[0002] As the core equipment for industrial automation control, industrial control computers are typically deployed in harsh industrial environments such as dust, humidity, and vibration. The reliability and protection capabilities of their data interfaces directly affect the stable operation of the production system. Data interfaces not only face the risk of poor contact due to dust and moisture corrosion, but also frequently experience loosening or detachment of data cable connectors due to cable dragging, equipment movement, or accidental collisions, which can even cause physical damage to the interface or communication interruption in severe cases.

[0003] Patent No. CN217062608U discloses a data interface protection device for industrial control computers. This device achieves dust and moisture protection for the data interface by sliding a protective cover on the top of the industrial control computer and hinged a protective shell with a sealing strip at one end. The device uses an interlocking structure of adjusting blocks, locking blocks, and fixing blocks to keep the protective cover stable in the closed state. However, this device lacks any anti-pull or anti-loosening structural design. In industrial settings, personnel movement, equipment vibration, or accidental cable contact can easily cause the connector to loosen, affecting the continuity and reliability of data transmission. Therefore, there is an urgent need for a data interface protection device for industrial control computers to solve these problems. Summary of the Invention

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-5 This invention provides a technical solution: a data interface protection device for an industrial control computer, comprising an industrial control computer body 1 and an adjustment component. A rectangular shell 2 is fixed to the right side of the industrial control computer body 1. Multiple T-shaped grooves 5 are provided above the rectangular shell 2, and the bottom surfaces of each T-shaped groove 5 are provided with rectangular grooves 7 communicating with the interior of the rectangular shell 2. A cover plate 3 is installed on the right side of the rectangular shell 2. An operating groove 11 is provided through the middle of the right side of the cover plate 3, and a receiving groove 8 is provided above the operating groove 11. The adjustment component includes a mounting base 12, a bidirectional lead screw 15, and a clamping plate 18. A rotating shaft 13 is rotatably mounted through the middle of the mounting base 12. A worm gear 14 is fixed to the left end of the 13. A worm wheel ring 21 is fixedly sleeved on the outer side of the middle of the double-acting screw 15. An anti-slip pad 19 is fixed to the front side of the clamping plate 18. A T-shaped block 16 is symmetrically threaded to the outer side of the double-acting screw 15. A right-angled round rod 17 is fixed to the lower end of the T-shaped block 16. There are two clamping plates 18. The two clamping plates 18 are fixedly connected to the two right-angled round rods 17 respectively. This design solves the problem that the original device lacks any anti-pull and anti-loosening structural design. In the industrial field, personnel walking, equipment vibration or accidental contact with cables can easily cause the joints to loosen, affecting the continuity and reliability of data transmission.

[0016] As a first embodiment of the present invention: Multiple mounting slots 6 are provided above the cover plate 3. An iron door panel 4 is slidably installed inside the receiving slot 8. The sliding fit between the receiving slot 8 and the iron door panel 4 forms an openable and closable cover structure for the operating slot 11. It can be closed when not in use, providing a certain degree of protection for the data cable interface 20 area. A first magnetic sheet 9 is installed above the receiving slot 8, and a second magnetic sheet 10 is installed below the operating slot 11. Utilizing the magnetic attraction of the first magnetic sheet 9 and the second magnetic sheet 10 to the iron door panel 4, a bistable positioning of the door panel in open and closed states is achieved. No additional snap-fit ​​structure is required, resulting in smooth operation and reliable positioning, improving ease of use. Multiple data cable interfaces 20 are provided on the right side of the industrial control computer body 1.

[0017] Multiple adjustment components are provided. The mounting base 12 is fixed in the mounting groove 6. The bidirectional lead screw 15 is rotatably connected to the inner wall of the T-shaped groove 5. The T-shaped block 16 is slidably connected to the inner wall of the T-shaped groove 5. The lower end of the T-shaped block 16 passes through the rectangular groove 7. Multiple sets of adjustment components are independently set to realize parallel and independent clamping control of multiple data cable interfaces 20 without interference. The mounting base 12 is fixed in the mounting groove 6 to ensure the structural stability of the worm gear 14 during transmission. The bidirectional lead screw 15 is rotatably connected to the inner wall of the T-shaped groove 5, and the T-shaped block 16 is slidably engaged with the T-shaped groove 5 to form a precise rotation-linear motion conversion guide. The lower end of the T-shaped block 16 extends through the rectangular groove 7 into the interior of the rectangular shell 2, so that the clamping plate 18 can be positioned directly opposite the data cable interface 20. The worm 14 is meshed with the worm wheel ring 21, and the other end of the worm 14 is rotatably connected to the inner wall of the T-slot 5. The meshing of the worm 14 and the worm wheel ring 21 forms a worm gear transmission pair, which utilizes its unidirectional transmission characteristics to achieve mechanical self-locking in the clamping state. When the cable is pulled by external force, it cannot drive the screw to loosen in the reverse direction. The other end of the worm 14 is rotatably connected to the inner wall of the T-slot 5, which improves the smoothness of transmission.

[0018] As a second embodiment of the present invention: When using this device, the operator first slides the iron door panel 4 upward from the receiving groove 8, and the first magnetic sheet 9 attracts the iron door panel 4 to keep it in the open state. Then, the data cable connector is inserted into the corresponding data cable interface 20 on the right side of the industrial control computer body 1. Next, the rotating shaft 13 is turned, and the rotating shaft 13 drives the worm gear 14 to rotate. The worm gear 14 drives the worm wheel ring 21 that meshes with it to rotate. The worm wheel ring 21 drives the bidirectional lead screw 15 to rotate in the inner wall of the T-shaped groove 5. When the bidirectional lead screw 15 rotates, the two T-shaped blocks 16 with symmetrical threaded connections on its outer side slide synchronously towards each other in opposite directions under the guidance of the T-shaped groove 5. The lower end of the T-shaped block 16 passes through the rectangular... The groove 7 drives the right-angled round rod 17 and the clamping plate 18 to move closer to the center line until the anti-slip pad 19 on the front side of the clamping plate 18 adheres to and presses against the root of the data cable connector. After clamping, the meshing self-locking characteristic of the worm gear 14 and the worm wheel ring 21 prevents the bidirectional lead screw 15 from rotating in the opposite direction, achieving mechanical self-locking and preventing the cable from being accidentally pulled loose. When it is necessary to remove the cable, the rotating shaft 13 is turned in the opposite direction, the worm gear 14 drives the worm wheel ring 21 to rotate in the opposite direction, the bidirectional lead screw 15 drives the T-shaped blocks 16 on both sides to slide in the opposite direction, and the clamping plates 18 move away from each other to release the cable. After use, the iron door plate 4 is slid down into the operating groove 11, and the second magnetic sheet 10 attracts the iron door plate 4 to keep it in a closed state.
