The technical scheme that the utility model adopts is: a kind ofly with function of shielding, just tear air ducting open, comprise top board and be located at respectively the biside plate of top board opposite edges, it is characterized in that being symmetrically arranged with flange on biside plate, a side in the bottom of biside plate is provided with grab, is provided with the first location hole on biside plate.
By technique scheme, the opposite side in the bottom of biside plate is provided with keeper, is provided with the second location hole on keeper.
By technique scheme, on described the first bending member, or/and be at least provided with a Wire channel in building on biside plate, by offering Wire channel in building, wire is drawn from the inner side of the first bending member.
By technique scheme, on top board, be provided with the second bending member.
By technique scheme, the length of described the second bending member is less than the length of top board, at the two ends of the second bending member, forms lead end.
By technique scheme, on the second bending member, on the end face parallel with top board, be provided with fixing hole.
The obtained beneficial effect of the utility model is: 1, by this air ducting by flange, undertaken spacingly, prevent assembling excessively; The first location hole and grab be for fixing air ducting, make this air ducting installation steps simple, be convenient to dismantle, improved operating efficiency; And the usage quantity of having saved screw, provides cost savings; 2,, by the first bending member and the second bending member and Wire channel in building are set, make on the one hand strong, weak electricity from different path wiring and isolation, to reach the jamproof effect of shielding; On the other hand, contribute to strengthen the intensity of air ducting, prevent that this device from deforming.
