It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example

[0020] For acrylic sheet light transmittance testing equipment, please refer to [reference needed]. Figure 1 - Figure 4 The system includes a workbench 1 and a light source plate 2. The top of the workbench 1 has an inner groove 6. A U-shaped support frame 7 is fixedly connected to the inner side wall of the inner groove 6. An acrylic plate body 4 is fixedly connected to the top of the U-shaped support frame 7 inside the inner groove 6. A light signal receiver 8 that can receive light source signals is placed at the bottom of the inner groove 6. An auxiliary mechanism 5 that drives the light source plate 2 to make arc-shaped movements is provided at the top of the workbench 1.

[0021] It should be noted that a light signal receiver 8 is placed at the bottom of the inner groove 6 to receive light source signals, which is used to accurately capture the light passing through the acrylic sheet body 4, thereby calculating the light transmittance. An auxiliary mechanism 5 is also set at the top of the worktable 1 to drive the light source plate 2 to make arc-shaped movements, so that the light source plate 2 can move in an arc-shaped trajectory during the test, simulating the light transmittance under different angles of light, improving the comprehensiveness and accuracy of the test. Through the arc-shaped movement of the auxiliary mechanism 5, the light transmittance performance of the acrylic sheet body 4 under different light angles can be observed more intuitively, providing strong data support for subsequent product optimization and quality control.

[0022] Please refer to Figure 3 and Figure 4 The auxiliary mechanism 5 includes symmetrically arranged sliding grooves 3 on the top of the worktable 1, located on both sides of the inner groove 6. A semi-circular toothed ring 51 is slidably sleeved at the top of the worktable 1, located at the position of the sliding groove 3. A stand 53 is provided at the top of the toothed ring 51. Guide grooves 52 are symmetrically arranged on the outer side wall of the toothed ring 51. The auxiliary mechanism 5 also includes a drive motor 54 fixedly connected to the outer side wall of the stand 53. A drive shaft 541 is fixedly connected to the output end of the drive motor 54. A gear 55 that meshes with the toothed ring 51 is rotatably sleeved on the inner side wall of the stand 53. The drive shaft 541 passes through the stand 53 and is fixedly connected to the center of the gear 55.

[0023] It should be noted that a semi-circular toothed ring 51 is slidably fitted at the top of the worktable 1, located at the position of the slide groove 3. The shape design of the toothed ring 51 allows it to slide in an arc along the slide groove 3, thereby driving the light source plate 2 to achieve arc-shaped movement. A stand 53 is provided at the top of the toothed ring 51, providing mounting support for components such as the drive motor 54 and gear 55. The output end of the drive motor 54 is fixedly connected to the drive shaft 541. Through the rotation of the drive shaft 541, power is transmitted to subsequent components. The inner side wall of the stand 53 is rotatably fitted with a gear 55 that meshes with the toothed ring 51, realizing the conversion of the motor's rotational power to the arc-shaped sliding of the toothed ring 51. Furthermore, the drive shaft 541 passes through the stand 53 and is fixedly connected to the center of the gear 55, ensuring the effective transmission of driving force.

[0024] Please refer to Figure 3 and Figure 4 The outer side wall of the support frame 53 is symmetrically and fixedly connected with an arc-shaped rod 56. The end of the arc-shaped rod 56 is fixedly connected with a guide rod 561, and the guide rod 561 is slidably sleeved inside the guide groove 52. The bottom end of the support frame 53 is symmetrically and fixedly connected with a U-shaped frame 57. The U-shaped frame 57 is slidably sleeved inside with a telescopic frame 571 fixedly connected to the top of the light source plate 2. The outer wall of the U-shaped frame 57 is inserted with a pin 572 for limiting the telescopic frame 571.

[0025] It should be noted that a guide rod 561 is fixedly connected to the end of the arc-shaped rod 56, and the guide rod 561 is slidably sleeved inside the guide groove 52. This allows the guide rod 561 to slide correspondingly within the guide groove 52 when the toothed ring 51 slides along the slide groove 3 in an arc shape. This ensures that the stand 53 can stably follow the movement trajectory of the toothed ring 51, further improving the stability and accuracy of the arc-shaped movement of the light source plate 2. A U-shaped frame 57 is symmetrically fixedly connected to the bottom end of the stand 53. The design of the U-shaped frame 57 facilitates the installation and adjustment of the light source plate 2. A telescopic frame 571, which is fixedly connected to the top end of the light source plate 2, is slidably sleeved inside the U-shaped frame 57. This structure allows the position of the light source plate 2 to be adjusted up and down according to the test requirements, thereby adapting to the testing of acrylic sheet bodies 4 of different thicknesses or sizes. After the position of the light source plate 2 is adjusted, the telescopic frame 571 can be effectively prevented from sliding or shifting during the test by inserting the plug pin 572, ensuring the accuracy and reliability of the test.

[0026] Please refer to Figure 1 and Figure 4 The upright frame 53 is composed of two separate connecting plates, and the four corners on the opposite side of the two connecting plates are connected by a connecting shaft for limiting. The four corners of the bottom end of the worktable 1 are all fixedly connected with support rods.

[0027] It should be noted that the four corners of the two connecting plates on opposite sides are connected by connecting shafts for limiting. This connection method not only ensures the overall stability of the upright 53, but also allows it to be finely adjusted or adapted to deformation within a certain range, so as to better cope with various situations during the test. The four corners of the bottom end of the workbench 1 are fixedly connected with support rods. These support rods provide solid and reliable support for the workbench 1, ensuring its stability and load-bearing capacity during the test.

[0028] Working principle: The auxiliary mechanism 5 slides a semi-circular toothed ring 51 through a symmetrically opened groove 3 at the top of the worktable 1. A support frame 53 is provided at the top of the toothed ring 51. The support frame 53 consists of two separate connecting plates connected by a connecting shaft, ensuring structural stability and flexibility. The drive motor 54 is fixed to the outer wall of the support frame 53, and its output end is connected to a gear 55 on the inner wall of the support frame 53 via a drive shaft 541. When the drive motor 54 starts, the drive shaft 541 rotates, driving the gear 55 to rotate. The gear 55 meshes with the toothed ring 51, causing the toothed ring 51 to move in an arc along the groove 3. Simultaneously, an arc-shaped rod 56 is symmetrically fixed to the outer wall of the support frame 53, and the end of the arc-shaped rod 56 is provided with a guide... The guide rod 561 is slidably sleeved inside the guide groove 52 on the outer wall of the toothed ring 51, ensuring that the upright frame 53 can stably follow the movement trajectory of the toothed ring 51 in an arc-shaped movement. A U-shaped frame 57 is symmetrically fixedly connected to the lower end of the upright frame 53. A telescopic frame 571, fixedly connected to the top of the light source plate 2, is slidably sleeved inside the U-shaped frame 57. By adjusting the length of the telescopic frame 571, the distance between the light source plate 2 and the acrylic plate body 4 can be changed. A limiting pin 572 for the telescopic frame 571 is inserted into the outer wall of the U-shaped frame 57 to ensure that the telescopic frame 571 remains stable in the adjusted position. When the auxiliary mechanism 5 drives the light source plate 2 in an arc-shaped movement, the light source illuminates the acrylic plate body 4 at different angles. The light signal receiver 8 is located at the inner bottom end of the inner groove 6 and can receive the light source signal transmitted through the acrylic plate body 4.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
