[0002] A holographic projection device is a high-tech device that can produce three-dimensional stereoscopic images. It uses a laser light source to record the hologram of an object, and then reproduces the recorded hologram as a three-dimensional image through the principles of interference and diffraction. Among them, small holographic projection devices are widely used, and are widely used in entertainment and art holographic projection, education or medical holographic projection, etc.

[0003] A small holographic projection device is generally composed of a projection main shell and a bracket body. The small projection main shell is an overall square structure. Lasers, beam splitters, scattering screens, interferometers, controllers, image processors and other structures are arranged inside the projection main shell.

[0006] Moreover, the existing small-sized holographic projection device support body has a relatively low structural stability after overall assembly.

[0007] In addition, the existing small holographic projection device support body has low mobility.

[0008] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-5 , a convenient assembly type holographic projection bracket, including a bracket cross tube 1, a longitudinal tube body 11 is provided at both ends of the bracket cross tube 1, a moving wheel 12 is provided on the longitudinal tube body 11, a side support plate 2 and a socket 4 are provided on the bracket cross tube 1, a supporting slot 3 is provided on the bracket cross tube 1 and the side support plate 2, a locking bolt 41 and a plug-in slot 42 are provided on the socket 4, a middle bracket 5 is inserted in the plug-in slot 42, a plug-in support plate 51 and a clamping bolt 52 are provided on the middle bracket 5, a locking slot 53 and a sliding square hole 54 are provided on the middle bracket 5, a telescopic bracket 6 is slidably connected in the sliding square hole 54, a mounting plate 7 and a top support plate 62 are provided on the telescopic bracket 6, and a positioning hole 61 is provided on the telescopic bracket 6. The small holographic projection device recorded in this patent is a prior art and is not drawn.

[0030] In detail, there are two longitudinal tubes 11 that are symmetrical on the left and right and are respectively welded and fixed to the two ends of the bracket cross tube 1. There are four symmetrically arranged movable wheels 12 that are respectively arranged at the lower ends of the longitudinal tube 11. The movable wheels 12 are universal brake wheels, and their wheel body brackets are made of stainless steel 304, with high supporting strength and no deformation.

[0031] Furthermore, the locking bolt 41 is threadedly connected to the socket 4, and the locking bolt 41 and the locking groove 53 are a group, which are two groups symmetrical on the left and right. When the two locking bolts 41 are inserted into the locking groove 53, the assembly stability of the middle bracket 5 and the socket 4 is improved.

[0032] Furthermore, the clamping bolt 52 is threadedly connected to the middle bracket 5, and the positioning holes 61 are twelve arranged vertically, so that the telescopic bracket 6 can slide vertically up and down and be stably positioned through the positioning holes 61 and the clamping bolts 52, thereby realizing convenient vertical height adjustment of the small holographic projection device on the mounting plate 7.

[0033] In more detail, the plug-in tray 51 is provided with an avoidance opening 511 , and when the four plug-in trays 51 are inserted into the corresponding four supporting slots 3 , the avoidance opening 511 can prevent the plug-in trays 51 from colliding with the outer wall of the socket 4 .

[0034] The plug-in support plate 51 and the top support plate 62 are both triangular structures and are four in a circular arrangement. The triangular structure has excellent stability, and the plug-in support plate 51 and the top support plate 62 are both made of high-quality hard alloy steel, with high supporting strength, no deformation, corrosion resistance, wear resistance, and long service life.

[0035] In general, a damping layer 31 is provided in the inner groove of the supporting slot 3. The damping layer 31 is evenly coated along the inner groove wall of the supporting slot 3. The damping layer 31 is a silicone rubber coating. The top cross-section of the supporting slot 3 is a long strip-shaped inner groove. When the four plug-in trays 51 are inserted into the corresponding four supporting slots 3, the four plug-in trays 51 will be squeezed and contacted with the damping layer 31. The silicone rubber coating has excellent elastic damping friction, which improves the overall stability and anti-slip properties of the plug-in tray 51 when inserted into the supporting slot 3.

[0036] Finally, the top supporting plate 62 is provided with mounting holes 71 , and there are four mounting holes 71 symmetrically arranged. The four mounting holes 71 combined with the preset mounting bolt structure improve the installation stability of the small holographic projection device as a whole.

[0037] Working method: During installation, first insert the middle bracket 5 into the plug-in slot 42, then rotate the locking bolt 41 clockwise until the locking bolt 41 is driven to snap into the locking slot 53 through thread transmission, then insert the telescopic bracket 6 into the sliding square hole 54, then rotate the clamping bolt 52 clockwise, and drive the clamping bolt 52 to snap into one of the positioning holes 61 through thread transmission, and the convenient installation of the bracket body can be completed. Later, the small holographic projection device can be fixed on the mounting plate 7 through the preset mounting bolts and mounting holes 71 and can be powered on for use. When it needs to be disassembled and transported later, first remove the small holographic projection device from the mounting plate 7 and pack it into a preset packaging box, and then disassemble the bracket cross tube 1, the middle bracket 5, and the telescopic bracket 6 as a whole, and then pack them independently and transfer them to the preset packaging box, which is convenient for later transportation, and overall improves the convenient assembly, storage and transportation of the bracket body for the small holographic projection device.

[0038] Moreover, when the middle bracket 5 is inserted into the plug-in slot 42 and locked and installed by the locking bolt 41, the four plug-in support plates 51 will be inserted into the corresponding four supporting slots 3, which improves the assembly structure stability between the middle bracket 5 and the bracket cross tube 1. At the same time, the four top supporting plates 62 arranged on the upper part also further improve the structural stability between the telescopic bracket 6 and the mounting plate 7, thereby improving the overall structural stability of the bracket body for the small holographic projection device after the overall assembly.

[0039] In addition, after the whole assembly of the bracket body is completed, the preset brake on the moving wheel 12 is loosened, and the bracket body can be pushed to achieve flexible movement to the required position, and then the preset brake on the moving wheel 12 can be braked, thereby improving the flexibility and mobility of the bracket body.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
