[0002] Cement culverts are tubular structures made of materials such as cement and steel bars. They are mainly used for drainage, water passage, and culvert construction in various infrastructure projects. They are used to guide rainwater, groundwater, and other water flows, ensuring the stability of the roadbed. They can also be used as water pipelines to transport water to different areas for irrigation. Cement culverts are also widely used in urban drainage networks to collect and discharge domestic sewage and rainwater.

[0003] During the installation and disassembly of cement culvert external molds, the mold position needs to be adjusted multiple times to ensure accurate mold closing. At the same time, multiple bolts are used for fixing, making the mold closing and demolding process cumbersome and time-consuming, which reduces production efficiency. Therefore, there is a need to provide a cement culvert external mold that can be quickly assembled and disassembled. By using a method of pre-locking and then tightening the lock, the two molds can be accurately and reliably fixed, improving assembly and disassembly efficiency as well as growth efficiency.

[0022] In the following description, embodiments of the quick-assembly and disassembly external mold for cement culverts of this invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a quick-assembly and disassembly outer mold for a cement culvert, comprising a first mold 1; a second mold 2 is disposed on the right side of the first mold 1; a rotating component 4 is disposed on the rear side of the first mold 1 and the second mold 2, with both ends of the rotating component 4 welded to the first mold 1 and the second mold 2 respectively; lifting lugs 8 are welded to the top and bottom of the opposite sides of the first mold 1 and the second mold 2; a pre-locking assembly 3 is disposed on the front side of the first mold 1 and the second mold 2; the pre-locking assembly 3 includes a fixed rod 31 fixedly connected to the front side of the first mold 1; and a slidable rotating rod 32 is disposed on the front side of the second mold 2; spring steel plates 35 are welded to the top and bottom of the right side of the rotating rod 32; the rear side of the spring steel plate 35 is in close contact with the surface of the second mold 2; the spring steel plate 35 provides elastic pushing for the rotating rod 32, allowing the rotating rod 32 to rotate actively and causing the locking hook 34 to quickly engage with the surface of the fixed rod 31, thus completing the pre-locking of the front side of the first mold 1 and the second mold 2. The lock, the second mold 2, has an arc-shaped groove 33 on its top that matches the rotating rod 32. Multiple locking hooks 34 are fixedly connected to the surface of the rotating rod 32, and multiple anti-detachment plates 7 are fixedly connected to the surface of the fixed rod 31. The locking hooks 34 are located between two adjacent anti-detachment plates 7. The anti-detachment plates 7 limit the locking hooks 34, ensuring they are stably engaged with the surface of the fixed rod 31, thus preventing slippage and improving the locking hooks' stability. The stability of the connection of the fixed rod 31 is ensured by the locking hook 34 engaging with the surface of the fixed rod 31. A fixed seat 5 is welded to the front side of the second mold 2. A locking assembly 6 is provided in the inner cavity of the fixed seat 5. The locking assembly 6 includes a connecting plate 61 welded to the surface of the rotating rod 32. A screw 62 is welded to the right side of the connecting plate 61. A rectangular groove 63 adapted to the screw 62 is provided on the right side of the fixed seat 5. The left side of the threaded sleeve 64 is in close contact with the surface of the fixed seat 5. The threaded sleeve 64 is threadedly connected to the surface of the screw 62.

[0024] Working principle: When using this invention, the user rotates the second mold 2, causing the front ends of the first mold 1 and the second mold 2 to contact each other. At this time, the locking hook 34 rotates due to the obstruction of the fixing rod 31, and simultaneously causes the spring steel sheet 35 to be compressed and deformed. Until the front sides of the first mold 1 and the second mold 2 are completely in contact, under the elastic compression of the spring steel sheet 35, the locking hook 34 is completely locked onto the surface of the fixing rod 31, and the screw 62 is locked into the inner cavity of the rectangular slide groove 63. Then, the connecting plate 61 is sleeved on the surface of the screw 62, and the connecting plate 61 is rotated, causing the connecting plate 61 to be threaded and pushed onto the surface of the screw 62. This generates a reverse force on the screw 62, pulling the screw 62 and the connecting plate 61, thereby causing the locking hook 34 to tightly engage with the surface of the fixing rod 31, completely locking the front sides of the first mold 1 and the second mold 2. At this point, the mold closing is completed. During disassembly, the user rotates the connecting plate 61 to release the limit on the screw 62, and rotates the screw 62, causing the rotating rod 32 and the locking hook 34 to rotate, thereby causing the locking hook 34 to disengage from the surface of the fixing rod 31. At this point, the first mold 1 and the second mold 2 are disengaged. Rotating the first mold 1 or the second mold 2 can separate the first mold 1 and the second mold 2 to complete the demolding.

[0025] In summary, this quick-assembly and disassembly cement culvert outer mold, through the setting of the pre-locking component 3, pre-locks and fixes the first mold 1 and the second mold 2. Then, through the cooperation of the fixing seat 5 and the locking component 6, the front sides of the first mold 1 and the second mold 2 are tightened and locked, thus achieving the purpose of stable and reliable mold closing and easy and quick assembly and disassembly.
