Embodiment Construction
[0014] Now in conjunction with accompanying drawing, describe concrete structure of the present invention, as figure 1 As shown, 1a and 1b are two sections of corrugated pipes to be connected. After the connecting ports are polished and smoothed, they are respectively inserted from both ends of the sealing hose 1, and are butted 1d at the radial centerline of the sealing hose, and then fixed Place the pipe clamp 2 outside the sealed hose, and ensure that its axial center line is located at the butt joint 1d of the bellows. Use the bolt 2e to pass through the screw hole 2b and the corresponding screw hole, and lock it with the nut locking screw 2f. The crest 2a inside the fixed pipe clamp and the trough 1c on the outer wall of the bellows are engaged with each other, and the sealing hose 1 is tightened to achieve the purpose of sealing.

The invention relates to a corrugated pipe connecting component which comprises a section of sealing hose pipe and a pair of arch-shaped fixed pipe clamps, wherein the sealing hose pipe is made of rubber-plastic sponge or plastics, and a corrugated pipe to be connected can pass through the sealing hose pipe; the fixed pipe clamps are made of plastics or glass fiber reinforced plastics; the inner wall of each fixed pipe clamp is provided with corrugation which is matched with the corrugation on the outer wall of the corrugated pipe to be connected; outer edge bodies are respectively arranged at the two sides along the radial direction of each fixed pipe clamp; the outer edge body arranged at each side is provided with a screw hole, and a nut locking screw can be locked by the screw hole; two inner flangings are respectively arranged at the two ends along the axial direction of each fixed pipe clamp, and are used for fixing the pipe clamps and the corrugated pipe. The corrugated pipe connecting component is simple in structure, convenient to operate, good in sealing performance and lower in cost; furthermore, the corrugated pipe connecting component is excellent in corrosion resistance and high in practicality.
Description
technical field [0001] The invention relates to a pipe connection assembly, in particular to a corrugated pipe connection assembly. Background technique [0002] In recent years, my country's large-diameter corrugated pipes have developed rapidly. The common materials are PE and PVC. The structure is divided into double-wall corrugated pipes, winding structure wall pipes, etc. These pipes are characterized by their unique high rigidity, corrosion resistance, etc. Advantages It is widely used in the fields of buried drainage, sewage and tap water transportation. The traditional connection method between the pipes is: Put a rubber sealing ring on the trough of one end of the bellows tail (straight pipe without flare), insert it into the official road with flare at the other end, and then tighten it with a lead wire to prevent leakage. To the connection function of sealing anti-loosening. There are many defects in this connection method. Leakage is often caused by the corrosio...
