Description

Technical Field

[0001] The utility model relates to the technical field of fishing net production, in particular to a size measuring device for fishing net production. Background Art

[0002] As the name suggests, a fishing net is a net used for fishing. Ancient people used coarse cloth and hemp as raw materials and made fishing nets by bundling and rolling. Although this kind of fishing net is easy to rot and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, and the fishing tools are also advancing with the times. When the production is completed, in order to ensure whether it meets the requirements, a size measuring instrument is usually used to measure the finished fishing net.

[0003] Prior art CN209495634U proposes a size measuring device for fishing net production. By holding the hand-held plate, the pressure plate is pushed to drive the measuring table to move, so as to measure the inner diameter of the fishing net fixed on one side of the rubber pad on the hand-held plate. The measurement can be straight and accurate, and the fishing net can be fixed, which is convenient for measurement and suitable for promotion. Four sets of guide plates are arranged on the pressure plate. The guide plates have the function of moving straight in the through groove when the pressure plate is moved, thereby ensuring the stable movement of the measuring table without tilting, etc. The measurement is accurate and the structure is simple.

[0004] The prior art usually uses a single measuring frustum to measure the holes of a fishing net. However, since the size requirements of different fishing nets are different, incompatibility may occur when the measuring frustum is used. Utility Model Content
