[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides an easy-to-install central cabinet, including a cabinet body 1 and multiple connecting rods 3. Two sets of parallel connecting components are provided on one side of the cabinet body 1. Each connecting component includes multiple fixing groups, and each fixing group includes two fixing ears 2 fixed to one side of the cabinet body 1. A rotating block 7 is rotatably connected between the two fixing ears 2. A slot 8 for placing the connecting rods 3 is provided on one side of the rotating block 7. Limiting components for fixing the connecting rods 3 in the slot 8 are provided on both the upper and lower sides of the rotating block 7. A locking component for fixing the connecting rods 3 in the slot 8 is provided on one side of the rotating block 7. In use, the connecting rods 3 are first inserted into the multiple fixing groups in the same row on one of the cabinet bodies 1. Within the slot 8 of the inner rotating block 7, the connecting rod 3 is fixed using a limiting component and a locking component. Then, the remaining cabinet 1 is moved from the front side of the connecting rod 3 to the rear side, so that the rotating block 7 on the rear side of the other cabinet 1 contacts the connecting rod 3 and the connecting rod 3 is inserted into the slot 8. The limiting component is used to limit the other cabinet 1, thereby aligning the two cabinets 1 horizontally. Then, the other cabinet 1 is moved horizontally until the two cabinets 1 contact each other or remain at a certain distance. The locking component is then used to fix the other cabinet 1, thereby fixing the two cabinets 1 together. The installation of the cabinet 1 can be achieved without multiple adjustments to its position, improving the assembly efficiency of the central cabinet.

[0024] The limiting component includes a groove 13 on one side of the rotating block 7. A positioning frame 16 is slidably connected in the groove 13. One end of the positioning frame 16 that contacts the connecting rod 3 is inclined. Positioning slots 9 are provided on both the upper and lower sides of the connecting rod 3. One end of the positioning frame 16 is inserted into the positioning slot 9. A pressing component is provided between the groove 13 and the positioning frame 16 to push the positioning frame 16 toward the connecting rod 3. When the connecting rod 3 is inserted into the slot 8, the connecting rod 3 will press the inclined surface of the positioning frame 16, causing the positioning frame 16 to slide in the groove 13, thereby allowing the connecting rod 3 to be inserted into the slot 8. When one end of the positioning frame 16 is above or below the positioning slot 9, under the action of the pressing component, one end of the positioning frame 16 is inserted into the positioning slot 9, thereby limiting the front and rear position of the connecting rod 3, so that the connecting rod 3 can only move horizontally and cannot move forward and backward, thus improving the accuracy of the horizontal alignment of the device.

[0025] The extrusion assembly includes a first magnetic block 14 bonded to the top of the slide groove 13, and second magnetic blocks 15 bonded to the top of both sides of the positioning frame 16. The first magnetic block 14 and the second magnetic block 15 repel each other, thereby subjecting the positioning frame 16 to a pushing force, so that the positioning frame 16 can be stuck into the positioning groove 9, improving the stability of the horizontal alignment of the connecting rod 3.

[0026] The locking assembly includes a rotating plate 12 that rotates on one side of the rotating block 7. A rubber post 17 is bonded to one side of the rotating plate 12. Multiple evenly distributed positioning holes 10 are provided on one side of the connecting rod 3, and the rubber post 17 can be inserted into the positioning holes 10. A positioning mechanism for auxiliary fixing of the rotating plate 12 is provided on one side of the rotating block 7. A rubber ring 18 is integrally formed on the outer circumference of one end of the rubber post 17. When one end of the rubber post 17 enters the positioning hole 10, it provides auxiliary fixing to prevent the rotating plate 12 from easily rotating. A clearance groove 11 is provided at one end of the positioning hole 10. 7. When rotating into the positioning hole 10, the rubber column 17 is positioned to allow it to enter the positioning hole 10. Rotating the rotating plate 12 causes the rubber column 17 on the rotating plate 12 to rotate together with the rotating plate 12, thereby inserting the rubber column 17 into the positioning hole 10. This fixes the horizontal position of the connecting rod 3 in the slot 8, preventing the connecting rod 3 from moving within the slot 8. Consequently, when another cabinet 1 moves, the connecting rod 3 will not move with it. At the same time, it can also position and fix multiple cabinets 1, reducing the time required for device alignment and further improving the assembly efficiency of the central cabinet.

[0027] The positioning mechanism includes a fixed plate 19 welded to one side of the rotating block 7. A placement groove is provided on one side of the fixed plate 19, and a rubber ball 20 is bonded in the placement groove. Both sides of the rotating plate 12 are provided with arc-shaped grooves 21, and the rubber ball 20 is located in the arc-shaped grooves 21. During the rotation of the rotating plate 12, the arc-shaped grooves 21 on the rotating plate 12 will squeeze the rubber ball 20, causing the rubber ball 20 to deform and detach from the arc-shaped grooves 21, thereby allowing the rotating plate 12 to rotate freely. When the rubber ball 20 is located in the arc-shaped grooves 21, the rubber ball 20 will limit the rotating plate 12, keeping the rotating plate 12 in this position, which facilitates the connecting rod 3 to be inserted into the slot 8, improving the smoothness of the connecting rod 3 entering the slot 8.

[0028] The rotating block 7 has a rotating shaft 6 welded to both the upper and lower sides, which passes through the fixed ear 2. The outer circumference of the rotating shaft 6 is fixed with a coil spring 4 by bolts, and the other end of the coil spring 4 is fixed to the fixed ear 2, which limits the angle of the rotating block 7, so that the rotating block 7 can maintain this position for a long time, preventing the rotating block 7 from rotating and the connecting rod 3 from being unable to be inserted into the slot 8, thus improving the accuracy of the connecting rod 3 being inserted into the slot 8.

[0029] Among them, the two fixed ears 2 in the same group are both fixed with protective covers 5 by threads on opposite sides, and the coil spring 4 is located inside the protective cover 5 to protect the coil spring 4, prevent the coil spring 4 from being over-wound and damaged, and improve the service life of the coil spring 4.

[0030] The working principle of this utility model is as follows: In use, firstly, the connecting rod 3 is inserted into the slot 8 of the rotating block 7 within the same row of multiple fixed groups on a cabinet 1. When the connecting rod 3 is inserted into the slot 8, it presses against the inclined surface of the positioning frame 16, causing the positioning frame 16 to slide within the sliding groove 13, thus allowing the connecting rod 3 to be inserted into the slot 8. When one end of the positioning frame 16 is above or below the positioning groove 9, the first magnetic block 14 pushes the second magnetic block 15, causing the positioning frame 16 to receive a thrust, thereby inserting the positioning frame 16 into the positioning groove 9, thus limiting the forward and backward position of the connecting rod 3. Rotating the rotating plate 12 causes the rubber post 17 on the rotating plate 12 to rotate along with the rotating plate 12, thus inserting the rubber post 17 into the positioning hole 10. The horizontal position of connecting rod 3 within the slot 8 is fixed, preventing it from moving further within the slot. This pushes another cabinet 1 from the front to the rear of connecting rod 3, causing the rotating block 7 on the rear side of this cabinet 1 to contact connecting rod 3 and engage connecting rod 3 within the slot 8. The positioning frame 16 and positioning groove 9 then horizontally limit the connection, aligning the two cabinets 1 horizontally. After horizontally moving cabinet 1 until the two cabinets 1 are in contact or at a certain distance, the rotating plate 12 is rotated, causing the rubber column 17 to insert into the positioning hole 10. This fixes the horizontal position of connecting rod 3 within the slot 8, thus securing the two cabinets 1 together. This eliminates the need for multiple adjustments to the cabinet 1's position, improving the assembly efficiency of the central cabinet.

[0031] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
