Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 4, a projector for multimedia teaching comprises a projector housing 1, a heat sink 3 is mounted on an outer surface of one side of the projector housing 1, a heat sink window 2 is mounted on an outer surface of one side of the heat sink 3, clamping pieces 6 are mounted on inner surfaces of the periphery of the projector housing 1, a main board 5 is mounted inside the heat sink 3, a rubber column 7 is mounted on an outer surface of an upper end of the projector housing 1, and a threaded opening 4 is mounted on an outer surface of an upper end of the heat sink 3.

Further, the heat dissipation window 2 and the heat dissipation groove 3 are fixedly installed, and the heat dissipation groove 3 is connected with the projector shell 1 in a sliding mode.

Furthermore, the clamping pieces 6 are fixedly installed with the projector shell 1, the inner surface of the projector shell 1 is detachably installed with the outer surface of the main board 5 through the inner surface of the clamping pieces 6, and the clamping pieces 6 are four groups and are uniformly distributed on the inner surface of the periphery of the projector shell 1.

Further, rubber column 7 and projector shell 1 are threaded connection, and screw thread mouth 4 is located the upper end middle part of radiating groove 3, and the lower extreme surface of rubber column 7 runs through projector shell 1 and screw thread mouth 4 and supports the upper end surface of tight mainboard 5.
