Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 8 This utility model provides a high and low voltage switchgear that is fixed side by side, including a cabinet 1. Two connecting seats 4 are connected to one side of the cabinet 1, and a T-shaped connector 20 that matches the connecting seats 4 is connected to the other side. The T-shaped connector 20 is connected to a drive mechanism for driving the T-shaped connector 20 to rotate. The drive mechanism includes two driven teeth 11, a tooth plate 10, a drive tooth 9, and a connecting shaft 8. The connecting shaft 8 is used to drive the drive tooth 9 to rotate. The drive tooth 9 is connected to the tooth plate 10. The tooth plate 10 is used to drive the two driven teeth 11 to rotate synchronously. The driven teeth 11 are connected to the T-shaped connector 20. A protective frame 5 is connected to the inner side of the cabinet 1. The protective frame 5 can protect the drive mechanism. The protective frame 5 is connected to a limiting mechanism for limiting the drive tooth 9.

[0027] When adjacent cabinets 1 are connected, rotating the handle 7 drives the drive gear 9 to rotate in the direction of rotation. Figure 5 As indicated by the central arrow, the driving gear 9 drives the toothed plate 10 to move downwards, gradually stretching the spring 12. The toothed plate 10 drives the two driven gears 11 to rotate, which in turn drives the two T-shaped connectors 20 to rotate, connecting the T-shaped connectors 20 to the connecting grooves 19 of the connecting seat 4, thereby achieving the connection and fixation of adjacent cabinets 1. At the same time, the limiting mechanism automatically locks the driving gear 9 to prevent the two driven gears 11 from rotating and affecting the stability of the connection between adjacent cabinets 1.

[0028] The drive mechanism also includes a guide post 13, a spring 12, and a handle 7. The guide post 13 guides the toothed plate 10, the spring 12 drives the toothed plate 10 to move upward toward the protective frame 5, and the handle 7 drives the connecting shaft 8 to rotate. During the downward movement of the toothed plate 10, the guide post 13 slides relative to the toothed plate 10, the spring 12 is gradually stretched, and the toothed plate 10 slides in connection with the protective frame 5, improving the stability of the toothed plate 10's movement.

[0029] Spring 12 is fitted onto guide post 13, and both ends of spring 12 are connected to toothed plate 10 and protective frame 5.

[0030] One end of the guide post 13 is connected to the protective frame 5, and the other end is inserted into the toothed plate 10 and slidably connected.

[0031] The two ends of the connecting shaft 8 are connected to the handle 7 and the drive gear 9. The drive gear 9 is rotatably connected to the protective frame 5, and the driven gear 11 is rotatably connected to the protective frame 5, so that the drive gear 9 and the driven gear 11 rotate steadily. In conjunction with the use of the guide post 13, it guides the gear plate 10 and ensures the transmission effect between the driven gear 11, the drive gear 9 and the gear plate 10.

[0032] The driving gear 9, driven gear 11, and gear plate 10 are meshed together, resulting in high transmission efficiency and a constant transmission ratio.

[0033] The limiting mechanism includes a push rod 6, a paddle 14, a torsion spring 15, a torsion spring shaft 16, and a rotating head 17. The end of the push rod 6 is connected to the paddle 14, and the rotating head 17 is connected to one end of the paddle 14. The other end of the paddle 14 abuts against the tooth groove of the drive tooth 9. One end of the torsion spring shaft 16 is fixedly connected to the rotating head 17, and the other end is rotatably connected to the protective frame 5. The torsion spring 15 drives the end of the paddle 14 to move closer to the drive tooth 9. During the rotation of the drive tooth 9, the end of the paddle 14 slides on the outside of the drive tooth 9. When the drive tooth 9 stops moving, the torsion spring 15, in conjunction with the paddle 14, causes the end of the paddle 14 to abut against the tooth groove of the drive tooth 9, thus locking and limiting the drive tooth 9. At this time, the spring 12 is in a stretched state. When the drive tooth 9 is released, it pushes the push rod 6 to move, which in turn drives the paddle 14 to rotate, and simultaneously drives the torsion spring shaft 16 to rotate. The torsion spring 15 is tightened, and the end of the paddle 14 separates from the drive tooth 9, thus releasing the drive tooth 9. The stretched spring 12 drives the tooth plate 10 to move upward, which in turn drives the two driven teeth 11 to rotate, and then drives the two T-shaped joints 20 to rotate. When the tooth plate 10 returns to its original position, the T-shaped joints 20 are aligned with the connecting groove 19, which facilitates the separation of the T-shaped joints 20 from the connecting seat 4, and thus facilitates the separation of adjacent cabinets 1.

[0034] The torsion spring 15 is fitted onto the torsion spring shaft 16, and both ends of the torsion spring 15 are connected to the rotating head 17 and the protective frame 5.

[0035] Four positioning seats 2 are connected to one side of cabinet 1, and four limiting posts 3 are connected to the other side. The limiting posts 3 are matched with the positioning seats 2. When adjacent cabinets 1 are connected, the limiting posts 3 are inserted into the corresponding positioning seats 2, at which time the T-shaped connector 20 is aligned with the rectangular hole 18.

[0036] The connector 4 is provided with a rectangular hole 18 and a connecting groove 19, with the rectangular hole 18 communicating with the connecting groove 19. The T-shaped connector 20 passes through the rectangular hole 18 and abuts against the inner side of the connecting groove 19. Then, the T-shaped connector 20 rotates and connects with the connecting groove 19, thereby achieving a fixed connection between the T-shaped connector 20 and the connector 4.

[0037] Working principle: When connecting adjacent cabinets 1, the limiting post 3 is inserted into the positioning seat 2, at which point the T-shaped connector 20 passes through the rectangular hole 18. Then, rotating the handle 7 drives the connecting shaft 8 and the driving gear 9 to rotate, and the end of the lever 14 slides on the outside of the driving gear 9. The rotation of the driving gear 9 causes the tooth plate 10 to move downwards, thereby driving the two driven teeth 11 to rotate. The driven teeth 11 drive the T-shaped connector 20 to rotate, connecting the T-shaped connector 20 with the connecting groove 19 of the connecting seat 4. At this time, the spring 12 is in a stretched state, achieving the connection and fixation of adjacent cabinets 1. Simultaneously, the end of the lever 14 abuts against the tooth groove of the driving gear 9, achieving positioning and locking of the driving gear 9, preventing the two driven teeth 11 from rotating, improving the stability of the connection between the T-shaped connector 20 and the connecting seat 4, and making operation simple and convenient. When adjacent cabinets 1 need to be separated, push rod 6 is moved, which simultaneously drives the paddle 14 to rotate. Torsion spring 15 is tightened, and the end of paddle 14 separates from drive tooth 9, thus releasing drive tooth 9. The stretched spring 12 drives tooth plate 10 to move upward, which in turn drives two driven teeth 11 to rotate, simultaneously driving two T-shaped joints 20 to rotate. When tooth plate 10 returns to its original position, T-shaped joint 20 aligns with connecting groove 19, which facilitates separation of T-shaped joint 20 from connecting seat 4, thus separating adjacent cabinets 1.
