| 简介 |
The present invention relates to a lower frame for fixing an abalone farming net, wherein the lower frame is formed as a square frame, and thus coupled to a lower part of the net to form a bottom edge area. The lower frame for fixing an abalone farming net comprises : first to fourth units which are extended to cross each other in both directions at respective corners, wherein each of the first to fourth units is hollow; frame connection members for connecting facing terminal ends of the first to fourth units to each other; and horizontal support members which cross over a frame formation space region formed by the first to fourth units, and are coupled to the first to fourth units such that the first to fourth units are spaced apart from each other and parallel with each other. Here, each of the first to fourth units has a first portion which is horizontally extended, and a second portion which is extended from one end of the first portion in a direction perpendicularly crossing the extending direction of the first portion. The second portion has an insert tube part which protrudes in a direction parallel with the first portion to connect the horizontal support members. Each of the first to fourth units is composed of an upper division tube and a lower division tube which are separated from each other and thus locked into each other by a locking unit, while dividing the hollowness into two parts in a horizontal room along the length of the hollowness. According to the lower frame for fixing an abalone farming net, the lower frame can be manufactured by the insertion coupling without a fusion procedure, and ropes of the net can be easily combined with each other, and thus provides excellent assembling efficiency and manufacturing efficiency.COPYRIGHT KIPO 2015 |
