Description

Packing box of retroversion formula centrifugal fan

Technical Field

The utility model belongs to the technical field of centrifugal fans, and particularly relates to a packaging box of a backward-inclined centrifugal fan.

Background

The centrifugal fan is widely applied to industries such as ventilation and refrigeration, when the centrifugal fan works, the motor drives the wind wheel to rotate at a high speed, a large centrifugal force can be generated, the application product has a high requirement on the dynamic balance of the fan, and if the dynamic balance does not reach the standard, the fan can generate a large vibration to damage the fan and even other related equipment. The balance and the appearance of the fan can be damaged at great risk in transportation, for example, the wind wheel can be damaged in transportation due to vibration caused by vehicle shaking, turning caused by bumping of the road surface, and pressure caused by fan inertia deviation and fan stacking caused by speed change.

The utility model relates to a novel packaging wooden box of an outer rotor axial flow fan, which belongs to the prior art, such as the patent with the patent number of 2011101364374, and provides a fan packaging wooden box, wherein the fan packaging wooden box uses the structures of an upper foam block, a lower foam block and a foam bottom plate to position and install mounting ribs of the fan, and the positioning and mounting structure is not suitable for a back-tilting centrifugal fan.

The backward inclined centrifugal fan comprises a current collector, a motor and a wind wheel, wherein the motor is connected with the wind wheel and drives the wind wheel to rotate, the current collector and the wind wheel are coaxially arranged and can guide outside air into the wind wheel, and the wind wheel of the backward inclined centrifugal fan comprises an upper chassis, a lower chassis and a plurality of blades arranged between the upper chassis and the lower chassis.

The motor, the wind wheel and the current collector (wind guide ring) cannot be fixed well by the packaging wooden box, so that collision is easily generated among parts in the transportation process, and each part can also collide with the packaging box body; meanwhile, the maximum diameters of the upper chassis and the lower chassis of the wind wheel are the same, and the inner end of the upper chassis is bent upwards, so that the upper chassis and the lower chassis cannot be fixed by using a foam block; further, because this packing wooden case supports through outermost wooden box, the great but structural strength of weight of wooden box is limited, and it is limited to cause the quantity that the box can pile up, if the quantity of stacking is too much, causes the box to warp easily to lead to the fan in the box to be crushed, cause the damage of fan.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model aims to provide a packing box which can adapt to a backward tilting type centrifugal fan.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a hypsokinesis formula centrifugal fan's packing box, includes upper end open-ended box and can be with box confined lid, its characterized in that: the utility model discloses a set up the box, including box, the box is equipped with the lower picture peg that can enclose into lower holding chamber and can enclose into the last picture peg in holding chamber, the lower terminal surface of lower picture peg supports with the bottom of box and leans on, the up end of going up the picture peg supports with the lower terminal surface of lid and leans on, go up the picture peg and be equipped with between the picture peg down with both vertically hanger plate, the holding intracavity can be arranged in to centrifugal fan's wind wheel upside down, the lower chassis fixed connection of motor and wind wheel, the motor can pass through fastener and hanger plate fixed connection, there is the clearance between the bottom of the case of box and the wind wheel of fixing on the hanger plate, centrifugal fan's collector is placed in the up end of hanger plate and is located the holding intracavity, the height that highly more than or equal to the collector of going up the picture peg.

Because the wind wheel structure of the backward inclined centrifugal fan is special, it is difficult to directly fix the wind wheel structure in the packing box; the wind wheel is fixedly connected with the motor, and then the hanging plate is arranged in the box body and used for fixing the motor, so that the wind wheel is suspended in the air, external vibration and impact can be perfectly isolated, the impact and pressure in any direction cannot damage the balance of the fan within the range that the packing box can bear the impact and the pressure, and the appearance is kept intact; the design of the upper inserting plate and the lower inserting plate not only limits the position of the hanging plate in the vertical direction, but also can enhance the structural strength of the whole packaging box, and is equivalent to two layers of box bodies.
