Description

Technical Field

[0001] The utility model relates to a threaded fixed eye mask, belonging to the technical field of eyepieces. Background Art

[0002] The eyepiece is an important component used for observation in optical instruments such as microscopes and telescopes. It is an optical element usually located at the observation end of an optical instrument. Its function is to further magnify the image formed by the objective lens so that the human eye can clearly observe the details of tiny or distant objects. The eyepiece uses the refraction principle of the lens to perform a second magnification on the image formed by the objective lens. When the light passes through the objective lens to form an inverted, reduced real image, the real image is located near the focal plane of the eyepiece. The eyepiece then uses this real image as an object and further magnifies it into an upright, magnified virtual image for observation by the human eye.

[0003] The eyepiece is usually composed of the eyepiece body and the eyecup. If the eyecup is not replaced with a different model, the eyecup may fall off during actual use, affecting the normal use of the eyepiece. To this end, we provide a threaded fixed eyecup to solve the above problem. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a threaded fixed eye mask to solve the above problems. The specific technical solution is as follows:

[0005] A threaded fixed eye mask comprises an eyepiece external structural component, an eye mask component is provided on the left side of the eyepiece external structural component, a silicone sleeve is fixedly connected to the right side of the eye mask component, a plurality of eye mask connection grooves are formed on the outer surface of the silicone sleeve, and an eye mask locking component is provided inside the eyepiece external structural component.

[0006] Preferably, the outer surface of the eye mask locking piece is provided with three threaded protrusions, and the outer surfaces of the threaded protrusions are adapted to the inner wall of the eye mask connecting groove.

[0007] Preferably, an annular limiting end is provided inside the external structural component of the eyepiece, a buffer pad is fixedly connected to the left side of the annular limiting end, and the left side of the buffer pad contacts the right end of the eye mask locking member.

[0008] Preferably, a first through hole is provided on the right side surface of the eyepiece external structural component, and a second through hole is provided on the left side surface of the annular limiting end.

[0009] Preferably, a connecting thread is provided on the inner wall of the eyepiece external structural component, and the outer surface of each threaded protrusion is threadedly connected to the inner wall of the connecting thread.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The threaded eye mask is fixed, and the silicone sleeve and multiple eye mask connecting grooves provided on the eye mask part enable the threaded protrusions on the surface of the eye mask locking part to be inserted into the inside of the eye mask connecting groove, so that the silicone sleeve is firmly fitted on the surface of the eye mask locking part. The three threaded protrusions on the surface of the eye mask locking part cooperate with the connecting threads inside the external structural part of the eyepiece, so that the threaded protrusions can rotate on the inner wall of the connecting threads. Then, the eye mask locking part can be used to firmly connect the eye mask part to the external structural part of the eyepiece, thereby preventing the eye mask from falling off when replacing an eye mask of a different model, thereby ensuring the normal use of the eyepiece.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
