[0030] Please refer to Figures 1 - 5, a portable projector, comprising: a base 1 and a support frame group 2. An installation block 11 is fixed on one side of the base 1. A handle 3 is installed on the installation block 11. The handle 3 is fixed to the installation block 11 by bolts. The handle 3 is fixed on one side of the object insertion hole. Carrying the projector through the handle 3 improves stability, control force and safety during the carrying process, reduces the risk of accidents, and the hand is in a natural and comfortable state when held, reducing hand fatigue caused by long-term use.

[0031] The support frame group 2 includes a first support frame 21 rotatably connected to the base 1. A circumferential rotating member 22 is arranged on the base 1. The rotating surface of the circumferential rotating member 22 is a horizontal plane. The circumferential rotating member 22 is rotatably connected to the lower end of the first support frame 21. The rotating surface of the circumferential rotating member 22 is perpendicular to the rotating surface of the first support frame 21. Through the circumferential rotating member 22, the support frame group 2 can rotate on the horizontal plane. The end of the first support frame 21 is rotatably connected to a second support frame 23. The end of the second support frame 23 is connected to an adapter 24. A third support frame 25 is connected to the adapter 24. A camera group 4 is connected to the third support frame 25. As Figure 2 and Figure 3 shown, when the support frame group 2 is in the unfolded state, the first support frame 21 supports the second support frame 23, making the second support frame 23 higher. The rotating surface of the second support frame 23 on the first support frame 21 is parallel to the rotating surface of the first support frame 21. The adapter 24 can rotate at the end of the second support frame 23, and the rotating surface overlaps with the second support frame 23. The rotating surface of the third support frame 25 on the adapter 24 is perpendicular to the adapter 24. Through the support frame group 2, the position of the camera group 4 can be adjusted as needed. When folding, the third support frame 25 needs to be rotated 180 degrees, then the second support frame 23 is rotated to be consistent with the first support frame 21, and finally they are rotated downward together.

[0032] A locking mechanism 5 is arranged on the side surface of the base 1 close to the first support frame 21. The locking mechanism 5 is used to lock the folded and stored support frame group 2 to prevent the support frame group 2 from unfolding during the carrying process. The locking mechanism 5 includes an elastic locking member 51. A locking groove 211 is opened at the rotating part of the first support frame 21. The locking mechanism 5 further includes a mounting plate 52. A flip plate 53 is rotatably connected to the mounting plate 52. The flip plate 53 is connected to the elastic locking member 51.

[0033] The elastic locking member 51 includes a locking rod 511. The locking rod 511 passes through the flip plate 53 and is connected to a pull plate 54. The pull plate 54 facilitates the operation of the flip plate 53. A spring 512 is sleeved on the locking rod 511. The spring 512 makes the locking rod 511 stably inserted into the locking groove 211, making the first support frame 21 stable. The two ends of the spring 512 are respectively connected to the locking rod 511 and the flip plate 53.

[0034] The mounting plate 52 is provided with a storage opening 521, and the storage opening 521 is longitudinally offset from the first locking groove 211. When the first locking rod 511 is turned upward, it contacts the first bracket 21. The mounting plate 52 is provided with a limiting groove 522, and the limiting groove 522 communicates with the storage opening 521. A shaft rod 55 is fixed in the limiting groove 522, and the turning plate 53 is slidably connected to the shaft rod 55. After the turning plate 53 is turned, it moves on the shaft rod 55 and then enters the limiting groove 522.

[0035] Elastic pieces 56 that abut against the side surface of the turning plate 53 are fixed on the inner wall of the storage opening 521. The elastic pieces 56 are symmetrically arranged. The turning plate 53 is turned downward to be fixed on the storage opening 521 by squeezing the elastic pieces 56. The stored turning plate 53 is stabilized by the elastic pieces 56, and no additional side operation is required.

[0036] An elastic locking member II 57 is connected to the turning plate 53. The elastic locking member II 57 includes a locking rod II 571. A second locking groove 41 is provided on the outer shell of the camera group 4. The locking rod II 571 passes through the turning plate 53 and is connected to the pulling plate 54. A second spring 572 is sleeved on the locking rod II 571, and the two ends of the second spring 572 are respectively connected to the first locking rod 511 and the turning plate 53.

[0037] A support plate 6 is fixed on the base 1, and the support plate 6 supports the first bracket 21, so that the first locking groove 211 and the second locking groove 41 are at the same height as the upward-turned first locking rod 511 and the second locking rod 571.

[0038] During use, first fold the support frame group 2. When the first bracket 21 contacts the support plate 6 and stops, then turn the turning plate 53 upward. When the turning plate 53 contacts the mounting plate 52 and stops. During this process, the first locking rod 511 first contacts the first bracket 21 and then is squeezed, so that the first locking rod 511 slides on the mounting plate 52, and the first spring 512 is compressed. And the second locking rod 571 first contacts the outer shell of the camera group 4 and then is squeezed, so that the second locking rod 571 slides on the mounting plate 52, and the first spring 512 is compressed. The first locking rod 511 and the second locking rod 571 respectively contact the first bracket 21 and the outer shell of the camera group 4 at the same time. After being turned upward, it then moves on the shaft rod 55 and enters the limiting groove 522. When the turning plate 53 stops moving, the first locking rod 511 enters the first locking groove 211 under the action of the first spring 512, and the second locking rod 571 enters the second locking groove 41 under the action of the second spring 572, thereby fixing the folded support frame group 2. Then hold the handle 3 to carry the projector, and the process is stable, and the support frame group 2 will not suddenly unfold. When the projector needs to be used, first pull the pulling plate 54 so that the first locking rod 511 and the second locking rod 571 respectively leave the first locking groove 211 and the second locking groove 41, and then perform storage by moving and rotating downward.

The objectives of the present utility model have been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments. Without departing from the said principles, any variations or modifications can be made to the embodiments of the present utility model.
