[0019] like Figures 1 to 7As shown, a fire-fighting equipment sealing ring includes a cylindrical main body sealing matching column 1 with a central axis in the left-right direction and made of rubber material, an integral cylindrical transition sealing stabilizing column 2 is provided on the right side of the main body sealing matching column 1, and an integral cylindrical sealing connection safety column 3 is provided on the right side of the transition sealing stabilizing column 2, which can achieve a matching effect of double sealing at different positions when connected. It is characterized in that: the diameter of the transition sealing stabilizing column 2 is smaller than the diameter of the sealing connection safety column 3, and the diameter of the sealing connection safety column 3 is smaller than the diameter of the main body sealing matching column 1, so that the space at the middle position is larger and other structures can be set. A cylindrical center matching connection hole 4 that runs through the right side of the main body sealing matching column 1 is provided at the center position of the left end face, which can match the matching column of the center combination to be set together. A conical combination stabilizing guide groove 5 is provided at the right edge position of the center matching connection hole 4, so that the matching installation operation at the center position is more convenient. The outer cylindrical surface of the transition sealing stabilizing column 2 is provided with an integrally formed cylindrical sealing buffer fitting column 6 that is evenly distributed around the circumference. The central axis of the sealing buffer fitting column 6 is perpendicular to the central axis of the main sealing fitting column 1. The diameter of the sealing buffer fitting column 6 is the same as the length of the transition sealing stabilizing column 2. The left-right projection of the sealing buffer fitting column 6 exceeds the left-right projection area of the sealing connection safety column 3. The left-right projection of the sealing buffer fitting column 6 does not exceed the left-right projection area of the main sealing fitting column 1, ensuring that the middle position has better strength when fitting, and can have a more precise extrusion fit when fitting, so that the sealing on both sides of the middle position is more reliable. When heated, the middle position can also have a better sealing deformation space, so that the sealing safety of the connection position is more reliable, ensuring the stability of the sealing of the fire-fighting equipment connection position. It adopts a new structural design. By setting a sealing matching column perpendicular to the main axis in the middle position of the main structure, the middle position can form a staggered extrusion matching sealing effect when tightly matched. It has a reliable buffering sealing effect, and the connection position can form a double sealing effect. When heated during use, the tightness between each other will become better and better, thereby ensuring a higher sealing safety at the matching position and making the fire-fighting equipment safer and more stable during use.
[0020] In order to improve the reliability of the overall structure during use, a boss structure that exceeds the sealing buffer fitting column 6 can be set on the right side of the main body sealing fitting column 1. This can prevent the sealing buffer fitting column 6 from being squeezed and deformed outward when tightly fitted, making the internal sealing safety more reliable.
[0021] Preferably, the thickness of the main body sealing matching column 1 is greater than the thickness of the sealing connection safety column 3, and the thickness of the main body sealing matching column 1 is less than the thickness of the transition sealing stability column 2, so that the overall structural support strength is better and the service life during use is longer.
[0022] Preferably, a combined avoidance chamfer structure is provided at the right edge of the sealing buffer fitting column 6, so that the combined operation during the fitting connection is more convenient.
[0023] Preferably, two adjacent sealing buffer mating columns 6 are not tightly connected together, so that a certain gap can be formed between them. When tightening, there is a certain extrusion space to ensure that the connection operation during mating is easier.
[0024] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
