Description

Technical Field

[0001] The utility model relates to the field of water pipe joints, in particular to an engine water pipe joint with a long service life. Background Art

[0002] As we all know, engine water pipe joints are generally joints that connect water pipes in the cooling system. These joints help connect components such as water supply pipes, water return pipes, and temperature sensors so that the refrigerant can flow and circulate effectively. These joints are usually located on the top or side of the engine, depending on the design of the engine.

[0003] The existing engine water pipe joint has a simple structure and lacks a shock-absorbing structure when in use. When the engine water pipe joint vibrates too much, fatigue cracks will occur at the joint and eventually break, causing the cooling system to fail and damage the engine. Utility Model Content

In this structure, the base 7 is fixed to the specified position of the engine compartment by bolts, and the two ends of the water pipe joint body 1 are respectively connected to the engine water pipe and the radiator water pipe through conduits. When the car is vibrating, the buffer seat 5 will continuously compress the spring 11, so that the damping rod 8 will reciprocate and rise and fall. During the lifting process, the damping rod 8 will cause the limit block 9 to rub the damping sleeve 10, thereby providing a damping effect to the water pipe joint body 1 during the shock absorption process, and can make the water pipe joint body 1 quickly stabilized. Through the provided limit seat 13, the bottom end of the buffer rod 12 can be limited to prevent the bottom end of the buffer rod 12 from being pulled out at the four corners of the fixed seat 6, thereby improving the service life of the water pipe joint body 1.
