A drive cylinder is mounted on the upper shelf and transmits power directly through a drive guide rod, reducing energy loss and friction wear in traditional complex transmission chains and improving the overall efficiency of the mechanism. Furthermore, the cooperation between the transverse guide rod and the movable groove makes the movement trajectory of the operating crank arm more stable.

Description

Technical Field

[0001] This utility model relates to an electrical operating component, specifically to an operating mechanism for a low-voltage MNS cabinet. Background Technology

[0002] The MNS cabinet operating mechanism is suitable for indoor locations. Relying on the low-voltage MNS cabinet, electrical components can be operated. When the operator issues a command, the operating mechanism receives the signal and transmits power to circuit breakers and other switching equipment through the transmission device. During the closing operation, the mechanism drives the contacts to close, connecting the circuit. During the opening operation, the opposite occurs, the contacts open, cutting off the current. Relying on the precise mechanical structure and reliable control system, the reliable opening and closing of electrical equipment in the MNS cabinet is ensured, guaranteeing the stable operation of the power system and meeting the power distribution needs of various industries and businesses.

[0003] The operating mechanism of the MNS cabinet still has some significant drawbacks in practical applications. First, it relies heavily on manual operation. Traditional mechanisms often depend on handles or joysticks, which are inefficient in complex scenarios or with frequent operation and cannot be remotely controlled, increasing labor costs and the risk of misoperation. Second, the degree of electrification is insufficient. Some electric mechanisms suffer from insufficient motor power, low transmission efficiency, or slow response speed, especially prone to jamming and failure under high loads or extreme environments, reducing equipment reliability and maintenance frequency. In addition, there is a prominent contradiction between heat dissipation and sealing. Poor heat dissipation in a sealed cabinet may accelerate component aging, while improving heat dissipation may introduce dust, moisture, and other contaminants, affecting insulation performance, further shortening equipment life and increasing the risk of failure. Utility Model Content

[0004] In order to overcome the inconvenience of operation of existing technologies, this utility model provides an operating mechanism for low-pressure MNS cabinets.

[0005] This utility model is achieved using the following technical solution: an operating mechanism for a low-voltage MNS cabinet, comprising an operating mechanism, which is divided into a left operating plate and a right operating plate, with a transmission space between the left and right operating plates, and a transmission component within the transmission space, comprising a transmission main shaft and a transmission secondary shaft, which are assembled and connected to each other, with a transverse guide rod on the transmission secondary shaft, an operating crank arm on the transverse guide rod, and a switch for opening and closing the circuit breaker on the operating crank arm.

[0006] The transmission space is provided with a shelf, which is divided into an upper shelf and a lower shelf. The upper shelf is provided with a driving component, which is a driving cylinder.

[0007] The drive cylinder on the upper shelf is provided with a drive guide rod, and the drive guide rod is provided with an assembly flange. The transmission spindle and the drive guide rod are bolted together by means of the assembly flange.

[0008] An assembly component is provided on one side of the operating mechanism. The assembly component is an assembly plate. The assembly plate is welded and fixed to the operating mechanism. The assembly plate is provided with an assembly groove for assembly.

[0009] The assembly slot is provided with a movable space, and a movable assembly plate is provided in the movable space. The movable assembly plate is provided with assembly holes, and assembly bolts are provided in the assembly holes.

[0010] The right operating panel is provided with a movable groove, from which a horizontal guide rod extends, and the horizontal guide rod moves within the movable groove.

[0011] Compared to existing technologies, the operating mechanism for low-voltage MNS cabinets in this invention achieves precise control of the switch through the assembly connection of the main transmission shaft and the secondary transmission shaft, combined with the linkage design of the transverse guide rod and the operating crank arm. The drive cylinder, as the core driving component, is bolted to the main transmission shaft via the drive guide rod, efficiently transmitting pneumatic power to the transmission system. This drives the transverse guide rod to move smoothly within the movable slot on the right operating plate, thereby actuating the operating crank arm to complete the opening and closing operation of the switch. This structure not only ensures the reliability of the mechanical transmission but also allows for flexible adaptation to the operating force requirements of different electrical switches by adjusting the air pressure or stroke of the drive cylinder, ensuring rapid response and accurate positioning of the switching action. The drive cylinder is mounted on the upper shelf and transmits power directly through the drive guide rod, reducing energy loss and frictional wear in traditional complex transmission chains and improving the overall efficiency of the mechanism. Simultaneously, the cooperation between the transverse guide rod and the movable slot makes the movement trajectory of the operating crank arm more stable.

[0012] The adjustable design of the movable assembly plate within the assembly slot further enhances the structural strength and versatility of the mechanism. The combination of assembly holes and assembly bolts allows users to flexibly adjust the position of the movable assembly plate according to actual installation needs, which not only reduces the difficulty of installation and maintenance but also enables the operating mechanism to be adapted to various models of low-voltage MNS cabinets, meeting the needs of electrical component switching in different scenarios and providing a solid guarantee for the stable operation of the power system.

[0021] By assembling and connecting the main drive shaft 4 and the secondary drive shaft 5, and combining the linkage design of the transverse guide rod 6 and the operating crank arm 7, precise control of the switch is achieved. The drive cylinder 11, as the core drive component, is bolted to the main drive shaft 4 via the drive guide rod 12, efficiently transmitting pneumatic power to the transmission system.

This structure not only ensures the reliability of the mechanical transmission but also allows for flexible adaptation to the operating force requirements of different electrical switches by adjusting the air pressure or stroke of the drive cylinder, ensuring rapid response and accurate positioning of the switching action. The drive cylinder 11 is mounted on the upper support plate 9 and directly transmits power through the drive guide rod 12, reducing energy loss and friction wear in traditional complex transmission chains and improving the overall efficiency of the mechanism.

This not only reduces the difficulty of installation and maintenance, but also enables the operating mechanism to be adapted to various models of low-voltage MNS cabinets, meeting the needs of electrical component switching in different scenarios, and providing a solid guarantee for the stable operation of the power system.
