[0020] like Figures 1 to 7As shown, a fire hose sealing assembly includes a cylindrical main sealing and mating column 1 with its central axis pointing left to right. The main sealing and mating column 1 is made of metal and can be made of commonly used materials in the prior art. On the right side of the main sealing and mating column 1, there is an integrally formed cylindrical sealing and stabilizing mating column 2 with the same central axis. During installation, this structure is inserted into the internal mating hole of the fire hose end structure. A cylindrical installation and assembly connecting groove 3 is provided at the center of the right end face of the sealing and stabilizing mating column 2, providing more space at this location. It can be used with a protruding positioning structure for stable mating as needed. This location can also be left unused. On the left side of the installation and assembly connecting groove 3, there is a cylindrical outlet mating connecting hole 4 that extends through the entire left side. This location serves as the outlet for later use. On the left side of the installation and assembly connecting groove 3, around the outer circumference of the outlet mating connecting hole 4, there is a ring of fastening assembly connecting holes 5, which allows for assembly with outlet accessories. The sealing and stabilizing mating column 2 has a V-shaped sealing and stabilizing mating groove 6 at the midpoint of its thickness in the left and right directions. This groove is used in conjunction with a rubber sealing ring, providing precise positioning and ensuring it won't fall out after mating. A circular sealing safety mating hole 7 is located on the left side of the sealing and stabilizing mating groove 6, penetrating the left side of the sealing and stabilizing mating column 2. This allows the mating rubber sealing ring to be pressed into this position, preventing rotation and ensuring better sealing stability. In use, it can be used as a transfer component to connect the fire hose end connector to the water nozzle. Its main function is reinforcement and sealing. The main structure features a dedicated sealing groove, and the sealing ring within this groove ensures precise and stable mating. After assembly, it ensures better overall sealing at the connection point, and the sealing ring will not shift, guaranteeing better durability during use. When installing and using it, it can be used as a sealing ring to fit between two components. The rubber sealing ring can be precisely placed in the sealing and stabilizing groove on the assembly, and the overall fit can ensure a more reliable sealing safety at the connection point.

[0021] Preferably, the right edge of the sealing safety mating hole 7 is provided with a convenient chamfer structure for mating guidance. When mating, the rubber sealing ring placed at this position can be pressed into this position more smoothly, making the assembly operation more convenient and further improving the sealing stability.

[0022] Preferably, the sealing and stabilizing groove 6 is located at the center of the thickness of the sealing and stabilizing column 2 in the left and right directions, which makes the structure at this position more stable and ensures higher overall structural strength.

[0023] Preferably, the right end face of the sealing and stabilizing mating column 2 is provided with a spare sealing combination groove. As needed, a rubber sealing ring can be used in this position for sealing combination during mating, which can realize the sealing connection of the right mating position and meet the usage requirements of application environments with higher sealing requirements.

[0024] Preferably, the left edge of the main sealing column 1 is provided with a chamfer structure for easy installation and assembly, which makes assembly easier and has a guiding function, thereby improving the efficiency of assembly.

[0025] 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.
