Description

Technical Field

[0001] The utility model belongs to the technical field of washing machine mobility, and in particular relates to a washing machine mobile base. Background Art

[0002] A washing machine is a cleaning mechanical appliance used to wash clothes. It is a must-have in modern families. It is simple, convenient, time-saving and labor-saving to use. In some old communities, no special location for washing machines was reserved at the beginning of construction, and the bathroom area is small. The washing machine needs to be moved frequently during use. The weight of the washing machine is between 40kg and 80kg, which is relatively heavy and inconvenient to move. At the same time, when the washing machine is damaged, it also needs to be moved to a spacious and bright place to facilitate maintenance personnel to carry out maintenance work.

[0003] Chinese patent CN206495069U discloses a mobile base for a washing machine, including a circular chassis, fixed feet, adjusting screws, universal wheels and a level. Although the mobile base for a washing machine disclosed in the above patent is convenient for moving the washing machine, when it is moved to a specified position, it is necessary to screw the adjusting screw downward to drive the fixed feet to contact the ground. Due to the weight of the base plus the weight of the washing machine, a large force is required when screwing the adjusting screw, which is inconvenient for elderly people living alone. In addition, the base lacks a mechanism for limiting and damping the washing machine. When the washing machine is working, the washing machine and the base collide rigidly, which easily causes the washing machine to fall from the base and cause damage. Therefore, a technical measure is proposed to solve the problems that a large force is required when screwing the adjusting screw downward, which is inconvenient to use, and when the washing machine is working, the washing machine and the base collide rigidly, which easily causes the washing machine to fall from the base and cause damage. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a mobile base for a washing machine, aiming to solve the problems in the prior art that when screwing the adjusting screw downward, a large amount of force is required, which is inconvenient to use, and when the washing machine is working, a rigid collision occurs between the washing machine and the base, which can easily cause the washing machine to fall from the base and cause damage.

[0005] In order to solve the above technical problems, the utility model provides a mobile base for a washing machine, comprising a first base, a second base, a third base and a fourth base, wherein the first base, the second base, the third base and the fourth base are L-shaped, and a size adjustment component is connected between the first base, the second base, the third base and the fourth base, and a limited shock-absorbing component is installed at the corners of the upper surfaces of the first base, the second base, the third base and the fourth base, and a shift fixing component is installed at the corners of the lower surfaces of the first base, the second base, the third base and the fourth base. Thanks to the setting of the limited shock-absorbing component, when the washing machine collides rigidly with the base during operation, the washing machine is prevented from falling off the base and causing damage. At the same time, thanks to the setting of the shift fixing component, the washing machine can be easily moved and fixed.

[0006] Furthermore, the size adjustment component includes a round rod, which is fixedly installed at the center position of the side of the first base, the second base, the third base, and the fourth base. The round rod is rotatably connected to a first screw rod, and the first screw rod is threadedly connected to the side of the first base, the second base, the third base, and the fourth base away from the round rod. Thanks to the setting of the size adjustment component, it can adapt to washing machines of different sizes and improve the applicability of the base.

[0007] Furthermore, the outer sliding sleeve of the round rod is provided with a screw ring, and the screw ring is threadedly connected to the first screw rod. The first base, the second base, the third base and the fourth base are provided with grooves adapted to the screw ring. Thanks to the setting of the screw ring, the size adjustment component can be easily fixed.

[0008] Furthermore, the limiting shock-absorbing assembly includes a limiting plate, the lower end of which is fixedly mounted on the corners of the upper surfaces of the first base, the second base, the third base and the fourth base, a hollow box is installed at the center of the surface of the limiting plate, a clamping block is engaged with the hollow box, two groups of symmetrically distributed springs are installed on the side of the clamping block close to the limiting plate, a shock-absorbing pad is installed on the side of the clamping block away from the limiting plate, the clamping block is slidably connected to the hollow box, the spring is inside the hollow box, and one end of the spring away from the clamping block is fixedly mounted inside the hollow box. Thanks to the coordinated use of the spring and the shock-absorbing pad, the absorption of the collision force of the washing machine is improved.

[0009] Furthermore, the shift fixing assembly includes a fixing rod, which is fixedly installed at the corners of the lower surfaces of the first base, the second base, the third base and the fourth base. The fixing rod is rotatably connected to a vertical rod, a bottom plate is fixedly installed at the lower end of the vertical rod, two groups of symmetrically distributed mounting plates are installed on the lower surface of the bottom plate, the mounting plate is rotatably connected to a connecting rod, and a moving wheel is fixedly installed in the middle position of the connecting rod. Thanks to the rotatable connection between the fixing rod and the vertical rod, it is convenient to turn the moving wheel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can adapt to washing machines of different sizes by setting the size adjustment component, improve the practicality of the base, and increase the distance between the first base, the second base, the third base, and the fourth base by rotating the first screw, so as to adapt to different washing machines;

[0014] By setting the limit shock-absorbing assembly, when the washing machine collides with the base rigidly during operation, the washing machine is prevented from falling off the base and causing damage. The impact force of the washing machine shaking is absorbed by the compression shock-absorbing pad and the spring, and the shaking amplitude of the washing machine is reduced. In addition, the limit plate plays a role in limiting and fixing the washing machine, which can effectively prevent the washing machine from falling off the base.

[0015] By setting the shift fixing component, when it is necessary to move, by turning the first knob and the second knob, the second screw rod releases the limit on the vertical rod and the third screw rod releases the limit on the connecting rod, thereby releasing the limit on the shift fixing component. At this time, the washing machine and the base can be pushed. When reaching the specified position, the first knob and the second knob are turned to make the second screw rod and the third screw rod limit the shift fixing component again. The washing machine can be fixed without using a lot of force, which is convenient to use, especially for the elderly. BRIEF DESCRIPTION OF THE DRAWINGS

The first base 1, the second base 5, the third base 6, and the fourth base 7 are provided with grooves adapted to the screw ring 202.

[0027] Reference Figure 1 , Figure 3 As shown, the limiting shock absorbing assembly 3 includes a limiting plate 302, the lower end of the limiting plate 302 is fixedly installed at the corners of the upper surfaces of the first base 1, the second base 5, the third base 6, and the fourth base 7, a hollow box 301 is installed at the center position of the surface of the limiting plate 302, and a clamping block 305 is engaged with the hollow box 301. Two groups of symmetrically distributed springs 303 are installed on the side of the clamping block 305 close to the limiting plate 302, and a shock absorbing pad 304 is installed on the side of the clamping block 305 away from the limiting plate 302. The clamping block 305 is slidably connected to the hollow box 301, the spring 303 is inside the hollow box 301, and the end of the spring 303 away from the clamping block 305 is fixedly installed inside the hollow box 301.

[0028] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the shift fixing assembly 4 includes a fixing rod 401, which is fixedly installed at the corners of the lower surfaces of the first base 1, the second base 5, the third base 6, and the fourth base 7. The fixing rod 401 is rotatably connected to a vertical rod 405, and a bottom plate 402 is fixedly installed at the lower end of the vertical rod 405. Two groups of symmetrically distributed mounting plates 403 are installed on the lower surface of the bottom plate 402. The mounting plate 403 is rotatably connected to a connecting rod 411, and a moving wheel 404 is fixedly installed at the middle position of the connecting rod 411. A second screw 407 is threaded through the side surface of the fixing rod 401, and the second screw A first knob 408 is installed at one end of the rod 407 away from the fixed rod 401, a first fixing hole 406 is opened at the upper end of the vertical rod 405, the first fixing hole 406 and the second screw 407 are at the same height, the second screw 407 is adapted to the first fixing hole 406, a third screw 410 is threaded through one end of the upper surface of the bottom plate 402, the upper end of the third screw 410 is connected to the second knob 409, a second fixing hole 412 is opened on the connecting rod 411, the second fixing hole 412 is inside the mounting plate 403, and the third screw 410 is adapted to the second fixing hole 412.

[0029] In actual use of the base, first measure the bottom size of the washing machine, and then adjust the base size to match the washing machine through the size adjustment component 2 (adjust the distance between the limit damping components 3 to match the length and width of the washing machine), specifically, rotate the first screw 203, the first screw 203 is rotated and unscrewed from the internal threads of the first base 1, the second base 5, the third base 6, and the fourth base 7 that are threaded together, and the distance between the first base 1, the second base 5, the third base 6, and the fourth base 7 increases. When the base size matches the washing machine, the screw ring 202 is pulled out from the groove and slides along the round rod 201 to the first screw 203, and then the screw ring 202 is rotated to the surface where the first screw 203 contacts the first base 1, the second base 5, the third base 6, and the fourth base 7, thereby completing the fixing of the base size.

[0030] Then, the washing machine is placed in the base. When the washing machine enters the base, the limit shock-absorbing assembly 3 plays a preliminary limit role. When the washing machine is working, the washing machine will shake, and thus will collide with the limit shock-absorbing assembly 3. When the washing machine collides and squeezes the shock-absorbing pad 304, the shock-absorbing pad 304 retracts, and the retraction of the shock-absorbing pad 304 drives the block 305 to retract. The block 305 retracts and slides along the hollow box 301. The sliding of the block 305 compresses the spring 303. The spring 303 is compressed to absorb the collision force of the washing machine, and the shaking amplitude of the washing machine is reduced. The shock-absorbing pad 304 also absorbs part of the collision force. At the same time, the limit plate 302 plays a role in limiting and fixing the washing machine.

[0031] When the washing machine needs to be moved, first turn the first knob 408. The first knob 408 rotates to drive the second screw rod 407 to disengage from the vertical rod 405, and the second screw rod 407 disengages from the vertical rod 405, so that the second screw rod 407 releases the fixation of the first fixing hole 406. At this time, the restriction on the directional rotation of the displacement fixing component 4 is released (the moving wheel 404 can rotate in the direction, but cannot move forward). Then turn the second knob 409. The second knob 409 rotates to drive the third screw rod 410 to move upward. The third screw rod 410 moves upward and disengages from the second fixing hole 412. At this time, the restriction on the horizontal movement of the displacement fixing component 4 is released, and then the washing machine is pushed to drive the moving wheel 404 to move, and the washing machine is moved to a designated place for placement or maintenance. When the designated place is reached, the first knob 408 is turned to drive the end of the second screw rod 407 to enter the first fixing hole 406, and the second knob 409 is turned to drive the third screw rod 410 to enter the second fixing hole 412, thereby completing the fixation of the base.
