Detailed description of the invention
By further illustrating the technological means and merit that this utility model taked by reaching predetermined technique purpose
Effect, below in conjunction with accompanying drawing and preferred embodiment, to structure of the present utility model, feature and effect specifically
Bright as follows.
It is an embodiment of the present utility model as shown in Figure 1, Figure 2, Figure 3, Figure 4, in this embodiment
The near-sighted adjustment structure of virtual implementing helmet, including display device gripper shoe 1 and transmission support plate 3, display
Equipment gripper shoe 1 and transmission support plate 3 be arranged in parallel, and the two is combined by some screw thread pairs and regulates spacing,
It is provided with rotation regulation wheel 2 on transmission support plate 3, rotates regulation wheel 2 driving gear drive, gear
Drive mechanism drives screw thread pair to rotate, and then between regulation display device gripper shoe 1 and transmission support plate 3
Spacing.
Specifically, when screw thread pair rotates, transmission support plate 3 keeps fixing, and display device gripper shoe 1 is relative
Transmission support plate 3 moves forward and backward.
In the present embodiment, screw thread pair includes screw rod 6-1 and nut 6-2, and transmission support plate 3 arranges spiral shell
Bar 6-1, display device gripper shoe 1 arranges the nut 6-2 of cooperation.Screw rod 6-1 and nut 6-2 is all right
Exchange and arrange.
The specific design of gear drive as shown in Figure 1, Figure 2, Figure 4 shows, rotates regulation wheel 2 and is coaxially disposed
