Description

Technical Field

[0001] This utility model relates to the field of optical multi-lens technology, specifically to an optical multi-lens distance adjustable structure. Background Technology

[0002] A lens is an optical element made of transparent material with a spherical surface. It can be widely used in various fields such as security, automotive, digital cameras, lasers, and optical instruments. During the production of lenses, it is necessary to test their refractive index, light transmittance, and other characteristics. Therefore, it is necessary to use equipment with adjustable spacing to test the relevant data.

[0003] Currently, utility model patent CN221426927U discloses an optical multi-lens distance adjustable structure, including a housing. A fixed lens is fixedly installed on the outer wall of one end of the housing. A transmission sleeve is fitted onto the outer wall of the housing. A threaded slider is fixedly connected to the transmission sleeve. A rotating groove is formed on the arc-shaped outer wall of the transmission sleeve. A rotating ring is fitted onto the inner surface of the rotating groove. A movable lens is fixedly installed on the arc-shaped outer wall of the rotating ring. A protective mechanism is provided on the outer wall of the transmission sleeve. By providing a protective mechanism, during the performance testing of the movable lens, the baffles on both sides of the movable lens, when rotated to the side of the housing, will re-shield and protect both sides of the movable lens due to the influence of the arc-shaped groove and the transmission sleeve. This prevents the movable lens from being damaged by the external environment during use and replacement testing, thus affecting the accuracy of the device's test results.

[0004] However, in actual use, when the above-mentioned equipment is dropped or bumped, although it has a certain shielding and protection capabilities, it is easy for the moving lens and the moving ring to break and separate, resulting in poor protection. Moreover, the operation of switching the moving lens for testing is relatively cumbersome. Therefore, we propose an optical multi-lens distance adjustable structure. Utility Model Content

[0029] Example 1

[0030] Please see Figures 1-8 As shown, this utility model provides a technical solution: an optical multi-lens distance adjustable structure, including a movable ring 14 sliding on the outer surface of a housing 1, an adjusting screw 9 passing through the right side of the housing 1 via a bearing connected to the inner side of the housing 1, an adjusting block 2 fixedly connected to the right side of the adjusting screw 9, a movable sleeve 22 threadedly connected to the outer surface of the adjusting screw 9, a limiting slider 23 sliding on the inner surface of the housing 1 fixedly connected to the top and bottom of the movable sleeve 22, and one side of the limiting slider 23 fixedly connected to the inner wall of the movable ring 14, a protective cover 8 fixedly connected to the outer side of the movable ring 14, a rotating ring 18 located inside the protective cover 8 provided at the left end of the outer surface of the movable ring 14, a transmission frame 19 fixedly connected to the outer side of the rotating ring 18, a plurality of guide blocks 20 distributed at equal angles fixedly connected to the right side of the transmission frame 19, and the guide blocks 20 being adapted to the end of the adjusting member 24 near the rotating rod 27, and the outer side of the transmission frame 19 being... Multiple movable lens bodies 13 are fixedly installed on the side at equal angles. Multiple drive grooves 21 corresponding to the movable lens bodies 13 are opened on the right side of the transmission frame 19. A rotating rod 27 is movably connected to the front end of the right side of the protective cover 8. A rotating block 7 is fixedly connected to the right side of the rotating rod 27. An adjusting component 24 is fixedly connected to the left side of the rotating block 7. A driving pin block 25 sliding in the drive groove 21 is fixedly connected to one end of the left side of the adjusting component 24. A concave hole 28 is opened at the front end of the rotating block 7 near the rotating rod 27. A return spring 29 is fixedly connected to the inside of the concave hole 28. A positioning rod 26 is fixedly connected to one end of the return spring 29. A hemispherical recess 17 is opened at the front end of the right side of the protective cover 8. The left end of the positioning rod 26 is a hemisphere and is adapted to the hemispherical recess 17. A fixed lens 5 is fixedly installed at the left end of the top of the housing 1. A test notch 15 is opened at the middle of the top of the protective cover 8.

[0031] This technical solution: By setting up the protective cover 8, multiple movable lens bodies 13 installed on the outside of the transmission frame 19 can be externally protected, preventing breakage between the movable lens body 13 and the transmission frame 19 in the event of a collision or fall. When the adjusting block 2 drives the adjusting screw 9 to rotate, the movable sleeve 22 can move left and right on the outer surface of the adjusting screw 9. When the movable sleeve 22 moves, it can drive the movable ring 14 to move synchronously via the limiting slider 23. Thus, the distance between the movable lens body 13 and the fixed lens 5 can be quickly adjusted when the fixed lens 5 is in a fixed position, which is convenient for the tester. When it is necessary to switch the movable lens body 13, the rotating block 7 drives the rotating rod 27 and the adjusting part 24 to rotate. When the rotating block 7 rotates one revolution, the positioning latch 26 will disengage from the hemispherical recess 17 and compress the return spring 29 in the recess 28. When the positioning rod 26 is engaged again in the hemispherical recess 17, it can limit the position of the rotating block 7 after one revolution. When the adjusting member 24 rotates with the rotating rod 27, the adjusting member 24 will drive the driving pin 25 to slide out of one driving groove 21 and into another adjacent driving groove 21. With the continued rotation of the adjusting member 24, the driving pin 25 can drive the transmission frame 19 and the rotating ring 18 to slide on the outer surface of the housing 1 at the interval angle of the two adjacent driving grooves 21, so that the driving groove 21 into which the driving pin 25 enters can cover the position of the driving groove 21 from which the previous driving pin 25 exited. This allows the movable lens body 13 corresponding to the driving groove 21 to be quickly moved to the test notch 15 for use. When the rotating block 7 is rotated one or more revolutions, the movable lens body 13 can be quickly switched, which is convenient and quick to use.
