Description

Technical Field

[0001] The utility model relates to the technical field of polarizer testing, in particular to a tension testing device suitable for polarizers. Background Art

[0002] The reason why polarized light is called polarized light is that the polarized light facing the eyes of ordinary LCD is frosted to dissipate surface reflections and scatter light to increase the viewing angle of the LCD. For projectors, any scattering will cause light loss. The ideal state of the LCD used in projectors should be 0 degree viewing angle, that is, there will be no light when looking at the LCD from a vertical direction. Polarized light needs to be tensile tested during the production process, so corresponding tensile testing equipment is needed.

[0003] Most of the tensile testing equipment suitable for polarizers in the prior art can only perform long-term tensile testing on polarizers, and thus cannot perform tensile testing on polarizers in an intermittent cycle, and thus cannot make the polarizers deform repeatedly and then recover, which results in certain limitations in the testing effect on the polarizers and is not conducive to use.

[0004] Therefore, there is a need for a tensile testing device suitable for polarizers to solve the problem in the prior art that the polarizer cannot be tested intermittently and cyclically, so that the polarizer cannot be repeatedly deformed and then restored, which limits the testing effect of the polarizer.

A spring 11 is sleeved on the outer circumferential surface of the inner part of the adjacent position slide groove 5, one side of the spring 11 is fixed to the inner wall of the adjacent position slide groove 5, and the other side of the spring 11 is fixed to the surface of the adjacent position slider 6. The rotating disk 3 is rotated, so that the distance between the two groups of connecting plates 20 can be changed under the interference between the rotating disk 3 and the arc block 9, and the arc block 9 can be embedded in the interior of the adjacent position arc groove 8 under the action of the rebound force of the spring 11, so that the distance between the two groups of connecting plates 20 can be deformed intermittently and cyclically, so as to perform intermittent tensile test on the polarizer fixed between the two groups of connecting plates 20, thereby improving the application scope of the device.

[0024] Please refer to Figure 1 and Figure 3 As shown, a movable rod 4 is fixed to the bottom of the rotating disk 3, and the surface of the bottom of the movable rod 4 is rotatably connected to the bottom of the inner wall of the inner warehouse 2. The surface of one end of the base 1 rotates a movable shaft 14, and the movable shaft 14 is located at the outer part of the base 1. The outer circumferential surface of the movable shaft 14 is fixedly sleeved with a handle 15, and one end of the movable shaft 14 extends to the inner cavity position of the inner warehouse 2. The outer circumferential surface of the movable shaft 14 extending to the inner cavity position of the inner warehouse 2 is fixedly sleeved with a first bevel gear 16, and the outer circumferential surface of the movable rod 4 is fixedly sleeved with a second bevel gear 17 near the first bevel gear 16. The first bevel gear 16 and the second bevel gear 17 are meshingly connected. The movable shaft 14 can be rotated by rotating the handle 15, so that the first bevel gear 16 can be rotated, so that the movable rod 4 can be rotated under the meshing action between the first bevel gear 16 and the second bevel gear 17.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3As shown, the inner circumference of the inner bin 2 is provided with two annular grooves 12, and a limiting ring 13 is slidably inserted inside the annular groove 12. The inner circumference of the limiting ring 13 is fixed to the outer circumference of the rotating disk 3. Since the limiting ring 13 is limited by the inner cavity surface of the adjacent annular groove 12, the movement trajectory of the limiting ring 13 can be limited, so that the rotating disk 3 can be in a stable state when rotating.

[0026] Example 2

[0027] Further in the embodiments, please refer to Figure 4 and Figure 5 As shown, a threaded rod 18 is rotatably connected to the inner surface of the connecting frame 7, and the upper and lower ends of the outer circumference of the threaded rod 18 are threadedly connected with symmetrically distributed threaded sleeves 19, and a connecting plate 20 is fixed to the surface of one end of the threaded sleeve 19, and a clamping plate 21 is inserted into the interior of the connecting plate 20, and a plurality of insertion holes 22 are evenly opened on the surface at the middle position of the clamping plate 21, and a bolt 23 is threadedly connected to one end of the connecting plate 20, and one end of the bolt 23 extends to the inside of the adjacent insertion hole 22. When the threaded rod 18 is rotated, the threaded sleeve 19 can be affected by the resistance and limitation of the connecting frame 7 on it, and the external thread structures at the upper and lower ends of the outer circumference of the threaded rod 18 are set in opposite directions, so that the spacing between the two connecting plates 20 can be adjusted, so that the two clamping plates 21 can clamp and fix the polarizer, and the length between the clamping plate 21 and the connecting plate 20 can be adjusted by the bolt 23 extending to the inside of the adjacent insertion hole 22, so that polarizers of different lengths can be fixed.

[0028] Please refer to Figure 4 and Figure 5 As shown, a T-shaped support groove 24 is provided on the inner surface of the connecting plate 20, and a T-shaped limiting strip 25 is inserted inside the supporting groove 24. One end of the limiting strip 25 passes through the supporting groove 24 and is fixed to the surface of the adjacent clamping plate 21. When the length between the clamping plate 21 and the connecting plate 20 is adjusted, the clamping plate 21 is supported by the limiting strip 25 and the supporting groove 24 to limit the movement trajectory of the clamping plate 21, and can prevent the distance between the clamping plate 21 and the connecting plate 20 along the vertical direction from changing when sliding.

[0029] Working principle: In actual use, when the user needs to perform a tensile test on the polarizer, the bolt 23 is rotated to extend it out of the adjacent position socket 22, so that the total length of the connecting plate 20 and the clamping plate 21 can be adjusted. When the adjustment is completed and it can adapt to polarizers of different lengths, the bolt 23 is rotated again to extend it to the adjacent position socket 22 to fix the clamping plate 21. When the threaded rod 18 is subsequently rotated, the threaded sleeve 19 can be affected by the resistance and limitation of the connecting frame 7 and the external thread structures at the upper and lower ends of the outer circumference of the threaded rod 18 are set in opposite directions. Therefore, the threaded sleeve 19 can clamp and fix the two sides of the polarizer under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 19 and the external thread structure of the outer circumference of the threaded rod 18. At this time, the arc block 9 is embedded in the adjacent position arc groove 8, so that the movable shaft 14 can rotate when the sleeve handle 15 is rotated. , so that the first bevel gear 16 can rotate, so that the movable rod 4 can rotate under the meshing action between the first bevel gear 16 and the second bevel gear 17, so that the rotating disk 3 can rotate, so that the inner cavity surface of the arc groove 8 can contact the arc block 9 until the outer peripheral surface of the rotating disk 3 contacts the arc block 9, so that the sliding rod 10 can stretch the adjacent position spring 11 and increase the spacing between the two connecting frames 7, thereby increasing the spacing between the two groups of connecting plates 20 to test the stretching of the polarizer, and when the next arc groove 8 moves to a position close to the arc block 9, the connecting frame 7 can be embedded in the arc groove 8 under the action of the rebound force of the spring 11, so that the spacing between the two connecting plates 20 is restored to the initial spacing, and under the continuous rotation of the rotating disk 3, the polarizer clamped by the two groups of connecting plates 20 can be subjected to intermittent cyclic tension testing.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
