Description

The panorama sight glass

The utility model relates to optical instrument, particularly has the sight glass of all visual functions.

Traditional sight glass as telescope, periscope, can only be observed the place ahead, and its visual field is narrow, and when needs carried out the panorama observation, the observer must rotate together with sight glass and observe.Existing panorama facilities for observation is an a kind of indirect observation system, adopts the supporting a plurality of displays of a plurality of viewing heads to enlarge field of view; Adopt constantly rotation and the stored digital thermal imaging system of scene on every side but also have, the observer selects the image stored as required, but be subjected to the rotation of thermal imaging system and the restriction of display visual field, in a moment, also can only see the sub-fraction of complete cycle image, and can not obtain the panorama picture.

Given this, the purpose of this utility model is to provide a kind of panorama sight glass that can carry out Direct observation.

The utility model is according to light reflection principle, employing can reflect the panorama catoptrons of 180 ° in the place ahead and the 180 ° of images in rear and coupling look before and look back mirror and realize its purpose.

Panorama sight glass of the present utility model (referring to accompanying drawing), comprise lens barrel, the scape window on lens barrel top, the form of lower end (6), the catoptron that matches with scape window and form in the lens barrel, above-mentioned scape window has the ring window (2) of its center line and lens barrel center line annular in the same way and the lens barrel upper end skylight (4) to upper process, above-mentioned catoptron has at its short direction of lens barrel central upper portion panorama catoptron (7) along the similar half ellipsoidal surface shape of fore-and-aft direction, have on the lens barrel of the short direction of panorama catoptron have a down dip look preceding mirror (15) and look mirror (16) afterwards, the switching mechanism of above-mentioned panorama catoptron has the semiaxis (10) of lens barrel lower end and the rotating shaft (9) that is bearing on the lens barrel and links to each other with the panorama catoptron through the belt gear auxiliary driving, and above-mentioned form is at the lens barrel centerline direction.

There is spherical linkage (17) to link between mirror and the rear portion of looking back mirror and the lens barrel before above-mentioned the looking.

The utility model panorama catoptron, with the image of the 180 ° of scopes in the place ahead and rear reflex to respectively look before mirror and looking on the mirror of back, through the form of below observe look before on the mirror the place ahead scope image and observe the image of looking rear scope on the mirror of back, have can Direct observation the function of scene on every side.Observe the function of overlooking the panorama scene, then have when becoming to look up state and observe the function of looking up the panorama scene if having when adopting switching mechanism upset panorama anaglyphoscope to become to overlook state.Limit light shield can be respectively all or partly block ring window and skylight in addition, disturb and prevent to look up that the light from the ring window disturbs when observing and prevent to overlook when observing light from the skylight.

The utility model can be used as television camera, photograph resembles the machine full shot.Carry out 360 ° of visual fields shootings and supervision, also can directly be used as the sight glass of public place, prison, hospital, warehouse, place of military importance, also can be used as tank, panzer, submarine, aviation and extraordinary sight glass.

Below, with embodiment and accompanying drawing thereof the utility model is elaborated again.

Brief description of drawings.

Embodiment

A kind of panorama sight glass of the present utility model is shown in Fig. 1～3.Constitute by the catoptron in lens barrel and the lens barrel.

Above-mentioned lens barrel is square tube shape, also can be cylindrical shape or rib square tube shape.Constitute with common fixing structure connection by four sections.The lower end be opaque material system stack shell 1, be right after ring window 2, connect the stack shell 3 of opaque material system again for transparent material system, skylight 4 to upper process is all made with transparent material for ring week and top board in the upper end.The limit light shield 5 that is the tubular that is slidingly matched with its side face is arranged outside lens barrel, and the limit light shield can block the ring portion in ring window 2 or skylight 4.The limit light shield can also increase the limit light shield of the tubular that top board is arranged of a similar camera lens lid sample again, is exclusively used in and blocks whole skylights 4.In the lens barrel lower end is that stack shell 1 lower side is opened the form 6 that is shaped on hole shape.

Above-mentioned catoptron has the panorama catoptron, looks preceding mirror, looks the back mirror.Specular material and substrate that panorama catoptron 7 usefulness are common are made, and its reflecting surface is similar half ellipsoidal surface shape, are fixedly connected with support 8 in its bottom with screw.Support 8 connects firmly with rotating shaft 9, rotating shaft 9 axially and the length direction of panorama catoptron in the same way, rotating shaft 9 two ends are rotatably supported on the above-mentioned stack shell 3.At above-mentioned stack shell 1 suitable position, be equiped with semiaxis 10 rotationally, the end that semiaxis 10 stretches out stack shell is equipped with turn-knob 11, and the two driving-belt 14 of power wheel 12 and power wheel 13 and driving coupling is housed respectively in the inner of semiaxis and corresponding rotating shaft, constitutes the belt gear pair.Rotate knob 11, rotate together with panorama catoptron 7, the panorama catoptron is changed into be state of overlooking shown in the solid line and the state of looking up shown in dotted line through the secondary driving of belt gear rotating shaft 9.

Mirror 15 and look back mirror 16 before above-mentioned the looking lays respectively on the stack shell 3 of front and back of short direction of panorama catoptron 7, and its structure is identical, is to be symmetrical arranged.Mirror 16 usefulness specular material and substrate are made the plane catoptron after looking preceding mirror 15 and looking, and also can make the arc surfaced catoptron, and its rear portion joins with support 18 hinges of common spherical linkage 17 with corner block shape, and support 18 usefulness screws connect firmly on stack shell 3.

Thereby constitute this panorama sight glass.

During use, this panorama sight glass is installed into the front and back of the short direction of its panorama catoptron 7 along the observer, and maintain static as the observation center.When panorama catoptron 7 is when overlooking state, available limit light shield blocks the incident illumination in skylight 4, and then the scene in 180 ° of scopes in the place ahead of 90 ° of this depression angles, center enters from encircling window 2 the place aheads, through the front side of panorama catoptron 7 direct reflection mirror 15 before look; Simultaneously, the scene in the 180 ° of scopes in rear enters from encircling window 2 rears, reflex to through the trailing flank of panorama catoptron 7 and look back mirror 16, before the heart channel of Hang-Shaoyin form 6 is observed and is looked in the observation mirror 15 and look after mirror 16, directly taking in the depression angle is the panorama image of 90 ° of scopes.When panorama catoptron 7 is when looking up state, available limit light shield blocks the incident illumination of ring window 2, and then this center is looked up scene in the 180 ° of scopes in the place ahead at 90 ° at angle 4 front upper places are entered from the skylight, through the front side of panorama catoptron 7 direct reflection mirror 15 before look; Simultaneously, 4 back upper places enter the scene in the 180 ° of scopes in rear from the skylight, through the rear side direct reflection of panorama catoptron 7 to looking back mirror 16, mirror 15 and look back mirror 16 before the heart channel of Hang-Shaoyin form 6 is observed and looked in the observation, directly taking in and looking up the angle is the interior panorama pictures of 90 ° of scopes.The light reflection paths that has shown sight spot, dead ahead A when overlooking, sight spot, right front B, sight spot, left front C, sight spot, dead astern a, sight spot, right back b, sight spot, left back c among Fig. 1 and Fig. 3.
