Detailed Implementation

[0022] In the following description, embodiments of the concrete inspection well casting bottom formwork fixing device of the present invention will be described with reference to the accompanying drawings.

[0023] Figures 1-4 This invention illustrates a concrete inspection well casting bottom formwork fixing device according to an embodiment of the present invention. It includes multiple fixing ears 2 fixedly connected to the bottom surface of an outer mold 1. A tightening shell 3 is rotatably connected to the surface of each fixing ear 2. A handle 10 is fixedly connected to the side of the tightening shell 3 away from the fixing ears 2. Two second torsion springs 6 are sleeved on the surface of each fixing ear 2. One end of each second torsion spring 6 is welded to the fixing ear 2, and the other end is welded to the tightening shell 3. A bottom mold 11 is provided at the bottom of the outer mold 1, and a locking assembly is provided in the inner cavity of the tightening shell 3. Component 4, the locking assembly 4 includes a locking hook 41 located inside the tightening shell 3. A limiting seat 8 is fixedly connected to the inner cavity of the tightening shell 3. A rectangular limiting groove 9, adapted to the limiting seat 8, is formed on the surface of the locking hook 41. Through the cooperation of the limiting seat 8 and the rectangular limiting groove 9, the locking hook 41 is limited and guided, thereby improving its stability during sliding. Multiple locking pins 42, adapted to the locking hook 41, are fixedly connected to the surface of the bottom mold 11. A rotating column 43 is rotatably connected to the inner cavity of the tightening shell 3. A gear 44 is fixedly connected to the surface of the column 43. A rack 45 is fixedly connected to one side of the locking hook 41. The rack 45 and the gear 44 mesh with each other. A backstop assembly 5 is provided on one side of the tightening shell 3. The backstop assembly 5 includes a ratchet disc 51. One end of the rotating column 43 away from the ratchet disc 51 extends through to the outside of the tightening shell 3 and is fixedly connected to a rocker disc 7. Another end of the rotating column 43 extends through to the outside of the tightening shell 3 and is fixedly connected to the ratchet disc 51. A fixing pin 52 is fixedly connected to one side of the tightening shell 3. A first torsion spring is sleeved on the surface of the fixing pin 52. 54. One end of the first torsion spring 54 is welded to the tightening shell 3, and the other end of the first torsion spring 54 is welded to the anti-reverse clamp 53. Through the setting of the first torsion spring 54, the anti-reverse clamp 53 plays an elastic torsion role, so that the anti-reverse clamp 53 can actively engage with the surface of the ratchet 51, thereby preventing the ratchet 51 and the rotating column 43 from rotating on their own, thereby improving the connection stability of the outer mold 1 and the bottom mold 11. The surface of the fixing pin 52 is rotatably connected to the anti-reverse clamp 53, and the anti-reverse clamp 53 engages with the ratchet 51.

[0024] Working principle: When using this utility model, the user hangs the outer mold 1 on top of the bottom mold 11, then holds the handle 10 with one hand and pushes the tightening shell 3, causing the tightening shell 3 to rotate around its connection point with the fixing ear 2. This causes the locking hook 41 to reach below the locking pin 42, simultaneously causing the second torsion spring 6 to twist. The user then shakes the rocker 7, which in turn drives the rotating column 43 to rotate. The rotating column 43, in turn, drives the gear 44 to rotate. The gear 44, during its rotation... During the process, the rack 45 that meshes with it slides upward, thereby causing the locking hook 41 to rise upward and stably engage with the surface of the locking pin 42. As the rotating column 43 rotates, it drives the ratchet 51 to rotate. During the rotation of the ratchet 51, the ratchet 51 causes the anti-reverse clamp 53 to be pushed. At the same time, under the elastic torsion action of the first torsion spring 54, the anti-reverse clamp 53 actively engages with the surface of the ratchet 51, thereby preventing the rotating column 43 and the gear 44 from rotating on their own, thus improving the connection stability of the locking hook 41 and the locking pin 42.

[0025] In summary, this concrete inspection well casting bottom formwork fixing device, through the combined use of fixing ear 2, tightening shell 3 and locking component 4, connects and fixes the outer mold 1 and bottom mold 11. At the same time, with the cooperation of anti-reverse component 5, the locking position and force are strengthened, thus achieving the purpose of stable and reliable connection and easy disassembly and assembly.
