Abstract

The utility model relates to a spigot-and-socket jointing device for a blast pipe, belonging to the technical field of the blast pipe. The utility model is composed of four corner refractory protecting corners, two refractory transverse protecting boards and two refractory vertical protecting boards, and an integral type and a fission type can be arranged between each protecting corner and each protecting board and can be made of refractory materials with certain intensity. A plurality of self tapping reinforcing screw holes are arranged on each protecting corner and each protecting board. The utility model has the advantages of convenient fabrication, resistant corrosion, long service life, low cost, convenient installation and stable and reliable quality and is refractory. When the blast pipe is connected and is used, the utility model has small architectural space, and connecting tightness is good. The utility model has the advantages of less system air leakage, less power consumption, orderly and beautiful blast pipe system, etc.

Description

The spigot and socket type wind tube connecting device

The utility model relates to a kind of airduct socket joint connection set, belongs to the airduct technical field.

The traditional flange connection of the many employings of the connection of present domestic air conditioner airduct, this method is made simple, easy for installation, but the defective that has two aspects: the one, flange body itself is given prominence to airduct body 30-50mm, last lower flange takies effective headroom and reaches 60-120mm, causes the huge waste of construction investment; The 2nd, flange connections is tight inadequately, and inleakage is bigger, and system's operation energy consumption is big.

In recent years, both at home and abroad some special connection sets have appearred in the airduct product, have reduced building and having taken up room and the airduct inleakage, but all had link and Placement complexity, make defectives such as using inconvenience.Key Placement as domestic appearance, adopt plastics or aluminum alloy to be processed into special section bar, then section bar is riveted on airduct two end connectors, during connection two sections airduct ports are close together, insert along the section bar preformed groove with special I keyboard again, two sections airducts are socketed together, seal with glue then: also there are fabricated metals corrosion and plastic article problem such as do not prevent fires in its fabrication and installation complexity, cost height.

The purpose of this utility model is to overcome the defective that traditional airduct link exists, provide a kind of take space little, can reduce the airduct inleakage, make easy to use and reliable spigot and socket type wind tube connecting device.

The technical solution of the utility model is: the spigot and socket type wind tube connecting device is made up of the fire-resistant horizontal backplate of four fire-resistant corner protectors 1 of dihedral and two 2, two fire-resistant perpendicular backplates 3, can be integrated type, split type between each corner protector, the backplate, available various refractory materials (can be common refractories such as FRIM, calcium silicate, gypsum, aluminum alloy) with certain intensity are made; Also can be provided with a plurality of self tappings on each corner protector, the backplate and reinforce screw hole 4 (be convenient to self tapping and reinforce screw).

Fig. 1 is the utility model schematic representation,

Fig. 2 is 5 for the airduct section among the utility model user mode schematic representation, the figure.

Further set forth embodiment of the present utility model below in conjunction with accompanying drawing: as shown in Figure 1, 2, this spigot and socket type wind tube connecting device is made up of the horizontal backplate of four FRIM dihedral corner protectors 1 and two FRIM 2, two perpendicular backplates 3 of FRIM, evenly be provided with two row's self tappings on each corner protector, the backplate and reinforce screw hole 4, be integrated type (the split type undetermined situation of airduct size that is applicable to) between corner protector and backplate.

During use, can determine to select for use split type or integrated type socket joint connection set according to the situation of airduct in the concrete engineering.For the airduct of standard (fixing) size, can select the integrated type connection set that matches with it for use.For the airduct that off-standard size must be determined at the scene, can select split type connection set for use, according to the concrete size of airduct, determine the size of horizontal, vertical backplate.When installing and using, the interior table and the airduct section connection mouth (port) of socket joint connection set are located outer wall brushwork adhesive (can be common adhesive such as silicon sealant, contact glue), then the socket joint connection set is inserted the termination (connection mouth) of two sections airducts that must connect, the termination of two sections airducts is compressed the connection that can finish airduct easily mutually: for preventing to move, also available self tapping screw is reinforced screw hole by self tapping and is fixed.

The utility model is owing to adopt simple socket joint linkage structure and refractory material to make, solved the conventional flange Placement big deficiency that takes up room, under identical airduct size condition, can save the space of 50-100mm, can make the construction level height reduce 50-10mm, save construction investment greatly, the socket joint running-on encases the seam of the connection between airduct tightly, air-line system is leaked out significantly reduce, thereby have the following advantages:

1, making is simple, production cost is low, easy for installation, steady quality is reliable:

2, airduct connect to use this device take space few, connect good leak tightness, few, the less energy consumption of system air leakage amount:

3, air-line system neat appearance:

4, the socket joint connection set only links together two sections airduct ports tightly in the airduct outside, does not have the water of condensation problem.

5, fire-resistant anti-corrosion, long service life.

Claims

1, a kind of spigot and socket type wind tube connecting device is characterized in that it is made up of four fire-resistant corner protectors of dihedral (1) and two fire-resistant horizontal backplates (2), two fire-resistant perpendicular backplates (3), can be integrated type or split type between each corner protector, the backplate.

2, spigot and socket type wind tube connecting device according to claim 1 is characterized in that also can being provided with on each corner protector, the backplate a plurality of self tappings and reinforces screw hole (4).
