Abstract
The utility model relates to a direct connecting and reveted pressure air pipe without need of flange, consisting of at least two pipe segments(1). The utility model is characterized in that the cross section of the pipe segment(1) takes a square shape; and the pipe segment consists of four single-layer walls. The corresponding four walls of the two pipe segments(1) which are connected with each other are respectively inserted into different grooves of a same H-shaped connecting element(3), and are fastened by a fastening element 4. The four walls of the amounting end of the air pipe are respectively inserted into the groove(5) of the connecting element(2), and are fastened by a fastening element 4. The other grooves(6) of the two connecting elements(2) are both assorted with the same H-shaped button(7). The utility model has the advantages of simple structure, pipe segment production, being convenient for transport and reservation, being capable of being mounted to necessary length, being convenient for connecting one air pipe with another air pipe, high mounting efficiency, and saving the material and time.
Description
Technical field:
The utility model is relevant with the combined type ventilation duct.
Technical background:
Existing riveted type can't be made up of the 2-section pipe section by blue ventilation duct at least, the end face of every pipe joint section is a polygonal, the tube wall port of every limit correspondence is nested with link, link surrounds the closed mouth of pipe, link has keyway, the keyway of the corresponding link of 2-section pipe section is by same connecting key butt joint, and link is connected with tube wall by rivet.Airduct is simple in structure, and is easy to connect, but since airduct in plant produced, its length is fixed, and the job site proposes different requirements to the length of airduct, uses inconveniently, causes a large amount of wastes of material and the loss in man-hour.
Content of the present utility model:
The purpose of this utility model provides a kind of simple in structure, the length of adjutage as required, straight-through riveted type flangeless wind pipe easy to assembly.
The utility model is achieved in that
The utility model leads directly to riveted type flangeless wind pipe, is assembled by 2-section pipe section (1) at least, and the cross section of pipeline section (1) is square, is made of the individual layer wall.The relative wall of the 2-section pipe section (1) that is connected inserts respectively in the different slots of same I-shaped link (3), fastening by fastener 4, the wall of the assembling end of airduct inserts respectively in the groove (5) of link (2), fastening by fastening piece (4), another groove (6) of two links (2) cooperates with same I-shaped key (7).
The cross section of the utility model pipeline section (1) is a rectangle, and its length is 100-3000mm.
The connection termination of the utility model pipeline section (1) scribbles sealant layer.
The utility model is simple in structure, and is with low cost, though pipeline section is produced in batches in factory, a collection of product length is fixed, and owing to the length of pipe section of selecting both has been convenient to low-cost batch process the in batches, also is convenient to transportation and storage.In the assembling job site, can be quick according to environment requirement, firm is assembled into the airduct that meets length with some pipeline sections, and being linked and packed of the airduct after the assembling and other airduct is also very convenient, the join strength height, it is little to take up space, attractive in appearance, decorates and good sealing effect.The utility model installation efficiency height is saved material and man-hour, and labor intensity is low.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Embodiment:
The length of pipeline section 1 is 100-3000mm, and the cross section is a rectangle.After pipeline section 1 termination that is connected is coated with full sealer, insert in the groove of I-shaped link 3, levelling tightens up.At link 3 appropriate location drilling, and fastening, thereby adjusted the length of airduct with self-plugging rivet 4 with pipeline section 1.After the two ends of the airduct that will be connected are coated with full sealer, insert respectively in the groove 5 of link 2, and in position drilling also uses self-plugging rivet 4 fastening, and I-shaped key 7 is inserted in another groove 6 of links 2, thereby realize the connection of two pipes.
Claims (3)
1, straight-through riveted type flangeless wind pipe, at least assemble by 2-section pipe section (1), the cross section that it is characterized in that pipeline section (1) is square, constitute by the individual layer wall, the relative wall of the 2-section pipe section (1) that is connected inserts respectively in the different slots of same I-shaped link (3), and is fastening by fastener 4, and the wall of the assembling end of airduct inserts respectively in the groove (5) of link (2), fastening by fastening piece (4), another groove (6) of two links (2) cooperates with same I-shaped key (7).
2, airduct according to claim 1, the cross section that it is characterized in that pipeline section (1) is a rectangle, its length is 100-3000mm.
3, airduct according to claim 1 and 2 is characterized in that the connection termination of pipeline section (1) scribbles sealant layer.
