Description

Technical Field

[0001] The utility model relates to the technical field of fan safety protection, and particularly relates to a safety protection fan grille. Background Art

[0002] Square axial flow cooling and exhaust fans are widely used in various scenarios that require ventilation or cooling due to their convenient installation, stable operation, and low noise. To prevent foreign objects from blocking the air inlet of the square axial flow cooling and exhaust fan, a flat safety protection fan grille 100' that is matched with the square axial flow cooling and exhaust fan has emerged on the market, as shown in Figure 1 . Although this flat safety protection fan grille provides safety protection, if a foreign object leans against it, the air inlet will be blocked by the foreign object, and thus the square axial flow cooling and exhaust fan cannot achieve normal ventilation or cooling effects. Summary of the Utility Model

[0003] To solve the above problems of the prior art, it would be beneficial to provide a safety protection fan grille according to the utility model that can still ensure normal ventilation of the square axial flow cooling and exhaust fan even when foreign objects appear.

[0004] To achieve the above object, according to one aspect of the utility model, there is provided a safety protection fan grille, which includes a front protection ring assembly, a side protection ring, a first protection bracket, and a second protection bracket. Among them, the first protection bracket and the second protection bracket both include a connecting leg and a supporting leg. The front protection ring assembly includes a plurality of concentric protection rings with a distance not greater than 12 mm between each other. The connecting legs are located above the front protection ring assembly and are tangent to and connected with the plurality of concentric protection rings. The side protection ring is located below the front protection ring assembly at an interval not greater than 12 mm and is tangent to and connected with the supporting legs.

[0005] Further, the end of the supporting leg has an installation ring, and the installation ring is located below the side protection ring.

[0006] Still further, the connecting legs of the first protection bracket and the second protection bracket are both L-shaped and have an L-shaped corner. The connecting legs are located above the front protection ring assembly and form a 90° angle with each other, and a supporting leg is correspondingly arranged at the end of each connecting leg.

[0007] Even further, the L-shaped corners are all on the diameter axis of the innermost protection ring of the plurality of concentric protection rings of the front protection ring assembly, and there is a gap between them.

[0008] Also further, the plurality of concentric protection rings of the front protection ring assembly and the side protection ring are all antioxidant, corrosion-resistant, and wear-resistant protection rings.

[0009] Compared with the prior art, in the present utility model, through the above structural arrangement, it can not only ensure the smooth flow of air, but also when a foreign object adheres to the safety protection fan net cover, enable the air to enter from the side of the fan net cover, thereby ensuring normal ventilation and cooling effects, etc., and can conveniently adapt to square axial flow cooling and exhaust fans of different specifications.

[0010] These aspects and other aspects of the present utility model will be more clearly elaborated by referring to the embodiments described below. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The structure of the present utility model and further objects and advantages will be better understood from the following description in conjunction with the drawings, in which the same reference numerals identify the same elements:

[0012] Figure 1 is a schematic side view of the existing safety protection fan net cover;

[0013] Figure 2 is a three-dimensional structure schematic diagram of the safety protection fan net cover according to a specific embodiment of the present utility model;

[0014] Figure 3 is Figure 2 a schematic side view of the safety protection fan net cover shown;

[0015] Figure 4 is Figure 2 a schematic diagram of the application state of the safety protection fan net cover shown. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will describe the specific embodiments of the present utility model in conjunction with the drawings.

[0017] As Figures 2 to 3 shown, the safety protection fan net cover 100 according to a specific embodiment of the present utility model includes a front protection ring assembly 1, a side protection ring 3, a first protection bracket 5 and a second protection bracket 7. Among them, the first protection bracket 5 includes a connecting leg 50 and a supporting leg 52, and the second protection bracket 7 includes a connecting leg 70 and a supporting leg 72. The front protection ring assembly 1 includes a plurality of concentric protection rings 10 with a distance between each other not greater than 12 mm. The connecting legs 50 and 70 are located above the front protection ring assembly 1 and are tangent to and connected to the plurality of concentric protection rings 10. The side protection ring 3 is located below the front protection ring assembly 1 at an interval not greater than 12 mm and is tangent to and connected to the supporting legs 52 and 72. As Figure 2 shown, the end of the supporting leg 52 has an installation ring 520, and the end of the supporting leg 72 has an installation ring 720, and these installation rings are located below the side protection ring 3.

[0018] As Figure 2As clearly shown, in this embodiment, the connecting leg 50 of the first protective bracket 5 is L-shaped and has an L-shaped corner 51, and the connecting leg 70 of the second protective bracket 7 is also L-shaped and has an L-shaped corner 71.
