Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a multifunctional intelligent molded case circuit breaker. Background Technology

[0002] In the field of circuit breaker technology, the installation process of traditional molded case circuit breakers has long faced many problems that urgently need to be solved, becoming a key factor restricting installation efficiency and operational stability.

[0003] Traditional molded case circuit breakers (MCCBs) are typically connected to their mounting bases using direct bolt fixing. This requires precise alignment of the bolt holes, a cumbersome process that consumes significant manpower and time. This is especially problematic in confined electrical cabinet spaces, where bolt tightening and positioning become extremely difficult, severely reducing overall assembly efficiency. While some circuit breakers utilize a sliding rail system, offering easier initial positioning, they lack reliable limiting and fixing structures. Relying solely on the friction between the rail and the slider for fixation, they are susceptible to displacement under external vibrations or impacts, compromising post-installation stability and potentially affecting circuit connection reliability. Furthermore, traditional circuit breaker mounting components lack automatic reset functionality. Adjusting and fixing limiting components requires continuous manual operation, resulting in low automation. After installation, the sliding structure of the slider and rail is directly exposed, easily accumulating dust and debris. This not only hinders disassembly and adjustment during subsequent maintenance but can also damage the sliding structure due to obstruction, shortening the circuit breaker's lifespan.

[0004] To address this issue, we propose a multifunctional intelligent molded case circuit breaker. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional intelligent molded case circuit breaker that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional intelligent molded case circuit breaker, comprising: Circuit breaker body; A mounting plate is disposed on the back of the circuit breaker body. A guide rail is fixedly mounted on the front of the mounting plate. A slider is slidably disposed on the side wall of the guide rail. The front of the slider is fixedly mounted to the back of the circuit breaker body. A mounting assembly is provided between the slider and the mounting plate.

[0007] Preferably, the mounting components include: U-shaped plate, fixedly installed on the front of the mounting plate; A cylindrical rod is inserted through the U-shaped plate, and the cylindrical rod can rotate relative to the U-shaped plate; The limiting blocks are fixedly installed in pairs and parallel on the outer wall of the column rod. The lower end of the limiting block is in contact with the side of the slider, and the upper end of the limiting block is in contact with the side of the U-shaped plate.

[0008] Preferably, a torsion spring is sleeved on the outer wall of the middle part of the column rod, and the two ends of the torsion spring are fixedly installed on the inner wall of the U-shaped plate. The elastic force of the torsion spring can make the column rod automatically reset, so that the limiting block always maintains the contact limiting state with the slider, thereby improving the stability and automation of the installation component.

[0009] Preferably, the end of the cylindrical rod is fixedly fitted with an anti-slip sleeve, and there are two anti-slip sleeves. The two anti-slip sleeves at the end of the cylindrical rod can increase the friction of the operator's hand when rotating the cylindrical rod, making it easy to control the rotation of the cylindrical rod, while preventing the hand from slipping, thus improving the convenience and safety of operation.

[0010] Preferably, the top surface of the slider is provided with a protective plate, and the protective plate is slidably configured with a groove on the front side of the mounting plate. The protective plate on the top surface of the slider and the groove of the mounting plate slide together, which can protect the slider and the circuit breaker body and reduce the impact of external dust, debris and other objects on the slider sliding structure.

[0011] Preferably, the part of the guard plate that slides with the groove is made of rubber. Rubber has good elasticity and wear resistance, which can enhance the friction when the guard plate slides and prevent it from sliding easily.

[0012] Preferably, a pair of parallel L-shaped plates are fixedly installed on the surface of the protective plate. The pair of parallel L-shaped plates on the surface of the protective plate can further enhance the structural strength of the protective plate and improve its aesthetics.

[0013] This utility model provides a multifunctional intelligent molded case circuit breaker. This multifunctional intelligent molded case circuit breaker has the following advantages: 1. This multi-functional intelligent molded case circuit breaker, after rotating the cylindrical rod to drive the limit block to rotate, uses the sliding cooperation between the guide rail and the slider to complete the position adjustment of the circuit breaker body. After releasing the cylindrical rod, the elastic force of the torsion spring causes the limit block to reset and lock the slider, realizing the stable installation of the circuit breaker body.

[0014] 2. This multi-functional intelligent molded case circuit breaker pushes the guard plate along the slide groove to cover the top surface of the slider, which can block the influence of dust and debris on the sliding structure. The L-shaped plate on the surface of the guard plate strengthens the structural strength of the guard plate and also improves the overall aesthetics. Attached Figure Description

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, this utility model provides a technical solution: a multifunctional intelligent molded case circuit breaker, comprising: Circuit breaker body 1; Mounting plate 2 is located on the back of circuit breaker body 1. A guide rail 4 is fixedly mounted on the front of mounting plate 2. A slider 3 is slidably mounted on the side wall of guide rail 4. The front of slider 3 is fixedly mounted to the back of circuit breaker body 1. There is a mounting assembly between slider 3 and mounting plate 2. The installation components include: U-shaped plate 8 is fixedly installed on the front of mounting plate 2; The column rod 9 is inserted through the U-shaped plate 8, and the column rod 9 can rotate relative to the U-shaped plate 8; Here, the U-shaped plate 8, the column rod 9 and the limiting block 10 work together to limit the slider 3 connected to the circuit breaker body 1, stabilize the position of the circuit breaker body 1 on the mounting plate 2, and realize the rapid positioning and installation of the circuit breaker body 1. Among them, a torsion spring 11 is sleeved on the outer wall of the middle part of the column rod 9. The two ends of the torsion spring 11 are fixedly installed on the inner wall of the U-shaped plate 8. The elastic force of the torsion spring 11 can make the column rod 9 automatically reset, so that the limit block 10 always maintains the contact limit state with the slider, thereby improving the stability and automation of the installation components. Furthermore, the end of the column rod 9 is fixedly fitted with an anti-slip sleeve 12. There are two anti-slip sleeves 12. The two anti-slip sleeves 12 at the end of the column rod 9 can increase the friction of the operator's hand when rotating the column rod 9, making it easy to control the rotation of the column rod 9. At the same time, it can prevent the hand from slipping, improving the convenience and safety of operation. Limiting blocks 10 are fixedly installed in pairs and in parallel on the outer wall of the column rod 9. The lower end of the limiting block 10 is in contact with the side of the slider 3, and the upper end of the limiting block 10 is in contact with the side of the U-shaped plate 8.

[0019] The top surface of the slider 3 is in contact with a protective plate 7. The protective plate 7 is slidably connected to the groove 6 opened on the front of the mounting plate 2. The protective plate 7 on the top surface of the slider 3 and the groove of the mounting plate 2 are slidably engaged, which can protect the slider 3 and the circuit breaker body 1 and reduce the impact of external dust, debris and other objects on the sliding structure of the slider 3. The sliding parts of the guard plate 7 and the slide groove 6 are made of rubber. Rubber has good elasticity and wear resistance, which can enhance the friction when the guard plate 7 slides and prevent it from sliding easily. Pairs of parallel L-shaped plates 5 are fixedly installed on the surface of the guard plate 7. The pairs of parallel L-shaped plates 5 on the surface of the guard plate 7 can further enhance the structural strength of the guard plate 7 and enhance its aesthetics.

[0020] When using this multi-functional intelligent molded case circuit breaker, the cylindrical rod 9 is rotated to drive the pair of parallel limit blocks 10 to rotate synchronously until the arc end of the limit block 10 rotates to the upper position. Then, the guide rail 4 fixed on the front of the mounting plate 2 and the slider 3 fixed on the back of the circuit breaker body 1 form a sliding engagement. Pushing the circuit breaker body 1 will drive the slider 3 to move along the guide rail 4, quickly adjusting the circuit breaker body 1 to the target installation position on the mounting plate 2. At this time, the cylindrical rod 9 is loosened, and under the action of the torsion spring 11, the limit block 10 gradually returns to the initial position and contacts the side of the slider 3. The limiting action of the limit block 10 is used to lock the slider 3, thereby fixing the position of the circuit breaker body 1. Then push the protective plate 7 so that it slides along the groove 6 opened on the front of the mounting plate 2 until the protective plate 7 covers the top surface of the slider 3, which protects the slider 3 and the connection structure between the circuit breaker body 1 and the slider 3, reducing the influence of external dust and debris. The pair of parallel L-shaped plates 5 fixedly installed on the surface of the protective plate 7 can further enhance the structural strength of the protective plate 7 itself, prevent the protective plate 7 from deforming due to external forces during the protection process, and improve the aesthetics of the overall structure.

[0021] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
