Description

Technical Field

[0001] The utility model relates to the technical field of kayak drainage, in particular to a kayak drainage plug. Background Art

[0002] Kayaking is a popular recreational and sports boat. When a kayak is traveling on the water, it will be affected by waves or the shaking of the hull, and water will enter the hull. When the amount of water is too large, it will affect the normal glide of the kayak. The drain plug in the kayak is vital to the kayak and is generally used for drainage. When draining water, the drain plug is opened by rotating the upper part of the drain plug.

[0003] The patent with the authorization announcement number CN210971450U discloses a canoe drain plug, including a plug cover and a fixed base connected to the plug cover. When the utility model is used, the fulcrum is placed at the arc-shaped groove, and the movable end is rotated. The movable end is set in a four-sided pyramid shape to increase the torsional strength of the movable end. The threaded connection is made at multiple locations to improve the stability of the connection. At the same time, the sealing gasket is located above the rotating hole to seal the connection between the plug cover and the fixed base. The canoe drain plug involved in the above patent uses a conventional threaded connection method to complete the sealing, but the threaded drain plug needs to be continuously rotated when drainage is required, and the speed of opening the drain port is slow. When in use, it takes a long time to work the knob, and the drainage efficiency is slow. Although the design of the base plate can prevent the drain plug from being lost, it also makes it impossible for the drain plug to be completely separated from the drain port. When draining, it needs to be picked up manually, which is time-consuming and labor-intensive. Summary of the invention
