[0030] As Figures 1-6 shown, in this embodiment, a projection bracket applicable to the visual scene construction of an aviation simulator system is also disclosed. Its main structure includes a mounting plate 1, and the mounting plate 1 is sequentially connected with a telescopic tube 2, a first rotary connecting member 3, a first corner member 4, a second rotary connecting member 5, a support 6, a second corner member 7, a deflection assembly 8 and a tray 9 for mounting a projector;

[0031] The connection method between the first rotary connecting member 3 and the first corner member 4, between the first corner member 4 and the second rotary connecting member 5, between the second corner member 7 and the deflection assembly 8, and between the deflection assembly 8 and the tray 9 is the same as the connection method between the first connecting member and the second connecting member.

[0032] Specifically, the mounting plate 1 can be mounted on a stable plane, such as: a moving carrier, the ground, a wall and a ceiling;

[0033] One end of the first rotary connecting member 3 is fixed to the telescopic tube 2, the other end of the first rotary connecting member 3 is bolted to the first corner member 4, and the first rotary connecting member 3 and the first corner member 4 are connected by end face teeth engagement; one end of the second rotary connecting member 5 is fixed to the support 6, the other end of the second rotary connecting member 5 is bolted to the first corner member 4, and the second rotary connecting member 5 and the first corner member 4 are connected by end face teeth engagement; the first rotary connecting member 3 and the second rotary connecting member 5 can have the same structure, both are cylindrical, and a through threaded hole is provided at the axis position for cooperating with a connecting bolt to lock or loosen the first rotary connecting member 3 and the first corner member 4, and the second rotary connecting member 5 and the first corner member 4. A convex ring for abutting and limiting is provided on its outer wall to play a role in positioning and installation. The end faces of the first rotary connecting member 3 and the second rotary connecting member 5 connected to the first corner member 4 are both convex conical and provided with end face teeth; the first corner member 4 is used to change the extension direction of the bracket. In this embodiment, the connection ends of the first corner member 4 face perpendicular to each other, and their connection end faces are both concave conical and provided with end face teeth; when the direction needs to be rotated and adjusted, loosen the connecting bolt, and the end face teeth engagement can be released to achieve rotation. After rotating to the appropriate position, screw the bolt to tighten and lock.

[0034] One end of the second corner fitting 7 is fixed to the carrier 6. The second corner fitting 7 is bolted to the deflection assembly 8, and the second corner fitting 7 and the deflection assembly 8 are connected by end face teeth in meshing connection. Specifically, one end of the second corner fitting 7 is inserted into the carrier 6 and fastened by bolts. The other end is used for plugging and mating with the deflection assembly 8. The end face of the second corner fitting 7 where it is connected to the deflection assembly 8 is concave-conical and is provided with end face teeth. The carrier 6 mainly plays a role of supporting and connecting and can be replaced with different lengths according to requirements. When it is necessary to rotate and adjust the direction, loosen the connecting bolts, then the meshing of the end face teeth can be released to achieve rotation. After rotating to the appropriate position, tighten the bolts to lock.

[0035] The deflection assembly 8 is mainly used to realize the adjustment of the deflection inclination angle of the projector. The tray 9 is composed of a flat support part for connecting the projector and a rotary connection part for connecting the deflection assembly 8.

[0036] It should be noted that through the settings of the telescopic tube 2, the first corner fitting 4 and the second corner fitting 7, the bracket can adjust the height / length and angle according to different space requirements, is applicable to the installation requirements and environments of different projection devices, and meets the personalized needs of users. At the same time, through the settings of the first rotary connector 3, the second rotary connector 5 and the deflection assembly 8, the bracket can realize multi-directional rotation and deflection. The user can easily adjust the picture position during projection to ensure the best projection effect, thus realizing large-range adjustment of the projector.

[0037] In addition, the connection method of end face teeth meshing enhances the bonding strength between components, improves the stability of the overall bracket, reduces the displacement risk of the projector caused by vibration or gravity during use, ensures the accuracy of projection, and thus effectively reduces the adjustment frequency and maintenance cost of the projector's projection imaging.

[0038] Furthermore, in specific implementation, as Figures 3-5 shown, in the above-mentioned deflection assembly 8 provided by the embodiment of the present utility model, it includes a first deflector 81 and a second deflector 82. The first deflector 81 is bolted to the second corner fitting 7. One end of the second deflector 82 is rotatably connected to the first deflector 81, and the other end of the second deflector 82 is rotatably connected to the tray 9. Preferably, the active deflection surface of the second deflector 82 and the active deflection surface of the tray 9 are perpendicular to each other, so that the projector can be better adjusted in projections at different angles to adapt to the projection effects of different scenarios and requirements.

[0039] Preferably, the first deflector 81 includes a first fitting 811 and a first locking member 812, and the second deflector 82 includes a second fitting 821 and a second locking member 822; the same connection method between the first connecting member and the second connecting member is adopted between the second fitting 821 and the first fitting 811, between the second fitting 821 and the first locking member 812, between the tray 9 and the second fitting 821, and between the tray 9 and the second locking member 822; specifically, the first fitting 811 fastens the first locking member 812 with bolts to clamp and limit one end of the second fitting 821, and both between the second fitting 821 and the first fitting 811 and between the second fitting 821 and the first locking member 812 are connected by end face teeth meshing; the other end of the second fitting 821 fastens the second locking member 822 with bolts to clamp and limit the tray 9, and both between the tray 9 and the second fitting 821 and between the tray 9 and the second locking member 822 are connected by end face teeth meshing; the structural forms of the end of the first fitting 811 connected to the second corner member 7, the end of the first rotating connecting member 3 connected to the first corner member 4, and the end of the second rotating connecting member 5 connected to the first corner member 4 are the same, and similar functions of movable rotation and stable locking are achieved;

[0040] In addition, elastic members 83 are limitedly arranged between the first fitting 811 and the first locking member 812 and between the second fitting 821 and the second locking member 822; specifically, the elastic members 83 are limited by arranging limiting rings 84 between the first fitting 811 and the first locking member 812 and between the second fitting 821 and the second locking member 822. When the deflection angle needs to be adjusted, loosen the corresponding bolts. Under the action of the elastic members 83, the first locking member 812 and / or the second locking member 822 are pushed open, and the end face teeth meshing is released to perform deflection. When the appropriate deflection angle is reached, re-tighten the bolts to achieve fastening.

[0041] Furthermore, in specific implementation, such as Figure 1 、 2As shown in the figure, the telescopic tube 2 provided in the embodiment of the present invention includes an outer tube 21 and an inner tube 22. One end of the inner tube 22 is sleeved on the first rotating connector 3, and the other end of the inner tube 22 is connected with a locking component 23 that is movably clamped with the outer tube 21 for limiting the relative sliding of the inner tube 22. Specifically, the outer tube 21 is vertically welded to the center position of the mounting plate 1. A plurality of positioning holes 210 are axially formed in the outer tube 21. The locking component 23 includes a locking head 231 and a bolt 232. The locking head 231 is inserted into one end of the inner tube 22 and is bolted to the inner tube 22. The bolt 232 is elastically and movably arranged in the locking head 231 for cooperatively clamping the positioning hole 210. Two bolts 232 can be symmetrically arranged. The two bolts 232 are connected into one body by a spring and are limited in the locking head 231. In the natural state, the bolt 232 extends out of the locking head 231 and cooperatively inserts into the positioning hole 210 to play a clamping role and fix the relative position of the inner tube 22 and the outer tube 21. When adjustment is required, the bolt 232 is pressed to retract it into the locking head 231 to release the clamping of the outer tube 21, and the relative sliding of the inner tube 22 and the outer tube 21 can be realized, thereby realizing the telescoping of the telescopic tube 2. The bracket has good telescopic performance and stability. The locking component 23 can effectively limit the sliding of the inner tube 22, avoid unnecessary changes caused by external forces, and enhance the stability and safety of the bracket.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
