Description

The supporting adjustable volume support of skiascope

Technical field

The utility model belongs to eye and regards optical test equipment, and in particular to a kind of supporting adjustable volume support of skiascope.

Background technology

Skiascope is illuminated using itself light-source system to eyeball inside, and light can return from retinal reflex, these Reflection light is changed after the dioptric composition of eyeball, and the vergence by checking reflection light may determine that bending for eye Luminous power.The composition of skiascope includes optical projection system（Light source, focus lamp, speculum and focusing sleeve pipe）, observing system（Peephole, put down Face mirror）And volume support.E Tuo mainly plays a supportive role：When user is using skiascope inspection shadow, volume support is first propped up into oneself observation The geisoma of eye（Correct position）, observing eye is observed the reflective of examinee's retina by peephole just；User exists Skiascope can be moved by a small margin during inspection shadow.Therefore the design of volume support must is fulfilled at 2 points：When its length and（Away from peephole） Height will meet the requirement of " making peephole be located exactly at immediately ahead of observing eye "；Second, width is suitable, avoid Yin Etuo wide and Influence the flexibility of skiascope movement.The volume support for the skiascope commonly used on the market at present is fixed, length 28mm（Wherein Leading edge and the horizontal range about 6mm at peephole center）, height（E Tuo most lower edges and the vertical range at peephole center）About 20mm；Volume Support thickness is 5-8mm（Ramp type）.

During Clinical practice, it is found that the E Tuo of this regular length is only suitable for the user not worn glasses, for wearing The user of glasses（It especially can't skillfully grasp the young doctor of skiascope using skill）, using this skiascope mistake Cheng Zhonghui lacks support, causes the efficiency and accuracy for examining shadow to reduce because that can not contact volume support；And because users are usual Peephole can be directly against to eyeglass as support is substituted, eyeglass may be so oppressed, cause discomfort, in the mistake of mobile skiascope Also it can make or even wear eyeglass during journey dirty.

The content of the invention

The utility model provides a kind of skiascope supporting adjustable volume support, and it includes E Tuo and movable part, the volume The inside of support is provided with the storage tank for being used for placing movable part, and the side of the volume support is provided with track, and track connects with storage tank Logical, the both ends of the storage tank both sides are provided with locating slot；The end both sides integrally connected groove of the movable part, spring one end Bottom portion of groove, other end connecting partition are fixed on, the dividing plate is provided with a salient point, and the salient point is used for locating slot clamping Fixed movable part, integrally connected button on dividing plate, is slided and drives movable part to slide in orbit by button.

Preferably, the length of the volume support is 28, and width 22mm, the length of the movable part is 14mm, and width is 14mm。

Preferably, the movable part is made up of metal, and front end is wrapped up with rubber.

The length of volume support can be adjusted by movable part for the utility model, can make that wears glasses or do not wear glasses to make User can touch E Tuo, there is firm, the comfortable strong point during shadow is examined, and avoid causing to examine shadow due to a lack of support Efficiency and accuracy reduces and peephole directly is against into ophthalmic len and makes or even wears eyeglass dirty or cause to oppress.

Embodiment

The supporting adjustable volume support of skiascope that the present embodiment provides, as shown in Fig. 1~7, including volume support 100 and movable part Divide 200, movable part 200 is made up of metal material, and the front end rubber 900 of movable part 200 wraps up, according to the mirror eye distance of people （Distance of the summit to the preceding summit of cornea after ophthalmic len）, looks spacing（Geisoma and the air line distance of pupil center）, common spectacles Thickness of upper frame edge edge etc., it is length adjustable by existing fixed improvement, is designed to two length, both the volume support 100 Length be 28mm, width 22mm, the length of the movable part 200 is 14mm, width 14mm,

So that the horizontal range at the front end of volume support 100 to peephole center 810 is 6mm, the movable part 200 is stretched The horizontal range at front end to peephole center 810 is 20mm after coming.The profile of the volume support 100 and the volume support of conventional skiascope Shape is identical, and the inside of the volume support 100 is provided with the storage tank 110 for being used for placing movable part 200,110 liang of the storage tank The both ends of side are designed with locating slot 120, and two sides of the volume support 100 are designed with track 130, and track 130 and storage tank 110 It is connected, integrally connected groove 300 on one end end both sides of the movable part 200, the bottom of groove 300 is fixedly connected Spring 400, the other end connecting partition 500 of spring 400, the dividing plate 500 are provided with a salient point 510, the salient point 510 with The clamping of locating slot 120 is used to fix movable part 200, and integrally connected button 600 on the dividing plate 500, the button 600 is by pressing Splenium 610 and slide bar portion 620 form, and are slided by slide bar portion 620 on track 130 and drive movable part 200 to slide, E Tuo 100 lower surfaces are provided with rubber ring 700, and volume support 100 is fixed on skiascope 800 by rubber ring 700.

When user wears glasses, can press button 600 compresses spring 400, and dividing plate 500 moves toward the bottom of groove 300, Salient point 510 separates with locating slot 120, movable part 200 is released further along, when the completely out storage tank 110 of movable part 200 When, the salient point 510 on dividing plate 500 is just corresponding with locating slot 120, and the resilience of spring 400 makes salient point 510 be stuck in locating slot 120, movable part 200 is fixed, then geisoma is leaned against the front end of movable part 200, if user does not wear glasses, by movable part Divide 200 to push back in storage tank 110, geisoma is directly leaned against the front end of volume support 100, can so ensure user during shadow is examined There is the firm strong point, without being limited by wearing glasses, inspection shadow that can be more preferably more steady.

Embodiment above is used for the purpose of that the utility model is described in detail, and not does any restrictions to it, This area other staff make any change in the case where not paying performing creative labour and replaced to the technical solution of the utility model Change, belong within the scope of protection of the utility model.
