Description

Technical Field

[0001] This invention relates to a stage, and more particularly to a movable folding stage. Background Technology

[0002] For some temporary stages that are not frequently used, they are often designed as movable and foldable stages to facilitate the setup and movement of the stage. To facilitate the movement of the foldable stage, casters are usually installed at the bottom of the stage. However, because of the presence of casters, the casters need to be suspended in the air during use to avoid affecting the stability of the stage.

[0003] Chinese patent CN202117357U discloses an aluminum alloy pulley and rail folding stage. It utilizes the pulley and rail structure of the stage panel to achieve its rotation and limiting functions, and realizes the switching between the unfolded and folded states of the stage panel. The rotation of the chassis wheels is controlled by a lifting handle, which makes the chassis wheels suspended in the air. The lifting handle needs to be manually operated, which is inconvenient. Moreover, the pulley and rail structure is prone to impurities over time, which affects the use of the stage panel.

[0004] Therefore, there is an urgent need for a movable and foldable stage that can facilitate the quick unfolding of the stage panels while ensuring the structural stability of the stage panels in both unfolded and folded states. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a movable folding stage with a stable and reasonable structure, facilitating rapid unfolding of the stage panels. The technical solution adopted by this invention is as follows:

[0041] Advantages of the present application:

[0042] 1. The position of the rolling part is switched by the foot pedal, without the need of manually pulling, and the operation is faster and more convenient. The support part is directly connected with the stage board, and the arrangement of pulleys and sliding rails is omitted, the resistance is reduced, and the stage board is unfolded more smoothly.

[0043] 2. The elastic force of the first spring in the rolling part is first increased and then decreased in the process of rotating the first connecting rod. The elastic force of the first spring is utilized to fix the support leg in the first position or the second position, so that the walking wheel is more reliable and convenient to be retracted.

[0044] 3. The design of the positioning rod realizes the positioning of the two rolling parts in the first position. Especially when the support leg is switched from the second position to the first position, the positioning protrusion on the elastic card enters the positioning hole of the second positioning tube, so as to prevent the contraction between the first positioning tube and the second positioning tube, prevent the total length of the positioning rod from being reduced, and thus ensure the support of the positioning rod to the first connecting rod in the two rolling parts, facilitate the movement of the stage, and prevent the support leg from shaking.

[0045] 4. The second spring in the foot pedal can drive the first push rod to reset after the first push rod pushes the support leg to switch the position, and the foot pedal extends outwardly from the support part, so as to provide sufficient operation space without affecting the arrangement of the stage structure. There is no connection relationship between the foot pedal and the rolling part, and the foot pedal plays a buffering effect when being operated. There is a reaction time from stepping on the foot pedal to the contact between the foot pedal and the rolling part, so as to avoid the position switching of the rolling part caused by accidental stepping.

[0046] 5. The adapter arranged between the cross beam and the stage board can not only relatively move between the adapter and the stage board, but also has small friction, and can fix the position of the adapter when the stage board is unfolded, so as to play a role of inclined support to the stage board, and further improve the stability of the stage board when being unfolded and used.

[0047] 6. The support leg can be detached and stored, so as to reduce the occupied space of the whole stage when the stage board is folded, and facilitate the replacement of the support leg. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0057] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0058] Please refer to the drawings Figures 1-2 The present application provides a movable folding stage, which comprises a support 1, a stage board 3, a rolling piece 4 and a treadle piece 5.

[0059] The support 1 is used for supporting a stage plate 3; the stage plate 3 is rotationally connected to the support 1, and the stage plate 3 can rotate around a first direction to switch the stage plate 3 between a folded state or an unfolded state; a rolling piece 4 is rotationally connected to the support 1, and the rolling piece 4 can rotate around a second direction to move the stage plate 3 in the folded state; a foot piece 5 is rotationally connected to the support 1, and the foot piece 5 can rotate around the second direction to drive the rolling piece 4 to rotate; the first direction is perpendicular to the second direction; in the application, the first direction is a length direction, and the second direction is a height direction; the foot piece 5 drives the position switching of the rolling piece 4, and hands are not needed to be used to pull, so that the operation is faster and more convenient; the support 1 is directly connected to the stage plate 3, and the arrangement of pulleys, sliding rails and other components is omitted, the resistance is reduced, and the stage plate 3 is unfolded more smoothly.

[0060] The support 1 comprises two H-shaped frames 101, two cross beams 102 and four vertical beams 103; the two H-shaped frames 101 are sequentially arranged along the first direction; any cross beam 102 is connected between the two H-shaped frames 101, and the two cross beams 102 are arranged in parallel along the second direction; the four vertical beams 103 are arranged in pairs, one vertical beam 103 of one pair of the vertical beams 103 is connected to one cross beam 102, and the other vertical beam 103 of the one pair of the vertical beams 103 is connected to the other cross beam 102; one vertical beam 103 of the other pair of the vertical beams 103 is connected to one cross beam 102, and the other vertical beam 103 of the other pair of the vertical beams 103 is connected to the other cross beam 102; the vertical beams 103 extend along a third direction; the third direction is perpendicular to the first direction and the second direction; in the application, the third direction is a width direction.

[0061] Please refer to the accompanying drawings Figure 3 The specific connection relationship between the support 1 and the stage plate 3 is that a first fixed block is fixedly arranged on a frame of the stage plate 3, a second fixed block is fixedly arranged on the cross beam 102, and a rotating block is arranged between the first fixed block and the second fixed block, wherein the rotating block is rotationally connected to the first fixed block and the second fixed block through two pin shafts respectively to realize the rotation of the stage plate 3; when the stage plate 3 is folded, the first fixed block connected to the stage plate 3 abuts against the cross beam 102, and the positioning effect of the stage plate 3 is further improved; thereby the height and the volume of the support 1 are reduced to a certain extent.

[0062] As an embodiment of the application, the support 1 and the stage plate 3 can also be rotationally connected through a hinge and the like.

[0063] Please refer to the accompanying drawings Figures 4-5 The rolling piece 4 comprises two feet 401, two walking wheels 402, a first connecting rod 403, a first spring 404 and a positioning rod 405.

[0064] Two feet 401 are respectively rotatably connected to the support 1, and the two feet 401 are sequentially arranged along the second direction and can rotate around the second direction. The feet 401 can be switched between a first position and a second position. When the stage plate 3 is in an unfolded state, the feet 401 can be switched from the first position to the second position, facilitating the use of the stage plate 3. When the stage plate 3 is in a folded state, the feet 401 can be switched from the second position to the first position, facilitating the movement. Specifically, the feet 401 are rotatably connected to the vertical beam 103 through a common rotating part such as a pin shaft, a pin, etc. The first position is that the feet 401 are perpendicular to the mounting surface and the walking wheels 402 can roll along the mounting surface. The second position is that the feet 401 are away from the mounting surface and the walking wheels 402 do not contact the mounting surface. At this time, the H frame contacts the mounting surface and plays a supporting role.

[0065] As an embodiment of the present application, the vertical beam 103 is provided with a slot for limiting the rotation range of the feet 401. Under the limitation of the slot, the feet 401 can only rotate towards the inner side of the vertical beam 103, avoiding the instability of the walking wheels 402 caused by excessive rotation of the feet 401.

[0066] Two walking wheels 402 are respectively connected to the two feet 401, for moving the stage plate 3 in the folded state.

[0067] A first connecting rod 403 extends along the second direction, and the first connecting rod 403 is connected between the two feet 401 to realize the synchronous rotation of the two feet 401.

[0068] One end of the first spring 404 is connected to the first connecting rod 403, and the other end of the first spring 404 is connected to the support 1. The first spring 404 is used to keep the feet 401 in the first position or the second position. Specifically, one end of the first spring 404 is connected to the first connecting rod 403, and the other end of the first spring 404 is connected to the H frame 101. During the rotation of the feet 401, the distance between the first connecting rod 403 and the H frame 101 first increases and then decreases, so that the elastic force of the first spring 404 first increases and then decreases. As a result, the feet 401 are in the first position or the second position under the action of the elastic force of the first spring 404, further reducing the risk of autonomous rotation of the feet 401 and improving the safety in use.

[0069] One end of the positioning rod 405 is rotatably connected to the first connecting rod 403 on one rolling part 4, and the other end of the positioning rod 405 is rotatably connected to the first connecting rod 403 on the other rolling part 4. The positioning rod 405 is used to position the feet 401 in the first position.

[0070] Please refer to the accompanying drawings Figure 1 and 6The positioning rod 405 comprises a first positioning tube 4051 and a second positioning tube 4052, the first positioning tube 4051 is sleeved at one end of the second positioning tube 4052, and the other end of the first positioning tube 4051 is rotationally connected to the first connecting rod 403 on one rolling piece 4, and the other end of the second positioning tube 4052 is rotationally connected to the first connecting rod 403 on the other rolling piece 4;

[0071] The second positioning tube 4052 is provided with an elastic card 4053, and a positioning hole is formed in the surface of the second positioning tube 4052, the elastic card 4053 is provided with a positioning protrusion 4054, and the positioning protrusion 4054 can penetrate the positioning hole; when the positioning protrusion 4054 penetrates the positioning hole under the action of the elasticity of the elastic card 4053 itself, the positioning of the supporting leg 401 in the first position is realized; the elastic card 4053 of the application is a thin iron sheet or other elastic piece, one end of which is clamped and fixed with the second positioning tube 4052, and the other end is provided with the positioning protrusion 4054, and since the positioning protrusion 4054 penetrates the positioning hole to limit the relative sliding between the first positioning tube 4051 and the second positioning tube 4052, the overall length of the positioning rod 405 is positioned, that is, the positions of the two supporting legs 401 are positioned.

[0072] As an embodiment of the application, the first positioning tube 4051 is fixed with a positioning sheet 4055 on the surface, the positioning sheet 4055 is threadedly connected with an adjusting bolt 4056, the adjusting bolt 4056 is coincided with the axis of the positioning hole, when the adjusting bolt 4056 presses the positioning protrusion 4054 into the positioning hole, the limiting relationship between the first positioning tube 4051 and the second positioning tube 4052 is released, and the positioning between the two supporting legs 401 is released, thereby further improving the stability and operation safety of the rolling piece 4.

[0073] In the application, the number of the rolling pieces 4 is two, and the two rolling pieces 4 are sequentially arranged along the first direction; the rolling piece 4 is arranged on the inner side of the H-shaped frame 101, so as to reduce the occupied space.

[0074] Please continue to refer to the accompanying Figures 4-5 The foot pedal 5 comprises a first push rod 501, a second connecting rod 502, a second spring 503, a pedal rod 504 and a pedal plate 505.

[0075] The first push rod 501 is rotationally connected to the supporting piece 1, the first push rod 501 can abut against the first connecting rod 403, and the first push rod 501 is used for pushing the supporting leg 401 to switch from the first position to the second position; specifically, the first push rod 501 is rotationally connected to the vertical beam 103 through a common rotating piece such as a pin shaft or a pin;

[0076] The second connecting rod 502 is connected to the first push rod 501. The second connecting rod 502 extends along the second direction and is used to drive the first push rod 501 to rotate.

[0077] The second spring 503 is connected between the second connecting rod 502 and the support member 1, and is used to reset the second connecting rod 502; specifically, one end of the second spring 503 is connected to the second connecting rod 502, and the other end of the second spring 503 is connected to the H frame 101;

[0078] The pedal 504 is connected to the second connecting rod 502. One end of the pedal 504 extends outward along the first direction toward the support member 1 so as to facilitate foot control of the rotation of the first push rod 501. The outward extension of the pedal 504 puts the pedal 504 in a convenient operating position, reducing the difficulty of operation, and the foot pedal 5 can automatically reset.

[0079] One end of the pedal 505 is rotatably connected to the foot bar 504. The pedal 505 can be rotated so that one end extends out of the support member 1 to facilitate stepping on the pedal 505. In this application, the foot pedal 5 is rotatably connected to the pedal 505 through a pivot. When the pedal 505 is hidden under the H frame 101, it plays a role in preventing accidental contact, avoiding accidental stepping, and improving operational safety. When the foot pedal 5 is rotated so that one end extends out of the H frame, it extends the foot bar 504, which facilitates stepping on the foot bar 504.

[0080] In this application, there are two foot pedals 5, which are connected to two rolling elements 4 respectively. When in use, the two rolling elements 4 can be moved synchronously by operating either foot pedal 5, making the operation simpler and faster.

The connector 2 includes a hinge support 201, a third connecting rod 202, a shell 203, a slider 204, a roller 205, and a positioning bolt 206.

[0082] The hinge support 201 is fixed to the crossbeam 102; one end of the third connecting rod 202 is rotatably connected to the hinge support 201; the outer shell 203 is rotatably connected to the other end of the third connecting rod 202; the slider 204 is mounted on the outer shell 203 and can slide within the frame of the stage board 3; the roller 205 is rotatably connected to the slider 204 and can roll within the frame of the stage board 3 to prevent the slider 204 from detaching from the frame of the stage board 3; the positioning bolt 206 is threadedly connected to the slider 204, and one end of the positioning bolt 206 can penetrate the slider 204 and abut against the frame of the stage board 3 to fix the position of the slider 204 within the frame of the stage board.

[0083] The adapter 2 not only has the function of sliding connection, improving the stability of the stage board 3 during rotation, but also reduces the friction between the stage board 3 and the adapter 2 through the roller 205, so that the rotation of the stage board 3 is smoother, and the positioning bolt 206 increases the relative position between the sliding block 204 and the stage board 3 after the stage board 3 is unfolded, which plays the role of a triangular diagonal brace, further ensuring the structural stability of the stage board 3 during unfolding.
