[0038] Combination Figure 1-6 As shown, the embodiment of the present disclosure provides a hinge assembly for refrigeration equipment, including: a first connection part 100, a connection shaft 200, a second connection part 300 and a limit part 400. The connection shaft 200 is arranged at the inner side of the first connection part 100 and is rotatably connected to the first connection part 100. The outer peripheral wall of the connection shaft 200 is provided with a plurality of clamping parts 210, and the plurality of clamping parts 210 are arranged along the axial direction of the connection shaft 200; the second connection part 300 is movably sleeved on the outer side of the connection shaft 200 and can move along the axial direction of the connection shaft 200; the limit part 400 is detachably clamped in the clamping part 210 corresponding to the current position of the second connection part 300 to limit the movement of the second connection part 300.

[0039] The hinge assembly for refrigeration equipment provided by the embodiment of the present disclosure is adopted, and the first connecting part 100 is connected to the box body of the refrigeration equipment, and the second connecting part 300 is connected to the door body of the refrigeration equipment. Since the second connecting part 300 is movably sleeved on the connecting shaft 200 inside the first connecting part 100, the connecting shaft 200 can rotate relative to the first connecting part 100, so that the first connecting part 100 can rotate relative to the second connecting part 300, thereby realizing the rotatable connection between the door body and the box body of the refrigeration equipment. In the case where it is necessary to adjust the left and right unevenness of the door body, the limiting part 400 is disassembled, and the second connecting part 300 is driven to move along the axial direction of the connecting shaft 200, so as to adjust the left and right position of the door body relative to the box body. After the adjustment is completed, the limiting part 400 is clamped in the clamping part 210 corresponding to the second connecting part 300, so that the second connecting part 300 is positioned relative to the first connecting part 100. By cooperating the limiting portion 400 with the multiple clamping portions 210 on the outer peripheral wall of the connecting shaft 200, the hinge assembly for the refrigeration equipment can be adapted to the use of various refrigeration equipment, thereby improving the connection stability of the door body relative to the box body in the adjusted refrigeration equipment.

[0040] It can be understood that the left and right direction of the door body refers to the left and right direction of the user when the user faces the front wall of the refrigeration device.

[0041] Optionally, the second connecting part 300 includes: an assembly plate 310, a first connecting arm 320 and a second connecting arm 330. A first assembly hole 311 is provided on the side wall of the assembly plate 310; one end of the first connecting arm 320 is connected to one side of the assembly plate 310, and the other end extends into the inner side of the first connecting part 100 and is sleeved on the outer side of the connecting shaft 200; one end of the second connecting arm 330 is connected to the other side of the assembly plate 310, and the other end extends into the inner side of the first connecting part 100 and is sleeved on the outer side of the connecting shaft 200; wherein, a plurality of clamping parts 210 are provided in the outer peripheral wall of the connecting shaft 200 corresponding to the area where the first connecting arm 320 and the second connecting arm 330 are sleeved, and the limiting part 400 is detachably clamped in the clamping parts 210 corresponding to the first connecting arm 320 and the second connecting arm 330, thereby simultaneously limiting the movement of the first connecting arm 320 and the second connecting arm 330. In this way, the second connection part 300 is divided into the assembly plate 310, the first connection arm 320 and the second connection arm 330, and is connected to the door body of the refrigeration equipment by using the first assembly hole 311 on the assembly plate 310, and the first connection arm 320 and the second connection arm 330 are respectively sleeved on different areas outside the connection shaft 200. Since the first connection arm 320 and the second connection arm 330 are respectively connected to the two opposite sides of the assembly plate 310, the assembly plate 310 is connected to the connection shaft 200 through the first connection arm 320 and the second connection arm 330, the connection stability between the assembly plate 310 and the connection shaft 200 is improved, and the first connection part 100 is connected to the box body through the assembly plate 310 and the door body, thereby improving the stability of the rotational connection between the door body and the box body. A plurality of clamping portions 210 are provided on the outer peripheral wall of the connecting shaft 200 at positions corresponding to the first connecting arm 320 and the second connecting arm 330. The first connecting arm 320 and the second connecting arm 330 are limited by the limiting portion 400 clamped in the clamping portion 210, thereby further improving the stability of the second connecting portion 300 after movable adjustment, and further improving the stability of the door body after adjustment to make the left and right sides uneven.

[0042] Exemplarily, when the assembly plate 310 is assembled with the door body, bolts are inserted into the door body through the first assembly holes 311 to complete the installation of the door body and the assembly plate 310. After the assembly is completed, the side wall of the assembly plate 310 is attached to the side wall of the door body.

[0043] Optionally, the assembly plate 310 is a rectangular plate-like structure, and the first connecting arm 320 and the second connecting arm 330 are both plate-like structures extending toward the inner side of the first connecting portion 100 along the opposite sides of the assembly plate 310. In this way, the assembly plate 310 with a rectangular plate-like structure can be better adapted to the installation of the door body, so that the side wall of the assembly plate 310 is more closely attached to the side wall of the door body, reducing the gap after assembly. When the first connecting arm 320 and the second connecting arm 330 with a plate-like structure are sleeved on the connecting shaft 200, a larger adjustment space can be reserved, so that the assembly plate 310, the first connecting arm 320 and the second connecting arm 330 can be adjusted in a wider range in the left-right direction, so that the adjustment amount of the door body is larger, and the unevenness of the door body can be better adjusted.

[0044] Optionally, the first connecting arm 320 and the second connecting arm 330 are parallel to each other. In this way, the force on the first connecting arm 320 and the second connecting arm 330 is more uniform, and the connection stability between the assembly plate 310 and the connecting shaft 200 is improved.

[0045] Specifically, shaft holes are provided at positions of the first connecting arm 320 and the second connecting arm 330 corresponding to the connecting shaft 200 , and the connecting shaft 200 passes through the shaft holes on the first connecting arm 320 and the second connecting arm 330 in sequence.

[0046] Combination Figure 1 and Figure 3 As shown, in one embodiment, the clamping portion 210 is an annular clamping groove, and the limiting portion 400 includes: a first clamping spring 410 and a second clamping spring 420. The first clamping spring 410 is detachably clamped in the annular clamping groove corresponding to the first connecting arm 320; the second clamping spring 420 is detachably clamped in the annular clamping groove corresponding to the second connecting arm 330. In this way, the clamping portion 210 is set as an annular clamping groove, and the limiting portion 400 is divided into the first clamping spring 410 and the second clamping spring 420. The first clamping spring 410 and the second clamping spring 420 cooperate with each other and are clamped in the annular clamping groove corresponding to the first connecting arm 320 and the annular clamping groove corresponding to the second connecting arm 330, respectively, and at the same time, the activities of the first connecting arm 320 and the second connecting arm 330 are restricted, thereby improving the stability of the connection between the first connecting arm 320 and the second connecting arm 330 and the connecting shaft 200, thereby improving the stability of the connection between the second connecting portion 300 and the connecting shaft 200.

[0047] Optionally, the first clip spring 410 and the second clip spring 420 both have openings, and the first clip spring 410 and the second clip spring 420 are both clamped in the corresponding annular clamping groove through their openings. In this way, the installation and removal of the first clip spring 410 and the second clip spring 420 are facilitated, and the efficiency of adjusting the second connecting portion 300 relative to the first connecting portion 100 in the left-right direction is improved.

[0048] Optionally, the width of the opening of the first clamping spring 410 and the second clamping spring 420 is smaller than the diameter of the connecting shaft 200, and greater than or equal to two-thirds of the diameter of the connecting shaft 200. In this way, the first clamping spring 410 and the second clamping spring 420 can be clamped in the corresponding annular clamping groove by using their own elasticity, and the first clamping spring 410 and the second clamping spring 420 are not easy to fall off after being clamped, thereby improving the stability of the first connecting arm 320 and the second connecting arm 330.

[0049] Specifically, the width of the opening of the first clip spring 410 and the second clip spring 420 is equal to two-thirds of the diameter of the connecting shaft 200. In this way, the width of the opening of the first clip spring 410 and the second clip spring 420 is set to be equal to two-thirds of the diameter of the connecting shaft 200, so that the first clip spring 410 and the second clip spring 420 can be smoothly clamped in the corresponding annular clamping groove by using their own elasticity, and the first clip spring 410 and the second clip spring 420 are prevented from being damaged due to excessive deformation.

[0050] Combination Figure 4 and Figure 5 As shown, in another embodiment, the clamping portion 210 is a clamping hole, and the limiting portion 400 includes: a first latch 430 and a second latch 440. The first latch 430 is detachably inserted into the clamping hole corresponding to the first connecting arm 320; the second latch 440 is detachably inserted into the clamping hole corresponding to the second connecting arm 330. In this way, the clamping portion 210 is set as a clamping hole, and the limiting portion 400 is divided into the first latch 430 and the second latch 440. The first latch 430 and the second latch 440 cooperate and are respectively inserted into the clamping holes corresponding to the first connecting arm 320 and the second connecting arm 330, and at the same time, the activities of the first connecting arm 320 and the second connecting arm 330 are restricted, thereby improving the stability of the connection between the first connecting arm 320 and the second connecting arm 330 and the connecting shaft 200, thereby improving the stability of the connection between the second connecting portion 300 and the connecting shaft 200.

[0051] Optionally, the plurality of clamping parts 210 provided in the area of ​​the outer peripheral wall of the connecting shaft 200 corresponding to the sleeve of the first connecting arm 320, and the plurality of clamping parts 210 provided in the area of ​​the outer peripheral wall of the connecting shaft 200 corresponding to the sleeve of the second connecting arm 330 are evenly arranged along the axial direction of the connecting shaft 200. In this way, since the limiting part 400 is divided into a first clamping spring 410 and a second clamping spring 420, the first connecting arm 320 is limited by the first clamping spring 410, and the second connecting arm 330 is limited by the second clamping spring 420, a plurality of evenly distributed clamping parts 210 are provided in the area of ​​the outer peripheral wall of the connecting shaft 200 corresponding to the sleeve of the first connecting arm 320 and the second connecting arm 330. When the second connecting part 300 is adjusted in the left and right directions relative to the first connecting part 100, the first clamping spring 410 and the second clamping spring 420 can change the clamping part 210 according to the movable adjustment of the first connecting arm 320 and the second connecting arm 330, so that the fixation of the first connecting arm 320 and the second connecting arm 330 is more stable.

[0052] Specifically, the multiple clamping parts 210 corresponding to the area where the first connecting arm 320 is sleeved are evenly distributed along the axial direction of the connecting shaft 200, and the multiple clamping parts 210 corresponding to the area where the second connecting arm 330 is sleeved are also evenly distributed along the axial direction of the connecting shaft 200.

[0053] Optionally, a scale bar is provided on the peripheral wall of the connecting shaft 200 corresponding to the area where the first connecting arm 320 is sleeved, and the multiple clamping parts 210 in the area are evenly distributed along the scale bar. In this way, the setting of the scale bar can indicate the distance between two adjacent or separated clamping parts 210. When adjusting the left and right unevenness of the door body, the user can measure the width value of the left and right protrusions of the door body, and then adjust the first connecting arm 320 to the position of the target clamping part 210 according to the position of the target clamping part 210 indicated by the scale bar. After the first connecting arm 320 is adjusted to the position of the target clamping part 210, the second connecting arm 330 will also move with the first connecting arm 320 to the target position to be adjusted, thereby improving the adjustment efficiency of the left and right unevenness of the door body.

[0054] Optionally, the first connecting arm 320 is provided with a first boss 321 at a position where it is sleeved on the outer side of the connecting shaft 200, and when the limiting portion 400 forms a restriction on the movement of the first connecting arm 320, the first boss 321 abuts against the limiting portion 400; the second connecting arm 330 is provided with a second boss 331 at a position where it is sleeved on the outer side of the connecting shaft 200, and when the limiting portion 400 forms a restriction on the movement of the second connecting arm 330, the second boss 331 abuts against the limiting portion 400. In this way, the first boss 321 can abut against the first clamping spring 410 more closely, thereby improving the stability of the first clamping spring 410 limiting the first connecting arm 320. The second boss 331 can abut against the second clamping spring 420 more closely, thereby improving the stability of the second clamping spring 420 limiting the second connecting arm 330. Through the cooperation of the first boss 321, the second boss 331 and the first retaining spring 410, the second retaining spring 420, the stability of the limiting of the first connecting arm 320 and the second connecting arm 330 is further improved, so that the stability of the connection between the adjusted first connecting arm 320 and the second connecting arm 330 and the connecting shaft 200 is stronger.

[0055] It can be understood that the axial distance between the clamping portion 210 of the first clamping spring 410 and the clamping portion 210 of the second clamping spring 420 along the connecting shaft 200 is equal to the axial distance between the opposite side walls of the first boss 321 and the second boss 331 along the connecting shaft 200, so that the cooperation between the first clamping spring 410 and the second clamping spring 420 can form a stable limit for the first connecting arm 320 and the second connecting arm 330.

[0056] Optionally, the first connection part 100 includes: a mounting plate 110 and a support arm 120. The side wall of the mounting plate 110 is provided with a second assembly hole 111; two support arms 120 are provided, and the two support arms 120 are respectively connected to the two opposite sides of the mounting plate 110, and both protrude along the plane where the mounting plate 110 is located. The connecting shaft 200 is arranged between the two support arms 120, and the two ends of the connecting shaft 200 respectively penetrate the two support arms 120 and are rotatably connected to the two support arms 120. In this way, the first connection part 100 is divided into the mounting plate 110 and the two support arms 120, and is assembled and connected with the box body of the refrigeration equipment through the mounting plate 110. The two support arms 120 are respectively protruded along the two opposite sides of the mounting plate 110, and an installation space is formed between the two support arms 120. The connecting shaft 200 is rotatably installed between the two support arms 120, which improves the stability of the rotational connection between the connecting shaft 200 and the first connection part 100, thereby improving the stability of the rotational connection between the first connection part 100 and the second connection part 300.

[0057] Optionally, the mounting plate 110 is a rectangular plate-like structure, and the two arms 120 are plate-like structures protruding along the long sides of the mounting plate 110. In this way, the mounting plate 110 with a rectangular plate-like structure can be better installed with the box, and the side wall of the mounting plate 110 is attached to the side wall of the box, which improves the connection stability between the mounting plate 110 and the box. Both arms 120 are plate-like structures, which can increase the volume of the installation space between the two arms 120, facilitate the installation of the connecting shaft 200, and the extension of the first connecting arm 320 and the second connecting arm 330.

[0058] Optionally, the upper ends of the two supporting arms 120 protrude from the upper side of the mounting plate 110 along the long sides of both sides of the mounting plate 110. In this way, the mounting plate 110 is prevented from interfering with the movement of the first connecting arm 320 and the second connecting arm 330.

[0059] Specifically, the two supporting arms 120 are perpendicular to the mounting plate 110. In this way, the forces on the two supporting arms 120 are more uniform, and the supporting stability of the two supporting arms 120 is improved.

[0060] Optionally, a guide rod 500 is further provided on the inner side of the two support arms 120, one end of the second connection part 300 is movably sleeved on the outer side of the guide rod 500, and guide grooves 121 are provided at the positions of the two support arms 120 corresponding to the two ends of the guide rod 500, and the two ends of the guide rod 500 are respectively movably embedded in the corresponding guide grooves 121.
