Abstract
Description
Technical Field
[0001] This utility model relates to the field of fresh food transport boxes, and in particular to a low-temperature fresh food transport box for shrimp and crabs. Background Technology
[0002] Shrimp and crab are popular aquatic products with high economic and nutritional value. However, shrimp and crab are perishable foods and easily spoil at room temperature after leaving their suitable living environment. Therefore, effective preservation and transportation are crucial for maintaining the quality of shrimp and crab, extending their shelf life, and reducing economic losses. This ensures that shrimp and crab maintain their freshness and taste when they arrive at consumers' hands smoothly from the place of origin.
[0003] Existing low-temperature preservation transport boxes for shrimp and crabs mainly rely on physical cooling and simple insulation to achieve preservation. Ice blocks are placed inside the box. The melting process of the ice blocks absorbs heat, lowering the temperature inside the box and creating a low-temperature environment for the shrimp and crabs, inhibiting their metabolism and microbial growth. The box body is mostly made of foam material, which has a low thermal conductivity and can slow down the transfer of external heat to a certain extent, maintaining a low temperature.
[0004] However, existing low-temperature preservation transport boxes for shrimp and crabs cannot be flexibly adjusted according to the size, quantity, and type of shrimp and crabs during transportation. Shrimp and crabs are prone to squeezing and colliding with each other. Therefore, a low-temperature preservation transport box for shrimp and crabs is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a low-temperature preservation and transportation box for shrimp and crabs, which aims to improve the problem that the existing technology cannot be flexibly adjusted according to the size, quantity and type of shrimp and crabs, and that shrimp and crabs are prone to squeezing and colliding with each other.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature preservation and transportation box for shrimp and crab, comprising a box body, a box door rotatably connected to the front side of the box body, a partition assembly provided inside the box body, and fixing assemblies provided on both sides of the box body. The partition assembly includes a storage box slidably connected to the inside of the box body, the surface of the storage box having multiple ventilation holes, a handle fixedly connected to the front side of the storage box, a slide rail fixedly connected to the inner wall of the box body, and a prompting mechanism provided on the front side of the storage box.
[0007] As a further description of the above technical solution: the fixing component includes a pull rod that is slidably connected to the side wall of the box, a spring is sleeved on the surface of the pull rod, a limit plate is fixedly connected to one end of the spring, and a limit groove is opened inside the box;
[0008] As a further description of the above technical solution: the prompting mechanism includes a push rod slidably connected inside the storage box, a rack fixedly connected to one end of the push rod, a gear provided at the bottom of the rack, the gear meshing with the rack, a protective shell fixedly connected to the front side of the storage box, and a turntable rotatably connected inside the protective shell;
[0009] As a further description of the above technical solution: the storage box is slidably connected inside the slide rail, and the rack is slidably connected inside the storage box;
[0010] As a further description of the above technical solution: the gear is rotatably connected inside the storage box, and the gear is fixedly connected to the rear side of the turntable;
[0011] As a further description of the above technical solution: the turntable is rotatably connected to the surface of the storage box;
[0012] As a further description of the above technical solution: the limiting plate is slidably connected inside the storage box, and the limiting plate is slidably connected inside the limiting groove;
[0013] As a further description of the above technical solution: one end of the spring is fixedly connected to the inside of the box, and an ice pack is provided in the storage box between the two fixed components.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, through the structural arrangement of the partition component and the design of the push rod, gear, and rack, the transmission gear rotates when the push rod is pushed, and the rotation of the gear drives the turntable to rotate, so that the turntable rotates to the corresponding shrimp and crab marking position, which facilitates the staff to classify and identify them. The setting of storage boxes and ventilation holes allows one type of shrimp and crab to be stored in the corresponding storage box, which solves the problem in the prior art that it cannot be flexibly adjusted according to the size, quantity, and type of shrimp and crab, and that shrimp and crab are prone to squeezing and colliding with each other.
[0016] 2. In this utility model, through the structural design of the fixing component, pulling the pull rod can compress the spring, allowing the limiting plate to enter the limiting groove, facilitating the removal or placement of the storage box. Releasing the pull rod resets the spring, and the limiting plate is embedded in the storage box, which can stably fix the storage box and facilitate transportation. Utilizing the elasticity of the spring and the design of the pull rod, operators can easily fix and unlock the storage box by simply pulling and releasing the pull rod. The operation is convenient and labor-saving, enhancing the practicality of the shrimp and crab low-temperature preservation transportation box. Attached Figure Description
