Description

Technical Field

[0001] This utility model relates to the field of silicon core tube technology, and in particular to a composite polypropylene silicon core tube. Background Technology

[0002] Composite polypropylene silicon core pipe is a new type of pipe material that combines polypropylene material with silicon core layer structure, and is widely used in communications, municipal engineering, transportation and other fields.

[0003] When laying and connecting composite polypropylene silicone core pipes, hot-melt butt welding is mostly used. However, using hot-melt equipment is relatively troublesome and the construction efficiency is low. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a composite polypropylene silicon core pipe to solve the problem of low construction efficiency when laying and connecting composite polypropylene silicon core pipes in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A composite polypropylene silicone core tube includes a tube body and a connecting assembly. The connecting assembly includes a connecting pipe and locking heads disposed at both ends of the connecting pipe. A connecting ring is detachably installed inside the connecting pipe. When two tube bodies are connected, the two locking heads lock the two tube bodies respectively. One end of the connecting ring abuts against the end of the tube body, and the other end abuts against the end of the adjacent tube body.

[0007] By setting up the above structure, the ends of the two pipes to be connected are pressed against the connecting ring, and then the pipes are locked with the locking head to achieve the connection of the two pipes. The operation is simple, convenient and quick.

[0008] Furthermore, the connecting pipe has multiple fixing blind holes, the connecting ring has multiple first threaded holes, a first fixing bolt is inserted into the fixing blind hole, and the end of the first fixing bolt is threaded into the first threaded hole.

[0009] By setting up the above structure, when it is necessary to dismantle the two connected pipes, first release the locking head from the pipe, then release the connection between the connecting ring and the connecting pipe by rotating the first fixing bolt, and then slide the pipe to disconnect the connection between the two pipes. There is no need to move the pipe axially, which improves the convenience of subsequent pipeline maintenance.

[0010] Furthermore, sealing grooves are provided on both sides of the connecting ring, and sealing rings are provided in the sealing grooves.

[0011] By setting up the above structure, the sealing performance of the pipe connection is effectively improved.

[0012] Furthermore, the locking head includes a mounting ring and a locking ring. The mounting ring is fixedly connected to the connecting pipe. The mounting ring has multiple slots, and locking blocks are slidably disposed in each of the multiple slots. A guide slope is provided at one end of the locking block near the locking ring. The mounting ring has a locking section. When the locking ring moves toward the locking section, the locking ring pushes the multiple locking blocks to slide toward the axis of the pipe body.

[0013] By setting up the above structure, the locking ring can be moved to the locking section to lock the pipe body, thus achieving the locking head to lock the pipe body.

[0014] Furthermore, the mounting ring is provided with an external thread section, and the locking ring is provided with a first ring body on the side near the mounting ring. The first ring body is provided with an internal thread section. When the internal thread section is threaded onto the external thread section, the locking ring and the mounting ring are relatively fixed in position.

[0015] By setting up the above structure, the position of the locking ring can be fixed while the locking ring moves through the internal thread section and the external thread section, thus preventing the locking ring from loosening.

[0016] Furthermore, a second ring is rotatably connected to the first ring. When the locking ring moves toward the locking section, the second ring pushes multiple locking blocks to slide toward the axis of the tube.

[0017] By setting the above structure, the second ring body and the locking ring can rotate relative to each other, thereby solving the problem that after the second ring body is connected to the locking block, the locking block will generate a large rotational resistance on the second ring body, which will affect the rotation of the locking ring.

[0018] Furthermore, the mounting ring has multiple fixing holes, the connecting pipe has multiple second threaded holes, the locking block has a through groove, a limiting rod is inserted into the fixing hole, and one end of the limiting rod passes through the through groove and is threaded into the second threaded hole.

[0019] By setting the above structure, a sliding connection between the locking block and the mounting ring is achieved.

[0020] The beneficial effects of this utility model are:

[0021] 1. By setting a locking head and a connecting ring, the ends of the two pipes to be connected are pressed against the connecting ring, and then the locking head is used to lock the pipes to achieve the connection of the two pipes. The operation is simple, convenient and quick.

[0022] 2. By setting an installation ring and a locking ring, moving the locking ring to the locking section will allow the locking block to lock the pipe body, thus achieving the locking of the locking head onto the pipe body.

[0023] 3. By setting a first ring body, a second ring body, an internal thread section, and an external thread section, the position of the locking ring can be fixed while the locking ring moves, preventing the locking ring from loosening. In addition, the second ring body and the locking ring can rotate relative to each other, preventing the locking block from generating large rotational resistance on the second ring body after the second ring body comes into contact with the locking block, which would affect the rotation of the locking ring.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0035] like Figures 1-4 As shown, this utility model discloses a composite polypropylene silicon core tube, comprising a tube body 1 and a connecting assembly. The connecting assembly includes a connecting tube 2 and locking heads 3 disposed at both ends of the connecting tube 2. A connecting ring 21 is detachably installed inside the connecting tube 2. When two tube bodies 1 are connected, the two locking heads 3 respectively lock the two tube bodies 1. One end of the connecting ring 21 abuts against the end of the tube body 1, and the other end abuts against the end of the adjacent tube body 1. By pressing the ends of the two tube bodies 1 to be connected against the connecting ring 21 and then locking the tube bodies 1 with the locking heads 3, the connection of the two tube bodies 1 can be achieved. The operation is simple, convenient, and quick.

[0036] In this embodiment, the connecting pipe 2 has multiple fixing blind holes 22, and the connecting ring 21 has multiple first threaded holes 211. In this embodiment, the number of fixing blind holes 22 and first threaded holes 211 is set to six. In practice, the number of fixing blind holes 22 and first threaded holes 211 can be increased or decreased according to needs. A first fixing bolt 23 is inserted into the fixing blind hole 22. The first fixing bolt 23 is an internal hexagonal bolt. The end of the first fixing bolt 23 is threaded into the first threaded hole 211. In some other embodiments, the connecting ring 21 can also be fixed from the inside by bolts. In this embodiment, by opening fixing blind holes 22 on the connecting pipe 2, when it is necessary to disassemble the two connected pipe bodies 1, first release the locking head 3 from the pipe body 1, then release the connection between the connecting ring 21 and the connecting pipe 2 by rotating the first fixing bolt 23, and then slide the pipe body 1 to disconnect the connection between the two pipe bodies 1 without axial movement of the pipe body 1, thus improving the convenience of subsequent pipeline maintenance.

[0037] In this embodiment, sealing grooves are provided on both sides of the connecting ring 21, and sealing rings 212 are provided in the sealing grooves, which effectively improves the sealing performance of the pipe body 1 connection.

[0038] In this embodiment, the locking head 3 includes a mounting ring 31 and a locking ring 32. The mounting ring 31 is fixedly connected to the connecting pipe 2. In this embodiment, the mounting ring 31 and the connecting ring 21 are integrally formed. The mounting ring 31 has multiple slots 311, which are located on the side near the connecting pipe 2. Locking blocks 4 are slidably disposed in each of the multiple slots 311. The number of locking blocks 4 is set to six. The locking ring 32 is slidably mounted on the pipe body 1. The end of the locking block 4 near the locking ring 32 is provided with a guide slope 41. The mounting ring 31 is provided with a locking section 312. When the locking ring 32 moves towards the locking section 312, the locking ring 32 pushes the multiple locking blocks 4 to slide towards the axis of the pipe body 1. Moving the locking ring 32 to the locking section 312 can lock the locking blocks 4 into the pipe body 1, thereby locking the pipe body 1 with the locking head 3. In some other embodiments, an annular locking block 4 with a notch can also be used, and the annular locking block 4 can be locked to the tube body 1 by the compression of the annular locking block 4 by the locking ring 32.

[0039] In this embodiment, the mounting ring 31 is provided with an external thread section 313, and the locking ring 32 is provided with a first ring body 321 on the side near the mounting ring 31. The first ring body 321 is provided with an internal thread section 322. When the internal thread section 322 is threaded onto the external thread section 313, the locking ring 32 and the mounting ring 31 are relatively fixed in position. While the locking ring 32 moves, its position can be fixed to prevent it from loosening.

[0040] In this embodiment, a second ring body 323 is rotatably connected to the first ring body 321. When the locking ring 32 moves toward the locking section 312, the second ring body 323 pushes multiple locking blocks 4 to slide toward the axis of the tube body 1. This allows the second ring body 323 and the locking ring 32 to rotate relative to each other, thereby solving the problem that after the second ring body 323 is in contact with the locking blocks 4, the locking blocks 4 will generate a large rotational resistance on the second ring body 323, affecting the rotation of the locking ring 32.

[0041] In this embodiment, the mounting ring 31 has multiple fixing holes 314, the connecting pipe 2 has multiple second threaded holes 24, and the locking block 4 has a through groove 42. Two fixing holes 314 and two second threaded holes 24 form a group, and both fixing holes 314 and two second threaded holes 24 in a group communicate with the through groove 42. A limiting rod 43 is inserted into the fixing hole 314, and one end of the limiting rod 43 passes through the through groove 42 and is threaded into the second threaded hole 24, thereby realizing the sliding connection between the locking block 4 and the mounting ring 31. In some other embodiments, a limiting block can also be provided on the locking block 4, and a limiting groove can be provided on the mounting ring 31. The limiting block is slidably locked in the limiting groove, thereby realizing the sliding connection between the locking block 4 and the mounting ring 31.

[0042] The method of using this utility model is as follows:

[0043] When the two pipes 11 are connected:

[0044] First, place the connecting component between the two pipes 1 that need to be connected;

[0045] Then, the connecting tube 2 is fitted onto one end of a tube body 1 until the end of the tube body 1 abuts against the connecting ring 21. Then, by rotating the corresponding locking ring 32, the corresponding locking head 3 locks the tube body 1.

[0046] Then, insert one end of another tube 1 into the connecting tube 2 until the end of the tube 1 abuts against the connecting ring 21, and then lock the tube 1 by rotating the corresponding locking ring 32.

[0047] During the process of rotating the locking ring 32 to lock the pipe body 1 with the locking head 3, after the internal thread section 322 of the first ring body 321 is threadedly connected to the external thread section 313 of the mounting ring 31, the rotation of the locking ring 32 drives the first ring body 321 to rotate, causing the locking ring 32 to drive the first ring body 321 and the second ring body 323 to move closer to the mounting ring 31. When the second ring body 323 moves closer to the mounting ring 31, the second ring body 323 pushes multiple locking blocks 4 to slide closer to the axis of the pipe body 1 through the guide inclined surface 41, so that the locking blocks 4 lock with the outer wall of the pipe body 1, thereby realizing the locking of the pipe body 1 by the locking head 3.

[0048] When it is necessary to disassemble the two connected pipes 1, first release the locking head 3 from the pipe 1, then release the connection between the connecting ring 21 and the connecting pipe 2 by rotating the first fixing bolt 23, and then slide the pipe 1 to disconnect the connection between the two pipes 1.
