Description

Lens assembly structure

Technical Field

The present utility model relates to a lens assembly structure.

Background

The lens is an optical element made of transparent substances and the surface of the lens is a part of spherical surface; the reflecting cup is a reflector which uses a point light source bulb as a light source and needs long-distance spotlight illumination, and is usually a cup type commonly known as a reflecting cup. In order to achieve better optical effect, many existing lamps are provided with lenses and reflecting cups. The prior lens and the prior reflective cup are generally provided with a buckle on the reflective cup, and then the buckle is used for hooking the lens so as to realize the connection between the lens and the reflective cup. However, the reflective cup with the structure is easy to deform the buckle excessively, so that the lens is loose or the buckle is broken.

As shown in fig. 7 and 8, when the conventional lens body 20 is mounted in the lens holder 10, it is positioned and engaged with the annular boss 120 of the lens holder 10 by the limiting boss 210 of the lens body 20, and is fixed to the upper end surface of the limiting boss 210 by the snap 110. In this structure, when the lens body 20 is mounted, the lens body moves from top to bottom, and the limiting boss 210 presses the buckle 110 to deform and then the lens body is fixed between the buckle 110 and the annular boss 120. In the disassembly process, the plurality of buckles 110 need to be separated outwards by external force to take out the lens body 20 from bottom to top. This type of detachment is inconvenient to detach and breaking the buckle 110 by external force easily causes the buckle 110 to break.

In addition, the limit boss 210 is simply engaged with the annular boss 120 by the snap 110 to limit the limit boss up and down, and in this fixing manner, the lens body 20 may rotate relative to the lens holder 10, and does not have a rotation limiting structure.
