Abstract

The utility model relates to the structural improvement of a power-free air interchanging device. The utility model comprises a supporting seat, and a revolving body which is composed of blades is arranged above the supporting seat. The utility model has the essential structure that the bottom end of a shaft is fixed on the supporting seat, and a bearing on the top end of the shaft is fixed on a base with external threads by a top cover of the revolving body. The utility model is convenient to disassemble and has the characteristic of hard influence by external wind.

Description

Unpowered air interchanger

The utility model relates to the improvement of unpowered air interchanger structure.

The last end structure of existing unpowered air interchanger: a plurality of air blades are arranged on around the circular slab, and last cap is arranged on the upper end of fixed axis, for rigid bearing is riveted a flat board under round;

The structure of revolving body: air blade upper end be fixed on circular slab around, the lower end is fixed on the outside portion of revolution frame, the inboard is provided with the axis hole that runs through gyroaxis.

The assembling of this product is the upper and lower plate of riveted joint, carries out the riveted joint of the top and bottom of air blade thereafter.Therefore, increased staking process three times, it is slow assembling speed to have occurred, not easy-to-dismount problem.

In addition, revolving body mainly is the lower end rotation by gyroaxis, but owing to be subjected to irregular windage, causes that easily revolving body rocks, and has caused the wearing and tearing of gyroaxis and the generation of fault.

The purpose of this utility model just provides a kind of unpowered air interchanger that is easy to dismounting, can be subjected to extraneous windage.

The purpose of this utility model is achieved in that the utility model comprises bearing, the revolving body that the bearing top is made up of fan blade, its structural feature is that the bottom of axle is fixed on the bearing, and the bearing on top of axle is by the last cap on the revolving body, has the external screw thread base and fix.

Major advantage of the present utility model:

1, be convenient to dismounting:

Because the top bearing of axle is by the last cap on the revolving body, has the external screw thread base and fixes, and has just simplified staking process one time, for this product of dismounting provides convenience;

2, be not subject to extraneous windage:

The bottom of axle of the present utility model is fixed on the bearing, and irregular wind-force can only be absorbed by bearing, and the bottom of axle no longer is subjected to extraneous windage, has improved the service life of this product.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view of Fig. 1;

Fig. 3 is the split structural representation after the dismounting of the present utility model;

Fig. 4 is the vertical view of Fig. 1.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:

The utility model comprises the revolving body 3 that bearing 1, bearing 1 top are made up of fan blade 8, and axle 9 bottom is fixed on the bearing 1, and the bearing 11 on the top of axle 9 is to be fixed by the last cap 5 on the revolving body 3, base 10 with external screw thread 12.

Can pass through upper and lower plain cushion 7, upper and lower nut 6 is fixed in its axle 9 on the bearing 1.And can adjust the height of revolving body 3 by upper and lower nut 6 with respect to bearing 1.

Narrate the utility model assembling process substantially below:

At first fan blade 8 is riveted on respectively on circular slab 4, the revolution frame 2, above then cap 5, the base 10 with external screw thread 12 is fixing with the bearing on the axle 9 11, and circular slab 4 is also just by last cap 5 simultaneously, and the base 10 with external screw thread 12 is held on wherein; By plain cushion 7, nut 6 is fixed in the bottom of axle 9 on the bearing 1 and gets final product again.

Claims
