Description

Technical Field

[0001] This utility model belongs to the field of lens mounting technology, and more specifically, it relates to an optical lens mounting mechanism. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. Qualified glass blocks are then heated and forged to form optical lens blanks.

[0003] Based on the above, the inventors have discovered the following problems: When optical lenses are installed with frames, the lenses are generally cut to fit the size of the frames and then pressed into the inside of the frames. This method of fixing is not good enough, so screws are used for fixing. The screws are inserted from the side of the frames and then into the side of the lenses. However, this method can easily cause the screws to damage the lenses, which is not conducive to the long-term use of the lenses.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an optical lens mounting mechanism in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an optical lens mounting mechanism that solves the problem that screws, which are inserted from the side of the frame, can easily damage the lens.

[0006] The purpose and effect of this utility model's optical lens mounting mechanism are achieved by the following specific technical means:

[0007] An optical lens mounting mechanism includes temples, lenses, and frames. The frames include a first frame and a second frame. A first separator ring is provided on the inner side of the first frame, and a second separator ring is provided on the inner side of the second frame. The first separator ring and the second separator ring correspond to each other, and when the first separator ring and the second separator ring are fitted together, a circular groove is formed on the inner side of the first frame and the second frame to accommodate the edge of the lens. The thickness of the circular groove is adapted to the thickness of the lens.

[0008] Furthermore, the first frame has a first connecting hole, and the second frame has a second connecting hole. Screws are installed inside the first and second connecting holes, and the first and second frames are connected by screws.

[0009] Further, the first and second separation rings are provided with protective pads, and the two protective pads can be attached to each other.

[0010] Further, the inner side of the second frame is provided with an auxiliary pad, and the auxiliary pad is attached to the edge of the lens.

[0011] Further, the second separation ring is provided with a positioning column, and the first separation ring is provided with a positioning hole, and the positioning column is located in the positioning hole.

[0012] Further, the positioning hole and the positioning column are in plurality and are uniformly distributed in a circle, the diameter of the positioning column is matched with the diameter of the positioning hole, and the length of the positioning column is the same as the depth of the positioning hole.

[0013] Compared with the prior art, the optical lens mounting mechanism has the following beneficial effects:

[0014] In the optical lens mounting mechanism, the second frame is pushed to make the positioning column enter the inside of the positioning hole, so that the second frame can be limited to prevent the second frame from rotating, and then the first frame and the second frame are fixed by the screw, so that the distance between the second frame and the first frame is reduced, and the lens is fixed by the second frame and the first frame.
