Detailed Description

In order to more clearly describe the technical contents of the present invention, the following further description is given in conjunction with specific embodiments.

As shown in fig. 1-3, for the utility model discloses an embodiment of aluminium base board module, wherein, including lens 1, aluminium base board 2 and insulating piece 3, the edge of lens 1 set up two pairs of first connecting piece 4, insulating piece 3 in the position that corresponds first connecting piece 4 set up two pairs of second connecting pieces 5, first connecting piece 4 and second connecting piece 5 cooperate, just aluminium base board 2's width set to be less than insulating piece 3's width, make aluminium base board 2 fix lens 1 and insulating piece 3 between.

The insulating sheet can be made of high-temperature-resistant fireproof material. The first connecting piece and the second connecting piece can modify the structure fixing mode according to the type of the adapted lens structure, are not limited to the type, size and position of the through hole, and can design the adapted structure fixing mode along with the adapted lens structure, so that the insulating sheet, the aluminum substrate and the lens are assembled into a whole.

As shown in fig. 1 to 3, the first connecting member 4 is a buckle, the second connecting member 5 is a first through hole, and the buckle is matched with the first through hole. The catch and the first through hole may be arranged to have a square profile. In order to facilitate the stability of the snap fit, the end of the first connector is provided with a hook-like structure, so that the connection between the lens 1 and the insulating sheet 3 is more stable.

As shown in fig. 1 and 3, a third connecting member 7 is disposed at the edge of the lens 1, the third connecting member 7 is disposed corresponding to the first connecting member 4, a fourth connecting member 6 is disposed at a position corresponding to the third connecting member in the insulating sheet 3, and the third connecting member 7 is matched with the fourth connecting member 6.
