Abstract

The utility model relates to a wind pipe connecting device which comprises a wind pipe and a U-shaped plate, wherein the U-shaped plate is arranged on the end surface of the wind pipe, and is inversely inserted in both walls of the wind pipe. A special-shaped plate is arranged on the U-shaped plate, one edge of the special-shaped plate is attached to the U-shaped plate, and the other edge is provided with a bent surface which extends to form an E-shaped structure with the U-shaped plate. The other opposite wind pipe is likewise provided with an E-shaped structure. A special-shaped fastener is provided with a plane surface, the middle of the plane surface is provided with a through hole and both sides of the plane surface are provided with long bent surfaces. A short bent surface is arranged behind the plane surface, and the lower end of the short bent surface is inserted in a groove composed of the special-shaped plate and the U-shaped plate. Two adjacent wind pipes are oppositely provided with special-shaped fasteners, and the corresponding special-shaped fasteners are fixedly connected through a bolt assembly. The utility model adopts the E-shaped structure, and the strength is improved. A galvanized plate is used for flange material, and the cost is reduced. The utility model adopts a fastening device, the installation and the maintenance are convenient and the interchange ability is enhanced. The utility model uses the galvanized plate to substitute for harmful PVC material, and is favorable to environmental protection.

Description

Wind tube connecting device

Technical field

The utility model relates to a kind of connection set of airduct, is meant the wind tube connecting device of a kind of E of employing type structure and bayonet unit especially.

Background technique

The used adpting flange material of composite sheet material airduct generally has angle steel, aluminum alloy and PVC in the ventilation and air conditioning engineering at present, the flange of making of angle steel and aluminum alloy is the cost height not only, and the manufacturing procedure complexity, is easy to generate the pitch-row deviation, bring difficulty to installation, general interchangeability is very poor; And the flange that adopts the PVC material can adopt I-shaped quickset type, dovetail type and collude Placement such as locking-type, yet adopt I-shaped quickset type and dovetail type structure because the restriction of wind-engaging length of tube and mounting point, difficulty is installed, be difficult for being inserted into the position, simultaneously because there is the composition that environment is had pollution in PVC material itself, health of human body is impacted, and PVC material flange is aging easily; If do the flange material with common galvanized sheet, though with low cost, light is done flange with it and is existed insufficient strength, easy deformation, thus interchangeability is affected; Therefore, how to provide that a kind of both costs are cheap, environmental protection, interchangeability is good and the life-span is long wind tube connecting device become the difficult problem that industry need solve.

The model utility content

The purpose of this utility model is to provide a kind of wind tube connecting device, adopts E type structure and bayonet unit, can solve foregoing problems effectively.

The utility model purpose adopts following technical proposals to realize:

A kind of wind tube connecting device, include airduct, the U template, the U template is located at the end face of airduct, U template back-off inserts airduct two walls, the U template is provided with special-shaped plate, special-shaped plate is affixed on the U template on one side, and another side is established folding surface, and folding surface stretches out with the U template and constitutes E type structure, another relative airduct is provided with E type structure too, special-shaped buckle is provided with the plane, is provided with through hole in the middle of the plane, and the both sides, plane are equipped with long folding surface, establish short folding surface behind the plane, insert in the groove of special-shaped plate and U template formation short folding surface lower end, and adjacent two airducts are equipped with special-shaped buckle relatively, are connected with bolt assembly between corresponding special-shaped buckle; Bolt assembly includes bolts and nuts.

The utlity model has following advantage:

1. the utility model has adopted E type structure, has increased intensity, can use galvanized sheet to do the flange material, greatly reduces cost.

2. the utility model has adopted bayonet unit, and I﹠M is all very convenient, and has strengthened interchangeability.

3. the utility model has been abandoned environmentally harmful PVC material, environmental protection more.
