Description

Technical Field

[0001] The utility model relates to the field of transfer devices for household appliances, in particular to a lifting and dragging base for household appliances. Background Art

[0002] In warehouses or homes, there are two main methods for moving heavy appliances, such as washing machines or refrigerators. One method is to use a forklift, which can effectively transfer heavy objects from one location to another but requires certain operating skills and expertise. The other method is manual handling, which, while simple and direct, requires a high level of operator strength and carries certain safety risks. Alternatively, a portable and easy-to-assemble lifting device can be used to transfer appliances. This method combines the advantages of the first two methods, requiring no specialized operating skills, reducing reliance on operator strength, and improving handling safety.

[0003] In the actual use of this lifting device, the operator needs to insert the device under the large household appliance, and then lift the large household appliance by operating the trailer for transfer. The key to this method lies in the design of the lifting device, which needs to have sufficient load-bearing capacity and stability to ensure the safety of the household appliance during transportation. The space at the bottom of household appliances is usually small, which requires the thickness of the lifting device to be as small as possible to adapt to the different spaces under the bottom of the household appliances to ensure the use effect. If the thickness of the lifting device is too large, it may not be able to be smoothly inserted under the household appliance, or it may cause damage to the bottom of the household appliance during transportation.

[0032] Reference Figures 1 to 7 In one embodiment of the present invention, a household appliance lifting and dragging base includes:

[0033] The strip-shaped main body 100 has a downwardly open chute 110 provided on its lower surface along its length. The chute 110 is provided with at least two hinge holes 111 spaced apart along its length and extending through its width. A vertical slot 112 is provided at the rear of the chute 110 along its length corresponding to the hinge holes 111. The vertical slot 112 extends to the lower surface of the main body 100.

[0034] A strip-shaped sliding member 200 is slidably disposed in the sliding groove 110. The sliding member 200 is provided with an inclined groove 210 corresponding to the vertical groove 112. The inclined groove 210 is arranged to be inclined downward and rearward from the upper portion of the sliding member 200 in the height direction and extends to the lower surface of the sliding member 200.

[0035] The flip wheel 300 includes a wheel frame 310 hinged to the hinge hole 111 at one end in the longitudinal direction, and a roller portion 320 is provided at the other end in the longitudinal direction of the wheel frame 310. The roller portion 320 includes a wheel axle 321 and a roller 322 mounted on the wheel axle 321. The wheel axle 321 is provided through the inclined slot 210 and the vertical slot 112.

[0036] The handle 400 has one end in the longitudinal direction hinged to the front end of the main body 100 to form a first hinge point, and the middle portion in the longitudinal direction of the handle 400 is connected to the front end of the sliding member 200;

[0037] When the handle 400 is pulled outward, the inclined slot 210 drives the flip wheel 300 to flip downward, and when the handle 400 is retracted inward, the flip wheel 300 is released by the inclined slot 210 and retracts upward.

[0038] In the prior art, there is still room for optimization of the thickness of the lifting device.

[0039] In the present invention, when the household appliance lifting and dragging base is in use, the up and down directions are fixed, and the front and rear directions are fixed, so a certain direction indication is provided in the manner of up, down and front and rear. During use, two household appliance lifting and dragging bases are used in conjunction with each other, respectively at the two ends of the opposite width of the household appliance. The household appliance lifting and dragging base includes a strip-shaped main body 100. A downwardly open slide 110 is provided on the lower surface of the main body 100 in the length direction. The cross section of the slide 110 can be U-shaped, and at least two hinge holes 111 that pass through the width direction are provided at intervals in the length direction of the slide 110. A vertical groove 112 is provided at the rear portion of the slide 110 corresponding to the hinge hole 111 in the length direction. The vertical groove 112 extends to the lower surface of the main body 100. The material of the main body 100 is preferably stainless steel, and can be stamped or bent.

[0040] A strip-shaped sliding member 200 slides within the slide groove 110. The sliding member 200 is made of stainless steel and can be stamped or bent. The sliding member 200 is provided with an inclined groove 210 corresponding to the vertical groove 112. The inclined groove 210 extends downward and rearward from the upper portion of the sliding member 200 in the height direction to the lower surface of the sliding member 200.

[0041] The flip wheel 300 includes a wheel frame 310 hinged to the hinge hole 111 at one end in the longitudinal direction, so that the wheel frame 310 can swing. A roller portion 320 is provided at the other end in the longitudinal direction of the wheel frame 310. When the wheel frame 310 swings, the roller portion 320 can change its position in the vertical direction. The roller portion 320 includes a wheel axle 321 and a roller 322 installed on the wheel axle 321. The roller 322 can be one or more as long as it does not interfere with the sliding of the sliding member 200. The wheel axle 321 is arranged to pass through the inclined groove 210 and the vertical groove 112. When the sliding member 200 slides inside the slide groove 110, the inclined groove 210 thereon can act on the wheel axle 321. During the action, the wheel axle 321 moves in the height direction of the vertical groove 112. The vertical slot 112 on the main body 100 extends to the lower surface of the main body 100, forming an open structure. The inclined slot 210 on the slider 200 also extends to the lower surface of the slider 200, forming an open structure. This increases the travel of the tilting wheel 300, meaning that the tilting wheel 300 can perform a greater downward tilting motion. This also increases the height of the entire appliance lifting and dragging base by approximately 1 cm, while reducing the thickness of the slider 200.

[0042] One end of the handle 400 is hinged to the front end of the main body 100, forming a first hinge point. The middle of the handle 400 is connected to the front end of the slider 200. This connection can be a hinge or a connecting rod, transmitting the rotation of the handle 400 to the slider 200 without interfering with the handle's rotation. The middle of the handle 400 is an indicator of position and is not limited to the exact middle.

[0043] When the handle 400 is pulled outward, the slider 200 slides forward in the slide groove 110, and the inclined groove 210 on the slider 200 drives the flip wheel 300 to flip downward, at which point the axle 321 moves downward in the vertical groove 112. When the handle 400 is retracted, the slider 200 slides rearward in the slide groove 110, and the inclined groove 210 on the slider 200 releases the flip wheel 300, causing it to flip upward, at which point the axle 321 moves upward in the vertical groove 112.

[0044] In summary, when the handle 400 is pulled outward, the inclined groove 210 on the sliding member 200 drives the flip wheel 300 to flip down, and at this time the wheel axle 321 moves downward in the vertical groove 112; when the handle 400 is retracted, the inclined groove 210 on the sliding member 200 releases the flip wheel 300 and flips up, and at this time the wheel axle 321 moves upward in the vertical groove 112; the vertical groove 112 on the main body 100 extends to the lower surface of the main body 100, forming an open structure, and the inclined groove 210 on the sliding member 200 extends to the lower surface of the sliding member 200, also forming an open structure; then the effective stroke of the flip wheel 300 is increased, that is, the downward flipping action of the flip wheel 300 can be executed to a greater extent, and on the premise that the thickness of the sliding member 200 can be reduced, the height that the entire household appliance lifting and dragging base can be lifted is increased by about 1 cm.

[0045] Reference Figure 2 、 4 and 7. In one embodiment, a horizontally arranged flat groove 211 is provided at the lower end of each inclined groove 210 in the longitudinal direction.

[0046] In this embodiment, the flat groove 211 is introduced to enable the flip wheel 300 to be stably supported when the household appliance lifting and dragging base is in the raised state. The specific length of the flat groove 211 is selected according to actual conditions.

[0047] Reference Figures 1 to 2 In one embodiment, there are two flip wheels 300 on the household appliance lifting and dragging base.

[0048] In this embodiment, the number of the turning wheels 300 is limited, which can provide stable support while reducing material consumption.

[0049] Reference Figures 1 to 2 In one embodiment, two rollers 322 are provided on the roller portion 320 , and the two rollers 322 are respectively located at both ends of the wheel shaft 321 in the length direction and outside the slide groove 110 .

[0050] In this embodiment, the roller portion 320 adopts a conventional structural shape, and is specifically provided with two rollers 322 , thereby forming a better supporting effect. In this case, the two rollers 322 need to be arranged outside the sliding groove 110 .

[0051] In one embodiment, a roller 322 is provided on the roller portion 320 . The roller 322 is located in the middle of the wheel shaft 321 in the length direction and in the sliding groove 110 .

[0052] In this embodiment, the rollers 322 are not exposed within the chute 110, thereby reducing the width of the entire appliance lifting and dragging base, providing better storage. In particular, the chute 110 protects the rollers 322, thereby reducing the possibility of adverse effects on the rollers 322 from the external environment. In this embodiment, the width of the rollers 322 is set relatively large to provide better support. For example, the width of the rollers 322 matches the width of the chute 110, so that the increased width does not affect rotation.

[0053] Reference Figures 2 to 3 In one embodiment, the front and rear ends of the main body 100 in the length direction are respectively a front support plate 120 and a rear support plate 130 , and the slide groove 110 is arranged between the front support plate 120 and the rear support plate 130 .

[0054] In this embodiment, the front support plate 120 facilitates the installation of the handle 400 and also serves as a support base to better support the home appliance. The rear support plate 130 also serves as a support base to better support the home appliance. Both the front support plate 120 and the rear support plate 130 can be flat plates, but are not limited to being purely flat plates and can also be provided with protrusions, depressions, holes, and other structures.

[0055] Reference Figures 2 to 3 In one embodiment, a first standing foot fixing hole 121 and a second standing foot fixing hole 131 are respectively provided on the front support plate 120 and the rear support plate 130, wherein at least one of the first standing foot fixing hole 121 and the second standing foot fixing hole 131 is a waist-shaped hole structure in the length direction of the main body 100.

[0056] In this embodiment, the appliance lifting and dragging base can be fixed to the bottom of the appliance through the first foot fixing hole 121 and the second foot fixing hole 131. At least one of the first foot fixing hole 121 and the second foot fixing hole 131 is a waist-shaped hole, which can adapt to a wider range of appliance models.

[0057] Reference Figures 2 to 3 In one embodiment, the first foot fixing hole 121 and the second foot fixing hole 131 are both provided with a guide opening 141 extending to the same side of the main body 100 .

[0058] In this embodiment, by providing the guide opening 141 , the main body 100 can be inserted into the foot at the bottom of the home appliance from one direction, and the foot at the bottom of the home appliance needs to be disassembled.

[0059] Reference Figures 1 to 7In one embodiment, the middle portion of the handle 400 in the longitudinal direction is hinged to the front end of the sliding member 200 in the longitudinal direction to form a second hinge point, wherein at least one of the first hinge point and the second hinge point is swingable.

[0060] In this embodiment, the connection between the middle portion of the handle 400 in the longitudinal direction and the front end of the slider 200 in the longitudinal direction is limited to a hinge, thereby simplifying the structure. Since the handle 400 has two hinge points, if both the first hinge point and the second hinge point are fixed, the handle 400 will not be able to rotate. Therefore, at least one of the first hinge point and the second hinge point can swing. For example, the first hinge point is fixed, while the second hinge point is swingable (there is a clearance fit between the hinge hole and the hinge axis, for example, the hinge hole is a long strip); or the first hinge point is swingable, while the second hinge point is fixed.

[0061] In one embodiment, the middle portion of the handle 400 in the length direction is connected to the front end of the sliding member 200 in the length direction via a connecting rod.

[0062] In this embodiment, the swing of the handle 400 is compensated by the connecting rod structure, so that the handle 400 can smoothly apply force to the sliding member 200. Specifically, the two ends of the connecting rod in the length direction are connected to the handle 400 and the sliding member 200 respectively.

[0063] In summary, the household appliance lifting and dragging base provided by the present invention has the following characteristics: when the handle 400 is pulled outward, the inclined groove 210 on the sliding member 200 drives the flip wheel 300 to flip down, and at this time the wheel axle 321 moves downward in the vertical groove 112; when the handle 400 is retracted, the inclined groove 210 on the sliding member 200 releases the flip wheel 300 and flips up, and at this time the wheel axle 321 moves upward in the vertical groove 112; the vertical groove 112 on the main body 100 extends to the lower surface of the main body 100, forming an open structure, and the inclined groove 210 on the sliding member 200 extends to the lower surface of the sliding member 200, also forming an open structure; then the effective stroke of the flip wheel 300 is increased, that is, the downward flipping action of the flip wheel 300 can be executed to a greater extent, and the height that the entire household appliance lifting and dragging base can be lifted is increased by about 1 cm under the premise that the thickness of the sliding member 200 can be reduced.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
