Abstract
The utility model relates to an air duct connection device. The utility model is characterized in that a closed square cylinder (2) is composed of cut corners of four pieces of sectional materials (1) and the structures of the sectional materials are the same; one side of the section material (1) is provided with a plane (3) and the flange (4) of the square cylinder (2) is formed; the other side of the section material (1) is provided with a slot (5) and the annular imbedding slot (6) of the square cylinder (2) is formed; the side surface (7) of the slot (5) makes up the closed inner wall of the square cylinder (2).
Description
The utility model is relevant with wind tube connecting device, and is especially relevant with the connection set of square airduct.
Existing airduct is realized being connected of two airducts with connecting bolt is fastening by the flange plate that airduct two ends and its are connected as a single entity.This Placement since the flange Outside Dimensions greater than the body size, so the size that takes up space is bigger.
The purpose of this utility model provides a kind of simple in structure, and is easy to assembly, and it is little to take up space, connection set attractive in appearance.
The utility model is achieved in that
The utility model is formed closed square tube 2 by identical section bar 1 rescinded angle of four block structures, and a side of section bar 1 has plane 3 to constitute the flange 4 of square tube 2, and the opposite side of section bar 1 has groove 5 to constitute the annular caulking groove 6 of square tube 2, and the closed inwall of square tube 2 is formed in the side 7 of groove 5.
Flange 4 is concordant with the height of caulking groove 6, between the bottom surface 8 of flange 4 and caulking groove 6 is arranged the working clearance, and connecting bolt 9 is arranged between the flange 4.
The height of flange 4 is lower than the height of caulking groove 6, and flange 4 is connected by groove card 10, and the height that flange is equipped with behind the groove card is concordant with caulking groove 6, between the bottom surface of flange 4 and caulking groove 6 is arranged the working clearance.
The utility model flange 4 protrudes the outer wall of caulking groove 6, and the connecting key 11 of flange 4 is connected by groove card 10.
Two flanges 4 of the utility model butt joint constitute T shape, and groove card 10 has similar T-slot.
The utility model connects end face Sealing 12.
The utility model Sealing 12 is a seal ring, is positioned at the seal groove that connects end face.
The utility model flange 4 is the closed ring flange, and caulking groove 6 is a continuous circular shape.
Caulking groove of the present utility model is connected with the two ends of rectangular air duct, available sealer and various fastening piece are fixing as a whole with both, by end-face hole on the flange or connecting key bolt, links such as nut or groove card link together two airducts, and the utility model has following advantage:
1. be specially adapted to the connection of self non-flanged ventilation duct, and easy to connect, reliable, in light weight, intensity is high, specious, good decorating effect.
For wall thickness thicker can't blue thermal insulation wind pipe, after using this device, because the face size of flange is no more than the airduct external diameter, thereby save the bulk that ventilation duct occupies, increase the indoor floor height of building, if calculate,, can increase the first floor sheaf space guaranteeing the identical layer relative superiority or inferiority by 30 floors.
3. the utility model is installed easy to connect, easy to manufacture.Can by a kind of section bar cut different amount make difformity and the size square tube be connected corresponding airduct, low cost of manufacture.
Following is accompanying drawing of the present utility model:
Fig. 1 is the utility model structural drawing.
Fig. 2 is the another kind of structural drawing of the utility model.
Fig. 3 is the another kind of structural drawing of the utility model.
Fig. 4 is the left view of Fig. 1.
Fig. 5 is the left view of Fig. 2.
Fig. 6 is the left view of Fig. 3.
Following is embodiment of the present utility model:
Embodiment 1:
Square tube 2 one ends are flange 4, and the other end has continuous square caulking groove 6.Caulking groove 6 is embedded in the wall of airduct 13, has sealer that both are solidly fixed.Between the bottom surface 8 of caulking groove 6 and the flange 4 arranged the working clearance, flange 4 usefulness bolts 9 connect, thereby two airducts are connected.Square tube 2 is spliced by four section bar 1 rescinded angles, and splicing place can be welded or bond with sealer.
Embodiment 2:
Square tube 2 is the tube of rectangle for the cross section, the discontinuous flange 4 of four lateral projections of one end, and the other end has continuous rectangle caulking groove 6.Caulking groove 6 is embedded in the wall of airduct 13, and available rivet is fastening.Flange 4 has connecting key 11, is connected by groove card 10.
Embodiment 3:
Square tube 2 is the tube of rectangle for the cross section, and the one end is continuous flange 4, and the other end has continuous rectangle caulking groove 6.Caulking groove 6 is embedded in the wall of airduct 13.Available sealer is fastening.Between the bottom surface 8 of caulking groove 6 and the flange 4 there is the working clearance.Connecting key 11 butt joints of flange 4 are T-shaped, cooperate with the T-slot of groove card 10.The height that flange is loaded onto behind the groove card 10 is concordant with wind pipe wall.Draw-in groove 10 is made by rubber-like material such as plastics.Section bar 1 can be made by metallic material or plastics.
