Description

Rotational locking mechanism of limo sewage system Technical Field The utility model relates to the technical field of sealing and locking devices of fluid conveying systems, in particular to a rotary locking mechanism of a limo sewage system. Background The clamping structure of the conventional limousine sewage disposal system has the problems of poor tightness, insufficient connection stability, complex operation and the like. Traditional buckle formula quick connector relies on elasticity jack catch and annular groove cooperation, but lacks angle compensation mechanism, and the pipeline produces the skew easily to lead to the leakage rate high, and long-term vibrations lead to the jack catch plastic deformation. The threaded connection scheme can realize sealing, but local stress concentration is easy to be caused by uneven bolt torque, the sealing failure rate is high, and the threaded connection scheme cannot adapt to extreme environments. Therefore, a clamping structure with high sealing performance, vibration offset resistance and quick disassembly and assembly capability is needed to solve the reliability bottleneck of the motor home sewage disposal system under the complex working condition.
