Description

Technical Field

[0001] This utility model relates to the field of frequency converter technology, specifically to a control mechanism for frequency converter output. Background Technology

[0002] A frequency converter (VFD) is a power control device that controls an AC motor by changing the frequency of the power supply. A VFD mainly consists of a rectification unit (AC to DC), a filter, an inverter (DC to AC), a braking unit, a drive unit, a detection unit, and a microprocessor unit. The VFD adjusts the voltage and frequency of the output power supply by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, VFDs have many protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous improvement of industrial automation, VFDs have been widely used.

[0003] Existing frequency converter control devices require connection to communication lines during use. Currently, when connecting frequency converter control devices to communication lines, they are usually fixed by the pulling force between the connector and the interface on the line. After long-term plugging and unplugging, the pulling force weakens, and the line is prone to separation from the interface, affecting the stability of use. Therefore, a control mechanism for frequency converter output is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a control mechanism for inverter output, which has advantages such as easy separation of communication lines. It solves the problem that when the inverter control device is connected to the communication line, it usually relies on the pulling force between the connector and the interface on the line to achieve fixation. After long-term plugging and unplugging, the pulling force weakens, the line is easy to separate from the interface, and the stability of use is affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control mechanism for inverter output, comprising an inverter control mechanism body, wherein a communication interface is provided on the inverter control mechanism body, and a limit component is provided on the outside of the communication interface;

[0006] The limiting component includes a fixed base disposed on the upper side of the communication interface, a limiting plate disposed on the lower side of the fixed base, an adjusting block extending to the outer side of the fixed base being fixedly connected to the outer wall of the limiting plate, a spring disposed at the upper end of the limiting plate, a wire-passing port being provided at the lower end of the limiting plate, two fixing plates being fixedly installed on the outer wall of the fixed base, a movable shaft being rotatably mounted between the two fixing plates, and a baffle plate being fixedly installed on the outer wall of the movable shaft.

[0007] Furthermore, mounting plates are fixedly connected to both sides of the inverter control mechanism body, and the mounting plates are provided with multiple mounting holes.

[0008] Furthermore, a heat dissipation vent is provided on the side wall of the inverter control mechanism body.

[0009] Furthermore, the fixed base is fixedly installed on the outer wall of the inverter control mechanism body, the upper end of the limiting plate extends into the interior of the fixed base, and the lower end of the limiting plate corresponds to the communication interface.

[0010] Furthermore, the outer wall of the fixed base is provided with a movable opening, and the adjusting block passes through the inner side of the movable opening.

[0011] Furthermore, the spring is located inside the fixed base, with its lower end fixedly connected to the upper end of the limiting plate and its upper end fixedly connected to the interior of the fixed base.

[0012] Furthermore, an adjustment knob is fixedly connected to the upper end of the movable shaft, and the adjustment knob is located on the upper side of the fixed base.

[0013] Furthermore, sliders are fixedly connected to both sides of the limiting plate, and the sliders are slidably connected inside the fixed base. The fixed base is provided with a sliding groove that matches the slider.

[0014] Compared with the prior art, this utility model provides a control mechanism for inverter output, which has the following advantages:

[0015] The control mechanism for the inverter output uses an adjusting block to push a limit plate upwards, compressing a spring. A rotating baffle moves the limit plate below the adjusting block, limiting its position and preventing the spring from automatically resetting the limit plate. This ensures the limit plate doesn't obstruct the communication interface. The connector on the communication line is then connected to the communication interface. Rotating the baffle away from the adjusting block causes the spring to reset the limit plate downwards, bringing it close to the outside of the connector. This limits the connector, preventing the communication line from easily separating from the communication interface. This provides excellent anti-disconnection performance and ensures the stability of the connection. It solves the problem that current inverter control devices, when connected to communication lines, typically rely on the pull-out force between the connector and the interface for fixation. However, after repeated insertions and removals, this pull-out force weakens, causing the line to easily separate from the interface and affecting operational stability. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 4 This embodiment provides a control mechanism for inverter output, including an inverter control mechanism body 1. The inverter control mechanism body 1 has a communication interface 2 for connection with a connector 17 on a communication line 16. A limit component is provided on the outer side of the communication interface 2. The limit component includes a fixing seat 3 on the upper side of the communication interface 2, which is fixedly mounted on the outer wall of the inverter control mechanism body 1. A limit plate 4 is provided on the lower side of the fixing seat 3, with its upper end extending into the interior of the fixing seat 3. An adjusting block 5 extending to the outer side of the fixing seat 3 is fixedly connected to the outer wall of the limit plate 4. A spring 6 is provided at the upper end of the limit plate 4, and a wire-passing port 8 is provided at the lower end of the limit plate 4.

[0023] The fixed base 3 has a movable opening 7 on its outer wall. The adjusting block 5 passes through the inner side of the movable opening 7, allowing the adjusting block 5 to move up and down easily. The lower end of the limiting plate 4 corresponds to the communication interface 2. When the connector 17 on the communication line 16 is engaged with the communication interface 2, the limiting plate 4 is close to the outer side of the connector 17, which can limit the connector 17. The wire passage 8 at the lower end of the limiting plate 4 allows the communication line 16 to pass through the limiting plate 4 easily, ensuring a stable connection of the line. The spring 6 is located inside the fixed base 3. The lower end of the spring 6 is fixedly connected to the upper end of the limiting plate 4, and the upper end of the spring 6 is fixedly connected to the inside of the fixed base 3. The spring 6 can achieve elastic adjustment of the position of the limiting plate 4. Slider 9 is fixedly connected to both sides of the limiting plate 4. The slider 9 is slidably connected inside the fixed base 3. The inside of the fixed base 3 is provided with a sliding groove that matches the slider 9, so that the limiting plate 4 can maintain stable up and down movement.

[0024] In this embodiment, two fixing plates 10 are fixedly installed on the outer wall of the fixed base 3. A movable shaft 11 is rotatably installed between the two fixing plates 10. A baffle 12 is fixedly installed on the outer wall of the movable shaft 11. An adjustment knob 13 is fixedly connected to the upper end of the movable shaft 11 and is located on the upper side of the fixed base 3. When the adjusting block 5 is pushed to move the limiting plate 4 upward, the limiting plate 4 presses the spring 6 upward. By rotating the adjustment knob 13, the movable shaft 11 is rotated, thereby driving the baffle 12 to rotate. By rotating the baffle 12, it is moved below the adjusting block 5, thereby limiting the adjusting block 5 and temporarily preventing the spring 6 from automatically resetting the limiting plate 4.

[0025] In addition, mounting plates 15 are fixedly connected to both sides of the inverter control mechanism body 1. The mounting plates 15 are provided with multiple mounting holes for mounting the inverter control mechanism body 1. Heat dissipation vents 14 are provided on the side walls of the inverter control mechanism body 1 to provide ventilation and heat dissipation.

[0026] The working principle of the above embodiments is as follows:

[0027] In use, push the adjusting block 5 to drive the limiting plate 4 to press the spring 6 upward. Rotate the adjusting knob 13 to drive the movable shaft 11 to rotate, thereby driving the baffle 12 to rotate. By rotating the baffle 12, move it below the adjusting block 5 to limit it, preventing the spring 6 from automatically resetting the limiting plate 4, so that the limiting plate 4 will not block the communication interface 2. Then connect the connector 17 on the communication line 16 to the communication interface 2. Rotate the baffle 12 to move it away from the adjusting block 5. The spring 6 will then reset the limiting plate 4 downward, so that the limiting plate 4 is close to the outside of the connector 17, thereby limiting the connector 17 and making it difficult for the communication line 16 and the communication interface 2 to separate.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
