[0036] With the continuous development and progress of projection technology, projectors are widely used in daily life and office scenarios. There are many sizes of projectors. Small-sized projectors are convenient for daily carrying and can be used in multiple scenarios. Large-sized projectors have more functions and are more intelligent to use. Generally, projectors can be adjusted in angle through a pan-tilt head and can also be supported by a support frame, so as to perform projection work in different scenarios.

[0037] There are technical problems of complex connection and long time consumption when the projection device in the related art is connected to the support frame and the pan-tilt head.

[0038] Please refer to Figures 1-5, this embodiment provides a projection device, which includes a projection host and a bracket structure 100. The projection host and the bracket structure 100 are detachably connected and can be supported by the projection bracket. This projection device can effectively improve the above-mentioned technical problems, enable the quick connection and disconnection of the pan-tilt 20 and the support frame, and is more convenient to use.

[0039] Please refer to Figures 1-5 , the bracket structure 100 includes a support rod 10, a pan-tilt 20, a locking knob 30, and a clamping member 40. The pan-tilt 20 is located at the top of the support rod 10. The locking knob 30 is sleeved on the top of the support rod 10, and the locking knob 30 is connected to the pan-tilt 20. The clamping member 40 is arranged on the pan-tilt 20 and fixedly connected to the pan-tilt 20. The locking knob 30 is used to squeeze the clamping member 40 towards the support rod 10 when connected to the pan-tilt 20.

[0040] Specifically, there are various types of projectors in the prior art. Some projectors can come with their own brackets to adjust the rotation angle and pitch angle of the projector, etc. During the use of the projector, the pan-tilt 20 is needed to achieve stable projection work. The pan-tilt 20 is generally installed under the projector. When an external bracket is needed for support, the pan-tilt 20 and the bracket are connected. Generally, the connection between the projector with the pan-tilt 20 installed and the bracket is relatively complex, and the pan-tilt 20 is prone to rotation after connection, thus affecting the normal operation of the projector. To solve this technical problem, when the bracket structure 100 provided in this embodiment is in use, the pan-tilt 20 is arranged at the top of the support rod 10, the clamping member 40 is arranged on the pan-tilt 20 and fixedly connected to the pan-tilt 20. The pan-tilt 20 is connected to the locking knob 30 to achieve the quick connection between the pan-tilt 20 and the support rod 10. At the same time of connection, the locking knob 30 can squeeze the clamping member 40 towards the support rod 10, so that the clamping member 40 clamps the support rod 10, and the pan-tilt 20 is stably installed at the top of the support rod 10. This bracket structure 100 can achieve quick connection, shorten the installation time, and is more convenient to use.

[0041] Please refer to Figure 2 , the clamping member 40 includes a cover plate 41 and a plurality of clamping teeth 42. The plurality of clamping teeth 42 are arranged at intervals along the circumferential direction, and the plurality of clamping teeth 42 are all connected to the edge of the cover plate 41.

[0045] Furthermore, the pan-tilt 20 further includes an elastic pad 23. The elastic pad 23 is arranged on the mounting plate 21, and the elastic pad 23 can achieve a shock-absorbing effect after the projection host is connected to the mounting plate 21. Specifically, the elastic pad 23 is a silica gel pad.

[0046] Specifically, the clamping tooth 42 has a first inclined surface 421. When the connecting portion 22 and the locking knob 30 are threadedly connected, the clamping tooth 42 is inserted between the locking knob 30 and the support rod 10, and the locking knob 30 presses the first inclined surface 421 inward. Among them, the first inclined surface 421 is arranged on the outer surface of the clamping tooth 42. During the threaded connection process of the locking knob 30 and the connecting portion 22, the clamping tooth 42 is inserted between the locking knob 30 and the support rod 10 through the first inclined surface 421, and clamps the support rod 10 under the action of the pressing force of the locking knob 30.

[0047] In this embodiment, the slope range of the first inclined surface 421 is 9°-11°. Specifically, the slope of the first inclined surface 421 is 10°. In other embodiments, the slope of the first inclined surface 421 can also be 9°, 9.8°, 10.2° or 11°, and no specific limitation is made here.

[0048] Furthermore, the locking knob 30 has a second inclined surface 31, and the second inclined surface 31 is used to cooperate with the first inclined surface 421 when the clamping tooth 42 is inserted between the locking knob 30 and the support rod 10.
