Description

Technical Field

[0001] The present invention relates to the technical field of stage devices, and in particular to a height-adjustable stage device based on a telescopic structure and an adjustment method thereof. Background Art

[0002] The stage can be a fixed stage or a movable stage with various structural forms, but there are few adjustable and retractable stages. The patent document with application number CN206667836U discloses a retractable stage device, which solves the problem that the common stage device occupies a large area during transportation and achieves the purpose of convenient transportation and handling. Although the stage device can be retracted in the horizontal direction and has the advantages of being easy to transport and assemble, it cannot be quickly adjusted in height when the stage is built or used, which will bring some limitations in use. In the face of different performance venues, there may be different height requirements. If the stage device cannot adjust the height, it may not be able to adapt to certain venues, thereby limiting its scope of use. Especially during the performance, it is necessary to adjust the stage at a certain position to different heights quickly up and down and adjust the retractable changes at the same time. The existing structure with lifting is directly combined, and its structure is not too complicated, or it is difficult to adapt to the horizontal retractable structure. In order to solve the above problems, we have introduced a height-adjustable stage device based on a retractable structure. Summary of the invention

[0003] In order to achieve the above object, the present invention adopts the following technical solutions:

[0004] The cam is an adjustable platform, and the cam is connected to the bottom of the fixing frame by a connecting frame and a sliding plate. The outer side of the sliding plate is slidably connected to the inner part of the fixing frame. The bottoms of the fixing frame and the connecting frame are both provided with a first support column. The bottoms of the first support column are fixedly connected to a base. The tops of the first support column are provided with a storage groove. The interior of the storage groove is slidably connected to a second support column. The tops of the second support columns extend to the tops of the first support columns and are fixedly connected to a mounting plate. The tops of the mounting plate are respectively mounted to the bottoms of the fixing frame and the connecting frame by screws. The bottom of the fixing frame is fixedly connected to a movable plate. One side of the movable plate is slidably connected to a connecting frame. An adjusting component is arranged inside the connecting frame, and the adjusting component is used to drive the fixing frame and the connecting frame to move.

[0005] In a preferred embodiment, the adjustment assembly includes a first rotating rod, which is rotatably connected to the inside of a connecting frame, a motor is arranged on the top of the connecting frame, sprockets are arranged on the outside of the motor output shaft and the outside of the first rotating rod, and a chain is arranged inside the sprocket.

[0006] In a preferred solution, the first rotating rod is slidably connected to the second rotating rod, bolts are arranged inside the first rotating rod and the second rotating rod, and a first bevel gear is arranged at one end of the first rotating rod and the second rotating rod.

[0007] In a preferred solution, a connecting plate is fixedly connected to one side of the first support column, a threaded rod is rotatably connected inside the connecting plate, a second bevel gear is provided at the bottom of the threaded rod, and the first bevel gear is meshed with the second bevel gear.

[0008] In a preferred solution, a sleeve is provided at the bottom of the fixing frame and the connecting frame, the interior of the sleeve is threadedly connected to the outer side of the threaded rod, the top of the sleeve is rotatably connected to a flange block, and the top of the flange block is respectively mounted to the bottom of the fixing frame and the connecting frame by screws.

[0009] In a preferred solution, the outer side of the sleeve is equidistantly fixedly connected to the limit block, the top of the connecting plate is equidistantly fixedly connected to the limit rod, and the outer side of the limit rod is slidably connected to the inner side of the limit block.

[0010] In a preferred solution, a spring is provided between the bottom of the second support column and the bottom of the inner wall of the first support column.

[0011] An adjustment method based on the above stage device is characterized by comprising the following steps:

[0012] 1) When the performance venue is adjusted in height, the sprocket and chain are driven by starting the motor, thereby driving the first rotating rod, the second rotating rod, the bolt and the first bevel gear to rotate. The meshing relationship between the first bevel gear and the second bevel gear will cause the second bevel gear to rotate together with the threaded rod. Since there is a threaded connection between the sleeve and the threaded rod, the sleeve will also rotate accordingly. The movement of the sleeve is restricted by the setting of the limit block and the limit rod so that it can only move in the up and down directions. The movement of the sleeve pushes the fixed frame, the connecting frame and the sliding plate to move upward, and the movable plate slides upward inside the connecting frame. At the same time, when the height adjustment is completed, the second support column will also extend from the storage slot of the first support column, thereby effectively adjusting the height of the stage device. Conversely, the motor is started to rotate in the opposite direction to achieve descent.

[0013] 2) A sliding plate is fixedly connected to one side of the connecting frame, and the outer side of the sliding plate is slidably connected to the inner side of the fixed frame. The fixed frame and the sliding plate are slidably moved and positioned, and the second rotating rod and the first rotating rod are slid and the hole position is limited and positioned by the bolts, so as to achieve lateral telescopic deformation.

[0014] It also includes the following: the stage device is arranged in multiple pieces side by side to form deformation adjustment of stages of different sizes, and a controller is used to connect each of the motors to achieve the needs of unified or separate lifting and lowering adjustment control.

[0015] The present invention has the following advantages:

[0016] A height-adjustable stage device based on a telescopic structure is realized. By adopting an adjustment component controlled by a motor, the device can be flexibly and quickly adjusted in height according to the height requirements of different performance venues, and at the same time can realize deformation adjustment combined with adaptation to lateral expansion and contraction, which greatly expands the applicability and practicality of the stage device. The stage device can be arranged in parallel in multiples to form deformation adjustment of stages of different sizes. A controller is used to connect the motors respectively to achieve unified or separate lifting and lowering adjustment control requirements, so as to improve the use of different performance requirements and different places. It is very practical and improves the efficiency of electric operation.

[0017] The device-based adjustment method is simple and practical, and improves the intelligent control application effect of stage use adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] By setting the adjustment component, when it is necessary to adjust according to the performance venue, the adjustment component is started to drive the fixed frame 1, the connecting frame 2 and the sliding plate 3 to move upward, and the movable plate 25 slides upward inside the connecting frame 9. At the same time, the second support column 7 will extend upward from the storage groove 6 in the first support column 4, thereby adjusting the height of the stage device, so that the device can be flexibly adjusted according to the height requirements of different performance venues, greatly expanding the applicability of the stage device. Through reasonable height adjustment, it can ensure that all audiences have a good viewing angle and enhance the performance experience.

[0028] Reference Figures 1 to 5In a preferred embodiment, the adjustment component includes a first rotating rod 10, which is rotatably connected to the inside of the connecting frame 9, and a motor 11 is arranged on the top of the connecting frame 9, and a sprocket 12 is arranged on the outside of the output shaft of the motor 11 and the outside of the first rotating rod 10, and a chain 13 is arranged inside the sprocket 12; a second rotating rod 14 is slidably connected to the inside of the first rotating rod 10, and bolts 15 are arranged inside the first rotating rod 10 and the second rotating rod 14, and a first bevel gear 16 is arranged at one end of the first rotating rod 10 and the second rotating rod 14; a connecting plate 23 is fixedly connected to one side of the first support column 4, and a connecting plate 23 is fixedly connected to ... The inside of the plate 23 is rotatably connected with the threaded rod 17, and the bottom of the threaded rod 17 is provided with a second bevel gear 18, and the first bevel gear 16 is meshed with the second bevel gear 18; the bottom of the fixed frame 1 and the connecting frame 2 are both provided with a sleeve 19, the inside of the sleeve 19 is threadedly connected to the outside of the threaded rod 17, and the top of the sleeve 19 is rotatably connected with a flange block 20, and the top of the flange block 20 is respectively installed with the bottom of the fixed frame 1 and the connecting frame 2 by screws; the outside of the sleeve 19 is equidistantly fixedly connected to the limit block 21, and the top of the connecting plate 23 is equidistantly fixedly connected to the limit rod 22, and the outside of the limit rod 22 is slidably connected to the inside of the limit block 21;

[0029] The first rotating rod 10 is internally slidably connected with the second rotating rod 14, and bolts 15 are arranged inside the first rotating rod 10 and the second rotating rod 14. The second rotating rod 14 is slidably connected with the first rotating rod 1 to achieve lateral telescopic adjustment, and the bolts 15 are used to limit the hole position.

[0030] When it is necessary to adjust according to the performance venue, by starting the motor 11, the sprocket 12 and the chain 13 are used to drive the first rotating rod 10, the second rotating rod 14, the bolt 15 and the first bevel gear 16 to rotate, and then the meshing relationship between the first bevel gear 16 and the second bevel gear 18 is used to drive the second bevel gear 18 and the threaded rod 17. Since the sleeve 19 and the threaded rod 17 are in a threaded connection relationship, the sleeve 19 on the original side will also rotate. By setting the limit block 21 and the limit rod 22 to limit the sleeve 19, the sleeve 19 can only move up and down, so it will drive the fixed frame 1, the connecting frame 2 and the sliding plate 3 to move upward, and the movable plate 25 will slide upward inside the connecting frame 9. At the same time, the second support column 7 will extend upward from the storage slot 6 in the first support column 4, thereby adjusting the height of the stage device. By designing such a set of height adjustment mechanisms, not only the limitation that the stage device cannot adjust the height is solved, but also multiple benefits are brought, the safety, flexibility and adaptability of the stage are improved, thereby improving the overall use value. Such a design enables the stage device to perform well in a variety of performance occasions and enhance its market competitiveness.

[0031] Reference Figures 1 to 5In a preferred embodiment, a spring 24 is provided between the bottom of the second support column 7 and the bottom of the inner wall of the first support column 4; by providing the spring 24, the second support column 7 is more stable during the up and down movement, making the stage device more stable when adjusting the height.

[0032] Working principle: When in use, when it is necessary to adjust the height according to the performance venue, it can be achieved by starting the motor 11. First, the motor 11 drives the sprocket 12 and the chain 13 to operate, thereby driving the first rotating rod 10, the second rotating rod 14, the bolt 15 and the first bevel gear 16 to rotate. Then, the meshing relationship between the first bevel gear 16 and the second bevel gear 18 will cause the second bevel gear 18 to rotate together with the threaded rod 17. Since there is a threaded connection between the sleeve 19 and the threaded rod 17, the sleeve 19 will also rotate accordingly. At the same time, through the setting of the limit block 21 and the limit rod 22, the movement of the sleeve 19 is restricted so that it can only move in the up and down directions. In this way, the movement of the sleeve 19 will push the fixed frame 1, the connecting frame 2 and the sliding plate 3 to move upward. In addition, the movable plate 25 will slide upward inside the connecting frame 9. At the same time, when the height adjustment is completed, the second support column 7 will also extend from the storage slot 6 of the first support column 4, thereby effectively adjusting the height of the stage device. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0033] An adjustment method based on the above stage device is characterized by comprising the following steps:

[0034] 1) When the performance venue is adjusted in height, the sprocket and chain are driven by starting the motor, thereby driving the first rotating rod, the second rotating rod, the bolt and the first bevel gear to rotate. The meshing relationship between the first bevel gear and the second bevel gear will cause the second bevel gear to rotate together with the threaded rod. Since there is a threaded connection between the sleeve and the threaded rod, the sleeve will also rotate accordingly. The movement of the sleeve is restricted by the setting of the limit block and the limit rod so that it can only move in the up and down directions. The movement of the sleeve pushes the fixed frame, the connecting frame and the sliding plate to move upward, and the movable plate slides upward inside the connecting frame. At the same time, when the height adjustment is completed, the second support column will also extend from the storage slot of the first support column, thereby effectively adjusting the height of the stage device. Conversely, the motor is started to rotate in the opposite direction to achieve descent.

[0035] 2) A sliding plate is fixedly connected to one side of the connecting frame, and the outer side of the sliding plate is slidably connected to the inner side of the fixed frame. The fixed frame and the sliding plate are slidably moved and positioned, and the second rotating rod 14 is slidably connected to the first rotating rod 10, and the hole position is limited and positioned by the bolt 15, so as to achieve lateral telescopic deformation.

[0036] It also includes the following: the stage device is arranged in multiple pieces side by side to form deformation adjustment of stages of different sizes, and a controller is used to connect each of the motors to achieve the needs of unified or separate lifting and lowering adjustment control.

[0037] The connection circuit between the controller and the motor and the control principle are existing technical structures and will not be further detailed here.

[0038] The above embodiment realizes a height-adjustable stage device based on a telescopic structure. By adopting an adjustment component controlled by a motor, the device can be flexibly and quickly adjusted in height according to the height requirements of different performance venues, and can also realize deformation adjustment combined with horizontal expansion and contraction, which greatly expands the applicability and practicality of the stage device. The stage device can be arranged side by side in multiple shapes to form deformation adjustment of stages of different sizes.
