[0035] Reference Figures 1 to 8 In one embodiment of this utility model, a fixed household appliance transfer device includes:
[0036] The support part 100 is in the shape of a straight plate, and the lower surface is bent to form a sliding groove 110 extending along the length direction. The front end and the rear end of the support part 100 are respectively provided with a first fixing hole 120 and a second fixing hole 130.
[0037] Multiple movable wheel sections 200, each movable wheel section 200 including a hinge shaft 210 and a swing frame 220, the multiple hinge shafts 210 are spaced apart in the length direction of the slide groove 110, the hinge shafts 210 are fixed across the width direction of the slide groove 110, and the swing frame 220 is hinged to the hinge shaft 210 and has a roller 230 connected to its free end;
[0038] The sliding part 300 is slidably disposed in the slide groove 110 along the length direction. The lower surface of the sliding part 300 is provided with a plurality of protrusions 310 corresponding to the plurality of swing frames 220. The first fixing hole 120 and the second fixing hole 130 are disposed to avoid the sliding part 300.
[0039] The lever 400 has one end hinged to the front end plane of the support 100 to form a first hinge point 410 in the length direction, and the middle part of the lever 400 in the length direction is hinged to the front end of the sliding part 300 to form a second hinge point 420. At least one of the first hinge point 410 and the second hinge point 420 is oscillable.
[0040] When the lever 400 is pulled outward, the protruding plate 310 presses the movable wheel 200 downward; when the lever 400 is retracted inward, the interaction between the protruding plate 310 and the movable wheel 200 is released, and the movable wheel 200 retracts upward.
[0041] In the existing technology, there is a pressing need to rationalize the design of the transfer device, simplify its structure, and achieve a superior performance while keeping the lifting device permanently fixed to the bottom of the appliance.
[0042] In this utility model, the fixed appliance transfer device is fixed in the up and down directions during use, thus providing directional indication in an up-and-down manner. The lower surface of the straight plate-shaped support part 100 is bent to form a sliding groove 110 extending along its length. The front and rear ends of the support part 100 are respectively provided with a first fixing hole 120 and a second fixing hole 130. The support part 100 is integrally formed. The cross-section of the support part 100 is a fully or partially open frame structure, forming the sliding groove 110. The support part 100 provides structural connection while also providing a foundation for the subsequent installation of the sliding part 300. The front and rear feet of the appliance pass through the first fixing holes 120 and the second fixing holes 130, respectively, to fix the support part 100 to the bottom of the appliance.
[0043] The movable wheel section 200 includes a hinge shaft 210 and a swing frame 220. Multiple hinge shafts 210 are spaced apart along the length of the slide groove 110, and each hinge shaft 210 is fixed across the width of the slide groove 110. The swing frame 220 is hinged to the hinge shaft 210, and its free end is connected to a roller 230. The swing frame 220 swings based on the hinge shaft 210.
[0044] The sliding part 300 is slidably disposed in the slide groove 110 along its length. Multiple protrusions 310 are welded onto the sliding part 300 corresponding to the multiple swing frames 220 (they can also be stamped). The first fixing hole 120 and the second fixing hole 130 are disposed to avoid the sliding part 300. The welding form of the protrusions 310 provides a better choice for both shape and structural strength. Thus, the movable wheel part 200 can swing around the hinge shaft 210. When the movable wheel part 200 swings out of the support part 100, the appliance is lifted, and the roller 230 serves as the basis for rolling; when the movable wheel part 200 retracts into the support part 100, the appliance is lowered.
[0045] One end of the lever 400 along its length is hinged to the front end plane of the support 100 to form a first hinge point 410. The middle part of the lever 400 along its length is connected to the front end of the sliding part 300. The middle part of the lever 400 along its length is hinged to the front end of the sliding part 300 to form a second hinge point 420. At least one of the first hinge point 410 and the second hinge point 420 is oscillating, so as not to restrict the rotation process of the lever 400. The purpose of the lever 400 is to enable lever operation of the sliding part 300 by operating the lever 400. The middle part along the length of the lever 400 is not limited to the exact center of its length, but only requires to be offset from one end along the length of the lever 400, so that the lever 400 can rotate.
[0046] When the lever 400 is pulled outward, the protruding platform 310 presses the movable wheel 200 downward, at which point the appliance can be lifted up, and through the action of the movable wheel 200, the appliance can be easily moved; when the lever 400 is retracted inward, the action between the protruding platform 310 and the movable wheel 200 is released, and the movable wheel 200 retracts upward, at which point the appliance is put down and is not easily moved.
[0047] In summary, the lower surface of the straight plate-shaped support 100 is bent to form a groove 110 extending along the length direction, which is compact and provides a positional basis for the subsequent installation and operation of the sliding part 300; the first fixing hole 120 and the second fixing hole 130 serve as the base for connecting the support 100 to the appliance; when the lever 400 is operated, it can control the outward and inward turning of the movable wheel part 200; the protruding form of the platform 310 can efficiently drive the swing of the swing frame 220.
[0048] Reference Figures 4 to 6 In one embodiment, the fixed appliance transfer device further includes:
[0049] The front pad 500 is detachably disposed on the upper surface corresponding to the front end of the support portion 100;
[0050] The rear pad 600 is detachably disposed on the upper surface corresponding to the rear end of the support portion 100.
[0051] In this embodiment, considering the complexity of the appliance's bottom shape, the shape of the support portion 100 may not necessarily fit well with the appliance's bottom. For example, due to the diversity of appliance bottom shapes, reinforcing ribs may be provided at the front and / or rear of the appliance's bottom surface. Through the supporting action of the front pad 500 and the rear pad 600, the support portion 100 can be supported on the bottom of the appliance, avoiding the reinforcing ribs. The introduction of the front pad 500 and the rear pad 600 supports the entire support portion 100, thereby improving the compatibility with various appliance models. The connection between the front pad 500 and the support portion 100 can be varied, such as snap-fit, fastening, or screw connection; in some embodiments, the front pad 500 can also support the support portion 100 without forming a connection. The connection between the rear pad 600 and the support portion 100 can be varied, such as snap-fit, fastening, or screw connection; in some embodiments, the rear pad 600 can also support the support portion 100 without forming a connection. The materials of the front pad 500 and the rear pad 600 are preferably polymers, which have suitable structural strength without causing damage to the relevant structures.
[0052] Reference Figures 4 to 5 In one embodiment, the fixed appliance transfer device further includes a rib pad 700, which is detachably fixed between the upper surface of the middle part of the support 100 in the length direction and the bottom of the external appliance.
[0053] During the use of a fixed appliance transfer device, the bottom of the appliance (such as a refrigerator or washing machine) is often uneven, which can lead to instability in the contact between the support 100 and the bottom of the appliance, potentially causing structural deformation of the support 100. In this embodiment, at least one rib pad 700 is introduced. The rib pad 700 can be installed with the support 100 using screws or other methods (such as snap-fit connections), thereby maintaining the structural stability of the support 100. The rib pad 700 is preferably made of a polymer, which facilitates the installation process while providing structural support.
[0054] Reference Figures 1 to 3 In one embodiment, a support seat 140 is provided on the lower surface of the support portion 100, wherein when the lever 400 is retracted, the support seat 140 abuts against the swing frame 220 and restricts the swing of the swing frame 220.
[0055] In this embodiment, a support seat 140 corresponding to the swing frame 220 is provided on the lower surface of the support portion 100. When the lever 400 retracts, the support seat 140 abuts against the swing frame 220, thus restricting the swing of the swing frame 220. Through the provision of the support seat 140, the swing frame 220 will not loosen when not in the ejected state. The support seat 140 can be connected by welding, bonding, or snap-fitting, etc.
[0056] In one embodiment, the abutment 140 is welded to the support portion 100.
[0057] In this embodiment, the welding of the support seat 140 provides a better choice in terms of both shape and structural strength.
[0058] Reference Figures 1 to 3 In one embodiment, the first fixing hole 120 and / or the second fixing hole 130 are oblong holes along the length direction of the support portion 100.
[0059] In this embodiment, the first fixing hole 120 and the second fixing hole 130 are respectively provided for the feet at the front and rear of the appliance to pass through. By configuring the first fixing hole 120 and / or the second fixing hole 130 as oblong holes, the range of sizes that the fixed appliance transfer device can accommodate is increased.
[0060] Reference Figures 1 to 3 In one embodiment, the support portion 100 is provided with side auxiliary fixing holes 131 arranged along the length direction on both sides of the second fixing hole 130 in the width direction.
[0061] In existing technology, besides traditional mounting feet, hydraulic mounting feet 010 also exist at the rear of home appliances. Compared to the relatively simple fixing method of traditional mounting feet (such as through a single threaded hole), hydraulic mounting feet 010 require multiple fixing holes (such as four). Hydraulic mounting feet 010 are fixed via side auxiliary fixing holes 131. For example, hydraulic mounting feet 010 are fixed using four screws, which pass through the hydraulic mounting feet 010 and the side auxiliary fixing holes 131 before connecting to the home appliance.
[0062] Reference Figures 1 to 3 In one embodiment, the side auxiliary fixing hole portion 131 includes a long waist-shaped hole or includes a plurality of sub-long waist-shaped holes spaced apart in the length direction.
[0063] In this embodiment, the side auxiliary fixing hole 131 can be a single elongated slotted hole, thus maximizing its adaptability to various size conditions. Alternatively, the side auxiliary fixing hole 131 may include sub-elongated slotted holes spaced apart along the length direction, ensuring structural strength of the support 100 while guaranteeing adaptability to various size conditions.
[0064] Reference Figures 4 to 5 In one embodiment, the rear pad 600 is provided with a third fixing hole 610 corresponding to the second fixing hole 130 and a fourth fixing hole group 620 corresponding to the side auxiliary fixing hole portion 131.
[0065] In this embodiment, the rear pad 600 is fixed to the support 100 via the third fixing hole 610. A screw passes through the third fixing hole 610 to connect the rear pad 600 to the support 100 and the bottom of the appliance. The external hydraulic foot 010 can be fixed to the rear pad 600 via the fourth fixing hole group 620 (including multiple fourth fixing holes). The fixing screw of the hydraulic foot 010 passes through the side auxiliary fixing hole 131 and connects to the fourth fixing hole group 620 on the fourth fixing hole group 620.
[0066] Reference Figures 6 to 7 In one embodiment, the rear pad 600 is provided with a third fixing hole 610 and a fourth fixing hole group 620 corresponding to the second fixing hole 130, and the third fixing hole 610 and the fourth fixing hole group 620 are arranged side by side.
[0067] In this embodiment, the rear pad 600 is fixed to the support 100 via the third fixing hole 610. A screw structure passes through the third fixing hole 610 to connect the rear pad 600 to the support 100 and the bottom of the appliance. The external hydraulic foot 010 can be fixed via the fourth fixing hole group 620 (including multiple fourth fixing holes). The third fixing hole 610 and the fourth fixing hole group 620 are arranged side by side, so their use will not interfere with each other. The third fixing hole 610 can complete the fixing of a normal foot, and the fourth fixing hole group 620 completes the fixing of the hydraulic foot 010, thus enabling diverse support actions.
[0068] In summary, the fixed appliance transfer device provided by this utility model has a straight plate-shaped support part 100 with a curved lower surface forming a groove 110 extending along the length direction. The structure is compact and provides a positional basis for the subsequent installation and operation of the sliding part 300. The first fixing hole 120 and the second fixing hole 130 serve as the support part 100 connected to the base of the appliance. When the lever 400 is operated, it can control the outward and inward rotation of the movable wheel part 200. The protruding form 310 can efficiently drive the swing of the swing frame 220.
