Problems solved by technology

The protective cover is easy to lose. In order to ensure the convenience of use, there are still gaps, which cannot guarantee good dustproof performance; there are dustproof covers that are hung on the scope with ropes or rubber belts. It is the vibration and impact of the firearm that will drive the dust cover to shake, sometimes hitting the user's head or eyes, which has certain disadvantages; while the other kind of dust cover is hinged and mounted on the scope. The cover will not shake, but it will block the user's line of sight to a certain extent

Abstract

The invention discloses a dust-proof lens cover for a scope, which comprises: a dust-proof cover installation sleeve and a dust-proof cover; the installation sleeve is in the shape of a cylinder and matches the eyepiece barrel or objective lens barrel of the sight ; The installation sleeve is provided with a hinge seat; the end of the installation sleeve is provided with a locking outer flange; the inner side of the locking outer flange is provided with a locking inner flange receiving groove; The dust cover is disc-shaped; the dust cover includes a fixed ring, a transparent lens, and a hinged seat of the dust cover; the fixed ring is ring-shaped, and the fixed ring is provided with a transparent lens mounting groove and a locking inner flange; The transparent lens is set in the transparent lens installation groove; the inner side of the locking inner flange is provided with a locking outer flange receiving groove; the present invention is simple in structure and easy to use, and the use of the transparent lens can achieve the purpose of dustproof without hindering the aiming , does not block the line of sight; the use of torsion springs can make the dust cover pop open automatically, and the rotatable dust cover is more user-friendly and easy to use.

Description

technical field [0001] The invention belongs to the technical field of dustproof scope, and in particular relates to a dustproof mirror cover for scope. Background technique [0002] The scope is a relatively sophisticated optical device. Dust floating in the atmosphere, etc., is easy to adhere to the lens. When the dust adheres to the lens, it needs to be cleaned in time. If it is not cleaned in time, it will seriously damage the lens; The inside of the scope has a greater impact on the scope; the shell of the scope generally adopts an integrated processing design. After the dust enters, the scope needs to be disassembled for cleaning. Some lenses are fixed by glue, which is difficult to disassemble. After such a part enters the dust, it is more difficult to clean. [0003] Therefore, most scopes are equipped with dust caps, and ordinary dust caps are usually placed on the eyepiece. When using the scope, remove it. The protective cover is easy to lose. In order to ensure...
