Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-4, a dust keeper for construction, including the sky curtain system 1, the both ends of sky curtain system 1 set up mounting bracket 2, and the inside of mounting bracket 2 is provided with the equipment that pulls the sky curtain and remove for make the sky curtain open or close, the surface mounting of mounting bracket 2 has support frame 3, and support frame 3 installs on the building equipment, the surface fixed mounting of support frame 3 has drive assembly for make mounting bracket 2 rotate, thereby slope sky curtain system 1, the surface fixed mounting of support frame 3 has backup pad 4, the surface movable mounting of support frame 3 has expansion plate 5, expansion plate 5 and backup pad 4 are located the below of mounting bracket 2, and are located mounting bracket 2 symmetry position for the support to mounting bracket 2, the surface mounting of support frame 3 has the removal subassembly for make expansion plate 5 remove.
During initial state, mounting bracket 2 is in the horizontally state, the sky curtain system 1 of this moment also is in the horizontally state, the effect of dust fall has, after the sky curtain system 1 uses a period, a certain amount of fallen leaves and mud ash can be piled up to its top, telescopic plate 5 moves away from mounting bracket 2 this moment, make mounting bracket 2 rotate through drive assembly, sky curtain system 1 will be in the state of slope, fallen leaves or mud ash of its upper surface just can fall, guarantee that sky curtain system 1 can continue to use, when handling finishes, drive assembly makes mounting bracket 2 get back to initial position, telescopic plate 5 moves to the below of mounting bracket 2 again, support mounting bracket 2.
