Description

Technical Field

[0001] The utility model relates to the technical field of pipeline-connected cable-blowing sealed cabins, in particular to a sealing interface device for connecting pipelines with various outer diameters. Background Art

[0002] Silicone-core pipe is a new type of composite pipe with a silicone solid lubricant on the inner wall. It offers excellent sealing performance, chemical resistance, and low construction cost. It is widely used in optical cable communication network systems on highways, railways, and other applications. HDPE silicone-core pipe, also known as silicone pipe, is a new type of composite pipe with a silicone solid lubricant on the inner wall. It is extruded and compounded simultaneously by three plastic extruders. The main raw material is high-density polyethylene, and the core layer is silicone, a solid lubricant with the lowest friction coefficient. It is widely used in optical cable communication network systems.

[0003] Silicon-core tubes are widely used as communication pipes in highway communications and operator trunk line construction. Since communication pipes come in various models and outer diameters, the outer diameter of the pipe slot of the air-blowing equipment only has one specification, and the application range of the device is small, making it inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that communication pipes have various models and outer diameters, but the outer diameter of the pipe slot of the air blowing equipment has only one specification model, thereby the application range of the device is small and the use is inconvenient. A sealing interface device for connecting pipes of various outer diameters is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sealing interface for connecting pipes of various outer diameters, comprising two mounting blocks, the two mounting blocks being symmetrically arranged, each having an air delivery channel formed on one side thereof adjacent to the other, a mold being clamped in place within the air delivery channel, and a fixing assembly for fixing the mold being disposed between the air delivery channel and the mold;

[0007] An annular groove is provided on the inner wall of the mold, and two second rectangular grooves are symmetrically arranged at one end of the mold, the second rectangular grooves are connected to the annular groove, and a clamping assembly for clamping the silicon core tube is provided inside the annular groove;

[0008] One end of the mold is rotatably connected to a rotating ring, and an outer wall of the rotating ring is provided with a limiting component for limiting the rotating ring.

[0009] In one possible design, the fixing assembly includes an inner limit groove and an outer limit groove opened inside the air delivery channel, and the outer wall of the mold is provided with an outer limit block and an inner limit block, the outer limit block is engaged with the outer limit groove, and the inner limit block is engaged with the inner limit groove.

[0010] In one possible design, the clamping assembly includes a clamping block arranged inside the annular groove, one side of the clamping block is fixedly connected to a rectangular block, the rectangular block is slidably connected to one side of the second rectangular groove, and the same first spring is fixedly connected between one side of the rectangular block and the inner wall of one side of the second rectangular groove.

[0011] In one possible design, the limiting assembly includes a positioning groove opened at the top of the rotating ring, a positioning rod slides through the interior of the positioning groove, a pressing block is fixedly connected to the top of the positioning rod, and a second spring is fixedly connected between the bottom of the pressing block and the top of the rotating ring.

[0012] In a possible design, two arc-shaped blocks are fixedly connected to the interior of the rotating ring, and the arc-shaped blocks are used in conjunction with the rectangular blocks.

[0013] In one possible design, an arc groove is opened at one end of the mold, and two first rectangular grooves are symmetrically arranged at one end of the mold. The two first rectangular grooves are respectively located at both ends of the arc groove and are connected to the arc groove. The arc groove and the first rectangular groove are both used in conjunction with the pressing block.

[0014] In a possible design, a first installation cavity and a second installation cavity are defined inside the mold, and a first sealing ring and a second sealing ring are embedded in the first installation cavity and the second installation cavity, respectively.

[0015] In a possible design, a threaded groove is provided at one end of the mounting block, and a plurality of threaded holes are provided inside the mounting block.

[0016] In the present application, when inserting the silicon core tube, the silicon core tube can be inserted from one end of the mold. At this time, the provision of the first sealing ring and the second sealing ring can improve the sealing between the silicon core tube and the mold. After insertion, the pressing block can be pressed, and the pressing block moves down from the inside of the first rectangular groove on one side to the inside of the arc groove. The positioning rod enters the inside of the positioning groove, and the second spring is squeezed. At this time, the braking state of the rotating ring can be released;

[0017] At this time, the rotating ring can be rotated, and the pressing block moves from the inside of the arc groove to the inside of another first rectangular groove. At this time, the rotating ring drives the two arc blocks to rotate, and the arc blocks gradually push the rectangular blocks to move laterally. The rectangular blocks squeeze the first spring and drive the clamping blocks to move laterally. The two clamping blocks approach each other and can clamp the silicon core tube to prevent gas leakage.

[0018] The two mounting blocks are installed on the air blowing equipment through threaded grooves. When the outer diameter of the silicon core tube changes, the two mounting blocks can be separated and the mold can be taken out. After the removal is completed, the mold with another inner diameter can be replaced through the clamping connection between the air delivery channel and the mold, the clamping of the inner limit block and the inner limit groove, and the clamping of the outer limit block and the outer limit groove. It can then be suitable for silicon core tubes with different outer diameters, thereby enhancing the scope of use of the device.

[0022] In the utility model, the silicon core tube is inserted from one end of the mold. At this time, the setting of the first sealing ring and the second sealing ring can improve the sealing between the silicon core tube and the mold. By rotating the rotating ring, the two clamping blocks are close to each other and can clamp the silicon core tube to prevent gas leakage. When the outer diameter of the silicon core tube changes, the two mounting blocks can be separated, the mold can be taken out, and a mold with another inner diameter can be replaced, so that it can be suitable for silicon core tubes with different outer diameters, thereby improving the use range of the device.
