Description

Integrated atmospheric plug for racing boat Technical Field The application relates to the technical field of racing boats, in particular to an integrated air plug for a racing boat. Background When the racing boat is designed, the special application scene is considered, the lightweight design is generally carried out, meanwhile, the requirements on structural strength and safety are also met, and a hard shell double-layer hull structure is generally adopted. When the racing boat is sunned on the shore, the internal air pressure of the boat body is higher than the external air pressure due to direct sunlight, so that the shell is cracked, and the integrity of the boat body structure is seriously affected. To solve this problem, in the prior art, ventilation holes are usually provided in the hull to ensure the balance of the air pressure inside and outside the hull. However, in the running process of the racing boat in water, a large amount of seawater can enter the boat through the vent holes and invade the interlayer of the boat body, so that the corrosion of the boat body structure is accelerated, and the service life of the boat body is shortened. To solve this problem, the applicant has previously filed a chinese patent publication No. CN217623996U, which discloses an atmospheric plug for racing boats comprising an elastic plug, a straight pull rod, and a cross bar. The elastic plug is a conical elastic piece and is sleeved at the tail end of the straight pull rod along the axis. The middle section of the cross rod is radially provided with a central hole which is in sliding connection with the straight pull rod, and annular flanges are arranged at the two ends of the straight pull rod. The whole structure of the scheme is simple, and the air pressure adjusting operation of the ship body interlayer can be realized through pushing and pulling. In the practical use process, the split type design of the combination of the hollow straight pull rod, the elastic plug and the hollow cross rod is adopted, the installation process is complex, the connection stability is low, and the hollow straight pull rod is high in hardness and low in toughness, so that bending deformation is very easy to occur in the process of accommodating the racing boat to the ship bag, a ventilation channel is blocked, the internal air pressure of the racing boat is larger than the external air pressure when the racing boat is directly sunned, the situation that the shell of the racing boat is broken is caused, the internal and external air pressure adjusting function of the hull cannot be realized, and the maintenance cost and the potential safety hazard are increased. Disclosure of utility model In order to solve the existing problems, the utility model adopts the technical scheme that the integrated atmospheric plug for the racing yacht is provided, and the problems of lower connection stability and poor exhaust effect of the existing atmospheric plug are solved. The ship body is arranged at an air vent of a ship body interlayer and is characterized by comprising an air vent section, a plug section, a straight rod section and a positioning section which are sequentially arranged and coaxially connected, wherein the positioning section is of a structure with a small upper end and a wide lower end, one end of the positioning section with a small radial length is connected with the straight rod section, a through exhaust pipe is arranged in the body, a first exhaust port communicated with the outside is arranged at the head end of the air vent section, a second exhaust port communicated with the outside is arranged at the joint of the positioning section and the straight rod section, and the exhaust pipe is communicated with the first exhaust port and the second exhaust port. Preferably, the plug section has a conical truncated cone structure, and the diameter of the cross section of the plug section decreases towards the direction approaching the straight rod section. Preferably, the two sides of the positioning section are symmetrically provided with raised barbs. Preferably, the barbs are disposed at a maximum radial length of the positioning segment and extend to the distal end of the positioning segment. Preferably, the positioning section is of a drop-shaped structure, and a drop-shaped cavity matched with the outer contour of the positioning section is arranged in the center of the positioning section. Preferably, the diameter of the cross-section of the venting section gradually decreases in a direction away from the plug section. Preferably, two ends of the choke plug section are respectively provided with an arc-shaped transition section, one arc-shaped transition section is connected with the ventilation section, and the other arc-shaped transition section is connected with the straight rod section. Preferably, the round platform edge of the plug section is a round angle. Preferably, the exhaust pipe is disposed coaxially wi
