[0003] Currently, after the diffuser plate is manufactured, its light transmittance needs to be tested. When producing PC diffuser plates, the light transmittance of the diffuser plate needs to be balanced to achieve the desired effect. When mass-producing diffuser plates, random checks of the entire diffuser plate are required.
[0004] However, the traditional diffusion plate testing fixture currently available on the market has an insufficiently optimized structure and an unreasonable design. Utility Model Content
[0005] The purpose of this invention is to provide a diffusion plate testing fixture to solve the problems mentioned in the background art.

[0007] A diffuser plate testing fixture includes a base, a fixture seat fixedly connected to the rear of the upper surface of the base, a top plate fixedly connected to the top of the fixture seat, a first track fixedly connected to the top of the top plate, a sliding table slidably connected to the upper part of the first track, a fixed plate slidably connected to the upper part of the sliding table, a support frame fixedly connected to the front end of the upper surface of the fixed plate, a front plate fixedly connected to the front end of the support frame, an adjustment assembly provided on the left side of the front facade of the front plate, a vertical bar fixedly connected to the right side of the front facade of the front plate, and a lighting lamp installed on the lower part of the front facade of the vertical bar.
[0008] As a further embodiment of this utility model: the adjustment assembly includes a motor, the drive end of the motor is fixedly connected to a rotating shaft, the bottom of the motor is fixedly connected to a bottom frame, and the bottom frame is fixedly connected to the left side of the front facade of the front panel.
[0009] As a further improvement of this utility model: a bearing seat is installed in the center of the inner frame of the bottom frame, and an L-shaped connector is fixedly connected to the bottom of the rotating shaft.
[0010] As a further improvement of this utility model: a mounting plate is fixedly connected to one side of the vertical plate of the L-shaped connector, and a detection plate is installed on the side of the mounting plate.
[0011] As a further embodiment of this utility model: a base plate is fixedly connected to the upper surface of the base, a plate frame is fixedly connected to the upper surface of the base plate, and through holes are opened at the front and back of the plate frame, and light-transmitting plates are installed at the through holes. An inner groove is opened on one side of the plate frame.
[0012] As a further improvement of this utility model: an inner plate is inserted into the groove opening of the inner groove, and a diffuser plate is installed on the upper surface of the inner plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this utility model, when the motor rotates, the shaft drives the eccentrically connected L-shaped connector to rotate, causing the mounting plate connected to the vertical plate of the L-shaped connector to rotate to the front of the frame. The light illuminates the diffuser plate inside the frame, and the light shines through the diffuser plate onto the light-transmitting plate, which then illuminates the detection plate mounted on one side of the mounting plate for light source detection. The sliding table and the fixed plate can be manually pushed to adjust the support frame forward and backward as well as left and right, and to replace the detection plate and the light. Its structure is more optimized and its design is more reasonable. Attached Figure Description
