In this embodiment, the fixing parts are specifically fixing bolts. After the fixing parts pass through the mounting holes, they are connected to the base 001, so that the cabinet 101 can be stably fixed on the base 001; a protection cover 104, the cabinet 101 is provided with a protection cover 104 for protecting the fixing parts. Specifically, the protection cover 104 is rotatably mounted on the lower part of the cabinet 101, and the protection cover 104 can be rotated onto the mounting plate 103 to protect the fixing parts and improve the installation stability of the cabinet 101. A total of four groups of mounting plates 103 and protection covers 104 are provided, and the four groups of protection covers 104 are evenly arranged on the left side, right side and rear side of the lower part of the cabinet 101. When not in use, the mounting plates 103 and the protection covers 104 can be folded to a position close to the cabinet 101, reducing the risk of accidental collision during transportation and in densely arranged scenarios by reducing the proportion of the protruding amount; a protection frame 102, the protection frame 102 is fixedly mounted on the top of the cabinet 101; a moving mechanism, the cabinet 101 is provided with a moving mechanism for conveniently moving the cabinet. The moving mechanism can be folded into the protection frame 102, and the protection frame 102 protects the moving mechanism to improve its safety and extend the service life of the moving mechanism.

[0029] Refer to Figure 3 - Figure 8, the moving mechanism consists of a moving sub-group and a control sub-group. There are two sets of the moving sub-group, which are respectively arranged on the left and right sides of the cabinet 101, and the control sub-group is arranged between the two sets of the moving sub-group; The moving sub-group includes: guide rails 201, which are fixedly installed on the top of the cabinet 101. Each set of the moving sub-group is provided with two parallel guide rails 201. The guide rails 201 of the two sets of the moving sub-group are respectively arranged on the left and right sides of the top of the cabinet 101, and all the guide rails 201 are arranged below the protection frame 102; rotating frames 202, which are rotatably arranged on both sides of the cabinet 101. Specifically, a connecting part is provided at the end of the rotating frame 202, and the rotating frame 202 is rotatably installed on the cabinet 101 through the connecting part and the guide rail 201. The rotating frame 202 is also slidably installed between the guide rails 201. The connecting part is used to prevent the rotating frame 202 from detaching from the guide rail 201 and ensure the installation stability of the rotating frame 202; support frames 203, which are slidably installed below the rotating frame 202; universal wheels 204, which are fixedly installed at the bottom of the support frame 203; adjusting bolts 205, which are arranged between the rotating frame 202 and the support frame 203. The adjusting bolt 205 is threadedly installed with the rotating frame 202. A row of holes for the adjusting bolt 205 to pass through is provided on the support frame 203. By rotating the adjusting bolt 205 to make it pass through the holes on the support frame 203, the relative position between the rotating frame 202 and the support frame 203 can be fixed. The advantage of installing the rotating frame 202 on the cabinet 101 through the guide rail 201 is that when the installation of this cabinet is not required, that is, when the moving mechanism is not needed, by rotating and moving the rotating frame 202, the moving mechanism can be stored on the top of the cabinet 101, improving the manageability and safety of the moving mechanism. Refer to Figure 3 - Figure 8, the control sub-group includes: a moving seat 206, the moving seat 206 is slidably installed on the rotating frame 202 on the right side, and the moving seat 206 moves back and forth; a rotating plate 207, the rotating plate 207 is rotatably installed on the front side of the moving seat 206; a threaded rod 208, the threaded rod 208 is arranged on the rotating frame (202) on the right side, specifically, the threaded rod 208 is fixedly installed on the rotating plate 207, and the threaded rod 208 can be angle-folded through the rotating plate 207 and the moving seat 206, by reducing the overall occupied space of the control sub-group, enabling the control sub-group to be better stored and managed; a moving sleeve 209, the moving sleeve 209 is sleeved on the threaded rod 208; a driving member 210, the driving member 210 is fixedly installed on the moving sleeve 209; a connecting ring 211, the connecting ring 211 is rotatably installed on the moving sleeve 209, the connecting ring 211 is threadedly installed with the threaded rod 208, when the connecting ring 211 rotates, it controls the moving sleeve 209 to move relative to the threaded rod 208, the connecting ring 211 is fixedly installed with the output part of the driving member 210, the driving member 210 is an electric device, and the driving member 210 controls the connecting ring 211 to rotate; a hook 212, the hook 212 is fixedly installed at the end of the moving sleeve 209; a convex shaft 213, the convex shaft 213 is fixedly installed on the rotating frame 202 on the left side, and the hook 212 forms a hooking fit with the convex shaft 213; a snap ring 217, a snap ring 217 for fixing the moving sleeve 209 is arranged on the rotating frame 202 where the moving sleeve 209 is located, specifically, the snap ring 217 is fixedly installed on the rotating frame 202 on the right side, refer to Figure 6 , to enable the rotating frame 202 to move smoothly, a groove through which the snap ring 217 can pass is opened on the guide rail 201.

[0030] Refer to Figure 3 - Figure 8 , the moving sub-group further includes: a guide shaft 214, the guide shaft 214 is fixedly installed at the outermost end of the guide rail 201; a limiting frame 215, the limiting frame 215 is slidably installed on the guide shaft 214, the limiting frame 215 is set as a semi-surrounding structure with an opening at the lower part, used to cooperate with the outer end of the guide rail 201 to limit the connecting part of the rotating frame 202, so that the rotating frame 202 can only rotate with its connecting part as the rotation axis, the limiting frame 215 can contact the rotating frame 202, and the end of the limiting frame 215 in contact with the rotating frame 202 is set as an arc surface; a first return spring 216, the first return spring 216 is sleeved on the guide shaft 214, and the two ends of the first return spring 216 are respectively fixed to the guide shaft 214 and the limiting frame 215. The limiting frame 215 is used to limit the position of the movable rotating frame 202, so that while having the function of being storable, it can ensure its original basic stable control function for the cabinet 101, and ensure the use effect of the rotating frame 202.

[0031] First, the rotating frames 202 on both sides are slid outward along the guide rail 201 until the connection part of the rotating frame 202 reaches the outermost end of the guide rail 201, and then the rotating frame 202 is rotated with the connection part as the rotation axis, and the rotating frame 202 and the supporting frame 203 are transferred from the top of the cabinet 101 to the positions on both sides. In this process, the rotating frame 202 will be separated from the limiting frame 215, and the first return spring 216 releases elastic potential energy to control the limiting frame 215 to move downward, so that the limiting frame 215 is sleeved on the connection part of the rotating frame 202, and the rotating frame 202 is constrained by the limiting frame 215 to only rotate around the connection part; Secondly, the adjusting bolt 205 is rotated and fixed to disengage the adjusting bolt 205 from the support frame 203, and the fixing of the supporting frame 203 and the rotating frame 202 by the adjusting bolt 205 is released. Then, the supporting frame 203 is adjusted to move along the rotating frame 202, and the rotating frame 202 is synchronously controlled to rotate, so that the total length of the supporting frame 203 and the rotating frame 202 obviously exceeds the vertical height of the cabinet 101. After the adjustment is completed, the adjusting bolt 205 is tightened in the reverse direction to fix the supporting frame 203 and the rotating frame 202 again. At this time, an angle is formed between the rotating frame 202 and the side elevation of the cabinet 101; After that, the movable seat 206 is moved forward and the rotating plate 207 is rotated, so that the movable sleeve 209 and the threaded rod 208 are rotated to the front side of the cabinet 101 and are in a horizontal state, and then the driving member 210 is started to drive the movable sleeve 209 to extend axially along the threaded rod 208 through the positive rotation of the connecting ring 211 until the total length of the movable sleeve 209 and the threaded rod 208 allows the hook 212 to be hooked on the convex shaft 213, and then the driving member 210 is closed. At this time, a stable A-type support structure is formed between the rotating frame 202, the supporting frame 203, the movable sleeve 209 and the threaded rod 208. For the specific spatial configuration, see Figure 2 As shown; Then, by manipulating the driving member 210 to reverse the connecting ring 211, the movable sleeve 209 is axially contracted along the threaded rod 208, thereby reducing the angle between the two sets of rotating frames 202. During this process, the universal wheel 204 remains in contact with the ground and produces displacement. Therefore, the top of the rotating frame 202 makes a vertical upward movement to achieve the overall lifting of the cabinet box 101 and detach it from the ground. After completion, the driving member 210 is closed; at this time, the cabinet box 101 is in a movable state and can be freely transported, including transferring the cabinet box 101 to the base 001 or removing it from the base 001.

[0032] Therefore, by adjusting the axial relative displacement between the moving sleeve 209 and the threaded rod 208 to change the total length therebetween, the height of the cabinet 101 can be controlled, enabling the moving mechanism to improve the moving convenience and handling efficiency of the present cabinet. The operation process is simple and labor-saving. After the position of the cabinet 101 is transferred, the driving member 210 needs to rotate the connecting ring 211 forward to increase the total length of the moving sleeve 209 and the threaded rod 208, and then the cabinet 101 is smoothly lowered to the target position. Finally, after the cabinet 101 is positioned, the fixing member is used to tightly connect the mounting plate 103 and the base 001 to complete the installation of the present cabinet.

[0033] When performing the folding operation: First, rotate the rotating plate 207 to disengage the hook 212 from the convex shaft 213. Use the driving member 210 to completely screw the moving sleeve 209 into the threaded rod 208. Move the moving seat 206 backward and rotate the rotating plate 207 to lock the moving sleeve 209 into the snap ring 217. Rotate the adjusting bolt 205 to release the fixation between the rotating frame 202 and the support frame 203. After the support frame 203 is retracted into the rotating frame 202, it is re-fastened. Rotate the rotating frame 202 to the storage position at the top of the cabinet 101. During this process, the limiting frame 215 will be moved upward by the rotating frame 202 and the first return spring 216 will be compressed, then the constraint on the connecting part of the rotating frame 202 is released, and then the rotating frame 202 is moved into the protection frame 102, that is, finally the entire moving mechanism is completely retracted into the internal space of the protection frame 102.

[0034] Refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 and Figure 4, the outer end spacing of the split rail 201a is greater than its inner end spacing; the first split frame 202a, the left rotating frame 202 is composed of two first split frames 202a, which are slidably installed between the two first split frames 202a. Under the guiding action of the split rail 201a, a relative position will be generated between them; the second split frame 203a, the left support frame 203 is composed of two second split frames 203a, which are slidably installed between the two second split frames 203a. The two second split frames 203a are correspondingly slidably installed with the two first split frames 202a, and the first split frame 202a will drive the second split frame 203a to generate a relative displacement between the second split frames 203a; the second return spring 218, the second return spring 218 is fixedly installed between the two first split frames 202a and between the two second split frames 203a. The second return spring 218 is used to reset the first split frame 202a and the second split frame 203a that are displaced by the guiding of the split rail 201a; the extension frame 219, the extension frame 219 is fixedly installed on the limiting frame 215. The extension frame 219 is used to extend the contact range of the limiting frame 215, so that the moving first split frame 202a can maintain cooperation with the limiting frame 215; the movable block 220, the movable block 220 is slidably installed at the outer end of the split rail 201a. The movable block 220 is used to prevent the first split frame 202a from falling off the split rail 201a when moving to the left. At the same time, when the two first split frames 202a are closed, the first split frame 202a can cross the movable block 220 so that the first split frame 202a can pass through the split rail 201a; the third return spring 221, the third return spring 221 is fixedly installed between the movable block 220 and the split rail 201a.

[0035] During the process of storing the left moving sub-group into the protection frame 102, the guiding action of the split rail 201a causes the first split frame 202a to drive the second split frame 203a to fold synchronously, and at the same time compress the second return spring 218. That is, at this time, the overall width of the left rotating frame 202 and the support frame 203 is reduced, so that the staggered storage of the left and right moving sub-groups is realized, thereby optimizing the space utilization rate of the top of the cabinet 101; during this process, the first split frame 202a pushes the movable block 220 to displace and compress the third return spring 221, so that the first split frame 202a can smoothly pass through the outermost end of the split rail 201a to ensure the smooth progress of the closing action; when it is necessary to expand the left rotating frame 202 and the support frame 203, under the combined action of the guiding of the split rail 201a and the third return spring 221, the first split frame 202a and the second split frame 203a can return to the working state, and at the same time the first split frame 202a passes through the movable block 220 in the reverse direction. Through the above expansion scheme, by reducing the plane occupation ratio of the horizontal layout of the moving mechanism, the use of the moving mechanism does not generate negative feedback on this cabinet, that is, the basic size of the cabinet 101 does not need to reserve redundant space for the moving mechanism, effectively improving the overall space utilization rate of this cabinet.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 9 and Figure 10 ,including: mounting rods 301. Two mounting rods 301 are fixedly installed inside the bottom of the cabinet 101, and the two mounting rods 301 are arranged front and back; sleeve rods 302. Sleeve rods 302 are slidably sleeved on both of the two mounting rods 301; threads 303. Threads 303 are provided on the rear sleeve rod 302, and this sleeve rod 302 is threadedly installed with the cabinet 101, and the front sleeve rod 302 is slidably installed with the cabinet 101; a turning handle 304 fixedly installed on the rear sleeve rod 302; abutting blocks 305. Abutting blocks 305 are rotatably installed at the ends of both sleeve rods 302, and the abutting blocks 305 are arranged on the left and right outer sides of the cabinet 101, and the abutting blocks 305 can be rotated to a state beyond the lower part of the cabinet 101; a gear 306. A gear 306 is rotatably installed inside the cabinet 101; racks 307. Two racks 307 are slidably installed inside the cabinet 101, and both of the two racks 307 are engaged with the gear 306. One of the racks 307 is rotatably installed with the sleeve rod 302 provided with threads 303, and the other rack 307 is fixedly installed with the other sleeve rod 302. Through the cooperation of the gear 306 and the racks 307, the two sleeve rods 302 will move synchronously and in opposite directions; supporting convex parts 308. Supporting convex parts 308 are fixedly installed on both sides of the lower part of the cabinet 101, and the supporting convex parts 308 are used to support the abutting blocks 305 during the transportation of this cabinet, preventing the abutting blocks 305 from rotating to a state of protruding from the cabinet 101, thereby reducing the possibility of damage to the abutting blocks 305 caused thereby.

[0037] First, use the turning handle 304 to rotate the rear sleeve rod 302, and through the cooperation of the gear 306 and the racks 307, move the two sleeve rods 302 out of the left and right sides of the cabinet 101 respectively, so that the distance between the two abutting blocks 305 is greater than the base 001, and rotate the two abutting blocks 305 to face downward, beyond the lower part of the cabinet 101; after transferring the cabinet 101 to the base 001, reverse the turning handle 304 to control the two sleeve rods 302 to retract into the cabinet 101. During this process, since the position of the cabinet 101 is not centered, one of the abutting blocks 305 will first contact the base 001, and then continue to rotate the turning handle 304. Due to the action of the gear 306 and the racks 307, the two abutting blocks 305 will move towards the cabinet 101 simultaneously, and the absolute position of the abutting block 305 that first contacts the base 001 remains unchanged. Therefore, the other abutting block 305 and the cabinet 101 will move towards this abutting block 305, making the cabinet 101 gradually centered on the base 001 until the other abutting block 305 also abuts against the base 001. At this time, the position adjustment of the cabinet 101 is completed. That is, using this cabinet can conveniently find the installation position on the base 001, improving the installation effect of this cabinet while facilitating the installation.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention.
