Description

Technical Field

[0001] This utility model relates to the field of sliding bracket technology, and in particular to a track-type sliding bracket for studio lighting equipment.

[0002] Background technology.

[0003] In studio production scenarios, such as TV program recording, live broadcasts, and film and television clip shooting, the position, height, and illumination angle of lighting equipment need to be flexibly adjusted according to shooting requirements (such as close-up interviews, panoramic stages, and dynamic tracking shots) to ensure the uniformity of brightness, color reproduction, and visual depth of the image. Therefore, the track-type sliding bracket, as the core load-bearing and adjustment component of the lighting equipment, is crucial to the studio's production efficiency and content quality.

[0004] Existing studio lighting track supports have many shortcomings and are difficult to adapt to diverse production needs. Most supports rely on manual adjustment of height or lateral position. Especially when the supports are installed in high-altitude areas of the studio, operators need to use climbing equipment to work, which is not only cumbersome and inefficient, but also poses a safety hazard of falling from height. A few supports with automated adjustment functions only support single-dimensional adjustment, such as only vertical or only horizontal adjustment, and cannot realize the rotation adjustment of the light angle, which is difficult to meet the precise positioning requirements in complex lighting scenarios. Therefore, there is an urgent need for a track-type sliding support for studio lighting equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a track-type sliding bracket for studio lighting equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A track-type sliding bracket for studio lighting equipment includes: a heavy-duty track with a mounting plate on its bottom surface; and an adjustment assembly for adjusting the vertical movement of the lighting equipment. The adjustment assembly is disposed on the bottom surface of the heavy-duty track and includes: a main support tube disposed on the bottom surface of the heavy-duty track; a first slide table movably sleeved inside the main support tube; a first threaded hole on the top surface of the first slide table; a first threaded rod threadedly connected to the inner wall of the first threaded hole; a first drive motor fixedly mounted on the bottom surface of the main support tube; and the top surface of the drive shaft of the first drive motor fixedly mounted to the first threaded rod. A second support tube is fixedly installed on one side, and a second slide is movably sleeved inside the second support tube. A second threaded hole is opened on the top surface of the second slide, and a second threaded rod is threadedly connected to the inner circular wall of the second threaded hole. A third support tube is fixedly installed on one side of the second slide, and the third support tube is movably sleeved with the mounting slide plate. A third threaded hole is opened on the top surface of the mounting slide plate, and a third threaded rod is threadedly connected to the inner circular wall of the third threaded hole. A second drive motor and a third drive motor are fixedly installed on the top surfaces of the third support tube and the second support tube, respectively. The drive shafts of the second drive motor and the third drive motor are fixedly installed to the third threaded rod and the second threaded rod, respectively.

[0007] As a further embodiment of this utility model, a heavy-duty slider is movably sleeved inside the heavy-duty track, a connecting column is fixedly installed on the bottom surface of the heavy-duty slider, a side plate is installed on one side of the main support tube, a fixing hole is opened on the top surface of the side plate, a fourth support tube is fixedly installed on the bottom surface of the side plate, and two bearings are fixedly sleeved on the inner circular wall of the fourth support tube, and the bearings are fixedly sleeved with the connecting column.

[0008] As a further embodiment of this utility model, a reduction motor is fixedly installed on the bottom surface of the fourth support tube, and the top surface of the drive shaft of the reduction motor is fixedly installed with the connecting column.

[0009] As a further embodiment of this utility model, a limiting component is fixedly installed on the bottom surface of the second threaded rod.

[0010] As a further embodiment of this utility model, two rectangular grooves are respectively opened on both sides of the second slide, both sides of the mounting slide, and both sides of the first slide, and two rotating wheels are installed inside the rectangular grooves.

[0011] As a further embodiment of this utility model, a wireless controller module is fixedly installed on one side of the main support tube, and the wireless controller module is electrically connected to the second drive motor, the third drive motor, the first drive motor and the geared motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a three-section lifting structure consisting of a main support tube, a second support tube, and a third support tube. In conjunction with a first drive motor, a third drive motor, and a second drive motor, the corresponding first threaded rod, second threaded rod, and third threaded rod are driven respectively, converting the rotational motion into the linear motion of the first slide, the second slide, and the mounting plate, which greatly expands the lifting and adjustment range of the lighting equipment. At the same time, no manual intervention is required, making it especially suitable for high-altitude installation scenarios. This not only improves the adjustment efficiency but also avoids the safety risks of high-altitude operations.

[0013] 2. This utility model achieves lateral movement of the lighting equipment through the cooperation of heavy-duty sliders and heavy-duty rails; the connecting column is driven to rotate by a geared motor, and in conjunction with the bearing structure inside the fourth support tube, the main support tube and the mounting plate are driven to rotate horizontally as a whole, forming a multi-dimensional adjustment mode of "lateral movement, vertical lifting and lowering, and horizontal rotation" to adapt to the needs of lighting at different angles; by using heavy-duty rails and high-strength support tubes as the core load-bearing structure, and by setting wheels on both sides of the first slide, the second slide and the mounting plate, the friction between the slide and the support tube is reduced and the sliding stability is improved, thus reducing the sliding resistance.

The adjustment assembly includes: a main support tube 4, disposed on the bottom surface of the heavy-duty track 1; a first slide 9 movably sleeved inside the main support tube 4; a first threaded hole on the top surface of the first slide 9; a first threaded rod 8 threadedly connected to the inner circular wall of the first threaded hole; a first drive motor 7 fixedly mounted on the bottom surface of the main support tube 4; the top surface of the drive shaft of the first drive motor 7 fixedly mounted to the first threaded rod 8; and a first drive motor 7 fixedly mounted on one side of the first slide 9. There is a second support tube 5, and a second slide 12 is movably sleeved inside the second support tube 5. The top surface of the second slide 12 has a second threaded hole, and the inner circular wall of the second threaded hole is threaded with a second threaded rod 11. A third support tube 6 is fixedly installed on one side of the second slide 12. The third support tube 6 is movably sleeved with the mounting slide 2. The top surface of the mounting slide 2 has a third threaded hole, and the inner circular wall of the third threaded hole is threaded with a third threaded rod 14. The top surfaces of the third support tube 6 and the second support tube 5 are respectively fixedly installed with a second drive motor 10 and a third drive motor 13. The drive shafts of the second drive motor 10 and the third drive motor 13 are respectively fixedly installed with the third threaded rod 14 and the second threaded rod 11.

[0020] In this embodiment, a heavy-duty slider 3 is movably sleeved inside the heavy-duty track 1. A connecting column 18 is fixedly installed on the bottom surface of the heavy-duty slider 3. A side plate 15 is installed on one side of the main support tube 4. A fixing hole 16 is opened on the top surface of the side plate 15. A fourth support tube 17 is fixedly installed on the bottom surface of the side plate 15. Two bearings 19 are fixedly sleeved on the inner circular wall of the fourth support tube 17. The bearings 19 are fixedly sleeved with the connecting column 18. A reduction motor 20 is fixedly installed on the bottom surface of the fourth support tube 17. The top surface of the drive shaft of the reduction motor 20 is fixedly installed with the connecting column 18. A limit member 21 is fixedly installed on the bottom surface of the second threaded rod 11. Two rectangular slots are opened on both sides of the second slide table 12, both sides of the mounting slide plate 2, and both sides of the first slide table 9. Two rotating wheels 22 are installed inside the rectangular slots. A wireless controller module is fixedly installed on one side of the main support tube 4. The wireless controller module is electrically connected to the second drive motor 10, the third drive motor 13, the first drive motor 7, and the reduction motor 20.

[0021] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: In use, the heavy-duty track 1 is first installed at the installation position on the top of the room. The heavy-duty slider 3 and the mounting plate 2 adopt the existing conductive transmission technology, and the wireless controller module is powered through the wire. The existing technology (a digital control track frame for a lighting system, announcement number: CN211502467U) is used to enable the heavy-duty slider 3 to move laterally inside the heavy-duty track 1. After installation, the lighting equipment is connected to the mounting plate 2. The bottom of the mounting plate 2 is provided with a connector adapted to the lighting equipment.

[0022] Therefore, when the lighting equipment needs to be raised or lowered, the first drive motor 7, the third drive motor 13, and the second drive motor 10 are activated to drive the first threaded rod 8, the second threaded rod 11, and the third threaded rod 14 connected to each other, thereby converting the rotational motion into linear motion. This causes the first slide 9, the second slide 12, and the mounting plate 2 connected to them to move up and down, allowing the mounting plate 2 to adjust the height of the lighting equipment. Through three-stage lifting and lowering adjustment, manual adjustment is not required, while the range of vertical movement is increased. Furthermore, the overall rigidity is strong, preventing significant swaying and greatly expanding the lifting and lowering adjustment range of the lighting equipment. At the same time, no manual intervention is required, making it particularly suitable for high-altitude installation scenarios, improving adjustment efficiency and avoiding the safety risks of high-altitude operations.

[0023] By using the geared motor 20, the drive shaft of the geared motor 20 is connected to the connecting column 18. The rotation of the drive shaft causes the motor to rotate in the opposite direction, thereby causing the fourth support tube 17 to rotate horizontally under the support of the bearing 19 and the connecting column 18. This, in turn, causes the main support tube 4, the mounting slide plate 2, and the lighting equipment to rotate and adjust, forming a multi-dimensional adjustment mode of "lateral movement, vertical lifting, and horizontal rotation" to meet the precise positioning requirements in complex lighting scenarios. At the same time, by using existing technology (announcement number: CN211502467U), the heavy-duty slider 3 can move laterally inside the heavy-duty track 1, thereby allowing the lighting equipment to move laterally. The adjustment modes are multiple and quite practical.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
