Description
Technical Field
[0001] This utility model relates to the field of container panel technology, specifically to a placement rack for moving container panels. Background Technology
[0002] In recent years, with the improvement of living standards in my country and strong government support for the tourism industry, the demand for outdoor work and living has increased. More and more people are choosing mobile modular units for office and living, as well as for camping in outdoor campsites. Therefore, the demand for mobile modular units is constantly increasing, and under the influence of various factors, it is expected to continue its rapid growth for a long time to come. Among these, modular unit panels are a crucial component, and shelving plays an indispensable role in their transportation during the panel production process. The commonly used shelving is manufactured through integral welding, resulting in bulky and inconvenient shelving that is difficult to move. This leads to high shipping and relocation costs, and the limited number of panels that can be placed on the shelving results in low panel transportation efficiency. Therefore, there is an urgent need for a placement rack for mobile modular units to solve these problems. Utility Model Content
[0003] To address the technical problems of existing shelving manufacturing processes involving integral welding, resulting in bulkiness, inconvenience in movement, and low efficiency in pallet transfer due to the limited number of pallets that can be placed on the shelves, this utility model provides a pallet placement rack for movement. The rack has a simple structure, is easy to assemble and disassemble; the support components and lining structure are fixed to the movable frame for assembly, and the connections between them are reliable, resulting in low shipping and relocation costs. The rack is easy to move as a whole, has high space utilization, can load and transfer multiple pallets at once, and the pallets are not easily deformed. The limiting parts also prevent pallets from falling during transfer, effectively improving the pallet transfer efficiency.
[0004] This utility model provides a placement rack for movable boxes, including a movable frame and a support member fixedly installed at the center of the movable frame. The movable frame is fixedly provided with a liner structure located on both sides of the support member. A limiting part is fixedly provided on the liner structure. Multiple boxes to be moved are evenly placed on both sides of the movable frame and arranged symmetrically. Multiple boxes on the same side of the movable frame are placed sequentially and inclined. The bottoms of multiple boxes on the same side of the movable frame are locked with the limiting part. The tops of multiple boxes on the same side of the movable frame are in sequential contact, and the top of the innermost box is in contact with the support member.
[0005] Furthermore, the mobile frame includes a first crossbeam, a second crossbeam, a third crossbeam, a fourth crossbeam, a fifth crossbeam, a sixth crossbeam, and a reinforcing beam. The first and second crossbeams are arranged opposite each other. The third and fourth crossbeams are fixedly arranged between the two ends of the first and second crossbeams, respectively. The fifth and sixth crossbeams are fixedly arranged between the middle parts of the first and second crossbeams, respectively. The reinforcing beam is evenly fixed between the third and fifth crossbeams and between the fourth and sixth crossbeams. Universal locking wheels are provided at the bottom of both ends of the first and second crossbeams, and universal wheels are provided at the bottom of the middle part of the third and fourth crossbeams. When the universal locking wheels are locked, the mobile frame is fixed, and boxes can be loaded onto or unloaded from the mobile frame. When the universal locking wheels are opened, the mobile frame moves via the universal locking wheels and the universal wheels, thereby enabling the transfer of boxes.
[0006] Furthermore, a first plug is fixedly installed inside both ends of the first and second crossbeams. The first plug is embedded in the openings at both ends of the first and second crossbeams, preventing bumps and scratches to workers, and also serving an aesthetic purpose.
[0007] Furthermore, the support component includes two sets of support sections. Multiple fixed plates, the same number as the support sections, are evenly fixed between the fifth and sixth crossbeams. The two sets of support sections are symmetrically arranged on the multiple fixed plates. Each set of support sections includes a support crossbeam and multiple support columns. The bottoms of the multiple support columns are respectively fixed to the multiple fixed plates, and the tops of the multiple support columns are fixedly connected to the support crossbeam. The top of the innermost box panel contacts the support crossbeam. The upper part of the innermost box panel contacts the support crossbeam. Since multiple box panels on the same side are placed sequentially, the weight of all box panels on the same side is ultimately borne by the support crossbeam and the multiple support columns.
[0008] Furthermore, a supporting longitudinal beam is fixedly connected to both ends of the two supporting crossbeams, and a second plug is fixedly installed inside both ends of the two supporting crossbeams. The second plug is embedded in the openings at both ends of the supporting crossbeams, and the second plug also prevents bumps and scratches to workers, while also serving an aesthetic purpose.
[0009] Furthermore, the lining structure includes a first lining plate, a second lining plate, a third lining plate, and a fourth lining plate; the first lining plate is fixedly mounted on the first, third, and fifth crossbeams, as well as a portion of the reinforcing beam located between the third and fifth crossbeams; the second lining plate is fixedly mounted on the second, third, and fifth crossbeams, as well as a portion of the reinforcing beam located between the third and fifth crossbeams; the third lining plate is fixedly mounted on the first, fourth, and sixth crossbeams, as well as a portion of the reinforcing beam located between the fourth and sixth crossbeams; the fourth lining plate is fixedly mounted on the second, fourth, and sixth crossbeams, as well as a portion of the reinforcing beam located between the fourth and sixth crossbeams; gaps are left between the ends of the first and second lining plates, and between the ends of the third and fourth lining plates. The arrangement of the first, second, third, and fourth lining plates enhances the structural strength of the movable frame, improving its overall planar load-bearing capacity.
[0010] Furthermore, the limiting part includes multiple limiting strips, which are evenly fixedly disposed between the ends of the first, second, third, and fourth liners, the first and second liners, and the third and fourth liners by first self-drilling self-tapping screws. The bottoms of multiple panels located on the same side of the movable frame are engaged between adjacent limiting strips. In extreme cases, such as when turning or going over potholes, if the panel shakes, the adjacent limiting strips can limit the position of the lower part of the panel. The lower part of the panel can only sway slightly between the adjacent limiting strips, and after the swaying is complete, the panel remains stable between the two limiting strips and does not fall, thus preventing the panel from being bumped or scratched if it falls.
[0011] Furthermore, the limiting strip is provided with a first pin hole, and the first, second, third, and fourth liner plates are provided with second pin holes at positions corresponding to the first pin hole. The positioning pin passes through the first pin hole and into the second pin hole. The positioning pin can quickly position the limiting strip, eliminating the need for the limiting strip to be located manually. Then, the limiting strip is locked with a first self-drilling self-tapping screw, enabling the limiting strip to be installed quickly.

[0013] This utility model of a placement rack has a simple structure, low assembly difficulty, and convenient disassembly and assembly. The support components and lining plate structure are fixed on the mobile frame to achieve assembly, and the connection between them is reliable. The shipping and relocation costs are low. The placement rack is easy to move as a whole, has a high space utilization rate, and can load and transfer multiple boxes at one time. The boxes are not easily deformed when placed, and the limiting part also prevents the boxes from falling off during transfer, effectively improving the transfer efficiency of the boxes.

Detailed Implementation
[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] like Figures 1-15 As shown, a placement rack for moving boxes includes a movable frame 1 and a support member 2 fixedly disposed at the center of the movable frame 1. The movable frame 1 is fixedly provided with liner structures 3 located on both sides of the support member 2. Limiting parts 4 are fixedly provided on the liner structures 3. Multiple boxes 5 to be transferred are evenly placed on both sides of the movable frame 1 and arranged symmetrically. Multiple boxes 5 located on the same side of the movable frame 1 are placed sequentially and inclined. The inclination of multiple boxes 5 located on the same side of the movable frame 1 increases sequentially from the inside to the outside, with the outermost box 5 having the largest inclination. The lower parts of multiple boxes 5 located on the same side of the movable frame 1 are placed at the limiting parts 4. The upper parts of multiple boxes 5 located on the same side of the movable frame 1 are in sequential contact, with the upper part of the innermost box 5 in contact with the support member 2.
[0033] In this embodiment, when the placement rack is used to transfer the box plates 5, multiple box plates 5 to be moved are evenly placed on both sides of the movable frame 1 and arranged symmetrically. Multiple box plates 5 on the same side of the movable frame 1 are placed sequentially and at an angle. Specifically, the lower parts of the multiple box plates 5 on the same side of the movable frame 1 are placed on the limiting part 4, and the upper parts of the multiple box plates 5 on the same side of the movable frame 1 are in sequential contact, with the upper part of the innermost box plate 5 contacting the support member 2. It is worth noting that the box plates 5 are relatively heavy, so they generally remain stable during transfer. In extreme cases, such as when turning or going over potholes, if the box plate 5 shakes, the limiting part 4 can limit the position of the box plate 5, ensuring that the box plate 5 remains stable after shaking and does not fall.
[0034] The structure of the placement rack in this embodiment is simple, easy to assemble and disassemble. The support 2 and the liner structure 3 are fixed on the mobile frame 1 to achieve assembly and the connection between them is reliable. The shipping and relocation costs are low. The placement rack is easy to move as a whole and has a high space utilization rate. Multiple boxes 5 can be loaded and transferred at one time. The boxes 5 are not easily deformed when placed. The limiting part 4 also prevents the boxes 5 from falling off during transfer, which effectively improves the transfer efficiency of the boxes 5.
[0035] In one possible implementation, the movable frame 1 includes a first crossbeam 11, a second crossbeam 12, a third crossbeam 13, a fourth crossbeam 14, a fifth crossbeam 15, a sixth crossbeam 16, and a reinforcing beam 17. The first crossbeam 11 and the second crossbeam 12 are arranged opposite to each other. The third crossbeam 13 and the fourth crossbeam 14 are respectively fixed between the two ends of the first crossbeam 11 and the second crossbeam 12. The fifth crossbeam 15 and the sixth crossbeam 16 are respectively fixed between the middle parts of the first crossbeam 11 and the second crossbeam 12. The reinforcing beam 17 is evenly fixed between the third crossbeam 13 and the fifth crossbeam 15, and between the fourth crossbeam 14 and the sixth crossbeam 16. Universal locking wheels 18 are provided at the bottom of both ends of the first crossbeam 11 and the second crossbeam 12, and universal wheels 19 are provided at the bottom of the middle part of the third crossbeam 13 and the fourth crossbeam 14. The structures of the universal locking wheels 18 and the universal wheels 19 are existing technology and will not be described in detail here. The omnidirectional locking wheel 18 and omnidirectional wheel 19 are high load-bearing components, with the advantages of smooth steering and strong load-bearing capacity.
[0036] The first crossbeam 11, second crossbeam 12, third crossbeam 13, fourth crossbeam 14, fifth crossbeam 15, sixth crossbeam 16, and reinforcing beam 17 of the mobile frame 1 have a simple structure and are independently installed, resulting in high processing efficiency and convenient assembly and disassembly, eliminating the need for on-site drilling and welding. The mobile frame 1 uses universal locking wheels 18 and universal wheels 19, enabling lightweight wheel-driven relocation and facilitating easy movement. When the universal locking wheels 18 are locked, the mobile frame 1 is fixed in place, allowing the box panel 5 to be loaded onto or unloaded from it. Opening the universal locking wheels 18 allows the mobile frame 1 to move via the universal locking wheels 18 and universal wheels 19, thereby enabling the transfer of the box panel 5.
[0037] The placement frame includes a connecting component 7, which includes a first inner threaded nut 71, a second inner threaded nut 72, a third inner threaded nut 73, a fourth inner threaded nut 74, and a fifth inner threaded nut 75.
[0038] Furthermore, the first crossbeam 11, the second crossbeam 12, the third crossbeam 13, the fourth crossbeam 14, the fifth crossbeam 15, the sixth crossbeam 16, and the reinforcing beam 17 are all rectangular tubes, and are located on the same horizontal plane. Preferably, the first crossbeam 11 and the second crossbeam 12 are provided with first mounting holes at both ends, and the third crossbeam 13 and the fourth crossbeam 14 are provided with first inner thread nuts 71 in the openings at both ends. The first inner thread nuts 71 are M8×40×80 square tube (double hole) inner thread nuts. The first bolt passes through the first mounting hole and is fixedly connected to the first inner thread nuts 71, thus achieving a fixed connection between the first crossbeam 11, the second crossbeam 12, the third crossbeam 13, and the fourth crossbeam 14. The first crossbeam 11 and the second crossbeam 12 each have a second mounting hole in their middle. The fifth crossbeam 15 and the sixth crossbeam 16 each have a second inner threaded nut 72 in their openings at both ends. A second bolt passes through the second mounting hole and is fixedly connected to the second inner threaded nut 72, thus fixing the fifth crossbeam 15 and the sixth crossbeam 16 to the first crossbeam 11 and the second crossbeam 12. The third crossbeam 13 and the fifth crossbeam 15, as well as the fourth crossbeam 14 and the sixth crossbeam 16, each have multiple third mounting holes evenly distributed in their middle. The reinforcing beam 17 each has a third inner threaded nut 73 in its openings at both ends. A third bolt passes through the third mounting hole and is fixedly connected to the third inner threaded nut 73. The second inner threaded nut 72 and the third inner threaded nut 73 are M8×40×40 square tube inner threaded nuts.
[0039] Furthermore, both ends of the first crossbeam 11 and the second crossbeam 12 are provided with first bolt holes, and the column at the top of the universal locking wheel 18 passes through the first bolt holes and is fixedly connected to the bottom of both ends of the first crossbeam 11 and the second crossbeam 12 by the first nut.
[0040] Furthermore, the third crossbeam 13 and the fourth crossbeam 14 are each provided with a second bolt hole in the middle. The column at the top of the caster wheel 19 passes through the second bolt hole and is fixedly connected to the bottom of the middle part of the third crossbeam 13 and the fourth crossbeam 14 by the second nut.
[0041] As one possible implementation, a first plug 111 is fixedly installed in the openings at both ends of the first crossbeam 11 and the second crossbeam 12. The first plug 111 is embedded in the openings at both ends of the first crossbeam 11 and the second crossbeam 12. The first plug 111 prevents workers from being bumped or scratched, and also has an aesthetic function.
[0042] In one possible implementation, the support member 2 includes two sets of support sections. Multiple fixing plates 6 are evenly fixed between the fifth crossbeam 15 and the sixth crossbeam 16. The two sets of support sections are symmetrically arranged on the fixing plates 6. These two sets of support sections secure multiple box panels 5 to both sides of the movable frame 1, ensuring stable and reliable placement of the box panels 5 and allowing for partitioned placement. Each set of support sections includes a support crossbeam 21 and multiple support columns 22. The bottoms of the multiple support columns 22 are respectively fixed to the fixing plates 6, and the tops of the multiple support columns 22 are fixedly connected to the support crossbeam 21. The upper part of the innermost box panel 5 contacts the support crossbeam 21. In this embodiment, the support crossbeam 21 and multiple support columns 22 have a simple structure and are independently installable, resulting in high processing efficiency and easy assembly and disassembly onto the movable frame 1, eliminating the need for on-site drilling and welding. The upper part of the innermost box panel 5 contacts the supporting beam 21. Since multiple box panels 5 located on the same side are placed in sequence, the weight of all box panels 5 on the same side is ultimately borne by the supporting beam 21 and multiple supporting columns 22.
[0043] Furthermore, both the fifth crossbeam 15 and the sixth crossbeam 16 are provided with first fixing holes, and the fixing plate 6 is provided with second fixing holes. The first fixing holes and the second fixing holes are fixedly connected by a fourth bolt and a third nut, thereby fixing the fixing plate 6 to the fifth crossbeam 15 and the sixth crossbeam 16. The middle of both supporting crossbeams 21 and multiple fixing plates are provided with fourth mounting holes. Each supporting column 22 has a fourth inner thread nut 74 at its two ends. A fifth bolt passes through the fourth mounting hole and is fixedly connected to the fourth inner thread nut 74, thereby fixing the bottom of the supporting column 22 to the fixing plate 6 and the top of the supporting column 22 to the supporting crossbeam 21. Both ends of both supporting crossbeams 21 are provided with fifth mounting holes. Each supporting longitudinal beam 23 has a fifth inner thread nut 75 at its two ends. A sixth bolt passes through the fifth mounting hole and is fixedly connected to the fifth inner thread nut 75, thereby connecting the two supporting crossbeams 21. The fourth inner thread nut 74 and the fifth inner thread nut 75 are both M8×40×40 square tube inner thread nuts. Among them, the second inner thread nut 72, the third inner thread nut 73, the fourth inner thread nut 74 and the fifth inner thread nut 75 have the same structure.
[0044] As one possible implementation, a supporting longitudinal beam 23 is fixedly connected to both ends of the two supporting crossbeams 21. The supporting crossbeams 21 and the supporting longitudinal beams 23 are on the same horizontal plane. The supporting longitudinal beams 23 strengthen the structural strength between the two supporting crossbeams 21, allowing the two sets of support parts to better support the box plate 5. A second plug 24 is provided in the openings at both ends of the two supporting crossbeams 21. The second plug 24 is embedded in the openings at both ends of the supporting crossbeams 21. The second plug 24 also prevents bumps and scratches to workers and has an aesthetic function.
[0045] In one possible implementation, the liner structure 3 includes a first liner 31, a second liner 32, a third liner 33, and a fourth liner 34; the first liner 31 is fixedly disposed on the first crossbeam 11, the third crossbeam 13, the fifth crossbeam 15, and a portion of the reinforcing beam 17 located between the third crossbeam 13 and the fifth crossbeam 15; the second liner 32 is fixedly disposed on the second crossbeam 12, the third crossbeam 13, the fifth crossbeam 15, and a portion of the reinforcing beam 17 located between the third crossbeam 13 and the fifth crossbeam 15; the third liner 33 is fixedly disposed on the first crossbeam 11, the fourth crossbeam 14, and the sixth crossbeam. 16 and the partial reinforcing beam 17 located between the fourth crossbeam 14 and the sixth crossbeam 16; the fourth liner 34 is fixedly mounted on the second crossbeam 12, the fourth crossbeam 14, the sixth crossbeam 16 and the partial reinforcing beam 17 located between the fourth crossbeam 14 and the sixth crossbeam 16; gaps are left between the ends of the first liner 31 and the second liner 32 and between the ends of the third liner 33 and the fourth liner 34. When there is an assembly error between the first liner 31, the second liner 32, the third liner 33 and the fourth liner 34, their assembly positions can be adjusted through the gaps to minimize the assembly error.
[0046] In this embodiment, the first liner 31, the second liner 32, the third liner 33, and the fourth liner 34 of the liner structure 3 have a simple structure and are independently installable, resulting in high processing efficiency and easy assembly and disassembly onto the mobile frame 1, eliminating the need for on-site drilling and welding. The arrangement of the first liner 31, the second liner 32, the third liner 33, and the fourth liner 34 strengthens the structural strength of the mobile frame 1, improving its overall planar load-bearing capacity. The first liner 31, the second liner 32, the third liner 33, and the fourth liner 34 are made of wood, thereby enhancing the protection of the box panel 5 and preventing damage to the box panel 5.
[0047] Furthermore, the second self-drilling self-tapping screw is driven into the first liner plate 31 and then into the first crossbeam 11, the third crossbeam 13, and part of the reinforcing beam 17; the third self-drilling self-tapping screw is driven into the second liner plate 32 and then into the second crossbeam 12, the third crossbeam 13, and part of the reinforcing beam 17; the fourth self-drilling self-tapping screw is driven into the third liner plate 33 and then into the first crossbeam 11, the fourth crossbeam 14, and part of the reinforcing beam 17; the fifth self-drilling self-tapping screw is driven into the fourth liner plate 34 and then into the second crossbeam 12, the fourth crossbeam 14, and part of the reinforcing beam 17.
[0048] The components of the rack in this embodiment are detachable, and each component can be packaged separately or in batches, ultimately achieving low shipping and relocation costs. This solves the problems of difficult transportation of components, space occupation during placement, high manufacturing difficulty, and high shipping and relocation costs in the traditional rack production process.
[0049] In one possible implementation, the limiting part 4 includes multiple limiting strips 41. These limiting strips 41 ensure stable and reliable placement of the box panels 5 and allow for multi-row placement in designated areas. The multiple limiting strips 41 are evenly fixed to the first liner 31, the second liner 32, the third liner 33, the fourth liner 34, and between the ends of the first liner 31 and the second liner 32, and between the ends of the third liner 33 and the fourth liner 34, using first self-drilling self-tapping screws 42. The multiple limiting strips 41 are arranged sequentially along the width direction of the movable frame 1. The limiting strips 41 provide lateral restraint to the box panels 5, increasing the stability of their placement. The distance between two adjacent limiting strips 41 is greater than the width of the lower part of the box panel 5. The lower parts of multiple box panels 5 located on the same side of the movable frame 1 are sequentially placed between adjacent limiting strips 41. In other words, the adjacent limiting strips 41 limit the movable range of the lower part of the box panel 5. In extreme cases, such as when turning or going over potholes, if the panel 5 shakes, the two adjacent limiting strips 41 can limit the position of the lower part of the panel 5. The lower part of the panel 5 can only sway slightly between the two adjacent limiting strips 41. After the swaying is complete, the panel 5 remains stable between the two limiting strips 41 and does not fall off, thus preventing the panel 5 from being bumped or scratched after falling off.
[0050] Furthermore, the limiting strip 41, the first liner 31, the second liner 32, the third liner 33 and the fourth liner 34 are provided with positioning holes for the first self-drilling self-tapping screw to pass through.
[0051] In one possible implementation, the limiting strip 41 is provided with a first pin hole, and the first liner 31, the second liner 32, the third liner 33, and the fourth liner 34 are each provided with a second pin hole at a position corresponding to the first pin hole. The positioning pin 43 passes through the first pin hole and into the second pin hole. The positioning pin 43 can quickly position the limiting strip 41, eliminating the need for the limiting strip 41 to be located. Then, the limiting strip 41 is locked by the first self-drilling self-tapping screw 42, achieving rapid installation of the limiting strip 41.
[0052] In this embodiment, when the placement rack is used to transfer the box plates 5, the two sets of support parts and the multiple limiting strips 41 on the first liner 31, the second liner 32, the third liner 33, and the fourth liner 34 cooperate to fix the multiple box plates 5 to both sides of the movable frame 1. The box plates 5 on the same side are placed stably and reliably and are arranged in multiple rows. Specifically, the multiple box plates 5 to be transferred are divided into two parts and placed on both sides of the movable frame 1 respectively. The lower parts of the multiple box plates 5 on the same side of the movable frame 1 are placed between two adjacent limiting strips 41 in sequence, and the upper parts of the multiple box plates 5 on the same side of the movable frame 1 are in sequential contact, with the upper part of the innermost box plate 5 in contact with the support beam 21.
[0053] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
