Description

Self-lifting cabinet and moving system thereof

Technical Field

The invention relates to an electrical device, in particular to a self-lifting cabinet and a moving system of the self-lifting cabinet.

Background

In industry and production, electrification equipment or network equipment and the like cannot be separated from a control terminal. Large and small office spaces and production sites require cabinets for storing objects of computers and related control equipment, so that protection of the storage equipment can be provided, and electromagnetic interference can be shielded. The cabinet systematically solves the problems of high-density heat dissipation, large-amount cable attachment and management, high-capacity power distribution and comprehensive compatibility of rack-mounted equipment of different manufacturers in computer application, so that the data center can operate in a high-stability environment. Furthermore, the equipment is generally required to be orderly and tidily arranged, so that the equipment is convenient to maintain later.

The main body of the existing cabinet is made of cold-rolled steel plate, and as shown in fig. 1, the existing cabinet is tall and heavy as a whole due to centralized storage of a large number of devices and cables. The existing cabinet needs to be neatly and fixedly arranged on a use site so as to conveniently check or find the equipment state and problems. But this also creates several disadvantages of using cabinets in practice.

On the one hand, the number of cabinets is increasing, and in the case that the space of a site needs to be rearranged or changed to another site, the cabinets are difficult to move. Those skilled in the art will appreciate that the entire cabinet can become quite bulky once the equipment in the cabinet is assembled. In order to move, in addition to the power failure, it is necessary to disconnect the cables between the stored devices, wait until a new site is reached and then connect and adjust the cables. Moreover, the large cabinet also needs to be transported by a forklift. In case of accidents of equipment during moving, the equipment is damaged, and production, life and production operation are directly influenced.

Another aspect is that many cabinets in actual use are not perfectly aligned. After the cables are adjusted and the equipment is debugged, the cabinet moves to cause the cables to be messy. The position between adjacent cabinets, the same row or the front and rear cabinets is small. Moreover, in practice, the cabinets need to be checked and adjusted, and need to be slightly removed, but large and heavy cabinets are not easy to move. The space available for personnel to move between cabinets is very limited, and it is almost impossible for several personnel to operate simultaneously, especially when installing, significantly servicing and updating the equipment.

Then, the cabinet needs fixed position when daily use, can not use the wheel to prevent shaking when using and causing adverse effect to equipment work. In some experimental sites, if equipment is arranged at the back row, the number of workers and the observation and guidance of some experts are more limited, the equipment is not beneficial to the test and research and development, and the utilization rate of the experimental site is reduced to a certain extent. Firstly, the maneuverability and the landing stability of the cabinet are guaranteed, and the existing cabinet is difficult to fully utilize the space of a machine room in the occasions that the machine room space is narrow and small and the test site needs the cabinet to move at any time.

With the centralization and large-scale of equipment, the situation that a plurality of people work is more and more. The more the number of the existing cabinets is increased, the more the space left for operation is reduced, and the cabinet is not suitable for the era of rapid technological development.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.

It is to be understood that the terms "a" and "an" are to be interpreted as meaning "at least one" or "one or more," i.e., that a single element may be present in a single embodiment, while in other embodiments the element may be present in a plurality, and the terms "a" and "an" are not to be interpreted as limiting the number.

The invention provides a self-lifting cabinet and a moving system thereof, which are suitable for a machine room in which a site needs to be arranged, and can provide movable space for operators in a required condition. As shown in fig. 2 to 14, the self-lifting cabinet is adapted to be movably placed on the ground, and includes a cabinet main body 10 and a lifting/lowering foot stand 20, wherein the lifting/lowering foot stand 20 is fixed to the bottom of the cabinet main body 10, and wherein the lifting/lowering foot stand 20 is deformable to lift the distance between the cabinet main body 10 and the ground to a predetermined height. In the preferred embodiment, the cabinet main body 10 can be raised to a height h from the ground by the lifting/lowering stand 20, as shown in fig. 2. When the cabinet main body 10 is lifted by a height h, the cabinet main body 10 may be moved. When the cabinet body 10 is dropped on the ground, the cabinet body 10 is stably placed and is not movable.

It should be noted that, in a case where the cabinet main body 10 is stably placed on the ground, the lifting/lowering stand 20 is retracted. When the cabinet main body 10 is lifted and ready to move, the foot raising and lowering frame 20 is stably supported on the ground. That is, the self-lifting cabinet is always placed on the ground, and the height of the cabinet body 10 can be adjusted. In the case where the cabinet main body 10 is lifted, the self-lifting cabinet can be moved with a tool from the bottom of the cabinet main body 10. For example, from the bottom of the cabinet body 10, the entire self-lifting cabinet is moved by a human power or the entire self-lifting cabinet is moved by a forklift.

In the process of deformation of the lifting/lowering foot rest 20, the cabinet main body 10 does not incline. In other words, the cabinet body 10 is kept stable during the lifting and dropping. In the preferred embodiment, the cabinet body 10 can store electronic and electrical equipment therein. In the deformation process of the self-lifting cabinet, no matter the self-lifting cabinet is lifted or dropped, the cabinet main body 10 can keep free of shaking, so that the devices stored inside cannot collide with each other or fall out, and the devices are prevented from being damaged. By utilizing the self-lifting cabinet, the stored equipment does not need to be taken out in advance before moving, and the operation steps are simplified.

It should be noted that the cabinet body 10 of the self-lifting cabinet is lifted or lowered only under the condition that the lifting/lowering foot stand 20 is triggered by operation, and dynamic change occurs. In the preferred embodiment, the cabinet main body 10 can still stably stand on the ground in a state where the lifting/lowering stand 20 lifts the cabinet main body 10. Under the condition of daily use, the self-lifting cabinet can be kept stable and still, and no adverse effect is caused on normal use. Moreover, the deformation triggering of the lifting foot rest 20 does not need hydraulic tools, so that the self-lifting cabinet can be lifted by a certain height, and the subsequent moving operation is convenient. And the inspection of a hydraulic system is also omitted, and the cost of the self-lifting cabinet is reduced.

More, the cabinet main body 10 includes a surrounding frame 11, wherein the surrounding frame 11 is disposed at the bottom, and the surrounding frame 11 surrounds and forms a cavity 12 at the bottom of the cabinet main body 10. The foot raising and lowering stand 20 is disposed in the cavity 12. When the cabinet main body 10 is placed on the ground through the enclosure 11, the self-lifting cabinet is in a state after being lifted, that is, the cabinet main body 10 directly contacts the ground. When the cabinet main body 10 is placed on the ground by the lifting/lowering foot rest 20, the self-lifting cabinet is in a lifted state, that is, the enclosure frame 11 of the cabinet main body 10 is separated from the ground.

The enclosure 11 is in the preferred embodiment a square wall that extends integrally to the bottom. In other embodiments, the enclosure 11 may be a plurality of supporting walls or supporting columns.

The lifting foot rest 20 is fixed in the cavity 12, and can increase the distance between the cavity 12 and the ground through deformation. It should be noted that the deformation of the lifting foot rest 20 increases or decreases the height of the whole self-lifting cabinet, and does not occupy the space around the self-lifting cabinet. Under the condition of daily use, the lifting foot rest 20 is also arranged in the accommodating cavity 12, and does not occupy the space outside the surrounding frame 11 of the self-lifting cabinet, so that a worker can use the space around the self-lifting cabinet to move.

Specifically, as shown in fig. 3 and 4, the lifting/lowering stand 20 includes at least two rotation leg rods 21, a driving linkage 22 and a stop assembly 23, wherein the rotation leg rods 21 are rotatably disposed at the bottom of the cabinet main body 10, wherein the driving linkage 22 is operated from the outside of the enclosure frame 11 to control the rotation state of the rotation leg rods 21, and wherein the stop assembly 23 is fixed at the bottom of the cabinet main body 10 to limit the rotation angle of the rotation leg rods 21. The rotation leg bar 21 is restricted by the stopper assembly 23 to rotate from extending along the bottom of the cabinet main body 10 to vertically extending along the bottom of the cabinet main body 10 during operation by the driving linkage 22. It is worth mentioning that the length of the turning leg rod 21 is greater than the height of the enclosure 11. That is, when the rotation leg lever 21 is rotated to extend along the enclosure 11, the enclosure 11 has been separated from the ground, and the cabinet main body 10 is supported on the ground by the rotation leg lever 21.

When the rotation leg 21 extends along the bottom of the cabinet main body 10, the lifting/lowering stand 20 is in a retracted state, and the self-lifting/lowering cabinet is supported on the ground by the enclosure 11. That is, the cabinet body 10 is directly placed on the ground. When the rotation leg rod 21 vertically extends along the bottom of the cabinet main body 10, the lifting foot stand 20 is in an open state, and the self-lifting cabinet is supported on the ground by the rotation leg rod 21. That is, the cabinet body 10 is indirectly supported by the lifting/lowering stand 20 and placed on the ground. The self-lifting cabinet is supported by the rotating leg bar 21, and the cabinet main body 10 is lifted to a certain height, so that the self-lifting cabinet can be carried at the bottom of the cabinet main body 10.

More specifically, the driving linkage 22 includes a first driving crossbar 221, at least two second driving crossbars 222 and at least two cross-shaft connectors 223, wherein the first driving crossbar 221 extends from the bottom of the cabinet body 10 to the outside of the enclosure frame 11, and the second driving crossbars 222 and the first driving crossbar 221 are vertically connected through the cross-shaft connectors 223. The second driving vertical bar 222 is connected to the leg shaft 21. The first driving crossbar 221 is triggered to drive the second vertical bar 222 to move, and the second driving vertical bar 222 moves to trigger the rotation of the leg bar 21. That is, after the first driving crossbar 221 is triggered, the rotation of the leg bar 21 is finally obtained through the cross coupling 223 and the second driving crossbar 222. The retraction and the expansion of the rotating leg rod 21 are both realized by the triggering of the first driving cross rod 221. The first driving cross bar 221 can be operated from the outside of the enclosure frame 11, and the operation of directly operating the rotating leg rod 21 is not needed, thereby facilitating the deformation operation of the lifting/lowering foot frame 20.

In the preferred embodiment, the first driving crossbar 221 is a wire lever, and when the first driving crossbar 221 is rotated along its own axis, the second driving crossbar 222 is horizontally moved by the cross shaft coupler 223. The horizontal movement of the second driving vertical bar pushes the rotation of the rotation leg bar 21. The leg lever 21 is shifted between extending along the bottom of the cabinet main body 10 and vertically extending along the bottom of the cabinet main body 10 according to different rotation directions of the first driving lever 221.

The stop assembly 23 includes at least two lifting stop blocks 231 and at least two descending stop blocks 232, wherein the lifting stop blocks 231 and the descending stop blocks 232 extend from the bottom of the cabinet body 10 respectively. The lift stopper 231 extends vertically along the bottom of the cabinet main body 10. The drop stop block 232 extends along the bottom of the cabinet body 10. During the rotation of the leg shaft 21, the position of the leg shaft 21 is intercepted, and the rotation thereof is stopped to position the position thereof with respect to the ground. The falling stopper 232 intercepts the rotation leg rod 21 and continues to rotate toward the bottom of the cabinet main body 10, so that the bottom is prevented from being damaged by friction. The lifting stopper 231 intercepts the rotation of the rotation leg lever 21 so as to be driven to rotate excessively without lifting up the cabinet main body 10.

In a preferred embodiment of the present invention, the elevation stop block 231 and the descent stop block 232 are disposed in a perpendicular manner to each other. In another possible embodiment, the lifting stop block 231 and the lowering stop block 232 are arranged at an obtuse angle to each other. That is, the lift stopper 231 extends from the cabinet body 10 in a splayed shape.

It is understood that in a preferred example of the present invention, the two second longitudinal driving levers 222 are identical in structure, and only differ from each other on two sides of the cabinet main body 10. In addition, since the two second driving vertical bars 222 are connected to the first driving crossbar 221 in the same manner, the modified relationship of the lifting/lowering stand 20 can be described by taking an example in which one of the two second driving vertical bars 222 is provided on the first driving crossbar 221 and the leg bar 21.

In the preferred embodiment, one of the second driving vertical rods 222 connects two adjacent turning leg rods 21. In other possible manners, the second longitudinal driving levers 222 may be connected to the leg rotating levers 21 in a one-to-one correspondence and respectively drive the leg rotating levers 21 to rotate.

The deformation process of the lifting/lowering foot rest 20 is shown in fig. 5 and 6. The lifting process of the self-lifting cabinet of the preferred embodiment is shown in fig. 5. First, the first driving rail 221 is triggered to rotate. In the preferred embodiment, a handle 210 is used to communicate the first driving cross bar 221 from the outside of the frame 11 to operate the rotation of the first driving cross bar 221. Due to the perpendicular arrangement of the cross shaft coupler 223 with the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the clockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the counterclockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 5, the second driving vertical bar 222 is driven to move outward by the rotation of the first driving horizontal bar 221. The outward movement of the second driving vertical bar 222 causes the connected leg bar 21 to rotate in an expanding manner. That is, the corresponding turning leg lever 21 is turned by extending it vertically along the bottom of the cabinet main body 10 depending on the turning of the turning leg lever 21 which is pushed by the second driving vertical lever 222. When the rotating leg bar 21 rotates to the position of the lift stopper 231, the rotating leg bar 21 is supported by the lift stopper 231 and cannot rotate any further. It is worth mentioning that all the turning leg bars 21 will be driven simultaneously by the turning of the first driving beam 221. The same rotation of the leg rods 21 is simultaneously performed so that the cabinet main body 10 is supported identically without being inclined in the deformation of the foot raising and lowering frame 20. Finally, the rotating leg lever 21 is driven to be opened, and the height of the cabinet main body 10 is also raised by the rotating leg lever 21. Further, the movement of the self-lifting cabinet can be completed by carrying the bottom of the cabinet main body 10.

After the self-lifting cabinet is moved to a designated position, the cabinet main body 10 can be selectively lowered to stably fix the self-lifting cabinet.

The falling process of the self-lifting cabinet of the preferred embodiment is shown in fig. 6. First, the first driving rail 221 is triggered to rotate. In the preferred embodiment, the handle 210 is used to communicate the first driving cross bar 221 from the outside of the leg unit 11 to operate the rotation of the first driving cross bar 221. It is worth mentioning that the rotation here is in the opposite direction to the rotation of fig. 5. Due to the perpendicular arrangement of the cross shaft coupler 223 and the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the counterclockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the clockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 6, the second driving crossbar 222 is driven to move inward by the rotation of the first driving crossbar 221. The inward movement of the second driving vertical bar 222 causes the connected leg shaft 21 to retractably rotate. That is, the corresponding turning leg lever 21 is turned by extending along the bottom of the cabinet main body 10 depending on the turning of the turning leg lever 21 pulled by the second driving vertical lever 222. When the rotating leg bar 21 is pulled to the position of the falling stop block 232, the rotating leg bar 21 will be blocked by the falling stop block 232 and cannot rotate any more. It is worth mentioning that all of the rotation leg rods 21 will be driven simultaneously by the rotation of the first driving cross bar 221. The same rotation of the leg rods 21 is simultaneously performed so that the cabinet main body 10 is supported identically without being inclined in the deformation of the foot raising and lowering frame 20. Finally, the rotating leg 21 is driven to retract, and the height of the cabinet main body 10 is lowered by the rotating leg 21 until the enclosure 11 contacts the ground.

Another preferred embodiment of the present invention is shown in fig. 7 to 11, and unlike the above-mentioned embodiments, the lifting/lowering foot stand 20 is provided with at least two wheels 30. The wheel 30 is provided corresponding to the rotating leg lever 21 so that the rotating leg lever 21 does not directly contact the ground but contacts the ground by the wheel 30. It should be noted that the diameter of the wheels 30 is smaller than the height of the enclosure 11. When the foot raising and lowering stand 20 is retracted, the wheels 30 are completely received in the receiving cavity 12 and supported on the ground by the surrounding frame 11. That is to say, after the self-lifting cabinet falls, the position of the self-lifting cabinet cannot move due to the wheels 30, and the stored equipment is prevented from being damaged by shaking.

Preferably, four of the wheels 30 in the present preferred embodiment are respectively provided to the free ends of the turning leg bars 21. When the journaling end of the leg shaft 21 is angularly rotated, the wheel 30 is deformed between being lowered and being retracted.

Further, as shown in fig. 8, the lifting procedure of the self-lifting cabinet of the preferred embodiment is illustrated. First, the first driving rail 221 is triggered to rotate. In the preferred embodiment, the handle 210 is used to communicate with the first driving cross bar 221 from the outside of the frame 11 to operate the rotation of the first driving cross bar 221. Due to the perpendicular arrangement of the cross shaft coupler 223 and the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the clockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the counterclockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 8, the second driving vertical bar 222 is driven to move outward by the rotation of the first driving horizontal bar 221. The outward movement of the second driving vertical bar 222 causes the connected leg bar 21 to be openly rotated. The wheels 30 leave the chamber 12 and are lowered. That is, the corresponding turning leg lever 21 is turned by extending it vertically along the bottom of the cabinet main body 10 depending on the turning of the turning leg lever 21 which is pushed by the second driving vertical lever 222. When the rotating leg bar 21 rotates to the position of the lift stopper 231, the rotating leg bar 21 is supported by the lift stopper 231 and cannot rotate any further. The wheels 30 are supported on the ground and can roll on the ground for movement. It is worth mentioning that all the turning leg bars 21 will be driven simultaneously by the turning of the first driving beam 221. The same rotation of the leg shafts 21 occurs simultaneously, and all the wheels 30 are lowered simultaneously, so that the cabinet main body 10 is supported equally without being inclined in the deformation of the foot raising and lowering frame 20. It should be noted that the free end of each of the turning leg bars 21 is preferably provided with the wheel 30. If the wheels 30 are partially provided, it is necessary to design the leg shafts 21 with different lengths so that the support height of the foot stand 20 at each angle is maintained stable in the lowered state. Finally, the leg shaft 21 is driven to be opened, the wheels 30 are lowered, and the height of the cabinet main body 10 is also raised by the leg shaft 21. Further, by pushing the cabinet body 10, the movement of the self-lifting cabinet can be completed by means of the rolling of the wheels 30.

As shown in fig. 11, after the self-lifting cabinet is moved to a predetermined position by the wheels 30, the cabinet body 10 may be selectively lowered to stably fix the self-lifting cabinet. Preferably, the wheels 30 are of the cardan shaft type. More preferably, the handle 210 is stored in the cabinet body 10 in a non-driving state, and is taken out of the cabinet body 10 when driving needs to be triggered. That is to say, the peripheral space of the self-lifting cabinet is saved when the self-lifting cabinet is stably fixed, so that the self-lifting cabinet is convenient for the operation and the activity of workers.

The falling process of the self-lifting cabinet of the preferred embodiment is shown in fig. 9. First, the first driving rail 221 is triggered to rotate. In the preferred embodiment, the handle 210 is used to communicate the first driving cross bar 221 from the outside of the leg unit 11 to operate the rotation of the first driving cross bar 221. It is worth mentioning that the rotation here is in the opposite direction to the rotation of fig. 8. Due to the perpendicular arrangement of the cross shaft coupler 223 and the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the counterclockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the clockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 9, the second driving crossbar 222 is driven to move inward by the rotation of the first driving crossbar 221. The inward movement of the second driving side rail 222 causes the connected leg bar 21 to retractably rotate, so that the wheel 30 is driven to retract into the housing 12. That is, the corresponding turning leg lever 21 is turned toward the extension along the bottom of the cabinet main body 10, and the wheels 30 are gradually slightly rolled to fit the adduction of the turning leg lever 21 depending on the turning of the turning leg lever 21 pulled by the second driving vertical lever 222. When the rotating leg bar 21 is pulled to the position of the landing stop block 232, the rotating leg bar 21 will be blocked by the landing stop block 232 and cannot rotate any more, and the wheel 30 will be completely out of supporting contact with the ground. It is worth mentioning that all of the rotation leg rods 21 will be driven simultaneously by the rotation of the first driving cross bar 221. The same rotation of the leg rods 21 is simultaneously performed so that the cabinet main body 10 is supported identically without being inclined in the deformation of the foot raising and lowering frame 20. Finally, the rotating leg 21 is driven to retract, the wheel 30 is received in the receiving cavity 12, and the height of the cabinet main body 10 is also lowered by the rotating leg 21 until the enclosure 11 contacts the ground to fix the position of the self-lifting cabinet.

In particular, the wheels 30 have a different general damping effect during the descent process of the self-lifting cabinet, as shown in fig. 10. The wheel 30 is driven by the rotating leg 21 to gradually move toward the cavity 12. During the moving process, the wheels 30 not only prevent the rotation leg 21 from rubbing against the ground, and prevent the rotation leg 21 from wearing to cause the self-lifting cabinet to lose uniform support, but also the wheels 30 passively roll inwards. The inward rolling of the wheels 30 will facilitate the gradual lowering of the cabinet main body 10. Avoiding the final small angle support, the cabinet body 10 slams. The wheels 30 may assist in gradually lowering the height of the cabinet body 10 to avoid sudden floor shocks to the stored equipment.

Another possible mode of the present preferred embodiment is as shown in fig. 12 to 14. Unlike the above embodiment, the self-lifting cabinet further includes a driving motor 40, and the driving motor 40 is fixed to the surrounding frame 11 and adapted to rotate the driving linkage 22 of the lifting/lowering foot frame 20. In the preferred embodiment, the driving motor 40 is disposed outside the frame 11 and is coupled to the first driving rail 221 of the driving linkage 22. It will be understood by those skilled in the art that the driving motor 40 may be disposed inside the enclosure 11, i.e. inside the cavity 12, to save the peripheral space of the self-lifting cabinet.

As shown in fig. 12, first, the first driving cross bar 221 is triggered to rotate. In the preferred embodiment, the driving motor 40 is used to communicate the first driving cross bar 221 from the outside of the frame 11 to operate the rotation of the first driving cross bar 221. Due to the perpendicular arrangement of the cross shaft coupler 223 and the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the clockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the counterclockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 12, the second driving vertical bar 222 is driven to move outward by the rotation of the first driving horizontal bar 221. The outward movement of the second driving vertical bar 222 causes the connected leg bar 21 to rotate in an expanding manner. The wheel 30 leaves the chamber 12 and is lowered. That is, the corresponding turning leg lever 21 is turned by extending it vertically along the bottom of the cabinet main body 10 depending on the turning of the turning leg lever 21 pushed by the second driving lever 222. When the rotation leg rod 21 rotates to the position of the lift stop block 231, the rotation leg rod 21 is supported by the lift stop block 231 and cannot rotate any further. At this time, the driving motor 40 is controlled to stop rotating. The wheels 30 are supported on the ground and can roll on the ground for movement. It is worth mentioning that all the turning leg bars 21 will be driven simultaneously by the turning of the first driving beam 221. The same rotation of the leg shafts 21 occurs simultaneously, and all the wheels 30 are lowered simultaneously, so that the cabinet main body 10 is supported identically without being inclined in the deformation of the foot raising and lowering frame 20. It is noted that preferably the free end of each of the turning leg bars 21 is provided with the wheel 30. If the wheels 30 are partially provided, the leg shaft 21 of different lengths should be designed so that the support height at each angle of the foot stand 20 is maintained stable in the lowered state. Finally, the leg shaft 21 is driven to be opened, the wheels 30 are lowered, and the height of the cabinet main body 10 is also raised by the leg shaft 21. Further, by pushing the cabinet body 10, the movement of the self-lifting cabinet can be completed by means of the rolling of the wheels 30. It is worth mentioning that the timing at which the driving motor 40 is stopped needs to be controlled according to the timing at which the leg lever 21 reaches the lift stopper 231.

The falling process of the self-lifting cabinet of the preferred embodiment is shown in fig. 13. First, the first driving rail 221 is triggered to rotate. In the preferred embodiment, the driving motor 40 is used to communicate the first driving cross bar 221 from the outside of the frame 11 to operate the rotation of the first driving cross bar 221. It is worth mentioning that the rotation here is in the opposite direction to that of fig. 12. Due to the perpendicular arrangement of the cross shaft coupler 223 and the first driving crossbar 221 and the second driving crossbar 222, the rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move inwards or outwards. For example, the counterclockwise rotation of the first driving crossbar 221 will drive the second driving crossbar 222 to move towards the outside of the cavity 12, and the clockwise rotation of the second driving crossbar 222 will drive the second driving crossbar 222 to move towards the inside of the cavity 12. As shown in fig. 12, the second driving crossbar 222 is driven to move inward by the rotation of the first driving crossbar 221. The inward movement of the second driving side rail 222 causes the connected leg shaft 21 to retractably rotate, so that the wheel 30 is driven to retract into the housing 12. That is, the corresponding turning leg lever 21 is turned toward the extension along the bottom of the cabinet main body 10, and the wheels 30 are gradually slightly rolled to fit the adduction of the turning leg lever 21 depending on the turning of the turning leg lever 21 pulled by the second driving vertical lever 222. When the rotating leg bar 21 is pulled to the position of the landing stop block 232, the rotating leg bar 21 will be blocked by the landing stop block 232 and cannot rotate any more, and the wheel 30 will be completely out of supporting contact with the ground. It is worth mentioning that all the turning leg bars 21 will be driven simultaneously by the turning of the first driving beam 221. The same rotation of the leg rods 21 is simultaneously performed so that the cabinet main body 10 is equally supported without being inclined in the deformation of the foot raising and lowering frame 20. Finally, the rotating leg 21 is driven to retract, the wheel 30 is received in the receiving cavity 12, and the height of the cabinet main body 10 is also lowered by the rotating leg 21 until the enclosure 11 contacts the ground to fix the position of the self-lifting cabinet. It is worth mentioning that the timing at which the driving motor 40 is stopped is controlled according to the timing at which the leg shaft 21 reaches the falling stopper 232.

In another possible solution, it is preferable that the self-lifting cabinet further comprises at least one moving motor, wherein the moving motor is disposed on the wheel 30 to drive the wheel 30 to roll in a predetermined direction.

Further, as shown in fig. 14, the self-elevating cabinet further includes a controller 50, and the controller 50 is communicably connected to the driving motor 40. That is, the driving motor 40 is turned on to be rotated or is turned off to be stopped by the setting of the controller 50.

Preferably, the controller 50 further controls the moving motor such that the moving motor is controlled to rotate or stop. Therefore, the worker can remotely control the lifting, falling and moving distance and direction of the self-lifting cabinet, and the mobility in the machine room is greatly facilitated.

More preferably, the controller 50 further carries a self-lifting cabinet moving system, and the lifting foot stand 20 and the driving motor 40 are individually operated to move the cabinet body 10. The self-lifting cabinet moving system can further control the moving motor to set the moving distance and direction of the cabinet main body 10.
