Description

Technical Field

[0001] This utility model relates to the field of stage structure technology, specifically a stage structure with stable support. Background Technology

[0002] The stage is the space provided in a theater for actors to perform, enabling the audience to focus their attention on the actors' performance and achieve the desired viewing experience.

[0003] In existing technology, a stage typically consists of a platform and legs. A platform has four legs, and each leg has a sleeve. The two ends of a U-shaped steel pipe are inserted into the sleeves on the surfaces of two legs to connect the four legs. After the connection is complete, the plug-in rod at the bottom of the platform is inserted into the plug-in groove at the top of the legs to complete the stage assembly. This stage structure makes the stage assembly and disassembly very convenient and quick.

[0004] However, the existing stage structure lacks lateral support. When people stand on the edge of the stage, the lack of lateral support can easily cause the stage to tip over, resulting in serious performance accidents and even injuries. Utility Model Content

[0005] The purpose of this invention is to provide a stage structure with stable support to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stage structure with stable support, comprising: a stage surface, a stage leg at the bottom end of the stage surface, a swivel joint fixed on the surface of the stage leg, a rotating support rod rotatably connected to the surface of the swivel joint, a telescopic rod mounting groove at the bottom end of the rotating support rod, a telescopic support rod movably inserted into the telescopic rod mounting groove, and a limit component provided between the rotating support rod and the telescopic support rod.

[0007] Preferably, the screw seat has a U-shaped plate structure, and a stop plate is fixed at the end of the screw seat away from the table foot.

[0008] Preferably, the rotating support rod has a rectangular groove structure, the top end of the telescopic support rod has a rectangular rod structure, and a telescopic rod spring is fixed between the top end of the telescopic support rod and the inner wall of the telescopic rod mounting groove.

[0009] Preferably, the limiting component includes: a limiting rod, which is slidably connected in a limiting rod mounting groove, the limiting rod mounting groove being formed on the surface of the telescopic support rod, a guide rail and a limiting groove being formed on the surface of the rotating support rod, the guide rail and the limiting groove being connected, and both ends of the limiting rod being slidably connected in the guide rail.

[0010] Preferably, the limiting rod mounting groove has a rectangular groove structure, and a limiting spring is fixed between one end of the limiting rod and the inner wall of the limiting rod mounting groove.

[0011] Preferably, the limiting rod has a rectangular rod structure, with both ends of the limiting rod extending from the guide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The stage structure with stable support proposed in this utility model, after the stage is assembled, rotates the rotating support rod so that one end of the rotating support rod abuts against the bottom end of the stop plate fixed on the surface of the swivel joint. Then, the telescopic support rod is pulled out a certain distance from the telescopic rod mounting groove opened at the bottom end of the rotating support rod. Then, the telescopic support rod is kept in the state of being pulled out of the telescopic rod mounting groove by the limiting component. At this time, the bottom end of the telescopic support rod abuts against the ground. The supporting force of the ground on the telescopic support rod is transmitted to the rotating support rod through the limiting structure and then to the side of the stage legs through the swivel joint, thereby providing lateral support force for the stage legs and the stage surface installed at the top of the stage legs, preventing the stage from tipping over.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a stage structure with stable support, including: a stage surface 1, a stage leg 2 at the bottom of the stage surface 1, a swivel joint 3 fixed on the surface of the stage leg 2, a rotating support rod 4 rotatably connected to the surface of the swivel joint 3, a telescopic rod mounting groove 7 at the bottom of the rotating support rod 4, a telescopic support rod 6 movably inserted into the telescopic rod mounting groove 7, a limit component between the rotating support rod 4 and the telescopic support rod 6, the swivel joint 3 having a "U"-shaped plate structure, and a stop plate 5 fixed at the end of the swivel joint 3 away from the stage leg 2.

[0023] In actual use, after the stage is assembled, the rotating support rod 4 is rotated so that one end of the rotating support rod 4 abuts against the bottom end of the stop plate 5 fixed on the surface of the swivel joint 3. Then, the telescopic support rod 6 is pulled out a certain distance from the telescopic rod mounting groove 7 opened at the bottom end of the rotating support rod 4. Then, the telescopic support rod 6 is kept in the state of being pulled out of the telescopic rod mounting groove 7 by the limiting component. At this time, the bottom end of the telescopic support rod 6 abuts against the ground. The supporting force of the ground on the telescopic support rod 6 is transmitted to the rotating support rod 4 through the limiting structure and then to the side of the stage leg 2 through the swivel joint 3, thereby providing lateral support force for the stage leg 2 and the platform 1 installed at the top of the stage leg 2, preventing the stage from tipping over.

[0024] Example 2: Based on Example 1, in order to maintain the distance of the telescopic support rod 6 extending out of the telescopic rod mounting groove 7, a limiting structure is provided between the rotating support rod 4 and the telescopic support rod 6. The limiting structure includes: a limiting rod 10, which is slidably connected in the limiting rod mounting groove 9. The limiting rod mounting groove 9 is opened on the surface of the telescopic support rod 6. A guide rail 12 and a limiting groove 13 are opened on the surface of the rotating support rod 4. The guide rail 12 and the limiting groove 13 are connected. The two ends of the limiting rod 10 are slidably connected in the guide rail 12. The limiting rod mounting groove 9 has a rectangular groove structure. A limiting spring 11 is fixed between one end of the limiting rod 10 and the inner wall of the groove of the limiting rod mounting groove 9. The limiting rod 10 has a rectangular rod structure, and the two ends of the limiting rod 10 extend out of the guide rail 12.

[0025] When the telescopic support rod 6 is pulled out from the bottom of the telescopic rod mounting groove 7, the limiting rod 10 in the limiting rod mounting groove 9 moves downward in the guide rail 12. After the limiting rod 10 moves to the bottom of the guide rail 12, the pushing force generated by the compressed limiting spring 11 on the limiting rod 10 pushes both ends of the limiting rod 10 into the limiting groove 13. Without actively moving the limiting rod 10, the limiting rod 10 cannot be pulled out from the limiting groove 13 under the pushing force of the limiting spring 11, thus limiting the limiting rod 10 in the limiting groove 13, achieving the purpose of maintaining the distance of the telescopic support rod 6 extending out of the telescopic rod mounting groove 7.

[0026] Example 3: Based on Example 2, in order to allow the telescopic support rod 6 to retract after disassembling the stage by the distance it extends from the telescopic rod mounting slot 7, thereby reducing the storage space of the stage legs 2, a limiting structure is provided between the rotating support rod 4 and the telescopic support rod 6. The limiting structure includes: a limiting rod 10, which is slidably connected in the limiting rod mounting slot 9. The limiting rod mounting slot 9 is formed on the surface of the telescopic support rod 6. A guide rail 12 and a limiting groove 13 are formed on the surface of the rotating support rod 4. The slot 13 is through, and the two ends of the limiting rod 10 are slidably connected in the guide rail 12. The limiting rod mounting slot 9 has a rectangular groove structure. One end of the limiting rod 10 is fixed between the inner wall of the limiting rod mounting slot 9 and the inner wall of the slot. The limiting rod 10 has a rectangular rod structure. The two ends of the limiting rod 10 extend from the guide rail 12. The rotating support rod 4 has a rectangular groove structure. The top end of the telescopic support rod 6 has a rectangular rod structure. The top end of the telescopic support rod 6 is fixed between the inner wall of the telescopic rod mounting slot 7 and the inner wall of the telescopic rod mounting slot 7.

[0027] When the telescopic support rod 6 is pulled out of the telescopic rod mounting groove 7, the telescopic rod spring 8 fixed between the telescopic support rod 6 and the inner wall of the telescopic rod mounting groove 7 is stretched. After the performance ends and the stage is disassembled, the rotating support rod 4 is rotated back to a state parallel to the stage leg 2. Then, the limiting rod 10 is moved to disengage from the limiting groove 13, thus releasing the limit. The tension generated by the telescopic rod spring 8 on the telescopic support rod 6 under its own elasticity causes the telescopic support rod 6 to retract into the telescopic rod mounting groove 7, and keeps the bottom end of the telescopic support rod 6 flush with the bottom end of the stage leg 2, thereby reducing the storage space of the stage leg 2.

[0028] In actual use, after the stage is assembled, the rotating support rod 4 is rotated so that one end of the rotating support rod 4 abuts against the bottom end of the stop plate 5 fixed on the surface of the swivel joint 3. Then, the telescopic support rod 6 is pulled out a certain distance from the telescopic rod mounting groove 7 opened at the bottom end of the rotating support rod 4. Then, the telescopic support rod 6 is kept in the state of being pulled out of the telescopic rod mounting groove 7 by the limiting component. At this time, the bottom end of the telescopic support rod 6 abuts against the ground. The supporting force of the ground on the telescopic support rod 6 is transmitted to the rotating support rod 4 through the limiting structure and then to the side of the stage leg 2 through the swivel joint 3, thereby providing lateral support force for the stage leg 2 and the platform 1 installed at the top of the stage leg 2, preventing the stage from tipping over. When the telescopic support rod 6 is pulled out from the bottom end of the telescopic rod mounting groove 7, the limiting rod 10 in the limiting rod mounting groove 9 moves downward in the guide rail 12. After the limiting rod 10 moves to the bottom end of the guide rail 12, the thrust generated by the compressed limiting spring 11 on the limiting rod 10 will limit the movement of the stage. Both ends of the positioning rod 10 are pushed into the limiting groove 13. When the limiting rod 10 is not actively moved, it cannot be disengaged from the limiting groove 13 under the pushing force of the limiting spring 11, thus limiting the limiting rod 10 in the limiting groove 13, achieving the purpose of maintaining the distance of the telescopic support rod 6 extending out of the telescopic rod mounting groove 7. When the telescopic support rod 6 is pulled out of the telescopic rod mounting groove 7, the telescopic rod spring 8 fixed between the telescopic support rod 6 and the inner wall of the telescopic rod mounting groove 7 is stretched. After the performance ends and the stage is disassembled, the rotating support rod 4 is rotated back to a state parallel to the stage leg 2, and then the limiting rod 10 is moved to disengage from the limiting groove 13, thus releasing the limitation. The tension generated by the telescopic rod spring 8 on the telescopic support rod 6 under its own elasticity causes the telescopic support rod 6 to retract into the telescopic rod mounting groove 7, and keeps the bottom end of the telescopic support rod 6 flush with the bottom end of the stage leg 2, thereby reducing the storage space of the stage leg 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
