[0047] As a preferred implementation of this embodiment, Figure 6 As shown, the control mechanism includes two fixed rods 21, two connecting rods 22, two insertion rods 23 and four positioning springs 24.

[0050] Furthermore, after the positioning block is inserted into the positioning groove, the positioning block can block the positioning rod 7 from moving in the housing 6 , so that the positioning rod 7 can be positioned in the housing 6 .

[0051] In this embodiment, Figure 7 As shown, the blocking rod 15 is slidably connected to the front side of the pushing frame 14, the blocking rod 15 is fixedly connected to the reset spring 19, the reset spring 19 is fixedly connected to the fixed plate 18, the fixed plate 18 is fixedly installed on the front side of the pushing frame 14, the blocking rod 15 is rotatably connected to the pulling rod 16, the pulling rod 16 is rotatably connected to the pulling frame 17, and the pulling frame 17 is slidably connected to the front side of the pushing frame 14.

[0052] Furthermore, the blocking rod 15 is used to block the movement of the pushing frame 14, so that the pushing frame 14 can continuously push the fitting block 8 to separate from the matching rod 11 and the positioning rod 7, thereby continuously unlocking the positioning rod 7 and facilitating the disassembly of the positioning rod 7 and the outer tube 5.

[0053] In this embodiment, Figure 8 As shown, the inner wall of the docking shell 20 is fixedly mounted with limiting rods 25 arranged in a matrix. There are four limiting rods 25 . The limiting rods 25 are respectively fixedly connected to the positioning springs 24 . The limiting rods 25 are in sliding contact with the docking plate 26 .

[0054] Furthermore, the limiting rod 25 is used to limit the position of the docking plate 26 in the docking shell 20 so that the docking plate 26 can be accurately inserted into the docking shell 20 and then cooperate with the positioning spring 24 so that the positioning spring 24 can be stretched by the insertion rod 23.

[0055] In this embodiment, Figure 6As shown, the docking plate 26 is provided with symmetrically arranged insertion grooves, the number of which is two, and the sides of the two insertion rods 23 that are close to each other are in sliding contact with the sides of the two insertion grooves that are close to each other.

[0056] Furthermore, after the insertion rod 23 is inserted into the insertion groove, the insertion rod 23 can block the movement of the docking plate 26 in the docking shell 20, thereby achieving the positioning of the docking plate 26.

[0057] The present invention also proposes a method for using a city communication pipeline with a built-in cable partition mechanism, comprising the following steps:

[0058] S1: When it is needed, first insert multiple cables into the middle tube 2 and multiple outer tubes 5, and then install the outer tubes 5 in the pipeline 1;

[0059] S2: First, insert the positioning rod 7 on the outer tube 5 into the outer shell 6, and then the outer tube 5 can be installed in the pipeline 1;

[0060] S3: Then the middle tube 2 and the outer tube 5 can separate the cables;

[0061] S4: Then, the pulling frame 17 is pulled and the pushing ring 3 is pushed to disassemble the middle tube 2 and the outer tube 5, and the cable is disassembled.

[0062] Working principle: when it is necessary to partition the cables, it is only necessary to insert the cables into the middle tube 2 and multiple outer tubes 5, and then install the outer tubes 5 in the outer shell 6 in the pipeline 1, and insert the positioning rod 7 on the outer tube 5 into the outer shell 6. After the positioning rod 7 enters the outer shell 6, the bottom of the fitting block 8 is close to the bottom inner wall of the outer shell 6, and the gap is small. Then when the right side of the positioning rod 7 enters, the right end of the positioning rod 7 will enter between the bottom of the fitting block 8 and the bottom inner wall of the outer shell 6, and then lift up the fitting block 8, so that the fitting block 8 drives the matching rod 11 to rise, and then continue to insert the positioning rod 7. When the left end of the positioning rod 7 is separated from the fitting block 8, the compression spring 9 is compressed by the fitting block 8. When the fitting block 8 is released, the fitting block 8 will be reset by the rebound of the compression spring 9, and the matching rod 11 will fall into the top of the positioning rod 7, and the positioning block will enter the positioning groove at the top of the positioning rod 7. The right side of the fitting block 8 will also fit with the left side of the positioning rod 7. After the positioning block is inserted into the positioning groove, the positioning block can prevent the positioning rod 7 from moving in the outer shell 6, and the positioning rod 7 can be positioned in the outer shell 6. The positioning rod 7 will be installed in the outer shell 6, and the outer tube 5 will also be installed in the pipeline 1, so the cable can be installed in the pipeline 1. There is no contact between the middle tube 2 and the outer tube 5, so the cables can be separated, which can effectively reduce the interference between the cables and facilitate the maintenance of the cables.

[0063] When it is necessary to disassemble the middle tube 2 and the outer tube 5, it is only necessary to push the pushing frame 14 on the shell 6, and the pushing frame 14 pushes the pushing rod 13, and the pushing rod 13 pushes the telescopic rod 12 to rotate, and the telescopic rod 12 can drive the matching rod 11 to disengage from the fitting block 8, so as to unlock the positioning rod 7, and the positioning rod 7 can be pulled out of the shell 6. At the same time, when the pushing frame 14 is pushed to move, the blocking rod 15 will enter the shell 6 and disengage from the shell 6, and the return spring 19 is in a compressed state. The return spring 19 will push the blocking rod 15 to move downward, and the blocking rod 15 will fit with the left inner wall of the shell 6 to the left, so that the pushing frame 14 can be positioned, so that the sustainable pushing fitting block 8 and the matching rod 11 can be disengaged from the positioning rod 7, so as to sustainably unlock the positioning rod 7, and it is convenient to disassemble the positioning rod 7 from the shell 6.

[0064] Then pull the pulling frame, the pulling frame 17 pulls the pulling rod 16, and the pulling rod 16 can pull the blocking rod 15 to disengage from the inner wall of the outer shell 6, so as to unlock the fitting block 8 and the matching rod 11, and then disengage the middle tube 2 from the outer tube 5. First, push the pushing ring 3 on the middle tube 2, and the pushing ring 3 pushes the connecting rod 22. The connecting rod 22 pushes the fixing rods 21 away from each other. The two fixing rods 21 drive the two insertion rods 23 to disengage from the docking plate 26 and stretch the positioning spring 24. Then, the middle tube 2 can be disengaged from the outer tube 5, and the cable can be freed from the limit, which is convenient for cable maintenance.

[0065] Then insert the docking block 4 and the docking plate 26 on the outer tube 5 into the docking shell 20 and release the push ring 3. The insertion rod 23 is reset by the rebound of the positioning spring 24, and the positioning spring 24 will pull the insertion rod 23 to be inserted into the insertion groove on the docking plate 26. After the insertion rod 23 is inserted into the insertion groove, the insertion rod 23 can block the movement of the docking plate 26 in the docking shell 20, so as to realize the positioning of the docking plate 26, and the middle tube 2 and the outer tube 5 can be connected. Then, the middle tube 2 and the outer tube 5 are installed in the pipeline 1 to cut off the cables again.

[0066] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
