Abstract

The utility model provides a shockproof structure of a fume extractor, which comprises a shockproof fixed ring and a mounting ring formed on a motor, wherein, the shockproof fixed ring is provided with an inner ring and an outer ring, and a shockproof elastic ring is connected between the inner ring and the outer ring. After the technical proposal is adopted, the motor is installed on the end surface of the inner ring of the shockproof fixed ring, and the outer ring of the shockproof fixed ring is fixed on a spiral casing. During the work, the shock generated by the motor and the wind wheel is effectively absorbed by the shockproof elastic ring, therefore, the shockproof structure can not only perform shockproof and noise reducing functions, but also prevent the screw from getting loose, the structure is simple and the design is reasonable.

Description

A kind of shockproof structure of smoke exhaust ventilator

Technical field:

The utility model relates to the smoke exhaust ventilator technical field, refers in particular to a kind of shockproof structure of smoke exhaust ventilator.

Background technology:

Owing to producing, driven by motor wind wheel high speed rotating shakes and noise during smoke exhaust ventilator work, in order to reduce the influence of this vibrations, traditional method is to be placed with the elasticity trembleuse cup between fixed head and motor, by screw the elasticity trembleuse cup is pressed between motor installing ring and the fixed head during installation, above-mentioned traditional scheme produces following three problems:

1. because the elasticity trembleuse cup is thin, fail to play effectively the effect that absorbing vibration alleviates noise.

2. when screw overwinded, the elasticity trembleuse cup was compressed and the cushioning effect that follows the string by brute force.

3. when screw threads De Taisong, the vibrations that motor and wind wheel produce when work can be made screw and be got loose.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of shockproof structure of smoke exhaust ventilator to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of shockproof structure of smoke exhaust ventilator, include shockproof retainer ring and the installing ring that is molded on the motor, ring and outer shroud in described shockproof retainer ring is provided with are connected with shockproof elastic ring between interior ring and the outer shroud.

The installing ring that is provided with power supply machine on interior ring is installed the through hole of usefulness.

After adopting technique scheme, motor is installed on the end face of interior ring of shockproof retainer ring, the outer shroud of shockproof retainer ring is fixed on the spiral case, the vibrations that motor and wind wheel produce during work are effectively absorbed by shockproof elastic ring, not only can produce shockproof noise reduction effect but also can prevent that screw from getting loose, simple in structure, reasonable in design.

Fig. 1 is the three-dimensional exploded view of shockproof retainer ring of the present utility model and motor;

Fig. 2 is the cutaway view Amplified image of A part among Fig. 1;

Fig. 3 is the shockproof retainer ring of utility model and the cutaway view after the motor assembling;

Fig. 4 is the cutaway view Amplified image of B part among Fig. 3.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

As attached illustrated in figures 1 and 2, the shockproof structure of this smoke exhaust ventilator includes shockproof retainer ring 1 and the installing ring 3 that is molded on the motor 2, ring 4 and outer shroud 5 in described shockproof retainer ring 1 is provided with, be connected with shockproof elastic ring 6 between interior ring 4 and the outer shroud 5, the installing ring 3 that is provided with power supply machine 2 on interior ring 4 end faces is installed the through hole 7 of usefulness, motor 2 is installed on interior ring 4 end faces of shockproof retainer ring 1 during assembling, and the outer shroud 5 of shockproof retainer ring 1 is installed on the spiral case flexible connection face, and the vibrations that motor 2 and wind wheel produce during smoke exhaust ventilator work all can be absorbed by shockproof elastic ring 6.
