Description

Technical Field

[0001] This invention relates to the field of gateway box technology, and more particularly to a gateway specifically designed for a security inspection IoT platform. Background Technology

[0002] A dedicated gateway for a security inspection IoT platform is an intelligent communication hub device designed for security inspection scenarios. Its core function is to achieve heterogeneous data fusion and collaborative management between security inspection equipment (such as X-ray machines, metal detectors, CT scanners, etc.) and the IoT platform. The main body of the gateway is the gateway host, which needs to be connected via a network cable.

[0003] Traditional gateway hosts are mostly RJ45 connectors with direct plug-in connectors. During daily use or installation, if the network cable is accidentally pulled (the network cable connected to the security inspection IoT platform mainly runs on the ground, and security personnel may easily kick the network cable when walking over it, causing it to be pulled), the crimped point between the network cable core and the RJ45 connector is the stress point and is easily broken, affecting the normal communication of the device. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of traditional gateway hosts in the prior art, where the crimping point between the network cable core and the RJ45 connector is a stress point that is easily broken, affecting the normal communication of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gateway specifically for a security inspection IoT platform, comprising a gateway host, a cable reel, a redundant tube, and an interface card. The gateway host has multiple network cable interfaces on its back, and the interface card is fitted into the network cable interfaces for engaging the network cable connectors. A cable reel is rotatably mounted inside the cable reel for winding network cables. A drive gear is fixedly mounted at one end of the shaft of the cable reel, and a cover plate is fixedly mounted at one end of the cable reel. The redundant tube is fixedly connected to the back of the cable reel. The invention also includes: An anti-pull assembly installed on the cable reel to lock the reel roller when the network cable is pulled rapidly, the anti-pull assembly including a ratchet, a locking seat and a pawl seat; A redundant component installed inside the redundant tube is used to press the network cable inside the redundant tube into an "S" shape and straighten the network cable when it is pulled. The redundant component includes a pressing frame, a transmission frame and a drive disk. Two baffles, mirror-image movable, are inserted into the redundant tube at the end away from the cable reel to prevent the network cable connector from retracting into the redundant tube.

[0006] In at least some embodiments, a locking button is rotatably mounted on the cover plate. The locking button is inserted into the shaft of the winding roller. An axial protrusion is provided on the shaft of the locking button, and a corresponding engaging groove is provided on the inner wall of the shaft of the winding roller. The rotation of the winding roller drives the locking button to rotate. A spring is installed between the locking button and the cover plate. An annular friction plate is provided on the cover plate. Pressing the locking button contacts the annular friction plate to lock the winding roller.

[0007] In at least some embodiments, the ratchet is rotatably mounted on the cover plate, a driven gear that meshes with the driving gear is fixedly mounted on the shaft of the ratchet, a snap-fit ​​plate is fixedly mounted on the shaft of the ratchet, a snap-fit ​​hook is rotatably mounted on the snap-fit ​​plate, the snap-fit ​​seat is fixedly mounted on the cover plate, a slider is rotatably slidably mounted on the snap-fit ​​seat and the slider is in the shape of an arc concentric with the ratchet, a pawl seat is rotatably mounted on the snap-fit ​​seat, a first limiting groove is provided on the pawl seat, and a first protrusion is provided on the slider that is movably engaged in the first limiting groove.

[0008] In at least some embodiments, a first return spring is rotatably connected between the middle of the hook and the locking plate. When the ratchet rotates rapidly, the centrifugal force of the hook overcomes the elastic force of the first return spring and is thrown out. The hook drives the slider to slide and drives the pawl seat to rotate and engage with the ratchet through the first protrusion.

[0009] In at least some embodiments, both the card holder and the card plate are provided with limiting protrusions to limit the rotation angle of the pawl seat and the hook, so as to prevent the pawl seat and the hook from reversing.

[0010] In at least some embodiments, multiple pressure frames are provided and movably inserted into the redundant tube at vertical intervals. Two transmission frames are provided and are respectively inserted into the vertically and vertically arranged pressure frames. Pressure rollers are rotatably installed on the pressure frames to press the network cables. The drive disk is rotatably installed on the redundant tube. The drive disk has an inclined second limiting groove. Both transmission frames have a second protrusion that is movably engaged with the second limiting groove. The rotation of the drive disk drives the transmission frames to rise and fall. A torsion spring is installed between the axis of the drive disk and the redundant tube. The elastic force of the torsion spring keeps the pressure frames in the pressure state.

[0011] In at least some embodiments, a lead screw sleeve is horizontally slidably mounted on the redundant tube, and a small adjusting lead screw threadedly connected to the lead screw sleeve is rotatably mounted on the redundant tube. A roller is rotatably mounted on one end of the lead screw sleeve, and rotating the small adjusting lead screw causes the lead screw sleeve to move horizontally, so that the roller on the lead screw sleeve pushes the drive disk to rotate, thereby moving the wire crimping frames away from each other, facilitating the passage of the network cable RJ45 connector during installation.

[0012] In at least some embodiments, the drive disk is fan-shaped and does not interfere with the lead screw sleeve during rotation.

[0013] In at least some embodiments, a spring is fixedly connected between the baffle and the redundant tube, and the baffle is pushed outward under the action of elastic force. The top of the baffle is arc-shaped and the interface card is provided with a ramp. After the network cable RJ45 connector is inserted into the gateway host, the ramp on the interface card pushes the baffle inward to lock the network cable horizontal connector.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by adding an anti-pull component, when the network cable is subjected to a sudden pulling force, the winding roller rotates rapidly. Under the action of centrifugal force, the hook overcomes the elastic force of the first return spring and throws outward, pushing the slider to slide along the arc-shaped guide rail of the card seat. Finally, it drives the drive pawl seat to complete a small-angle deflection in a short time and form a mechanical interlock with the tooth groove of the ratchet, effectively preventing the disconnection of the crystal head contact point during the sudden pulling process.

[0015] 2. In this invention, by adding redundant components, in the initial state, the torsion spring applies a preload force, causing the upper and lower pressure frames to press the wire into an "S" shape. When under tension, the wire straightens and pushes the pressure roller to move. The second protrusion of the transmission frame slides along the second limiting groove, and the drive disc rotates to compress the torsion spring, forming a progressive resistance, which effectively reduces the stress at the contact point of the crystal head during sudden pulling.

[0016] In summary, by adding anti-pull components and redundant components, and coordinating with the slope angle of the baffle to ensure that the RJ45 connector is automatically pressed and closed when inserted, the baffle is prevented from shrinking inward. This forms a triple protection system of centrifugal ratchet locking, "S"-shaped redundant buffer, and mechanical limit of the baffle, which works synergistically to improve the gateway host's resistance to impact and pull, and reduce the stress burden at the crimping point between the network cable core and the RJ45 connector.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Implementation examples, based on Figures 1-11The present invention provides a gateway for a security inspection IoT platform, comprising a gateway host 1, a cable reel 2, a redundant tube 3, and an interface card 4, as shown below. Figure 3 As shown, the gateway host 1 has multiple network cable interfaces on its back, and the interface card 4 is installed inside the network cable interfaces to secure the network cable connectors. Figure 5 As shown, a winding roller 201 for winding network cables is rotatably installed inside the winding reel 2. A drive gear 202 is fixedly installed at one end of the shaft of the winding roller 201, and a cover plate 203 is fixedly installed at one end of the winding reel 2. A redundant tube 3 is fixedly connected to the back of the winding reel 2. Figure 1 and Figure 2 As shown, it also includes an anti-pull assembly 5 installed on the cable reel 2 to lock the cable reel roller 201 when the network cable is pulled quickly. The anti-pull assembly 5 includes a ratchet 501, a locking seat 502, and a pawl seat 503. A redundant assembly 6 installed in the redundant tube 3 is used to press the network cable in the redundant tube 3 into an "S" shape and straighten the network cable when it is pulled. The redundant assembly 6 includes a wire pressing frame 601, a transmission frame 602, and a drive disk 603. Two baffles 7 are inserted into the redundant tube 3 at the end away from the cable reel 2 to prevent the network cable RJ45 head from retracting into the redundant tube 3. Before installing the network cable, the network cable is wound on the cable reel roller 201 and the RJ45 head passes through the redundant tube 3. At the same time, excess cable length is left in the redundant tube 3 to ensure that the network cable in the redundant tube 3 is pressed into an "S" shape by the redundant mechanism later.

[0023] like Figure 4 and Figure 5 As shown, a locking button 204 is rotatably mounted on the cover plate 203. The locking button 204 is inserted into the shaft of the winding roller 201. An axial protrusion is provided on the shaft of the locking button 204, and a corresponding engaging groove is provided on the inner wall of the shaft of the winding roller 201. The rotation of the winding roller 201 drives the locking button 204 to rotate. A spring is installed between the locking button 204 and the cover plate 203. An annular friction plate is provided on the cover plate 203. Pressing the locking button 204 contacts the annular friction plate to lock the winding roller 201. Among them, the rotating small adjusting screw 302 drives the screw sleeve 301 to move laterally. The roller at the end of the screw sleeve 301 contacts the inclined surface of the drive disk 603. When the screw sleeve 301 moves the maximum distance laterally, the redundant component 6 unfolds so that the crystal head can pass through smoothly, which is convenient for installation. The installation time is greatly shortened and no special tools are required.

[0024] like Figures 6-8As shown, a ratchet 501 is rotatably mounted on a cover plate 203. A driven gear 504, which meshes with the driving gear 202, is fixedly mounted on the shaft of the ratchet 501. A snap-fit ​​plate 505 is fixedly mounted on the shaft of the ratchet 501, and a snap hook 506 is rotatably mounted on the snap-fit ​​plate 505. A latch 502 is fixedly mounted on the cover plate 203, and a slider 508 is rotatably and slidably mounted on the latch 502, with the slider 508 forming an arc concentric with the ratchet 501. A pawl seat 503 is rotatably mounted on the latch seat 502, and a first limiting groove 511 is provided on the pawl seat 503. The slider 508 has a movable... The first protrusion 509 is locked in the first limiting groove 511. The middle part of the hook 506 is rotatably connected to the locking plate 505. When the ratchet 501 rotates rapidly, the centrifugal force of the hook 506 overcomes the elastic force of the first returning spring 507 and is thrown out. The hook 506 drives the slider 508 to slide and drives the pawl seat 503 to rotate through the first protrusion 509 and engage with the ratchet 501. The locking seat 502 and the locking plate 505 are both provided with limiting protrusions 510 to limit the rotation angle of the pawl seat 503 and the hook 506 to prevent the pawl seat 503 and the hook 506 from reversing. When the network cable is subjected to sudden tension, the winding roller 201 rotates rapidly, driving the drive gear 202 to rotate. This drives the ratchet 501 to rotate faster via the driven gear 504. Centrifugal force causes the hook 506 to overcome the elasticity of the first return spring 507 and be thrown outward, pushing the slider 508 to slide along the arc-shaped guide rail of the card seat 502. The first protrusion 509 of the slider 508 moves within the first limiting groove 511, driving the pawl seat 503 to complete a small-angle deflection in a short time, forming a mechanical interlock with the tooth groove of the ratchet 501. The limiting protrusion 510 limits the maximum rotation angle of the pawl seat 503, avoiding overload damage and effectively preventing the disconnection of the crystal head contact during sudden pulling.

[0025] like Figure 9 and Figure 10As shown, multiple wire pressing frames 601 are provided and are movably inserted into the redundant tube 3 at vertical intervals. Two transmission frames 602 are provided and are respectively inserted into the wire pressing frames 601 arranged vertically. A wire pressing roller 604 is rotatably mounted on the wire pressing frame 601 to press the network cable. A drive disk 603 is rotatably mounted on the redundant tube 3. The drive disk 603 has an inclined second limiting groove 606. Both transmission frames 602 have a second protrusion 605 that is movably engaged with the second limiting groove 606. The rotation of the drive disk 603 drives the transmission frames 602 to rise and fall. A torsion spring 607 is installed between the shaft of the drive disk 603 and the redundant tube 3. The torsion spring 607 keeps the wire clamping frame 601 in a wire clamping state. A screw sleeve 301 is horizontally slidably installed on the redundant tube 3. A small adjusting screw 302, which is threadedly connected to the screw sleeve 301, is rotatably installed on the redundant tube 3. A roller is rotatably installed at one end of the screw sleeve 301. Rotating the small adjusting screw 302 causes the screw sleeve 301 to move horizontally, so that the roller on the screw sleeve 301 pushes the drive disk 603 to rotate, thereby making the wire clamping frames 601 move away from each other, so that the network cable crystal head can pass through during the installation process. The drive disk 603 is fan-shaped and will not interfere with the screw sleeve 301 during the rotation of the drive disk 603. In the initial state, the torsion spring 607 applies a preload, causing the upper and lower pressure frames 601 to press the wire into an "S" shape. When under tension, the wire straightens and pushes the pressure roller 604 to move. The second protrusion 605 of the transmission frame 602 slides along the second limiting groove 606, and the drive disc 603 rotates to compress the torsion spring 607, forming a progressive resistance. After the tension is released, the torsion spring 607 automatically resets and restores the "S"-shaped buffer shape, effectively reducing the stress at the contact point of the crystal head during sudden pulling.

[0026] like Figure 11 As shown, a spring is fixedly connected between the baffle 7 and the redundant tube 3, and the baffle 7 is pushed outward under the action of the elastic force. The top of the baffle 7 is arc-shaped and the interface card 4 is provided with a ramp. After the network cable RJ45 connector is inserted into the gateway host 1, the ramp on the interface card 4 pushes the baffle 7 inward to lock the network cable horizontal connector. The angle of the ramp ensures that the baffle 7 is automatically pressed when the RJ45 connector is inserted to prevent the RJ45 connector from shrinking inward. The baffle 7 can be colored. After the main body of the baffle 7 is pressed into the redundant tube 3, the color disappears. Visual feedback is used to ensure that the network cable RJ45 connector is installed.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
