Description
Technical field
The utility model relates to Fan Equipment field, especially a kind of safety check of small-sized axial flow fan.
Background technique
Now on the market, the kind of blower fan is multifarious.For the axial-flow blower (blower fan market price is about 100 yuan) that a diameter is 300MM, if will fill a safety check, that price is offer 40 yuan also, and people can not accept, and does not have the manufacturer of the safety check of blower fan.For axial-flow blower, safety check can play insect protected mouse, dust-proof sand, rainwater-proof, the sealing process of anti-air-return.The structure of the safety check of blower fan, traditional is all louvered, several pieces blinds are through on an annular iron ring, waste time and energy, and when blower fan operate time due to blinds with iron ring be all irony, the vibration of blower fan can make blinds vibrate to make a noise, and the structure of louvered can only be contained in exhaust outlet, for the situation that axial-flow blower puts into ventilation duct just can not being filled the safety check of louvered.The utility model is solve conventional axial flow blower fan safety check complex manufacturing technology, and practicality can produce noise and the limited drawback of real-world environment.
Model utility content
The purpose of this utility model is the safety check providing a kind of small-sized axial flow fan, by the improvement to safety check, save material, reduce noise, add that other parts reach insect protected mouse with the use of making it, dust-proof sand, rainwater-proof, the effect of anti-air-return, applicable different installation environment, improve working life, and structure is simple, easy to use.
In order to achieve the above object, the technical solution of the utility model is:
A kind of safety check of small-sized axial flow fan, comprise Stainless Steel Wire axis, described Stainless Steel Wire axis is provided with main semicircle galvanized sheet iron flap, secondary semicircle galvanized sheet iron flap, described main semicircle galvanized sheet iron flap, secondary semicircle galvanized sheet iron flap are provided with connecting body, described connecting body offers the attachment hole be socketed on Stainless Steel Wire axis, described connecting body, main semicircle galvanized sheet iron flap, secondary semicircle galvanized sheet iron flap is integrally manufactured forms; Described Stainless Steel Wire axis is provided with torsion spring, described torsion spring is provided with two supporting legs of band bent angle, described torsion spring and supporting leg is integrally manufactured forms; Described Stainless Steel Wire axis two ends are provided with plasticity anchor post, described plasticity anchor post offer the attachment hole of connecting fan.
Described main semicircle galvanized sheet iron flap, secondary semicircle galvanized sheet iron flap offer groove.
The beneficial effects of the utility model are: the safety check of a kind of small-sized axial flow fan of the present utility model, by be arranged on two semicircular galvanized sheet iron flap and torsion spring etc. on Stainless Steel Wire axis with the use of, both saved material, reduced again noise, it is made to reach insect protected mouse, dust-proof sand, rainwater-proof, the sealing process of anti-air-return, applicable different installation environment, improve working life, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of main semicircle galvanized sheet iron flap in the utility model;
Fig. 3 is the structural representation of secondary semicircle galvanized sheet iron flap in the utility model.
Embodiment
Embodiment 1
The safety check of a kind of small-sized axial flow fan as Figure 1-3, comprise Stainless Steel Wire axis 1, described Stainless Steel Wire axis 1 is provided with main semicircle galvanized sheet iron flap 2, secondary semicircle galvanized sheet iron flap 3, described main semicircle galvanized sheet iron flap 2, secondary semicircle galvanized sheet iron flap 3 are provided with connecting body 4, described connecting body 4 offers the attachment hole 5 be socketed on Stainless Steel Wire axis 1, described connecting body 4, main semicircle galvanized sheet iron flap 2, secondary semicircle galvanized sheet iron flap 3 is integrally manufactured forms; Described Stainless Steel Wire axis 1 is provided with torsion spring 6, described torsion spring 6 is provided with two supporting legs 7 of band bent angle, described torsion spring 6 forms with supporting leg 7 is integrally manufactured; Described Stainless Steel Wire axis 1 two ends are provided with plasticity anchor post 8, described plasticity anchor post 8 offer the attachment hole 9 of connecting fan.
Described main semicircle galvanized sheet iron flap 2, secondary semicircle galvanized sheet iron flap 3 offer groove 10.
During blower fan running, the elastic force that the thrust due to wind is greater than torsion spring makes two semicircular galvanized sheet iron flap be blown open, because the elastic force two semicircular galvanized sheet iron flap of torsion spring just in time synthesizes circle when blower fan stops.
The safety check of a kind of small-sized axial flow fan of the present embodiment, by be arranged on two semicircular galvanized sheet iron flap and torsion spring etc. on Stainless Steel Wire axis with the use of, both saved material, reduced again noise, it is made to reach insect protected mouse, dust-proof sand, rainwater-proof, the sealing process of anti-air-return, applicable different installation environment, improve working life, and structure is simple, easy to use.
