Description

The glasses display that the band diopter is regulated

1, technical field:

The utility model relates to the glasses display that the band diopter is regulated.

2, background technology:

As shown in Figure 1, glasses display mainly comprise micro display chips A and optical system B, send into people's eyeball after the image that the micro display chips that its principle utilizes optical system will be installed in the glasses the inside shows amplifies, micro display chips can receive and play from vision signals such as TV station, DND, VCD.But there is following shortcoming in the optical system of present glasses display: the system that diopter is regulated is not set, and not too comfortable when seeing because image is not too clear when the user uses glasses display, long-time use is relatively tired out and eyes is caused certain infringement.

3, summary of the invention:

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the glasses display that the band diopter is regulated, and it is easy to use comfortable.

The utility model is achieved by the following technical solution:

The glasses display that the band diopter is regulated comprises glasses housing, miniscope and two barrel assemblies, and wherein miniscope is installed in glasses housing the inside and shows and carries the video image of coming in; The barrel assembly the inside is equipped with the optical system of sending into people's eyeball after the image that micro display chips is shown amplifies, two barrel assemblies are installed on the glasses housing, wherein the barrel assembly the inside is provided with object lens, and barrel assembly is provided with the eyesight adjustment device that can adjust the distance between miniscope and the object lens.

Above-mentioned described this eyesight adjustment device comprises regulates rotation circle, extension spring, object lens are mounted in the objective tube, objective tube is enclosed within on the guide pillar of barrel assembly and can moves up and down, extension spring one end is connected on the barrel assembly, extension spring other end connector lens barrel, regulate the rotation circle and be installed on the barrel assembly, regulate the boss that arches upward gradually rotation circle top and withstand on the cross bar that stretches out the objective tube side.

Above-mentioned described optical system comprises object lens, balsaming lens, catoptron and eyepiece composition, and object lens are positioned at the miniscope below, and the below of object lens is balsaming lens and catoptron, and the catoptron left side is an eyepiece.

Above-mentioned described catoptron and inclined light shaft miter angle.

The utility model compared with prior art has following advantage: it is provided with eyesight adjustment device, can make the pleasant use glasses display of people, effectively lowers eye fatigue, and long-time the use damaged little, simple in structure, easy to use to eyes.

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is the fundamental diagram of traditional glasses display;

Fig. 2 is that the utility model is installed in a stereographic map on the glasses display;

Fig. 3 is that Fig. 2 turns over a view after the angle;

Fig. 4 is the structure principle chart that optical system is installed in the glasses display;

Fig. 5 is the structural drawing of the utility model eyesight adjustment device;

Fig. 6 is the explosive view of the utility model eyesight adjustment device.

5, embodiment:

As Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model comprises glasses housing 1, miniscope 2 and two barrel assemblies 3, and wherein miniscope 2 is installed in glasses housing 1 the inside and shows and carries the video image of coming in; Barrel assembly 3 the insides are equipped with the optical system 4 of sending into people's eyeball after the image that micro display chips is shown amplifies, two barrel assemblies 3 are installed on the glasses housing 1, wherein barrel assembly 3 the insides are provided with object lens 5, and barrel assembly 3 is provided with the eyesight adjustment device that can adjust the distance between miniscope 2 and the object lens 5.This eyesight adjustment device comprises regulates rotation circle 6 and extension spring 7, object lens 5 are mounted in 8 li of objective tubes, objective tube 8 is enclosed within on the guide pillar 10 of barrel assembly 3 and can moves up and down, extension spring 7 one ends are connected on the barrel assembly 3, extension spring 7 other end connector lens barrels 8, regulate rotation circle 6 and be installed on the barrel assembly 3, regulate the boss 9 that arches upward gradually rotation circle 6 tops and withstand on the cross bar 11 that stretches out objective tube 8 sides.

Above-mentioned optical system 4 comprises object lens 5, balsaming lens 12, catoptron 13 and eyepiece 14 compositions, and object lens 5 are positioned at miniscope 2 belows, and the below of object lens 5 is balsaming lens 12 and catoptron 13, and catoptron 13 left sides are eyepieces 14.Catoptron 13 and optical axis 15 inclination miter angles plate reflective membrane on the catoptron 13.

The principle of work of eyesight adjustment device of the present utility model: forward rotation is regulated rotation circle 6, the boss 9 of regulating rotation circle 6 tops withstands on the cross bar 11 of objective tube 8 sides, overcome extension spring 7 pulling force impellent lens barrels 8 and move on gradually, the object lens 5 that make objective tube 8 are near miniscopes 2; Backward rotation is regulated rotation circle 6, the boss 9 of regulating rotation circle 6 tops leaves on the cross bar 11 of objective tube 8 sides gradually, impellent lens barrel 8 moves down gradually under extension spring 7 pulling force effects, the object lens 5 that make objective tube 8 are away from miniscope 2, therefore, can adjust distance between object lens 5 and the miniscope 2 by eyesight adjustment device, reach the purpose of adjusting diopter.
