Lamp housing provided with lamp fall-preventing and dimming mechanism

Abstract

The invention provides a lamp housing provided with a lamp fall-preventing and dimming mechanism. The lamp housing is composed of an adjustment screw hole (1), an airtight sinking table hole (2), an adjustment support (3), a guide hole (4), a receding device (5) and an anti-rotation groove (6). The anti-rotation groove (6) is matched with a guide column of a ball fixing buckle. The receding device (5) is designed to determine the deflection angle allowed when a part is prearranged. The adjustment support (3) is used for assisting a screwdriver in adjustment of a gear. The lamp housing provided with the lamp fall-preventing and dimming mechanism is characterized in that the adjustment screw hole (1) and the airtight sinking table hole (2) are located in the same straight line, and the coaxiality between the adjustment screw hole (1) and the airtight sinking table hole (2) is ensured. According to the lamp housing provided with the lamp fall-preventing and dimming mechanism, the chamfered bottom of the guide column of the ball fixing buckle makes contact with the bottom of the guide hole of the lamp housing, so that extreme positioning under the dimming condition is achieved. The lamp housing provided with the lamp fall-preventing and dimming mechanism has the characteristics that dimming is stable, machining is easy, and the range between the upper adjustment extreme and the lower adjustment extreme is wide.

Description

technical field [0001] The invention belongs to the manufacturing field of auto parts, and is used for a lamp housing of an anti-off dimming mechanism of an auto lamp. Background technique [0002] Automobile signal lights are an important signal tool to ensure the safe driving of automobiles and avoid traffic accidents. Car signal lights include turning lights, brake lights and small lights. Sometimes small lights also serve as fog lights. measures to avoid traffic accidents. The installation of the signal light needs a bracket. For different models, the installation methods of the lamps are different, so the installation angles of the lamps are also different. If you use the same installation bracket, you need this bracket to have strong adaptability. It can be adapted to various installation methods, but the existing installation brackets with high adaptability have too complicated structure, relatively high cost and are easy to be damaged. Moreover, when the lamp is i...

Problems solved by technology

The installation of the signal light needs a bracket. For different models, the installation methods of the lamps are different, so the installation angles of the lamps are also different. If you use the same installation bracket, you need this bracket to have strong adaptability. It can adapt to various installation methods. The existing installation brackets with strong adaptability are too complicated in structure, relatively high in cost, and easy to damage

Moreover, when the lamps are installed on the vehicle body, due to bumpy road conditions, external forces and other reasons, the mounting brackets crack and even the lamps fall off, which seriously affects the quality of the product.
