Being labeled as in accompanying drawing: 1, top bottom-disc, 2, low bottom-disc, 3, fan wing, 4, bolt, 11, fan wing groove, 12, adjustment plate groove, 21, fan wing groove, 22, adjustment plate groove.
Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 3, the utility model embodiment comprises:
A kind of large-scale fan hub, comprise top bottom-disc 1, low bottom-disc 2, fan wing 3 and angle adjustment dish (figure does not look), together with described top bottom-disc 1 is fastened and connected with low bottom-disc 2, on described top bottom-disc 1 and low bottom-disc 2, be provided with multiple corresponding evenly distributed fan wing grooves 11, 21 and adjustment plate groove 12, 22, described adjustment plate groove 12, 22 are positioned at fan wing groove 11, 21 inner side, described angle adjustment dish is separately positioned on the end of fan wing 3, described fan wing 3 and angle adjustment dish are all arranged on the fan wing groove 11 between top bottom-disc 1 and low bottom-disc 2, 21 and adjustment plate groove 12, in 22, described fan wing 3 protrudes from the periphery of top bottom-disc 1 and low bottom-disc 2, described top bottom-disc 1 is fixedly connected with by 18 bolts 4 with low bottom-disc 2.
In above-mentioned; 18 described bolts 4 are divided into 6 groups; every group of 3 bolts, 4 triangularity structures; by bolt 4, top bottom-disc 1 and low bottom-disc 2 are very fastened and connected; in the middle of top bottom-disc 1 and low bottom-disc 2 are clamped in fan wing 3 simultaneously, relatively traditional single piece type locking mechanism, can obtain more stable contact and stressing conditions; do not allow fan wing 3 come off by bolt 4, multiple protective fan wing 3 can not lose efficacy and drop out.
Further, on described fan wing 3 and angle adjustment dish, all there is the pin-and-hole (figure does not look) of 3 different angles, assemble by converting different pin-and-hole position, can obtain 3 kinds of different angles, can select according to different special workplaces. For differing heights 6-25 rice, can carry out angle fine setting by end wing, make the air quantity of fan have optimum efficiency to differing heights.
