Description

Technical Field

[0001] This invention relates to the field of foldable modular cabins and folding methods, specifically a foldable modular cabin and folding method. Background Technology

[0002] In various situations, modular shelters have demonstrated their versatility and adaptability. Due to their portability, customization, and time and cost savings, modular shelters are widely used for various purposes, such as on-site construction, emergency rescue, and temporary events. With continuous development and innovation, modular shelters will undoubtedly play an even more important role in different situations in the future.

[0003] The existing equipment involves workers or lifting devices lifting multiple sets of modular cabin panels, assembling them, and then fixing the round holes in the multiple sets of modular cabin panels with bolts to install the modular cabin.

[0004] During the installation of the folding modular cabin, workers need to push the folding modular cabin panels for a long time to align the round holes in the panels with the bolts. However, this assembly takes a lot of time, and workers also need to push the folding modular cabin panels for a long time to prevent the round holes in the folding modular cabin panels from becoming misaligned. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that workers need to push the folding modular unit panels for a long time to align the round holes in the panels with bolts, but this assembly takes a lot of time and workers also need to push the folding modular unit panels for a long time to prevent the round holes in the panels from becoming misaligned. This invention provides a method for folding modular units that is easy to fold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable modular container and a folding method thereof, wherein lifting the first modular container panel upwards causes the first fixed block to move upwards, and the first fixed block causes the first cylinder, the second cylinder, and the second fixed block to move upwards, thereby causing the second modular container panel to move upwards. When the first and second modular container panels move upwards, the first and second cylinders rotate with a ratchet. When the first and second modular container panels reach their moving positions, lifting the first modular container panel upwards stops, and the first modular container panel... The plate will move downwards, causing the No. 1 fixed block, the No. 1 cylinder, and the No. 2 cylinder to move downwards to a certain position. When the No. 1 cylinder moves downwards, the No. 2 cylinder will rotate to a certain extent. When the No. 2 cylinder rotates, the end of the wedge plate in the No. 2 cylinder engages in the ratchet, causing the No. 2 cylinder to stop rotating. When the No. 2 cylinder stops rotating, the No. 1 container plate and the No. 1 cylinder will stop moving downwards. It is not necessary to lift the No. 1 container plate for a long time. After lifting the No. 1 container plate several times, the No. 1 container plate can be fully supported. It can be supported without the need for external lifting or long-term lifting of the No. 1 container plate.

[0007] As a further aspect of the present invention: when the No. 1 modular unit is fully supported, the No. 4 modular unit is pushed upwards, causing the compression column at the end of the No. 4 modular unit to be squeezed into the circular hole by the bottom of the No. 1 modular unit. The compression column squeezes the end of the fixing plate, and through the lever principle, the end of the fixing plate pushes the support angle towards the bottom of the No. 1 modular unit, so that the top of the support angle contacts the bottom of the No. 1 modular unit. The compression column being squeezed into the circular hole by the bottom of the No. 1 modular unit drives the wedge column to move to one end, causing the wedge column to squeeze the No. 1 wedge groove in the No. 1 support plate, causing the No. 1 support plate to slide outwards towards the outside of the No. 4 modular unit. When the No. 1 support plate moves, it squeezes the No. 3 wedge groove in the No. 2 support plate through the No. 2 wedge groove, causing the No. 2 support plate to slide outwards towards the outside of the No. 4 modular unit. Through the support angle, the No. 1 support plate and the No. 2 support plate move outwards towards the outside of the No. 4 modular unit, thereby better fixing the No. 4 modular unit to the bottom of the No. 1 modular unit and preventing the No. 4 modular unit from slipping.

[0008] As a further embodiment of the present invention: Two second-stage modular units are provided on both sides of the bottom of the first modular unit. A first-stage fixing block is provided at both the bottom and top of the second-stage modular unit. A first-stage cylinder is fixed to the bottom of the first-stage fixing block. A ratchet is fixed inside the first-stage cylinder. The end of the ratchet is rotatably connected to the second-stage cylinder. Four sets of wedge plates are provided inside the second-stage cylinder. A fixing rod drives two sets of wedge plates to rotate clockwise, and the other two sets to rotate counterclockwise, adjusting the contact position between the wedge plates and the ratchet. A fixing rod is fixed to the head end of each wedge plate. The end of the arc-shaped plate leaves the interior of the second arc-shaped groove. Rotating the circular plate causes the toothed ring groove to rotate, which in turn drives the four sets of gears to rotate. The gears then drive the fixing rod to rotate.

[0009] As a further embodiment of the present invention: a gear is fixed to the end of the fixing rod; a first spring is provided on the outer side of the wedge plate; a first arc groove is provided at one end of the second cylinder; a second arc groove is provided on the inner wall of the first arc groove; an arc plate is provided inside the first arc groove; lifting the first modular unit panel allows it to be fully supported without the need for external lifting or prolonged lifting; pressing the pressing block compresses the arc plate, causing it to rotate using a lever principle; a second spring is provided on the inner side of the arc plate; a circular plate is provided at one end of the first arc groove; a toothed ring groove is provided at one end of the circular plate; a first groove is provided on both sides of the circular plate; a pressing block is slidably connected inside the first groove; and the end of the arc plate penetrates the interior of the first groove and contacts the end of the pressing block.

[0010] As a further embodiment of the present invention: the wedge plates are evenly arranged on the outside of the ratchet, the gear passes through one end of the second cylinder, and the gear ring groove meshes with the gear.

[0011] As a further embodiment of the present invention: one end of the arc-shaped plate is rotatably connected to a second rotating shaft. When the pressing block is released, the end of the arc-shaped plate will be engaged inside the second arc-shaped groove on the other side. When the position of the wedge plate in contact with the ratchet is adjusted, one side of the second container plate is pushed. The second rotating shaft is rotatably connected to the inner wall of the first arc-shaped groove.

[0012] As a further embodiment of the present invention: a second fixing block is fixed to the bottom of the second cylinder, a third container plate is provided at the bottom of the second container plate, the first container plate drives the first fixing block to move upward, the first fixing block drives the first cylinder, the second cylinder, and the second fixing block to move upward, thereby driving the second container plate to move upward, and the top two ends of the third container plate are rotatably connected to the fourth container plate.

[0013] As a further embodiment of the present invention: the end of the fourth modular unit is rotatably connected to a first rotating shaft, and round holes are provided on both sides of the front end of the fourth modular unit.

[0014] As a further embodiment of the present invention: a groove is provided at the top of the circular hole, a support angle is slidably connected inside the groove, a fixing plate is provided inside the circular hole, the extrusion column at the end of the fourth modular unit is squeezed into the circular hole by the bottom of the first modular unit, the extrusion column squeezes the end of the fixing plate, and the end of the fixing plate pushes the support angle toward the bottom of the first modular unit through the lever principle, and the middle of the fixing plate is rotatably connected to the third rotating shaft.

[0015] As a further embodiment of the present invention: the two ends of the No. 3 rotating shaft are rotatably connected to the inner wall of the circular hole, and a No. 3 spring is provided at one end inside the circular hole. A compression column is fixed at the end of the No. 3 spring, and the top of the support angle contacts the bottom of the No. 1 container panel to fix it, so that the No. 4 container panel can better contact the bottom of the No. 1 container panel and prevent the No. 4 container panel from slipping. The support angle is slidably connected inside the slide groove.

[0016] As a further embodiment of the present invention: a wedge-shaped column is fixed at the upward position of the end of the extrusion column; the second groove is disposed on both sides of the outer side of the fourth container panel; a first support plate is slidably connected inside the second groove; a first wedge-shaped groove is disposed on one side of one end of the first support plate; the end of the wedge-shaped column is in contact with the inside of the first wedge-shaped groove; a second wedge-shaped groove is disposed in the middle of the first support plate; a second support plate is disposed inside the second wedge-shaped groove; a third wedge-shaped groove is disposed on one side of the second support plate; and the third wedge-shaped groove is in contact with the second wedge-shaped groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By lifting the No. 1 modular unit upwards, the No. 1 modular unit moves upwards. When the No. 2 cylinder rotates, the end of the wedge plate in the No. 2 cylinder engages with the ratchet, causing the No. 2 cylinder to stop rotating. When the No. 2 cylinder stops rotating, the No. 1 modular unit and the No. 1 cylinder will stop moving downwards. It is not necessary to lift the No. 1 modular unit for a long time. After lifting the No. 1 modular unit multiple times, the No. 1 modular unit is fully supported. It can be supported without the need for external lifting or long-term lifting of the No. 1 modular unit.

[0019] 2. By pressing the arc-shaped plate with the set pressing block, the arc-shaped plate rotates according to the lever principle, causing the end of the arc-shaped plate to leave the interior of the second arc-shaped groove. Rotating the circular plate causes the two sets of wedge plates to rotate clockwise, while the other two sets rotate counterclockwise. Adjust the position of the wedge plates in contact with the ratchet, release the pressing block, and the end of the arc-shaped plate will be locked inside the second arc-shaped groove on the other side. When the position of the wedge plates in contact with the ratchet is adjusted, push one side of the second modular container panel, causing the second modular container panel to fall to one side and fold.

[0020] 3. By pressing the end of the fixed plate with the set extrusion column, the end of the fixed plate pushes the support angle towards the bottom of the No. 1 container panel through the lever principle, so that the top of the support angle contacts the bottom of the No. 1 container panel. The extrusion column is pressed into the round hole by the bottom of the No. 1 container panel, which drives the wedge column to move to one end, so that the wedge column presses the No. 1 wedge groove in the No. 1 support plate, so that the No. 1 support plate slides to the outside of the No. 4 container panel, thereby better fixing the No. 4 container panel to the bottom of the No. 1 container panel.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 , 2In embodiments of the present invention, a foldable modular container and a folding method are provided, including a first modular container panel 1. Second modular container panels 101 are provided on both sides of the bottom of the first modular container panel 1. A first fixing block 201 is provided at both the bottom and top of the second modular container panel 101. A first cylinder 202 is fixed to the bottom of the first fixing block 201. A ratchet 3 is fixed inside the first cylinder 202. The end of the ratchet 3 is rotatably connected to a second cylinder 204. Four sets of wedge plates 301 are provided inside the second cylinder 204. A fixing rod 303 drives two sets of wedge plates 301 to rotate clockwise, while the other two sets... Rotate counterclockwise to adjust the contact position between the wedge plate 301 and the ratchet 3. The first end of the wedge plate 301 is fixed with a fixing rod 303. The end of the arc plate 402 leaves the interior of the second arc groove 401. Rotate the circular plate 5. The circular plate 5 drives the gear ring groove 502 to rotate. The gear ring groove 502 drives the four sets of gears 304 to rotate. The gears 304 drive the fixing rod 303 to rotate. The end of the fixing rod 303 is fixed with a gear 304. A first spring 302 is provided on the outside of the wedge plate 301. A first arc groove 4 is provided at one end of the second cylinder 204. The inner wall of the first arc groove 4 is provided with the second arc groove 401.

[0031] The first arc-shaped groove 4 has an arc-shaped plate 402 inside. Lifting the first modular unit 1 fully supports it without the need for external lifting or prolonged lifting. Pressing the pressing block 503 compresses the arc-shaped plate 402, causing it to rotate using a lever principle. A second spring 403 is installed inside the arc-shaped plate 402. A circular plate 5 is installed at one end of the first arc-shaped groove 4, and a toothed ring groove 502 is installed at one end of the circular plate 5. First grooves 501 are installed on both sides of the circular plate 5, and pressing blocks 503 are slidably connected inside the first groove 501. The end of the arc plate 402 passes through the interior of the first groove 501 and contacts the end of the pressing block 503. The wedge plate 301 is evenly arranged on the outside of the ratchet 3. The gear 304 passes through one end of the second cylinder 204. The gear ring groove 502 meshes with the gear 304. One end of the arc plate 402 is rotatably connected to the second rotating shaft 404. When the pressing block 503 is released, the end of the arc plate 402 will be locked in the interior of the second arc groove 401 on the other side. When the position of the wedge plate 301 in contact with the ratchet 3 is adjusted, one side of the second container plate 101 is pushed. The second rotating shaft 404 is rotatably connected to the inner wall of the first arc groove 4.

[0032] In this embodiment: After repeatedly lifting the No. 1 modular unit panel 1, it is fully supported without the need for external lifting or prolonged lifting. Pressing the pressing block 503 compresses the arc-shaped plate 402, causing it to rotate using a lever principle. This causes the end of the arc-shaped plate 402 to leave the interior of the No. 2 arc-shaped groove 401. Rotating the circular plate 5 then drives the gear ring groove 502 to rotate, which in turn drives the four sets of gears 304 to rotate. When the gear 304 moves, the fixed rod 303 rotates, and the fixed rod 303 drives the two sets of wedge plates 301 to rotate clockwise, while the other two sets rotate counterclockwise. Adjust the position of the wedge plate 301 in contact with the ratchet 3, release the pressing block 503, and the end of the arc plate 402 will be engaged in the interior of the second arc groove 401 on the other side. When the position of the wedge plate 301 in contact with the ratchet 3 is adjusted, push one side of the second container panel 101, causing the second container panel 101 to fall to one side and fold.

[0033] Please refer to this carefully. Figure 4 , 5 The bottom of the second cylinder 204 is fixed with the second fixing block 203. The bottom of the second container plate 101 is provided with the third container plate 102. The first container plate 1 drives the first fixing block 201 to move upward. The first fixing block 201 drives the first cylinder 202, the second cylinder 204, and the second fixing block 203 to move upward, thereby driving the second container plate 101 to move upward. The top two ends of the third container plate 102 are rotatably connected to the fourth container plate 103. The end of the fourth container plate 103 is rotatably connected to the first rotating shaft 104. The two sides of the head end of the fourth container plate 103 are provided with round holes 601. The top of the round holes 601 is provided with a sliding groove 6. The inside of the sliding groove 6 is slidably connected with a support angle 606.

[0034] A fixing plate 603 is installed inside the circular hole 601. The extrusion column 602 at the end of the fourth modular unit 103 is pressed into the circular hole 601 by the bottom of the first modular unit 1. The extrusion column 602 presses against the end of the fixing plate 603. Through the lever principle, the end of the fixing plate 603 pushes the support angle 606 towards the bottom of the first modular unit 1. A third rotating shaft 604 is rotatably connected to the middle of the fixing plate 603. Both ends of the third rotating shaft 604 are rotatably connected to the inner wall of the circular hole 601. A third spring 605 is installed at one end inside the circular hole 601. The extrusion column 602 is fixed to the end of the third spring 605. The top of the support angle 606 contacts the bottom of the first modular unit 1, thereby fixing it and making the fourth modular unit 103 better aligned with the first modular unit 1. The bottom of panel 103 of the fourth modular container is in contact with the bottom to prevent it from slipping. A support angle 606 is slidably connected inside the chute 6. A wedge-shaped column 607 is fixed at the upward position of the end of the compression column 602. The second groove 608 is set on both sides of the outer side of the fourth modular container panel 103. A support plate 609 is slidably connected inside the second groove 608. A wedge-shaped groove 610 is set on one side of one end of the support plate 609. The end of the wedge-shaped column 607 is in contact with the inside of the first wedge-shaped groove 610. A second wedge-shaped groove 611 is set in the middle of the support plate 609. A support plate 612 is set inside the second wedge-shaped groove 611. A third wedge-shaped groove 613 is set on one side of the support plate 612. The third wedge-shaped groove 613 is in contact with the second wedge-shaped groove 611.

[0035] In this embodiment: The first modular unit 1 moves the first fixed block 201 upwards. The first fixed block 201 moves the first cylinder 202, the second cylinder 204, and the second fixed block 203 upwards, thereby moving the second modular unit 101 upwards. When the first modular unit 1 and the second modular unit 101 move upwards, the first cylinder 202 and the second cylinder 204 rotate with the ratchet 3. When the first modular unit 1 and the second modular unit 101 reach their moving positions, the upward movement of the first modular unit 1 stops. The downward movement of module 1 will cause the first fixed block 201, the first cylinder 202, and the second cylinder 204 to move downwards to a certain position. As the first cylinder 202 moves downwards, the second cylinder 204 will rotate slightly. When the second cylinder 204 rotates, the end of the wedge plate 301 inside the second cylinder 204 engages with the ratchet 3, causing the second cylinder 204 to stop rotating. When the second cylinder 204 stops rotating, module 1 and the first cylinder 202 will stop moving downwards. Therefore, it is not necessary to lift module 1 for an extended period before pushing module 1 upwards. 03. The compression column 602 at the end of the fourth modular unit 103 is pressed into the circular hole 601 by the bottom of the first modular unit 1. The compression column 602 presses against the end of the fixing plate 603. Through the lever principle, the end of the fixing plate 603 pushes the support angle 606 towards the bottom of the first modular unit 1, so that the top of the support angle 606 contacts the bottom of the first modular unit 1. The compression column 602 being pressed into the circular hole 601 by the bottom of the first modular unit 1 drives the wedge column 607 to move to one end, so that the wedge column 607 presses against the first support plate 609. The wedge groove 610 allows the first support plate 609 to slide outwards toward the fourth container panel 103. When the first support plate 609 moves, it presses the third wedge groove 613 in the second support plate 612 through the second wedge groove 611, causing the second support plate 612 to slide outwards toward the fourth container panel 103. Through the support angle 606, the first support plate 609 and the second support plate 612 move outwards toward the fourth container panel 103, thereby better fixing the fourth container panel 103 to the bottom of the first container panel 1 and preventing the fourth container panel 103 from slipping.

[0036] Working principle: The first modular unit 1 is lifted upwards, causing the first fixed block 201 to move upwards. The first fixed block 201 then moves the first cylinder 202, the second cylinder 204, and the second fixed block 203 upwards, thereby causing the second modular unit 101 to move upwards. As the first and second modular units 101 move upwards, the first and second cylinders 202 and 204 rotate with the ratchet 3. When the first and second modular units 101 reach their moving positions and the lifting of the first modular unit 1 stops, the first modular unit 1 will move downwards, causing the first fixed block 203 to move downwards. 1. Cylinder 1 202 and Cylinder 204 move downwards to a certain position. When Cylinder 1 202 moves downwards, Cylinder 204 will rotate to a certain extent. When Cylinder 204 rotates, the end of the wedge plate 301 in Cylinder 204 is engaged in the ratchet 3, causing Cylinder 204 to stop rotating. When Cylinder 204 stops rotating, Cylinder 1 and Cylinder 202 will stop moving downwards. It is not necessary to lift Cylinder 1 for a long time. After lifting Cylinder 1 multiple times, Cylinder 1 is fully supported. It can be supported without the need for external lifting or long-term lifting.

[0037] Press the pressing block 503, which squeezes the arc plate 402, causing the arc plate 402 to rotate using the lever principle. This causes the end of the arc plate 402 to leave the interior of the second arc groove 401. Rotate the circular plate 5, which drives the toothed ring groove 502 to rotate. The toothed ring groove 502 drives the four sets of gears 304 to rotate. The gears 304 drive the fixed rod 303 to rotate. The fixed rod 303 drives two sets of wedge plates 301 to rotate clockwise, while the other two sets rotate counterclockwise. Adjust the position of the wedge plate 301 in contact with the ratchet 3. Release the pressing block 503, and the end of the arc plate 402 will be engaged inside the second arc groove 401 on the other side. When the position of the wedge plate 301 in contact with the ratchet 3 is adjusted, push one side of the second container panel 101, causing the second container panel 101 to fall to one side and fold.

[0038] When the No. 1 modular unit 1 is fully erected, it pushes the No. 4 modular unit 103 upwards, causing the compression column 602 at the end of the No. 4 modular unit 103 to be squeezed into the circular hole 601 by the bottom of the No. 1 modular unit 1. The compression column 602 squeezes the end of the fixing plate 603, and through the lever principle, the end of the fixing plate 603 pushes the support angle 606 towards the bottom of the No. 1 modular unit 1, so that the top of the support angle 606 contacts the bottom of the No. 1 modular unit 1. The compression column 602 being squeezed into the circular hole 601 by the bottom of the No. 1 modular unit 1 drives the wedge column 607 to move to one end, causing the wedge column 607 to squeeze the No. 1 wedge in the No. 1 support plate 609. The groove 610 allows the first support plate 609 to slide outward toward the fourth container panel 103. When the first support plate 609 moves, it squeezes the third wedge groove 613 in the second support plate 612 through the second wedge groove 611, causing the second support plate 612 to slide outward toward the fourth container panel 103. Through the support angle 606, the first support plate 609 and the second support plate 612 move outward toward the fourth container panel 103, thereby better fixing the fourth container panel 103 to the bottom of the first container panel 1 and preventing the fourth container panel 103 from slipping. Because the extrusion column 602 is made of rubber, the extrusion column 602 has a certain degree of elasticity.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

3. The foldable modular cabin according to claim 1, characterized in that, A wedge-shaped column (607) is fixed at the upward position of the end of the extrusion column (602). The second groove (608) is set on both sides of the outer side of the fourth container panel (103). The second groove (608) is slidably connected to the first support plate (609). A wedge-shaped groove (610) is set on one side of one end of the first support plate (609). The end of the wedge-shaped column (607) is in contact with the interior of the first wedge-shaped groove (610). A second wedge-shaped groove (611) is set in the middle of the first support plate (609). A second support plate (612) is set inside the second wedge-shaped groove (611). A third wedge-shaped groove (613) is set on one side of the second support plate (612). The third wedge-shaped groove (613) is in contact with the second wedge-shaped groove (611).

4. A folding method for a foldable modular container according to any one of claims 1-3, characterized in that, The specific steps are as follows: S1: Lifting the No. 1 modular unit (1) upwards causes the No. 1 fixed block (201) to move upwards. The No. 1 fixed block (201) then causes the No. 1 cylinder (202), the No. 2 cylinder (204), and the No. 2 fixed block (203) to move upwards, thereby causing the No. 2 modular unit (101) to move upwards. When the No. 1 modular unit (1) and the No. 2 modular unit (101) move upwards, the No. 1 cylinder (202) and the No. 2 cylinder (204) rotate with the ratchet (3). When the No. 1 modular unit (1) and the No. 2 modular unit (101) move upwards to the moving position, and the lifting of the No. 1 modular unit (1) stops, the No. 1 modular unit (1) will move downwards, causing the No. 1 fixed block (202) to move downwards. 1) Cylinder 1 (202) and Cylinder 2 (204) move downwards to a certain position. When Cylinder 1 (202) moves downwards, Cylinder 2 (204) will rotate to a certain extent. When Cylinder 2 (204) rotates, the end of the wedge plate (301) in Cylinder 2 (204) is engaged in the ratchet (3), so that Cylinder 2 (204) stops rotating. When Cylinder 2 (204) stops rotating, Cylinder 1 (1) and Cylinder 1 (202) will stop moving downwards. It is not necessary to lift Cylinder 1 (1) for a long time. After lifting Cylinder 1 (1) multiple times, Cylinder 1 (1) can be fully supported. It is not necessary to lift external objects or lift Cylinder 1 (1) for a long time to complete the support. S2: When the No. 1 modular unit (1) is fully supported, the No. 4 modular unit (103) is pushed upwards, causing the compression column (602) at the end of the No. 4 modular unit (103) to be squeezed into the round hole (601) by the bottom of the No. 1 modular unit (1). The compression column (602) squeezes the end of the fixing plate (603), and through the lever principle, the end of the fixing plate (603) pushes the support angle (606) towards the bottom of the No. 1 modular unit (1), so that the top of the support angle (606) contacts the bottom of the No. 1 modular unit (1). Through the compression column (602) being squeezed into the round hole (601) by the bottom of the No. 1 modular unit (1), the wedge column (607) moves to one end, causing the wedge column (607) to move to one end. Squeeze the first wedge groove (610) in the first support plate (609) to make the first support plate (609) slide to the outside of the fourth container plate (103). When the first support plate (609) moves, it squeezes the third wedge groove (613) in the second support plate (612) through the second wedge groove (611) to make the second support plate (612) slide to the outside of the fourth container plate (103). Through the support angle (606), the first support plate (609) and the second support plate (612) move to the outside of the fourth container plate (103), so that the fourth container plate (103) is better fixed to the bottom of the first container plate (1) and prevents the fourth container plate (103) from slipping.
