Description

High-mounting-stability glass lens of automotive headlamp Technical Field The utility model relates to the field of glass lenses, in particular to an automobile headlamp glass lens with high installation stability. Background The automobile headlight is also called as headlight, is a core lighting device for vehicles to run at night, and generally consists of a mounting seat, a bulb, a reflector and a glass lens. The glass lens is an aspheric convex lens generally, and can collect light rays emitted by the bulb, so that the light can illuminate the front better. When the glass lens is installed, the glass lens needs to be pressed into the front end of the installation seat, the annular clamping jaw on the installation seat clamps the glass lens, when the glass lens is round, the edge of the glass lens is round, the glass lens is difficult to ensure that the glass lens cannot rotate in the using process of a vehicle only by the pressure of the clamping jaw, and the condensing effect of the aspherical convex lens-shaped glass lens can be changed after the glass lens rotates, so that the lamp light shape and the lighting effect are achieved. Therefore, the conventional round glass lens has a problem of poor mounting stability. Disclosure of utility model The utility model aims to provide an automobile headlamp glass lens with high installation stability. The utility model has the advantage of higher installation stability. The technical scheme includes that the glass lens of the automobile headlamp with high mounting stability comprises a mounting seat and a circular convex lens-shaped lens main body, wherein a lens hole is formed in the front end of the mounting seat, a plurality of annular uniformly distributed positioning protrusions are arranged in the lens hole, a horizontally inwardly extending mounting ring is arranged on the lens hole, a plurality of annular uniformly distributed mounting holes are formed in the mounting ring, a side edge extending horizontally outwards is arranged on the edge of the lens main body, a positioning notch is formed in the position, corresponding to each positioning protrusion, of the side edge, a positioning hole is formed in the position, corresponding to each mounting hole, of the side edge, a plastic expansion pipe is clamped in the positioning hole in a matched mode, and a screw with the end portion clamped outside the mounting hole is connected in the plastic expansion pipe in a threaded mode. In the automotive headlamp glass lens with high installation stability, the outer side surface of the side edge and one side surface protruding towards the lens main body are frosted. In the automotive headlamp glass lens with high installation stability, the positioning hole is frosted. In the automotive headlamp glass lens with high mounting stability, the thickness of the side edge is 5-8 mm, and the thickness of the mounting ring is 10-15 mm. Compared with the prior art, the lens main body is positioned in the mounting seat and is not easy to rotate relative to the mounting seat by arranging the annular mounting ring which horizontally extends inwards at the lens hole at the front end of the mounting seat and arranging the annular side edge which horizontally extends outwards at the edge of the circular convex lens main body, wherein the side edge can be matched and clamped at the rear side of the mounting ring and matched with the positioning notch and the positioning bulge, and then the lens main body can be stably fixed on the mounting seat by screwing the plastic expansion pipe in the positioning hole after passing through the mounting hole through the screw. In addition, the outer side surface of the side edge and the side surface protruding towards the lens main body are frosted, so that the friction force between the lens main body and the mounting seat is large, and the mounting stability of the lens main body is further improved. Through setting up location Kong Namo sand, improve the frictional force between locating hole and the plastics expansion pipe, when making the screw in the plastics expansion pipe, the plastics expansion pipe is difficult for relative locating hole rotation. The thickness of side is 5~8mm, and the thickness of collar is 10~15mm, and structural strength is good, and the durability is better. Therefore, the utility model not only can improve the installation stability, but also has the advantages of more convenient installation and operation and better durability.
