The fixed half ring 12 is used to connect with the pipe for threading the pipe, and is fixed by plugging into the pipe through the plug-in block 13. The plug-in block 13 is a hollow structure, and the connecting ring 1 can be plugged in more stably by adding a counterweight and pressed against the pipe orifice of the pipe. A connecting slider 4 is movably sleeved on the sliding half ring 11, and a connecting plate 2 is connected to the side of the connecting slider 4 away from the sliding half ring 11, and two groups of connecting side plates 21 are connected to the side of the connecting plate 2 away from the connecting slider 4. A guide pulley 3 is connected between the two groups of connecting side plates 21, and the cable is guided and limited when passing through the guide pulley 3. The position of the guide pulley 3 can be adjusted by moving the connecting slider 4 in the position of the sliding half ring 11 according to the transmission and pulling direction of the cable to meet the actual needs during the cable installation process.

[0024] like Figure 3As shown, the end of the connecting side plate 21 away from the connecting plate 2 is connected to a connecting bearing 211, and both sides of the guide pulley 3 are connected to the limiting plates 31. The side of the limiting plate 31 away from the guide pulley 3 is connected to a connecting shaft 32 inserted in the connecting bearing 211, and the end of the connecting shaft 32 away from the limiting plate 31 is connected to a limiting collar 321. The guide pulley 3 is inserted into the connecting bearing 211 on the connecting side plate 21 through the connecting shaft 32 to complete the connection with the connecting plate 2, and the limiting collar 321 on the connecting shaft 32 can prevent the guide pulley 3 from sliding off the connecting side plate 21, and the limiting plate 31 on the guide pulley 3 limits the cable passing through the guide pulley 3 to prevent the cable from moving away from the guide pulley 3 during the process of passing through the pipe.

[0025] like Figure 2 , 3 As shown in Figure 4, the connecting slider 4 includes a connecting sleeve 42 arranged at the connection between the connecting slider 4 and the sliding half ring 11 and a fixing knob 41 arranged at the top of the connecting slider 4. A fixing bolt 411 is arranged at the connection between the fixing knob 41 and the connecting slider 4. A sliding protrusion 421 that engages with the sliding track 111 is arranged inside the connecting sleeve 42, and an auxiliary pulley 422 is connected to the inner side of the connecting sleeve 42 away from the fixing bolt 411. During the sliding process of the connecting slider 4 on the sliding half ring 11, the sliding protrusion 421 is inserted into the sliding track 111 to limit the position of the sliding track of the connecting slider 4 and the direction of the guide pulley 3. During the sliding process of the connecting slider 4, the auxiliary pulley 422 assists the sliding of the connecting slider 4, making it easier to adjust the sliding of the connecting slider 4. When the connecting slider 4 and the guide pulley 3 connected to it move to a suitable position, the fixing knob 41 is turned to make the fixing bolt 411 press the sliding half ring 11, thereby fixing the position of the connecting slider 4 on the sliding half ring 11.

The plug-in block 13 can make the connecting ring 1 more stable by adding a counterweight, and counterweights such as sand, stone and iron powder are added to the plug-in block 13 through the feed port 131, and the feed port 131 can be sealed and blocked by the sealing plug cover 14, so that the connecting ring 1 is pressed against the pipe mouth of the pipeline under the action of gravity, and the counterweight in the plug-in block 13 can be discharged and recovered from the discharge port 133 at the bottom, and opened and closed by the connecting plug 15, and the groove 132 at the bottom of the plug-in block 13 can make the plug-in block 13 fit more closely with the pipe mouth, preventing the connecting plug 15 from protruding.

[0027] Working principle: When using a cable pipe guide device that can be adjusted at multiple angles, the connecting ring 1 can first be added with a counterweight to make the connection more stable, and counterweights such as sand, stone, and iron powder can be added to the plug block 13 from the feed port 131. The feed port 131 can be sealed and blocked by a sealing plug cover 14, and then the plug block 13 is plugged into the designated pipeline. The connecting ring 1 and the plug block 13 are pressed against the pipe mouth of the pipeline under the action of gravity, and the position of the guide pulley 3 can be adjusted by moving the connecting slider 4 at the position of the sliding half ring 11 according to the transmission and pulling direction of the cable.

[0028] The connecting slider 4 slides on the sliding half ring 11, and during the sliding process of the connecting slider 4, the position of the connecting slider 4 is limited by the sliding protrusion 421 inserted in the sliding track 111 to limit the sliding track and the direction of the guide pulley 3, and the connecting slider 4 is assisted by the auxiliary pulley 422 to slide the connecting slider 4 during the sliding process, so that the connecting slider 4 can adjust the sliding more easily, and when the connecting slider 4 and the guide pulley 3 connected to it are moved to the appropriate position, the fixing knob 41 is turned to make the fixing bolt 411 press the sliding half ring 11, thereby fixing the position of the connecting slider 4 on the sliding half ring 11.

[0029] When the cable passes through the guide pulley 3, the guide pulley 3 rotates in the connecting bearing 211 on the connecting side plate 21 through the connecting shaft 32, and the limiting ring 321 on the connecting shaft 32 can prevent the guide pulley 3 from sliding off the connecting side plate 21, and the limiting plate 31 on the guide pulley 3 limits the cable passing through the guide pulley 3 to prevent the cable from moving away from the guide pulley 3 during the process of threading the pipe, and the counterweight in the plug block 13 can be discharged and recovered from the discharge port 133 at the bottom, and opened and closed through the connecting plug 15, and the groove 132 at the bottom of the plug block 13 can make the plug block 13 fit more closely with the pipe mouth to prevent the connecting plug 15 from protruding.
