Portable insect catching net

Abstract

The invention provides a portable insect catching net in order to reduce physical output of an entomological researcher during outdoor work. The technical scheme of the invention is that: the portable insect catching net comprises a net bag 1 and a telescopic net handle 6, and also comprises a circular arc-shaped telescopic rod and a movable ring 3, wherein the middle position of the circular arc-shaped telescopic rod is fixedly connected with the telescopic net handle 6 through a connecting bolt 5, the circular arc-shaped telescopic rod can stretch out circular arc-shaped slender rods respectively along the left end and the right end of the circular arc-shaped telescopic rod, the left circular arc-shaped slender rod and the right circular arc-shaped slender rod get in contact with each other to form a net ring 2 after running a circle, and are fixedly connected with each other at a contact position through a fixing bolt 4, the movable ring 3 is sleeved at the outer part of the circular arc-shaped telescopic rod, and can slide on the net ring 2 formed by the circular arc-shaped telescopic rod, a rim of the net bag 1 is connected with the movable ring 3, a fastening slit 10 is formed in the rim of the net bag 1 close to the fixing bolt 4, and a fastener 11 and a fastening hole are correspondingly arranged at two sides of the fastening slit 10. The whole insect catching net can be conveniently folded; as the inner part of the hard structure of the whole insect catching net is hollow, weight of the whole insect catching net is reduced; and moreover the portable insect catching net is simple to operate, and is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of tools for field entomology research, and in particular relates to a portable insect net. Background technique [0002] Insect nets refer to nets used to catch insects that fly fast, are good at jumping and swimming in water. According to the habits and living environment of different insects, different insect nets need to be used. Insect nets can generally be divided into three types: catch nets, sweep nets and water nets. There are two ways to use the net to catch the net. One is to swing the bottom of the net bag upwards after the insects enter the net, and turn the bottom of the net together with the insects upside down; the other is to turn the handle of the net when the insects enter the net. The net mouth is turned downwards, and the insects are sealed at the bottom of the net. Sweep nets are used to catch insects that inhabit bushes or weeds. The specification structure is the same as t...

AI Technical Summary

Problems solved by technology

Known insect nets are generally longer and heavier, and in the process of actually catching insects in the field, researchers often work in the field for several days or even longer. Labor requires portable tools to minimize physical exertion, so it is necessary to invent a portable insect net
