Description

Technical Field

[0001] This utility model relates to the field of PLC programming control cabinets, specifically an automatic PLC programming control cabinet for industrial control platforms. Background Technology

[0002] An industrial control platform, short for industrial automation control platform, is a collection of hardware and software systems used for industrial automation control, enabling the monitoring and control of production processes or equipment. It plays a core role in industrial production, ensuring efficient, stable, and safe operation, and achieving automated and intelligent control goals. An indispensable component of this platform is the PLC programming control cabinet.

[0003] Patent CN218125150U discloses a PLC programming control cabinet. Specifically, this patent discloses that the present invention is equipped with a fire extinguishing component. When the wiring and electrical components inside the cabinet are damaged or burned, the heat generated melts the first and second heat-melting barrier plates of the fire extinguishing tube. This causes the carbon dioxide stored inside the fire extinguishing tube to be sprayed out from the side of the fire extinguishing tube and the ventilation groove, isolating the oxygen at the fire site, thereby extinguishing the fire quickly and preventing the fire from spreading, thus providing a certain degree of protection.

[0004] To address the aforementioned issues, while existing patents offer solutions that provide protection through the use of components such as fire extinguishers, in practice, the numerous devices on the industrial control platform can generate significant strong magnetic interference, which can affect the internal components of the PLC programming control cabinet and thus disrupt the entire operating system. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic PLC programming control cabinet for industrial control platforms, so as to solve the problems mentioned in the background art and overcome its technical defects.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0026] Please see Figures 1 to 3An automatic PLC programming control cabinet for an industrial control platform includes a cabinet body 1. An equipment cavity 2 is located at the top of the cabinet body 1, and a cable cavity 3 is located at the bottom of the cabinet body 1. A grounding plate 4 is fixedly installed at the bottom of the cabinet body 1. A main body of control electrical equipment 5 is fixedly installed on one side of the equipment cavity 2. A through hole 6 is located at the bottom of the equipment cavity 2, and a positioning mechanism 7 is provided on one side of the through hole 6. The positioning mechanism 7 includes a sleeve 701, which extends out of the through hole 6, and the top of the outer wall of the sleeve 701 is fitted with... A copper plate 702 is provided. A rotating collar 703 is rotatably connected to the bottom of the outer wall of the sleeve 701. A limit plate 704 is fixedly installed on one side of the bottom of the rotating collar 703. A rotating rod 705 is rotatably connected to one side of the inner side of the cable cavity 3. A threaded rod 706 is fixedly installed at one end of the rotating rod 705. An abutment plate 707 is slidably connected to the outer wall of the threaded rod 706. A pressing head 708 is fixedly installed on the outer wall of the abutment plate 707. The sleeve 701 is threadedly connected to the copper plate 702 and to the through hole 6.

[0027] By adopting the above technical solution, the equipment cavity 2 and the cable cavity 3 can form a closed effect, avoiding gaps and thus forming a Faraday cage with the grounding plate 4, thereby achieving the effect of anti-electromagnetic interference. In conjunction with the sleeve 701 and copper plate 702 inside the through hole 6, it can limit and classify cables for easy later maintenance, while further achieving sealing and anti-interference effects. The manual adjustment of the rotating rod 705 drives the threaded rod 706 to rotate, so that the contact plate 707 drives the pressing head 708 to pass through the limiting plate 704 to clamp and fix the cable, achieving the effect of preventing loosening. The rotating collar 703 fixed by the limiting plate 704 is engaged with the sleeve 701, which can always adjust the position of the corresponding pressing head 708.

[0028] Specifically, such as Figure 2 and Figure 4 As shown, a through hole 8 is provided at the bottom of the inner cavity of the cable cavity 3. An abutment mechanism 9 is provided above the through hole 8. The abutment mechanism 9 includes a connecting plate 901. The connecting plate 901 is fixedly installed at the bottom of the abutment plate 707. A spring 902 is embedded in one side of the outer wall of the connecting plate 901. A connecting frame 903 is fixedly installed at one end of the spring 902. An abutment roller 904 is rotatably connected between the two axes of the connecting frame 903. A connecting plate 905 is fixedly installed at one end of the two axes of the connecting frame 903. The structure of the connecting frame 903 is a U-shaped structure. The connecting frame 903 forms an elastic structure with the connecting plate 901 through the spring 902.

[0029] By adopting the above technical solution, during the displacement of the contact plate 707, the connecting plate 901 moves accordingly, and the connecting frame 903 is pushed elastically by the spring 902, causing the contact roller 904 to rotate and contact the cable. The elastic push of the spring 902 allows for a portion of the cable length to be reserved. When pulled, the spring 902 elastically contracts, preventing loosening and breakage due to direct pulling. It also works with the connecting plate 905 to prevent the cable from leaving the range of the connecting frame 903. The through hole 8 is equipped with a sleeve 701 and a copper plate 702, allowing the cable to pass through the cabinet 1 while maintaining airtightness.

[0030] Working principle: First, cabinet 1 is equipped with equipment cavity 2 and cable cavity 3. Equipment cavity 2 is used to house the main body of control electrical equipment 5, which consists of PLC programming control electrical components and other compatible electrical components. This is conventional technology and will not be elaborated further. Equipment cavity 2 is sealed and grounded through grounding plate 4 to form a Faraday cage, avoiding shielding against external electromagnetic interference. The through hole 6 in cable cavity 3 facilitates the cable lead-out of the main body of control electrical equipment 5. A copper sleeve 701 is threadedly connected to the through hole 6, and a copper plate 702 is assembled with the sleeve 701, thus providing some electromagnetic interference protection at the through hole 6. After the cable is connected, the rotating rod 705, which is connected to the cable cavity 3 via a bearing, is manually rotated, causing the threaded rod 706 to rotate, facilitating the threading of the threaded rod 706. The contact plate 707 of the threaded connection is positioned such that its top end fits against the partition of cabinet 1, and corresponding reserved blocks and slots are provided to prevent the contact plate 707 from rotating with the threaded rod 706. This facilitates the pressing head 708 to abut against the limiting plate 704 at the bottom of the rotating collar 703 to clamp and fix the cable. With the displacement of the contact plate 707, the connecting plate 901 can follow the displacement, thereby allowing the connecting frame 903 to be pushed elastically by the spring 902, causing the contact roller 904 to rotate and abut against the cable. Under the limitation of the connecting plate 905, slippage is prevented. When subjected to tensile force, the elastic contraction of the spring 902 can reserve some cable movement space to prevent direct pulling from causing the connection to break. The cable passes through the through hole 8, and the sleeve 701 and copper plate 702 are only provided to further prevent electromagnetic interference.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
