Description

Technical Field

[0001] The utility model relates to the technical field of stereoscopic imaging devices, and more specifically, to a placement platform for a stereoscopic imaging device. Background Art

[0002] Stereoscopic imaging can be divided into two categories: static scene shooting and dynamic scene shooting. For static scene shooting, you only need to use one camera to take a photo at a certain position and angle, and then move the camera parallelly for a distance and take another photo. In this way, you will get a set of stereoscopic photos with parallax. For dynamic scene shooting, you need to use a special stereo camera, or use two cameras to take two photos at the same time to achieve the same effect.

[0003] When using the stereoscopic imaging device, operators often use a corresponding placement platform to place and fix the stereoscopic imaging device. In actual use, although the existing placement platform has basic placement and fixing functions, the general placement platform mostly adopts a fixed connection method for the projection screen. In this way, when the projection screen is damaged or the platform needs to be transported, its replacement and disassembly operation is very inconvenient, which not only reduces the efficiency of the disassembly and assembly of the projection screen, but also increases the labor intensity of the operator. Therefore, it needs to be improved. Utility Model Content

[0030] Among them, the fixing mechanism includes a driving motor 6, which is fixedly installed on the left side of the mounting plate 5. The other end of the output shaft of the driving motor 6 is fixedly sleeved with a threaded rod 7. The other end of the threaded rod 7 penetrates the mounting plate 5 and extends between the mounting plates 5 and is movably sleeved with the left side of the mounting plate 5. A movable block 8 is threadedly sleeved on the outer surface of the threaded rod 7. A limit block 9 is fixedly installed on the top of the movable block 8. The outer surface of the limit block 9 is movably connected to the inside of the transverse groove 4. Both sides of the movable block 8 are hinged with inclined rods 10. The other end of the inclined rod 10 is hinged with a clamping plate 11. There are two clamping plates 11. The inner sides of the two clamping plates 11 are movably connected to the outer surface of the fixed seat 3. The forward and backward movement of the movable block 8 will cause the two clamping plates 11 to move toward or away from each other.

[0031] When the driving motor 6 starts to run, the threaded rod 7 rotates, and the movable block 8 drives the limit block 9 to move horizontally forward under the limiting action of the transverse groove 4, so that the two inclined rods 10 start to move, and finally the two clamping plates 11 move toward each other, thereby achieving the fixing effect on the fixed seat 3.

[0044] The working principle and use process of this utility model:

[0045] Firstly, when the placement platform needs to be transported, the mounting frame 1 can be pushed so that the roller 16 drives the rotating rod 15 to rotate. When it moves to the specified position, the power motor 17 is started so that the rotating shaft 18 drives the rotating plate 19 to rotate, and the two connecting rods 20 drive the two fixed plates 21 to move horizontally towards each other under the limiting action of the rotating rod 15, thereby achieving the fixing effect of the fixing sleeve 22, realizing the fixing function of the entire device, achieving the purpose of facilitating transportation, and reducing the labor intensity of the operator.

[0046] When the projection screen 2 is damaged during use and needs to be replaced, the drive motor 6 is started to rotate the threaded rod 7, and the movable block 8 drives the limit block 9 to move horizontally backward under the limiting action of the transverse groove 4, so that the two inclined rods 10 drive the two clamping plates 11 and the mounting block 13 to move horizontally backward under the limiting action of the limit groove 12, thereby releasing the fixing effect of the fixing seat 3, achieving the purpose of facilitating the disassembly and assembly of the projection screen 2, and reducing the labor intensity of the operator.
