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 specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

The invention provides a split type heat preservation container, and referring to fig. 1 to 6, the appearance of the split type heat preservation container is a cuboid, the inner wall of the split type heat preservation container is provided with a heat preservation layer, and the split type heat preservation container comprises a container body 100 and a bottom plate 200. The cabinet 100 is configured as a cabinet having an open 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 base plate 200 is detachably coupled to a bottom opening of the cabinet 100, the base plate 200 includes a body 210 and a floor 211 upwardly protruded from the body 210, and in a state where the cabinet 100 is coupled to the base plate 200, the floor 211 is protruded into the bottom opening and an outer circumferential side surface of the floor 211 is sealingly engaged with an inner circumferential side surface of a bottom of the cabinet 100.

The split type heat-insulation container is formed by separably combining the container body 100 and the bottom plate 200, and after the container 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 is improved, and the goods damage caused by collision is prevented; the container body is rectangular, so that the container not only meets the transportation requirement, but also is beneficial to providing a larger accommodating space for equipment such as instruments to be transported in the container; the heat-insulating layer is arranged on the inner wall of the container, so that proper heat-insulating conditions are provided for equipment such as instruments in the container, particularly the transportation of equipment sensitive to temperature is facilitated, and further the cargo damage caused by inconsistent temperature conditions is prevented; by arranging the sealing assembly 300 between the bottom inner peripheral side surface of the box body 100 and the outer peripheral side surface of the floor 211, the transverse gap at the joint of the box body 100 and the bottom plate is filled, so that the temperature exchange between the inside and the outside of the container is blocked, the heat insulation performance of the container is further improved, and when the load of the bottom plate 200 in the length direction is different, the sealing consistency and the sealing effect between the bottom plate 200 and the box body 100 in the length direction of the box body can be still ensured.

When the split type heat-insulation container is used for transporting equipment sensitive to temperature conditions, only the heat-insulation effect is insufficient, and refrigeration and better sealing and cold insulation functions are often needed. In view of the above, referring to fig. 1, 2 and 5, the split thermal container of the present invention further includes a refrigeration unit 131 and a sealing assembly 300, wherein the refrigeration unit 131 is located at the front end of the split thermal container, and is operable to refrigerate the interior of the split thermal container, so that the interior of the container is maintained at a proper refrigeration temperature, thereby preventing damage to the temperature-sensitive equipment due to non-compliance with the temperature conditions. The sealing assembly 300 is disposed between the inner peripheral side of the bottom of the box body 100 and the outer peripheral side of the floor 211 to fill a gap at the junction of the box body 100 and the floor 211, and compared to the sealing assembly 300 disposed between the upper surface of the floor 211 and the bottom of the box body 100, the sealing assembly can reduce the influence on the sealing performance due to different loads at different positions on the floor 211, because the different loads at different positions on the floor 211 can cause the flatness of the upper surface of the floor 211, thereby causing the local sealing performance to be poor.

In addition, referring to fig. 3 and 4, the bottom inner peripheral side surface of the casing 100 is further provided with a groove, which is continuously provided along the circumferential direction of the casing 100 and extends downward to the lower surface of the casing 100. The seal assembly 300 includes a first sealing body 310 and a second sealing body 320. The first sealing body 310 is a sheet structure adapted to the groove, the first sealing body 310 is installed in the groove, the height of the first sealing body 310 in the vertical direction is the same as the width of the groove, and the width of the groove is the same as the vertical direction. The second sealing body 320 is provided continuously along the circumferential direction of the floor panel 211 on the outer circumferential side surface 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 material, and the second sealing body 320 is in extrusion sealing fit with the first sealing body 310 after the box body 100 and the bottom plate are buckled. In this embodiment, since the groove extends downward to the lower surface of the box 100, it can be beneficial to extend and arrange the first sealing body 310 to the lower edge of the box 100, so as to facilitate the reliable contact between the first sealing body 310 and the second sealing body 320, and further ensure the sealing performance; one or both of the first sealing body 310 and the second sealing body 320 are made of soft elastic material, because the soft elastic material is more easily deformed adaptively due to different hard structures, which is beneficial to increase the contact area between the first sealing body 310 and the second sealing body 320, and further improves the sealing effect.

In the case where the first sealing body 310 and the second sealing body 320 are both made of a soft elastic material, since the case 100 and the floor 211 are often detached in the vertical direction, the first sealing body 310 and the second sealing body 320 are deformed by relative sliding during the detachment, so that not only is the damping increased, but also the life of the first sealing body 310 and the second sealing body 320 is shortened in the past. In this regard, referring to FIG. 3, the first sealing body 310 of the present invention is constructed as a plate made of a hard material, and the second sealing body 320 is made of a 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 the outer circumferential side of the floor 211 and continuously provided along the circumferential direction of the floor 211, the blocking sealing strip 322 is connected to the connection portion 321 and continuously provided along the distribution locus of the connection portion 321, the cross-sectional shape of the blocking sealing strip 322 is configured in a strip shape, the strip shape is arranged in a transverse shape, and the cross-sectional length of the blocking sealing strip 322 is greater than the transverse gap between the bottom inner circumferential side of the cabinet 100 and the outer circumferential side of the floor 211. By making the first sealing body 310 of a plate made of a hard material and the second sealing body 320 of a soft elastic material, damping can be reduced, and smoothness of the first sealing body 310 and the second sealing body 320 during relative sliding can be increased, thereby facilitating the disassembly and assembly of the box body 100 and the bottom plate 200. By configuring the second sealing body 320 to be composed of the connecting portion 321 and the blocking sealing strip 322, particularly, the cross-sectional shape of the blocking sealing strip 322 is a transverse strip shape, and the transverse length of the blocking sealing strip 322 is greater than the transverse gap between the box body 100 and the floor 211, so that when in use, the free end (the end far away from the connecting portion 321) of the blocking sealing strip 322 can be abutted and contacted with the first sealing body 310 and can deform due to transverse extrusion, and a reliable sealing effect is achieved.

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

Since the box 100 is a box structure with an opening at the bottom, the deformation or movement of the walls of the box 100 in the transverse direction gradually increases from top to bottom when the box is 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 at all points in the vertical direction, the length of the cross section of each of the barrier sealing strips 322 of the present invention is increased from the top down, see fig. 3 to 4.

The first sealing body 310 may be made of a self-lubricating material, so that in the process of combining the case 100 and the bottom plate 200, the resistance between the case 100 and the bottom plate 200 is reduced, the case that the case 100 and the bottom plate 200 are not assembled in place is prevented, and the second sealing body 320 is not abraded 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 barrier sealing strips 322 from top to bottom, and the length of the barrier sealing strip 322 at the lowest layer is the longest, so that at least one layer of the second sealing body is tightly attached to the first sealing body 310, and the sealing reliability is improved. Furthermore, when the container body is in a cargo carrying state, the bottom plate 200 can generate downward elastic deformation under the action of the weight of the cargo, the multilayer blocking sealing strip 322 can still ensure the effective contact with the first sealing body 310 under the condition that the bottom plate 200 deforms downward, the container is ensured to be always a closed space with a good heat insulation layer, the inside and outside circulation of air is effectively isolated, meanwhile, the sealing element can be made of good heat insulation materials such as rubber and the like, so that the generation of a heat bridge is avoided, and the combined container has good air tightness and heat insulation performance.

In order to prevent interference between the first sealing body 310 and the cargo during the lifting and dropping of the container body 100 when the cargo is loaded on the bottom plate 200, the surface of the first sealing body 310 facing the inside of the container of the present invention may not exceed the inner wall elevation of the container.

In a transportation state, a base or a tray is usually installed at the bottom of equipment such as an instrument, and when a cargo is loaded in a container, if the cargo is laterally displaced in the transportation process, or the tray of the cargo may collide or rub against the inner wall of the container 100 in the lifting and dropping process of the container 100. To solve this problem, the present invention uses the first sealing body 310 made of non-metal material such as polymer material, and extends the first sealing body 310 upwards to the upper side of the floor 211, and the height of the extended portion of the first sealing body 310 may be greater than or equal to the normal height of the cargo pallet, see fig. 3 and 4. When the first sealing body 310 made of non-metallic materials such as high polymer materials is used, the requirement for collision-proof strength is required to be met, so that the side plate 120 is prevented from deforming or being damaged when being impacted, and once the side plate 120 deforms or is damaged, the sealing and heat-insulating performance of the container can be possibly affected.

In order to reinforce the bottom edge of the box 100 and prevent the peripheral side walls from displacing or deforming outside the box, a preferred embodiment of the present invention is to continuously provide a reinforcement beam 160 on the bottom peripheral side of the box 100 along the circumferential direction, wherein the reinforcement beam 160 is made of steel plate and is specifically configured as a hem for the bottom lower edge of the box 100, referring to fig. 3 and 4.

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

The side panel 120 is of a sandwich structure, and as seen in the sectional view of fig. 4, the side panel 120 includes a wrapping layer located at the outside and an insulation layer 123 located at the inside, wherein the wrapping layer includes an outer skin 121, a reinforcing beam 160, a first sealing body 310, and an inner skin 122, which are connected in sequence. The outer skin 121 is attached to the side of the insulation layer 123 facing the outside of the tank, and the lower edge of the outer skin 121 is arranged separately 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 the side of the side panel 120 facing into the tank, the lower edge of the inner skin 122 is disposed apart from the lower edge of the insulating layer 123, i.e., the lower edge of the inner skin 122 does not extend to the lower edge of the insulating layer 123, and in the state where the tank body 100 is assembled with the floor panel 200, the lower edge of the inner skin 122 is disposed at a distance from the upper surface of the floor panel 211, i.e., the lower edge of the inner skin 122 is located at a position above the upper surface of the floor panel 211. The reinforcing beam 160 is formed by bending a metal plate, one end of the reinforcing 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 reinforcing beam 160 is arranged on the inner side of the heat insulation layer in an abutting mode and is arranged separately from the lower edge of the inner side skin 122, and the middle of the reinforcing beam 160 is wrapped on the outer surface of the lower edge of the heat insulation layer 123. The first sealing body 310 is configured as a plate made of a non-metallic material in a solid shape, and the first sealing body 310 is disposed between the lower edge of the inner skin 122 and the other end of the reinforcement beam 160, specifically, the upper edge of the first sealing body 310 is sealingly connected to the lower edge of the inner skin 122, and the lower edge of the first sealing body 310 is sealingly connected to 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 outside of the tank body 100 to avoid the formation of a thermal bridge, it is preferable to space the lower edge of the inner skin 122 from the other end of the reinforcement beam 160 and to connect the lower edge of the inner skin 122 to the other end of the reinforcement beam 160 with the first sealing body 310 made of a non-metallic material. In order to prevent the tray or the base of the goods in the box from being damaged or deformed by the collision with the inner side of the lower end of the side panel 120, the first sealing body 310 may be made of a material having 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 that of the inner skin 122.

The outer skin 121, the inner skin 122, and the reinforcing beam 160 are made of metal, and the first sealing body 310 is preferably a plate made of a polymer material that satisfies the corresponding rigidity and strength requirements. Thus, the strength of the external skeleton of the side plate 120 can be ensured, the side plate 120 can be prevented from forming a thermal bridge, and the first sealing body 310 can be used for preventing the goods tray or the base from directly impacting the side plate 120.

In some cases, if the inner skin 122 is made of a non-metal material, the first sealing body 310 may be made integrally with the inner skin 122, so that although the purpose of blocking the formation of the thermal bridge may also be achieved, the skin is generally smaller in thickness, and is made thicker for the lower end in order to meet the impact-proof performance of the lower end of the inner skin 122, which is obviously inconvenient to make, and may also have an effect on 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 peripheral edge of the body 210 is detachably connected to the lower edge of the box 100. So that the coupling structure between the cabinet 100 and the base plate 200 does not occupy the space inside the cabinet.

In order to guide and position the casing 100 during the process of moving the casing 100 down to be coupled with the base plate 200. Referring to fig. 1 to 5, in a further preferred embodiment of the present invention, the body 210 of the base plate 200 is provided with guide stoppers 212, the guide stoppers 212 are respectively disposed at two ends of the body 210 in the length direction and/or two ends of the body in the width direction, the guide stoppers 212 may be respectively disposed around the base plate 200, the inner side of the upper end of the guide stopper 212 has a guide inclined surface 2121 for guiding the downward movement of the box 100, the guide inclined surface 2121 is configured to be inclined to the height direction of the box 100 and face the inside of the box 100, and the inner side of the lower end of the guide stopper 212 abuts against the outer side wall of the box 100 after the box 100 and the base plate are assembled to position the box 100.

In the transportation process of the assembled container of the box body 100 and the bottom plate 200 and the assembled container, the lower edge of the box body 100 is limited in a fixed area, 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 box body is further ensured, and the sealing effect is further improved.

More preferably, referring to fig. 3 to 5, a guide limiting groove 170 is disposed on a side surface of the bottom periphery of the box 100, the guide limiting groove 170 can form an insertion fit with the guide limiting block 212, an outer vertical surface of the guide limiting block 212 does not exceed the outer vertical surface of the box 100, in other words, a lateral outer contour of the guide limiting block 212 is completely located within the guide limiting groove 170.

Referring to fig. 4, the edge of the upper surface of the floor 211 is provided with a chamfer 2112, and the chamfer 2112 can reduce the interference between the floor 211 and the box 100 during the downward assembly of the box 100, and is beneficial to the downward movement of the box 100 towards the bottom plate 200 for guiding, so as to ensure the accurate positioning of the box 100 along the horizontal direction, thereby being beneficial to the rapid and accurate butt joint of the box 100 and the bottom plate 200. The peripheral side of the floor 211 is provided with a receiving groove 2111, the receiving groove 2111 is assembled with the second sealing body 320, specifically, the connecting portion 321 is assembled in the receiving groove 2111, and the blocking sealing strip 322 extends to the outside of the floor 211 along the horizontal direction. The connecting portion 321 may be a sheet-shaped structure, and the thickness of the sheet-shaped connecting portion 321 is smaller than the depth of the accommodating groove 2111 in the horizontal direction.

Referring to fig. 1, 2, 5 and 6, a first connector 150 is respectively disposed at each corner of the bottom of the box 100, and a second connector 220 capable of forming a detachable locking connection with the first connector 150 is respectively disposed at each corner of the body 210. The first connecting member 150 has a locking opening 151, the second connecting member 220 has a locking head 221 capable of forming a locking connection with the locking opening 151, the locking head 221 and the locking opening 151 cooperate with each other to form a locking connection assembly, and the locking connection assembly can be implemented by adopting an existing structure in specific implementation.

For example, referring to fig. 1, 5 and 6, the second link 220 has a lock seat installed on the base plate 200, and a locking head 221 rotatably connected to the lock seat, the locking head 221 is connected with a handle 222 for operation, the first link 150 is configured with a kidney-shaped hole as a locking opening 151, and before the box body 100 is assembled to the base plate 200, the locking head 221 is rotated to be in conformity with the kidney-shaped hole, that is, the length direction of the locking head 221 is in conformity with the length direction of the kidney-shaped hole, thereby allowing the locking head 221 to be inserted into the kidney-shaped hole during the placement of the box body 100 on the base plate 200.
