Fast connecting device for air impermeability test of water-cooling radiator

Abstract

The invention discloses a fast connecting device for an air impermeability test of a water-cooling radiator. The device comprises a connector and a chuck. The chuck comprises a connecting nut, a star-like limiting plate, a floating locking plate resetting device and a plurality of floating clamping plates. The number of grooves of the star-like limiting plate is equal to that of the floating clamping plates. The protruding part of the star-like limiting plate is connected with the front part of the connecting nut. The middle parts of the floating clamping plates are supported by the lower parts of the grooves of the star-like limiting plate, and the rear ends of the floating clamping plates extend into an inner hole of the connecting nut to form a clamping head of a water pipe head of the radiator. The clamping head is connected with the water pipe head to clamp a step at the end part of the water pipe head. The front end of the connector comprises an outer screw thread in threaded connection with the connecting nut, and the inner hole at the front end of the connector comprises an elastic sealing member of the water pipe head of the radiator. The middle part of the star-like limiting plate comprises a through hole. The fast connecting device for the air impermeability test of the water-cooling radiator provided by the invention is simple in structure, can be quickly connected with a universal water pipe head, and is good in connecting sealing performance, so that the air impermeability test efficiency of the radiator can be improved. The device provided by the invention is suitable for manually testing the air impermeability of the water-cooling radiator.

Description

[technical field] [0001] The invention relates to the air tightness test of a water-cooled radiator, in particular to a quick connection device for the air-tight test of a water-cooled radiator. [Background technique] [0002] In order to ensure the reliability of the product, the air-tightness test must be carried out after the water-cooled radiator is assembled to ensure that the water-cooled radiator can withstand a certain water pressure, so as to avoid water leakage during the working process of the water-cooled radiator and cause safety accidents. [0003] The water-cooled radiator needs two water pipe joints for installing pipelines, and the water pipe joints are also the pipeline connection structure for measuring air tightness. Water pipe joints can be roughly divided into 3 categories. [0004] The first type uses metal materials such as brass and stainless steel, and is machined. One end is milled with pipe threads to cooperate with the radiator, and the other en...

AI Technical Summary

Problems solved by technology

The water pipe and the water pipe joint are interference fit, and it is difficult to squeeze into the water pipe. When clamping the water pipe with a clamp, you need to use a screwdriver to tighten the screws on the clamp. After the test is completed, you need to loosen the clamp, and then pull out the water pipe , very time-consuming

Moreover, the water pipe is easy to be plastically deformed after repeated plugging and unplugging, and the clamp is easy to loosen after being assembled many times.

When testing the air tightness, it may cause air leakage due to poor coordination between the water pipe and the water pipe joint, which may cause misjudgment for the detection of the water-cooled radiator
