Description
The technical field is as follows:
the invention belongs to the technical field of inflatable fender equipment preparation, relates to fender sealing equipment, and particularly relates to an impact-resistant inflatable fender sealing pull ring; the effect of reducing impact force when connecting between a plurality of fenders is realized through setting up rotatable pull ring.
Background art:
the fender is placed at a wharf or a ship side and is mainly used for slowing down impact force between the ship and the wharf or between the ships in a shore approaching or mooring process and preventing or eliminating the damage of the ship and the wharf; due to the continuous increase of the volume and the weight of the ship, higher requirements are placed on the size and the number of the fender; the inflatable drum type fender in the existing rubber fender is most widely applied, but the single fender is not enough to bear the parking requirement of large ships, and in practice, a plurality of fenders are bound together by ropes to form a fender row or chain to deal with the parking of high-length ships. The sealing pull ring of a common inflatable fender is fixed and cannot move up and down, so that when a ship stops, the pull ring between the fender and the fender is subjected to overlarge impact force, the pull ring is broken easily to cause loss, and even the ship and a wharf are possibly damaged. Therefore, the design of the lower-swing type impact-resistant inflatable fender sealing pull ring has good economic benefit and social benefit.
The invention content is as follows:

When the inflatable fender is used, after the inflatable fender is filled, the lower sealing ring is sleeved into the circular table, then the circular table is inserted into the fender port, the fender port is clamped through the convex buckle, then the upper sealing ring is screwed into the circular table, the lower sealing ring is extruded to be in close contact with the fender port so as to be sealed, and then the bolt air plug is screwed into the circular table for fixing; after each fender is sealed through a sealing pull ring, a rope penetrates through the rotating pull ring to connect a plurality of fenders, and the rotating pull ring can rotate, so that impact force received by the sealing pull ring is reduced and the fenders are not easy to break when impact activity is met.
Compared with the prior art, the fender port is clamped and sealed by the arranged convex buckle and the lower hem; the rotary pull ring is fixed on the fender through the arranged bolt air plug; the impact force between the fenders is buffered through the arranged rotatable pull ring; the structure is simple, the principle is reliable, the preparation cost is low, and the application environment is friendly.
