Abstract
The invention provides a rolling curtain type protective device for a main lens cone of a telescope, belonging to the technical field of optical measurement equipment development. The roller shutter type protection device comprises a guide rail sealing structure and a roller shutter type execution structure, wherein the guide rail sealing structure comprises a lower guide rail, an upper cover plate, a U-shaped sealing strip and a B-shaped sealing strip, and the roller shutter type execution structure comprises four supports, two drums, a shielding cloth and a handle. By rotating the handle, the device can be matched with the working state of the telescope to realize opening and closing and realize basic dustproof and waterproof functions in the closed state.
Description
Technical field
The present invention relates to a kind of roller shutter type protective device for telescope body tube, belong to optical measuring apparatus Development Techniques field.
Background technology
Telescope belongs to precision optics equipment, but its working environment is often in plateau or field.The severe natural conditions such as sand and dust, rainfall be easy to cause telescope window even primary mirror damaged and polluted, have a strong impact on the performance of total system.
In order to address this problem, usually circular dome can be set up specially in order to protection system to ground formula telescope.But packaged type telescope is often just adopted and installs over cap additional or use the mode of tarpaulin to prevent sand and dust and rainwater from entering internal system, use inconvenience and aesthetic property is poor.Also there is no a kind of special arrangement for protecting it at present.
Summary of the invention
The object of the present invention is to provide a kind of roller shutter type protective device for telescope body tube, telescope duty can be coordinated to realize rapidly opened and closed and realize down basic dustproof and waterproof effect in off position.This structure has the advantages such as structure is simple, volume is little, lightweight simultaneously.
Technical scheme of the present invention is as follows:
For a roller shutter type protective device for telescope body tube, comprise guide rail hermetically-sealed construction and roller shutter type execution architecture; Described guide rail hermetically-sealed construction comprises lower guideway, upper cover plate, two single u-shaped sealing strips and four Type B sealing strips; Described lower guideway is installed on telescope body tube as the frame of this device, and upper cover plate is installed on lower guideway, and two single u-shaped sealing strips and four Type B sealing strips are between upper cover plate and lower guideway; Described roller shutter type execution architecture comprises four bearings, two reels, tilt and handles; Described four bearings are arranged symmetrically on four angles of lower guideway; Two reels are arranged in the mounting hole of four bearings; Tilt is through U-shaped sealing strip and Type B sealing strip and two ends are separately fixed on two reels; Handle can insert in the handle socket of reel side.
Further, opens unthreaded hole in the middle of described tilt, side is dovetail type structure, for U-shaped sealing strip inner side fixture block clamp.
Further, described U-shaped sealing strip adopts three layers of fixture block structure, for longitudinal register and the sealing of tilt.
Further, described Type B sealing strip adopts hollow-core construction, is fixed on lower guideway and upper cover plate, and the two Type B sealing strips be mounted opposite under top compress tilt, realize transverse sealing.
The present invention, compared with existing dome, over cap or tarpaulin, has the following advantages and high-lighting effect:
Owing to present invention employs roller shutter type structure, one-piece construction comparatively dome type structure small volume and less weight, do not affect telescope performance; The present invention be custom-designed can open and close type safeguard structure, with over cap with tarpaulin structure compared is compact, easy to operate, good looking appearance; The present invention adopts rubber weather strip structure, can realize dust-proof, waterproof and basic airtight requirement.

Embodiment
Below in conjunction with accompanying drawing, structure of the present invention, principle of work and the course of work are described further.
Fig. 1 is the roller shutter type protective device axonometric drawing for telescope body tube, employing actual ratio is drawn, Fig. 2 is the roller shutter type protective device schematic diagram for telescope body tube, for more clearly representing architectural feature, the structure less to size has carried out amplifying process, and Fig. 3 is that tilt launches schematic diagram.Figure comprises upper cover plate 2, handle 5, four sliding bearings 6, two reels 7, tilt 8, four bearings 9 and body tube 10; Described two reels 7 are arranged on bearing 9 by four sliding bearings 6; Leave light hole in the middle of described tilt 8, two ends distribution is connected on two reels 7; Handle 5 can insert two reels 7 respectively and drive spool turns.When telescope works, the light hole on tilt 8 aligns with the light hole on lower guideway, and light can enter telescope body tube 10 by this device, as shown in Figure 1.When telescope quits work, turning handle 5 rotates with movable reel 7 thus the tilt 8 be fixed on reel 7 is laterally moved, until light hole part is rolled onto on reel 7 completely on tilt, light, dust and water all cannot enter telescope body tube 10, realize dust seal effect, as shown in Figure 2.When telescope needs again to enter duty, handle 5 is inserted another one reel 7, turning handle 5 also drives tilt 8 to do counter motion, until the light hole on tilt 8 aligns with the light hole on lower guideway.
Fig. 4 is the horizontal cut-away diagram of protective device, and Fig. 5 is the longitudinal cut-away diagram of protective device.Comprise lower guideway 1, upper cover plate 2, U-shaped sealing strip 3, Type B sealing strip 4, reel 7, tilt 8 and bearing 9.Described two single u-shaped sealing strips 3 are laterally arranged on lower guideway 1 both sides, are compressed by upper cover plate 2; Described four Type B sealing strips 4 are longitudinally arranged on lower guideway 1 and upper cover plate 2, compress tilt 8, realize transverse sealing by the extruding of lower guideway 1 and upper cover plate 2.Described tilt 8 both sides adopt dovetail type structure, with U-shaped sealing strip 3 inner side fixture block clamp the longitudinal register and sealing that realize tilt 8.
Non-elaborated part of the present invention belongs to the known technology of those skilled in the art.
