Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0023] Refer to Figure 1 As shown, a portable projector for information consultation provided by the present invention includes: a projector body 9. One side of the projector body 9 is provided with a column 2 for longitudinal support. The column 2 is provided with a liftable lifting member. The projector body 9 is arranged on one side of the lifting member, and the height of the projector body 9 is adjusted based on the lift.

[0024] Combined with Figure 2 As shown, the lifting member includes a connecting seat 4. A through hole 11 sleeved on the column 2 penetrates through the connecting seat 4. The outside of the connecting seat 4 is provided with a limiting member for height limitation, and one end of the limiting member abuts against the column 2.

[0025] In the above, when using the projector body 9, column 2, lifting member and projector body 9 of the present invention, the connecting seat 4 in the lifting member is lifted and adjusted on the column 2 through the through hole 11. When the height is adjusted to the predetermined height, the connecting seat 4 is restricted on the column 2 by the limiting member to prevent the connecting seat 4 from sliding down on the column 2, realizing that the device can be height-adjusted according to the use environment.

[0026] Furthermore, in order to facilitate keeping the column 2 always vertically placed, refer to Figure 1 As shown, a support plate 1 for support is further provided at the bottom of the column 2. The support plate 1 can increase the area of the bottom end of the column 2 in contact with the ground and prevent the column 2 from tipping over.

[0027] Furthermore, in order to facilitate fixing the height of the lifting of the connecting seat 4, refer to Figure 2As shown in the figure, the limiting member includes an adjusting bolt 3. A first threaded hole 10 penetrates inwardly through the outside of the connecting seat 4. The adjusting bolt 3 is threadedly connected through the first threaded hole 10, and one end of the adjusting bolt 3 abuts against the column 2. When the connecting seat 4 is adjusted to a predetermined height on the column 2, the adjusting bolt 3 is tightened so that one end of the adjusting bolt 3 abuts against the column 2, thereby preventing the connecting seat 4 from sliding on the column 2, and further fixing the height of the projector body 9.

[0028] In the present utility model, in combination Figure 3 As shown in the figure, on one side of the connecting seat 4 of the present embodiment, there is also a flipping mechanism for driving the projector body 9 to flip up and down. The flipping mechanism includes a rotating disk 5 and a rotating seat 6. The rotating disk 5 is arranged on the side wall of the connecting seat 4. A rotating groove for accommodating the rotation of the rotating seat 6 is provided on the side of the rotating disk 5 facing away from the connecting seat 4. The projector body 9 is detachably installed on the rotating seat 6.

[0029] As described above, when using the flipping mechanism provided by the present utility model, the rotating disk 5 provides an installation position for the rotation of the rotating seat 6 on the connecting seat 4, and the rotating seat 6 can rotate on the rotating disk 5 through the rotating groove, thereby facilitating the up and down flipping adjustment of the projector body 9.

[0030] Furthermore, in order to facilitate the fixing of the flipping angle of the projector body 9, referring to Figure 3-4 As shown in the figure, a plurality of first anti-slip teeth 13 are distributed in an annular array on the outer wall of the rotating seat 6, and a plurality of second anti-slip teeth 14 are distributed in an annular array on the inner wall of the rotating groove. The plurality of anti-slip teeth and the plurality of second anti-slip teeth 14 are distributed in a staggered manner in sequence. When the rotating seat 6 rotates, the first anti-slip teeth 13 cross over the second anti-slip teeth 14, thereby facilitating the rotation of the rotating seat 6 on the rotating disk 5. When the external force applied to the rotating seat 6 is cancelled, by the first anti-slip teeth 13 being stuck in the second anti-slip teeth 14, it is possible to prevent the rotating seat 6 from automatically rotating in the rotating groove, thereby facilitating the positioning and fixing of the flipping angle of the projector body 9.

[0031] Furthermore, in order to facilitate the rotational installation of the rotating seat 6 on the rotating disk 5, referring to Figure 3 As shown in the figure, an indented hole 17 penetrates through the center of the side of the rotating seat 6 facing away from the rotating disk 5. A third threaded hole 15 aligned with the indented hole 17 is provided at the center of the rotating groove. A connecting bolt 16 for connection is provided between the indented hole 17 and the third threaded hole 15. The rotating seat 6 is rotatably installed on the connecting bolt 16. Place the rotating seat 6 in the rotating groove. At this time, the indented hole 17 on the rotating seat 6 is aligned with the third threaded hole 15. Screw the connecting bolt 16 from the indented hole 17 into the third threaded hole 15. At this time, the rotating seat 6 is detachably and rotatably installed in the rotating groove.

[0032] Further, for the convenience of detachably mounting the projector body 9 on the rotating base 6, refer to Figure 3 As shown, a fixing member 8 is provided on the side of the rotating base 6 facing away from the rotating disc 5. Second threaded holes 12 extending into the rotating base 6 are formed at both ends of the fixing member 8. A fixing bolt 7 connecting the fixing member 8 and the rotating base 6 is provided in the second threaded hole 12. An installation area for mounting the projector body 9 is formed between the fixing member 8 and the rotating base 6. Place the projector body 9 on the rotating base 6. At this time, place the fixing member 8 outside the projector body 9 and align the second threaded holes 12 on the fixing member 8 with the second threaded holes 12 on the rotating base 6. Install the fixing bolt 7 in the second threaded hole 12, thereby fixing the fixing member 8 on the rotating base 6, and further detachably mounting the projector body 9 on the rotating base 6.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
