Abstract
The utility model relates to a flexible coupling structure which comprises first and second angle steel flanges oppositely arranged and a flexible coupling for connecting the two angle steel flanges, wherein the first angle steel flange is used for being connected with an air inlet; and the second angle steel flange is used for being connected with an air outlet. The flexible coupling structure is characterized by also comprising a protection sleeve positioned in the flexible coupling, wherein the protection sleeve is provided with a first end and a second end; the first end extends to the inside of the first angle steel flange and is fixedly connected with the inner surface of the first angle steel flange; and the second end extends to the inside of the second angle steel flange. The flexible coupling structure has the advantages of reasonable structure, convenience for installation, good sealing performance, reduction of production and overhauling cost and overhauling workload and long service life.
Description
Technical field
The utility model relates to Fan Equipment, specifically a kind of flexible connection structure.
Background technique
Blower fan be flexible coupling be widely used in civilian, the ventilation duct of industrial building and fire-fighting smoke exhaust system.Be flexible coupling and play an important role in pipeline switching, and can also can reduce the common shake producing between blower fan and air channel to the redeeming of expanding with heat and contract with cold causing because of temperature variation, play the effect of quiet noise reduction.Routine is flexible coupling and generally adopts nonwovens, when there is temperature at the scene of blower fan or has in certain corrosive situation, just adopts being flexible coupling of silicone rubber material.But, too high when the blast of blower fan, when inlets and putlets of ventilation is excessive, be flexible coupling under the effect of alternate load, can produce fatigue failure, cause the leakage of medium.
Model utility content
The utility model object is to solve the problem that may cause dielectric leakage in prior art, proposes a kind of novel flexible connection structure.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of flexible connection structure, comprise, be oppositely arranged first, two angle steel flanges be connected being flexible coupling between this two angle steel flange, wherein, this first angle steel flange is for being connected with intake grill, this second angle steel flange is for being connected with exhaust outlet, it is characterized in that, also comprise that one is positioned at the protecting jacket that this is flexible coupling, this protecting jacket has a first end and one second end, this first end extends in this first angle steel flange and is fixedly connected with its inner face, this second end extends in this second angle steel.
As a kind of preferred version of flexible connection structure, this is flexible coupling for nonwovens, silastic fabric or wired silastic fabric.
As a kind of preferred version of flexible connection structure, rivet is passed through with this two angle steel flange respectively in this end being flexible coupling.
As a kind of preferred version of flexible connection structure, this protecting jacket is cylindrical shape, and its internal diameter dwindles gradually from this first end to this second end.
Compared with prior art, advantage of the present utility model: rational in infrastructure, easy for installation, good airproof performance, reduce production maintenance cost and maintenance workload, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Lower surface camber elaborates to the utility model in conjunction with the accompanying drawings and embodiments.
Refer to Fig. 1, shown in figure is a kind of flexible connection structure, mainly by be oppositely arranged first, two angle steel flanges 1, 4, rivet is connected to silicone rubber between this two angle steel flange and is flexible coupling 2 and be positioned at this lining steel plate protecting jacket being flexible coupling 3 compositions, wherein, this first angle steel flange is for being connected with intake grill, this second angle steel flange is for being connected with exhaust outlet, this protecting jacket has a first end and one second end, this first end extends in this first angle steel flange and is welded to connect with its inner face, to fix whole protecting jacket, it is slightly less than first end that this second end extends to this second angle steel opening interior and the second end.
Be not difficult to find out, use said structure, can avoid pressurized gas to cause fatigue fracture with directly repeatedly clashing into of being flexible coupling.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
