Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a mobile rack and a household appliance. Background Art

[0002] For household appliances such as washing machines, freezers, and refrigerators, due to their large size and heavy weight, they are inconvenient to move or are time-consuming and laborious to move. There are two ways to move heavier household appliances (such as washing machines or refrigerators): using a transfer forklift and manual handling. However, in home use scenarios, a transfer forklift is not a reasonable choice, and manual handling is also difficult. In the prior art, there is a solution of installing a mobile bracket at the bottom of the household appliance. This type of mobile bracket has a handle and rollers. The household appliance can be lifted by turning the handle, and then the household appliance can be moved by dragging this type of mobile bracket.

[0003] The Chinese utility model patent with publication number CN218114949U discloses a washing machine dragging and lifting base, in which a sliding member is slidably arranged in a sliding groove, a supporting member is penetrated by two roller assemblies in the width direction, a first lifting groove and a second lifting groove corresponding to two fixed axes and penetrating the width direction of the supporting member are arranged in the length direction of the sliding member, one end of the pulling member in the length direction is hinged to the front end of the supporting member in the length direction, and the middle part of the pulling member in the length direction forms a movable fit with the front end of the sliding member in the length direction.

[0004] For another example, a Chinese utility model patent with publication number CN218001033U discloses a seesaw-type mobile bracket, comprising an outer groove plate for connecting household appliances, an inner groove plate located inside the outer groove plate and slidable relative to the outer groove plate, a plurality of lifting components evenly spaced on the outer groove plate and the inner groove plate and used for lifting and moving the household appliances, and a wrench component for driving the inner groove plate to slide.

[0005] In the above-mentioned prior art, when the roller needs to be lifted to the required height, the lifting mechanism in the prior art requires the sliding member or the inner groove plate to have a long lateral displacement. At this time, the connection point between the wrench and the sliding member in the wrench assembly needs to move a long distance in the width direction of the outer groove plate. Based on the considerations of economy and convenience, the overall width of the outer groove plate should not be too large. Therefore, the mobile bracket in the prior art often chooses to increase the width of the end of the outer groove plate. However, when the width of the end of the outer groove plate increases, the product still consumes more raw materials. In addition, this type of mobile bracket also has defects in transportation and storage. Utility Model Content

[0075] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0076] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0077] In one embodiment, the utility model provides a mobile frame, comprising an outer groove plate 101, an inner moving member 104, a rotating handle 201, and a lifting mechanism. The inner moving member 104 is arranged in the outer groove plate 101 and can slide relative to the outer groove plate 101, that is, when the outer groove plate 101 is fixedly connected to the object to be moved, the inner moving member 104 can slide in the outer groove plate 101.

[0078] In this embodiment, the rotating handle 201 is rotatably mounted on one end of the outer groove plate 101 and is transmission-connected to the inner moving member 104 . The transmission connection here means that when the rotating handle 201 is rotated, the inner moving member 104 is driven to slide in the outer groove plate 101 .

[0079] Specifically, the rotating handle 201 has a first connection point 202 and a second connection point 203, wherein the first connection point 202 is hinged to the outer groove plate 101, and the second connection point 203 is movably connected to the inner moving member 104. The distance between the first connection point 202 and the second connection point 203 determines the sliding stroke of the inner moving member 104.

[0080] In this embodiment, the first connection point 202 may be a rotating shaft, that is, the rotating handle 201 and the outer groove plate 101 are hinged together through the rotating shaft, so that the rotating handle 201 can rotate relative to the outer groove plate 101.

[0081] In this embodiment, the lifting mechanism includes a swinging member and a resisting member that cooperate with each other, wherein one end of the swinging member is hingedly mounted, and the other end thereof is mounted with a roller 302. The lifting mechanism is connected to the outer groove plate 101 and the inner moving member 104 respectively, that is, the swinging member of the lifting mechanism is connected to the outer groove plate 101, and the resisting member is connected to the inner moving member 104 correspondingly; or the swinging member of the lifting mechanism is connected to the inner moving member 104, and the resisting member is connected to the outer groove plate 101 correspondingly.

[0082] When the rotating handle 201 is rotated, the inner moving member 104 slides, which drives the abutting member and the swinging member to move relative to each other, so that the end of the swinging member provided with the roller 302 is tilted, so that the roller 302 contacts the ground (or other bearing surface), thereby raising the outer groove plate 101. On the contrary, when the inner moving member 104 slides in the opposite direction, the end of the swinging member provided with the roller 302 will fall, thereby lowering the outer groove plate 101.

[0083] In this embodiment, the width of the outer groove plate 101 is substantially equal at all locations, that is, the orthographic projection of the outer groove plate 101 is a rectangle, which is similar to a straight line. It should be noted that there may be a depression at the edge of the outer groove plate 101, as long as there is no obvious protrusion at the end of the outer groove plate 101, in which case it should still be considered that the width of the outer groove plate 101 is substantially equal at all locations.

[0084] Both ends of the outer groove plate 101 are provided with a bayonet 103. When the mobile frame needs to be connected to the object to be moved, for example, when the outer groove plate 101 and the object to be moved are connected together by bolts and nuts, the bayonet 103 is used to allow the bolts to pass through. It should be noted that after the missing part of the bayonet 103 is supplemented, the width of each part of the outer groove plate 101 is still roughly equal. In addition, the shape of the bayonet 103 is not limited to the shape shown in the figure, and the bayonet 103 can also be a through hole, a U-shaped groove, etc.

[0085] In order to ensure that there is no obvious protrusion at the end of the outer groove plate 101, so that the width of each part of the outer groove plate 101 is roughly equal, in this embodiment, the first connection point 202 is within the width range of the outer groove plate 101, and when the rotating handle 201 is rotated, the movement trajectory of the second connection point 203 is also within the width range of the outer groove plate 101. Since the lifting mechanism of the utility model adopts a matching swinging member and a resisting member, wherein one end of the swinging member is installed in a hinged manner, the swinging member is rotated by driving the resisting member and the swinging member to move relative to each other, and the elevation angle of the swinging member can be controlled to achieve that the roller still has a high lifting height when the inner moving member 104 has a short stroke, so the movement trajectory of the second connection point 203 is within the width range of the outer groove plate 101. At this time, the moving distance of the rotating handle and the inner moving member connection point in the width direction of the outer groove plate 101 in the utility model is relatively short. At the same time, the utility model gathers the bayonet 103 within the width range of the outer groove plate 101, so that the width of the outer groove plate 101 is roughly equal at various places, and there is no protrusion at its end, that is, the outer groove plate 101 is in a straight line, so that raw materials can be saved during the production of the mobile frame, and the straight-line mobile frame is also convenient for storage and transportation.

[0086] like Fig.13 As shown, in order to avoid that the force decomposed into the connecting rod 204 is small, resulting in more effort to drive the inner groove plate, the swing angle α of the connecting rod 204 must be guaranteed not to be too large. At this time, since the lifting mechanism roller 302 in the prior art requires the inner groove plate to slide a longer stroke when it is lifted to a higher height, the distance between the first connection point 202 and the second connection point 203 is large, which will inevitably cause the position of the first connection point 202 to be farther from the swing range of the connecting rod 204 (the dotted area in the figure), resulting in the need for a protrusion at the end of the outer groove plate 101 for the installation of the first connection point 202. At this time, this type of moving frame is not in a straight line.

[0087] In the present utility model, Fig.14As shown, in order to avoid the force decomposed into the connecting rod 204 is less, causing the driving interior moving member 104 to consume more energy, so the swing angle α of the connecting rod 204 in the utility model needs to be guaranteed not to be too large, at this moment, because the lifting mechanism roller 302 of the utility model does not need the interior moving member 104 to slide a long stroke when being lifted to a higher height, the spacing between the first connecting point 202 and the second connecting point 203 is less, and this spacing is less than the width L3 of the outer groove plate 101. So the position of the first connecting point 202 is closer to the swing range (dotted line area among the figures) of the connecting rod 204, then the outer groove plate 101 end does not need to be provided with the projection for the first connecting point 202 to be installed, at this moment, the outer groove plate 101 of the utility model is in a straight line, so that the mobile frame can save raw materials when producing, and the straight line mobile frame is also convenient for storage and transportation simultaneously.

[0088] In one embodiment, if Figure 1 As shown, the length of the bayonet 103 is L1, and the width of the outer groove plate 101 is L3, wherein L1≤50%L3. At the same time, in the width direction of the outer groove plate 101, a gap is provided between the second connection point 203 and the bayonet 103, and the gap length is L2. The value of L2 should meet the following requirements: when a fastener is installed in the bayonet 103, this gap should ensure that there is no interference between the second connection point 203 and the fastener.

[0089] In one embodiment, the rotating handle 201 has a force-applying portion. When the rotating handle 201 has a gripping portion, the force-applying portion is located at the gripping portion. Figure 1-2 As shown, the force-applying portion and the second connection point 203 are located on the same side of the first connection point 202. At this time, when the rotating handle 201 rotates from a perpendicular state to the outer groove plate 101 to a parallel state to the outer groove plate 101, the inner moving member 104 is pulled. Figure 3-4 As shown, the force applying portion and the second connection point 203 are respectively located on both sides of the first connection point 202. At this time, when the rotating handle 201 rotates from a perpendicular state to the outer groove plate 101 to a parallel state to the outer groove plate 101, the inner moving member 104 is pushed.

[0090] In one embodiment, the rotating handle 201 is connected to the inner moving member 104 via a connecting rod 204, and specifically, the inner moving member 104 has a third connecting point 205. One end of the connecting rod 204 is hinged to the second connecting point 203, and the other end thereof is hinged to the third connecting point 205. It should be noted that the first connecting point 202, the second connecting point 203, and the third connecting point 205 can all be rotating shafts.

[0091] In another embodiment, the rotating handle 201 is connected to the inner moving member 104 via a connecting portion 206. One end of the connecting portion 206 is fixedly connected to the inner moving member 104, and the other end thereof is provided with a guide groove 207 that matches the second connecting point 203. In this case, both the first connecting point 202 and the second connecting point 203 can be rotating shafts.

[0092] In one embodiment, one end of the swing member is hinged to the outer groove plate 101, and the abutment member is provided on the inner moving member 104. When the rotating handle 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101, the inner moving member 104 slides toward one end of the outer groove plate 101, driving the abutment member to move relative to the swing member, and one end of the swing member provided with the roller 302 tilts up. When the rotating handle 201 rotates from a state parallel to the outer groove plate 101 to a state perpendicular to the outer groove plate 101, the inner moving member 104 slides toward the other end of the outer groove plate 101, and one end of the swing member provided with the roller 302 falls down.

[0093] As an optional implementation scheme, Figure 6-7 Shown, the abutment member is a ramp block 301 located on the interior moving member 104, and in the present embodiment, the interior moving member 104 is a groove plate equally, and the shape of the interior moving member 104 is similar to the outer groove plate 101, and the interior moving member 104 both sides are provided with the third folding edge 105. In the present embodiment, the swing member is a swing plate 304, and the swing plate 304 is hinged with the outer groove plate 101 by the first shaft 303, and at this moment, the third folding edge 105 is provided with the 3rd avoidance groove 305 extending along the length direction of the outer groove plate 101, and after the first shaft 303 two ends pass the 3rd avoidance groove 305, they are hinged with the outer groove plate 101. The 3rd avoidance groove 305 also plays a guiding and limiting role, and the interior moving member 104 can only slide along the length direction of the outer groove plate 101. When the ramp block 301 and the swing plate 304 relative motion occur, the swing plate 304 is provided with the roller 302 one end and lifts or falls.

[0094] Figure 6-7 The figure shows the arrangement direction of the ramp block 301 and the swing plate 304 when the rotating handle 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101 and the inner moving member 104 is pulled. It should be noted that when the rotating handle 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101 and the inner moving member 104 is pushed, the arrangement direction of the ramp block 301 and the swing plate 304 should be the same as Figure 6-7 The opposite is true (not shown in the figure).

[0095] As an optional embodiment (not shown in the figure), the swinging member is a swinging plate 304, and a slope surface is provided on the side of the swinging plate 304 close to the abutting member, and the slope surface cooperates with the abutting member. In this case, the abutting member can be a crossbar or a wedge block that cooperates with the slope surface. When the abutting member and the swinging plate 304 move relative to each other, one end of the swinging plate 304 provided with the roller 302 tilts up or down.

[0096] As an optional implementation scheme, Figure 8-9As shown, the swing member is a first folding plate 401, and the abutting member is a second folding plate 405. Specifically, one end of the first folding plate 401 is hinged with the outer groove plate 101 through the third shaft 402. In the present embodiment, the interior moving member 104 is a groove plate, that is, the interior moving member 104 is similar in shape to the outer groove plate 101, and at this moment, the interior moving member 104 is provided with the third folding edge 105 on both sides, and at this moment, the third folding edge 105 is provided with the first avoidance groove 403 along the length direction of the outer groove plate 101, and the end of the third shaft 402 passes through the first avoidance groove 403 and is hinged with the outer groove plate 101. The first avoidance groove 403 plays a guiding and limiting role, that is, the interior moving member 104 can only slide along the length direction of the outer groove plate 101 in the restriction.

[0097] In the present embodiment, one end of the second folding plate 405 is hinged to the inner moving member 104 through the fourth shaft 406, and the other end thereof is coaxially hinged to the second shaft 404 with the other end of the first folding plate 401. Specifically, the first folding edge 102 of the outer groove plate 101 is provided with a second avoidance groove 407 extending along the length direction of the first folding plate 401. The two ends of the second shaft 404 are hinged to the third folding edge 105 provided on the inner moving member 104, and the two ends thereof also pass through the second avoidance groove 407. The second avoidance groove 407 can play a guiding and limiting role, that is, it limits the inner moving member 104 to slide only along the length direction of the outer groove plate 101.

[0098] In this embodiment, the roller 302 is disposed on the first folding plate 401 or the second folding plate 405 or the second shaft 404. When the first folding plate and the second folding plate move relative to each other, the roller 302 tilts up or down.

[0099] In one embodiment, one end of the swinging member is hinged to the inner moving member 104, and the abutting member is provided on the outer groove plate 101. When the rotating handle 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101, the inner moving member 104 slides toward one end of the outer groove plate 101, driving the swinging member to move relative to the abutting member, and the abutting member abuts the swinging member to rotate, and one end of the swinging member provided with the roller 302 is tilted. When the rotating handle 201 rotates from a state parallel to the outer groove plate 101 to a state perpendicular to the outer groove plate 101, the inner moving member 104 slides toward the other end of the outer groove plate 101, and one end of the swinging member provided with the roller 302 falls.

When the rotating handle 201 is rotated, the interior moving member 104 slides, and the driving ramp block 301 moves relative to the swing plate 304, so that the swing plate 304 is provided with one end of the roller 302 to lift or fall, thereby the outer groove plate 101 is raised or lowered.

[0107] In one embodiment, the cross-sectional shape of the outer groove plate 101 is U-shaped, thereby forming a groove space with a certain height, length and width, and the groove space can accommodate the installation of the base 201. Specifically, the outer groove plate 101 is provided with a first folded edge 102 on both sides along its length direction. The height, length and width of the outer groove plate 101 can be determined according to the size and weight of the object to be lifted. Generally, the length and width of the outer groove plate 101 should meet the requirement that the outer groove plate 101 can be completely placed on the bottom surface of the object to be lifted without being exposed. At the same time, the height of the outer groove plate 101 should also meet the requirement that the outer groove plate 101 can be installed on the bottom surface of the object to be lifted.

[0108] It should be noted that the cross-sectional shape of the outer groove plate 101 is not limited to a U-shape, but may be other shapes as long as there is a certain amount of space in the groove.

[0109] In one embodiment, if Figure 11-12 As shown, the inner moving member 104 is in the shape of an elongated strip, and a bulge 107 is provided in the center thereof, and side edges 108 are provided on both sides of the bulge 107.

Specifically, the outer groove plate 101 is provided with a first folded edge 102 on both sides along its length direction. The height, length and width of the outer groove plate 101 can be determined according to the size and weight of the object to be lifted. Generally, the length and width of the outer groove plate 101 should meet the requirement that the outer groove plate 101 can be completely placed on the bottom surface of the object to be lifted without being exposed. At the same time, the height of the outer groove plate 101 should also meet the requirement that the outer groove plate 101 can be installed on the bottom surface of the object to be lifted.

[0115] It should be noted that the cross-sectional shape of the outer groove plate 101 is not limited to a U-shape, but may be other shapes as long as there is a certain amount of space in the groove.
