Description

Technical Field

[0001] This utility model relates to the field of circuit breaker assembly technology, specifically to a circuit breaker that is easy to assemble. Background Technology

[0002] A circuit breaker is a switching device capable of connecting, carrying, and disconnecting normal circuit current, and closing, carrying, and disconnecting abnormal circuit current within a specified time. Based on voltage level, they can be divided into high-voltage circuit breakers (usually referring to 3kV and above) and low-voltage circuit breakers. Their core functions include power distribution, infrequent start-stop control of asynchronous motors, and automatic protection against short circuits, overloads, undervoltage, and other faults in power lines and motors. This device integrates circuit on / off control and multiple protection functions, combining the breaking capacity of a fuse switch with the over / under-temperature protection characteristics of an over / under-temperature relay. It provides comprehensive safety protection for the power supply system. Existing circuit breakers are relatively complex to assemble, requiring manual support to secure them to the mounting bracket, resulting in poor practicality. For example, existing technologies, such as the easily assembled circuit breaker described in the prior art (publication number CN222953007U), involve fixing the mounting base to a wall or counter with multiple screws, then inserting a mounting block from one side of the circuit breaker body into the mounting groove. A limiting component effectively secures the circuit breaker body. When the circuit breaker is damaged during use, only the affected circuit breaker body needs to be disassembled and replaced, without disassembling the entire circuit breaker body or mounting base. This facilitates circuit breaker maintenance and effectively solves the problems of existing technologies. However, its structure still needs improvement, as detailed below:

[0003] In this solution, when a large number of circuit breakers in the computer room fail, it is still necessary to open the limit switch components one by one to replace the circuit breaker body. The assembly process is relatively complicated and can lead to fatigue of maintenance personnel. Therefore, a circuit breaker that is easy to assemble is needed to improve the above problems. Utility Model Content

[0004] To address the issue that when a large number of circuit breakers fail during assembly, it is still necessary to sequentially open the limit switches to replace the circuit breaker bodies, which involves complex assembly steps and can lead to fatigue for maintenance personnel, this invention provides a circuit breaker that is easy to assemble and disassemble, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circuit breaker that is easy to assemble includes a fixed base plate, a fixed base is provided on the outer wall of the fixed base plate, an electrically controlled magnet is embedded in the inner wall of the fixed base, a circuit breaker is plugged into and installed on the outer wall of the fixed base, an iron block is embedded in the bottom outer wall of the circuit breaker, and a slot is provided on the side wall of the circuit breaker. A limit groove is provided on one side of the electrically controlled magnet located on the side wall of the fixed base.

[0007] A fixing component is installed on the side wall of the fixed base plate, and LED lights are embedded in the outer wall of the fixed base plate. Multiple sets of LED lights are provided and are located on the outer wall of the fixed base plate.

[0008] As a preferred embodiment of this utility model, the fixing component includes a mounting plate and a fixing shaft. The mounting plate is installed on the side wall of the fixing base plate, and a controller is installed on the outer wall of the mounting plate.

[0009] As a preferred embodiment of this utility model, the outer wall of the mounting plate is provided with mounting holes, and multiple sets of mounting holes are provided and located on the outer wall of the mounting plate respectively. A limit guide rod is slidably connected to the inner wall of the mounting hole.

[0010] As a preferred embodiment of this utility model, a sliding plate is installed at one end of the limiting guide rod, wherein the sliding plate is slidably connected to the inner wall of the fixed base plate, and a limiting spring is installed on the outer wall of the sliding plate, and the limiting spring is located on one side of the limiting guide rod.

[0011] As a preferred embodiment of this utility model, the limiting springs are provided in multiple sets and are respectively located on the outer wall of the sliding plate, and the side wall of the sliding plate is provided with fixing pins from left to right.

[0012] As a preferred embodiment of this utility model, one end of the fixing pin is inserted and pulled into the inner wall of the limiting groove, and the fixing pin is slidably connected to the inner wall of the slot, and the fixing shaft is rotatably connected to the opposite side wall of the fixing base plate.

[0013] As a preferred embodiment of this utility model, a limiting rod is rotatably connected to the outer wall of the fixed rotating shaft, wherein the cross-section of the limiting rod is a concave shape.

[0014] As a preferred embodiment of this utility model, a pull rod is installed on one side of the limiting guide rod and on the outer wall of the sliding plate, wherein one end of the pull rod passes through the mounting plate and extends to the outer wall of the mounting plate where a pull block is installed, and the controller is connected to an electrically controlled magnet via a wire and the connection method is an electrical connection.

[0015] Compared with existing technologies, this utility model can fix the circuit breaker by setting an electrically controlled magnet and a fixed base in a circuit breaker that is easy to assemble. The controller controls the electrically controlled magnet to generate magnetism. The circuit breaker only needs to be fixed by clipping it onto the outer wall of the fixed base, so that the electrically controlled magnet magnetically attracts the iron block. There is no need to hold the circuit breaker. After the electrically controlled magnet magnetically attracts the circuit breaker, the limit rod is moved so that the limit rod rotates on the fixed shaft, thereby fixing the limit rod onto the outer wall of the circuit breaker. This facilitates installation and solves the problem that the assembly of existing circuit breakers is relatively complicated, requiring the circuit breaker to be held by hand and clipped onto the mounting frame for fixation, which is not very practical.

[0016] This invention utilizes a controller within a circuit breaker designed for easy assembly to activate an electrically controlled magnet. This magnet magnetically attracts and secures an iron block. Pulling up the pull block moves the sliding plate to one side, which in turn moves the fixing pin to the same side, disengaging it from the slot and limit groove. Simultaneously pulling down the limit rod applies a pulling force to the circuit breaker, causing it to disengage from the iron block and the magnet. This allows one or more circuit breakers to be removed, simplifying assembly and eliminating the need for sequentially opening the limit components to replace the circuit breaker body, which is complex and can lead to maintenance fatigue.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5 The circuit breaker shown is easy to assemble and install, including a fixed base plate 1, a fixed base 2 is provided on the outer wall of the fixed base plate 1, an electric control magnet 3 is embedded in the inner wall of the fixed base 2, a circuit breaker 4 is plugged and installed on the outer wall of the fixed base 2, an iron block 5 is embedded in the bottom outer wall of the circuit breaker 4, and a slot 6 is opened on the side wall of the circuit breaker 4. A limit groove 7 is opened on one side of the electric control magnet 3 and on the side wall of the fixed base 2.

[0025] A fixing component 8 is installed on the side wall of the fixing base plate 1, and an LED light 9 is embedded in the outer wall of the fixing base plate 1. The LED light 9 is provided in multiple sets and is located on the outer wall of the fixing base plate 1.

[0026] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing component 8 includes a mounting plate 801 and a fixing shaft 802. The mounting plate 801 is mounted on the side wall of the fixing base plate 1. A controller 803 is mounted on the outer wall of the mounting plate 801. Multiple sets of mounting holes 804 are provided on the outer wall of the mounting plate 801. A limit guide rod 805 is slidably connected to the inner wall of the mounting hole 804. A sliding plate 806 is mounted on one end of the limit guide rod 805. The sliding plate 806 is slidably connected to the inner wall of the fixing base plate 1. A limit spring 807 is mounted on the outer wall of the sliding plate 806, and the limit spring 807 is located on one side of the limit guide rod 805. Multiple limit springs 807 are provided. The components are located on the outer wall of the sliding plate 806. From left to right, the side wall of the sliding plate 806 is provided with a fixing pin 808. One end of the fixing pin 808 is inserted and pulled into the inner wall of the limiting groove 7, and the fixing pin 808 is slidably connected to the inner wall of the slot 6. The fixing shaft 802 is rotatably connected to the opposite side wall of the fixing base plate 1. The outer wall of the fixing shaft 802 is rotatably connected to a limiting rod 809, wherein the cross-section of the limiting rod 809 is a concave structure. A pull rod 810 is installed on one side of the limiting guide rod 805 and on the outer wall of the sliding plate 806. One end of the pull rod 810 passes through the mounting plate 801 and extends to the outer wall of the mounting plate 801 where a pull block 811 is installed.

[0027] Based on the above structural features and connection relationships, since the magnet will affect the current of the circuit breaker, the electric control magnet 3 can be turned on to generate magnetism only during disassembly and assembly. At the same time, the strength of the electric control magnet 3 can be adjusted. When the circuit breaker 4 is stuck on the outer wall of the fixed base 2, the magnetism of the electric control magnet 3 can just generate magnetic attraction to the circuit breaker 4. The circuit breaker 4 is fixed by the cooperation of plugging and unplugging installation and magnetic attraction.

[0028] The controller 803 is connected to the electrically controlled magnet 3 via a wire, which powers the device and causes the controller 803 to control the electrically controlled magnet 3 to operate.

[0029] When the circuit breaker of this scheme is easy to assemble, the controller 803 is connected to the electric magnet 3 through the wires and the connection method is electrical connection, so that the device is energized and the controller 803 controls the electric magnet 3 to operate.

[0030] With the iron block 5 located on one side of the electrically controlled magnet 3, when a large number of installations are required, the controller 803 is turned on to operate, so that the controller 803 controls the electrically controlled magnet 3 to generate magnetism. It is only necessary to fix the circuit breaker 4 on the outer wall of the fixed base 2, so that the electrically controlled magnet 3 magnetically attracts the iron block 5. There is no need to hold the circuit breaker 4. The electrically controlled magnet 3 magnetically attracts the circuit breaker 4. Then, the limit rod 809 is moved so that the limit rod 809 rotates on the fixed rotating shaft 802, so that the limit rod 809 is fixed on the outer wall of the circuit breaker 4, which facilitates installation. This solves the problem that the existing circuit breaker assembly is relatively complicated, and it is necessary to hold the circuit breaker by hand and fix it on the mounting frame, which is not very practical.

[0031] Pulling up the pull rod 810 by the pull block 811 causes the pull rod 810 to move the sliding plate 806 to one side, which in turn causes the sliding plate 806 to move the fixing pin 808 to one side. At the same time, the sliding plate 806 causes the limiting guide rod 805 to move, so that the limiting guide rod 805 moves on the inner wall of the mounting hole 804. Simultaneously, the sliding plate 806 compresses the limiting spring 807, aligning the fixing pin 808 with the slot 6. When the pull block 811 is released, the compressed limiting spring 807 rebounds, which in turn pushes the sliding plate 806 to move, so that the sliding plate 806 causes the fixing pin 808 to be inserted into the slot 6 and the limiting slot 7 in sequence for fixing. After fixing, the circuit breaker 4 is installed. When the limiting rod 809 and the fixing pin 808 fix the circuit breaker 4, the controller 803 controls the electric magnet 3 to be de-energized and lose its magnetism.

[0032] When it is necessary to replace circuit breaker 4, simply turn on the switch of controller 803, so that controller 803 controls the electric magnet 3 to generate magnetism, thereby causing the electric magnet 3 to magnetically attract and fix the iron block 5. Then, simply pull up the pull block 811 so that the pull rod 810 drives the sliding plate 806 to one side, which in turn drives the fixing pin 808 to one side, causing the fixing pin 808 to disengage from the slot 6 and the limit slot 7. At the same time, after pulling down the limit rod 809, the maintenance personnel can apply a pulling force to circuit breaker 4. Circuit breaker 4, along with the iron block 5 and the electric magnet 3, loses its fixation, and one or more circuit breakers 4 can be removed. This makes assembly more convenient, thus solving the problem of the complicated steps of replacing the circuit breaker body by opening the limit components one by one, which leads to the fatigue of maintenance personnel.

Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the electrically controlled magnet 3 and controller 803 will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
