Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe installation technology, and in particular to a fixing structure for cable protection pipe installation. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength laid on the outer layer of cables to prevent damage. They are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes, thus protecting cables and switches from burning out. They also provide some isolation against magnetic field interference from power lines. During installation, several cable protection pipes need to be connected by fasteners to achieve the purpose of layered laying and fixing of the cables.

[0003] When installing existing cable protection pipes, a fixing structure is used. However, the commonly used fixing structure is not very adaptable to cable protection pipes of different sizes. The fixing operation is also quite cumbersome. Moreover, since it is mostly fixed by studs and nuts, it will gradually rust under the erosion of rainwater over a long period of time, which is not conducive to the subsequent removal of the cable protection pipe for maintenance. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies of the existing technology by providing a fixing structure for cable protection pipe installation, thereby solving the problems mentioned in the background art.

[0005] A fixing structure for installing cable protection pipes includes a support, with limiting parts installed on both sides of the support. At least one set of studs is installed at the top of the support. A cylindrical sleeve is detachably fitted on the top of the support. A limiting part two is installed on the outer wall of the cylindrical sleeve and is rotatably connected by a ring. The limiting part two can be inserted into the slot of the limiting part one to fix the cable protection pipes together with the limiting part. The studs penetrate the top of the cylindrical sleeve and the upward freedom of the cylindrical sleeve can be restricted by a nut.

[0006] By adopting the above technical solution, cable protection pipes can be installed quickly and easily, and the pipes are highly adaptable to fixing different sizes of cable protection pipes.

[0007] The top of the cylindrical sleeve is also provided with a threaded groove, and an end cap is rotatably mounted at the threaded groove.

[0008] By adopting the above technical solution, the connectors can be prevented from being corroded by rainwater for a long time, which would make it difficult to disassemble the cable protection pipe.

[0009] The bottom plate of the limiting part one is fixed to the outer wall of the support, and its side plate extends upward at an angle. The top plate of the limiting part two is fixed to the ring, and its side plate extends downward at an angle.

[0010] By adopting the above technical solution, the cable protection pipe can be stably positioned.

[0011] The inner side of the cylindrical sleeve has a circular opening from the middle to the bottom, the diameter of which is adapted to the diameter of the upper end of the support. A threaded hole is provided at the top of the cylindrical sleeve.

[0012] The above technical solution facilitates the restriction of column sleeves.

[0013] The stud is provided in three parts, and the top of the stud sleeve is also provided with three threaded holes, the diameter of which is adapted to the threaded holes.

[0014] By adopting the above technical solutions, the stability of cable protection pipe restrictions is increased.

[0015] The beneficial effects of the fixing structure for cable protection pipe installation of this utility model are:

[0016] 1. Install the support at the predetermined position. Place the cable protection pipe on the limiting part one to support it. Then, put the cylindrical sleeve on the top of the support and let the stud pass through the top of the cylindrical sleeve. At this time, the limiting part two is embedded in the groove of the limiting part one. The cable protection pipe is then limited by the limiting part one and the limiting part two. Rotate the nut onto the stud to limit the cylindrical sleeve, thus completing the fixing of the cable protection pipe. This facilitates quick installation of the cable protection pipe and has high adaptability to fixing cable protection pipes of different sizes.

[0017] 2. Rotating the end cap to the threaded groove of the cylindrical sleeve can protect the stud and nut, preventing the connector from being corroded by rainwater for a long time, which would make it difficult to disassemble the cable protection tube. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-3 A fixing structure for installing cable protection pipe includes a support 1, with limiting parts 2 installed on both sides of the support 1, and at least one set of studs 3 installed at the top of the support 1. A columnar sleeve 4 is detachably fitted on the top of the support 1. A second limiting part 6 is installed on the outer wall of the columnar sleeve 4 and is rotatably connected by a ring 5. The second limiting part 6 can be inserted into the slot of the first limiting part 2 to fix the cable protection pipe in conjunction with the first limiting part 2. The studs 3 penetrate the top of the columnar sleeve 4 and the upward freedom of the columnar sleeve 4 can be restricted by a nut 7.

[0024] Install the support 1 at the predetermined position, and place the cable protection tube on the limiting part 2 to support it. Then, put the cylindrical sleeve 4 on the top of the support 1, so that the stud 3 passes through the top of the cylindrical sleeve 4. At this time, the limiting part 6 is embedded in the groove of the limiting part 2, and the cable protection tube is limited by the limiting part 2 and the limiting part 6. Then, rotate the nut 7 onto the stud 3 to limit the cylindrical sleeve 4, thus completing the fixation of the cable protection tube. Then, rotate the end cap 8 to the threaded groove 401 of the cylindrical sleeve 4 to protect the stud 3 and the nut 7.

[0025] The top of the cylindrical sleeve 4 is also provided with a threaded groove 401, and an end cap 8 is rotatably mounted at the threaded groove 401.

[0026] The bottom plate of the limiting part 1 2 is fixed to the outer wall of the support 1, and its side plate extends upward at an angle. The top plate of the limiting part 2 6 is fixed to the ring 5, and its side plate extends downward at an angle.

[0027] The inner side of the cylindrical sleeve 4 has a circular opening from the middle to the bottom. The diameter of the circular opening is adapted to the diameter of the upper end of the support 1. A threaded hole is provided at the top of the cylindrical sleeve 4. Before the cylindrical sleeve 4 is placed on the support 1, the limiting part 2 6 is inserted into the groove of the limiting part 1 2, and then the cylindrical sleeve 4 is placed downward so that the upper end of the support 1 first extends into the bottom of the cylindrical sleeve 4. There are three studs 3, and the top of the cylindrical sleeve 4 also has three threaded holes. The diameter of the studs 3 is adapted to the threaded holes. Rotate the cylindrical sleeve 4 to adjust the position of the threaded groove 401 so that the studs 3 correspond one by one with the threaded holes on the cylindrical sleeve 4, so that the studs 3 can pass through the threaded holes of the cylindrical sleeve 4. Because the cylindrical sleeve 4 is designed to increase its length, when the top of the support 1 contacts the upper end plate of the cylindrical sleeve 4, the limiting part 2 6 has already contacted the cable protection tube. At this time, tighten the nut 7 to restrict the freedom of the cylindrical sleeve 4 to move upward, and the cable protection tube can be positioned.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
