Description
Technical Field
The utility model relates to an eyesight detection device.
Background
The vision detection device among the prior art is provided with the visual chart including lamp house and setting up in the sheet metal of lamp house front end generally on the sheet metal, and the light source of lamp house can illuminate the visual chart, improves the display effect of visual chart. The traditional vision detection device is usually installed and fixed on the wall surface, is inconvenient to move, has certain requirements on the use environment, and needs to be close to the wall surface in the whole detection area. In addition, for the classic ETDRS chart, which usually includes three tables, i.e. table 1, table 2 and table R, the three tables need to be separately displayed during the test, so that the chart needs to be frequently replaced, and the conventional vision testing apparatus is inconvenient to operate.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to prior art not enough, the utility model provides a convenient visual detection device who removes to it can conveniently change the visual chart of show.
In order to realize the above object, the utility model provides an eyesight detection device, including a plurality of sheets that are printed different visual charts respectively and with a plurality of sheet metal cooperation installation box, support, the support is including pole portion, base, the box is installed in pole portion upper end, pedestal mounting at pole portion lower extreme, the box is provided with the LED lamp plate including the cavity in the cavity, the LED lamp plate will the cavity is separated for preceding cavity and back cavity, and the box front end is provided with the show window who communicates mutually with preceding cavity, and box one side is provided with the inserted hole that is linked together with the cavity.
The utility model has the advantages that: the support can be stably placed on the ground through the matching of the rod part of the support and the base, does not need to depend on a wall surface, has low requirements on the use environment, and can be conveniently moved; during the use, can will wait to detect the visual chart sheet metal and insert the preceding cavity through the inserted hole of box one side, illuminate through the LED lamp plate at sheet metal rear, make whole sheet metal can evenly give out light, and the show window can supply the visual chart to expose, and convenient the detection, other visual chart sheet metals can be put in the cavity of back, conveniently deposit, are difficult to lose.
Furthermore, the upper side and the lower side of the cavity are provided with slots which are matched and spliced with the edges of the upper side and the lower side of the LED lamp panel.
The further setting brings the following effects: when the LED lamp panel is inserted into the cavity, the upper side and the lower side of the LED lamp panel can be inserted along the slots, so that the LED lamp panel is installed at a fixed position, the stability of the distance between the LED lamp panel and the front thin plate is ensured, and the illumination is more uniform; in addition, it is right through the LED lamp plate the cavity is separated, makes the holistic structure of box compacter.
Further, the rod part is a telescopic rod part.
The further setting brings the following effects: the height of the lamp box can be adjusted by the aid of the telescopic adjusting structure, and applicability of the lamp box is improved.
Further, the base includes universal wheels.
The further setting brings the following effects: the universal wheels are convenient for the whole movement of the vision detection device.
