[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment: a video recording device for ideological and political remote teaching, including a base 1, a slide 2 is fixedly connected to the top of the base 1, a lead screw 3 is rotatably connected to the middle of the slide 2, one end of the lead screw 3 passes through the slide 2 and is fixedly connected to a handle 6, and the lead screw 3 can be rotated more conveniently by rotating the handle 6. The outer periphery of the lead screw 3 is threadedly connected to a slider 4, and a video recorder 5 is installed on the top of the slider 4. The slider 4 can be driven to move by rotating the lead screw 3 to adjust the position of the video recorder 5, and then a connecting frame is installed between the slider 4 and the video recorder 5. The connecting frame can rotate in the horizontal and vertical directions, which is a prior art and will not be described excessively here, so as to adjust the angle of the video recorder 5. A threaded rod 7 is threadedly connected to the middle part of the base 1, and a clamping plate 8 is rotatably connected to the bottom of the threaded rod 7. When installing the device, the bent part of the base 1 is inserted into the desktop of the ideological and political classroom, and then the threaded rod 7 is rotated to move the clamping plate 8 downward. In cooperation with the lower part of the base 1, the device is clamped on the desktop, thereby achieving the installation and fixation of the equipment to avoid shaking and tipping caused by placing the video recorder 5 on the desktop when working.

[0032] Reference Figure 2-Figure 3The bottom of the clamping plate 8 and the bottom of the base 1 are fixedly connected with anti-skid pads 9, and the end of the threaded rod 7 away from the clamping plate 8 is fixedly connected with a knob 11. The anti-skid pad 9 can protect the desktop of the desk to ensure clamping while avoiding damage to the desktop. The threaded rod 7 can be rotated more conveniently through the knob 11 to better complete the installation of the device. The bottom of the base 1 is fixedly connected with an extension plate 10, and the folded edge of the base 1 can be extended through the extension plate 10 to better fix the base 1 and the desk desktop. The top of the base 1 is fixedly connected with a frame 14, and the outside of the frame 14 is covered with a dustproof cloth 21. The frame 14 can protect the entire device and reduce external collisions. At the same time, the frame 14 can also provide support for the dustproof cloth 21 to prevent the dustproof cloth 21 from directly covering the upper part of the video recorder 5. When the device is not applicable, the dustproof cloth 21 is put down to cover the device for dustproof treatment. A locking bolt 12 is threadedly connected to the middle of the front side of the base 1, and a pad 13 is rotatably connected to the bottom of the locking bolt 12. When the base 1 and the desktop are connected, the locking bolt 12 can be rotated to make the pad 13 fit better with the desktop, thereby improving the clamping and fixing effect.

[0033] Reference Figure 3-Figure 4 The top of the frame 14 is fixedly connected with a clamping assembly, and the dustproof cloth 21 is located in the middle of the clamping assembly. The dustproof cloth 21 can be clamped by the clamping assembly to prevent the dustproof cloth 21 from falling downward when the video recorder 5 is working. The clamping assembly includes a mounting structure and a mounting plate 16. The mounting structure is located above the frame 14. The mounting plate 16 is fixedly connected to the upper part of the mounting structure. The mounting plate 16 is mounted on the upper part of the frame 14 through the mounting structure. A telescopic rod 20 is fixedly connected to the upper part of the mounting plate 16, and a pull ring is rotatably connected to the top of the telescopic rod 20. The telescopic rod 20 can be pulled better by using the pull ring. A pressure rod 18 is rotatably connected to the top of the mounting plate 16 through a torsion spring 17. A bending portion is provided in the middle of the pressure rod 18. The dustproof cloth 21 is located in the middle of the bending portion after being retracted. After the bending portion is provided in the middle of the pressure rod 18, the dustproof cloth 21 can be better placed after the dustproof cloth 21 is rolled up. The top of the pressure rod 18 is rotatably connected to a connecting rod 19 , and the other end of the connecting rod 19 is rotatably connected to the outside of the telescopic rod 20 .

[0034] Reference Figure 3-Figure 4, because the course content of ideological and political distance education is time-sensitive and limited, after recording a batch, the frequency of use of the video equipment will decrease. At this time, the video equipment needs to be stored. At this time, the dustproof cloth 21 can be pulled down from the top of the frame 14 to protect the entire video equipment from dust. If it needs to be used again, the telescopic rod 20 can be pulled upward, and then the dustproof cloth 21 can be rolled up and placed on the bend in the middle of the pressure rod 18. After loosening the telescopic rod 20, the pressure rod 18 can be rotated under the action of the torsion spring 17. After the pressure rod 18 cooperates with the top of the frame 14, the dustproof cloth 21 can be clamped, so as to avoid the problem of the dustproof cloth 21 scattering and affecting the operation of the video recorder 5. The mounting structure includes a mounting member 15, which is fixedly connected to the top of the frame 14, and the mounting member 15 is divided into an upper and lower part, and the dustproof cloth 21 is clamped between the two parts of the mounting member 15. During installation, the center of the dustproof cloth 21 is first placed above the frame 14, and then one part of the mounting member 15 is placed on the top of the frame 14, and then the other part of the mounting member 15 is placed above the dustproof cloth 21. After aligning the two parts of the mounting member 15, they are installed by bolts, so that the dustproof cloth 21 can be fixed and the clamping component can be installed at the same time. A handle 22 is fixedly connected to the top of the frame 14, and the handle 22 can be used to more conveniently carry the video recording device.

[0035] Working principle: When in use, the device is carried to the ideological and political classroom, and then the side port of the base 1 is plugged into the edge of the classroom desk, and then the threaded rod 7 is rotated by turning the knob 11, thereby driving the clamping plate 8 to move downward, and when cooperating with the lower edge of the base 1, the base 1 and the desk surface are clamped and fixed, thus completing the fixation of the device. During this period, the locking bolt 12 can also be rotated to adjust the position of the pad 13, so as to further strengthen the connection strength between the device and the desk surface.

[0036] Secondly, after the device is installed, the screw 3 can be rotated by turning the handle 6, and the slider 4 can drive the video recorder 5 to move above the base 1, so as to fine-tune the position of the video recorder 5. At the same time, the connecting frame between the video recorder 5 and the slider 4 can be rotated and adjusted forward and backward, and the direction of the video recorder 5 can be changed, so that the video recorder 5 can be better aligned with the classroom blackboard, so as to better record. The connecting frame is a prior art and is mainly used to adjust the left and right rotation angles and the up and down rotation angles of the video recorder 5, which will not be excessively described here.

[0037] Finally, if the device is not in use, the dustproof cloth 21 can be put down, and the structures such as the video recorder 5 can be protected along the frame 14, so that the video recorder 5 can be dust-proofed. At the same time, when in use, the dustproof cloth 21 can be retracted and the telescopic rod 20 can be pulled upward. At this time, the telescopic rod 20 will be retracted and the connecting rod 19 will be driven to rotate, thereby driving the pressure rod 18 to rotate synchronously. Then, the rolled dustproof cloth 21 is placed on the bend in the middle of the pressure rod 18, and the dustproof cloth 21 can be placed. After loosening the telescopic rod 20, the pressure rod 18 can be reset under the action of the torsion spring 17, so that the dustproof cloth 21 can be clamped, and the video recorder 5 can be used normally.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
