Problems solved by technology

[0002] Ventilation fans are essential equipment in every factory and workshop. Ventilation fan covers are external devices that protect the ventilation fans. The traditional ventilation fan covers are simple metal frame structures that can only protect the ventilation fan blades from being disturbed by objects. The traditional ventilation fan covers are mostly fixed by The screws are tight, making it difficult to disassemble when servicing is required after long periods of use

Embodiment 1

[0012] Provide a new type of high-durability exhaust fan cover, including: cover bearing point 1, cover support rib 2, cover inner ring 3, cover outer ring 4, gauze 5, louver plate 6, fixing screw 7, backing plate 8, mounting frame 9 1. Screw protection block 10, outer cover bearing point 1 is set on the outer cover support rib 2, gauze 5 is installed around the outer cover bearing point 1, outer cover inner ring 3 is installed on the outer cover support rib 2, louver plate 6 is installed on the outer side of outer cover inner ring 3, inside the outer cover Ring 3 one side is installed outer cover outer ring 4, and outer cover outer ring 4 side is installed mounting frame 9, and fixing screw 7 is installed on the mounting frame 9, screw guard block 10 is installed on the fixing screw 7, backing plate 8 is installed at the bottom of fixing screw 7.

Embodiment 2

[0014] The louver 6 can prevent the exhaust fan from flowing backwards, causing external dust and gravel to enter the exhaust fan, causing the inside of the fan to age, and the dust and sand are very difficult to clean; when it is not in use, the outside air can enter the exhaust fan through the gauze 5 for a small amount of air flow Circulation, the gauze 5 can effectively prevent too much gravel from entering the exhaust fan; after the fixing screw 7 is tightened, the backing plate 8 is closely connected with the exhaust duct, which is very firm and easy to disassemble during maintenance; the screw guard 10 can effectively protect the fixing screw 7. Avoid the fixing screw 7 being exposed to the air for a long time to age and rust, which will cause the fixing screw 7 to become loose or unable to be disassembled.

Abstract

The utility model relates to a novel high-durability exhaust fan cover which comprises a cover bearing point, a cover supporting rib, and the like. The novel high-durability exhaust fan cover is characterized by further comprising a gauze, a louver, a fastening screw, a base plate, a mounting bracket, and a screw guard block. The cover bearing point is set on the cover supporting rib, the gauze isarranged around the cover bearing point, a cover inner ring is mounted on the cover supporting rib, the louver is arranged on the outer side of the cover inner ring, one side of the cover inner ringis provided with a cover outer ring, and the mounting bracket is arranged on one side of the cover outer ring. The louver of the novel high-durability exhaust fan cover can prevent exhaust fan air from flowing backwards; when the use of the novel high-durability exhaust fan cover is stopped, outside air can enter the exhaust fan through the gauze to carry out a small amount of airflow circulation,and the gauze can effectively prevent that excessive gravel enters the exhaust fan; after the fastening screw is tightened, the base plate is tightly connected with an exhaust air duct very firmly, and the disassembly is easy during maintenance; the screw guard block can effectively protect the fastening screw and prevent the fastening screw from becoming loose or unable to be disassembled.

Description

technical field [0001] The invention relates to an exhaust equipment accessory, in particular to a novel high-durability exhaust fan cover. Background technique [0002] Ventilation fans are essential equipment in every factory and workshop. Ventilation fan covers are external devices that protect the ventilation fans. The traditional ventilation fan covers are simple metal frame structures that can only protect the ventilation fan blades from being disturbed by objects. The traditional ventilation fan covers are mostly fixed by The screws are tight, making it difficult to remove when servicing is required after long periods of use. Contents of the invention [0003] According to the above technical problems, the present invention provides a new type of high-durability exhaust fan cover, including: the bearing point of the cover, the supporting ribs of the cover, the inner ring of the cover, and the outer ring of the cover, and its features also include: gauze, louvers, fi...
