Description

Technical Field

[0001] This utility model relates to the field of stage lighting, specifically a stage lighting fixture and its fixing structure. Background Technology

[0002] Stage lighting is an essential component of the performance space. It involves the comprehensive visual environment design of the characters and specific scenes according to the development of the plot; it is an artistic creation aimed at visually representing the design intent to the audience. Traditional stage lighting setups involve first constructing a scaffold, then bolting the stage lights to it. Due to the weight of the lights, workers need to hold them with one hand while using tools to install them with the other, making traditional stage lighting installation inconvenient. Furthermore, the scaffolds are typically set high, introducing certain risks during installation. Utility Model Content

[0003] The purpose of this utility model is to provide a stage lighting fixture and its fixing structure to overcome the above-mentioned defects in the prior art.

[0004] According to a fixing structure of the present invention, a fixing plate is provided, and pressure plates are rotatably connected to both ends of the fixing plate. The pressure plates have through grooves extending along their thickness direction. A support plate is provided on the upper side of the fixing plate. The left and right ends of the support plate are respectively connected to two through grooves and slide within them. Guide grooves are provided on the front and rear side walls of the through grooves. Guide posts that slide within the guide grooves are fixed on both the front and rear end faces of the support plate. A screw threaded through the support plate in the vertical direction is internally connected to the support plate. The lower end of the screw is rotatably connected to the fixing plate. An angle is formed between the left and right ends of the support plate and the pressure plates to clamp the truss.

[0005] Furthermore, a lower rubber pad is fixed to the upper surface of the support plate, and the screw passes through the lower rubber pad.

[0006] Furthermore, an upper rubber pad is fixed to the side of the pressure plate away from the screw, and the upper rubber pad is arranged around the through groove.

[0007] Furthermore, a rotating disk is fixed to the upper end of the screw.

[0008] A stage lighting fixture includes any of the above-described fixing structures and a spotlight. The spotlight has a handle fixed to it. The handle is in the shape of an inverted "U". The handle is fixedly connected to the fixing structure. The horizontal part of the handle is fixedly connected to the fixing plate by bolts.

[0009] The beneficial effects of this utility model are as follows: When installing the spotlight, rotating the screw causes the support plate to move upward, thereby causing the two pressure plates to rotate towards the screw until they are in a vertical position. Then, the two pressure plates are inserted upward into the truss. After the lower rubber pad abuts against the truss steel pipe, the screw is reversed, and both pressure plates rotate away from the screw until the upper and lower rubber pads clamp the truss steel pipe, thereby fixing the fixing structure to the truss and increasing the convenience of spotlight installation.

[0017] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are merely simplified descriptions for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description of the utility model is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this stage lighting fixture and its fixing structure are described in detail below:

[0019] One embodiment of this utility model:

[0020] Reference Figures 1-5 This utility model provides a stage lighting fixture and its fixing structure, including a fixing plate 50, with pressure plates 30 rotatably connected to both ends of the fixing plate 50. The pressure plates 30 have through grooves 33 extending along their thickness direction. A support plate 20 is provided on the upper side of the fixing plate 50. The left and right ends of the support plate 20 respectively pass through two through grooves 33 and slide within them. Guide grooves 32 are provided on both the front and rear side walls of the through grooves 33. Guide posts 22 that slide within the guide grooves 32 are fixed to both the front and rear end faces of the support plate 20. A screw 40 extending vertically through the support plate 20 is threaded into the support plate 20. The lower end of the screw 40 is rotatably connected to the fixing plate 50. An angle is formed between the left and right ends of the support plate 20 and the pressure plates 30 to clamp the truss.

[0021] A lower rubber pad 21 is fixed to the upper surface of the support plate 20, and the screw 40 passes through the lower rubber pad 21. The lower rubber pad 21 is made of rubber, thus increasing the friction between the support plate 20 and the frame.

[0022] An upper rubber pad 31 is fixed on the side of the pressure plate 30 away from the screw 40. The upper rubber pad 31 is arranged around the through groove 33, thus increasing the friction between the pressure plate 30 and the frame.

[0023] A rotating disk 41 is fixed to the upper end of the screw 40, and the rotating disk 41 facilitates the rotation of the screw 40.

[0024] A stage lighting fixture includes a spotlight 10, on which a handle 11 is fixed. The handle 11 is in the shape of an inverted "U". The handle 11 is fixedly connected to any of the above-mentioned fixing structures. The horizontal part of the handle 11 is fixedly connected to the fixing plate 50 by bolts 51.

[0025] In use, the truss is first erected, and the rotating disk 41 is rotated to make the screw 40 rotate. Then the fixed support plate 20 moves upward, thereby driving the guide column 22 to move upward. The pressure plate 30 rotates towards the screw 40 with its lower end as the center. According to the distance between the adjacent steel pipes of the truss, the distance between the upper ends of the two pressure plates 30 is adjusted to be greater than the distance between the adjacent steel pipes of the truss and less than the distance between the diagonals of the square frame formed by the steel pipes of the truss.

[0026] Then, push the stage lighting fixture upwards so that the line connecting the upper ends of the two pressure plates 30 coincides with the diagonal of the frame formed by the truss steel pipes, allowing the two pressure plates 30 to pass through the truss. Then rotate the stage lighting fixture so that the line connecting the upper ends of the two pressure plates 30 is perpendicular to the truss steel pipes. At this point, the two pressure plates 30 can be directly placed on the truss steel pipes. Then reverse the rotating disc 41 so that the two pressure plates 30 rotate away from the screw 40 until the upper rubber pad 31 and the lower rubber pad 21 clamp the truss steel pipes, thereby fixing the stage lighting fixture on the truss.

[0027] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
