Description

Multi-screen display for video processing

Technical Field

The present invention relates to the field of displays, and in particular to a multi-screen display for video processing.

Background technique

When creating videos, video authors often need to crop and edit different video materials, or perform different processing on different video clips. When processing videos, they often need to constantly switch between different work interfaces. At this time, multi-screen displays are needed to help display multiple editing interfaces to avoid the tediousness of constant switching. Existing multi-screen displays are usually fixed structures, and the distance, position and angle between the screens cannot be adjusted, so the author needs to adjust his operating habits according to the distribution of the screens.

A Chinese utility model patent with announcement number CN209622367U discloses a multi-screen display, which uses multiple six-dimensional angle adjustment mechanisms to adjust the display screens connected thereto, thereby achieving the function of freely adjusting the display angle.

However, the utility model can only adjust the angle of the display, and cannot adjust the position and distance between the screens.

Based on this, the present invention provides a multi-screen display for video processing.

Detailed ways

The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 27, a multi-screen display for video processing includes a supporting mechanism 3, which includes a base 301. A threaded rod 302 is rotatably installed in the base 301, and a bevel gear is fixedly installed at the bottom of the threaded rod 302. An adjusting button 303 is rotatably installed on the base 301, and a bevel gear is fixedly installed on the adjusting button 303. The bevel gear on the adjusting button 303 meshes with the bevel gear at the bottom of the threaded rod 302. A main screen group 2 is slidably installed on the supporting mechanism 3. The main screen group 2 includes a main screen 201, and a main screen slider 202 is fixedly installed on the main screen 201. The main screen slider 202 is slidably installed in the base 301. The main screen 201 cooperates with the threaded rod 302. The adjusting button 303 is turned to drive the threaded rod 302 to rotate in the base 301, and the main screen 201 is driven to slide on the base 301 to adjust its height.

As shown in Figures 1 to 27, a sub-screen slide groove 203 is fixedly installed on the main screen 201, and a sub-screen group 1 is movably installed on the main screen group 2. The sub-screen group 1 includes a third adjusting block 119, and the third adjusting block 119 is slidably installed in the sub-screen slide groove 203. The first support rod 106 is rotatably installed on the third adjusting block 119 in the upper half of the sub-screen slide groove 203, and the second support rod 108 is rotatably installed on the third adjusting block 119 in the lower half of the sub-screen slide groove 203. The first adjusting gear 123 and the second adjusting gear 124 are rotatably installed in the third adjusting block 119, and the first adjusting gear 123 and the second adjusting gear 124 are meshed with the inner side of the sub-screen slide groove 203. The gear pattern is meshed with the gear pattern of the second adjusting gear 124, and a small gear is fixedly installed on the second adjusting gear 124. A positioning adjustment rod 122 is rotatably installed in the third adjusting block 119. A gear is fixedly installed at the bottom of the positioning adjustment rod 122. The gear at the bottom of the positioning adjustment rod 122 meshes with the small gear on the second adjusting gear 124. A hollow gear is fixedly installed on the third adjusting block 119, and a gear pattern is provided on the upper half of the inner ring of the hollow gear. A hollow adjusting rod 121 is slidably installed on the positioning adjustment rod 122. The positioning adjustment rod 122 is driven to rotate by rotating the hollow adjusting rod 121. The second adjusting gear 124 and the first adjusting gear 123 are driven to rotate by rotating the positioning adjustment rod 122, thereby driving the third adjusting block 119 to slide in the auxiliary screen slide groove 203 to adjust the height position. A compression spring is installed between the hollow adjusting rod 121 and the positioning adjusting rod 122, and a gear is provided at the bottom of the hollow adjusting rod 121. The gear at the bottom of the hollow adjusting rod 121 slides with the gear pattern on the third adjusting block 119. The rotational movement of the hollow adjusting rod 121 can be limited by the gear at the bottom of the hollow adjusting rod 121 and the gear pattern on the third adjusting block 119, so that the positioning adjusting rod 122 can no longer rotate, and the second adjusting gear 124 is controlled not to rotate, so that the third adjusting block 119 can be fixed in the current position. A pair of adjusting arc plates 120 are slidably installed in the second support rod 108 and the first support rod 106, and a compression spring is fixedly installed between the outer side of the adjusting arc plate 120 and the second support rod 108 and the first support rod 106. A gear pattern is provided on the inner side of the adjusting arc plate 120, and the gear pattern on the adjusting arc plate 120 cooperates with the hollow gear on the third adjusting block 119. The gear pattern on the adjusting arc plate 120 is made to fit on the hollow gear on the third adjusting block 119 by adjusting the compression spring between the arc plate 120 and the second support rod 108 and the first support rod 106, so as to limit the rotation angle of the second support rod 108 and the first support rod 106 on the third adjusting block 119. When rotation is required, the adjusting arc plates 120 on both sides are pressed inward to separate the gear pattern on the adjusting arc plate 120 from the hollow gear on the third adjusting block 119. After adjusting the angle, release the pressure on the adjusting arc plate 120 so that it returns to its original position through the spring, thereby locking the adjusted angle.

A second connecting rod 117 is hinged between the cylindrical key on the telescopic rod 105 and the cylindrical key on the positioning rack block 116. The combination can control the sliding position of the positioning rack block 116 in the first connecting rod 113, and control the angle between the telescopic rod 105 and the first connecting rod 113 by hinged connection of the second connecting rod 117 and the telescopic rod 105. When the second positioning rod 115 is pressed, the rack on the second positioning rod 115 no longer cooperates with the positioning rack block 116. At this time, the angle between the telescopic rod 105 and the first connecting rod 113 can be changed. At the same time, the positioning rack block 116 is driven to slide in the first connecting rod 113 by the second connecting rod 117. The pressure on the second positioning rod 115 is released, so that it returns to its original position through the spring, and the rack on the second positioning rod 115 cooperates with the positioning rack block 116 to fix the position of the positioning rack block 116 in the first connecting rod 113, thereby fixing the angle between the telescopic rod 105 and the first connecting rod 113.
