[0033] Reference Figures 1 to 7 In one embodiment of the present invention, a handle fixing structure of a household appliance transport device includes:

[0034] The main structure plate 100 has a sliding limiting groove 110 provided on its lower surface along the length direction;

[0035] A plurality of movable wheel portions 200 are arranged at intervals in the length direction of the sliding limiting groove 110;

[0036] A sliding portion 300 is slidably disposed in the sliding limiting groove 110 , and a plurality of driving portions are disposed on the sliding portion 300 corresponding to the plurality of movable wheel portions 200 ;

[0037] The handle portion 400 has one end in the longitudinal direction hinged to the front end of the main structure plate 100 to form a first hinge point 410, and the middle portion in the longitudinal direction of the handle portion 400 is connected to the front end of the sliding portion 300;

[0038] The anti-vibration rod assembly 500 includes a rod body 510 and a clamp 520. One end of the rod body 510 is connected to the front end of the main structure plate 100, and the other end of the rod body 510 is arranged corresponding to the middle of the handle portion 400 in the inward rotation state.

[0039] Among them, when the handle part 400 rotates outward, the driving part presses the movable wheel part 200 downward, and the other end of the rod body 510 in the length direction is separated from the handle part 400; when the handle part 400 rotates inward, the action of the driving part and the movable wheel part 200 is released and the movable wheel part 200 is retracted, and the other end of the rod body 510 in the length direction is fixed to the middle part of the handle part 400 in the length direction through the clamp 520.

[0040] In the prior art, the loosening of the lever after inward rotation is disadvantageous during the production, warehousing and transfer processes; especially during the use of household appliances (such as washing machines or refrigerators), which themselves generate vibrations, then if the lever is loose, the possibility of the lever generating abnormal vibrations is also greater, thereby generating abnormal noise.

[0041] In the present invention, the handle fixing structure of the household appliance transfer device is fixed in the up and down directions when in use, so a certain direction indication is performed in an up and down manner. The main structure plate 100 serves as the structural foundation, and the sliding limiting groove 110 thereon provides a basis for the subsequent installation of the sliding part 300. The lower surface of the main structure plate 100 is a fully enclosed or partially open frame structure, and a sliding limiting groove 110 is formed. The front and rear ends of the main structure plate 100 can be respectively provided with a front fixing through hole 120 and a rear fixing through hole 130. The front standing feet and the rear standing feet of the household appliance respectively pass through the front fixing through hole 120 and the rear fixing through hole 130 to fix the main structure plate 100 to the bottom of the household appliance.

[0042] The plurality of movable wheel portions 200 are arranged at intervals in the longitudinal direction of the main structural plate 100 . The structural form of the movable wheel portion 200 can be various, depending on whether it can complete the inward rotation and lowering action on the main structural plate 100 .

[0043] The sliding portion 300 is disposed longitudinally within the sliding restriction groove 110 . Multiple driving portions are provided on the sliding portion 300 , corresponding to the multiple movable wheel portions 200 . The driving portions can have various structural forms, such as protrusions or grooves, depending on their ability to actuate the movable wheel portions 200 . This will be described in detail in subsequent embodiments.

[0044] One end of the handle 400 is hinged to the plane of the main structural plate 100 to form a first hinge point 410. The middle portion of the handle 400 is connected to the front end of the sliding portion 300, thereby enabling the handle 400 to rotate based on the first hinge point 410. The connection between the middle portion of the handle 400 and the sliding portion 300 can be various. For example, the middle portion of the handle 400 can be hinged to the front end of the sliding portion 300 to form a second hinge point, with at least one of the first hinge point 410 and the second hinge point being swingable so as not to restrict the rotation of the handle 400. Alternatively, the middle portion of the handle 400 can be connected to the sliding portion 300 via a connecting rod. The purpose of the handle 400 is to enable lever operation of the sliding portion 300 by operating the handle 400. The middle of the handle portion 400 in the length direction is not limited to the exact middle of the length, but is only required to be offset from one end of the handle portion 400 in the length direction so that the handle portion 400 can rotate.

[0045] The anti-vibration rod assembly 500 includes a rod body 510 and a clamp head 520. One end of the rod body 510 is connected to the front end of the main structure plate 100. The other end of the rod body 510 is arranged corresponding to the middle of the handle portion 400 in the inner rotation state.

[0046] When the handle portion 400 rotates outward, the driving portion presses the movable wheel portion 200 downward, the household appliance is lifted up, and the movable wheel portion 200 can serve as a basis for rolling; the other end of the rod body 510 in the length direction is separated from the handle portion 400. At this time, the clamping head 520 can be on the rod body 510 or the handle portion 400, and the anti-vibration rod assembly 500 will not interfere with the operation of the handle portion 400.

[0047] When the handle portion 400 rotates inward, the action of the driving portion and the movable wheel portion 200 is released and the movable wheel portion 200 is retracted, and the home appliance is lowered; the other end of the rod body 510 in the length direction is fixed to the middle part of the handle portion 400 in the length direction through the clamp 520, so that the vibration of the handle portion 400 is limited by the anti-vibration rod assembly 500.

[0048] In summary, when the handle 400 is rotated outward, the rod 510 of the anti-vibration rod assembly 500 separates from the handle 400, and the anti-vibration rod assembly 500 does not interfere with the operation of the handle 400. When the handle 400 is rotated inward, the other end of the rod 510 is fixed to the middle portion of the handle 400 in the longitudinal direction via the clamp 520. As a result, the vibration of the handle 400 is limited by the anti-vibration rod assembly 500, thereby limiting the possibility of the handle 400 becoming loose or generating abnormal noise.

[0049] Reference Figures 1 to 3In one embodiment, the movable wheel portion 200 includes a fixed shaft 210 and a swing frame 220, and a plurality of the fixed shafts 210 are arranged at intervals in the length direction of the sliding limiting groove 110. The fixed shafts 210 are fixed across the width direction of the sliding limiting groove 110. The swing frame 220 is hinged to the fixed shaft 210 and a roller 230 is connected to the free end; the driving portion is a raised platform 310 arranged at the bottom of the sliding portion 300.

[0050] In this embodiment, a movable wheel unit 200 is provided. Multiple fixed shafts 210 within the movable wheel units 200 are spaced apart along the length of the sliding restriction slot 110. The fixed shafts 210 are fixed across the width of the sliding restriction slot 110, forming a stable support. A swing frame 220 is hinged to the fixed shafts 210, with rollers 230 provided at the free ends of the swing frame 220. This allows the movable wheel unit 200 to swing with the fixed shafts 210 as a base. When the movable wheel unit 200 swings out of the sliding restriction slot 110, the appliance is lifted up, with the rollers 230 serving as a base for rolling. When the movable wheel unit 200 rotates inwardly within the sliding restriction slot 110, the appliance is lowered.

[0051] Reference Figure 2 In one embodiment, a limiting seat 320 is provided on the lower surface of the main structure plate 100 , wherein when the handle portion 400 rotates inward, the limiting seat 320 contacts the swing frame 220 and limits the swing frame 220 from swinging.

[0052] In this embodiment, a limiting seat 320 corresponding to the swing frame 220 is provided on the lower surface of the main structure plate 100, and when the handle portion 400 is rotated inward, the limiting seat 320 contacts the swing frame 220 and limits the swing of the swing frame 220. Through the setting of the above limiting seat 320, the swing frame 220 will not become loose in the non-ejected state.

[0053] Reference Figures 4 to 5 In one embodiment, the driving portion is a lifting groove 330 that passes through the thickness direction of the sliding portion 300, and the lifting groove 330 extends upward from the lower part of the sliding portion 300 in the height direction and obliquely toward the front end of the main structure plate 100; the movable wheel portion 200 includes a wheel axle 240 and a wheel body 250 rotatably arranged on the wheel axle 240, and a plurality of vertical grooves 111 are arranged at intervals in the length direction of the sliding limiting groove 110, and the wheel axle 240 passes through the vertical grooves 111 and the lifting groove 330 and is movably arranged in the height direction of the vertical groove 111.

[0054] In this embodiment, the movable wheel portion 200 is confined within the vertical slot 111 and can rise and fall in the height direction of the vertical slot 111. When the movable wheel portion 200 rises, the handle fixing structure of the household appliance transfer device is in a retracted state, and the position of the household appliance cannot be easily transferred. However, when the movable wheel portion 200 descends, the household appliance is lifted up, and the household appliance can now be easily transferred via the movable wheel portion 200. The driving force for the movable wheel portion 200 to rise and fall within the vertical slot 111 comes from the movement of the lifting slot 330. When the sliding portion 300 moves, the position of the lifting slot 330 thereon also moves. The wheel axle 240 is disposed through the lifting slot 330. Due to the inclined nature of the lifting slot 330, the movable wheel portion 200 can move in the vertical direction, which can also be achieved through the movement of the sliding portion 300.

[0055] Reference Figure 7 In one embodiment, the rod body 510 and the main structure plate 100 are an integrally formed structure.

[0056] In this embodiment, the shaping process of the rod body 510 can be achieved by cutting and sheet metal processing, thereby reducing the complexity of processing and assembly. The specific shape of the rod body 510 can also be diverse and will not be affected by the sheet metal processing method.

[0057] In one embodiment, the rod body 510 and the main structure plate 100 are connected by welding, bolts or rivets.

[0058] In this embodiment, the rod body 510 is independently processed into a shape and material, which provides greater freedom. It is connected to the main structure plate 100 by common welding, bolt connection or rivet connection. In other embodiments, the connection method of the rod body 510 can also be a common method in the prior art.

[0059] Reference Figures 1 to 2 In one embodiment, the rod body 510 is in the shape of a straight rod or an "L"-shaped rod.

[0060] In this embodiment, two types of shapes are provided which are easier to process and can conveniently correspond to the middle portion of the handle portion 400 in the inwardly rotated state in the longitudinal direction.

[0061] In one embodiment, the clamp head 520 is made of polymer material.

[0062] In this embodiment, the material of the clamp head 520 is limited to polymer materials, such as conventional plastic or rubber, etc. Then, the clamp head 520 can provide a good elastic fixation while also providing a damping effect to avoid the generation of noise.

[0063] In one embodiment, a front fixing through hole 120 and a rear fixing through hole 130 are respectively provided at the front end and the rear end of the main structure plate 100 .

[0064] In this embodiment, the appliance transfer device can be fixed to the bottom of the appliance during use through the front fixing holes 120 and the rear fixing holes 130 on the main structure plate 100. Specifically, the main structure plate 100 can be fixed to the bottom of the appliance by bolts or fixing feet.

[0065] The utility model also provides a household appliance transporting device, comprising the above-mentioned handle fixing structure.

[0066] In this embodiment, the household appliance transport device has a handle fixing structure. When the handle portion 400 is rotated inward, due to the fixing effect provided by the anti-vibration rod assembly 500, the handle portion 400 is restricted from generating abnormal vibrations during the operation of the household appliance, thereby avoiding the generation of noise.

[0067] In summary, the handle fixing structure and the appliance transport device provided by the present invention enable the rod body 510 of the anti-vibration rod assembly 500 to separate from the handle body 400 when the handle body 400 is rotated outward, and the anti-vibration rod assembly 500 does not interfere with the operation of the handle body 400. When the handle body 400 is rotated inward, the other end of the rod body 510 is fixed to the middle portion of the handle body 400 along its length by the clamp 520. As a result, the vibration of the handle body 400 is limited by the anti-vibration rod assembly 500, thereby limiting the possibility of the handle body 400 becoming loose or generating abnormal noise.

[0068] 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.
