Abstract
The utility model discloses a spiral wind outlet pipe, and the vertical cross section of which possesses a wave shape composed of a wave crest and a trough. The utility model is characterized in that the wave crest of the pipe wall is supported with a spiral spring steel wire. The preferential scheme of the utility model is that the pipe wall adopts the double layer structure, and the spring steel wire is clamped between an inner and an outer pipe wall. The utility model has the advantages of none deformation, small wind resistant coefficient and flowing wind discharge, particularly suitable for the connection with the wind outlet of the oil and smoke machine.
Description
Technical field
The utility model relates to air outlet tube, is a kind of screw type air outlet tube specifically.
Background technique
In numerous processes of producing and living, the oil smoke that some apparatus or equipment produced, waste gas, flue gas etc. need be discharged the environment at these apparatus or equipment place with it with pipeline, usually, need between these apparatus or equipment and the pipeline to be connected with flexible air outlet tube.Such as: the oil smoke that the kitchen fume machine extracts need be discharged outdoor usually or row advances public flue, this just need connect air outlet tube on the exhaust outlet of kitchen ventilator, thereby again by the hole of air outlet tube on wall stretch out outdoor oil smoke is derived outdoor, thereby the flue gas inlet that perhaps connects public flue by air outlet tube is arranged into public flue with oil smoke.At present, in the installation process of kitchen ventilator, kitchen ventilator exhaust outlet and public flue or outdoor between used air outlet tube all be to adopt flexible bellows basically.Bellows is divided into common bellows and screw type corrugated pipe again on structure, both common ground are that structural pipe wall is an individual layer, the longitudinal section is the waveform with crest and trough, and difference is: the former crest, trough are the closed circle of endless tube wall, and the latter then is the spirality of endless tube wall.In actual use, find that the defective of distortion such as depression takes place easily in existing these bellowss existence, and distortion in a single day, distortion is difficult to recover, thereby forms windage, influences the unobstructed property of air-out.Moreover existing bellows is to make it have certain non-deformability, and its crest, trough place have the effect of certain reinforcement usually, thereby the degree of drawing back when drawing back is restricted, inwall fold after causing air outlet tube to draw back is a lot, and level and smooth inadequately, air resistance coefficient is bigger.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of not yielding and screw type air outlet tube that air-out is unobstructed is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this screw type air outlet tube, the longitudinal section of its tube wall is the waveform with crest and trough, it is characterized in that the crest place of described tube wall is supported with the spiral spring steel wire.
Described tube wall is the double layer construction that is bonded to one by inner layer tube wall and outer wall, and described Spring Steel Wire promptly is clipped between inner layer tube wall and the outer wall.Tube wall is the fixing and location that double layer construction helps Spring Steel Wire.
Described inner layer tube wall, outer wall are aluminium foil material or flame-proof PVC material.
The described Spring Steel Wire of port, described tube wall two ends is coated with aluminium foil or flame-proof PVC.The port steel wire both can prevent that steel wire from hurting sb.'s feelings after coat handling, can prevent that again steel wire from getting loose.
The diameter of described Spring Steel Wire is 0.8～2mm, and diameter is too little, and then holding strength is inadequate slightly, diameter is too big, and then cost increases on the one hand, may influence the bending deflection of air outlet tube on the other hand because of elasticity too greatly, the influence factor of comprehensive two aspects, preferred diameter is 1.2mm.
Advantage of the present utility model is: compare with existing bellows, because the support to air outlet tube is finished by Spring Steel Wire basically, thus its to draw back degree bigger, that is to say that the variable pitch of pitch is bigger, make the stretching back of air outlet tube inwall level and smooth, air resistance coefficient is smaller; Adopt the Spring Steel Wire supporting structure to make air outlet tube be difficult for distortion, air-out is unobstructed; Aluminium foil or PVC material are flame-proof material, have eliminated disaster hidden-trouble.

Fig. 1 is model utility embodiment's a structural representation;
Fig. 2 is the A place broken section enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment
As shown in Figure 1 and Figure 2, be a better embodiment of the present utility model.As shown in Figure 1 and Figure 2, present embodiment screw type air outlet tube, the longitudinal section of its tube wall 1 is the waveform with crest 2 and trough 3, it is the spiral spring steel wire 4 of 1.2mm that crest 2 places of tube wall 1 are supported with the corresponding to diameter of the spiral of crest 2, tube wall 1 is the double layer construction that is bonded to one by inner layer tube wall 101 and outer wall 102, and Spring Steel Wire 4 promptly is clipped between inner layer tube wall 101 and the outer wall 102.
Described inner layer tube wall 101, outer wall 102 can be aluminium foil material or flame-proof PVC material, and present embodiment is selected aluminium foil for use, and the Spring Steel Wire 4 of port, tube wall 1 two ends is coated with aluminium foil.
