Novel fan net cover

Abstract

The invention relates to a novel fan net cover. The novel fan net cover comprises a first net cover and a second net cover, wherein a connecting opening is arranged on the rear side of the first net cover, the second net cover is detachably arranged on the rear side of the first net cover and connected with the connecting opening, the diameter of the first net cover is big, the diameter of the second net cover is small, the diameter of the connecting opening is smaller than the maximum diameter of the first net cover, and the connecting opening is located on the rear side of the maximum diameter position of the first net cover. The first net cover with the big diameter and the second net cover with the small diameter are adopted for the novel fan net cover, the second net cover is detachably connected with connecting opening on the rear side of the first net cover, the first net cover is connected with the second net cover through bolts, buckles are saved, and thus the problems caused by the fact that a front net cover and a rear net cover of an existing fan net cover are connected by adopting buckles or bolts or annular hoop straps are avoided; meanwhile, cost is also saved, and the production difficulty and the transportation difficulty are lowered. Therefore, the novel fan net cover is convenient to disassemble and assemble, low in production cost and easy to produce.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a novel fan guard.

Problems solved by technology

However, the above-mentioned connection methods all have shortcomings: (1) The front grille and the rear grille adopt the locking method of bolts combined with annular hoops. It first needs to align and close the outer ring strips of the front and rear grilles , the ring band wraps the outer ring strips of the front and rear grilles, and the ring straps tighten the front and rear grilles together, and then lock the opening of the ring straps with bolts, thereby locking the front and rear grilles Tight together, but this locking method is troublesome to disassemble and assemble, difficult to operate, cumbersome, and inconvenient to operate

(2) Compared with the ring band, the front and rear nets are locked by buckles, which is easy and simple to operate and convenient to disassemble. The existing front and rear nets of fans are locked together by multiple buckles. Existing buckles are divided into fixed and detachable. Both the fixed and detachable buckles have U-shaped openings. The frame of the fixed buckle is locked together by the U-shaped opening of the fixed buckle, so as to lock the front and rear grilles together, but one end of the existing fixed buckle is riveted on the fr
