Description

Technical Field

[0001] The utility model relates to the field of pipeline plugs, in particular to a pipeline plug which is easy to disassemble. Background Art

[0002] To prevent dust, gravel and other debris from entering the wire pipe and affecting the normal operation of the cable line, a plug is usually installed at the end of the pipe to protect the cables inside the pipe. There are many types of pipe plugs, including waterproof rubber rings and sealing rings, which can effectively prevent rainwater, snow water, water vapor and other moisture from entering the wire pipe and protect the safe operation of the cable line. Inflatable pipe plugs can prevent insects and rodents from entering the cable pipe.

[0003] Different pipe plugs have different installation methods. Although the inflatable type is easy to install and disassemble, the inflation cannot make the plug in a safe and sealed state, which will result in poor waterproof effect. Traditional sealing rings need to be used with adhesives during installation. Although the sealing is good enough, it is more difficult to disassemble. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a pipe plug that is easy to disassemble includes two semi-annular sealing tubes 1, and semi-annular sealing plates 2 are fixedly installed at the ends of the sealing tubes 1. The sealing plates 2 and the sealing tubes 1 are made of an integrally formed plastic material, and the two form a complete circular tube and an annular plate. The outer diameter of the sealing plate 2 is larger than the diameter of the pipe. When installing, it is ensured that the sealing plate 2 can cover the position of the pipe opening. A rotating rod 3 is movably installed on the outer surface of the sealing tube 1. In this embodiment, the number of rotating rods 3 on the surface of each sealing tube 1 is two, and a semi-annular extrusion plate 4 is movably installed on the end of the rotating rod 3. The two ends of the rotating rod 3 are installed and connected to the extrusion plate 4 and the sealing tube 1 through a torsion spring 5. The initial state of the torsion spring 5 is to make the rotating rod 3 in a completely vertical state.

[0021] When installing it, the extrusion plate 4 is close to the surface of the sealing tube 1. At this time, the torsion spring 5 is in a compressed state and is directly inserted into the interior of the pipe. At this time, both hands are released. Due to the resilience of the torsion spring 5, the extrusion plate 4 is close to the interior of the pipe. The friction between the extrusion plate 4 and the inner wall of the pipe makes the extrusion plate 4 in a stable state. At this time, the resilience of the other torsion spring 5 will pull the sealing tube 1 to continue to move toward the interior of the pipe until it is in a completely stable state and the pulling trend is maintained. At this time, the sealing plate 2 can be tightly attached to the position of the pipe mouth to ensure good sealing performance. When disassembling, you only need to pull the sealing plate 2 away from the pipe. The operation is simple, convenient and fast.

[0022] The surface of the sealing tube 1 and the inner surface of the extrusion plate 4 are fixedly mounted with mounting seats 6, and there are four mounting seats 6. Round shafts 7 are fixedly mounted at both ends of the rotating rod 3. A round groove 8 is provided inside the mounting seats 6. The torsion spring 5 is sleeved on the surface of the round shaft 7, one end of the torsion spring 5 is fixed inside the round groove 8, and the other end of the torsion spring 5 is fixed to the surface of the rotating rod 3.

[0023] An annular rubber pad 9 is installed on the surface of the extrusion plate 4. Since the extrusion plate 4 needs to rub against the inner wall of the pipe for a long time, long-term use may cause wear on the surface of the extrusion plate 4. At this time, the rubber pad 9 is used to protect the extrusion plate 4 and increase the friction between the extrusion plate 4 and the inner wall of the pipe.

[0024] A through groove 10 is provided on the surface of the extrusion plate 4. In the present embodiment, there are three through grooves 10. A rubber rod 11 is fixedly installed on the inner side of the rubber pad 9. The rubber rod 11 is fully matched with the through groove 10. The rubber rod 11 is inserted into the inside of the through groove 10. A protrusion 12 is fixedly installed on the end of the rubber rod 11. The protrusion 12 abuts against the inner side of the extrusion plate 4. When the rubber pad 9 needs to be replaced, it only needs to be pulled out from the inside of the through groove 10, and then a new rubber pad 9 is replaced. The installation method is simple and convenient.

[0025] The rubber rod 11, rubber pad 9 and protrusion 12 are an integrally formed structure, all of which are made of rubber. The protrusion 12 is set to be cylindrical, and its lower end is set to be round head shape, and its diameter is larger than the diameter of the through groove 10. Due to the shape of the protrusion 12, it can be stuck into the inside of the through groove 10 during installation, but it is very difficult to pull it out in the opposite direction, so the stability of the rubber pad 9 can be guaranteed. When it needs to be replaced, since the rubber pad 9 is damaged during use, the protrusion 12 can be cut off, which is convenient for replacing the rubber pad 9.

[0026] The inner side of the sealing tube 1 and the back side of the sealing plate 2 are all fixedly mounted with rubber auxiliary plates 13 to increase the sealing performance between the sealing tube 1 and the pipeline.

[0027] It should be noted that the utility model is a pipe plug that is easy to disassemble. When in use, the extrusion plate 4 is close to the surface of the sealing tube 1. At this time, the torsion spring 5 is in a compressed state and is directly inserted into the interior of the pipe. At this time, both hands are released. Due to the resilience of the torsion spring 5, the extrusion plate 4 is close to the interior of the pipe. The friction between the extrusion plate 4 and the inner wall of the pipe makes the extrusion plate 4 in a stable state. At this time, the resilience of the other torsion spring 5 will pull the sealing tube 1 to continue to move toward the interior of the pipe until it is in a completely stable state and the pulling trend is maintained. At this time, the sealing plate 2 can be tightly attached to the position of the pipe mouth to ensure good sealing performance. When the rubber pad 9 needs to be replaced, the protrusion 12 is cut off, the rubber rod 11 is pulled out from the inside of the through groove 10, a new rubber pad 9 is replaced, and the protrusion 12 is passed through the through groove 10.
