Abstract
Description
Technical Field
[0001] The utility model relates to the field of cable installation accessories, in particular to a cable conduit plugger with adjustable diameter. Background Art
[0002] Where cable trenches enter buildings (including control rooms and switch rooms), they are equipped with blocking walls to prevent the spread of fire and smoke from cable fires. They also prevent water, small animals, and other intruders from damaging electrical equipment or the work environment. While these blocking walls generally prevent fire, they struggle to prevent water intrusion. Traditional blocking methods, such as inflatable pump bladders or other methods, lack effective sealing. Furthermore, each blocking structure cannot adapt to different diameters or be easily replaced for installation. Therefore, we propose a diameter-adjustable cable duct plug. Utility Model Content
[0003] The main purpose of the utility model is to provide a cable conduit plug with adjustable diameter, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A diameter-adjustable cable conduit plugger comprises a sealing plate structure, a surface of which is fixedly provided with a fixing screw ring, an inner sealing structure is screw-fixedly provided in the fixing screw ring, and a port plug is screw-fixedly provided at one port of the inner sealing structure.
[0006] Furthermore, the sealing plate structure includes a panel, an outer rubber ring, an inner rubber ring and an expansion screw hole. The outer rubber ring is fixedly installed on the rear surface of the panel near the edge, and the inner rubber ring is fixedly installed on the rear surface of the panel on the inner side of the outer rubber ring. The surface of the panel is located between the outer rubber ring and the inner rubber ring and is provided with an expansion screw hole.
[0007] Furthermore, the outer rubber ring and the inner rubber ring have the same thickness.
[0008] Furthermore, the internal sealing structure includes an embedded tube, a packaging ring, a hexagonal knob, a docking screw ring, a sealing gasket, a guide bucket, a tightening silicone tube sleeve and a silicone elastic ring. The outer surface of the embedded tube is fixedly sleeved with a packaging ring, the surface of the embedded tube is fixedly sleeved with a hexagonal knob near one end, the surface of the embedded tube is fixedly sleeved with a docking screw ring on one side of the hexagonal knob, the outer side of the docking screw ring is sleeved with a sealing gasket, the inside of the embedded tube is fixedly sleeved with guide buckets near the two ports, the small ports of the guide buckets are fixedly connected with tightening silicone tube sleeves, and the surface of the tightening silicone tube sleeve is reinforced with a silicone elastic ring.
[0009] Furthermore, there are two packaging rings in total, and the docking screw ring is matched with the fixing screw ring.
[0010] Furthermore, the inner sealing structure is fixedly installed with the panel by screwing the docking screw ring into the fixing screw ring, a thread is provided on the inner side of one end of the embedded tube, and the port plug is sealed with a port of the embedded tube through the thread.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the utility model, the cable pipe plugger is provided with a tightening silicone sleeve that can shrink according to the thickness of the pipe and fit tightly against the pipe to achieve a sealing effect. If the pipeline is too thin, the inner sealing structure can be replaced with a thinner tightening silicone sleeve. The installation operation is simple and convenient, and the overall sealing and waterproof performance is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example 1:
[0019] like Figure 1-4 As shown, a diameter-adjustable cable conduit plug includes a sealing plate structure 1, a fixing screw ring 2 is fixedly installed through the surface of the sealing plate structure 1, an inner sealing structure 3 is screwed and fixedly installed in the fixing screw ring 2, and a port plug 4 is screwed and fixed to one end of the inner sealing structure 3, wherein the port plug 4 is used to block those preset ports to prevent water from entering through the preset ports;
[0020] The sealing plate structure 1 includes a panel 101, an outer rubber ring 102, an inner rubber ring 103 and an expansion screw hole 104. The outer rubber ring 102 is fixedly installed on the rear surface of the panel 101 near the edge, and the inner rubber ring 103 is fixedly installed on the rear surface of the panel 101 on the inner side of the outer rubber ring 102. The surface of the panel 101 is located between the outer rubber ring 102 and the inner rubber ring 103 and is penetrated by an expansion screw hole 104. When the expansion screw passes through the expansion screw hole 104, a sealing gasket is sleeved on the surface of the screw to seal the port gap of the expansion screw hole 104; the outer rubber ring 102 and the inner rubber ring 103 have the same thickness; the internal sealing structure 3 includes an embedded tube 301, a packaging ring 302, a hexagonal knob 303, a docking screw ring 304, a sealing gasket 305, a guide bucket 306, a tightening silicone tube sleeve 307 and a silicone elastic ring 308. The outer surface of the embedded tube 301 is fixedly sleeved with a sealing gasket The cam 308 is a kind of sealing member that is fixed on the cam 309, and the cam 309 of the cam 309 is a kind of sealing member that is fixed on the cam 309.
[0021] It should be noted that the present invention is a cable conduit plug with adjustable diameter. During installation, align the port of the fixing screw ring 2 with the inlet port of the cable conduit, then drill a hole in the inlet wall according to the position of the expansion screw hole 104, and then pass the expansion screw through the expansion screw hole 104 to fix the panel 101 on the wall. At this time, when the screw presses the panel 101, the outer rubber ring 102 and the inner rubber ring 103 can be pressed against the wall to form two seals. Then the cable passes through the two tightening silicone sleeves 307 embedded in the tube 301, and can be supported when passing through. The opener will stretch out the tightening silicone sleeve 307 to facilitate the insertion of the cable. After insertion, it will be loosened and the tightening silicone sleeve 307 will be tightly attached to the cable. At this time, the staff can tighten one of the extended tightening silicone sleeves 307 to reinforce the cable by tightening the cable tie, and then embed the embedding tube 301 into the cable pipe. At this time, the two packaging rings 302 will be tightly attached to the cable pipe to form the third and fourth sealing structures toward the inner wall of the cable pipe. Then the docking screw ring 304 will be screwed on the port of the fixed screw ring 2 and sealed by the sealing gasket 305. In this way, the installation of a cable can be completed.
