Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6This utility model provides a technical solution: a fixed structure for optical lens testing, including a testing platform 1. The upper surface of the testing platform 1 is rotatably connected to an angle adjustment device 2 along the Y-axis via two connecting brackets 11. The angle adjustment device 2 includes two support components 21. Each of the two support components 21 has a rotating component 22 at one end close to each other. The rotating component 22 rotates along the Z-axis. The rotating component 22 includes a T-shaped slider 5 with an arc structure. A clamping component 23 is fixedly connected to the inner wall of the T-shaped slider 5. The clamping component 23 includes a first connecting rod 231 and a second connecting rod 232 that are slidably connected to each other. The end of the second connecting rod 232 is engaged with a pressing block 24 that abuts against the lens.

[0023] Specifically, by setting an angle adjustment device 2 that rotates along the Y-axis, the angle adjustment device 2 includes two support components 21, and a rotating component 22 that rotates along the Z-axis is set between the two support components 21, so that after the lens is placed between the rotating components 22, the lens can be adjusted to different angles and positions through the cooperation of the rotating components 22 and the angle adjustment device 2, thereby realizing convenient and comprehensive testing of the lens.

[0024] By providing a clamping assembly 23, which includes a first link 231 and a second link 232 that are slidably connected to each other, and a first spring 233 between the first link 231 and the second link 232, the clamping assembly 23 can adapt to the curvature of the lens when the lens is squeezed and fixed, and can also buffer the squeezing force under the action of the spring to avoid excessive squeezing force and damage to the edge of the lens.

[0025] The angle adjustment device 2 includes a connecting shaft 4, and the support assembly 21 includes an arc-shaped block 6. The inner side of the arc-shaped block 6 is provided with a T-shaped groove 61 that cooperates with the T-shaped slider 5. A limiting device 7 for controlling the rotation angle of the T-shaped slider 5 is provided in the T-shaped groove 61.

[0026] Specifically, both the T-shaped slider 5 and the T-shaped groove 61 are T-shaped structures. The arc-shaped block 6 and the T-shaped groove 61 of the T-shaped structure cooperate with each other, so that the two can be stably connected together and can also rotate around the Z-axis. The limiting device 7 increases the friction between the two, so that the mutual support will not rotate during normal use.

[0027] The T-shaped groove 61 has a receiving cavity 62. The limiting device 7 includes a limiting block 71 that is slidably disposed in the receiving cavity 62. The surface of the T-shaped slider 5 has a limiting groove 53 that abuts against the limiting block 71. A second spring 72 is disposed in the receiving cavity 62. The two ends of the second spring 72 are fixedly connected to the receiving cavity 62 and the limiting block 71, respectively.

[0028] Specifically, the second spring 72 drives the limiting block 71 to abut against the limiting groove 53, thereby increasing the friction force when the arc-shaped block 6 rotates.

[0029] One of the connecting shafts 4 includes two shafts 41. One shaft 41 is fixedly connected to a rectangular rod 42 at one end near the other shaft 41. The end of the rectangular rod 42 extends into the other shaft 41 and is slidably connected to it. The other shaft 41 is threaded with a locking bolt 43. The end of the locking bolt 43 extends into one of the shafts 41 and abuts against the rectangular rod 42.

[0030] Specifically, the two shafts 41 are slidably connected to each other under the guidance of the rectangular rod 42, so that one rotating component 22 can be driven to move closer to the other rotating component 22. With the clamping action of the clamping component 23, the lens is squeezed and fixed. The locking bolt 43 fixes the sliding position of the rectangular rod 42, so that the rectangular rod 42 will not slide arbitrarily during the test. A third spring is provided between the rectangular rod 42 and the other shaft 41. When the third spring is in normal state, it drives one rotating component 22 to automatically move closer to the other rotating component 22, so as to realize the automatic clamping and fixing of the lens.

[0031] Both ends of the two T-shaped sliders 5 are fixedly connected to extension plates 51. One of the extension plates 51 is fixedly connected to a guide rod 52 on its side. The end of the guide rod 52 passes through the extension plate 51 on the other T-shaped slider 5 and is slidably connected to it.

[0032] Specifically, the guide rod 52 guides the direction of the two T-shaped sliders 5 as they slide closer to each other, so that they can stably contact the lens.

[0033] A locking block 25 is fixedly connected to the side of the compression block 24. The end of the second connecting rod 232 is provided with a locking groove 234 that matches the locking block 25. A first spring 233 is provided between the first connecting rod 231 and the second connecting rod 232. The two ends of the first spring 233 are fixedly connected to the first connecting rod 231 and the second connecting rod 232 respectively.

[0034] Specifically, the compression block 24 is a rubber block with a relatively soft material, so that it will not damage the lens when it comes into contact with the lens. The cooperation of the locking block 25 and the slot 234 allows the compression block 24 to be easily replaced and installed. The side of the connecting bracket 11 is threaded with an adjustment component 3, which is a knob. The end of the knob passes through the connecting bracket 11 and is fixedly connected to one of the connecting shafts 4.
