[0002] In low-voltage power distribution systems, multi-functional circuit breakers, as core protection devices, are frequently used for installation and maintenance in electrical cabinets. Existing technologies mostly use bolt-nut combinations or screw-through fixing structures, requiring the use of screwdrivers and wrenches to complete alignment and tightening operations during installation.

[0003] However, the narrow interior of the electrical cabinet limits the space for tool operation, and the position needs to be repeatedly adjusted to ensure that the circuit breaker is installed in the center. When the circuit breaker needs to be replaced or repaired, the traditional bolt fixing structure requires screwdrivers and wrenches to be used to rotate the bolts one by one. This operation is time-consuming and not convenient for the quick installation and fixing of the circuit breaker.

[0004] Therefore, how to achieve quick hand-tightening of the bolts connecting the circuit breaker and the electrical cabinet through structural innovation, without the time-consuming operation of aligning with additional tools, has become a technical problem that urgently needs to be solved in this field.

[0030] 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.

[0031] Example 1: This utility model provides the following... Figure 1-5 The multi-functional circuit breaker shown is easy to install and includes: a circuit breaker body 1, a fixed component and a rotating component;

[0032] It should be noted that the fixing component is used to fix the circuit breaker body 1 to the inner wall of the electrical cabinet, and the rotating component is used to assist the gripping and rotation of the plug-in part. The circuit breaker body 1 refers to the working principle of the C60N circuit breaker. In addition to basic overload and short circuit protection, it also supports current and voltage measurement functions. It realizes parameter monitoring by connecting to the signal module and can be used with a remote control and monitoring system.

[0033] Specifically, the fixing component includes a plug-in part, the end of which is inserted and connected to the front of the circuit breaker body 1, and a limiting part for limiting the plug-in part is provided at the insertion point between the plug-in part and the circuit breaker body 1.

[0034] The rotating assembly includes a sleeve portion, which is disposed at the insertion point between the plug portion and the circuit breaker body 1 and is located on the front side of the circuit breaker body 1. One end of the sleeve portion is inserted and connected to the top of the plug portion. A positioning portion for limiting the sleeve portion is provided at the insertion point between the sleeve portion and the circuit breaker body 1.

[0035] Furthermore, the plug-in part includes fixing bolts 2, one end of each fixing bolt 2 is inserted and connected to the front of the circuit breaker body 1, and the fixing bolts 2 are used to insert and connect the circuit breaker body 1 and the inner wall of the electrical cabinet.

[0036] Specifically, the limiting part includes: a limiting groove 101 and a fixing nut 201;

[0037] It should be noted that multiple limiting grooves 101 are opened at the intersection of the circuit breaker body 1 and the fixing bolt 2 and are located on the back of the circuit breaker body 1, and the fixing nut 201 is sleeved on the outside of the fixing bolt 2 and is located in the inner cavity of the limiting groove 101.

[0038] Specifically, the limiting groove 101 is a hexagonal groove shape, which limits the fixing nut 201. The front of the circuit breaker body 1 has a through cylindrical hole for the fixing bolt 2 to pass through, and the through cylindrical hole is connected to the inner cavity of the limiting groove 101.

[0039] Furthermore, the socket includes: a rotating post 3 and a hexagonal hole 301;

[0040] It should be noted that one end of the rotating column 3 is inserted and connected to the other end of the fixing bolt 2, and the hexagonal hole 301 is opened at one end of the rotating column 3. The hexagonal hole 301 is used to limit the insertion of the fixing bolt 2 and the rotating column 3.

[0041] Specifically, the operator presses the rotating column 3, causing the other end of the fixing bolt 2 to enter the hexagonal hole 301. The head of the other end of the fixing bolt 2 is a hexagonal ring block, which, when matched with the hexagonal hole 301, prevents the end of the fixing bolt 2 from rotating within the cavity of the hexagonal hole 301. A guide groove 303 is provided on the inner wall of the hexagonal hole 301. The guide groove 303 is used to assist in the alignment and positioning of the fixing bolt 2 and the rotating column 3. After the end of the fixing bolt 2 is inserted into the hexagonal hole 301, the operator rotates the rotating column 3 to drive the fixing bolt 2 to rotate synchronously, which facilitates the rapid fixing of the circuit breaker body.

[0042] Example 2: A positioning part applied to the easy-to-install multi-functional circuit breaker in Example 1.

[0043] Specifically, the positioning part includes: a limiting ring 4 and a movable groove 102;

[0044] It should be noted that the limiting ring 4 is located on the outer side of one end of the rotating column 3, the movable groove 102 is opened at the intersection of the rotating column 3 and the circuit breaker body 1, and the limiting ring 4 is located in the inner cavity of the movable groove 102.

[0045] It should be noted that the limiting ring 4 and the rotating column 3 are fixed by integral injection molding. The movable groove 102 is a cylindrical groove. The rotating column 3 is restricted by the limiting ring 4 and cannot be separated from the movable groove 102. A friction groove 302 is opened around the outer side of the rotating column 3. The friction groove 302 is used to increase the friction force on the surface of the rotating column 3.

[0046] In actual use, the circuit breaker body 1 is fixed to the inner wall of the electrical cabinet by using the fixing bolt 2 and fixing nut 201 in the fixing assembly. A rotating assembly is provided on the outside of the fixing bolt 2. The rotating column 3 in the rotating assembly passes through the outside of the fixing bolt 2. The operator can directly hold and rotate the fixing bolt 2 by the rotating column 3 without the need for additional tools, so as to quickly fix the circuit breaker body 1 and avoid the time-consuming alignment of additional tools, thus facilitating the quick fixation of the circuit breaker body.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
