Description

Technical Field

[0001] This utility model relates to the technical field of alarm devices for control cabinets, and in particular to a novel fixing structure for alarm devices for control cabinets. Background Technology

[0002] In the process of modern industrial automation, control cabinets, as the core hub of electrical systems, undertake the important task of centralized control, monitoring, and protection of various electrical equipment. To ensure the stable operation of control cabinets and timely detection of potential faults, the installation and securing of alarm devices become crucial. Alarm devices can monitor fault signals such as abnormal temperature, circuit overload, and gas leaks in real time, and the reliability of their mounting structure directly affects the safety and stability of equipment operation. With the increasing complexity of industrial scenarios, higher demands are placed on the convenience, flexibility, and adaptability of alarm device mounting structures. Traditional mounting methods are no longer sufficient to meet diverse needs, necessitating innovative designs.

[0003] Currently, common control cabinet alarm device fixing structures mostly employ mechanical methods such as screw fastening and clip-on nesting. Screw fastening involves directly fixing the alarm device to the pre-set mounting holes in the control cabinet using screws. This method relies on the friction between the threads to achieve fixation, and the pressure generated by tightening the nut secures the device to the cabinet. Clip-on nesting involves setting matching clips and slots on both the cabinet and the alarm device. The device is fixed by the clips engaging the slots. The principle is based on the elastic deformation of the clips and the limiting effect of the slots to keep the device stable. These structures, with their simple mechanical principles, achieve the function of fixing alarm devices to a certain extent.

[0004] However, existing fixing structures have revealed significant drawbacks in practical applications. When installing, disassembling, or adjusting the position of alarm devices, screw tightening requires multiple tools such as screwdrivers and wrenches, making the operation cumbersome and time-consuming. Repeated disassembly and assembly can also lead to problems such as stripped screws and wear on cabinet mounting holes. While snap-fit ​​structures do not require tools, they often have a single fixed size, making it difficult to adapt to different specifications of alarm devices. Forced installation can damage the device or the snap-fit. Therefore, a new fixing structure for alarm devices in control cabinets is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of fixing structure for alarm devices in control cabinets, which aims to improve the problem that the existing technology requires multiple tools to fix the alarm device, making it difficult to fix it conveniently.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel fixed structure for alarm devices in a control cabinet includes a control cabinet, a sealed door rotatably connected to the outer wall of the control cabinet, a controller fixedly connected inside the control cabinet, and fixed components installed inside the control cabinet.

[0008] The fixing assembly includes an L-shaped clamp, the outer wall of which is disposed inside the control cabinet. A movable plate is fixedly connected to the top of the L-shaped clamp. A connecting plate is disposed inside the control cabinet. A limit assembly is disposed at the bottom of the connecting plate. A fixed plate is fixedly connected to the bottom of the connecting plate. A connecting column is fixedly connected to the bottom of the fixed plate. A rotating rod is rotatably connected to the bottom of the connecting column. A transmission rod is rotatably connected to both sides of the rotating rod. The other side of the transmission rod is rotatably connected to the bottom of the movable plate. An electric push rod is fixedly connected to the top of the movable plate. The output belt of the electric push rod is fixedly connected to the outer wall of the connecting column. The movable assembly is disposed inside the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting post, the top of which is fixedly connected to the bottom of the connecting plate, the inside of which is fixedly connected to the outer wall of the limiting post, and the inside of which is slidably connected to the outer wall of the limiting post.

[0011] As a further description of the above technical solution:

[0012] The moving component includes a connecting plate and a limiting rail, with the connecting plate slidably connected to the outer wall of the limiting rail.

[0013] As a further description of the above technical solution:

[0014] The top of the limiting rail is fixedly connected to the inner wall of the control cabinet, and multiple slots are provided inside the limiting rail.

[0015] As a further description of the above technical solution:

[0016] Both sides of the connecting plate are fixedly connected to a fixed housing, and the fixed housing has a limit groove inside.

[0017] As a further description of the above technical solution:

[0018] The fixed outer shell has a slidingly connected locking post inside, and the outer wall of the locking post is slidably connected inside the locking slot.

[0019] As a further description of the above technical solution:

[0020] The other end of the locking pin is fixedly connected to a limiting disc, the outer wall of the limiting disc is slidably connected to the inside of the limiting groove, and a push plate is fixedly connected to the bottom of the limiting disc.

[0021] As a further description of the above technical solution:

[0022] A spring is provided inside the fixed housing. One end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end of the spring is fixedly connected to the outer wall of the limiting disc.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the L-shaped clamp realizes its movement function by activating the electric push rod. When the electric push rod is activated, the moving plate is driven by the electric push rod and cooperates with the transmission rod and the rotating rod to realize the sliding of the moving plate on the outer wall of the limiting column, thereby conveniently fixing and disassembling the alarm and maintaining its stability. This solves the problem that multiple tools are needed to fix the alarm in the existing way, which makes it difficult to fix it conveniently, and improves the convenience of fixing the alarm.

[0025] 2. In this utility model, the locking column achieves its movement function by pushing the push plate. When the push plate is pushed, the push plate drives the limiting disc and the spring, and cooperates with the limiting groove to realize the sliding of the locking column inside the groove. This allows the connecting plate to slide on the outer wall of the limiting rail, which facilitates accurate detection of different key positions. This solves the problem of not being able to accurately detect the controllers in different positions, and improves the applicability of the detection. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a novel control cabinet for alarm equipment fixing structure, including a control cabinet 1. The control cabinet 1 is a rectangular metal frame structure, made of cold-rolled steel plate bent and welded, and the surface is treated with electrostatic spraying, which has good anti-rust and anti-corrosion performance. It is used to provide a protective space for internal electrical components to avoid damage to the components caused by dust, moisture and external forces. A sealed door 2 is rotatably connected to the outer wall of the control cabinet 1. The edge of the sealed door 2 is embedded with a rubber sealing strip, which can form a sealed space when closed to prevent external dust and moisture from entering the cabinet and affecting the normal operation of the alarm equipment. A controller 4 is fixedly connected inside the control cabinet 1, and a fixing component is set inside the control cabinet 1.

[0035] The fixing assembly includes an L-shaped clamp 3, which is welded from two mutually perpendicular metal plates. Made of steel with a nickel-plated surface to enhance wear resistance and oxidation resistance, the L-shaped clamp 3 is used to clamp and fix the alarm device from both sides, preventing it from shaking or shifting during operation. The outer wall of the L-shaped clamp 3 is located inside the control cabinet 1. A movable plate 9 is fixedly connected to the top of the L-shaped clamp 3. A connecting plate 7 is located inside the control cabinet 1. A limit component is located at the bottom of the connecting plate 7. A fixing plate 10 is fixedly connected to the bottom of the fixing plate 10. A connecting column 14 is fixedly connected to the bottom of the connecting column 14. A rotating rod 12 is rotatably connected to both sides of the rotating rod 12. There is a transmission rod 13, and the other side of the transmission rod 13 is rotatably connected to the bottom of the moving plate 9. An electric push rod 11 is fixedly connected to the top of the moving plate 9. The output of the electric push rod 11 is fixedly connected to the outer wall of the connecting column 14. A moving component is set inside the connecting plate 7. The limiting component includes a limiting column 8. The limiting column 8 is a cylindrical solid structure made of No. 45 steel. The surface is quenched and the hardness reaches HRC45. The top is fixedly connected to the bottom of the connecting plate 7 by welding. A through hole matching the limiting column 8 is opened inside the fixed plate 10. It is fixedly connected to the outer wall of the limiting column 8 by interference fit. A sliding groove is opened inside the moving plate 9. It is slidably connected to the outer wall of the limiting column 8. The limiting post 8 slides linearly with the sliding groove of the moving plate 9, thereby limiting the moving direction of the moving plate 9 and ensuring that it moves along a fixed trajectory, thus ensuring the smooth movement of the L-shaped clamp 3. The top of the limiting post 8 is fixedly connected to the bottom of the connecting plate 7, the inside of the fixed plate 10 is fixedly connected to the outer wall of the limiting post 8, and the inside of the moving plate 9 is slidably connected to the outer wall of the limiting post 8.

[0036] Specifically, when the alarm needs to be fixed, the operator activates the electric push rod 11 via the control button on the control panel. The electric push rod 11 is driven by a servo motor, and its output shaft is rigidly connected to the connecting column 14 via a high-strength coupling to ensure stable power transmission. When the electric push rod 11 extends, the resulting linear thrust drives the bottom moving plate 9 to slide to both sides against the outer wall of the limiting column 8. The surface of the limiting column 8 is precision ground, and in conjunction with the linear bearing built into the moving plate 9, effectively reduces running resistance. During the sliding process of the moving plate 9, the transmission rod 13, connected by a hinge, rotates accordingly. The transmission rod 13 and the rotating rod 12 form a four-bar linkage, using the lever principle to convert linear motion into rotational motion. When one side of the transmission rod 13 rotates, it drives the rotating rod 12 to rotate synchronously, thereby driving the other side of the transmission rod 13 to rotate in the opposite direction, achieving synchronous reverse movement of the two moving plates 9. This design ensures that the two L-shaped clamps 3 always maintain symmetrical movement, allowing for precise positioning of alarms of different sizes. After the alarm is placed between the two L-shaped clamps 3, the operator presses the control button again, and the electric push rod 11 retracts. As the electric push rod 11 shortens, the two L-shaped clamps 3 gradually converge towards the center, and the anti-slip rubber pads on their inner sides fit tightly against the alarm housing. At the same time, the pressure sensor built into the control system monitors the clamping force in real time. When the preset threshold is reached, the electric push rod 11 automatically stops, ensuring that the alarm will not shift due to excessively loose clamping or damage to the housing due to excessively tight clamping during the fixing process, thus achieving a stable and reliable fixing effect.

[0037] Reference Figure 3 and Figure 5 The moving component includes a connecting plate 7 and a limiting rail 5. The connecting plate 7 is slidably connected to the outer wall of the limiting rail 5. The limiting rail 5 is a T-shaped metal guide rail made of high-strength aluminum alloy, which is lightweight, corrosion-resistant, and wear-resistant. The top of the limiting rail 5 is fixedly connected to the inner wall of the control cabinet 1. The limiting rail 5 has multiple slots 6 inside. Fixed housings 15 are fixedly connected to both sides of the connecting plate 7. The fixed housings 15 have limiting grooves 20 inside. Locking posts 17 are slidably connected inside the fixed housings 15. The locking posts 17 are cylindrical solid. The core structure is made of alloy structural steel. Its outer wall can be tightly embedded in the slot 6 of the limiting rail 5 to lock the position of the connecting plate 7. The outer wall of the locking post 17 is slidably connected to the inside of the slot 6. The other end of the locking post 17 is fixedly connected to the limiting disc 18. The outer wall of the limiting disc 18 is slidably connected to the inside of the limiting groove 20. The bottom of the limiting disc 18 is fixedly connected to the push plate 19. The fixed outer shell 15 is equipped with a spring 16. One end of the spring 16 is fixedly connected to the inner wall of the limiting groove 20, and the other end of the spring 16 is fixedly connected to the outer wall of the limiting disc 18.

[0038] Specifically, when testing the controller 4 in different positions, the operator holds the push plate 19 and applies force to one side. The push plate 19 features an anti-slip texture design to ensure it is not slippery during operation. As the push plate 19 moves, the limiting disc 18, which is rigidly connected to it, slides synchronously within the limiting groove 20. The limiting groove 20 is made of high-hardness stainless steel, and its walls are hardened to effectively prevent wear caused by long-term sliding. The movement of the limiting disc 18 causes the locking pin 17 to gradually slide out of the locking groove 6, while simultaneously compressing the spring 16 sleeved on the locking pin 17. The connecting plate 7 is freed from the limiting constraint of the locking pin 17 and can slide freely along the outer wall of the limiting rail 5. When the connecting plate 7 slides to the appropriate position, the operator releases the push plate 19. The compressed spring 16 quickly rebounds, pushing the locking pin 17 back into the locking groove 6, achieving rapid positioning and locking of the connecting plate 7. This ensures the alarm remains stable in the new position, thereby achieving accurate testing of the controller 4.

[0039] Working principle: When the alarm needs to be fixed, the electric push rod 11 is activated. The output belt of the electric push rod 11 is connected to the connecting column 14. When it extends, it drives the moving plate 9 at the bottom of the electric push rod 11 to slide to both sides on the outer wall of the limiting column 8. Then, the moving plate 9 drives the bottom transmission rod 13 to rotate, which in turn drives the rotating rod 12 to rotate, thereby rotating the other side transmission rod 13 and moving the other side moving plate 9. This causes the two L-shaped clamps 3 to move to both sides to place the alarm. Then, the electric push rod 11 is retracted, and the L-shaped clamps 3 are gathered in the middle to fix the alarm and keep it stable.

[0040] In addition, when the controller 4 is tested in different positions, the push plate 19 can be pushed to move, and then the push plate 19 drives the limiting disc 18 to slide inside the limiting groove 20, thereby driving the locking pin 17 to slide out from inside the locking groove 6 and compressing the spring 16, so that the connecting plate 7 can slide on the outer wall of the limiting rail 5. After reaching the appropriate position, the push plate 19 is released, and the spring 16 rebounds to drive the locking pin 17 back to its original position to fix it and maintain stability, thereby adjusting the position of the alarm and accurately testing it.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
