[0002] After the computer display screen is produced, it is necessary to inspect the appearance of the computer display screen to see if there are any defects or dirt attached to the computer display screen.

[0003] Currently, when inspecting the appearance of a computer display screen, the computer display screen is placed under a light bar, which illuminates the computer display screen for auxiliary lighting, and the appearance of the computer display screen is inspected by the human eye. However, the illumination angle of the existing inspection spotlight is fixed and cannot be adjusted according to the inspection conditions, so further improvement is needed. Utility Model Content

[0004] In order to facilitate adjustment of the illumination angle of a detection spotlight, the present application provides a detection spotlight for a computer screen.

[0005] The present application provides a computer screen detection spotlight that adopts the following technical solution:

[0006] A detection spotlight for a computer screen includes a detection bracket and a spotlight body.

A light exit window is provided on one side of the lamp box, and the detection bracket is provided with an adjustment component for adjusting the rotation angle of the lamp box.

[0007] By adopting the above technical solution, when inspecting the appearance of a computer screen, the computer screen is placed under the spotlight body, and the rotation angle of the lamp box is adjusted by adjusting the component, thereby adjusting the irradiation angle of the light outlet window on the lamp box to meet the inspection requirements of different inspection conditions.

[0008] Preferably, the lamp box is provided with a transparent light guide plate for sealing the light exit window.

[0009] By adopting the above technical solution, a transparent light guide plate is added to seal the light exit window on the lamp box, reducing the possibility of dust entering the lamp box through the light exit window, thereby reducing the possibility of dust adhering to the surface of the light strip and improving the cleanliness of the light strip surface.

[0010] Preferably, the detection bracket includes a detection base plate and a pair of detection side plates fixedly connected to both sides of the detection base plate, and the lamp box is rotatably connected to the upper portion of the detection side plates.

[0011] By adopting the above technical solution, the lamp box is rotatably connected to the upper part of the detection side plate, so that a space for placing the computer display screen is formed between the lamp box and the detection bottom plate.

[0012] Preferably, the detection side panel is provided with a mounting hole, and the adjustment assembly includes an adjustment screw passing through the mounting hole and threadedly connected to the end face of the lamp box, and an adjustment knob located outside the detection side panel and coaxially fixedly connected to the end face of the adjustment screw, and the end face of the adjustment knob is pressed against the outer wall of the detection side panel.

[0013] By adopting the above technical solution, when it is necessary to adjust the rotation angle of the lamp box, the adjusting screw is loosened by turning the adjusting knob so that the adjusting screw is rotated toward the outside of the detection side plate, so that the end face of the adjusting knob is separated from the detection side plate, and the illumination angle of the lamp box can be adjusted by rotating. After the adjustment is completed, the adjusting screw is tightened so that the adjusting screw is rotated toward the lamp box, so that the end face of the adjusting knob is pressed against the outer wall of the detection side plate, thereby limiting the rotation of the lamp box in the form of damping. The structure is simple and the adjustment is convenient.

[0014] Preferably, a through hole is formed on the end surface of the lamp box, a screw sleeve is fixedly connected to the inner end surface of the lamp box, the adjusting screw is passed through the through hole and the screw sleeve is threadedly passed through.

[0015] By adopting the above technical solution, the threaded connection between the lamp box and the adjusting screw is achieved by fixing the screw sleeve, and there is no need to open a threaded hole on the outer wall of the lamp box, so that the wall of the lamp box can be made thinner and the overall weight of the lamp box is reduced.

[0016] Preferably, the adjusting screw sleeve is provided with a first resistance-increasing gasket located between the adjusting knob and the detection side plate and a second resistance-increasing gasket located between the detection side plate and the end face of the lamp box, and the first resistance-increasing gasket and the second resistance-increasing gasket are respectively pressed against the outer wall and the inner wall of the detection side plate.

[0017] By adopting the above technical solution, a first resistance-increasing gasket and a second resistance-increasing gasket are additionally provided to increase the friction damping between the end face of the adjustment knob / the outer wall of the lamp box and the detection side plate.

[0018] Preferably, the mounting hole is a strip-shaped hole, and the length direction of the mounting hole is vertically arranged.

[0019] By adopting the above technical solution, the mounting hole is set as a strip hole, which facilitates the sliding of the adjustment screw on the mounting hole, thereby realizing the height adjustment of the lamp box to meet the detection requirements of different detection conditions.

[0020] Preferably, the side wall of the lamp box is provided with heat dissipation holes.

[0021] By adopting the above technical solution, the heat generated by the light strip during operation is discharged from the heat dissipation holes, thereby reducing the heat accumulation in the inner cavity of the light box.

[0022] Preferably, the lamp box has a built-in fan.

[0023] By adopting the above technical solution and adding a fan, the heat dissipation efficiency of the lamp box is improved.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. When inspecting the appearance of a computer screen, place the computer screen under the spotlight body and adjust the rotation angle of the lamp box through the adjustment component to adjust the irradiation angle of the light outlet window on the lamp box to meet the inspection requirements of different inspection conditions;

[0026] 2. A transparent light guide plate is added to seal the light exit window on the lamp box, reducing the possibility of dust entering the lamp box from the light exit window, thereby reducing the possibility of dust adhering to the surface of the light strip and improving the cleanliness of the light strip surface;

[0027] 3. The mounting hole is a strip hole, which is convenient for adjusting the screw to slide on the mounting hole, thereby realizing the height adjustment of the lamp box to meet the detection requirements of different detection conditions. BRIEF DESCRIPTION OF THE DRAWINGS
