It should be noted that the hinge mechanism 100 in this embodiment is not only applicable to the refrigeration device 1000, but also to other application scenarios, such as microwave ovens, electric ovens, disinfection cabinets, cabinets, wardrobes, wine cabinets, etc., but is not limited to this.

[0039] Please also read Figures 2 to 3 , Figure 2 yes Figure 1 Enlarged view of part A in the middle; Figure 3 yes Figure 1Enlarged view of the middle B part. The refrigeration device 1000 includes a box body 200 and a door body 300. The door body 300 is formed with a mounting groove 301, and the hinge mechanism 100 includes a first mounting seat 110 and a second mounting seat 120. The first mounting seat 110 is used to be arranged on the side of the box body 200 facing the door body 300. The second mounting seat 120 is used to be arranged in the mounting groove 301. The hinge assembly 130 includes a first connecting rod 131, a second connecting rod 132, a third connecting rod 133 and a fourth connecting rod 134. One end of the first connecting rod 131 is hinged to the first mounting seat 110, and the other end is hinged to one end of the second connecting rod 132. The other end of the second connecting rod 132 is hinged to the second mounting seat 120. One end of the third connecting rod 133 is hinged to the first mounting seat 110, and the other end is hinged to one end of the fourth connecting rod 134. The other end of the fourth connecting rod 134 is hinged to the second mounting seat 120. The second link 132 is also hinged to the third link 133 .

[0040] By setting the first mounting seat 110 on the side of the box body 200 facing the door body 300, the second mounting seat 120 is set in the mounting groove 301, and the hinge assembly 130 is hinged between the first mounting seat 110 and the second mounting seat 120, the hinge mechanism 100 will not protrude from the top of the refrigeration device 1000, thereby improving the aesthetics of the refrigeration device 1000. In addition, when the refrigeration device 1000 is embedded in the cabinet, since the hinge mechanism 100 will not protrude from the top of the refrigeration device 1000, the hinge mechanism 100 will not occupy the space of the cabinet, thereby improving the space utilization rate of the cabinet.

[0041] Before assembling the hinge mechanism 100 to the refrigeration device 1000, the first connecting rod 131 and the second connecting rod 132 can be assembled into a whole, the third connecting rod 133 and the fourth connecting rod 134 can be assembled into a whole, and then the second connecting rod 132 and the third connecting rod 133 can be hinged; during the installation process of the hinge mechanism 100, the first mounting seat 110 can be set on the side of the box body 200 facing the door body 300, and the second mounting seat 120 can be set in the mounting groove 301, and then The hinge mechanism 100 can be assembled by hingedly connecting one end of the first connecting rod 131 to the first mounting seat 110, hingedly connecting the other end of the second connecting rod 132 away from the first connecting rod 131 to the second mounting seat 120, hingedly connecting one end of the third connecting rod 133 to the first mounting seat 110, and hingedly connecting the other end of the fourth connecting rod 134 away from the third connecting rod 133 to the second mounting seat 120. The hinge mechanism 100 has a simple structure and is easy to assemble, which reduces the difficulty of assembly, saves working hours, and improves assembly efficiency.

[0042] In some embodiments, the door body 300 can be opened to a maximum angle relative to the box body 200 through the hinge mechanism 100, and the maximum angle is greater than or equal to 180 degrees.

[0043] The first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 can be relatively rotated to a first position state and a second position state. When the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 are rotated to the first position state, the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 are in a folded state, and the door body 300 is in a closed state relative to the box body 200, that is, the angle of the door body 300 relative to the box body 200 is 0°. During the process of the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 relatively rotating from the first position state to the second position state, the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 are gradually unfolded, and the door body 300 is gradually opened relative to the box body 200. When the first connecting rod 131 , the second connecting rod 132 , the third connecting rod 133 and the fourth connecting rod 134 rotate relatively to the second position, the door body 300 opens to the maximum angle relative to the box body 200 .

[0044] When the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 are relatively rotated to the second position, the door body 300 is opened to a maximum angle relative to the cabinet 200, and the maximum angle is greater than or equal to 180 degrees. If the refrigeration device 1000 is an embedded refrigeration device 1000 embedded in a cabinet, when the door body 300 is opened to 180 degrees relative to the cabinet 200, the door body 300 can be prevented from occupying the space around the cabinet, thereby improving the user experience.

[0045] In some embodiments, please refer to Figure 1 The door body 300 has two end plates 302 arranged opposite to each other in the direction from the top to the bottom of the refrigeration device 1000. The mounting groove 301 is formed on one side of the two end plates 302. The mounting groove 301 has a mounting wall surface 3011, and the plane where the mounting wall surface 3011 is located is parallel to the plane where the end plates 302 are located. The second mounting seat 120 is used to be arranged on the mounting wall surface 3011.

[0046] The mounting groove 301 is formed on one side of the two end plates 302 for connecting the cabinet 200. The mounting groove 301 is a depression that the end plate 302 sinks toward the inside of the door body 300, and the mounting wall 3011 of the mounting groove 301 can be a bottom wall that is recessed away from the end plate 302. The plane where the mounting wall 3011 of the mounting groove 301 is located is perpendicular to the arrangement direction from the top to the bottom of the refrigeration device 1000, and is parallel to the plane where the end plate 302 is located. The mounting groove 301 has at least one notch, and the notch of the mounting groove 301 facilitates the hinge assembly 130 to be connected between the first mounting seat 110 and the second mounting seat 120, and at the same time, the first connecting rod 131, the second connecting rod 132, the third connecting rod 133 and the fourth connecting rod 134 will not interfere with the end plate 302 or other parts of the door body 300 during the relative rotation.

[0047] In some embodiments, please refer to Figures 4 to 6 , Figure 4 It is a structural schematic diagram of an implementation mode of the hinge mechanism provided in the present application; Figure 5 is a structural schematic diagram of another embodiment of the hinge mechanism provided in the present application; Figure 6 : is a schematic diagram of the exploded structure of the hinge assembly of the hinge mechanism provided in the present application. The orthographic projection of the second connecting rod 132 on the plane where the installation wall 3011 is located at least partially falls on the third connecting rod 133. The orthographic projection of the second connecting rod 132 falling on the third connecting rod 133 has a first axial hole 132a corresponding to the position of the second connecting rod 132. The third connecting rod 133 has a second axial hole 133a corresponding to the position of the orthographic projection of the second connecting rod 132 falling on the third connecting rod 133, that is, the third connecting rod 133 has a second axial hole 133a adapted to the first axial hole 132a. The hinge mechanism 100 includes a first connecting component 141. The first connecting component 141 is used to cooperate with the first axial hole 132a and the second axial hole 133a so that the second connecting rod 132 is hinged to the third connecting rod 133. The first connecting component 141 can be an axial component such as a rivet or a pin, but is not limited to this.

[0048] The second connecting rod 132 includes a first rod portion 1321 and a second rod portion 1322 connected to the first rod portion 1321. One end of the first rod portion 1321 is hinged to the first connecting rod 131, and the other end is connected to the second rod portion 1322. The other end of the second rod portion 1322 away from the first rod portion 1321 is hinged to the second mounting seat 120. The width of the first rod portion 1321 gradually increases from the end hinged to the first connecting rod 131 to the end connected to the second rod portion 1322. The second rod portion 1322 is an arc-shaped rod portion protruding toward the direction of the fourth connecting rod 134, and such a shape can prevent the second rod portion 1322 from interfering with the inner wall of the mounting groove 301. The third connecting rod 133 includes a third rod portion 1331 and a fourth rod portion 1332 connected to the third rod portion 1331. One end of the third rod portion 1331 is hinged to the first mounting seat 110, and the other end is connected to the fourth rod portion 1332. The other end of the fourth rod portion 1332 away from the third rod portion 1331 is hinged to the fourth connecting rod 134. The third rod portion 1331 and the fourth rod portion 1332 are both arc-shaped rod portions convex toward one side, and such a shape can prevent the third connecting rod 133 from interfering with the inner wall of the mounting groove 301.

[0049] The first shaft hole 132a is formed at a side of the first rod portion 1321 close to the second rod portion 1322. The second shaft hole 133a is formed at the connection between the third rod portion 1331 and the fourth rod portion 1332. It can be understood that the orthographic projection of the second connecting rod 132 on the plane where the installation wall 3011 is located at least partially falls on the connection between the third rod portion 1331 and the fourth rod portion 1332, and the part of the orthographic projection of the second connecting rod 132 on the plane where the installation wall 3011 is located that falls on the connection between the third rod portion 1331 and the fourth rod portion 1332 corresponds to the position of the second connecting rod 132, which is the side of the first rod portion 1321 close to the second rod portion 1322, so that a first axial hole 132a can be opened on the side of the first rod portion 1321 of the second connecting rod 132 close to the second rod portion 1322, and a second axial hole 133a can be opened at the connection between the third rod portion 1331 and the fourth rod portion 1332 of the third connecting rod 133, and the first connecting component 141 cooperates with the first axial hole 132a and the second axial hole 133a to make the second connecting rod 132 and the third connecting rod 133 hinged, thereby improving the structural reliability and stability of the hinge mechanism 100.

[0050] In some embodiments, the first connecting rod 131 is arranged in an arc shape to form a first avoidance space 131 a on a side close to the third connecting rod 133 , and the first avoidance space 131 a is used to avoid the third connecting rod 133 .

[0051] The first avoidance space 131a formed by the first link 131 can be used to avoid the third link 133 when the door 300 is opened relative to the box body 200, so that the first link 131 will not interfere with the third link 133 during the opening of the door 300 relative to the box body 200.

[0063] See also Figures 7 to 9 , Figure 7 is a top view of an implementation of the refrigeration device provided by the present application; Figure 8 yes Figure 7 Enlarged view of middle C; Fig. 9 It is a structural schematic diagram of an implementation method of the first mounting seat of the hinge mechanism provided in the present application. First, a structure of the first mounting seat 110 is introduced in the case where the first mounting seat 110 is arranged on the third mounting seat 151 or the third mounting seat 151 and the first frame strip 211. When the first mounting seat 110 is arranged on the third mounting seat 151 or the third mounting seat 151 and the first frame strip 211, a second mounting seat 120 is arranged on the mounting groove 301 corresponding to the first mounting seat 110 of the door body 300. The first mounting seat 110 includes a first bottom plate 111 and a second bottom plate 112 connected to the first bottom plate 111. The first bottom plate 111 is used to set the first mounting seat 110 on the third mounting seat 151 or the third mounting seat 151 and the first frame strip 211. A mounting body 113 is formed on the side of the second bottom plate 112 facing away from the first bottom plate 111. An angle G is formed between one side of the mounting body 113 and the second bottom plate 112, and the angle G is an obtuse angle, that is, the mounting body 113 extends obliquely from the second bottom plate 112 toward the direction in which the door body 300 is opened to the maximum angle relative to the box body 200, thereby avoiding interference between the door body 300 and the box body 200 or the cabinet during the process of opening the door body 300 relative to the box body 200. When the door body 300 is closed relative to the box body 200, at least part of the mounting body 113 is accommodated in the mounting groove 301. By making the angle G between one side of the mounting body 113 and the second bottom plate 112 an obtuse angle, the door body 300 can be closed relative to the box body 200, and the mounting body 113 will not interfere with the second mounting seat 120 in the mounting groove 301. A second avoidance space 1131 is formed on the other side of the mounting body 113, and the second avoidance space 1131 is used to avoid the box body 200.

[0064] In some embodiments, the angle G between the mounting body 113 and the second base plate 112 is 145°-160°. For example, the angle G between the mounting body 113 and the second base plate 112 can be 145°, 145.5°, 145.8°, 146.2°, 146.5°, 146.8°, 147°, 147.5°, 147.7°, 148°, 148.55°, 148.6°, 148.7°, 148.8 ... °, 148.8°, 149°, 149.53°, 149.7°, 150°, 150.5°, 150.78°, 151°, 151.33°, 151.5°, 151.9°, 152°, 152.55°, 152.9°, 153°, 153.2°, 153.52°, 153.8°, 154°, 154.5°, 154.7° 4.8°, 155°, 155.5°, 155.8°, 156°, 156.7°, 157°, 157.5°, 157.65°, 158°, 158.5°, 158.8°, 159°, 159.4°, 159.7°, 160°, etc., or a range consisting of any two of the above values, for example, 145°-148°, 145°- 150°, 145°-153.52°, 145°-150°, 145°-155°, 150°-155°, 150°-160°, 153.52°-155°, 153.52°-160°, etc. can be selected according to actual needs, as long as the angle G between the mounting body 113 and the second base plate 112 is within the range of 145°-160°.

[0065] See also Figures 10 to 12 , Fig.10 is a bottom view of an embodiment of the refrigeration device provided by the present application; Fig.11 yes Fig.10 Enlarged view of the middle D part; Fig.12It is a structural schematic diagram of another embodiment of the first mounting seat of the hinge mechanism provided in the present application. Next, another structure of the first mounting seat 110 is introduced in the case where the first mounting seat 110 is arranged on the fourth mounting seat 152 or the fourth mounting seat 152 and the second frame strip. When the first mounting seat 110 is arranged on the fourth mounting seat 152 or the fourth mounting seat 152 and the second frame strip, the second mounting seat 120 is arranged on the mounting groove 301 corresponding to the first mounting seat 110 of the door body 300. The first mounting seat 110 includes a first bottom plate 111 and a second bottom plate 112 connected to the first bottom plate 111. The first bottom plate 111 is used to set the first mounting seat 110 on the fourth mounting seat 152 or the fourth mounting seat 152 and the second frame strip. The second bottom plate 112 has a first side 1121 and a second side 1122 arranged opposite to each other. The second side 1122 of the second bottom plate 112 is formed with a mounting body 113. The second bottom plate 112 and the mounting body 113 are used to shield at least part of the hinge assembly 130 and at least part of the second mounting seat 120 when the door body 300 is in a closed state relative to the box body 200. When the door body 300 is opened to a maximum angle relative to the box body 200, the distance between the first side 1121 and the second mounting seat 120 is greater than the distance between the second side 1122 and the second mounting seat 120. A third avoidance space 1132 is formed between the mounting body 113 and the box body 200 on one side facing the box body 200. The third avoidance space 1132 is used to avoid the hinge assembly 130 when the door body 300 is in a closed state relative to the box body 200, so as to avoid interference between the hinge assembly 130 and the first mounting seat 110. It should be noted that, when the door body 300 is in a closed state relative to the box body 200, the first connecting rod 131 protrudes toward the box body 200 on the side away from the first avoidance space 131a, and a third avoidance space 1132 is formed between the side of the mounting body 113 facing the box body 200 and the box body 200, which can prevent the first connecting rod 131 from interfering with the first mounting seat 110 when the door body 300 is in a closed state relative to the box body 200.

[0066] In some embodiments, the hinge mechanism 100 further includes a plurality of second connecting components 142. The mounting body 113 has a third axial hole 113a and a fourth axial hole 113b. The third axial hole 113a is located on a side of the fourth axial hole 113b that is close to the box body 200. It is understandable that when the door body 300 is opened to a maximum angle relative to the box body 200, the distance between the third axial hole 113a and the second mounting seat 120 is greater than the distance between the fourth axial hole 113b and the second mounting seat 120. One end of the first connecting rod 131 is hinged to the mounting body 113 by cooperating with the third axial hole 113a through the second connecting component 142. One end of the third connecting rod 133 is hinged to the mounting body 113 by cooperating with the fourth axial hole 113b through the second connecting component 142.

[0067] In some embodiments, the second connecting assembly 142 includes a connecting member 1421 and a buffer member 1422. The buffer member 1422 is sleeved on the connecting member 1421. One end of the first connecting rod 131 has a fifth axial hole 131b adapted to the third axial hole 113a of the mounting body 113. One end of the third connecting rod 133 has a sixth axial hole 133b adapted to the fourth axial hole 113b of the mounting body 113.

[0068] When the second connecting assembly 142 is used to hinge one end of the first connecting rod 131 to the mounting body 113, the connecting member 1421 is inserted into the fifth shaft hole 131b and the third shaft hole 113a, the buffer member 1422 is disposed between the first connecting rod 131 and the mounting body 113, and one end of the first connecting rod 131 can rotate around the connecting member 1421. When the second connecting assembly 142 is used to hinge one end of the third connecting rod 133 to the mounting body 113, the connecting member 1421 is inserted into the sixth shaft hole 133b and the fourth shaft hole 113b, the buffer member 1422 is disposed between the third connecting rod 133 and the mounting body 113, and one end of the third connecting rod 133 can rotate around the connecting member 1421.

[0069] The buffer members 1422 arranged between the first link 131 and the mounting body 113 and between the third link 133 and the mounting body 113 respectively support the first link 131 and the third link 133, and can form a certain gap between the first link 131 and the mounting body 113 and between the third link 133 and the mounting body 113, thereby reducing the friction between the first link 131 and the mounting body 113 and between the third link 133 and the mounting body 113, thereby improving the smoothness of the movement of the hinge mechanism 100 and reducing the occurrence of sticking.

[0070] The buffer 1422 between the first link 131 and the mounting body 113 may be integrally formed with the first link 131 or the mounting body 113, or the buffer 1422 between the first link 131 and the mounting body 113 may be detachably disposed between the first link 131 and the mounting body 113. The buffer 1422 between the third link 133 and the mounting body 113 may be integrally formed with the third link 133 or the mounting body 113, or the buffer 1422 between the third link 133 and the mounting body 113 may be detachably disposed between the third link 133 and the mounting body 113.

[0071] In some embodiments, please refer to Figures 4 to 5The hinge mechanism 100 further includes a fixing assembly 160. The fixing assembly 160 is disposed on the third mounting seat 151 or the side of the third mounting seat 151 and the first frame strip 211 facing away from the first mounting seat 110, and / or, is disposed on the fourth mounting seat 152 or the side of the fourth mounting seat 152 and the second frame strip facing away from the first mounting seat 110. The fixing assembly 160 is connected to the first mounting seat 110 to increase the bearing capacity of the first mounting seat 110.

[0072] It can be understood that when the third mounting seat 151 is embedded in the foam layer of the first frame strip 211, the fixing assembly 160 is arranged on the side of the third mounting seat 151 facing away from the door body 300, and the first mounting seat 110, the first frame strip 211, the third mounting seat 151 and the fixing assembly 160 have mutually matching mounting holes, and the first mounting seat 110, the first frame strip 211, the third mounting seat 151 and the fixing assembly 160 are fixed together by matching the mounting holes with the mounting components. When the third mounting seat 151 is arranged at the edge of the first frame strip 211 facing the storage chamber 200a, the fixing assembly 160 is arranged on the side of the third mounting seat 151 facing away from the door body 300, and the first mounting seat 110, the third mounting seat 151 and the fixing assembly 160 have mutually matching mounting holes, and the first mounting seat 110, the third mounting seat 151 and the fixing assembly 160 are fixed together by matching the mounting holes with the mounting components. When the fourth mounting seat 152 is embedded in the foam layer of the second frame strip, the fixing assembly 160 is arranged on the side of the fourth mounting seat 152 facing away from the door body 300, and the first mounting seat 110, the second frame strip, the third mounting seat 151 and the fixing assembly 160 have mutually matching mounting holes, and the first mounting seat 110, the second frame strip, the third mounting seat 151 and the fixing assembly 160 are fixed together by matching the mounting holes with the mounting components. When the fourth mounting seat 152 is arranged on the edge of the second frame strip facing the storage chamber 200a, the fixing assembly 160 is arranged on the side of the fourth mounting seat 152 facing away from the door body 300, and the first mounting seat 110, the third mounting seat 151 and the fixing assembly 160 have mutually matching mounting holes, and the first mounting seat 110, the third mounting seat 151 and the fixing assembly 160 are fixed together by matching the mounting holes with the mounting components. The mounting components can be screws, rivets, studs or bolts, but are not limited thereto.

[0073] The fixing assembly 160 supports the first mounting seat 110 to increase the bearing capacity of the first mounting seat 110. The setting of the fixing assembly 160 improves the bearing capacity of the first mounting seat 110, thereby further improving the bearing capacity of the hinge mechanism 100 and increasing the connection strength of the hinge mechanism 100 with the door body 300, preventing the hinge mechanism 100 from collapsing and deforming, and preventing the hinge mechanism 100 from tilting or sinking relative to the box body 200 due to insufficient bearing capacity. The present application does not limit the specific structure of the fixing assembly 160. The fixing assembly 160 only needs to support and fix the first mounting seat 110 and improve the bearing capacity of the hinge mechanism 100.

[0074] In some embodiments, the hinge mechanism 100 further includes a plurality of third connecting components 143, and the third connecting components 143 include a first shaft segment 1431 and a second shaft segment 1432. The second mounting seat 120 is formed with a first fixing column 121 and a second fixing column 122. When the door body 300 is opened to a maximum angle relative to the box body 200, the distance between the first fixing column 121 and the first mounting seat 110 is smaller than the distance between the second fixing column 122 and the first mounting seat 110. The other end of the second connecting rod 132 corresponds to the first fixing column 121, the first shaft 1431 of the third connecting component 143 is inserted into the first fixing column 121, and the other end of the second connecting rod 132 is sleeved on the second shaft segment 1432, and the other end of the second connecting rod 132 can rotate around the second shaft segment 1432. The other end of the fourth connecting rod 134 corresponds to the second fixing column 122 , the first shaft section 1431 of the third connecting assembly 143 is inserted into the second fixing column 122 , and the other end of the fourth connecting rod 134 is sleeved on the second shaft section 1432 , and the other end of the fourth connecting rod 134 can rotate around the second shaft section 1432 .

[0075] The arrangement of the first fixing column 121, the second fixing column 122 and the buffer member 1422 of the second connecting assembly 142 can make the line connecting the hinge point of the hinge assembly 130 at the first mounting seat 110 and the hinge point of the second mounting seat 120 parallel to the plane where the top of the refrigeration equipment 1000 is located, that is, the hinge point of the hinge assembly 130 at the first mounting seat 110 and the hinge point of the second mounting seat 120 are at the same height, thereby preventing the door body 300 from tilting or sinking relative to the box body 200.

[0076] In some embodiments, the third connecting assembly 143 further includes an adjusting portion 1433, which is disposed at the end of the second shaft segment 1432 away from the first shaft segment 1431. It is understandable that the adjusting portion 1433, the second shaft segment 1432 and the first shaft segment 1431 of the third connecting assembly 143 are connected in sequence. The outer diameters of the second shaft segment 1432 and the first shaft segment 1431 are both smaller than the outer diameter of the adjusting portion 1433. The tightness of the connection between the first shaft segment 1431 and the first fixing column 121 and / or the second fixing column 122 can be adjusted by the adjusting portion 1433, which can prevent the second connecting rod 132 and / or the fourth connecting rod 134 from being separated from the second mounting seat 120 on the one hand, and prevent the second connecting rod 132 and / or the fourth connecting rod 134 from being unable to rotate due to being hinged too tightly on the other hand.

[0077] In some embodiments, the end surface of the adjustment portion 1433 away from the second shaft segment 1432 has an adjustment groove, and the present embodiment does not limit the shape of the adjustment groove. For example, the end surface of the adjustment portion 1433 away from the second shaft segment 1432 has an adjustment groove adapted to a cross screwdriver, or has an adjustment groove adapted to a flat screwdriver, or has an adjustment groove compatible with a cross screwdriver and a flat screwdriver, so that the third connecting component 143 can be adjusted by a cross screwdriver and / or a flat screwdriver. In other embodiments, the adjustment groove of the adjustment portion 1433 away from the second shaft segment 1432 can be a hexagonal groove or an octagonal groove, but is not limited thereto. The adjustment groove should have a certain depth to prevent the screwdriver from slipping out of the adjustment groove during the adjustment process of the third connecting component 143, thereby improving the reliability of the adjustment. In other embodiments, the outer shape of the adjustment portion 1433 can also be a regular hexagonal prism, similar to a bolt or a nut, and the cross section of the adjustment portion 1433 is a regular hexagon, and the third connecting component 143 can be adjusted by a wrench.

[0078] In some embodiments, the hinge mechanism 100 further includes a fourth connecting component 144. The other end of the first connecting rod 131 is hinged to one end of the second connecting rod 132 through the fourth connecting component 144. The other end of the third connecting rod 133 is hinged to one end of the fourth connecting rod 134 through the fourth connecting component 144. The fourth connecting component 144 can be a rivet or a pin, but is not limited thereto.

[0079] In some embodiments, the first mounting base 110 is used to be disposed on the top of the box body 200 and / or the bottom of the box body 200. The second mounting base 120 is used to be disposed on the top of the door body 300 and / or the bottom of the door body 300. The top of the door body 300 can be an end plate 302 of the door body 300 close to the top of the refrigeration device 1000, and the bottom of the door body 300 can be an end plate 302 of the door body 300 close to the bottom of the refrigeration device 1000.

[0080] One end of the first connecting rod 131 is hinged to the first mounting seat 110, and the other end is hinged to one end of the second connecting rod 132. The other end of the second connecting rod 132 is hinged to the second mounting seat 120. One end of the third connecting rod 133 is hinged to the first mounting seat 110, and the other end is hinged to one end of the fourth connecting rod 134. The other end of the fourth connecting rod 134 is hinged to the second mounting seat 120, and the second connecting rod 132 is also hinged to the third connecting rod 133. The first connecting rod 131 is arranged in an arc shape to form a first avoidance space 131a on a side close to the third connecting rod 133. The first avoidance space 131a is used to avoid the third connecting rod 133. The first avoidance space 131a formed by the first connecting rod 131 can be used to avoid the third connecting rod 133 during the process of the door body 300 opening relative to the box body 200, so that the first connecting rod 131 will not interfere with the third connecting rod 133 during the process of the door body 300 opening relative to the box body 200.
