Description

Portable detachable holographic projector

technical field

The invention relates to a projection device capable of stereoscopically displaying three-dimensional images, in particular to a portable detachable holographic projector.

Background technique

At present, the known projectors are basically flat projectors, which are difficult to play three-dimensional images; and the projection devices capable of three-dimensional display of three-dimensional images are mostly fixed as a whole on the market, which is not easy to carry and disassemble. It is difficult to use in some special occasions, and it is not easy to disassemble and maintain.

Contents of the invention

In order to overcome the shortcomings of the existing projection devices for three-dimensional display of three-dimensional images that are not easy to carry and disassemble and maintain, the present invention provides a portable detachable holographic projector, which can not only display three-dimensional images three-dimensionally, but also conveniently Portable, easy to disassemble and maintain.

The technical solution adopted by the present invention to solve the technical problem is: a portable detachable holographic projector, including a base, a display, a control circuit module, a video player, and a square lens clip bracket, characterized in that:

The control circuit module and the video player are fixed on the base, and the display is connected to the hollow cavity of the base;

The square lens clip bracket is connected with the base through four linkage mechanisms respectively set at the four corners; the four sides of the square lens clip bracket are provided with slotted lens clips, and the lenses are inserted through the slotted lens clips; in the non-working state , the lens can be taken out, and the four link mechanisms drive the square lens clip bracket to be folded above the base; when in use, the square lens clip bracket is supported by the link mechanism, and then the lens is inserted.

The structure of the linkage mechanism: the lower end of the first connecting rod is hinged with the base through a female nail, the lower end of the second connecting rod is hinged with the upper end of the first connecting rod through a female nail, and the upper end of the second connecting rod is hinged through a female nail. The nail is hinged to the square lens clip bracket; a micro-adjustment structure is provided between the second connecting rod and the first connecting rod, and the micro-adjusting structure realizes the angle adjustment between the first connecting rod and the second connecting rod.

The beneficial effects of the invention are: the three-dimensional picture can be displayed three-dimensionally, it is easy to carry, easy to disassemble and maintain, and the structure is simple and easy to use.

Detailed ways

The portable detachable holographic projector shown in Figure 1 and Figure 2 includes a base 4, a display 11, a control circuit module 10, a video player 6, a square lens clip bracket 5, and the control circuit module 10 and the video player 6 are fixed. On the base 4, the display 11 is connected to the hollow cavity of the base; the square lens holder bracket 5 is connected with the base 4 through four linkage mechanisms 1 respectively arranged at four corners; the square lens holder bracket is provided with a slotted lens holder 3; In the non-working state, the four link mechanisms 1 drive the square lens clip bracket 5 to be folded above the base; when in use, the square lens clip bracket is supported by the link mechanism, inserted into the lens 9, and can be used through the remote control .

As shown in Figure 1, the structure of the linkage mechanism: the lower end 1a of the first connecting rod is hinged to the base 4 through a nail (there is a connecting rod support seat 8 on the base), and the lower end of the second connecting rod 1b is hinged through a nail The nail is hinged with the upper end of the first connecting rod 1a, and the upper end of the second connecting rod is hinged with the square lens holder bracket 5 through the female nail 2 (there is a connecting rod support seat 8 on the square lens holder bracket 5); the second connecting rod 1b and A micro-adjustment structure is provided between the first connecting rod 1a, and the micro-adjusting structure realizes the angle adjustment between the first connecting rod and the second connecting rod; through the micro-adjusting structure, the angle between the connecting rods can be made within a certain range Perform micro-adjustment, and then keep the square lens clip bracket 5 parallel to the display 11 .

As shown in Figure 1 and Figure 2, a structure of the micro-adjustment structure: it includes two micro-movement stoppers 7, and the micro-movement stoppers 7 are respectively screwed on the first connecting rod 1a and the second connecting rod 1b through screws, The support is realized by the surface of contact between the two fine movement stops 7 .

As shown in Figure 1 and Figure 2, by twisting the slotted lens holder 3, the angle between the lens 9 and the square lens holder bracket 5 can be finely adjusted within a certain range, so that the four lenses 9 can be combined more closely .

As shown in Figures 1 and 2, the slotted lens holder 3, the lens 9, and the square lens holder bracket 5 are combined into the first part, wherein the lens can be removed from the slotted lens holder; 2. The fine-tuning block 7 is combined into the second part, wherein the link mechanism 1 is foldable; the video player 6, the display 11, the base 4, and the control circuit module 10 are combined into the third part, and the first part and the third part pass through the second part. Partially connected, the holographic projector can be detachable, folded and portable, and conveniently controlled.
