The ladder support 30 and the ground contact patch support column 40 of fig. 6-11 and 6-12 are optional parts provided for reinforcement support, as will be described below.

In one embodiment, the additional support is hidden in the space formed by the folding of the patch panel assemblies 5 in the shelter configuration, such as the interior of a small triangular prism, and includes a ladder support 30, shown in fig. 7, with one of the patch panel assemblies 5 on one side removed for clarity. When changing the stage shelter from the shelter configuration to the planar stage configuration, after the end plates 4 are parallel to the bottom plate 1, the ladder support 30 is taken out and placed in a position where support is required, as shown in fig. 6-11, as placed under the patch assembly. Preferably, the ladder support 30 also serves as a ladder for personnel to step up the stage surface from the ground. When the stage shelter is changed from the planar stage form to the shelter form, the ladder support 30 can be placed in the space formed by folding the supplementary board assemblies 5 before the end board 4 and the supplementary board assemblies 5 on the two sides of the end board are integrally turned to be vertical to the bottom board 1.

In one embodiment, the additional support further includes a ground contact patch support column 40 for supporting patch panel assembly 5.

When the stage shelter is changed from the planar stage form to the shelter form, before the end plate 4 and the complement plate assemblies 5 on the two sides of the end plate are integrally turned to be vertical to the bottom plate 1, the ladder support 30 can be placed in a space formed by folding the complement plate assemblies 5, and then the ground contact complement plate support columns 40 are placed in the ladder support 30.

In one embodiment, one side of the side main frame 200 is hinged with a patch support 280, and the patch support 280 is in a folded position in a folded support state and a lifted support state, as shown in fig. 4-13, 6-1, 6-2, etc.; in the unfolded support state, the patch panel support 280 is rotated to the open position for supporting the patch panel assembly 5, as shown in fig. 4-15, 6-6, 6-11. When the stage shelter is changed from the shelter form to the planar stage form, the patch support 280 is rotated to the open position after the side main frames 200 are turned from being perpendicular to the floor 1 to being parallel to the floor 1, as shown in fig. 4 to 15, 6 to 6, and 6 to 11. When the stage shelter is changed from the planar stage configuration to the shelter configuration, the patch support 280 is rotated back to the folded position. The patch support 280 may take any suitable structure, and as is preferred in fig. 4-15, the patch support 280 includes two stay plates 2800 and a connection rod 2801, one end of each stay plate 2800 is hinged to the side main frame 200, and the other end is connected by the connection rod 2801. In the folded position, the two gussets 2800 are closed on the side main frame 200, and in the unfolded position, the two gussets 2800 are perpendicular to the side main frame 200.

In the process of changing the stage shelter from the planar stage form to the shelter form, after the side plate lifting frames on each side are overturned and folded to enable the side sub-frames to be close to the top plate, the end plate frames are overturned and folded to enable the end side frames to be embedded into the connecting groove pieces on the side sub-frames of the side plate lifting frames, and at the moment, the end sub-frames and the side sub-frames are connected to form a T-shaped whole. This is very simple, robust and easy to operate.

Terminal board frame 10

The end panel frame 10 enables the end panel and the complementary panel assembly (if any) at each end to be flipped over and to serve as a support for the deck and floor after deployment.

The end plate rack is described next in connection with fig. 3-1 to 3-8. As shown, the end plate frame 10 includes: an end main frame 100 whose bottom end is hinged to one end of the base plate 1; an end sub-frame 140 coupled to the top end of the end main frame 100, and movable between a first position in which the end sub-frame 140 is perpendicular to the end main frame 100 on a first side of the end main frame, and a second position in which the end sub-frame 140 is perpendicular to the end main frame 100 on a second side of the end main frame, the first side facing the end plate 4 and the second side facing away from the end plate 4; a screw 102 mounted on the end main frame 100 perpendicularly to the end edge of the base plate 1; a lead screw nut 104 mounted on the lead screw 102; a 1 st rod 110, a first end of which is hinged to the lead screw nut 104; a 2 nd bar 120 having a first end hinged to a second end of the 1 st bar 110; a 3 rd bar 130 having a first end hinged to the end main frame 100 at a position closer to the bottom plate 1 than the 1 st bar 110, a second end of the 3 rd bar hinged to a second end of the 2 nd bar 120, and a second guide 150 provided at the hinge of the 3 rd bar 130 and the 2 nd bar 120, the second guide 150 moving in a second rail groove 152, the second rail groove 152 being fixed to the outer surface of the end plate 4; the locking tongue means 122 is provided on the 1 st bar 110 and/or the 2 nd bar 120, and has a locked state in which the 1 st bar 110 and the 2 nd bar 120 are locked as a straight bar, so that a portion between the first ends of the 1 st bar 110, the 2 nd bar 120, the 3 rd bar 130, and the 3 rd bar 130 to the first end of the 1 st bar 110 forms a triangle, and an unlocked state in which the 1 st bar 110 can relatively rotate with respect to the 2 nd bar 120.

The end plate frame 10 has a folded state in which the end main frame 100 is folded against the end plate 4 to be perpendicular to the bottom plate 1, as shown in fig. 3-2, 5-1, and an end sub-frame 140 is in a first position, as shown in fig. 3-3 to 3-6, and a turned-over state in which the end main frame 100 is turned to be parallel to the bottom plate 1, the end sub-frame 140 is touchdown-supported in a second position, and the locking tongue device 122 can be in a locked state, the turning-over of the end plate 4 being achieved by turning the screw 102.

In some embodiments, as best shown in fig. 3-8, the lead screw nut 104 is further connected to a first guide member 105, and the end main frame 100 is provided with a first track groove 101 parallel to the lead screw 102, and the first guide member 105 moves in the first track groove 101. The smooth guide nut is beneficial to moving, and then the 1 st rod, the 2 nd rod and the 3 rd rod are guided to move, so that the turning plate process is smooth.

In some embodiments, the screw 102 has an operating joint 103 provided at the top end of the end main frame 100, as best shown in fig. 3-5, by rotating the operating joint 103, the screw 102 can be rotated. This facilitates the operation of the screw. The corresponding guide may be a roller, which facilitates the stability of the movement. In the illustration, for better stress, the members such as the rods and the grooves are symmetrically provided with two groups.

The locking tongue arrangement 122 may take any configuration that accomplishes the aforementioned functions. In some embodiments, as shown in the enlarged views of fig. 3-8, locking tongue arrangement 122 includes a socket 1220, a tongue 1221 and a compression spring 1222, the socket 1220 being open on lever 1 110, the tongue 1221 and the compression spring 1222 being disposed on lever 2 120, the compression spring 1222 being capable of pressing the tongue 1221 into the socket 1220 to place locking tongue arrangement 122 in a locked state, as shown in the portion indicated by B in the figures; in the unlocked state, the locking tongue 1221 is disengaged from the socket 1220, as shown in the section denoted by a. This construction is very flexible and allows the locking bolt 1221 to be manually pulled out of the socket 1220 when unlocking is desired. In the state of fig. 3-7, the locking tongue device 122 is in an unlocked state denoted a, and in the state shown in fig. 3-4 to 3-6, the locking tongue device 122 is in a locked state denoted B.

The connection of the end main frame 100 and the end sub frame 140 may take various structures. As best shown in fig. 3-3, the top end of the end main frame 100 is provided with a mounting slot 116, the end sub-frame 140 is inserted into the mounting slot 116 and is slidable relative to the mounting slot 116 from a first position to a second position, and a frame lock 160 is provided on the end main frame 100 for locking the end sub-frame 140 relative to the end main frame 100; alternatively, the end subframe 140 is hinged to the end main frame 100 so as to be capable of being flipped from a first position to a second position.

The frame lock 160 may take any configuration that can perform the aforementioned functions. In some embodiments, for example, as shown in fig. 3-3, 3-4, the frame lock 160 includes a screw 1600 rotatably mounted on the end main frame 100, the end sub-frame 140 having notches 1602 on end faces at both ends, the free end of the screw 1600 passing through the notches 1602 at one end of the end sub-frame 140, and a frame lock nut 1601 threaded onto the screw 1600 outside the notches 1602. Thus, the locking of the sub-frame 140 can be achieved with a simple structure. In fig. 3-2, 3-3, the end subframe 140 is in the first position, the free end of the screw 1600 passes through the notch 1602 at the first end (locking end in the collapsed state) of the end subframe 140, and the frame lock nut 1601 is threaded onto the screw 1600 outside of the notch 1602, thus effecting locking. To move the end subframe 140 to the second position, the frame lock 160, and in particular the frame lock nut 1601, needs to be unlocked, at which point the end subframe 140 can slide along the mounting slot 116. The end sub-frame 140 is slid down to the first end (original locking end) to touch the ground, the screw 1600 is rotated so that its free end passes through the notch 1602 of the second end (locking end in the flipped state) of the end sub-frame 140, and the frame lock nut 1601 is screwed onto the screw 1600 outside the notch 1602, thus achieving the re-locking, as shown in fig. 3-4. When it is desired to move the end subframe 140 back to the first position, the frame lock 160 is unlocked, the end subframe 140 is slid upward, and the screw 1600 is rotated to pass its free end through the notch 1602 at the first end of the end subframe 140 and secured with the frame lock nut 1601.

The following describes the method of turning the end plate rack 10. The end panel frame 10 enables the end panel and the complementary panel assembly (if any) at each end to be turned over as a whole and to serve as a support for the deck and floor after deployment.

The step of turning the end plate 4 and the patch panel assembly (if any) from perpendicular to the base plate (as shown in figures 3-2) to be coplanar with the base plate (as shown in figures 3-6) comprises: the end main frame 100 is folded and turned from being perpendicular to the bottom plate 1 to be parallel to the bottom plate 1, as shown in fig. 3-3, at this time, the 1 st rod 110 and the 2 nd rod 120 are relatively in line, and the locking tongue device 122 is in a locking state to lock the 1 st rod 110 and the 2 nd rod 120 into a straight rod, so that the 1 st rod 110, the 2 nd rod 120, the 3 rd rod 130, and a part between the first end of the 3 rd rod 130 and the first end of the 1 st rod 110 form a triangle;

moving the end subframe 140 from the first position to the second position to contact the ground as a support column, which is shown in fig. 3-4;

turning the lead screw 102, the lead screw nut 104 moves, the length of the portion between the first end of the 3 rd rod 130 and the first end of the 1 st rod 110 changes, causing the 3 rd rod 130 to rotate, driving the second guide 150 to move along the second track groove 152, achieving the overall turning of the end plate 4 and its two sides' patch panel assemblies 5, which is shown in fig. 3-5, until the end plate 4 is coplanar with the bottom plate 1, at which point the end main frame 100 acts as a supporting cross-post to support the end plate 4 and the patch panel assemblies (if any), which is shown in fig. 3-6.

The deck can be turned back perpendicular to the floor 1 using the reverse of the above procedure. When the end plate frame 10 is folded, the locking tongue device 122 can be placed in an unlocked state, the 1 st bar 110, the 2 nd bar 120, the 3 rd bar 130, and the portion between the first end of the 3 rd bar 130 and the first end of the 1 st bar 110 form a quadrangle, and the end main frame 100 can be folded to be perpendicular to the bottom plate 1 without rotating the screw 102. Fig. 3-7 illustrate this state. In fig. 3-7, end panel 4 has been folded back perpendicular to base panel 1 and end subframe 140 is moved from the second position back to the first position, and end main frame 100 may be manually flipped back perpendicular to base panel 1 in the direction of the arrow.

Moving the end subframe 140 to the second position includes: the frame lock 160 provided on the end main frame 100 for locking the end sub-frame 140 relative to the end main frame 100 is unlocked, and the end sub-frame 140 is slid within the mounting groove 116 until its original locked end touches the ground, as can be seen in fig. 3-3 and 3-4.

The end plate frame 10 thus far achieves the integral overturning of the end plates at each end and the patch plate assemblies at the two sides of the end plates, and serves as a support for the deck plate and the ground after being unfolded. Therefore, through the structure, the turnover device can save labor, and can be used as the support of the end plate and the patch assemblies on the two sides of the end plate and the ground after the patch assemblies on the two sides of the end plate are turned over. In the overturning process, the end plate and the plate supplementing assembly are always connected with the end plate frame, so that the overturning moment direction changing problem is solved, and the cabin plate is ensured to run safely and stably.

With such a terminal plate frame 10, when the terminal main frame 100 is folded and turned from being perpendicular to the bottom plate 1 to being parallel to the bottom plate 1 in the above-mentioned stage shelter form being converted from a shelter form placed on a transport vehicle to a planar stage form, the locking tongue device 122 is in a locked state, and the step of integrally turning the terminal plate 4 and the patch assemblies 5 on both sides thereof includes: turning the lead screw 102, the lead screw nut 104 moves, and the length of the portion between the first end of the 3 rd rod 130 and the first end of the 1 st rod 110 changes, causing the 3 rd rod 130 to rotate, driving the second guide 150 to move along the second rail groove 152, achieving the overall turning of the end plate 4 and the patch assemblies 5 on both sides thereof, which is shown in fig. 3-5, until the end plate 4 is coplanar with the bottom plate 1, at which time the end main frame 100 acts as a supporting cross-post to support the end plate 4, which is shown in fig. 3-6. When the stage shelter is changed from the flat stage to the shelter form placed on the transport vehicle, the locking tongue device 122 is put in the unlocked state when the stage shelter is folded, the 1 st rod 110, the 2 nd rod 120, the 3 rd rod 130, and the part between the first end of the 3 rd rod 130 and the first end of the 1 st rod 110 form a quadrangle, and the end main frame 100 can be folded to be perpendicular to the bottom plate 1 without rotating the screw 102. It will of course be appreciated that the end panel frame 10 is used to effect the inversion of the end panels at each end when the deck boards do not include a complementary panel assembly, and that the description above of the removal of the complementary panel assembly is still applicable.
