[0001] The utility model relates to the technical field of cable installation pipe groups, in particular to a weak current cable installation pipe group. Background Art

[0002] Where low-current cables enter buildings, tunnels, pass through floors and walls, and are led from the ground to poles, equipment, the outer surface of walls or places easily accessible to pedestrians, at a height of less than two meters from the ground, and other places that may be subject to mechanical damage, protective pipe groups should be installed to protect the low-current cables from mechanical damage.

[0003] However, the existing weak-current cable installation pipe group is usually composed of a plurality of protective pipes arranged in combination. Due to the large cross-section of the plurality of protective pipes, the space available for fixing the pipe group is small, so that a single pipe in the pipe group is easily restricted by distance and position during fixed installation, which is not conducive to the rapid fixed installation of the pipe group. In addition, when the existing installation pipe group passes through the weak-current cables, different cables are usually inserted into the protective pipes arranged at different positions one by one in turn, which results in a long time for the weak-current cables to pass through the pipe group.

[0010] Preferably, the rotating ring is movably connected to the sliding disk through a limiting ring.

[0011] Preferably, the internal threaded barrel is movably connected to the circular plate via a screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The weak current cable installation pipe group, through the sliding plate, swivel, fixed bracket and limit ring, makes the fixed position of the installation pipe group can be flexibly adjusted according to the position of the space available for fixation, and at the same time, each pipe in the pipe group can be fixed at the same time, reducing the space restriction on the fixed installation of the pipe, thereby facilitating the rapid installation and fixation of the pipe group.

[0023] like Figures 1 to 4As shown, the weak-current cable installation pipe group of this embodiment includes a first chuck 2. The diameters of the first chuck 2 and the second chuck 7 are the same. At the same time, the first chuck 2 and the second chuck 7 can fix the heads and tails of multiple pipes 3 at the same time, so that the pipe group has higher stability when in use. Multiple pipes 3 are passed through the middle of the first chuck 2. The pipes 3 are ordinary plastic pipes 3, which mainly play a role in protecting the weak-current cables passing through the wall. At the same time, the lengths of the multiple pipes 3 are the same. The end of the pipe 3 away from the first chuck 2 is sleeved with the second chuck 7. The outer wall of the pipe 3 is movably sleeved with a sliding plate 4. The sliding plate 4 is Made of silicone, it is wear-resistant and not easy to deform, so that multiple pipes 3 can still maintain a better gap after being fixed, reducing the probability of deformation of a single pipe 3 in the pipe group. The outer wall of the sliding plate 4 is fixedly connected to the limiting ring 13, which is located in the middle of the outer wall of the sliding plate 4 and has a smooth surface. Its function is to enable the swivel 5 to maintain connection with the sliding plate 4 and reduce the probability of the swivel 5 being separated from the sliding plate 4. The outer wall of the limiting ring 13 is movably sleeved with a swivel 5, and the inner diameter of the swivel 5 is adapted to the outer diameter of the sliding plate 4. At the same time, a sliding groove is opened in the middle of the swivel 5, and the inner wall of the sliding groove fits the outer wall of the limiting ring 13. , so that the swivel 5 can rotate along the limit ring 13 on the outer wall of the sliding plate 4, so as to realize the flexible adjustment of the direction of the fixed bracket 6, so that the fixed bracket 6 can be rotated to a position with a larger space for fixing, thereby reducing the space limitation of the pipe group during fixed installation. The top of the swivel 5 is fixedly connected to the fixed bracket 6, and the fixed bracket 6 is also provided with a screw hole for inserting an expansion bolt, so that the pipe group can be fixed in a suitable position by the expansion bolt. A traction line 12 is provided inside the pipeline 3. The traction line 12 is a steel wire that is not easy to be torn off. One end of the traction line 12 is fixedly connected to A screw 10 is connected, and the screw 10 is an externally threaded rod, so that the internally threaded barrel 11 can engage the screw 10 and move toward the circular plate 9. One end of the screw 10 is fixedly connected to the circular plate 9, and a rubber pad is fixed to the side wall of the circular plate 9 close to the internally threaded barrel 11, so that the internally threaded barrel 11 and the circular plate 9 are not easy to fall off after clamping the low-voltage cable, thereby facilitating the subsequent pulling of the low-voltage cable by the traction line 12. The internally threaded barrel 11 is provided on the outer wall of the screw 10 with a movable thread sleeve, and the diameter of the internally threaded barrel 11 is the same as the diameter of the circular plate 9, so that the circular plate 9 and the internally threaded barrel 11 can better clamp the low-voltage cable.

[0024] Specifically, a pipe opening 1 is provided at the junction of the pipe 3, the first chuck 2 and the second chuck 7. The pipe opening 1 on the side wall of the first chuck 2 is movably connected to the circular plate 9. The function of the pipe opening 1 on the first chuck 2 is to facilitate the clamping of the joint of the low-voltage cable with the circular plate 9 and the internal threaded tube 11, thereby facilitating the subsequent traction of the cable.

[0025] Furthermore, a plug post 15 is movably inserted through the pipe opening 1 on one side wall of the second chuck 7, one end of the plug post 15 is fixedly connected to the traction line 12, and the outer diameter of the plug post 15 is adapted to the inner diameter of the pipe 3, so that the cover plate 8 can be clamped on the second chuck 7, while keeping one end of the pipe 3 closed, reducing the probability of foreign matter entering the pipe 3.

[0026] Furthermore, the plug post 15 is movably connected to the pipeline 3 , and the traction line 12 is movably connected to the pipeline 3 through the plug post 15 . The entire traction line 12 is buried in the pipeline 3 , which can protect the traction line 12 and extend the service life of the traction line 12 .

[0027] Furthermore, one end of the plug post 15 away from the traction line 12 is fixedly connected with a cover plate 8, and the cover plate 8 is movably connected to the second chuck 7 through the plug post 15. A side wall of the cover plate 8 away from the plug post 15 is fixedly connected with a clamping block 14, and the clamping block 14 is a square block, which is convenient for the user to pull the cover plate 8 out of the pipe mouth 1 on the second chuck 7, thereby realizing the separation of the plug post 15 and the pipe mouth 1.

[0028] Furthermore, the swivel 5 is movably connected to the sliding plate 4 through a limit ring 13. The rotation of the swivel 5 along the limit ring 13 can drive the fixed bracket 6 to rotate along the outer side of the sliding plate 4, thereby facilitating the flexible adjustment of the fixed position of the pipe group and reducing the restrictions on the pipe group during fixed installation.

[0029] Furthermore, the internal threaded barrel 11 is movably connected to the circular plate 9 through the screw rod 10. After the internal threaded barrel 11 approaches the circular plate 9 along the screw rod 10, the low-voltage cable can be clamped in the gap between the circular plate 9 and the internal threaded barrel 11, so that the traction line 12 is fixed to the end of the low-voltage cable, thereby facilitating the subsequent traction line 12 to pull the low-voltage cable.

[0030] The method of using this embodiment is as follows: when fixing the weak-current cable installation pipe group, the sliding plate 4 can be slid to a suitable position along the outer wall of the pipe 3 first, and then the rotating ring 5 can be rotated to make the rotating ring 5 rotate along the limiting ring 13 of the outer wall of the sliding plate 4, and at the same time drive the fixing bracket 6 of the outer wall to rotate, so that the fixing bracket 6 can be rotated to a position with a larger space for fixing. When different weak-current cables need to pass through different pipes 3, the ends of different cables can be respectively pressed against the circular plates 9 in the pipe opening 1 on the first chuck 2, and then the corresponding internal threaded barrel 11 can be screwed so that the internal thread The grooved cylinder 11 moves along the screw 10 to the side of the circular plate 9 where the cable end is attached, until the internal threaded cylinder 11 and the circular plate 9 clamp the cable end, and then the remaining cables are fixed to the circular plate 9 in the above manner. Then the clamping block 14 can be pinched to pull the cover plate 8 from one side of the second chuck 7, so that the plug post 15 on the second chuck 7 is pulled out from the pipe opening 1 on the second chuck 7, and at the same time, the plug post 15 will drive the traction line 12 to slide out of the pipe 3, so that the traction line 12 drives the cable clamped by the circular plate 9 to pass into the pipe 3, and then pass out from the pipe opening 1 of the second chuck 7.
