[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides a hinge assembly for a refrigeration device, comprising: a mounting plate 100, a first hinge plate 200 and a second hinge plate 300. The mounting plate 100 is provided with a first guide structure 110 arranged along the front-to-back direction of the box of the refrigeration device; the first hinge plate 200 is slidably arranged above the mounting plate 100, the first hinge plate 200 is provided with a second guide structure 210 arranged along the front-to-back direction of the box, the first guide structure 110 is slidably connected with the second guide structure 210, so that the first hinge plate 200 slides along the front-to-back direction of the box during sliding adjustment; the second hinge plate 300 is slidably arranged above the first hinge plate 200, the second hinge plate 300 is provided with a third guide structure 310, the third guide structure 310 is arranged in a horizontal direction parallel to the front side wall of the box, the first hinge plate 200 is provided with a fourth guide structure 220, the third guide structure 310 is slidably connected with the fourth guide structure 220, so that the second hinge plate 300 slides in a horizontal direction parallel to the front side wall of the box during sliding adjustment.

[0041] By using the hinge assembly for refrigeration equipment provided by the embodiment of the present disclosure, when it is necessary to adjust the position of the door body relative to the front-to-back direction of the box body, the first hinge plate 200 is slid relative to the mounting plate 100 in the front-to-back direction, and under the action of the first guide structure 110 and the second guide structure 210, the sliding stability of the first hinge plate 200 is higher. When it is necessary to adjust the position of the door body relative to the left-to-right direction of the box body, the second hinge plate 300 is slid relative to the mounting plate 100 in the left-to-right direction, and under the action of the third guide structure 310 and the fourth guide structure 220, the sliding stability of the second hinge plate 300 is higher. The first hinge plate 200 and the second hinge plate 300 can be slid relative to the mounting plate 100 in the front-to-back and left-to-right directions, and can cope with the adjustment of various door body misalignment conditions. Through the cooperation of the first guide structure 110, the second guide structure 210, the third guide structure 310 and the fourth guide structure 220, the door body is more stable during adjustment and the risk of displacement is reduced.

[0042] Optionally, the first guide structure 110 is disposed on the upper side wall of the mounting plate 100, the second guide structure 210 is disposed on the inner side of the first hinge, and the first guide structure 110 is embedded in the second guide structure 210 for sliding connection. In this way, by embedding the first guide structure 110 in the second guide structure 210 for sliding connection, the connection stability of the first guide structure 110 and the second guide structure 210 can be improved, and the first hinge plate 200 can be guided more stably by the first guide structure 110 and the second guide structure 210.

[0043] Optionally, the third guide structure 310 is disposed on the inner side of the second hinge plate 300, the fourth guide structure 220 is disposed on the upper side of the first hinge plate 200, and the fourth guide structure 220 is embedded in the third guide structure 310 for sliding connection. In this way, by embedding the fourth guide structure 220 in the third guide structure 310 for sliding connection, the connection stability of the third guide structure 310 and the fourth guide structure 220 can be improved, and the second hinge plate 300 can be guided more stably by the third guide structure 310 and the fourth guide structure 220.

[0044] Optionally, the first guide structure 110 is a guide rail, the second guide structure 210 is a slide groove, the guide rail is embedded in the slide groove, and the guide rail and the slide groove are slidably connected; the third guide structure 310 is a guide groove, and the fourth guide structure 220 is a bump, the bump is embedded in the guide groove, and the bump is slidably connected to the guide groove. In this way, the first guide structure 110 is set as a guide rail, and the second guide structure 210 is set as a slide groove, and the guide rail is embedded in the slide groove to form a more stable guide, further improving the sliding stability of the first hinge plate 200. The third guide structure 310 is set as a guide groove, and the fourth guide structure 220 is set as a bump, and the bump is embedded in the guide groove to form a more stable guide, further improving the sliding stability of the second hinge plate 300.

[0045] Specifically, the guide rail is a long strip protrusion structure arranged along the front and rear direction of the box body, and the slide groove is a long strip groove structure arranged along the front and rear direction of the box body. The side walls corresponding to the long sides of the guide rail are slidably connected with the inner walls corresponding to the long sides of the slide groove.

[0046] Optionally, the length of the slide groove is greater than the length of the guide rail. In this way, there is a sliding margin between the two ends of the guide rail and the two ends of the slide groove, and when the first hinge plate 200 is slidably adjusted, the slide groove can slide relative to the guide rail.

[0047] Specifically, the guide groove is a rectangular groove structure, and the long side of the guide groove is arranged in a horizontal direction parallel to the front side wall of the box body.

[0048] Optionally, the length of the guide groove is greater than the thickness of the projection along the length direction of the guide groove. In this way, the projection has a sliding margin in the guide groove, and when the second hinge plate 300 is slidably adjusted, the guide groove can slide relative to the projection.

[0049] It can be understood that the side wall of the box body facing the door body is the front side wall of the box body, and the side wall of the box body facing away from the door body is the rear side wall of the box body. The front and rear direction of the box body refers to the direction from the front side wall to the rear side wall of the box body.

[0050] Alternatively, if Figure 2 As shown, a first bolt groove 230 is provided inside the first hinge plate 200, and a first threaded hole 120 is provided on the upper side wall of the mounting plate 100 at a position corresponding to the first bolt groove 230. One end of the first screw rod 130 passes through the first bolt groove 230 and extends into the first threaded hole 120 to install the first hinge plate 200. The first bolt groove 230 is provided along the front-to-back direction of the box body, and the length of the first bolt groove 230 along the front-to-back direction of the box body is greater than the diameter of the first screw rod 130. In this way, the first hinge plate 200 is fixed to the mounting plate 100 by the first bolt passing through the first bolt groove 230 and extending into the first threaded hole 120. Since the first hinge plate 200 can be slidably adjusted relative to the mounting plate 100, the length of the first bolt groove 230 is set to be greater than the diameter of the first bolt, so that the first bolt has a movable margin. When the first hinge plate 200 is slidably adjusted forward and backward, the first bolt groove 230 can move forward and backward relative to the first bolt, and the first hinge plate 200 can still be fixed by the first bolt after adjustment. The first bolt groove 230 is arranged along the front-rear direction of the box body, so that the first bolt groove 230 also has a guiding function.

[0051] Specifically, a thread is disposed on the outer peripheral wall of the first bolt, and the end portion of the first bolt extending into the first threaded hole 120 is fixed by threaded engagement.

[0052] Optionally, three first bolt slots 230 are provided inside the first hinge plate 200, first threaded holes 120 are provided at positions corresponding to the three first bolt slots 230 on the upper side wall of the mounting plate 100, and three first bolts are also provided, and each first bolt passes through the corresponding first bolt slot 230 and extends into the corresponding first threaded hole 120. In this way,

[0053] Specifically, two of the three first bolt slots 230 are arranged on one side of the second guide structure 210 in the width direction along the length direction of the second guide structure 210, and the other first bolt slot 230 is arranged on the other side of the second guide structure 210 in the width direction. In this way, when the first hinge plate 200 is fixed by three first bolts passing through the corresponding first bolt slots 230 and extending into the corresponding first threaded holes 120, a triangular fixing area is formed, which improves the stability of the first hinge plate 200 and prevents the first hinge plate 200 from being offset due to force.

[0054] Alternatively, if Figure 3 and Figure 4 As shown, the hinge assembly for refrigeration equipment further includes: a first adjusting button 140. Part of the first adjusting button 140 is movably embedded in the inner side of the first hinge plate 200, and the rest of the first adjusting button 140 extends into the inner side of the mounting plate 100; wherein, when the first adjusting button 140 rotates, the first hinge plate 200 can be driven to slide along the front-to-back direction of the box. In this way, the first hinge plate 200 can be driven to slide along the front-to-back direction of the box by rotating the first adjusting button 140, and the sliding position of the first hinge plate 200 can be adjusted more finely, thereby more accurately adjusting the front-to-back distance between the door body and the box body.

[0055] Optionally, the first adjustment button 140 includes: a first button plate 141 and a first shaft 142. The first button plate 141 is movably embedded in the inner side of the first hinge plate 200; one end of the first shaft 142 is fixedly connected to the first button plate 141, and the other end extends into the inner side of the mounting plate 100; wherein, along the radial direction of the first button plate 141, there is a first distance between the axis of the first shaft 142 and the axis of the first button plate 141. In this way, since the first hinge plate 200 can slide back and forth relative to the mounting plate 100, when the first button plate 141 is driven to rotate, since the first shaft 142 extends into the mounting plate 100, there is a first distance between the axis of the first shaft 142 and the axis of the first button plate 141 in the radial direction, so the first button plate 141 performs a circular motion along the axis of the first shaft 142, thereby driving the first hinge plate 200 to slide. The adjustment method of driving the first hinge plate 200 to slide by the first button 141 performing circular motion along the first axis 142 is more precise than the traditional linear motion driving method, so that the sliding of the first hinge plate 200 relative to the mounting plate 100 is more precise, thereby more precisely adjusting the front and rear position of the door body relative to the box body, and better adjusting the front and rear unevenness of the door body.

[0056] Specifically, the diameter of the first shaft 142 is less than or equal to the radius of the first button plate 141, and greater than half of the radius of the first button plate 141; the first distance is equal to half of the radius of the first button plate 141. In this way, when the first hinge plate 200 is adjusted, the first shaft 142 plays a supporting role. Setting the diameter of the first shaft 142 to be less than or equal to the radius of the first button plate 141, and greater than half of the radius of the first button plate 141, can ensure the support strength of the first shaft 142 and reduce the risk of the first shaft 142 breaking when rotating. Setting the first distance to be equal to half of the radius of the first button plate 141 can ensure the range of motion of the first button plate 141 relative to the first shaft 142, and ensure the fine driving of the first hinge plate 200 while ensuring the adjustment efficiency of the first hinge plate 200.

[0057] Specifically, a first through groove 240 is provided on the inner side of the first hinge plate 200, the first button plate 141 is located in the first through groove 240, and the outer peripheral wall portion of the first button plate 141 abuts against the first through groove 240. In this way, when the first button plate 141 rotates, the first button plate 141 performs a circular motion along the axis of the first shaft 142, and the position where the outer peripheral wall of the first button plate 141 abuts against the first through groove 240 applies a forward or backward thrust toward the first hinge plate 200, thereby driving the first hinge plate 200 to slide forward or backward.

[0058] Specifically, an axial hole is provided inside the mounting plate 100 , and the first shaft 142 is movably embedded in the axial hole.

[0059] Optionally, the first through-groove 240 is a rectangular groove-shaped structure, and the long side of the first through-groove 240 is perpendicular to the long side of the second guide structure 210, the length of the first through-groove 240 is greater than the diameter of the first button plate 141, and the outer peripheral wall of the first button plate 141 abuts against the inner wall corresponding to the short side of the first through-groove 240. In this way, the first button plate 141 has a rotation margin in the first through-groove 240, and when the first button plate 141 rotates, it can apply a forward or backward thrust to the inner wall of the first through-groove 240 through the outer peripheral wall, thereby driving the first hinge plate 200 to move forward or backward.

[0060] Optionally, a driving groove is provided on the upper side wall of the first button plate 141. In this way, when the first button plate 141 needs to be driven to rotate, an auxiliary tool can be inserted into the driving groove to twist the first button plate 141 to rotate.

[0061] Specifically, the driving groove is a cross-shaped groove structure. In this way, when the first button plate 141 is rotated by twisting the driving groove, the contact area between the driving groove and the auxiliary tool is increased, which is convenient for twisting.

[0062] Exemplarily, the first button plate 141 can be twisted by inserting a Phillips screwdriver into the driving groove. When the first button plate 141 rotates, the first shaft 142 rotates relative to the shaft hole on the inner side of the mounting plate 100. The first button plate 141 performs a circular motion along the axis of the first shaft 142 under the action of the first shaft 142. The position where the outer peripheral wall of the first button plate 141 abuts against the first through groove 240 will apply a forward or backward thrust, driving the first hinge plate 200 to slide forward or backward.

[0063] Alternatively, if Figure 2 As shown, a second bolt groove 320 is provided inside the second hinge plate 300, and a second threaded hole 250 is provided at a position corresponding to the second bolt groove 320 on the upper side wall of the first hinge plate 200. One end of the second screw rod 260 passes through the second bolt groove 320 and extends into the second threaded hole 250 to install the second hinge plate 300. The second bolt groove 320 is provided in a horizontal direction parallel to the front side wall of the box body, and the length of the second bolt groove 320 in the horizontal direction parallel to the front side wall of the box body is greater than the diameter of the second screw rod 260. In this way, the second hinge plate 300 is fixed to the mounting plate 100 by the second bolt passing through the second bolt groove 320 and extending into the second threaded hole 250. Since the second hinge plate 300 can be slidably adjusted relative to the first hinge plate 200, the length of the second bolt groove 320 is set to be greater than the diameter of the second bolt, so that the second bolt has a movable margin. When the second hinge plate 300 is slidably adjusted left and right, the second bolt slot 320 can move left and right relative to the second bolt, and the second hinge plate 300 can still be fixed by the second bolt after adjustment. The second bolt slot 320 is arranged in a horizontal direction parallel to the front side wall of the box body, so that the second bolt slot 320 also has a guiding function.

[0064] Specifically, a thread is provided on the outer peripheral wall of the second bolt, and the portion of the end of the second bolt extending into the second threaded hole 250 is fixed by threaded engagement.

[0065] Alternatively, if Figure 5 and Figure 6 As shown, the hinge assembly for refrigeration equipment further includes: a second adjusting button 330. Part of the second adjusting button 330 is movably embedded in the inner side of the second hinge plate 300, and the rest of the second adjusting button 330 extends into the inner side of the first hinge plate 200; wherein, when the second adjusting button 330 is rotated, the second hinge plate 300 can be driven to slide in a horizontal direction parallel to the front side wall of the box. In this way, the second hinge plate 300 can be driven to slide in the left-right direction of the box by rotating the second adjusting button 330, and the sliding position of the second hinge plate 300 can be adjusted more finely, thereby adjusting the left-right position of the door body more accurately.

[0066] Optionally, the second adjustment button 330 includes: a second button plate 331 and a second shaft 332. The second button plate 331 is movably embedded in the inner side of the second hinge plate 300; one end of the second shaft 332 is fixedly connected to the second button plate 331, and the other end extends into the first hinge plate 200; wherein, along the radial direction of the second button plate 331, there is a second distance between the axis of the second button plate 331 and the axis of the second shaft 332. Since the second hinge plate 300 can slide left and right relative to the first hinge plate 200, when the second button plate 331 is driven to rotate, since the second shaft 332 extends into the first hinge plate 200, there is a second distance between the axis of the second button plate 331 and the axis of the second shaft 332 in the radial direction, so the second button plate 331 performs a circular motion along the second shaft 332, thereby driving the second hinge plate 300 to slide in the left and right direction. The adjustment method of driving the second hinge plate 300 to slide by the second button plate 331 performing circular motion along the second axis 332 is more precise than the traditional linear motion driving method, so that the sliding of the second hinge plate 300 relative to the first hinge plate 200 is more precise, thereby more precisely adjusting the left and right positions of the door body and better adjusting the left and right unevenness of the door body.

[0067] Specifically, the second through groove 270 is provided on the inner side of the second hinge plate 300, the second button plate 331 is located in the second through groove 270, and the outer peripheral wall of the second button plate 331 abuts against the second through groove 270. In this way, when the second button plate 331 rotates, the second button plate 331 performs a circular motion along the axis of the second shaft 332, and the position where the outer peripheral wall of the second button plate 331 abuts against the second through groove 270 applies a leftward or rightward thrust toward the second hinge plate 300, thereby driving the second hinge plate 300 to slide leftward or rightward.

[0068] Specifically, an axis hole is also provided on the inner side of the first hinge plate 200, and the second axis 332 is movably embedded in the axis hole.

[0069] Optionally, the second through-groove 270 is a rectangular groove-shaped structure, and the long side of the second through-groove 270 is perpendicular to the long side of the third guide structure 310, the length of the second through-groove 270 is greater than the diameter of the second button plate 331, and the outer peripheral wall of the second button plate 331 abuts against the inner wall corresponding to the short side of the second through-groove 270. In this way, the second button plate 331 has a rotation margin in the second through-groove 270, and when the second button plate 331 rotates, it can apply a leftward or rightward thrust to the inner wall of the second through-groove 270 through the outer peripheral wall, thereby driving the second hinge plate 300 to move leftward or rightward.

[0070] Optionally, a driving groove is also provided on the upper side wall of the second button plate 331. In this way, when the second button plate 331 needs to be driven to rotate, an auxiliary tool can be inserted into the driving groove to twist the second button plate 331 to rotate.

[0071] Exemplarily, the second button plate 331 is twisted by an auxiliary tool. When the second button plate 331 rotates, the second shaft 332 rotates relative to the shaft hole on the inner side of the mounting plate 100. The second button plate 331 performs a circular motion along the axis of the second shaft 332 under the action of the second shaft 332. The position where the outer wall of the second button plate 331 abuts against the second through groove 270 will apply a thrust to the left or right, driving the second hinge plate 300 to slide to the left or right.

[0072] It can be understood that the structure and connection position of the second button plate 331 and the second shaft 332 are the same as those of the first adjusting button 140, and are not described in detail here.

[0073] Optionally, a fifth guide structure 280 is further provided on the inner side of the first hinge plate 200, and a sixth guide structure 340 is provided on the second hinge plate 300. The fifth guide structure 280 is a guide groove, and the sixth guide structure 340 is a convex block. The sixth guide structure 340 is embedded in the fifth guide structure 280 for sliding connection. In this way, by providing the cooperation of the fifth guide structure 280 and the sixth guide structure 340, the second hinge plate 300 is further guided, and when the second hinge plate 300 is slidably adjusted relative to the first hinge plate 200, the stability is higher.

[0074] Specifically, the fifth guide structure 280 is a rectangular groove-shaped structure, and the arrangement direction of the fifth guide structure 280 is consistent with the arrangement direction of the third guide structure 310 .

[0075] Alternatively, if Figure 7 As shown, the fifth guide structure 280 and the fourth guide structure 220 are respectively arranged on the left and right sides of the second adjusting button 330, and the sixth guide structure 340 and the third guide structure 310 are respectively arranged on the left and right sides of the second adjusting button 330. In this way, the second hinge plate 300 is guided on one side of the second adjusting button 330 by the cooperation of the fifth guide structure 280 and the sixth guide structure 340, and the second hinge plate 300 is guided on the other side of the second adjusting button 330 by the cooperation of the third guide structure 310 and the fourth guide structure 220, so as to form a better guiding effect. In addition, by using the cooperation structure of the guide groove and the protrusion, the second hinge plate 300 and the first hinge plate 200 form a buckling effect, which further improves the connection stability between the second hinge plate 300 and the first hinge plate 200.

[0076] Exemplarily, the front end of the first hinge plate 200 protrudes forward along the front side of the mounting plate 100, and the position where the second hinge plate 300 is slidably connected to the first hinge plate 200 is mostly located in front of the mounting plate 100. A hinge shaft is provided at one end of the second hinge plate 300, and when assembled with the refrigeration equipment, the hinge shaft is hinged to the door body of the refrigeration equipment.

[0077] Optionally, the hinge assembly for refrigeration equipment further includes: a first positioning screw 290 and a second positioning screw 350. One end of the first positioning screw 290 passes through the first hinge plate 200 and is embedded in the mounting plate 100. When the first hinge plate 200 is slidably adjusted relative to the mounting plate 100, the first positioning screw 290 is disengaged from the first hinge plate 200 and the mounting plate 100; one end of the second positioning screw 350 passes through the second hinge plate 300 and is embedded in the first hinge plate 200. When the second hinge plate 300 is slidably adjusted relative to the first hinge plate 200, the second positioning screw 350 is disengaged from the second hinge plate 300 and the first hinge plate 200. In this way, when the hinge assembly for refrigeration equipment leaves the factory, the first hinge plate 200 and the mounting plate 100 are positioned and fixed by the first positioning screw 290, and the second hinge plate 300 and the first hinge plate 200 are positioned and fixed by the second positioning screw 350, thereby improving the overall stability of the hinge assembly for refrigeration equipment. When the hinge assembly for refrigeration equipment is assembled with the refrigeration equipment, if the door body is not uneven, the first positioning screw 290 and the second positioning screw 350 do not need to be removed, and the connection stability between the door body and the box body is better. If the door body is uneven front and back or left and right, the first positioning screw 290 and / or the second positioning screw 350 can be selectively removed according to the actual situation to adjust the door body accordingly.

[0078] Specifically, screw holes are set at the positions of the first hinge plate 200 and the mounting plate 100 corresponding to the first positioning screw 290, and screw holes are also set at the positions of the second hinge plate 300 and the first hinge plate 200 corresponding to the second positioning screw 350; the first positioning screw 290 passes through the screw holes corresponding to the first hinge plate 200 and the mounting plate 100 in sequence to position and fix the first hinge plate 200 and the mounting plate 100, and the second positioning screw 350 passes through the screw holes corresponding to the second hinge plate 300 and the first hinge plate 200 in sequence to position and fix the second hinge plate 300 and the first hinge plate 200.
