Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1 and 2, a portable projector capable of adjusting the height of a projected image includes a projector main body 10 and a base 20, and an adjusting mechanism 30 is disposed between the projector main body 10 and the base 20.
The projector main body 10 can be placed at a desired position through the base 20, the height of the projector main body 10 can be adjusted by the first rotating shaft 31 and the supporting plate 33 of the adjusting mechanism 30, and the supporting plate 33 is rotated toward the side away from the placing groove 21, so that the supporting plate 33 is in an inclined or upright state, thereby increasing the height of the projector main body 10; then, by rotating the projector main body 10, the rotating base 11 and the second rotating shaft 32 are rotated, so that the projector main body 10 is kept in a horizontal or inclined state, and the height of the picture projected by the projector main body 10 is adjusted.
For example, when the projector body 10 is inclined, the height of the projected image is higher than that of the projected image in a horizontal state, so that people can adjust the image projected by the projector to a proper height, and people can watch the image better.
When people do not need to use the projector main body 10, the supporting plate 33 can be rotated towards the placing groove 21, the supporting plate 33 is contained in the placing groove 21, the rotating seat 11 below the projector main body 10 is also contained in the placing groove 21, the projector main body 10 is attached to the surface of the base 20, and the purposes of being small and exquisite and convenient to carry are achieved.
In the above scheme, the non-slip pad 22 is disposed on one side of the base 20 away from the projector main body 10, and the non-slip pad 22 improves the friction force between the base 20 and the contact surface, so as to prevent the base 20 and the contact surface from sliding, resulting in the deviation of the picture projected by the projector main body 10, and prevent the base 20 from accidentally dropping due to sliding.
And still be equipped with magnet 23 structure in base 20 inside, people can fix base 20 absorption on metal material's rack, play the fixed effect better, avoid taking place the condition that drops.
In the above scheme, first pivot 31 and second pivot 32 all adopt the damping pivot to people can rotate backup pad 33 and projecting apparatus main part 10 to arbitrary angle and fix better, adjust projecting apparatus main part 10 better.
