Detailed Implementation

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-3 A prefabricated basement retaining wall connection device includes two retaining wall bodies 20, which are fitted together. Symmetrically distributed connecting blocks 2 and fixing blocks 3 are welded to one side of each retaining wall body 20 at the top and bottom positions. A fixing post 11 is welded to one side of the connecting block 2. An insertion port is provided on the side of the fixing block 3 near the connecting block 2, and the fixing post 11 is inserted into the insertion port. A slot 17 is provided at the top of the fixing post 11. A sliding groove is provided inside the connecting block 2, and a locking block 10 is slidably connected within the sliding groove and engages with the slot 17. A first spring 9 is provided within the sliding groove, and both ends of the first spring 9 are fixed to the locking block 10 and the fixing block 3 respectively. The top of the locking block 10 is connected via... The bearing is rotatably connected to a connecting column 6, and the connecting column 6 extends through the first spring 9 to form a fixing block 3. The top of the fixing block 3 is provided with a locking assembly for fixing the locking block 10. When disassembly is required, the locking block 10 is pulled upward by the connecting column 6, and the locking block 10 will squeeze the first spring 9, thereby disengaging the locking block 10 from the locking block 10 on the fixing column 11. At this time, the two retaining walls can be separated, which facilitates the disassembly and maintenance of the retaining walls, saves time, and improves the efficiency of retaining wall disassembly. Since the locking block 10 squeezes the first spring 9 when it moves upward, the locking block 10 can be automatically reset by the force of the first spring 9, thus realizing the automatic reset of the locking block 10.

[0024] In this utility model, the engaging assembly includes an elliptical groove 13, which is formed on the top of the fixing block 3. The connecting post 6 passes through the elliptical groove 13. A circular groove 12 is formed at the bottom of the elliptical groove 13. An elliptical block 7 is welded to the outside of the connecting post 6, and the elliptical block 7 engages with the circular groove 12. A knob 5 for rotating the connecting post 6 is welded to the top of the connecting post 6. The top of the fixing block 3 is provided with an insertion assembly for fixing the connecting post 6. The insertion assembly includes a fixing plate 19. 9 is welded to the top of the fixing block 3. A through hole is opened on one side of the fixing plate 19, and a plug rod is slidably connected in the through hole. Multiple equally spaced insertion holes 18 are opened on the outside of the knob 5, and the plug rod is inserted into the insertion holes 18. A slider 16 is welded to one end of the plug rod, and a second spring 14 is sleeved on the outside of the plug rod. The two ends of the second spring 14 are fixed to the fixing plate 19 and the slider 16 respectively. The top of the slider 16 is fixed with a sliding column 15 for pulling the slider 16 to move by bolts. Pulling the slider 16 moves the insertion rod, which in turn moves the second spring 14, causing the insertion rod to disengage from the insertion hole 18 on the knob 5. At this point, the connecting post 6 can be rotated by the knob 5, which in turn rotates the elliptical block 7. After the elliptical block 7 is rotated to align with the elliptical groove 13, it is easy to pull the connecting post 6 upward. During the movement, the slider 16 stretches the second spring 14, so the slider 16 can automatically reset under the force of the second spring 14. A rubber ball 8 is attached to one end of the fixing post 11. The curved surface of the rubber ball 8 facilitates the insertion of the fixing post 11 into the insertion hole. A groove 4 is provided on one side of the retaining wall body 20, and a protrusion 1 is integrally formed on the other side of the retaining wall body 20. When connecting the two retaining wall bodies 20, the protrusion 1 on one retaining wall is inserted into the groove 4 on the other retaining wall, thereby positioning and connecting the two retaining walls. This makes it easier for workers to position and connect the retaining walls and improves the convenience of connecting the retaining walls.

[0025] Working principle: When disassembly is required, the slider 16 is first moved by the sliding column 15. The slider 16 will drive the insertion rod to move and stretch the second spring 14, so that the insertion rod is disengaged from the insertion hole 18 on the knob 5. At this time, the connecting column 6 can be rotated by the knob 5. The connecting column 6 will drive the elliptical block 7 to rotate. After the elliptical block 7 is rotated to align with the elliptical groove 13, it is easy to pull the connecting column 6 upward. The connecting column 6 will drive the locking block 10 to move upward and squeeze the first spring 9, so that the locking block 10 is disengaged from the locking block 10 on the fixed column 11. At this time, the two retaining walls can be separated, which is convenient for disassembly and maintenance of the retaining walls, saves time and improves the efficiency of retaining wall disassembly.
