Abstract

The utility model discloses a riveted structure of fan, include that diaphragm and riser and columniform rivet the strip, the border of diaphragm and riser turns over to roll over there is the semicircle bulge loop, the inner chamber both sides of riveting the strip are equipped with the card slot, the inner chamber of card slot is equipped with the semicircle draw -in groove of corresponding semicircle bulge loop, the radius of semicircle draw -in groove is less than the radius of semicircle bulge loop, and this fan adopts the cooperation of riveting semicircle draw -in groove that the strip was equipped with and semicircle bulge loop to realize the riveted structure, the elasticity of semicircle bulge loop make the fan to seal a combination inseparabler, the condition that is difficult for appearing leaking out appears and to rivet the stable in structure of strip higher, improve life, and this structural grouping is various, the production of being convenient for improves production efficiency.

Description

A kind of riveted structure of blower fan

Technical field

This utility model relates to riveted structure technical field, is specially the riveted structure of a kind of blower fan。

Background technology

Blower fan is the tubing for air conveying and distribution, use extremely wide in building and industrial trade, traditional blower fan adopts stainless steel material to be made by the mode welded or rivet all mostly, although adopting the mode Stability Analysis of Structures of welding, but in the process used, owing to the waste gas of factory is acid or alkalescence is higher, corrosivity is bigger, there will be the situation of gas leakage under long-time use to occur, and traditional riveting method adopts the mode of turnover pressing, structural stability is poor, long-time use there will be deformation, the situation of gas leakage, for this, it is proposed that the riveted structure of a kind of blower fan。

Utility model content

The purpose of this utility model is in that to provide the riveted structure of a kind of blower fan, with the problem solving to propose in above-mentioned background technology。

For achieving the above object, this utility model provides following technical scheme: the riveted structure of a kind of blower fan, riveting bar including transverse slat and riser and cylinder, the edge turnover of described transverse slat and riser has semicircle bulge loop, the inner chamber both sides of described riveting bar are provided with board slot, the inner chamber of described board slot is provided with the semicircle draw-in groove of corresponding semicircle bulge loop, and the radius of described semicircle draw-in groove is less than the radius of semicircle bulge loop。

Preferably, the turnover mode of described semicircle bulge loop has four kinds, and the inner chamber of riveting bar is provided with the semicircle draw-in groove of corresponding semicircle bulge loop。

Preferably, outside the edge of described transverse slat and riser, turnover has semicircle bulge loop。

Preferably, inside the edge of described transverse slat and riser, turnover has semicircle bulge loop。

Preferably, outside the edge of described transverse slat and the inner side at the edge of riser has all turned down semicircle bulge loop。

Preferably, inside the edge of described transverse slat and the outside at the edge of riser has all turned down semicircle bulge loop。

Preferably, the inwall of described board slot is pasted with sealing gasket。

Compared with prior art, the beneficial effects of the utility model are: this blower fan adopts the semicircle draw-in groove that riveting bar is provided with to realize riveted structure with coordinating of semicircle bulge loop, the elasticity of semicircle bulge loop makes the sealing part of blower fan combine tightr, not easily occur that situation about leaking out occurs and the Stability Analysis of Structures of riveting bar is higher, improve service life, and this structural grouping is various, it is simple to produce, improve production efficiency。
