Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a mobile bracket with a foldable handle 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, it is inconvenient to move or it takes time and effort to move. Therefore, a solution of installing a mobile bracket at the bottom of the household appliance has emerged. Such a mobile bracket has a handle and a lifting mechanism. The handle can be turned to raise the roller in the lifting mechanism, and then the household appliance can be lifted. At this time, the household appliance can be moved by dragging such a mobile bracket.

[0003] The Chinese utility model patent with application number 202220571157X discloses a washing machine carrying and moving mechanism, including a main carrying plate, a roller, a wheel axle, a wedge block and a handle. The upper surface of the main carrying plate is a bearing surface, which is used to support the bottom surface of the washing machine. The lower surface is provided with a horizontal slide groove, and the side of the slide groove is provided with a guide part, and the guide part is provided with a horizontal wheel axle. The guide part can guide the wheel axle in the vertical direction, and the axial direction of the wheel axle is perpendicular to the length direction of the slide groove. A roller is provided at each end of the wheel axle. A wedge block is provided in the slide groove, and the wedge block is located below the wheel axle. The inclined surface of the wedge block is tangent to the wheel axle, and one end of the wedge block is connected to the handle.

[0004] For example, the Chinese utility model patent with application number 2022217823631 discloses a sloped movable bracket, including a first slot plate for connecting household appliances, a second slot plate located in the first slot plate and slidable relative to the first slot plate, a plurality of movable components evenly spaced on the first slot plate and the second slot plate and used for lifting and moving household appliances, and a wrench assembly for driving the second slot plate to slide.

[0005] The mobile brackets in the prior art all have a wrench, and by rotating the wrench, the roller on the lifting mechanism is driven to rise. In order to increase the torque and achieve the effect of labor saving, the wrench is often longer. For such mobile brackets, whether the wrench is rotated to a vertical state with the bracket body or to a horizontal state with the bracket body, the longer wrench is obviously not conducive to storage, packaging, and transportation. At the same time, since the wrench is connected to the linkage part by transmission, if all parts of the wrench assembly can be separated from the bracket body, when the mobile bracket needs to be used, the assembly of the wrench assembly is difficult, that is, it is not convenient to use.

[0058] 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.

[0059] 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.

[0060] In one embodiment, if Figure 3-7 As shown, the utility model proposes a mobile support with a folding handle, comprising an outer groove plate 101, an inner moving member 102, a lifting mechanism and a wrench assembly, wherein the wrench assembly comprises a rotating portion 201, a handle portion 301 and a locking mechanism. The rotating portion 201 is always hinged with the outer groove plate 101, that is, the rotating portion 201 can rotate relative to the outer groove plate 101. At the same time, the rotating portion 201 is always connected to the inner moving member 102 by transmission, and the transmission connection here refers to that when the rotating portion 201 rotates, the inner moving member 102 can be driven to slide along the outer groove plate 101.

[0061] The lifting mechanism is partially connected with the inner moving member 102 and partially connected with the outer groove plate 101. When the inner moving member 102 slides along the outer groove plate 101, the lifting mechanism connected with the outer groove plate 101 and the inner moving member 102 can raise or lower the outer groove plate 101. When the inner moving member 102 slides toward one end of the outer groove plate 101, the roller 107 in the lifting mechanism rises, so that the outer groove plate 101 is raised; when the inner moving member 102 slides toward the other end of the outer groove plate 101, the roller 107 in the lifting mechanism falls, so that the outer groove plate 101 is lowered.

[0062] It should be noted that in this embodiment, the handle portion 301 is hinged to the rotating portion 201 via the first hinge point 206, that is, the handle portion 301 can rotate relative to the rotating portion 201. In addition, the locking mechanism can enable the handle portion 301 and the rotating portion 201 to rotate synchronously.

[0063] When the mobile bracket is not needed, the locking mechanism can be in an unlocked state, that is, the handle portion 301 can rotate relative to the rotating portion 201. Figure 3 , 6 As shown, the handle portion 301 can be rotated to a folded state, and the mobile bracket is relatively compact as a whole, which is convenient for storage, packaging and transportation.

[0064] When the mobile bracket is used, the locking mechanism can be locked, that is, the handle portion 301 and the rotating portion 201 can rotate synchronously, and the handle portion 301 cannot rotate relative to the rotating portion 201. Figure 4 , 5 As shown in FIG. 7 , when the handle portion 301 is rotated, the rotating portion 201 will also rotate, thereby driving the inner moving member 102 to slide along the outer groove plate 101, thereby raising or lowering the outer groove plate 101.

[0065] In one embodiment, the locking mechanism includes a first connection portion 205 provided on the rotating portion 201, and the handle portion 301 is provided with a second connection portion 302 adapted to the first connection portion 205. When the handle portion 301 needs to be rotated synchronously with the rotating portion 201, the rotating portion 201 and the handle portion 301 are connected through the first connection portion 205 and the second connection portion 302.

[0066] Through holes may be provided at the first connection portion 205 and the second connection portion 302 , and then nuts may be used in conjunction with bolts passing through the through holes to connect the rotating portion 201 and the handle portion 301 together to achieve synchronous rotation.

[0067] One of the first connection part 205 or the second connection part 302 may be a groove, and a spring plunger may be installed at the other part. When the handle part 301 is rotated to a corresponding position, the rotating part 201 and the handle part 301 may be connected together to realize synchronous rotation.

[0068] It should be noted that the first connection portion 205 and the second connection portion 302 are not limited to the above two methods. Other connection methods that can achieve similar functions are relatively mature in the prior art and will not be described in detail here.

[0069] like Figure 6-7 As shown, there can be at least two first connection parts 205. In this embodiment, there are two first connection parts 205, which are arranged at intervals, and the number of second connection parts 302 matches the number of first connection parts 205. Multiple first connection parts 205 and second connection parts 302 can improve the stability of the connection between the handle part 301 and the rotating part 201.

[0070] Another example Figure 3-5 As shown, only one first connection portion 205 may be provided, and the number of second connection portions 302 matches the number of first connection portions 205. In this embodiment, an arcuate transition section 207 and an avoidance groove 208 adjacent to the arcuate transition section 207 are provided on one side of the rotating portion 201.

[0071] In this embodiment, handle folds 304 are provided on both sides of the handle portion 301 , and the structural strength of the handle can be improved by providing the handle folds 304 . The arc-shaped transition section 207 and the avoidance groove 208 are used to avoid the handle folds 304 .

[0072] The rotating part 201 is provided with an arcuate transition section 207 and an avoidance groove 208 for avoiding the handle fold 304, so that the first hinge point 206 of the handle 301 and the rotating part 201 can be as far away from the third hinge point 104 of the connecting rod and the rotating part 201 as possible without reducing the length of the handle fold 304 (i.e. without reducing the structural strength of the handle), that is, L1 is smaller and L2 is increased. When L2 is increased, the stroke of the inner moving part 102 can be increased when the rotating part 201 rotates. When the stroke of the inner moving part 102 is increased, it helps to increase the lifting height of the roller 107 in the lifting mechanism.

[0073] When the rotating part 201 is provided with an arc-shaped transition section 207 and an avoidance groove 208 , interference between the rotating part 201 and the handle fold 304 can be avoided, thereby not reducing the strength of the handle and also facilitating the increase of the stroke of the inner moving part 102 .

[0074] In one embodiment, if Figure 5 As shown, when the rotating part 201 rotates to be substantially vertical to the outer groove plate 101, the other side of the rotating part 201 is substantially flush with the end of the outer groove plate 101. In this state, the other side of the rotating part 201 is substantially flush with the end of the outer groove plate 101, that is, there is no obvious protrusion, which can make the overall shape of the mobile bracket more integrated and save space.

[0075] In one embodiment, if Figure 8-9 As shown, a rotation shaft limiting groove 209 is provided on the rotating part 201, and the first hinge point 206 is a rotation shaft passing through the rotation shaft limiting groove 209. Here, the rotation shaft refers to the rotation shaft through which the handle part 301 can rotate relative to the rotating part 201. The rotation shaft can be fixedly connected to the handle part 301, or it can rotate relative to the handle part 301. Limiting flanges should be provided at both ends of the rotation shaft so that the handle part 301 will not be separated from the rotating part 201.

[0076] The handle portion 301 can rotate relative to the rotating portion 201 , and can also slide relative to the rotating portion 201 along the rotation shaft limiting groove 209 .

[0077] The locking mechanism includes a second plug block 305 provided on the handle portion 301, and the rotating portion 201 is provided with a second slot 210 adapted to the shaft limit slot 209. The handle portion 301 is rotated and slid along the shaft limit slot 209 so that the second plug block 305 is aligned with the second slot 210. Then the handle portion 301 is slid along the shaft limit slot 209 so that the second plug block 305 is inserted into the second slot 210, and the handle portion 301 and the rotating portion 201 can be rotated synchronously.

[0078] like Figure 8-9 As shown, the second slot 210 is a straight slot.

[0079] like Fig.12 As shown, the second slot 210 can have one section as a straight slot and the other section as an arc slot, and the arc slot is provided with an opening, the handle portion 301 is rotated to insert the second plug block 305 into the arc slot, and then the handle portion 301 is continued to be rotated to align the second plug block 305 with the straight slot, and then the handle portion 301 is pulled to stagger the second plug block 305 with the arc slot, so that the handle portion 301 and the rotating portion 201 can be rotated synchronously.

[0080] In one embodiment, if Figure 10-11 As shown, a rotation shaft limiting groove 209 is provided on the rotating part 201, and the first hinge point 206 is a rotation shaft passing through the rotation shaft limiting groove 209. Here, the rotation shaft refers to the rotation shaft through which the handle part 301 can rotate relative to the rotating part 201. The rotation shaft can be fixedly connected to the handle part 301, or it can rotate relative to the handle part 301. Limiting flanges should be provided at both ends of the rotation shaft so that the handle part 301 will not be separated from the rotating part 201.

[0081] The locking mechanism includes a limiting column 306 connected to the handle portion 301, and the limiting column 306 can be fixedly connected to the handle portion 301. The rotating portion 201 is provided with an arc guide groove 211 for the limiting column 306 to pass through. When the handle portion 301 rotates relative to the rotating portion 201, the limiting column 306 moves along the arc guide groove 211.

[0082] The rotating part 201 is also provided with a limiting column limiting groove 212, which is matched with the rotating shaft limiting groove 209 and communicated with the arc guide groove 211. When the handle part 301 is rotated until the limiting column 306 is aligned with the limiting column limiting groove 212, the handle part 301 is slid along the limiting column limiting groove 212 and the rotating shaft limiting groove 209 relative to the rotating part 201, so that the limiting column 306 enters the limiting column limiting groove 212, and the handle part 301 and the rotating part 201 can be rotated synchronously.

[0083] In one embodiment, if Figure 1-2 As shown, the utility model provides a mobile bracket with a folding handle, comprising an outer groove plate 101, an inner moving member 102, a lifting mechanism and a wrench assembly, wherein the wrench assembly comprises a rotating portion 201 and a handle portion 301. The rotating portion 201 is always hinged with the outer groove plate 101, that is, the rotating portion 201 can rotate relative to the outer groove plate 101. At the same time, the rotating portion 201 is always in transmission connection with the inner moving member 102, and the transmission connection here means that when the rotating portion 201 rotates, the inner moving member 102 can be driven to slide along the outer groove plate 101.

[0084] The lifting mechanism is partially connected with the inner moving member 102 and partially connected with the outer groove plate 101. When the inner moving member 102 slides along the outer groove plate 101, the lifting mechanism connected with the outer groove plate 101 and the inner moving member 102 can raise or lower the outer groove plate 101. When the inner moving member 102 slides toward one end of the outer groove plate 101, the roller 107 in the lifting mechanism rises, so that the outer groove plate 101 is raised; when the inner moving member 102 slides toward the other end of the outer groove plate 101, the roller 107 in the lifting mechanism falls, so that the outer groove plate 101 is lowered.

[0085] It should be noted that, in this embodiment, the handle portion 301 is detachably connected to the rotating portion 201. The detachable connection here means that the detached handle portion 301 can be installed on the rotating portion 201.

[0086] Before using the mobile bracket, the handle portion 301 is disconnected from the rotating portion 201. Figure 1 As shown, the separated handle portion 301 can be stacked together with the bracket to facilitate storage, packaging and transportation.

[0087] When the mobile bracket is needed, that is, when the handle 301 is needed to drive the rotating part 201 to rotate, the handle 301 can be connected to the rotating part 201. Figure 2 shown.

[0088] In this embodiment, the rotating part 201 is provided with a first connecting part 205, and the handle part 301 is provided with a second connecting part 302 adapted to the first connecting part 205. The rotating part 201 and the handle part 301 are connected through the first connecting part 205 and the second connecting part 302.

[0089] Through holes may be provided at the first connection portion 205 and the second connection portion 302 , and then nuts may be used in conjunction with bolts passing through the through holes to connect the rotating portion 201 and the handle portion 301 together to achieve synchronous rotation.

[0090] One of the first connection part 205 or the second connection part 302 may be a groove, and a spring plunger may be installed at the other part. When the handle part 301 is rotated to a corresponding position, the rotating part 201 and the handle part 301 may be connected together to realize synchronous rotation.

[0091] It should be noted that the first connection portion 205 and the second connection portion 302 are not limited to the above two methods. Other connection methods that can achieve similar functions are relatively mature in the prior art and will not be described in detail here.

[0092] In order to improve the stability of the connection between the handle part 301 and the rotating part 201, the rotating part 201 is provided with a first slot 203, and the handle part 301 is provided with a first plug block 303 adapted to the first slot 203. When the handle part 301 and the rotating part 201 are installed together, the first plug block 303 is first inserted into the first slot 203, and then the rotating part 201 and the handle part 301 are connected together through the first connecting part 205 and the second connecting part 302. When the handle part 301 is pulled to drive the rotating part 201 to rotate, the first plug block 303 abuts against the side wall of the first slot 203, thereby improving the stability of the connection between the handle part 301 and the rotating part 201.

[0093] In one embodiment, handle folds 304 are provided on both sides of the handle portion 301, and a limiting groove is formed between the handle folds 304. The rotating portion 201 is provided with a limiting protrusion 204 adapted to the limiting groove, and the first connecting portion 205 is provided at the limiting protrusion 204. When the handle portion 301 is pulled to drive the rotating portion 201 to rotate, the limiting protrusion 204 abuts against the side wall of the handle fold 304, thereby improving the stability of the connection between the handle portion 301 and the rotating portion 201.

[0094] In one embodiment, the rotating part 201 has a second hinge point 202 and a third hinge point 104, wherein the rotating part 201 is hinged to the outer groove plate 101 through the second hinge point 202, the rotating part 201 is hinged to one end of the connecting rod through the third hinge point 104, and the other end of the connecting rod is hinged to the inner moving part 102.

[0095] The first hinge point 206, the second hinge point 202 and the third hinge point 104 can all be realized by installing structures such as rivets and rotating shafts, which are relatively mature in the prior art and will not be described in detail here.

[0096] The handle 301 also has a force application point. Generally, the force application point is the gripping part of the handle 301 .

[0097] The force application point and the third hinge point 104 are located on the same side of the second connection point 202 , or are located on both sides of the second connection point 202 .

[0098] When the force application point and the third hinge point 104 are located on the same side of the second connection point 202, when the rotating part 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 part 102 is pulled. Figure 1-11 The figures all show the state where the inner moving member 102 is pulled.

[0099] When the force application point and the third hinge point 104 are located on both sides of the second connection point 202, when the rotating part 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 part 102 is pushed. This state is not shown in the figure. It should be understood that Figure 1-11 The third hinge point 104 in the joint moves to the other side of the second connection point 202 , and at this time, the connecting rod connected to the third hinge point 104 is also located on the other side of the second connection point 202 .

[0100] 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 inner moving member 102. 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.

[0101] 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.

[0102] In one embodiment, the lifting mechanism includes a ramp block 108 arranged on the inner moving member 102, and the lifting mechanism also includes a swing plate 106 hinged with the outer groove plate 101 through a connecting shaft 105, one end of the swing plate 106 is hinged with the connecting shaft 105, and the other end is provided with a roller 107. When the ramp block 108 moves toward the swing plate 106, the swing plate 106 is rotated by abutment, thereby raising the roller 107. When the ramp block 108 moves in the opposite direction, the roller 107 falls. In another embodiment, the swing plate 106 can be hinged with the inner moving member 102, and the ramp block 108 is arranged on the outer groove plate 101.

[0103] Figure 1-11 The structure shown in FIG. 1 is the arrangement direction of the ramp block 108 and the swing plate 106 when the rotating part 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101 so that the inner moving part 102 is pulled. When the rotating part 201 rotates from a state perpendicular to the outer groove plate 101 to a state parallel to the outer groove plate 101 so that the inner moving part 102 is pushed, the arrangement direction of the ramp block 108 and the swing plate 106 should be the same as the arrangement direction of the ramp block 108 and the swing plate 106. Figure 1-11 The opposite is true.

[0104] It should be noted that the lifting mechanism is not limited to the above structure, and other lifting mechanisms in the prior art can also be applied to the present mobile bracket, for example, the lifting mechanism includes two folding plates, one end of the two folding plates is respectively connected to the outer groove plate 101 and the inner moving member 102, and the other ends of the two folding plates are coaxially hinged. A roller is installed on one of the two folding plates, or on the connecting shaft of the two folding plates coaxially hinged. This structure has been disclosed in the prior art and will not be repeated here.

[0105] In one embodiment, the inner moving member 102 may be a slot plate, such as Figure 1-11 In another embodiment, the inner moving member 102 may also be a strip-shaped plate-like member (not shown), and this strip-shaped plate-like member may be arranged at the middle of the inner wall of the outer groove plate 101, or may be arranged at both sides of the outer groove plate 101. It should be noted that when the inner moving member 102 is a strip-shaped plate-like member arranged at both sides of the outer groove plate 101, the ramp block 108 is only arranged on the outer groove plate 101.

[0106] In one embodiment, the rotating part 201 and the inner moving part 102 may also be transmitted without using a connecting rod. For example, a guide groove may be set in the rotating part 201, and the third hinge point 104 is a guide column inserted into the guide groove. The guide column is connected to the inner moving part 102, and the rotating part 201 is rotated to pull the inner moving part 102 to move. This structure is relatively mature in the prior art and will not be repeated here.

[0107] In one embodiment, a locking mechanism may be provided in the rotation shaft limiting groove 209. When the handle portion 301 is unfolded, the locking mechanism is used to prevent the handle portion 301 from moving relative to the rotating portion 201 due to factors such as vibration, thereby ensuring that the handle portion 301 and the rotating portion 201 are in a synchronous rotation state. In this embodiment, the locking mechanism may be a plastic or rubber plug. Inserting the plug into the rotation shaft limiting groove 209 may prevent the handle portion 301 from moving relative to the rotating portion 201 due to factors such as vibration.

[0108] In one embodiment, the utility model further provides a household appliance, comprising a body, and also comprising a mobile bracket in any one of the above embodiments, the mobile bracket being used to lift and move the body. A foot may be provided at the bottom of the body, and when the household appliance is not lifted, the foot is in contact with the bottom surface. When the household appliance needs to be lifted and moved, the mobile bracket can lift the body of the household appliance, and the foot of the household appliance is not in contact with the ground, and then the household appliance can be moved relatively easily by means of the roller 107.

[0109] Specifically, the two ends of the outer groove plate 101 are provided with bayonet holes 103 for connecting with the bottom of the body. For example, the outer groove plate 101 can be connected with the body of the household appliance by passing bolts through the bayonet holes 103, and then tightened with nuts to fix. It should be noted that the outer groove plate 101 is not limited to the above connection method, and any fixing method that can achieve the connection between the outer groove plate 101 and the body can be used, which will not be repeated here.

[0110] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
