[0012] In some embodiments, it further includes a joint shrinkage prevention member. At the head and tail connection of two adjacent mouth frame bars, the joint shrinkage prevention member is fixedly connected to the two adjacent mouth frame bars simultaneously.

[0013] In some embodiments, at the head and tail connection of two adjacent mouth frame bars, the two adjacent mouth frame bars are perpendicular to each other. The joint shrinkage prevention member is an L-shaped connecting member including two mutually perpendicular strip-shaped connecting parts. The two strip-shaped connecting parts of the L-shaped connecting member are fixedly connected to the two adjacent mouth frame bars simultaneously.

[0014] The second aspect of the present invention discloses a refrigeration device including any one of the mouth frames.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way constitutes a limitation on the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above terms have no special meaning and thus cannot be construed as limiting the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to include different orientations during use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, a device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0036] As Figures 1 to 9 shown, the mouth frame 1 of the refrigeration device in this embodiment includes a plurality of strip-shaped mouth frame bars 11. The mouth frame bars 11 are made of plastic, and the mouth frame bars 11 can be straight strip-shaped or curved strip-shaped. Usually, as Figure 3 and Figure 6 shown, they are straight strip-shaped. As Figure 3 and Figure 6 shown, the plurality of mouth frame bars 11 are connected end to end to form an annular plastic frame body. As Figure 1 , Figure 2 , Figure 5 and Figure 8 shown, the mouth frame 1 of the refrigeration device further includes a metal wire embedded in the cross-section of the mouth frame bar 11 and extending along the extension direction of the mouth frame bar 11. In the cross-sectional view of the mouth frame bar 11 as shown in Figure 1 and Figure 8 shown, the cross-section of the metal wire can be seen. The cross-section of the metal wire is located within the cross-section of the mouth frame bar 11, that is, the metal wire 15 is embedded inside the mouth frame bar 11 in this embodiment, and the metal wire 15 is strip-shaped, and the extension direction of the strip-shaped metal wire 15 is the same as the extension direction of the mouth frame bar 11. The plastic mouth frame bar can be melted by heating, and then the metal wire can be extruded into the mouth frame bar. The metal wire material can be stainless steel or other materials.

[0037] Since the shrinkage of the metal wire at low temperatures is less than that of the plastic mouth frame bar 11. In this embodiment, by embedding a metal wire 15 extending along the extension direction of the mouth frame bar 11 in the cross-section of the mouth frame bar 11, when the plastic mouth frame bar 11 shrinks, the metal wire can inhibit the shrinkage of the mouth frame bar 11, thereby reducing the shrinkage rate of the mouth frame 1 at low temperatures.

[0038] In some embodiments, as Figure 2As shown, a plurality of protruding portions 16 that protrude radially outward along the wire are provided on the surface of the wire 15. By providing the protruding portions 16 on the wire, when the mouth frame strip contracts, the wire can better transmit the acting force with the mouth frame strip 11 through the protruding portions 16, better inhibit the contraction of the mouth frame strip, and reduce the contraction rate of the mouth frame strip. In some embodiments, the plurality of protruding portions 16 are evenly arranged on the wire, and the protruding portions 16 are metal blocks.

[0039] In some embodiments, the wire is an annular wire surrounding the cross-section of a plurality of mouth frame strips 11. As Figure 6 shown, the mouth frame 1 is a closed annular structure, and the wire is also a closed annular structure arranged around the mouth frame 1. The annular wire can better match the annular mouth frame 1 and play a role in inhibiting contraction on the entire circumference of the mouth frame. In some embodiments, the wire is bonded to the mouth frame. After the mouth frame is inserted into the wire in a molten state, the mouth frame can solidify and bond to the surface of the wire.

[0040] In some embodiments, the plurality of mouth frame strips 11 are integrally formed. The mouth frame in this embodiment is an integrally formed injection-molded part. The mouth frame is integrally formed, which reduces the number of connectors and connection seams compared to forming a frame structure by splicing a plurality of mouth frame strips 11 or connecting them through connectors, and can reduce the contraction rate of the mouth frame. In some embodiments, as shown in the figure, the width of the cross-section of the mouth frame strip 11 is 10 mm, and the diameter of the wire is 1.5 mm.

[0041] In some embodiments, the mouth frame 1 of the refrigeration device 100 in this embodiment further includes at least one strip-shaped insert 12. The insert 12 is made of metal, and at least one insert 12 is arranged along the extending 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 and a strip-shaped metal insert 12 are arranged side by side and fixedly connected, and the strip-shaped extending direction of the strip-shaped metal insert 12 fixedly connected to the mouth frame strip 11 is substantially the same as the extending direction of the mouth frame strip 11.

[0042] Since the shrinkage of the strip-shaped metal insert 12 at low temperature is less than that of the plastic mouth frame strip 11. For the mouth frame 1 of the refrigeration device 100 in this embodiment, by providing the strip-shaped metal insert 12 arranged along the extending direction of the mouth frame strip 11 and fixedly connected to the mouth frame strip 11, when the plastic mouth frame strip 11 shrinks, the strip-shaped metal insert 12 can inhibit the contraction of the mouth frame strip 11, thereby reducing the contraction rate of the mouth frame 1 at low temperature.

[0043] In some embodiments, as Figure 6 and Figure 7As shown, the mouth frame includes a plurality of inserts 12. The plurality of inserts 12 are connected end to end to form an annular metal frame body. The annular metal frame body is fixedly connected to the annular plastic frame body, and the annular metal frame body is arranged around the annular plastic frame body. This embodiment can further suppress the shrinkage of the mouth frame as a whole in the circumferential direction, making the shrinkage suppression effect of the mouth frame more uniform at low temperatures and further improving the anti-shrinkage effect.

[0044] In some embodiments, as Figure 6 shown, the mouth frame further includes a fixing connection device for fixedly connecting the annular metal frame body and the annular plastic frame body. The annular metal frame body is a rectangular structure including four inserts 12, and the annular plastic frame body is a rectangular structure including four mouth frame bars 11. The fixing connection device is composed of a first connection component and a second connection component. The first connection component and the second connection component respectively fixedly connect two opposite inserts 12 of the annular metal frame body with two opposite mouth frame bars 11 of the annular plastic frame body. In the embodiment shown in the figure, the first connection component and the second connection component are threaded connectors. The first connection component fixedly connects a mouth frame bar 11 and an insert 12 through threaded connection, and the second connection component fixedly connects another opposite mouth frame bar 11 and an insert 12 through threaded connection. In as Figure 6 shown in the embodiment, that is, the two long and opposite strip-shaped mouth frame bars 11 of the mouth frame are directly fixedly connected to the two long and opposite strip-shaped inserts 12 through the connection component, and the two short and opposite strip-shaped mouth frame bars 11 of the mouth frame are not directly fixedly connected to the two short and opposite strip-shaped inserts 12. The two short and opposite strip-shaped inserts 12 are directly fixedly connected to the other two long and opposite strip-shaped mouth frame bars 11. In the embodiment shown in the figure, the four inserts 12 are fixedly connected at the joints by self-tapping screws. In this embodiment, since only two opposite inserts 12 are directly fixedly connected to two opposite mouth frame bars of the mouth frame, and the other inserts 12 are not directly fixedly connected to the mouth frame bars, the annular metal frame body can play a role in reducing the shrinkage rate of the mouth frame under low-temperature action. At the same time, the parts of the inserts and mouth frame bars that are not directly fixedly connected can allow the mouth frame to adaptively expand and contract at this part while suppressing the shrinkage of the mouth frame at low temperatures, reducing the risk of the mouth frame bars breaking when the shrinkage of the mouth frame is suppressed at low temperatures.

[0045] In some embodiments, as Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a first groove 111 extending along the extension direction of the mouth frame bar 11 is provided on the mouth frame bar 11. The cross-section of the insert 12 is U-shaped. The insert 12 is arranged in the first groove 111 of the mouth frame bar 11 and is fixedly connected to the groove wall and / or the groove bottom of the first groove 111. The U-shaped insert 12 has greater structural strength, is more stable and reliable, can better fit the first groove 111, and can also inhibit the shrinkage of the mouth frame bar 11 from more directions.

[0046] In some embodiments, the mouth frame further includes a connection assembly 13 for fixedly connecting the insert 12 and the mouth frame bar 11. The connection assembly 13 includes a bolt 131 and a rivet nut 132 riveted on the mouth frame bar 11. The insert 12 and the mouth frame bar 11 are fixedly connected through the threaded fit of the bolt 131 and the rivet nut 132. This embodiment makes the fixed connection between the insert 12 and the mouth frame bar 11 more convenient and reliable.

[0047] In some embodiments, the mouth frame further includes a plurality of connection assemblies for fixedly connecting the insert and the mouth frame bar. The plurality of connection assemblies are arranged at intervals along the extension direction of the mouth frame bar where they are located. Arranging a plurality of connection assemblies can disperse stress and solve the problem of stress concentration.

[0048] In some embodiments, as Figure 7 and Figure 9 shown, the mouth frame further includes a joint anti-shrinkage member 14. At the head and tail connection of two adjacent mouth frame bars 11, the joint anti-shrinkage member 14 is fixedly connected to the two adjacent mouth frame bars 11 respectively. In a low-temperature environment, the joint connection of the mouth frame bars 11 is more likely to shrink and crack. By providing the joint anti-shrinkage member 14, the possibility of shrinkage and cracking at the joint connection of the mouth frame can be reduced, and the stability and reliability of the mouth frame can be improved.

[0049] In some embodiments, as Figure 9 shown, at the head and tail connection of two adjacent mouth frame bars 11, the two adjacent mouth frame bars 11 are perpendicular to each other. The joint anti-shrinkage member 14 is an L-shaped connecting member including two mutually perpendicular strip-shaped connecting parts 141. The two strip-shaped connecting parts 141 of the L-shaped connecting member are fixedly connected to the two adjacent mouth frame bars 11 respectively. In this embodiment, the mouth frame bar 11 is provided with a 45° inclined surface at the end, and the adjacent mouth frame bars 11 form a 45° connection through the 45° inclined surface at the head and tail connection. The L-shaped connecting member is suitable for the 45° connection of the adjacent mouth frame bars 11.

[0050] In some embodiments, the material of the mouth frame bar 11 is a low-temperature resistant PP material, polypropylene, which is more suitable for a low-temperature environment.

[0051] In some embodiments, a refrigeration device 100 is also disclosed. The refrigeration device 100 includes any one of the above-mentioned mouth frames 1.

[0052] In some embodiments, as Figure 3 、 Figure 4 andFigure 5 As shown, the refrigeration device further includes a box body 2 and a door body 31. The box body 2 includes an inner housing 22 and an outer housing 21. The inner housing 22 defines an accommodation chamber 221 for storing objects at low temperature. The door frame 1 is connected between the inner housing 22 and the outer housing 21 and is used to cooperate with the door body 31 to seal the accommodation chamber 221. In the embodiment shown in the figure, the accommodation chamber 221 is further divided into a plurality of small accommodation chambers.

[0053] In some embodiments, as Figures 3 to 8 shown, the door frame strip 11 includes a main board body 113 with a cross-section similar to the shape of the letter Z. The shape similar to the letter Z means that the shape is similar to the letter Z. The main board body 113 includes a first surface 1131 close to the door body 31 and a second surface 1132 opposite to the first surface 1131. The door frame strip 11 further includes a plurality of plate bodies provided on the second surface 1132 of the main board body 113 and protruding in a direction away from the first surface 1132. The plurality of plate bodies include a first plate body 1141 and a second plate body 1142 that form a second groove 112 with the main board body 113. The second groove 112 extends along the extending direction of the door frame strip 11. The refrigeration device 100 further includes a condenser for dissipating heat of the refrigerant and an outlet pipe 43 communicating with the outlet of the condenser. The outlet pipe 43 extends into the second groove 112 to prevent the door frame strip 11 from generating condensed water. In this embodiment, through the setting of the main board body 113 with a shape similar to the letter Z, it can be better connected with the outer housing 21 and the inner housing 22. The first plate body 1141 and the second plate body 1142 form a second groove, and by introducing the outlet pipe 43, the refrigerant with a certain temperature coming out of the condenser can be used to heat the door frame, evaporating the condensed water on the door frame and preventing the door frame from generating condensed water.

[0054] In some embodiments, the refrigeration device 100 further includes a foaming body provided between the outer housing 21 and the inner housing 22. The box body 2 is a foamed box body. The plurality of plate bodies include a third plate body 1143 fixedly connected to the inner housing 22. The outer housing 21 includes a U-shaped bent portion 211 that is in contact with both the main board body 113 and the first plate body 1141. The foaming body presses the bent portion 211 against the first plate body 1141 and the main board body 113. In this embodiment, the door frame is fixedly connected to the inner housing 22 through the third plate body 1143 by means of threaded connection or the like. Then, the main board body is not connected to the outer housing 21 by using a connecting member, but by a method of pressing with the foaming body through the design of the bent portion 211, which can not only ensure the connection reliability between the door frame and the inner housing 22 and the outer housing 21, but also make the connection between the door frame and the outer housing more flexible and convenient.

[0055] In some embodiments, the refrigeration device 100 is a refrigerator, specifically a cryogenic storage refrigerator.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
