Description

Technical Field

[0001] This utility model relates to the field of furniture transfer fixtures, and in particular to a home appliance lifting and transfer device that is length-adaptable and provides stable support. Background Technology

[0002] For heavy appliances (such as washing machines or refrigerators) that are difficult to move in warehouse environments or home settings, there are two main methods: one is to use a forklift, and the other is to rely on manual lifting. In addition, there is another method: using a simple lifting device compatible with the appliance. Current lifting devices are usually non-fixed; when using them, the lifting device needs to be inserted into the bottom of the appliance, and then the appliance is lifted using a lever mechanism to complete the transfer.

[0003] Due to the complexity of the bottom structure of home appliances, the insertion process of lifting devices may encounter difficulties or even be impossible. Therefore, transfer devices that are permanently attached to the bottom of home appliances have practical application value. During the transfer process, the lifting device only needs to be activated, and after the transfer is completed, it can be released. Therefore, designing a rational transfer device that can be permanently fixed to the bottom of home appliances while providing superior performance has become an urgent need. Some models of home appliances have protruding reinforcing ribs (reinforcing bends or square tubes) along the width direction at the front and / or rear ends to enhance structural strength or facilitate cleaning. The presence of these reinforcing ribs affects the placement and operation of the transfer device. Therefore, the presence of these reinforcing ribs makes the fit of the lifting device more stringent in terms of position and size, reducing its adaptability. Utility Model Content

[0004] The main purpose of this utility model is to provide a home appliance lifting and transfer device that is length-adaptable and provides stable support, in order to solve the problem that when the extension plate is used to improve the adaptability of the lifting and transfer device, the structure of the extension plate is unstable and it is prone to bending.

[0005] To achieve the above objectives, this utility model provides a length-adaptive and stable appliance lifting and transfer device, comprising:

[0006] A motherboard in the shape of a straight plate includes a front plate, a connecting rib and a rear plate connected in sequence, wherein the upper surface of the front plate and / or the rear plate is provided with a transverse groove extending through its width direction;

[0007] An extension plate includes an upwardly opening slotted plate and a wing plate connected to at least one end of the slotted plate in the width direction. The slotted plate wraps upwardly around the rear end of the main plate in the length direction. The two ends of the slotted plate in the width direction respectively form a slidable groove with the two ends of the main plate in the width direction. The upper surface of the wing plate is flush with the upper surface of the main plate. The side of the main plate is provided with an ear support plate corresponding to the lower surface of the wing plate. The side of the slotted plate is provided with a hollow slit corresponding to the ear support plate. When the extension plate slides, the ear support plate slides within the hollow slit.

[0008] Multiple movable wheels are arranged below the connecting rib and spaced apart in length, and clearance windows are provided on the groove plate at the positions corresponding to the movable wheels;

[0009] A skateboard is slidably disposed below the connecting rib along its length, and multiple drive components are provided on the skateboard corresponding to the multiple movable wheels;

[0010] A lever, hinged to the front plate and connected to one end of the slide plate near the front plate;

[0011] During the reciprocating motion of the lever, the slide plate reciprocates while the drive member presses down and releases the movable wheel.

[0012] Furthermore, the connecting rib is provided with fixed shafts on both sides that form a sliding groove with the slide plate, and the two ends of the groove plate are respectively provided with a first elongated groove that forms a sliding groove with the fixed shaft.

[0013] Furthermore, the wing plate is provided with an ear hole at the front end of the cutout, which is connected to the cutout and provides a passage space for the ear tray in terms of thickness.

[0014] Furthermore, the movable wheel includes a hinge shaft and a swing frame. A plurality of the hinge shafts are spaced apart in the length direction of the connecting rib. The hinge shafts are fixed across the width direction of the connecting rib. The swing frame is hinged to the hinge shaft and has a roller connected to its free end. The driving member is a protrusion provided on the bottom of the slide plate.

[0015] Furthermore, a second elongated groove is provided at each end of the width of the groove plate, and the hinge shaft forms a shaft-groove sliding fit with the second elongated groove.

[0016] Furthermore, the appliance lifting and transfer device also includes a fixing pin, which passes through the second elongated groove and connects to the main board to fix the extension plate.

[0017] Furthermore, the movable wheel portion also includes an elastic element, which is connected to the hinge shaft to press the swing frame upward.

[0018] Furthermore, one end of the lever in the length direction is hinged to the front plate plane to form a first hinge point, and the middle part of the lever in the length direction is connected to one end of the slide plate near the front plate, so that the lever can rotate based on the first hinge point.

[0019] Furthermore, the front plate and the wing plate are respectively provided with a front through hole and a rear through hole.

[0020] Furthermore, the front through hole and / or the rear through hole are oblong holes.

[0021] This utility model provides a length-adaptive and stable appliance lifting and transfer device. When the lever operates, the movable wheel is pressed down, lifting the appliance, which serves as the base for rolling. When the lever operates, the movable wheel is released, lowering the appliance. The horizontal groove corresponds to the protruding structure on the bottom of the appliance, allowing the rest of the main board to fit snugly against the bottom of the appliance. The sliding extension plate allows the main board and extension plate to accommodate appliances of more sizes. The ear plate on the main board supports the extension plate while also limiting the shrinkage of the perforated seam, ultimately reducing the possibility of the extension plate bending or undergoing other deformations.

[0032] Reference Figures 1 to 6 In one embodiment of this utility model, a home appliance lifting and transfer device with adaptable length and stable support includes:

[0033] The main board 100 is in the shape of a straight plate and includes a front plate 110, a connecting rib 120 and a rear plate 130 connected in sequence. The upper surface of the front plate 110 and / or the rear plate 130 is provided with a transverse groove 111 that runs through its width direction.

[0034] The extension plate 200 includes an upwardly opening groove plate 210 and a wing plate 220 connected to at least one end of the groove plate 210 in the width direction. The groove plate 210 wraps upwardly around the rear end of the main plate 100 in the length direction. The two ends of the groove plate 210 in the width direction respectively form a shaft groove for sliding engagement with the two ends of the main plate 100 in the width direction. The upper surface of the wing plate 220 is flush with the upper surface of the main plate 100. The side of the main plate 100 is provided with an ear support plate 140 corresponding to the lower surface of the wing plate 220. The side of the groove plate 210 is provided with a hollow slit 221 corresponding to the ear support plate 140. When the extension plate 200 slides, the ear support plate 140 slides in the hollow slit 221.

[0035] Multiple movable wheel sections 300 are arranged below the connecting rib 120 and spaced apart in length. A clearance window 211 is provided on the groove plate 210 at the position corresponding to the movable wheel section 300.

[0036] The slide plate 400 is slidably disposed below the connecting rib 120 along the length direction, and multiple driving components are provided on the slide plate 400 corresponding to the multiple movable wheel portions 300;

[0037] A lever 500 is hinged to the front plate 110 and connected to one end of the slide plate 400 near the front plate 110;

[0038] During the reciprocating motion of the lever 500, the slide plate 400 reciprocates while the drive member presses down and releases the movable wheel 300.

[0039] In the existing technology, the presence of reinforcing ribs makes the adaptation of the lifting device to position and size more stringent, resulting in a decrease in adaptability.

[0040] In this utility model, the appliance lifting and transferring device is fixed in the up and down directions during use, thus providing directional indication in an up-and-down manner. The main board 100, which is generally straight, includes a front plate 110 and a rear plate 130. The front plate 110 and the rear plate 130 are respectively used to connect to the front and rear corners of the appliance. A connecting rib 120 with a downward-facing open cross-section is connected between the front plate 110 and the rear plate 130 at one end in the width direction. The connecting rib 120 provides a structural connection and a foundation for the subsequent installation of the sliding plate 400. It should be noted that the names of the front plate 110, connecting rib 120, and rear plate 130 refer to their positions and do not indicate that they are separate and independent structures. In fact, there may not be a clear boundary between them; for example, the main board 100 may be a one-piece molded structure. The cross-section of the connecting rib 120 is a fully open or partially open frame structure, and a sliding groove is formed on its lower surface. Considering that some home appliances have protruding reinforcing ribs in the width direction of the front and / or rear ends for structural strength or cleaning purposes, the presence of these reinforcing ribs affects the placement of the mainboard 100. Therefore, a horizontal groove 111 is introduced. This groove 111 corresponds to the aforementioned reinforcing ribs, allowing the remaining part of the mainboard 100 to fit snugly against the bottom of the home appliance. To improve compatibility, the width of the horizontal groove 111 can be specifically increased, thereby expanding the range of home appliance models and types that the appliance lifting and transfer device can accommodate. The horizontal groove 111 is preferably integrally formed on the front panel 110 or the rear panel 130.

[0041] The extension plate 200 includes an upwardly opening slotted plate 210 and a wing plate 220 connected to at least one end of the slotted plate 210 in the width direction. The slotted plate 210 provides a fixing effect, and the wing plate 220 provides support for the appliance. The slotted plate 210 wraps upward around the rear end of the main board 100 in the length direction, and the two ends of the slotted plate 210 form a slidable groove with the two ends of the main board 100 in the width direction. The top surface of the slotted plate 210 is recessed or flush with the upper surface of the main board 100. The extension plate 200 and the main board 100 are fitted together by a groove fit structure. The groove fit structure includes a fixing shaft and an oblong hole, so the fixing position of the extension plate 200 on the main board 100 is adjustable. Multiple groove fit structures can be set to improve stability. The position of the groove fit structure can be on the rear plate 130 or the connecting rib 120. The specific overall structure of the extension plate 200 is not limited, as long as it can achieve fixing. The specific form of the shaft-groove mating structure can be varied. The groove structure can be set on the extension plate 200 or the main plate 100, and the shaft structure can be set on the main plate 100 or the extension plate 200 accordingly; or the shaft structure can be an external bolt, and both the extension plate 200 and the main plate 100 can be provided with groove structures to achieve the shaft-groove mating structure. Increasing the number of mating structures between the extension plate 200 and the main plate 100 can further improve the support stability of the extension plate 200 on the main plate 100. The extension plate 200 and the connecting rib 120 are respectively provided with two shaft-groove mating structures at both ends in the width direction, thereby achieving a stable support structure. The upper surface of the wing plate 220 is flush with the upper surface of the main plate 100, so that the wing plate 220 can form a stable support with the main plate 100. Moreover, the above structural characteristics of the extension plate 200 ensure that there is no blind spot in the length adjustment process during the sliding of the extension plate 200 on the main plate 100, that is, the upper surface of the extension plate 200 will not exceed the upper surface of the main plate 100. The motherboard 100 has an ear support plate 140 on its side corresponding to the lower surface of the wing plate 220. The groove plate 210 has a corresponding perforated slot 221 on its side. When the extension plate 200 slides, the ear support plate 140 slides within the perforated slot 221. While supporting the extension plate 200, the ear support plate 140 on the motherboard 100 also restricts the contraction of the perforated slot 221, thus reducing the possibility of the extension plate 200 bending or undergoing other deformations.

[0042] Multiple movable wheels 300 are spaced apart along the length of the main board 100. The structure of the movable wheels 300 can be varied, depending on whether they can retract and lower on the main board 100.

[0043] The slide plate 400 is slidably disposed in the connecting rib 120 along its length, and multiple driving components are provided on the slide plate 400 corresponding to the multiple movable wheel portions 300. The structure of the driving components can also be varied, such as a protruding structure or a groove structure, depending on whether it can act on the movable wheel portions 300. This will be described in detail in subsequent embodiments.

[0044] The levering process performed on the lever 500 can be in the horizontal direction or in the vertical plane. During the reciprocating levering process, the slide plate 400 reciprocates, and the drive component presses down and releases the movable wheel 300, causing it to flip upwards. When the movable wheel 300 is pressed down, the appliance is lifted and can be dragged; when the movable wheel 300 is released, the appliance is lowered. In a specific embodiment, one end of the lever 500 in the longitudinal direction is hinged to the front plate 110 plane to form a first hinge point, and the middle part of the lever 500 in the longitudinal direction is connected to the end of the slide plate 400 near the front plate 110; thus, the lever 500 can rotate based on the first hinge point. The connection between the middle portion of the lever 500 along its length and the slide plate 400 can be varied. For example, the middle portion of the lever 500 along its length can be hinged to one end of the slide plate 400 near the front plate 110 to form a second hinge point. At least one of the first and second hinge points is swayable, thus not restricting the rotation of the lever 500. Alternatively, the middle portion of the lever 500 along its length can be connected to the slide plate 400 via a connecting rod. The purpose of the lever 500 is simply to allow lever operation of the slide plate 400 by operating the lever 500. The middle portion along the length of the lever 500 is not limited to the exact center along its length, but only requires that it be offset from one end along the length of the lever 500, so that the lever 500 can rotate.

[0045] In summary, when the lever 500 operates the movable wheel 300 and presses it down, the appliance is lifted up, and the movable wheel 300 can serve as the basis for rolling; when the lever 500 operates the movable wheel 300 and releases it, the appliance is lowered; through the transverse groove 111 corresponding to the protruding structure at the bottom of the appliance, the rest of the main board 100 can fit snugly with the bottom of the appliance; through the sliding setting of the extension plate 200, the whole formed by the main board 100 and the extension plate 200 can adapt to more sizes of appliances, and there is no blind spot in the length adjustment process when the extension plate 200 slides on the main board 100; while the ear plate 140 on the main board 100 supports the extension plate 200, the ear plate 140 also restricts the contraction of the hollow seam 221, and ultimately reduces the possibility of the extension plate 200 bending or other deformation.

[0046] Reference Figures 1 to 4 In one embodiment, the connecting rib 120 is provided with fixed shafts 121 on both sides that form a sliding groove with the slide plate 400, and the groove plate 210 is provided with a first elongated groove 212 at both ends of its width that forms a sliding groove with the fixed shaft 121.

[0047] In this embodiment, considering the need for smooth sliding of the slide plate 400, a shaft groove sliding fit can also be provided between the connecting rib 120 and the slide plate 400. A fixed shaft 121 (not limited to one) spanning the width direction is provided on the connecting rib 120, and a waist hole corresponding to the fixed shaft 121 is provided on the slide plate 400. Thus, the slide plate 400 can slide under the guidance of the fixed shaft 121 based on the waist hole. Therefore, by sharing the fixed shaft 121, a first elongated groove 212 is provided at both ends of the width of the groove plate 210 to form a shaft groove sliding fit with the fixed shaft 121. This allows the two ends of the width of the groove plate 210 to form a shaft groove sliding fit with the main plate 100 without increasing the structural complexity.

[0048] Reference Figures 1 to 4 In one embodiment, the wing plate 220 is provided with an ear hole 222 corresponding to the front end of the cutout 221, which is connected to the cutout 221 and provides a thickness passage space for the ear pad 140.

[0049] In this embodiment, considering that the slot plate 210 wraps upwards around the rear end of the main board 100 along its length, the upper surface of the wing plate 220 is flush with the upper surface of the main board 100, and the ear support plate 140 on the side of the main board 100 is located on the lower surface of the wing plate 220, the installation process of the extension plate 200 is relatively difficult, and it may even require some deformation of the extension plate 200 before it can be installed in place. An ear hole 222 is added close to the cutout 221, allowing the ear support plate 140 to complete the installation process smoothly. Specifically, during the installation process, the extension plate 200 initially wraps around the underside of the main board 100 but is not fully inserted, with the ear support plate 140 above the wing plate 220. When the extension plate 200 slides until the ear support plate 140 aligns with the ear hole 222, the ear support plate 140 passes through the ear hole 222 and moves to the underside of the wing plate 220. As the slot plate 210 slides further, the extension plate 200 finally completes the installation process.

[0050] Reference Figures 1 to 5 In one embodiment, the movable wheel portion 300 includes a hinge shaft 310 and a swing frame 320. A plurality of hinge shafts 310 are spaced apart along the length of the connecting rib 120. The hinge shafts 310 are fixed across the width of the connecting rib 120. The swing frame 320 is hinged to the hinge shaft 310 and has a roller 330 connected to its free end. The driving member is a protrusion 410 disposed at the bottom of the slide plate 400.

[0051] In this embodiment, a structural form of movable wheel section 300 is proposed, in which multiple hinge shafts 310 are spaced apart along the length direction of connecting rib 120. The hinge shafts 310 are disposed in sliding grooves. The hinge shafts 310 are fixed across the width direction of connecting rib 120, thus forming a stable support. Swing frame 320 is hinged to hinge shaft 310, and rollers 330 are provided at the free end of swing frame 320. Thus, the movable wheel section 300 can swing with hinge shaft 310 as the base. When the movable wheel section 300 swings out of connecting rib 120, the appliance is lifted, and the rollers 330 can serve as the base for rolling; when the movable wheel section 300 retracts into connecting rib 120, the appliance is lowered.

[0052] Reference Figures 1 to 4 In one embodiment, a second elongated groove 213 is provided at each end of the width of the groove plate 210, and the hinge shaft 310 forms a shaft-groove sliding fit with the second elongated groove 213.

[0053] In this embodiment, a sliding fit between the hinge shaft 310 and the groove plate 210 avoids the hinge shaft 310 while also forming a sliding fit between the shaft and the groove, providing a basis for the sliding and fixing of the extension plate 200.

[0054] Reference Figures 1 to 4 In one embodiment, the appliance lifting and transfer device further includes a fixing pin 600, which passes through the second elongated groove 213 and is connected to the main board 100 to fix the extension plate 200.

[0055] In this embodiment, the introduction of the fixing nail 600 avoids the risk of the extension plate 200 sliding unexpectedly.

[0056] Reference Figures 1 to 4 In one embodiment, the movable wheel portion 300 further includes an elastic element connected to the hinge shaft 310 to press the swing frame 320 upward.

[0057] In this embodiment, the elastic element can take various forms, such as a torsion spring. The elastic element is disposed on the hinge shaft 310 and presses the swing frame 320 toward the connecting rib 120, so that the movable wheel 300 will not sag naturally in the free state.

[0058] Reference Figures 1 to 4 In one embodiment, one end of the lever 500 in the length direction is hinged to the plane of the front plate 110 to form a first hinge point, and the middle part of the lever 500 in the length direction is connected to one end of the slide plate 400 near the front plate 110, so that the lever 500 can rotate based on the first hinge point.

[0059] In this embodiment, the lever 500 rotates horizontally, resulting in a smaller overall thickness and operating dimension of the appliance lifting and transfer device, thus achieving greater flexibility in space utilization. One end of the lever 500 along its length is hinged to the plane of the front plate 110 to form a first hinge point, and the middle part of the lever 500 along its length is connected to the end of the slide plate 400 near the front plate 110; thus, the lever 500 can rotate based on the first hinge point. The connection between the middle part of the lever 500 along its length and the slide plate 400 can be varied. For example, the middle part of the lever 500 along its length can be hinged to the end of the slide plate 400 near the front plate 110 to form a second hinge point, and at least one of the first and second hinge points is swayable, so as not to restrict the rotation process of the lever 500; or the middle part of the lever 500 along its length can be connected to the slide plate 400 via a connecting rod. The purpose of the lever 500 is to allow for lever operation of the skateboard 400. The center of the lever 500 along its length is not necessarily the exact center, but only needs to be offset from one end along its length, allowing the lever 500 to rotate. When the lever 500 is pulled outward, the drive unit presses the movable wheel 300 downward, lifting the appliance and facilitating its transfer via the movable wheel 300. When the lever 500 is retracted, the action between the drive unit and the movable wheel 300 is released, causing the movable wheel 300 to retract upward, lowering the appliance and preventing it from moving easily.

[0060] In one embodiment, the front plate 110 and the wing plate 220 are respectively provided with a front through hole and a rear through hole.

[0061] In this embodiment, the front plate 110 and the wing plate 220 are respectively provided with a front through hole and a rear through hole in the width direction; the front and rear feet of the appliance pass through the front and rear through holes respectively to fix the main board 100 to the bottom of the appliance, eliminating the need for position adjustment during the use of the appliance lifting and transfer device. The sliding plate 400 can avoid the front and rear through holes in various ways, such as the above-mentioned staggered setting or the corresponding part of the sliding plate 400 being hollowed out.

[0062] In one embodiment, the front through hole and / or the rear through hole is an oblong hole.

[0063] In this embodiment, the front and rear through holes are respectively for the feet at the front and rear of the appliance to pass through. By designing the front and / or rear through holes as oblong holes, the range of sizes that the appliance lifting and transferring device can accommodate is increased.

[0064] In summary, the appliance lifting and transfer device provided by this utility model, which offers both length adaptation and stable support, allows the appliance to be lifted when the lever 500 operates and the movable wheel 300 is pressed down, with the movable wheel 300 serving as the base for rolling. When the lever 500 operates and the movable wheel 300 is released, the appliance is lowered. The horizontal groove 111 corresponds to the protruding structure at the bottom of the appliance, allowing the remaining parts of the main board 100 to fit snugly against the bottom of the appliance. The sliding extension plate 200 allows the main board 100 and the extension plate 200 to accommodate appliances of various sizes. During the sliding of the extension plate 200 on the main board 100, there is no blind spot in the length adjustment process. The ear support plate 140 on the main board 100 supports the extension plate 200 while also providing a contraction restriction for the perforated seam 221, ultimately reducing the possibility of the extension plate 200 bending or undergoing other deformations.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
