[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 , a recording and broadcasting equipment of a classroom, comprising a recording and broadcasting camera 1, the recording and broadcasting camera 1 is prior art, can record video and sound, the bottom of the recording and broadcasting camera 1 is provided with a fixing mechanism, and is fixed on a desk in the middle desk area of the middle of the classroom through the fixing mechanism, the fixing mechanism comprises a transverse fixing frame 2, support plates 3 are fixedly connected to the two sides of the inner wall of the transverse fixing frame 2, the support plates 3 abut against the top of the desk, two fixed clamping plates 4 are slidably connected to the support plates 3, and the two fixed clamping plates 4 are clamped on the front and rear sides of the desk respectively;

[0028] As Figure 1 and Figure 2 , one side of the inner wall of the transverse fixing frame 2 is rotatably connected with a first screw rod 5, one end of the first screw rod 5 is fixedly connected with a second screw rod 6, one end of the second screw rod 6 penetrates through the transverse fixing frame 2 and extends to the outside of the transverse fixing frame 2, one end of the second screw rod 6 located outside the transverse fixing frame 2 is fixedly connected with a rotating shaft 7, the rotating shaft 7 is manually rotated, and the first screw rod 5 and the second screw rod 6 are driven to rotate;

[0029] The first screw rod 5 and the second screw rod 6 are oppositely threaded, and the two fixed clamping plates 4 are respectively threaded on the first screw rod 5 and the second screw rod 6, so that when the first screw rod 5 and the second screw rod 6 rotate in the same direction, the two fixed clamping plates 4 can be driven to move close to or away from each other, and the supporting plate 3 passes through the fixed clamping plate 4, so that the fixed clamping plate 4 can only move horizontally.

[0030] As Figure 2 And Figure 3 The two sides of the transverse fixing frame 2 are respectively provided with auxiliary frames 8, the bottom of the auxiliary frame 8 and the bottom of the supporting plate 3 are located on the same plane, and when the bottom of the supporting plate 3 is abutted on the desktop, the bottom of the auxiliary frame 8 can also be abutted on the desktop.

[0031] As Figure 1 And Figure 2 A positioning slot is formed at the center of the top of the transverse fixing frame 2, and a positioning lug 9 is fixedly connected at the center of the bottom of the recording and broadcasting camera 1, the positioning lug 9 is located in the positioning slot, and the positioning between the transverse fixing frame 2 and the recording and broadcasting camera 1 can be realized.

[0032] As Figure 1 And Figure 2 The bottom of the transverse fixing frame 2 is provided with a first fixing bolt 10, the first fixing bolt 10 passes through the transverse fixing frame 2 and is threaded with the recording and broadcasting camera 1, so that the transverse fixing frame 2 and the recording and broadcasting camera 1 can be fixed, and the bottom of the auxiliary frame 8 is provided with a second fixing bolt 11, the second fixing bolt 11 passes through the auxiliary frame 8 and is threaded with the recording and broadcasting camera 1, so that the auxiliary frame 8 and the recording and broadcasting camera 1 can be fixed.

[0033] The working principle of the recording and broadcasting equipment for a classroom provided by the embodiment one of the utility model is as follows:

[0034] Firstly, the recording and broadcasting camera 1 is placed on a desk in the middle of the classroom, so that the supporting plate 3 is abutted on the top of the desk, the rotating shaft 7 is manually rotated in different directions, so that the first screw rod 5 and the second screw rod 6 are synchronously rotated, and the first screw rod 5 and the second screw rod 6 are rotated, so that the two fixed clamping plates 4 move close to or away from each other.

[0035] When the two fixed clamping plates 4 move close to each other, the two fixed clamping plates 4 can be clamped on the front and back sides of the desk, the transverse fixing frame 2 and the recording and broadcasting camera 1 are fixed, the recording and broadcasting camera 1 is fixed on the desk in the middle of the classroom, and when the two fixed clamping plates 4 move away from each other, the recording and broadcasting camera 1 can be taken off the desk.

[0036] Compared with the related art, the recording and broadcasting equipment for a classroom provided by the embodiment one of the utility model has the following beneficial effects:

[0037] This invention, by setting a fixing mechanism at the bottom of the recording camera 1, allows the support plate 3 to be placed against the top of the desk. As the first fixing bolt 10 and the second fixing bolt 11 rotate, the two fixing plates 4 move closer to each other and clamp onto the front and back sides of the desk, thereby fixing the recording camera 1 on the desk in the middle of the central desk area. This allows the recording camera 1 to be used for recording in the classroom, directly facing the podium in the center of the classroom, fully covering the teacher's lecture, blackboard writing, and student interaction scenes, reducing blind spots in the image. At the same time, the central position makes the lens more symmetrical and avoids image distortion or obstruction caused by angle shift.

[0038] Example 2

[0039] like Figure 5 and Figure 6 In Embodiment 2, the first fixing bolt 10 and the second fixing bolt 11 are no longer used to fix the recording camera 1;

[0040] Fixed clamping blocks 12 and movable clamping blocks 13 are respectively provided on both sides of the recording camera 1 and on the top of the horizontal fixing frame 2. The fixed clamping blocks 12 are fixed to the top of the horizontal fixing frame 2.

[0041] The top of the transverse fixing frame 2 is fixedly connected to a protruding plate 14, and an adjusting screw 15 is threadedly connected to the protruding plate 14. One end of the adjusting screw 15 is rotatably connected to the movable clamping block 13.

[0042] When the adjusting screw 15 is rotated, the movable clamping block 13 can be moved. When the movable clamping block 13 is close to the recording camera 1, it can cooperate with the protruding plate 14 to clamp and fix the recording camera 1. Conversely, when the movable clamping block 13 is far away from the recording camera 1, the recording camera 1 and the horizontal fixing frame 2 can be separated.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
