Abstract

The utility model discloses a connecting structure of a shell of an air blower. The connecting structure comprises a front shell and a rear shell which are provided with a front air pipe and a rear air pipe respectively, the front air pipe and the rear air pipe are assembled to form an air outgoing pipe, a port of the air outgoing pipe extends outwards to form an annular boss, a plastic cover is connected on the annular boss in a sleeved manner, a round hole used for air outgoing is formed in the middle of the plastic cover, the inner side wall of the plastic cover extends towards the interior of the plastic cover to form a clamping platform, a clamping groove is formed between the clamping platform and the inner wall of the plastic cover, and the annular boss is connected at the clamping groove in a clamped manner to fix the plastic cover on the air outgoing pipe. The plastic cover is connected on the annular boss in a sleeved manner, so that cracking of the shell of the air blower can be effectively prevented, the front shell and the rear shell can be prevented to form a gap at the air outgoing pipe, air quantity blown in other equipment from the air blower cannot be reduced, and production efficiency can be greatly improved.

Description

A kind of linkage structure of blower drum
Technical field
The utility model relates to the linkage structure of a kind of blower, particularly a kind of blower drum.
Background technique
Generally all be provided with air outlet tube on the shell of blower, after wind enters blower inside from intake grill, under the effect of impeller, from air outlet tube, blow out again, therefore the air outlet tube place of blower can be subject to the pressure-acting of air-flow, and the shell of blower is all generally to be assembled by fore shell and back cover, therefore under the pressure-acting of the air-flow at air outlet tube place, the easy cracking phenomenon of fore shell and back cover, the working life of so just having reduced blower drum.In addition, under the pressure-acting of air-flow, between the protecgulum at air outlet tube place and bonnet, also can produce gap, the wind that causes the air outlet tube place leaks in outside atmosphere and goes, and can make like this manufacturing efficiency be affected.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of linkage structure that can effectively prevent generation gap, air outlet tube place, blower drum simple in structure.
The utility model solves the technological scheme that its technical problem adopts:
A kind of linkage structure of blower drum, comprise fore shell and back cover, be respectively equipped with front airduct and rear airduct on described fore shell and back cover, described front airduct and the assembling of rear airduct form airduct, the port of described air outlet tube is outward extended with annular boss, be socketed with vinyl cover on described annular boss, the internal diameter of described vinyl cover is than the large 0.1 ~ 0.3mm of the external diameter of annular boss, the middle part of described vinyl cover is provided with the circular hole for air-out, the madial wall of vinyl cover is extended with Ka Tai towards its inside, form draw-in groove between the inwall of described Ka Tai and vinyl cover, thereby described annular boss is connected to the draw-in groove place vinyl cover is fixed on air outlet tube.
In the utility model, the internal diameter of described circular hole equates with the internal diameter of air outlet tube port.
The beneficial effects of the utility model are: the utility model by being socketed with vinyl cover on annular boss, can effectively prevent the shell cracking phenomenon of blower, and can effectively prevent that fore shell and back cover are in generation gap, air outlet tube place, the air quantity that is blown into miscellaneous equipment from blower so just can not reduce, and therefore can greatly enhance productivity.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is decomposing schematic representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of linkage structure of blower drum, comprise fore shell 1 and back cover 2, be respectively equipped with front airduct and rear airduct on described fore shell 1 and back cover 2, described front airduct and the assembling of rear airduct form airduct 3, the port of described air outlet tube 3 is outward extended with annular boss 4, on described annular boss 4, is socketed with vinyl cover 5, and the middle part of described vinyl cover 5 is provided with the circular hole 6 for air-out.As of the present utility model preferred, the internal diameter of described circular hole 6 equates with the internal diameter of air outlet tube 3 ports.The internal diameter of described vinyl cover 5 is than the large 0.1 ~ 0.3mm of the external diameter of annular boss 4, the madial wall of vinyl cover 5 is extended with card platform 7 towards its inside, form draw-in groove 8 between the inwall of described card platform 7 and vinyl cover 5, thereby described annular boss 4 is connected to draw-in groove, 8 places are fixed on vinyl cover 5 on air outlet tube 3.The utility model by being socketed with vinyl cover 5 on annular boss 4, can effectively prevent the shell cracking phenomenon of blower, and can effectively prevent that fore shell 1 and back cover 2 are in air outlet tube 3 generation gaps, place, the air quantity that is blown into miscellaneous equipment from blower so just can not reduce, and therefore can greatly enhance productivity.
The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
