Description

Technical Field

[0001] This utility model relates to the field of prepreg storage and transportation technology, specifically a prepreg low-temperature storage and transportation box. Background Technology

[0002] Prepreg storage and transportation require specialized cryogenic equipment to maintain performance and prevent damage from temperature changes and impacts, but existing equipment has significant shortcomings: First, it is inconvenient to move and position. Most wheeled equipment has no braking function, and it is easy to slide when loading, unloading or parking. Some of them are noisy when moving and consume a lot of power to push. Secondly, the sealing and insulation are poor. Most of them are single-seal designs, the seals are prone to aging and not fit tightly, and the low temperature loss is fast, which affects the quality of the prepreg. Third, there is insufficient material protection. The internal load-bearing structure is fixed and cannot be adjusted to separate the space as needed. It is easy to be stacked and squeezed, and there is a lack of cushioning components. The vibration during transportation causes the prepreg to shift and be damaged. Fourth, poor temperature control, cooling only in a single area, large temperature difference inside the chamber, difficulty in adjusting the cooling components, easy waste of resources or insufficient cooling; Fifth, the structure is unstable, the side door and internal components are not matched and limited, making it difficult to fit together after closing. The components are prone to shaking during transportation, which aggravates the collision of prepreg and shortens the equipment life. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please refer to the following: Figure 1-4 , A cryogenic storage and transport box for prepreg includes: Box 1 and side door 2, push handle 4 is fixedly connected to one side of the outside of box 1, and universal wheel 29 is provided at the bottom. Door handle 3 is fixed on side door 2, and rotating bolt 5 is provided on side door 2. Fixing sleeve 6 that fits into rotating bolt 5 is provided on the side of box 1 adjacent to side door 2. The material plate 11 and the support plate 13 are fixed inside the box 1. The support plate 13 is provided with a support groove 17 at the top, and the material plate 11 is provided with material plate grooves 23 at both ends and a material plate slider 25 at the bottom. The material plate grooves 23 are fitted with the box slider 16 on the inner side wall of the box 1, and the material plate slider 25 is fitted with the support groove 17. The material plate 11 is provided with a fixing plug 28 and a partition groove 24. The fixing plug 28 is adapted to the fixing groove 18 of the box 1. The freezer compartment 12 is located below the support plate 13. The support plate 13 has fixed sliders 21 at both ends. The top of the freezer compartment 12 has a freezer compartment groove 22 that is adapted to the fixed sliders 21. The freezer compartment 12 is divided into several compartments 20 by partitions 19. The freezer compartment 12 is fixed with a freezer compartment handle 27. The sealing assembly includes a sealing rubber gasket 7 and a sealing block 8 fixed to the side door 2, and a sealing groove 9 that fits into the sealing block 8 on the housing 1. And a partition buffer plate 10, which is detachably installed in the partition groove 24 of the material plate 11, and a large U-shaped groove 14 adapted to the material plate handle 26 and a small U-shaped groove 15 adapted to the freezer compartment handle 27 are provided on the inner side of the side door 2. Specifically, the main structure consists of a box 1 and a side door 2. The box 1 can be pushed by a handle 4, and the bottom component facilitates the movement of the box 1. The side door 2 is locked or unlocked with the box 1 by a specific component, realizing the opening and closing of the box 1. The internal material carrying component cooperates with the side wall and support component of the box 1 through a sliding groove, which can be flexibly pulled out to facilitate the placement or removal of prepreg. It can also be positioned by a fixing component to prevent displacement during transportation. The low-temperature storage component below the support component can also be pulled out by a sliding groove. Its internal partition design can classify and place cooling items to ensure the stability of the cooling items. When the side door 2 is closed, the sealing component fits into the corresponding structure of the box 1 to achieve the sealing of the box 1 and reduce temperature loss. The buffer partition on the material carrying component can be flexibly adjusted according to the size of the prepreg to separate the prepreg and avoid compression. The groove on the inside of the side door 2 accommodates the relevant handle when closed, further improving the stability of the internal structure. The whole structure works together to realize the low-temperature storage and safe transportation of the prepreg. In the embodiment: the partition buffer plate 10 is an elastic material component, and the number of partition buffer plates 10 is at least one, and a prepreg receiving area is formed between adjacent partition buffer plates 10; Specifically, the buffer dividers made of elastic material have a certain degree of elasticity. When the prepreg is placed in the space formed by adjacent buffer dividers, the elastic material can absorb the vibration during transportation. At the same time, by flexibly increasing or decreasing the number, it can accommodate prepreg of different sizes and quantities, preventing the prepreg from shaking or being squeezed in the box 1, and ensuring the integrity of the prepreg. In the embodiment: the number of freezer compartments 12 corresponds one-to-one with the number of material plates 11, and each freezer compartment 12 has 3-6 partition compartments 20; Specifically, the low-temperature storage components correspond one-to-one with the material-carrying components, meaning that there is a dedicated low-temperature supply source under each layer that carries the prepreg, which can ensure that the temperature of each layer in the box 1 is uniform and avoid local overheating that could affect the quality of the prepreg. The number of partitions in each low-temperature storage component is set so that different types of cooling items can be placed in a categorized manner, and the amount of cooling items can be adjusted according to the actual low-temperature requirements, ensuring the cooling effect while avoiding resource waste. In the embodiment: the sealing rubber gasket 7 is provided along the edge of the side door 2, and the thickness of the sealing rubber gasket 7 is 3-8mm. The sealing block 8 and the sealing groove 9 are interference fit. Specifically, the sealing rubber component set along the edge of the side door 2 can fit tightly against the edge of the box 1 when the side door 2 is closed, blocking the gap between the box 1 and the outside world and reducing the exchange of low-temperature air inside the box with hot air outside; the specific thickness design ensures the tightness of the seal, while the interference fit between the sealing block 8 and the sealing groove 9 further enhances the sealing effect. The double sealing structure together maintains the low-temperature environment inside the box 1 and prevents the temperature from rising rapidly. In this embodiment, an anti-slip structure is also included, with anti-slip textures on the upper surface of the material plate 11 and buffer bumps on the side of the partition buffer plate 10. Specifically, the anti-slip texture on the upper surface of the material-bearing component increases the friction between the prepreg and the bearing surface, preventing the prepreg from sliding due to vibration during transportation; the buffer protrusions on the side of the buffer separator can further fill the gap between the prepreg and the buffer separator, and absorb the impact force through the slight deformation of the protrusions during vibration. The dual function prevents the prepreg from shifting or colliding, ensuring transportation safety. In this embodiment: the caster wheel 29 is a silent caster wheel 29 with braking function, and there are 4 caster wheels 29, which are respectively set at the four corners of the bottom of the box body 1; Specifically, the silent moving component with braking function can roll flexibly when the box 1 needs to be moved, reducing moving resistance, and the silent design avoids noise during the movement; the number is set to four and distributed at the four corners of the bottom of the box 1 to ensure the stable support of the box 1 and prevent tipping; the braking function is activated after the box 1 reaches the designated position, which can fix the box 1, prevent the box 1 from sliding at will, and ensure the stability of the storage and loading and unloading process. In the embodiment: the box body 1 is made of thermal insulation composite board, which includes an outer metal plate, an inner moisture-proof board and a middle polyurethane insulation layer, with a thickness of 20-40mm. Specifically, the composite insulation board used in the box 1 has an outer metal plate that protects the box 1 and resists external impacts; an inner moisture-proof board that prevents moisture generated by the low temperature environment inside the box from penetrating into the board and avoids the board from getting damp and affecting the insulation effect; and a middle polyurethane insulation layer that, with its excellent insulation performance, can effectively block the heat transfer between the low temperature inside the box and the high temperature outside. The specific thickness design ensures the insulation effect and maintains the low temperature environment inside the box 1 for a long time, meeting the low temperature requirements for long-term storage and transportation of prepreg. Working principle: The push handle 4, in conjunction with the silent moving component with brake at the bottom, enables flexible movement and stable positioning; the side door 2 opens and closes with the help of the locking component, and when closed, it forms a double seal with the edge sealing rubber component and the corresponding sealing groove 9 and sealing block 8 to reduce temperature loss; the pull-out material carrying component inside the box cooperates with the box body 1 and the support component through the sliding groove, and the buffer partition component on it can be adjusted as needed to separate the prepreg and absorb vibration, and the anti-slip texture and buffer bumps further prevent the prepreg from shifting; the low temperature storage component below the support component can also be pulled out, and the internal partition design facilitates the flexible placement of cooling items, and corresponds one-to-one with the material carrying component to ensure uniform temperature inside the box; the inner groove of the side door 2 accommodates the relevant handles to improve internal stability. The whole system achieves low temperature storage and safe transportation of prepreg through the cooperation of various components.
