Description
Technical field
This utility model relates to a kind of vision checkout equipment, specifically a kind of Scroll Vission detector.
Background technology
Vision detection is a pith of routine physical examination, detects table, make the most intuitively and accurately judging the vision condition of tester by standard vision.Common eye chart is subject to the impact of light when detecting, light is bad, just has no idea to detect accurately.The Vission detector improved, is made the form of lamp box, is solved the problem of light, but volume is large, carries inconvenience, uses limited flexibility, and easily damages.
Summary of the invention
For solving the technical problem of above-mentioned existence, this utility model provides a kind of Scroll Vission detector, and utilize LED light source to solve light problem, Scroll designs, without time save space, easy to carry.
For achieving the above object, the technical scheme that this utility model adopts is:
A kind of Scroll Vission detector, include standard visual acuity chart, LED light source and body, the front surface of described body is set to white light transmissive material, be light tight pliable material below, described standard visual acuity chart, be fixedly installed on body, front surface, described LED light source, be arranged at body, interior and be connected with the gauge tap be arranged on body, lateral margin, described body, top be fixedly installed handle, bottom be provided with buckle, described body, tubular can be rolled into along top edge and by buckle, fixing.
Be provided with draw-in groove bottom described body, in described draw-in groove, be placed with flexible finger bar.
Described LED light source is connected with attaching plug and built-in rechargeable battery respectively.
Described LED light source adopts LED string.
This utility model structure is simple, devise Scroll body and be positioned over inner LED light source, standard visual acuity chart is fixed on the surface of body, LED light source provides suitable detection light for standard visual acuity chart, the used time is not rolled into tubular by spool, reduction takes up room, and be convenient for carrying by handle, not fragile, safety durable, flexible finger bar is positioned in the draw-in groove bottom body, easy to use and storage, rechargeable battery and first two mode of power plug is adopted to obtain the power supply of LED light source, easy to use.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Fig. 2 is body interior views;
Fig. 3 is overview.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail:
As Figure 1-3, this Scroll Vission detector, include standard visual acuity chart 1, LED light source 2 and body 3, the front surface of described body 3 is set to white light transmissive material, such as thick matter plastics, solid, not easily fold, light transmission is good, be light tight pliable material below, described standard visual acuity chart 1 is fixedly installed on the front surface of body 3, described LED light source 2 is arranged in body 3, and be connected with the gauge tap be arranged on body 3 surface, described body 3 top is fixedly installed handle 32, bottom is provided with buckle 5, described body 3 can be rolled into tubular along top edge and be fixed by buckle 5.The thickness of described body 3 is 1/5 of common lamp box, thinner, more convenient when rolling.
As preferred mode, bottom described body 3, be provided with draw-in groove 31, be placed with flexible finger bar 6 in described draw-in groove 31, be convenient to take and receive, retractable, suitably can adjust according to the height of device hanging position.
As preferred mode, described LED light source 2 is connected with attaching plug 7 and built-in rechargeable battery 8 respectively, and built-in rechargeable battery 8 is for subsequent use, when can not use when power supply in junction chamber, if there is suitable indoor power supply socket, connect power supply by attaching plug 7.The mode of two kinds of acquisition power supplys, easy to use.Rechargeable battery 8 adopts lithium battery, and general 3-4 hour is full of, and sustainable 6-8 hour charges for subsequent use at ordinary times, when health check-up of going out is inconvenient to connect indoor power supply, provides power supply with rechargeable battery 8.
As preferred mode, described LED light source 2 adopts LED string, is fixed in body 3, and in the present embodiment, LED string is furnished into three rows and is fixed on the inner face of body 3, for standard visual acuity chart 1 provides the light source of enough brightness and uniformity.
This utility model in use, buckle 5 is opened, whole body 3 launches, hang in place by handle 32, if there is favorably situated supply socket, then inserted in socket by attaching plug 7 and obtain power supply, open the switch of LED light source 2, for standard visual acuity chart 1 provides brightness and the enough power supply of the uniformity.If there is no suitable supply socket, so just adopt rechargeable battery 8 for subsequent use to power, in the draw-in groove 31 bottom body 3, take out flexible finger bar 6, eyesight testing is carried out to tester.After test terminates, flexible finger bar 6 is returned in draw-in groove 31, is rolled into tubular and fixes with buckle 5, carrying by handle 32 is portable.
Certainly; above-mentioned explanation is not to restriction of the present utility model; this utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
