Description

Technical Field

[0001] The invention relates to the technical field of storage devices, in particular to a low-temperature storage box for transporting aquatic products. Background Art

[0002] Aquatic products require a certain living environment during transportation, so the transportation box is particularly important. Generally, low-temperature storage boxes are used for transportation. The current common low-temperature preservation method is to refrigerate with ice bags. The aquatic products are stacked and placed between ice bags, thereby keeping the aquatic products stored and transported in a low-temperature environment. Compared with equipment such as freezers, low-temperature storage with ice bags can save costs, and the storage box is smaller in size.

[0003] During long-term transportation, it is common for ice cubes in ice bags to melt due to the influence of the external environment. Although storage boxes generally have their own insulation layer, they still cannot prevent the melting of ice bags. Conventional storage boxes are stacked with aquatic products and ice bags. When the storage box is opened, the air in the box will be exchanged with the outside world, causing temperature loss. Therefore, it is difficult to directly take out the ice bag and replace it with a new one. After the ice cubes in the ice bag melt into water, they lose the low-temperature effect, thus affecting the freshness of the stored aquatic products. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a low-temperature storage box for transporting aquatic products to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. By placing elastic components, aquatic products and ice bags can be regularly stacked and placed to maintain a good low-temperature storage effect. The first sealing plate and the second sealing plate on the outside of the storage box can be used to take out the ice bags or aquatic products separately, so that the melted ice bags can be replaced to maintain the low temperature effect in the box and maintain the freshness of the aquatic products.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a low-temperature storage box for transporting aquatic products, comprising a bottom plate, a storage box is fixed on the top of the bottom plate, and a transverse partition is fixed laterally inside the storage box, three groups of longitudinal partitions are fixed longitudinally equidistantly inside the storage box, and the space surrounded by the longitudinal partitions and the transverse partitions is the storage space, and three groups of placement components are arranged above and below in the storage space of the storage box, the placement components include a sliding frame, the sliding frame is provided with two groups, and sliders are symmetrically slidably connected inside the sliding frame, a support plate is fixed to the outer end of the slider, an ice bag is arranged on the top of the placement component, a second sealing plate is arranged on the front and rear outer surfaces of the storage box corresponding to the placement component, a first sealing plate is arranged on the outer surface of the storage box corresponding to the position of the ice bag, a push-pull component is arranged on the outer surface of the first sealing plate and the second sealing plate, and the push-pull component includes two groups of vertical plates, and the two groups of vertical plates can be switched to be connected with the first sealing plate and the second sealing plate.

[0006] Furthermore, the outer periphery of the storage box is sleeved with a heat-insulating sleeve, the bottom plate is located on the outer circle of the storage box and is provided with an adhesive layer, and the bottom of the heat-insulating sleeve is connected to the adhesive layer.

[0007] Furthermore, the placement component also includes a moving block, and sliding grooves are opened on the inner walls of the vertical plate and the storage box, and a moving block is fixed inside the sliding groove at the position corresponding to each layer of the sliding frame, and the moving block slides along the sliding groove. The moving blocks on both sides of the placement component at the bottom of the storage box are fixed inside the sliding groove, and springs are fixed between adjacent sliding grooves.

[0008] Furthermore, a limiting frame is fixed on the outer surface of the moving block, and the sliding frame slides along the inside of the limiting frame.

[0009] Furthermore, the elastic component also includes a strap, the front and rear ends of the ice bag are bound with straps, and the outside of the straps are fixed with connecting ropes, and adjacent straps are fixedly connected by connecting ropes, and insertion strips are fixed on both sides of the first sealing plate, and the insertion strips are slidably inserted into the inner walls on both sides of the storage box, and the two ends of the connecting rope slide out from the inside of the insertion strips.

[0010] Furthermore, two winding seats are symmetrically mounted on the middle surface of the first sealing plate, and the two ends of the connecting rope are respectively wound inside the two winding seats. A knob is fixed on the outer end of one of the winding seats on the outer surface of the first sealing plate, and the knob is connected to the winding shaft of the winding seat.

[0011] Furthermore, gears are installed on the outer ring surface of the winding seat, and adjacent gears are meshed and connected.

[0012] Furthermore, the longitudinal partition is provided with a movable notch corresponding to the position through which the connecting rope passes, and the connecting rope slides along the movable notch.

[0013] Furthermore, the push-pull assembly also includes a first sealing plate and a second sealing plate located on the surfaces of both sides of the vertical plate, and ear plates are fixed with plug holes on the surfaces of the ear plates. Positions corresponding to the plug holes on both sides of the vertical plate are fixed with plug posts, and the plug posts can be alternately inserted into the plug holes on both sides.

[0014] Furthermore, metal grooves are provided on the outer surfaces of the top and bottom of the vertical plates of the storage box, and magnetic blocks are fixed on the top and bottom of the vertical plates, and the magnetic blocks can be adsorbed inside the metal grooves.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention covers the outer side of the storage box after the aquatic products and ice packs are placed in the storage box, thereby slowing down the loss of temperature in the storage box. The insulation cover is fixed by bonding with the adhesive layer on the bottom plate, which makes it convenient to insert and remove the storage box and also provides better protection for the storage box.

[0017] 2. The present invention allows the support plates inside the two sliding frames to be adjusted in position by sliding along the inside of the sliding frames through sliders. The distance between the two support plates is adjusted according to the size of the stored aquatic products, and the bottom middle position of the aquatic products is exposed as much as possible, so as to facilitate contact with ice bags for low-temperature storage. The height of each group of placement components can be adjusted by sliding the moving block pressure along the slide groove, and can be used to store different aquatic products.

[0018] 3. The present invention rotates the knob, and the two gears mesh and rotate, and the winding shaft of the winding seat winds up the connecting rope from both sides, so that the connecting rope inside the storage box is tightened, and the ice bags at the same height are kept in the same straight line due to the tightening of the connecting rope, which is convenient for taking out and replacing from the position of the first sealing plate. The two ends of the ice bag are inserted into the inside of the strap to fix the ice bag. After sending the ice bag into the upper layer of the placement component, the connecting rope is unwound through the winding seat, and the connecting rope is kept in a relaxed state. At this time, the ice bag can adjust itself according to the size and height of the aquatic product on the placement component, and contact with the top of the aquatic product. The ice bag on the lower layer of the placement component contacts the bottom of the aquatic product, thereby maintaining a good low-temperature storage effect and separating the aquatic products in the same storage cavity from each other.

[0019] 4. In the present invention, because the ear plates on the first sealing plate and the second sealing plate are at different positions, and the positions of the ear plates are also respectively located on both sides of the vertical plate, the vertical plate is provided with pins corresponding to the ear plates at different positions of the first sealing plate and the second sealing plate, and the top and bottom of the vertical plate can move along the metal groove to complete the plug-in locking with the first sealing plate or the second sealing plate. When the vertical plate is in the middle position, the pins on both sides of the vertical plate are not connected to the ear plates of the first sealing plate and the second sealing plate. At this time, the first sealing plate and the second sealing plate can be fixed to the storage box by screws. When the pins of the vertical plate are inserted into the sockets of the first sealing plate, all the first sealing plates and ice bags are pulled out by the vertical plate to replace the ice bags. When the pins of the vertical plate are inserted into the sockets of the second sealing plate, all the second sealing plates and the placement components are pulled out by the vertical plate to take out or place the aquatic products. The processes of replacing the ice bags and putting in or taking out the aquatic products are relatively independent and do not interfere with each other, thereby improving the convenience of replacing the ice bags.

[0020] 5. Compared with the prior art, the present invention can regularly stack aquatic products and ice bags by placing elastic components to maintain a good low-temperature storage effect. The first sealing plate and the second sealing plate on the outside of the storage box can be used to take out the ice bags or aquatic products separately, so that the melted ice bags can be replaced to maintain the low temperature effect in the box and maintain the freshness of the aquatic products.
