DETAILED DESCRIPTION

[0027] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a projector that is easy to maintain, including a body 1, a top end surface of the body 1 is provided with a connecting assembly, the connecting assembly includes a connecting piece 2, a mounting plate 3, a movable plate 4, a fastening bolt 5, a male head 6, a female head 7, a clamping block 8, a spring 9, a rotating shaft 10, a stopper 11, a coil spring 12, a slide groove 13, a sliding plate 14, a connecting rod 15, a toggle piece 16, a rubber ring 17, and a groove 18.

[0028] In one embodiment of the utility model, the top end surface of the body 1 is fixedly connected with a connecting member 2 by bolts, and the top end surface of the connecting member 2 is fixedly connected with a mounting plate 3, the mounting plate 3 is plugged with the movable plate 4, the movable plate 4 is sleeved with the fastening bolts 5, and the fastening bolts 5 are threadedly connected with the mounting plate 3. By screwing the fastening bolts 5, the fastening bolts 5 are tightened, and then the mounting plate 3 and the movable plate 4 are fixed together, and the top end surface of the movable plate 4 is fixedly connected with a male head 6, the male head 6 is clamped with the female head 7, and the inner top surface of the female head 7 is provided with a mounting groove, and the inner wall of the mounting groove is hinged with a clamping block 8, and the number of the clamping blocks 8 is provided in two groups, and the two groups of clamping blocks 8 are symmetrically arranged on both sides of the female head 7, and the top end surface of the clamping block 8 is fixedly connected with a spring 9, and the end of the spring 9 away from the clamping block 8 is fixed to the inner top surface of the mounting groove. Connection, a through hole is provided on the top end face of the male head 6, and a rotating shaft 10 is rotatably connected to the inner wall of the through hole, and a stopper 11 is fixedly connected to the side wall of the rotating shaft 10, and a coil spring 12 is fixedly connected to the side wall of the rotating shaft 10, and the end of the coil spring 12 away from the rotating shaft 10 is fixedly connected to the inner wall of the male head 6, and the coil spring 12 elastically pulls the rotating shaft 10 and the stopper 11 so that the stopper 11 is flush with the top of the male head 6, and a sliding groove 13 is provided on the inner wall of the through hole, and the sliding groove 13 is slidingly connected to the sliding plate 14, and a connecting rod 15 is fixedly connected to the bottom end face of the sliding plate 14, and a toggle piece 16 is fixedly connected to the top end face of the male head 6, and a groove 18 is provided on the bottom end face of the female head 7, and the groove 18 is arranged in an annular shape, and the groove 18 is adapted to the rubber ring 17.

[0029] When the machine body 1 needs to be disassembled for maintenance, the toggle piece 16 is pulled outward, so that the toggle piece 16 drives the connecting rod 15 and the sliding plate 14 to move, and the sliding plate 14 pushes the stopper 11 and the block 8 upward, and the block 8 is disconnected from the through hole. At this time, the machine body 1 is rotated to cancel the connection between the male head 6 and the female head 7, and the disassembly of the machine body 1 can be completed. After the machine body 1 is maintained, the machine body 1 is rotated in the opposite direction to disconnect the male head 6 and the female head 7. At this time, the block 8 moves to the top of the through hole, and the block 8 pushes the block 8 under the elastic action of the spring 9, so that the block 8 is connected to the through hole, thereby locking the installation component to avoid accidental rotation of the male head 6 and causing the machine body 1 to fall accidentally. At the same time, the fastening bolt 5 is loosened, and the machine body 1 can be rotated at this time to adjust the machine body 1 to a suitable angle, and then the fastening bolt 5 is tightened again to fix the pitch angle of the machine body 1.

[0030] In addition, a rubber ring 17 is fixedly connected to the top end face of the male head 6, and a groove 18 is provided on the bottom end face of the female head 7. The groove 18 is arranged in a ring shape and is matched with the rubber ring 17. The rubber ring 17 is arranged to fill the gap between the male head 6 and the female head 7 to prevent the male head 6 and the female head 7 from shaking. At the same time, the rubber ring 17 increases the force required to rotate the male head 6, prevents the body 1 from falling due to misoperation, and improves the stability and reliability of the connecting component.

[0031] In the utility model, when in use, the installation and disassembly of the body 1 can be completed by rotating the body 1. When installing the body 1, the block 8 is engaged with the through hole, and the body 1 cannot rotate normally. By moving the sliding plate 14 and pushing the block 8 upward, the body 1 can be rotated to complete the disassembly of the body 1. When the fastening bolts 5 are loose, the pitch angle of the body 1 can be rotated. Furthermore, the rubber ring 17 increases the friction between the male head 6 and the female head 7 to prevent the male head 6 from rotating accidentally, thereby ensuring the stability of the projector during use.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
