A gateway structure for an IoT tunnel area controller device

Abstract

This invention discloses a gateway structure for an IoT tunnel area controller device, relating to the field of gateway technology. It includes a gateway housing and a terminal assembly. The gateway housing has a wiring cavity inside, and the terminal assembly includes terminal pieces disposed within the wiring cavity. A transmission plate is disposed below the electromagnetic plate. This IoT tunnel area controller gateway structure, when the device wire ends are inserted into the wiring holes and clamped, utilizes the repulsive force generated by the energized electromagnetic plate for initial clamping. Then, a bolt is used to fix the cover plate, causing the bottom of the elastic piston rod to adhere to the surface of the electromagnetic plate and push it downwards. This allows the electromagnetic plate, in a de-energized state, to push against the transmission plate, further clamping each wire end on top of the initial clamping. This process eliminates the need for frequent tightening of screws inside the vertical holes, greatly reducing the complexity of connecting multiple wire ends to terminals and significantly reducing the repetitive work of manually tightening the screws used to clamp the wire ends.

Description

Technical Field

[0001] This invention relates to the field of gateway technology, specifically to a gateway structure for an Internet of Things (IoT) tunnel area controller device. Background Technology

[0002] The gateway for IoT tunnel area controller equipment is the "nerve center" of the tunnel intelligent system. Its core function is to solve the problems of equipment interconnection, data flow, real-time control and security in the special environment of the tunnel, and to provide key support for the efficient operation, safety monitoring and intelligent decision-making of the tunnel.

[0003] When wiring existing IoT tunnel area controller devices using gateway structures, the wire ends need to be inserted into terminals inside the gateway, and then screws on the top of the terminals are tightened using a screwdriver or similar device. The screws spiral down to clamp the wire ends inside the terminals. Since the terminal group inside the gateway has several wiring holes, tightening the corresponding screws in each hole requires tightening them sequentially, resulting in a high workload of repetitive wiring work. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gateway structure for IoT tunnel area controller devices, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gateway structure for an IoT tunnel area controller device, comprising a gateway housing and a terminal assembly. The gateway housing has a wiring cavity inside. The terminal assembly includes a terminal piece disposed inside the wiring cavity, with a vertical hole at the top of the terminal piece and a wiring hole on the side of the terminal piece. An electromagnetic plate is slidably connected inside the vertical hole. A transmission plate is disposed below the electromagnetic plate, and a sliding rod is connected to the bottom of the transmission plate. The bottom end of the sliding rod passes through the bottom of the vertical hole and is fixed with a clamping plate. A cover plate is provided on the top surface of the wiring cavity, and a medium tube is disposed at the bottom of the cover plate. An elastic piston rod passes through the bottom end of the medium tube.

[0006] Furthermore, the terminal pieces are arranged in two rows, and the two rows of terminal pieces are distributed in a stepped manner inside the wiring cavity.

[0007] Furthermore, the wiring hole and the vertical hole are interconnected, and the wiring hole and the vertical hole are distributed perpendicularly to each other.

[0008] Furthermore, the top opening diameter of the vertical hole is smaller than its bottom diameter, and the bottom outer diameter of the electromagnetic sheet is larger than the top opening diameter of the vertical hole.

[0009] Furthermore, a first threaded hole is provided on the side surface of the cover plate, and a second threaded hole is provided on the side surface of the top surface of the wiring cavity, and bolts are internally threaded to the second threaded hole and the first threaded hole.

[0010] Furthermore, a plug-in port is provided on one side of the wiring hole, parallel to the vertical plane of the wiring cavity, and the plug-in ports are arranged side by side in parallel.

[0011] Furthermore, a pipeline is embedded inside the cover plate, and the top of the medium pipe is connected to the pipeline.

[0012] Furthermore, the end of the pipeline away from the medium pipe is connected to a port wiring anti-disconnection component, and the port wiring anti-disconnection component includes a medium box, with a transmission telescopic rod passing through the side of the medium box.

[0013] Furthermore, the end of the transmission telescopic rod is fixed with a wire clamp, and the wire clamps are arranged in groups of two and symmetrically distributed about the central axis of the insertion port.

[0014] Furthermore, the shape of the opposite side structure of the clamp is adapted to the opening shape of the plug-in port.

[0015] This invention provides a gateway structure for an IoT tunnel area controller device, which has the following advantages:

[0016] 1. The IoT tunnel area controller device uses a gateway structure. When the device wire ends are inserted into the wiring holes and clamped, the repulsive force generated by the energized electromagnetic plate is used for initial clamping. Then, the cover plate is fixed with bolts so that the bottom of the elastic piston rod is attached to the surface of the electromagnetic plate and pushed down. This allows the electromagnetic plate to push against the transmission plate in the de-energized state, further clamping each wire end on the basis of the initial clamping. During this process, there is no need to frequently tighten the screws inside the vertical holes, which greatly reduces the cumbersomeness of connecting multiple wire ends to terminals and greatly reduces the repetitiveness of manually tightening the screws used to clamp the wire ends.

[0017] 2. The IoT tunnel area controller device uses a gateway structure. After the cover plate is closed and fixed, the elastic piston rod pushes down the electromagnetic plate to make the clamping effect of the wire clamping plate on the wire end reach its limit. The excess part of the elastic piston rod retracts into the medium tube to promote the flow of air medium, thereby pushing the transmission telescopic rod to extend. This causes the wire clamps to come closer to each other to clamp the wire at the rear end of the plug inserted into the plug port. This strengthens the plug-to-plug connection structure to prevent the plug from coming loose. Attached Figure Description

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] like Figures 1-5As shown, the present invention provides a technical solution: a gateway structure for an IoT tunnel area controller device, including a gateway housing 1 and a terminal assembly 3. The gateway housing 1 has a wiring cavity 2 inside. The terminal assembly 3 includes a terminal piece 301 disposed inside the wiring cavity 2. A vertical hole 302 is formed at the top of the terminal piece 301, and a wiring hole 303 is formed on the side of the terminal piece 301. An electromagnetic plate 304 is slidably connected inside the vertical hole 302. A transmission plate 305 is disposed below the electromagnetic plate 304, and a sliding rod 306 is connected to the bottom of the transmission plate 305. The bottom end of the sliding rod 306 passes through the bottom of the vertical hole 302 and is fixed with a clamping plate 307. The top cover of the wiring cavity 2... A cover plate 4 is provided, and a medium tube 5 is provided at the bottom of the cover plate 4. An elastic piston rod 6 is provided at the bottom end of the medium tube 5. Two rows of terminal pieces 301 are provided, and the two rows of terminal pieces 301 are distributed in a stepped manner inside the wiring cavity 2. The wiring hole 303 and the vertical hole 302 are interconnected and are perpendicular to each other. The top opening diameter of the vertical hole 302 is smaller than its bottom diameter, and the bottom outer diameter of the electromagnetic plate 304 is larger than the top opening diameter of the vertical hole 302. A first threaded hole 7 is provided on the side surface of the cover plate 4, and a second threaded hole 8 is provided on the side surface of the top surface of the wiring cavity 2. Bolts 9 are threadedly connected to the second threaded hole 8 and the first threaded hole 7.

[0026] The specific operation is as follows: the equipment wire is manually inserted into the wiring cavity 2, so that the wire end is inserted into the wiring hole 303. At this time, the corresponding electromagnetic plate 304 is energized and generates a magnetic force of like repulsion with the transmission plate 305. However, since the outer diameter of the electromagnetic plate 304 is larger than the top diameter of the vertical hole 302, the electromagnetic plate 304 cannot be lifted upward. Therefore, the transmission plate 305 can only push the sliding rod 306 to carry the clamping plate 307 down to initially clamp the wire end. The vertical hole 302 is made of ceramic material, which has a magnetic shielding effect to prevent the magnetism generated by the electromagnetic plate 304 after being energized from affecting the normal operation of the gateway.

[0027] After all wire ends are inserted and initially clamped, cover plate 4 is placed on so that the first threaded hole 7 and the second threaded hole 8 on its surface coincide. At this time, the bottom of the elastic piston rod 6 is located on the upper surface of each electromagnetic plate 304 and is set in a one-to-one manner. Then, tighten the bolt 9. Under the tightening action of the bolt 9, cover plate 4 is tightly attached to the top surface of wiring cavity 2. At this time, the elastic piston rod 6 pushes against the electromagnetic plate 304 under the action of the spring and the air medium inside the medium tube 5. At this time, the electromagnetic plate 304 is de-energized. Under the downward pushing action of the elastic piston rod 6, the electromagnetic plate 304 slides down and pushes the transmission plate 305 down to improve the clamping effect of the clamping plate 307 on the wire ends.

[0028] Based on the above description, when the device wire ends are inserted into the wiring hole 303 and clamped, the present invention utilizes the repulsive force generated by the energized electromagnetic plate 304 for initial clamping. Then, the cover plate 4 is fixed by the bolt 9 so that the bottom of the elastic piston rod 6 is attached to the surface of the electromagnetic plate 304 and pushed down, so that the electromagnetic plate 304 pushes against the transmission plate 305 in the de-energized state, further clamping each wire end on the basis of the initial clamping. During this process, there is no need to frequently tighten the screws inside the vertical hole 302, which greatly reduces the cumbersomeness of connecting multiple wire ends to terminals and greatly reduces the repetitiveness of manually tightening the screws used to clamp the wire ends.

[0029] like Figures 1-5 As shown, a plug-in port 10 is provided parallel to the vertical plane of the wiring cavity 2 on one side of the wiring hole 303, and the plug-in ports 10 are arranged side by side. A pipeline is embedded inside the cover plate 4, and the top end of the medium tube 5 is connected to the pipeline. The end of the pipeline away from the medium tube 5 is connected to the port wiring anti-disconnection component 11. The port wiring anti-disconnection component 11 includes a medium box 1101. A transmission telescopic rod 1102 is provided through the side of the medium box 1101. A wire clamp 1103 is fixed at the end of the transmission telescopic rod 1102. The wire clamps 1103 are arranged in groups of two and symmetrically distributed about the central axis of the plug-in port 10. The structural shape of the opposite side of the wire clamp 1103 is adapted to the opening shape of the plug-in port 10.

[0030] The specific operation is as follows: When wiring the terminals, the wire with the plug can be inserted into the plug port 10. When the cover plate 4 is vertically lowered and placed on the top surface of the wiring cavity 2 and fixed by the bolt 9, the wire clamp 1103 is located on both sides in front of the plug port 10 due to the vertical descent. This allows the side of the wire clamp 1103 closest to the plug port 10 to be against the back side of the wire plug. When the elastic piston rod 6 pushes down the electromagnetic plate 304 to make the clamping effect of the wire clamping plate 307 on the wire end reach its limit, the excess part of the elastic piston rod 6 retracts into the medium tube 5, thereby pushing the air medium or liquid medium (preferably liquid medium) from the medium tube 5 into the medium box 1101 along the pipeline, thereby pushing the transmission telescopic rod 1102 to extend, so that the relative Two wire clamps 1103 are positioned close to each other to clamp the wires at the rear of the plug. The distance between the wire clamps 1103 and the plug-in port 10 is adapted to the size of the exposed part of the plug after it is plugged in. Since the plug and the plug-in port 10 move along the Y-axis to achieve plugging and unplugging, while the wire clamps 1103 translate along the X-axis, the plugging structure of the plug and the plug-in port 10 can be reinforced to prevent the plug from coming loose. The downward pressure of the elastic piston rod 6 on the electromagnetic plate 304 and the extension distance of the wire clamps 1103 are matched to ensure that the elastic piston rod 6 can provide sufficient pressure for the clamping plate 307 to clamp the wire end, and at the same time ensure that the wire clamps 1103 can fully clamp the wires at the rear of the plug.

[0031] Based on the above description, after the cover plate 4 is closed and fixed, when the elastic piston rod 6 pushes down the electromagnetic plate 304 to make the clamping effect of the wire clamping plate 307 on the wire end reach the limit, the excess part of the elastic piston rod 6 retracts into the medium tube 5 to promote the flow of air medium, thereby pushing the transmission telescopic rod 1102 to extend, so that the wire clamps 1103 move closer to each other to clamp the wire at the rear end of the plug inserted into the plug-in port 10, thereby strengthening the plug-in structure of the plug and the plug-in port 10 to prevent the plug from coming loose.

[0032] In summary, the IoT tunnel area controller device uses a gateway structure. During use, the device wires are first manually inserted into the wiring cavity 2, so that the wire ends are inserted into the wiring holes 303. At this time, the corresponding electromagnetic plate 304 is energized and generates a magnetic force that repels the like poles with the transmission plate 305. However, since the outer diameter of the electromagnetic plate 304 is larger than the top diameter of the vertical hole 302, the electromagnetic plate 304 cannot be lifted upwards. Therefore, the transmission plate 305 can only push the sliding rod 306 to carry the clamping plate 307 down to initially clamp the wire ends. The vertical hole 302 is made of ceramic material, which has a magnetic shielding effect to prevent the magnetism generated by the electromagnetic plate 304 after being energized from affecting the normal operation of the gateway.

[0033] After all wire ends are inserted and initially clamped, cover plate 4 is placed on so that the first threaded hole 7 and the second threaded hole 8 on its surface coincide. At this time, the bottom of the elastic piston rod 6 is located on the upper surface of each electromagnetic plate 304 and is set in a one-to-one manner. Then, tighten the bolt 9. Under the tightening action of the bolt 9, cover plate 4 is tightly attached to the top surface of wiring cavity 2. At this time, the elastic piston rod 6 pushes against the electromagnetic plate 304 under the action of the spring and the air medium inside the medium tube 5. At this time, the electromagnetic plate 304 is de-energized. Under the downward pushing action of the elastic piston rod 6, the electromagnetic plate 304 slides down and pushes the transmission plate 305 down to improve the clamping effect of the clamping plate 307 on the wire ends.

[0034] When wiring the terminals, the wire with the plug can be inserted into the plug port 10. When the cover plate 4 is vertically lowered and placed on the top surface of the wiring cavity 2 and fixed by the bolt 9, the wire clamp 1103 is located on both sides in front of the plug port 10 due to the vertical descent. The side of the wire clamp 1103 closest to the plug port 10 is attached to the back side of the wire plug. When the elastic piston rod 6 pushes down the electromagnetic plate 304 to make the clamping effect of the wire clamping plate 307 on the wire end reach the limit, the excess part of the elastic piston rod 6 retracts into the medium tube 5, so as to push the air medium from the medium tube 5 into the medium box 1101 along the pipeline, thereby pushing the transmission telescopic rod 1102 to extend, so that the two relatively distributed wire clamps 1103 move closer to each other, thereby clamping the wire at the back of the plug.
