Description

Technical Field

[0001] This application relates to the field of refrigeration equipment, and in particular to a leveling device and a refrigerator assembly. Background Technology

[0002] Because the ground where the refrigerator is stored is not flat, or because the flatness of the ground changes due to the long-term influence of the refrigerator's weight, the refrigerator door is not flat in the vertical, horizontal, and back-to-back directions, which can easily lead to damage to the refrigerator door.

[0003] Currently, most refrigerators are leveled by using a leveling angle at the bottom hinge. Workers use tools or their hands to rotate the leveling angle until it contacts the ground, thus adjusting the refrigerator's flatness.

[0004] Regarding the above technical solution, staff cannot adjust the height and flatness of the back of the refrigerator, and due to the refrigerator's large weight, the above leveling method is quite laborious. Summary of the Invention

[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-9 This application describes a leveling device according to an embodiment of the present application, which is used to level a refrigeration device.

[0034] Reference Figure 1 and Figure 2 According to an embodiment of this application, the leveling device includes: a base body 1 and multiple sets of adjustment components 2 mounted on the base body 1; the base body 1 is adapted to be installed at the bottom of the refrigeration equipment, and the flatness of the refrigeration equipment is adjusted by the adjustment components 2 on the base body 1. Each set of adjustment components 2 includes at least two adjustment components 2 spaced apart in the front-back direction, each adjustment component 2 is movably mounted on the base body 1, and the multiple sets of adjustment components 2 are spaced apart in the left-right direction.

[0035] It is understood that each set of adjustment components 2 includes at least two adjustment components 2 spaced apart in the front-to-back direction, so that the leveling device can adjust the flatness of the refrigeration equipment in the front-to-back direction; multiple sets of adjustment components 2 are spaced apart in the left-to-right direction, so that the leveling device can adjust the flatness of the refrigeration equipment in the left-to-right direction.

[0036] Reference Figure 2 , Figure 3 and Figure 4Each adjusting component 2 includes a support base 21, a lifting component 22, a lifting top cover 23, and an operating lever 24. The lifting top cover 23 is adapted to support the bottom wall of the refrigeration equipment. The lifting component 22 cooperates with both the support base 21 and the lifting top cover 23. The lifting component 22 moves to adjust the height between the lifting top cover 23 and the support base 21. The operating lever 24 is connected to the lifting component 22 to drive its movement. By operating the operating lever 24 of one adjusting component 2, the operator can control the movement of the lifting component 22, thereby adjusting the height between the lifting top cover 23 and the support base 21. The height of the refrigeration equipment is controlled by the lifting of the lifting top cover 23. Compared to the technical solution of lifting the refrigerator to adjust the leveling feet, the leveling method of the leveling device in this application is time-saving and labor-saving, improving the convenience of the leveling operation.

[0037] According to an embodiment of this application, a leveling device is provided at the bottom of a refrigeration device. Multiple sets of adjustment components 2 are arranged at the bottom, each set including at least two adjustment components 2 spaced apart in the front-to-back direction. This allows the leveling device to adjust the flatness of the refrigeration device in the front-to-back direction. The multiple sets of adjustment components 2 are also spaced apart in the left-to-right direction, allowing the leveling device to adjust the flatness of the refrigeration device in the left-to-right direction. Furthermore, because the operator can control the movement of the lifting component 22 of one adjustment component 2 by operating its lever 24, thereby adjusting the height between the lifting top cover 23 and the support base 21, the operator can adjust the flatness of the refrigeration device in both the front-to-back and left-to-right directions by operating each adjustment lever 24, thus improving the convenience of the leveling operation.

[0038] Reference Figure 2 , Figure 3 and Figure 6 In some embodiments, the operating end 241 of the operating lever 24 extends to the front side of the base body 1. The operating lever 24 of each adjustment component 2 extends to the front side of the base body 1, which means that the operator can control the height between the lifting top cover 23 and the support base 21 in each adjustment component 2 from the front side of the refrigeration equipment, thereby adjusting the flatness of the refrigeration equipment in the front-back direction and the left-right direction, which is convenient and quick for the operator to perform leveling operation.

[0039] In some specific embodiments, the two adjustment components 2 belonging to the same group of adjustment components 2 are not only spaced apart in the front-back direction, but the operating rods 24 of the two adjustment components 2 are also spaced apart in the left-right direction. This allows the operating ends 241 of the multiple adjustment components 2 in the leveling device to extend to the front side of the base body 1, making it convenient for the staff to adjust the height of the refrigeration equipment in the front-back and left-right directions from the front side of the refrigeration equipment, thereby meeting the flatness requirements of the refrigeration equipment in the front-back and left-right directions.

[0040] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, the lifting assembly 22 includes a first link 221 and a second link 222. The first end of the first link 221 is rotatably connected to the lifting top cover 23, and the first end of the second link 222 is rotatably connected to the support base 21. The second ends of the first link 221 and the second ends of the second link 222 are respectively pivotally connected to the first moving member 223. The operating lever 24 cooperates with the first moving member 223 to push the first moving member 223 to move.

[0041] Through the above technical solution, the operator can push the first moving component 223 to move using the operating lever 24. The movement of the first moving component 223 controls the lifting and lowering of the refrigeration equipment. When the first moving component 223 moves, the angle between the first connecting rod 221 and the second connecting rod 222 gradually increases, and the height between the lifting top cover 23 and the support base 21 gradually increases; conversely, when the first moving component 223 moves, the angle between the first connecting rod 221 and the second connecting rod 222 gradually decreases, and the height between the lifting top cover 23 and the support base 21 gradually decreases. The lifting component 22 in the above technical solution has a simple structure, reducing the production cost of the leveling device.

[0042] Reference Figure 2 , Figure 3 and Figure 5 In some specific embodiments, the first end of the first connecting rod 221 is rotatably connected to the lifting top cover 23 via the first pin 2211, and the first end of the second connecting rod 222 is rotatably connected to the support base 21 via the second pin 2221. Both the first pin 2211 and the second pin 2221 extend in the left-right direction, and the first pin 2211 is located directly above the second pin 2221. When the first moving member 223 moves toward a position closer to the space between the first pin 2211 and the second pin 2221, the first end of the first connecting rod 221 gradually moves away from the first end of the second connecting rod 222, meaning that the height between the lifting top cover 23 and the support base 21 gradually increases; when the first moving member 223 moves away from the space between the first pin 2211 and the second pin 2221, the first end of the first connecting rod 221 gradually moves closer to the first end of the second connecting rod 222, meaning that the height between the lifting top cover 23 and the support base 21 gradually decreases.

[0043] The operating lever 24 is threadedly engaged with the first movable component 223. This can be achieved by either fixing a nut to the first movable component 223 that is threadedly engaged with the operating lever 24, or by providing a threaded hole on the first movable component 223 that is threadedly engaged with the operating lever 24. Rotating the operating lever 24 moves the first movable component 223 along its axial direction; that is, rotating the operating lever 24 clockwise or counterclockwise moves the first movable component 223 forward or backward. By controlling the forward or backward movement of the first movable component 223, the position of the first movable component 223 relative to or away from the space between the first pin 2211 and the second pin 2221 is controlled, thereby controlling the raising or lowering of the lifting top cover 23.

[0044] The operating end 241 of the operating lever 24 can be a regular hexagonal prism. The operator can rotate the operating lever 24 by using an Allen wrench, socket, or electric gun socket to adjust the height of each lifting top cover 23, thereby adjusting the flatness of the refrigeration equipment. This is convenient and quick. In this application, the lifting top cover 23 is controlled by the threaded operating lever 24 and the first moving part 223, which improves the accuracy of the lifting top cover 23's rise and fall, and improves the accuracy of the refrigeration equipment's leveling.

[0045] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, the lifting assembly 22 further includes a third link 224 and a fourth link 225. The first end of the third link 224 is rotatably connected to the lifting top cover 23, and the first end of the fourth link 225 is rotatably connected to the support base 21. The second ends of the third link 224 and the second ends of the fourth link 225 are respectively pivotally connected to the second moving member 226. The operating lever 24 cooperates with the second moving member 226 to push the second moving member 226 to move.

[0046] The above technical solution enhances the stability of the lifting assembly 22 by cooperating with the third link 224 and the fourth link 225, improves the stability of the lifting assembly 22, and extends the service life of the leveling device.

[0047] Reference Figure 2 , Figure 3 and Figure 5In some specific embodiments, the first end of the third link 224 is rotatably connected to the lifting top cover 23 via the third pin 2241, and the first end of the fourth link 225 is rotatably connected to the support base 21 via the fourth pin 2251. Both the third pin 2241 and the fourth pin 2251 extend in the left-right direction, with the third pin 2241 located directly above the fourth pin 2251. When the second moving member 226 moves toward the position between the third pin 2241 and the fourth pin 2251, the height between the lifting top cover 23 and the support base 21 gradually increases; when the second moving member 226 moves away from the position between the third pin 2241 and the fourth pin 2251, the height between the lifting top cover 23 and the support base 21 gradually decreases. The second moving member 226 is threadedly connected to the operating lever 24. By rotating the operating lever 24 clockwise or counterclockwise, the second moving member 226 can be controlled to move forward or backward, thereby controlling the increase or decrease of the height between the lifting top cover 23 and the support base 21.

[0048] Reference Figure 2 , Figure 3 and Figure 5 In some further embodiments, the opening between the first link 221 and the second link 222 is opposite to the opening between the third link 224 and the fourth link 225. That is, when the first moving member 223 and the second moving member 226 approach each other, the height between the lifting top cover 23 and the support base 21 gradually increases, and when the first moving member 223 and the second moving member 226 move away from each other, the height between the lifting top cover 23 and the support base 21 gradually decreases.

[0049] Reference Figure 2 , Figure 3 and Figure 5 In some specific embodiments, the outer peripheral wall of the operating lever 24 is provided with a first external thread 242 and a second external thread 243 with opposite directions of rotation. The first moving part 223 is threadedly engaged with the first external thread 242, and the second moving part 226 is engaged with the second external thread 243. Through the above technical solution, when the operator rotates the operating lever 24, the first moving part 223 and the second moving part 226 move in opposite directions, and the first connecting rod 221, the second connecting rod 22, the third connecting rod 224 and the fourth connecting rod 225 move synchronously, which enhances the stability of the lifting assembly 22.

[0050] In one embodiment of this application, the third link 224 and the fourth link 225 are located in front of the first link 221 and the second link 222. When the operator rotates the operating lever 24 clockwise, the first moving member 223 moves forward and the second moving member 226 moves backward, bringing the first moving member 223 and the second moving member 226 closer together, and the height between the lifting top cover 23 and the support base 21 gradually increases; when the operator rotates the operating lever 24 counterclockwise, the first moving member 223 moves backward and the second moving member 226 moves forward, moving the first moving member 223 and the second moving member 226 further apart, and the height between the lifting top cover 23 and the support base 21 gradually decreases.

[0051] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, the first end of the first link 221 and the first end of the third link 224 are engaged. Through the above technical solution, the engagement of the first end of the first link 221 and the first end of the third link 224 allows the first link 221 and the third link 224 to support each other, improving the stability of the lifting assembly 22 and extending the service life of the leveling device.

[0052] In some specific embodiments, the first end of the first connecting rod 221 is provided with a plurality of teeth, which are arranged at intervals along the circumference of the first pin 2211; the first end of the third connecting rod 224 is also provided with a plurality of teeth, which are arranged at intervals along the circumference of the third pin 2241, and the teeth on the first connecting rod 221 mesh with the teeth on the third connecting rod 224.

[0053] In some embodiments, the first end of the second link 222 and the first end of the fourth link 225 are engaged.

[0054] Through the above technical solution, the first end of the second link 222 and the first end of the fourth link 225 mesh with each other, enabling the second link 222 and the fourth link 225 to support each other, thereby improving the stability of the lifting assembly 22 and extending the service life of the leveling device. Furthermore, the meshing of the first end of the first link 221 and the first end of the third link 224, and the meshing of the first end of the second link 222 and the first end of the fourth link 225, allows the lifting top cover 23 and the support base 21 to move stably in the vertical direction, further improving the stability of the lifting assembly 22 during lifting operations.

[0055] In some specific embodiments, the first end of the second connecting rod 222 is provided with a plurality of teeth, which are arranged at intervals along the circumference of the second pin 2221; the first end of the fourth connecting rod 225 is also provided with a plurality of teeth, which are arranged at intervals along the circumference of the fourth pin 2251, and the teeth on the second connecting rod 222 mesh with the teeth on the fourth connecting rod 225.

[0056] In some embodiments, the rotation angle range of the second link 222 and the fourth link 225 is 0-32°. When the first end of the second link 222 or the first end of the fourth link 225 contacts the ground or the bottom wall of the support base 21, it is the highest state of the lifting assembly 22, and the maximum adjustable height of the adjusting assembly 2 is 20mm. When the first link 221, the second link 222, the third link 224 and the fourth link 225 contact the operating lever 24, it is the lowest state of the lifting assembly 22.

[0057] Reference Figure 2 and Figure 4 In some embodiments, one of the base body 1 and the support 21 is provided with a first elongated hole, and the other of the base body 1 and the support 21 is provided with a mounting rod 25. The mounting rod 25 is movably engaged with the first elongated hole to install the adjusting component 2 onto the base body 1. When the lifting component 22 is moving, the mounting rod 25 can move within the first elongated hole, which provides clearance for the lifting and lowering of the mounting rod 25.

[0058] Through the above technical solution, not only can the adjustment component 2 be movably installed on the base body 1, but also the range of movement of the support base 21 relative to the base body 1 is limited by the cooperation of the first elongated hole and the mounting rod 25. The base body 1 will not rise or fall with the refrigeration equipment, and the base body 1 can always be supported on the ground, which enhances the stability of the leveling device.

[0059] Reference Figure 4 , Figure 6 and Figure 7In some specific embodiments, at least two mounting rods 25 are constructed, and the two mounting rods 25 are coaxially fixed to the second pin 2221 and the fourth pin 2251, respectively, and the first elongated hole extends in the vertical direction. The front side of the base body 1 is provided with a second elongated hole 101 to avoid the operating rod 24. When the lifting assembly 22 is in the retracted state, that is, when the lifting top cover 23 is close to the support seat 21, the adjusting assembly 2 is hung on the base body 1, and the support seat 21 is spaced apart from the ground. The adjusting assembly 2 can be hung on the base body 1 via the operating rod 24, or it can be hung on the base body 1 via the lifting top cover 23. In this case, the operating rod 24 is located at the lower end of the second elongated hole 101, and the mounting rod 25 is located at the upper end of the first elongated hole. As the lifting assembly 22 begins to extend, the height between the lifting top cover 23 and the support base 21 gradually increases. The support base 21 moves closer to the ground, and the mounting rod 25 moves downward within the first elongated hole, which provides space for the movement of the mounting rod 25. After the support base 21 is supported on the ground, the mounting rod 25 is located at the lower end of the first elongated hole. The lifting assembly 22 continues to extend, and the height between the lifting top cover 23 and the support base 21 continues to increase. Because the support base 21 is supported on the ground, the lifting top cover 23 begins to move upward, driving the refrigeration equipment upward. At this time, the operating rod 24 moves upward within the second elongated hole 101, which provides space for the upward movement of the operating rod 24.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the base body 1 includes two parallel extending mounting seats 11 and a connector, each mounting seat 11 is equipped with at least one set of adjustment components 2, and the left and right ends of the connector are respectively connected to the two mounting seats 11.

[0061] With the above technical solution, the base body 1 includes two parallel extending mounting seats 11. The two mounting seats 11 are spaced apart in the left and right directions. The space at the bottom of the refrigeration equipment other than the space occupied by the mounting seats 11 can be used as the heat dissipation space of the refrigeration equipment, thereby improving the heat dissipation efficiency of the refrigeration equipment.

[0062] In some embodiments, the connector is a skirting board grille 12, which is disposed on the front side of the two mounting seats 11, and the left and right ends of the skirting board grille 12 are respectively connected to the two mounting seats 11. The skirting board grille 12 can be installed on the mounting seats 11 by screws. In the above technical solution, the skirting board grille 12 enhances the refined appearance of the refrigeration equipment.

[0063] Reference Figure 2 , Figure 7 and Figure 8In some embodiments, the leveling device further includes a roller assembly 3, which is mounted on the base body 1. By providing the roller assembly 3 on the leveling device, the ease of moving the refrigeration equipment is improved. In some specific embodiments, each mounting base 11 is equipped with at least two roller assemblies 3, which are spaced apart in the front-to-back direction. When the lifting assembly 22 is in the retracted state, the leveling device is supported on the ground by the roller assemblies 3.

[0064] In some embodiments, the roller assembly 3 includes a roller seat 31, which is mounted on the bottom side of the mounting base 11. The roller seat 31 has a higher structural strength than the mounting base 11. A roller 32 is rotatably mounted on the bottom side of the roller seat 31 via a pin. Because the roller 32 needs to be supported on the ground, it experiences significant pressure. The high structural strength of the roller seat 31 alleviates the localized stress between the roller 32 and the mounting base 11, reducing the possibility of deformation of the mounting base 11 and improving the stability of the leveling device.

[0065] In one embodiment of this application, the mounting base 11 is constructed of high-strength PA+glass fiber material, and the roller base 31 is constructed of galvanized sheet.

[0066] A refrigerator set according to an embodiment of this application includes a refrigerator and a leveling device. The leveling device is a type of leveling device proposed in this application and is installed at the bottom of the refrigerator. Because the refrigerator set proposed in this application includes the leveling device proposed in this application, it also has the advantages of being able to adjust the flatness of the refrigerator in the front-to-back direction and the flatness in the left-to-right direction, as well as the convenience of adjusting the front-to-back and left-to-right height of the refrigerator from the front side.

[0067] Reference Figure 6 , Figure 7 and Figure 9 In some embodiments, the leveling device is detachably installed at the bottom of the refrigerator. When transporting the refrigerator, the leveling device can be removed from the bottom, reducing the refrigerator's height and facilitating its storage and transport. The detachable installation at the bottom also facilitates the maintenance and replacement of the leveling device.

[0068] Specifically, the base body 1 includes: two parallel mounting seats 11, each mounting seat 11 extending in the front-back direction, each mounting seat 11 having two roller assemblies 3 mounted on it, the two roller assemblies 3 being spaced apart in the front-back direction, and each mounting seat 11 having two adjustment components 2 mounted on it, the two adjustment components 2 being spaced apart in the front-back direction.

[0069] Each mounting base 11 has a positioning step 111 on its top for positioning in the left-right direction of the refrigerator bottom, and a positioning sidewall on the bottom of the refrigerator that mates with the positioning step 111. Each mounting base 11 also has a plug 112 on its top, and a corresponding insertion hole for the plug 112 is provided on the bottom wall of the refrigerator. In other embodiments, the plug 112 may be located on the bottom wall of the refrigerator, and the corresponding insertion hole for the plug 112 may be provided on the top of the mounting base 11.

[0070] When installing the leveling device, first tilt the refrigerator to the left, then place one mounting base 11 at the bottom of the refrigerator and move the mounting base 11 left and right until the positioning step 111 contacts the positioning side wall, thus completing the left-right positioning of the mounting base 11. Then move the mounting base 11 back and forth until the plug 112 is inserted into the socket, thus completing the installation of the mounting base 11. Next, tilt the refrigerator to the right to install the other mounting base 11, thereby completing the installation of the leveling device.

[0071] Some refrigerators are built-in cabinet refrigerators, which need to be installed inside cabinets. In order to achieve automatic centering of the refrigerator when it enters the cabinet, in some embodiments, the left side wall of the mounting base 11 on the left is a first guide wall, and the right side wall of the mounting base 11 on the right is a second guide wall. The first guide wall and the second guide wall protrude from the left side wall and the right side wall of the refrigerator, respectively, and the distance between the first guide wall and the second guide wall gradually increases in the direction from back to front. The first guide wall and the second guide wall are symmetrically arranged on the left and right sides of the refrigerator.

[0072] When installing a built-in refrigerator, first install the two mounting brackets 11 onto the bottom of the refrigerator. Then, move the refrigerator into the cabinet using the roller assembly 3. During the movement, the refrigerator automatically centers itself within the cabinet with the help of the first and second guide walls. After the refrigerator enters the cabinet, the operator uses an Allen wrench, socket, or electric arc gun to rotate the operating lever 24 to level the refrigerator. After leveling the refrigerator, install the baseboard grille 12 onto the two mounting brackets 11.
