In addition, ordinal numbers such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Furthermore, in order to more clearly demonstrate the core technical solution of the present utility model, the description of the well-known structure of the bevel gear is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the bevel gear can be without these structures.

[0031] like Figure 1-9 As shown, the utility model proposes a foot, including: a bracket 1, the bracket 1 is used to connect with a supported object, such as a washing machine or a washing machine bottom platform. The height direction is the height direction of the bracket 1, represented by Z in the figure; the length direction is the length direction of the bracket 1, represented by Y in the figure; the width direction is the width direction of the bracket 1, represented by X in the figure; the length direction of the bracket 1 is consistent with the length direction of the washing machine, the width direction of the bracket 1 is consistent with the width direction of the washing machine, and the height direction of the bracket 1 is the vertical direction.

[0032] The first bevel gear 2, the rotating shaft of the first bevel gear 2 is rotatably arranged on the bracket 1 along the height direction, and the first bevel gear 2 has an inner hole 21. The inner hole 21 is coaxially arranged with the first bevel gear 2. The screw rod 3, the screw rod 3 is rotatably arranged in the inner hole 21 along the height direction, and the first bevel gear 2 drives the screw rod 3 to rise and fall along the height direction after it rotates. A thread can be arranged on the inner wall of the inner hole 21, so that the screw rod 3 is threadedly connected with the inner hole 21, and the first bevel gear 2 drives the screw rod 3 to rise and fall after it rotates. Other transmission parts can also be used, and the transmission parts are threadedly connected with the screw rod 3, and the first bevel gear 2 drives the transmission parts to rotate, and the transmission parts drive the screw rod 3 to rise and fall.

[0033] The second bevel gear 4, the rotating shaft of the second bevel gear 4 is rotatably arranged on the bracket 1 along the length direction, and meshes with the first bevel gear 2. The second bevel gear 4 has a rotation slot 41 on the side away from the first bevel gear 2, and the rotation slot 41 is used to clamp the rotation clamp. After the rotation clamp is clamped into the rotation slot 41, the rotation clamp rotates to drive the second bevel gear 4 to rotate. Since the second bevel gear 4 meshes with the first bevel gear 2, it can drive the first bevel gear 2 to rotate. After the first bevel gear 2 rotates, it drives the screw 3 to rise and fall. In order to be able to rotate the second bevel gear 4, the bracket 1 cannot cover the rotation slot 41. During installation, the side with the rotation slot 41 is installed toward the user to facilitate the user to rotate the second bevel gear 4.

[0034] The rotating clamp and the rotating clamping slot 41 can be in any shape as long as they can drive the second bevel gear 4 to rotate, such as Figure 1 As shown, the rotating slot 41 is cross-shaped, and the rotating clamp (not shown in the figure) can be a long screwdriver.

[0035] Roller 5 is arranged on bracket 1. In order to prevent the roller from blocking the rotating slot 41, roller 5 and second bevel gear 4 are respectively located on both sides of first bevel gear 2 along the length direction. After screw 3 descends, it is supported on the ground to support the washing machine. After screw 3 rises, it leaves the ground, roller 5 contacts the ground, and roller 5 can roll. The rotating shaft of roller 5 can be rotated along the width direction of the washing machine, so that the washing machine can be pushed along the length direction.

[0036] In this embodiment, in order to solve the problem that the washing machine is difficult to move, a foot that is combined with a roller and driven by a bevel gear to lift a screw is provided. When the washing machine does not need to be moved, the rotating slot 41 is rotated to make the screw 3 contact with the ground to support the washing machine; when the washing machine needs to be moved, the rotating slot 41 is rotated to make the screw 3 leave the ground, and the roller 5 contacts the ground, and then the washing machine can be pushed. In the utility model, the horizontal rotation is converted into the lifting movement of the screw 3 by the second bevel gear 4 and the first bevel gear 2, which is convenient for users to adjust the lifting of the screw 3, especially for the case where the washing machine is embedded in the cabinet. For the washing machine embedded in the cabinet, the space for accommodating the washing machine is very small, and it is not easy to move the washing machine, and it is impossible to reach in and adjust the existing foot near the inside of the cabinet. However, the foot in the utility model can solve this problem. When installing, the rotating slots 41 of all the feet are facing the user. The user can use a long screwdriver to insert the rotating slot 41 on the foot inside the cabinet, and drive the second bevel gear 4 to rotate by the long screwdriver to adjust the height of the screw 3.

[0037] Further, if Figure 2 As shown, the bracket 1 is also provided with a socket 6, and the socket 6 is used to place a rotating card. The length of the rotating card can be the same as the length of the washing machine, and can also be adjusted according to the length of the washing machine, as long as it can be inserted into the rotating card slots 41 of all the feet. The rotating card can be a long screwdriver. Due to the long length of the long screwdriver, it is not easy to store and easy to lose, resulting in it being difficult to find when it is needed. In order to avoid these problems, a socket 6 is provided on the bracket 1. When the user does not need to use the rotating card, the rotating card can be inserted into the socket 6, and no additional storage space will be occupied. When the user needs to use the rotating card, it can be pulled out from the socket 6 for use, which is convenient for the user. Generally, two feet are provided along the length direction of the washing machine, and the rotating card can be inserted into the sockets 6 of the two feet.

[0038] Further, if Figure 1-5 As shown, the bracket 1 has an annular protrusion 13 along the length direction, an annular space is provided in the annular protrusion 3 , and the second bevel gear 4 is rotatably disposed in the annular space of the annular protrusion 13 .

[0039] Further, if Figure 7As shown in the figure, since it is difficult to process the threads on the first bevel gear 2, and if the threads are damaged, the first bevel gear 2 can only be replaced as a whole, and the maintenance cost is too high, so in this embodiment, the first bevel gear 2 is preferably driven by the transmission member 7 to drive the screw 3 to rise and fall. The inner hole 21 is a non-circular hole; the base also includes a transmission member 7, which is located in the inner hole 21. The transmission member 7 has a threaded hole along the height direction, and the screw 3 is inserted into the threaded hole. Figure 7 As shown, the inner hole 21 is a regular hexagonal hole, and the transmission member 7 can be a regular hexagonal nut, but this is not restrictive. Those skilled in the art can adjust the shapes of the inner hole 21 and the transmission member 7 as needed, as long as they can drive the screw 3 to rise and fall.

[0040] Further, if Figure 4-6 As shown, the foot also includes: a baffle 8, which is arranged on the bracket 1, and covers the top of the first bevel gear 2 in the height direction. The baffle 8 has a through hole 81, and the screw 3 passes through the through hole 81 in the height direction. In order to fix the first bevel gear 2 on the bracket 1 and prevent it from detaching from the bracket 1, the baffle 8 is arranged above the first bevel gear 2, and the baffle 8 can also prevent debris from falling into the bevel gear and affecting the transmission.

[0041] Further, if Figure 4-6 As shown, the bracket 1 has a clamping member 14, and the baffle 8 has a clamping portion 82, which is clamped below the clamping member 14 along the height direction; the clamping member 14 fixes the baffle 8 on the bracket 1 to prevent the baffle 8 from falling.

[0042] Further, if Figure 1 As shown, a connecting portion 15 is provided on the bracket 1 along the height direction, and the connecting portion 15 is used to connect with the supported object. A mounting hole can be provided on the connecting portion 15, and a bolt passes through the mounting hole to mount the bracket 1 on the washing machine.

[0043] Further, if Figure 8-9 As shown, the part of the bracket 1 on which the first bevel gear 2 and the second bevel gear 4 are installed is relatively complex and is more suitable for plastic material, but the supporting force of plastic is relatively weak. In order to improve the supporting force, the bracket is divided into a first support frame 11 and a second support frame 12. The first bevel gear 2 and the second bevel gear 4 are arranged on the first support frame 11, and the roller 5 is arranged on the second support frame 12. The first support frame 11 can be made of plastic material, and the second support frame 12 can be made of metal material with strong supporting force. The second support frame 12 can be arranged below the first support frame 11 to support the first support frame 11. The first support frame 11 and the second support frame 12 do not block the rotating slot 41 along the length direction.

[0044] Since the first bevel gear 2 and the second bevel gear 4 are arranged on the first support frame 11, the transmission member 7, the baffle 8 and the annular protrusion 13 are also arranged on the first support frame 11. The connecting portion 15 can be arranged on the second support frame 12. Since the first support frame 11 is located between the second support frame 12 and the washing machine, the connecting portion 15 can also fix the first support frame 11 to prevent the first support frame 11 from moving relative to the second support frame 12 in the height direction; at the same time, the connecting portion 15 can also be arranged at both ends of the second support frame 12 in the length direction to prevent the first support frame 11 from moving relative to the second support frame 12 in the length direction.

[0045] Further, if Figure 8-9 As shown, the first support frame 11 has a block 16, and the second support frame 12 has a mounting hole 17. After the block 16 is inserted into the mounting hole 17, the first support frame 11 is connected to the second support frame 12. The mounting hole 17 and the block 16 can also limit the movement of the first support frame 11 relative to the second support frame 12.

[0046] Those skilled in the art can adjust the number and position of the blocks 16 and the mounting holes 17 as needed. For example, a plurality of blocks 16 can be provided on the side of the first support frame 11 facing the second support frame 12 along the height direction, and a plurality of mounting holes 17 can be provided on the side of the second support frame 12 facing the first support frame 11. Each mounting hole 17 is provided corresponding to a block 16. After the block 16 is inserted into the mounting hole 17, the first support frame 11 is installed on the second support frame 12. The mounting hole 17 will limit the movement of the block 16, so that the first support frame 11 cannot move too much relative to the second support frame 12. Similarly, those skilled in the art can also provide mounting holes 17 on the first support frame 11 and blocks 16 on the second support frame 12. This does not deviate from the principle of the present utility model, and therefore will fall within the protection scope of the present utility model.

[0047] Further, if Figure 2 As shown, the foot also includes: a support sheet 9, which is arranged at one end of the screw rod 3 close to the ground. The contact area between the support sheet 9 and the ground is larger than the contact area between the screw rod 3 and the ground. The support sheet increases the contact area between the screw rod 3 and the ground, thereby improving the stability of the foot when supporting the washing machine.

[0048] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0049] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
