[0030] This embodiment provides a mobile bracket, which is used to lift household appliances, and users can move the household appliances by dragging such a mobile bracket.

[0031] The mobile bracket includes an outer groove plate 100, an inner groove plate, a rotating handle and rollers. As Figures 1 to 3 shown, in this embodiment, a connection port 110 is respectively provided at both ends of the outer groove plate 100. The connection port 110 is configured as a slot or a through hole and can be fixed to the feet of the household appliance. The inner groove plate is movably connected to the outer groove plate 100, and the inner groove plate can slide along the length direction of the outer groove plate 100. The rotating handle is hinged to the outer groove plate, and rollers are provided on the inner groove plate or the outer groove plate. When the rotating handle is rotated, the inner groove plate slides, so that the rollers extend out or retract into the inner groove plate. When the rollers extend out of the inner groove plate, the mobile bracket can lift the household appliance, and the household appliance can slide on the ground through the rollers. It should be emphasized that when the rollers retract into the inner groove plate, it can be interpreted as completely retracting or incompletely retracting into the inner groove plate. In this state, the feet of the household appliance are in contact with the ground, thereby undertaking the main load-bearing work.

[0032] The specific principle is prior art and can be referred to Patent Document 2022217823631, Patent Document 2024204922394, etc., and the applicant will not elaborate here.

[0033] As Figure 1 、 2 shown in the figure, the outer groove plate 100 includes a top 120 and a bottom 130. The bottom 130 is used to cooperate with the inner groove plate and the roller, and the top 120 faces away from the bottom 130 and is used to fit against the household appliance. Among them, the top 120 of the outer groove plate 100 is generally a planar structure, and a rib plate 140 protruding upward is formed on this plane. The connection port 110 is located within the top region of the rib plate 140, and the rib plate 140 plays a supporting role.

[0034] In this way, when the outer groove plate 100 is fixedly connected to the feet at the bottom of the household appliance, the rib plate 140 can effectively make up for the height difference caused by the reinforcing ribs at the bottom of the household appliance, so that the outer groove plate 100 can be as evenly stressed as possible. After the overall installation of the bracket is completed, the outer groove plate 100 is still a straight structure, ensuring that the roller can smoothly switch its working state. This design makes the connection between the outer groove plate 100 and the household appliance more stable.

[0035] Preferably, the top of the rib plate 140 is an extended plane with a certain horizontal width, so that the rib plate 140 forms a table-like structure. The inclination angle of the side wall of the rib plate 140 is greater than 50°, such as 55°, 60°, 75° or 90°, to increase the contact area with the bottom of the household appliance, thereby further strengthening the connection between the outer groove plate 100 and the bottom of the household appliance. Specifically, this inclination angle is the angle between the bottom of the rib plate 140 and its side wall.

[0036] Specifically, the area where the connection port 110 is located is flush with the upper surface of the rib plate 140. Compared with the scheme where the connection port 110 is recessed relative to the rib plate 140, the force transmission is more stable.

[0037] Optionally, as Figure 1 shown in the figure, the connection port 110 is a circular or kidney-shaped through hole, and the rib plate 140 is annular.

[0038] Optionally, as Figure 2 shown in the figure, the connection port 110 is a notch, and this notch communicates with the side of the outer groove plate 100. The rib plate 140 is U-shaped around the notch. Specifically, the surrounding here can be an incomplete surrounding.

[0039] Optionally, as Figure 3As shown, the rib plate 140 further has a necking portion 141. The necking portion 141 extends along the width direction of the outer groove plate 100. The width of the necking portion 141 is smaller than the width of the rib plate 140 corresponding to the connection port 110, and their heights are flush, so that the side edges of the rib plate 140 are fitted with the side edges of the bottom reinforcing ribs of the household appliance.

[0040] As other alternative solutions, the rib plate 140 can specifically be square, pear-shaped, trapezoidal, etc.

[0041] Preferably, the edges of the rib plate 140 are transitioned with arcs to reduce stress concentration.

[0042] Preferably, the rib plate 140 is formed by stamping the outer groove plate 100. As an alternative solution, the height L1 of the rib plate 140 is 3 mm to 8 mm, such as 3.2 mm, 4.5 mm, 6 mm, 7 mm, or 7.8 mm, etc. The thickness of the rib plate 140 is 1.0 mm to 2.5 mm, such as 1.1 mm, 1.2 mm, 1.5 mm, or 1.8 mm, etc.

[0043] Preferably, the height L1 of the rib plate 140 is 5 mm, which is adapted to the reinforcing ribs at the bottoms of most household appliances, and has a wider application range.

[0044] Specifically, one end of the outer groove plate 100 is hinged with a rotating handle. Since sufficient space for movement is left for the rotating handle, in the related art, the area of the outer groove plate 100 around the rotating handle is generally a flat thin plate structure, and the rotating handle generally has a certain weight by itself, which easily causes a large pressure on the hinged position, insufficient strength, and also easily affects its service life in the long run. To solve this problem, as Figure 4 、 5 shown, the mobile support of this embodiment further includes a reinforcing portion 160 that protrudes upward. The reinforcing portion 160 extends upward along the hinge point 150 of the rotating handle, and the height L2 of the reinforcing portion 160 is less than or equal to the height L1 of the rib plate 140 to prevent interference with the rib plate 140.

[0045] Optionally, the outer groove plate 140 can also form other convex ribs at the top to further increase the strength. The number of convex ribs is not limited and can be one or more.

[0046] Specifically, this embodiment provides a movable household appliance applying the above-mentioned mobile support, including an appliance body. The mobile support is installed on both sides of the bottom of the appliance body, and the rotating handle is hidden under the bottom of the appliance body. When the rotating handle is rotated, the rollers extend out of the inner groove plate for moving the appliance body.

[0047] More specifically, the bottom of the electrical appliance body has strip-shaped reinforcing ribs and feet located on the sides of the reinforcing ribs. The rib plate 140 is staggered from the reinforcing ribs, and the feet are installed in the connection port 110. The "strip-shaped" here may not necessarily be straight strip-shaped, but may also be other special-shaped strip-shaped.

[0048] Furthermore, the feet have screws, and the screws pass through the connection port 110, and nuts are used to fasten the moving bracket to the bottom of the electrical appliance body. Specifically, the nuts are installed on the bottom 130 of the outer groove plate 100.

[0049] Specifically, the rib plate 140 abuts against the bottom of the electrical appliance body, and the reinforcing ribs abut against the top plane of the outer groove plate 100.

[0050] In this application, the terms "install", "set", "provide", "connect", "link", "socket" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can also be internal communication between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
