[0031] In the embedded home, in order to improve the consistency of the overall style, the skirting line is installed at the lower part of the electrical equipment, and the height of the skirting line needs to be consistent with the height of the surrounding skirting line. In order to avoid the influence of the skirting line on the door opening and closing operation of the electrical equipment, the skirting line needs to be arranged below the door body of the electrical equipment, so that when the skirting line is installed on the electrical equipment, the electrical equipment needs to be lifted to the height of the skirting line by the lifting device. For example, the height of the skirting line is 80mm, and the height of the door body of the electrical equipment from the ground is 40mm, so that when the skirting line is installed, the electrical equipment needs to be lifted until the height of the door body is greater than 80mm, and a support seat is arranged at the bottom of the electrical equipment. After the skirting line is installed, the lifting device is removed, and the electrical equipment is supported on the support seat, so that the skirting line does not interfere with the opening and closing of the door body.

[0032] In the related art, the lifting device is realized by a worm gear or a cylindrical cam structure to realize the lifting function, and the volume and weight of the lifting device are large, which causes the installation personnel to carry inconveniently. In order to improve the problems existing in the related art to a certain extent, the lifting device provided in the embodiments of the present application reduces the volume and weight, and improves the carrying convenience of the workers.

[0033] The present application will be described below in conjunction with the drawings and specific embodiments:

[0034] Please refer to Figure 1 The lifting device 10 provided in the embodiments of the present application is used for installing electrical equipment. The lifting device 10 provided in the embodiments of the present application reduces the volume and weight, and improves the carrying convenience of the workers.

[0035] Among them, the electrical equipment can be a refrigerator, or a washing machine, a dishwasher and all other electrical equipment that can be embedded. In the embodiments of the present application, in order to facilitate the description, the electrical equipment is taken as a refrigerator for example, and when the electrical equipment is other equipment, it can be taken by analogy.

[0036] The refrigerator is approximately cuboid, and for the convenience of description, a height direction, a width direction and a thickness direction are defined, wherein in the use state of the refrigerator, the vertical direction is the height direction, the projection of the refrigerator in the vertical direction is a rectangle, the direction of the long side is the width direction, and the direction of the wide side is the thickness direction.

[0037] Similarly, for the convenience of description, six directions, i.e., up, down, left, right, front and back, are defined. In the height direction, the side close to the top surface is up, and the side close to the bottom surface is down. In the width direction, the two directions are left and right respectively. In the thickness direction, the side close to the door body of the refrigerator is front, and the opposite side is back.

[0038] Please refer to Figure 1 and Figure 2 In the embodiment of the present application, the lifting device 10 comprises a lifting assembly 100 and a gas bag assembly 200. The lifting assembly 100 comprises a bottom plate 110, a support plate 120 and a guide 130, the guide 130 movably connects the support plate 120 and the bottom plate 110, and the support plate 120 is used for supporting the electrical equipment; the gas bag assembly 200 is arranged between the bottom plate 110 and the support plate 120.

[0039] The gas bag assembly 200 can drive the support plate 120 to move away from the main body by inflation, so as to lift the electrical equipment.

[0040] The bottom plate 110 is the basic component of the lifting device 10, and can provide a mounting basis for other structures of the lifting device 10. The support plate 120 is arranged opposite to the bottom plate 110, and the side of the support plate 120 away from the bottom plate 110 is in contact with the refrigerator. The guide 130 movably connects the support plate 120 and the bottom plate 110, that is, one end of the guide 130 is connected with the support plate 120, and the other end is connected with the bottom plate 110, so that the support plate 120 and the bottom plate 110 form an integral whole, and in the process of the support plate 120 moving close to or away from the bottom plate 110, the guide 130 can move along with the support plate 120, so as to provide guidance for the movement of the support plate 120, and make the movement of the support plate 120 more stable.

[0041] The gas bag assembly 200 has an inflation state and a deflation state. When the gas bag assembly 200 is in the inflation state, the gas bag assembly 200 expands and the volume becomes larger, wherein the gas bag assembly 200 will be elongated in the height direction. When the gas bag assembly 200 is in the deflation state, the gas bag assembly 200 shrinks and the volume becomes smaller, and the gas bag assembly 200 will also be shortened in the height direction until there is almost no gas in the gas bag assembly 200, at which time the gas bag assembly 200 can be folded. Since the gas bag assembly 200 is arranged between the bottom plate 110 and the support plate 120, in the inflation process of the gas bag assembly 200, the support plate 120 will be driven to move away from the main body, and in the deflation process of the gas bag assembly 200, the support plate 120 will be driven to move close to the main body.

[0042] When installing the skirting line for the refrigerator, the lifting device 10 is pushed into the lower part of the refrigerator, wherein the bottom plate 110 is arranged on the ground, the support plate 120 is above the bottom plate 110, at this time, the air bag assembly 200 is inflated, the air bag assembly 200 is elongated in the height direction, thereby driving the support plate 120 to move upward to support and lift the refrigerator upward until the door body of the refrigerator is higher than the skirting line, at this time, the support seat is arranged at the bottom of the refrigerator to support the refrigerator, and the air bag assembly 200 is deflated, and the lifting device 10 is withdrawn from the lower part of the refrigerator.

[0043] As known from the above, the operator only inflates the air bag assembly 200 to lift the refrigerator when installing the skirting line, and in the carrying process, that is, the air bag assembly 200 is in the non-use state, the air bag assembly 200 can be folded up. Since the air bag assembly 200 is relatively light and has a small volume after being folded, the volume and weight of the lifting device 10 as a whole are greatly reduced, and the carrying convenience of the operator is improved.

[0044] Moreover, the air bag assembly 200 can be not connected with the support plate 120 and the bottom plate 110, so that the air bag assembly 200 can be carried separately from the lifting device 10, thereby further facilitating the operator to carry, and when the lifting device 10 needs to be used, the air bag assembly 200 can be placed between the bottom plate 110 and the support plate 120.

[0045] It should be noted that the bottom of the refrigerator is provided with wheels, so that there is a distance between the bottom of the refrigerator and the ground, and the lifting device 10 can be pushed into the distance between the bottom of the refrigerator and the ground. Since the support plate 120 and the bottom plate 110 are very close when the air bag assembly 200 is not inflated, that is, the height of the lifting device 10 is very low, so that the lifting device 10 can be conveniently pushed into the distance between the bottom of the refrigerator and the ground.

[0046] Please refer to Figure 2 and Figure 3 In some embodiments, the air bag assembly 200 includes an air bag 210, an inflating ball 220, an air pipe 230 and a valve 240, the air pipe 230 communicates the air bag 210 and the inflating ball 220, the valve 240 is arranged on the air pipe 230, the air bag 210 is arranged between the main body and the support plate 120, and the inflating ball 220 is arranged outside the bottom plate 110.

[0047] Since the air bag 210 is arranged between the main body and the support plate 120, the support plate 120 can be driven to move by inflating or deflating the air bag 210. The inflating ball 220 has gas, the valve 240 is closed, the inflating ball 220 is continuously squeezed, and the gas can enter the air bag 210 through the air pipe 230 to realize the inflation of the air bag 210; the valve 240 is opened, and the gas in the air bag 210 can escape through the air pipe 230 to realize the deflation of the air bag 210.

[0048] Since the lifting device 10 is arranged between the refrigerator and the ground, the air bag 220 is arranged outside the bottom plate 110, i.e. the air bag 220 is located outside the refrigerator, so that the worker can conveniently squeeze the air bag 220 to inflate the air bag 210.

[0049] Referring to Figure 2 and Figure 3 In some embodiments, the lifting device 10 further comprises a frame 140, and the lifting assembly 100 and the air bag assembly 200 are multiple, and the bottom plate 110 is mounted on the frame 140.

[0050] It can be understood that the lifting assembly 100 and the air bag assembly 200 are arranged one by one, and the air bag assembly 200 is arranged in the corresponding lifting assembly 100. In order to make the lifting process of the refrigerator more stable, the lifting device 10 needs to cover the bottom surface of the refrigerator as much as possible, and since the size of the air bag assembly 200 is limited, multiple lifting assemblies 100 and air bag assemblies 200 can be arranged to support the refrigerator together. In order to integrate multiple lifting assemblies 100 and air bag assemblies 200, each bottom plate 110 is mounted on the frame 140, so that multiple lifting assemblies 100 and air bag assemblies 200 are arranged in the frame 140.

[0051] Since the width direction size of the refrigerator bottom surface is greater than the thickness direction size, multiple lifting assemblies 100 can be arranged in the width direction, and two adjacent lifting assemblies 100 are arranged with a spacing, so that the lifting device 10 can cover the bottom surface of the refrigerator as much as possible, and the lifting stability of the refrigerator is improved.

[0052] In some embodiments, the bottom plate 110 can slide in the width direction of the frame 140.

[0053] Since different models of refrigerators may have different widths, in order to improve the versatility of the lifting device 10, the bottom plate 110 can slide in the width direction of the frame 140, so that the spacing between two adjacent lifting assemblies 100 can be adaptively adjusted according to the width of the refrigerator, so that the lifting device 10 can cover the bottom surface of different refrigerators as much as possible, and the lifting stability of the refrigerator is improved.

[0054] Referring to Figure 2 and Figure 3 In some embodiments, the lifting device 10 further comprises a fastener 160, the frame 140 has a sliding groove 150 arranged in the width direction, and the fastener 160 is slidably arranged in the sliding groove 150 and detachably connected with the frame 140 and the bottom plate 110.

[0055] Since the sliding groove 150 is arranged along the width direction, the fastener 160 is slidingly arranged in the sliding groove 150, so the fastener 160 can move along the width direction in the sliding groove 150. That is, when it is needed to adjust the position of the lifting assembly 100, the fastener 160 is disassembled, so that the frame 140 and the bottom plate 110 are separated, at this time, the bottom plate 110 is moved along the width direction, when the position of the bottom plate 110 is adjusted, the fastener 160 is moved in the sliding groove 150, and the fastener 160 is fixedly connected with the frame 140 and the bottom plate 110 after being moved to the position, so that the bottom plate 110 is fixedly installed in the frame 140.

[0056] It is conceived that since each bottom plate 110 needs to be moved along the width direction, the sliding groove 150 and the fastener 160 are arranged corresponding to each bottom plate 110, and the length of the sliding groove 150 is greater than the range that the bottom plate 110 needs to be moved.

[0057] Specifically, the fastener 160 can be a connecting bolt.

[0058] Please refer to Figure 2 and Figure 3 In some embodiments, the frame 140 comprises a connecting rod 143 and a pushing piece 141, the pushing piece 141 is provided with a holding opening 142, the connecting rod 143 is connected with one end of the plurality of bottom plates 110, the pushing piece 141 is connected with the other end of the plurality of bottom plates 110, and the sliding groove 150 is arranged between the connecting rod 143 and the pushing piece 141.

[0059] Since the plurality of bottom plates 110 are arranged along the width direction, the connecting rod 143 and the pushing piece 141 are respectively connected with the two ends of the bottom plate 110 along the thickness direction, so that the plurality of lifting assemblies 100 can be integrated together.

[0060] When the refrigerator needs to be lifted, the worker needs to push the lifting device 10 into the lower part of the refrigerator by hand, and after the skirting line is installed, the worker also needs to push the lifting device 10 out of the lower part of the refrigerator by hand, so the pushing piece 141 is provided with the holding opening 142, which can facilitate the worker to hold the lifting device 10. Of course, in the use state of the lifting device 10, the pushing piece 141 is located at the front side of the lifting device 10, that is, the pushing piece 141 faces the worker, so as to facilitate the worker to hold.

[0061] Since the bottom plate 110 is connected with the connecting rod 143 and the pushing piece 141, the sliding groove 150 needs to be arranged on the connecting rod 143 and the pushing piece 141, of course, the fastener 160 for connecting the pushing piece 141 or the connecting rod 143 is arranged in the sliding groove 150, so that when the bottom plate 110 slides along the width direction, the fastener 160 on the connecting rod 143 and the pushing piece 141 moves in the sliding groove 150.

[0062] Please refer to Figure 4 andFigure 5 In some embodiments, the end of the bottom plate 110 is provided with a flange 111, and the fastener 160 detachably connects the frame 140 and the flange 111.

[0063] The end surface of the bottom plate 110 is connected with the frame 140, and since the size of the end surface of the bottom plate 110 is small, it is inconvenient to directly connect the frame 140 and the bottom plate 110 with the fastener 160, and therefore the flange 111 is provided at the end of the bottom plate 110. The flange 111 is arranged at the end of the bottom plate 110 close to the sliding groove 150, and the flange 111 is arranged at an angle with the bottom plate 110 to increase the overlapping area of the flange 111 and the frame 140, and the thickness of the flange 111 is thin, which can facilitate the connection of the frame 140 and the flange 111 with the fastener 160.

[0064] Please refer to Figure 6 In some embodiments, the guide 130 includes a first connecting rod 131 and a second connecting rod 132 which are hinged, one end of the first connecting rod 131 is movably connected to the support plate 120, and the other end is fixedly connected to the main body; one end of the second connecting rod 132 is fixedly connected to the support plate 120, and the other end is movably connected to the main body.

[0065] That is, the guide 130 is a cross connecting rod structure, when the support plate 120 moves away from the bottom plate 110, one end of the first connecting rod 131 moves close to one end of the second connecting rod 132, and the other end of the second connecting rod 132 moves close to the other end of the first connecting rod 131, and the guide 130 is elongated accordingly; when the support plate 120 moves close to the bottom plate 110, one end of the first connecting rod 131 moves away from one end of the second connecting rod 132, and the other end of the second connecting rod 132 moves away from the other end of the first connecting rod 131, and the guide 130 is shortened accordingly, that is, the guide 130 can be stretched and contracted with the movement of the support plate 120, thereby providing guidance for the movement of the support plate 120, and making the movement of the support plate 120 more stable.

[0066] Specifically, the support plate 120 is provided with a first sliding groove 135, the bottom plate 110 is provided with a second sliding groove 136, one end of the first connecting rod 131 is provided with a first sliding part 133, and the other end of the second connecting rod 132 is provided with a second sliding part 134, the first sliding part 133 and the first sliding groove 135 are in sliding cooperation, and the second sliding part 134 and the second sliding groove 136 are in sliding cooperation, and therefore, under the sliding cooperation of the first sliding part 133 and the first sliding groove 135, the movement of one end of the first connecting rod 131 can be guided, and under the sliding cooperation of the second sliding part 134 and the second sliding groove 136, the movement of the other end of the second connecting rod 132 can be guided, thereby making the stretching and contraction of the guide 130 more stable.

[0067] Please refer to Figure 2 and Figure 3In some embodiments, the support plate 120 is provided with a guide 130 on both sides, and the air bag assembly 200 is arranged between the two guides 130.

[0068] The support plate 120 is provided with a guide 130 on both sides, so that the guiding effect on the support plate 120 can be improved, and the movement stability of the support plate 120 can be further improved. The air bag assembly 200 is arranged between the two guides 130, that is, the air bag assembly 200 is arranged at the middle position of the support plate 120, so that the lifting uniformity of the support plate 120 can be improved, and the support plate 120 can be kept as horizontal as possible during the movement, so that the refrigerator can be kept as horizontal as possible during the lifting, and the installation stability of the refrigerator can be improved.

[0069] Please refer to Figure 4 In some embodiments, the lifting assembly 100 further comprises a roller 170, and the roller 170 is arranged on the side of the bottom plate 110 away from the support plate 120.

[0070] Since the lifting device 10 needs to be manually pushed into or out of the lower part of the refrigerator, the roller 170 is arranged on the side of the bottom plate 110 away from the support plate 120, so that the pushing of the lifting device 10 can be more smooth and labor-saving. Specifically, since the lifting device 10 moves in the thickness direction during being pushed into or out of the lower part of the refrigerator, the roller 170 is arranged on both sides of the bottom plate 110 in the thickness direction, so that the movement of the lifting device 10 can be more smooth.
