Description

Technical Field

[0001] The utility model relates to the field of cable duct plugging, in particular to a plugging device for a 5G communication cable duct. Background Technique

[0002] A 5G communication cable is a communication cable designed specifically for 5G networks, usually having high-performance transmission characteristics to support the requirements of high-speed data transmission and low latency. During the process of building a communication transmission channel, 5G communication cables are generally laid in a sealed manner in cable ducts. Among them, the device for realizing the sealed laying of 5G communication cables is a plugging device for cable ducts. This plugging device is applied inside the cable duct and is used to plug the cross-section of the cable duct hole, that is, by expanding inward and outward, the gaps between the inner wall of the cable duct and the outer wall of the plugging device and between the inner wall of the plugging device and the outer wall of the cable are plugged, so as to realize the plugging of the cross-section of the cable duct hole. The so-called inward and outward expansion refers to the deformation of the deformable tube after being stressed to fill the gap.

[0003] In the prior art, in addition to the above-mentioned deformable tube, a plugging tube and a pressure application tube are also provided for the cable duct hole plugging device. The deformable tube and the pressure application tube are both connected to the plugging tube by means of threaded connection. Pressure is applied to the deformable tube by the advancement of the pressure application tube on the plugging tube, so that the deformable tube deforms. Among them, the plugging tube, the pressure application tube, and the deformable tube are all assembled by the same two parts, and the assembly parts of the plugging tube, the deformable tube, and the pressure application tube are all non-sealed parts. During the long-term use of the plugging device, the accumulated liquid may seep into the plugging device through the assembly parts and then enter the duct through the gaps between the cables and between the cable and the deformable tube. At present, corresponding problems have indeed been found in the corresponding products of our company, especially in some non-excellent workpieces; in addition, the cable duct plugging device of the prior art only contacts and seals with the cable duct through the deformed deformable tube, and the friction between the two is small. When sorting and maintaining the cables, the cables may move, resulting in the separation of the two and the problem of seal failure. Therefore, a plugging device for cable ducts is proposed.

The same reference numerals in the drawings denote elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0022] In addition, for better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0023] Embodiment 1, please refer to Figures 1 to 4 In the shown structure, in the embodiment of the present utility model, a plugging device for a 5G communication cable duct includes a plugging pipe 1, an outer sealing rubber ring 2, a gasket 3, a first propulsion cylinder 4, an inner sealing rubber ring 7, and a second propulsion cylinder 6, and further includes a fixing member 5 disposed on the side surface of the second propulsion cylinder 6 and a seepage-proof member 8 disposed on the inner wall of the second propulsion cylinder 6;

[0024] The fixed mounting member 5 includes a first mounting disc 51, a second mounting disc 52, and a mounting cylinder 54 provided on the first mounting disc 51. A turntable 53 is rotatably mounted on the outer wall of the mounting cylinder 54, and a fixed block 55 is also fixedly mounted on the outer wall of the mounting cylinder 54. The fixed mounting member 5 further includes a winding column 56 which penetrates through the fixed block 55, and the fixed block 55 is rotatably connected to the winding column 56. One end of the winding column 56 is fixedly connected to the side wall of the second mounting disc 52. A rotating piece 58 is rotatably connected to the winding column 56, and a rotating bar 511 is rotatably connected to the rotating piece 58. One end of the rotating bar 511 is rotatably connected to the turntable 53. A stop piece 510 is provided on the rotating bar 511. The turntable 53 is used to drive one end of the rotating bar 511 to move outward away from the turntable 53 so as to drive the stop piece 510 to move outward away from the first mounting disc 51.

[0025] In this embodiment, by rotating and moving the first pushing cylinder 4 and the second pushing cylinder 6 on the plugging pipe 1 to apply pressure to the outer sealing ring 2 and the inner sealing ring 7 respectively, the outer sealing ring 2 and the inner sealing ring 7 are deformed under force. Among them, the outer sealing ring 2 deforms outward, so that the gap between the outer wall of the plugging pipe 1 and the cable duct is filled. The inner sealing ring 7 deforms inward, thereby tightly wrapping the cable passing through the plugging pipe 1 and plugging the gap between the cable and the inner wall of the plugging pipe 1. Threads are provided on the plugging pipe 1. The outer sealing ring 2, the gasket 3, the first pushing cylinder 4, and the second pushing cylinder 6 are sequentially sleeved on the outer wall of the plugging pipe 1 in a threaded connection manner. The outer wall of the inner sealing ring 7 is threadedly connected to the inner wall of the plugging pipe 1. It should be noted that the plugging pipe 1, the outer sealing ring 2, the gasket 3, the first pushing cylinder 4, the inner sealing ring 7, and the second pushing cylinder 6 are all assembled by the same two parts. Regarding the structures and functions of the above components, reference can be made to the Chinese patent with the patent number CN110416960B and the patent name "An underground cable duct plugging device". In this patent, the connection methods, structures, and functions of the above plugging pipe 1, outer sealing ring 2, gasket 3, first pushing cylinder 4, inner sealing ring 7, and second pushing cylinder 6 are disclosed and will not be elaborated here. Additionally, it should be noted that reference Figure 2 , a retaining ring 10 is provided inside the plugging pipe 1, which is used to cooperate with the second pushing cylinder 6 to extrude the inner sealing ring 7. Taking the second pushing cylinder 6 as a reference, the side surface of the outer sealing ring 2 close to the reference and the side surface of the retaining ring 10 away from the reference are located in the same vertical plane. According to Figure 2It can be seen that since the outer sealing rubber ring 2 seals the gap between the plugging device and the cable duct, when the outer sealing rubber ring 2 is in a normal state, the accumulated liquid will not seep into the cable duct from the contact part between the outer sealing rubber ring 2 and the cable duct. However, the combination part of each component (including the second propulsion cylinder 6) between the second propulsion cylinder 6 and the outer sealing rubber ring 2 (because each component is composed of two parts) may become a water seepage part. Since the outer sealing rubber ring 2 needs to be extruded by the second propulsion cylinder 6, the outer sealing rubber ring 2 is not provided inside the second propulsion cylinder 6. Then, after ensuring that the side of the outer sealing rubber ring 2 close to the reference and the side of the retaining ring 10 away from the reference are in the same vertical plane, the possible water seepage parts inside each component of the cable plugging device can only appear on the second propulsion cylinder 6. By providing the anti-seepage part 8, it can prevent the liquid from seeping into the cable channel through the second propulsion cylinder 6.

[0026] Further, the second mounting disc 52 is threadedly connected to the side wall of the second propulsion cylinder 6, and an air duct 9 is provided inside the second mounting disc 52.

[0027] In this embodiment, both parts of the second propulsion cylinder 6 are provided with thread grooves. After the two parts of the second propulsion cylinder 6 are combined, the thread grooves are combined together to form a threaded hole (not shown in the figure). An installation ring (not shown in the figure) is provided on the side surface of the second mounting disc 52, and threads opposite to the threaded hole are provided on the installation ring. The second mounting disc 52 is connected to the second propulsion cylinder 6 by a threaded connection method.

[0028] Further, the number of the fixing blocks 55, the winding columns 56, the rotating pieces 58, and the rotating bars 511 is several, and several fixing blocks 55 are arranged in an array on the outer wall of the mounting cylinder 54.

[0029] In this embodiment, the number of the fixing blocks 55, the winding columns 56, the rotating pieces 58, and the rotating bars 511 is equal. Each winding column 56 penetrates through a fixing block 55, a rotating piece 58 is rotatably connected to a winding column 56, and each rotating bar 511 is rotatably connected to a rotating piece 58.

[0030] Further, the fixing member 5 further includes a first rotating pin 59 and a second rotating pin 512. One end of the rotating bar 511 is rotatably connected to the fixing block 55 through the first rotating pin 59, and the other end of the rotating bar 511 is rotatably connected to the turntable 53 through the second rotating pin 59.

[0031] In this embodiment, when the turntable 53 rotates, a thrust will be applied to the rotating bar 511, causing the rotating piece 58 to be subjected to the thrust. Since both the rotating piece 58 and the rotating bar 511 tend to rotate when subjected to the thrust and their rotation is not restricted, when the turntable 53 rotates, it will drive the rotating piece 58 to rotate around the spiral column 56. At this time, one end of the rotating bar 511 rotates relative to the rotating piece 58, and the other end of the rotating bar 511 rotates relative to the turntable 53. This enables the rotating bar 511 to rotate around the circle of the turntable, and the end of the rotating piece 58 connected to the rotating bar 511 will also rotate around the second rotating pin 512. This enables the rotating bar 511 to rotate outwards from the turntable 53, causing the baffle 510 to rotate outwards from the first mounting plate 51.

[0032] Further, a push handle 57 is provided on the outer wall of the turntable 53. A bolt is threadedly connected to the push handle 57. A positioning ring 513 is provided along the outer circumference of the first mounting plate 51, and a threaded hole opposite to the bolt is provided on the positioning ring 513.

[0033] In this embodiment, there are several threaded holes. When the turntable 53 rotates to the required position, the bolt is turned to threadedly connect it with the threaded hole on the positioning ring 513, fixing the turntable 53 at this position.

[0034] Further, the anti-seepage member 8 includes a protection plate 81. A fixing strip 82 is provided on the side wall of the protection plate 51. An airbag strip 83 is provided inside the fixing strip 82. An inflation hole is provided on one side of the airbag strip 83, and the inflation hole communicates with the air duct 9.

[0035] In this embodiment, an installation groove is provided inside the fixing strip 82. The airbag strip 83 is bolted to the installation groove. The number of anti-seepage members 8 is two, and the two anti-seepage members 8 are respectively arranged in two parts of the second propulsion cylinder 6. After the two parts of the second propulsion cylinder 6 are combined together, the two anti-seepage members 8 are combined with each other to surround the cable. A ventilation hole opposite to the inflation hole and the air duct 9 is provided in the protection plate 81. The airbag strip 83 is inflated by external inflation, and after the inflation is completed, the air inlet of the air duct 9 is sealed.

[0036] Further, through holes are provided in the first mounting plate 51, the second mounting plate 52, and the mounting cylinder 54 for the cable to pass through the above components.

[0037] The specific operation method of the plugging device for the 5G communication cable pipeline is as follows: Combine the plugging pipe 1, the outer sealing rubber ring 2, the gasket 3, the first propulsion cylinder 4, the inner sealing rubber ring 7 and the second propulsion cylinder 6. It should be noted that before combining the above components, the cable needs to be placed inside first. After combination, thread-connect the second mounting plate 52 with the second propulsion cylinder 6. At this time, the cable is plugged inside the plugging device, and the plugging device is plugged inside the cable pipeline. Inflate the inside of the air passage 9 through an external air inflation device, so that the two airbag strips 83 are deformed. The deformed airbag strips 83 will plug the side wall of the inner sealing rubber ring 7. After inflation, plug the air passage 9. Then, rotate the push handle 57 to make the turntable 53 rotate. The rotating strip 511 rotates accordingly and drives the retaining piece 510 to move outward from the first mounting plate 51. When the retaining piece 510 abuts against the inner wall of the cable pipeline, stop rotating the push handle 57 and fix the push handle 57 at this position by means of bolt connection.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0039] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
