Description

Technical Field

[0001] This utility model relates to a stage, and more particularly to a lifting stage device. Background Technology

[0002] During stage performances, a stage frame is typically erected. Traditional stage frames are fixed structures, limiting performers to fixed positions. With the increasing diversity of stage performance formats, some stage frames are now height-adjustable. However, the supporting columns of these frames usually only provide height adjustment support on one side, resulting in poor overall stability. Therefore, there is an urgent need for a height-adjustable stage device with greater support stability. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting stage device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A lifting stage device includes: a base with a lifting drive component, the lifting drive component being driven to connect to a lifting frame, the lifting frame having multiple support points around its center; and a vertical frame surrounding the lifting frame, the vertical frame having multiple support points arranged along its vertical direction, the multiple support points respectively abutting against the bottom of multiple sides of the vertical frame.

[0006] This technical solution has at least the following beneficial effects: The base is placed on the ground, the upright frame is fitted around the lifting frame, and multiple upright frames are arranged vertically to form a column support structure. External structures such as beams used to assemble the stage frame can be connected to this column support structure. At this time, multiple support points formed on the outside of the lifting frame extend to the bottom of an upright frame, providing support from multiple sides of the upright frame. When the lifting drive moves the lifting frame up and down, the entire column support structure can be adjusted up and down. In this way, by using the lifting frame to provide support from multiple sides of the upright frame, the phenomenon of the upright frame swaying during vertical movement is effectively prevented, thereby improving the stability of the stage frame's vertical lifting adjustment.

[0007] As a further improvement to the above technical solution, the lifting frame includes a connecting seat and multiple support rods. The tops of the multiple support rods are respectively connected to the outside of the connecting seat, and a clearance area is formed between the multiple support rods. The top of the lifting drive component extends into the clearance area, and the bottom ends of the multiple support rods are bent away from the clearance area to form hooks, which serve as support fulcrums. The multiple support rods correspond to multiple side wall positions of the frame, and the hooks formed by bending the bottom ends of the multiple support rods serve as support fulcrums, supporting the frame from the bottom of the multiple side walls. The clearance area between the multiple support rods accommodates the lifting drive component. During installation, the top of the lifting drive component extends into the clearance area formed between the multiple support rods, making the overall structure more compact. Furthermore, the lifting drive component applies force to the multiple side wall positions of the frame through the multiple support rods with the connecting seat as the center, further improving the stability of the entire frame's vertical height adjustment.

[0008] As a further improvement to the above technical solution, the outer sides of the multiple support rods are inclined from top to bottom in a direction away from the avoidance area. The inclined outer sides of the support rods form a structure that gradually expands outward from top to bottom. When the upright frame is placed on the outside of the lifting frame from above, the multiple inclined support rods can guide the placement of the upright frame, making it convenient to place the support rods into place quickly and stably.

[0009] As a further improvement to the above technical solution, a reinforcing frame is connected to the base at the periphery of the lifting drive component. The reinforcing frame is located below the lifting frame, and a reinforcing plate is provided between the reinforcing frame and the lifting drive component. The reinforcing frame surrounds the lifting drive frame, and the reinforcing plate connects the reinforcing components to the lifting drive component. This provides enhanced support and fixation for the lifting drive component from multiple directions, effectively preventing instability due to the long length of the lifting drive component.

[0010] As a further improvement to the above technical solution, the reinforcing frame is provided with limiting corner plates corresponding to the corners of the upright frame. A first rotating wheel and a second rotating wheel are rotatably connected to the limiting corner plates. The rotation axes of the first and second rotating wheels are perpendicular to each other, and the first and second rotating wheels respectively abut against the inner wall of the upright frame. The first and second rotating wheels on the limiting corner plates can abut against the two sides of the inner corner of the upright frame, providing support and limiting to the inner corner position of the upright frame in the horizontal and vertical directions. When the upright frame moves up and down, the first and second rotating wheels effectively prevent the upright frame from swaying, further improving the stability of the upright frame during vertical movement.

[0011] As a further improvement to the above technical solution, multiple first and second rotating wheels are respectively arranged at intervals along the vertical direction on the limiting angle plate. The multiple first rotating wheels and multiple rotating wheels can increase the coverage area of ​​the contact with the supporting frame, further improving the stability of the supporting frame's limiting position.

[0012] As a further improvement to the above technical solution, a connecting frame is provided between the reinforcing frame and the limiting corner plate. The reinforcing frame strengthens the support for the limiting corner plate, preventing excessive force from being applied to it during frame movement, thus avoiding deformation and further enhancing the stability of the frame's support and limiting function.

[0013] As a further improvement to the above technical solution, the upright frame includes multiple frame plates arranged around the lifting drive component. Adjacent frame plates are detachably connected, and multiple supporting points abut against the bottom sides of the multiple frame plates. The multiple frame plates surround the lifting frame, forming multiple side walls of the upright frame. During production, the frame plates are used as basic units. During assembly and use, the multiple frame plates can be spliced ​​together to form triangular, quadrilateral, or pentagonal upright frames, etc., according to usage requirements. In this case, the multiple supporting points abut against the bottom sides of the multiple frame plates to provide support, providing stable support for the entire upright frame.

[0014] As a further improvement to the above technical solution, each frame plate is provided with a plug on its top side and a socket on its bottom side corresponding to the position of the plug. In two adjacent upright frames, multiple plugs located in the lower upright frame are respectively inserted into multiple sockets located in the upper upright frame. In two adjacent upright frames, the multiple plugs located in the lower upright frame are respectively inserted into multiple sockets located in the upper upright frame to connect and fix the two upright frames to each other. This allows for quick and convenient assembly, and the overall structure is stable.

[0015] As a further improvement to the above technical solution, positioning heads are respectively provided on the base corresponding to the positions of the multiple inserts. The lowest upright frame can be moved down so that the multiple positioning heads are inserted into the multiple inserts respectively. The base is provided with positioning heads that can support and position the multiple upright frames. When the lifting drive unit drives the entire column support structure downward to the end of its stroke through the lifting frame, the multiple inserts on the bottom side of the lowest upright frame are respectively sleeved on the outside of the multiple positioning heads. By utilizing the cooperation between the positioning heads and the inserts, the entire upright frame support structure can be positioned. Attached Figure Description

[0024] Reference Figure 1 A lifting stage device includes a base 100 and a vertical frame. A lifting drive component 110 is mounted on the base 100, and the lifting drive component 110 is connected to a lifting frame 120. The lifting drive component 110 can move the lifting frame 120 up and down. The lifting drive component 110 can have various structural forms, such as a hydraulic cylinder, an electric screw, or a pneumatic cylinder. Multiple support points 121 are formed around the center of the lifting frame 120. The vertical frame surrounds the lifting frame 120, and multiple vertical frames are arranged along the vertical direction. Naturally, due to the limited height of the lifting frame 120, when there are multiple vertical frames, only one, two, or three vertical frames are located around the lifting frame 120. The multiple support points 121 abut against the bottom of multiple sides of one vertical frame. For example, the multiple support points 121 abut against the bottom of multiple sides of the second vertical frame from below.

[0025] As described above, the base 100 is placed on the ground, and the upright frame is fitted around the lifting frame 120. Multiple upright frames are arranged vertically to form a column support structure. External structures such as beams used to assemble the stage frame can be connected to this column support structure. At this time, multiple support points 121 formed on the outside of the lifting frame 120 extend to the bottom of an upright frame. The multiple support points 121 provide support from multiple sides of the upright frame. When the lifting drive 110 drives the lifting frame 120 to move up and down, it can drive the entire column support structure to adjust its height up and down. In this way, the lifting frame 120 provides support from multiple sides of the upright frame, effectively preventing the upright frame from swaying when moving up and down, thereby improving the stability of the stage frame's vertical adjustment.

[0026] The lifting frame 120 has multiple supporting points 121 extending away from its center, and its structural form is varied. In this embodiment, such as... Figure 2As shown, the lifting frame 120 includes a connecting seat 122 and a plurality of support rods 123. The tops of the plurality of support rods 123 are respectively connected to the outside of the connecting seat 122. A clearance area is formed between the plurality of support rods 123. The top of the lifting drive component 110 extends into the clearance area. The bottom ends of the plurality of support rods 123 are respectively bent in a direction away from the clearance area to form hooks. The plurality of hooks are the supporting fulcrums 121. In practical applications, the number of support rods 123 corresponds to the number of side walls of the frame. For example, when the frame is quadrilateral, the number of support rods 123 is also four. At this time, the four support rods 123 extend to the bottom of the four side walls of the frame respectively. Multiple support rods 123 correspond to multiple side wall positions of the frame. The hooks formed by bending the bottom ends of the multiple support rods 123 serve as support fulcrums 121, supporting the frame from the bottom of the multiple side walls. A clearance area is formed between the multiple support rods 123 to accommodate the lifting drive component 110. During installation, the top of the lifting drive component 110 is inserted into the clearance area formed between the multiple support rods 123, making the overall structure more compact. Furthermore, the lifting drive component 110 applies force to the multiple side wall positions of the frame through the multiple support rods 123 with the connecting seat 122 as the center, further improving the stability of the entire frame in adjusting its height.

[0027] The support rods 123 can extend vertically in the up-down direction. For example, to better adapt to the internal shape of the frame and facilitate fitting the frame onto the outside of the lifting frame 120, in this embodiment, the outer sides of the multiple support rods 123 are inclined from top to bottom away from the avoidance area. The inclined outer sides of the support rods 123 form a structure that gradually expands outward from top to bottom. When the frame is fitted onto the outside of the lifting frame 120 from above, the multiple inclined support rods 123 can guide the placement of the frame, facilitating the quick and stable placement of the support rods 123 into position.

[0028] Since the lifting drive component 110 is vertically mounted on the base 100, relying solely on the connection between its bottom and the base 100 for fixation results in poor installation stability, especially when the lifting drive component 110 requires a large range of motion and its overall height is higher. Therefore, a structure to improve the installation stability of the lifting drive component 110 can be added at its middle position. In this embodiment, a reinforcing frame 130 is connected to the base 100 around the lifting drive component 110. The reinforcing frame 130 is located below the lifting frame 120, and a reinforcing plate 131 is provided between the reinforcing frame 130 and the lifting drive component 110. The reinforcing frame 130 surrounds the lifting drive frame, and the reinforcing plate 131 connects the reinforcing component to the lifting drive component 110, providing support and fixation for the lifting drive component 110 from multiple directions, effectively preventing instability due to its long length.

[0029] In practical applications, an opening can be provided in the middle of the reinforcing frame 130 to avoid the lifting drive component 110. The lifting drive component 110 extends out of the reinforcing frame 130 from the opening. Multiple reinforcing plates 131 are connected around the lifting drive component 110 in the reinforcing frame 130 at the opening. The lifting drive component 110 and the reinforcing frame 130 are connected to each other through the multiple reinforcing plates 131.

[0030] To further improve the stability of the frame's movement, in this embodiment, the reinforcing frame 130 is provided with limiting corner plates 140 corresponding to the corners of the frame. The limiting corner plates 140 consist of two mutually perpendicular and connected plates, with a first rotating wheel 141 and a second rotating wheel 142 rotatably connected to each limiting corner plate 140. That is, the first rotating wheel 141 and the second rotating wheel 142 are respectively connected to the two plates. The rotation axes of the first rotating wheel 141 and the second rotating wheel 142 are perpendicular to each other, and the first rotating wheel 141 and the second rotating wheel 142 abut against the inner wall of the frame. The first rotating wheel 141 and the second rotating wheel 142 on the limiting corner plates 140 can abut against the two sides of the inner corner of the frame, providing support and limiting the inner corner position of the frame in the horizontal and vertical directions. When the frame moves up and down, the first rotating wheel 141 and the second rotating wheel 142 effectively prevent the frame from swaying, further improving the stability of the frame's up and down movement.

[0031] The number of limiting corner plates 140 on the reinforcing frame 130 can be one or more, such as four. The four limiting corner plates 140 are respectively set at the four corners of the reinforcing frame 130. At this time, the four limiting corner plates 140 are connected to the first rotating wheel 141 and the second rotating wheel 142. Correspondingly, at each corner of the upright frame, the first rotating wheel 141 and the second rotating wheel 142 are respectively used for mutual restraint, which can effectively improve the stability of the position limitation of the upright frame.

[0032] In some embodiments, the number of first rotating wheels 141 and second rotating wheels 142 can be further increased. Specifically, multiple first rotating wheels 141 and multiple second rotating wheels 142 are respectively arranged at intervals along the vertical direction on the limiting angle plate 140. In practical applications, the multiple first rotating wheels 141 and multiple second rotating wheels 142 are staggered vertically. The multiple first rotating wheels 141 and multiple rotating wheels can increase the coverage of the contact with the support frame, further improving the stability of the limiting of the support frame.

[0033] The height of the limiting angle plate 140 can be set to be relatively long to increase the number of positions that can be limited on the frame. Especially when the limiting angle plate 140 protrudes upward beyond the reinforcing frame 130, it is necessary to further increase the stability of the limiting angle plate 140. Specifically, a connecting frame 150 connects the reinforcing frame 130 and the limiting angle plate 140. The reinforcing frame 130 can strengthen the support of the limiting angle plate 140, which helps to prevent the limiting angle plate 140 from deforming due to excessive force applied when the frame shakes, and further enhances the stability of the limiting angle plate for supporting the frame.

[0034] The upright frame can be a frame structure formed by welding multiple rods or plates together. To improve the flexibility and convenience of upright frame production and assembly, the upright frame can be designed as multiple detachable parts. Specifically, the upright frame includes multiple frame plates 210 arranged around the lifting drive component 110. Adjacent frame plates 210 are detachably connected, and multiple supporting points 121 abut against the bottom sides of the multiple frame plates 210 respectively. The multiple frame plates 210 surround the lifting frame 120, forming multiple side walls of the upright frame. During production, the frame plates 210 are used as basic units. During assembly and use, the multiple frame plates 210 can be spliced ​​together to form triangular, quadrilateral, or pentagonal upright frames, etc. In this case, the multiple supporting points 121 abut against the bottom sides of the multiple frame plates 210 to provide support and stable support for the entire upright frame.

[0035] There are several ways to detachably connect the two frame plates 210. For example, a hinge seat is provided on one side of the frame plate 210 and a rotating seat is provided on the other side of the frame plate 210. When it is necessary to connect the two frame plates 210 to each other, the hinge seat on one frame plate 210 is matched and aligned with the rotating seat on the other frame plate 210, and then a rotating shaft is inserted between the hinge seat and the rotating seat to connect the two frame plates 210 to each other. Assembly is convenient. When it is necessary to separate the two frame plates 210 from each other, the rotating shaft can be removed from between the hinge seat and the rotating seat. Depending on the usage requirements, the frame can be designed as a quadrilateral with four frame plates 210 or a pentagon with five frame plates 210, etc.

[0036] When multiple vertical frames are arranged, a detachable connection structure can be provided between two opposing frame plates 210. Specifically, each frame plate 210 has a plug 211 on its top side and a sleeve 212 on its bottom side corresponding to the plug 211. In two adjacent vertical frames, the plugs 211 of the lower frame are inserted into the sleeves 212 of the upper frame. By inserting the plugs 211 of the lower frame into the sleeves 212 of the upper frame, the two vertical frames are connected and fixed together. This assembly is quick and convenient, and the overall structure is stable. In practical applications, each frame plate 210 may have only one plug 211. However, to improve the stability of the connection between the frame plates 210, at least two plugs 211 may be provided on each frame plate 210, for example, two. In this case, the two frame plates 210 are connected by inserting two plugs 211 into two sleeves 212.

[0037] Furthermore, positioning heads 160 are respectively provided on the base 100 at positions corresponding to the plurality of inserts 212. The bottommost upright frame can be moved down so that the positioning heads 160 are respectively inserted into the plurality of inserts 212. The positioning heads 160 provided on the base 100 can support and position the plurality of upright frames. When the lifting drive 110 drives the entire column support structure to move downward to the end of its stroke via the lifting frame 120, the plurality of inserts 212 on the bottom side of the bottommost upright frame respectively engage with the outer side of the plurality of positioning heads 160. By utilizing the cooperation between the positioning heads 160 and the inserts 212, the entire upright frame support structure can be positioned.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
