[0033] Furthermore, when it is necessary to fix the mounting column 1, first, the bottom end of the conical block 2 is fitted with the designated ground. At this time, the mounting column 1 is perpendicular to the ground, and a tool is used to drive the mounting column 1 into the ground until the bottom of the screw is completely inserted into the ground. At this time, the rocker 6 is rotated to drive the worm 16 to rotate through the rocker 6, and then the worm gear 15 is driven to rotate through engagement. Under the action of the worm gear 15, the threaded rod 10 drives the threaded block 11 to move along the inner wall of the limiting column 9, and the moving rod 12 pushes the fixing rod 7 to move along the inner wall of the mounting groove 22, so that one end of the fixing rod 7 extends out of the mounting groove 22, and the mounting column 1 is further fixed. When it is necessary When it is necessary to remove the mounting column 1, turn the rocker 6 and repeat the above steps. The moving rod 12 pulls the fixing rod 7 to one side, so that the fixing rod 7 is disengaged from the inner wall of the mounting groove 22, so that the end of the fixing rod 7 away from the moving rod 12 stays in the gap between the connecting column 8 and the mounting column 1. The mounting column 1 is pulled upward to pull the mounting column 1 out of the ground, and the removal of the mounting column 1 is completed, which is convenient for power personnel to inspect and replace wiring equipment and reduce safety risks. The function of the threaded block 11 is to drive the moving rod 12 to rotate, and the function of the connecting column 8 is to limit the fixing rod 7, so that the outer side of the fixing rod 7 is always in contact with the inner wall of the connecting groove 21 to prevent the fixing rod 7 from sliding into the inside of the connecting column 8.

[0034] Reference Figure 3 , Figure 4 and Figure 6 The disassembly assembly includes a connecting column 3, the bottom of which is fixedly connected to the top of the mounting column 1, two wiring grooves 4 are provided on the outside of the connecting column 3, two wiring boards 13 are fixedly connected to the inner wall of the connecting column 3, two internal grooves 17 are provided on the inner wall of the connecting column 3, a baffle 19 is slidably connected to the inner wall of the internal groove 17, a pull rod 5 is fixedly connected to one side of the baffle 19, a spring 18 is sleeved on the outside of the pull rod 5, a clamping block 20 is fixedly connected to the other end of the baffle 19, and two clamping grooves 14 are provided on the outside of the mounting column 1.

[0035] Furthermore, when it is necessary to remove the connecting column 3, pull the pull rod 5 outward, and then the pull rod 5 drives the baffle 19 to slide along the inner wall of the internal groove 17, and the baffle 19 drives the block 20 to slide until the block 20 is completely retracted into the interior of the internal groove 17. At this time, remove the connecting column 3 to complete the disassembly of the connecting column 3. When it is necessary to install the connecting column 3, pull the pull rod 5 and repeat the above steps. At this time, the spring 18 is in a compressed state, release the pull rod 5, and under the elastic force of the spring 18, the baffle 19 is reset, and then the outside of the block 20 fits against the inner wall of the slot 14 to complete the installation of the connecting column 3. By disassembling and installing the connecting column 3, a certain flexibility and scalability are provided for the wiring port, which makes the wiring system easier to adjust and adapt to changing needs.

[0036] Reference Figure 2 The longitudinal section of the threaded block 11 is square, and the outside of the threaded block 11 is slidably connected to the inner wall of the limiting column 9.

[0037] Furthermore, when the threaded rod 10 rotates, the threaded block 11 slides along the inner wall of the limiting column 9, preventing the threaded block 11 from rotating with the threaded rod 10, thereby ensuring the effectiveness of the structure.

[0038] Reference Figure 2 and Figure 5 The outside of the worm wheel 15 is meshedly connected with the outside of the worm 16 at the corresponding position.

[0039] Furthermore, the worm 16 drives the worm wheel 15 to rotate through meshing, so that the worm wheel 15 rotates more stably.

[0041] Furthermore, the function of the scraper is to make the conical block 2 smoother when inserted into the ground and reduce resistance, and the function of the screw is to further fix the mounting column 1 to prevent natural factors from causing the mounting column 1 to shake and affect the stability of the connection of the wiring port.

[0042] Reference Figure 4 and Figure 6 The shape of the card block 20 matches the card slot 14 , and the card block 20 and the card slot 14 are plug-fitted.

[0043] Furthermore, the clamping block 20 is clamped into the clamping slot 14 to further fix the connecting column 3, so that the connection between the mounting column 1 and the connecting column 3 is more stable.

[0044] Reference Figure 4 and Figure 6One end of the spring 18 is fixedly connected to the outer side of the baffle 19 , and the other end of the spring 18 is fixedly connected to the inner wall of the internal groove 17 .

[0045] Furthermore, the baffle 19 is limited by the spring 18 to prevent the baffle 19 from sliding freely along the inner wall of the inner groove 17 , causing the block 20 to be separated from the groove 14 , thereby further improving the stability of the connecting column 3 .

[0046] Reference Figure 2 The longitudinal section of the fixing rod 7 is square, and the outer portion of the fixing rod 7 is slidably connected to the inner wall of the mounting groove 22 .

[0048] Working principle: When the mounting column 1 needs to be fixed, first, the bottom end of the conical block 2 is fitted to the designated ground. At this time, the mounting column 1 is perpendicular to the ground. Use a tool to drive the mounting column 1 into the ground until the bottom of the screw is completely inserted into the ground. At this time, turn the rocker 6 to drive the worm 16 to rotate, and then drive the worm wheel 15 to rotate. The worm wheel 15 drives the threaded rod 10 to rotate. Under the action of the threaded rod 10, the threaded block 11 is driven to move. At the same time, the threaded block 11 drives the moving rod 12 to rotate at the same time, and the moving rod 12 pushes the fixed The rod 7 moves along the inner wall of the mounting groove 22, so that one end of the fixing rod 7 extends out of the mounting groove 22, further fixing the mounting column 1, and completing the fixation of the mounting column 1. When the mounting column 1 needs to be removed, the rocker 6 is rotated, and the above steps are repeated. The moving rod 12 pulls the fixing rod 7 to one side, so that the fixing rod 7 is disengaged from the inner wall of the mounting groove 22, and the mounting column 1 is pulled upward to pull the mounting column 1 out of the ground, completing the removal of the mounting column 1, making it more convenient for power personnel to install and remove the terminal posts, thereby improving equipment utilization.

[0049] In addition, when it is necessary to disassemble the connecting column 3, pull the pull rod 5, the pull rod 5 drives the baffle 19 to slide, and the baffle 19 drives the block 20 to slide at the same time, so that the block 20 is disengaged from the slot 14. At this time, remove the connecting column 3 to complete the disassembly of the connecting column 3. When it is necessary to install the connecting column 3, pull the pull rod 5 and repeat the above steps. At this time, the spring 18 is in a compressed state, release the pull rod 5, and under the elastic force of the spring 18, the block 20 is stuck in the slot 14 to complete the installation of the connecting column 3, making it more convenient for power personnel to maintain and replace the wiring ports.
