Description

Technical Field

[0001] The utility model belongs to the technical field of film and television shooting, and particularly relates to a guide rail mechanism used for film and television shooting. Background Art

[0002] According to the disclosed patent with publication number CN114110379B, a guide rail mechanism for filming can be quickly moved when in use, and has a quick disassembly and assembly structure, which improves the working efficiency of filming, through the cooperation of the guide rail body, moving box, first motor, ball screw, ball nut, moving plate, universal wheel, second motor, threaded rod, threaded tube, limit card plate, limit hole, buffer box, buffer slide bar, first spring, buffer slider, buffer rod, installation box, double-axis motor, worm, worm gear, fastening bolt, installation plate, limit slide bar, positioning plate, second spring, installation rod, installation block, support plate and slide cylinder.

[0003] The moving distance of the guide rail mechanism is fixed. When the shooting distance needs to be extended, the guide rail needs to be moved as a whole or other shooting methods need to be used, which results in insufficient moving distance during the shooting process, resulting in poor shooting effects. Therefore, we propose a guide rail mechanism for film and television shooting. Utility Model Content

[0004] The purpose of the utility model is to provide a guide rail mechanism for filming of films and televisions, which can extend the distance by setting an extension component, avoid insufficient movement distance during shooting, improve the shooting effect, and do not require staff to adjust the position of the device again, thereby solving the problem that the moving distance of the guide rail mechanism is fixed, and when the shooting distance needs to be extended, the guide rail needs to be moved as a whole or other shooting methods need to be used, resulting in poor shooting effect.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a guide rail mechanism for filming, comprising a fixed seat, a slide bar is fixedly connected to the top of the fixed seat, an extension component is arranged above the slide bar, the extension component comprises an extension plate, and a driving seat and a slide block are fixedly connected to the bottom of the extension plate;

[0007] A support block 1 is fixedly connected to the left side of the driving seat, a motor 1 is fixedly connected to the front of the support block 1, a belt pulley 1 is fixedly connected to the output end of the back side of the motor 1, a rotating shaft is rotatably connected inside the driving seat, and a driving wheel 1 and a belt pulley 2 are respectively fixedly connected to the outer surface of the rotating shaft. By setting an extension component, the distance can be extended to avoid insufficient moving distance during shooting, thereby improving the shooting effect and eliminating the need for staff to adjust the position of the device again.

[0008] Furthermore, the top of the extension plate is fixedly connected with a fixing frame and a guide rail respectively, a camera placement platform is arranged above the extension plate, the front and back sides of the rotating shaft are rotatably connected with support blocks 2, the bottom of the support block 2 is fixedly connected to the outer surface of the driving seat, and the support block 2 is used to support the rotating shaft, thereby improving the stability of the driving wheel 1 when it moves. The movement of the driving wheel 2 is facilitated by setting a fixing frame.

[0009] Furthermore, a fixing block is fixedly connected to the outer surface of the fixing seat, a threaded rod is fixedly connected to the bottom of the fixing block, a limiting block is fixedly connected to the bottom of the threaded rod, a supporting column is arranged on the outer side of the limiting block, a threaded ring is arranged on the top of the supporting column, and the bottom of the threaded ring is rotatably connected to the limiting ring. By setting the supporting column, specifically by rotating the threaded ring, the threaded rod will drive the fixing block to move upward or downward, thereby adjusting the level of the fixing seat. Since the threaded ring is limited by the limiting ring, the threaded ring can only rotate in place. Since the four corners of the fixing seat can be fine-tuned individually, the fixing seat can be placed more stably, reducing the tilting situation and improving the stability during shooting.

[0010] Furthermore, a support block three and a slide seat are fixedly connected to the bottom of the camera placement platform, a motor two is fixedly connected to the back of the support block three, and a driving wheel two is fixedly connected to the front output end of the motor two. When the motor two is started to drive the driving wheel two to rotate, the driving wheel two moves on the fixed frame, thereby driving the camera placement platform to move, so that the position can be automatically moved during shooting.

[0011] Furthermore, the driving seat is slidably connected to the fixed seat, the belt pulley 1 is transmission-connected to the belt pulley 2 through a belt, the outer surface of the driving wheel 1 is in contact with the bottom of the fixed seat, and the slider is slidably connected to the slide rod. The slider and the slide rod cooperate to support the extension plate and improve the stability of the extension plate during movement.

[0012] Furthermore, the slide is slidably connected to the guide rail, the second outer surface of the driving wheel contacts the outer surface of the fixed frame, the bottom of the threaded rod passes through the threaded ring and extends to the inside of the support column, and the slide can limit the camera placement platform, allowing the camera placement platform to move in a straight line, thereby improving the shooting effect.

[0013] Furthermore, the threaded rod is threadedly connected to the threaded ring, the limit block is slidably connected to the support column, the bottom of the limit ring is fixedly connected to the top of the support column, and the limit ring is used to limit the threaded ring, so that the threaded rod can drive the fixed seat to rise and fall through the fixed block.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets an extension component, specifically, starts motor 1 to drive belt pulley 1 to rotate, then belt pulley 1 drives driving wheel 1 to rotate through belt pulley 2 and a rotating shaft, then driving wheel 1 moves at the bottom of the fixed seat, thereby driving the extension plate to move left or right through the driving seat, which can play a role in extending the distance, avoid insufficient moving distance during shooting, improve the shooting effect, and do not need the staff to adjust the position of the device again.

[0016] 2. The utility model sets a support column. Specifically, by rotating the threaded ring, the threaded rod will drive the fixed block to move upward or downward, thereby adjusting the level of the fixed seat. Since the threaded ring is limited by the limit ring, the threaded ring can only rotate in place. Since the four corners of the fixed seat can be fine-tuned individually, the fixed seat can be placed more stably, reduce tilting, and improve stability during shooting.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Since the threaded ring 141 is limited by the limiting ring 142, the threaded ring 141 can only rotate in place. Since the four corners of the fixing base 1 can be fine-tuned individually, the fixing base 1 can be placed more firmly, reduce the tilting situation, and improve the stability during shooting. Then install the camera on the camera placement platform 13. During the shooting process, start the motor 2 132 to drive the driving wheel 2 133 to rotate, so that the driving wheel 2 133 moves on the fixing frame 211, thereby driving When the camera placement table 13 moves, the slide 134 slides on the guide rail 212, so that the position can be automatically moved during shooting.
