Abstract
The utility model discloses a kind of radiator helium leak test plug.This comprises the overcoat that is provided with blind hole, in the blind hole of overcoat, slidably connect sliding sleeve, between sliding sleeve and overcoat, be provided with spring, sliding sleeve middle part is provided with the bolt being connected with overcoat, sliding sleeve and spring are limited between bolt and overcoat, have the seal ring sealing with overcoat in the arranged outside of sliding sleeve, and one end that sliding sleeve stretches out overcoat is the interface for shutoff water outlet, interface inner side is equipped with seal ring, is hinged with the frame for clamping radiator outlet in the outside of overcoat.Interface is socketed in to the outside of water outlet, seal ring has been filled the gap between interface and water outlet, frame engages with the boss of water outlet, realize the shutoff of water outlet, helium is picked up and is pressed overcoat after end and frame is departed to boss can take off radiator helium leak test plug, has improved the detection efficiency of radiator and the accuracy of detection.
Description
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 plug.
Background technique
Automobile radiators is made up 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, utilizes helium to carry out leakproof detection at the radiator Shi Douhui that dispatches from the factory.Detect time by good the water outlet shutoff of radiator, filling helium in water intake, 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.Prior art mainly adopts plug shaped article body insertion water outlet inside to carry out shutoff, and the not tight testing result that causes of shutoff is inaccurate.
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 plug that can quick blocking radiator outlet is provided, and shutoff is tighter, has improved the detection efficiency of radiator.
For achieving the above object, the technological scheme that the utility model radiator helium leak test plug adopts is:
A kind of radiator helium leak test plug, comprise the overcoat that is provided with blind hole, in the blind hole of overcoat, slidably connect sliding sleeve, between sliding sleeve and overcoat, be provided with spring, sliding sleeve middle part is provided with the bolt being connected with overcoat, sliding sleeve and spring are limited between bolt and overcoat, there is the seal ring sealing with overcoat in the arranged outside of sliding sleeve, one end that sliding sleeve stretches out overcoat is the interface for shutoff water outlet, interface inner side is equipped with seal ring, is hinged with the frame for clamping radiator outlet in the outside of overcoat.Interface is socketed in to the outside of water outlet, seal ring has been filled the gap between interface and water outlet, frame engages with the boss of water outlet, has realized the shutoff of water outlet, and helium is picked up and pressed overcoat after end and frame is departed to boss can take off radiator helium leak test plug.
The other end of sliding sleeve is provided with blind hole, and this blind hole is socketed in the positioning hole of spring outside as spring.Blind hole has ensured that spring is spacing accurately, slides over the interior slip of overcoat smooth and easy.
The front end of described frame is provided with the groove with water outlet clamping.Groove better coordinates with the outer side surface of water outlet, has improved the stability of engaging.
The utility model compared with prior art, has the following advantages:
Interface is socketed in to the outside of water outlet, seal ring has been filled the gap between interface and water outlet, frame engages with the boss of water outlet, realize the shutoff of water outlet, helium is picked up and is pressed overcoat after end and frame is departed to boss can take off radiator helium leak test plug, connection disassembling is rapid, and shutoff good seal performance has improved the detection efficiency of radiator and the accuracy of detection.
Brief description of the drawings
Fig. 1 is radiator helium leak test stopper 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 be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment 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 plug is disclosed, comprise the overcoat 1 that is provided with blind hole 11, in the blind hole 11 of overcoat 1, slidably connect sliding sleeve 2, between sliding sleeve 2 and overcoat 1, be provided with spring 3, sliding sleeve 2 middle parts are inserted with the bolt 4 being connected with overcoat, sliding sleeve and spring are limited between bolt and overcoat, there is the seal ring 5 sealing with overcoat in the arranged outside of sliding sleeve, one end that sliding sleeve stretches out overcoat is the interface 21 for shutoff water outlet, interface inner side is equipped with seal ring 5, the other end of sliding sleeve offers blind hole 22, spring inserts in blind hole 22, be hinged with the frame 6 for clamping radiator outlet in the outside of overcoat, the end of this frame offers the groove 61 with water outlet clamping.
When use, interface is socketed in to the outside of water outlet 10, seal ring has been filled the gap between interface and water outlet, and frame engages with the boss of water outlet, realized the shutoff of water outlet, helium is picked up and is pressed overcoat after end and frame is departed to boss can take off radiator helium leak test plug.
