Fig. 4 is this utility model side stationary state structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail:
As Figure 1-4, a kind of collapsible examination of visual acuity lamp box, include casing 1 and visual acuity chart 2, described casing 1 is by the organic backboard 11 placed in turn from bottom to top, light guide plate 12, reflective membrane 13 and light bar 14 form, described visual acuity chart 2 is layed in the upper surface of light bar 14, described organic backboard 11 is divided into three parts from top to bottom in the longitudinal direction, and described three parts are connected by rotating shaft, in order to realize whole casing 1 to be folded to form small-sized casing, the surrounding of described casing 1 is provided with frame 17, on described frame 17, the junction of corresponding organic backboard 11 is respectively arranged with holder 19, in order to realize stationary state when casing 1 launches, the bottom of described casing 1 is provided with rechargeable battery 15 and external power supply plug 16, be connected with light bar 14 respectively.
As preferred mode, the top folded section of described casing 1 and bottom fold section respectively correspondence arrange magnetic piece, mutually adsorb both time folding.
As preferred mode, described visual acuity chart 2 outer surface, by dual press mold process, often uses not fragile.
As preferred mode, on described frame 17, the junction of corresponding organic backboard 11 is respectively arranged with groove 18, it is interior also slidably that described holder 19 is positioned over groove 18, and the both sides of the frame 17 that can place as required or side, as long as can play fixation.The position suitable of adjustable holder 19 in groove 18, when guaranteeing to use, casing 1 is in the optimum state trailed.
As preferred mode, wire casing 3 and automatic rebounding bobbin 4 are set bottom described casing 1, the power cord wrap that described external power supply plug 16 connects is on automatic rebounding bobbin 4, be positioned in wire casing 3, the length of convenient adjustment power line, the used time does not recoil in wire casing 3, saves space, easy to use.
As preferred mode, described casing 1 top is provided with link 5 and for placing the groove referring to bar 6, is launched to be suspended from suitable position by casing 1 during convenient inspection, takes out and refers to that bar 6 operates.
In the present embodiment, casing 1 overall length 100 cm, its middle and upper part and bottom are respectively 35cm, and mid portion is 30cm, wide 20cm, and expansion thickness is 1cm, long 35cm after folding, and thickness is 3cm, and lightweight, profile is ultra-thin, conveniently fold and carry.
