[0024] As Figures 1 to 4 shown, a precast pile structure includes an upper pile body 1 and a lower pile body 2. A positioning component 3 is provided between the upper pile body 1 and the lower pile body 2. At the top of the lower pile body 2, a clamping component 4 for preliminarily connecting the upper pile body 1 is provided. At the top of the lower pile body 2, a locking component 5 for strengthening the limit of the upper pile body 1 is also provided. More specifically, the bottom of the upper pile body 1 is aligned with the bottom of the lower pile body 2. Under the guiding action of the positioning component 3, the upper pile body 1 is inserted into the top of the lower pile body 2. The clamping component 4 is used for preliminarily limiting between the upper pile body 1 and the lower pile body 2, and then the locking component 5 is used for locking the upper pile body 1 and the lower pile body 2 to make them stably connected.

[0025] The alignment component 3 includes a groove 301, and the groove 301 is formed on the top surface of the lower pile body 2. A guiding column 302 is fixedly connected to the inner wall of the groove 301. A jack 303 is formed on the bottom surface of the upper pile body 1, and the guiding column 302 is movably inserted into the jack 303. It should be noted that during the docking process of the upper pile body 1 and the lower pile body 2, the guiding column 302 is aligned with the jack 303, so that the guiding column 302 can finally enter the inner wall of the jack 303, thereby ensuring that the docking angle of the upper pile body 1 and the lower pile body 2 is correct.

[0026] The clamping component 4 includes a mounting box 401, and the mounting box 401 is fixedly connected to the inner wall of the groove 301. A spring 402 is fixedly connected to the inner wall of the mounting box 401. A plug 403 is fixedly connected to the free end of the spring 402, and the plug 403 is movably inserted into the mounting box 401. A connecting seat 404 is fixedly connected to the bottom surface of the upper pile body 1, and the end of the plug 403 is movably inserted into the inner wall of the connecting seat 404. A receiving groove 405 is formed on the top surface of the upper pile body 1, and the specification of the receiving groove 405 is adapted to that of the mounting box 401. More specifically, during the process of the upper pile body 1 being inserted downward into the groove 301, the connecting seat 404 will be driven to descend. When the upper pile body 1 completely enters the groove 301, the mounting box 401 will completely enter the inside of the receiving groove 405, and the connecting seat 404 and the mounting box 401 are aligned. Under the elastic force of the spring 402, the plug 403 will be pushed to insert into the inner wall of the connecting seat 404, so that the plug 403 and the connecting seat 404 cannot be separated, thereby initially limiting the upper pile body 1 and the lower pile body 2.

[0027] The end of the plug 403 is an inclined structure with a narrow upper part and a wide lower part. It should be noted that by setting it as an inclined structure, when the upper pile body 1 drives the connecting seat 404 to move downward, the plug 403 can be squeezed to retract into the inside of the mounting box 401. When the mounting box 401 and the connecting seat 404 are aligned, the plug 403 pops out again under the elastic force of the spring 402 and enters the connecting seat 404, so that the docking of the connecting seat 404 and the plug 403 is more convenient.

[0028] The locking component 5 includes an installation shell 501, and the installation shell 501 is fixedly connected to the upper pile body 1. A double-headed screw rod 502 is rotatably connected to the inner wall of the installation shell 501. Both ends of the double-headed screw rod 502 are threadedly connected with connecting rods 503, and the connecting rods 503 are movably inserted into the installation shell 501. The end of the connecting rod 503 is fixedly connected with an arc-shaped plate 504. A positioning column 505 is fixedly connected to the surface of the arc-shaped plate 504. A positioning hole 506 is formed in the surface of the upper pile body 1, and the inner wall of the positioning hole 506 is movably inserted with the end of the positioning column 505. The locking component 5 further includes an adjusting component for controlling the rotation of the double-headed screw rod 502. More specifically, after docking the upper pile body 1 and the lower pile body 2, the adjusting component is used to control the rotation of the double-headed screw rod 502. Under the action of the thread on its surface, the connecting rod 503 will be driven to move, so as to control the movement of the arc-shaped plate 504. The arc-shaped plate 504 will drive the positioning column 505 to insert into the inner wall of the positioning hole 506, so as to limit the upper pile body 1.

[0029] The adjusting component includes a worm 507, and the worm 507 is rotatably connected to the installation shell 501. A knob 508 is fixedly connected to the front end of the worm 507. A worm gear 509 is fixedly sleeved in the middle of the double-headed screw rod 502, and the worm gear 509 meshes with the worm 507. It should be noted that by rotating the knob 508, the worm 507 is driven to rotate, and the worm 507 will drive the worm gear 509 meshing with it to rotate, so as to control the rotation of the double-headed screw rod 502, and the worm gear 509 and the worm 507 can achieve self-locking, avoiding accidental rotation of the double-headed screw rod 502.

[0030] In summary: Align the bottom of the upper pile body 1 and the bottom of the lower pile body 2. Under the guiding action of the alignment component 3, insert the upper pile body 1 into the top of the lower pile body 2. The clamping component 4 is used to preliminarily limit between the upper pile body 1 and the lower pile body 2, and then the locking component 5 is used to lock the upper pile body 1 and the lower pile body 2, so that the two are stably connected. In use, the effect of facilitating the quick connection and lengthening of the precast pile is achieved, without on-site welding, effectively improving the connection efficiency of the precast pile, and having good practicability.
