Abstract

The utility model relates to a wind pipe connection apparatus, which comprises a rectangular wind pipe body, a card-shaped flange and a cutting wood, wherein the inner edge of one side of the flange is provided with a bayonet which is anastomosing to the end part of the pipe body, and the end part of the pipe body is inserted into the bayonet and connected with the bayonet; the position near the outer edge of the same side of the flange is provided with a slot, and both ends of the slot are communicated with the edge of the flange; the cutting wood is provided with a concave-shaped necking which is matched with the slot on the flange, and the cutting wood is inserted in each slot of four edges of two abutting joint flanges. The utility model uses the cutting wood to be inserted in an F-shaped flange neck formed by abutting joint of two wind pipes to conveniently connect the wind pipes, and the requirement of operating space is not much; the cutting wood generates the combining power to a whole butt side, the action of sealing strips is added, so the sealability of connection is improved, and the phenomenon of 'cold bridge ' can not generate; the heat-insulating properties of the wind pipe body are favorable, and the properties of corrosion resistance, rustiness resistance and weather resistance are good on the surface; the utility model also has the advantages of beautiful appearance, light weight, good rigidity and convenient hoisting.

Description

Airduct bindiny mechanism

Technical field

The utility model relates to a kind of airduct bindiny mechanism, is mainly used in the connection of air conditioner ventilation pipeline.

Background technique

Common flange butt joint is adopted in the connection of existing air conditioner ventilation pipeline, connects by screw at the scene, and is very inconvenient.Especially the less scene in the space is difficult to screw screw-nut with instrument, therefore can not be fully fastening, influence sealing, and profile is not attractive in appearance yet.

Summary of the invention

The purpose of this utility model just provides a kind of airduct bindiny mechanism, and to solve the connection inconvenience that prior art exists, the scene less in the space can not be fully fastening, influences sealing, and the inaesthetic problem of profile.

The technical solution of the utility model is: comprise the airduct body of rectangle, also comprise cassette flange and cutting, be provided with the bayonet socket with the end anastomosis of described body on the interior edge of this flange one side, the end of body is inserted in this bayonet socket and is interconnected; Place, close outer in described flange the same side is provided with slot, and the two ends of this slot communicate with flange periphery; Described cutting is provided with the spill reducing that matches with slot on the described flange, all is inserted with this cutting in the slot on four limits of described two abutted flanges.

Opposite side at described cassette flange is provided with sealed groove and the Stamping Steel Ribbon that places in it.

There are two kinds of shapes the end of described cutting, and wherein a kind of two ends of cutting are 45 ° of oblique angles; An another kind of end of transplanting a cutting is 45 ° of oblique angles, and the other end is a tack.

Described airduct body is composited by the clean colored steel of the high strength of thermal insulation layer and its both sides.

In the draw-in groove of the end that the utility model utilization is inserted in two airducts to together cassette flange, just can easily airduct be connected, save installing space; Cutting all produces combination force to whole interface, adds the effect of Stamping Steel Ribbon, has improved the sealing that connects greatly, can not produce " cold bridge " phenomenon; Airduct body surface forms with the thermal insulation layer one step press, and high-efficiency insulated, inner and outer surface is corrosion-resistant, corrosion resistant, good weatherability; Beautiful shape, in light weight, good rigidity is convenient to lifting.

Embodiment

Referring to Fig. 1～Fig. 6, the utility model comprises the airduct body 1 of rectangular cross-section, all be connected with cassette flange 2 and spill reducing in the end of the butt joint of described two bodys 1 and transplant a cutting 3 (3 '), be provided with the bayonet socket 21 with the end anastomosis of described body 1 on the interior edge of these flange 2 one sides, the end of body 1 is inserted in this bayonet socket 21 and by drift bolt 6 and is interconnected.Place, close outer in described flange 2 the same sides is provided with slot 22, and the two ends of this slot 22 communicate with flange 2 edges, so that cutting 3 (3 ') are inserted.Described cutting 3 (3 ') is provided with the spill reducing that matches with slot 22 on the described flange 2, all is inserted with a root cutting 3 (3 ') on four limits of described two abutted flanges 2.

Also can be provided with sealed groove 23, and place Stamping Steel Ribbon 5 within it, increase sealing at the opposite side of described cassette flange 2.

There are two kinds of shapes the end of described cutting, and wherein a kind of two ends of cutting 3 are 45 ° of oblique angles; Another kind of transplant a cutting 3 ' an end be 45 ° of oblique angles, the other end is a tack.One even mechanism need two two ends to be the cutting 3 at 45 ° of oblique angles, need two one ends be 45 ° of oblique angles, the other end be tack cutting 3 '.The cutting 3 of tack ' be can be inserted in the draw-in groove 22 for a root cutting that can make last insertion.
