Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics, in particular to a cold chain logistics layered fresh-keeping device. Background Technique

[0002] Cold chain logistics is a professional logistics method that uses technologies such as temperature control and fresh-keeping, and equipment such as cold storages, refrigerated trucks, and refrigerated containers to ensure that cold chain products are always in a specified low-temperature environment throughout the whole process of primary processing, storage, transportation, distribution processing, sales, and distribution. The applicable scope of cold chain logistics includes: primary agricultural products, processed foods, special commodities, etc. Therefore, it has higher and more complex requirements than general normal-temperature logistics systems, and the construction investment is also much larger. It is a huge systematic project.

[0003] In the prior art, a patent document with the publication number of CN217497165U discloses a layered fresh-keeping device for cold chain logistics, including a fresh-keeping box body. The inside of the jacks opened at both ends of the top of one of the plastic support frames is movably penetrated by support plates respectively. The bottom ends of the two support plates are respectively movably penetrated through the jacks opened at both ends of the top of the other plastic support frame. Limiting holes are opened in the middle of both sides of the two plastic support frames, and iron inserts are movably penetrated through the four limiting holes.

[0004] It is found in the use process that when taking the items in the lower layer inside the fresh-keeping box body, it is necessary to take out the items above the fresh-keeping box body in turn first, and the convenience needs to be further improved. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a cold chain logistics layered fresh-keeping device with improved convenience.

[0006] A cold chain logistics layered fresh-keeping device of the utility model includes a fresh-keeping box body, a fresh-keeping box door, a support plate and a chute. The front end of the fresh-keeping box body is movably provided with a fresh-keeping box door through a hinge. Multiple pairs of support plates are arranged inside the fresh-keeping box body, and a group of chutes are respectively arranged on each group of support plates. The device further includes a support plate assembly, and the support plate assembly can be fixedly and slidably arranged in a pair of chutes; during use, according to the height of the items to be refrigerated, the distance between the two support plate assemblies can be adjusted. When it is necessary to take the items on the support plate assembly, the staff opens the fresh-keeping box door, and then the corresponding items can be taken, reducing the interference of multiple groups of support plate assemblies on the taking of items and improving the convenience.

[0007] Preferably, the support plate assembly includes a support plate, grooves, rollers, a pull plate, and a clamping assembly. On the left and right sides of the bottom end of the support plate, a set of grooves is respectively arranged. In each set of grooves, multiple sets of rollers are rotatably arranged. At the front end of the support plate, a pull plate is arranged. On the left and right ends of the pull plate, a set of clamping assemblies is respectively arranged. On the left and right ends inside the fresh-keeping box body, multiple sets of card slots are respectively arranged. When adjusting the height of the support plate, insert the left and right ends of the support plate into the two sets of sliding grooves respectively. The rollers roll in the sliding grooves, thereby improving the convenience of installation and disassembly of the support plate. After the support plate is installed, operate the two sets of clamping assemblies on the pull plate to be respectively clamped with a set of card slots, thereby completing the fixation of the support plate, improving convenience and flexibility.

[0008] Preferably, the clamping assembly includes a concave groove, a smooth rod, a moving block, a spring, and a plug rod. At the front end of the pull plate, a concave groove is arranged. In the concave groove, two sets of smooth rods are fixedly arranged. The moving block is slidably connected with the two sets of smooth rods. At the outer end of the moving block, a plug rod is arranged. The plug rod extends to the outside of the pull plate. At the end of the moving block away from the plug rod, a spring is arranged. During use, the support plate slides backward in the two sets of sliding grooves. Operate the two sets of moving blocks to move closer mirror-symmetrically. When the two sets of plug rods respectively coincide with the two sets of card slots, the staff releases the two sets of moving blocks. The two sets of moving blocks move away mirror-symmetrically under the action of the elastic force of the two sets of springs, so that the two sets of plug rods are respectively inserted into the two sets of card slots to complete the fixation of the support plate and the pull plate.

[0009] Preferably, it further includes a handle. At the front end of the pull plate, a set of handles is arranged. The staff pulls the pull plate through the handle, improving convenience.

[0010] Preferably, it further includes a buffer pad. At the rear end of the support plate, a buffer pad is arranged. When the support plate is installed, the rear end of the support plate contacts the inner rear end of the fresh-keeping box body through the buffer pad, reducing the hard collision between the support plate and the fresh-keeping box body.

[0011] Preferably, it further includes a hand slot and a buckle plate. On the left and right ends of the fresh-keeping box body, hand slots are respectively arranged. In each set of hand slots, a set of buckle plates is respectively arranged. The staff puts their hands into the hand slots and holds the buckle plates to carry the fresh-keeping box body, improving convenience.

[0012] Preferably, it further includes adjustable feet. At the four corners of the bottom end of the fresh-keeping box body, a set of adjustable feet is respectively arranged. The four sets of adjustable feet cooperate with each other to stably support the fresh-keeping box body, improving stability.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: During use, according to the height of the items to be refrigerated, adjust the distance between the two sets of support plate assemblies. When it is necessary to take the items on the support plate assembly, the staff opens the fresh-keeping box door and can take the corresponding items, reducing the interference of multiple sets of support plate assemblies on the taking of items and improving convenience.
