Technical field

The present invention relates to blower technical fields, and in particular to a kind of auxiliary support bracket for fan air drum.

Background technique

Air duct is the wind guide component of blower, is generally fixed on blower, due to the length of some air ducts is longer, quality compared with Greatly, it if be directly anchored on blower, will increase the load of blower, lead to its deformation etc., so air duct is generally fixed to air duct On bracket.And existing air duct bracket and air duct are all that correspondingly, an air duct bracket cannot be applicable in multiple air ducts；And by Each air duct bracket generally is not ensured that since the height of air duct bracket is different with the concentric fixation of air duct in air duct bracket Certain effect for starting support.

Summary of the invention

The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of auxiliary support bracket for fan air drum, It can not only be applicable in multiple air ducts within the scope of certain diameter, and not high to the concentricity requirement of air duct and bracket, can be with Load bearing support is played the role of in guarantee.

The solution to the technical problem of the present invention is as follows:

A kind of auxiliary support bracket for fan air drum, including pedestal are fixed with semicircle support plate on the pedestal, and half It is fixedly connected with dismountable circular arc pressing plate in circle support plate, is respectively fixed with multiple pressures on the semicircle support plate and circular arc pressing plate Tight component, the air duct of blower are clamped between multiple hold down assembly.

Described to hold down assembly including compact heap, the inner sidewall of compact heap is pressed against on the outer wall of air duct, the outside of compact heap Be fixed on wall screw rod and with screw rod spring loop bar disposed in parallel, be bolted with two locking nuts, spring pocket on each screw rod Spring is socketed on bar；

The screw rod to hold down assembly in semicircle support plate and spring loop bar sleeve are set in semicircle support plate, two locks Tight nut is separately positioned on the outside and inside of semicircle support plate, inner sidewall and compact heap of the spring clamping in semicircle support plate Between lateral wall；

The screw rod to hold down assembly on circular arc pressing plate and spring loop bar sleeve are set on circular arc pressing plate, two locking screws Mother is separately positioned on the outside and inside of circular arc pressing plate, spring clamping circular arc pressing plate inner sidewall and compact heap lateral wall it Between.

Two ends of the semicircle support plate respectively form first trunnion an of fold inward, and two of circular arc pressing plate End respectively forms second trunnion an of fold inward, and the second downwardly convex screw rod, the second spiral shell are fixed on the second trunnion Bar is screwed onto the upper end of threaded sleeve, and the lower end of threaded sleeve is fixed in stepped cylinder；Formed on first trunnion with Through-hole, for the small end cylinder sleeve of stepped cylinder in through-hole, the big end cylinder of stepped cylinder is located at the lower section of the first trunnion.

The spring loop bar, which has, is socketed with spring on two and every spring loop bar, two spring loop bars are symmetrically arranged Screw rod two sides.

For one end sleeve of the spring loop bar far from compact heap in guiding column sleeve, guiding column sleeve is fixed on semicircle support plate Inner wall on or the inner wall of circular arc pressing plate on.

It is arranged in there are five the numbers to hold down assembly in semicircle support plate, wherein three hold down assembly and are evenly arranged on semicircle branch The bottom of fagging, other two, which holds down assembly, is separately positioned on the both ends of semicircle support plate, in the screw rod each to hold down assembly Mandrel line is overlapped with the center of circle of semicircle support plate；

It is arranged in there are three the numbers to hold down assembly on circular arc pressing plate, one of them, which holds down assembly, is arranged in circular arc pressing plate Top, other two, which holds down assembly, is separately positioned on the both ends of circular arc pressing plate, the central axis of the screw rod each to hold down assembly It is overlapped with the center of circle of circular arc pressing plate.

That compact heap face to hold down assembly of three centres to hold down assembly of the bottom of semicircle support plate is evenly arranged on to set Set the compact heap to hold down assembly on the top of circular arc pressing plate.

Protrusion effect of the invention is: compared with prior art, it can not only be applicable in multiple within the scope of certain diameter Air duct, it is and not high to the concentricity requirement of air duct and bracket, it is ensured that play the role of load bearing support.
