The adjustable footing 2 provided in this embodiment can achieve the purpose of more stably supporting and adjusting the height of the washing machine under the clamping cooperation of the upper sawtooth structures 2111 and the lower sawtooth structures 2112 of different pairs on the supporting rod 21.
Further, the elastic support ribs 23 at the outer periphery of the support rod 21 press against the inner wall of the mounting hole post 11. Preferably, the elastic supporting rib 23 is disposed on the lower section of the second side wall surface of the supporting rod 21, so as to avoid interfering with the arrangement of the lower sawtooth structure 2112, the inclined connecting section 231 of the elastic supporting rib 23 is connected at the bottom position of the lower section of the supporting rod 21, and gradually and outwards inclined from bottom to top, one end of the inclined connecting section 231 is connected on the supporting rod 21, the other end is connected with a vertical stopping section 232 which is vertically disposed, the outer wall surface of the vertical stopping section 232 is extruded and abutted on the inner peripheral wall of the mounting hole column 11, and the upper end of the vertical stopping section 232 is limited below the upper clamping rib 12.
Further, as shown in fig. 1, 2, 4, and 5, when the supporting leg 22 is supported on the ground in a horizontal state, the horizontal distance between the upper sawtooth structure 2111 of the supporting rod 21 and the corresponding lower sawtooth structure 2112 is d1. As shown in fig. 3, when the support rod 21 is adjusted to be in a vertical state, the horizontal distance between the upper sawtooth structure 2111 and the corresponding lower sawtooth structure 2112 is d2. The horizontal clearance distance between the inner side end walls of the upper clamping rib 12 and the lower clamping rib 12 is d3, wherein: d1 > d3 > d2.
Through the above design, as shown in fig. 2 and 5, when the supporting leg 22 is supported on the ground in a horizontal state, the upper saw-tooth structure 2111 and the lower saw-tooth structure 2112 of the adjustable foot 2 can be stably supported on the upper clamping rib 12 and the lower clamping rib 13. When the height of the support bar 21 needs to be adjusted, as shown in fig. 3, the support bar 21 is in a vertical state by rotating the support legs 22, so that the support bar 21 can smoothly push and pull the support bar 21 in a gap space between the upper clamping rib 12 and the lower clamping rib 13, so as to adjust the support height of the support bar 21.
As shown in fig. 1 and 4, the adjustable feet 2 are disposed on two sides of the base 1 of the washing machine, and the supporting legs 22 are in an outward-expansion shape due to the inclined arrangement between the supporting rods 21 and the supporting legs 22, when the supporting rods 21 are downwardly adjusted, that is, the supporting height of the supporting rods 21 is increased, the distance between the supporting legs 22 on two sides of the base 1 is gradually increased, so that the washing machine is more balanced and stable.
The working principle of the adjustable foot 2 according to the first embodiment of the present utility model and the washing machine according to the second embodiment will be described with reference to fig. 1 to 6.
As shown in fig. 1 and 2, the cross section of the support rod 21 provided by the utility model is in an oblique square structure, the left side and the right side are respectively provided with a lower sawtooth structure 2112 and an upper sawtooth structure 2111, and the inclination directions of the ribs of the upper sawtooth structure 2111 and the lower sawtooth structure 2112 are opposite. The maximum external diameter of the supporting rod 21 is smaller than the internal diameter of the mounting hole column 11 of the base 1, meanwhile, a lower clamping rib 13 is arranged on the left side of the mounting hole column 11 matched with the base 1 in a protruding mode, an upper clamping rib 12 is arranged on the right side of the mounting hole column in a protruding mode, and therefore the horizontal clamping faces 2111a/2112a of the upper sawtooth structure 2111 and the lower sawtooth structure 2112 of the supporting rod 21 can be clamped on the base 1 in a synchronous and reverse mode, and are not easy to fall off.
Referring to fig. 3, the adjustable foot 2 of the washing machine provided by the utility model is manually rotated and adjusted by a user, so that the supporting rod 21 and the mounting hole column 11 of the base 1 are in a vertical state. At this time, the user may adjust the support bar 21 up and down, and then rotate the support bar back to the position corresponding to the upper clamping rib 12/lower clamping rib 13 of the upper saw-tooth structure 2111/lower saw-tooth structure 2112 when the support bar is adjusted to a proper position.
As shown in fig. 3, when the adjustable foot 2 is to be adjusted, the body is lifted, and the support leg 22 is rotated by hand in a downward-rightward direction so that the direction of the central axis of the support bar 21 is parallel to the direction of the central axis of the mounting hole post 11 of the base 1, and at this time, the support bar 21 can be freely moved up and down. As shown in fig. 3 to 6, after the height is adjusted, the supporting leg 22 is rotated up and left again, so that the upper sawtooth structure 2111/lower sawtooth structure 2112 of the supporting rod 21 is correspondingly clamped with the upper clamping rib 12/lower clamping rib 13, and the machine body of the washing machine is put down to keep balance.
As shown in fig. 2, 3 and 5, the elastic supporting rib 23 provided on the right side of the supporting rod 21 is pressed against the inner wall of the mounting hole post 11 of the base 1, so as to prevent the supporting rod 21 from rotating by itself. Only the elasticity of the elastic supporting ribs 23 is needed to be overcome during manual adjustment. Meanwhile, the supporting rods 21 are obliquely arranged, and when the supporting rods 21 are downwards adjusted, the distance between the adjustable feet 2 positioned on two sides of the base 1 is increased, so that the washing machine is more balanced and stable.
The embodiments in the above examples may be further combined or replaced, and the examples are merely illustrative of preferred embodiments of the present utility model and not intended to limit the spirit and scope of the present utility model, and various changes and modifications made by those skilled in the art to the technical solution of the present utility model without departing from the design concept of the present utility model are all within the scope of the present utility model.
