Abstract
Description
Technical Field
[0001] This invention relates to the field of stage equipment, and more particularly to a functional frame for a stage cabin. Background Technology
[0002] Stage containers typically have two forms: a container form and a flat stage form. In the container form, the panels usually close together to form a hexahedron, while in the flat stage form, all the panels can be unfolded into a single plane. Stage containers can have different states, including a transport state, a working state, and a ground-placed state. In the transport state, the stage container is placed on a transport vehicle (for convenience, this document uses "vehicle" to refer to the transport vehicle, although those skilled in the art will understand that transport vehicles are not limited to vehicles). In the working state, the stage container has been unloaded from the vehicle and is held at a certain height above the ground, ready to be unfolded into a flat stage for use. In the ground-placed state, the stage container is placed on the ground. Using the stage container requires transitions between these states. Transitioning from the transport state to other states involves unloading the stage container from the vehicle; transitioning from other states to the transport state involves placing the stage container onto the vehicle, i.e., enabling the stage container to be loaded and unloaded. Transitioning from other states to the ground-placed state involves placing the stage container on the ground, i.e., enabling the stage container to be placed on the ground. Transitioning from other states to the working state also involves changes in the container's height. In summary, stage modular units require lifting and lowering during transportation, operation, and placement on the ground. Existing technologies typically employ specialized lifting mechanisms to grip the individual panels of the modular unit. However, this method exerts forces on the panels, potentially damaging the unit's structure. Furthermore, this mechanism only allows for individual lifting and lowering, failing to provide support for the panels. There is a need in the art to develop a mechanism that consistently meets the requirements of allowing the stage modular unit to be loaded onto and unloaded from transport vehicles without external tools and placed entirely on the ground after folding, while also providing support for the panels when unfolded. Summary of the Invention
[0003] To address the aforementioned technical problems in the existing technology, the present invention provides a functional frame for a stage cabin, which can meet the requirements of transporting the stage cabin onto and off vehicles without the aid of external tools and placing it on the ground as a whole after the stage cabin is closed, and can also serve as a support between the cabin panels and the ground after it is unfolded.
[0004] This invention provides a functional frame for a stage cabin. The cabin panel includes a base plate, a pair of side plates, a pair of top plates, and a pair of end plates. The cabin panel has a closed state and an unfolded state. In the closed state, the base plate, side plates, top plates, and end plates are combined into a hexahedron. In the unfolded state, the cabin panel is coplanar. It includes at least one pair of side plate lifting frames symmetrically arranged on the left and right sides of the base plate, and a pair of end plate frames symmetrically arranged at the front and rear ends of the base plate. The side plate lifting frame includes a main side frame and a secondary side frame. The bottom end of the main side frame is hinged to one side of the base plate, and the secondary side frame is movably connected to the top end of the main side frame. The end plate frame includes a main end frame and a secondary end frame. The bottom end of the main end frame is hinged to one end of the base plate, and the secondary end frame is movably connected to the top end of the main end frame. The secondary side frame and / or the secondary end frame are provided with a connecting mechanism capable of connecting the secondary side frames of the two side plate lifting frames at each end to the secondary end frames of the corresponding end plate frames. The functional frame has… The folded support state corresponds to the closed state of the cabin panels. In the folded support state, the main side frame is attached to the side panel, the secondary side frame is attached to the top panel, the main end frame is attached to the end panel, and the secondary end frame is attached to the top panel in the first position. The secondary side frame and the corresponding secondary end frame are connected by a connecting mechanism, thus forming the outer skeleton of the stage cabin. The functional frame has an unfolded support state corresponding to the unfolded state of the cabin panels. In the unfolded support state, the secondary side frame and the secondary end frame are disconnected, the side panel lifting frame touches the ground as support, the main side frame flips to be parallel to the bottom panel, the secondary side frame moves to be parallel to the main side frame, the main end frame flips to be parallel to the bottom panel, and the secondary end frame touches the ground in the second position for support.
[0005] Compared with the prior art, the beneficial effects of the embodiments of the present invention are at least as follows:
[0006] 1. After closure, the end plate frame at each end and the two sets of side plate lifting frames on the left and right sides are close to the cabin plate and retracted, connecting at the top of the cabin to form a whole, such as a T-shape. This whole serves as the force-bearing foundation when the cabin is raised and lowered, so that no force is exerted on the cabin plate (except for the bottom plate). This solves the force problem when the lightweight and frameless cabin is raised and lowered as a whole, and can effectively protect the cabin body.
[0007] 2. The side panel lifting frame enables the loading, unloading, and landing of the closed container, and can also be deployed to support the container panels against the ground.
[0008] 3. The end plate frame can realize the overall flipping of the end plates and patch plates at each end, and after unfolding, it serves as a support between the cabin plate and the ground. Attached Figure Description

[0030] In this invention, when a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may not be directly connected to the other devices but may have an intermediary device.

[0031] Stage Container
[0032] The following describes the structure of the stage container. Figure 1 This is a schematic diagram of a stage cabin, showing the arrangement of the cabin panels when it unfolds into a flat stage. Figure 2This is a schematic diagram of the stage cabin, showing the arrangement of the cabin panels when it is closed into a cabin.
[0033] As shown in the figure, this disclosure provides a stage cabin, including a cabin panel. The cabin panel includes: a base plate 1; a pair of side plates 2, symmetrically hinged to the left and right sides of the base plate 1; a pair of top plates 3, each top plate 3 hinged to a corresponding side plate 2; a pair of end plates 4, symmetrically hinged to the front and rear ends of the base plate 1; and four patch plate assemblies 5, each end plate 4 having a pair of patch plate assemblies 5 symmetrically hinged to the left and right sides. Each patch plate assembly 5 includes a large patch plate 51, a middle small patch plate 52, and an outer small patch plate 53. The side of 4 is hinged to one side of the large patch 51, the other side of the large patch 51 is hinged to one side of the middle small patch 52, the other side of the middle small patch 52 is hinged to one side of the outer small patch 53, each patch assembly 5 can be unfolded to be coplanar with the end plate and can be closed into a small triangular prism shape. When the two patch assemblies 5 on both sides of the end plate 4 are closed, the two middle small patch 52 are opposite each other, and the two outer small patch 53 are attached to the end plate 4. Each end plate 4 and the two large patch 51 connected to it are closed into a large triangular prism shape.
[0034] Here, "large patch" refers to the patch relative to "small patch," indicating the relative dimensional relationship between the patches; the large patch is larger than the small patch. Similarly, "large triangular prism" refers to the dimensional relationship after assembly; the large triangular prism has a larger volume than the small triangular prism. It's important to understand that "assembling into a corresponding triangular prism shape" means roughly assembling into a triangular prism shape; considering factors such as the thickness of the actual components, it is not a strictly closed triangular prism.
[0035] like Figure 1 and Figure 2 As shown, the cabin panels have a closed state (folded to form a container) and an unfolded state (unfolded to form a flat stage). Figure 2 As shown, in the closed state, the base plate 1, side plate 2, top plate 3, and end plate 4 combine to form a hexahedron. Side plate 2 and end plate 4 are perpendicular to the base plate 1, and the top plate 3 is perpendicular to both side plate 2 and end plate 4 and parallel to the base plate 1. Each patch plate assembly 5 folds into a small triangular prism shape inside the hexahedron, perpendicular to the base plate 1 and top plate 3, serving as support for the top plate 3. Each end plate 4 and its two connected large patch plates 51 fold into a large triangular prism shape. Figure 1 As shown, in the unfolded state, the panels are coplanar, forming a rectangular platform, with the four patch panel assemblies 5 located at the four corners of the rectangular platform.
[0036] Those skilled in the art can reasonably set the dimensional relationships of the various components based on the concept of this application. In some embodiments, the intermediate small patch 52 and the outer small patch 53 are the same size, which facilitates manufacturing and promotes structural stability. In some embodiments, when the patch assembly 5 is closed, the intermediate small patch 52 is perpendicular to the outer small patch 53. This arrangement helps maintain the stability of the shelter.
[0037] Functional framework for stage shelter
[0038] The functional framework of this application can be applied to any type of stage cabin structure, and is not limited to it. Figure 1 and Figure 2 As shown. For example, the stage container may have more or fewer panels than shown, or it may not have a panel assembly, or it may have a panel assembly with other structures.
[0039] like Figures 5-1 to 5-4 As shown, the functional frame for the stage cabin includes: at least one pair of side panel lifting frames 20 symmetrically arranged on the left and right sides of the base plate 1, and a pair of end plate frames 10 symmetrically arranged at the front and rear ends of the base plate 1. The figure shows two side panel lifting frames 20 arranged on each side of the base plate 1. The side panel lifting frame 20 includes a main side frame 200 and a secondary side frame 240. The bottom end of the main side frame 200 is hinged to one side of the base plate 1, and the secondary side frame 240 is movably connected to the top end of the main side frame 200. The end plate frame 10 includes a main end frame 100 and a secondary end frame 140. The bottom end of the main end frame 100 is hinged to one end of the base plate 1. The secondary end frame 140 is connected to the top end of the main end frame 100 and is movable between a first position and a second position. In the first position, the secondary end frame 140 is perpendicular to the main end frame 100 on a first side of the main end frame. In the second position, the secondary end frame 140 is perpendicular to the main end frame 100 on a second side of the main end frame, with the first side facing the end plate 4 and the second side facing away from the end plate 4. A connecting mechanism is provided on the secondary side frame 240 and / or the secondary end frame 140 to connect the secondary end frame 140 of each end of the end plate frame 10 to the secondary side frames 240 of the adjacent secondary side plate lifting frames 20 on both sides.
[0040] The functional frame has a retractable support state corresponding to the closed state of the cabin panels. In the retractable support state, the side main frame 200 is attached to the side panel 2, the side secondary frame 240 is attached to the top panel 3, the end main frame 100 is attached to the end panel 4, and the end secondary frame 140 is attached to the top panel 3 in the first position. The side secondary frames 240 and the corresponding end secondary frames 140 are connected by a connecting mechanism to form, for example, a T-shaped whole, thus constituting the outer skeleton of the stage cabin. Figure 5-1 , Figure 6-1 As shown, at this point, all components are basically close to their respective cabin panels and retracted.
[0041] The functional frame has an unfolded support state corresponding to the unfolded state of the cabin panel. In the unfolded support state, the side secondary frame 240 and the end secondary frame 140 are disengaged, the side panel lifting frame 20 touches the ground as support, the side main frame 200 flips to be parallel to the bottom plate 1, the side secondary frame 240 moves to be parallel to the side main frame 200, the end main frame 100 flips to be parallel to the bottom plate 1, and the end secondary frame 140 touches the ground for support in the second position. Figures 6-8 to 6-12 The preferred illustration.
[0042] Here, the connecting mechanism can take any suitable structure. In one embodiment, such as... Figure 5-3 and Figure 5-4 As preferably shown, the connecting mechanism includes a connecting slot 260 disposed on the free end side of the side subframe 240, and the end subframe 140 can be embedded in the connecting slot 260 on the side subframe 240.
[0043] In addition, such as Figure 4-1 , Figure 4-3 As shown, a side hook 270 can be provided at the bottom end of the side main frame 200. One end of the side hook 270 is hinged to the bottom end of the side main frame 200, and the hook portion of the other end of the side hook 270 is engaged with one side of the base plate 1. Similarly, as Figure 3-1 , Figure 3-2 As shown, an end hook 170 can be provided at the bottom of the end main frame 100. One end of the end hook 170 is hinged to the bottom of the end main frame 100, and the hook at the other end of the end hook 170 is engaged with one end of the base plate 1. This allows for convenient connection and disassembly.
[0044] In this way, when closed, the end plate frame at each end and the two sets of side plate lifting frames on the left and right sides will form an integral outer frame, solving the stress problem when transporting lightweight and frameless modular containers onto and off vehicles or landing; it can prevent the modular container from being impacted by external shocks, and lock each panel inside the outer frame to prevent shaking during transportation, effectively protecting the modular container. Moreover, when unfolded, it can support the modular container panels.
[0045] The following describes further preferred structures for the end plate frame and the side plate lifting frame.
[0046] Side panel lifting frame
[0047] The side panel lifting frame enables the loading, unloading, and landing of the closed modular container, and can also be deployed to support the container panels against the ground.
[0048] Figure 4-1 and Figure 4-2 These are schematic diagrams of a pair of side plate lifting frames symmetrically arranged on both sides of the base plate. Figure 4-1 The first side panel lifting frame 20a is shown in the figure. Figure 4-2The second side panel lifting frame 20b is shown. The two are symmetrically arranged about the base plate. In the illustrated example, the two are identical except for the symmetrical position of the optional auxiliary plate support 280. They are collectively referred to as side panel lifting frame 20 in this application.
[0049] like Figures 4-1 to 4-15 As shown, the side panel lifting frame 20 includes:
[0050] The side main frame 200 is hinged at its bottom end to one side of the base plate 1;
[0051] Side secondary frame 240, which is movably connected to the top of side main frame 200;
[0052] The lifting assembly 400 includes a main body 402 and a push rod 404, the push rod 404 being extendable and retractable relative to the bottom end of the main body 402;
[0053] The first rotating member 210 has one end hinged to the middle of the side main frame 200 and the other end hinged to the top of the body 402. Here, "middle" refers to any position between the top and bottom of the side main frame 200, and is not limited to the physical midpoint.
[0054] The second rotating member 220 has one end hinged to the bottom end of the side main frame 200 and the other end hinged to the bottom end of the main body 402.
[0055] The first rotating member 210, the second rotating member 220, the main body 402 of the lifting assembly 400, and the portion between the first rotating member 210 and the second rotating member 220 can form a parallelogram. By rotating the first rotating member 210 and the second rotating member 220, the lifting assembly 400 can switch between a folded state and an open state. In the folded state, it is close to the side main frame 200, and in the open state, it is far away from the side main frame 200.
[0056] The main diagonal brace 500 has one end hinged to the top of the main body 402;
[0057] The first auxiliary diagonal bar 300a is hinged to the bottom end of the side main frame 200. Its length is set such that when the main diagonal bar 500 is connected to the first auxiliary diagonal bar 300a, the push rod 404 is retracted to its shortest length and the ground contact end of the push rod 404 is lower than the grounding part of the container.
[0058] The second auxiliary diagonal bar 300b is hinged to the bottom end of the side main frame 200 and is longer than the first auxiliary diagonal bar 300a. It is configured such that when the main diagonal bar 500 is connected to the second auxiliary diagonal bar 300b, the push rod 404 is retracted to its shortest length and the ground contact end of the push rod 404 is higher than the grounding device of the container.
[0059] The third diagonal brace 300c is hinged to the side main frame 200 and is located near the top of the side main frame 200.
[0060] In the retracted support state, the lifting assembly 400 is in a folded state, and the main diagonal bar 500 is not connected to the first auxiliary diagonal bar 300a, the second auxiliary diagonal bar 300b, or the third auxiliary diagonal bar 300c.
[0061] In the extended support state, the lifting component 400 of the side plate lifting frame 20 flips with the side main frame 200, and the main diagonal bar 500 is connected to the third auxiliary diagonal bar 300c so that the main body 402 of the lifting component 400 touches the ground for support.
[0062] The functional frame has a lifting support state corresponding to the closed state of the cabin. In the lifting support state, the side main frame 200 is attached to the side plate 2, the side secondary frame 240 is attached to the top plate 3, the end main frame 100 is attached to the end plate 4, and the end secondary frame 140 is attached to the top plate 3 in the first position. The side secondary frame 240 and the corresponding end secondary frame 140 are connected by a connecting mechanism, thus forming the outer skeleton of the cabin. The lifting assembly 400 is in the open state, and the main diagonal rod 500 is connected to the first auxiliary diagonal rod 300a or the second auxiliary diagonal rod 300b. The lifting of the cabin in the closed state is realized by the extension and retraction of the push rod 404.
[0063] The side panel lifting frame enables the raising and lowering of the modular shelter in its closed state, including height adjustment for getting on and off the vehicle and landing, and can also be deployed to support the shelter panels against the ground. Details will follow.
[0064] Lifting function of the side panel lifting frame
[0065] By utilizing the main diagonal brace 500 in conjunction with the first and second auxiliary diagonal braces, the loading, unloading, and landing functions of the assembled modular container are achieved.
[0066] Specifically, rotating the first rotating member 210 and the second rotating member 220 causes the lifting assembly 400 to be in the open state. At this time, the first rotating member 210, the second rotating member 220, the main body 402 of the lifting assembly 400, and the part between the first rotating member 210 and the second rotating member 220 form a parallelogram. Then, the main inclined rod 500 is connected to the first auxiliary inclined rod 300a or the second auxiliary inclined rod 300b. Then, the height of the cabin is raised or lowered by extending and retracting the push rod 404 of the lifting assembly 400.
[0067] When switching the connection between the main inclined rod 500 and the first auxiliary inclined rod 300a to the second auxiliary inclined rod 300b, or vice versa, the container must first be brought to a height that allows the bottom plate legs 11 on the bottom plate 1 of the container to open. Then, the bottom plate legs 11 are opened, and the push rod 404 is retracted to lower the container so that the bottom plate legs 11 touch the ground for support. The aforementioned switching is performed at this time. After the switching, when the container needs to be raised or lowered, the push rod 404 must first be extended and the bottom plate legs 11 must be retracted. Then, the push rod 404 is extended to bring the container to the required height.

[0111] The unfolding support function of the side panel lifting frame
[0112] By connecting the main diagonal brace 500 with the third auxiliary diagonal brace 300c, the unfolding support function of the side panel lifting frame can be realized. The following mainly combines... Figures 6-1 to 6-12 The steps for transforming a stage container from a container placed on a transport vehicle into a flat stage are described. The steps for transforming a stage container from a flat stage into a container placed on a transport vehicle are the reverse of the aforementioned steps.
[0113] Transforming the stage container from a container form placed on a transport vehicle to a flat stage form includes:
[0114] By rotating the first rotating member 210 and the second rotating member 220, the lifting assembly 400 of the side panel lifting frame 20 is moved from the folded state to the open state, and the main inclined rod 500 and the first auxiliary inclined rod 300a of the side panel lifting frame 20 are connected, as follows. Figure 6-1 As shown, and as Figure 4-5 As shown;
[0115] The push rod 404 of the lifting assembly 400 extends to the ground and then continues to extend to a height that allows the vehicle cabin to separate, enabling the vehicle to drive away. Figure 6-2 As shown, and as Figure 4-6 As shown, vehicle-cabin separation refers to the separation of the vehicle and the container;
[0116] Open the base plate support legs 11 mounted on the base plate 1, and retract the push rod 404 of the lifting assembly 400 so that the base plate support legs 11 touch the ground. Figure 6-3 As shown, and as Figure 4-7 and Figure 4-8 As shown;
[0117] The main inclined rod 500 and the first auxiliary inclined rod 300a of the separation side plate lifting frame 20 are as follows: Figure 6-4 As shown;
[0118] The main end frame 100 of the end plate frame 10 is retracted and flipped from being perpendicular to the base plate 1 to being parallel to the base plate 1. The secondary end frame 140 is moved from the first position to the second position so that it touches the ground to serve as a support column. Figure 6-5 As shown;
[0119] The side main frame 200 of the side panel lifting frame 20 is flipped from being perpendicular to the base plate 1 to being parallel to the base plate 1. At this time, the lifting assembly 400 is also flipped, and the side secondary frame 240 of the side panel lifting frame 20 is flipped from being perpendicular to the side main frame 200 to being parallel to the side main frame 200. Figure 6-6 As shown, and as Figure 4-15 As shown, in this state, since the main inclined rod 500 is not connected to any secondary inclined rod, the lifting assembly 400 can still rotate freely.
[0120] The main inclined rod 500 and the third auxiliary inclined rod 300c of the side plate lifting frame 20 are connected so that the main body 402 of the lifting assembly 400 is grounded and supported. Figure 6-7 As shown, in addition Figure 4-4 The diagram shows the length adjustment element 300c0 of the third diagonal bar 300c, which can adjust its length. For example, the length adjustment element can be a left- or right-hand screw, and the length can be adjusted as needed.
[0121] The side panel 2 and top panel 3 are flipped together, so that the side panel 2 is flipped from being perpendicular to the bottom panel 1 to being parallel to the bottom panel 1 so that it is supported by the side main frame 200; as shown Figure 6-8 As shown;
[0122] The top plate 3 is flipped from being perpendicular to the side plate 2 to being parallel to the side plate 2 so that it is supported by the side secondary frame 240; as follows. Figure 6-9 As shown;
[0123] The end plate 4 and its two side patch plate assemblies 5 are flipped over as a whole, so that the end plate 4 is flipped from being perpendicular to the base plate 1 to being parallel to the base plate 1, and the end plate 4 is supported by the end plate frame 10; Figure 6-10 As shown;
[0124] Each patch plate assembly 5 is unfolded from the inner surface side of the end plate 4 to be coplanar with the end plate 4, such as... Figure 6-12 As shown, this forms a two-dimensional stage.
[0125] Figure 6-11 and Figure 6-12 The ladder support 30 and the ground contact plate support column 40 are optional parts set up to achieve reinforcement support, which will be introduced below.
[0126] In one embodiment, when in the modular cabin configuration, the additional support is concealed within the space formed by the folding of the patch assembly 5, such as the interior of a small triangular prism. The additional support includes a ladder support 30, such as... Figure 7 As shown, one of the patch panels 5 on one side has been removed for clearer display. When transforming the stage cabin from a cabin shape to a flat stage shape, after the end plate 4 is parallel to the base plate 1, the step support 30 is removed and placed in the position where support is needed, as shown. Figure 6-11 As shown, it is placed below the patch panel assembly. Preferably, the ladder support 30 also serves as a ladder for personnel to ascend from the ground to the stage surface. When transforming the stage cabin from a planar stage form to a cabin form, before flipping the end plate 4 and the patch panel assemblies 5 on both sides as a whole to be perpendicular to the base plate 1, the ladder support 30 can be placed in the space formed by the closing of the patch panel assemblies 5.
[0127] In one embodiment, the additional support also includes a ground contact patch support column 40 for supporting the patch assembly 5. In the modular shelter configuration, the ground contact patch support column 40 is placed within the ladder support 30, as shown below. Figure 7 As shown. When transforming the stage cabin from a cabin shape to a flat stage shape, after the end plate 4 is parallel to the base plate 1, the ground contact plate support column 40 is taken out and placed in the position corresponding to the unfolded plate assembly 5, as shown. Figure 6-12 As shown. When transforming the stage cabin from a flat stage shape to a cabin shape, before flipping the end plate 4 and the supplementary plate assemblies 5 on both sides as a whole to be perpendicular to the base plate 1, the step support 30 can be placed in the space formed by the closing of the supplementary plate assemblies 5, and then the ground-contact supplementary plate support column 40 can be placed in the step support 30.
[0128] In one embodiment, a supplementary plate support 280 is hinged to one side of the main side frame 200. In the retracted support state and the lifting support state, the supplementary plate support 280 is in a folded position, such as... Figure 4-13 , Figure 6-1 , Figure 6-2 As shown; in the deployed support state, the patch plate support 280 rotates to the open position to support the patch plate assembly 5, as shown. Figure 4-15 , Figure 6-6 , Figure 6-11 As shown. When transforming the stage cabin from a cabin shape to a flat stage shape, after the side main frame 200 flips from being perpendicular to the base plate 1 to being parallel to the base plate 1, the auxiliary plate support 280 is rotated to the open position, as shown. Figure 4-15 , Figure 6-6 , Figure 6-11 As shown. When transforming the stage container from a flat stage shape to a container shape, the supplementary support 280 is rotated back to the folded position. The supplementary support 280 can adopt any suitable structure, such as... Figure 4-15 Preferably, the supplementary support member 280 includes two support plates 2800 and a connecting rod 2801. One end of the two support plates 2800 is hinged to the side main frame 200, and the other end is connected by the connecting rod 2801. In the folded position, the two support plates 2800 are close to the side main frame 200, and in the open position, the two support plates 2800 are perpendicular to the side main frame 200.
[0129] During the transformation of the stage cabin from a flat stage shape to a cabin shape, after the side panel lifting frames on each side are flipped and retracted so that their secondary side frames are against the top panel, the end panel frames are flipped and retracted so that their end side frames are embedded in the connecting slots on the secondary side frames of the side panel lifting frames. At this point, the end side frames and the secondary side frames are connected to form a T-shaped integral structure. This method is very simple, reliable, and easy to operate.
[0130] End plate frame 10
[0131] The end plate frame 10 allows for the flipping of the end plates and patch plate assemblies (if any) at each end, and serves as a support between the cabin deck and the ground when unfolded.
[0132] Next, combine Figures 3-1 to 3-8Describe the end plate frame. As shown in the figure, the end plate frame 10 includes: a main end frame 100, the bottom end of which is hinged to one end of a base plate 1; a secondary end frame 140, which is connected to the top end of the main end frame 100 and is movable between a first position and a second position. In the first position, the secondary end frame 140 is perpendicular to the main end frame 100 on a first side of the main end frame; in the second position, the secondary end frame 140 is perpendicular to the main end frame 100 on a second side of the main end frame, with the first side facing the end plate 4 and the second side facing away from the end plate 4; a lead screw 102, which is mounted perpendicularly to the end edge of the base plate 1 on the main end frame 100; a nut 104, which is mounted on the lead screw 102; a first rod 110, the first end of which is hinged to the nut 104; a second rod 120, the first end of which is hinged to the second end of the first rod 110; and a third rod 130, the first end of which is hinged to the main end frame 100. The third rod is positioned closer to the base plate 1 than the first rod 110 on the frame 100. The second end of the third rod is hinged to the second end of the second rod 120. A second guide 150 is provided at the hinge point between the third rod 130 and the second rod 120. The second guide 150 moves in the second track groove 152, which is fixed to the outer surface of the end plate 4. A locking tongue device 122 is provided on the first rod 110 and / or the second rod 120. It has a locked state and an unlocked state. In the locked state, the first rod 110 and the second rod 120 are locked into a straight rod, so that the first end of the first rod 110, the second rod 120, the third rod 130, and the portion between the first end of the third rod 130 and the first end of the first rod 110 form a triangle. In the unlocked state, the first rod 110 can rotate relative to the second rod 120.
[0133] The end plate frame 10 has a folded state and a flip-up state, such as Figure 3-2 , Figure 5-1 As shown, in the retracted state, the main end frame 100 is retracted against the end plate 4 to be perpendicular to the bottom plate 1, and the secondary end frame 140 is in the first position, as shown. Figures 3-3 to 3-6 As shown, in the flip-plate state, the end main frame 100 flips to be parallel to the bottom plate 1, the end secondary frame 140 touches the ground and is supported in the second position, the locking tongue device 122 can be in the locked state, and the flip-plate 4 is realized by rotating the lead screw 102.
[0134] In some embodiments, such as Figure 3-8 As shown in the preferred embodiment, the nut 104 is also connected to the first guide member 105, and the end main frame 100 is provided with a first track groove 101 parallel to the lead screw 102, in which the first guide member 105 moves. This facilitates the smooth movement of the nut, and in turn guides the movement of the first rod, the second rod, and the third rod, making the flipping process more stable.
[0135] In some embodiments, the lead screw 102 has an operating connector 103 disposed at the top end of the end main frame 100, such as... Figure 3-5As preferably shown, the lead screw 102 can be rotated by rotating the operating joint 103. This facilitates the operation of the lead screw. The corresponding guide can be a roller, which facilitates the stability of movement. In the figure, for better force distribution, these rods and grooves are arranged in two sets symmetrically.
[0136] The locking tongue device 122 can adopt any structure that can achieve the aforementioned functions. In some embodiments, such as Figure 3-8 As shown in the enlarged view, the locking tongue device 122 includes a socket 1220, a locking tongue 1221, and a compression spring 1222. The socket 1220 is located on the first lever 110, and the locking tongue 1221 and compression spring 1222 are located on the second lever 120. The compression spring 1222 can press the locking tongue 1221 into the socket 1220 to lock the locking tongue device 122, as shown by part B in the figure. In the unlocked state, the locking tongue 1221 disengages from the socket 1220, as shown by part A in the figure. This structure is very ingenious; when it is necessary to unlock, the locking tongue 1221 can be manually pulled out of the socket 1220. Figure 3-7 In this state, the locking tongue device 122 is in the unlocked state indicated by A. Figures 3-4 to 3-6 In the state shown, the locking tongue device 122 is in the locked state indicated by B.
[0137] The connection between the main end frame 100 and the secondary end frame 140 can adopt various structures. For example... Figure 3-3 In a preferred embodiment, a mounting groove 116 is provided at the top of the main end frame 100, and the secondary end frame 140 is inserted into the mounting groove 116 and can slide from a first position to a second position relative to the mounting groove 116. A frame lock 160 is provided on the main end frame 100 to lock the secondary end frame 140 relative to the main end frame 100; or, the secondary end frame 140 is hinged to the main end frame 100 so that it can be flipped from the first position to the second position.
[0138] The frame lock 160 can adopt any structure that can achieve the aforementioned functions. In some embodiments, for example, such as Figure 3-3 , Figure 3-4 As shown, the frame lock 160 includes a screw 1600 and a nut 1601. The screw 1600 is rotatably mounted on the main end frame 100. The end faces of both ends of the secondary end frame 140 have notches 1602. The free end of the screw 1600 passes through the notch 1602 at one end of the secondary end frame 140. The nut 1601 is screwed onto the screw 1600 outside the notch 1602. Thus, locking of the secondary end frame 140 can be achieved with this simple structure. Figure 3-2 , Figure 3-3In the first position, the secondary frame 140 is in the first position. The free end of the screw 1600 passes through the notch 1602 of the first end (the locked end in the retracted state) of the secondary frame 140. The nut 1601 is screwed onto the screw 1600 outside the notch 1602, thus achieving locking. To move the secondary frame 140 to the second position, the frame lock 160 needs to be unlocked. Specifically, the nut 1601 is unscrewed, allowing the secondary frame 140 to slide along the mounting groove 116. The secondary frame 140 slides down until the first end (the original locked end) touches the ground. The screw 1600 is rotated so that its free end passes through the notch 1602 of the second end (the locked end in the flip-up state) of the secondary frame 140. The nut 1601 is screwed onto the screw 1601 outside the notch 1602, thus achieving locking again. Figure 3-4 As shown. When it is necessary to move the secondary frame 140 back to the first position, unlock the frame lock 160, slide the secondary frame 140 upward, rotate the screw 1600 so that its free end passes through the notch 1602 at the first end of the secondary frame 140, and then fix it with the nut 1601 to achieve locking.
[0139] The following describes the flipping method of the end plate frame 10. The end plate frame 10 can realize the overall flipping of the end plate and the auxiliary plate assembly (if any) at each end, and after unfolding, it serves as a support for the cabin plate and the ground.
[0140] Remove end plate 4 and supplementary plate assembly (if any) from the position perpendicular to the base plate (e.g. Figure 3-2 (As shown) Flipped to be coplanar with the base plate (as shown) Figure 3-6 The steps (as shown) include: first, retracting and flipping the end main frame 100 from being perpendicular to the base plate 1 to being parallel to the base plate 1, as shown. Figure 3-3 As shown, at this time, the first rod 110 and the second rod 120 are aligned in a straight line, and the locking tongue device 122 is in a locked state to lock the first rod 110 and the second rod 120 into a straight line, so that the first end of the first rod 110, the second rod 120, the third rod 130, and the portion between the first end of the third rod 130 and the first end of the first rod 110 form a triangle;
[0141] Move the end secondary frame 140 from the first position to the second position so that it touches the ground to serve as a supporting column. Figure 3-4 This status is shown;
[0142] Rotating the lead screw 102 causes the nut 104 to move, changing the length of the portion between the first end of the third rod 130 and the first end of the first rod 110. This causes the third rod 130 to rotate, driving the second guide member 150 to move along the second track groove 152, thus achieving the overall flipping of the end plate 4 and the supplementary plate assemblies 5 on both sides. Figure 3-5 This state is shown until the end plate 4 and the bottom plate 1 are coplanar. At this point, the end main frame 100 acts as a supporting crossbar to support the end plate 4 and the auxiliary plate assembly (if any). Figure 3-6 The status is shown.
[0143] By reversing the above process, the hatch can be flipped back to be perpendicular to the bottom plate 1. When retracting the end plate frame 10, the locking tongue device 122 can be placed in the unlocked state. The first end of the first rod 110, the second rod 120, the third rod 130, and the portion between the first end of the third rod 130 and the first end of the first rod 110 form a quadrilateral. Without rotating the lead screw 102, the end main frame 100 can be retracted to be perpendicular to the bottom plate 1. Figure 3-7 The status is shown. Figure 3-7 In the middle, the end plate 4 has been folded back to be perpendicular to the bottom plate 1, and the end secondary frame 140 has moved from the second position back to the first position. The end main frame 100 can be manually flipped back to be perpendicular to the bottom plate 1 and folded back along the direction of the arrow.
[0144] Moving the secondary frame 140 to the second position includes: unlocking the frame lock 160 set on the main frame 100 for locking the secondary frame 140 relative to the main frame 100; sliding the secondary frame 140 within the mounting slot 116 until its original locked end touches the ground; and from... Figure 3-3 and Figure 3-4 This movement can be observed.
[0145] At this point, the endplate frame 10 achieves the overall flipping of the endplates at each end and the auxiliary plate assemblies on both sides, which, after unfolding, serve as supports between the hatch and the ground. This structure allows for labor-saving flipping, and after the endplates and their auxiliary plate assemblies are flipped, they can serve as supports between the endplates and their auxiliary plate assemblies and the ground. During the flipping process, the endplates and auxiliary plate assemblies remain connected to the endplate frame, solving the problem of torque reversal during flipping and ensuring the safe and stable operation of the hatch.
[0146] Using this end plate frame 10, when transforming the stage container from a container form placed on a transport vehicle to a flat stage form, the locking tongue device 122 is locked when the main end frame 100 is flipped from being perpendicular to the base plate 1 to being parallel to the base plate 1. The step of flipping the end plate 4 and the auxiliary plate assemblies 5 on both sides as a whole includes: rotating the lead screw 102, moving the nut 104, changing the length of the portion between the first end of the third rod 130 and the first end of the first rod 110, causing the third rod 130 to rotate, driving the second guide member 150 to move along the second track groove 152, thereby realizing the overall flipping of the end plate 4 and the auxiliary plate assemblies 5 on both sides. Figure 3-5 This state is shown until the end plate 4 and the bottom plate 1 are coplanar. At this point, the end main frame 100 acts as a supporting crossbar to support the end plate 4. Figure 3-6This state is illustrated. When transforming the stage container from a flat stage to a container placed on a transport vehicle, during folding, the locking tongue device 122 is in the unlocked state. The first end of the first rod 110, the second rod 120, the third rod 130, and the portion between the first end of the third rod 130 and the first end of the first rod 110 form a quadrilateral. Without rotating the lead screw 102, the end main frame 100 can be folded to be perpendicular to the base plate 1. It is understood that when the container plate does not include the supplementary plate assembly, the end plate frame 10 is used to achieve the flipping of the end plate at each end; the description above omitting the supplementary plate assembly still applies.
