AI Technical Summary
When testing the airtightness of pipe fittings for existing cold plate heat exchangers, the bamboo-joint type water taps are too thin and costly, resulting in unsatisfactory test results.
A novel helium leak test fixture for end face and inner diameter sealing is designed. It adopts a double-layer T-shaped sealing ring and a multi-layer O-ring sealing ring structure. The fixture is used to fix and seal the water nozzle through clamps and snap-fit seats to conduct air tightness tests.
It achieves efficient airtightness testing, avoids faucet deformation and poor appearance, and improves the reliability of test results.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to pipeline fitting joint leakproofness detection technical field, concretely to a novel end face and internal diameter sealed helium detection clamp. BACKGROUND
[0002] New energy automobile liquid cooling plate must need to detect whether leakage and sealing grade before delivery, the structure of traditional stamping type cold plate, when 200KPa detection of inflation pressure after welding is qualified, will not happen deformation, and will not cause appearance bad because of air tightness detection;
[0003] In the prior art, the pipeline fitting joint of the cold plate heat exchanger, when air tightness testing, bamboo joint type water nozzle is too thin, the cost is relatively high, and the detection result is not ideal. UTILITY MODEL CONTENT
[0004] The utility model discloses a novel end face and internal diameter sealed helium detection clamp to solve the problems in the above background.
[0005] To achieve the above object, the utility model provides the following technical scheme: a novel end face and internal diameter sealed helium detection clamp, including the jar body, the jar body both sides symmetry is equipped with with connecting clamp tongs, the jar body lower part is equipped with with connecting the clamping seat, and the other end of the clamping seat away from the jar body is equipped with with the jar body connection's positioning plug.
[0006] Further optimization, the clamp tongs lower part with the clamping seat are connected through jar body bolt activity.
[0007] Further optimization, the clamp tongs bottom is equipped with with the positioning plug corresponding clamping groove.
[0008] Further optimization, the clamp tongs with the jar body between being equipped with the spring of connection.
[0009] Further optimization, the first O type sealing ring and gasket positioning block are sequentially equipped in the jar body inner chamber.
[0010] Further optimization, the second O type sealing ring, the third O type sealing ring and the fourth O type sealing ring are sequentially equipped in the jar body lower end.
[0011] Further optimization, the first sealing ring gasket and the second sealing ring gasket are respectively equipped between the second O type sealing ring, the third O type sealing ring and the fourth O type sealing ring.
[0012] Beneficial effect
[0013] The novel end face and inner diameter sealing helium detection clamp provided by the utility model, artificial presses down the clamp to open the bayonet, inserts the product water nozzle through the inner positioning plug, gently presses down, loosens the clamp, clamps the water nozzle, takes in air from the air inlet, the middle double-layer T-shaped sealing ring effectively airproofs, the end face sealing ring O ring covers the water nozzle to realize double insurance, starts to test the air tightness, replaces the single model of the dust cap in the prior art, and the single operation disadvantage is replaced, and the detection result is excellent. BRIEF DESCRIPTION OF DRAWINGS
