Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, display cases have refrigerated compartments inside, creating a refrigerated environment for storing items.

[0003] Refrigeration equipment typically includes a cabinet and a door. The cabinet contains a storage compartment, and the door is rotatably connected to the cabinet to open or close the refrigerated compartment for storing items. A frame is positioned on the periphery of the cabinet near the opening of the storage compartment to support the foaming process of the cabinet.

[0004] Currently, the reinforcing iron is fixed to the box frame using multiple spring clips. However, due to the limited space for installing the reinforcing iron, the spring clip structure is constrained by the installation space and cannot provide a stronger reinforcement effect. Furthermore, during the installation process, multiple clips need to be manually pried open to insert the reinforcing iron, reducing installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigeration device that facilitates the rapid installation of reinforcing iron on the box frame and meets the requirements for the fixed connection strength between the reinforcing iron and the box frame.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; the housing having a refrigeration chamber; a frame disposed within the housing; a reinforcing member disposed on the inner wall of the frame, the reinforcing member having a insertion hole; and a connector disposed on the inner wall of the frame, the connector corresponding to the insertion hole, the connector including: a connecting arm protruding from the inner wall of the frame, the connecting arm for passing through the insertion hole; and an elastic arm, one end of the elastic arm being connected to the end of the connecting arm away from the frame, the other end of the elastic arm extending towards the side closer to the frame and spaced apart from the connecting arm, the elastic arm being spaced apart from the frame; the connector is capable of being aligned and inserted into the insertion hole, such that the connecting arm passes through the insertion hole, and the elastic arm abuts against the inner wall of the reinforcing member, so that the reinforcing member is clamped between the elastic arm and the frame.

[0008] The above technical solution has the following advantages or beneficial effects: By connecting one end of the elastic arm to the end of the connecting arm away from the box frame, and extending the other end towards the side closer to the box frame and spaced apart from the connecting arm, while the elastic arm is spaced apart from the box frame, the elastic arm forms a cantilever structure. Thus, when the elastic arm is under force, the end connected to the connecting arm is fixedly constrained, while the other end of the elastic arm is spaced apart from the connecting arm to allow for a certain degree of elastic deformation. When the connector is inserted into the insertion hole, the connecting arm passes through the insertion hole. As the insertion process proceeds, the elastic arm is compressed by the inner wall of the reinforcing member and undergoes elastic deformation. After insertion, the elastic arm, due to its own elastic restoring force, will tightly abut against the inner wall of the reinforcing member, thereby clamping the reinforcing member between the elastic arm and the inner wall of the box frame. The clamping effect of the elastic arm on the reinforcing member provides a stronger reinforcement and fixation effect, which can effectively prevent the reinforcing member from loosening or falling off during use. On the other hand, when installing the reinforcing member, you only need to align the connector with the connector hole and insert it to complete the installation, which greatly improves the installation efficiency.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein two elastic arms are provided, and the two elastic arms are respectively disposed on opposite sides of the connecting arm; when the plug is aligned and inserted into the plug hole, the two elastic arms can respectively abut against the inner walls of the reinforcing members on opposite sides of the plug hole.

[0010] Another technical solution described above has the following advantages or beneficial effects: by distributing the elastic arms on opposite sides of the connecting arm, a double-sided abutment structure can be formed for the reinforcing member. When the connector is inserted, the two elastic arms can apply clamping force to the parts of the reinforcing member located on both sides of the insertion hole. Compared to a single-sided clamping structure, the double-sided clamping structure in this embodiment is more stable, providing better resistance to pull-out and vibration, making the reinforcing member less prone to loosening or displacement during long-term use.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein one end of the elastic arm connected to the connecting arm is a fixed end, the end of the elastic arm away from the connecting arm is a suspended end, the fixed end is connected to the end of the connecting arm away from the inner wall of the box frame, the suspended ends are arranged at intervals on one side of the connecting arm, and the suspended ends are arranged at intervals from the inner wall of the box frame.

[0012] Another technical solution described above has the following advantages or beneficial effects: When the connector is inserted into the insertion hole of the reinforcing member, the inner wall of the insertion hole will compress the suspended end of the elastic arm. Because the suspended end and the connecting arm are spaced apart and have sufficient deformation space, the elastic arm can undergo elastic bending deformation with the fixed end as the fulcrum, and automatically spring back after insertion, thus tightly abutting against the inner wall of the reinforcing member, achieving reliable clamping and fixing. At the same time, compared with traditional fixing and clamping methods, the elastic rebound clamping of the reinforcing member by the elastic arm can better adapt to changes in the shape and size of the inner wall of the reinforcing member, improving the stability and reliability of the clamping.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the elastic arm includes a connecting section disposed between the fixed end and the suspended end; the connecting section has a pressing surface on the side away from the fixed end, and the pressing surface extends obliquely toward the side away from the connecting arm in the direction from the fixed end toward the suspended end, and the end of the pressing surface away from the fixed end is located outside the insertion hole.

[0014] Another technical solution described above has the following advantages or beneficial effects: By providing a pressing surface on the side of the connecting section away from the fixed end, and because the pressing surface is inclined, the pressing action causes the elastic arm to gradually deform elastically starting from the position near the fixed end. This gradual compression deformation of the elastic arm can prevent the elastic arm from being damaged by excessive concentrated force instantaneously. On the other hand, the inclined pressing surface can guide the insertion of the connector and the reinforcing member during the insertion process, thereby preventing jamming at the contact position during insertion, improving the smoothness of insertion, and thus enhancing the convenience of assembly and the accuracy of insertion alignment.

[0015] In some embodiments of this application, a refrigeration device is provided, wherein a guide slope is provided on the side of the suspended end away from the connecting arm, one end of the guide slope near the connecting section is connected to the extrusion surface, and the other end of the guide slope away from the connecting section extends toward the bottom wall of the box frame and the connecting arm; a limiting groove is provided on the other end of the guide slope near the box frame, and the wall of the insertion hole is engaged in the limiting groove.

[0016] Another technical solution described above has the following advantages or beneficial effects: Due to the guide slope connected to the extrusion surface, and the guide surface extending towards the bottom wall of the box frame and the connecting arm, a buffer path is provided when the connector is about to reach the final insertion position, reducing insertion resistance and improving insertion smoothness. Furthermore, after the connector is installed in place, the hole wall of the insertion hole is engaged in the limiting groove. This limiting groove provides a fixed engagement position for the hole wall of the insertion hole and increases the contact area between the reinforcing member and the connector, thereby increasing the contact area and friction at the connection point and effectively preventing axial or radial movement between the connector and the hole wall.

[0017] In some embodiments of this application, a cooling device is provided, wherein a positioning groove is provided on the side edge of the insertion hole, the positioning groove is connected to the insertion hole, and the positioning groove is arranged opposite to the connecting arm; a positioning rib is provided on the side of the connecting arm facing the positioning groove; when the connecting arm passes through the insertion hole, the positioning rib is engaged with the positioning groove.

[0018] Another technical solution described above has the following advantages or beneficial effects: By setting a positioning groove on the side edge of the insertion hole and arranging it opposite to the connecting arm, and providing a positioning rib on the side of the connecting arm facing the positioning groove, the cooperation between the positioning groove and the positioning rib during the installation of the connector provides a precise positioning reference for the installation of the connecting arm within the insertion hole. Furthermore, the installer only needs to align the positioning rib on the connecting arm with the positioning groove on the side edge of the insertion hole, and then push the connector to allow the connecting arm to pass through the insertion hole, thus completing the initial positioning and installation, thereby reducing the installation difficulty and improving installation efficiency.

[0019] In some embodiments of this application, a refrigeration device is provided, wherein the reinforcing member is elongated; a buckle is provided on the inner wall of the box frame, the buckle and one end of the reinforcing member are arranged opposite each other along the length direction, and an abutment groove is formed between the buckle and the inner wall of the box frame; one end of the reinforcing member along the length direction is inserted into the abutment groove, so that one end of the reinforcing member is clamped between the buckle and the inner wall of the box frame; the other end of the reinforcing member along the length direction is provided with the insertion hole; the other end of the reinforcing member along the length direction is connected to the insertion member through the insertion hole, so that the other end of the reinforcing member is clamped between the elastic arm and the box frame.

[0020] Another technical solution described above has the following advantages or beneficial effects: By setting a snap fastener to form an abutment groove with the inner wall of the box frame, one end of the reinforcing member in the extension direction is inserted into the abutment groove, thereby limiting and clamping one end of the reinforcing member. In terms of structural stability, one end of the reinforcing member is clamped between the snap fastener and the inner wall of the box frame, and the other end is clamped between the elastic arm and the box frame, thus forming a stable clamping support structure at both ends of the reinforcing member. This can prevent external forces such as vibration and extrusion deformation during the operation of the refrigeration unit or during the foaming process of the box body, thereby avoiding deformation of the box body after foaming. In terms of installation, the matching design of the snap fastener and the connector makes the installation structure of the reinforcing member and the box frame relatively simple. Installers only need to align one end of the reinforcing member with the abutment groove and insert it, then mate the other end's connector hole with the connector to complete the installation. This reduces complex positioning and fixing steps during installation, not only lowering the installation difficulty but also improving installation efficiency.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein a fixing plate is provided on the inner wall of the box frame, the fixing plate is located at the end of the reinforcing member away from the insertion hole along the length direction; a buckle is located on the side of the fixing plate facing the insertion member, and the buckle and the inner wall of the box frame form the abutment groove; when the reinforcing member is inserted into the abutment groove, the end of the reinforcing member abuts against the fixing plate and is clamped between the buckle and the inner wall of the box frame.

[0022] Another technical solution described above has the following advantages or beneficial effects: the fixing plate can act as an end limiting member. During the insertion of one end of the reinforcing member into the abutment groove, when the end of the reinforcing member abuts against the fixing plate, it can prevent the reinforcing member from continuing to move during insertion. At this time, the reinforcing member is properly inserted into the abutment groove. On the other hand, after the reinforcing member is inserted into the abutment groove, the fixing plate, the buckle, and the inner wall of the box frame limit the end of the reinforcing member from different directions. This can effectively improve the stability of the reinforcing member at the end and thus prevent the reinforcing member from detaching from the box frame.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein a first limiting plate is provided on the side wall of the fixing plate, the first limiting plate extending from the side wall of the fixing plate toward the reinforcing member; a second limiting plate is provided on the side wall of the fixing plate, the second limiting plate being spaced apart on one side of the first limiting plate, the second limiting plate extending from the side wall of the fixing plate toward the reinforcing member; when the reinforcing member is inserted into the abutment groove, both sides of the reinforcing member are respectively clamped between the first limiting plate and the second limiting plate.

[0024] Another technical solution described above has the following advantages or beneficial effects: the first and second limiting plates can limit the lateral sides of the reinforcing member. When the reinforcing member is inserted into the abutment groove, both sides of the reinforcing member are respectively clamped between the first and second limiting plates. That is, the first and second limiting plates simultaneously limit the two opposite sides of the reinforcing member, which can effectively prevent the reinforcing member from laterally swaying or displacing after insertion.

[0025] In some embodiments of this application, a refrigeration device is provided. The reinforcing member includes a first reinforcing plate, which is fitted onto the inner wall of the box frame and has the insertion hole; a second reinforcing plate, which is bent and extended from one side edge of the first reinforcing plate in the width direction toward the inner wall away from the box frame; and a third reinforcing plate, which is bent and extended from the other side edge of the first reinforcing plate in the width direction toward the inner wall away from the box frame. The end of the first reinforcing plate is inserted into the abutment groove, the corresponding end of the second reinforcing plate is inserted between the first limiting plate and the buckle, and the corresponding end of the third reinforcing plate is inserted between the second limiting plate and the buckle.

[0026] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the second and third reinforcing plates can serve as reinforcing ribs on the edge of the first reinforcing plate. The structure formed by the first, second, and third reinforcing plates can prevent the reinforcing member from bending, warping, or torsional deformation during the stress process, thereby improving the load-bearing capacity and structural stability of the reinforcing member. When the end of the first reinforcing plate is inserted into the abutment groove, the second and third reinforcing plates are respectively embedded between the first and second limiting plates and the snap fastener, thereby limiting the reinforcing member on both sides along the width direction. Moreover, under the combined action of the fixing plate, the snap fastener, the first limiting plate, and the second limiting plate, one end of the reinforcing member is clamped and constrained in multiple directions, effectively preventing the reinforcing member from loosening, shaking, or displacing on the box frame.

[0047] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0048] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0049] like Figure 1 As shown, the refrigerator provided in this embodiment of the present invention includes a cabinet 1. The cabinet 1 can adopt a hollow structure such as a cuboid. The cabinet 1 forms the outer shell of the refrigeration device. It should be noted that the cabinet 1 can also adopt a hollow shell structure of other shapes.

[0050] In some embodiments, the interior of the housing 1 forms a refrigeration chamber (not shown in the figure). The top of the refrigeration chamber may have an opening. Multiple refrigeration chambers may be provided.

[0051] In some embodiments, multiple refrigeration compartments can serve as independent storage spaces, such as freezers, refrigerators, and variable-temperature compartments, to meet different refrigeration needs, such as freezing, refrigeration, and variable-temperature storage, depending on the type of food, and to store items that require refrigeration or freezing. Multiple refrigeration compartments can be arranged vertically or horizontally.

[0052] In some embodiments, the refrigeration device may include a liner (not shown in the figures). The liner may be disposed within the housing 1. A refrigeration compartment may be formed within the liner.

[0053] In some embodiments, a foam layer (not shown in the figure) is formed between the peripheral wall of the liner and the box body 1. The foam layer is used to fill the foam material. Since the foam material has thermal insulation properties, it can effectively reduce the heat transfer from the refrigeration room to the outside, thereby helping to reduce the energy consumption of the refrigeration device, maintain a constant low temperature environment in the refrigeration room, and ensure the quality of the stored items.

[0054] like Figure 1 As shown, in some embodiments, the refrigeration unit includes a door 11. The door 11 is located on the front side of the housing 1 for opening and closing the refrigeration compartment.

[0055] It should be noted that multiple doors 11 can be installed. Each door 11 can be installed in a one-to-one correspondence with a refrigeration room. Multiple doors 11 can open and close a single refrigeration room simultaneously. A single door 11 can also open and close multiple refrigeration rooms simultaneously.

[0056] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor, as the power source of the refrigeration cycle, draws in low-temperature, low-pressure refrigerant gas and compresses it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0057] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser receives refrigerant flowing from the compressor, cools the high-temperature, high-pressure refrigerant gas from the compressor, and converts it into a liquid state. The condenser transfers heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0058] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0059] In some embodiments, the refrigeration system may include an evaporator (not shown). A throttling device delivers a throttled and depressurized refrigerant into the evaporator. The evaporator is used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0060] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0061] Figure 2 for Figure 1 A partial schematic diagram; Figure 3 for Figure 2 Schematic diagram of the fit between the middle box frame and the reinforcing member; Figure 4 for Figure 3 An exploded view. It should be noted that... Figure 2 for Figure 1 A diagram showing what's behind the hidden door.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 1 may include a frame 2. The frame 2 may be disposed on the housing 1 to enhance the structural strength of the housing 1.

[0063] In some embodiments, the foaming space has an opening (not shown) around the top opening 101 of the refrigeration chamber, and the frame 2 can cover the opening. The frame 2 can be connected between the box body 1 and the box liner, wherein the inner side of the frame 2 can be connected to the box liner, and the outer side of the frame 2 can be connected to the box body 1, thereby closing the opening of the foaming space.

[0064] The frame 2 serves to support the foaming process of the housing 1. During the manufacturing process of the refrigeration device, the frame 2 provides structural support for the foaming process of the housing 1, enabling the foamed material to be filled according to the predetermined shape and structure, thereby forming a stable and reliable housing 1 structure.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration device includes a reinforcing member 3. The reinforcing member 3 may be disposed on the inner wall of the frame 2. By providing the reinforcing member 3 on the frame 2, the reinforcing member 3 can effectively resist the deformation force generated on the box body 1 and the box liner during the foaming process of the foaming space, thereby enhancing the structural strength and stability of the frame 2.

[0066] In some embodiments, the frame 2 is connected between the housing 1 and the inner liner. When the refrigeration compartment has a top opening 101, the reinforcing member 3 can be correspondingly disposed on the bottom wall of the frame 2. Thus, the reinforcing member 3 can fit against the bottom wall of the frame 2, thereby providing structural support for the frame. It should be noted that in some other embodiments, the reinforcing member 3 can be disposed on the side wall of the frame 2, which can be disposed adjacent to the bottom wall. Since the reinforcing member 3 is disposed on the frame 2, the structural strength of the frame 2 is improved, enabling the frame 2 to effectively resist deformation forces.

[0067] In some other embodiments, the frame 2 can be disposed on the door 11, and correspondingly, the reinforcing member 3 can be disposed on the side of the door 11 facing the foaming space. It should be noted that the cooperation structure of the frame 2 and the reinforcing member 3 disclosed in this application is not limited to the application of the door 11 or the side of the box 1 near the opening of the foaming space mentioned above.

[0068] Figure 5 for Figure 3 A magnified view of section A in the image.

[0069] like Figure 3 and Figure 5 As shown, in some embodiments, the refrigeration device includes a connector 21. The connector 21 may be disposed on the inner wall of the frame 2. The reinforcing member 3 is provided with a connector hole 301. The connector 21 is disposed corresponding to the connector hole 301. The connector 21 can be inserted into the connector hole 301, thereby fixing the reinforcing member 3 to the inner wall of the frame 2.

[0070] Specifically, the inner wall of the box frame 2 can be the side facing the foaming space. The plug-in 21 is set on the inner wall of the box frame 2 and can extend towards the side where the foaming space is located. After the plug-in hole 301 of the reinforcing member 3 is aligned and plugged into the plug-in 21 on the box frame 2, the reinforcing member 3 can be fixed on the side of the box frame 2 facing the foaming space.

[0071] In some embodiments, the connector 21 can be integrally connected to the box frame 2.

[0072] like Figure 5 As shown, in some embodiments, the connector 21 may include a connecting arm 211. The connecting arm 211 protrudes from the inner wall of the frame 2 and is used to pass through the connector hole 301. Since the connecting arm 211 protrudes from the inner wall of the frame 2, it can play a role in positioning and initial connection during the installation of the reinforcing member 3 and the frame 2. Specifically, the connector hole 301 on the reinforcing member 3 is aligned before the connecting arm 211, and the connecting arm 211 helps to accurately guide the connector 21 into the connector hole 301, ensuring accurate alignment between the connector 21 and the reinforcing member 3.

[0073] like Figure 5 As shown, in some embodiments, the connector 21 may include an elastic arm 212. One end of the elastic arm 212 is connected to the end of the connecting arm 211 away from the frame 2. The other end of the elastic arm 212 extends toward the side closer to the frame 2 and is spaced apart from the connecting arm 211, with the elastic arm 212 and the frame 2 spaced apart. The connector 21 can be aligned and inserted into the connector hole 301, so that the connecting arm 211 passes through the connector hole 301, and the elastic arm 212 abuts against the inner wall of the reinforcing member 3, so that the reinforcing member 3 is clamped between the elastic arm 212 and the frame 2.

[0074] In this design, one end of the elastic arm 212 is connected to the end of the connecting arm 211 away from the frame 2, while the other end extends towards the side closer to the frame 2 and is spaced apart from the connecting arm 211. The elastic arm 212 is cantilevered, allowing it to undergo elastic deformation. When the elastic arm 212 is under stress, the end connected to the connecting arm 211 is fixed, while the other end is spaced apart to allow for elastic deformation. When the connector 21 is inserted into the connector hole 301, the connecting arm 211 passes through it. As the insertion process progresses, the elastic arm 212 is compressed by the inner wall of the reinforcing member 3, resulting in elastic deformation. After insertion, the elastic arm 212, due to its elastic restoring force, abuts tightly against the inner wall of the reinforcing member 3, thus clamping the reinforcing member 3 between the elastic arm 212 and the inner wall of the frame 2. The clamping effect of the elastic arm 212 on the reinforcing member 3 can provide a stronger reinforcement and fixation effect, which can effectively prevent the reinforcing member 3 from loosening or falling off during use. On the other hand, when installing the reinforcing member 3, the installation can be completed simply by aligning the connector 21 with the connector hole 301 and inserting it, which greatly improves the installation efficiency.

[0075] Currently, the reinforcing iron is fixed to the box frame 2 using multiple spring clips. However, due to the limited space for installing the reinforcing iron, the spring clip structure is constrained by the installation space and cannot provide a stronger reinforcement effect. Furthermore, during the installation process, multiple clips need to be manually pried open to insert the reinforcing iron, reducing installation efficiency.

[0076] In this embodiment, a connector 21 is provided on the frame 2 to be inserted into the insertion hole 301 of the reinforcing member 3. The connector 21 includes a connecting arm 211 and an elastic arm 212. The connecting arm 211 protrudes outward from the inner wall of the frame 2 and is used to pass through the insertion hole 301 on the reinforcing member 3. One end of the elastic arm 212 is connected to the end of the connecting arm 211 away from the frame 2, and the other end extends towards the side closer to the frame 2. A gap can be formed between the elastic arm 212 and the connecting arm 211 to clamp the reinforcing member 3 between the elastic arm 212 and the frame 2. By having the elastic arm 212 abut against the inner wall of the reinforcing member 3, this application achieves a clamping and fixed state of the reinforcing member 3 between the inner wall of the frame 2 and the elastic arm 212, thereby enhancing the structural stability and vibration resistance of the reinforcing member 3 during use and effectively preventing the reinforcing member 3 from loosening or falling off during use. Compared to the existing technology that uses multiple spring clips for fixing, this application eliminates the need to manually pry open multiple clips to complete the installation of the reinforcing iron. By setting up a plug-in structure composed of connecting arm 211 and elastic arm 212, a one-way insertion is used to complete a stable fixation, making the operation quick and easy. On the other hand, even when the installation space is limited, the elastic arm 212 of the plug-in 21 can still firmly clamp the reinforcing member 3, improving the reliability and stability of the assembly of the plug-in 21 and the reinforcing member 3 in a small space.

[0077] In some embodiments, multiple connectors 21 may be provided, and multiple connector slots may be provided on the reinforcing member 3 accordingly.

[0078] like Figure 5 As shown, in some embodiments, two elastic arms 212 may be provided. The two elastic arms 212 may be respectively provided on opposite sides of the connecting arm 211. When the connector 21 is aligned and inserted into the connector hole 301, the two elastic arms 212 can respectively abut against the inner walls of the reinforcing members 3 on opposite sides of the connector hole 301.

[0079] By distributing the elastic arms 212 on opposite sides of the connecting arm 211, a double-sided abutment structure can be formed for the reinforcing member 3. Specifically, when the connector 21 is inserted, the two elastic arms 212 can apply clamping force to the parts of the reinforcing member 3 located on both sides of the connector hole 301. Compared with a single-sided clamping structure, the double-sided clamping structure in this embodiment is more stable and can provide better resistance to pull-out and vibration, making the reinforcing member 3 less prone to loosening or displacement during long-term use.

[0080] On the other hand, since only one elastic arm 212 is provided, when the box frame 2 or the reinforcing member 3 is subjected to force, the plug-in member 21 is prone to deflection or tilting, which leads to the instability of the connection structure between the reinforcing member 3 and the box frame 2. However, by setting the elastic arm 212 on the opposite sides of the connecting arm 211, this situation can be effectively avoided, thereby enhancing the reliability of the connection between the reinforcing member 3 and the box frame 2.

[0081] In some embodiments, the two elastic arms 212 may be symmetrically arranged on opposite sides of the connecting arm 211.

[0082] In some embodiments, multiple elastic arms 212 may be provided. Multiple elastic arms 212 may be spaced apart on the periphery of the connecting arm 211.

[0083] Figure 6 for Figure 3 A cross-sectional view; Figure 7 for Figure 3 Another perspective of the cross-section.

[0084] like Figure 6 and Figure 7 As shown, in some embodiments, the end of the elastic arm 212 connected to the connecting arm 211 can be a fixed end 2121. The end of the elastic arm 212 away from the connecting arm 211 can be a suspended end 2122. The fixed end 2121 is connected to the end of the connecting arm 211 away from the inner wall of the box frame 2, and the suspended ends 2122 are arranged at intervals on one side of the connecting arm 211, and are arranged at intervals from the inner wall of the box frame 2.

[0085] In this design, by connecting the fixed end 2121 of the elastic arm 212 to the end of the connecting arm 211 that is away from the box frame 2, the elastic arm 212 is arranged in a cantilevered manner with one end fixed and the other end suspended, which is beneficial for the elastic arm 212 to achieve good elastic deformation performance during the insertion process.

[0086] Specifically, when the connector 21 is inserted into the insertion hole 301 of the reinforcing member 3, the inner wall of the insertion hole 301 will compress the suspended end 2122 of the elastic arm 212. Since the suspended end 2122 is spaced apart from the connecting arm 211 and has sufficient deformation space, the elastic arm 212 can undergo elastic bending deformation with the fixed end 2121 as the fulcrum, and automatically spring back after being inserted into place, thereby tightly abutting against the inner wall of the reinforcing member 3 and achieving reliable clamping and fixing. At the same time, compared with the traditional fixed clamping method, the elastic rebound clamping of the reinforcing member 3 by the elastic arm 212 can better adapt to the shape and size changes of the inner wall of the reinforcing member 3, improving the stability and reliability of clamping.

[0087] like Figure 6 and Figure 7As shown, in some embodiments, the elastic arm 212 may include a connecting segment 2123. The connecting segment 2123 is disposed between the fixed end 2121 and the suspended end 2122. The connecting segment 2123 has a pressing surface 202 on the side away from the fixed end 2121. In the direction from the fixed end 2121 to the suspended end 2122, the pressing surface 202 extends obliquely toward the side away from the connecting arm 211, and the end of the pressing surface 202 away from the fixed end 2121 is located outside the insertion hole 301.

[0088] The connecting segment 2123 connects the fixed end 2121 and the suspended end 2122, and is spaced apart on one side of the connecting arm 211. By providing a pressing surface 202 on the side of the connecting segment 2123 away from the fixed end 2121, and by extending the pressing surface 202 at an angle away from the connecting arm 211 in the direction from the fixed end 2121 to the suspended end 2122, the distance between the outer side of the connecting segment 2123 and the connecting arm 211 gradually increases. During the insertion of the connector 21 into the connector hole 301, as the connector 21 penetrates deeper into the connector hole 301, the inner wall of the reinforcing member 3 gradually presses the connecting segment 2123 of the elastic arm 212 along the pressing surface 202. Because the pressing surface 202 is inclined, the pressing action causes the elastic arm 212 to gradually deform elastically starting from a position close to the fixed end 2121. This gradual compression deformation of the elastic arm 212 avoids damage caused by excessive concentrated force applied instantaneously. On the other hand, the inclined pressing surface 202 can guide the insertion of the connector 21 and the reinforcing member 3 during the insertion process, thereby avoiding jamming at the contact position of the two during the insertion process, improving the smoothness of the insertion, and thus improving the convenience of assembly and the accuracy of insertion alignment.

[0089] It should be noted that the connection point between the connecting section 2123 and the suspended end 2122 is located outside the outline of the insertion hole 301, and at least a portion of the suspended end 2122 is located outside the outline of the insertion hole 301. In this way, the portion of the suspended end 2122 located outside the outline of the insertion hole 301 can abut the reinforcing member 3 against the box frame 2.

[0090] like Figure 6 As shown, in some embodiments, the connection between the connecting segment 2123 and the fixed end 2121 can be a circular arc transition.

[0091] like Figure 6 As shown, in some embodiments, a guide slope 203 may be provided on the side of the suspended end 2122 away from the connecting arm 211. The end of the guide slope 203 near the connecting section 2123 is connected to the extrusion surface 202, and the end of the guide slope 203 away from the connecting section 2123 extends toward the bottom wall of the box frame 2 and the connecting arm 211.

[0092] The guide slope 203 is connected to the extrusion surface 202 on the connecting section 2123. The end of the guide slope 203 away from the connecting section 2123 extends towards the bottom wall of the box frame 2 and the connecting arm 211. That is, the inclination direction of the guide slope 203 and the extrusion surface 202 are opposite. The connection point between the extrusion surface 202 and the guide slope 203 is the farthest point of the elastic arm 212 from the connecting arm 211. During the process of inserting the connector 21 into the insertion hole 301, the insertion hole 301 first slides gradually along the extrusion surface 202 towards the inner wall of the box frame 2 and extrudes the elastic arm 212, applying a gradually increasing extrusion force to the elastic arm 212. Then, the hole wall of the insertion hole 301 contacts the guide slope 203 and deflects along its direction to guide it to the final contact position. Because of the guide slope 203 connected to the extrusion surface 202, and the guide surface extending towards the bottom wall of the box frame 2 and the connecting arm 211, a buffer path is provided when the plug-in part 21 is about to reach the final plug-in position, reducing plug-in resistance and improving plug-in smoothness.

[0093] like Figure 6 and Figure 7 As shown, in some embodiments, a limiting groove 204 is provided at one end of the guide slope 203 near the box frame 2, and the hole wall of the insertion hole 301 is engaged in the limiting groove 204. By providing a limiting groove 204 at one end of the guide slope 203 near the box frame 2, when the insertion member 21 is inserted into the insertion hole 301, the limiting groove 204 can engage with the hole wall of the insertion hole 301, thereby firmly abutting the reinforcing member 3 against the inner wall of the box frame 2.

[0094] Specifically, when the connector 21 is installed in place, the wall of the connector hole 301 is engaged in the limiting groove 204. In this way, the limiting groove 204 provides a fixed engaging position for the wall of the connector hole 301. Moreover, the limiting groove 204 can increase the contact area between the reinforcing member 3 and the connector 21, thereby increasing the contact area and friction of the connection between the two, effectively preventing axial or radial movement between the connector 21 and the wall of the connector hole 301.

[0095] like Figure 6 and Figure 7 As shown, in some embodiments, the limiting groove 204 can be a stepped groove.

[0096] Figure 8 for Figure 3 Another cross-sectional view; Figure 9 for Figure 3 A schematic diagram of the middle box frame.

[0097] like Figure 8 and Figure 9As shown, in some embodiments, a positioning groove 302 may be provided at the side edge of the insertion hole 301. The positioning groove 302 communicates with the insertion hole 301. The positioning groove 302 is arranged opposite to the connecting arm 211. A positioning rib 213 may be provided on the side of the connecting arm 211 facing the positioning groove 302. When the connecting arm 211 is inserted into the insertion hole 301, the positioning rib 213 is engaged with the positioning groove 302.

[0098] Because positional deviations can easily occur during installation, the connector 21 may not be installed accurately, affecting the connection between the reinforcing member 3 and the frame 2. To address this, a positioning groove 302 is provided on the side edge of the connector hole 301, positioned opposite the connecting arm 211. The connecting arm 211 has a positioning rib 213 on the side facing the positioning groove 302. During the installation of the connector 21, the cooperation of the positioning groove 302 and the positioning rib 213 provides a precise positioning reference for the connecting arm 211 within the connector hole 301. Specifically, the positioning groove 302 spatially restricts the movement of the connecting arm 211 in the direction perpendicular to the axis of the connector hole 301, effectively preventing deviations in the insertion position of the connector 21 and the reinforcing member 3.

[0099] On the other hand, the installer only needs to align the positioning rib 213 on the connecting arm 211 with the positioning groove 302 on the side edge of the insertion hole 301, and then push the insertion piece 21 to make the connecting arm 211 pass into the insertion hole 301 to complete the initial positioning and installation. This can reduce the installation difficulty and thus improve the installation efficiency.

[0100] In some embodiments, two elastic arms 212 may be arranged opposite to each other on both sides of the connecting arm 211 and respectively on both sides of the positioning groove 302.

[0101] Figure 10 for Figure 3 Schematic diagram of the central reinforcement component; Figure 11 for Figure 3 A magnified view of section B in the image.

[0102] like Figure 10 As shown, in some embodiments, the reinforcing member 3 can be elongated. The length of the reinforcing member 3 can extend along one side of the box frame 2, thus enabling the box frame 2 to provide better support.

[0103] like Figure 10 and Figure 11As shown, in some embodiments, a buckle 22 may be provided on the inner wall of the box frame 2. The buckle 22 and one end of the reinforcing member 3 are arranged opposite each other along the length direction, and an abutment groove 201 may be formed between the buckle 22 and the inner wall of the box frame 2. One end of the reinforcing member 3 along the length direction is inserted into the abutment groove 201, so that one end of the reinforcing member 3 is clamped between the buckle 22 and the inner wall of the box frame 2. The other end of the reinforcing member 3 along the length direction may be provided with a insertion hole 301. The other end of the reinforcing member 3 along the length direction is connected to the insertion member 21 through the insertion hole 301, so that the other end of the reinforcing member 3 is clamped between the elastic arm 212 and the box frame 2.

[0104] In this design, by setting the buckle 22 to form an abutment groove 201 with the inner wall of the box frame 2, one end of the reinforcing member 3 in the extension direction is inserted into the abutment groove 201, thereby limiting and clamping one end of the reinforcing member 3.

[0105] In terms of structural stability, one end of the reinforcing member 3 is clamped between the snap fastener 22 and the inner wall of the box frame 2, and the other end is clamped between the elastic arm 212 and the box frame 2, thus forming a stable clamping and supporting structure at both ends of the reinforcing member 3. In this way, external forces such as vibration and extrusion deformation can be prevented from being subjected to during the operation of the refrigeration unit or during the foaming process of the box body 1, thereby avoiding deformation of the box body 1 after foaming. Even after long-term use, the reinforcing member 3 can still be firmly fixed to the box frame 2, ensuring the reliability and safety of the overall structure of the refrigeration unit.

[0106] In terms of installation, the matching arrangement of the buckle 22 and the connector 21 makes the installation structure of the reinforcing member 3 and the box frame 2 relatively simple. Specifically, the installer only needs to align one end of the reinforcing member 3 with the abutment groove 201 and insert it, and then connect the other end of the reinforcing member 3 with the connector 21 to complete the installation. This reduces the complicated positioning and fixing steps during the installation process, which not only reduces the installation difficulty but also helps to improve the installation efficiency.

[0107] like Figure 10 As shown, in some embodiments, the reinforcing member 3 may have insertion holes 301 at opposite ends along its length. When the frame 2 has only one insertion member 21, providing two insertion holes 301 on the reinforcing member 3 facilitates installation. Specifically, during the installation of the reinforcing iron, the installer does not need to distinguish which end of the reinforcing member 3 needs to mate with the insertion member 21; one end of the reinforcing iron can mate with the insertion member 21 regardless of the specific end required.

[0108] In some embodiments, the reinforcing member 3 may have insertion holes 301 with the same shape at opposite ends along its length.

[0109] In some other embodiments, one end of the reinforcing member 3 can be fixed to the box frame 2 by a connector, and the other end of the reinforcing member 3 can be fixed to the box frame 2 by a plug-in member 21. The connector can refer to screws, bolts, etc.

[0110] In some other embodiments, the reinforcing member 3 may have insertion holes 301 at both ends along its length. The box frame 2 is provided with insertion members 21 at the positions corresponding to the insertion holes 301, thereby clamping the two ends of the reinforcing member 3 along its length between the elastic arm 212 and the box frame 2.

[0111] like Figure 8 and Figure 9 As shown, in some embodiments, the inner wall of the box frame 2 may be provided with a fixing plate 23. The fixing plate 23 is located at the end of the reinforcing member 3 along its length away from the insertion hole 301. A buckle 22 is located on the side of the fixing plate 23 facing the insertion member 21, and an abutment groove 201 is formed between the buckle 22 and the inner wall of the box frame 2. When the reinforcing member 3 is inserted into the abutment groove 201, the end of the reinforcing member 3 abuts against the fixing plate 23 and is clamped between the buckle 22 and the inner wall of the box frame 2.

[0112] Among them, a fixing plate 23 is provided on the inner wall of the box frame 2. The fixing plate 23 can be vertically protruding on the inner wall of the box frame 2. The buckle 22 is provided on the fixing plate 23 and the buckle 22 is spaced apart from the inner wall of the box frame 2. The abutment groove 201 can be formed between the fixing plate 23, the buckle 22 and the inner wall of the box frame 2.

[0113] Specifically, the fixing plate 23 can act as an end limiting member. During the process of inserting one end of the reinforcing member 3 into the abutment groove 201, when the end of the reinforcing member 3 abuts against the fixing plate 23, it can prevent the reinforcing member 3 from continuing to move during insertion. At this time, the reinforcing member 3 is properly inserted into the abutment groove 201. On the other hand, after the reinforcing member 3 is inserted into the abutment groove 201, the fixing plate 23, the buckle 22, and the inner wall of the box frame 2 limit the end of the reinforcing member 3 from different directions. This can effectively improve the stability of the reinforcing member 3 at the end and thus prevent the reinforcing member 3 from detaching from the box frame 2.

[0114] like Figure 9 and Figure 11 As shown, in some embodiments, a first limiting plate 24 may be provided on the side wall of the fixing plate 23. The first limiting plate 24 extends from the side wall of the fixing plate 23 toward the side of the reinforcing member 3. A second limiting plate 25 may be provided on the side wall of the fixing plate 23. The second limiting plate 25 is spaced apart on one side of the first limiting plate 24, and extends from the side wall of the fixing plate 23 toward the side of the reinforcing member 3. When the reinforcing member 3 is inserted into the abutment groove 201, both sides of the reinforcing member 3 are respectively clamped between the first limiting plate 24 and the second limiting plate 25.

[0115] The first limiting plate 24 and the second limiting plate 25 are respectively disposed on both sides of the fixed plate 23. The first limiting plate 24 and the second limiting plate 25 are spaced apart to form a limiting gap for accommodating the reinforcing member 3. Moreover, the first limiting plate 24 and the second limiting plate 25 extend from the side wall of the fixed plate 23 toward the reinforcing member 3. The first limiting plate 24 and the second limiting plate 25 can limit the lateral sides of the reinforcing member 3.

[0116] Specifically, when the reinforcing member 3 is inserted into the abutment groove 201, both sides of the reinforcing member 3 are clamped between the first limiting plate 24 and the second limiting plate 25, that is, the first limiting plate 24 and the second limiting plate 25 simultaneously limit the two opposite sides of the reinforcing member 3, which can effectively prevent the reinforcing member 3 from swaying or displacing laterally after insertion.

[0117] On the other hand, the first limiting plate 24 and the second limiting plate 25 play a guiding role during the insertion of the reinforcing member 3 into the abutment groove 201. When installing the reinforcing member 3, the installer only needs to insert the reinforcing member 3 along the space between the first limiting plate 24 and the second limiting plate 25 to ensure that the reinforcing member 3 is accurately positioned in the lateral direction. This simplifies the installation operation and reduces the adjustment steps required due to positional deviations during the installation process.

[0118] like Figure 10 and Figure 11 As shown, in some embodiments, the reinforcing member 3 may include a first reinforcing plate 31. The first reinforcing plate 31 is fitted onto the inner wall of the box frame 2. The first reinforcing plate 31 is provided with an insertion hole 301. The first reinforcing plate 31 serves as the main bearing surface and fitting surface of the reinforcing member 3. Specifically, the first reinforcing plate 31 may be elongated, and the extension direction of the first reinforcing plate 31 is the same as the extension direction of one side of the box frame 2. When the first reinforcing plate 31 is inserted into the abutment groove 201, the first limiting plate 24 and the second limiting plate 25 can limit the reinforcing plate on both sides along the width direction.

[0119] like Figure 10 and Figure 11 As shown, in some embodiments, the reinforcing member 3 may include a second reinforcing plate 32 and a third reinforcing plate 33. The second reinforcing plate 32 is bent and extended from one side edge of the first reinforcing plate 31 in the width direction toward the inner wall away from the box frame 2. The third reinforcing plate 33 is bent and extended from the other side edge of the first reinforcing plate 31 in the width direction toward the inner wall away from the box frame 2. The end of the first reinforcing plate 31 is inserted into the abutment groove 201, the corresponding end of the second reinforcing plate 32 is inserted between the first limiting plate 24 and the buckle 22, and the corresponding end of the third reinforcing plate 33 is inserted between the second limiting plate 25 and the buckle 22.

[0120] Among them, the second reinforcing plate 32 and the third reinforcing plate 33 can serve as reinforcing ribs on the edge of the first reinforcing plate 31. The structure of the first reinforcing plate 31, the second reinforcing plate 32 and the third reinforcing plate 33 forming the reinforcing member 3 can prevent the reinforcing member 3 from bending, warping or torsional deformation during the stress process, thereby improving the load-bearing capacity and structural stability of the reinforcing member 3.

[0121] Specifically, when the end of the first reinforcing plate 31 is inserted into the abutment groove 201, the second reinforcing plate 32 and the third reinforcing plate 33 are respectively embedded between the first limiting plate 24, the second limiting plate 25 and the buckle 22, thereby limiting the reinforcing member 3 on both sides along the width direction. Moreover, the ends of the second reinforcing plate 32 and the third reinforcing plate 33 abut against the fixing plate 23, so that after the reinforcing member 3 is inserted into the abutment groove 201, under the combined action of the fixing plate 23, the buckle 22, the first limiting plate 24 and the second limiting plate 25, one end of the reinforcing member 3 is clamped and constrained in multiple directions, effectively preventing the reinforcing member 3 from loosening, shaking and displacement on the box frame 2.

[0122] like Figure 10 As shown, in some embodiments, the first reinforcing plate 31, the second reinforcing plate 32, and the third reinforcing plate 33 can form a structure similar to a "U" or a "C".

[0123] like Figure 6 As shown, in some embodiments, the first reinforcing plate 31, the second reinforcing plate 32, and the third reinforcing plate 33 can form a long strip structure in the shape of a "U".

[0124] like Figure 6 As shown, in some embodiments, the box frame 2 can have a U-shaped structure. Reinforcing members 3 can be correspondingly disposed on each side of the box frame 2 to structurally reinforce each side of the box frame 2.

[0125] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
