Abstract

PURPOSE:To provide a duct fixing device not requiring any troublesome work and parts by a method wherein a connecting cylinder is fixed to an adapter, a duct is inserted into a clearance between an inner cylinder and an outer cylinder of the connecting cylinder, fastened by fixing screws at a flange part where the duct abuts against a bottom part in the clearance and the duct is connected by the split outer cylinder. CONSTITUTION:When a main body 10 and a duct 15 are maintained, a connecting cylinder 13 is fitted to an outside part of an adapter 11 fixed to one side surface of the main body 10. This fitting is carried out such that an extreme end of an inner cylinder 14 is engaged with a projection 12a of the adapter 11 and then the connecting cylinder 13 becomes fixed state. Then, the duct 15 is pushed into a clearance 16 and inserted until it is abutted against a bottom part 18, thereafter it is fastened from an outer circumference with fixing screws 21 only by a size of a slit 26, resulting in that the duct 15 can be connected. In this way, as the duct is fastened by the fixing screws 21, then it is hermetically sealed by a tape 19, an outside area of the duct 15 is wound around by a thermal insulation material 25, a protection metallic net 29 is wound around them to finish the coupling work, resulting in that an easy, clear and esthetic finished state can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fixture for connecting ducts used for air conditioning.

Conventional technology Conventionally, a duct is used to connect the main body of an air conditioner such as a ceiling-embedded type to a blow-off unit facing the indoor side. There is a main body 1 of an embedded type air conditioner, and an adapter 2 is provided on the main body 1 in advance and has a protrusion 2a formed over the entire circumference to prevent removal.
Insert the metal duct 3 from the outside, make several fixing holes in the area corresponding to the periphery of the adapter, fix it with the tapping screws 4, wrap the sealing tape 5, and then wrap the heat insulating material 6. The protective wire mesh 7 was then wrapped around it to complete the connection work.

Problems to be Solved by the Invention In such a conventional configuration, when connecting the main body 1 and the duct 3 to the adapter 2, with the duct 3 inserted into the adapter 2, the long duct 3 is supported by hand while the fixing hole is inserted. This requires complicated work such as opening the hole, fixing it with screws 4, wrapping it with tape 5, wrapping it with insulation material 6, and protecting it with a protective wire mesh 7. Especially in the case of a ceiling-mounted type, Because the inside of the attic is narrow, connection construction is especially difficult, and the construction is complicated.

The present invention solves the above-mentioned conventional problems, and aims to provide a duct fixing device that does not require complicated construction or parts.

Means for Solving the Problems In order to solve this problem, the present invention includes an adapter fixed to a main body, and a metal connecting tube attached to the adapter, and the connecting tube is connected to the adapter. It is composed of an inner cylinder that is fitted into the outer periphery and an outer cylinder that is integral with the double layer. Prepare,
A fixing screw is attached to the flange, a duct is inserted into the air conditioning section between the inner cylinder body and the outer cylinder body, and the fixing screw is tightened to fix the fixing metal fitting. This is what I did.

Effect With this configuration, the connecting tube is attached to the adapter in advance, the duct is inserted into the gap between the inner tube and the outer tube of the connecting tube, and when the duct comes into contact with the bottom of this gap, the flange is removed. The ducts are connected by the divided outer cylindrical body by tightening the fixing screws in the section.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, an adapter 11 is fixed in advance to one side of a main body 10 of the air conditioner, and this adapter 11 is provided with a slight protrusion 12a over the entire outer periphery to prevent removal.

On the other hand, a cylindrical connecting tube 13 made of metal is attached to the outer periphery of the adapter 11 in advance. The connection tube 13 is the adapter 11
an inner cylinder body 14 that fits around the outer circumference of the cylinder, and an outer cylinder body 17 on the outside having a gap 16 into which the duct 15 can be inserted; It has become. The outer cylindrical body 17 is partially divided into two parts by a slit 26 at the top and bottom, and a collar part 20 is formed at the top and bottom at the tip of the outer cylindrical body 17, and fixing screws 21 are installed at two places on both sides. It is set up.

In the above configuration, although it is not limited to the ceiling,
When connecting the main body 10 and the duct 15 inside the attic, etc., connect the adapter 11 fixed to one side of the main body 10.
The connecting tube 13 is fitted onto the outside of the adapter 11 in advance. In this fitting, the tip of the inner cylinder 14 is
It comes to be locked by the protrusion 12a of the adapter 11, and the connecting tube 13 is in a fixed state. Next, the duct 15 is pushed into the gap 16 until it contacts the bottom 18, and then the fixing screw 21 is tightened from the outer periphery by the size of the slit 26, and the duct 15 can no longer be connected. When the fixing screws 21 are tightened in this manner, the duct 15 is sealed with tape 19, the outside of the duct 15 is wrapped with the heat insulating material 25, and the protective wire mesh 29 is further wrapped to finish the duct 15, resulting in a simple and beautiful finish.

Effects of the Invention As is clear from the description of the above embodiments, in the present invention, a connecting tube is attached to the outside of the adapter in advance, and this connecting tube is composed of an inner gI cylinder and an outer cylinder provided with a slit. Since the duct is tightened with a fixing screw on the flange at the tip of the outer cylindrical body, when connecting the duct to the adapter, insert the duct into the gap between the inner cylindrical body and the outer cylindrical body at the bottom. Connection can be made by simply inserting it until it makes contact and fixing it with a fixing screw, eliminating the difficulty of drilling screw holes in the duct, making it extremely easy to connect the duct, and wrapping it with tape, insulation material, and protective wire mesh. It also has the effect of being extremely easy to do.
