[0042] In the description of the embodiments of the present application, "up", "down", "top", "bottom", orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] In the related art, the cabinet door cover of the refrigeration equipment is arranged on the main box, and the main box is opened or closed by rotating the cabinet door relative to the main box. Since the first hinge seat connected to the cabinet door is at least partially located in the mounting portion of the second mounting seat, during the process of opening and closing the cabinet door, the load of the cabinet door will act on the first hinge seat, so that the load of the cabinet door is transmitted to the mounting portion of the second hinge seat connected to the main box through the structure of the first hinge seat located in the mounting portion, which may cause damage to the mounting portion to a certain extent.

[0044] In view of this, the present application embodiment provides a hinge, please refer to Figures 1 to 8, including a first hinge seat 2 and a second hinge seat 3. The first hinge seat 2 is used to connect with a cabinet door 4. The second hinge seat 3 is arranged on the first hinge seat 2 so that the first hinge seat 2 can at least partially rotate relative to the second hinge seat 3. The central axis of the second hinge seat 3 rotating relative to the first hinge seat 2 is the target axis. The second hinge seat 3 has a mounting portion 312. The mounting portion 312 is located at one end of the second hinge seat 3 facing the first hinge seat 2 along the target axis. The first hinge seat 2 is partially located in the mounting portion 312; the first reinforcement member 5 is sleeved on the mounting portion 312, and the first reinforcement member 5 is located between the first hinge seat 2 and the second hinge seat 3 along the target axis.

[0045] In the embodiment of the present application, the first hinge seat 2 at least partially rotates relative to the second hinge seat 3, the second hinge seat 3 has a mounting portion 312, and the first reinforcement 5 is sleeved on the mounting portion 312. When the cabinet door 4 of the refrigeration equipment is rotated to open or close the main box 1, the load of the cabinet door 4 acts on the inner side of the mounting portion 312 through the structure of the first hinge seat 2 located in the mounting portion 312. Since the first reinforcement 5 is sleeved on the mounting portion 312, the first reinforcement 5 can apply a corresponding reaction force from the outside of the mounting portion 312 to reduce the possibility of cracking and other damage to the mounting portion 312, which can effectively improve the strength of the mounting portion 312 and reduce the possibility of cracking and other damage to the second hinge seat 3 due to excessive force during use, thereby improving the service life of the hinge seat.

[0046] In one embodiment, please refer to Figure 8 The first reinforcement member 5 is a closed structure connected end to end in a circumferential direction around the target axis.

[0047] Exemplarily, the first reinforcement member 5 is a closed annular structure connected end to end.

[0048] In the embodiment of the present application, the first reinforcement member 5 is a closed annular structure, so that the first reinforcement member 5 can passively apply a large reaction force from the outside of the mounting portion 312, thereby reducing damage to the mounting portion 312.

[0049] In one embodiment, the first reinforcement member 5 is made of metal.

[0050] In one embodiment, the first reinforcement member 5 is made of iron, steel, aluminum or an alloy.

[0051] In the embodiment of the present application, the material of the first reinforcement member 5 is a metal material selected from iron, steel, aluminum or alloy, which can improve the strength of the first reinforcement member 5 and effectively avoid the flexible deformation of the hinge seat.

[0052] In one embodiment, please refer to Figure 8 The hinge includes a second reinforcement member 22, which is mounted on an end of the first hinge seat 2 away from the second hinge seat 3 along the target axis.

[0053] In the embodiment of the present application, the second reinforcement 22 is arranged at one end of the first articulated seat 2 along the target axis away from the second articulated seat 3, which can improve the connection strength of the first articulated seat 2 and reduce the damage to the first articulated seat 2 caused by the load applied to the first articulated seat 2 by the cabinet door 4 during the process of opening and closing the main box 1. The position of the second reinforcement 22 can reduce the interference between the second reinforcement 22 and the second articulated seat 3 and / or the structure of one end of the first articulated seat 2 facing the second articulated seat 3, thereby facilitating installation.

[0054] In one embodiment, please refer to Figure 8 The first hinge seat 2 includes a rotating shaft 24 and a first seat body 21. The rotating shaft 24 is connected to the second hinge seat 3, and the second reinforcing member 22 is connected to the end of the rotating shaft 24 away from the second hinge seat 3; the first seat body 21 is sleeved on the rotating shaft 24 so that the first seat body 21 can rotate relative to the second hinge seat 3, and the second reinforcing member 22 abuts against the side of the first seat body 21 away from the second hinge seat 3 along the target axis.

[0055] In the embodiment of the present application, it can be connected to the second articulated seat 3, and the second reinforcement 22 is connected to the end of the rotating shaft 24 away from the second articulated seat 3. The second reinforcement 22 connected to the rotating shaft 24 abuts against the side of the first seat body 21 away from the second articulated seat 3 along the target axis. The first seat body 21 is constrained by the rotating shaft 24 and the second reinforcement 22, so that the first seat body 21 can be better installed on the second articulated seat 3.

[0056] Exemplarily, the target axis is the central axis of the rotating shaft.

[0057] Exemplarily, the first base body 21 may be made of plastic.

[0058] Exemplarily, the material of the first base body 21 may be plastic, and the material of the second reinforcement member 22 may be metal.

[0059] Exemplarily, the material of the first seat body 21 may be plastic, and the material of the second reinforcement member 22 may be iron, steel, aluminum or an alloy.

[0060] In one embodiment, please refer to Figure 8The first seat body 21 has a conversion cavity 214 and a conversion platform 215 located in the conversion cavity 214. The first articulated seat 2 also includes a converter 25 and an elastic member 6. The converter 25 is sleeved on the rotating shaft 24, and the converter 25 is movably arranged on the second articulated seat 3. The second articulated seat 3 limits the converter 25 from rotating in the circumferential direction of the converter 25. The converter 25 has a conversion surface 251 at one end facing the first seat body 21 along the axial direction of the rotating shaft 24. The conversion surface 251 is inclined along the circumferential direction of the converter 25. The converter 25 is at least partially located in the mounting portion 312, and the conversion platform 215 in the conversion cavity 214 abuts against the conversion surface 251. The elastic member 6 is sleeved on the rotating shaft 24, and the elastic member 6 is located at one end of the converter 25 along the axial direction of the rotating shaft 24 that is away from the conversion platform 215. The elastic member 6 contacts the converter 25 and the second articulated seat 3 respectively.

[0061] In the embodiment of the present application, the elastic member 6 applies an axial thrust to the converter 25 along the rotating shaft 24, and through the contact between the circumferentially inclined conversion surface 251 and the conversion platform 215, the axial force of the converter 25 is at least partially converted into a circumferential force applied by the conversion surface 251 to the conversion platform 215 for assisting in opening the cabinet door 4, so as to achieve easy opening of the cabinet door 4 or even to make the cabinet door 4 hover after opening the cabinet door 4. The load applied by the cabinet door 4 to the first seat body 21 applies a force to the inner side of the mounting portion 312 through the converter 25, and the first reinforcement member 5 sleeved on the mounting portion 312 can apply a corresponding reaction force to constrain the mounting portion 312, thereby reducing damage to the mounting portion 312 of the second hinge seat 3.

[0062] Exemplarily, the elastic member 6 may be a spring.

[0063] Exemplarily, when the cabinet door 4 is opened to the extreme position so that the first seat body 21 and the second hinge seat 3 are abutted and limited, the first seat body 21 uses the abutment and limit position of the first seat body 21 and the second hinge seat 3 as a fulcrum to tilt the rotating shaft 24 and the converter 25 located in the mounting portion 312 to apply force to the interior of the mounting portion 312.

[0064] It is understandable that the force applied to the inside of the mounting portion 312 is not limited to the converter 25. For example, the first hinge seat 2 may not be provided with the converter 25 and the elastic member 6, and the load applied by the cabinet door 4 to the first seat body 21 may be applied to the inner side of the mounting portion 312 through the rotating shaft 24. For example, the first hinge seat 2 may not be provided with the converter 25 and the elastic member 6, and the load applied by the cabinet door 4 to the first seat body 21 may be applied to the inner side of the mounting portion 312 through the structure in which the first seat body 21 is located inside the mounting portion 312.

[0065] In one embodiment, please refer to Figure 7 and Figure 8The rotating shaft 24 passes through the second reinforcement member 22 , and a stopper 241 is formed on the rotating shaft 24 , and the stopper 241 abuts against a side of the second reinforcement member 22 away from the second hinge seat 3 along the target axis.

[0066] For example, see Fig. 9 The stopper 241 is a riveted flange, and the stopper 241 of the rotating shaft 24 is a rivet hole. The rivet passes through the second reinforcement 22 and is connected to the rotating shaft 24 , and the rivet flange abuts against the second reinforcement 22 .

[0067] In the embodiment of the present application, the stopper 241 abuts against the second reinforcement member 22, so that the first seat body 21 and the first reinforcement member 5 and other components can be kept installed on the second hinge seat 3, and the second reinforcement member 22 can be kept installed on the first seat body 21, thereby reducing the possibility of the first seat body 21 being separated from the second hinge seat 3 and the possibility of the second reinforcement member 22 being separated from the first seat body 21. The stopper 241 allows the second reinforcement member 22 to be installed more firmly on the shaft 24, and the shaft 24 can apply a large pulling force to the second reinforcement member 22. The stopper 241 abuts against the second reinforcement member 22, which can reduce the damage to the first seat body 21 caused by the force applied by the stopper 241.

[0068] In one embodiment, please refer to Figure 8 A receiving groove 213 is formed on a side of the first seat body 21 away from the second hinge seat 3 along the target axis, and the second reinforcement member 22 is located in the receiving groove 213 .

[0069] In the embodiment of the present application, the first seat body 21 has a receiving groove 213, which can fix the reinforcement member on the first hinge seat 2 to prevent the second reinforcement member 22 from shifting during the rotation process.

[0070] In one embodiment, please refer to Figure 8 , the first hinge seat 2 has a mounting arm 212 for connecting to the cabinet door 4, the second reinforcement member 22 has a protruding reinforcement arm 222, and the reinforcement arm 222 abuts against a side of the mounting arm 212 away from the second hinge seat 3 along the target axis; or

[0071] The second reinforcement member 22 is in the shape of a circular ring.

[0072] In the embodiment of the present application, the second reinforcement member 22 has a protruding reinforcement arm 222, which can improve the strength of the mounting arm 212 of the first hinge seat 2 and prevent the mounting arm 212 from being deformed under the action of external force.

[0073] In one embodiment, the second reinforcement member 22 is made of metal.

[0074] In one embodiment, the second reinforcement member 22 is made of iron or steel.

[0075] Exemplarily, the material used for the second reinforcement member 22 is steel.

[0076] In the embodiment of the present application, the material of the second reinforcement 22 is a metal material selected from iron, steel, aluminum or alloy, which can improve the strength of the second reinforcement 22 and effectively bear the external force of the riveted flange without deformation.

[0077] In one embodiment, please refer to Figure 8 The second reinforcement member 22 has a first limiting portion 221 , and the first limiting portion 221 is arranged on an end of the second reinforcement member 22 close to the target axis.

[0078] Exemplarily, the first limiting portion 221 is a convex arc-shaped structure.

[0079] In the embodiment of the present application, the first limiting portion 221 abuts against the stop platform 211 of the first hinge seat 2, and the two have the same shape, which can increase the range of the load borne by the stop platform 211.

When the stop platform 211 abuts against the second limiting portion 121, the first limiting portion 221 abuts against the second limiting portion 121.

[0083] In the embodiment of the present application, the first limiting portion 221 is located on the side of the target axis of the stop platform 211 away from the second articulated seat 3. When the stop platform 211 abuts against the second limiting portion 121, the first limiting portion 221 also abuts against the second limiting portion 121. The first limiting portion 221 of the second reinforcement 22 can share the load of the stop platform 211, so that the second articulated seat 3 has higher strength when abutting, and better prevents the second articulated seat 3 from deformation and cracking.

[0084] Exemplarily, the first limiting portion 221 has the same shape as the stopping platform 211 .

[0085] In addition, the second hinge seat 3 has a clamping portion 311. When the first limiting portion 221 abuts against the second limiting portion 121, the clamping portion 311 abuts against one side of the mounting arm 212, which can increase the force bearing area of ​​the first hinge seat 2 and enable the first hinge seat 2 to bear a larger load.
