A pipe body portion comprising a first pipe body having a first screw thread formed on an outer surface, and a second pipe body extending to one side from the first pipe body; A cover portion having a second screw thread formed on the inner surface that screws into the first screw thread; A ball pipe portion coupled to be rotatable at a set angle inside the above pipe body portion; and A flange portion disposed between the pipe body portion and the ball pipe portion, and which eliminates the gap between the ball pipe portion and the pipe body portion; is included. The above ball pipe section includes a ball pipe head having a predetermined radius of curvature, and A pipe connection device characterized in that the above flange portion is coupled to the ball pipe head to satisfy the following mathematical formula. [Mathematical Formula 1] θ ≤ 5° (In Equation 1, θ represents the angle formed by the straight line connecting the point of contact between the flange portion and the ball pipe head and the center of the sphere defined at the ball pipe head, and the plane defined in the vertical direction from the center of the sphere of the ball pipe head.)
In Article 1, A pipe connection device characterized by the above angle θ being 0 degrees.
In Article 1, A pipe connection device characterized in that the above-mentioned ball pipe section further includes a ball pipe body extending in one direction from the ball pipe head.
In Paragraph 3, A pipe connection device characterized in that the above-mentioned ball pipe section further includes a ball pipe body protrusion formed to be bent and extended to one side from the ball pipe body.
In Paragraph 4, A pipe connection device further comprising: an auxiliary cover part that is coupled to the protrusion of the ball pipe body and screw-coupled to the pipe part.
In Paragraph 4, A pipe connection device characterized by the above auxiliary cover portion including an auxiliary cover body portion having a fourth screw thread formed on its inner surface, and an auxiliary cover catch portion that is formed to extend and bend to one side from the auxiliary cover body portion and contacts and connects with the protrusion of the ball pipe body.
In Paragraph 4, A pipe connection device characterized in that the above-mentioned ball pipe body includes a first ball pipe body extending parallel to the ball pipe head and a second ball pipe body formed at an angle in the first ball pipe section.
In Article 1, A pipe connection device characterized by comprising: a cover body portion having the second screw thread formed on its inner surface; and a cover catch portion that is extended and bent to one side from the cover body portion and contacts the ball pipe portion.
In Article 8, A pipe connection device characterized in that the contact surface of the cover catch portion with the ball pipe portion is formed in a shape corresponding to the outer surface of the ball pipe head.
In Article 1, A pipe connection device characterized in that the inner surface of the flange portion is formed in a shape corresponding to the outer surface of the ball pipe head.
In Article 1, The above pipe body further includes an inclined body formed at an angle in the first pipe body, and a pipe connecting body connecting the inclined body and the second pipe body. A pipe connection device characterized in that the outer surface of the flange portion is formed to be inclined so as to correspond to the inner surface of the inclined body.
In Article 1, A pipe connection device characterized in that the second pipe body has a third screw thread formed on its outer side.

Description

Pipe connection device The present disclosure relates to a pipe connecting device. Generally, piping refers to the installation of pipes for water supply, drainage, hot water supply, cooling, heating, and gas construction, or the pipes themselves. It connects equipment placed at various locations to provide a passage for fluids to pass through, and materials such as cast iron pipes, steel pipes (Hook gas pipes), galvanized steel pipes (Back gas pipes), and copper pipes are primarily used. However, conventional piping not only presents difficulties in interconnection but also carries a high risk of leakage at the connected sections. Therefore, there is a need to improve this. Furthermore, regarding piping, there is a need for a pipe connection device with a specified range of motion to allow layout changes without placing a load on the pipes when the layout is altered according to the pipe arrangement. In addition, a function that prevents leakage while maintaining such a range of motion is also required. FIG. 1 is a drawing showing a pipe connection device according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view of a pipe connection device according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view of a pipe connection device according to the first embodiment of the present invention. FIG. 4 is a drawing illustrating the cross-sectional structure of a pipe connection device according to the first embodiment of the present invention. FIG. 5 is a drawing illustrating the cross-sectional structure of a pipe connection device according to a second embodiment of the present invention. FIG. 6 is a cross-sectional view illustrating the operating range of a pipe connection device according to the first embodiment of the present invention. Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the attached drawings. The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the attached drawings. However, the technical concept of the present disclosure is not limited to the following embodiments but can be implemented in various different forms. The following embodiments are provided merely to complete the technical concept of the present disclosure and to fully inform those skilled in the art of the scope of the present disclosure, and the technical concept of the present disclosure is defined only by the scope of the claims. It should be noted that when assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present disclosure, if it is determined that a detailed description of related known components or functions could obscure the essence of the present disclosure, such detailed description is omitted. Unless otherwise defined, all terms used herein (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which this disclosure pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise. The terms used herein are for describing the embodiments and are not intended to limit this disclosure. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. Additionally, terms such as first, second, A, B, (a), (b), etc., may be used to describe the components of the present disclosure. These terms are intended only to distinguish the components from other components and do not limit the nature, order, or sequence of the components. Where it is stated that a component is "connected," "coupled," or "joined" to another component, it should be understood that the component may be directly connected or joined to the other component, but that another component may also be "connected," "coupled," or "joined" between each component. As used in this disclosure, "comprises" and/or "comprising" do not exclude the presence or addition of one or more other components, steps, actions, and/or elements to the mentioned components, steps, actions, and/or elements.
