[0035] Referring to Figures 1-7 A pole locking structure, comprising a pre-buried base 10, a pole base 20 and a connecting assembly 30, the connecting assembly 30 is used for connecting the pre-buried base 10 and the pole base 20, the pre-buried base 10 is provided with a plurality of locking modules 40, and the locking module 40 can be locked and connected with the pole base 20. The locking module provided by the utility model further locks outside the connection of the connecting assembly, restricts the up-down position of the pole base and the pre-buried base, and improves the connection stability of the two.

[0036] Referring to Figure 4 and Figure 6 As shown, the locking module 40 comprises a moving block 410 movably arranged relative to the pre-buried base 10, and the moving block 410 is provided with a locking block 420; the pole base 20 is provided with a communication groove 230, and the communication groove 230 is provided with a locking groove 240 at the end; the moving block 410 can move between a first position and a second position relative to the pre-buried base 10; when the moving block 410 is located at the second position, the locking block 420 is inserted into the communication groove 230 to restrict the upward movement of the pole base 20 relative to the pre-buried base 10; the pole base 20 is provided with a driving assembly 400 for driving the moving block 410 to move from the first position to the second position.

[0037] As Figure 4As shown, the movable block 410 is in the first position. At this time, when the pole body 50 and pole base 20 are hoisted, the pole base 20 moves from top to bottom, gradually inserting the movable block 410 and locking block 420 into the communicating groove 230. Once the pre-embedded base 10 is in contact with the pole base 20, the connecting assembly 30 can be used for connection. After the connecting assembly 30 completes the connection, the driving assembly 400 drives the movable block 410 from the first position to the second position, so that the locking block 420 is inserted into the communicating groove 230. Figure 5 As shown.

[0038] See Figure 4 and Figure 6 The drive assembly 400 is equipped with an adjusting column 430 threadedly connected to the pole base 20.

A ramp 411 is located at the end of the moving block 410 near the tapered element 440, and the tapered surface of the tapered element 440 engages with the ramp 411. By rotating the adjusting column 430, the tapered element 440 can be moved upwards or downwards due to the threaded connection. The direction of movement is determined by the rotation direction of the adjusting column 430. When moving downwards, as the tapered element 440 gradually moves from top to bottom, its tapered surface engages with the ramp 411, driving the moving block 410 from a first position to a second position. Conversely, when the tapered element 440 gradually moves upwards, its tapered surface gradually moves away from the ramp 411, giving the moving block 410 space to return from the second position to the first position.

[0039] See Figure 4 and Figure 6 An elastic retaining element 450 is connected between the movable block 410 and the pre-embedded base 10; the elastic retaining element 450 is used to apply force to the movable block 410 so that the movable block 410 is held in the first position.

[0040] Furthermore, the elastic retaining element 450 is used to push the moving block 410 from the second position back to the first position.

[0041] Furthermore, the elastic retaining element 450 is a spring.

[0042] See Figure 4 The upper surface of the pre-embedded base 10 is provided with a downwardly recessed mounting cavity 110, the movable block 410 is movably disposed in the mounting cavity 110, and the connecting groove 230 is disposed on the lower surface of the pole base 20 and is interconnected with the mounting cavity 110.

[0043] See Figure 4 The mounting cavity 110 is provided with a guide groove 120, and the movable block 410 is equipped with a guide member 460, which is movably inserted into the guide groove 120.
