Fishing optical telescope

Abstract

A fishing optical telescope disclosed by the present invention comprises a telescope, a first ocular lens and a second ocular lens are connected at the top of the telescope separately, and a movable pillar is connected between the first ocular lens and the second ocular lens. A lens body is connected at the lower sides of the first ocular lens and the second ocular lens, a first objective lens cone and a second objective lens cone are connected at the tops of the left and right sides of the lens body respectively, and the left and right sides of the lens body are connected with a first rotating cylinder and a second rotating cylinder movably. A fixing pillar is fixedly connected at the left side of the first rotating cylinder, a moving cylinder is connected with the left side of the fixing pillar movably, an elastic headband strip is connected at the left side of the moving cylinder movably, and a first rotating ball is connected between the elastic headband strip and the moving cylinder movably. According to the present invention, by the cooperation of an afterbrain fastening belt, a telescopic device and a gear buckle, the telescopic device controls the afterbrain fastening belt to telescope, and secondly the gear buckle adjusts the tightness degree of the afterbrain fastening belt.

Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to an optical telescope for fishing. Background technique [0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. The refraction of the light through the lens or the reflection of the light by the concave mirror make it enter the small hole and converge into an image, and then pass through a magnifying eyepiece to be seen. Also known as "telescope". The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see details with smaller angular distances. The second function of the telescope is to send the light beam collected by the objective lens that is much thicker than the diameter of the pupil (up to 8 mm) into the human eye, so that the observer can see faint objects that were originally invisible. In 1608, Hans Libercy, a Dutch optician, ac...

Problems solved by technology

In 1609, Galileo Galilei, a Florentine in Italy, invented the 40x double-mirror telescope. This was the first practical telescope to be put into scientific applications. There are countless designs of telescopes on the market. Secondly, telescopes are also used in fishing. There are many, which is convenient for viewing the swim bladder. Secondly, when fishing in summer, the weather is too hot, which makes users feel uncomfortable wearing this kind of telescope, and many users are unwilling to buy and use it.
