Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping connection structure, and more particularly, to a piping connection structure that allows piping to be easily connected without changing the structure of an object to be connected.
In order to connect various piping such as refrigerant piping and gas piping of an air conditioner to a predetermined mechanical device, a piping connection structure is required. The connection structure of these pipes should basically have to prevent leaks or leaks and should not be relaxed by vibration or external impact.
According to the connection structure of the conventional pipe, the end portion of the pipe is expanded like a fall pipe, and the nut and the bolt are tightened by fastening the pipe with the pipe in the middle, so that the pipe is tightly attached to the tip of the bolt to maintain airtightness. This is a method commonly used for aluminum pipes and copper pipes.
However, this method requires precise conditions by precisely aligning the shapes of the tip of the bolt and the expansion part of the pipe, and if the connection part is impacted and permanent shape deformation occurs, the possibility of leakage of the fluid becomes very large.
Although it has been proposed to connect pipes in a one-touch manner for easy connection of pipes (for example, Korean Patent Application Nos. 10-2008-0026226 and 10-2012-0111821) And the cost is increased due to the complexity.
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a piping connection structure capable of firmly securing airtightness or watertightness by adding a very simple component to a piping connection structure and eliminating problems caused by a loosened connection portion by impact . It is another object of the present invention to provide a piping connection structure that can easily carry out piping connection work by reducing the burden of processing an object to be connected to piping so as to exactly match the shape of the piping expansion portion .
The above objects are accomplished by providing a connecting body in which a bolt fastening portion is provided in a direction toward a pipe as an object to which a pipe is to be connected; Wherein the bolt fastening part is provided with a female screw fastened to the pipe before the end of the pipe is expanded and in a direction toward the connecting body, A fastening nut provided with an engagement jaw at an end point of the female screw; And an auxiliary connecting portion having a sealing portion provided at an end portion of the intubating portion and interposed between the inner circumferential surface of the extending portion and the bolt connecting portion, ; Wherein the sealing part is made of rubber or synthetic resin and is formed by a hollow pipe connection structure having one or more air pockets along the circumferential direction in the middle.
According to an aspect of the present invention, the sealing portion may be formed to have one side of the single pipe, and may be formed in the same shape as the pipe-expanding portion so as to cover the pipe-expanding portion of the pipe.
delete
According to another aspect of the present invention, the sealing portion is made of rubber or a synthetic resin material, and includes an inner tube which is inserted into the inner tube portion, an outer tube which is fitted to the outside of the intubation tube portion, It may be composed of a conical cylinder in the form of a widening toward the end.
According to the above-described structure, by further fitting the auxiliary connection between the piping and the connecting body in the existing piping connection structure, the shape of the connecting body can be freed from the burden of exactly matching with the extending portion of the piping, The airtightness and the watertightness can be firmly maintained. This makes it possible to easily carry out the connection work of the piping and provides an economical pipe connection structure with little cost.
