Description

Technical Field

[0001] This utility model relates to the field of stage equipment, specifically to a movable folding stage. Background Technology

[0002] A stage is a space provided for performers. Traditional stages are usually fixed structures and need to be transported to the site for mobile performances or outdoor activities. They are then manually moved, assembled, and installed, which is time-consuming and labor-intensive. Therefore, there is now a type of mobile stage that can move on the ground, which can reduce the manpower required for stage construction. However, these stages are not foldable, resulting in their large size, large space occupation, and extreme inconvenience in transportation and storage. Or, although they have a certain degree of folding function, the folding operation is complicated and requires manual unfolding and folding, which cannot be completed quickly and cannot meet the needs of rapid construction and disassembly. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figures 1-5 This embodiment provides a movable folding stage, including a tabletop 1 and a base 2. The tabletop 1 includes a fixed part 11 and a movable part 12. The fixed part 11 is hinged to the movable part 12. The fixed part 11 and the base 2 are fixedly connected by several vertical rods 3. The fixed part 11 is provided with a driving device 4 that drives the movable part 12 to rotate upward to unfold and to rotate downward to fold.

[0021] This invention achieves a foldable effect by dividing the platform 1 into a fixed part 11 and a movable part 12 that are hinged to each other. Thus, this invention can reduce the space occupied by folding the platform 1, making it easier to transport and store. Furthermore, the automatic up-and-down rotation of the movable part 12 by the drive device 4 can reduce the workload of unfolding and folding the platform 1, while increasing the speed of unfolding and folding the platform 1, which can meet the needs of rapid stage setup and disassembly.

[0022] See Figure 1 The lower end of the base 2 is rotatably equipped with a walking wheel 21.

[0023] The use of the wheels 21 facilitates the handling of this utility model, and is beneficial for the rapid assembly and disassembly of the stage.

[0024] See Figure 1 , Figure 3 The drive device 4 includes a hydraulic rod 41, a hinge 44, and a hinge rod 45. The bottom end of the cylinder 42 of the hydraulic rod 41 is fixed on the base 2. The top end of the piston 43 of the hydraulic rod 41 is provided with a hinge 44. A hinge rod 45 is provided between the hinge 44 and all the movable parts 12. The upper and lower ends of the hinge rod 45 are respectively hinged to the movable parts 12 and the hinge 44.

[0025] When the piston 43 is driven to move upward, the hinge 44 moves upward and drives the movable part 12 to rotate upward through the hinge rod 45, thus unfolding the tabletop 1. When the piston 43 is driven to move downward, the movable part 12 rotates downward under its own weight and drives the hinge 44 to move downward through the hinge rod 45, thus folding the tabletop 1. Therefore, in this utility model, the automatic unfolding and folding of the tabletop 1 is achieved through the hydraulic rod 41, which has the advantages of simple structure and fast unfolding and folding speed.

[0026] See Figure 1 , Figure 3 The bottom end of the fixing part 11 is provided with a sleeve 13, and the top end of the piston 43 is adapted to slide into the sleeve 13.

[0027] When piston 43 moves upward to drive the platform 1 to unfold, the piston 43 extends a long distance from the cylinder 42 and supports the movable part 12 through the hinge rod 45. Therefore, piston 43 bears a large stress. When the weight of the performer and the placed items on the platform 1 is uneven, it will generate lateral stress on piston 43, which may cause piston 43 to bend. This will cause the movable part 12 where the performer or items are located to tilt, posing a risk that the performer and items will fall off the platform 1. Therefore, in this utility model, a sleeve 13 is provided at the bottom end of the fixed part 11. When piston 43 moves upward to make the movable part 12 rotate to a horizontal state, the upper end of piston 43 is adapted to be inserted into the sleeve 13. The sleeve 13 reduces the degree of bending of piston 43 when it receives lateral stress, thereby ensuring that the movable part 12 is always in a horizontal state and improving the safety of this utility model.

[0028] See Figure 2 The platform 1 is circular, the fixed part 11 is a regular decagon, and ten movable parts 12 are provided and are respectively hinged to each side of the fixed part 11. The movable parts 12 are divided into group A and group B. Adjacent movable parts 12 belong to group A and group B respectively. When the hinge 44 moves downward, the movable part 12 of group A rotates a certain distance first and then the movable part 12 of group B rotates.

[0029] Since the movable part 12 is fan-shaped, when the movable part 12 rotates downward to fold the tabletop 1, if adjacent movable parts 12 rotate simultaneously, there will be interference between the adjacent movable parts 12, causing the movable parts 12 to get stuck and unable to rotate downward. Therefore, in this utility model, the movable parts 12 are divided into two groups, A and B, and adjacent movable parts 12 do not belong to the same group, so that adjacent movable parts 12 can rotate one after another to fold the tabletop 1, thereby solving the problem of adjacent movable parts 12 getting stuck when rotating simultaneously, and ensuring the normal folding operation of the tabletop 1.

[0030] See Figure 1 , Figure 3-5 The hinge 44 includes an upper hinge 46 and a lower hinge 47. The upper hinge 46 and the movable part 12 of group A are connected by a hinge rod 45. The lower hinge 47 and the movable part 12 of group B are connected by a hinge rod 45. An insert rod 48 is slidably disposed inside the top end of the piston 43 of the hydraulic rod 41. The upper end of the insert rod 48 is adapted to be inserted into the sleeve 13. The upper hinge 46 is fixed on the insert rod 48, and the lower hinge 47 is fixed on the piston 43. A spring 49 is disposed between the insert rod 48 and the piston 43. The upper and lower ends of the spring 49 are fixedly connected to the insert rod 48 and the piston 43, respectively.

[0031] When the platform 1 is in the unfolded state, the movable parts 12 of groups A and B are on the same horizontal plane. At this time, the upper hinge 46 abuts against the sleeve 13, the lower sleeve 13 abuts against the upper hinge 46, and the spring 49 is in a compressed state. When the piston 43 is driven to move downward, the lower hinge 47 moves downward at the same time, thereby driving the movable part 12 of group B to rotate downward. At this time, the insert rod 48 and the upper hinge 46 remain stationary under the action of the spring 49. This allows the movable part 12 of group B to rotate a certain distance before the movable part 12 of group A rotates, solving the problem of the movable parts 12 getting stuck when adjacent movable parts 12 rotate simultaneously.

[0032] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
