Through setting up apron 112 for apron 112 is in the open condition, and the installation of being convenient for or dismantle projector 2, when apron 112 is in the closed condition, shelters from the opening 1113 of installation cavity 114, makes the inside airtight space that forms of case body 111, prevents external dust or steam entering case body 111 in, avoids the inside deposition that appears of projector 2.
According to an embodiment of the present utility model, the case body 111 is further provided with a latch 113, and the latch 113 is used for locking the cover plate 112 in a closed state, so as to prevent the cover plate 112 from being automatically opened under the action of gravity when the cover plate is downward arranged. According to another embodiment of the present utility model, a tension spring may be disposed in the case body 111, one end of the tension spring is connected to the case body 111, the other end of the tension spring is connected to the cover plate 112, and the tension spring is used for pulling the cover plate 112 to close.
The foregoing is only the preferred embodiments of the present utility model, and not the limitation of the scope of the present utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the present utility model.
