Description

Technical Field

[0001] This utility model relates to the field of PLC control cabinet technology, and in particular to a PLC control cabinet with a cable positioning mechanism. Background Technology

[0002] In the field of modern industrial automation, PLC control cabinets, as core control equipment, are widely used in various industries such as power, machinery manufacturing, and chemical industry. The rationality and stability of its internal wiring layout directly affect the reliability, efficiency, and ease of maintenance of the system. Currently, most PLC control cabinets use traditional fixed installation methods for wiring management, with cables usually simply fixed inside the cabinet using cable ties or wire clips.

[0003] An existing authorized publication number (CN222485032U) discloses a PLC automation control cabinet with a cable positioning structure. The cabinet has a base body fixedly connected to its lower outer surface, and internal components are fixedly connected inside the cabinet. A base groove is formed inside the base body. A turntable is nested on the base body, and a first threaded rod is fixedly connected to its lower end. A stabilizing mechanism is provided between the first threaded rod and the base groove. A second threaded rod is nested on the cabinet, and a handle is fixedly connected to its outer end. A movable plate is threaded onto the second threaded rod. The user can pass the cable through the arc-shaped plate. Driven by the elastic force of the return spring, the limiting plate moves the clamping plate via a driving rod until the clamping plate contacts the cable, positioning and clamping it, thus reducing the possibility of cable tangling to a certain extent.

[0004] Regarding the aforementioned technologies, the existing PLC control cabinets have the following drawbacks: when it is necessary to inspect and repair the wiring in a specific area, maintenance personnel have to painstakingly search for fault points in a dense and messy network of wires, lacking an independent maintenance operation space. Therefore, this utility model provides a PLC control cabinet with a wiring positioning mechanism. Utility Model Content

[0005] The purpose of this application is to provide a PLC control cabinet with a cable positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A PLC control cabinet with a cable positioning mechanism includes a housing. A fixed plate is fixedly connected inside the housing. A locking assembly is provided on the top of the fixed plate. The locking assembly includes a fixed frame fixedly connected to the top of the fixed plate. A rotating shaft is rotatably connected to the side wall of the fixed frame. A deflecting rod is fixedly connected to the side wall of the rotating shaft. A locking block is fixedly connected to the top of the deflecting rod. A first spring is fixedly connected to the bottom of the deflecting rod. The other end of the first spring is fixedly connected to the top of the fixed plate. A movable plate is provided inside the housing. A locking groove adapted to the locking block is opened at the bottom of the movable plate.

[0008] Preferably, a sliding plate is fixedly connected to the inner side wall of the housing, the movable plate slides on the sliding plate, and a buffer block is fixedly connected to the side wall of the sliding plate.

[0009] Preferably, a connecting column is fixedly connected to the inner side wall of the housing, a second spring is fixedly connected to one end of the connecting column, and a connecting block is fixedly connected to the other end of the second spring.

[0010] Preferably, the top of the connecting block is fixedly connected to the bottom of the movable plate, and a limit frame is fixedly connected to the top of the movable plate.

[0011] Preferably, the top of the movable plate is fixedly connected to a housing, the inside of the housing is slidably connected to a linkage plate, and the outside of the linkage plate is fixedly connected to a clamping rod, which passes through the housing, the linkage plate, and the limiting frame.

[0012] Preferably, a third spring is sleeved on the outer side of the clamping rod, one end of the third spring is fixedly connected to the inner side wall of the housing, and the other end of the third spring is fixedly connected to the side wall of the linkage plate.

[0013] Preferably, one end of the clamping rod is fixedly connected to a positioning frame, the positioning frame is inside the limiting frame, a dust cover is fixedly connected to the side wall of the housing, an exhaust fan is provided on the side wall of the housing, and a PLC temperature sensor is provided on the side wall of the housing.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] The locking assembly allows for the quick ejection and insertion of the movable plate when cable inspection or maintenance is required. Through the coordinated design of the deflection rod, first spring, rotating shaft, fixing bracket, and first spring, when maintenance is needed on a specific layer of cable, simply releasing the locking assembly allows the corresponding movable plate to pop out, creating an independent operating space.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: Reference Figure 1-5The PLC control cabinet shown includes a housing 1, which serves as the main body of the control cabinet, housing and protecting the internal electrical components and wiring, providing a protective space to prevent external dust, moisture, and debris from affecting the normal operation of the internal components. A fixing plate 8 is fixedly connected inside the housing 1, supporting and fixing the locking assembly, providing a stable mounting base for the locking assembly, ensuring its stability during operation, and preventing shaking or displacement. A locking assembly is located on the top of the fixing plate 8, used to lock and release the moving plate 6, meeting the need for fixing the moving plate 6 during daily use, and allowing for quick unlocking and ejection of the moving plate 6 during maintenance. The locking assembly includes a fixing bracket 20 fixedly connected to the top of the fixing plate 8, supporting and fixing the rotating shaft 4, ensuring stable rotation of the rotating shaft 4, and providing a reliable support structure for the rotation of the deflection rod 21. A rotating shaft 4 is rotatably connected to the side wall of the fixed frame 20. The rotating shaft 4 is the axis of rotation of the deflection rod 21. The rotation of the rotating shaft 4 drives the deflection rod 21 to change its angle, thereby realizing the engagement and disengagement of the locking block 22 and the locking slot 15. The deflection rod 21 is fixedly connected to the side wall of the rotating shaft 4. The deflection rod 21 drives the locking block 22 to move through its own rotation. Under normal conditions, the locking block 22 is engaged in the locking slot 15 to fix the moving plate 6. During maintenance, the deflection rod 21 is pushed upward to move the locking block 22 out of the locking slot 15, releasing the restriction on the moving plate 6. The top of the deflection rod 21 is fixedly connected to the locking block 22, which is adapted to the locking slot 15 at the bottom of the moving plate 6. By locking the locking block 22 into the locking slot 15, the moving plate 6 is firmly fixed in the housing 1, preventing the moving plate 6 from shifting during use and ensuring the stability of the wiring positioning mechanism and the internal wiring. A first spring 23 is fixedly connected to the bottom of the deflection rod 21. The other end of the first spring 23 is fixedly connected to the top of the fixed plate 8. The first spring 23 provides the deflection rod 21 with a reset force. When the deflection rod 21 is pushed upward to disengage the locking block 22 from the locking slot 15, and the moving plate 6 needs to be re-fixed after maintenance, the deflection rod 21 is released. The force of the first spring 23 will push the deflection rod 21 to reset, so that the locking block 22 is re-locked into the locking slot 15, thereby fixing the moving plate 6 again. The housing 1 has a movable plate 6 inside, which is used to support the cable positioning mechanism and the cable. It is connected to the fixed plate 8 through a locking assembly. When it is necessary to inspect or maintain a certain layer of cable, it can pop out after the locking assembly is released, providing an independent operating space for inspection and maintenance. This makes it convenient for staff to inspect, repair, and replace the cable. The bottom of the movable plate 6 has a slot 15 that matches the locking block 22. The slot 15 and the locking block 22 cooperate to form a locking structure, realizing the connection and fixation between the movable plate 6 and the fixed plate 8. This ensures that the movable plate 6 remains stable during normal operation and can be quickly unlocked when it needs to pop out.

[0026] Example 2: Reference Figure 1-5Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a sliding plate 7 is fixedly connected to the inner side wall of the housing 1. The sliding plate 7 provides a sliding track for the moving plate 6, allowing the moving plate 6 to smoothly pop outward and retract inward along its direction, ensuring the stability and guidance of the moving plate 6's movement, and preventing deviation or jamming during movement. The moving plate 6 slides on the sliding plate 7, and the pop-out and retraction actions of the moving plate 6 are achieved by sliding on the sliding plate 7, facilitating the maintenance and repair of the wiring on the moving plate 6 by the staff. A buffer block 16 is fixedly connected to the side wall of the sliding plate 7. The buffer block 16 is used to buffer the moving plate 6 during pop-out or retraction, preventing the moving plate 6 from violently colliding with the end of the sliding plate 7 due to inertia, reducing the impact force generated by the collision, protecting the moving plate 6, the sliding plate 7, and the internal wiring and components from damage, and extending the service life of the equipment. A connecting post 17 is fixedly connected to the inner side wall of the housing 1. The connecting post 17 is used to fix one end of the second spring 18, providing a stable mounting support point for the second spring 18, ensuring that the second spring 18 will not be displaced during operation, and ensuring the effectiveness of its elastic force. A second spring 18 is fixedly connected to one end of the connecting post 17. When the engaging assembly is disengaged, the second spring 18 recovers its deformation from a compressed state, generating elastic force. This force pushes the moving plate 6 outward along the sliding plate 7 via the connecting block 19, providing power for the pop-out of the moving plate 6. After maintenance, when the moving plate 6 is pushed back to its original position, the second spring 18 is compressed, storing elastic potential energy for future use. The other end of the second spring 18 is fixedly connected to the connecting block 19, which connects the second spring 18 and the moving plate 6, transmitting the elastic force of the second spring 18 to the moving plate 6, enabling the moving plate 6 to pop out under the action of the spring force. The top of the connecting block 19 is fixedly connected to the bottom of the moving plate 6, ensuring a stable connection between the moving plate 6 and the connecting block 19, and ensuring that the elastic force of the second spring 18 can effectively act on the moving plate 6. A limiting frame 10 is fixedly connected to the top of the movable plate 6. The limiting frame 10 is used to initially limit the cable, guide the cable to be laid along a predetermined path, keep the cable neat and orderly on the movable plate 6, and at the same time provide installation space and range of motion restriction for the positioning frame 14, ensuring that the positioning frame 14 can accurately position the cable. A housing 9 is fixedly connected to the top of the movable plate 6. The housing 9 provides installation space and protection for components such as the linkage plate 11, clamping rod 12, and third spring 13, preventing these components from being affected by external collisions, dust, etc., and ensuring the normal realization of the cable positioning function. The linkage plate 11 is slidably connected inside the housing 9. The linkage plate 11 slides inside the housing 9 under the action of the clamping rod 12. The sliding of the linkage plate 11 realizes the opening and closing action of the positioning frame 14, thereby clamping or releasing the cable.A clamping rod 12 is fixedly connected to the outer side of the linkage plate 11. The clamping rod 12 is for manual operation by the operator. By pulling the clamping rod 12, the linkage plate 11 is slidable, thereby controlling the positioning frame 14. This allows the operator to place and fix the cable in the appropriate position. The clamping rod 12 passes through the outer shell 9, the linkage plate 11, and the limiting frame 10, ensuring that the clamping rod 12 can stably transmit the operating force, enabling the linkage plate 11 and the positioning frame 14 to respond accurately to the operation. A third spring 13 is sleeved on the outer side of the clamping rod 12. The third spring 13 is compressed when the clamping rod 12 is pulled, storing elastic potential energy. When the clamping rod 12 is released, the third spring 13 releases the elastic potential energy, pushing the linkage plate 11 and the positioning frame 14 to reset, causing the positioning frame 14 to clamp the cable, thereby fixing the cable in place. One end of the third spring 13 is fixedly connected to the inner side wall of the outer shell 9, and the other end is fixedly connected to the side wall of the linkage plate 11, providing a mounting point for the third spring 13 and ensuring that it can stably exert its elastic force during operation. One end of the clamping rod 12 is fixedly connected to a positioning frame 14, which is inside the limiting frame 10. The positioning frame 14, in cooperation with the limiting frame 10, precisely positions and clamps the cable, ensuring that the cable will not shift or loosen during use, thus guaranteeing a neat cable layout and stable electrical connections. A dust cover 2 is fixedly connected to the side wall of the housing 1. The dust cover 2 prevents external dust and debris from entering the housing 1 through the ventilation fan 5 or other openings, protecting the electrical components and cables inside the housing 1 from dust damage, reducing malfunctions caused by dust accumulation, and extending the equipment's service life. A ventilation fan 5 is installed on the side wall of the housing 1. When the PLC temperature sensor 3 detects that the internal temperature of the housing 1 is too high, the ventilation fan 5 automatically starts to provide forced ventilation, accelerating airflow inside the housing 1, dissipating heat, and lowering the internal temperature of the housing 1. This ensures that the electrical components operate in a suitable temperature environment, preventing performance degradation or damage due to excessive temperature. A PLC temperature sensor 3 is installed on the side wall of the housing 1. The PLC temperature sensor 3 monitors the temperature inside the housing 1 in real time. When the temperature exceeds the set threshold, it sends a signal to the control system to trigger the ventilation fan 5 to start, thereby realizing the automatic adjustment and monitoring of the temperature inside the housing 1.

[0027] The working principle of this utility model is as follows: When using this control cabinet, first pass the cable through the limit frame 10, pull the clamping rod 12 to make the linkage plate 11 slide and compress the third spring 13 inside the outer casing 9, and the positioning frames 14 on both sides open. Place the cable between them, release the clamping rod 12, and use the elastic force of the third spring 13 to position the positioning frame 14 for the cable. When it is necessary to inspect and maintain a specific cable on a certain layer, push the deflection rod 21 upward to disengage the locking block 22 from the locking slot 15. The second spring 18 returns to its compressed state, and the moving plate 6 pops out along the sliding plate 7 through the connecting block 19. When the PLC temperature sensor 3 detects that the temperature inside the casing 1 is too high, the ventilation fan 5 is automatically started to ventilate and cool the inside of the casing 1.
