Abstract
The invention relates to a cracking-prevention structure suited on a lens, which consists of the lens (1) and an injection-molding lens (2), wherein the lens (1) is provided with a flange (3), the injection-molding lens (2) is provided with a rove, the flange (3) of the lens (1) is clamped into the groove of the injection-molding lens (2); the cracking-prevention structure is characterized in that: the flange (3) of the lens (1) is a reinforcing rib. In the invention, the contact area of the two lenses can be directly increased, the stressed force in a unit area is reduced, the air tightness of a lamp is effectively improved, the cracking is prevented, and the yield of the products is improved to 93.7% from 75.2 percent.
