Description

Technical Field

[0001] This utility model relates to the field of light-shielding sheet processing technology, and in particular to a portable light-shielding sheet testing device. Background Technology

[0002] A light-blocking plate is an optical element used to control the amount of light. When external light passes through the light-blocking plate, unwanted light is blocked from entering, thus blocking light. The light-blocking plate is located between two lenses and is used to block excess light to prevent stray light and improve the shooting effect of electronic devices.

[0003] Currently, during the production process of light-shielding sheets, random inspections are required. These inspections typically involve using special illumination lamps to observe the sheets' performance and assess their quality. However, current refraction lamps and their frames are bulky and usually fixed in one position, making it inconvenient for operators to perform random inspections. Furthermore, the angle adjustment remains constant during use, failing to meet the needs of positional adjustments. Therefore, we have proposed a portable light-shielding sheet inspection device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable light-shielding sheet detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable light-shielding sheet detection device includes a carrier plate. Support legs are movably connected to the four corners of the lower end of the carrier plate. Rollers are rotatably connected to the lower ends of the support legs. A sliding groove is provided on one side of the upper end of the carrier plate, and a slider is installed within the groove. A movable plate is fixed to the upper end of the slider, and a rotating plate is rotatably connected to the upper end of the movable plate. A fixed frame is rotatably connected to the other side of the upper end of the carrier plate. A rotating rod is rotatably connected to the fixed frame. A pull rod is rotatably connected to one end of the rotating rod, and a detection lamp is detachably connected to the lower end of the pull rod. Two support rods are fixed to one side of the fixed frame, and the support rods correspond to the detection lamps. One side of the rotating plate is rotatably connected to the fixed frame. Three limiting rings are fixed at equal intervals on one side of the rotating plate. An L-shaped insertion rod is rotatably connected to one side of the lower end of the fixed frame, and one end of the L-shaped insertion rod is inserted into one of the limiting rings.

[0007] Preferably, the lower end of the bearing plate is provided with a second threaded blind hole at each of the four corners, and the upper end of the support leg is fixed with a second stud, and a second stud on the same side is threaded into a second threaded blind hole on the same side.

[0008] Preferably, a limiting groove is provided on one side of the slide groove, a limiting block is fixed on one side of the slider, and the limiting block is installed in the limiting groove, and a notch is provided on one side of the upper end of the limiting groove.

[0009] Preferably, the lower end of the pull rod is provided with a first threaded blind hole, and the upper end of the connecting rod is fixed with a first stud, the first stud being threaded into the first threaded blind hole.

[0010] Preferably, the fixing frame is U-shaped.

[0011] Preferably, the upper four corners of the support plate are provided with mounting holes.

[0012] In this invention, when a light-shielding sheet needs to be randomly inspected, the roller drives the carrier plate to the corresponding position, the slider is moved to the corresponding position, and the L-shaped plug is inserted into the corresponding limiting ring. Then, the rotating rod is rotated to adjust the height. The pull rod makes it easy to adjust the detection lamp to the corresponding angle and position before inspection. When temporary random inspection is required, the detection lamp can be unscrewed off using the connecting rod for carrying and inspection. Alternatively, the entire device can be fixed in one position for long-term use. After use, one end of the L-shaped plug is pulled out from the limiting ring, the slider is moved into the notch and then pulled out. The rotating plate and the fixing frame are laid down, and the pull rod is folded to one end of the rotating rod, so that the detection lamp is placed on the support rod, realizing the retraction of the entire mechanism.

[0013] This invention not only enables the movement and adjustment of the light-shielding sheet inspection mechanism, but also allows for convenient retraction and placement, reducing space occupation. Furthermore, it allows for easy disassembly and inspection as needed, greatly improving the flexibility and sufficiency of the inspection process. This meets the inspection requirements during the production of light-shielding sheets and enhances practicality and flexibility. Attached Figure Description
