[0021] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following Figure 1-7 This application is described in further detail.

[0022] The embodiment of the present invention provides a compact central cabinet that is easy to disassemble and assemble. Figure 1 and Figure 2The compact center cabinet which is easy to disassemble and assemble comprises a cabinet frame 1, a folding side panel 2, a side panel lifting drive assembly 3, a side panel pushing assembly 4 and a side panel locking assembly 5.

[0023] Reference Figure 1 and Figure 2 The folding side panels 2 and the side panel push-out assemblies 4 are symmetrically provided with two groups, and the two groups of folding side panels 2 correspond to the two groups of side panel push-out assemblies 4 one by one and are respectively located on both sides of the cabinet frame 1. The folding side panels 2 include a folding bottom panel 21, an intermediate panel 22 located above the folding bottom panel 21, and a folding top panel 23 located above the intermediate panel 22. The bottom of the folding bottom panel 21 is hingedly connected to the cabinet frame 1, the top is hingedly connected to the intermediate panel 22, and the top of the intermediate panel 22 is hingedly connected to the folding top panel 23. The side panel lifting drive assembly 3 is arranged on the top of the cabinet frame 1, and the two folding top panels 23 are connected to the side panel lifting drive assembly 3 so that the two folding side panels 2 can be automatically lifted, disassembled and installed. The side panel push-out assembly 4 is slidably arranged on the cabinet frame 1, and a control handle 11 is rotatably arranged on the cabinet frame 1. Both sets of side panel push-out assemblies 4 are connected to the control handle 11. When the control handle 11 is rotated, the two side panel push-out assemblies 4 are driven to extend out of the cabinet frame 1, and a thrust is applied to the corresponding folding bottom plate 21 near the middle plate 22, so as to drive the hinge of the folding bottom plate 21 and the middle plate 22 to rotate and bend to the side away from the cabinet frame 1. The side panel locking assembly 5 is arranged on the cabinet frame 1 and connected to the side panel push-out assembly 4 to realize linkage. When the side panel push-out assembly 4 moves outward, the side panel locking assembly 5 is suitable for being inserted into the folding side panel 2 to lock the rotation and up and down movement of the folding side panel 2; when the side panel push-out assembly 4 is retracted into the cabinet frame 1, the side panel locking assembly 5 releases the lock on the folding side panel 2.

[0024] Among them, the hinges of the folding bottom plate 21, the middle plate 22 and the folding top plate 23 are all hingedly connected by hinged connecting rods. Both sides of the bottom of the side of the cabinet frame 1 are welded with hinged ears, and the folding bottom plate 21 is located between the two hinged ears, and the folding bottom plate 21 is hingedly connected to the hinged ears through a threaded cylindrical pin. Therefore, when releasing the connection between the folding bottom plate 21 and the cabinet frame 1, it is only necessary to unscrew the threaded cylindrical pin, making it easier to disassemble the entire folding side plate 2.

[0025] Reference Figure 1 and Figure 2, a front panel 12 and a rear panel 13 are provided at the front and rear of the cabinet frame 1 respectively. One side of the front panel 12 is hingedly connected to the cabinet frame 1, and the rear panel 13 includes three independent panels, which are fixedly connected to the cabinet frame 1 by bolts. Under normal circumstances, during maintenance, it is only necessary to remove the two folding side panels 2; if the maintenance location is close to the rear panel 13, the panels at the corresponding positions of the rear panel 13 can be removed, and there is no need to remove all three panels, which improves the convenience of disassembly during maintenance. In another embodiment, the three panels of the rear panel 13 are hingedly connected to each other to form a structure similar to the folding side panel 2, and the rear panel 13 is connected to the side panel lifting drive assembly 3 and is synchronously lifted and lowered with the folding side panel 2 to achieve disassembly and installation.

[0026] Reference Figure 2 and Figure 3 Since the front panel 12 is hingedly connected to the cabinet frame 1, the control handle 11 is arranged on the side of the cabinet frame 1 close to the front panel 12. When the control handle 11 needs to be operated, the front panel 12 only needs to be rotated to open. A limit stopper 121 is fixedly arranged on the front panel 12. When the front panel 12 is in a closed state, the limit stopper 121 is suitable for being inserted into the cabinet frame 1 to limit the rotation of the control handle 11. This prevents non-professionals from accidentally touching the control handle 11 directly from the outside, and prevents the control handle 11 from rotating internally due to other factors, thereby improving the safety of the entire operation.

[0027] Reference Figure 1 and Figure 2 A rectangular top cabinet panel 14 is installed on the top of the cabinet frame 1, and a bracket plate is fixedly installed on the top of the top cabinet panel 14. The side panel lifting drive assembly 3 includes a driving motor 31, a winding drum 32 and a fixed pulley set 33. The driving motor 31 is fixedly installed on the bracket plate, and the winding drum 32 is installed on the motor shaft of the driving motor 31, and the driving motor 31 drives the winding drum 32 to rotate. Since two folding side panels 2 are provided in this embodiment, two groups of fixed pulley sets 33 are provided, and each group of fixed pulley sets 33 includes two fixed pulleys, and the four fixed pulleys are respectively fixed at four right angles on the top of the top cabinet panel 14.

[0028] A section of steel wire 34 is wound around each fixed pulley, and the steel wire 34 on the two fixed pulleys of the same group are respectively tied to the two sides of the corresponding folding top plate 23, and the other end is fixed and wound on the winding drum 32. In this way, after the folding side plate 2 is lowered, removed and folded, the steel wire 34 is located at the front and rear sides of the side of the cabinet frame 1, rather than in the middle of the side of the cabinet frame 1, so as not to have a great impact on the maintenance personnel during maintenance.

[0029] Since the steel wire rope 34 is provided with four sections, in order to prevent the four sections of steel wire rope 34 from being entangled with each other when the winding drum 32 rotates, three partition plates are spaced and fixedly provided on the winding drum 32 in the vertical direction. The four sections of steel wire rope 34 are spaced apart in the vertical direction and two adjacent sections of steel wire rope 34 are located on both sides of the corresponding partition plates.

[0030] Since the two groups of side panel push-out assemblies 4 have the same structure, the following description will be made by taking the cooperation between one group of side panel push-out assemblies 4 and one group of folding side panels 2 as an example.

[0031] Reference Figures 3 to 6 The side panel push-out assembly 4 includes a guide sleeve 41, a push block 42, a drive rod 43 and a drive hinge rod 44. The guide sleeve 41 is a rectangular shell, and the guide sleeve 41 is located on the side of the cabinet frame 1 side wall close to the front panel 12, and the guide sleeve 41 is welded to the cabinet frame 1. The push block 42 is inserted in the guide sleeve 41, and the push block 42 can move closer to or away from the folding bottom plate 21 in the guide sleeve 41. When the push block 42 is forced to protrude from the cabinet frame 1, the push block 42 will apply a thrust to the side where the folding bottom plate 21 and the middle plate 22 are hinged, so as to drive the hinge of the folding bottom plate 21 and the middle plate 22 to rotate and bend toward the side away from the cabinet frame 1. The drive rod 43 is located on the side of the push block 42 away from the folding bottom plate 21, and one end of the drive rod 43 is inserted in the guide sleeve 41 and fixedly connected to the push block 42; the other end extends in the direction close to the control handle 11. The driving hinge rod 44 is located between the driving rod 43 and the control handle 11, and the two sides of the driving hinge rod 44 are respectively hingedly connected to the driving rod 43 and the control handle 11. After the maintenance personnel manually bend the control handle 11 to drive the control handle 11 to rotate, the two push blocks 42 are driven to move outward from the cabinet frame 1 to apply an outward thrust to the corresponding folding bottom plate 21.

[0032] The side panel locking assembly 5 is rotatably mounted on the cabinet frame 1 , and the following description will take the cooperation between the folding side panel 2 on one side and the side panel locking assembly 5 as an example.

[0033] Reference Figures 3 to 6 , three groups of side panel locking components 5 are arranged at intervals along the vertical direction, and the three groups of side panel locking components 5 correspond to the folding bottom plate 21, the middle plate 22 and the folding top plate 23 respectively, thereby improving the stability of the entire folding side plate 2 after installation with the cabinet frame 1. Among them, the folding bottom plate 21, the middle plate 22 and the folding top plate 23 are all provided with a locking matching structure that matches the corresponding side panel locking component 5 on the side close to the cabinet frame 1. The following is an explanation of the matching between the folding bottom plate 21 and the corresponding side panel locking component 5.

[0034] Reference Figures 5 to 7The locking matching structure is located at the middle position of the top side of the folding bottom plate 21 in the horizontal direction, and the locking matching structure includes a T-slot 24, a notch slot 25 and a slot 26. The notch slot 25 is located at the top of the T-slot 24, and the notch slot 25 is connected to the T-slot 24. The size of the notch slot 25 is larger than that of the T-slot 24, which is convenient for processing the T-slot 24 on the one hand; on the other hand, it is convenient for the side panel locking assembly 5 to enter the T-slot 24 after rotation to lock and limit the movement of the folding bottom plate 21 in the horizontal directions. The slot 26 is opened on the slot wall of the notch slot 25 in the horizontal direction and is connected to the notch slot 25. After the side panel locking assembly 5 is rotated, it is suitable for being inserted into the slot 26 to lock and limit the up and down movement of the folding bottom plate 21.

[0035] Specifically, the side panel locking assembly 5 includes a swing lever 51 and a locking plate 52. The locking plate 52 is located at the T-slot 24 in the middle of the folding bottom plate 21, and the locking plate 52 is rotatably disposed on the cabinet frame 1. The middle portion of the swing lever 51 is rotatably disposed on the cabinet frame 1 between the locking plate 52 and the push block 42. The swing direction of the swing lever 51 is perpendicular to the swing direction of the locking plate 52, that is, the locking plate 52 rotates in the up-and-down direction; the swing lever 51 rotates in the left-and-right direction.

[0036] Reference Figures 5 to 7 A driving lever 421 is fixedly installed on one side of the push block 42 near the locking plate 52, and a hinge plate is hingedly connected to the driving lever 421, and the two sides of the hinge plate are respectively hinged to the driving lever 421 and the swing lever 51; a guide column is fixedly provided on the swing lever 51, and an arc groove is provided on the cabinet frame 1 for the guide column to be inserted and rotated in a directional manner. Then, when the push block 42 moves telescopically, the swing lever 51 can synchronously swing back and forth under the action of the push block 42 to lock or unlock the folding bottom plate 21.

[0037] The top of the locking plate 52 is fixedly provided with stopper posts 53 that can fit into the T-slot 24 on both sides. When the push block 42 is in the extended state, the push block 42 drives the swing lever 51 to rotate. The swing lever 51 applies a thrust to the locking plate 52 to drive the top of the locking plate 52 to rotate toward the notch 25, so that the top of the locking plate 52 and the two stopper posts 53 pass through the notch 25 and are inserted into the T-slot 24 to lock the horizontal movement of the folding bottom plate 21. At this time, the end of the swing lever 51 close to the locking plate 52 is suitable for being inserted into the slot 26 to lock the up and down movement of the folding side plate 2.

[0038] Reference Figure 6 and Figure 7, wherein the rotation axis of the locking plate 52 is not located in the middle of the locking plate 52, but close to one end where the limiting column 53 is set. In this way, the center of gravity of the locking plate 52 is located on the side of the locking plate 52 away from the limiting column 53. When the push block 42 is extended, the driving lever 421 is suitable for driving the swing lever 51 to disengage from the slot 26, and rotate and reset without contacting the locking plate 52 to achieve unlocking. At this time, the locking plate 52 automatically rotates and resets under the action of gravity and its own center of gravity to completely disengage from the T-slot 24 to achieve unlocking.

[0039] A linkage rod 54 is installed on the swing lever 51 near the push block 42, and the linkage rod 54 is connected with the other two swing levers 51 to achieve synchronous movement. Thus, the entire unlocking and locking process is more linked and automated, and only the control handle 11 needs to be operated.

[0040] The implementation principle of the compact center cabinet that is easy to disassemble and assemble in the embodiment of the present application is as follows: when the side panels need to be removed to repair the electronic components inside the cabinet frame 1, the front panel 12 is opened, the drive motor 31 is started to rotate and the steel wire rope 34 is loosened to drive the folding side panel 2 to descend; at the same time, the control handle 11 is rotated to push the block 42 to extend, and the drive lever 421 is suitable for driving the swing lever 51 to disengage from the slot 26, and rotate and reset without contacting the locking plate 52 to achieve unlocking. The locking plate 52 automatically rotates and resets under the action of gravity and its own center of gravity to completely disengage from the T-slot 24 to achieve unlocking, and multiple side panel locking components 5 are all unlocked in conjunction. Since the steel wire rope 34 is in a relaxed state, the hinge of the folding bottom plate 21 and the middle plate 22 is pushed and then bent and folded toward the outside of the cabinet frame 1. After the folding bottom plate 21 and the middle plate 22 are folded, as the steel wire rope 34 continues to relax and the middle plate 22 is tilted by the thrust, the folding top plate 23 will be folded on the middle plate 22 more smoothly, and the maintenance personnel can directly stand on the folded folding side plate 2 to intuitively see each electronic component inside the cabinet frame 1.

[0041] When the maintenance is completed and the folding side panel 2 needs to be installed on the cabinet frame 1, the driving motor 31 is started to rotate and the steel wire rope 34 is wound to drive the folding top panel 23 to rotate and then rise. After the folding side panel 2 is fully unfolded, the staff can apply an inward thrust to the position of the side panel push-out assembly 4 outside the folding side panel 2, so that the side panel push-out assembly 4 is retracted and drives the control handle 11 to rotate and reset, or directly rotate and reset the control handle 11. After the control handle 11 is reset, it will drive the swing lever 51 to rotate and insert into the slot 26 to lock and limit the vertical movement of the folding side panel 2. At the same time, the swing lever 51 will drive the locking plate 52 to rotate and insert into the T-slot 24 to lock and limit the movement of the folding side panel 2 in both horizontal directions, thereby improving the convenience and stability of the installation and fixation of the folding side panel 2.
