Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock-absorbing washing machine technology, specifically a shock-absorbing washing machine foot pad. Background Technology
[0002] As an essential appliance in modern households, the stability of washing machine performance and the comfort of use have always been the focus of consumers' attention. During the use of a washing machine, especially during the spin-drying stage, the high-speed rotation inside the machine often generates significant vibration and noise. This not only affects the user experience but may also adversely impact the stability and lifespan of the washing machine.
[0003] To address this issue, traditional washing machine feet are typically made of elastic materials such as rubber or plastic, which offer some shock absorption. Especially when the washing machine is unevenly placed, it can affect the dynamic balance of the drum during high-speed rotation. Traditional feet are typically equipped with screws that connect to the washing machine, allowing for height adjustment and leveling. However, washing machines are usually placed inside a laundry cabinet on a balcony, making leveling and height adjustment difficult after installation. Utility Model Content
[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a shock-absorbing washing machine foot pad. Through a dual adjustment mechanism of screw and lead screw, the height and level of the washing machine can be easily adjusted even when it is installed in a confined space (such as inside a laundry cabinet). The structure is reasonably designed, and users can easily complete the installation and adjustment without professional tools, thus improving the ease of use and practicality of the product.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A shock-absorbing washing machine foot pad includes a main pad block. A limiting box is mounted on the top of the main pad block. A main support box is slidably connected inside the limiting box. A slider is mounted inside the main support box. Symmetrically arranged inclined surfaces are formed on the slider, with an inclination angle of 45°. The 45° angle ensures that two contact balls are at the same distance but opposite directions during displacement. A guide cylinder is symmetrically arranged on the top of the main support box. A connecting column is slidably connected inside the guide cylinder. A contact ball is fixedly connected to the bottom of the connecting column, and the contact ball abuts against the inclined surface of the slider. The inclined surface is smooth. A screw is driven to move towards a lower elevation, thereby pressing the contact ball on the connecting column at the lower elevation upwards, while the other contact ball moves downwards. Once the washing machine is leveled, the screw stops rotating.
[0007] More preferably, the contact ball abuts against the inclined surface of the slider, the inclined surface being a smooth surface. A screw is rotatably connected to one side of the slider, one end of the screw passing through the main support box and extending to the outside of the main support box. The screw is threadedly connected to the main support box, and a rotating handle is fixedly connected to the end of the screw located outside the main support box. A notch is opened on one side of the limiting box, through which the screw passes. When it is necessary to level the washing machine in the front and rear horizontal directions, the rotating rod is manually turned to drive the screw to rotate.
[0008] More preferably, the bottom of the inner wall of the limiting box is symmetrically rotatably connected to an adjusting plate. A through-hole is provided in the middle of the adjusting plate, and an adjusting block is disposed inside the through-hole. Rotating shafts are provided on both sides of the adjusting block, with the end of the rotating shaft furthest from the adjusting block rotatably connected to the inner wall of the through-hole. When the two adjusting blocks approach each other, the angle between the two adjusting plates decreases, thereby lifting the main support box and raising the height of this side of the washing machine for leveling.
[0009] More preferably, the limiting box is internally provided with a lead screw, which is threadedly connected to an adjusting block, and the two adjusting blocks are threadedly connected to the lead screw in opposite directions. Because the two adjusting blocks are threadedly connected to the lead screw in opposite directions, the two adjusting blocks are brought closer together.
[0010] More preferably, one end of the lead screw passes through the notch and extends out of the limiting box, and a turntable is fixedly connected to one end of the lead screw. When it is necessary to level or raise the washing machine in the left and right horizontal directions, the turntable in the foot pad at the lower position is manually rotated.
[0011] More preferably, the main body pad has multiple shock-absorbing holes inside. These holes effectively absorb vibration energy during washing machine operation, reducing noise.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model, through a dual adjustment mechanism of screw and lead screw, allows the washing machine to be easily adjusted in height and level even when installed in a confined space (such as inside a laundry cabinet). The structure is reasonably designed, and users can easily complete the installation and adjustment without professional tools, thus improving the ease of use and practicality of the product.
[0014] 2. The shock-absorbing holes in the main body pad of this utility model effectively absorb the vibration energy of the washing machine during operation and reduce noise. Attached Figure Description

[0024] like Figure 1-4As shown, a shock-absorbing washing machine foot pad includes a main pad 1. A limiting box 2 is mounted on the top of the main pad 1. A main support box 3 is slidably connected inside the limiting box 2. A slider 4 is mounted inside the main support box 3. Inclined surfaces 5 are symmetrically arranged on the slider 4, with an inclination angle of 45°. The 45° angle ensures that two contact balls 8 are at the same distance but opposite directions during displacement. A guide cylinder 6 is symmetrically arranged on the top of the main support box 3. A connecting column 7 is slidably connected inside the guide cylinder 6. A contact ball 8 is fixedly connected to the bottom of the connecting column 7. The contact ball 8 abuts against the inclined surface 5 of the slider 4. The inclined surface 5 is a smooth surface. A screw 9 is driven to move towards a lower elevation, thereby pressing the contact ball 8 on the connecting column 7 at the lower elevation to move upwards, while the other contact ball 8 moves downwards. When the washing machine is leveled, the screw 9 stops rotating.
[0025] More preferably, the contact ball 8 abuts against the inclined surface 5 of the slider 4, the inclined surface 5 being a smooth surface. A screw 9 is rotatably connected to one side of the slider 4. One end of the screw 9 passes through the main support box 3 and extends to the outside of the main support box 3. The screw 9 is threadedly connected to the main support box 3. A rotating handle 10 is fixedly connected to the end of the screw 9 located outside the main support box 3. A notch 11 is provided on one side of the limiting box 2, through which the screw 9 passes. When it is necessary to level the washing machine in the front and back horizontal directions, the rotating handle is manually turned to rotate the screw 9.
[0026] More preferably, the bottom of the inner wall of the limiting box 2 is symmetrically rotatably connected to an adjusting plate 12. A through-hole 13 is provided in the middle of the adjusting plate 12, and an adjusting block 14 is disposed inside the through-hole 13. A rotating shaft 15 is provided on both sides of the adjusting block 14, and the end of the rotating shaft 15 away from the adjusting block 14 is rotatably connected to the inner wall of the through-hole 13. When the two adjusting blocks 14 approach each other, the angle between the two adjusting plates 12 decreases, thereby lifting the main support box 3 and raising the height of this side of the washing machine for leveling.
[0027] More preferably, the limiting box 2 is provided with a lead screw 16 inside, and the lead screw 16 is threadedly connected to the adjusting block 14. The two adjusting blocks 14 are threaded in opposite directions to the lead screw 16. Because the two adjusting blocks 14 are threaded in opposite directions to the lead screw 16, the two adjusting blocks 14 are brought closer to each other.
[0028] More preferably, one end of the lead screw 16 passes through the notch 11 and extends out of the limiting box 2, and a turntable 17 is fixedly connected to one end of the lead screw 16. When it is necessary to level or raise the washing machine in the left and right horizontal directions, the turntable 17 in the foot pad at the lower position is rotated manually.
[0029] More preferably, the main body pad 1 has multiple shock-absorbing holes 18 inside. The shock-absorbing holes 18 inside the main body pad 1 effectively absorb the vibration energy during the operation of the washing machine, reducing noise.
[0030] Working principle:
[0031] Using this device, place the foot pads at the bottom of the washing machine. Two foot pads are placed symmetrically at the bottom of the washing machine. The connecting posts 7 inside the foot pads correspond to the four corners of the bottom of the washing machine, and the turntable 17 is kept facing the opening end of the washing machine, making subsequent adjustments more convenient.
[0032] When it is necessary to level or raise the washing machine, manually rotate the turntable 17 in the foot pad at the lower position. The lead screw 16 will rotate accordingly. Since the two adjusting blocks 14 are connected to the lead screw 16 in opposite directions, the two adjusting blocks 14 will move closer to each other, thereby reducing the angle between the two height adjustment plates 12. This will lift the main support box 3, raising the height of this side of the washing machine for leveling.
[0033] When the washing machine needs to be leveled in the front and back directions, manually turn the rotating rod to rotate the screw 9, thereby moving the screw 9 to a lower position, which in turn presses the contact ball 8 on the connecting post 7 at the lower position to move upward, while the other contact ball 8 moves downward. After the washing machine is leveled, stop rotating the screw 9.
[0034] When the washing machine is running, the shock-absorbing holes in the main body pad effectively absorb the vibration energy of the washing machine and reduce noise.
[0035] With its dual adjustment mechanism of screw and lead screw, the washing machine can be easily adjusted in height and level, even when installed in a confined space (such as inside a laundry cabinet). The reasonable structural design allows users to easily complete the installation and adjustment without the need for professional tools, improving the product's ease of use and practicality.
