Description

Technical Field

[0001] This utility model relates to the field of automatic control technology, and in particular to a compact U-rail mounted PID controller structure. Background Technology

[0002] The compact U-rail mounted PID controller, through the coordinated action of its three control elements (proportional (P), integral (I), and derivative (D), calculates the appropriate control input based on the current system deviation and its rate of change and integral. This allows for precise adjustment of the controlled object, enabling the system output to quickly and accurately track the setpoint. For example, in a temperature control system, it can precisely control the temperature near the set value. The compact U-rail mounting method makes the controller's installation in control cabinets and other spaces neater and more compact, saving installation space. It also facilitates installation and disassembly, simplifying future maintenance and repair.

[0003] The compact U-rail mounted PID controller integrates a PID algorithm with a compact mounting structure, achieving precise closed-loop control of industrial system parameters. It combines flexibility, stability, and ease of installation, making it a key component for efficient and reliable control in industrial automation. Its core value lies in balancing system response speed, stability, and anti-interference capabilities through algorithm optimization and hardware design, meeting the precise control needs of various scenarios.

[0004] In existing technologies, during equipment maintenance or repair, the inability to quickly disassemble PID controllers requires technicians to spend more time removing related components, increasing maintenance difficulty and cost. If the controller malfunctions, it leads to prolonged equipment downtime, impacting production efficiency. When upgrading or replacing the PID controller with a more advanced model, the lack of a quick-disassembly function complicates the process, requiring damage to the original installation structure or the use of special tools, increasing the difficulty and risk of upgrades. Furthermore, during installation, if the controller's position needs to be adjusted, or if it needs to be reused in different equipment or systems, the inconvenience of disassembly limits its installation flexibility and reduces its efficiency. Therefore, a compact U-rail mounted PID controller structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a compact U-rail mounted PID controller structure, which aims to improve the problems of inconvenient maintenance and repair, difficult upgrading and modification, and reduced installation flexibility in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A compact U-shaped guide rail mounted PID controller structure includes a square box.

As a further description of the above technical solution: The shock absorption assembly includes multiple fixed plates three, the bottom ends of the multiple fixed plates three are fixedly connected to the top of the square box, the left and right sides of the multiple fixed plates three are fixedly connected to support plates one, the interior of the multiple fixed plates three is slidably connected to support plates two, the far sides of the two support plates two are fixedly connected to spring two, and the near sides of the two support plates two are fixedly connected to fixing blocks. As a further description of the above technical solution: Both of the fixed blocks have connecting rods slidably connected inside, and both connecting rods have mounting plates fixedly connected to their top ends; As a further description of the above technical solution: Each of the mounting plates is fixedly connected to a differential controller at its top, and the bottom of the square box is slidably connected to a U-shaped guide rail. As a further description of the above technical solution: The other ends of the two springs are fixedly connected to the adjacent sides of the two connecting plates, and the outer walls of the two connecting plates are slidably connected to the inside of the square box.

As a further description of the above technical solution: The fixed plate three has a sliding groove inside, and the bottom ends of the multiple support plates one are fixedly connected to the top of the square box.

[0007] This utility model has the following beneficial effects: 1. In this utility model, pressing the connecting plate one causes the connecting plate two and the fixing plate two to move inside the square box, achieving quick disassembly. With technological advancements or improvements in production processes, it may be necessary to upgrade or replace the PID controller with a more advanced model. The quick disassembly feature makes these operations more convenient, eliminating the need for complex disassembly processes and allowing for rapid replacement of old and new controllers to meet system upgrade and modification needs. For operators, the quick disassembly design makes controller installation and removal simpler and easier, requiring no special tools or complex operating skills, reducing the risk of equipment damage or insecure installation due to improper operation.

[0008] 2. In this utility model, the support plate slides inside the fixed plate by pressing the mounting plate, achieving a shock absorption effect. In industrial environments, equipment may be affected by various vibration sources, such as the operation of nearby machines and ground vibration. The shock absorption design of the compact U-rail mounted PID controller can effectively reduce the impact of these external vibrations on the precision electronic components inside the controller, preventing damage, desoldering, or poor contact due to vibration, thereby extending the service life of the controller and improving its operational stability and reliability. For example, in factories with large machinery operating, if the PID controller does not have good shock absorption measures, long-term vibration may damage its internal chips, capacitors, and other components, while the shock absorption design can greatly reduce this risk.

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.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of a compact U-shaped guide rail mounted PID controller structure, including a square box 1, which serves as the main structure of the entire device. The square box 1 plays the role of supporting and protecting the internal components. A fixing plate 2 is fixedly connected inside the square box 1. The fixing plate 2 is fixedly connected inside the square box 1, and its main function is to provide a stable mounting base for the spring 3. The fixing plate 2 is fixedly connected to the left and right sides of the fixing plate 3. The fixing plate 2 provides stability for the spring 3 and provides a reset function for the connecting plate 4. The square box 1 is slidably connected to the left and right sides of the inside of the square box 1. The square box 1 provides a limiting and guiding function for the connecting plate, and the rear end is connected to the spring 3 to provide a reset function for it.

[0013] Two connecting plates 4 are fixedly connected to the bottom of their adjacent sides. The bottom of the two connecting plates 4 is fixed to the bottom of their adjacent sides. The function of the connecting plates 4 is to connect the connecting plates 4 and the fixed plates 6, and to transmit the force from the connecting plates 4 to the fixed plates 6, so as to drive the fixed plates 6 to move. The bottom of the two connecting plates 5 is fixedly connected to the fixed plates 6. The connecting plates 5 provide stability to the fixed plates 6 and ensure the stable operation of the hollow column 7 inside. The hollow column 7 is rotatably connected inside the two fixed plates 6. The fixed plates 6 provide installation space, stability and limit effect for the hollow column 7. The roller 8 is rotatably connected inside the hollow column 7. The hollow column 7 provides stability to the roller 8 and ensures the smooth operation of the roller 8 inside the U-shaped guide rail 17. Multiple shock-absorbing components are installed on the top of the square box 1 to protect the differential controller 16. Reference Figures 3 to 4 The shock absorption assembly includes multiple fixed plates 3 9. The fixed plates 3 9 provide installation space and guidance for subsequent components, preventing shaking during operation. The bottom ends of the multiple fixed plates 3 9 are fixedly connected to the top of the square box 1. The square box 1 provides stability for the fixed plates 3 9, allowing the shock absorption assembly to operate stably when the square box 1 is moved. Support plates 1 10 are fixedly connected to the left and right sides of the multiple fixed plates 3 9. The fixed plates 3 9 provide stability for the support plates 1 10, and the support plates 1 10 provide support for the internal components.

[0014] Multiple fixed plates 3 9 are internally slidably connected to support plates 2 11. Fixed plates 3 9 provide guidance for support plates 2 11 to prevent deviation during operation. Two springs 2 12 are fixedly connected to the far sides of the two support plates 2 11. Springs 2 12 provide cushioning when support plates 2 11 shake, reducing the impact force transmitted to other components. Two fixed blocks 13 are fixedly connected to the near sides of the two support plates 2 11. Support plates 2 11 provide stability for fixed blocks 13 and for the connecting rods 14 that are rotated inside fixed blocks 13, preventing shaking and deviation. Reference Figures 2 to 4 Both fixed blocks 13 have connecting rods 14 slidably connected inside. The fixed blocks 13 ensure that the connecting rods 14 maintain the accuracy and stability of the direction during rotation, preventing shaking or deviation. The tops of both connecting rods 14 are fixedly connected to mounting plates 15. The connecting rods 14 transmit the shaking of the differential controller 16 through the connection with the mounting plates 15. The tops of multiple mounting plates 15 are fixedly connected to the differential controller 16. The mounting plates 15 provide a stable mounting platform for the differential controller 16, maintain stability during operation, and provide a shock absorption effect. The bottom of the square box 1 is slidably connected to a U-shaped guide rail 17. The shape design of the U-shaped guide rail 17 provides precise guidance for the movement of the device and provides a limiting and guiding function for the square box 1.

[0015] The other ends of the two springs 3 are fixedly connected to the adjacent sides of the two connecting plates 4. The springs 3 provide buffering and reset for the connecting plates 4, ensuring stable operation and state recovery. The outer walls of the two connecting plates 5 are slidably connected to the inside of the square box 1. The square box 1 provides limiting and guiding functions for the connecting plates 5, preventing shaking and deviation during operation. The outer wall of the roller 8 is slidably connected to the inner wall of the U-shaped guide rail 17. The outer wall of the roller 8 is slidably connected to the inner wall of the U-shaped guide rail 17. Its main function is to convert the sliding friction between the device and the U-shaped guide rail 17 into rolling friction, which greatly reduces the friction force when the device moves, reduces energy loss, and enables the entire device to move more smoothly and efficiently on the U-shaped guide rail 17. The outer walls of the two connecting plates 5 are slidably connected to the inner wall of the U-shaped guide rail 17. The connecting plates 5 slide on the inner wall of the U-shaped guide rail 17 to ensure the stability and accuracy of the device's movement on the guide rail.

[0016] The square box 1 has sliding grooves at both ends. The sliding grooves inside the square box 1 provide limiting and guiding functions for the connecting plate 1 4 and the connecting plate 2 5. The other ends of the two springs 2 12 are fixedly connected to the adjacent side of the support plate 1 10. The support plate 1 10 provides installation space and stability for the springs 2 12. The sliding groove inside the fixing plate 3 9 provides guiding and limiting functions for the support plate 2 11. The bottom ends of the multiple support plates 1 10 are fixedly connected to the top of the square box 1. The square box 1 provides stability for the support plates 1 10 and prevents the shock absorption components from shaking during operation.

[0017] Working Principle: When installing the compact U-rail mounted PID controller, align the square box 1 with the U-rail. The U-rail presses against the connecting plates 4 on both sides, causing the connecting plates 4 to slide within the square box 1, compressing the springs 3 on both sides of the fixing plate 2. The springs 3 provide buffering and restoring force. The connecting plate 4 drives the connecting plate 5 and the fixing plate 6 to move, causing the hollow column 7 rotatably connected within the fixing plate 6 and the roller 8 rotatably connected within the hollow column 7 to contact the U-rail. The roller 8 can roll along the U-rail, facilitating the sliding adjustment of the controller on the U-rail. After installation, the elasticity of the spring 3 pushes the connecting plate 4, causing the roller 8 to fit tightly against the U-rail, achieving a stable installation of the controller. Furthermore, the elasticity of the spring 3 adapts to different sized U-rails, ensuring the universality and convenience of installation.

[0018] When the compact U-rail mounted PID controller is subjected to external vibration, the vibration damping components come into play. Multiple fixed plates 9 at the top of the square box 1 serve as a support base, and the support plates 10 on the left and right sides enhance the structural stability. When vibration is transmitted, the mounting plate 15 drives the two connecting rods 14 to slide within the fixed block 13, causing the support plate 11 to move up and down within the fixed plate 9, thereby compressing or stretching the spring 12. The spring 12 absorbs and buffers the vibration energy through its own elastic deformation, reducing the impact of vibration on the controller. The sliding of the support plate 11 within the fixed plate 9 and the sliding of the connecting rods 14 within the fixed block 13 ensure the smoothness and guidance of the vibration damping process. Ultimately, through the coordinated operation of the vibration damping components, the impact of external vibration on the internal components of the controller mounted on the mounting plate 15 is effectively reduced, improving the stability and service life of the controller.
