Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present invention. It will be apparent that embodiments of the invention may be practiced without limitation to the specific details that are set forth by those skilled in the art.

The invention provides a split type heat preservation container, referring to fig. 1 to 6, the external shape of the split type heat preservation container is in a cuboid shape, a heat preservation layer is arranged on the inner wall of the split type heat preservation container, and the split type heat preservation container comprises a container body 100 and a bottom plate 200. The case 100 is configured as a case having an opening at the bottom, and specifically includes a front end frame 130, a rear end frame 140, a top plate 110, side plates 120, and a door 141. The bottom plate 200 is detachably coupled to the bottom opening of the case 100, and the bottom plate 200 includes a body 210 and a floor 211 protruding upward from the body 210, and in a state where the case 100 is coupled to the bottom plate 200, the floor 211 protrudes into the bottom opening and an outer circumferential side of the floor 211 is in sealing engagement with a bottom inner circumferential side of the case 100.

The split type thermal insulation container is formed by detachably combining the box body 100 and the bottom plate 200, and after the box body 100 and the bottom plate 200 are separated, a larger operation space for loading and unloading goods can be formed on the bottom plate, so that the loading and unloading efficiency of the goods can be improved, and the goods damage caused by collision can be prevented; by setting the appearance of the container body to be cuboid, the container meets the transportation requirement, and is beneficial to providing larger accommodating space for equipment such as instruments to be transported in the container; the heat preservation layer is arranged on the inner wall of the container, so that proper heat preservation conditions are provided for equipment such as instruments in the container, especially transportation of temperature-sensitive equipment is facilitated, and further, cargo damage caused by inconsistent temperature conditions is prevented; by arranging the sealing assembly 300 between the inner peripheral side surface of the bottom of the container body 100 and the outer peripheral side surface of the floor 211, the sealing assembly is used for filling the transverse gap at the joint of the container body 100 and the bottom plate, thereby blocking the temperature exchange between the inside and the outside of the container, further improving the heat insulation performance of the container, and ensuring the sealing consistency and the sealing effect between the bottom plate 200 and the container body 100 along the length direction of the container body when the loads on the bottom plate 200 along the length direction are different.

When the split type heat preservation container is used for transporting equipment sensitive to temperature conditions, the heat preservation effect is not enough, and refrigeration and better sealing and heat preservation functions are often needed. In this regard, referring to fig. 1, 2 and 5, the split type thermal insulation container of the present invention further includes a refrigerating unit 131 and a sealing assembly 300, wherein the refrigerating unit 131 is located at the front end of the split type thermal insulation container, and can perform refrigeration in the split type thermal insulation container during operation, so that the interior of the container is kept at a proper refrigeration temperature, and further, damage to temperature-sensitive equipment caused by inconsistent temperature conditions is prevented. The sealing assembly 300 is disposed between the inner peripheral side surface of the bottom of the case 100 and the outer peripheral side surface of the floor 211 to fill the gap between the case 100 and the floor 211, compared with the case where the sealing assembly 300 is disposed between the upper surface of the floor 211 and the bottom of the case 100, the sealing assembly 300 can reduce the influence on the sealing performance due to the different loads at different positions on the floor 211, which may result in the flatness of the upper surface of the floor 211 due to the different loads at different positions on the floor 211, thereby resulting in poor local sealing performance.

In addition, referring to fig. 3 and 4, the bottom inner circumferential side of the case 100 is further provided with grooves, which are continuously provided in the circumferential direction of the case 100, and which extend downward to the lower surface of the case 100. The seal assembly 300 includes a first seal body 310 and a second seal body 320. The first sealing body 310 is of a sheet structure matched with the groove, the first sealing body 310 is arranged in the groove, the height of the first sealing body 310 along the vertical direction is the same as the width of the groove, and the width direction of the groove is consistent with the vertical direction. The second sealing body 320 is continuously provided on the outer circumferential side surface of the floor panel 211 in the circumferential direction of the floor panel 211. One or both of the first sealing body 310 and the second sealing body 320 are made of soft elastic materials, and the second sealing body 320 forms extrusion sealing fit with the first sealing body 310 after the box body 100 is buckled with the bottom plate. In this embodiment, since the groove extends downward to the lower surface of the case 100, it is possible to facilitate the first sealing body 310 to be also extended to the lower edge of the case 100, thereby facilitating the reliable contact of the first sealing body 310 with the second sealing body 320, and thus ensuring sealability; one or both of the first sealing body 310 and the second sealing body 320 are made of soft elastic materials, and the soft elastic materials are easier to generate adaptive deformation due to different hard structures, so that the contact area between the first sealing body 310 and the second sealing body 320 is increased, and the sealing effect is improved.

Under the condition that the first sealing body 310 and the second sealing body 320 are made of soft elastic materials, since the case 100 and the floor 211 are often required to be disassembled along the vertical direction, in the disassembling process, the first sealing body 310 and the second sealing body 320 deform due to relative sliding, so that not only is the damping increased, but also the service lives of the first sealing body 310 and the second sealing body 320 are shortened. In this regard, referring to fig. 3, the first sealing body 310 of the present invention is constructed as a plate made of hard material, and the second sealing body 320 is made of soft elastic material; the second sealing body 320 is composed of a connection portion 321 and a blocking sealing strip 322, the connection portion 321 is connected to an outer circumferential side of the floor 211 and is continuously provided along a circumferential direction of the floor 211, the blocking sealing strip 322 is connected to the connection portion 321 and is continuously provided along a distribution locus of the connection portion 321, a sectional shape of the blocking sealing strip 322 is configured as a bar, the bar is arranged in a lateral shape, and a sectional length of the blocking sealing strip 322 is greater than a lateral gap between a bottom inner circumferential side of the case 100 and the outer circumferential side of the floor 211. By adopting the plate made of hard material for the first sealing body 310 and adopting the soft elastic material for the second sealing body 320, damping can be reduced, and smoothness of the first sealing body 310 and the second sealing body 320 during relative sliding can be increased, so that the disassembly and assembly of the box body 100 and the bottom plate 200 are facilitated. By constructing the second sealing body 320 to be composed of the connecting portion 321 and the blocking sealing strip 322, particularly, the blocking sealing strip 322 has a transverse bar shape, and a transverse length thereof is greater than a transverse gap between the case 100 and the floor 211, when in use, a free end (an end far from the connecting portion 321) of the blocking sealing strip 322 can be abutted against the first sealing body 310 and deformed by transverse extrusion, thereby achieving a reliable sealing effect.

Referring to fig. 3 and 4, the blocking sealing strips 322 may be arranged at intervals along the vertical direction, so that a plurality of seals may be formed, and a more reliable effect of blocking heat exchange between the inside and the outside of the box is achieved.

Since the case 100 is a case structure having an opening at the bottom, the width of deformation or movement of the case walls around the case 100 in the lateral direction gradually increases from top to bottom when in use. In this regard, in order to ensure the stability and reliability of the sealing performance of the second sealing body 320 and the first sealing body 310 in the vertical direction, the cross-sectional length of each of the barrier sealing strips 322 of the present invention increases from top to bottom, referring to fig. 3 to 4.

The first sealing body 310 may be made of a self-lubricating material, so that resistance between the case 100 and the bottom plate 200 is reduced in the process of combining the case 100 and the bottom plate 200, and the case that the case 100 and the bottom plate 200 are not assembled in place is prevented, and abrasion to the second sealing body 320 is not generated when the case 100 and the bottom plate 200 have relative displacement or vibration. The second sealing body 320 adopts a plurality of layers of blocking sealing strips 322 from top to bottom, and the length of the blocking sealing strip 322 at the lowest layer is longest, so that at least one layer of sealing strip is tightly attached to the first sealing body 310, and the sealing reliability is improved. Furthermore, when the container body is in a cargo state, the bottom plate 200 may generate downward elastic deformation under the action of the cargo weight, and the multi-layer blocking sealing strip 322 may still ensure effective contact with the first sealing body 310 under the condition that the bottom plate 200 is deformed downward, so as to ensure that the container is always airtight and has a good heat insulation layer, effectively isolate the internal and external circulation of air, and simultaneously the sealing element may be made of good heat insulation materials such as rubber, so as to avoid the generation of a thermal bridge, so that the combined container has good airtight performance and heat insulation performance.

When the bottom plate 200 is loaded with the cargo, in order to prevent interference between the first sealing body 310 and the cargo during lifting and falling of the container body 100, the surface of the first sealing body 310 facing the inside of the container may not protrude beyond the inner wall elevation of the container.

In a transportation state, a base or a tray is usually installed at the bottom of an apparatus, etc., and in a case of carrying goods in a container, if the goods are laterally displaced during transportation, or in a case of lifting and falling the container 100, collision or friction between the tray of the goods and the inner wall of the container 100 may occur. In order to solve this problem, the present invention adopts the first sealing body 310 made of non-metallic material such as polymer material, and extends the first sealing body 310 upward above the floor 211, and the height of the extending portion of the first sealing body 310 may be greater than or equal to the normal height of the cargo pallet, referring to fig. 3 and 4. When the first sealing body 310 is made of a non-metal material such as a polymer material, it needs to meet the strength requirement of anti-collision, so as to prevent the side plate 120 from being deformed or damaged when being impacted, and once the side plate 120 is deformed or damaged, the sealing and heat-insulating performance of the container may be affected.

In order to reinforce the bottom edge of the case 100 and prevent the peripheral side walls from being displaced or deformed outside the case, the present invention is preferably configured such that reinforcing beams 160 are continuously provided on the bottom peripheral side surface of the case 100 in the circumferential direction, the reinforcing beams 160 are made of steel plates, and are specifically configured to cover the bottom lower edge of the case 100, referring to fig. 3 and 4.

Referring to fig. 3 and 4, the peripheral side walls of the case 100 are each of a sandwich structure, and the walls include a side plate 120, a top plate 110, a front end plate, and a door 141, and the construction of the walls will be explained below using the side plate 120 as an example.

The side plate 120 is a sandwich structure, and the side plate 120 includes an outer wrapping layer and an inner insulation layer 123 from the sectional view of fig. 4, where the wrapping layer includes an outer skin 121, a reinforcing beam 160, a first sealing body 310, and an inner skin 122 that are sequentially connected. The outer skin 121 is attached to the side of the insulation layer 123 facing the outside of the box, and the lower edge of the outer skin 121 is arranged apart from the lower edge of the insulation layer 123, i.e. the lower edge of the outer skin 121 does not extend to the lower edge of the insulation layer 123. The inner skin 122 is attached to a side of the side plate 120 facing the inside of the case, the lower edge of the inner skin 122 is disposed apart from the lower edge of the insulation layer 123, i.e., the lower edge of the inner skin 122 does not extend to the lower edge of the insulation layer 123, and in the assembled state of the case 100 and the bottom plate 200, the lower edge of the inner skin 122 is disposed at a distance from the upper surface of the floor 211, i.e., the lower edge of the inner skin 122 is located at a position above the upper surface of the floor 211. The stiffening beam 160 is formed by bending a metal plate, one end of the stiffening beam 160 is located outside the heat insulation layer 123 and is connected with the lower edge of the outer side skin 121, the other end of the stiffening beam 160 is arranged on the inner side of heat insulation in a leaning manner and is arranged in a separated manner with the lower edge of the inner side skin 122, and the middle of the stiffening beam 160 is wrapped on the outer surface of the lower edge of the heat insulation layer 123. The first sealing body 310 is constructed as a plate made of a nonmetallic material into a shape, the first sealing body 310 is disposed between the lower edge of the inside skin 122 and the other end of the reinforcement beam 160, specifically, the upper edge of the first sealing body 310 is sealingly connected with the lower edge of the inside skin 122, and the lower edge of the first sealing body 310 is sealingly connected with the other end of the reinforcement beam 160. It will be appreciated by those skilled in the art that in order to block heat exchange between the inside and the outside of the case 100 to avoid formation of a thermal bridge, it is preferable that the lower edge of the inside skin 122 is spaced apart from the other end of the reinforcement beam 160, and the lower edge of the inside skin 122 is connected to the other end of the reinforcement beam 160 using a first sealing body 310 made of a non-metal material. In order to prevent the tray or the base of the cargo in the box from damaging or deforming the side plate 120 due to collision with the lower inner side surface of the side plate 120, the first sealing body 310 may be made of a material having a certain hardness and strength, and if necessary, the first sealing body 310 may be thicker, for example, the thickness of the first sealing body 310 may be greater than the thickness of the inner skin 122.

Wherein, the outer skin 121, the inner skin 122 and the reinforcement beam 160 are all made of metal, and the first sealing body 310 is preferably a plate made of a polymer material meeting the corresponding rigidity and strength requirements. This can not only secure the strength of the outer skeleton of the side plate 120, but also prevent the side plate 120 from forming a thermal bridge, and can function to prevent the cargo pallet or the base from directly striking the side plate 120 by using the first sealing body 310.

In some cases, if the inner skin 122 is made of a non-metal material, the first sealing body 310 may be optionally made into a whole with the inner skin 122, so that the purpose of blocking the formation of a thermal bridge may be achieved, but the thickness of the skin is usually smaller, so that the lower end of the inner skin 122 is thickened to meet the anti-collision performance, which obviously is inconvenient to manufacture, and also affects the overall strength of the inner skin.

Referring to fig. 1 to 3, the circumferential outer contour of the floor 211 is within the circumferential outer contour of the body 210, and the outer circumferential edge of the body 210 is detachably connected with the lower edge of the case 100. So that the connection structure between the cabinet 100 and the bottom plate 200 does not occupy the space in the cabinet.

In order to guide and position the case 100 during the downward movement of the case 100 to be coupled with the bottom plate 200. Referring to fig. 1 to 5, in a further preferred embodiment of the present invention, guide stoppers 212 are provided on a body 210 of a base plate 200, the guide stoppers 212 are respectively disposed at both ends in a length direction and/or both ends in a width direction of the body 210, and may be provided around the base plate 200, guide slopes 2121 for guiding downward movement of a case 100 are provided at inner sides of upper ends of the guide stoppers 212, the guide slopes 2121 are configured to be inclined to a height direction of the case 100 and face an inside of the case 100, and inner sides of lower ends of the guide stoppers 212 are abutted to outer side walls of the case 100 after the case 100 and the base plate are assembled to position the case 100.

The lower edge of the container 100 is limited in a fixed area during the transportation process of the assembled container with the assembled container body 100 and the assembled container with the bottom plate 200, so that the first sealing body 310 and the second sealing body 320 are tightly attached to each other in a combined state, the circumferential sealing consistency of the container body is further ensured, and the sealing effect is further improved.

More preferably, referring to fig. 3 to 5, a guiding and limiting groove 170 is provided on the bottom peripheral side of the case 100, the guiding and limiting groove 170 can form an insertion fit with the guiding and limiting block 212, and the outer vertical surface of the guiding and limiting block 212 does not exceed the outer vertical surface of the case 100, in other words, the lateral outer contour of the guiding and limiting block 212 is completely located inside the guiding and limiting groove 170.

Referring to fig. 4, a chamfer 2112 is provided at an edge portion of an upper surface of the floor 211, and the chamfer 2112 can reduce interference between the floor 211 and the box 100 in a downward assembly process of the box 100, and is beneficial to guiding downward movement of the box 100 to the bottom plate 200, so that accurate positioning of the box 100 in a horizontal direction is ensured, and rapid and accurate butt joint of the box 100 and the bottom plate 200 is facilitated. The floor 211 is provided at a peripheral side thereof with a receiving groove 2111, the receiving groove 2111 is fitted with the second sealing body 320, specifically, the connecting portion 321 is fitted in the receiving groove 2111, and the blocking seal 322 is extended to the outside of the floor 211 in the horizontal direction. The connection portion 321 may be a sheet-like structure, and the thickness of the connection portion 321 in the sheet-like shape is smaller than the depth of the accommodation groove 2111 in the horizontal direction.

Referring to fig. 1,2, 5 and 6, first connectors 150 are respectively disposed at corners of the bottom of the case 100, and second connectors 220 capable of forming a detachable locking connection with the first connectors 150 are respectively disposed at corners of the body 210. The first connecting piece 150 has a locking opening 151, the second connecting piece 220 has a locking head 221 which can form locking connection with the locking opening 151, the locking head 221 and the locking opening 151 are matched with each other to form a locking connection assembly, and the locking connection assembly can be implemented by adopting the existing structure when being implemented.

For example, referring to fig. 1, 5 and 6, the second link 220 has a locking base mounted on the base plate 200, and a locking head 221 rotatably coupled to the locking base, the locking head 221 is coupled with a handle 222 operable thereto, the first link 150 is constructed with a waist-shaped hole as the locking notch 151, and the posture of the locking head 221 is rotated to be consistent with the waist-shaped hole, that is, the length direction of the locking head 221 is consistent with the length direction of the waist-shaped hole, before the case 100 is assembled to the base plate 200, thereby allowing the locking head 221 to be inserted into the waist-shaped hole during the placement of the case 100 on the base plate 200. Then, the handle 222 is rotated to drive the lock head 221 to rotate in the waist-shaped hole until the length direction of the lock head 221 is intersected with the length direction of the waist-shaped hole (can be vertical), the length of the lock head 221 is larger than the width of the waist-shaped hole, and the width of the lock head 221 is slightly smaller than the aperture of the waist-shaped hole, so that a convenient and quick locking function is realized, and finally, the handle 222 is locked on the box body, so that the lock head 221 is prevented from being invalid due to vibration rotation in the transportation process.

The application method of the split type heat preservation container comprises the following steps: before loading cargoes, the box body 100 is lifted from the bottom plate 200, and the specific lifting parts can be corner pieces at four corners of the top plate 110 or lifting pieces additionally arranged on the top plate 110; then loading onto base plate 200 or unloading from base plate 200; after the loading/unloading operation is completed, the container body 100 is lifted onto the bottom plate 200, and the container body 100 and the bottom plate 200 are locked and fixed by the first connecting piece 150 and the second connecting piece 220, so that a complete container can be formed.

The polyurethane foaming heat-insulating layers are arranged on the inner walls of the box body 100 and the upper part of the floor 211, and the sealing and heat-insulating performances of the container are guaranteed by providing a good sealing structure, and an operator can conveniently and efficiently connect the box body 100 and the bottom plate 200 into a sealed and firm container by adopting a simple and reliable connecting structure; in the case of the refrigerator group 131, the container can be used as a container with heat preservation/refrigeration function; in addition, after the case 100 is removed from the base 200, loading and unloading of large-sized goods can be facilitated, thereby reducing the probability of damage to goods due to insufficient operating space for loading and unloading.
