Description

Technical Field

[0001] This utility model relates to the field of pipeline assembly and connection technology, and in particular to a pipeline sealing connection structure. Background Technology

[0002] When installing pipelines, different pipelines are usually connected by pipe fittings. The sealing of the fittings usually requires the use of sealing rings. Existing fitting components have a fixed sealing position during installation, and the tightness of the sealing fit cannot be adjusted during the tightening process. This makes the tightening operation difficult. If the dimensional tightness is too small, it will affect the installation efficiency. If the dimensional tolerance is too large, it will be difficult to meet the pressure resistance requirements for sealing, and the durability during use will also be relatively poor. Utility Model Content

[0003] The purpose of this utility model is to provide a pipe sealing connection structure. It adopts a completely new structural design, allowing for combination with the two ends of the connector components at the pipe mating positions. During use, it can be fastened together with a sealing ring. Through the circumferentially arranged, staggered sealing combination stabilizing grooves, there is a certain deformation space during installation and fastening. Furthermore, during fastening, the sealing ring can be pressed into the sealing combination stabilizing grooves, resulting in better overall sealing stability and higher installation efficiency. This avoids assembly difficulties caused by small dimensional tolerances, effectively improving assembly efficiency, ensuring sealing safety during assembly, and enhancing the durability and service life of the mating positions in later use.

[0004] The technical solution of this utility model is as follows:

[0005] A pipe sealing connection structure, characterized in that: it includes a cylindrical first main body mating column; a conical second main body mating column with the same central axis is provided on the right side of the first main body mating column; a cylindrical combined stop mating groove is provided at the center of the left end face of the first main body mating column; a cylindrical main body mating placement hole penetrating the right side of the combined stop mating groove is provided on the right side of the combined stop mating groove; a first sealing combined stabilizing groove is provided on the left side of the first main body mating column, evenly distributed around its circumference; the inner side of the first sealing combined stabilizing groove communicates with the main body mating placement hole; the outer side of the first sealing combined stabilizing groove completely penetrates the outer surfaces of the second main body mating column and the first main body mating column; the depth of the first sealing combined stabilizing groove is greater than the length of the first main body mating column; a second sealing combined stabilizing groove is provided on the right side of the second main body mating column, located between two adjacent first sealing combined stabilizing grooves; the inner side of the second sealing combined stabilizing groove communicates with the main body mating placement hole; the outer side of the second sealing combined stabilizing groove completely penetrates the outer surfaces of the second main body mating column and the first main body mating column; the depth of the second sealing combined stabilizing groove is greater than the length of the second main body mating column.

[0006] Furthermore, the second sealing assembly stabilizing groove is also connected to the assembly stop fitting groove.

[0007] Furthermore, the left end face of the second main body mating post has the same dimensions as the right end face of the first main body mating post.

[0008] Furthermore, the outer edges of the combined stop groove and the main body fitting hole are provided with a guide rounded corner structure to facilitate fitting.

[0009] The beneficial effects of this utility model are:

[0010] This utility model adopts a brand-new structural design. During use, it can be combined with the two ends of the connector component to fit the pipe. It can be fastened together with a sealing ring. The staggered sealing combination stabilizing grooves arranged circumferentially provide a certain deformation space during installation and fastening. During fastening, the sealing ring is pressed into the sealing combination stabilizing groove, resulting in better overall sealing stability and higher installation efficiency. This avoids assembly difficulties caused by small dimensional tolerances, effectively improving assembly efficiency and ensuring sealing safety during assembly. Furthermore, the mating positions are more durable and have a longer service life. Attached Figure Description

[0018] like Figures 1 to 6As shown, a pipe sealing connection structure includes a cylindrical first main body mating column 1. A conical second main body mating column 2 with the same central axis is located on the right side of the first main body mating column 1. A cylindrical combined stop mating groove 3 is located at the center of the left end face of the first main body mating column 1, which provides end-positioning mating with the first pipe during installation, improving connection stability. A cylindrical main body mating placement hole 4 penetrating the right side of the combined stop mating groove 3 is located on the right side, allowing it to mate with the interior of the joint structure, ensuring more internal space during use. A first sealing combined stabilizing groove 5 is circumferentially distributed on the left side of the first main body mating column 1. The inner side of the first sealing combined stabilizing groove 5 communicates with the main body mating placement hole 4, and the outer side of the first sealing combined stabilizing groove 5 completely penetrates the outer surfaces of the second main body mating column 2 and the first main body mating column 1. During installation, a mating sealing ring can be fitted inside, and during tightening, a clamping fit with the joint structure achieves a tight assembly of the connection structure, ensuring better overall tightness of the sealing mating position and making the connection operation more convenient. The depth of the first sealing combination stabilizing groove 5 is greater than the length of the first main body mating post 1. The second main body mating post 2 is provided with a second sealing combination stabilizing groove 6 on the right side between two adjacent first sealing combination stabilizing grooves 5. The inner side of the second sealing combination stabilizing groove 6 communicates with the main body mating placement hole 4. The outer side of the second sealing combination stabilizing groove 6 completely penetrates the outer side of the second main body mating post 2 and the outer side of the first main body mating post 1. The depth of the second sealing combination stabilizing groove 6 is greater than the length of the second main body mating post 2, which makes the deformation space of the overall structure larger, the combination insertion operation during mating is easier, and the overall mating connection efficiency is higher. It adopts a brand-new structural design, which can be combined with the two ends of the connector components to fit the pipe. During use, it can be fastened with a sealing ring. Through the circumferentially set staggered sealing combination stabilizing grooves, there is a certain deformation space during installation and fastening. When tightening, the sealing ring can be pressed into the sealing combination stabilizing groove, which improves the overall sealing stability and the fitting efficiency during installation. It also avoids the situation where small dimensional tolerances cause assembly difficulties, effectively improves the efficiency of assembly, ensures the sealing safety during assembly, and enhances the durability of the mating position in later use, resulting in a longer service life.

[0019] Preferably, the second sealing combination stabilizing groove 6 is also connected to the combination stop fitting groove 3, so that the deformation fit range during combination is larger and the fitting connection operation is more convenient.

[0020] Preferably, the left end face of the second main body mating column 2 is exactly the same size as the right end face of the first main body mating column 1, which makes the structural strength of the connection position higher and can further improve the overall structural strength.

[0021] Preferably, the outer edges of the combined stop groove 3 and the main body fitting hole 4 are provided with a guide rounded corner structure to facilitate fitting. This makes the insertion and placement operation when fitting with the pipe more convenient during assembly, improves the smoothness of fitting, and avoids damage to the pipe surface.

[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
