[0002] In a warehouse environment or a household use environment, there are two specific methods for moving heavy household appliances (such as washing machines or refrigerators): using a transfer forklift and manual lifting. There is also a simple lifting device adapted to the household appliance for transfer operation between the two methods. Currently, the lifting device is generally non-fixed. During use, the lifting device is inserted under the household appliance, and then a relevant lever is used to lift the household appliance, and finally the transfer process is completed.
[0003] How to achieve a transfer device with a simple structure and smooth use is relatively important. Only with a simple structure can the processing be convenient and the structural stability be achieved, and only with smooth use can the process of lifting and lowering the household appliance be made stable. Most transfer devices achieve the jacking and lowering actions through a sliding member, so the key to smooth operation lies in the work of the sliding member. Summary of the Utility Model

[0012] Further, a groove is formed on one side of the swing plate corresponding to the lower convex hull to match the lower convex hull.
[0013] Further, a front hollow position and a rear hollow position are respectively arranged at the front end and the rear end of the support member.
[0014] Further, both the front hollow position and the rear hollow position extend inward from the circumferential edge of the support member to form a bayonet-shaped structure.
[0015] Further, the rear hollow position extends from the rear end in the length direction of the support member, and the front hollow position extends from the side surface of the support member.
[0016] Further, both the support member and the sliding plate are integrally formed structures.
[0017] Further, the surface of the lower convex hull facing the turning wheel part is an inclined slope.
[0018] Further, a rubber layer is arranged on the outer peripheral wall of the roller.

[0033] Refer to Figures 1 to 7 , in an embodiment of the present utility model, a household appliance lifting and handling device includes:
[0034] The plate-shaped support member 100 has a receiving groove 110 that is open downward along the length direction on the lower surface;
[0035] Two flipping wheel parts 200, the flipping wheel part 200 includes a fixed shaft 210 and a swinging plate 220. The two fixed shafts 210 are fixed at both ends in the length direction of the receiving groove 110 and span its width direction. The swinging plate 220 is hinged to the fixed shaft 210 and a roller 230 is connected to the free end;
[0036] A sliding plate 300 is slidably arranged in the receiving groove 110 along the length direction. A lower convex protrusion 310 corresponding to the flipping wheel part 200 is integrally formed at the bottom of the sliding plate 300;
[0037] A lever member 400 has one end in the length direction hinged to the front end plane of the support member 100;
[0038] A connecting rod 500 has two ends in the length direction respectively hinged to the middle of the length direction of the lever member 400 and the front end of the sliding plate 300;
[0039] Wherein, when the lever member 400 is pulled outwards, the lever member 400 moves towards the front end and the lower convex protrusion 310 presses the flipping wheel part 200 downwards; when the lever member 400 is retracted inwards, the lever member 400 moves towards the rear end, and the lower convex protrusion 310 releases the flipping wheel part 200 and retracts the flipping wheel part 200 upwards.
[0040] In the prior art, only with a simple structure can the processing be convenient and the structural stability be achieved, and only with smooth use can the process of lifting and lowering household appliances be stabilized; most transfer devices achieve the lifting and lowering actions through a sliding member, so the key to specific smooth operation lies in the work of the sliding member.
[0041] In the present utility model, when the household appliance lifting and carrying device is in use, the up and down directions are fixed, so certain direction indications are made in the up and down manner. A receiving groove 110 with a downward open cross-section is provided on the lower surface in the length direction of the support member 100. The receiving groove 110 can be processed by means such as stamping and bending.
[0042] Two turning wheel parts 200 are arranged at both ends of the support member 100 in the length direction. The turning wheel part 200 includes a fixed shaft 210 and a swing plate 220. The fixed shaft 210 is fixed across its width direction, thereby providing a basis for the installation of the swing plate 220. The swing plate 220 is hinged to the fixed shaft 210 and a roller 230 is connected to the free end. Thus, the swing plate 220 can swing based on the fixed shaft 210. The plate-like structure of the swing plate 220 facilitates the interaction with the subsequent lower convex portion 310. For example, the shape of the lower convex portion 310 can be set to be smaller, and still can stably interact with the swing plate 220 at this time. The small size of the lower convex portion 310 is beneficial for processing and for enhancing the structural strength at this position.
[0043] The sliding plate 300 is arranged to slide in the accommodation groove 110 in the length direction. An integrally formed lower convex portion 310 is provided on the sliding plate 300 corresponding to the multiple turning wheel parts 200. The lower convex portion 310 can be conveniently processed by stamping. Preferably, the lower convex portion 310 has an arc-shaped top, so that the lower convex portion 310 can stably drive the swing plate 220.
[0044] One end of the lever 400 in the length direction is hinged to the front end plane of the support member 100 to form a fixed point, so that the lever 400 can rotate based on the support member 100. A connection is achieved between the middle part of the lever 400 in the length direction and the sliding plate 300 through a connecting rod 500. The connection manner between the connecting rod 500 and the sliding plate 300 and the lever 400 is preferably achieved by riveting for hinging. The middle part of the lever 400 in the length direction is not limited to being strictly in the middle, as long as it is offset from the fixed point. At this time, the lever 400 can complete rotation based on the fixed point. The linkage between the lever 400 and the sliding plate 300 is achieved through the connecting rod 500. At this time, the power generated by the rotation of the connecting rod 500 can be more smoothly transmitted to the sliding plate 300, and the sliding plate 300 then slides. Further, the lower convex portion 310 on the sliding plate 300 interacts with the turning wheel part 200.
[0045] When the lever 400 is pulled outwards, the lever 400 moves forward and the lower convex portion 310 presses the turning wheel part 200 downwards. At this time, the transfer process of the household appliance can be completed. When the lever 400 is retracted inwards, the lever 400 moves backwards and the lower convex portion 310 releases the turning wheel part 200 and retracts the turning wheel part 200 upwards. At this time, the household appliance is put down.
[0046] In summary, the swing plate 220 can swing based on the fixed shaft 210. The plate-like structure of the swing plate 220 facilitates the interaction with the subsequent lower convex hull 310. The lower convex hull 310 can be conveniently processed by stamping. The linkage between the actuating member 400 and the sliding plate 300 is realized through the connecting rod 500. At this time, the power generated by the rotation of the connecting rod 500 can be transmitted to the sliding plate 300 more smoothly, and the sliding plate 300 then slides. Furthermore, the lower convex hull 310 on the sliding plate 300 interacts with the turning wheel portion 200.
[0047] In one embodiment, a groove is formed corresponding to the lower convex hull 310 on the surface of the swing plate 220 that matches the lower convex hull 310.
[0048] In this embodiment, the shape of the swing plate 220 is restricted, so that when the lower convex hull 310 is combined with the swing plate 220, the two are not easily separated under the pressure from above; while the movement of the sliding plate 300 can cause the lower convex hull 310 to separate from the swing plate 220. The formation of the groove can be synchronized during the stamping process of the lower convex hull 310.
[0049] Refer to Figure 1 , in one embodiment, a front hollow position 120 and a rear hollow position 130 are respectively arranged at the front end and the rear end of the support member 100.
[0050] In this embodiment, during the use of the home appliance transfer device, it can be fixed to the bottom of the home appliance through the front hollow position 120 and the rear hollow position 130 on the support member 100. Specifically, the support member 100 can be fixed to the bottom of the home appliance through structures such as bolts or fixed feet.
[0051] Refer to Figure 1 , in one embodiment, both the front hollow position 120 and the rear hollow position 130 extend inward from the circumferential edge of the support member 100 to form a bayonet-like structure.
[0052] In this embodiment, the structural shapes of the front hollow position 120 and the rear hollow position 130 are restricted, thereby improving the convenience of installing the support member 100 at the bottom of the home appliance. For example, if the positions of the front hollow position 120 and the rear hollow position 130 both correspond to the fixed standing feet, then during the installation and disassembly process, through the above bayonet-like structure, only the fixed standing feet need to be loosened (without completely removing them) to complete the installation or disassembly of the support member 100 on the home appliance, reducing the operation difficulty.
[0053] Refer to Figure 1 , in one embodiment, the rear hollow position 130 starts to extend from the rear end in the length direction of the support member 100, and the front hollow position 120 starts to extend from the side of the support member 100.
[0054] In this embodiment, the rear hollow position 130 is defined by the starting position of the extension of the support member 100. The support member 100 can be inserted from the front end of the household appliance (convenient for alignment). Then, the rear hollow position 130 is connected to the rear fixed foot, and then the rear hollow position 130 is connected to the front fixed foot in a side-swinging manner. To disassemble the support member 100, refer to the reverse process described above.
[0055] In one embodiment, both the support member 100 and the sliding plate 300 are integrally formed structures.
[0056] In this embodiment, the support member 100 and the sliding plate 300 are formed by stamping and bending, thereby reducing the processing cost and improving the processing efficiency.
[0057] Refer to Figure 1 In one embodiment, the surface of the lower convex portion 310 facing the flipping wheel portion 200 is an inclined slope.
[0058] In this embodiment, through the external shape setting of the lower convex portion 310, the process of driving the flipping wheel portion 200 is made smoother and more stable.
[0059] In one embodiment, a rubber layer is provided on the outer peripheral wall of the roller 230.
[0060] In this embodiment, the material of the outer wall of the roller 230 is restricted, so that the friction between the roller 230 and the external base surface is increased, making it easier to roll. At the same time, the probability of damaging the lower convex portion 310 is also reduced.
[0061] Refer to Figure 4 and 6 In one embodiment, a guiding groove 320 extending along the length direction of the support member 100 is provided in the thickness direction of the sliding plate 300, and the fixed shaft 210 is correspondingly provided with respect to the guiding groove 320.
[0062] In this embodiment, through the cooperation formed between the fixed shaft 210 and the guiding groove 320 provided on the sliding plate 300, while making the sliding process of the sliding plate 300 more stable, a good fixation can be formed between the sliding plate 300 and the support member 100 in the thickness direction, reducing the possibility of structural abnormalities.
[0063] Refer to Figure 4 In one embodiment, rib protrusions 330 protruding upward or downward are formed by stamping in the length direction of the sliding plate 300.
[0064] In this embodiment, rib protrusions 330 are machined in the longitudinal direction of the plate-shaped support member 100 by stamping, and the above machining process can be synchronously realized during the machining process of the entire support member 100. Without increasing the machining difficulty, the structural strength of the support member 100 in the longitudinal direction is improved.
[0065] In summary, for the household appliance lifting and handling device provided by the present utility model, the swing plate 220 can swing based on the fixed shaft 210, and the plate-shaped structure of the swing plate 220 facilitates the formation of an interaction with the subsequent lower convex portion 310; the lower convex portion 310 can be conveniently machined by stamping; the linkage between the actuating member 400 and the sliding plate 300 is realized through the connecting rod 500. At this time, the power generated by the rotation of the connecting rod 500 can be more smoothly transmitted to the sliding plate 300, and the sliding plate 300 then slides. Furthermore, the lower convex portion 310 on the sliding plate 300 interacts with the turning wheel portion 200.
[0066] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
