Abstract
The utility model discloses a pipe, in particular to a telescopic ventilating pipe, mainly used for indoor ventilation or others, which comprises a folding pipe body [1], and which is characterized in that the inner sides of the pipe body [1] are provided with reinforcement threads [2]. Compared with the prior art, the telescopic ventilating pipe has the advantage of high intensity that stretching, shortening and bending are random, and also has resistance to deformation, in particular to good maintenance of ventilation when the telescopic ventilating pipe is used and impossibility of affecting ventilation by being flattened under compression.
Description
Technical field:
The utility model relates to a kind of tubing, and particularly a kind of telescopic ventilation duct is mainly used in indoor ventilation, or is used for other.
Background technique:
Be used for indoor ventilation duct (as home-use oil extraction smoke pipe etc.) at present and all adopt the software plastic tube, when making, the body of software plastic tube is injection molded into collapsible shape, promptly can elongate as required or shorten, simultaneously also can be arbitrarily crooked, bring convenience to installation, but the shortcoming of this tubing is that body intensity is low very easily distortion behind the pressurized, often occur becoming flat phenomenon in transportation, storage and using process, influence is normally ventilated.
Summary of the invention:
The purpose of this utility model provides a kind of intensity height, on-deformable flexible ventilation duct, overcomes the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of flexible ventilation duct, and it comprises body [1], body [1] is rugosity, it is characterized in that: be provided with reinforced wire [2] in the inboard of body [1].
Described reinforced wire [2] shape in the shape of a spiral is evenly distributed on the inboard trench place of body [1].
The utility model compared with prior art has the high advantage of intensity, both can arbitrarily elongate, shorten and bending, has non-deformability again, particularly in use can keep good ventilation state, and unlikely pressurized becomes flat and the influence ventilation.
Description of drawings:
Fig. 1 is the phase diagram that the body in the utility model embodiment elongates;
Fig. 2 is the phase diagram that the body in the utility model embodiment shortens.
Embodiment:
As shown in the figure: 1 is existing folding body, because body 1 is vertically collapsible, so can elongate and shorten, the while also can be arbitrarily crooked.Inboard trench place at body 1 is provided with reinforced wire 2, described reinforced wire 2 is the plastics silk, into a single integrated structure with body 1, reinforced wire 2 has played the effect of skeleton in body 1, do not influence its flexible and crooked in, increase the intensity of body 1 again, be difficult for pressurized and become flat, in use can keep good ventilation state.Course of working is as follows: utilize plastic extruder processing reinforced wire 2, be that plastic raw material adds hot extrusion through extruder, from head place extrusion plastic silk, the plastics silk of extruding that has temperature (185 ℃) is wrapped in formation reinforced wire 2 on cylindrical mold rotation and that be processed with spiral grooves equably, spring-like shape, reinforced wire 2 are positioned at the place, protruding peak of the spiral grooves on the mould.Use another plastic extruder extrusion plastic film band simultaneously, the banded plastic film that promptly has temperature (185 ℃), be wrapped in the cylindrical mold of rotation and the outside of reinforced wire 2 equably and form folding body 1, because reinforced wire 2 and body 1 are plastic materials and have temperature, twine the cooling back and form an integral body, owing to twine continuously, the continuous demoulding of the tubing that forms on mould is cooled off, and just can obtain having the telescopic plastic tube of software of reinforced wire.The rotation of described cylindrical mold can utilize power plant to drive, by the driven by motor retarder, output shaft and driving component by retarder drives its rotation again, spiral grooves place on the cylindrical mold is provided with the trench top depression bar of a round end, the trench top depression bar is fixed on the frame, when the plastic film band twined on mould, the effect of thorough cut groove compression bar made the tubing of formation the folding groove of spiral occur, guarantees that tubing can be elongated and shorten.In order to have effect preferably, the trench top depression bar can be provided with two or more.Described reinforced wire can utilize plate-like plastics silk or the wire of selling on the market.
