[0003] Various cables (telephone lines, network cables, optical fibers, data cables, power cables, etc.) are plugged into the network protection safety communication isolation device. The network protection safety communication isolation device in the prior art lacks the function of accommodating the cables, resulting in the various cables plugged into the network protection safety communication isolation device being very messy and the various cables are easily entangled with each other.

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and propose a network protection safety communication isolation device to solve the various problems caused by the lack of cable accommodation function of the existing network protection safety communication isolation device.

[0005] In order to achieve the above technical objectives, the present invention proposes a network protection security communication isolation device, comprising: A box body, a plurality of wiring ports are arranged on the rear side of the box body, and a slide groove extending along the front-rear direction of the box body is arranged on the box body; A sliding frame installed on the rear side of the box body, the sliding frame is slidably connected to the sliding groove, and the sliding frame is provided with a wire passing hole; and at least one wire clamping plate installed in the wire passing hole, and the wire clamping plate is provided with a wire clamping groove for the cable to pass through.

[0006] The network protection safety communication isolation device of the present invention is provided with a sliding frame that can slide relative to the box body on the rear side of the box body, and the sliding frame is provided with a wire passing hole and at least one wire clamping plate arranged in the wire passing hole, so that the cables on the rear side of the box body can be limited in the wire clamping groove of the wire clamping plate in sequence, so that the cables can be better organized and stored, and the mutual entanglement and knotting of the cables can be avoided. At the same time, the sliding frame can slide relative to the box body to change the distance between the sliding frame and the box body, so as to adjust the distance between the sliding frame and the box body according to the number of cables, so as to form a more suitable space for accommodating the cables between the sliding frame and the box body, so that the cables of the network protection safety communication isolation device can be well stored.

[0007] Preferably, the sliding frame includes a sliding frame body and a U-shaped member, the sliding frame body includes an upper beam, a lower beam and two longitudinal columns connected between the upper beam and the lower beam, the U-shaped member includes a bottom plate and two rigid walls formed by extending upward from both ends of the bottom plate, the bottom plate is installed on one of the longitudinal columns, the two rigid walls are abutted on the other longitudinal column, and the wire hole is formed between the bottom plate, the two rigid walls and one of the longitudinal columns.

[0009] Preferably, the U-shaped part also includes a sliding rod, wherein a through groove is opened on one of the rigid walls, and the sliding rod is arranged in the through groove. One end of the sliding rod is fixed to the U-shaped part, and the other end abuts against one of the longitudinal columns. The sliding rod and the wire clamping groove are slidably matched to enable the at least one wire clamping plate to slide laterally in the wire passing hole.

[0010] By adopting the above-mentioned technical solution, the operator can slide the wire clamp to a position that is convenient for operation when threading the wires, which is more convenient for the operator to operate. At the same time, the operator can reasonably distribute the wire clamp in the wire hole after threading the wires, thereby reducing the stress on the cables.

[0018] By adopting the above-mentioned technical solution, the hollow guide rails arranged on the upper and lower sides of the box body and the corresponding sliding parts arranged on the sliding frame make the sliding of the sliding frame relative to the box body more stable, thereby improving the stability of the cables on the sliding frame when the sliding frame slides and reducing the shaking of the cables.

[0020] By adopting the above-mentioned technical solution, the dust filter can be removably installed on the outside of the heat dissipation hole, reducing the risk of external dust and water vapor entering the network protection safety communication isolation device. At the same time, the removable dust filter facilitates the operator to regularly clean and replace the dust filter, thereby avoiding the dust filter being used for too long, resulting in a decrease in the heat dissipation efficiency of the network protection safety communication isolation device.

[0021] Preferably, the upper fixing plate is provided with screw holes for fixing the dustproof filter, and the dustproof filter is provided with screws.

[0022] By adopting the above-mentioned technical solution, the dust filter is detachably fixedly connected to the housing, reducing or avoiding the shaking of the dust filter which causes the gap between the dust filter and the housing to increase and affect the dustproof effect of the dustproof component, thereby improving the stability of the dustproof effect of the dustproof component.

DETAILED DESCRIPTION

[0027] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships 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, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" and "several" mean two or more, unless otherwise clearly specified.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" 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 or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 5 As shown, a network protection safety communication isolation device proposed in an embodiment of the present invention includes a box body 100, a sliding frame 200 and at least one clamping plate 300. A plurality of wiring ports 110 are provided on the rear side of the box body 100, and the plurality of wiring ports 110 are used to connect various cables, such as telephone cables, network cables, data cables, optical fibers, power cables, etc. The box body 100 is provided with a slide groove 121 extending along the front and rear direction of the box body 100, the sliding frame 200 is installed on the rear side of the box body 100, and the sliding frame 200 is slidably connected to the slide groove 121 so that the sliding frame 200 can slide forward and backward on the rear side of the box body 100. A wire hole 230 is provided on the sliding frame 200. At least one clamping plate 300 is installed in the wire hole 230, and a clamping groove 310 for the cable to pass through is provided on the clamping plate 300.

[0032] When arranging and storing the cables at the rear side of the network protection safety communication isolation device, the sliding frame 200 is first pulled out, and a space for arranging the cables is formed between the sliding frame 200 and the box 100. The operator straightens the cables in the space, passes the cables through the wire holes 230 and the wire clamping grooves 310 of the wire clamping plate 300, and then passes out from the rear of the network protection safety communication isolation device. Multiple cables are sequentially limited in the wire clamping grooves 310 of the wire clamping plate 300. Since the sliding frame 200 can slide relative to the box 100, when there are more cables, more cables need to occupy more space, and the operator can pull out more of the sliding frame 200, and there is a larger space between the sliding frame 200 and the box 100 to accommodate more cables; when there are fewer cables, the operator can pull out less of the sliding frame 200, and there is a smaller space between the sliding frame 200 and the box 100 to accommodate fewer cables.

[0033] The cable can also be inserted from the rear of the sliding frame 200, the cable first passes through the clamping groove 310, and then is plugged into the network protection safety communication isolation device through the wire hole 230. After the cable is plugged in, the distance between the sliding frame 200 and the box 100 is adjusted, so that the cable between the sliding frame 200 and the box 100 can be reasonably stored.

[0034] In this embodiment, a plurality of clamping plates 300 may be provided, and the clamping groove 310 of the same clamping plate 300 may be used to limit the position of cables of the same type, or may be used to limit the position of cables of different types.

[0035] The network protection safety communication isolation device of the present invention is provided with a sliding frame 200 that can slide relative to the box body 100 on the rear side of the box body 100, and the sliding frame 200 is provided with a wire hole 230 and at least one wire clamping plate 300 arranged in the wire hole 230, so that the cables on the rear side of the box body 100 can be sequentially limited in the wire clamping groove 310 of the wire clamping plate 300, so that the cables can be better organized and stored, and the mutual entanglement and knotting between the cables can be avoided. At the same time, the sliding frame 200 can slide relative to the box body 100 to change the distance between the sliding frame 200 and the box body 100, so as to adjust the distance between the sliding frame 200 and the box body 100 according to the number of cables, so as to form a more suitable space for accommodating cables between the sliding frame 200 and the box body 100, so that the cables of the network protection safety communication isolation device can be well stored.

[0036] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 5As shown, the sliding frame 200 includes a sliding frame body 210 and a U-shaped member 220, the sliding frame body 210 includes an upper beam 211, a lower beam 212 and two longitudinal columns 213 connected between the upper beam 211 and the lower beam 212, the U-shaped member 220 includes a bottom plate 221 and two rigid walls 222 formed by extending upward from both ends of the bottom, the bottom plate 221 of the U-shaped member 220 is installed on one of the longitudinal columns 213, the two rigid walls 222 abut against the other longitudinal column 213, and a wire hole 230 is formed between the bottom plate 221 of the U-shaped member 220, the two rigid walls 222 and one longitudinal column 213, and the wire hole 230 is substantially square. The clamping plate 300 can be installed on the U-shaped member 220 or on the longitudinal column 213.

[0037] Such a configuration enables the sliding frame body 210 to have good rigidity, thereby preventing the sliding frame 200 from being deformed or damaged during the sliding process.

[0038] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 5 As shown, the U-shaped member 220 further includes a sliding rod 2222. A through slot 2221 is formed on one of the rigid walls 222 of the U-shaped member 220, and the sliding rod 2222 is disposed in the through slot 2221. One end of the sliding rod 2222 is fixed to the U-shaped member 220, and the other end abuts against one of the longitudinal columns 213. The sliding rod 2222 is slidably matched with the clamping groove 310 to enable at least one clamping plate 300 to slide laterally in the wire passing hole 230.

[0039] When the operator passes the cable through the clamping groove 310 of the clamping plate 300, the clamping plate 300 can be slid to the center of the wire hole 230, so that there is more operating space on both the left and right sides of the clamping plate 300, which is convenient for the operator to operate. When there is only one clamping plate 300, the ability of the clamping plate 300 to slide helps to adjust the clamping plate 300 to a reasonable position, so that the cable can be in a more suitable position and avoid excessive stress on the cable. When multiple clamping plates 300 are provided, the clamping plate 300 that has completed threading can be slid to the edge of the wire hole 230, which is more helpful for threading other clamping plates 300. At the same time, after threading, multiple clamping plates 300 can slide to adjust the position of the cables. Since the wire hole 230 is roughly square, the wire hole 230 provides a wider lateral sliding space for the clamping plate 300, thereby improving the space utilization rate of the wire hole 230.

[0040] With such arrangement, the operator can slide the clamp plate 300 to a convenient position for operation when threading the wires, which is more convenient for the operator to operate. At the same time, the operator can reasonably distribute the clamp plate 300 after threading the wires in the wire hole 230, thereby reducing the stress on the cable.

[0041] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 5 As shown, a plurality of positioning holes 2223 are provided on the rigid wall 222 of the U-shaped member 220 away from the through slot 2221. The plurality of positioning holes 2223 are arranged along the direction in which the slide rod extends. The wire clamping plate 300 is provided with positioning columns that cooperate with the positioning holes 2223. The positioning columns are inserted into the positioning holes 2223 to position the wire clamping plate 300 in the wire passing hole 230.

[0042] Since the clamping groove 310 of the clamping plate 300 is slidably matched with the sliding rod 2222, the clamping plate 300 is not limited to sliding sideways relative to the sliding rod 2222. The clamping plate 300 can slide longitudinally relative to the sliding rod 2222 so that the positioning column of the clamping plate 300 is disengaged from the positioning hole 2223, thereby adjusting the position of the clamping plate 300 in the wire hole 230. When the operator is threading the wire, the positioning column is disengaged from the positioning hole 2223, and the clamping plate 300 can be moved to the center of the wire hole 230 and then positioned by the positioning column and the positioning hole 2223. After the threading is completed, the clamping plate 300 can be moved to a position close to the edge of the wire hole 230.

[0043] In this way, due to the positioning of the clamping plate 300 in the wire hole 230, the stability of the clamped cable is improved, and the shaking of the cable during the use of the network protection safety communication isolation device is avoided to affect the use of the cable.

[0044] In one embodiment, based on the network protection security communication isolation device of the aforementioned embodiment, a guide groove is provided on the rigid wall 222 of the U-shaped part 220 away from the through groove 2221, and the guide groove is arranged along the extension direction of the sliding rod. The wire clamping plate 300 is provided with a guide column that cooperates with the guide groove, and the guide column slides in the guide groove.

[0045] Different from the above-mentioned embodiment, the present embodiment realizes the sliding and positioning of the clamping plate 300 by the cooperation of the guide groove and the guide column. Since the cable has a certain stress when plugged into the network protection safety communication isolation device, the stress acts on the clamping plate 300 so that the clamping plate 300 has a certain deflection force, and this part of the deflection force acts on the sliding rod 2222 and the guide groove so that the clamping plate 300 and the rod body of the sliding rod 2222 and the groove wall of the guide groove generate friction, and this friction can produce a certain positioning effect on the clamping plate 300, thereby playing the role of positioning the clamping plate 300.

[0046] In this way, the cooperation between the guide groove and the guide column makes the sliding of the clamping plate 300 easier, improving the operating experience of the operator. At the same time, the force of the cable on the clamping plate 300 causes a certain friction force to be generated between the clamping plate 300 and the sliding rod 2222 and the guide groove. This friction force can play a certain role in positioning the clamping plate 300, thereby improving the stability of the clamped cable and reducing or avoiding the shaking of the cable generated during the use of the network protection safety communication isolation device, which affects the use of the cable.

[0047] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 5 As shown, an operating portion 320 is provided at one end of the clamping plate 300 away from the positioning column. The operating portion 320 may be a handle or an operating lever provided on the clamping plate 300. The operating portion 320 may be provided at the upper end of the clamping plate 300 or at the side of the clamping plate 300. The operating portion 320 provided at the side of the clamping plate 300 may extend to the rear of the sliding frame 200.

[0048] Since the wire clamping plate 300 is passed through the cable, it is inconvenient for the operator to operate the wire clamping plate 300. By providing an operating part 320 on the wire clamping plate 300, the operator can operate the wire clamping plate 300 to slide through the operating part 320, thereby avoiding the influence of the cable on the wire clamping plate 300.

[0049] In this way, it is easier for the operator to slide the wire clamping plate 300 through which the wires are threaded, thereby reducing the operating difficulty for the operator.

[0050] At the same time, the operating part 320 is arranged on the side of the wire clamping plate 300 and extends to the rear of the sliding frame 200, so that the operator does not need to insert his fingers into the wire passing hole 230 to operate the wire clamping plate 300, thereby avoiding the operator's fingers being pinched by the two wire clamping plates 300 or by the wire clamping plate 300 and the wire passing hole 230, thereby improving the safety of operation.

[0051] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 4 As shown, at least one pair of hollow guide rails 120 extending along the front-to-back direction of the box body 100 are provided on the upper and lower sides of the box body 100, and the hollow part of the guide rails 120 forms a slide groove 121. The sliding frame 200 is provided with a sliding part 240 corresponding to at least one pair of guide rails 120, and the sliding part 240 is slidably fitted in the slide groove 121.

[0052] The hollow guide rails 120 disposed on the upper and lower sides of the box body 100 and the corresponding sliding parts 240 disposed on the sliding frame 200 make the sliding of the sliding frame 200 relative to the box body 100 more stable, thereby improving the stability of the cables on the sliding frame 200 when the sliding frame 200 slides and reducing the shaking of the cables.

[0053] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 6 As shown, it also includes two groups of dustproof components 400 installed on the box body 100, and the dustproof components 400 include an upper fixing plate 410, a lower fixing plate 420 and a dustproof filter 430. A number of heat dissipation holes are respectively provided on the left and right sides of the box body 100. The two upper fixing plates 410 are respectively installed above the heat dissipation holes, and the two lower fixing plates 420 are respectively installed below the heat dissipation holes. The upper fixing plate 410 is provided with a through groove 411 for the dustproof filter 430 to pass through, and the lower fixing plate 420 is provided with a positioning groove 421 for positioning the lower end of the dustproof filter 430.

[0054] Since the network protection safety communication isolation device generates heat during use, heat dissipation holes are provided on both sides of the box 100 of the network protection safety communication isolation device to help the hot air inside the box 100 to convect and exchange heat with the outside air, thereby taking away the heat inside the network protection safety communication isolation device.

[0055] A dust filter 430 is provided on the heat dissipation hole to prevent outside air from bringing in dust, water vapor, etc. when entering the network protection safety communication isolation device, thereby causing risks such as rust and short circuit to the electrical components inside the network protection safety communication isolation device.

[0056] However, the dust filtered by the dust filter 430 will accumulate and affect the air intake effect of the dust filter 430. If the dust filter 430 is not cleaned or replaced for a long time, the heat exchange effect between the inside of the box 100 and the outside will be greatly reduced, and the heat inside the network protection safety communication isolation device is difficult to dissipate to the outside, resulting in excessive temperature inside the network protection safety communication isolation device. The dustproof assembly 400 in the present invention includes an upper fixing plate 410, a lower fixing plate 420 and a dust filter 430. The dust filter 430 is detachably installed between the upper fixing plate 410 and the lower fixing plate 420, which is convenient for operators to regularly disassemble the dust filter 430 for cleaning or replacement.

[0057] Through the above-mentioned arrangement, the dust filter 430 can be detachably installed on the outside of the heat dissipation hole, thereby reducing the risk of external dust and water vapor entering the network protection safety communication isolation device. At the same time, the detachability of the dust filter 430 facilitates the operator to regularly clean and replace the dust filter 430, thereby avoiding the use of the dust filter 430 for too long, which may lead to a decrease in the heat dissipation efficiency of the network protection safety communication isolation device.

[0058] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figures 1 to 6As shown, the upper fixing plate 410 is provided with screw holes 412 for fixing the dust filter 430, and the dust filter 430 is provided with screws 431. The dust filter 430 is fixed to the upper fixing plate 410 by screws 431, so that the dust filter 430 is detachably fixedly connected to the box body 100.

[0059] Through the above-mentioned setting, the dust filter 430 is detachably fixedly connected to the box body 100, reducing or avoiding the shaking of the dust filter 430 which causes the gap between the dust filter 430 and the box body 100 to increase and affect the dustproof effect of the dustproof component 400, thereby improving the stability of the dustproof effect of the dustproof component 400.

[0060] In one embodiment, a network protection security communication isolation device based on the aforementioned embodiment, such as Figure 2 , Figure 3 , Figure 7 As shown, the box body 100 is also provided with an upper slide rail 101, a lower slide rail 102 and a slide cover 500. The upper slide rail 101 and the lower slide rail 102 are respectively located at the upper and lower sides of the plurality of wiring ports 110. The upper slide rail 101 and the lower slide rail 102 are respectively provided with a sliding groove 103. The upper and lower ends of the slide cover 500 are respectively slidably fitted in the sliding groove 103. The slide cover 500 has a closed state and an open state. In the closed state, the slide cover 500 blocks the plurality of wiring ports 110. In the open state, the sliding of the slide cover 500 reveals the plurality of wiring ports 110.

[0061] When the network protection safety communication isolation device is not in use, the risk of dust and water vapor entering the connection port 110 is reduced. When the network protection safety communication isolation device needs to be used, the sliding cover 500 can be slid to expose the connection port 110, which is convenient for operators to connect the wires. The sliding cover 500 slides away from the box 100 to avoid the sliding cover 500 being located on the side of the box 100 and occupying the space of other equipment.
