Description

Technical Field

[0001] This utility model relates generally to the technical field of container structures, and more specifically to a cold storage and heat insulation container. Background Technology

[0002] Insulated containers are used to transport goods with specific temperature requirements, such as perishable foods and pharmaceuticals, while maintaining them within a certain temperature range. They can be transported by sea, road, or rail, providing door-to-door delivery services within a specific timeframe. To precisely control the temperature inside the insulated container and extend transport time, common methods include building in-house refrigeration / cooling units (mechanical refrigerated containers, also known as active refrigeration) or placing cold storage plates inside the container (cold storage insulated containers, also known as passive refrigeration). These cold storage plates are filled with phase change materials that can store cold energy.

[0003] In actual operation, insulated containers with cold storage systems transport various goods, each with different temperature control requirements. Some goods may be frozen (requiring a temperature no higher than -18°C) or chilled (requiring a temperature around 0°C). Furthermore, for chilled goods around 0°C, different types of vegetables and fruits generate varying amounts of respiration heat, requiring different amounts of cooling capacity to maintain the container's temperature. The cold storage plates consist of an outer packaging and an internal phase change material. The cold storage process involves the phase change material changing from liquid to solid, similar to water turning into ice. Each cold storage plate increases in volume after storing cold. For example, if dozens of cold storage plates are installed inside a 40-foot insulated container, the overall installation dimensions will change significantly before and after the phase change, necessitating solutions for the installation and securing of the cold storage plates.

[0004] Therefore, there is a need to provide a cold storage insulated container to at least partially solve the above problems. Utility Model Content

[0085] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0086] This utility model provides a cold storage insulated container.

[0087] Please see Figures 1 to 3 The container 100 includes a container body 110 and a fastening member 131. The fastening member 131 is located inside the container body 110. The fastening member 131 is adjustably connected to the container body 110 along a first direction between a first position and a second position. Specifically, please refer to... Figure 4 The fixing member 131 includes an abutment portion 133, which is spaced from the inner wall of the housing 110 along a first direction to define the position of the cold storage assembly 120 along the first direction. It should be noted that, along the first direction, the second position is closer to the inner wall than the first position. The abutment portion 133 at the first position defines the position of the cold storage assembly 120 in the cold storage state, and the abutment portion 133 at the second position defines the position of the cold storage assembly 120 in the cold release state.

[0088] According to the present invention, the cold storage insulated container 100 can fix the cold storage component 120 in the cold storage state and the cold release state by fixing the fixing component 131 and the inner wall of the container body 110, so that the same cold storage insulated container 100 can meet the requirements of transporting frozen goods or goods requiring different cold capacity by replacing the cold storage component 120 in different states.

[0089] Furthermore, Figure 2 In the middle, the cold storage component 120 is in the cold storage state, and the fixed component 131 is located in the first position. Figure 3 In this configuration, the cold storage component 120 is in a cold release state, and the fixing member 131 is in a second position. That is, the cold storage component 120 has switchable cold storage and cold release states. Specifically, when the cold storage component 120 is connected to the housing 110 and is in the cold storage state, the fixing member 131 is in the first position; when the cold storage component 120 is connected to the housing 110 and is in the cold release state, the fixing member 131 is in the second position.

[0090] It is understood that the cold storage component 120 can be integrated into the interior of the container 110 or it can be an externally purchased component. Preferably, the container 100 includes the cold storage component 120. The cold storage component 120 is located inside the container 110 and is movably connected to the container 110 along a first direction. When the cold storage component 120 is connected to the container 110, along the first direction, the cold storage component 120 has a first end 124 abutting against the inner wall and a second end 125 away from the inner wall, and the abutting portion 133 abuts against the second end 125 or is spaced apart from the second end 125 along the first direction.

[0091] Return to reference Figure 1 As those skilled in the art will know, the enclosure 110 includes a top plate 111, a base frame 112, a front end 113, a door end 114, and a side plate 115. At least one of the top plate 111, base frame 112, front end 113, door end 114, and side plate 115 is used to mount the cold storage assembly 120. For example Figure 2 and Figure 3 In this configuration, the cold storage component 120 is located at the side panel 115; correspondingly, the aforementioned first direction configuration is the length direction DL of the container 100. In an embodiment not shown, the cold storage component 120 may also be located at at least one of the top panel 111, the base frame 112, the front end 113, and the door end 114; correspondingly, the first direction may also be the width direction DW and / or the height direction DH of the container 100. To improve the thermal insulation effect of the container 100, a radiative cooling coating 116 may also be provided on the outer surface of the container body 110.

[0092] Please see Figures 2 to 4 The container 100 also includes a securing device 130. Specifically, the securing device 130 includes the aforementioned securing member 131 and a guide limiting assembly 150, the guide limiting assembly 150 being connected to the securing member 131 and the container body 110. Further, the securing member 131 has an adjustment hole 134 extending along a first direction (e.g., the length direction DL of the container 100). The guide limiting assembly 150 includes a guide member 151, the guide member 151 being partially connected to the adjustment hole 134 and detachably connected to the container body 110. See also... Figure 4 The fixing member 131 also includes a connecting portion 132, which is detachably connected to the housing 110. The connecting portion 132 has the aforementioned adjusting hole 134, which extends through the connecting portion 132 along its thickness direction. The connecting portion 132 is inclined or perpendicular to the abutment portion 133. For example... Figure 4 In this case, the connecting part 132 is perpendicular to the abutting part 133. In other words, the cross-sectional structure of the fixing member 131 is L-shaped, for example, the fixing member 131 is made of L-shaped angle steel.

[0093] Please continue reading. Figure 2 and Figure 4 To improve the stability of the connection between the fixing member 131 and the housing 110, preferably, the number of adjustment holes 134 in a single fixing member 131 is at least two, and the at least two adjustment holes 134 are spaced apart along a second direction, which is perpendicular to the first direction. For example Figure 2 and Figure 3 In this design, each fixing member 131 has two adjustment holes 134, configured in the length direction DL of the container 100 and in the height direction DH of the container 100. It should be noted that the number of guide members 151 is the same as the number of adjustment holes 134, and the guide members 151 are connected to their respective adjustment holes 134.

[0094] Specifically, please refer to Figure 4 The guide member 151 includes a guide portion 152 and a limiting portion 153. The guide portion 152 extends into the adjustment hole 134, and its outer peripheral surface is at least partially located inside the adjustment hole 134. The limiting portion 153 is located outside the adjustment hole 134 and connected to the guide portion 152. The outer peripheral surface of the limiting portion 153 protrudes at least partially outward from the adjustment hole 134. The limiting portion 153 is used to cooperate with the housing 110 so that the fixing member 131 is restricted between the limiting portion 153 and the housing 110. For example... Figure 4 In this assembly, the guide member 151 is constructed in a stepped cylindrical shape; in other words, the guide member 151 has a mounting hole extending through it along its axial direction. Furthermore, the guide limiting assembly 150 also includes a bolt 154, a spring washer 155, a flat washer 156, and a nut 157. Specifically, the nut 157 is embedded in the side plate 115, for example, as part of the insulation layer inside the side plate 115. The spring washer 155 and the flat washer 156 pass through the bolt 154; it can be understood that along the axial direction of the bolt 154, the spring washer 155 is closer to the head of the bolt 154 than the flat washer 156. The bolt 154 is then passed through the mounting hole of the guide member 151 and extends outwards to connect to the nut 157, thereby connecting the fixing member 131 to the housing 110. Through the cooperation of the adjusting hole 134 and the guide portion 152, the fixing member 131 can be adjusted by moving between a first position and a second position along a first direction.

[0095] Return to reference Figure 2 and Figure 3When the cold storage component 120 is connected to the container 110, its position needs to be fixed during use; in other words, the fixing member 131 needs to be held in a first position or a second position. Therefore, the fixing device 130 also includes an assembly assembly 140, which is connected to the container 110 and the fixing member 131. The assembly assembly 140 is used to hold the fixing member 131 in the first position or the second position. Specifically, the assembly assembly 140 includes a spring pin 141, a first mounting base 142, and a second mounting base 143. The first mounting base 142 is connected to the fixing member 131, and the second mounting base 143 is connected to the container 110. The spring pin 141 is adjustablely connected to the first mounting base 142 along the height direction DH of the container 100, so that the spring pin 141 is switchably connected to the second mounting base 143 between a locked position and an unlocked position. For example... Figure 2 and Figure 3 In this assembly, the assembly components 140 are located at the top and bottom of the fixing member 131. There are two sets of assembly components 140, which are spaced apart along a first direction. One set of assembly components 140 is used to hold the fixing member 131 in a first position, and the other set of assembly components 140 is used to hold the fixing member 131 in a second position.

[0096] Please see Figure 5 and Figure 6 The container 100 also includes a track assembly 160, which is located inside and connected to the container body 110. The track assembly 160 is used to connect to the cold storage assembly 120, such that the cold storage assembly 120 is movably connected to the container body 110 along a first direction D1. Specifically, the track assembly 160 includes pairs of tracks 161 arranged along the first direction, with adjacent tracks 161 spaced apart and opposite each other along a second direction perpendicular to the first direction. For example... Figure 5 In this configuration, the first direction is the length direction DL of the container 100, and correspondingly, the second direction is the height direction DH of the container 100. Preferably, the cross-sectional structure of the track 161 is U-shaped. When the cold storage assembly 120 is connected to the container body 110, along the second direction, the cold storage assembly 120 partially extends into the interior of two adjacent tracks 161, and the distance between the inner wall surfaces 162 of the two adjacent tracks 161 is greater than the size of the cold storage assembly 120. It is understood that the opening width of the track 161 is at least greater than the thickness of the portion of the cold storage assembly 120 located inside the track 161. This configuration allows for dimensional changes in the cold storage assembly 120 during use, ensuring its normal operation.

[0097] Please see Figure 7 and Figure 8The cold storage assembly 120 includes a housing 121, a phase change layer 122, and a sealing member. The housing 121 has a receiving cavity and an inlet 123 connecting the outside to the receiving cavity. The phase change layer 122 is located inside the housing 121. For example, phase change material is poured into the receiving cavity through the inlet 123, and then the sealing member is connected to the housing. It is understood that the sealing member is closable and openable connected to the inlet 123. It should be noted that the housing 121 is preferably constructed as a single piece, which avoids the risk of cracking and leakage due to transportation vibration compared to welding processes.

[0098] According to this utility model, the cold storage insulated container has a fixing component that cooperates with the inner wall of the container to restrict the position of the cold storage component along a first direction; correspondingly, the paired tracks can restrict the position of the cold storage component along a second direction, thereby effectively solving the problem that the cold storage component is difficult to fix due to volume changes before and after cold storage and release. The fixing component is easy to adjust to adapt to the cold storage component in different states, so that the same container can transport frozen goods or goods requiring different cooling capacities by changing different cold storage components.

[0099] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Terms such as “set” appearing herein can refer to either a component being directly attached to another component or a component being attached to another component via an intermediary. A feature described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0100] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this utility model to the described embodiments. Those skilled in the art will understand that many more variations and modifications can be made based on the teachings of this utility model, and all such variations and modifications fall within the scope of protection claimed by this utility model.
