[0001] This utility model belongs to the field of lectern technology, specifically relating to a lectern with a telescopic camera device. Background Technology
[0002] When a class typically has a large number of students, and many students gather around a lectern to watch a teacher explain and demonstrate, not all students can see the demonstration process. This results in poor demonstration efficiency, an inability to fully showcase the experiment, and a less effective teaching outcome.
[0003] The existing method involves installing a camera on the lectern to film the experiments or courseware on it, and then connecting the camera to an external display screen to project the filmed content. This allows all students to watch the demonstration process, improving demonstration efficiency, fully showcasing the experimental demonstration, and enhancing teaching effectiveness.
[0004] However, the cameras on existing lecterns are usually fixed. When large objects need to be displayed over a large area, the camera needs to be raised to a certain height to meet the requirements. This means that the cameras on existing lecterns cannot be adjusted in horizontal and vertical positions according to actual needs, thus reducing the overall practicality of the lectern. Utility Model Content
[0005] The purpose of this utility model is to provide a lectern with a telescopic camera device, which solves the problem that the cameras on existing lecterns are usually fixed. When large objects need to be displayed over a large area, the camera needs to be raised to a certain height to meet the requirements. As a result, the camera on existing lecterns cannot be adjusted in horizontal and vertical position according to actual needs, thus reducing the overall practicality of the lectern.
[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: it includes a lectern and a camera, wherein the camera is located on one side of the lectern.
[0007] It also includes adjustment components,

[0022] This utility model provides a lectern with a telescopic camera device, including a lectern 101, a camera 102, and an adjustment assembly. The adjustment assembly includes a horizontal support 103, a horizontal slider 104, a connecting frame 105, a vertical support 106, a vertical slider 107, a screw 108, a mounting frame 109, a rotating component, a locking plate 110, and a second bolt 111. The rotating component includes a rotating seat 112, a rotating rod 113, a rotating head 114, a limiting ring 115, and a first bolt 116. This solution addresses the problem that existing lectern cameras are typically fixed. When displaying large objects over a large area, the camera needs to be raised to a certain height to meet the requirements, thus preventing the horizontal and vertical position adjustment of the camera and reducing the overall practicality of the lectern. This solution can be used when the position of the camera needs to be adjusted.
[0023] In this embodiment, the camera 102 is mounted on the lectern 101. By connecting the camera 102 to an external projection device, the teaching experiments and objects on the lectern 101 can be displayed, thereby helping teachers achieve their teaching objectives.
[0024] The horizontal support 103 is fixedly connected to the lectern 101 and located on one side of the lectern 101. The horizontal slider 104 is slidably connected to the horizontal support 103 and located on one side of the horizontal support 103. The connecting frame 105 is fixedly connected to the horizontal slider 104 and located on one side of the horizontal slider 104. The vertical support 106 is fixedly connected to the connecting frame 105 and located on one side of the connecting frame 105. The vertical slider 107 is slidably connected to the vertical support 106 and located on one side of the vertical support 106. The screw 108 is connected to the vertical support 106 through the rotating member and is threadedly connected to the vertical slider 107, and is located on the side of the horizontal support 101. The vertical support 106 is located near the vertical slider 107. The mounting bracket 109 is fixedly connected to the vertical slider 107 and connected to the camera 102, and is located on the side of the vertical slider 107 near the camera 102. The rotating component is mounted on the vertical support 106 and connected to the screw 108. The horizontal support 103 is welded to the lectern 101. The horizontal support 103 has a horizontal groove. The horizontal slider 104 is slidably connected to the horizontal groove of the horizontal support 103. The horizontal support 103 can connect, support, and limit the left and right movement of the horizontal slider 104. The connecting bracket 105 is welded to the horizontal slider 104. The horizontal slider 104 moves, causing the connecting frame 105 to move left and right. The vertical support 106 is welded to the connecting frame 105, and the left and right movement of the connecting frame 105 causes the vertical support 106 to move left and right. The vertical support 106 has a vertical groove, and the vertical slider 107 is slidably connected to the vertical groove of the vertical support 106. The vertical support 106 provides connection support and directional limitation for the sliding of the vertical slider 107. The screw 108 is connected to the vertical support 106 through the rotating member, which allows the teacher to easily rotate the screw 108. The screw 108 is threadedly connected to the connecting frame 105. On the vertical support 106, the screw 108's thread and the vertical support 106's directional limiting effect on the vertical slider 107 allow the screw 108 to rotate, thus driving the vertical slider 107 to move up and down within the vertical support 106. The mounting bracket 109 is welded to the vertical slider 107, and the camera 102 is mounted on the mounting bracket 109. The movement of the vertical slider 107 allows for the adjustment of the camera 102 on the mounting bracket 109. A rotating component is mounted on the vertical support 106 and connected to the screw 108, allowing the teacher to easily rotate the screw 108.This allows teachers to easily adjust the horizontal slider 104 within the horizontal support 103 to move left and right when they need to photograph and explain the courseware on the lectern 101. The left-right movement of the horizontal slider 104 drives the left-right movement of the vertical slider 107 within the vertical support 106 on the connecting frame 105. Simultaneously, the rotating component drives the screw 108 to rotate, and the screw thread and the vertical support 106 provide directional control for the movement of the vertical slider 107. When the screw 108 rotates, it drives the vertical slider 107 to move up and down within the vertical support 106. The movement of the vertical slider 107 allows the camera 102 on the mounting bracket 109 to move left and right or up and down for adjustment. Thus, by adjusting the left and right movement of the horizontal slider 104 and the up and down movement of the vertical slider 107, the camera 102 can be adjusted left and right or up and down, allowing the teacher to flexibly adjust the shooting angle of the camera 102 according to needs, thereby improving the overall practicality of the lectern 101.
[0025] Secondly, the rotating seat 112 is fixedly connected to the vertical support 106 and is located on one side of the vertical support 106; the rotating rod 113 is rotatably connected to the rotating seat 112 and fixedly connected to the screw 108, and is located on the side of the rotating seat 112 close to the screw 108; the rotating head 114 is fixedly connected to the rotating rod 113 and is located on the side of the rotating rod 113 away from the screw 108. The rotating seat 112 is welded to the vertical support 106, and the rotating rod 113 is rotatably connected inside the rotating seat 112. The rotating seat 112 can connect and support the rotation of the rotating rod 113. The screw 108 is welded below the rotating rod 113, and the rotating head 114 is welded above the rotating rod 113. The operator can rotate the rotating head 114 to drive the screw 108 on the rotating rod 113 to rotate.
[0026] Meanwhile, the limiting ring 115 is fixedly connected to the rotating rod 113 and is located on the side of the rotating rod 113 near the rotating seat 112. The limiting ring 115 is welded to the rotating rod 113 and is located inside the rotating seat 112. The limiting ring 115 can limit the rotation of the rotating rod 113 inside the rotating seat 112, thereby preventing the rotating rod 113 from coming out of the rotating seat 112 when it rotates inside the rotating seat 112.
[0027] In addition, the first bolt 116 is disposed on the rotating seat 112 and abuts against the limiting ring 115. The first bolt 116 is disposed on the rotating seat 112. By turning the first bolt 116, the first bolt 116 can abut against the outside of the limiting ring 115. Thus, the friction force when the first bolt 116 abuts can restrict the vertical movement of the vertical slider 107 within the vertical support 106 when necessary.
[0028] Finally, the locking plate 110 is fixedly connected to the connecting frame 105 and is located on one side of the connecting frame 105; the second bolt 111 is disposed on the locking plate 110 and abuts against the transverse support 103. The locking plate 110 is welded to the connecting frame 105. The second bolt 111 is disposed on the locking plate 110. By turning the second bolt 111, the second bolt 111 can abut against the outside of the transverse support 103. Then, the friction force when the second bolt 111 abuts can restrict the left and right movement of the transverse slider 104 on the connecting frame 105 within the transverse support 103 when necessary.
[0029] When using the lectern with a telescopic camera device according to this embodiment, if the teacher needs to film and explain the courseware on the lectern 101, the teacher can slide and adjust the horizontal slider 104 in the horizontal support 103 to move left and right as needed. The left and right movement of the horizontal slider 104 can drive the vertical slider 107 in the vertical support 106 on the connecting frame 105 to move left and right. At the same time, the rotating component can drive the screw 108 to rotate. The screw 108 thread and the vertical support 106 control the vertical slider 107. Under the directional limiting effect of the movement, when the screw 108 rotates, it can drive the vertical slider 107 to move up and down within the vertical bracket 106. The movement of the vertical slider 107 can drive the camera 102 on the mounting bracket 109 to move left and right or up and down for adjustment. Thus, by adjusting the left and right movement of the horizontal slider 104 and the up and down movement of the vertical slider 107, the camera 102 can be adjusted to move left and right or up and down, allowing the teacher to flexibly adjust the shooting angle of the camera 102 according to needs, thereby improving the overall practicality of the lectern 101.
