To achieve these goals; The utility model provides a kind of outlet pipe fastening hoop, and this fastening hoop comprises circumferential body portion and the fixing part that stretches out from said circumferential body portion, and said circumferential body portion one has the loop configuration of inner groovy; It is characterized in that; Be formed with a plurality of punching press mouths in the said circumferential body portion, on this punching press mouth, said circumferential body portion extends towards both sides to form and turns edge.
Preferably, the sectional shape of said punching press mouth is roughly rectangle.
Preferably, on this punching press mouth, said turn edge radially outward protrusion and edge form the curve shape of smooth transition.
Preferably, be formed with three said punching press mouths in the said circumferential body portion, these three punching press mouths and said fixing part are evenly distributed in the said circumferential body portion.
Preferably, said fixing part extends radially outwardly from said circumferential body portion.
Preferably, this fastening hoop also comprises fastening piece, and said fixing part is provided with penetration hole, and said fastening piece passes said penetration hole and is installed on the said fixing part.
Preferably, said fastening piece is bolt or Cock screw.
Through technique scheme, only need in the forming process of outlet pipe fastening hoop, to form some punching press mouths, can make things convenient for moulding and make said outlet pipe fastening hoop, and formed outlet pipe fastening hoop intensity is high, be difficult for strain or damage.
Other feature and advantage of the utility model will partly specify in embodiment subsequently.

Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model; Do not doing under the situation of opposite explanation; The noun of locality that uses, that is to say normally for the ring edge of the circumferential body portion of outlet pipe fastening hoop like " inside and outside ", " inside " representative be the circular part that said ring edge surrounds." side " or " side direction " also is for the circumferential body portion of outlet pipe fastening hoop; Refer to two side directions of the inner groovy of circumferential body portion shown in Figure 3, and promptly be a side direction of said fastening hoop as the front-end face of the fastening hoop shown in Figure 1 of plan view.
Extremely shown in Figure 3 like Fig. 1; The utility model provides a kind of outlet pipe fastening hoop, and this fastening hoop comprises circumferential body portion 1 and the fixing part 2 that stretches out from said circumferential body portion 1, and said circumferential body portion 1 one has the loop configuration of inner groovy; As shown in Figure 3; Be formed with a plurality of punching press mouths 3 in the wherein said circumferential body portion 1, on this punching press mouth 3, said circumferential body portion 1 extends towards both sides to form and turns edge 13.In the utility model; To be solved is that the cross section of existing technology is that the outlet pipe fastening hoop of flute profile is by the straight steel plate bending forming of said inner groovy shape the time; The side of outlet pipe fastening hoop is easy to generate irregular fold or pointed protrusion; And in the problem of wiping out the strength deficiency that causes behind the said sharp-pointed protrusion, thereby the utility model forms a plurality of punching press mouths 3 on the outlet pipe fastening hoop, and the outer of formation rule turns edge 13.Like this, after forming a plurality of punching press mouths 3, during by the straight steel plate bending forming of inner groovy shape, the edge of said circumferential body portion 1 can not form sharp-pointed protrusion or fold again, makes things convenient for moulding and manufacturing.And, form punching press mouth 3 through punching press after, the outer wall of the outlet pipe fastening hoop structure that still forms as one, and can not produce breach influence structural strength, on the contrary punching press mouth 3 places turn edge 13 just as in stiffening rib, more can strengthen structural strength.
As shown in Figure 2, the sectional shape of said punching press mouth 3 is roughly rectangle, and promptly the hatching part among Fig. 2 that is to say the centre position at this punching press mouth 3, and the internal surface 12 of circumferential body portion 1 is stamped into almost smooth.On this punching press mouth 3, said turn edge 13 radially outwards protrusions and edge form the curve shape of smooth transition.Also visible from Fig. 1, make the outer surface 11 radially outwards protrusion of circumferential body portion 1 at punching press mouth 3 places after the punching press, so also can reduce 13 the outside extension of turning edge, said certainly turn edge 13 too radially outward protrude.As shown in Figure 2, said 13 the edge of turning edge forms the curve shape of smooth transition, i.e. label among Fig. 2 11 (referring to outer surface) curve pointed.That is to say, after punching press, can not form sharp-pointed protrusion, also just need not wipe out and saidly turn edge 13, can not cause adverse influence moulding and manufacturing.
In this mode of execution, as shown in Figure 1, be formed with three said punching press mouths 3 in the said circumferential body portion 1, these three punching press mouths 3 and said fixing part 2 are uniformly distributed in the said circumferential body portion 1.Equally spaced like this distribution meets stress distribution.And said fixing part 2 extends radially outwardly from said circumferential body portion 1.Said fixing part 2 comprises relative two-part, and two-part are bonded together, and can tighten said outlet pipe fastening hoop.And the outlet pipe fastening hoop of the utility model also can comprise fastening piece 4, and said fixing part 2 is provided with penetration hole 5, and said fastening piece 4 passes said penetration hole 5 and is installed on the said fixing part 4.In this mode of execution, said fastening piece 4 is preferably bolt or Cock screw etc.
The outlet pipe fastening hoop of the utility model is in forming process; Can be earlier with crooked as the both lateral sides of the straight steel plate of strip of former blank and make the cross section of this straight steel plate form the inner groovy shape; Forming a plurality of punching press mouths of formation on the straight steel plate of inner groovy shape, the flexible formation in the vertical two ends outlet pipe fastening hoop as shown in Figure 1 of the straight steel plate of strip after the punching press again.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But the utility model is not limited to the detail in the above-mentioned mode of execution, in the technical conceive scope of the utility model; Can carry out multiple simple variant to the technological scheme of the utility model; For example, can make punching press mouth 3 form square or other shape, these simple variant all belong to the protection domain of the utility model.
