Description

Technical Field

[0001] This utility model relates to the field of vision lens technology, and more specifically, to a modular combination vision lens for controlling focal length. Background Technology

[0002] Vision lenses are optical lenses used to correct or assist vision. They are usually installed in eyeglasses, contact lenses, or other optical devices. By changing the refraction path of light, they help people with vision problems such as myopia, hyperopia, and astigmatism to see objects clearly. Their core function is to adjust the focusing position of light in the eyeball so that the image of an object falls accurately on the retina, thereby improving visual clarity.

[0003] When using existing vision lenses, the main body of the lens is generally composed of multiple fixed lenses, which makes it inconvenient to adjust the distance between the multiple lenses, thus making it difficult to control the focal length. This not only makes it difficult for users to quickly obtain a clear image in different visual scenarios (such as switching between near and far vision, dynamic visual needs), but also increases the risk of visual fatigue caused by the mismatch between the fixed focal length and actual visual needs. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular combination control lens for vision, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular combination control lens for visual acuity, comprising a lens and a mounting frame, wherein the lens is located inside the mounting frame, the mounting frame has a through groove, and an adjustment component is provided inside the through groove. The adjustment component includes a lead screw, a slide rod, two first bevel gears, a second bevel gear, and a rotating shaft. The front and rear ends of the lead screw are movably connected to the mounting frame via bearings, the front and rear ends of the slide rod are fixedly connected to the mounting frame, two sliding plates are movably sleeved on the lead screw and the slide rod respectively, and the opposite sides of the two sliding plates are fixedly connected to the lens. The first bevel gear is fixedly sleeved on the lead screw, and the top of the first bevel gear meshes with the second bevel gear, and the top of the second bevel gear is fixedly connected to the rotating shaft.

[0006] Furthermore, the rotating shaft is movably connected to the mounting frame via a bearing, and a handle is fixedly connected to the top of the rotating shaft.

[0007] It can be seen that the above technical solution is designed to facilitate the rotation of the shaft.

[0008] Furthermore, a friction ring is movably provided on the outer side of the handle, and the bottom end of the friction ring is fixedly connected to the mounting frame.

[0009] As can be seen, in the above technical solution, the friction between the rotating shaft and the mounting frame can be increased by using the handle and the friction ring together.

[0010] Furthermore, two limiting rings are fixedly sleeved on the slide rod, and both limiting rings are located on the front side of the second bevel gear.

[0011] As can be seen, in the above technical solution, the two limiting rings restrict the movement distance of the slide plate to prevent the slide plate from squeezing the second bevel gear.

[0012] Furthermore, the outer side of the mounting frame is fixedly fitted with two side plates, one of which has a connecting assembly on its rear side, the connecting assembly including a connecting plate, a locking bolt and multiple insert rods.

[0013] Furthermore, the connecting plate is fixed to one of the side plates by locking bolts, and one end of each of the plurality of insert rods is fixedly connected to the connecting plate.

[0014] Furthermore, buffer pads are fixedly fitted onto each of the plurality of the insertion rods, wherein the buffer pads serve to improve the stability between the insertion rods and the side plates.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model uses bolts to install one of the side plates onto the lens frame, thereby fixing the lens and the mounting frame to the lens frame. Turning the handle can drive the first bevel gear and the lead screw to rotate. The lead screw can drive the two slide plates and the lens to move horizontally. The position of the lens in the mounting frame can be adjusted as needed. The operation is simple and the focus can be easily controlled.

[0017] 2. This utility model places the connecting plate on the rear side of the mounting frame, with four of the insert rods inserted into the other side plate. Then, another lens is placed on the rear side of the connecting plate, and similarly, the other four insert rods are inserted into the side plate of the other lens. Finally, the two mounting frames and the connecting plate are fixed together by tightening bolts. Similarly, the mounting frames can be disassembled. The modular combination structure makes it easy to adjust the distance between multiple lenses. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Refer to the instruction manual appendix Figure 1-4 This embodiment of a modular combination control focal length vision lens includes a lens 1 and a mounting frame 2, with the lens 1 located inside the mounting frame 2. A through groove 5 is provided inside the mounting frame 2, and an adjustment component 6 is disposed inside the through groove 5. The adjustment component 6 includes a lead screw 601, a slide rod 602, two first bevel gears 604, a second bevel gear 605, and a rotating shaft 606. Both ends of the lead screw 601 are movably connected to the mounting frame 2 via bearings. Both ends of the slide rod 602 are fixedly connected to the mounting frame 2. Two sliding plates 603 are movably sleeved on the lead screw 601 and the slide rod 602, respectively, and the opposite sides of the two sliding plates 603 are fixedly connected to the lens 1. The first bevel gear 604 is fixedly sleeved on the lead screw 601, and the top of the first bevel gear 604 meshes with the second bevel gear 605. The top of the second bevel gear 605 is fixedly connected to the rotating shaft 606.

[0027] Furthermore, the rotating shaft 606 is movably connected to the mounting frame 2 via a bearing, and a handle 607 is fixedly connected to the top of the rotating shaft 606. A friction ring 608 is movably provided on the outside of the handle 607, and the bottom end of the friction ring 608 is fixedly connected to the mounting frame 2. Two limiting rings 609 are fixedly sleeved on the slide rod 602, and both limiting rings 609 are located in front of the second bevel gear 605.

[0028] Furthermore, two side plates 3 are fixedly fitted on the outer side of the mounting frame 2. A connecting component 4 is provided on the rear side of one of the side plates 3. The connecting component 4 includes a connecting plate 401, a locking bolt 402, and multiple insert rods 403. The connecting plate 401 is fixed to one of the side plates 3 by the locking bolt 402. One end of each of the multiple insert rods 403 is fixedly connected to the connecting plate 401. A buffer pad 404 is fixedly fitted on each of the multiple insert rods 403. The buffer pad 404 serves to improve the stability between the insert rod 403 and the side plate 3.

[0029] The connecting plate 401 is placed on the rear side of the mounting frame 2, and four of its insert rods 403 are inserted into another side plate 3, thereby improving the stability between the connecting plate 401 and the other side plate 3. At the same time, four buffer pads 404 are in contact with the side plate 3, which can further improve the stability between the connecting plate 401 and the other side plate 3. Then, another lens 1 is placed on the rear side of the connecting plate 401, and similarly, the other four insert rods 403 are inserted into the side plate 3 of the other lens 1. Finally, the two mounting frames 2 and the connecting plate 401 are fixed together by locking bolts 402. Similarly, the mounting frame 2 can be disassembled. The modular combination structure makes it easy to adjust the distance between multiple lenses 1.

[0030] The usage method of this embodiment is as follows:

[0031] In use, one of the side plates 3 is bolted to the frame, thus fixing the lens 1 and the mounting frame 2 to the frame. Rotating the handle 607 drives the rotating shaft 606 to rotate. The handle 607 and the friction ring 608 cooperate to increase the friction between the rotating shaft 606 and the mounting frame 2, thereby driving the second bevel gear 605 to rotate. Since the second bevel gear 605 meshes with the first bevel gear 604, the second bevel gear 605 can drive the first bevel gear 604 and the lead screw 601 to rotate. Since one of the sliding plates 603 is threaded to the lead screw 601, and the other sliding plate 603 cooperates with the sliding rod 602 to restrict the rotation of the lens 1, the lead screw 601 can drive the two sliding plates 603 and the lens 1 to move horizontally. The position of the lens 1 in the mounting frame 2 can be adjusted as needed. The operation is simple and the focus can be easily controlled. At the same time, the two limiting rings 609 limit the movement distance of the sliding plates 603 to prevent the sliding plates 603 from squeezing the second bevel gear 605.
