84 is fixedly installed in the middle of the back side of the sliding frame 82. The rear side of the connecting block 84 is fixedly installed on the adjacent nose pad 7, which can realize the adjustment of the position of the nose pad 7 and improve the comfort of the wearer.

[0020] The top of the L-shaped connecting plate 81 is provided with several equally spaced snap-fit ​​slots 811, and the output end of the T-shaped bolt 83 is inserted into the inner cavity of one of the snap-fit ​​slots 811, which facilitates the adjustment work.

[0021] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 1-2 and Figure 4-7The snap-fit ​​assembly 5 includes a mounting block 51 slidably mounted on the rear side of the inner cavity of the left mounting groove 4 and insert plates 52 fixedly mounted on the front side of the mounting block 51 near the left and right sides. A fixing frame 53 is provided on the front side of the mounting block 51, and a support plate is fixedly mounted on the front side of the fixing frame 53 near the bottom. The front side of the support plate is fixedly mounted on the inner wall of the inner cavity of the mounting groove 4. Insertions are provided on the fixing frame 53 near the left and right sides. The front sides of the insert plates 52 pass through adjacent inserts and extend to the outside of the fixing frame 53. The top of the fixing frame 53 is flush with the outside of the fixing frame 53. Rotating rods 54 are movably installed at the middle of the bottom. The outer ends of the rotating rods 54 extend movably through to the outside of the mounting groove 4. Rotating plates 55 are fixedly sleeved on the outer side of the rotating rods 54 near the inner end. Hinges 56 are movably installed on the rotating plates 55 near the front and rear sides. An L-shaped plate 57 is movably installed on the end of the hinge plate 56 away from the adjacent rotating plate 55. Movable plates 58 are provided at the middle of the left and right sides of the fixed frame 53. The side of the L-shaped plate 57 away from the adjacent hinge plate 56 is fixedly installed on the adjacent movable plate 58.

[0022] A knob 541 is fixedly installed on the outer end of the rotating rod 54 to facilitate the rotation of the rotating rod 54.

[0023] Each movable plate 58 has a snap-fit ​​ball 59 in the middle of its opposite side, and an opening is provided on the opposite side of the inner cavity of the insertion port. The outer side of the snap-fit ​​ball 59 is located in the inner cavity of the adjacent opening.

[0024] The opposite side of the insert plate 52 is provided with a circular slot 521 near the middle, and the opposite side of the snap ball 59 is inserted into the inner cavity of the adjacent circular slot 521, which facilitates the snap-fit ​​operation.

[0025] Guide rods 581 are slidably installed on the movable plate 58 near the top and bottom. The inner ends of the guide rods 581 are fixedly installed on the fixed frame 53. The outer sides of the guide rods 581 are fitted with return springs 582. The two ends of the return springs 582 are fixedly installed on the fixed frame 53 and the adjacent movable plate 58, respectively, which facilitates the movement and restoration of the movable plate 58.

[0026] A fixing rod 591 is fixedly installed in the middle of the opposite side of the locking ball 59, and the opposite end of the fixing rod 591 is fixedly installed on the adjacent movable plate 58, which can drive the locking ball 59 to move left and right synchronously with the movable plate 58.

[0027] Working principle: During use, the staff can wear the eyeglass frame 2 and lenses 3 on their face through the temples 6. After wearing, the nose pads 7 will contact the wearer's nose bridge, and the position of the nose pads 7 can be adjusted. By rotating the T-bolt 83, it can be moved away from the inner cavity of a locking groove 811. By sliding the sliding frame 82 on the outside of the L-shaped connecting plate 81, the position of the nose pads 7 can be adjusted through the connecting block 84. After adjusting to a comfortable position, the T-bolt 83 can be rotated in the opposite direction to allow it to re-insert into the inner cavity of the locking groove 811. In addition, when the temples 6 are damaged, they can be disassembled and replaced. By rotating the two knobs 541 on the adjacent side, the adjacent rotating rod 54 will rotate. When the rotating rod 54 rotates, it will drive the adjacent rotating plate 55 to rotate. When the rotating plate 55 rotates, it will pass through... The hinge plate 56 drives the adjacent L-shaped plate 57 to move outward, which in turn drives the movable plates 58 on both sides to move in the opposite direction and presses the adjacent return spring 582. This, in turn, drives the adjacent snap-fit ​​ball 59 to move in the opposite direction through the fixed rod 591, and slowly moves it away from the inner cavity of the adjacent circular snap-fit ​​groove 521, thus releasing the snap-fit ​​on the insert plate 52. Then, moving the mounting block 51 backward will drive the insert plate 52 to move backward, thus moving it away from the fixed frame 53. During installation, it is only necessary to drive the mounting block 51 and the insert plate 52 into the inner cavity of the mounting groove 4. The snap-fit ​​ball 59 is then pressed by the insert plate 52, causing it to move outward under the action of the return spring 582. When it moves to the appropriate position, the snap-fit ​​ball 59 is inserted into the inner cavity of the adjacent circular snap-fit ​​groove 521 under the action of the return spring 582, thus achieving snap-fit ​​fixation.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
