Specifically, with reference to fig. 4 and 5, the socket part 51 includes a socket column 511, and the socket column 511 is vertically disposed at the center of the inner bottom wall of the hollow pile 3; a clamping slide rail 5111 transversely penetrates through the position, close to the top, of the insertion column 511, and the clamping portion 52 comprises a vertical plate 521, a spring 522 and a clamping block 523; the vertical plate 521 is arranged at the center position in the clamping slide rail 5111, the springs 522 are respectively arranged on two plate surfaces of the vertical plate 521, and the clamping blocks 523 are arranged at one ends of the springs 522 far away from the vertical plate 521; a sliding blocking part 9 is arranged at an opening of the clamping slide way 5111 on the inserting column 511, and the sliding blocking part 9 is used for preventing the clamping block 523 from sliding out of the clamping slide way 5111; the sliding blocking part 9 is automatically separated from the opening of the clamping slide rail 5111 after the insertion column 511 is inserted into the insertion groove 63, and part of the clamping block 523 moves into the clamping groove 62 when the opening end of the clamping slide rail 5111 is opposite to the clamping groove 62.
When the plug-in post 511 is inserted into the plug-in groove 63 and the open end of the clamping slideway 5111 is aligned with the clamping groove 62, the sliding blocking part 9 is separated from the opening of the clamping slideway 5111, at this time, the sliding blocking part 9 no longer blocks the clamping block 523, under the elastic action of the spring 522, the clamping block 523 can move from the clamping slideway 5111 to the clamping groove 62, and finally, a part of the clamping block 523 is in the clamping groove 62 and a part of the clamping block 523 is left in the clamping slideway 5111; solid pile 6 can be locked at the current position this moment to solid pile 6 becomes non-detachable state with being connected of hollow pile 3, not only reaches the effect that lets solid pile 6 get into hollow pile 3 interior back automatic positioning, improves solid pile 6 moreover and enters into hollow pile 3 interior back two's connection effect.
With reference to fig. 4 and 5, the slide blocking portion 9 includes a blocking plate 91 and a slider 92, the slider 92 being disposed on the blocking plate 91; a sliding groove 5112 is formed in the side wall of the plug column 511 along the length direction of the plug column 511, and the blocking plate 91 is in sliding fit with the sliding groove 5112 through a sliding block 92; the width of the inserting groove 63 is consistent with that of the inserting column 511, an accommodating groove 34 is formed in the inner bottom wall of the hollow pile 3, and the accommodating groove 34 is used for the blocking plate 91 to slide in; when the blocking plate 91 normally blocks the port of the clamping slideway 5111, the spring 522 drives the clamping block 523 to abut against the surface of the blocking plate 91, and the elasticity of the spring 522 is greater than the gravity of the blocking plate 91 and the slider 92.
When the solid pile 6 moves downwards vertically, the edge of the solid pile 6 positioned in the insertion groove 63 abuts against the blocking plate 91 because the width of the insertion groove 63 is consistent with that of the insertion column 511; after the solid pile 6 continues to move downwards, the edge part of the solid pile 6, which is positioned in the insertion groove 63, can continuously abut against the blocking plate 91 to move downwards, so that the sliding block 92 drives the blocking plate 91 to move downwards vertically; since the spring 522 abuts the clamping block 523 against the surface of the blocking plate 91, the blocking plate 91 cannot move by itself and is always located at the opening position of the clamping slideway 5111, that is, the blocking plate 91 located at the opening position of the clamping slideway 5111 is maintained by the abutting force of the clamping block 523 against the surface of the blocking plate 91; however, when the edge portion of the solid pile 6 located in the inserting groove 63 moves vertically downward, the blocking plate 91 is actively pushed downward, until the blocking plate 91 is completely separated from the abutting of the clamping block 523, the blocking plate 91 directly slides downward under the action of gravity, and finally slides into the accommodating groove 34, so that the effects of automatic blocking and automatic separation of the blocking plate 91 are achieved.
