DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3, the present invention provides a technical solution: a stable projection device, including a base 1, a support foot 2 is fixedly installed at the bottom of the base 1, the number of support feet 2 is four, and they are distributed at the four corners of the bottom of the base 1. A rubber sleeve 16 is sleeved at the bottom of the support foot 2. The projection equipment can be stably placed through the support feet 2 fixedly installed at the bottom of the base 1. The number of support feet 2 being four makes the placement more stable, and the rubber sleeve 16 plays an anti-slip role. A first groove 3 is opened at the top of the base 1. A support column 4 is fixedly installed at the bottom of the inner wall of the first groove 3. A threaded hole 5 is opened at the top of the support column 4. A bolt 6 is inserted into the inner wall of the threaded hole 5. A rubber pad 7 is fixedly connected to the top of the bolt 6. A projector 8 is movably installed at the top of the base 1. The number of columns 4 is two, and they are symmetrically distributed with the vertical center line of the base 1 as the symmetry line. By adjusting the position of the bolt 6 in the inner wall of the threaded hole 5, the height of the bolt 6 can be adjusted, thereby adjusting the angle of the projector 8 in contact with the top of the bolt 6, which is convenient for obtaining a better projection effect. The two support columns 4 can stably support the projector 8, and the rubber pad 7 plays an anti-slip role and prevents the bottom of the projector 8 from being scratched. Clamping columns 9 are installed on both the left and right sides of the projector 8 at the top of the base 1. Guide columns 10 are movably installed on both the left and right sides of the base 1. Limit ribs 11 are fixedly installed above the guide columns 10 on both the left and right sides of the base 1. A spring 12 surrounding the surface of the limit rib 11 is fixedly connected between the inner side of the guide column 10 and the base 1. Clamping blocks 13 are movably installed on the front of the guide columns 10. Card slots 14 are opened on the inner sides of the clamping blocks 13. A limit rod 15 is fixedly installed at the top of the base 1. A rotating groove 17 is opened on the side of the clamping column 9 close to the projector 8. A vertical rod 18 is fixedly connected between the top and bottom of the inner wall of the rotating groove 17. A rotating rod 19 is sleeved on the surface of the vertical rod 18. A sponge pad 20 is sleeved at one end of the rotating rod 19 away from the vertical rod 18. The spring 12 is in a stretched state. The number of limit rods 15 is two, and they are symmetrically distributed with the vertical center line of the base 1 as the symmetry line. The height of the limit rod 15 is not less than 15 cm. By using the clamping column 9, the rotating groove 17, the vertical rod 18, the rotating rod 19, the guide column 10, the spring 12, the clamping block 13, the card slot 14 and the limit rib 11 in cooperation, the projection device can be well fixed, preventing the projection device from shaking during projection and reducing the projection effect. The limit rod 15 prevents the projector 8 from sliding backward when adjusting the angle. The spring 12 is in a stretched state and generates a pulling force on the guide column 10 due to restoring deformation, causing the clamping blocks 13 on the guide column 10 to close. The angle of the clamping block 13 is adjustable, so as to clamp the projector 8. The card slot 14 is stuck on the upper edge of the projector 8, and the fixing effect is better.

[0023] When in use, the projector 8 is adjusted to a suitable angle by adjusting the height of the bolt 6. The spring 12 is in a stretched state and generates a pulling force on the guide column 10 due to the recovery of deformation, so that the clamping block 13 on the guide column 10 is retracted. The angle of the clamping block 13 is adjusted so that the slot 14 is stuck on the upper edge of the projector 8. The rotating rod 19 is adjusted so that the rotating rod 19 supports the left and right sides of the projector 8. The limit rod 15 prevents the projector 8 from sliding backwards.

[0024] In summary, the projection device is stable in use. By using the clamping column 9, the rotating groove 17, the vertical rod 18, the rotating rod 19, the guide column 10, the spring 12, the clamping block 13, the card slot 14 and the limiting rib 11, the projection device can be well fixed to prevent the projection device from shaking during the projection process and reducing the projection effect. By using the supporting column 4, the threaded hole 5, the bolt 6 and the rubber pad 7 in combination, the height of the bolt 6 can be controlled by screwing out or screwing in the bolt 6, thereby adjusting the projection angle of the projector 8 placed on the rubber pad 7, so as to obtain a better projection effect.
