Detailed Description
As shown in fig. 1 to 7, a sealed location cooperation fastening connection spare, it adopts brand-new structural design, can satisfy two inside assembly connections of then cylindrical structure subassembly when assembling, and the cooperation sealing washer can ensure the connection leakproofness of inside and outside both sides, the stability of guarantee whole assembly combination is better, the security in later stage use is higher, the operation when this connecting piece is used and can be made whole assembly is easier, and the convenience when later stage is dismantled and is maintained is stronger, thereby the cost when maintaining has been reduced. It includes and is made and the center pin is cylindrical main part sealing connection stabilization column 1 of upper and lower direction by metal material, be equipped with integrated into one piece's cylindrical installation on the outer face of cylinder of main part sealing connection stabilization column 1 and end position cooperation spliced pole 2, can assemble the integrated configuration of outside position and end the position. The upper end center position of main part sealing connection stabilization column 1 is equipped with the cylindrical center combination assembly connecting hole 3 that runs through part lower extreme face, can cooperate the connection to the integrated configuration of inside. The inner cylindrical surface of the central combined assembly connecting hole 3 is provided with an integrally formed rectangular inner sealing matching positioning connecting column 4 which is uniformly distributed on the circumference, and the rectangular inner sealing matching positioning connecting column can be matched with a positioning hole in the inner sealing combined gasket for accurate matching, so that the stability of the inner sealing connection is better. The upper edge position and the lower edge position of the internal sealing matching positioning connecting column 4 are respectively provided with an internal assembly guiding matching fillet structure, so that the smoothness of the internal sealing washer is better when the internal sealing washer is matched and placed. The outer border position in upper and lower both ends of main part sealing connection stabilization column 1 with the installation is only equipped with safety protection assembly fillet 5 in the outer border position in upper and lower both ends of position cooperation spliced pole 2 respectively, makes holistic security higher, has avoided the existence of closed angle structure.
Preferably, the installation stop matching connection column 2 is located at the central position of the main body sealing connection stabilization column 1 in the vertical direction, so that the structure is better in strength and stronger in overall durability in use.
Preferably, the internal sealing matching positioning connection column 4 is located at the position of the main body sealing connection stabilization column 1 in the vertical direction, so that the stability of the whole structure can be further improved, and the service life of the whole structure is longer.
