Description

Technical Field

[0001] The utility model relates to the field of dental instruments, in particular to a light shielding plate with a light intensity testing handle. Background Art

[0002] The curing light is a commonly used instrument in the dental field. When using the curing light, a light shield is used to protect medical staff and patients. The existing light shields are flat, which makes it difficult to block the scattered light. The light scattered into the environment is likely to affect the skin health and vision health of medical staff and patients. And because the electronic components of the curing light will decay every once in a while, which will cause its light intensity to weaken, it is necessary to ensure the light intensity when it is used. The existing solution is to have technicians conduct regular inspections. Therefore, if the light intensity index can be self-detected by the chair, it can better achieve the maintenance of the curing light and guarantee the clinical treatment effect. Utility Model Content

[0004] The utility model adopts the following technical solutions:

[0005] A light baffle with a light intensity test handle comprises a light baffle body, a test handle and a connecting piece, wherein the connecting piece is fixedly arranged on the light baffle body, the light baffle body is an arc-shaped structure, the test handle can be rotatably connected to the connecting piece, and a test area and a display are arranged on the test handle, the test area is used for light intensity testing, and the display is used for displaying test results.

[0006] Furthermore, a avoidance portion is formed at the top of the light-shielding plate body, the avoidance portion has the same thickness as the light-shielding plate body and is arched toward one side along the thickness direction, so that the avoidance portion and the light-shielding plate body enclose a avoidance space.

[0007] Furthermore, a baffle strip is provided on one side edge of the light baffle body close to the avoidance portion, and the baffle strip is made of a flexible material.

[0008] Furthermore, the connecting member includes a mounting portion and a circumferential connecting portion. The connecting member is fixedly connected to the light shielding plate body through the mounting portion.

The rotating disc 241 is inserted into the ring connection hole 32 so that the test handle 2 is rotatably connected to the connecting piece 3.

[0031] One side of the light shielding plate body 1 protrudes to form a mounting table 12. Two first through holes 120 and one screw hole 121 are formed on the mounting table 12. The two first through holes 120 are arranged on both sides of the screw hole 121. A guiding column 300 corresponding to the two first through holes 120 and a second through hole 301 corresponding to the screw hole 121 are formed on the mounting part 30.
