It has a large capacity, can be equipped with multiple function releases and more auxiliary contacts, has a high segmentation capacity and thermal stability, so it is often used in places requiring high breaking capacity and selective protection.

[0003] There are many existing technologies for the plug-in frame bracket, such as:

However, the current circuit breaker frame bracket generally clips onto the circuit breaker surface by side rotation, so it is inconvenient to disassemble. When the disassembly is inconvenient, it may lead to excessive force or violent disassembly during disassembly. For the circuit breaker frame bracket with a plastic structure, it is easy to cause deformation or damage to the mounting bracket. In addition, during the installation process, it is necessary to squeeze the circuit breaker frame bracket towards the circuit breaker with great effort, which may also easily cause damage to the circuit breaker.

[0007] In view of this, the utility model provides a combined plug-in frame bracket. Utility Model Content

[0030] Most of the time, when the circuit breaker needs to be replaced or repaired, the circuit breaker needs to be removed from the mounting bracket. However, the current circuit breaker frame bracket generally rotates sideways to clip the buckle on the circuit breaker surface, so it is inconvenient to disassemble. When the disassembly is inconvenient, excessive force or violent disassembly may occur during disassembly. For the circuit breaker frame bracket with a plastic structure, it is easy to cause deformation or damage to the mounting bracket. In addition, during the installation process, the circuit breaker frame bracket needs to be squeezed toward the circuit breaker with great effort, which may also easily cause damage to the circuit breaker.

[0031] like Figure 1-5 As shown, the device includes a panel fixing assembly 10;

[0032] The panel fixing assembly 10 is used to fit the surface of the circuit breaker to protect the circuit breaker panel;

[0033] A back fixing component 20 is provided on the surface of the panel fixing component 10, and the back fixing component 20 is clamped on the back of the circuit breaker to protect the back of the circuit breaker;

[0034] The panel fixing assembly 10 is connected by elastic force, thereby extending the installation path of the panel fixing assembly 10, and the panel fixing assembly 10 and the back fixing assembly 20 can be fixed on the surface of the circuit breaker by lateral pushing;

[0035] At present, the circuit breaker plug-in frame bracket generally clamps the buckle on the circuit breaker surface by rotating sideways, so it is inconvenient to disassemble. When disassembly is inconvenient, it will lead to excessive force and violent disassembly during disassembly. For the circuit breaker plug-in frame bracket with a plastic structure, it is easy to cause deformation or damage of the mounting bracket, and it is necessary to squeeze the circuit breaker plug-in frame bracket toward the circuit breaker with effort during the installation process, which is also easy to cause damage to the circuit breaker. Therefore, the panel fixing assembly 10 includes a fixing frame 11, and a rotating rod 12 is rotatably connected inside the fixing frame 11. Torsion springs 13 are installed on both sides of the rotating rod 12. The other end of the torsion spring 13 is connected to the fixing frame 11, and the elastic force generated by the torsion spring 13 is used to correct the position of the rotating rod 12. The surface of the rotating rod 12 is connected with a connecting rod 14;

[0036] The connecting rod 14 allows the rotating rod 12 to rotate at most 60°. An elastic member 15 is installed inside the connecting rod 14. The other end of the elastic member 15 is connected to a fixed block 16. The fixed block 16 and the connecting rod 14 are slidably connected. The elastic force generated by the elastic member 15 pushes the fixed block 16 to move laterally. The surface of the connecting rod 14 is slidably connected to a support block 17. The surface of the support block 17 is provided with a groove. The fixing block 16 passes through the groove to fix the connecting rod 14 inside the support block 17. The surface of the support block 17 is provided with a clamping block 18.

[0037] The back fixing assembly 20 includes a support plate 21, the support plate 21 is mounted on the surface of the clamping block 18, an extension block 22 is provided on the surface of the support plate 21, a load-bearing bottom plate 24 is provided on the surface of the support plate 21, and a reinforcement rod 23 is provided between the support plate 21 and the load-bearing bottom plate 24;

[0038] Depend on Figure 2-Figure 5 As shown, firstly, the rotating rod 12 is attached to the circuit breaker panel, and then the supporting plate 21 is attached to the back of the circuit breaker, and at the same time, the extension block 22 is inserted from the side of the circuit breaker, and then the clamping block 18 is clamped on the surface of the extension block 22, and then the fixing frame 11 is pressed against the circuit breaker panel and the connecting rod 14 is rotated, and the connecting rod 14 is aligned with the supporting block 17, and then the connecting rod 14 is slid toward the inside of the supporting block 17;

[0039] When the connecting rod 14 slides laterally into the support block 17, the fixing block 16 will be squeezed, so that the fixing block 16 will retract into the connecting rod 14. Then, when the fixing block 16 moves to the groove of the support block 17, the elastic member 15 generates elastic force to push the fixing block 16 upward, so that the fixing block 16 is stuck at the connecting rod 14 and the support block 17, and the connecting rod 14 is fixed inside the support block 17, so that the connecting rod 14 is connected through the support block 17, the clamping block 18 and the extension block 22. Through the lateral driving force and the lateral movement, the device does not need to be pulled to move the frame during installation, and only needs to be squeezed laterally, thereby improving the use efficiency of the device.

[0040] Then the load-bearing base plate 24 is installed inside the electrical box, and the connection between the support plate 21 and the load-bearing base plate 24 is increased by the reinforcement rod 23, so as to avoid the support plate 21 and the load-bearing base plate 24 from being broken due to the force on the circuit breaker, thereby improving the use quality of the device, and the circuit breaker is wrapped by the fixed frame 11 and the support plate 21 to improve the protection quality of the circuit breaker.
