Description

Technical Field

[0001] The present application relates to the field of lens technology, and in particular to a concave-convex combined lens. Background Art

[0002] Meniscus lenses combine the characteristics of concave and convex lenses, which means that one side of the lens is convex and the other side is concave. The behavior of this lens depends on the radius of curvature of the concave and convex sides, the refractive index of the lens material, and the relative shape difference of the concave and convex sides, and combined meniscus lenses are very useful in many optical applications. By combining concave and convex lenses, it is possible to design a lens system that has the ability to both converge and diverge light.

[0003] There are many combinations of concave and convex lenses: directly attaching a concave lens and a convex lens together. Using an adjustment structure to make a certain distance between two transparent objects to provide better optical performance, etc., are all a type of combined concave and convex lenses. At present, when using an adjustment structure to adjust the distance of concave and convex lenses, a threaded rod is generally used to drive the installation frame to move, so as to move and adjust the lens on the installation frame. Although it is convenient to use, after adjustment, it is easy to accidentally touch the threaded rod and cause it to rotate, so that the installation frame drives the lens to continue to move, thereby affecting the control of the distance between the two lenses. Therefore, a concave and convex combination lens is designed to solve the above-mentioned problems. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a concave-convex combined lens. Figure 1-3 A concave-convex combined lens comprises a fixing platform 1, both sides of which are fixedly connected to an adjusting frame 2, and a through groove is provided on the upper part of the adjusting frame 2, such as Figure 2As shown, the mounting plate 5 is slidably connected in the through groove, the upper end of the mounting plate 5 is fixedly connected to the fixing plate 3, the upper end of the fixing plate 3 is fixedly connected to the mounting frame 4, the mounting frame 4 is used to fix the lens, the front part of the lower end of the mounting plate 5 is fixedly connected to the gear plate 6, the upper end of the gear plate 6 is provided with a gear 7, and the front part of the gear 7 is rotatably connected to the adjusting frame 2; in the initial state, the gear plate 6 is in contact with the bottom wall of the adjusting frame 2, when it is necessary to adjust the lens on the mounting frame 4, the mounting plate 5 can be pulled up, and the gear plate 6 can be driven to rise, so that the gear plate 6 is meshed with the gear 7, and then the gear 7 is rotated, the gear 7 drives the gear plate 6 to move, and drives the mounting plate 5 to move, so as to achieve the effect of driving the lens in the upper mounting frame 4 to move and adjust;

[0021] By adopting the above technical solution, in order to facilitate the rotation of the gear 7, the middle part of the front side of the gear 7 is fixedly connected to the rotating rod 12, and the front part of the rotating rod 12 is fixedly connected to the turning handle.

[0022] By adopting the above technical solution, when there is no need to use the gear 7 to drive the gear plate 6 to move and drive the lens in the mounting frame 4 to adjust, in order to prevent the gear plate 6 and the mounting plate 5 from moving, a baffle 8 is fixedly connected to the front middle part of the mounting plate 5, and a plug plate is fixedly connected to the lower end of the baffle 8. In the initial state, the gear plate 6 contacts the inner wall of the adjustment frame 2, and the plug plate at the lower end of the baffle 8 contacts the gear 7. The plug plate is inserted into the tooth gap of the gear 7, which hinders the movement of the baffle 8, and the plug plate hinders the rotation of the gear 7, so that the mounting plate 5 and the mounting frame 4 cannot drive the lens to move.

[0023] By adopting the above technical solution, a spring 9 is fixedly connected to the upper end of the baffle 8, and a slide plate 10 is fixedly connected to the upper end of the spring 9. The upper end of the slide plate 10 is slidably connected to the inner wall of the adjustment frame 2. The baffle 8 is pushed down by the spring 9, so that the plug plate at the lower end of the baffle 8 contacts the gear 7 and hinders the rotation of the gear 7 and the movement of the baffle 8, thereby avoiding the change of the lens position on the mounting frame 4.

[0024] By adopting the above technical solution, a telescopic sleeve 11 is fixedly connected to the middle of the upper end of the baffle 8, and the upper end of the telescopic sleeve 11 is fixedly connected to the slide plate 10. The telescopic sleeve 11 is used to protect the spring 9 to prevent the baffle 8 from causing the mounting plate 5 to shake after the spring 9 tilts.

[0025] By adopting the above technical solution, further, a magnetic plate 13 is fixedly connected to the bottom of the adjustment frame 2, and the magnetic plate 13 and the gear plate 6 are magnetically connected. In the initial state, the gear plate 6 is magnetically attracted by the magnetic plate 13, which can avoid the movement of the lens caused by directly pushing the installation plate 5 to move.

[0026] The implementation principle of a concave-convex combination lens in an embodiment of the present application is: when the position of the lens needs to be adjusted, the fixing plate 3 is pulled upward, so that the fixing plate 3 drives the mounting frame 4 to move and drives the mounting plate 5 at the lower end to move, so that the mounting plate 5 drives the gear plate 6 to rise, drives the baffle 8 to rise, and squeezes the spring 9 to contract, the plug plate of the baffle 8 is separated from the gear 7, and the gear plate 6 engages with the gear 7 after contact, and then the handle is turned to drive the handle to rotate the rotating rod 12 and drive the gear 7 to rotate, the gear 7 drives the gear plate 6 to move, and drives the mounting plate 5 on one side to move, the mounting plate 5 drives the mounting frame 4 to move, thereby driving the lens to move, and adjusting the position of the lens.

[0027] After adjustment, the fixing plate 3 can be loosened to allow the spring 9 to recover and push the baffle plate 8 down. The baffle plate 8 drives the plug plate to be inserted into the gear 7 again to prevent the gear 7 from rotating. After the lower end gear plate 6 is lowered, it is connected to the magnetic plate 13 again to prevent the gear plate 6 from moving, thereby fixing the position of the mounting frame 4 at the upper end of the mounting plate 5.
