Description
Technical Field
[0001] The utility model relates to the technical field of fiberboards, in particular to a fiberboard stacking rack. Background Art
[0002] Cellulose board, usually referred to as fiberboard or density board, is a common man-made board material. It is made by interweaving wood cellulose fibers or other plant fibers, and using the adhesive properties of these fibers themselves, or adding adhesives or other additives, and pressing them under a certain temperature and pressure.
[0003] At present, some production plants store fiberboards on pallets. Due to the poor adaptability of pallets, the existing pallet specifications may not be able to flexibly adapt to fiberboards of different sizes. In addition, the pallet structure is simple and does not have a protective structure. Unreasonable stacking methods may cause the center of gravity of the fiberboard to shift, increasing the risk of unstable stacking and even leading to collapse accidents in severe cases. Summary of the invention
[0004] The utility model aims to provide a fiberboard stacking rack in view of the problems existing in the prior art.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A fiberboard stacking rack, characterized in that it comprises:
[0007] A connecting plate and a butt joint plate arranged opposite to each other;
[0008] A protective structure provided on the top of the connecting plate and the butt plate;
[0009] An adjustment component is horizontally arranged between the connecting plate and the docking plate, and the adjustment component includes two connecting frames and two docking frames, wherein one connecting frame is arranged at the front end of the connecting plate, and the other connecting frame is arranged at the rear end of the docking plate, and the two connecting frames are arranged in parallel, and the two docking frames are respectively arranged relative to the two connecting frames and movably connected with the two docking frames, and the connecting frames and the tops of the docking frames are respectively evenly opened with a plurality of first threaded holes and second threaded holes, wherein two opposite first threaded holes and the second threaded holes are threadedly connected with hand screws.
[0010] Due to the movable connection between the connecting frame and the docking frame, the size of the stacking rack can be adjusted to increase its adaptability, and it can also flexibly adapt to fiberboards of different sizes; the protective structure set on the top of the connecting plate and the docking plate can prevent the center of gravity of the fiberboard from shifting and reduce the risk of unstable stacking.
[0011] In some embodiments, the protective structure includes a side frame welded and fixed to the tops of the connecting plate and the docking plate, and a column welded between the middle of the side frame and the tops of the connecting plate and the docking plate. The side frame has a "冂"-shaped structure.
[0012] Since the side frame is arranged in a "冂"-shaped structure, there are two welding points between the side frame and the connecting plate as well as the docking plate. With the cooperating column, the connection points with the connecting plate and the docking plate are further increased. The setting of multiple connection points increases the structural stability.
[0013] In some embodiments, both the connection frame and the docking frame are integral structures, and the connection frame and the docking frame are fixedly connected to the connecting plate and the docking plate through multiple bolts.
[0014] By using multiple bolt connection components, the load can be effectively dispersed, avoiding excessive stress on a single connection point, reducing fatigue damage and the risk of potential structural failure.
[0015] In some embodiments, the front cross-section of the connection frame and the docking frame is rectangular, and the rear cross-section of the connection frame and the docking frame is a right trapezoid.
[0016] Due to having a right angle, the right trapezoid has better stability because the right angle provides a natural support point.
[0017] In some embodiments, multiple first rubber pads are adhesively bonded to the top of the connection frame. The cross-section of the first rubber pad is a right trapezoid. The first rubber pads are evenly distributed at the top end of the connection frame and are arranged staggeredly with the first threaded holes.
[0018] In this embodiment, the first rubber pads do not block the first threaded holes, facilitating the installation of hand-tightened screws.
[0019] The special shape of the trapezoidal structure can provide better stability. Its wider bottom edge can effectively disperse the load transmitted from the top, reducing the pressure per unit area.
[0020] In some embodiments, multiple hidden grooves are formed at the bottom of the connecting plate. An auxiliary wheel is installed inside the hidden grooves through a wheel axle, and the auxiliary wheel extends to the bottom of the connecting plate.
[0021] Since the auxiliary wheels are provided at the bottom of the connecting plate, the connecting plate is relatively simple and convenient to move during the adjustment process and moves more smoothly.
[0022] In some embodiments, a second rubber pad is fixedly connected by gluing at a position near the side frame at the top of the docking frame. The top end of the second rubber pad is on the same horizontal line as the top end of the first rubber pad.
[0023] The second rubber cushion block cooperates with the first rubber cushion block, which can support the four corners of the placed fiber board at the same time. The four-corner support can effectively limit the lateral and longitudinal displacement of the fiber board, and at the same time prevent the fiber board from bending and deforming, making the overall stability of the stacking rack stronger.
[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0025] 1. Since the docking frame is movably sleeved between the connecting frame, the docking frame can move towards the connecting frame and be inserted into it. During this process, the distance between the connecting plate and the docking plate continuously decreases. At the same time, moving the docking frame relative to the connecting frame can increase the distance between the connecting plate and the docking plate. By cooperating in this way, the size of the stacking rack can be adjusted to increase its adaptability, and it can also flexibly adapt to fiber boards of different sizes.
[0026] 2. Since the side frame is arranged in a "冂" - shaped structure, there are two welding points between the side frame and the connecting plate and the docking plate. With the cooperation of the arranged columns, the connection points with the connecting plate and the docking plate are further increased. The setting of multiple connection points increases the structural stability. Especially when resisting lateral forces, it can effectively reduce the swing and deformation of the structure, maintain the stable state of the structure, prevent the center of gravity of the fiber board from shifting, and reduce the risk of unstable stacking.
[0027] 3. By using multiple bolt connection components, the load can be effectively dispersed, avoiding excessive stress on a single connection point, reducing the risk of fatigue damage and potential structural failure. The use of bolts also facilitates inspection and maintenance. If a certain part needs to be repaired or replaced, individual screws can be easily disassembled and reinstalled without large - scale structural changes. Description of the Drawings

[0033] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0034] As Figure 1-3 shown, the present utility model provides a stacking rack for fiber boards, which includes:
[0035] Connecting plates 1 and docking plates 2 arranged oppositely;
[0036] A protective structure provided at the tops of the connecting plates 1 and the docking plates 2;
[0037] An adjusting assembly horizontally arranged between the connecting plates 1 and the docking plates 2. The adjusting assembly includes two connecting frames 3 and two docking frames 4. One of the connecting frames 3 is arranged at the front end of the connecting plate 1, and the other connecting frame 3 is arranged at the rear end of the docking plate 2. The two connecting frames 3 are arranged in parallel. The two docking frames 4 are respectively arranged opposite to the two connecting frames 3 and are movably sleeved between the two docking frames 4. A plurality of first threaded holes 31 and second threaded holes 41 are respectively and evenly formed at the tops of the connecting frame 3 and the docking frame 4. A hand-tightening screw 32 is threadedly connected at two opposite first threaded holes 31 and second threaded holes 41.
[0038] In this embodiment, one hand-tightening screw 32 is provided. In other embodiments, the hand-tightening screw 32 can be provided with two, three or more according to the connection length between the connecting frame 3 and the docking frame 4, which can further increase the connection strength between the connecting frame 3 and the docking frame 4.
[0039] Since the connecting frame 3 and the docking frame 4 are movably sleeved with each other, the docking frame 4 can move towards the connecting frame 3 and be inserted into its interior. During this process, the distance between the connecting plate 1 and the docking plate 2 continuously decreases. At the same time, moving the docking frame 4 relative to the connecting frame 3 can increase the distance between the connecting plate 1 and the docking plate 2. By cooperating with each other, the size of the stacking rack can be adjusted, and its adaptability can be increased. For fiber boards of different sizes, it can also be flexibly adapted.
[0040] The protective structure provided at the tops of the connecting plates 1 and the docking plates 2 can prevent the center of gravity of the fiber board from shifting and reduce the risk of unstable stacking.
[0041] In some embodiments, the protective structure includes a side frame 6 welded and fixed to the tops of the connecting plates 1 and the docking plates 2, and a column 61 welded between the middle of the side frame 6 and the tops of the connecting plates 1 and the docking plates 2. The side frame 6 has a "冂"-shaped structure.
[0042] Since the side frame 6 is arranged in a "冂" - shaped structure, there are two welding points between the side frame 6, the connecting plate 1 and the docking plate 2. With the cooperating upright column 61, the connection points between the protective structure and the connecting plate 1 and the docking plate 2 are further increased. The setting of multiple connection points increases the structural stability. Especially when resisting lateral forces, it can effectively reduce the swing and deformation of the structure, maintain the stable state of the structure, prevent the center of gravity of the fiberboard from shifting, and reduce the risk of unstable stacking.
[0043] In some embodiments, both the connecting frame 3 and the docking frame 4 are integral structures, and the connecting frame 3 and the docking frame 4 are fixedly connected to the connecting plate 1 and the docking plate 2 through a plurality of bolts.
[0044] By using a plurality of bolt - connected components, the load can be effectively dispersed, avoiding excessive stress on a single connection point, reducing the risk of fatigue damage and potential structural failure. The use of bolts also facilitates inspection and maintenance. If a certain part needs to be repaired or replaced, individual screws can be easily disassembled and reinstalled without large - scale structural changes.
[0045] In some embodiments, the front - end cross - section of the connecting frame 3 and the docking frame 4 is rectangular, and the rear - end cross - section of the connecting frame 3 and the docking frame 4 is a right - angled trapezoid.
[0046] In this embodiment, the rear - end cross - section of the connecting frame 3 and the docking frame 4 is a right - angled trapezoid. One right - angled side of the right - angled trapezoid faces upward, the other right - angled side is connected to the connecting plate 1 or the docking plate 2, and the hypotenuse faces downward.
[0047] Due to having a right - angle, the right - angled trapezoid has better stability because the right - angle provides a natural support point. In this embodiment, the lower base of the right - angled trapezoid structure is wider, and a wider base can provide a larger support area, making the structure have better stability.
[0048] In some embodiments, a plurality of first rubber pads 33 are adhesively bonded to the top of the connecting frame 3. The cross - section of the first rubber pads 33 is a right - angled trapezoid. The first rubber pads 33 are evenly distributed at the top of the connecting frame 3 and are arranged staggeredly with the first threaded holes 31.
[0049] In this embodiment, the first rubber pads 33 do not block the first threaded holes 31, which is convenient for installing the hand - tightened screws 32. At the same time, the top end of the hand - tightened screws 32 is lower than the top end of the first rubber pads 33. During the placement of the fiberboard, its bottom end surface does not contact the surface of the hand - tightened screws 32, avoiding scratching.
[0050] The special shape of the trapezoidal structure can provide better stability. Its wider bottom edge can effectively disperse the load transmitted from the top and reduce the pressure per unit area. Compared with rectangular or other shaped support structures, the trapezoidal structure can use less material while ensuring the same stability, thereby reducing costs.
[0051] In some embodiments, a plurality of dark grooves are formed at the bottom of the connecting plate 1 , and auxiliary wheels 5 are installed inside the dark grooves through axles 51 , and the auxiliary wheels 5 extend to the bottom of the connecting plate 1 .
[0052] When adjusting the stacking rack, the position of the connecting plate 1 can be adjusted by moving it relative to the docking plate 2. Since the bottom of the connecting plate 1 is provided with auxiliary wheels 5, the connecting plate 1 is easy and convenient to move, and moves more smoothly.
[0053] In some embodiments, a second rubber pad 42 is glued and fixedly connected to the top of the docking frame 4 near the side frame 6 , and the top of the second rubber pad 42 is located on the same horizontal line as the top of the first rubber pad 33 .
[0054] In this embodiment, the second rubber pad 42 is trapezoidal in front view. In other embodiments, the second rubber pad 42 may also be rectangular or other shapes with a horizontal top end surface.
[0055] The provision of the second rubber pad 42 enables the top of the connecting frame 3 to have a support point. Since the top of the second rubber pad 42 and the top of the first rubber pad 33 are located on the same horizontal line, the second rubber pad 42 cooperates with the first rubber pad 33 to simultaneously support the four corners of the placed fiberboard. The four-corner support can effectively limit the lateral and longitudinal displacement of the fiberboard to prevent it from offset, and at the same time prevent the fiberboard from bending and deformation, and the overall stability of the stacking rack is stronger.
[0056] The operation steps of this specific implementation method are:
[0057] First, loosen and remove the hand screws 32. Then, according to the size and width of the fiberboard to be placed, push the connecting plate 1 toward the docking plate 2 or pull the connecting plate 1 in the opposite direction. Adjust the distance between the connecting plate 1 and the docking plate 2 to match the size of the fiberboard to be placed. Next, slightly adjust the positions of the connecting frame 3 and the docking frame 4 so that the positions of some of the first threaded holes 31 and the second threaded holes 41 correspond. Then, install the hand screws 32 at any corresponding first threaded hole 31 and second threaded hole 41.
