Description
[technical field]
The utility model relates to the seamless negative pressure air duct of a kind of novel coated cloth, belongs to industrial basic fittings manufacturing technology field.
[background technology]
As everyone knows, the existing negative pressure air duct in mine can be divided into hard sizing air duct and the large class of extension air tube two.Hard ventilating tube generally adopts flange to connect, or pvc material is bonding, connects technique loaded down with trivial details, particularly can not flexible adaptation environment for use, and it is large to take up space; It is large that scalability air duct exists again windage, and resistance to negative pressure ability is low, and transposing is required to the shortcomings such as strict.These, bring difficulty all to the popularization of exhaust ventilation mode above.
In addition, the connection between traditional negative pressure air duct is equal is to adopt end circle, with cloth, is pressed together on cylindrical shell, such negative pressure air duct connects insecure, makes windage large, and air leak rate of air curtain is high, for overcoming above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
[utility model content]
The purpose of this utility model is: for defect and the deficiency of prior art, provide a kind of simple in structure, the seamless negative pressure air duct of a kind of novel coated cloth reasonable in design, easy to use, change the connected mode between original air duct, not only for convenience detach, and can be good at air duct to be fixed, thering is good ductility, cost compare is low.
For achieving the above object, the technical solution adopted in the utility model is:
The seamless negative pressure air duct of a kind of novel coated cloth described in the utility model, comprise spiral wire, on spiral wire, be enclosed with coated cloth, the end that is provided with of coated cloth encloses, the outer wall of coated cloth is evenly provided with press strip and suspension ring, described suspension ring comprise main hoisting ring and secondary suspension ring, and main hoisting ring and secondary suspension ring distribute alternately on the surface of coated cloth, and the end of coated cloth is also provided with snap joint; Described snap joint comprises annular fixing member, fastening stud and fastening base, the upper and lower end of annular fixing member is provided with turnover slotted eye, in turnover slotted eye, is provided with iron wire ring, by iron wire ring, is communicated with turnover slotted eye, the iron wire ring one end of stretching out turnover slotted eye is provided with fastening stud, and the other end is provided with fastening base.
In the utility model: described fastening stud comprises fixed dam two, one end of fixed dam two is provided with handle, and the other end is provided with screw rod, and screw rod is provided with screw thread, and screw rod is connected with gland, and wherein the both sides of fixed dam two are respectively equipped with sliding mouthful.
In the utility model: described fastening base comprises fixed dam one, fixed dam one is provided with screw, and the both sides of screw are respectively equipped with the aperture passing for iron wire ring.
Adopt after said structure, the utility model beneficial effect is: the utility model is simple in structure, reasonable in design, easy to use, by the end at coated cloth, change the connected mode between original air duct, increased a snap joint, not only for convenience detach, and can be good at air duct to be fixed, make windage little, at the bottom of air leak rate of air curtain, have good ductility, cost compare is low.
