[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0028] like Figure 1 , Figure 2 , Fig.11 , Fig.12 As shown, a screen cabinet in-place transfer device includes a lifting column unit 23, a support unit 24 and a mobile base. The mobile base can move on the ground, the lifting column unit 23 is arranged on the mobile base, the support unit 24 is located on the lifting column unit 23, and the cabinet 1 is suspended on the support unit 24. The lifting column unit 23 telescopically moves to change the distance between the support unit 24 and the ground. When the device is not in a working state, changing the distance between the support unit 24 and the seat 7 can reduce the size of the space occupied by the device. When the device is in a working state, the support unit 24 can be used to hang the cabinet 1.

[0029] In this embodiment, Figure 2 , Figure 5 , Figure 7 , Figure 8 As shown, the mobile base includes a base body 7 and two legs 4 that can slide horizontally relative to each other to change the distance between them. Each leg 4 includes a sliding member 8 slidably assembled on the base body 7 and a supporting member 9 fixed on the sliding member 8. The two sliding members 8 slide on the base body 7 to change the relative distance between the two supporting members 9. A plurality of wheels 10 are provided on the supporting member 9 of each leg 4 to facilitate the movement of the entire device. In this embodiment, two wheels 10 are spaced apart on each supporting member 9 to support the entire device.

[0030] The two legs 4 can slide in relative directions through the corresponding sliding members 8. When the transfer equipment is not needed, the two legs 4 can be moved closer to each other, thereby reducing the space occupied by the two legs 4 in their sliding directions, which is conducive to full utilization of the space.

[0031] In this embodiment, Fig. 9 , Fig.10As shown, the seat body 7 has a sliding cavity, one of the sliding members 8 has an inner cavity 29, the sliding member 8 with the inner cavity 29 slides in the sliding cavity, and the other sliding member 8 is inserted and slides in the inner cavity 29, that is, the seat body 7 is sleeved on the outside of the sliding member 8 with the inner cavity 29, and the sliding member 8 with the inner cavity 29 is sleeved on the outside of the other sliding member 8. Such mutual sleeve connection can increase the sliding distance between the two legs 4, so that the device of this embodiment can be applied to a cabinet 1 of a larger specification.

[0032] In other embodiments, the two sliding members 8 are in contact with the sliding cavity at the same time and slide in the sliding cavity.

[0033] like Figure 2-Figure 4 As shown, a locking member is provided on the seat body 7, and the locking member is used to fix the seat body 7 and the two sliding members 8 together. In this embodiment, the locking member includes two bolts 17 threadedly connected to the seat body 7, and a plurality of spaced limiting holes 18 are provided on the two sliding members 8, and the arrangement direction of the limiting holes 18 is consistent with the sliding direction of the sliding member 8. The bolt 17 rotates on the seat body 7 so that the bolt 17 can be pressed into the corresponding limiting hole 18, thereby achieving the fixing of the corresponding sliding member 8. When it is necessary to adjust the distance between the two legs 4, the bolt 17 can be loosened, and the two sliding members 8 can be pulled to slide. When the two legs 4 are adjusted to a suitable distance, the bolt 17 can be tightened to fix the two legs 4. When the locking member is locked in this way, the equipment can be more stably suspended in the cabinet 1, and the lower plate of the equipment can be more stable.

[0034] The two sliding members 8 are both provided with a long hole 28, and the length direction of the long hole 28 is consistent with the sliding direction of the sliding member 8. The seat body 7 is provided with a pin hole 27, and a pin shaft is passed through the pin hole 27. The pin shaft passes through the sliding cavity, and the pin shaft also passes through the long hole 28 on the sliding member 8 at the same time, so that the sliding distance between the two legs 4 is the sum of the lengths of the two long holes 28. At the same time, even if the two sliding members 8 slide on the seat body 7, the two sliding members 8 will not slide off the seat body 7. In this embodiment, the pin shaft can be removed from the seat body 7. For example, the pin shaft includes a shaft body and a first nut located at both ends of the shaft body, and the first nut is threadedly connected to the two ends of the shaft body, so as to realize the disassembly of the pin shaft.

[0035] In this embodiment, the lifting column unit 23 includes a column 11 and a moving column 12 sliding on the column 11 along the extension direction thereof, a spring pin 22 is provided on the column 11, and a support unit 24 is provided on the moving column 12. The column 11 is rotatably assembled on the seat 7 via a first rotating shaft, and the column 11 rotates around the first rotating shaft so that the lifting column unit 23 can be switched between horizontal extension and vertical extension, wherein the lifting column unit 23 is in a folded state when it is in a horizontal extension, thereby reducing the space occupied by the lifting column unit 23 in the vertical direction; and the lifting column unit 23 is in an unfolded state when it is in a vertical extension.

[0036] In this embodiment, the first rotating shaft is always in a horizontally extended state, and the axis extension direction of the first rotating shaft is consistent with the sliding direction of the sliding member 8 .

[0037] In this embodiment, Figure 5-Figure 7 As shown, two mounting plates 19 are provided on the seat body 7. The two mounting plates 19 are vertically spaced and parallel to each other. The column 11 is rotatably assembled between the two mounting plates 19 via a first rotating shaft.

[0038] like Figure 4 As shown, the mounting plate 19 has a first through hole 20 and a second through hole 21 for inserting a spring pin 22. The column 11 rotates around the first rotation axis so that the spring pin 22 can be inserted and changed between the first through hole 20 and the second through hole 21. When the spring pin 22 is inserted into the first through hole 20, the lifting column unit 23 extends in the vertical direction. When the spring pin 22 is inserted into the second through hole 21, the lifting column unit 23 extends in the horizontal direction. When the cabinet 1 needs to be moved, the spring pin 22 is inserted into the first through hole 20, so that the lifting column unit 23 is in a vertical state. When the cabinet 1 does not need to be moved, the spring pin 22 is inserted into the second through hole 21, so that the lifting column unit 23 is in a horizontal state.

[0039] The column 11 is provided with a linear drive 13, which is connected to the moving column 12 to drive it to move. The linear drive 13 directly drives the moving column 12 to move, eliminating manual labor. The linear drive 13 in this embodiment is a hydraulic drive, which is consistent with the drive on a manual hydraulic forklift.

[0040] In this embodiment, the movable column 12 has a plug-in cavity, the support unit 24 is inserted into the plug-in cavity, and a pressing hand wheel 15 is threadedly connected to the movable column 12, and the pressing hand wheel 15 is rotated to press the support unit 24 in the plug-in cavity. The pressing hand wheel 15 can press on the support unit 24 through the rotation action, thereby fixing the support unit 24 on the movable column 12, thereby preventing the support unit 24 from shaking; when it is necessary to adjust the extension height of the support unit 24, the pressing hand wheel 15 can be rotated so that it no longer presses the support unit 24, and then the extension distance of the support unit 24 can be manually adjusted, and then the pressing hand wheel 15 can be used to press and fix the support unit 24.

[0041] The column 11 is provided with a slide groove for sliding the moving column 12, and the linear drive member 13 is arranged in the slide groove to drive the moving column 12 to move in the slide groove. Both the column 11 and the moving column 12 are provided with weight-reducing holes to reduce the weight of the entire device.

[0042] The rotating end of the column 11 has a first avoidance slope, and a second avoidance slope is provided on the seat body 7 corresponding to the first avoidance slope, so that when the column 11 rotates around the first rotation axis, the first avoidance slope and the second avoidance slope can avoid each other and will not affect the rotation of the column 11.

[0043] like Figure 5 , Fig.11 , Fig.12 As shown, the support unit 24 includes a connecting seat 14 arranged on the movable column 12 and two cantilevers 5 arranged on the connecting seat 14. The connecting seat 14 is inserted into the plug-in cavity. Each cantilever 5 has an unfolded state and a folded state. When the cantilever 5 is in the unfolded state, the cabinet 1 can be suspended on the two cantilevers 5 for the cabinet 1 to move. When the cantilever 5 is in the folded state, the two cantilevers 5 are folded on the connecting seat 14.

[0044] In this embodiment, when the device is in the unfolded state, the cabinet 1 can be hung on the two cantilevers 5. At this time, the two legs 4 are far away from each other to ensure that the cabinet 1 to be hung can be supported. The lifting column unit 23 extends in the vertical direction, and the lifting column unit 23 is telescoped to a height suitable for hanging the cabinet 1. At the same time, the two cantilevers 5 are unfolded, and the two cantilevers 5 are parallel to each other; when the device is in the folded state, the device reduces the occupied space. At this time, the distance between the two legs 4 is the shortest, the lifting column unit 23 extends horizontally, and the two cantilevers 5 are folded on opposite sides of the connecting seat 14.

[0045] In this embodiment, Figure 12-14As shown, each cantilever 5 is provided with a waist-shaped hole 25 at the first end, and two detachable second rotating shafts are provided on opposite sides of the connecting seat 14. When the device described in this embodiment is in use, the axes of the two second rotating shafts extend in the vertical direction. The second rotating shaft in this embodiment can be a screw rod, which passes through the connecting seat 14. At the same time, two second nuts are provided at both ends of the screw rod. By screwing the two second nuts, the screw rod can be removed from the connecting seat 14. The two second rotating shafts on the same side are inserted into the waist-shaped holes 25 of the corresponding cantilever 5 so that the two cantilevers 5 can be fixed on the connecting seat 14. The length of the waist-shaped hole 25 is consistent with the distance between the two second rotating shafts on the same side. Removing one second rotating shaft on the same side allows the cantilever 5 to rotate around the remaining second rotating shaft on one side of the connecting seat 14, so that the two cantilevers 5 can be folded on the connecting seat 14, reducing the size of the space occupied by the support unit 24 (the space in the extension direction of the cantilever 5). By providing a waist-shaped hole 25 and inserting two detachable second rotating shafts into the waist-shaped hole 25 , and removing one second rotating shaft, the cantilever 5 can be rotated around the remaining second rotating shaft, thereby realizing the folding of the cantilever 5 on the connecting seat 14 .

[0046] In this embodiment, it is defined that: the sliding direction of the two sliding members 8 is the left-right direction; when the device is working, the extension direction of the cantilever 5 is the front-back direction, and the telescopic direction of the lifting column unit 23 is the up-down direction. When the cantilever 5 needs to be folded, a rear second rotating shaft needs to be unplugged on the left side of the connecting seat 14, and the left cantilever 5 rotates 270 degrees around the remaining front second rotating shaft and folds on the connecting seat 14; a front second rotating shaft needs to be unplugged on the right side of the connecting seat 14, and then the rear second rotating shaft slides along the waist-shaped hole 25 on the right cantilever 5, and the cantilever 5 moves backward. When the second rotating shaft moves to one end of the waist-shaped hole 25, the cantilever 5 is rotated 90 degrees around the rear second rotating shaft and folded on the connecting seat 14. The two cantilevers 5 in this embodiment are folded on the opposite sides of the connecting seat 14, that is, the front and back sides. The two cantilevers 5 after folding are parallel to the first rotating shaft.

[0047] The suspension side of each cantilever 5 is provided with an anti-skid layer 16 for preventing the suspended cabinet 1 from sliding. The cabinet 1 is heavy, and the anti-skid layer 16 can be added to prevent the cabinet 1 from sliding on the cantilever 5, so that the transportation of the cabinet 1 can be made more stable and safe.

[0048] A limiting member 6 is provided on the second end of each cantilever 5 , and the limiting member 6 is used to limit the cabinet 1 from sliding off the cantilever 5 .

[0049] In this embodiment, the distance between the two legs 4 can be changed. When the equipment is needed, the space occupied by the two legs 4 can be reduced; the lifting column unit 23 can not only be extended and retracted, but also can be transformed from a vertical state to a horizontal state, thereby reducing the space occupied by the lifting column unit 23 in the up and down directions; the two cantilevers 5 can be folded onto the connecting seat 14, thereby reducing the space occupied by the support unit 24; the above method reduces the occupied space of the entire equipment, so that the entire space can be more fully utilized.

[0050] like Figure 15-17 As shown, the screen cabinet in-place transfer device described in this embodiment can be placed in a box 26 after being completely stored and folded, so as to achieve better storage. When the screen cabinet in-place transfer device is not needed, the screen cabinet in-place transfer device can be better transported.

[0051] The working process of the present invention is as follows: The distance between the two legs 4 is adjusted to suit the size of the cabinet 1 to be moved.

[0052] The cabinet body 1 is provided with a plurality of lifting rings 2, through which a horizontal stick 3 is inserted, and the horizontal stick 3 is placed on the anti-slip layer 16 of the cantilever 5, and the linear drive member 13 is operated to raise the two cantilevers 5 until the lower end surface of the cabinet body 1 is separated from the ground, and then the equipment can be pulled to the planned position, wherein the limit member 6 on the cantilever 5 can prevent the horizontal stick 3 from sliding off the cantilever 5.

[0053] After the cabinet 1 is moved, the lifting column unit 23 can be lowered first, and then the two cantilevers 5 can be folded on the connecting seat 14, and then the column 11 can be rotated around the first rotation axis, and the column 11 can be laid flat and locked by the spring pin 22. Finally, the distance between the two legs 4 can be reduced, and the two legs 4 can be brought closer to each other, and then the two legs 4 can be locked by the bolt 17. The connecting seat 14 can be removed from the moving column 12 and placed on the equipment to further reduce the size of the occupied space. Through the above process, the storage and folding of the equipment can be completed, and the size of the occupied space can be reduced.
