Description

Place stable electron eyesight training appearance

Technical Field

The utility model relates to a detector field especially relates to a place stable electron visual training appearance.

Background

Compared with a common visual chart, the electronic vision detector is more comprehensive, accurate, portable and efficient, multiple innovative technologies are applied, the electronic vision detector has the advantages of simple structure, simplicity in operation, high efficiency, accuracy, various modes and the like, is suitable for ophthalmologic examinations such as visual quality assessment, vision screening, fitting lens assessment, daily physical examination and the like, and is mainly used for comprehensively detecting and assessing the daily visual function of human eyes. The electronic vision detector is generally placed on a table top, and when the electronic vision detector is used, different pictures are respectively displayed on the detector by operating the electronic vision detector through a worker, and the electronic vision detector can fall down by frequently pressing the electronic vision detector.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide one kind and place stable electron visual training appearance.

The utility model discloses a realize through following technical scheme: the utility model provides a place stable electron visual training appearance, includes braced frame, fixes the backup pad on braced frame and fixes the display screen on braced frame, first standing groove has been seted up to the lower surface of backup pad, the spout has been seted up on the upper inner wall of first standing groove, sliding connection has the draw runner in the spout, is fixed with the extension board on the draw runner, braced frame department is seted up in the screw hole of spout intercommunication is kept away from on the backup pad surface, and screw hole female connection has the depression bar, backup pad lower surface is close to braced frame and is located the both sides of standing groove and has seted up the second standing groove respectively, it has the inserted bar that stretches to the second standing groove to peg graft in the backup pad, the lower extreme of inserted bar is fixed.

The utility model has the advantages that: when using like this, at first make the extension board outwards slide out by the spout and increase the support area, thereby it can fix the extension board to make it tightly push down the draw runner through twisting the depression bar, because the display screen is the slope form, can give a backward power to the display screen during operation, can increase stability through increasing the support area like this, be unlikely to make whole turn over backward when the operation, and press the inserted bar simultaneously and make its rubber suction cup of lower extreme tightly adsorb, increased the land fertility of grabbing near display screen department like this, thereby further increased stability.

Drawings

fig. 2 is a rear view structure diagram of the present invention;

in the figure: 1. a support frame; 2. a support plate; 3. a display screen; 4. a first placing groove; 5. a chute; 6. a slide bar; 7. a lengthening plate; 9. a pressure lever; 10. a second placing groove; 11. inserting a rod; 12. a rubber sucker.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a braced frame 1, fix backup pad 2 on braced frame 1 and fix the display screen 3 on braced frame 1, first standing groove 4 has been seted up to the lower surface of backup pad 2, spout 5 has been seted up on the upper inner wall of first standing groove 4, sliding connection has draw runner 6 in the spout 5, is fixed with extension board 7 on the draw runner 6, braced frame 1 is located to offer in the screw hole of spout 5 intercommunication is kept away from on backup pad 2 surface, and screw hole female connection has depression bar 9, 2 lower surface lower surfaces of backup pad are close to braced frame 1 and are located the both sides of standing groove and have seted up second standing groove 10 respectively, it has the inserted bar 11 of stretching in second standing groove 10 to peg graft in the backup pad 2, the lower extreme of inserted bar 11 is fixed with rubber suction cup. 12

The utility model has the advantages that: when using like this, at first make extension 7 outwards slide out by the spout 5 and increase the support area, thereby can fix extension 7 through twisting depression bar 9 and make it tightly push down draw runner 6, because display screen 3 is the slope form, can give display screen 3 a backward power during the operation, can increase stability through increasing the support area like this, be unlikely to make whole turn over backward when the operation, and press inserted bar 11 simultaneously and make its rubber suction cup of lower extreme tightly adsorb, increased the power of grabbing ground near display screen 3 department like this, thereby further increased stability.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
