Description

Technical Field

[0001] The utility model relates to the field of cable silicon core pipes, and specifically relates to a cable silicon core pipe which is convenient for butt joint. Background Technique

[0002] The silicon core pipe is a new type of composite pipe with a silica gel solid lubricant on the inner wall, having good sealing performance, chemical corrosion resistance, and low project cost. It is widely used in the optical cable communication network systems such as highways and railways. The silicon core pipe is a new type of composite pipe with a silica gel solid lubricant on the inner wall, having good sealing performance, chemical corrosion resistance, and low project cost. It is widely used in the optical cable communication network systems such as highways and railways. Its main raw material is high-density polyethylene, and the core layer is silica gel with the lowest coefficient of friction as the solid lubricant. When most silicon core pipes are installed, new silicon core pipes often need to be butt-jointed.

[0003] For the existing cable silicon core pipes that are convenient for butt joint, the butt joint of the silicon core pipes usually adopts the method of hot melt butt joint or installing an external joint. When using the hot melt butt joint method, a hot melt machine is required, and the operation is also very troublesome, thus affecting the installation and butt joint efficiency. When using the method of installing an external joint for butt joint, multiple bolts are required for fixation. When installing multiple bolts, it is more troublesome. It is necessary to align multiple bolt holes before the bolts can be screwed into the interior to achieve fixation, thereby reducing the butt joint efficiency of the silicon core pipe. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a cable silicon core pipe which is convenient for butt joint to solve the technical problem of inconvenient rapid butt joint of the silicon core pipe.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cable silicon core pipe which is convenient for butt joint, including a butt joint pipe. Two silicon core pipes are inserted into the interior of the butt joint pipe, and an installation ring is provided on the outer wall of the silicon core pipe. A butt joint component is arranged inside the butt joint pipe, and the butt joint component includes a limiting ring sleeved on the outer wall of the butt joint pipe, a plurality of grooves opened inside the butt joint pipe, and clamping grooves opened at both ends of the butt joint pipe. A clamping ring is clamped inside the clamping groove, and a locking hole is opened on the clamping ring. A spring is fixed inside the groove, and the end of the spring is connected with a locking column extending into the locking hole. A pressing rod penetrating to the outside of the butt joint pipe is installed on the locking column. An abutting groove is opened at one end of the limiting ring.

[0006] By adopting the above technical solution, when the pressing rod is pressed, it will drive the locking column to move, so that the locking column moves into the locking hole, and at the same time, the locking column will stretch the spring.

[0007] Furthermore, threads are provided on both sides of the inner wall of the limiting ring and the outer wall of the butt joint pipe, and the limiting ring is threadedly connected with the butt joint pipe.

[0008] By adopting the above technical solution, when the limiting ring moves and abuts against the pressing rod, the limiting ring can limit the pressing rod, so that the locking column can be firmly clamped into the locking hole.

[0009] Furthermore, anti-slip patterns are provided on the outer wall of the limiting ring.

[0010] By adopting the above technical solution, the anti-slip patterns facilitate the rotation of the limiting ring, and thus the limiting ring can move.

[0011] Furthermore, the locking column is adapted to the locking hole, and the locking column is slidably connected to the groove.

[0012] By adopting the above technical solution, when the spring contracts, it will drive the locking column into the groove, so that the locking column is removed from the locking hole.

[0013] Furthermore, the clamping groove is annular, and the clamping ring is adapted to the clamping groove.

[0014] By adopting the above technical solution, after the clamping ring is clamped into the clamping groove, the locking column is aligned with the locking hole, so that the locking column can be moved into the locking hole, and thus the clamping ring can be locked and fixed.

[0015] Furthermore, a wear-resistant layer is provided on the outer wall of the silicon core pipe.

[0016] By adopting the above technical solution, the wear-resistant layer can play a wear-resistant role, and thus improve the wear resistance of the silicon core pipe.

[0017] Furthermore, the end of the pressing rod is beveled, and the end of the pressing rod fits against the inner wall of the abutting groove.

[0018] By adopting the above technical solution, the pressing rod can be limited to prevent the pressing rod from moving randomly, and the stability of the pressing rod is improved.

[0019] Furthermore, one end of the clamping ring is connected to the mounting ring, and one end of the mounting ring fits against the end of the docking pipe.

[0020] By adopting the above technical solution, the mounting ring can block both ends of the docking pipe, and thus improve the sealing performance of the mounting ring.

[0021] Furthermore, the silicon core pipe is detachably connected to the docking pipe through the mounting ring and the clamping ring.

[0022] By adopting the above technical solution, the silicon core pipe can be quickly docked, and at the same time, the silicon core pipe can be detached from the docking pipe.

[0023] Further, the docking component further includes positioning grooves formed above and below both ends of the docking pipe. Positioning blocks are inserted into the positioning grooves, and the positioning blocks are connected to the mounting ring.

[0024] By adopting the above technical solution, when the silicon core pipes need to be docked, the positioning blocks on one side of the mounting ring can be inserted into the positioning grooves to position the mounting ring, so that the locking columns are aligned with the locking holes.

[0025] To sum up, the main beneficial effects of the present utility model are as follows:

[0026] With the docking component provided in the present utility model, when the silicon core pipes need to be docked, the end of the silicon core pipe can be inserted into the docking pipe, and the clamping ring and the positioning block on one side of the mounting ring are respectively clamped into the clamping groove and the positioning groove. At this time, the locking hole on the clamping ring will be aligned with the locking column. Then, rotate the limiting ring to make the limiting ring move. When the pressing rod enters the abutting groove, as the limiting ring continues to move, it will push the pressing rod downward, and the pressing rod will drive the locking column downward, so that the locking column moves into the locking hole to lock the clamping ring, and at the same time stretch the spring. When the locking column completely moves into the locking hole, stop rotating the limiting ring. In this way, the docking of the silicon core pipes can be completed. When disassembling the silicon core pipes, just rotate the limiting ring in the reverse direction so that the limiting ring no longer limits the pressing rod. At this time, the spring contracts and drives the locking column to move back, and the locking column moves out of the locking hole and no longer limits and fixes the clamping ring. Then, the silicon core pipes can be taken out. In this way, the silicon core pipes can be quickly docked, and the operation process is simple and convenient. There is no need to use multiple bolts or a hot melt machine for docking, which simplifies the operation steps and improves the docking and disassembly efficiency of the silicon core pipes.

[0035] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0036] Embodiment 1:

[0037] A cable silicon core pipe that is convenient for docking, as Figures 1 - 6 shown, includes a docking pipe 1. Two silicon core pipes 2 are inserted into the inside of the docking pipe 1. An installation ring 4 is provided on the outer wall of the silicon core pipe 2. A docking component 5 is provided inside the docking pipe 1. The docking component 5 includes a limiting ring 501 sleeved on the outer wall of the docking pipe 1, a plurality of grooves 506 opened inside the docking pipe 1, and card slots 510 opened at both ends of the docking pipe 1. A snap ring 509 is clamped inside the card slot 510, and a locking hole 508 is opened on the snap ring 509. A spring 505 is fixed inside the groove 506, and a locking column 507 extending into the locking hole 508 is connected to the end of the spring 505.

[0038] Specifically, a pressing rod 504 penetrating to the outside of the docking pipe 1 is installed on the locking column 507. The end of the pressing rod 504 is in an inclined shape. The end of the pressing rod 504 fits against the inner wall of the abutting groove 503 to limit the pressing rod 504 and prevent the pressing rod 504 from moving randomly, improving the stability of the pressing rod 504. When the pressing rod 504 is pressed, it will drive the locking column 507 to move, so that the locking column 507 moves into the locking hole 508. At the same time, the locking column 507 will stretch the spring 505. Threads are provided on both sides of the inner wall of the limiting ring 501 and the outer wall of the docking pipe 1. The limiting ring 501 is threadedly connected to the docking pipe 1. After the limiting ring 501 moves and the abutting groove 503 abuts against the pressing rod 504, the limiting ring 501 can limit the pressing rod 504, and then the locking column 507 is firmly clamped into the locking hole 508. An abutting groove 503 is opened at one end of the limiting ring 501.

[0039] Specifically, one end of the snap ring 509 is connected to the mounting ring 4, one end of the mounting ring 4 is attached to the end of the docking pipe 1, and the mounting ring 4 can seal both ends of the docking pipe 1, thereby improving the sealing performance of the mounting ring 4. The silicon core pipe 2 is detachably connected to the docking pipe 1 through the mounting ring 4 and the snap ring 509, so as to quickly dock the silicon core pipe 2, and at the same time, the silicon core pipe 2 can also be detached from the docking pipe 1.

[0040] Specifically, the outer wall of the limit ring 501 is provided with anti-slip threads 502. The anti-slip threads 502 are provided to facilitate the rotation of the limit ring 501, thereby moving the limit ring 501. The locking column 507 is adapted to the locking hole 508, and the locking column 507 is slidably connected to the groove 506. When the spring 505 contracts, it will drive the locking column 507 into the groove 506, so that the locking column 507 moves out of the locking hole 508. The card slot 510 is annular, and the snap ring 509 is adapted to the card slot 510. After the snap ring 509 is inserted into the card slot 510, the locking column 507 is aligned with the locking hole 508, so that the locking column 507 can be moved into the locking hole 508, thereby locking and fixing the snap ring 509.

[0041] Embodiment 2:

[0042] On the basis of the above Embodiment 1, in order to improve the wear resistance of the silicon core pipe 2, the following structure is provided.

[0043] Refer to Figures 1 - 2 , a wear-resistant layer 3 is provided on the outer wall of the silicon core pipe 2. The wear-resistant layer 3 can play a wear-resistant role, thereby improving the wear resistance of the silicon core pipe 2.

[0044] Embodiment 3:

[0045] On the basis of the above Embodiment 1, in order to align the locking hole 508 on the snap ring 509 with the locking column 507 after the snap ring 509 is inserted into the card slot 510, the following structure is provided.

[0046] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , the docking assembly 5 further includes positioning slots 512 opened above and below both ends of the docking pipe 1. The positioning blocks 511 are inserted into the positioning slots 512, and the positioning blocks 511 are connected to the mounting ring 4. When the silicon core pipe 2 needs to be docked, the positioning blocks 511 on one side of the mounting ring 4 can be inserted into the positioning slots 512 to position the mounting ring 4, so that the locking column 507 is aligned with the locking hole 508.

[0047] The working principle of the present utility model is as follows: First, when it is necessary to butt the silicon core pipes, the end of the silicon core pipe can be inserted into the butting pipe 1, and the snap ring 509 and the positioning block 511 on one side of the mounting ring 4 are respectively snapped into the internal card slot 510 and the positioning slot 512. At this time, the locking hole 508 on the snap ring 509 will be aligned with the locking column 507. Then, rotate the limiting ring 501, causing the limiting ring 501 to move. When the pressing rod 504 enters the abutting groove 503, as the limiting ring 501 continues to move, it will push the pressing rod 504 downward. The pressing rod 504 drives the locking column 507 to move downward, so that the locking column 507 is moved into the locking hole 508 to lock the snap ring 509, and at the same time, the tension spring 505 is stretched. When the locking column 507 is completely moved into the locking hole 508, stop rotating the limiting ring 501. In this way, the butt joint of the silicon core pipe 2 can be completed. When disassembling the silicon core pipe 2, just rotate the limiting ring 501 in the reverse direction, so that the limiting ring 501 no longer limits the pressing rod 504. At this time, the spring 505 contracts, driving the locking column 507 to reset and move, and the locking column 507 is moved out of the locking hole 508 and no longer limits and fixes the snap ring 509. Then, the silicon core pipe 2 can be taken out. In this way, the silicon core pipe 2 can be quickly butted.
