[0002] Nowadays, more and more data centers are single-row, double-row, and modular clustered. Regardless of the size of the application scenario, they are basically composed of basic cabinet units. With the increase in the number of cabinets and the improvement in the power density of a single cabinet, the weight of a single cabinet gradually increases. The difficulty of merging cabinets and moving cabinets between cabinets still uses the traditional manual merging method, which will increase and require a long time to merge cabinets. There is also a method in the prior art to set universal wheels at the bottom of the cabinet to facilitate the pushing of the cabinet, but the cabinet often needs to be fixed after it is moved to the specified position, and the setting of universal wheels is not conducive to the stability of the cabinet.

[0015] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In technical solution 1, when the second object is connected to the outside of the first object, the pushing member is operated to make the pushing member move along the first direction relative to the second object. At this time, the pushing member mainly drives the pushing part to approach the limiting part, and the pushing part presses the limiting part and makes the limiting part retract into the plug-in part, so that the plug-in part of the plug-in part can be extended into the first object through the plug-in hole, and then the pushing member is operated to make the pushing member drive the pushing part away from the limiting part, and the elastic part is not subjected to external force. It should be understood that the external force here is mainly the force artificially applied to the pushing member and then to the elastic part. The limiting part at least partially extends out of the through hole and abuts against the inner surface of the connecting wall. Since the plug-in part is adapted to the plug-in hole, the first object and the second object limit each other along any direction perpendicular to the first direction. Since the limiting part is stably parked at the first position relative to the plug-in part, the limiting part abuts against the inner surface of the connecting wall. When the first object and the second object are in contact with each other, the outer surfaces of the first object and the second object are abutted against each other, and the first object and the second object are limited along the first direction, and the second object is connected to the outside of the first object; when the second object needs to be removed, the pushing member is operated to make the pushing member move relative to the second object along the first direction, and at this time, the pushing member drives the pushing part to approach the limiting part, and the pushing part presses the limiting part and makes the limiting part retract into the plug-in part, pulling the second object outward, and the plug-in part gradually withdraws from the plug-in hole, and the second object is gradually separated from the first object; it can be seen that by adopting the present technical solution, the connection or disassembly of the first object and the second object is relatively convenient, and the structure is simple. In actual use, the first object and the second object can be connected or separated as needed, which can meet a variety of usage scenarios; in addition, it is only necessary to open a plug-in hole in the first object along the first direction, and the modification of the first object is small.

[0017] 2. In the second technical solution, an elastic reset member is provided, and the elastic reset member is deformed when the pushing portion presses against the limiting portion, that is, the elastic reset member stores energy when the pushing portion is close to the limiting portion. Therefore, when force is no longer applied to the pushing member, the elastic reset member can release energy to drive the pushing portion away from the limiting portion, further making the connection operation between the first object and the second object simpler and more labor-saving.

[0018] 3. In technical solution three, an operating part is provided on the pushing member, and the pushing part forms an inclined surface cooperation with the elastic part only when the operating part is pushed into the second object, that is, when the elastic part is not subjected to external force, the limiting part is also not subjected to other forces, which is conducive to driving the limiting part to at least partially extend out of the through hole when the elastic part is not subjected to external force, thereby making the connection structure between the first object and the second object more stable.

[0019] 4. In technical solution four, the limiting part is provided with a mating surface and a limiting protrusion. When the limiting part is located at the first position, the limiting protrusion extends out of the through hole, and the mating surface abuts against the inner surface of the plug-in wall. Since the limiting protrusion protrudes from the mating surface, that is, the limiting protrusion is basically perpendicular to the first direction when the limiting part is parked at the first position, the structure of the limiting protrusion is more stable and not easy to shake, thereby ensuring a stable connection between the first object and the second object; the pushing part is provided with a pointed end. When the pushing part is pushed toward the limiting part, the pointed end is inserted between the mating surface and the inner surface of the plug-in wall, and the pointed end presses against the mating surface. The inclined surface of the pointed end is at least partially located between the mating surface and the inner surface of the plug-in wall. The free end of the limiting part gradually moves away from the inner surface of the plug-in wall, and the limiting protrusion gradually retracts into the connector. The structure is ingenious and stable.

[0020] 5. In technical solution five, the elastic limiting member includes an elastic sheet and a limiting block fixed to the elastic sheet. The end of the elastic sheet away from the pushing member is fixed to the plug-in wall. The part of the elastic sheet close to its fixed end forms the elastic part of the elastic limiting member. The limiting block forms a limiting protrusion. The structure is simple and practical. The connecting wall forms the cavity wall of the accommodating cavity. The pushing portion is located in the accommodating cavity, which prevents the limiting portion or the pushing portion from contacting components in the first object during movement.

[0021] 6. In technical solution six, the elastic limiter includes a C-shaped elastic sheet and a limiter block. The third wall of the C-shaped elastic sheet forms an elastic part of the elastic limiter near the connecting part between the third wall and the fourth wall. The limiter block is fixed to the third wall and forms a limiter protrusion. The structure of the C-shaped elastic sheet is such that when the elastic part is not subject to force, the mating surface abuts against the inner surface of the plug-in wall and the limiter protrusion extends out of the through hole, and the structure is stable, thereby ensuring a stable connection between the first object and the second object; the plug-in wall forms the cavity wall of the accommodating cavity, and the pushing part is located in the accommodating cavity, thereby preventing the limiting part or the pushing part from contacting components in the first object during movement.

[0022] 7. In technical solution seven, the plug-in component is provided with a first abutting surface, the pushing component is provided with a second abutting surface parallel to and opposite to the first abutting surface, the elastic reset component is sleeved on the pushing component and its two ends act on the first abutting surface and the second abutting surface, and the structure is simple and practical.

[0023] 8. In technical solution eight, the present invention also provides a moving device, including the above-mentioned connecting structure. When the first object needs to be moved, the second object is connected to the first object as described above. Since each connecting wall is provided with at least one plug hole group, the second objects are connected to the opposite sides of the cabinet. The number of moving structures is equal to the number of second objects, that is, universal wheels are arranged on the opposite sides of the cabinet, and each driving member drives the corresponding universal wheel to extend downward out of the second object. The cabinet is suspended relative to the ground, which can push the cabinet to move; when the cabinet moves to the desired position, each driving member drives the corresponding universal wheel to retract upward into the second object, and the cabinet is supported by the ground, and then the second object and the first object can be disassembled as described above; it can be seen that by adopting this technical solution, the second object can be installed on both sides of the cabinet as needed, thereby facilitating the movement of the cabinet, and when the cabinet does not need to be moved, the cabinet is fixed relative to the ground, which is more stable and can meet a variety of usage scenarios.

[0024] 9. In technical solution nine, the plug hole group includes at least three plug holes, at least one of which is located outside the straight line where the other two plug holes are located, that is, the plug hole group has at least three plug holes that can form a triangle. The triangular structure is more stable, so that when the second object is connected to the first object, at least three connection points that can form a triangle are formed, thereby making the connection between the first object and the second object more stable.

[0025] 10. In technical solution 10, the provision of the sealing gasket prevents impurities from entering the first object through the plug-in hole, and also forms a buffer when the second object approaches the first object, thereby preventing the components in the cabinet from being damaged by vibration; the moving structure also includes a guide member and a fixed plate, the guide member is fixedly connected to the universal wheel and is suitable for abutting the upper surface of the fixed plate to limit the downward movement of the universal wheel, ensuring that the universal wheels are at the same height when extending downward from the second object, thereby facilitating the movement of the cabinet; the number of connecting walls is two, the number of plug-in hole groups is four, and the four plug-in hole groups are respectively close to the four vertex corners of the first object, that is, there is a universal wheel at each of the four vertex corners of the cabinet, which saves more effort when the cabinet is moved.

[0043] Example 1

[0044] See also Figure 1-5 , Figure 1-5 A connection structure is shown, which is used to connect a second object 200 to a first object 100. The first object 100 is provided with a connection wall 101, and the connection wall 101 is provided with a plug hole 1011 along a first direction. Figure 1 The middle connecting wall 101 extends in a vertical direction, and the first direction is a left-right direction.

[0045] See also Figure 2-5 The connecting structure includes a plug-in component 10, an elastic limiting component 20, a pushing component 30 and an elastic reset component 40.

[0046] The connector 10 is fixedly connected to the second object 200 and is provided with a connector portion protruding along the first direction relative to the second object 200 and adapted to the connector hole 1011; the connector portion is suitable for passing through the connector hole 1011 along the first direction and extending into the first object 100, and is provided with a through hole 111 along a direction perpendicular to the first direction; in this embodiment, the second object 200 is provided with an abutment wall 201 parallel to and opposite to the connecting wall 101, and the connector portion protrudes from the abutment wall 201.

[0047] The plug connector 10 is provided with a plug wall 11 parallel to the first direction, and the through hole 111 is provided on the plug wall 11. In a specific implementation, the plug connector 10 extends along the first direction and is in a rectangular parallelepiped shape, wherein a rectangular parallelepiped accommodating cavity 01 is formed, and the plug wall 11 forms the cavity wall of the accommodating cavity 01. The plug connector 10 is further provided with a first wall 12 and a second wall 13 forming the cavity wall of the accommodating cavity 01. The connecting wall 101, the first wall 12 and the second wall 13 are connected in sequence, the first wall 12 is perpendicular to the first direction, and the second wall 13 is parallel to the connecting wall 101.

[0048] The elastic limiting member 20 is provided with an elastic portion 21 and a limiting portion 22 which are mounted in the connector 10. The elastic portion 21 is configured to drive the limiting portion 22 to stop at a first position when no external force is applied. In the first position, the limiting portion 22 at least partially extends out of the through hole 111 and is suitable for abutting against the inner surface of the connecting wall 101.

[0049] One end of the pusher 30 extends into the connector 10 along the first direction and is provided with a pusher 31 suitable for forming an inclined surface with the limiting portion 22. The pusher 31 is located in the accommodating cavity 01. When the pusher 30 is operated to move relative to the second object 200 along the first direction, the pusher 31 is suitable for pressing the limiting portion 22 to retract the limiting portion 22 into the connector 10. In a specific implementation, the other end of the pusher 30 extends out of the second object 200 and is provided with an operating portion 32. The pusher 31 forms an inclined surface with the limiting portion 22 only when the operating portion 32 is pushed into the second object 200. The operating portion 32 is used for the user to operate and apply force. In this embodiment, the pusher 30 extends along the first direction and can move relative to the connector 10 and the second object 200 along the first direction.

[0050] The elastic reset member 40 extends along the first direction, and the two ends of the elastic reset member 40 act on the push member 30 and the plug-in connector 10 respectively. The elastic reset member 40 is configured to deform when the push portion 31 presses against the limit portion 22. Specifically, one end of the plug-in connector 10 away from the plug-in portion is embedded in the second object 200 and is provided with a first abutting surface 14 perpendicular to the first direction. The push member 30 is also provided with a second abutting surface 33 parallel to and opposite to the first abutting surface 14. The elastic reset member 40 is sleeved on the push member 30 and the two ends act on the first abutting surface 14 and the second abutting surface 33. The elastic reset member 40 is a reset spring in this embodiment.

[0051] In this embodiment, the limiting portion 22 is provided with a mating surface 221 perpendicular to the first direction and a limiting protrusion 222 protruding from the mating surface 221, and the end of the limiting portion 22 close to the pushing member 30 forms a free end; in the first position, the mating surface 221 abuts against the inner surface of the plug-in wall 11, and the limiting protrusion 222 extends out of the through hole 111 and is suitable for abutting against the inner surface of the connecting wall 101; the pushing portion 31 is wedge-shaped, and is provided with a tip 311 suitable for inserting between the mating surface 221 and the plug-in wall 11 toward the limiting portion 22, and the tip 31 1 is provided with an inclined surface inclined with respect to the first direction with respect to the mating surface 221. In this embodiment, the inclined surface is inclined from top to bottom toward the outside of the first object 100. When the operating portion 32 is pushed into the second object 200, the tip 311 presses against the mating surface 221. The inclined surface is at least partially located between the mating surface 221 and the inner surface of the plug-in wall 11 to retract the limiting protrusion 222 into the plug-in connector 10, so that the pushing portion 31 forms an inclined surface match with the elastic portion 21 only when the operating portion 32 is pushed into the second object 200. It can be seen that the limiting protrusion 222 is substantially perpendicular to the first direction when the limiting portion 22 is parked at the first position. The structure of the limiting protrusion 222 is more stable and not easy to shake, thereby ensuring a stable connection between the first object 100 and the second object 200.

[0052] The elastic limiting member 20 has the following embodiments:

[0053] Implementation method 1: See Figure 2-3 The elastic limiting member 20 includes an elastic sheet parallel to the first direction and a limiting block fixed to the elastic sheet. One end of the elastic sheet away from the pushing member 30 is fixed to the plug-in wall 11. In this embodiment, one end of the elastic sheet away from the pushing member 30 is welded to the plug-in wall 11. The portion of the elastic sheet close to its fixed end forms the elastic portion 21 of the elastic limiting member 20, and the limiting block forms a limiting protrusion 222. The portion of the elastic sheet other than the fixed end and the elastic portion 21 cooperates with the limiting block to form the limiting portion 22. This structure is simple and practical, and ensures that the limiting protrusion 222 is stably docked at the first position, thereby ensuring a stable connection between the first object 100 and the second object 200.

[0054] Implementation method 2: See Figure 4-5The elastic stopper 20 includes a C-shaped elastic sheet and a stopper block. The C-shaped elastic sheet is provided with a third wall 23, a fourth wall 24 and a fifth wall 25 connected in sequence. The stopper block is fixed to the third wall 23 and forms a stopper protrusion 222. The opening of the C-shaped elastic sheet faces the pusher 30. The fourth wall 24 and the fifth wall 25 are respectively fixed to the first wall 12 and the second wall 13. The third wall 23 near the connection part with the fourth wall 24 forms the elastic part 21 of the elastic stopper 20. In this embodiment, the fourth wall 24 and the fifth wall 25 are respectively welded to the first wall 12 and the second wall 13. The part of the third wall 23 other than the elastic part 21 cooperates with the stopper protrusion 222 to form the stopper 22. This structure is simple and practical, and ensures that the stopper protrusion 222 is stably parked at the first position, thereby ensuring the stable connection between the first object 100 and the second object 200.

[0055] Of course, in other embodiments, the elastic part may also be a torsion spring, one end of which is connected to the plug-in wall and the other end is connected to the limiter, or the elastic part may be a spring extending in the vertical direction and the limiter is fixed to the top of the spring, which will not be described in detail in this embodiment.

[0056] The usage process is as follows:

[0057] When the second object 200 is connected to the outside of the first object 100, the operating portion 32 is pushed into the second object 200 along the first direction, and the pushing member 30 drives the pushing portion 31 to approach the limiting portion 22. At this time, the elastic reset member 40 is compressed to store energy, and the tip 311 of the pushing portion 31 is inserted between the matching surface 221 and the inner surface of the plug-in wall 11 and presses the matching surface 221, thereby driving the limiting protrusion 222 to gradually retract into the plug-in component 10. At this time, the elastic portion 21 of the elastic limiting member 20 is deformed and stores energy, and the plug-in portion of the plug-in component 10 can be extended into the first object 100 through the plug-in hole 1011 until the outer surface of the abutting wall 201 abuts against the inner surface of the connecting wall 101;

[0058] Then, the operating part 32 is released, and the pushing member 30 moves away from the first object 100 along the first direction under the action of the elastic reset member 40, and the operating part 32 moves outward of the second object 200 along the first direction, and the tip 311 of the pushing part 31 no longer presses the mating surface 221, and the elastic part 21 of the elastic limiting member 20 releases energy to drive the limiting protrusion 222 to extend out of the through hole 111 and drive the mating surface 221 to abut against the inner surface of the plug-in wall 11, and the limiting protrusion 222 can abut against the inner surface of the connecting wall 101 At this time, since the plug-in portion is matched with the plug-in hole 1011, the first object 100 and the second object 200 are limited to each other along any direction perpendicular to the first direction. Since the limiting portion 22 is stably parked at the first position relative to the plug-in portion, the limiting portion 22 abuts against the inner surface of the connecting wall 101, and the outer surface of the abutting wall 201 abuts against the outer surface of the connecting wall 101. The first object 100 and the second object 200 are limited along the first direction, and the second object 200 is connected to the outside of the first object 100.

[0059] When the second object 200 needs to be disassembled, the operating part 32 is pushed into the second object 200 along the first direction, and the pushing member 30 drives the pushing part 31 to approach the limiting part 22. At this time, the elastic reset member 40 is compressed to store energy, and the tip 311 of the pushing part 31 is inserted between the mating surface 221 and the inner surface of the plug-in wall 11 and presses against the mating surface 221, thereby driving the limiting protrusion 222 to gradually retract into the connector 10, and the second object 200 is pulled outward, and the plug-in part gradually withdraws from the plug-in hole 1011, and the second object 200 is also gradually separated from the first object 100.

[0060] It can be seen that by adopting the present technical solution, the connection or disassembly of the first object 100 and the second object 200 is relatively convenient, which can meet a variety of usage scenarios, and the structure is simple and ingenious, and the operation is convenient; wherein, only the plug-in hole needs to be opened in the first direction in the first object 100, and the modification of the first object 100 is small; the part inserted into the first object 100 does not contact the parts in the first object 100, thereby avoiding affecting the first object 100; the pushing portion 31 forms an inclined surface with the limiting portion 22 only when the operating portion 32 is pushed into the second object 200, that is, when the elastic portion 21 is not subjected to external force, the limiting portion 22 is also not subjected to other forces. It should be understood that the external force here is mainly the force artificially applied to the pushing member 30 and then applied to the elastic portion 21, which is conducive to driving the limiting portion 22 to at least partially extend out of the through hole 111 when the elastic portion 21 is not subjected to external force, so that the connection structure between the first object 100 and the second object 200 is more stable.

[0061] Example 2

[0062] The present invention also provides a mobile device, see Figure 1-9 , including a first object 100, a second object 200, a connecting structure, a moving structure and a sealing gasket 300.

[0063] The first object 100 is a cabinet, which is provided with at least two parallel and opposite connecting walls 101, each connecting wall 101 extends in the vertical direction and is provided with at least one plug hole group, each plug hole group includes at least one plug hole 1011; in this embodiment, preferably, the plug hole group includes at least three plug holes 1011, wherein at least one plug hole 1011 is located outside the straight line where the other two plug holes 1011 are located. In this embodiment, see Figure 1 Each group of plug holes 1011 includes three plug holes 1011 that can form a right triangle.

[0064] The number of the second objects 200 is equal to the number of the plug hole groups, and they are mainly in the shape of a hollow box.

[0065] The number of the connection structures is equal to and corresponds to the number of the plug holes 1011 , which is the same as that of the first embodiment.

[0066] The number of movable structures is equal to and corresponds to the number of second objects 200. The movable structures are arranged in the second object 200 and include universal wheels 50 and driving members 60. The driving members 60 are suitable for driving the universal wheels 50 to move in the vertical direction to extend downward from the corresponding second object 200 or retract into the corresponding second object 200. When each universal wheel 50 extends downward from the second object 200, the cabinet is suspended relative to the ground. When each universal wheel 50 is retracted upward into the second object 200, the cabinet is supported by the ground. In a specific implementation, the movable structure also includes a guide member 70, a fixed plate 80 and a telescopic plate 90. The fixed plate 80 is fixed in the second object 200 and parallel to the ground. The guide member 70 passes through the fixed plate 80 and is fixedly connected to the universal wheel 50 and is suitable for abutting against the upper surface of the fixed plate 80 to limit the downward movement of the universal wheel 50. The telescopic plate 90 is located below the fixed plate 80 and is fixedly connected to the driving member 60. In this embodiment, the driving member 60 is a cylinder, the fixed end of the cylinder is fixedly connected to the inner top wall of the second object 200, the output end thereof passes through the fixed plate 80 and is fixedly connected to the upper surface of the telescopic plate 90, and the universal wheel 50 is fixedly connected to the lower surface of the telescopic plate 90; the guide member 70 is four guide rods extending in the vertical direction, the bottom ends of the four guide rods are fixedly connected to the upper surface of the telescopic plate 90, the top ends thereof pass through the fixed plate 80 and are provided with a third abutting surface 71 suitable for abutting the upper surface of the fixed plate 80, the driving member 60 drives the universal wheel 50 to extend out of the bottom end of the second object 200 by driving the telescopic plate 90 to move downward, when the third abutting surface 71 abuts against the upper surface of the fixed plate 80, the driving member 60 no longer drives the telescopic plate 90 to move downward, at this time, the universal wheel 50 extends out of the second object 200.

[0067] The number of the sealing pads 300 is equal to the number of the second objects 200, see Fig. 9The sealing gasket 300 is arranged between the connecting wall 101 and the corresponding second object 200. In actual application, the sealing gasket 300 is fixed to the abutting wall 201 of the second object 200. The setting of the sealing gasket 300 prevents impurities from entering the first object 100 from the plug-in hole, and also forms a buffer when the second object 200 approaches the first object 100, thereby preventing the components in the cabinet from being damaged by vibration.

[0068] In this embodiment, there are two connecting walls 101 and four plug-in control groups. The four plug-in hole groups are respectively close to the four vertex corners of the first object 100, that is, there is a universal wheel 50 at each of the four vertex corners of the cabinet, which saves effort when moving the cabinet.

[0069] In actual application, the four driving members 60 can be controlled by the same controller to ensure that the four universal wheels 50 are extended or retracted at the same time. This part belongs to the prior art and will not be described in detail in this embodiment.

[0070] When the first object 100 needs to be moved, the second object 200 is connected to the first object 100 as in Example 1. Since each connecting wall 101 is provided with at least one plug hole group, the second objects 200 are connected to the opposite sides of the cabinet. The number of movable structures is equal to the number of second objects 200, that is, universal wheels 50 are arranged on the opposite sides of the cabinet. The plug hole group has three plug holes 1011 that can form a triangle. The triangular structure is more stable, so that three connection points that can form a triangle are formed when the second object 200 is connected to the first object 100, thereby making the connection between the first object 100 and the second object 200 more stable; each driving member 60 drives the corresponding universal wheel 50 to extend downward from the second object 200, and the cabinet is suspended relative to the ground, so that the cabinet can be pushed to move; the guide member 70 is fixedly connected to the universal wheel 50 and is suitable for abutting the upper surface of the fixing plate 80 to limit the downward movement of the universal wheel 50, ensuring that each universal wheel 50 has the same height when extending downward from the second object 200, thereby facilitating the movement of the cabinet;

[0071] When the cabinet moves to the desired position, each driving member 60 drives the corresponding universal wheel 50 to retract upward into the second object 200, and the cabinet is supported by the ground. Subsequently, the second object 200 and the first object 100 can be disassembled as above. It can be seen that by adopting the present technical solution, the second object 200 can be installed on both sides of the cabinet as required, thereby facilitating the movement of the cabinet, and when the cabinet does not need to be moved, the cabinet is fixed relative to the ground and is more stable.

[0072] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
