[0045] It should be noted that the adjusting mechanism of the present application can be used for household appliances placed in the corner of the wall, or embedded household appliances. The present application takes a refrigerator as an example, which is not a limitation of the present application. The adjusting mechanism of the present application can be used in other household appliances that need to be adjusted.

[0046] According to the adjusting mechanism of the embodiment of the present application, please refer to Figure 1 and Figure 2 The adjusting mechanism comprises a first mounting seat 100, a second mounting seat 200, a connecting rod assembly 300, a threaded rod 400, a connecting piece 500 and a supporting leg 600. The first mounting seat 100 is provided with a threaded hole 101; the second mounting seat 200 is arranged at intervals with the first mounting seat 100; the threaded rod 400 is arranged through the threaded hole 101, and the threaded rod 400 is suitable for axial movement along the threaded hole 101; the connecting rod assembly 300 is connected between the threaded rod 400 and the second mounting seat 200, and the connecting rod assembly 300 comprises a first connecting rod 310, a second connecting rod 320 and a third connecting rod 330. The first connecting rod 310 and the second connecting rod 320 are rotatably connected through a first pin shaft 340, and the second connecting rod 320 and the third connecting rod 330 are rotatably connected through a second pin shaft 350; the connecting piece 500 connects the threaded rod 400 and the first connecting rod 310, and is suitable for converting the movement of the threaded rod 400 into the linear movement of the first connecting rod 310, so as to drive the second connecting rod 320 to rotate and drive the third connecting rod 330 to rotate around the second mounting seat 200; the supporting leg 600 is connected to the rotating connection between the second connecting rod 320 and the third connecting rod 330.

[0047] According to the adjusting mechanism of the embodiment of the present application, the connecting piece 500 can convert the movement of the threaded rod 400 into the linear movement of the first connecting rod 310 through the connecting rod assembly 300 and the connecting piece 500, the movement of the first connecting rod 310 can drive the second connecting rod 320 and the third connecting rod 330 to rotate, thereby changing the distance between the rotating connection of the second connecting rod 320 and the third connecting rod 330 and the second mounting base 200, so that the distance between the support leg 600 and the horizontal plane where the second mounting base 200 is located can be adjusted, which can meet the needs of different users.

[0048] It can be understood that the support leg 600 is used to support the entire adjusting mechanism. The support leg 600 can be a separate component installed at the rotating connection of the second connecting rod 320 and the third connecting rod 330. The connection of the support leg 600 to the rotating connection of the second connecting rod 320 and the third connecting rod 330 can be understood as the connection of the support leg 600 to one of the second connecting rod 320, the third connecting rod 330 or the second pin shaft 350. In other words, the support leg 600 can be connected to the second pin shaft 350, or to the second connecting rod 320 or the third connecting rod 330, for example, the support leg 600 can be connected to the edge of one end of the second connecting rod 320.

[0049] The support leg 600 can also be a part of the second connecting rod 320, the third connecting rod 330 or the second pin shaft 350. In other words, the support leg 600 can be integrally formed with the second connecting rod 320 or the third connecting rod 330, or integrally formed with the second pin shaft 350. The present application does not limit the specific connection or formation position of the support leg 600, as long as the support leg can support the mounting object of the adjusting mechanism.

[0050] It can be understood that the screw structure of the threaded rod 400 can convert the rotating force into linear movement, thereby achieving the adjustment of the height. Compared with directly pushing and pulling the adjusting mechanism, the adjustment through the rotation of the threaded rod 400 can provide more stable support force for the connecting rod assembly, and has better reliability. Moreover, the threaded rod 400 can be used in cooperation with other mechanisms or devices, for example, the threaded rod 400 can be connected to a hexagonal screw rod, thereby extending the operation range of the user for the adjusting mechanism, and facilitating the user to adjust.

[0051] It can be understood that the adjusting mechanism has a simple overall structure, and the user only needs to install the first mounting base 100 and the second mounting base 200 of the adjusting mechanism to the desired position to realize the leveling of the household appliance. The adjusting mechanism is simple to use and convenient to install.

[0052] The movement process of the adjusting mechanism of the present application will be described below with a specific embodiment:

[0053] The adjusting mechanism is installed at the bottom of the refrigerator body 800. Please refer to Figure 3The first mounting base 100 and the second mounting base 200 are arranged at the bottom of the refrigerator, and the supporting leg 600, the first mounting base 100 and the second mounting base 200 form a stable structure. When the user rotates the threaded rod 400 in a forward direction, the threaded rod 400 can move along the axial direction of the threaded hole 101 towards the second mounting base 200, the movement of the threaded rod 400 drives the connecting piece 500 and the first connecting rod 310 to move linearly along the axial direction of the threaded hole 101, the movement of the first connecting rod 310 drives the second connecting rod 320 and the third connecting rod 330 to rotate correspondingly, the included angle between the second connecting rod 320 and the third connecting rod 330 becomes smaller, and the supporting leg 600 is driven to move away from the refrigerator body 800. When the user rotates the threaded rod 400 in a reverse direction, the threaded rod 400 moves along the axial direction of the threaded hole 101 away from the second mounting base 200, and drives the connecting piece 500 and the first connecting rod 310 to move linearly along the axial direction of the threaded hole 101, the first connecting rod 310 drives the second connecting rod 320 and the third connecting rod 330 to rotate correspondingly, the included angle between the second connecting rod 320 and the third connecting rod 330 becomes larger, and the supporting leg 600 is driven to move close to the refrigerator body 800.

[0054] According to one embodiment of the present application, please refer to Figure 1 and Figure 2 The adjusting mechanism further comprises a supporting assembly 700, which is adapted to provide a supporting force for at least one of the first pin shaft 340 and the first connecting rod 310. It can be understood that the supporting assembly 700 provides a supporting force for sharing the stress of the threaded rod 400, enhances the load capacity of the threaded rod 400, and is beneficial to improve the stability and reliability of the threaded rod 400.

[0055] It should be noted that the supporting assembly 700 can be arranged at one of the first pin shaft 340 and the first connecting rod 310, or at multiple places of the first pin shaft 340 and the first connecting rod 310. By arranging the supporting assembly 700 at multiple places, the stability of the adjusting mechanism can be increased, and arranging the supporting assembly 700 at multiple key positions can disperse stress and help reduce the risk of fatigue and damage of the threaded rod 400, thereby prolonging the service life of the adjusting mechanism.

[0056] According to one embodiment of the present application, please refer to Figure 1 and Figure 4 The supporting assembly 700 comprises a third mounting base 710 and a damping rod 720, the third mounting base 710 is arranged between the second mounting base 200 and the first mounting base 100, the first end of the damping rod 720 is hinged to the third mounting base 710, and the second end of the damping rod 720 is hinged to the first pin shaft 340.

[0057] It can be understood that the damping rod 720 provides support for the movement of the second pin shaft 350. The first end of the damping rod 720 is hinged to the third mounting seat 710, and as the linkage assembly 300 moves, the damping rod 720 can adjust the position and angle of the damping rod 720 to adapt to the change of the linkage assembly 300. When the adjusting mechanism is installed at the bottom of the household appliance, the supporting leg 600 bears the weight of the household appliance and reacts the supporting force to the second linkage 320 and the third linkage 330, and the force of the second linkage 320 will be transmitted to the first linkage 310 through the first pin shaft 340. By hinging the damping rod 720 at the first pin shaft 340, the supporting assembly 700 can well share the stress of the threaded rod 400, so that the overall stability of the adjusting mechanism is stronger, and the service life of the threaded rod 400 is guaranteed.

[0058] In one embodiment, the damping rod 720 includes a rod body and a connecting body, the rod body is a straight rod with a certain length, and the connecting body is a cylinder with a certain depth, the straight rod is arranged in the cylinder, and a damping member or a filling oil damping agent is arranged in the cylinder. The damping agent can be a liquid, a gas or a semi-solid material, and the damping member can be a spring or an elastic structure.

[0059] In one embodiment, the bottom of the refrigerator is provided with a mounting groove (not labeled in the figure), and the third mounting seat 710 is arranged in the mounting groove, and the damping rod 720 is at least partially located in the mounting groove. It can be understood that by arranging the mounting groove, the distance between the first pin shaft 340 and the third mounting seat 710 is larger, the damping rod 720 with a standard length on the market and better damping effect can be used, and the damping rod 720 does not need to be additionally and independently manufactured, thereby reducing the manufacturing difficulty of the adjusting mechanism.

[0060] In one embodiment, the supporting assembly 700 provides support force for the second pin shaft 350, so as to share the stress of the first pin shaft 340, the first linkage 310 and the threaded rod 400, thereby facilitating to improve the stability and reliability of the linkage assembly 300.

[0061] According to one embodiment of the present application, please refer to Figure 5 , the supporting assembly 700 includes a fourth mounting seat 730 and a connecting rod 740, the fourth mounting seat 730 is arranged between the second mounting seat 200 and the first mounting seat 100, the fourth mounting seat 730 is provided with a sliding rail 731, the first end of the connecting rod 740 is provided with a sliding block 741, the sliding block 741 is slidingly connected to the sliding rail 731, and the second end of the connecting rod 740 is connected to the first linkage 310 or the first pin shaft 340.

[0062] It can be understood that the connecting rod 740 and the sliding block 741 can be fixedly connected or integrally formed. The sliding block 741 is slidably connected to the slide rail 731 and is adapted to slide along the track of the slide rail 731, and the extending direction of the track of the slide rail 731 is parallel to the axial direction of the threaded hole 101 of the first mounting seat 100. By arranging the fourth mounting seat 730 and the connecting rod 740, the support assembly 700 can well share the stress of the threaded rod 400, so that the overall stability of the adjusting mechanism is stronger, and the service life of the threaded rod 400 is guaranteed.

[0063] In one embodiment, the slide rail 731 is provided with a damper (not shown in the figure), and the damper provides resistance to the sliding block 741 when the sliding block 741 slides on the slide rail 731, thereby increasing the sharing of the stress of the threaded rod 400 by the support assembly 700. The damper can be a gas damper, a liquid damper, a spring damper, or a friction damper.

[0064] In one embodiment, the support component simultaneously includes the third mounting seat 710 and the damping rod 720, and the fourth mounting seat 730 and the connecting rod 740. The first end of the damping rod 720 is hingedly connected to the third mounting seat 710, the second end of the damping rod 720 is connected to the first pin shaft 340, the first end of the connecting rod 740 is provided with the sliding block 741, the sliding block 741 is slidably connected to the slide rail 731, and the second end of the connecting rod 740 is connected to the first connecting rod 310. It can be understood that, by hingedly connecting the damping rod 720 to the first pin shaft 340 and connecting the connecting rod 740 to the first connecting rod 310, the stress of the threaded rod 400 can be effectively shared, a more stable support force is provided, and the overall stability of the adjusting mechanism is stronger.

[0065] According to one embodiment of the present application, please refer to Figure 2 The connecting piece 500 includes a first shell 510 and a second shell 520 that are buckled to each other, a connecting hole 530 is formed between the first shell 510 and the second shell 520, one end of the threaded rod 400 is rotatably connected to the connecting hole 530, and at least one of the first shell 510 and the second shell 520 is fixed with the first connecting rod 310.

[0066] It can be understood that the first shell 510 and the second shell 520 that can be buckled to each other facilitate user disassembly, the connecting hole 530 formed between the first shell 510 and the second shell 520 facilitates the threaded rod 400 to be rotatably connected to the connecting hole 530, the threaded rod 400 can rotate in the connecting hole 530 without rotating the entire connecting piece 500, in other words, by arranging the connecting hole 530, the rotation and linear motion of the threaded rod 400 are converted into linear motion. At least one of the first shell 510 and the second shell 520 being fixed with the first connecting rod 310 can realize reliable connection between the connecting piece 500 and the first connecting rod 310.

[0067] In one embodiment, please refer to Figure 2 , the first shell 510 and the second shell 520 are connected together by four screws. It is ensured that the first shell 510 and the second shell 520 will not fall off during the movement of the threaded rod 400.

[0068] Of course, the first shell 510 and the second shell 520 can also be connected together in other ways, for example, they can be detachably connected in the form of buckles, one of the first shell 510 and the second shell 520 is provided with a buckle protrusion, and the other is provided with a buckle groove, and the present application does not make specific limitations here.

[0069] According to one embodiment of the present application, please refer to Figure 2 and Figure 3 , a dovetail groove 540 is formed between the first shell 510 and the second shell 520, and the end of the first connecting rod 310 is formed with a dovetail protrusion 311 matched with the dovetail groove 540. It can be understood that the design of the dovetail groove 540 makes the connection between the first shell 510 and the second shell 520 more firm. The matching of the dovetail protrusion 311 and the dovetail groove 540 creates a locking structure to prevent the connecting piece 500 from loosening or falling off under the action of stress and vibration. Moreover, the shape of the dovetail groove 540 can also enhance the torsional resistance of the connecting piece 500. After the first shell 510 and the second shell 520 are buckled, the dovetail protrusion 311 can be embedded in the dovetail groove 540, and the dovetail protrusion 311 limits the rotation freedom of the dovetail groove 540. The dovetail structure of the dovetail groove 540 can realize uniform stress and reduce the risk of local stress concentration, thereby improving the load resistance of the connecting piece 500.

[0070] Of course, other shaped grooves can also be formed between the first shell 510 and the second shell 520, and the end of the first connecting rod 310 is formed with a protrusion matched with the groove, and the present application does not make specific limitations here.

[0071] According to one embodiment of the present application, please refer to Figure 2 and Figure 3 , the connecting hole 530 is provided with an enlarged hole section 531 at one end facing the first connecting rod 310, and the end of the threaded rod 400 is provided with a limiting table 410, and the limiting table 410 is installed in the enlarged hole section 531. It can be understood that the limiting table 410 is used to cooperate with the enlarged hole section 531, and when the threaded rod 400 is reversely rotated, the limiting table 410 and the connecting hole 530 are limited, so that the movement of the threaded rod 400 can drive the connecting piece 500 to move. The enlarged hole section 531 can be a trumpet hole or a stepped hole, as long as it can limit the limiting table 410.

[0072] According to one embodiment of the present application, please refer to Figure 1The first end of the first connecting rod 310 is provided with two first lugs 312 arranged oppositely, the first end of the second connecting rod 320 is provided with a second lug 321, and the second lug 321 is inserted between the two first lugs 312 to form a structure connecting the first connecting rod 310 and the second connecting rod 320. Such an installation mode can ensure the firm connection between the first connecting rod 310 and the second connecting rod 320, increase the stability of the structure, and reduce the possibility of loosening or falling off. The second end of the second connecting rod 320 is provided with two third lugs 322 arranged oppositely, the first end of the third connecting rod 330 is provided with a fourth lug 331, and the fourth lug 331 is inserted between the two third lugs 322 to form a structure connecting the second connecting rod 320 and the third connecting rod 330. Such an installation mode can ensure the firm connection between the second connecting rod 320 and the third connecting rod 330.

[0073] It can be understood that the insertion between the first lug 312 and the second lug 321 and the insertion between the third lug 322 and the fourth lug 331 can effectively ensure the connection stability of the connecting rod assembly, and the connecting rod provided with the lug (including the first connecting rod 310, the second connecting rod 320, and the third connecting rod 330) is simple to assemble and convenient for users to use.

[0074] According to one embodiment of the present application, please refer to Figure 1 , Figure 3 and Figure 4 , the second pin shaft 350 is inserted into the insertion hole 360 on the third lug 322 and the insertion hole 360 on the fourth lug 331, the number of support feet 600 is even, and the support feet 600 are symmetrically installed at both ends of the second pin shaft 350. By inserting the second pin shaft 350 into the insertion hole 360 on the third lug 322 and the insertion hole 360 on the fourth lug 331, the position of the second pin shaft 350 can be relatively fixed, thereby increasing the stability of the entire structure. Since the number of support feet 600 is even and the support feet 600 are symmetrically installed at both ends of the second pin shaft 350, the bearing force can be balanced, thereby improving the bearing capacity of the entire structure.

[0075] According to the refrigerator of the second embodiment of the present application, please refer to Figure 3 and Figure 5 , the refrigerator body 800 and the adjusting mechanism described above are included.
