In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0045] It should be noted that the adjustment mechanism of the present invention can be used for household appliances placed in corners or built-in household appliances. The use of a refrigerator as an example is not a limitation of the present invention. The adjustment mechanism of the present invention can be used in other household appliances that need to be adjusted.

[0046] According to the adjustment mechanism of the embodiment of the present invention, please refer to Figure 1 and Figure 2 The adjustment mechanism includes a first mounting seat 100, a second mounting seat 200, a connecting rod assembly 300, a threaded rod 400, a connecting member 500 and a supporting foot 600. The first mounting seat 100 is provided with a threaded hole 101; the second mounting seat 200 is spaced apart from the first mounting seat 100; the threaded rod 400 is passed 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 includes 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 rotationally connected through a first pin shaft 340, and the second connecting rod 320 and the third connecting rod 330 are rotationally connected through a second pin shaft 350; the connecting member 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 a linear motion 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 foot 600 is connected to the rotation connection between the second connecting rod 320 and the third connecting rod 330.

[0047] According to the adjustment mechanism of the embodiment of the present invention, through the connecting rod assembly 300 and the connecting member 500, the connecting member 500 can convert the movement of the threaded rod 400 into the linear motion of the first connecting rod 310, and 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 rotation connection between the second connecting rod 320 and the third connecting rod 330 and the second mounting base 200, so that the distance between the supporting foot 600 and the horizontal plane where the second mounting base 200 is located is adjustable to meet the needs of different users.

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

[0049] The support foot 600 may also be a part of the second connecting rod 320, the third connecting rod 330 or the second axle pin 350. In other words, the support foot 600 may be integrally formed with the second connecting rod 320 or the third connecting rod 330. The support foot may also be integrally formed with the second axle pin 350. The present invention does not limit the specific connection or formation position of the support foot 600, as long as the support foot can support the installation object of the adjustment mechanism.

[0050] It is understandable that the spiral structure of the threaded rod 400 can convert the rotational force into linear motion, thereby achieving height adjustment. Compared with directly pushing and pulling the adjustment mechanism, adjusting by rotating the threaded rod 400 can provide a more stable support force for the connecting rod assembly and has better reliability. In addition, the threaded rod 400 can be used in conjunction with other mechanisms or devices. For example, the threaded rod 400 can be connected to a hexagonal screw, thereby extending the user's operating range of the adjustment mechanism and facilitating the user's adjustment.

[0051] It can be understood that the overall structure of the adjustment mechanism is simple, and the user only needs to install the first mounting seat 100 and the second mounting seat 200 of the adjustment mechanism to the desired position to level the household appliance. The adjustment mechanism is simple to use and easy to install.

[0052] The motion process of the adjusting mechanism of the present invention is described below with a specific embodiment:

[0053] The adjustment mechanism is installed at the bottom of the refrigerator body 800, please refer to Figure 3The first mounting seat 100 and the second mounting seat 200 are arranged at a distance from each other at the bottom of the refrigerator, and the support leg 600, the first mounting seat 100 and the second mounting seat 200 form a stable structure. The user rotates the threaded rod 400 in the forward direction, and the threaded rod 400 can move toward the second mounting seat 200 along the axial direction of the threaded hole 101. The threaded rod 400 moves, driving the connecting member 500 and the first connecting rod 310 to make a linear motion 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 accordingly, and the angle between the second connecting rod 320 and the third connecting rod 330 becomes smaller, driving the support leg 600 away from the refrigerator body 800. The user rotates the threaded rod 400 in the opposite direction, and the threaded rod 400 moves along the axial direction of the threaded hole 101 away from the second mounting seat 200, and drives the connecting piece 500 and the first connecting rod 310 to make linear motion 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 make corresponding rotations, and the angle between the second connecting rod 320 and the third connecting rod 330 becomes larger, driving the supporting foot 600 close to the refrigerator body 800.

[0054] According to an embodiment of the present invention, please refer to Figure 1 and Figure 2 The adjustment mechanism further includes a support assembly 700, which is adapted to provide support for at least one of the first pin 340 and the first connecting rod 310. It is understandable that the support assembly 700 provides support for sharing the force of the threaded rod 400, enhancing the bearing capacity of the threaded rod 400, and is conducive to improving the stability and reliability of the threaded rod 400.

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

[0056] According to an embodiment of the present invention, please refer to Figure 1 and Figure 4 The support assembly 700 includes a third mounting seat 710 and a damping rod 720 . The third mounting seat 710 is arranged between the second mounting seat 200 and the first mounting seat 100 . The first end of the damping rod 720 is hinged to the third mounting seat 710 , and the second end of the damping rod 720 is hinged to the first pin shaft 340 .

[0057] It is understandable 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. With the movement of the connecting rod assembly 300, the damping rod 720 can adjust the position and angle of the damping rod 720 to adapt to the change of the connecting rod assembly 300. When the adjustment mechanism is installed at the bottom of the household appliance, the support foot 600 bears the weight of the household appliance and reacts the support force to the second connecting rod 320 and the third connecting rod 330. The force of the second connecting rod 320 will be transmitted to the first connecting rod 310 through the first pin shaft 340. By hingedly connecting the damping rod 720 to the first pin shaft 340, the support assembly 700 can well share the force of the threaded rod 400, so that the overall stability of the adjustment 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 connector, the rod body is a straight rod with a certain length, the connector is a cylinder with a certain depth, the straight rod is inserted into the cylinder, a damping element is arranged inside the cylinder or an oil damping agent is filled therein, the damping agent can be a liquid, a gas or a semi-solid material, and the damping element can be a spring or an elastic structure.

[0059] In one embodiment, a mounting groove (not shown) is provided at the bottom of the refrigerator, the third mounting seat 710 is provided in the mounting groove, and the damping rod 720 is at least partially located in the mounting groove. It is understandable that by providing the mounting groove, the distance between the first pin shaft 340 and the third mounting seat 710 is larger, and a damping rod 720 with a standard length and better damping effect on the market can be used, without the need to manufacture the damping rod 720 separately, thereby reducing the manufacturing difficulty of the adjustment mechanism.

[0060] In one embodiment, the support assembly 700 provides support force for the second pin shaft 350 to share the force of the first pin shaft 340 , the first connecting rod 310 , and the threaded rod 400 , which is beneficial to improving the stability and reliability of the connecting rod assembly 300 .

[0061] According to an embodiment of the present invention, please refer to Figure 5 The support 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 slide rail 731. The first end of the connecting rod 740 is provided with a slider 741. The slider 741 is slidably connected to the slide rail 731. The second end of the connecting rod 740 is connected to the first connecting rod 310 or the first pin shaft 340.

[0062] It is understandable that the connecting rod 740 and the slider 741 can be fixedly connected or integrally formed. The slider 741 is slidably connected to the slide rail 731, and is suitable for being slidably connected to the slide rail 731 along the track of the slide rail 731, and the track extension direction of the slide rail 731 is parallel to the axial direction of the threaded hole 101 of the first mounting seat 100. By setting the fourth mounting seat 730 and the connecting rod 740, the support assembly 700 can well share the force of the threaded rod 400, so that the overall stability of the adjustment 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 when the slider 741 slides on the slide rail 731, the damper provides resistance to the slider 741, thereby increasing the force sharing effect of the support assembly 700 on the threaded rod 400. The damper can be a gas damper, a liquid damper, a spring damper or a friction damper.

[0064] In one embodiment, the supporting component includes a third mounting seat 710 and a damping rod 720, and a fourth mounting seat 730 and a connecting rod 740. The first end of the damping rod 720 is hinged to the third mounting seat 710, the second end of the damping rod 720 is connected to the first pin 340, the first end of the connecting rod 740 is provided with a slider 741, the slider 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 340 and connecting the connecting rod 740 to the first connecting rod 310, the force of the threaded rod 400 can be effectively shared, providing a more stable supporting force, and the overall stability of the adjustment mechanism is stronger.

[0065] According to an embodiment of the present invention, please refer to Figure 2 The connecting member 500 includes a first shell 510 and a second shell 520 that are interlocked with 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 can be rotatably connected to the connecting hole 530, and at least one of the first shell 510 and the second shell 520 is fixed to the first connecting rod 310.

[0066] It is understandable that the first shell 510 and the second shell 520 that can be interlocked are convenient for users to disassemble and assemble. A connecting hole 530 is formed between the first shell 510 and the second shell 520 to facilitate 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 causing the connecting member 500 to rotate as a whole. In other words, by providing 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 is fixed to the first connecting rod 310 to achieve a reliable connection between the connecting member 500 and the first connecting rod 310.

[0067] In one embodiment, please refer to Figure 2 The first housing 510 and the second housing 520 are connected together by four screws to ensure that the first housing 510 and the second housing 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 a snap, one of the first shell 510 and the second shell 520 is provided with a snap protrusion, and the other is provided with a snap groove. The present invention does not impose specific restrictions on this.

[0069] According to an embodiment of the present invention, 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 a dovetail protrusion 311 matching the dovetail groove 540 is formed at the end of the first connecting rod 310. 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 secure. The matching of the dovetail protrusion 311 and the dovetail groove 540 creates a locking structure to prevent the connector 500 from loosening or falling off under the action of stress and vibration. In addition, the shape of the dovetail groove 540 can also enhance the anti-torsion ability of the connector 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 rotational freedom of the dovetail groove 540. The dovetail structure of the dovetail groove 540 can achieve uniform force, reduce the risk of local stress concentration, and improve the load resistance of the connector 500.

[0070] Of course, a groove of other shapes may be formed between the first shell 510 and the second shell 520 , and a protrusion matching the groove may be formed at the end of the first connecting rod 310 , and the present invention does not impose any specific limitation on this.

[0071] According to an embodiment of the present invention, please refer to Figure 2 and Figure 3 , the end of the connecting hole 530 facing the first connecting rod 310 is provided with a reaming section 531, and the end of the threaded rod 400 is provided with a limiting platform 410, and the limiting platform 410 is installed on the reaming section 531. It can be understood that the limiting platform 410 is used to cooperate with the reaming section 531. When the threaded rod 400 rotates in the opposite direction, the limiting platform 410 and the connecting hole 530 are limited, so that the movement of the threaded rod 400 can drive the connecting member 500 to move. The reaming section 531 can be a trumpet hole or a stepped hole, as long as it can form a limit for the limiting platform 410.

[0072] According to an embodiment of the present invention, please refer to Figure 1The first end of the first connecting rod 310 has two first lugs 312 arranged opposite to each other, and the first end of the second connecting rod 320 has a second lug 321, and the second lug 321 is inserted between the two first lugs 312, forming a structure connecting the first connecting rod 310 and the second connecting rod 320. Such an installation method can ensure that the connection between the first connecting rod 310 and the second connecting rod 320 is firm, increase the stability of the structure, and reduce the possibility of loosening or falling off. The second end of the second connecting rod 320 has two third lugs 322 arranged opposite to each other, and the first end of the third connecting rod 330 has a fourth lug 331, and the fourth lug 331 is inserted between the two third lugs 322, forming a structure connecting the second connecting rod 320 and the third connecting rod 330. Such an installation method can ensure that the connection between the second connecting rod 320 and the third connecting rod 330 is firm.

[0073] It can be understood that by plugging the first lug 312 and the second lug 321, and the third lug 322 and the fourth lug 331, the connection stability of the connecting rod assembly can be effectively ensured, and the connecting rods provided with lugs (including the first connecting rod 310, the second connecting rod 320 and the third connecting rod 330) are easy to assemble and convenient for users to use.

[0074] According to an embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 , the second pin 350 is inserted through the through hole 360 ​​on the third lug 322 and the through hole 360 ​​on the fourth lug 331, and the number of the supporting legs 600 is an even number, and they are symmetrically installed at both ends of the second pin 350. By inserting the second pin 350 through the through holes 360 on the third lug 322 and the fourth lug 331, the position of the second pin 350 can be relatively fixed, thereby increasing the stability of the entire structure. Since the number of the supporting legs 600 is an even number and they are symmetrically installed at both ends of the second pin 350, the load-bearing force can be balanced, thereby improving the load-bearing capacity of the entire structure.

[0075] According to the refrigerator of the second embodiment of the present invention, please refer to Figure 3 and Figure 5 , including a refrigerator body 800 and the above-mentioned adjustment mechanism. The second mounting seat 200 is connected to the bottom rear end of the refrigerator body 800.

[0076] It is understandable that the operator adjusts the bottom of the refrigerator to a level by twisting the threaded rod 400. There is no need to remove the entire refrigerator, which is very convenient to use.
