[0020] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the utility model.

[0021] The folding computer projector is convenient to carry, and refers to Figures 1-3, including the projector body 1 and the support plate 2 connected with the bottom of the projector body 1 through a hinge. This hinge connection mode enables the projector body 1 to rotate flexibly relative to the support plate 2, laying a foundation for subsequent angle adjustment.

[0022] One end of the support plate 2 is movably inserted with a crossbar 3, and a spring 7 is sleeved on the crossbar 3. The spring 7 enables the crossbar 3 to have a tendency to move towards the connection between the projector body 1 and the support plate 2, thereby providing stable elastic support for the entire adjusting mechanism.

[0023] One end of the crossbar 3 is rotatably installed with an L-shaped plate 4, and the bottom edge of the projector body 1 is symmetrically and fixedly installed with two guide rails 5. The top of the L-shaped plate 4 is slidably inserted into the two guide rails 5. Through the sliding cooperation of the L-shaped plate 4 and the guide rails 5, as well as the synergistic effect of the crossbar 3 and the spring 7, the user can easily push or pull the L-shaped plate 4 to move in the guide rails 5, thereby changing the included angle between the support plate 2 and the projector body 1 and realizing the adjustment of the projection angle of the projector.

[0024] The lower surface of the projector body 1 is fixedly installed with a plurality of downward protruding arc-shaped blocks 6 at equal intervals. The closest distance between the arc-shaped blocks 6 and the inner wall of the bottom of the guide rail 5 is greater than or equal to the thickness of the top of the L-shaped plate 4, so as to ensure that the L-shaped plate 4 can slide in the guide rail 5 without being hindered by the arc-shaped blocks 6. The top arc surface of the arc-shaped block 6 abuts against the upper surface of the L-shaped plate 4, so as to exert a downward oblique force on the L-shaped plate 4 and improve the stability. The top edge of the L-shaped plate 4 abuts against the bottom arc surface of the upper adjacent arc-shaped block 6 and the connection between the lower surface of the projector body 1, so as to prevent the L-shaped plate 4 from moving excessively. This ingenious contact design utilizes the guiding characteristics of the arc surface to make the L-shaped plate 4 move more smoothly during the movement, and on the other hand, the arc-shaped blocks 6 also play a limiting role, ensuring the stability and reliability of the entire adjusting process, so that the projector can maintain a good supporting state at different angles.

[0025] Further, the arc-shaped blocks 6 are distributed along the length direction of the guide rail 5, and the width of the arc-shaped blocks 6 is equal to the width of the guide rail 5. This design enables the arc-shaped blocks 6 to better cooperate with the guide rail 5, providing omnidirectional guidance and support for the L-shaped plate 4, thereby enhancing the stability and reliability of the angle adjustment.

[0026] With reference to Figure 4 When the support plate 2 and the L-shaped plate 4 are in the state of being attached to the projector body 1, the L-shaped plate 4 covers the lens of the projector body 1. This not only protects the lens and other key parts of the projector body 1 from being collided or scratched during carrying, but also makes the appearance of the entire projector more neat and beautiful.

[0027] The support plate 2 and the L-shaped plate 4 are in a horizontal state, the lower surfaces of the support plate 2 and the L-shaped plate 4 are flush with the lower surface of the guide rail 5, the design detail guarantees portability and also considers the stability of the projector when placed, when the projector needs to be temporarily placed on a plane, the flat lower surface can make it stand stably and not easily fall down.

[0028] The width of the support plate 2 is equal to the minimum spacing between the two guide rails 5, and the bottom of the support plate 2 is provided with anti-skid lines, the equal width design makes the whole structure more compact, and the anti-skid lines increase the friction between the support plate 2 and the supporting surface, whether adjusting the angle when in use or placing on a desktop or the like plane, the projector can be effectively prevented from sliding, further improving the safety and stability of use.

[0029] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications shall belong to the protection scope of the utility model.
