Abstract
The utility model belongs to the technical field of building materials and discloses a signal-seam rectangular air pipe. The signal-seam rectangular air pipe is provided with an air pipe body and is characterized in that the cross section of the air pipe body is of a rectangular shape, the joint portion of the pipe walls of the air pipe body is of single-seam connection, the single-seam connection portion comprises a lower protruding edge, an upper protruding edge, an upper seam edge and a lower seam edge, the left air pipe wall joint portion is provided with the lower protruding edge protruding downwards and the upper seam edge, the right air pipe wall joint portion is provided with the upper protruding edge and the lower seam edge, the upper seam edge is arranged between the upper protruding edge and the lower seam edge in an inserting mode, the lower seam edge is arranged between the lower protruding edge and the upper seam edge in an inserting mode, the joint portion of the left air pipe wall is meshed with the joint portion of the right air pipe wall, and the sealing performance is greatly improved. The signal-seam rectangular air pipe has the advantages that a galvanized iron pipe is adopted, occupied space is small, comprehensive investment is low, operation cost is low, the sealing performance and stability are good, and the development direction is good from the aspects of economic benefits and the strategy of saving national resources.
Description
Technical field
The utility model belongs to building material technical field, relates in particular to a kind of single-lock welt rectangular airduct.
Background technique
Dwelling house in the past is difficult to control to the quality of indoor air, and one all is the ventilation of windowing, and windows or does not window and all controlled by the owner.But this is subjected to the restriction of a lot of actual conditions, and such as too cold can not windowing in winter, summer, too hot can not windowing or do not windowed for peace and quiet in the holding chamber when having a rest yet, and caused guaranteeing the ventilation of windowing.Growing along with economy, the use of central air-conditioner more and more widely, but existing ventilation duct, exist easily get rusty, working life is short, inleakage is big shortcoming.
Summary of the invention
The purpose of this utility model is to propose a kind of single-lock welt rectangular airduct, solved the shortcoming that existing airduct easily gets rusty, the life-span is short, inleakage is big, it have occupy little space, comprehensively drop into low, operating cost is few, have good sealing property and stability characteristics.
To achieve these goals, the technological scheme that adopts is: a kind of single-lock welt rectangular airduct, be provided with airduct, feature is that the cross section of airduct is made as rectangular, airduct tube wall junction is made as single-lock welt and connects, described single-lock welt connects and comprises chimb down, last chimb, last undercut and following undercut, wind pipe wall joint, a left side is provided with protruding following chimb and last undercut downwards, right wind pipe wall joint is provided with chimb and following undercut, last undercut is inserted between chimb and the following undercut, following undercut is inserted in down between chimb and the last undercut, left wind pipe wall and the mutual interlock in right wind pipe wall joint, and sealability is much improved.
The utility model has the advantages that: adopt galvanized iron conduit, occupy little space, comprehensively drop into low, operating cost is few, characteristics with good sealing property and stability are no matter from economic benefit or from saving national energy strategy aspect, all are good developing direction.
Description of drawings
Fig. 1 is single-lock welt connection diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Embodiment, as shown in Figure 1, a kind of single-lock welt rectangular airduct, be provided with airduct, the airduct cross section is made as rectangular, airduct tube wall junction is made as single-lock welt and connects, described single-lock welt connects and comprises chimb 4 down, last chimb 1, last undercut 2 and following undercut 3, wind pipe wall 5 joints, a left side are provided with protruding following chimb 4 and last undercut 2 downwards, and right wind pipe wall 6 joints are provided with chimb 1 and following undercut 3, and last undercut 2 is inserted between chimb 1 and the following undercut 3, following undercut 3 is inserted in down between chimb 4 and the last undercut 2, left side wind pipe wall 5 and the mutual interlock in right wind pipe wall 6 joints, sealability is much improved, and has good sealing property and stability.Only being mounted to needs to go up undercut 2 and is inserted between chimb 1 and the following undercut 3, and following undercut 3 is inserted in down between chimb 4 and the last undercut 2 and gets final product, and the installation facility is convenient and practical.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, the apparent variation of being extended out thus or change still are among the protection domain of the present utility model.
