In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
a fresh air cabinet structure facilitating fan maintenance comprises a cabinet body, wherein a square fan maintenance opening is formed in a cabinet side plate 1 corresponding to a position of a fan in a cabinet, a right-angle folded edge 11 which is bent towards 90 degrees in the cabinet is formed in the cabinet side plate on one side of the fan maintenance opening, and an inwards concave supporting folded edge 12 is formed in the cabinet side plate on the other three sides of the fan maintenance opening; the fan access hole is provided with a door panel 2, one side of the door panel is provided with a J-shaped hook groove 21, the J-shaped hook groove 21 is hooked on the right-angle folded edge 11 of the case side plate, and the edge parts of the other three sides of the door panel are covered on the concave supporting folded edge 12 of the case side plate and are fixed through bolts.
The depth of the inward concave supporting folded edge 12 on the case side plate towards the inside of the case corresponds to the thickness of the door plate 2, and the door plate 2 is flush with the surface of the case side plate 1 when covering the fan access hole.
Under the proposal that the square fan access hole is arranged on the side plate of the case corresponding to the position of the fan in the case, the technical personnel in the field can make other various alternative schemes for the connection mode between the fan access hole and the door plate by combining the prior art, which is not listed herein.
According to the fresh air case structure convenient for fan maintenance, the square fan maintenance opening is formed in the case side plate corresponding to the position of the fan in the case, so that the whole fan can be taken out for replacement or maintenance, and the defect that the fan is inconvenient to maintain and replace due to the existing case design is overcome.
The chassis side plate on one side of the fan access hole is provided with a right-angle folded edge 11 which is bent towards 90 degrees in the chassis, and the other chassis side plates on the three sides of the fan access hole are provided with concave supporting folded edges 12; one side of the door panel 2 is provided with a J-shaped hook groove 21, the J-shaped hook groove 21 is hooked and sleeved on the right-angle folded edge 11 of the case side plate to realize the quick connection between the two, and the edge parts of the other three sides of the door panel are covered on the concave supporting folded edge 12 of the case side plate and are fixedly connected through bolts. The depth of the inward concave supporting folded edge 12 on the case side plate towards the inside of the case corresponds to the thickness of the door plate 2, and the door plate 2 is flush with the surface of the case side plate 1 when covering the fan access hole. Above-mentioned fan access hole and door plant structure have guaranteed the leakproofness of quick-witted case promptly, do not destroy the aesthetic property of quick-witted case curb plate again, and door plant easy dismounting on the fan access hole has reduced the work load when engineering installation and maintenance.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
