Abstract
The utility model discloses a sipit preventing eyepiece cap comprising an eyepiece sleeve, an eyepiece cap body and a rotating shaft, wherein the eyepiece cap body and the eyepiece sleeve are movably connected through the rotating shaft; the eyepiece cap body realizes opening and closing by rotating around the rotating shaft; and the eyepiece sleeve is provided with a positioning block which can lead the eyepiece cap body to conduct 180-degree turnover only. After the eyepiece cap body is opened, the upper surface of the eyepiece cap body is parallel to that of an eyepiece, a user uses one eye to observe a target object through the eyepiece, and the other eye is just blocked by the eyepiece cap body, therefore, the user can still clearly observe the target without sipit. The eyepiece cap is applicable to all the optical instruments needing single eyepiece for observation such as monocular tube microscopes, astronomical telescopes, cameras, night-vision devices, rangers, spotting scopes and the like. Compared with the prior art, the eyepiece cap not only can protect the eyepiece, but also can facilitate observation of the user, and has the advantages of simple and practical structure and humanistic design.
Description
Technical field
The utility model belongs to the optical instrument technical field, especially a kind of multiduty anti-blink eyepiece cap.
Background technology
Existing a lot of optical instruments, such as monocular tube microscope, astronomical telescope and camera or the like, all be to arrive eyes by single eyepiece to be received, because we generally are in order to differentiate the very little object of field angle, so people have such impression by optical instrument by the people, opening eyes wide observes, it is severe more that other eyes must close, and the time has been grown, and can cause closed eyes very tired and painful.
The utility model content
The purpose of this utility model is the deficiency that exists at the above optical instrument, provides a kind of and can protect eyepiece, can be convenient to the anti-blink eyepiece cap of many usefulness that the user observes again.
To achieve these goals, the utility model is achieved in that anti-blink eyepiece cap, comprises eyepiece cover, eyepiece lid and rotation axis, and eyepiece lid and eyepiece cover flexibly connect by rotation axis, and the eyepiece lid moving axis that rotates is realized its unlatching and closure; The eyepiece cover is provided with and makes can only overturn 180 ° locating piece of eyepiece lid.After the eyepiece lid opened, its upper surface was parallel with the eyepiece upper surface, and the user uses that wherein eyes are by eyepiece object observing object, and other eyes are just blocked by the eyepiece lid, made the user still can clear object observing under the situation of blink not.
The end outer wall of described eyepiece cover is provided with first retention mechanism, eyepiece lid inwall is provided with second retention mechanism that matches, when the eyepiece lid was closed in the end of eyepiece cover, second retention mechanism was connected with first retention mechanism is closed, plays the effect of dustproof and waterproof.
Described first retention mechanism can be arranged on the fin on the end outer wall of eyepiece cover, and second retention mechanism can be arranged on the groove that matches on the eyepiece lid inwall.
The end outer wall and the eyepiece lid inwall of described eyepiece cover are provided with check washer.
The utility model is applicable to that monocular tube microscope, astronomical telescope, camera, night vision device, stadimeter, rifle the optical instrument that all need be observed by single eyepiece such as take aim at.Compared with prior art; the utility model solves viewing optics instrument eyes and wants closed problem; allow optical user under the situation that eyes are opened, can differentiate the small objects that to observe preferably; can protect eyepiece; can be convenient to the user again and observe, and have advantage simple in structure, practical, that design is rich in hommization.
Description of drawings
Fig. 1 is the schematic perspective view of the anti-blink eyepiece cap embodiment of the utility model;
Fig. 2 is the cut-open view of the utility model blink eyepiece cap embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the anti-blink eyepiece cap of the utility model is described in detail.
Anti-blink eyepiece cap as depicted in figs. 1 and 2, comprises eyepiece cover 1, eyepiece lid 2 and rotation axis 3, and eyepiece lid 2 flexibly connects by rotation axis 3 with eyepiece cover 1, and eyepiece lid 2 moving axis 3 that rotates is realized its unlatching and closures; Eyepiece cover 1 is provided with and makes can only overturn 180 ° locating piece 6 of eyepiece lid 2.After the eyepiece lid opens, locating piece 6 is stuck on the position of 180 ° of its upper surface upsets parallel with the eyepiece upper surface eyepiece lid 2, the user uses wherein, and eyes pass through eyepiece object observing object, other eyes are just blocked by the eyepiece lid, make the user still can clear object observing under the situation of blink not.Eyepiece cover 1 can be made by resilient material, and its internal diameter is slightly smaller than the eyepiece external diameter, is enclosed within on the eyepiece housing closely to be connected with eyepiece.Eyepiece cover 1 and eyepiece lid 2 all are processed with axis hole, and rotation axis 3 is installed in the axis hole, and eyepiece lid 2 moving axis 3 that can rotate rotates.The end outer wall of described eyepiece cover 1 is provided with first retention mechanism 4, eyepiece lid 2 inwalls are provided with second retention mechanism 5 that matches, when eyepiece lid 2 was closed in the end of eyepiece cover 1, second retention mechanism 4 was connected with first retention mechanism is closed, plays the effect of dustproof and waterproof.Described first retention mechanism 4 can be arranged on the fin on the end outer wall of eyepiece cover 1, and second retention mechanism 5 can be arranged on the groove that matches on eyepiece lid 2 inwalls.The end outer wall and eyepiece lid 2 inwalls of eyepiece cover 1 are provided with check washer.
The utility model is not limited to above-mentioned embodiment, if to various start or modification does not break away from spirit and scope of the present utility model of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
