[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a prestressed pile connector that is convenient for assembly, including a pile body 1. A connector 2 is provided at the bottom end of the pile body 1. A T-shaped groove 21 is provided inside the connector 2. A clamping block 22 is provided at the bottom of the T-shaped groove 21. An opening groove 3 is provided in the middle of the connector 2. A fixing sleeve 4 is provided on the outer wall of the connector 2. Fixing grooves 5 are provided on both the left and right sides of the upper half of the fixing sleeve 4. An elastic fixing pad 6 is provided in the middle of the fixing sleeve 4. A spring telescopic rod 7 is provided on the left side of the elastic fixing pad 6. The right end of the spring telescopic rod 7 is connected to an inner telescopic rod 8. The pile body 1 is placed into the connector 2 through the T-shaped groove 21, and the pile body 1 is clamped and positioned by the clamping block 22. The fixing sleeve 4 is sleeved on the connector 2. The spring telescopic rod 7 and the inner telescopic rod 8 cooperate with each other to tighten. The elastic fixing pad 6 contracts under pressure, so that the spring telescopic rod 7 and the inner telescopic rod 8 tighten the fixing sleeve 4, thereby completing the fixation of the pile body 1 and the connector 2. The bottom of the connector 2 is connected to a connection head 9. An external thread 10 is provided on the outer wall of the connection head 9. A limiting block 11 is provided at the bottom end of the connection head 9. A fixing block 12 is provided at the bottom end of the limiting block 11. A connecting rod 13 is provided at the bottom end of the fixing block 12. By rotating the connecting rod 13, the connection head 9 is screwed into the threaded hole at the bottom of the connector 2. The limiting block 11 limits the depth of the connection head 9 entering the connector 2, preventing the connection head 9 from entering too much and causing unstable connection of the prestressed pile body, affecting the use stability of the prestressed pile body.

[0022] Among them, a fixed connection seat 71 is provided at the left end of the spring telescopic rod 7. A cavity 72 is provided in the middle of the spring telescopic rod 7. A telescopic spring 73 is connected to the left inner wall of the cavity 72. The right end of the telescopic spring 73 is connected to the inner telescopic rod 8. The telescopic spring 73 is fixedly installed on the left inner wall of the cavity 72. The telescopic spring 73 will expand and contract. The inner telescopic rod 8 moves leftward as the telescopic spring 73 expands and contracts, thereby tightening the connection sleeve 4 and fixing the connector 2 and the pile body 1;

[0023] The clamping block 22 includes a lower mounting plate 221. A pressure column 222 is provided at the top of the lower mounting plate 221. A pressure spring 223 is provided on the outer wall of the pressure column 222. An upper mounting plate 224 is provided at the top end of the pressure column 222. The clamping block 22 is fixed in the T-shaped groove 21 through the lower mounting plate 221. During the placement of the pile body 1, the upper mounting plate 224 is stressed, and the pressure column 222 contracts with the pressure spring 223, facilitating the installation of the pile body 1. When the pile body 1 is disassembled, the pressure spring 223 restores its deformation, causing the upper mounting plate 224 to reset, thereby jacking up the pile body 1 and realizing the rapid disassembly of the pile body 1;

[0024] The opening groove 3 extends from the top of the connecting piece 2 to the bottom of the connecting piece 2, enabling the connecting piece 2 to deform, making it easier to sleeved the fixing sleeve 4 on the connecting piece 2 and fix the connecting piece 2;

[0025] A hole is provided at the bottom of the connecting piece 2, and an inner thread matching the external thread 10 is provided on the inner wall of the hole;

[0026] A clamping groove matching the clamping block 22 is provided in the middle of the bottom of the pile body 1. The pile body 1 is positioned through the clamping block for the clamping groove 22, enabling the pile body 1 to be installed quickly and accurately;

[0027] The left end of the spring telescopic rod 7 and the right end of the inner telescopic rod 8 are both fixedly connected to the surface of the fixing sleeve 4;

[0028] Four groups of fixing grooves 5 are evenly arranged around the outer wall of the fixing sleeve 4, and the depth of the fixing groove 5 is one-third of the height of the fixing sleeve 4.

[0029] Working principle: During installation, the pile body 1 is placed into the interior of the connecting piece 2 through the T-shaped groove 21. The pile body 1 is clamped and positioned through the clamping block 22. The fixing sleeve 4 is sleeved on the connecting piece 2. A clamping groove is provided in the middle of the bottom of the pile body 1, and the pile body 1 is positioned through the clamping block for the clamping groove 22, enabling the pile body 1 to be installed quickly and accurately. The telescopic spring 73 is fixedly installed on the left inner wall of the cavity 72. The telescopic spring 73 will expand and contract. The inner telescopic rod 8 moves leftward as the telescopic spring 73 expands and contracts. The elastic fixing pad 6 contracts under pressure, enabling the spring telescopic rod 7 and the inner telescopic rod 8 to tighten the fixing sleeve 4, thereby completing the fixation of the pile body 1 and the connecting piece 2. Then, the connector 9 is screwed into the threaded hole at the bottom of the connecting piece 2. The limiting block 11 limits the depth of the connector 9 entering the interior of the connecting piece 2, preventing the connector 9 from entering too much and causing unstable connection of the prestressed pile body, affecting the use stability of the prestressed pile body.
