Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to a lens holding mechanism. Background Technology

[0002] A lens is an optical element made of transparent material that contains at least one curved surface. Its main function is to refract (redirect) transmitted light, converging light to a focal point or diverging it. Lenses have a wide range of applications, including eyeglasses, cameras, automotive headlights, laser systems, virtual reality glasses, and fiber optic networks.

[0003] When using traditional lenses, they need to be kept fixed during testing. The fixing methods include clip fixing or fixing with positioning pins. After being fixed by clips and positioning pins, the fixed lens needs to be caught by hand when it is released to prevent it from falling and being damaged. At the same time, the traditional clip and positioning pin fixing methods cannot meet the installation requirements of lenses of different thicknesses. Therefore, a lens holding mechanism is needed. Utility Model Content

[0004] The purpose of this invention is to provide a lens holding mechanism to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lens holding mechanism includes a fixed plate, a first guide rail fixedly connected to the upper surface of the fixed plate, a pair of adjusting plates slidably connected to the upper surface of the first guide rail, a lifting plate fixedly connected to the upper surface of the adjusting plate, a circular clamping plate fixedly connected to the surface of the lifting plate, a lens body disposed between the pair of circular clamping plates, and a clamping and positioning mechanism disposed on the surface of the fixed plate.

[0007] Preferably, the clamping and positioning mechanism includes an L-shaped plate fixedly connected to the surface of the fixed plate, the inner wall of the L-shaped plate being threadedly connected to a threaded rod, and one end of the threaded rod being rotatably connected to a movable plate.

[0008] Furthermore, a second guide rail is fixedly connected to the surface of the L-shaped plate, the lower surface of the movable plate is slidably connected to the surface of the second guide rail, and a first convex shaft is fixedly connected to the upper surface of the adjusting plate.

[0009] Preferably, a second convex shaft is fixedly connected to the upper surface of the movable plate, and the surfaces of the first convex shaft and the second convex shaft are rotatably connected to the same connecting rod.

[0010] Furthermore, an arc-shaped plate is fixedly connected to the upper surface of the fixing plate, and a storage groove is formed on the upper surface of the arc-shaped plate, the storage groove corresponding to the position of the lens body.

[0011] Preferably, the inner wall of the circular clamp is provided with a groove, the inner wall of the groove is pressed against the surface of the lens body, and a handwheel is fixedly connected to the end of the threaded rod away from the movable plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] The screw rod rotates to adjust the sliding position of the movable plate, which pulls the first cam shaft through the connecting rod, causing the adjusting plate to slide on the surface of the first guide rail. A pair of ring-shaped clamps fix the surface of the lens body. The advantage of this is that it can adapt to the fixing needs of lens bodies of different thicknesses. When the lens body needs to be removed from between the pair of ring-shaped clamps, the screw rod is reversed, and the lens body detaches from the ring-shaped clamps. Under the action of gravity, it falls into the storage slot for protection. The advantage of this is to prevent the lens body from being damaged. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4A lens holding mechanism includes a fixed plate 1, a first guide rail 4 fixedly connected to the upper surface of the fixed plate 1, a pair of adjusting plates 11 slidably connected to the upper surface of the first guide rail 4, a lifting plate 5 fixedly connected to the upper surface of the adjusting plate 11, a circular clamping plate 6 fixedly connected to the surface of the lifting plate 5, a lens body 7 disposed between the pair of circular clamping plates 6, and a clamping and positioning mechanism disposed on the surface of the fixed plate 1.

[0021] By setting the first guide rail 4, the sliding stability of the adjustment plate 11 is maintained. By setting the lifting plate 5, the circular clamping plate 6 is driven to move. The circular clamping plate 6 clamps and positions the lens body 7. By setting the clamping and positioning mechanism, lens bodies 7 of different thicknesses can be fixed, and the lens body 7 is prevented from being damaged when it is removed.

[0022] In this utility model, reference Figure 1 The clamping and positioning mechanism includes an L-shaped plate 3 fixedly connected to the surface of the fixed plate 1. A threaded rod 2 is threadedly connected to the inner wall of the L-shaped plate 3, and a movable plate 8 is rotatably connected to one end of the threaded rod 2.

[0023] By setting up an L-shaped plate 3, a supporting threaded rod 2 is installed. By setting up the threaded rod 2, the sliding position of the movable plate 8 can be adjusted by rotating the threaded rod 2.

[0024] In this utility model, reference Figure 3 The surface of the L-shaped plate 3 is fixedly connected to the second guide rail 12, the lower surface of the movable plate 8 is slidably connected to the surface of the second guide rail 12, and the upper surface of the adjusting plate 11 is fixedly connected to the first convex shaft 14.

[0025] By setting the second guide rail 12, the stability of the sliding of the movable plate 8 is ensured, and by setting the first convex shaft 14, the connecting rod 15 is installed.

[0026] In this utility model, reference Figure 3 The upper surface of the movable plate 8 is fixedly connected to a second convex shaft 13, and the surfaces of the first convex shaft 14 and the second convex shaft 13 are rotatably connected to the same connecting rod 15.

[0027] By setting a second cam shaft 13, when the second cam shaft 13 moves and changes position, it drives the connecting rod 15 to move. By setting the connecting rod 15, the overall position of the adjusting plate 11 can be changed by pushing and pulling.

[0028] In this utility model, reference Figure 2 and Figure 4 An arc-shaped plate 9 is fixedly connected to the upper surface of the fixing plate 1. A storage groove 16 is provided on the upper surface of the arc-shaped plate 9, and the storage groove 16 corresponds to the position of the lens body 7.

[0029] By providing a storage slot 16, when the lens body 7 is removed and falls between a pair of circular clamps 6, it falls into the storage slot 16 for protection.

[0030] In this utility model, reference Figure 2 and Figure 3 The inner wall of the ring-shaped clamp 6 has a groove 10, and the inner wall of the groove 10 is pressed against the surface of the lens body 7. The end of the threaded rod 2 away from the movable plate 8 is fixedly connected to a handwheel 17.

[0031] By setting the groove 10, space is provided for the lens body 7 to engage, and by setting the handwheel 17, the threaded rod 2 can be easily rotated.

[0032] Working principle: The lens body 7 is placed between a pair of circular clamping plates 6, so that the inner wall of the groove 10 is pressed against the surface of the lens body 7. Then, the operator turns the handwheel 17, which drives the threaded rod 2 to rotate. The rotation of the threaded rod 2 adjusts the sliding position of the movable plate 8, which drives the connecting rod 15 to move through the second convex shaft 13. The connecting rod 15 pulls the first convex shaft 14, causing the adjusting plate 11 to slide on the surface of the first guide rail 4, so that the pair of circular clamping plates 6 move closer to each other, keeping the lens body 7 pressed and fixed. When the lens body 7 needs to be removed from between the pair of circular clamping plates 6, the threaded rod 2 is reversed, the pair of circular clamping plates 6 move away, and the lens body 7 falls off under the action of gravity and falls into the storage groove 16 for protection, preventing the lens body 7 from being damaged.
