Abstract

The invention discloses a ventilating opening cover of a factory building. The ventilating opening cover comprises a ventilating opening connector, a first telescopic layer is arranged on the ventilating opening connector, a second telescopic layer is arranged on the first telescopic layer, a cover body is arranged at the top of the second telescopic layer in an opening and closing mode, a ventilating grill is arranged between the cover body and the ventilating opening connector, and the ventilating grill is made of metal sheets and is detachable. As the multiple telescopic layers are arranged on the ventilating opening cover body, and the ventilating grill capable of changing along with the telescopic layers is arranged on the side face, the ventilating function is effectively achieved without exposing a ventilating opening, and the normal operation of a ventilating pipeline is greatly guaranteed.

Description

technical field [0001] The invention relates to a ventilation hole cover, more precisely, a factory building ventilation hole cover. Background technique [0002] In order to maintain the internal air environment of the factory building, a central air-conditioning system needs to be installed inside to maintain the air quality in the factory building. However, the commonly used air vents are exposed openings, which will affect the normal operation of the system due to the entry of foreign matter. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a factory building vent cover that prevents external foreign matter from entering the pipeline. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A vent cover of a factory building, comprising a vent connection body, a first telescopic layer is arranged on the vent con...
