[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] like Figures 1 to 9 As shown, in the technical scheme of embodiment 1, a mounting seat assembly 10 and a hook assembly 20, the hook assembly 20 is connected to the mounting seat assembly 10, the hook assembly 20 includes a first hook structure 21, a second hook structure 22 and a connecting rod 23, the first hook structure 21 is rotatably connected to the mounting seat assembly 10, the first end of the connecting rod 23 is rotatably connected to the first hook structure 21, the height of the first end of the connecting rod 23 in the vertical direction is higher than the height of the mounting seat assembly 10 in the vertical direction, the second hook structure 22 is rotatably connected to the mounting seat assembly 10, the second end of the connecting rod 23 is rotatably connected to the second hook structure 22, and the height of the second end of the connecting rod 23 in the vertical direction is lower than the height of the mounting seat assembly 10 in the vertical direction.

[0038] By applying the technical solution of the first embodiment, the mounting seat assembly 10 is fixed, and when the first hook structure 21 and the mounting seat assembly 10 rotate relative to each other, the connecting rod 23 is driven to rotate and translate, and the translation of the connecting rod drives the second hook structure 22 to rotate, so the first hook structure 21 and the second hook structure 22 rotate at the same time, realizing the coordinated control of the first hook structure 21 and the second hook structure 22. The technical solution of the first embodiment effectively solves the problem in the prior art that in the process of taking and placing the washing basket, there is a mistake in the process of taking and placing the washing basket due to the inability of the two sets of hooks to be coordinated, which leads to glass breakage.

[0039] like Figures 1 to 9As shown, in the technical scheme of embodiment one, the first hook structure 21 includes a first hook 211, a first connecting portion 212, a first rotating shaft 213 and a second rotating shaft 214, the first hook 211 is connected to the first connecting portion 212, the first connecting portion 212 is rotatably connected to the first rotating shaft 213, the first rotating shaft 213 is rotatably connected to the connecting rod 23, the first connecting portion 212 is rotatably connected to the second rotating shaft 214, the second rotating shaft 214 is rotatably connected to the mounting seat assembly 10, the height of the first rotating shaft 213 in the vertical direction is higher than the height of the second rotating shaft 214 in the vertical direction, and the axes of the two are parallel. The first hook 211 and the first connecting portion 212 are an integrally formed structure. Since the second rotating shaft 214 is rotatably connected to the mounting seat assembly 10, the mounting seat assembly 10 is fixed, and the second rotating shaft 214 only rotates without translation. Therefore, the first hook 211 and the first connecting portion 212 rotate about the axis of the second rotating shaft 214, and the spatial position of the first rotating shaft 213 changes, thereby changing the spatial position of the connecting rod 23. The arrangement of the first rotating shaft 213 and the second rotating shaft 214 realizes the connection between the first hook structure 21 and the connecting rod 2 3 and the rotatable connection of the mounting seat assembly 10, since the height of the first rotating shaft 213 in the vertical direction is higher than the second rotating shaft 214, the movement direction of the connecting rod 23 is opposite to that of the first hook 211, and the connecting rod 23 drives the second hook structure 22 to rotate, thereby realizing the coordinated control of the first hook 211 and the second hook structure 22. The two rotate synchronously, and the cleaning basket can be lifted and placed at the same time, with good coordination, avoiding the problem of uneven force on the cleaning basket and tipping over during the lifting of the cleaning basket due to the simultaneous operation of the two sets of hooks.

[0040] like Figures 1 to 9 As shown, in the technical solution of the first embodiment, the first hooks 211 include at least two, the first connecting parts 212 are arranged one by one corresponding to the first hooks 211, and the two first connecting parts 212 are rotatably connected to the two ends of the first rotating shaft 213. In order to ensure that the cleaning basket is subjected to uniform force, at least two first hooks 211 are provided, and the distance between adjacent first hooks 211 is set according to the size of the cleaning basket and the strength of the first hooks 211. The multiple first hooks 211 are all connected to the first rotating shaft 213, so the movement of the first rotating shaft 213 will drive all the first hooks 211 to rotate simultaneously, realizing the synchronous control of the multiple first hooks 211.

[0041] like Figures 1 to 9As shown, in the technical scheme of embodiment one, the second hook structure 22 includes a second hook 221, a second connecting portion 222, a third rotating shaft 223 and a fourth rotating shaft 224, the second hook 221 is connected to the second connecting portion 222, the second connecting portion 222 is rotatably connected to the third rotating shaft 223, the third rotating shaft 223 is rotatably connected to the mounting seat assembly 10, the second connecting portion 222 is rotatably connected to the fourth rotating shaft 224, the fourth rotating shaft 224 is rotatably connected to the connecting rod 23, the height of the third rotating shaft 223 in the vertical direction is lower than the height of the fourth rotating shaft 224 in the vertical direction, and the axes of the two are parallel. The second hook 221 and the second connecting portion 222 are an integrally formed structure. Since the third rotating shaft 223 is rotatably connected to the mounting seat assembly 10, the mounting seat assembly 10 is fixed, and the third rotating shaft 223 only rotates without translation. Therefore, when the position of the connecting rod 23 changes, the position of the fourth rotating shaft 224 also changes accordingly, driving the second hook 221 and the second connecting portion 222 to rotate around the axis of the third rotating shaft 223. Since the height of the third rotating shaft 223 in the vertical direction is lower than the height of the fourth rotating shaft 224 in the vertical direction, the movement directions of the connecting rod 23 and the second hook 221 are opposite. In summary, when the connecting rod 23 moves, the first hook 211 and the second hook 221 rotate at the same time and in opposite directions. The above structure can realize the synchronous control of the first hook 211 and the second hook 221, and the two move at the same time. In the process of lifting and placing the cleaning basket, the cleaning basket is evenly stressed and not easy to tip over.

[0042] like Figures 1 to 9 As shown, in the technical solution of the first embodiment, the second hook 221 includes at least two, the second hook 221 is arranged in a one-to-one correspondence with the first hook 211, the second hook 221 is arranged in a one-to-one correspondence with the second connecting portion 222, and the two second connecting portions 222 are rotatably connected to the two ends of the fourth rotating shaft 224. The first hook 211 and the second hook 221 are respectively arranged on both sides of the mounting seat assembly 10 and are arranged corresponding to the size of the cleaning basket, so as to realize the lifting and placement of the cleaning basket. The second hook 221 is arranged in a one-to-one correspondence with the first hook 211 to ensure that the pulling force on both sides of the cleaning basket is consistent, and avoid the cleaning basket from tipping over due to uneven force. The multiple second connecting portions 222 are all connected to the fourth rotating shaft 224, so when the fourth rotating shaft 224 moves, it drives all the second hooks 221 to rotate at the same time, realizing the synchronous control of the multiple second hooks 221. The above structure realizes synchronous control of the plurality of first hooks 211 and the plurality of second hooks 221, thereby providing sufficient and equal pulling force to both sides of the cleaning basket, thereby preventing the cleaning basket from tipping over.

[0043] like Figures 1 to 9As shown, in the technical solution of the first embodiment, the first hook 211 and the second hook 221 are arranged in a manner opposite to each other and have the same height in the vertical direction. Since the first hook 211 and the second hook 221 have opposite rotation directions, the arrangement of the two in a manner opposite to each other can realize the simultaneous grabbing of the cleaning basket. To ensure that the first hook 211 and the second hook 221 are in contact with both sides of the cleaning basket at the same time, the first hook 211 and the second hook 221 have the same height in the vertical direction. The above structure ensures the balance of the cleaning basket.

[0044] like Figures 1 to 9 As shown, in the technical solution of the first embodiment, the mounting seat assembly 10 includes a support structure 11 and a mounting seat structure 12, the mounting seat structure 12 is fixed on the support structure 11, and the hook assembly 20 is rotatably connected to the mounting seat structure 12. A bearing is provided on the mounting seat structure 12, and the setting of the bearing enables the hook assembly 20 to be subjected to a rotational friction force during the rotation process, so that the rotation is more stable, the wear is less, and the service life is longer. The support structure 11 provides support force for the hook assembly 20.

[0045] like Figures 1 to 9 As shown, in the technical solution of the first embodiment, the mounting seat structure 12 includes a first mounting seat 121 and a second mounting seat 122, the first mounting seat 121 is rotatably connected to the second rotating shaft 214, the second mounting seat 122 is rotatably connected to the third rotating shaft 223, the first mounting seat 121 and the second mounting seat 122 are respectively located on both sides of the support structure 11, and the height of the axis of the second rotating shaft 214 in the vertical direction is equal to the height of the third rotating shaft 223 in the vertical direction. The arrangement of the first mounting seat 121 and the second mounting seat 122 facilitates the arrangement of the second rotating shaft 214 and the third rotating shaft 223 on both sides of the support structure 11, and the distance between the first mounting seat 121 and the second mounting seat 122 is set according to the size of the cleaning basket. Dust shields are arranged on the first mounting seat 121 and the second mounting seat 122, and the arrangement of the dust shields reduces the dust from entering the bearing and hindering the rotation of the second rotating shaft 214 and the third rotating shaft 223.

[0046] like Figures 1 to 9 As shown, in the technical solution of the first embodiment, the support structure 11 has a long hole 111, and the connecting rod 23 is movably arranged in the long hole 111. The setting of the long hole avoids interference between the connecting rod 23 and the support structure 11.

[0047] like Figures 1 to 9As shown, in the technical solution of the first embodiment, the cleaning basket lifting device further includes a driving assembly 30 , the driving assembly 30 is fixed on the mounting seat assembly 10 , and the output end of the driving assembly 30 is connected to the first rotating shaft 213 . In the first embodiment, the driving component 30 uses a cylinder, and the output end of the cylinder is connected to the first rotating shaft 213. The cylinder extends to push the first rotating shaft 213. The movement of the first rotating shaft 213 drives the connecting rod 23 to move, and the first hook 211 and the first connecting part 212 rotate counterclockwise. At the same time, the second hook 221 and the second connecting part 222 rotate clockwise. When the maximum distance between the first hook 211 and the second hook 221 is less than the distance between the handles on both sides of the cleaning basket, the mounting seat assembly 10 is controlled to move downward to the cleaning basket, and the first hook 211 and the second hook 221 extend between the handles on both sides of the cleaning basket. The cylinder retracts, the first hook 211 and the second hook 221 are reset, and the maximum distance between the two is increased. The handles of the cleaning basket are stuck on the first hook 211 and the second hook 221, thereby realizing the lifting of the cleaning basket. The driving component 30 is also provided with an inductive sensor. After the inductive sensor detects the specific position of the cleaning basket, it feeds back a signal to the driving component 30 . The driving component 30 drives the hook component to lift. The setting of the driving component 30 and the inductive sensor realizes the automatic control of the hook component 20 .

[0048] It should be noted that in the technical solution of Example 1, the ratio of the distance d1 between the second rotating shaft 214 and the third rotating shaft 223 to the distance d2 between the handles on both sides of the washing basket is 1:1, and the ratio of the distance d3 between the first rotating shaft 213 and the second rotating shaft 214 to the distance d4 between the third rotating shaft 223 and the fourth rotating shaft 224 is 1:1.

[0049] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that in the technical solution of the second embodiment, the first hook 211 and the second hook 221 are arranged facing each other, and during the grabbing process, the driving assembly 30 contracts to control the minimum distance between the first hook 211 and the second hook 221 to increase, and the cleaning basket is grabbed from the outside of the cleaning basket. The technical solution of the second embodiment avoids the first hook structure 21 and the second hook structure 22 from hitting the glass during the movement, causing damage to the glass surface.

[0050] In summary, the cleaning basket lifting device provided by the present application uses a cylinder (drive component 30) and an anti-parallelogram linkage mechanism (hook component 20) to achieve the function of picking up and releasing materials, and the linkage mechanism (hook component 20) is relatively stable. When the product needs to be taken out of the cleaning tank, the cylinder is controlled by the solenoid valve, and the cylinder is retracted, driving two sets of rotating shafts and two sets of hooks (first hook structure 21 and second hook structure 22) to rotate along the bearing seat (mounting seat structure 12), and the hooks (first hook 211 and second hook 221) hook the cleaning basket. When the induction sensor is triggered, the hook is in the state of picking up the cleaning basket; when the product needs to be put down, the cylinder is controlled by the solenoid valve, and the cylinder is extended, driving two sets of rotating shafts and two sets of hooks to rotate along the bearing seat, and the hook will be unhooked from the cleaning basket. When the induction sensor is triggered, the hook is in the state of releasing the cleaning basket. The present application uses a set of cylinders as the power and an anti-parallelogram connecting rod mechanism as the moving body to drive two sets of hooks to move synchronously, thereby achieving the functions of taking and placing the cleaning basket. This mechanism has high stability, is simple and easy to maintain, and has low maintenance costs for enterprises.
