Description

Technical Field

[0001] The present application relates to the field of video acquisition technology, and in particular to an experimental operation video acquisition device equipped with an independent lifting multimedia socket. Background Art

[0002] The current laboratory video examination equipment for junior and senior high schools mainly uses two shooting perspectives, one is a top-down perspective, and the other is a combination of a top-down perspective and a single side perspective. However, as the experimental content becomes richer, the desktop scenes are gradually becoming more diversified.

[0003] Existing video capture products are unable to achieve comprehensive recording of test monitoring from four perspectives: front, top, left, and right. This results in insufficient comprehensiveness of video recording and prone to blind spots, which in turn causes the captured video to be incomplete, affecting subsequent playback viewing.

[0006] As a preferred embodiment, a bearing is fixedly mounted on the inner bottom of the square groove, and the bottom end of the screw rod is fixedly connected to the inner wall of the bearing.

[0007] By adopting the above technical solution, it is possible to position the screw rod during rotation, thereby ensuring that the screw rod will not be randomly offset in position during rotation.

[0008] As a preferred embodiment, a threaded hole is opened on the inner wall of the slider, the screw rod is threadedly connected to the inner wall of the threaded hole, the slider is slidably connected to the inner wall of the square groove, and the limit plate is slidably connected to the outer side of the device body.

[0009] By adopting the above technical solution, the position of the slider can be adjusted by using the threaded hole when the screw rod rotates, and then the position of the side rocker arm can be adjusted, thereby adjusting the position of the connecting arm. The slider can be limited by the limit plate to ensure that the slider will not rotate along with the force of the screw rod when the screw rod rotates.

[0010] As a preferred implementation, a side of the extension wall close to the side rocker arm is slidably connected to an inner wall of the side rocker arm, and a size of the extension wall close to the side rocker arm is matched with a size of the inner wall of the side rocker arm.

[0011] By adopting the above technical solution, the extension wall can slide on the inner wall of the side rocker arm, thereby adjusting the extension length of the connecting arm.

[0012] As a preferred embodiment, the number of the side rocker arms, electric telescopic rods, extension walls and connecting arms is two, and the two side rocker arms, electric telescopic rods, extension walls and connecting arms are symmetrically arranged on the outer sides of the limit plate, and cameras are fixedly installed at the bottom of the two connecting arms.

[0013] By adopting the above technical solution, the desktop can be recorded at a symmetrical angle to ensure the integrity of the recording.

[0014] As a preferred embodiment, a camera is also fixedly mounted on the primary bottom of the top rocker arm away from the connecting rod.

[0015] By adopting the above technical solution, the entire desktop can be photographed from a bird's-eye view.
