DETAILED DESCRIPTION

[0019] See also Figures 1 to 6A projector for a multimedia exhibition hall is shown, comprising a projector body 11, a mounting ring 12 is provided on the upper side of the projector body 11, two fixing blocks 15 are provided on the inner wall of the mounting ring 12, a supporting arc rod 16 is fixedly provided on one side of the fixing block 15, slots 19 are provided on both sides of the mounting ring 12, a connecting component 17 is provided in the mounting ring 12, a mounting plate 18 is provided on one side of the connecting component 17, and the mounting plate 18 is fixedly provided on the top of the projector body 11; the connecting component 17 can be locked with the mounting ring 12, so that the projector body 11 is stably installed on the lower side of the mounting ring 12.

[0020] Furthermore, the connecting assembly 17 includes a connecting plate 22, which is arranged on one side of the mounting plate 18, and a connecting column 27 is connected between the mounting plate 18 and the connecting plate 22. Support rods 23 are provided on the front and rear sides of the connecting plate 22, and arc holes 24 corresponding to the supporting arc rods 16 are provided on the support rods 23, and the supporting arc rods 16 pass through the corresponding arc holes 24; when the supporting arc rods 16 are inserted into the arc holes 24, the supporting arc rods 16 suspend the connecting assembly 17 in the mounting ring 12, so that the projector body 11 can be stably installed on the lower side of the mounting ring 12; the positions of the fixing block 15 and the supporting arc rod 16 on one side of the mounting ring 12 are determined by rotating the fixing block 15 and the supporting arc rod 16 on the other side by 180 degrees, so that when the connecting plate 22 is rotated, the arc holes 24 on the two support rods 23 can be separated from the supporting arc rods 16 on both sides of the mounting ring 12 at the same time.

[0021] Furthermore, a cylindrical rod 25 is provided on both sides of the connecting plate 22, and an insertion rod 26 is slidably provided inside the cylindrical rod 25. A spring is connected between the insertion rod 26 and the cylindrical rod 25, and the insertion rod 26 is plugged into the corresponding slot 19; when the insertion rod 26 is inserted into the slot 19, the connecting assembly 17 cannot rotate, thereby ensuring the stable installation of the projector body 11.

[0022] Furthermore, a push plate 20 is slidably provided in the slot 19, and a push rod 21 is provided on one side of the slot 19, and the push rod 21 passes through the side wall of the slot 19 and is connected to the push plate 20; pushing the push rod 21 causes the push plate 20 to move, thereby pushing the end of the insertion rod 26 out of the slot 19, and then the connecting component 17 can be rotated.

[0023] Furthermore, a mounting plate 13 is provided on the top of the mounting ring 12, and a plurality of mounting holes 14 are provided in a circular shape at equal intervals on the mounting plate 13; the mounting plate 13 can be installed on the ceiling of the exhibition hall by means of bolts, so that the mounting plate 13 and the mounting ring 12 are fixed on the ceiling, and the projector body 11 can be detachably installed by means of a connecting assembly 17.

[0024] The working principle of the utility model is that when the projector body 11 is disassembled for maintenance, the push rod 21 is pressed to move the push plate 20, so that the push plate 20 pushes the plug rod 26 out of the slot 19, and then the projector body 11 is rotated to rotate the connecting plate 22, so that the bracket rod 23 rotates accordingly, so that the supporting arc rod 16 is separated from the arc hole 24, so that the lock between the connecting component 17 and the mounting ring 12 is released, and then the connecting component 17 and the projector body 11 are taken away together to remove the projector body 11 from the ceiling, and then the projector body can be repaired. 11 for maintenance; after the maintenance is completed, the connecting assembly 17 is extended into the mounting ring 12, so that the bracket rod 23 is located on one side of the end of the supporting arc rod 16, and the insertion rod 26 is against the inner wall of the mounting ring 12, and then the projector body 11 is rotated to rotate the connecting plate 22 and the bracket rod 23, so that the supporting arc rod 16 is inserted into the arc hole 24, and when it is rotated until the insertion rod 26 is aligned with the slot 19, the insertion rod 26 is inserted into the slot 19 under the action of the spring, and the connecting assembly 17 is locked with the mounting ring 12 again, so that the projector body 11 is re-installed on the ceiling of the exhibition hall.

[0025] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
