[0002] The automobile engine produces a large amount of heat in the running process, which seriously affects the performance, reliability and service life of the engine. As a key component of the cooling system, the rubber pipe of the automobile engine cooling system bears the heavy responsibility of transmitting coolant and plays an indispensable role in maintaining the normal working temperature of the engine. It is responsible for circulating and transmitting the coolant between the engine, radiator, water pump and other components, so that the coolant can absorb the heat generated by the engine and dissipate the heat to the air, thereby helping the engine to maintain at a suitable working temperature and preventing the engine from overheating or overcooling.
[0003] The engine compartment has limited space, and the rubber pipe may be squeezed, rubbed or collided with other components. For example, the jolt during vehicle driving may cause the rubber pipe to rub against the engine or the vehicle frame, which will wear the outer surface of the rubber pipe over time, and in severe cases, it will penetrate the rubber pipe, causing coolant leakage.

The connecting structure comprises a movable connecting plate, which is installed at both ends of the flexible hose. A fixed spring is installed on the outer side of the end of the movable connecting plate close to the flexible hose. One end of the fixed spring is installed with a push ring, and one end of the push ring close to the movable connecting plate is installed with a positioning rod. One end of the positioning rod close to the connecting end head is installed with a circular clamping plate. One end of the connecting end head close to the rubber pipe body is installed with a fixed connecting plate. An annular groove is formed in the inside of the fixed connecting plate, and a plurality of circular sockets are formed in the end of the fixed connecting plate close to the movable connecting plate.
[0007] Preferably, the inner diameter of the flexible hose is greater than the outer diameter of the rubber pipe body, and the movable connecting plate can slide on the outer wall of the rubber pipe body.
[0008] Preferably, one end of the positioning rod penetrates the rubber pipe body, and one end of the positioning rod extends between the fixed connecting plate and the movable connecting plate.
[0009] Preferably, the circular clamping plate matches with the circular socket, and the annular groove communicates with the circular socket.
