Description

Technical Field

[0001] This invention relates to the field of supply box technology, and more specifically, to a supply box that facilitates modular transportation. Background Technology

[0002] In naval replenishment and transfer operations, modular replenishment frames are the core equipment for carrying, storing, and transferring various supplies, and are widely used in shipboard supply storage, at-sea replenishment, and supply transfer. These frames adopt a modular unit structure design, allowing for flexible stacking and combination according to the volume of supplies to be transferred, effectively improving the utilization rate of shipboard space and adapting to the complex and high-frequency supply transfer needs of ships. Because ships experience turbulence and swaying during navigation, and maritime supply transfer is characterized by batch processing and continuity, the locking stability of stacked replenishment frames, the ease of stacking and disassembly, and the degree of automation directly determine the efficiency of shipboard supply transfer and the safety of supply storage; these are the core technical indicators of modular replenishment frame design.

[0003] Currently, the modular supply crates used for shipboard material transfer in existing technologies are generally assembled using manual locking and unlocking methods. After stacking multiple supply crate units layer by layer, workers need to manually operate the corresponding latches and locks on each crate to secure the upper and lower supply crate units. When it is necessary to disassemble the stacked supply crates for material handling and transfer, workers also need to manually unlock each locking structure in advance to release the locking state between the multiple layers of supply crates before a forklift can be used to complete the disassembly and transfer operation. This method can lock the stacked modular supply crates, but the operation steps are cumbersome and time-consuming, significantly increasing the labor cost and operation time of stacking and assembly. In addition, before the stacked supply crates are disassembled, workers need to manually pre-unlock each locking structure in advance, which cannot be completed simultaneously with the loading and unloading of forklifts. The transfer process is cumbersome and has a low degree of automation.

[0004] In view of this, we propose a supply frame that facilitates modular transportation. Summary of the Invention

[0016] Beneficial effects One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. When using this modular transport supply frame to transfer materials according to the ship's usage requirements, after two supply frame units are stacked, when the forklift is removed, both return springs return to their natural state, causing the latching bracket to engage with the latching seat, thus achieving a self-locking effect on the stacked supply frame units. This eliminates the need for manual locking of the stacked supply frame units by personnel. Furthermore, when the two return springs return to their natural state, they also cause the two drive plates to reset. When unloading the stacked supply frame units, the two forks of the forklift contact the two drive plates respectively, causing the latching bracket to disengage from the latching seat. This facilitates unloading the stacked supply frame units without requiring manual pre-unlocking by personnel, improving the portability of this modular transport supply frame.

[0017] 2. Through the design of the protective shell, which is fitted over the return spring, the return spring is protected and is not directly exposed to the ambient air. This effectively prevents the spring from being corroded by salt spray in the high humidity environment of the ocean during long-term voyages, thus avoiding the formation of pits on the surface and stress concentration that leads to elasticity decay. As a result, the service life of the return spring and the overall service life of the positioning components are improved, which helps to improve the portability of the supply frame in this modular transportation system.

[0018] 3. Through the design of the emergency adjustment component, when the return springs experience a decrease in elasticity after long-term use and repeated expansion and contraction, and the two return springs cannot return to their original state, the operator can insert their hand under the supply frame unit and rotate the adjustment rod. This will cause the two locking brackets to engage with the two locking seats respectively, and the pawls to engage with the ratchet, locking the adjustment rod. This effectively prevents the rotating shaft from rotating in the opposite direction and causing the two pull ropes to unfold, thus ensuring that the two locking brackets remain engaged with the two locking seats. This ensures the locking effect on the stacked supply frame units, achieving an emergency locking effect on the two supply frame units when the return springs are damaged, and improving the stability of the supply frame in this modular transportation system.

[0019] 4. With the design of the elastic cord, when in use, the elastic cord pulls the pull cord inside the protective shell, keeping the pull cord between the outside of the protective shell and the storage tray taut. This prevents the pull cord from falling off to the outside of the storage tray, thus preventing the storage tray from being unable to wrap around the pull cord when the two supply box units are locked in an emergency. This helps to ensure the stability of the emergency adjustment component.

[0020] 5. Through the design of the moving plate, locking rod, pull rope two, and elastic rope three, when the return spring experiences a decrease in elasticity after long-term use and repeated expansion and contraction, the emergency adjustment component allows the two locking brackets to engage with the two locking seats respectively. The locking rod engages with the rotating shaft, fixing the shaft position and ensuring that the two locking brackets remain engaged with the two locking seats. Simultaneously, when the moving plate slides towards the rotating shaft, pull rope two pulls the pawl to rotate on the mounting bracket, canceling the engagement between the pawl and ratchet, thus removing the limit on the adjusting rod. This effectively prevents the pawl and ratchet from engaging and locking the adjusting rod, thereby locking the rotating shaft position. Furthermore, the two pull ropes one lock the transmission plate position, thus locking the rotating shaft position. This prevents the forklift's two forks from contacting the two drive plates, causing damage to the drive plates, further improving the stability of the positioning component.

[0021] 6. By setting the transmission plate including sliding plate one and sliding plate two, when the return spring is damaged and needs to be replaced, the connection plate one and sliding plate two are disassembled, the two sliding seats are disassembled separately, and then the cover plate on the top of the protective shell is disassembled. This allows the connection plate one to be disassembled from the sliding seat and the connection plate two to the sliding plate one. Thus, sliding plate one can be pulled out from the protective shell, and the return spring can be disassembled and replaced. The operation is simple and convenient for disassembling and replacing the return spring.

[0022] 7. Through the special design of the snap-fit ​​seat, including a disc and a snap-fit ​​block, the longitudinal section of the snap-fit ​​block is an isosceles trapezoid. When the supply frame unit is lifted and stacked by a forklift, when the clearance hole at the bottom of the support base contacts the inclined surface at the top of the snap-fit ​​block, the inclined surface at the top of the snap-fit ​​block guides the support base, thereby preventing the stacking of two supply frame units. Utilizing the special design of the disc being inserted into the clearance hole and fitting snugly with the cross-section of the support base, the disc limits the position of the support base during material transfer using this supply frame, effectively preventing horizontal displacement of the supply frame unit. This effectively prevents the snap-fit ​​frame from disengaging from the snap-fit ​​seat due to horizontal displacement of the supply frame unit, further improving the transfer stability of the supply frame unit.

[0042] Reference Figures 1 to 15 This invention provides a supply box that facilitates modular transportation, comprising: The system includes a fixed base and several supply frame units 1, each comprising a base 11 and a frame 12. The base 11 includes a fixed frame 111, with a bottom plate 112 and a top plate 113 welded to the top and bottom of the fixed frame 111, respectively. It is worth noting that the frame 12 is open on all four sides and the top, facilitating the retrieval of materials from the supply frame unit 1. The frame 12 is hinged with frame doors 13 to seal the openings in the frame 12, achieving the sealing effect. The frame doors 13 are equipped with mounting plates 14 for installing RFID tags, facilitating the recording of inventory information and its writing into the RFID tags using a handheld terminal in the information management system during manual inventory handling, thus facilitating the subsequent retrieval of inventory information. The frame doors 13 are fixed to the frame 12 by spring pins, facilitating the fixing or unfixing. Several drainage holes are provided on the bottom plate 112 and the top plate 113 to facilitate the drainage of materials placed inside the supply frame unit 1. Card holder assembly 2, there are two sets, the two sets of card holder assembly 2 are symmetrically arranged on the top of the frame 12, the card holder assembly 2 includes card receiving seats 21 symmetrically fixed to the top of the frame 12; The support assembly 3 includes support units symmetrically arranged on the bottom of the base plate 112. Each support unit includes a support seat 31 symmetrically welded to the bottom of the base plate 112. Several observation ports are opened on the outer periphery of the support seat 31, all of which are connected to its interior. The bottom of the support seat 31 is provided with a clearance through hole 32. The four snap-fit ​​seats 21 can pass through the four clearance through holes 32 and extend into the interior of the support seat 31. Multiple auxiliary support frames are welded to the bottom of the base plate 112 and between the two sets of support units. The bottom of the auxiliary support frames and the bottom of the support seat 31 are on the same water surface. When the two supply frame units 1 are stacked, the auxiliary support frames are attached to the top of the frame 12, which improves the stacking stability of the two supply frame units 1. Positioning components 4, in two sets, are symmetrically arranged on the base plate 112, and each set of positioning components 4 corresponds to one set of card holder components 2. The positioning assembly 4 includes a retaining sleeve component 41, a self-resetting transmission component 42, and a driving component 43. The retaining sleeve components 41 are symmetrically rotatably connected to the base plate 112. The retaining sleeve components 41 can be fitted onto the outside of the retaining seat 21 and engage with it. The base plate 112 is equipped with self-resetting transmission components 42 that are connected to both sets of retaining sleeve components 41. The bottom of the base plate 112 is equipped with a driving component 43 connected to the self-resetting transmission components 42. The end of the driving component 43 extends to the lower part of the middle of the base plate 112. The driving component 43 is used to drive the self-resetting transmission component. When component 42 is activated, the two sets of retaining sleeve components 41 rotate, thereby canceling the engagement between the retaining sleeve components 41 and the retaining seat 21. Specifically, when the self-resetting transmission component 42 is in its original state, the retaining sleeve components 41 are engaged with the retaining seat 21, and the ends of the two sets of driving components 43 away from the self-resetting transmission component 42 are located on the side where the two sets of driving components 43 are close to each other. When the two supply frame units 1 are stacked in two layers, the support component 3 is used to form a fork opening between the two supply frame units 1 for forklift forks to insert into. Figure 1 and Figure 3 As shown.

[0043] In the above scheme, when the supply boxes of this modular transport are used to transfer materials according to the needs of the ship, after the two supply box units 1 are stacked, when the forklift is removed, both return springs 429 return to their natural state, so that the latching bracket 413 and the latching seat 21 are latched, thereby achieving a self-locking effect on the stacked supply box units 1. It is not necessary for the staff to manually lock the stacked supply box units 1. Furthermore, when the two return springs 429 return to their natural state, they drive the two drive plates 434 to reset. When the stacked supply box units 1 are unloaded, when the two forks of the forklift abut against the two drive plates 434 respectively, the latching bracket 413 can be disengaged from the latching seat 21, which facilitates the unloading of the stacked supply box units 1. It is not necessary for the staff to manually pre-unlock the stacked supply box units 1, thus improving the portability of the supply boxes transported by this modular transport.

[0044] In this embodiment, the sleeve component 41 includes a fixing plate 411, and a second clearance hole is provided on the base plate 112. The fixing plate 411 is fixedly installed on the top of the base plate 112 and blocks the second clearance hole. A vertical rotating column 412 is rotatably installed on the fixing plate 411. The rotating column 412 moves through the second clearance hole and extends to the bottom of the base plate 112. A snap-fit ​​bracket 413 is integrally formed at the bottom of the rotating column 412. The snap-fit ​​bracket 413 can be sleeved on the outside of the snap-fit ​​seat 21 and snap-fit ​​with the snap-fit ​​seat 21. The self-resetting transmission component 42 is connected to both of the rotating columns 412.

[0045] In this embodiment, the self-resetting transmission component 42 includes a vertically rotatably mounted shaft 421 on a base plate 112. A drive gear 422 is coaxially fixed on the shaft 421 above the base plate 112. Sliding seats 428 are fixedly mounted on the top of the base plate 112 on both sides of the shaft 421. A transmission plate 423 is horizontally slidably mounted on the two sliding seats 428. A drive rack 424 that meshes with the drive gear 422 is fixedly mounted on the transmission plate 423. A connecting gear 425 is coaxially fixed on the rotating column 412 above the fixed plate 411. A transmission gear 426 that meshes with a connecting gear 425 is rotatably mounted on 411. A transmission rack 427 is symmetrically fixed on the transmission plate 423. The two transmission racks 427 mesh with the two transmission gears 426 respectively. A connecting plate 4281 is fixedly mounted on the side of the two sliding seats 428 that is far away from each other. A return spring 429 sleeved on the outside of the transmission plate 423 is fixedly mounted on the side of the connecting plate 4281 that is far away from the sliding seat 428. A connecting plate 4291 fixedly connected to the transmission plate 423 is fixedly mounted on the other end of the return spring 429. The driving component 43 is connected to the rotating shaft 421.

[0046] In this embodiment, the driving component 43 includes a fixing frame 431 welded to the bottom of the base plate 112. The fixing frame 431 is sleeved on the outside of the rotating shaft 421, and the bottom of the fixing frame 431 is flush with the bottom of the support base 31. A mounting frame 432 is fixedly installed on the inner side of the fixing frame 431, and the mounting frame 432 is rotatably connected to the rotating shaft 421. A connecting seat 433 is fixedly installed on the outside of the rotating shaft 421. A vertical driving plate 434 is fixedly installed on the other end of the connecting seat 433. Specifically, when both return springs 429 are in their natural state, the ends of the two driving plates 434 away from the rotating shaft 421 are located on the side where the two driving plates 434 are close to each other.

[0047] In this embodiment, the transmission plate 423 includes a first sliding plate 4231 and a second sliding plate 4232. The first sliding plate 4231 is slidably mounted on both sliding seats 428 in a horizontal direction. The second sliding plate 4232 is fixedly mounted on the opposite side of the two first sliding plates 4231 by screws. The driving rack 424 is fixedly mounted on the second sliding plate 4232. The two transmission racks 427 are respectively fixedly mounted on the two first sliding plates 4231. The first connecting plate 4281 is fixedly mounted on the sliding seat 428 by screws. The second connecting plate 4291 is fixed to the first sliding plate 4231 by screws.

[0048] In this embodiment, a protective shell 5 is fixedly installed on the sliding seat 428, which is sleeved on the outside of the connecting plate 4281, the return spring 429, and the connecting plate 4291. The sliding plate 4231 movably passes through the protective shell 5, and the cross-section of the sliding plate 4231 and the protective shell 5 are in contact. It is worth noting that the top of the protective shell 5 is open, and a cover plate for sealing the open end is fixedly installed on the top of the protective shell 5. In the above solution, through the design of the protective shell 5, the protective shell 5 is sleeved on the outside of the return spring 429, achieving the protection effect of the return spring 429, effectively avoiding direct exposure to the ambient air, thereby effectively avoiding the corrosion of the spring caused by salt spray in the high humidity environment of the ocean when the ship sails at sea for a long time, causing pitting on the surface and stress concentration leading to elastic decay. Therefore, the service life of the return spring 429 is improved, the overall service life of the positioning component 4 is improved, and the portability of the supply frame of this modular transportation is improved.

[0049] In this embodiment, an emergency adjustment component 6 connected to the rotating shaft 421 is installed on the fixed frame 431, and the emergency adjustment component 6 is connected to both connecting plates 4291. The emergency adjustment component 6 is used to drive the two connecting plates 4291 to move so that the two snap-fit ​​brackets 413 are snapped into the two snap-fit ​​seats 21 respectively. In the above scheme, through the design of the emergency adjustment component 6, when the return spring 429 has been used for a long time and has undergone repeated expansion and contraction, its elasticity decreases. When the two return springs 429 cannot return to their original state, the operator inserts his hand under the supply frame unit 1 and rotates the adjustment rod 64. This allows the two latching brackets 413 to engage with the two latching seats 21 respectively, and the pawl 67 to engage with the ratchet 66, locking the adjustment rod 64. This effectively prevents the rotating shaft 61 from rotating in the opposite direction and unfolding the two pull ropes 63, thus ensuring that the two latching brackets 413 remain engaged with the two latching seats 21 respectively. This ensures the locking effect on the stacked supply frame unit 1, achieving an emergency locking effect on the two supply frame units 1 when the return spring 429 is damaged, and improving the stability of the supply frame in this modular transportation system.

Elastic rope 3 4321 is symmetrically fixedly installed on the frame 432 and on the side of the rotating shaft 421 near the driving plate 434.

Pull rope 2 82 is wrapped around the bottom of the guide wheel 4322, and the other end of pull rope 2 82 is fixedly connected to the pawl 67.

[0052] In this embodiment, the fixing base includes two symmetrically arranged retention frames 9, and the top of each of the two retention frames 9 is symmetrically fixed with the snap-fit ​​seat 21; The snap-fit ​​base 21 includes a disc 211, with a connecting post integrally formed on the top of the disc 211. The top of the connecting post is integrally formed with a snap-fit ​​block 212 with an isosceles trapezoidal longitudinal section. The snap-fit ​​bracket 413 is sleeved on the snap-fit ​​block 212 and snaps into the snap-fit ​​block 212. The disc 211 can be inserted into the clearance through hole 32 and its cross section is in contact with the support base 31.

[0053] Working principle and usage process of this invention: When transferring materials using this modular transport supply frame according to the ship's operational needs, after placing the materials inside the supply frame unit 1, a forklift is used to lift one supply frame unit 1 and place it on top of the other supply frame unit 1. When stacking the two supply frame units 1, the forklift forks are inserted between the two sets of support units at the bottom of one of the supply frame units 1 to lift it. When the two forks of the forklift abut against the two drive plates 434, the drive plates 434 cause the rotating shaft 421 to rotate on the base plate 112, driving the drive gear 422 to rotate, which in turn drives the drive rack 424 to rotate. The transmission plate 423 slides horizontally on the two sliding seats 428, causing the two transmission racks 427 to translate, thereby causing the two transmission gears 426 to rotate synchronously on the two fixed plates 411 respectively. Through the two connecting gears 425, the two rotating columns 412 are driven to rotate synchronously, thereby causing the snap-fit ​​bracket 413 to rotate around the rotating column 412. During this period, when the transmission plate 423 is displaced, it causes the two sliding plates 4231 to slide on the two sliding seats 428 respectively, thereby causing the two connecting plates 4291 to move synchronously. At this time, one of the return springs 429 contracts and the other return spring 429 stretches. When a forklift lifts supply frame unit 1 onto another supply frame unit 1 for stacking, the clearance holes 32 in the four support seats 31 at the bottom of the lifted supply frame unit 1 are respectively positioned above the four locking seats 21. When the forklift lowers the lifted supply frame unit 1 for stacking, the four locking seats 21 are inserted into the inside of the support seats 31 through the four clearance holes 32. When the four support seats 31 at the bottom of the upper supply frame unit 1 are in contact with the top of the lower supply frame unit 1, the stacking of the two supply frame units 1 is completed. After the two supply frame units 1 are stacked, when the forklift is removed and the forklift forks are no longer in contact with the two drive plates 434, the two return springs 429 return to their natural state, causing the two sliding plates 4231 to be respectively positioned on the two sliding seats 42. The sliding reset mechanism 8 drives the rotating column 412 to rotate and reset, causing the latching bracket 413 to engage with the latching seat 21, thus achieving a self-locking effect on the stacked supply box unit 1. This eliminates the need for manual locking of the stacked supply box unit 1 by the operator. Furthermore, when the two reset springs 429 return to their natural state, they drive the two drive plates 434 to reset. When unloading the stacked supply box unit 1, the two forks of the forklift contact the two drive plates 434, causing the rotating shaft 421 to rotate. This, in turn, drives the latching bracket 413 to rotate via the rotating column 412, disengaging the latching bracket 413 from the latching seat 21. This facilitates unloading the stacked supply box unit 1 without requiring manual pre-unlocking by the operator, improving the portability of the supply box in this modular transportation system.

[0054] By designing the protective shell 5, which is fitted over the return spring 429, the return spring 429 is protected, effectively preventing direct exposure to ambient air. This effectively prevents corrosion of the spring caused by salt spray in the high-humidity marine environment during long-term voyages, thus avoiding stress concentration and elasticity attenuation. As a result, the service life of the return spring 429 and the overall service life of the positioning assembly 4 are improved, which helps to enhance the portability of the supply frame in this modular transportation system.

[0055] Through the design of the emergency adjustment component 6, the rotating shaft 61 is rotatably installed in the mounting hole in the rotating shaft 421. The rotation of the rotating shaft 421 drives the transmission plate 423 to slide, so that when the two connecting plates 4291 move synchronously, the two connecting plates 4291 respectively pull the ends of the two pull ropes 63 to move, so that the pull ropes 63 wrapped on the storage tray 62 unfold. The guide plate 65 limits the pull ropes 63, so as not to affect the sliding of the transmission plate 423. When the return spring 429 is used for a long time and undergoes repeated expansion and contraction, its elasticity decreases. When the two return springs 429 fail to return to their original state, the sliding distance of the transmission plate 423 on the two sliding seats 428 is shortened, resulting in a smaller rotation angle of the rotating column 412. This causes the latching bracket 413 to fail to effectively latch with the latching seat 21. After the two supply box units 1 are stacked and the forklift is removed, the worker observes through the observation port in the support seat 31 that the latching brackets 413 are not effectively latched. At this time, the worker inserts his hand under the supply box unit 1 and rotates it to adjust... The lever 64 drives the rotating shaft 61 to rotate via the bevel gear assembly, causing the two storage trays 62 to rotate synchronously and wind and coil the two pull ropes 63. This, in turn, drives the transmission plate 423 to slide and reset via the two connecting plates 4291, allowing the two locking brackets 413 to engage with the two locking seats 21 respectively. During this process, the rotation of the adjusting lever 64 drives the ratchet 66 to rotate synchronously, and the pawl 67 reciprocates on the mounting bracket 432 without affecting the rotation of the ratchet 66. When the transmission plate 423 slides and resets, it cannot rotate due to the influence of the two pull ropes 63. When the adjusting rod 64 is moved, the elastic rope 68 pulls the pawl 67 to rotate and reset on the mounting frame 432, so that the pawl 67 engages with the ratchet 66 and locks the adjusting rod 64. This effectively prevents the rotating shaft 61 from rotating in the opposite direction and unfolding the two pull ropes 63, thereby ensuring that the two snap-fit ​​frames 413 are snapped into the two snap-fit ​​seats 21 respectively. This ensures the locking effect on the stacked supply frame units 1, and achieves an emergency locking effect on the two supply frame units 1 when the reset spring 429 is damaged, thus improving the stability of the supply frame in this modular transportation system.

[0056] With the design of the elastic cord 7, when in use, the elastic cord 7 pulls the pull cord 63 inside the protective shell 5, and keeps the pull cord 63 between the outside of the protective shell 5 and the storage tray 62 in a taut state. This prevents the pull cord 63 from falling off to the outside of the storage tray 62, which would prevent the storage tray 62 from being able to wrap and store the pull cord 63 when the two supply box units 1 are locked in an emergency. This helps to ensure the stability of the emergency adjustment component 6 in use. Through the design of the movable plate 8, the locking rod 81, the second pull rope 82, and the third elastic rope 4321, when the return spring 429 experiences a decrease in elasticity after long-term use and repeated expansion and contraction, the emergency adjustment component 6 engages the two locking brackets 413 with the two locking seats 21 respectively. At this time, the rotating shaft 421 drives the drive plate 434 to reset. The ends of the two drive plates 434 away from the rotating shaft 421 are located on the side where the two drive plates 434 are close to each other. At this time, the third elastic rope 4321 pulls the movable plate 8 to slide towards the rotating shaft 421 on the mounting bracket 432, so that the end of the locking rod 81 is inserted into the locking hole 4211, and the locking rod 81 engages with the rotating shaft 421, fixing the position of the rotating shaft 421. This ensures that the two locking brackets 413 are engaged with the two locking seats 21 respectively. At the same time, when the movable plate 8 slides towards the rotating shaft 421... By pulling the second rope 82, the pawl 67 is rotated on the mounting bracket 432, so that the end of the pawl 67 does not contact the ratchet 66, canceling the engagement between the pawl 67 and the ratchet 66, thereby canceling the limit on the adjusting rod 64. At this time, the two elastic ropes 7 pull the two pull ropes 63 into the protective shell 5, so as not to affect the situation where the two forks of the forklift collide with the two drive plates 434 and push the drive plates 434 to rotate around the rotating shaft 421. This effectively avoids the situation where the pawl 67 and the ratchet 66 engage and lock the adjusting rod 64, thereby locking the position of the rotating shaft 61. Under the action of the two pull ropes 63, the position of the transmission plate 423 is locked, thereby locking the position of the rotating shaft 421. This would prevent the two forks of the forklift from collide with the two drive plates 434 and cause damage to the drive plates 434, thus further improving the stability of the positioning component 4.

[0057] By setting the transmission plate 423 with a special design including sliding plate one 4231 and sliding plate two 4232, when the return spring 429 is damaged and needs to be replaced, the sliding plate one 4231 and sliding plate two 4232 are disassembled, the two sliding seats 428 are disassembled respectively, and the cover plate on the top of the protective shell 5 is disassembled. This allows the connecting plate one 4281 to be disassembled from the sliding seat 428, and the connecting plate two 4291 to the sliding plate one 4231. Thus, the sliding plate one 4231 can be pulled out from the protective shell 5, and the return spring 429 can be disassembled and replaced. The operation is simple and convenient for disassembling and replacing the return spring 429.

[0058] By designing the holding frame 9, it is pre-installed in the cabin of the ship's hold during use. The top of the holding frame 9 is symmetrically fixed with the locking seat 21. When the supply frame is used to transfer materials, the supply frame unit 1 is lifted by a forklift and placed on the two holding frames 9. Similarly, the locking frame 413 in the lower supply frame unit 1 is locked with the locking seat 21 on the holding frame 9, thereby positioning the lower supply frame unit 1 and achieving a self-locking effect on the lower supply frame unit 1, thus improving the transfer stability of the supply frame unit 1. Through the special design of the latching seat 21, which includes a disc 211 and a latching block 212, the longitudinal section of the latching block 212 is an isosceles trapezoid. When the supply frame unit 1 is lifted and stacked by a forklift, when the clearance hole 32 at the bottom of the support seat 31 contacts the inclined surface at the top of the latching block 212, the inclined surface at the top of the latching block 212 guides the support seat 31, thereby avoiding stacking between the two supply frame units 1. Through the special design of the disc 211 being inserted into the clearance hole 32 and fitting with the cross section of the support seat 31, the disc 211 limits the position of the support seat 31 during the material transfer using this supply frame, effectively preventing the supply frame unit 1 from displacing horizontally, thereby effectively preventing the latching frame 413 from disengaging from the latching seat 21 due to horizontal displacement of the supply frame unit 1, further improving the transfer stability of the supply frame unit 1.
