Description

A kind of radiator helium leak test joint
Technical field
The utility model relates to a kind of cubing for detection of radiator, especially relates to a kind of radiator helium leak test joint.
Background technique
Automobile radiators consists of three parts such as intake chamber, water-supplying chamber, main leaf and radiator cores, and inside is filled with cooling liquid, for the radiator after preventing from installing leaks, at the radiator Shi Douhui that dispatches from the factory, utilizes helium to carry out leakproof detection.When detecting, the water outlet shutoff of radiator is good, in water intake, filling helium, after pressurize a period of time, look at whether manometric registration declines, if declined, show radiator gas leakage, if registration does not change, show that radiator is good seal.The pneumatic tube of helium is cumbersome with being connected of water intake, and the connect hours is long, has reduced detection efficiency.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, and a kind of radiator helium leak test joint that can connect fast helium pneumatic tube and water inlet of radiator is provided, and has improved the detection efficiency of radiator.
For achieving the above object, the technological scheme that the utility model radiator helium leak test joint adopts is:
A kind of radiator helium leak test joint, the overcoat that comprises hollow, overcoat inside is provided with step, in overcoat inside, slidably connect sliding sleeve, between sliding sleeve and step, be provided with spring, sliding sleeve center is provided with the hollow bolt being connected with overcoat, the axial hole of hollow bolt communicates with the hole of the hollow of overcoat, arranged outside at sliding sleeve has the seal ring sealing with overcoat, one end that sliding sleeve stretches out overcoat is outlet side, inner side, outlet side is equipped with seal ring, overcoat is provided with the inlet end being connected with helium pipeline, outlet side is for connecting the water intake of radiator, the outside of overcoat is hinged with the frame for clamping water intake.The inlet end of overcoat is fixedly connected with helium pipeline, dock with water intake the outlet side of sliding sleeve, slip sliding sleeve rotates frame to the boss limit of water intake and engages with boss, under the rebounding force effect of spring, outlet side and water intake are fastened togather firmly, after detection finishes, push sliding sleeve rotation frame and can take off radiator helium leak test joint, accelerate connection speed and dismounting speed, improved the detection efficiency of radiator.
One end that sliding sleeve inserts overcoat is provided with blind hole, and blind hole is socketed in spring, and spring housing is connected on the outside of hollow bolt.Guaranteed that spring is spacing accurately, slided over the interior slip of overcoat smooth and easy.
The front end of frame is provided with the groove with water intake clamping.Groove better coordinates with the outer side surface of water intake, has improved the stability of engaging.
The utility model compared with prior art, has the following advantages:
The inlet end of overcoat is fixedly connected with carrying the pipeline of helium, the outlet side of sliding sleeve is socketed in to water inlet, rotation frame is connected on the boss of water intake, after detection finishes, extruding sliding sleeve rotation frame can take off radiator helium leak test joint, accelerate connection speed and dismounting speed, improved the detection efficiency of radiator.
Accompanying drawing explanation
Fig. 1 is radiator helium leak test joint structure schematic diagram.
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these mode of executions and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As depicted in figs. 1 and 2, a kind of radiator helium leak test joint is disclosed, the overcoat 1 that comprises hollow, overcoat inside offers step 11, in overcoat inside, slidably connect sliding sleeve 2, the inner side, one end that sliding sleeve stretches out overcoat is provided with seal ring 5 for outlet side 21, the other end of sliding sleeve is provided with blind hole 22, in blind hole, insert spring 3, this spring is between sliding sleeve and the step of overcoat, in the inside of sliding sleeve, be provided with hollow bolt 4, this hollow bolt is connected with overcoat sliding sleeve and spring is limited in overcoat, the through hole 41 of hollow bolt communicates with the hole 13 of overcoat hollow, the other end of overcoat is provided with the inlet end 12 being connected with helium pipeline, in the outside of sliding sleeve, be socketed with the seal ring 5 of twice and overcoat sealing, seal ring is socketed in the groove of sliding sleeve outer side surface, in the outside of overcoat, be hinged with the frame 6 for clamping water intake, the front end of frame is provided with the groove 61 with water intake clamping.Outlet side is connected with the water intake 10 of radiator, and the inlet end of overcoat is fixedly connected with helium pipeline 20.Dock with water intake the outlet side of sliding sleeve, slip sliding sleeve rotates frame to the boss limit of water intake and engages with boss, under the rebounding force effect of spring, outlet side and water intake are fastened togather firmly, after detection finishes, push sliding sleeve rotation frame and can take off radiator helium leak test joint, accelerate connection speed and dismounting speed, improved the detection efficiency of radiator.
