Description

Technical Field

[0001] The utility model belongs to the technical field of gateway equipment protection equipment, and specifically relates to a protection device for an industrial Internet gateway. Background Art

[0002] A gateway is also called an internetwork connector or a protocol converter. It realizes network interconnection above the network layer. It is a complex network interconnection device that is only used for interconnection between two networks with different high-level protocols.

[0003] Traditional gateways need to be connected to wiring harnesses when in use. During long-term use, the plugged wiring harnesses are prone to loosening and falling off. Loose wiring harnesses can easily cause the ends of the wiring harnesses to bend, affecting their service life. The protection effect on gateway devices is also average, and there is a risk of damage due to bumps. In the prior art, for example, patent application number CN215581509U is a gateway routing device with a protective device, which discloses an upper opening of a protective box, a cover plate is arranged in the opening, and the opening is sealed; a wiring port is arranged on the back side of the gateway routing box, and a power cord, a network cable, and a USB cable are connected to the corresponding wiring ports; a wire threading groove is arranged on the side of the protective box, and the power cord, the network cable, and the USB cable are discharged from the wire threading groove. Each wiring harness passes directly through the wire threading trough. Due to the large number of wire sources and their heavy weight, the ends of the wire harnesses passing through the wire threading trough will be bent, especially the wire harnesses that are directly in contact with the wire threading trough are the most severely bent. Moreover, the friction between the wire harnesses and the wire threading trough of the steel structure will cause wear to the wire harnesses, and long-term use will easily cause damage to the wire harnesses. Therefore, the prior art lacks a structure for corresponding protection of the wire harnesses, which can not only ensure the centralized collection of the wire harnesses, but also avoid bending of the ends of the wire harnesses passing through the protective device.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0036] In addition, in the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description of reference terms such as "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. In the prior art, a wire threading groove is provided on the side of the protective box, and the power cord, network cable, and USB cable are discharged from the wire threading groove. Each wiring harness passes directly through the wire trough. Due to the large number of wire sources and their heavy weight, the ends of the wiring harness passing through the wire trough will bend, especially the wiring harness that is directly in contact with the wire trough will be the most severely bent. Moreover, the friction between the wiring harness and the wire trough of the steel structure will cause wear to the wiring harness, which can easily cause damage to the wiring harness after long-term use. Therefore, the prior art lacks a structure for corresponding protection of the wiring harness, which can not only ensure the centralized collection of the wiring harness, but also prevent the ends of the wiring harness from bending when passing through the protective device. In order to avoid the above problems, the present application designs a protective device for industrial Internet gateways, which can support and protect the wiring harness at the position where the wiring harness extends out of the wire trough. It not only protects the wiring harness so that the wiring harness can pass through the wire trough smoothly after being centrally stored, but also protects the wiring harness from wear and tear between the wiring harness and the wire trough or bending and damage of the wiring harness relative to the wire trough.

[0039] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0040] The utility model relates to a protective device for an industrial Internet gateway, such as Figure 1-4 As shown, it includes a protective box body 1; the protective box body 1 is provided with a threading hole 11; the protective box body 1 has a side with the threading hole 11 connected to a harness clamping assembly 2; the harness clamping assembly 2 includes a clamping assembly 22 relatively movable along the radial direction of the threading hole 11; the clamping assembly 22 is connected to a clamping member 223 for clamping the harness on the side facing the threading hole 11.

[0041] After the gateway device is placed in the placement box 3 described below, the wiring harness of the gateway device passes through the wire threading hole 11 and extends to the outside. A wiring harness clamping assembly 2 is connected to the outer side of the protective box body 1 at a position corresponding to the position where the wiring harness extends out of the wire threading hole 11. After the wiring harness passes through the outside of the wire threading hole 11, it extends into the wiring harness clamping assembly 2. Multiple wiring harnesses are clamped and fixed by the wiring harness clamping assembly 2. The wiring harness clamping assembly 2 also supports the wiring harness, so that the wiring harness can extend parallel to the outside of the wire threading hole 11, that is, the extension direction of the wiring harness remains parallel to the axis of the wire threading hole 11, so that the wiring harness will not bend at a certain angle relative to the wire threading hole 11; and, by supporting the wiring harness with the wiring harness clamping assembly 2, a gap of a certain distance can be generated between the wiring harness and the wire threading hole 11, protecting the wiring harness from contact with the wall of the wire threading hole 11, causing friction between the wiring harness and the inner wall of the wire threading hole 11, resulting in wear of the wiring harness, further improving the service life of the entire gateway device.

[0042] like Figure 1 and Figure 2 As shown, in order to reduce the looseness and bending of the wiring harness port, the wiring harness clamping assembly 2 also includes a fixing assembly 21; the fixing assembly 21 is connected to the protective box body 1, the clamping assembly 22 is slidably connected to the fixing assembly 21, and the ends of the clamping assembly 22 extend out of the fixing assembly 21 respectively.

[0043] The fixing component 21 of the wire harness clamping component 2 is fixedly connected to the protective box body 1, and the clamping component 22 can be connected to the protective box body 1 through the stable fixing component 21. The clamping component 22 is slidably connected inside the fixing component 21 and moves relatively along the radial direction of the threading hole 11; and the clamping component 22 extends out of the fixing component 21 toward one side of the threading hole 11 to facilitate clamping of the wire harness, and the wire harness in the threading hole 11 is clamped on both sides by the two clamping components 22 that move relative to each other.

[0044] The installation position of the fixing assembly 21 of the present application can have multiple implementations, including but not limited to the following implementations proposed in the present application:

[0045] As one of the preferred embodiments, the fixing components 21 are symmetrically arranged along the radial direction of the threading hole 11. The fixing components 21 are symmetrically arranged on both sides of the threading hole 11 along the radial direction of the threading hole 11 with the center of the threading hole 11 as the center, and the fixing components 21 located on both sides of the threading hole 11 are respectively connected to the corresponding clamping components 22, that is, each clamping component 22 is correspondingly slidably connected to a fixing component 21, and the fixing component 21 is a split structure.

[0046] In this embodiment, the fixing components 21 can be symmetrically arranged along the radial direction of the threading hole 11, and the fixing components 21 are distributed vertically, such as Figure 1-2 As shown, the fixing components 21 are symmetrically arranged in a vertical plane with the threading hole 11 as the center. At this time, the wire harness is positioned between the upper and lower fixing components 21 after passing through the threading hole 11;

[0047] In this embodiment, the fixing component 21 can also be set with a certain inclination angle relative to the horizontal plane with the wire threading hole 11 as the center. It is worth noting that at this time, in order to be able to fully support the wiring harness, that is, the clamping member 223 can wrap the wiring harness, it is necessary to increase the area of ​​the clamping member 223, and an arc-shaped action surface is provided on one side of the clamping member 223 for clamping the wiring harness. The arc-shaped action surfaces between the clamping members 223 on both sides can be matched to prevent the wiring harness from falling between the two clamping members 223.

[0048] As another preferred embodiment, the fixing component 21 is arranged along one side of the threading hole 11 in the radial direction. The fixing component 21 is centered on the center of the threading hole 11 and is symmetrically arranged on one side of the threading hole 11 in the radial direction of the threading hole 11; when the fixing component 21 is arranged along one side of the threading hole 11, the fixing component 21 can be a split structure or an integral structure, because even if the fixing component 21 is an integral structure, since the fixing component 21 is located on one side of the threading hole 11, it will not block the threading hole 11 and will not hinder the extension of the wire harness.

[0049] The fixing assembly 21 includes a fixing member 211 and a fixing tube 212 ; the fixing member 211 is connected to the protection box body 1 ; a fixing tube 212 extending along the radial direction of the threading hole 11 is vertically connected inside the fixing member 211 .

[0050] There is no specific restriction on the structure of the fixing member 211, which may be a flat structure, a block structure, or a U-shaped structure. When it is a flat structure, the shape is also not specifically limited, and it may be a structure with an arc surface on the side facing the outside of the protective box body 1, a rectangular structure, or a triangular structure.

[0051] The purpose of the fixing part 211 is to support the clamping assembly 22, so the fixing part 211 needs to be fixedly connected to the outer side of the protective box body 1; the fixing tube 212 is a cylindrical structure, and the interior of the fixing tube 212 is a hollow structure, the purpose of which is to facilitate the sliding connection of the sliding rod 221 described below in the fixing tube 212, the fixing tube 212 is fixedly connected to the fixing part 211, and the fixing tube 212 and the fixing part 211 are in a vertical connection relationship, the fixing tube 212 is installed and fixedly connected to the fixing part 211, and the two sides of the fixing tube 212 extend out of the fixing part 211, and the sliding rod 221 described below is slidably connected in the fixing tube 212, and the fixing tube 212 serves as a moving channel for the sliding rod 221. On the one hand, it can limit the sliding rod 221, and on the other hand, it can also extend the moving distance of the sliding rod 221, to ensure that the sliding rod 221 always maintains a linear motion and will not deviate in the fixing assembly 21 to cause the wiring harness to be clamped.

[0052] The structure of the clamping assembly 22 is not limited to the structures listed in this application, and any one of the following embodiments may be adopted:

[0053] As a preferred embodiment, the clamping assembly 22 includes a sliding rod 221; the sliding rod 221 extends into the fixed cylinder 212 and is slidably connected to the fixed cylinder 212, and the sliding rod 221 extends out of the fixed cylinder 212 on a side close to the threading hole 11 to connect to the clamping member 223; a return spring 222 is connected between the sliding rod 221 and the inner wall of the fixed cylinder 212.

[0054] The clamping members 223 on both sides are spaced apart by a preset distance in order to reserve space for accommodating the wiring harness. Only when there are many wiring harnesses will the wiring harnesses squeeze the clamping members 223 , and the space reserved for accommodating the wiring harnesses is the placement space.

[0055] The clamping components 22 arranged on both sides of the threading hole 11 are used to clamp the wire harness, wherein the structure directly contacting the wire harness is the clamping piece 223, which can move along the axial direction of the fixed cylinder 212 under the movement of the sliding rod 221, that is, move along the radial direction of the threading hole 11, and the sliding rod 221 moves toward the threading hole 11 to drive the clamping piece 223 to move toward the wire harness, thereby clamping the wire harness; a return spring 222 is sleeved on the outer side of the sliding rod 221, one end of the return spring 222 is connected to the sliding rod 221, and the other end of the return spring 222 is connected to the inner wall of the fixed cylinder 212; the wire harness passes through the threading hole 11, and if the volume of multiple wire harnesses is smaller than the placement space between the clamping pieces 223 on both sides, the multiple wire harnesses are directly extended to the outside through the clamping piece 223, and the wire harness can The wire harness is in an unclamped state in the placement space of the clamping piece 223, but the wire harness can be positioned in the clamping assembly 22, and the clamping piece 223 supports the wire harness so that the wire harness remains parallel to the threading hole 11 and has a certain gap from the threading hole 11, thereby avoiding wear between the threading hole 11 and avoiding bending relative to the threading hole 11; when the wire harness is larger than the reserved placement space, in order to smoothly pass the wire harness between the clamping pieces 223, it is necessary to move the slide bar 221 toward the side away from the threading hole 11 to increase the placement space. At this time, the return spring 222 between the slide bar 221 and the fixed cylinder 212 is compressed, and the return spring 222 will exert a reaction force on the wire harness, so that the wire harness is subjected to an extrusion force, so that the wire harness is clamped by the clamping pieces 223 on both sides.

[0056] In this embodiment, the structure of the sliding rod 221 is not specifically limited, and may include but not be limited to the following embodiments:

[0057] As a preferred embodiment, Figure 4 As shown, the sliding rod 221 includes a rod body 2211 and a slip ring 2212; the outer side of the rod is connected to the slip ring 2212, and the slip ring 2212 is slidably connected in the fixed cylinder 212; a return spring 222 is connected between the slip ring 2212 and the inner wall of the fixed cylinder 212;

[0058] The rod body 2211 is a T-shaped structure. The part of the rod body 2211 that extends into the fixed cylinder 212 is an optical axis structure. The rod body 2211 on one side outside the fixed cylinder 212 has a disc-shaped structure, which is used as a handle of the slide bar 221 to facilitate the user to operate the slide bar 221; the slip ring 2212 is sleeved and fixedly connected to one end of the rod body 2211. The slip ring 2212 is a circular ring structure. The outer circumference of the slip ring 2212 is slidably connected to the inner wall of the fixed cylinder 212. The reset spring 222 is sleeved on the outside of the rod body 2211. The slip ring 2212 is connected to the rod body 2211 so that the rod body 2211 A step surface is formed on the upper surface, one end of the return spring 222 is connected to the step surface, and the other end is connected to the fixed tube 212; when in use, the clamping piece 223 moves away from the threading hole 11 under the extrusion of the wiring harness, so that the slip ring 2212 and the slide rod 221 move together in the fixed tube 212 toward the side away from the threading hole 11. At this time, the return spring 222 is stretched, and pressure is applied to the clamping piece 223 under the reaction force of the return spring 222. The clamping piece 223 achieves balance under the extrusion force of the wiring harness and the reaction force of the return spring 222, so that the wiring harness is positioned between the clamping pieces 223.

[0059] As another embodiment, the sliding rod 221 includes a rod portion and a protruding portion; the protruding portion protrudes toward the outer circumferential surface of the rod portion and is connected to the rod portion to form an integrated structure, and a return spring 222 is connected between the protruding portion and the inner wall of the fixed tube 212.

[0060] In this embodiment, the sliding rod 221 is an integrated structure. The rod portion of the sliding rod 221 is a T-shaped structure, and the raised portion is a circular ring structure. The raised portion is located on one side of the rod portion. The raised portion can slide along the inner wall of the fixed tube 212. The purpose of the raised portion protruding from the outer circumferential surface of the rod portion is to facilitate the connection of one end of the reset spring 222. The other end of the reset spring 222 is connected to the inner wall of the fixed tube 212.

[0061] As another preferred embodiment, the clamping assembly 22 includes a sliding rod; the sliding rod extends along the axial direction of the fixed cylinder 212 and is threadedly connected to the fixed cylinder 212, and the sliding rod extends out of the fixed cylinder 212 on one side close to the threading hole 11 and is connected to the clamping member 223.

[0062] The sliding rod is threadably connected to the fixed tube 212. The sliding rod is made to move relative to the fixed tube 212 by screwing the sliding rod. When the wiring harness needs to be clamped, the sliding rod is screwed to move toward one side of the threading hole 11. The distance between the sliding rods on both sides is shortened. When the clamping piece 223 connected to the end of the sliding rod contacts the wiring harness, the screwing is stopped. The positioning of the wiring harness is achieved by moving the sliding rod.

[0063] like Figure 3As shown, the interior of the protective box body 1 is also provided with a placement box 3 for accommodating the gateway device; the placement box 3 is connected to the protective box body 1 through a buffer assembly 4; the placement box 3 includes a placement box body 31, an adjustment rod 32 and a clamping plate 33; the adjustment rod 32 is connected through the length direction of the placement box body 31, and the side of the adjustment rod 32 extending into the interior of the placement box body 31 is connected to the clamping plate 33 for clamping the gateway device.

[0064] The placement box body 31 can be a square structure or a cylindrical structure. The specific shape of the placement box body 31 is not limited by this embodiment. Figure 3 As shown, in the present embodiment, the placement box body 31 adopts a square structure, and the side of the protection door 7 described below of the placement box body 31 facing the protection box body 1 has an opening to facilitate the smooth installation of the gateway device in the placement box body 31 through the opening. Because the space between the top of the placement box body 31 and the top of the protection box body 1 is limited, if the front end of the placement box body 31 does not have an opening, the gateway device may not be able to enter the placement box body 31.

[0065] For ease of description, Figure 3 The orientation shown in the figure is described, through holes are symmetrically provided at the left and right ends of the placement box body 31, and the adjusting rod 32 is symmetrically slidably connected in the through holes. One end of the adjusting rod 32 passes through the through hole and extends into the placement box body 31. One end of the adjusting rod 32 located inside the placement box body 31 is rotatably connected to the clamping plate 33. By adjusting the moving distance of the adjusting rod 32 relative to the gateway device inside the placement box body 31, the clamping plate 33 connected to the adjusting rod 32 is clamped relative to the two sides of the gateway device, thereby realizing effective positioning of the gateway device.

[0066] The purpose of providing a buffer assembly 4 at the bottom of the placement box body 31 is to protect the placement box body 31 from rigid collision with the protection box body 1, which causes the placement box body 31 to shake left and right inside the protection box body 1 and causes the placement box body 31 to touch the protection box body 1, resulting in friction damage between the two.

[0067] As a preferred embodiment, the buffer assembly 4 includes a telescopic member 41 and a buffer spring 42 connected between the bottom of the placement box 3 and the bottom of the protection box body 1 ; the buffer spring 42 is sleeved on the outside of the telescopic member 41 .

[0068] When the gateway device is installed in the placement box 31, the adjustment rod 32 moves inward, driving the clamping plate 33 to clamp the two sides of the gateway device. Since the gateway device has a certain weight, the gateway device will drive the placement box 31 to move toward the bottom of the protection box 1. Due to the uneven weight distribution, the placement box 31 may be tilted in the protection box 1. Under the action of the buffer component 4, the elastic connection between the placement box 31 and the protection box 1 can be maintained, and the placement box 31 can be kept in a balanced state to avoid tilting, so that the gateway device can be positioned and buffered.

[0069] As a preferred embodiment, Figure 2-4 As shown, the clamping member 223 is provided with an arc groove 5 on one side facing the threading hole 11, so that the wire harness is embedded in the arc groove 5. The arc groove is used to accommodate the wire harness, and the arc groove has an arc-shaped action surface that can reduce the friction between the wire harness and the wire harness.

[0070] like Figure 1 As shown, the gateway protection device also includes a heat dissipation net 6, which is connected to the side of the protection box body 1 opposite to the protection door 7 described below; the protection door 7 is hingedly connected to the protection box body 1, and the gateway device is installed inside the placement box body 31 by opening the protection door 7. In addition, a mounting frame 8 is also connected to the outside of the protection box body 1, and the mounting frame 8 is symmetrically arranged on the top of the protection box body 1. The mounting frame 8 is provided with a mounting hole 9, and the protection box body 1 is installed as a whole on a platform or a wall through the mounting hole 9 and bolts for fixing. In addition, in order to increase the overall strength, reinforcing ribs 10 are provided on the outer circumferential surface of the protection box body 1, and the reinforcing ribs 10 are symmetrically arranged and arranged in a square shape.

[0071] Working principle: When in use, the whole is installed and fixed through the mounting hole 9 on the mounting frame 8, the protective door 7 is opened, the gateway device is placed in the placement box 3, and the two sets of adjustment rods 32 are rotated. The rotation of the adjustment rods 32 causes the clamping plate 33 to move toward the outer wall of the gateway until the outer wall of the gateway is clamped and fixed. When the whole is transferred or collided during use, the placement box 3 applies pressure to the buffer spring 42 to deform the buffer spring 42 and the telescopic member 41 contracts to provide buffer protection for the gateway device, thereby increasing the protection of the gateway device. In order to achieve the protective effect, the wiring harness connected to the gateway is connected to the gateway device through the wire threading hole 11, the slide bar 221 is lifted to deform the reset spring 222 under force, and then one end of the wiring harness is passed through the middle position of the clamping piece 223, and the slide bar 221 is released. The slide bar 221 slides under the action of the reset spring 222, and the clamping piece 223 clamps and fixes the wiring harness, which can increase the connection strength between the wiring harness and the gateway, and avoid the wiring harness port from loosening or falling off, and the wiring harness end bending caused by loose wiring harness.
