Description

Description: TECHNICAL FIELD The present invention relates to a fixture for connecting a duct to be used for air conditioning.

2. Description of the Related Art Conventionally, a main body of an air conditioner is connected to a blowout unit facing each room by a duct. This connection is, for example, as shown in FIG.
An adapter 2 previously fixed to the main body 1 is provided. A duct 3 made of a heat insulating material is inserted into the adapter 2 from outside, and a fixing band 4 is firmly attached to a portion corresponding to the periphery of the adapter 2. After fixing, the heat insulating material 5 was further wrapped around the fixing band 4, and the covering tape 6 was wrapped to connect the duct 3.

SUMMARY OF THE INVENTION In such a conventional configuration, when connecting the main body 1 and the duct 3 to the adapter 2, the fixing band is supported while the long duct 3 is supported by hand with the duct 3 inserted into the adapter 2. 4 and wrap the heat insulating material 5 and then fix it with the tape 6 and these parts must be prepared. Especially in the case of the recessed ceiling type, the inside of the ceiling may be narrow. Therefore, it was particularly difficult and had complicated construction problems.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a duct fixing device that does not require complicated construction and parts.

Means for Solving the Problems In order to solve this problem, the present invention comprises an adapter fixed to a main body, and a resin connection tube attached to the adapter, wherein the connection tube is provided at an outer periphery of the adapter. It is composed of an inner cylinder and an outer cylinder forming a double layer consisting of an inner jacket and an outer jacket, and a slit is provided in the inner jacket of the outer cylinder, and a bag portion is provided at a tip of the outer cylinder, A fixing band is mounted in the bag portion, the fixing band is led out from a hole of the outer cylinder, a duct is inserted into an air conditioning unit between the inner cylinder and the outer cylinder, and tightened with the fixing band. The fixing resin is used as the fixing resin.

Operation With this configuration, the connection tube is attached to the adapter in advance, and the duct is inserted into the air-conditioning unit between the inner tube and the outer tube of the connection tube, and is fixed when the duct comes into contact with the bottom of the air-conditioner. The band is tightened, and the slit provided in the inner jacket connects the duct tightened by elasticity.

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

On the other hand, a connection tube 13 made of resin is attached to the outer periphery of the adapter 11 in advance. The connection tube 13 has an inner tube 14 fitted on the outer periphery of the adapter 11, and an outer tube 17 on the outside having a cavity 16 into which the duct 15 can be inserted, and the inner tube 14 and the outer tube 17 Are integrated over the bottom 18. The outer cylinder 17 has an inner jacket 19a over the entire circumference.
And a jacket 19b, and a front end portion 20 of the outer cylindrical body 17 forms a bag portion 21 slightly projecting inward. A fixing band 22 is mounted in the bag portion 21 in advance, and a tip end 24 of the fixing band 22 is led out of a hole of the jacket 19b. Further, the inner cover 19a of the outer cylindrical body 17 is provided with several slits 26 around the inner cover 19a so that a fixed band is formed.
When the duct 15 is tightened at 22, the duct 15 has elasticity so that it is tightened.

In the above configuration, although not necessarily inside the ceiling or the like, if the main body 10 and the duct 15 are to be connected inside the ceiling or the like, the connection cylinder is fixed to the adapter 11 fixed to one side of the main body 10 in advance. 13 is fitted to the outside of the adapter 11, and the fitting
The connection tube 13 is locked at the position 12a, and the connection tube 13 is fixed. Next, push the duct 15 into the hollow portion 16 and insert it until it contacts the bottom portion 18.
By pulling the duct 24, the duct 15 is tightened from the outer periphery by the elasticity of the slit 26, and the fixing and connection of the duct are completed.

Only by tightening with the fixing band 22, the fixing of the duct 15 and the dew condensation of the connection tube 13 made of resin can be prevented, and the connection tube 13 is also beautiful.

Effect of the Invention As is clear from the description of the above embodiment, the present invention attaches a connecting tube to the outside of the adapter in advance, and this connecting tube is made up of an inner tube, an outer cover, and an inner cover provided with a slit. Since the fixing band is attached to the bag at the tip of the outer cylinder, a hollow portion between the inner cylinder and the outer cylinder when the duct is connected to the adapter. Can be connected by simply inserting the duct into the bottom until it abuts on the bottom and fixing it with a fixed band.Connection of the duct becomes extremely easy, and the connection tube also provides a heat insulating effect. In addition, there is an effect that finishing with a heat insulating material or tape is unnecessary, and the finishing can be beautifully performed.
