Description

Technical Field

[0001] This utility model is a hanging device for large stage lighting fixtures, belonging to the field of stage technology. Background Technology

[0002] In large-scale stage construction and lighting setup, the suspender, composed of three interconnected hollow tubes, is the core load-bearing structure. Its lightweight and high-strength characteristics enable it to stably suspend various large stage lighting fixtures, providing reliable support for the stage lighting effects. The stage light itself is typically equipped with a U-shaped frame, which serves as the connection between the light fixture and the suspender. This U-shaped frame must be connected and fixed to one of the hollow tubes in the suspender to ensure the light fixture maintains a stable posture during the performance.

[0003] Due to the movement, vibration, and contact with equipment in stage performances, existing fixing methods require at least two sets of bolts to securely fasten the U-shaped frame to the hollow tube and prevent relative rotation between the U-shaped frame and the hollow tube. This increases the number of fasteners used, and factors such as changes in air humidity, temperature differences from lighting equipment, and exposure to dust and corrosive gases during long-term use accelerate the corrosion of these fasteners. Over time, corrosion or jamming of any set of fasteners can hinder the disassembly of the stage lights. Especially when repairing, replacing, or repositioning the lights is necessary, corroded fasteners are difficult to remove, requiring significant time and manpower. Forced removal can also damage the U-shaped frame or hollow tube, affecting the equipment's reusability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hanging device for large stage lighting fixtures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a hanging device for large stage lighting fixtures, comprising: The hollow tube is provided in three parts, which are arranged in a triangular shape. Multiple reinforcing bars are evenly installed between the three hollow tubes, and multiple perforations are evenly opened on the outer surface of each hollow tube. The stage light has a U-shaped frame connected to its outer surface by two sets of adjusting screws. A round hole that matches the through hole is opened in the middle of one side of the U-shaped frame. A double-ended bolt, which passes through a channel formed by a through hole and a round hole, with nuts threaded to both ends of the double-ended bolt; The support plate is inserted into the U-shaped frame. Both ends of the support plate are equipped with semi-circular sleeves, which are snapped onto the hollow tube with perforations. The double-headed bolts penetrate the support plate.

[0006] Furthermore, two plug-in posts are installed on the side of the support plate facing the U-shaped frame, and two plug-in holes are opened on the side of the U-shaped frame facing the support plate. The two plug-in holes on the U-shaped frame are symmetrically arranged about the through holes, and the plug-in posts pass through the plug-in holes.

[0007] Furthermore, two small holes are provided on one side of the support plate, and one end of the plug is installed in the small holes.

[0008] Furthermore, the outer surface of the plug-in post is machined with external threads, and a straight threaded cylinder that cooperates with the U-shaped frame to limit the angle of the stage lights is threadedly connected to the plug-in post.

[0009] Furthermore, a rubber pad is glued to one end of the straight threaded cylinder, and the rubber pad is in contact with the surface of the stage lamp.

[0010] Furthermore, both ends of the hanger structure formed by the three hollow tubes and multiple reinforcing bars are equipped with connecting plates, and one side of the connecting plate is evenly provided with multiple through holes for inserting bolts.

[0011] Furthermore, bolt holes are provided at both ends of the U-shaped frame, and one end of the adjusting screw passes through the bolt hole and is threadedly connected to the stage light.

[0012] Furthermore, a connecting part is installed at the middle position of the outer surface of the semi-circular sleeve. The connecting part is connected and fixed to the support plate. Under the support of the structure formed by the connecting part and the semi-circular sleeve, there is a gap between the support plate and the hollow tube. A middle hole is opened at the middle position of one side of the support plate, and the double-headed bolt passes through the middle hole.

[0013] The beneficial effects of this utility model are: The semi-circular sleeves at both ends of the support plate are engaged with the hollow tube, forming a two-way limiting structure with the U-shaped frame. With the fastener formed by a single set of double-headed bolts and nuts, relative rotation can be prevented, eliminating the need for multiple sets of fasteners, reducing the number of fasteners used, and lowering the probability of fasteners rusting and jamming. At the same time, under the support of the support plate and semi-circular sleeves, the double-headed bolts are exposed at the part between the support plate and the hollow tube. When the nuts and double-headed bolts cannot be separated normally due to rust, the double-headed bolts can be cut off using the gap between the hollow tube and the support plate, providing a backup method for disassembling the stage lights.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-3 This utility model provides a technical solution: a hanging device for a large stage lighting fixture, comprising hollow tubes 1, three hollow tubes 1 arranged in a triangular pattern, and multiple reinforcing rods 11 evenly installed between the three hollow tubes 1; both ends of the hanging frame structure formed by the three hollow tubes 1 and the multiple reinforcing rods 11 are equipped with connecting plates 12, and one side of the connecting plates 12 is evenly provided with multiple through holes 13 for inserting bolts. By aligning the ends of one set of hanging frames with another set of hanging frames, and connecting the two fitting connecting plates 12 with multiple sets of bolts, the assembly of the two sets of hanging frames is completed. The length of the stage lighting fixture hanging structure can be adjusted according to stage requirements.

[0017] See Figures 1-4A hollow tube 1 has multiple perforations evenly distributed on its outer surface. A U-shaped frame 21 is connected to the outer surface of the stage lamp 2 via two sets of adjusting screws 22. Bolt holes are provided at both ends of the U-shaped frame 21. One end of the adjusting screw 22 passes through the bolt hole and is threaded to the stage lamp 2, facilitating the adjustment of the relative position between the U-shaped frame 21 and the stage lamp 2, thereby adjusting the angle of the stage lamp 2. A round hole 24 that matches the perforations is provided in the middle of one side of the U-shaped frame 21. A double-ended bolt 4 passes through the channel formed by the perforations and the round hole 24. Nuts 41 are threaded to both ends of the double-ended bolt 4. A support plate 3 is inserted into the U-shaped frame 21. Semicircular sleeves 31 are installed at both ends of the support plate 3 via connecting parts. The semicircular sleeves 31 are snapped onto the hollow tube 1 with perforations. A central hole 36 is provided in the middle of one side of the support plate 3. The double-ended bolt 4 passes through the central hole 36. Under the support of the structure formed by the connecting parts and the semicircular sleeves 31, there is a gap between the support plate 3 and the hollow tube 1. The semi-circular sleeves 31 at both ends of the support plate 3 are snapped onto the hollow tube 1, forming a two-way limiting structure with the U-shaped frame 21. With the help of a single set of double-headed bolts 4 and nuts 41, relative rotation can be prevented, eliminating the need for multiple sets of fasteners, reducing the number of fasteners used, and lowering the probability of rust jamming. At the same time, the double-headed bolts 4 are exposed at the part between the support plate 3 and the hollow tube 1. When the nuts 41 and double-headed bolts 4 cannot be separated normally due to rust, the double-headed bolts 4 can be cut off using the gap between them, providing a backup method for disassembling the stage light 2.

[0018] See Figures 1-4 Two small holes 35 are opened on the side of the support plate 3 facing the U-shaped frame 21, each containing a plug-in post 34. Two plug-in holes 23 are opened on the side of the U-shaped frame 21 facing the support plate 3. These two holes 23 are symmetrically arranged about the through holes, and the plug-in posts 34 pass through the holes 23 to achieve the plug-in connection between the support plate 3 and the U-shaped frame 21. The outer surface of the plug-in post 34 is machined with external threads, and a straight threaded cylinder 32, which cooperates with the U-shaped frame 21 to limit the angle of the stage light 2, is threaded onto the plug-in post 34. A rubber pad 33 is glued to one end of the straight threaded cylinder 32. After the relative position of the stage light 2 and the U-shaped frame 21 is adjusted, the straight threaded cylinder 32 is screwed on to make the rubber pad 33 contact the surface of the stage light 2. The rubber pad 33 prevents the straight threaded cylinder 32 from scratching the surface of the stage light 2. The plug-in posts 34, the straight threaded cylinder 32, and other components cooperate with the U-shaped frame 21 to achieve multi-point support for the stage light 2.
