A kind of fan blade structure with good opening and closing performance, comprise blade, described blade upper portion is in sticking up arcuate structure outward, lower portion is indent arcuate structure, this is outer sticks up arcuate structure and indent arcuate structure makes the upper and lower two side portions of blade all form curved surface, it is described that outer to stick up arcuate structure corresponding with indent arcuate structure, when making polylith blade combinationally use, in being adjacent to state when adjacent blade closes.
The V-shaped structure of position on the upper side of above-mentioned blade profile, v-shaped structure makes blade to be formed a groove.
Above-mentioned blade is by glass fibre reinforced plastic material injection-compression molding.
It is plane that above-mentioned blade sticks up position between the curved surface of arcuate structure and the groove of v-shaped structure outside.
Above-mentioned blade position between the curved surface and the groove of v-shaped structure of indent arcuate structure is plane.
The two ends of above-mentioned blade are respectively equipped with rotatingshaft.
Above-mentioned rotatingshaft is fixed on the groove end positions of blade, is fixed on blade by the briquetting of a band curve bath.
The thickness of above-mentioned blade is 2-6mm.
The beneficial effects of the utility model:
1, blade upper portion of the present utility model is in sticking up arcuate structure outward, lower portion is indent arcuate structure, this is outer sticks up arcuate structure and indent arcuate structure makes the upper and lower two side portions of blade all form curved surface, it is described that outer to stick up arcuate structure corresponding with indent arcuate structure, when making polylith blade combinationally use, in being adjacent to state when adjacent blade closes.Thus, the utility model has good closed performance, and when using, utilizes the curved surface of top and the bottom to realize balance and open blade, form good guide performance, therefore effectively provide the usability of blade.
2, v-shaped structure of the present utility model forms a groove at blade, this groove, sticks up arcuate structure and indent arcuate structure can improve the rigid of blade integral structure effectively outward, reduces noise, improves blade usability.
3, the utility model is by glass fibre reinforced plastic material injection-compression molding.Make simple, effectively enhance productivity, reduce fabricating cost, and the blade acid-fast alkali-proof that glass fibre reinforced plastic material makes is strong, can extend the working life of blade widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use of the present utility model (closing) phase diagram.
Fig. 3 is use of the present utility model (opening) phase diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Have a fan blade structure for good opening and closing performance as shown in Figure 1 to Figure 3, comprise blade 1, this blade 1 is by glass fibre reinforced plastic material injection-compression molding, and the thickness of blade 1 is 2mm, 3mm, 4mm, 5mm or 6mm, and this thickness is selected according to the size of blower fan.Described blade 1 upper portion is in sticking up arcuate structure 12 outward, lower portion is indent arcuate structure 13, this is outer sticks up arcuate structure 12 and indent arcuate structure 13 makes blade about 1 two side portions all form curved surface 2, it is described that outer to stick up arcuate structure 12 corresponding with indent arcuate structure 13, when polylith blade 1 is combinationally used, in being adjacent to state when adjacent blade 1 closes, concrete, described outer stick up arcuate structure 12 outer to stick up arc shape corresponding with the imploded arcs size of indent arcuate structure 13, when blade closes, on the upside of sticking up arcuate structure 12 and lower blade 1-2 outside on the downside of the upper blade 1-1 of polylith blade 1, fit in indent arcuate structure 13 position, form closed state closely.
Further, the V-shaped structure 11 of position on the upper side in described blade 1 cross section, v-shaped structure 11 makes blade 1 to be formed a groove 111.This v-shaped structure 11 and the stiffening rib sticking up arcuate structure 12 outward, indent arcuate structure 13 can form blade, simultaneously, be respectively equipped with rotatingshaft 3 at the two ends of blade 1, this rotatingshaft 3 is fixed on groove 111 end positions of blade 1, is fixed on blade 1 by the briquetting 5 of a band curve bath 4.
It is plane that described blade 1 sticks up position between the curved surface 2 of arcuate structure 12 and the groove 111 of v-shaped structure 11 outside, as shown in Fig. 1 midplane A.Described blade 1 position between the curved surface 2 and the groove 111 of v-shaped structure 11 of indent arcuate structure 13 is plane, as shown in Fig. 1 midplane B.
When the utility model uses, polylith blade is from top to bottom arranged on flow blower casing 6, the side plate 61 of shell 6 both sides is respectively equipped with the fixed edge 7 corresponding with blade profile shape size, the rotatingshaft 3 of this blade 1 is arranged on the relevant position of side plate fixed edge 7, blade 1 is formed on side plate 61 both sides fixed edge 7 and dehisces or closed performance.
When blade 1 closes, as shown in Figure 2, all blades 1 are fitted with fixed edge 7 by deadweight is sagging, by stick up arcuate structure 12 outward outer to stick up arc shape corresponding with the imploded arcs shape size of indent arcuate structure 13, on the upside of sticking up arcuate structure 12 and lower blade 1-2 outside on the downside of the upper blade 1-1 of polylith blade 1, fit in indent arcuate structure 13 position, forms closed state closely.
When blade 1 is opened, as shown in Figure 3, rotated by rotatingshaft 3, all blades 1 are opened, and the lower outside stress surface sticking up the curved surface formation wind that arcuate structure 12 is formed of each blade 1, when fan starting is blown, automatically the Surface forming equilibrium surface with indent arcuate structure 13 on blade 1 is opened by the curved surface by wind of sticking up arcuate structure 12 outward, make blade 1 when air-supply is opened, blade 1 obtains stable equilibrium, and wind is better discharged.
