Compared with the prior art, the eyepiece structure of the utility model has the advantages of compact structure, accurate diopter regulation, accurate positioning, water prevention, dust prevention, back stopping and the like, has exact positioning hand feeling, is reliable and guarantees that the eyepiece cannot rotate when being impacted or vibrated.
Description
Technical field
The utility model relates to goggle structure, especially a kind ofly can accurately regulate the goggle structure of diopter, can be widely used in the class optical articles of looking in the distance, and comprises telescope, gun sight, Target observator, astronomical telescope etc.
Background technology
The telescopic system eyepiece has the diopter regulatory function mostly, use with the people who satisfies different eyesights, but all goggle structures all can not accurately be adjusted diopter and accurately locate at present, and when being impacted or shake, eyepiece can rotate, and diopter value changes, and makes objective fuzzy unclear, need long time to the only position of user and will readjust, and the position that at every turn is adjusted to all has difference slightly.It as application number 99215722.6 Chinese utility model patent, " telescope ocular focus control " disclosed, it includes eyepiece stalk, eyepiece mount, focusing mount and pin, adopt eyepiece stalk, eyepiece mount, focusing mount coaxial package to be fixed on the assembly structure on the mirror body, and the bottom of eyepiece stalk forms with eyepiece mount, and the screw thread transmission cooperate, the top of eyepiece stalk cooperates with the transmission of focusing mount formative gear.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, a kind of simple and reasonable compactness is provided, location hand feeling is clear and definite, reliable, guarantees that eyepiece does not rotate when impacting or shake, and that can rotate at any time again simultaneously can accurately regulate the goggle structure of diopter.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind ofly can accurately regulate the goggle structure of diopter, the eyepiece mount that comprises eyepiece stalk, is connected through multi-step thread with eyepiece stalk, and be sheathed on adapter ring behind the eyepiece mount on the eyepiece mount, be embedded with the eyepiece group in the eyepiece mount, the end that eyepiece mount stretches into eyepiece stalk is fixedly connected with Non-return ring, have groove on one end side surface of Non-return ring, be provided with spring in the groove, apical grafting has locating ball on the spring, has one group of locating slot that axially is provided with and matches with locating ball on the eyepiece stalk.After regulating eyepiece mount during adapter ring, driving Non-return ring and eyepiece mount rotates together, make eyepiece move forward and backward, the realization diopter is regulated, and Non-return ring moves forward and backward in centring ring and relatively rotates simultaneously, and locating ball is just located in locating slot back and forth, send clear and melodious " clickly " sound, increased location hand feeling, when impacting and shake, prevented that eyepiece from rotating.
In order to obtain better technique effect, further technical measures also comprise:
Above-mentioned eyepiece stalk comprises the eyepiece urceolus and is fixedly installed in the interior centring ring of eyepiece stalk that locating slot is opened in the centring ring inwall.Locating slot is formed on independently on the parts, can makes making simpler, and, if locating slot weares and teares, only need to change small parts, the reduction maintenance cost.
Consider that employed strength is less in regulating the process of diopter, so the above-mentioned centring ring of the utility model and the eyepiece urceolus blended rubber that is threaded mutually is fixed together both.When assembling, both are conveniently linked together, and strength of joint has obtained sufficient assurance.
Above-mentioned Non-return ring and the eyepiece mount blended rubber that is threaded mutually is fixed together both.
Certainly, in adjustment process, making locating ball move needed power between locating slot is important problem, and therefore, above-mentioned locating slot is the R groove.Because the transition of R groove is smoother, therefore, required power is not very big, and is not easy locating slot is caused damage, prolongs serviceable life of the present utility model.
The end of above-mentioned Non-return ring is shaped on first teat, and the end of centring ring is shaped on second teat, and the external diameter of first teat is greater than the internal diameter of second teat.Guarantee that Non-return ring had both rotated freely, accurate positioning, " snap " sound is clear and melodious, prevents that again Non-return ring from deviating from centring ring, thereby can prevent that eyepiece from coming off, playing the retaining effect when positive diopter is regulated in eyepiece stalk.
Has first O-ring seal between the above-mentioned eyepiece mount eyepiece urceolus.The outer end of above-mentioned eyepiece group is provided with second O-ring seal.First O-ring seal and second O-ring seal can play waterproof effect, can also play the dustproof effect simultaneously, make the utility model still can keep its sharpness after long-term the use.
Compared with prior art, the end that eyepiece mount of the present utility model stretches into eyepiece stalk is fixedly connected with Non-return ring, has groove on the end side surface of Non-return ring, is provided with spring in the groove, apical grafting has locating ball on the spring, has one group of locating slot that axially is provided with and matches with locating ball on the eyepiece stalk.Have compact conformation, accurately adjust diopter, accurate location, waterproof, multiple advantages such as dustproof, retaining, and location hand feeling is clear and definite, reliable, guarantee that eyepiece is impacting or do not rotating during vibrations.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the synoptic diagram that cooperates of locating ball and locating slot among the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, figure grade explanation: eyepiece stalk 1, locating slot 1a, eyepiece urceolus 11, centring ring 12, the second teat 12a, eyepiece mount 2, adapter ring 3 behind the eyepiece mount, Non-return ring 4, groove 4a, the first teat 4b, spring 41, locating ball 42, the first O-ring seals 5, eyepiece group 6, the second O-ring seals 7.
Embodiment as shown in the figure, a kind ofly can accurately regulate the goggle structure of diopter, comprise eyepiece stalk 1, the eyepiece mount 2 that is connected through multi-step thread with eyepiece stalk 1, and be sheathed on adapter ring 3 behind the eyepiece mount on the eyepiece mount 2, be embedded with eyepiece group 6 in the eyepiece mount 2, the end that eyepiece mount 2 stretches into eyepiece stalk 1 is fixedly connected with Non-return ring 4, to be Non-return ring 4 be fixed together both with eyepiece mount 2 blended rubber that is threaded mutually its two connected mode, have groove 4a on one end side surface of Non-return ring 4, be provided with spring 41 in the groove 4a, apical grafting has locating ball 42 on the spring 41, have one group of locating slot 1a that axially is provided with and matches with locating ball 42 on the eyepiece stalk 1, locating slot 1a adopts the R groove in the present embodiment.
The eyepiece stalk of present embodiment comprises eyepiece urceolus 11 and is fixedly installed in centring ring 12 in the eyepiece stalk 11, to be centring ring 12 be fixed together both with eyepiece urceolus 11 blended rubber that is threaded mutually its two connected mode, and locating slot 1a is opened in centring ring 12 inwalls.
