Description

A kind of safe leakage detection apparatus that prevents unexpected ejection

Technical field

The utility model relates to heating radiator production field, especially relates to a kind of unexpected safe leakage detection apparatus ejecting that prevents.

Background technology

Heating radiator is the critical component of automobile cooling system.Heating radiator is mainly made up of radiator centre, left and right plastic water chamber and rubber gasket, and its core is radiator centre.Radiator centre is made up of main leaf, side plate, radiating tube and heat-radiation belt, by soldering tech, aluminium is welded together, then connects radiator centre and hydroecium by the mode of mechanical undercut, reaches the effect of sealing by compressing rubber sealing gasket.In actual production process, in order to detect the sealing property of each heating radiator, all need to do leak detection test.Current leakage detection apparatus often there will be the phenomenon of ejection in leak detection test, and the main cause that causes this phenomenon to occur comprises that the distortion of the hydroecium mouth of pipe, hydroecium mouth of pipe size differ, hydroecium internal gas pressure is excessive and verifying attachment ring wear etc.Verifying attachment ejects bring very harmful because verifying attachment is iron piece, device while being ejected by air pressure dynamics very large, gently damage product and equipment, heavy pound with it operator, cause the damage of personnel and equipment.

Utility model content

The purpose of this utility model is exactly to provide a kind of unexpected safe leakage detection apparatus ejecting that prevents in order to overcome the defect that above-mentioned prior art exists.

The purpose of this utility model can be achieved through the following technical solutions: a kind of safe leakage detection apparatus that prevents unexpected ejection, for checking the sealing of radiator water chamber, it is characterized in that, comprise vexed bar, spanner, stop collar, lower lock block, spring, claw and seal head, described lower lock block is positioned in stop collar, in the middle of lower lock block, be provided with spring groove, described spring is placed in spring groove, and between stop collar and lower lock block, described claw is positioned in stop collar, claw sidewall is provided with the grab that end extends internally, the lower surface of this grab is against on lower lock block, claw front end is provided with buckle, the raised brim of buckle and the hydroecium mouth of pipe is suitable, described seal head is positioned in claw and props up the upper surface of grab, described vexed bar inserts from stop collar bottom, successively through stop collar, spring, lower lock block, fixing after claw and seal head, described spanner is fixed on vexed bar, its front end props up stop collar,

When leak detection, first seal head is filled in to the hydroecium mouth of pipe, then pressed down spanner, stop collar is pressing spring under spanner effect, and spring makes lower lock block press down grab, and then presses down seal head and block the hydroecium mouth of pipe; Meanwhile, claw encases the hydroecium mouth of pipe outward, and buckle and the fastening of hydroecium mouth of pipe raised brim, make leakage detection apparatus closely be connected with hydroecium, is difficult for being ejected when leak detection.

Described seal head comprises upper holder block, caulking gum and packing ring, described upper holder block, caulking gum and packing ring is fixedly connected with through after vexed bar successively, described upper holder block is positioned in claw and props up the upper surface of grab, grab presses down upper holder block, and then press seal rubber, the sealing orifice thereby caulking gum expands.

The outer ring of described upper holder block is provided with annular groove, in this annular groove, is provided with O-ring seal.

Described stop collar bottom is provided with outwards outstanding hollow joint, and described joint is provided with external thread, and described external thread is combined with setting nut, and described vexed bar inserts in joint, fixes with setting nut, and described spanner front end props up setting nut.

Compared with prior art, the utility model is by increasing safe block button, in the time that leakage detection apparatus compresses, buckle blocks the raised brim of the hydroecium mouth of pipe firmly, make leakage detection apparatus can be because of pressure the excessive or factors such as hydroecium mouth of pipe size distortion, variation and cause leakage detection apparatus surprisingly to eject, not only improve the safety coefficient of leak detection, and then improved the efficiency of leak detection operation, also there is simple in structure, easy operating and low cost and other advantages.
