[0035] The mouth frame 1 of the refrigeration device 100 of this embodiment includes a plurality of strip-shaped mouth frame strips 11 and at least one strip-shaped insert 12. The mouth frame strips 11 are made of plastic and can be straight or curved. Figure 1 and Figure 4 As shown in the straight line bar. Figure 1 and Figure 4 As shown, multiple mouth frame strips 11 are connected end to end to form an annular plastic frame. The inserts 12 are made of metal, and at least one insert 12 is arranged along the extension direction of at least one mouth frame strip 11 and fixedly connected to the mouth frame strip 11. That is, at least one strip-shaped mouth frame strip 11 is arranged side by side with a strip-shaped metal insert 12 and fixedly connected to the mouth frame strip 11. The strip-shaped metal insert 12 fixedly connected to the mouth frame strip 11 extends in a direction that is substantially the same as the extension direction of the mouth frame strip 11.

[0036] Because the strip-shaped metal insert 12 has a lower shrinkage than the plastic mouth frame strip 11 at low temperatures, the mouth frame 1 of the refrigeration device 100 of this embodiment is fixedly connected to the mouth frame strip 11 by providing the strip-shaped metal insert 12 arranged along the extension direction of the mouth frame strip 11. When the plastic mouth frame strip 11 shrinks, the strip-shaped metal insert 12 can suppress the shrinkage of the mouth frame strip 11, thereby reducing the shrinkage rate of the mouth frame 1 at low temperatures.

[0037] In some embodiments, as Figure 4 As shown, the mouth frame includes multiple inserts 12, which are connected end to end to form an annular metal frame. The annular metal frame is fixedly connected to the annular plastic frame and is arranged around the annular plastic frame. This embodiment can further suppress the shrinkage of the mouth frame from the circumference, making the shrinkage suppression effect of the mouth frame more uniform at low temperatures, further improving the anti-shrinkage effect.

[0038] In some embodiments, as Figure 4 As shown, the mouth frame also includes a fixed connection device for fixedly connecting the annular metal frame and the annular plastic frame. The annular metal frame is a rectangular structure including four inserts 12, and the annular plastic frame is a rectangular structure including four mouth frame strips 11. The fixed connection device is composed of a first connection component and a second connection component. The first connection component and the second connection component respectively fix the two opposite inserts 12 of the annular metal frame and the two opposite mouth frame strips 11 of the annular plastic frame. In the embodiment shown in the figure, the first connection component and the second connection component are threaded connections. The first connection component fixes one mouth frame strip 11 and an insert 12 together by threaded connection, and the second connection component fixes the other opposite mouth frame strip 11 and an insert 12 together by threaded connection. In the embodiment shown in the figure, the first connection component and the second connection component are threaded connections. Figure 4 In the illustrated embodiment, the two long, opposing strips 11 of the mouth frame are directly fixedly connected to the two long, opposing strips of inserts 12 via a connecting assembly. The two short, opposing strips 11 of the mouth frame are not directly fixedly connected to the two short, opposing strips of inserts 12. Instead, the two short, opposing strips of inserts 12 are directly fixedly connected to the other two long, opposing strips of the mouth frame. In the illustrated embodiment, the four inserts 12 are fixedly connected at their joints by self-tapping screws. In this embodiment, because only the two opposing inserts 12 are directly fixedly connected to the two opposing strips of the mouth frame, while the other inserts 12 are not directly fixedly connected to the strips, the annular metal frame can reduce the shrinkage of the mouth frame at low temperatures. At the same time, the portion of the inserts and the mouth frame strips that are not directly connected allows the mouth frame to expand and contract adaptively at low temperatures while suppressing shrinkage at low temperatures, reducing the risk of the mouth frame strips fracturing when shrinkage is suppressed at low temperatures.

[0039] In some embodiments, as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the mouth frame strip 11 is provided with a first groove 111 extending along its extension direction. The insert 12 has a U-shaped cross-section and is disposed within the first groove 111 of the mouth frame strip 11 and fixedly connected to the groove wall and / or groove bottom of the first groove 111. The U-shaped insert 12 has greater structural strength, is more stable and reliable, and can better fit the first groove 111 while also preventing shrinkage of the mouth frame strip 11 from more directions.

[0040] In some embodiments, the mouth frame further includes a connecting assembly 13 for fixing the insert 12 to the mouth frame strip 11. The connecting assembly 13 includes a bolt 131 and a rivet nut 132 riveted to the mouth frame strip 11. The insert 12 and the mouth frame strip 11 are fixedly connected by the threaded engagement of the bolt 131 and the rivet nut 132. This embodiment makes the fixed connection between the insert 12 and the mouth frame strip 11 more convenient and reliable.

[0041] In some embodiments, the mouth frame further comprises a plurality of connection components for fixing and connecting the insert and the mouth frame strip, wherein the plurality of connection components are arranged at intervals along the extension direction of the mouth frame strip. Configuring a plurality of connection components can disperse stress and solve the problem of stress concentration.

[0042] In some embodiments, as Figure 5 and Figure 7 As shown, the mouth frame also includes joint anti-shrinkage members 14, which are fixedly connected to the two adjacent mouth frame strips 11 at the end-to-end junctions. In low-temperature environments, the mouth frame is more likely to shrink and crack at the joints of the mouth frame strips 11. The provision of joint anti-shrinkage members 14 can reduce the likelihood of shrinkage and cracking at the joints of the mouth frame, thereby improving the stability and reliability of the mouth frame.

[0043] In some embodiments, as Figure 7 As shown, at the end-to-end connection of two adjacent mouth frame strips 11, the two adjacent mouth frame strips 11 are perpendicular to each other. The joint anti-shrinkage member 14 is an L-shaped connector comprising two mutually perpendicular strip-shaped connecting portions 141. The two strip-shaped connecting portions 141 of the L-shaped connector are respectively fixedly connected to the two adjacent mouth frame strips 11. In this embodiment, the mouth frame strips 11 have 45° bevels at their ends. The adjacent mouth frame strips 11 are connected at a 45° angle at the end-to-end connection through the 45° bevels. The L-shaped connector is suitable for connecting adjacent mouth frame strips 11 at a 45° angle.

[0044] In some embodiments, the material of the mouth frame strip 11 is low-temperature resistant PP material, polypropylene, which is more suitable for low-temperature environments.

[0045] In some embodiments, a refrigeration device 100 is further disclosed. The refrigeration device 100 includes any of the above-mentioned opening frames 1 .

[0046] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the refrigeration device further includes a housing 2 and a door 31. The housing 2 includes an inner shell 22 and an outer shell 21. The inner shell 22 encloses a storage chamber 221 for storing objects at low temperatures. The opening frame 1 is connected between the inner shell 22 and the outer shell 21 and is used to cooperate with the door 31 to seal the storage chamber 221. In the embodiment shown in the figure, the storage chamber 221 is further divided into multiple small storage chambers.

[0047] In some embodiments, as Figures 1 to 6As shown, the mouth frame strip 11 includes a main plate 113 having a Z-shaped cross-section. The Z-shaped cross-section refers to a shape similar to the letter Z. The main plate 113 includes a first surface 1131 adjacent to the door body 31 and a second surface 1132 opposite the first surface 1131. The mouth frame strip 11 also includes a plurality of plates disposed on the second surface 1132 of the main plate 113 and protruding away from the first surface 1131. The plurality of plates include a first plate 1141 and a second plate 1142 forming a second groove 112 with the main plate 113. The second groove 112 extends along the extension direction of the mouth frame strip 11. The refrigeration device 100 also includes a condenser for dissipating heat from the refrigerant and an outlet pipe 43 connected to the outlet of the condenser. The outlet pipe 43 extends into the second groove 112 to prevent condensation on the mouth frame strip 11. This embodiment can better connect with the outer shell 21 and the inner shell 22 through the setting of the Z-shaped main plate 113. The first plate 1141 and the second plate 1142 form a second groove, and the outlet pipe 43 is introduced. The refrigerant with a certain temperature coming out of the condenser can be used to heat the mouth frame, evaporate the condensed water on the mouth frame, and prevent condensation on the mouth frame.

[0048] In some embodiments, the refrigeration device 100 further includes a foam body disposed between the outer shell 21 and the inner shell 22. The box body 2 is a foam box body. The multiple plates include a third plate 1143 fixedly connected to the inner shell 22. The outer shell 21 includes a U-shaped bent portion 211 that contacts both the main plate 113 and the first plate 1141. The foam body presses the bent portion 211 against the first plate 1141 and the main plate 113. In this embodiment, the mouth frame is fixedly connected to the inner shell 22 by means of a threaded connection or the like, and then the main plate and the outer shell 21 are connected without a connector. Instead, the bent portion 211 is designed to press the foam body. This ensures the reliability of the connection between the mouth frame and both the inner shell 22 and the outer shell 21, and makes the connection between the mouth frame and the outer shell more flexible and convenient.

[0049] In some embodiments, the refrigeration device 100 is a refrigerator, specifically an ultra-low temperature storage refrigerator.
