Abstract
The utility model provides a double-inserter interface for a ventilating duct, comprising two outer jack assemblies, two inner jack assemblies, inner inserters and outer inserters, wherein, the inner inserters and outer inserters can wrap into four frames; the inner inserters are inserted into slots of the inner jack assemblies and fixed in a riveting mode; the outer inserters are inserted into slots of the outer jack assemblies and fixed in a riveting mode The utility model has the advantages that the double-inserter interface can be suitable for medium and high pressure ventilation duct systems, the connection strength of the interface is improved, and sealing performance is good.
Description
The utility model relates in a kind of central air conditioning equipment the jockey of the ventilation duct port of transmission usefulness, and what especially relate to the ventilation duct port can't blue jockey.
The ventilation shaft of transmission usefulness in the central air conditioning equipment, the connection between the tube and tube have adopted now and can't bluely connect, and can save steel like this, alleviate the weight of ventilation duct system.At present, the domestic structures that adopt list cutting connection to add the fluid sealant bar more, its shortcoming is: only be suitable for idling slow speed system, wind speed is less than 10m/s in the pipe, and blast is less than 500Pa; Single bonding strength of transplanting a cutting is relatively poor, single connection aluminium matter or plastics of adopting of transplanting a cutting are transplanted a cutting more, be subjected to the restriction of connection space, size, and the restriction of self intensity, it is thiner that the junction seems, connect the back airduct in axial tension with radially under the effect of shear stress, corresponding attenuating is prone to phenomenons such as interface damages, leaks out to the intensity of its interface with growth service life.
The purpose of this utility model be overcome above-mentioned technology not enough, provide a kind of novel ventilation shaft two interfaces of transplanting a cutting, with solve intensity, leak out, problem such as sealing, and applicable to middle and high pressure ventilation pipe system.
The technical solution of the utility model is such, designs the two interfaces of transplanting a cutting of a kind of ventilation shaft, and it comprises: two external socket assemblies, two interior socket assemblies, the interior cutting that can surround four frames and outer cutting; Be provided with the slot that turns up around the described external socket assembly, and be fixed in the external port of ventilation duct respectively; Be provided with the slot that turns up around the socket assembly in described, and be fixed in the inner port of ventilation duct respectively; Riveted and fixed behind the slot of socket assembly in interior cutting is inserted, riveted and fixed behind the slot of outer cutting insertion external socket assembly.
The two interfaces of transplanting a cutting of ventilation shaft of the present utility model have the following advantages:
1, applied widely; Not only can be used as low-pressure system (blast is less than 500Pa), and be applicable to middle and high pressure ventilation pipe system, wind speed is greater than more than the 10m/s, and blast is between 1500-2000Pa.
2, strengthen the interface bonding strength; Inside and outside two the cutting do not connect, and strengthened joint strength, and be fragile, leak out.
3, increase sealing; Inside and outside connect respectively, fixing, and do permanent fixing in the junction.Inject foam filled dose and foam rapidly in the slit, fill up the slit, it is in aggregates that two pipes are connected, and solidifies the back inleakage near null value.
Below in conjunction with drawings and Examples, further specify the technical solution of the utility model.
Fig. 1 is the structural representation after two ventilation ducts connect;
Fig. 2 is two ventilation duct junction decomposition texture schematic diagrames.
Fig. 1 and Fig. 2 illustrate the structure at two ventilation duct interface places of the present utility model.See figures.1.and.2, this junction structure comprises: two external socket assemblies 1, two interior socket assemblies 4, can surround the interior cutting 3 of four frames and transplant a cutting 4 outward; Be provided with the slot 11 that turns up around the external socket assembly 1, and be fixed in the external port place of ventilation duct 6 respectively; Be provided with the slot 41 that turns up around the interior socket assembly 4, and be fixed in the inner port place of ventilation duct 6 respectively; In transplant a cutting 3 insert in behind the slot 41 of socket assembly 4, with pulling rivet 9 riveted and fixed, transplant a cutting 2 slot 11 backs of inserting external socket assemblies 1 outward with rivet 9 riveted and fixed.And persist suitable opening at any relative angle, inject as calculated filling-foam agent from opening part to connecting the slit.The filling-foam agent of injecting is foamed rapidly in the slit, fills up the slit, and making two pipes bonding is an integral body, after the curing, makes the airduct inleakage near null value.
In the such scheme, interior socket assembly 4, external socket assembly 1 or interior cutting 3, transplant a cutting and 4 adopt galvanized iron sheets to make its intensity height and more economical practicality outward.
Claims (2)
1, the two interfaces of transplanting a cutting of a kind of ventilation shaft is characterized in that it comprises: two external socket assemblies, two interior socket assemblies, the interior cutting that can surround four frames and outer cutting; Be provided with the slot that turns up around the described external socket assembly, and be fixed in the external port of ventilation duct respectively; Be provided with the slot that turns up around the socket assembly in described, and be fixed in the inner port of ventilation duct respectively; Riveted and fixed behind the slot of socket assembly in interior cutting is inserted, riveted and fixed behind the slot of outer cutting insertion external socket assembly.
2, the two interfaces of transplanting a cutting of ventilation shaft according to claim 1 is characterized in that the making of described inside and outside socket assembly or inside and outside cutting employing galvanized iron sheet.
