[0006] Furthermore, a spare sealing groove for combined connection is provided on the right end face of the second main connecting column.

[0007] Furthermore, the depth of the internal combined connecting groove is less than the length of the second main body connecting column.

[0008] Furthermore, a safety clearance groove is provided on each of the left and right sides of the internal combination clearance groove.

[0009] Furthermore, the outer edges of the internal combined connecting groove and the second fastening connecting threaded hole are provided with a chamfer structure for easy installation and assembly.

[0010] The beneficial effects of this utility model are:

[0011] This invention enables the simultaneous and secure connection of multiple splicing components of different sizes, ensuring better tightness of the combined position and making installation more convenient. It can replace multiple existing fastening accessories, resulting in higher efficiency in combination and more reliable connection security in later use. Its fastening position is tightly connected through the mutual cooperation of the inner and outer fastening structures at different positions, resulting in higher overall connection strength and meeting the combination requirements of connection positions with high strength requirements. At the same time, the internal structure can provide better protection against moisture and dust. Attached Figure Description

[0020] like Figures 1 to 7As shown, a gangway assembly fastening connector includes a conical first main connecting post 1 with its central axis pointing left and right. An integrally formed cylindrical second main connecting post 2 is located on the left side of the first main connecting post 1, forming the main structure of the connector. A conical combination clearance surface 3 is provided on the outer left side of the second main connecting post 2, providing better guidance during installation of the left-side structure and ensuring easier assembly. A first fastening threaded groove 4 is located on the right side of the outer cylindrical surface of the second main connecting post 2, and a second fastening threaded hole 5 is located at the center of the right side of the first main connecting post 1, enabling fastening connections of different sizes at two different locations. A cylindrical internal combination connecting groove 6 is located at the center of the left end face of the second main connecting post 2, allowing for installation and assembly with the staggered structure on the left side. A cylindrical combination sealing and stabilizing groove 7 is located on the right side of the internal combination connecting groove 6, which can cooperate with a sealing ring or sealing ring to improve internal sealing, increase internal space, and facilitate sealing operations. The right side of the internal combined connecting groove 6 is provided with an internal combined clearance groove 8 that communicates with the second fastening threaded hole 5, making the internal structure interconnected and facilitating installation. The diameter of the combined sealing and stabilizing groove 7 is larger than the diameter of the internal combined connecting groove 6, providing a reliable anti-loosening effect at the sealing mating position. During use, it can simultaneously and securely connect multiple splicing components of different sizes, ensuring better tightness at the assembly position, making installation easier, and replacing multiple existing fastening accessories. It offers higher efficiency in assembly connections and more reliable connection security in later use. Its fastening positions are tightly connected through the interlocking fastening structures on the inner and outer sides at different positions, resulting in higher overall connection strength and meeting the assembly requirements of connection positions with high strength requirements. Simultaneously, it provides better protection against moisture and dust for the internal mating structure.

[0021] Preferably, the right end face of the second main connecting column 2 is provided with a combination connection spare sealing groove. When the combination is performed, if this position is to be matched with other external components, the sealing stability of the matching position can be improved by the setting of this structure.

[0022] Preferably, the depth of the internal combined connecting groove 6 is less than the length of the second main body connecting column 2, which ensures higher overall strength of the main structure, better structural stability of the inner and outer sides, and stronger load-bearing capacity during use.

[0023] Preferably, the internal combination avoidance groove 8 is provided with a safety avoidance matching groove on each of its left and right sides. When the internal matching position is to be matched with auxiliary fastening components as needed, it can be matched with the avoidance, so that the internal combination position occupies less space and the matching operation is more convenient and safer.

[0024] Preferably, the outer edges of the internal combination connecting groove 6 and the second fastening connecting threaded hole 5 are provided with a chamfer structure for easy installation and assembly, which makes assembly and assembly more convenient, has a guiding function, and can improve the efficiency of assembly.

[0025] The above description is the preferred embodiment of this utility model.
