Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-5As shown, this utility model provides an adjustable-angle portable high-definition projector stand, including a support column 2, a support base 20 fixedly connected to the top of the support column 2, a rotating frame 21 movably connected to the middle end of the support base 20 via a bearing, a support platform 1 fixedly connected to the top of the rotating frame 21, a movable sleeve 7 slidably connected to the lower end of the support column 2, and three support rods 8 hinged to the lower end of the movable sleeve 7 via a pin. A fixed base 9 is fixedly connected to the bottom of the support column 2, and a pull rod 10 is hinged between the middle end of the support rod 8 and the surface of the fixed base 9 via a pin. A through groove 11 is provided, and a threaded hole 15 is provided at the upper end of the through groove 11. Insertion holes 19 are provided at the lower ends of both sides of the through groove 11. Rotating blocks 18 are movably connected to the surface of the insertion holes 19. A rotating sleeve 12 is fixedly connected between the two rotating blocks 18 on their sides that are close to each other. An anchor rod 13 is movably inserted into the inner cavity of the rotating sleeve 12. A connecting plate 14 is fixedly connected to the top of the anchor rod 13. The surface of the connecting plate 14 contacts the surface of the through groove 11. A locking bolt 16 is movably inserted into the upper end of the connecting plate 14. The surface of the locking bolt 16 is threadedly connected to the surface of the threaded hole 15.

[0024] In this technical solution, the support platform 1, rotating frame 21, support base 20, and pillar 2 facilitate the support and use of the high-definition projector during outdoor camping. The movable sleeve 7, support rods 8, pull rods 10, and fixed base 9 allow the three sets of support rods 8 and pull rods 10 to extend outwards when the movable sleeve 7 is pushed down, forming a three-point support under the pillar 2, reducing the chance of tipping over during use. Furthermore, when the bracket needs to be anchored to grass or lawn soil during outdoor camping, the locking bolt 16 can be rotated to secure it. After the threaded hole 15 is disengaged, personnel can pull the connecting plate 14 and the anchor rod 13 to move them. This causes the anchor rod 13 to rotate along the surface of the insertion hole 19, until the rotating sleeve 12 and the anchor rod 13 are perpendicular to the ground. Then, by pushing the anchor rod 13 downwards, it moves downwards along the inner cavity of the rotating sleeve 12, allowing the anchor rod 13 to be inserted into the soil. This effectively anchors the support rod 8 to the ground, preventing the entire unit from tipping over due to collisions during use and facilitating its operation.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 4As shown, the bottom of the support platform 1 is movably connected to the two ends of the first screw 22 via bearings. The surface of the first screw 22 is threadedly connected to the U-shaped clamping frame 4. The support platform 1 is fixedly connected to the four sides of the support platform 1. The surface of the U-shaped clamping frame 4 is slidably connected to the surface of the guide slide rod 3. Rubber anti-slip pads are pasted on both ends of the two U-shaped clamping frames 4 that are close to each other.

[0027] In this technical solution, the first screw 22 and the U-shaped clamp 4 facilitate personnel to clamp and fix the high-definition projector placed on the top of the support platform 1 on both sides, preventing the high-definition projector from falling off the top of the support platform 1. The guide slide rod 3 guides the U-shaped clamp 4, preventing it from tilting during movement. The rubber anti-slip pad effectively improves the anti-slip effect between the U-shaped clamp 4 and the high-definition projector.

[0028] Example 3:

[0029] Based on Embodiment 1, this utility model is as follows: Figure 5 As shown, the lower right end of the rotating frame 21 is movably connected to a second screw 25 via a bearing. The left end of the second screw 25 is threadedly connected to an L-shaped pin 26. The middle end of the rotating frame 21 is fixedly connected to a guide crossbar 24. The middle end of the L-shaped pin 26 is slidably connected to the surface of the guide crossbar 24. The upper end of the support base 20 is provided with pin holes 23. The upper end of the L-shaped pin 26 is movably connected to the surface of the pin holes 23. There are nine pin holes 23.

[0030] In this technical solution, the second screw 25, L-shaped pin 26, and pin hole 23 are used to limit the movement between the rotating frame 21 and the support base 20. When the operator needs to adjust the support angle of the support platform 1, the second screw 25 is rotated to move the L-shaped pin 26 to the right until the L-shaped pin 26 can disengage from the surface of the pin hole 23. Then, the operator can push the support platform 1 and the rotating frame 21 to rotate, thus facilitating the adjustment of the support angle of the support platform 1 according to the operator's needs. The guide bar 24 is used to guide the L-shaped pin 26 and prevent it from rotating during movement.

[0031] Example 4:

[0032] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, reinforcing strips 17 are fixedly connected to the lower ends of both sides of the support rod 8, a locking hole 5 is opened on the right side of the support rod 2, and an adjusting bolt 6 is threadedly connected to the right side of the movable sleeve 7.

[0033] In this technical solution, the lower ends of both sides of the support rod 8 are reinforced by the setting of the reinforcing strip 17, so as to avoid the through groove 11 from affecting the strength of the support rod 8. The locking hole 5 and the adjusting bolt 6 make it easy for personnel to fix the movable sleeve 7.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.
