Abstract
The present utility model relates to a waterproof wide-angle eyepiece for an astronomical telescope. The eyepiece comprises a lens A, a lens B, an eyepiece frame, a space ring A, a space ring B, a clamping ring, a front mirror framework, and a steel sleeve. The eyepiece is characterized in that a sealing ring A is arranged between the lens A and the eyepiece framework, a sealing ring C is arranged between the eyepiece framework and the steel sleeve, a sealing ring D is arranged between the lens B and the front mirror framework, a sealing ring E is arranged between the front mirror framework and the steel sleeve; an air vent A is arranged on the space ring A, an air vent B is arranged on the space ring B, an air vent D is arranged on the clamping ring, an air vent C and a ventilation groove are arranged on the eyepiece framework; a screw is connected with a sealing ring B by the air vent C, and the head of the screw is also sealed with sealant. As the sealing rings are combined tightly with parts, the aim of preventing water and mildew permanently can be realized.
Description
Technical field
The utility model relates to the astronomical telescope technical field, and the wide-angle eyepiece that specifically on astronomical telescope, uses is introduced waterproofing design.
Background technology
The wide-angle eyepiece that astronomical telescope is used is owing to the edge picture element that surprising visual field, high-quality are arranged, and complicated structure and fancy price, is the important accessory that each astronomical worker treasures very much.Making moist, mildewing is the formidable enemy of eyepiece.Eyeglass makes moist, mildews, becomes above mechanical damage to cause the eyepiece performance to descend, even the main reason of scrapping.For keeping eyepiece to avoid invading and harassing, former best mode is that eyepiece is placed in the drying box, has both increased volume and weight, is difficult to avoid the damage that unfavorable natural cause caused in use again.
The utility model content
The purpose of the utility model provides a kind of astronomical telescope with waterproof, antimildew function and uses wide-angle eyepiece.
The technical scheme of the utility model is: astronomical telescope comprises lens a, lens b, eyepiece frame, spacer ring a, spacer ring b, trim ring, preceding picture frame, steel bushing etc. with the waterproof wide-angle eyepiece; It is characterized in that: O-ring seal a is set between lens a and eyepiece frame, O-ring seal c is set between eyepiece frame and steel bushing, between lens b and preceding picture frame, O-ring seal d is set; O-ring seal e is set between preceding picture frame and steel bushing; Air hole a is set on spacer ring a, air hole b is set on spacer ring b, air hole d is set on trim ring; Air hole c and air channel are set on eyepiece frame, are communicated with inner each optical surface of eyepiece through air hole and air channel; Air hole c attachment screw and O-ring seal b add the sealing of fluid sealant secondary at head of screw.
After taking into the air of inside away the vacuum shape, charge into inert gas through air hole c; With screw and O-ring seal this unique blow vent that communicates with the external world is sealed; Again head of screw add fluid sealant secondary sealing; Make whole celestial body eyepiece inside reach fully and extraneous no any UNICOM, finally realize the function of waterproof, mildew-resistant.
The utility model astronomical telescope is with elements such as waterproof wide-angle eyepiece utilization O-ring seal, air hole, air channel, fluid sealant, screw and inert gases; By combining closely between O-ring seal and each part; Through various passages with the eyepiece internal communication; Charge into inert gas sealing after vacuumizing, the inside and the external world of eyepiece isolated up hill and dale, reach permanent waterproof, mildew-resistant.The utility model is to introduce waterproofing design at astronomical telescope first in wide-angle eyepiece.
Description of drawings
Fig. 1 is the structural representation of the utility model astronomical telescope with the waterproof wide-angle eyepiece.
Among the figure, 1. O-ring seal a, 2. air hole a, 3. air hole b, 4. screw, 5. fluid sealant; 6. O-ring seal b, 7. air hole c, 8. air channel, 9. air hole d, 10. O-ring seal c; 11. lens a, 12. spacer ring a, 13. spacer ring b, 14. eyepiece frames, 15. trim rings; 16. O-ring seal d, 17. lens b, 18. O-ring seal e, 19. preceding picture frames, 20. steel bushings.
Embodiment
As shown in Figure 1; The utility model astronomical telescope is made up of lens a11, lens b17, eyepiece frame 14, spacer ring a12, spacer ring b13, trim ring 15, preceding picture frame 19, steel bushing 20 etc. with the waterproof wide-angle eyepiece; Between lens a11 and eyepiece frame 14, O-ring seal a1 is set; Between eyepiece frame 14 and steel bushing 20, O-ring seal c10 is set, between lens b17 and preceding picture frame 19, O-ring seal d16 is set, between preceding picture frame 19 and steel bushing 20, O-ring seal e18 is set; Optical element and structural member and O- ring seal 1,10,16,18 are combined closely, make eyepiece self reach the optical design performance requirement; Air hole a2 is set on spacer ring a12, air hole b3 is set on spacer ring b13, air hole d9 is set on trim ring 15, air hole c7 and air channel 8 are set on eyepiece frame 14, be communicated with inner each optical surface of eyepiece through air hole 2,3,7,9 and air channel 8; Air hole c attachment screw 4 and O-ring seal b6; Head of screw 4 adds the sealing of fluid sealant 5 secondaries; As sealed piece, make whole celestial body eyepiece inside reach fully and no any connection of the external world with screw 4 and O-ring seal b6 and fluid sealant 5, finally realize the function of waterproof, mildew-resistant.
