[0001] The present invention relates to the technical field of industrial control computers, and specifically relates to a data wiring port structure for an industrial control computer. Background Art

[0002] An industrial control computer, that is, an industrial control computer, has the characteristics of high stability, anti-interference, high and low temperature resistance, and long-term continuous operation, and is widely used in various industrial control scenarios such as intelligent manufacturing and automated production lines. It is mainly used for industrial data collection, equipment operation regulation, system signal transmission and linkage control, and is the core operation and control terminal of an industrial automatic control system. As a core connection component for data interaction and signal transmission between the industrial control computer and external peripherals such as sensors and actuators, the connection stability and protection performance of the data wiring port directly determine the data transmission accuracy of the industrial control computer, the safety of equipment operation and the working reliability of the overall control system.

[0003] The prior art (Chinese Patent with Publication No. CN117742458A and Publication Date of March 22, 2024) discloses a data interface protection device for an industrial control computer. The data interface protection device for an industrial control computer comprises: an industrial control computer; a driving assembly, which is arranged on the back surface of the industrial control computer, and the traveling direction of the driving assembly is consistent with the opening direction of the data interface of the industrial control computer; a protection assembly, which is arranged on the driving assembly and located at the data interface of the industrial control computer. The protection assembly can protect the data interface of the industrial control computer, and the unused data interface can be sealed by the protection assembly, which effectively prevents the data interface of the industrial control computer from accumulating dust, and improves the stability of data line connection, so that loosening and disconnection are not easy to occur, and the use stability is guaranteed. Moreover, during operation, only the action of repeatedly rotating the rotating screw is required, which is more convenient to use; the prior art (Chinese Patent with Publication No. CN220121222U and Publication Date of December 1, 2023) discloses a data interface structure for an industrial control computer, which comprises an industrial control computer main body, a through groove, connection ports and dust-proof plates. A through groove is arranged at the bottom end of one side of the industrial control computer main body, connection ports are uniformly arranged in the through groove at equal intervals, an outer protection frame is connected and arranged on one side of the exterior of the connection port, the connection port and the outer protection frame are fixedly connected, valve cores are uniformly arranged on one side of the exterior of the industrial control computer main body at equal intervals. By fixedly connecting the outer protection frame to the exterior of the connection port, the insulation protection effect on the data line and the interface can be achieved. At the same time, by opening the valve cores, an external inflator can inflate the interior of the safety airbag, and the safety airbag can be inflated and expanded to closely attach to the surface of the external data line, so as to ensure the connection stability between the connection port and the external data line, thereby enabling the industrial control computer to perform data transmission operations stably.

[0004] While existing industrial control computer data connection port structures can protect the ports when they are not connected, they cannot continue to seal and protect the port connections when they are connected, which has certain limitations. Summary of the Invention

[0005] The purpose of this invention is to provide a data connection port structure for industrial control computers, in order to solve the problem mentioned in the background art that although the current data connection port structures for industrial control computers on the market can protect the port when it is not connected, they cannot continue to seal and protect the port connection when it is connected.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a data connection port structure for an industrial control computer, comprising a mounting bracket fixedly installed on the industrial control computer, a terminal block fixedly installed on the mounting bracket, a connector plug inserted into the outer side of the terminal block, a rotating seat elastically mounted at the end of the terminal block, a transmission component provided between the connector plug and the rotating seat, and the rotating seat being driven to rotate by the transmission component during the connection of the terminal block and the connector plug, a sliding seat elastically slidably installed on the inner side of the terminal block, and a sealing cylinder being sealed and fixedly connected between the rotating seat and the sliding seat, and a gas supply component provided on the terminal block and the sealing cylinder, wherein the gas supply component discharges the gas between the terminal block and the connector plug when they are connected.

[0007] Preferably, the inner diameter of the housing of the terminal block is smaller than the inner diameter of the rotating base, and the terminal block and the rotating base are fitted with a clearance.

[0008] Preferably, the transmission assembly includes a first guide groove formed on the outer wall of the connector plug, and the first guide groove has a spiral structure. A ball is embedded in the inner wall of the rotating seat. During the insertion and connection of the connector terminal and connector plug, the ball slides along the first guide groove, and the ball drives the rotating seat to rotate synchronously and elastically during the rolling of the ball along the first guide groove.

[0009] Preferably, the outer wall of the connector is further provided with a second guide groove and a third guide groove, and the two ends of the second guide groove are respectively connected to the first guide groove and the third guide groove. The second guide groove is straight, and the ball slides along the second guide groove during the connector insertion process.

[0010] Preferably, the third guide groove is arc-shaped, and when the ball slides into the third guide groove, the rotating seat elastically rotates and resets, and the ball and the third guide groove position the connector in the insertion direction.

[0011] Preferably, the sealing cylinder is cylindrical, and the rotating seat cooperates with the sliding seat to twist the sealing cylinder in the initial state. After the sealing cylinder is twisted, the inner wall of the middle position is sealed and fitted, and the twisted sealing cylinder seals and protects the terminal.

[0012] Preferably, a return spring is fixedly connected between the sliding seat and the terminal, and the sliding seat is pulled closer to the rotating seat during the torsion of the sealing cylinder, and the sliding seat slides back to its original position under the elastic force of the return spring when the rotating seat rotates elastically.

[0013] Preferably, when the terminal and plug are connected, the ball slides along the third guide groove, and the sealing cylinder is twisted again during the rotation and reset of the rotating seat, and the sealing cylinder is sealed and adhered to the outside of the plug during the twisting process.

[0014] Preferably, the air supply assembly includes a filter inlet pipe that passes through and is installed on the terminal block and an air blowing pipe that passes through the sealing cylinder. Both the filter inlet pipe and the air blowing pipe are equipped with a one-way valve structure. When the sealing cylinder is twisted, the cavity between it and the terminal block draws in filtered air through the filter inlet pipe. When the sealing cylinder is stretched and restored, the air drawn in between it and the terminal block is blown through the air blowing pipe between the terminal block and the connector. An exhaust pipe is provided on the rotating seat, and a one-way valve is provided on the exhaust pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the industrial control computer data wiring port structure can conveniently realize the wiring lock of the port, and realize the sealing protection in the wiring and non-wiring states through a single sealing mechanism, effectively ensuring the wiring stability, as detailed below; 1. It is equipped with a terminal, a plug, and a rotating base. By inserting the terminal and plug, the ball bearings on the rotating base gradually roll along the first guide groove, the second guide groove, and the third guide groove, thereby driving the rotating base to rotate elastically and reset. The ball bearings cooperate with the third guide groove to lock the plug in, preventing the terminal from coming loose during use and affecting normal operation, thus preventing a decrease in production efficiency.

[0016] 2. Equipped with a rotating seat, a sliding seat, and a sealing cylinder, the rotating seat rotates elastically via a torsion spring and the terminal, which in turn, in conjunction with the sliding seat, twists the sealing cylinder. This ensures a tight seal between the inner walls of the sealing cylinder and the terminal, automatically sealing the terminal and preventing dust accumulation and accelerated corrosion due to prolonged exposure. Furthermore, as the connector is gradually inserted, the rotating seat rotates elastically under the guidance of the first guide groove, causing the sealing cylinder to gradually stretch and recover, allowing the connector to pass through the inside of the sealing cylinder. After the connector and connector are fully inserted, the ball moves into the third guide groove, causing the rotating seat to rotate elastically again. This, in turn, works with the sliding seat to twist the sealing cylinder again, allowing the sealing cylinder to seal against the outside of the connector, thus achieving the purpose of protecting the connector.

[0017] 3. Equipped with a filter air inlet pipe, an air blowing pipe, and an exhaust pipe, when the wiring terminals and plugs are connected, the sealing cylinder assembly returns to its original position and gradually approaches the inner wall of the wiring terminal. This allows the air drawn in through the filter air inlet pipe to be blown between the wiring terminals and plugs through the air blowing pipe, creating airflow between them. This, in turn, causes the air between them to be discharged through the exhaust pipe, preventing dust initially mixed in with the air between them from affecting the electrical connection and further ensuring wiring stability.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: While existing industrial control computer data connection port structures can protect the ports when disconnected, they cannot continue to seal and protect the port connections when connected. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-4 and Figures 6-8As shown, a data connection port structure for an industrial control computer includes a mounting bracket 1 fixedly installed on the industrial control computer. A terminal 2 is fixedly installed on the mounting bracket 1, and a connector 3 is inserted into the outer side of the terminal 2. A rotating seat 4 is elastically rotatably installed at the end of the terminal 2. A transmission component is provided between the connector 3 and the rotating seat 4. During the connection process between the terminal 2 and the connector 3, the rotating seat 4 is driven to rotate through the transmission component. A sliding seat 5 is elastically slidably installed on the inner side of the terminal 2, and a sealing cylinder 6 is sealed and fixedly connected between the rotating seat 4 and the sliding seat 5. The sealing cylinder 6 may be made of elastic rubber.

[0022] The inner diameter of the housing of the terminal 2 is smaller than the inner diameter of the rotating base 4, and the connector 3 and the rotating base 4 are clearance-fitted. The transmission assembly includes a first guide groove 301 formed on the outer wall of the connector 3, and the first guide groove 301 has a spiral structure. A ball bearing 401 is embedded in the inner wall of the rotating base 4. During the insertion of the terminal 2 and the connector 3, the ball bearing 401 slides along the first guide groove 301, and during the rolling of the ball bearing 401 along the first guide groove 301, it drives the rotating base 4 to rotate synchronously and elastically. The outer wall of 3 is also provided with a second guide groove 302 and a third guide groove 303. The two ends of the second guide groove 302 are respectively connected to the first guide groove 301 and the third guide groove 303. The second guide groove 302 is straight. During the insertion of the connector 3, the ball 401 slides along the second guide groove 302. The third guide groove 303 is arc-shaped. When the ball 401 slides into the third guide groove 303, the rotating seat 4 rotates and resets elastically. The ball 401 and the third guide groove 303 position the connector 3 in the insertion direction.

[0023] By connecting the terminal 2 and the connector 3, the ball bearing 401 on the rotating base 4 gradually rolls along the first guide groove 301, the second guide groove 302, and the third guide groove 303. Since the first guide groove 301 is spiral, the ball bearing 401 drives the rotating base 4 to rotate. The third guide groove 303 is arc-shaped. When the ball bearing 401 moves into the third guide groove 303, the torsion spring between the rotating base 4 and the terminal 2, due to their elastic rotational connection, drives the rotating base 4 to rotate. At this time, the ball bearing 401 slides along the third guide groove 303, allowing the ball bearing 401 to engage and lock the connector 3 with the third guide groove 303. This prevents the connector from becoming loose during use and affecting normal operation, thus preventing a decrease in production efficiency. Subsequently, simply rotating the rotating base 4 causes the ball bearing 401 to move to the second guide groove 302. At this time, the ball bearing 401 can slide in opposite directions along the second guide groove 302 and the first guide groove 301, allowing the connector 3 to be pulled out.

[0024] The sealing cylinder 6 is cylindrical, and in the initial state, the rotating seat 4 cooperates with the sliding seat 5 to twist the sealing cylinder 6. After twisting, the inner wall of the middle position of the sealing cylinder 6 is sealed and adhered. At the same time, the twisted sealing cylinder 6 seals and protects the terminal 2. A return spring 501 is fixedly connected between the sliding seat 5 and the terminal 2. During the twisting process of the sealing cylinder 6, the sliding seat 5 is pulled to slide close to the rotating seat 4. When the rotating seat 4 rotates elastically, the sliding seat 5 slides and resets under the elastic force of the return spring 501. When the terminal 2 and the connector 3 are inserted, the ball 401 slides along the third guide groove 303. During the rotation reset process of the rotating seat 4, the sealing cylinder 6 is twisted again, and during the twisting process again, the sealing cylinder 6 is sealed and adhered to the outside of the connector 3.

[0025] In the non-connected state, the rotating seat 4 rotates elastically through the torsion spring and the terminal 2, thereby cooperating with the sliding seat 5 to twist the sealing cylinder 6, so that the inner wall of the middle position of the sealing cylinder 6 is sealed and fitted, realizing automatic sealing of the terminal 2 and preventing the terminal 2 from being exposed for a long time and accumulating dust and accelerating corrosion. As the terminal 3 is gradually inserted, the rotating seat 4 rotates elastically under the guidance of the first guide groove 301, and the sliding seat 5 moves away from the rotating seat 4 under the elastic force of the return spring 501, so that the sealing cylinder 6 is gradually stretched and returned to its original position. The original shape is changed to a cylindrical shape, allowing the connector 3 to pass through the inside of the sealing cylinder 6. After the connector 2 and connector 3 are connected, the ball 401 moves into the third guide groove 303, causing the rotating seat 4 to rotate elastically again. This, in turn, cooperates with the sliding seat 5 to twist the sealing cylinder 6 again, so that the twisted sealing cylinder 6 can seal and fit against the outside of the connector 3, achieving the purpose of encircling and sealing the connector 3, thus protecting the connection point. In this way, the same sealing mechanism can achieve sealing protection in both connected and unconnected states.

[0026] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing industrial control computer data connection port structures are inconvenient for pre-expelling dust-laden gas from the interface during connection, thus affecting wiring stability. To further solve this technical problem, this example discloses the following technical content: Figures 4-6 As shown, gas delivery components are provided on the terminal 2 and the sealing cylinder 6, and when the terminal 2 and the plug 3 are connected, the gas delivery components discharge the gas between them.

[0027] The air supply assembly includes a filter inlet pipe 7 that passes through the terminal 2 and an air blowing pipe 8 that passes through the sealing cylinder 6. Both the filter inlet pipe 7 and the air blowing pipe 8 are equipped with a one-way valve structure. When the sealing cylinder 6 is twisted, the cavity between it and the terminal 2 draws in filtered air through the filter inlet pipe 7. When the sealing cylinder 6 is stretched and restored, the air drawn in between it and the terminal 2 is blown through the air blowing pipe 8 between the terminal 2 and the connector 3. An exhaust pipe 9 is provided on the rotating seat 4, and a one-way valve is provided on the exhaust pipe 9.

[0028] When terminal 2 and connector 3 are plugged in, the sealing cylinder 6 assembly returns to its original position and gradually approaches the inner wall of terminal 2. This allows air drawn in through the filter intake pipe 7 to be blown between terminal 2 and connector 3 through the air blowing pipe 8, creating airflow between them. This, in turn, causes the air between them to be discharged through the exhaust pipe 9, preventing dust mixed in with the initial air between them from affecting the electrical connection and further ensuring wiring stability. When connector 3 is pulled out, the sealing cylinder 6 twists, increasing the cavity between it and terminal 2, and then the filter intake pipe 7 draws in the remaining filtered air.
