Description

Ventilating fan is formed structure

Technical field

The utility model relates to a kind of ventilating fan, and particularly a kind of ventilating fan is formed structure.

Background technique

Traditional ventilating fan is by a frame pedestal A, fan B, one bearing support C, belt pulley D, bearing E, supporting base F, motor seat G, motor H, belt I forms (seeing also shown in Figure 1), because of its bearing support is locked on the frame pedestal by screw, as belt pulley D, bearing E, fan B, when motor H etc. install, because of having the space of adjustment, locking screw can't not reach a state of equilibrium, cause the rotating center imbalance of fan B that shift phenomenon is arranged, cause the vibration of belt pulley D rotating shaft, have influence on bearing E, the generation of belt I and motor H working life and noise, the composition of another kind of ventilating fan is the same with above-mentioned composition, add a spring J in motor seat lower end but have, living by motor seat G is fixed in bearing support F and goes up movable relation, catches on the motor seat by spring J and adjusts the tension force of revolution motor belt I and make an equilibrium function motor H is turned round smoothly; See also Fig. 2 and Fig. 3, but bearing support C still is fixed by the screw locking, ventilating fan is equipped with eccentric problem generation, and above-mentioned disappearance can be wasted electric power, and bearing E and belt I also damage easily and cause cost to increase, and the end falls in benefit, is badly in need of solving improvement.

Summary of the invention

The purpose of this utility model provides a kind of ventilating fan and forms structure, its bearing support by on adjustable open-work and the frame pedestal mutually the open-work open-work of the supporting base of corresponding setting arrange in pairs or groups mutually before the adjustment, after, a left side, right position, make ventilating fan be installed on the frame pedestal central position, and set firmly a spring in motor seat below, be fixed in relation movable on the bearing support by the work of motor seat, catch on the tension force of motor seat adjustment revolution motor belt by spring and make an equilibrium function, motor is turned round smoothly, ventilating fan rotates in a center all the time like this, its motor belt is durable in use, reaches the saving installation work-hour, save the energy, the effect that reduces cost.

Ventilating fan of the present utility model is formed structure and is comprised: a frame pedestal, fan, a bearing support, belt pulley, bearing, spring, supporting base, motor seat, motor, belt; The two ends, the left and right sides of described bearing support contain on the open-work established and the frame pedestal mutually the open-work of the supporting base of corresponding setting and arrange in pairs or groups mutually and lock with screw, described bearing support is provided with bearing and is locked by screw in nearly center, edge buries a belt pulley and set firmly a fan in the rotating shaft of belt pulley front end in the rotation open-work of bearing, belt pulley is inserted in a belt and is driven by motor, this motor is fixed on the motor seat, the open-work that the motor seat passes the open-work of motor seat and bearing support by a screw rod arrives the other end and by nut locking, and installs a spring in its pedestal lower end and reach a balance with the tension force of adjusting belt;

It is characterized in that: this bearing support contains establishes adjustable open-work, and described bearing support is by the open-work open-work of the supporting base of the corresponding setting adjustment position, front, rear, left and right of arranging in pairs or groups mutually mutually on adjustable open-work and the frame pedestal, and locks with screw.
