Description
Technical field
The present invention relates to heating radiator production field, especially relate to a kind of safe leakage detection apparatus preventing unexpected ejection.
Background technology
Heating radiator is the critical component of automobile cooling system.Heating radiator is primarily of radiator centre, left and right plastic water chamber and rubber gasket composition, and its core is radiator centre.Radiator centre is made up of main leaf, side plate, radiating tube and heat-radiation belt, is welded together by aluminium by soldering tech, then connects radiator centre and hydroecium by the mode of mechanical undercut, is reached the effect of sealing by compressing rubber sealing gasket.In order to detect the sealing property of each heating radiator in actual production process, 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 causing this phenomenon to occur comprises hydroecium nozzle distortion, hydroecium nozzle sizes differs, hydroecium internal gas pressure is excessive and verifying attachment ring wear etc.Verifying attachment ejects bring very harmful, because verifying attachment is iron piece, when device is ejected by air pressure, dynamics is very large, gently then damage product and equipment, heavy then pound with it operator, causes the damage of personnel and equipment.
Summary of the invention
Object of the present invention is exactly provide a kind of to overcome defect that above-mentioned prior art exists to prevent the unexpected safe leakage detection apparatus ejected.
Object of the present invention can be achieved through the following technical solutions: a kind of safe leakage detection apparatus preventing 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, spring groove is provided with in the middle of lower lock block, described spring is placed in spring groove, and be 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 to be positioned in claw and to prop up the upper surface of grab, described vexed bar inserts bottom stop collar, successively through stop collar, spring, lower lock block, fix after claw and seal head, described spanner is fixed on vexed bar, its front end props up stop collar,
During leak detection, first seal head is filled in the hydroecium mouth of pipe, then press 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, encase the hydroecium mouth of pipe outside claw, buckle and the fastening of hydroecium mouth of pipe raised brim, make leakage detection apparatus and hydroecium compact siro spinning technology, be not easily ejected during leak detection.
Described seal head comprises upper holder block, caulking gum and packing ring, described upper holder block, caulking gum and packing ring are fixedly connected with through after vexed bar successively, described upper holder block to be positioned in claw and to prop up the upper surface of grab, grab presses down upper holder block, and then press seal rubber, caulking gum expands thus sealing orifice.
The outer ring of described upper holder block is provided with annular groove, is provided with O-ring seal in this annular groove.
Be provided with hollow joint outwardly bottom described stop collar, described joint is provided with external thread, and described external thread is combined with setting nut, and described vexed bar inserts in joint, and fix with setting nut, described spanner front end props up setting nut.
Compared with prior art, the present invention is by increasing safe block button, when leakage detection apparatus compresses, buckle blocks the raised brim of the hydroecium mouth of pipe firmly, make leakage detection apparatus can not because of pressure the excessive or factors such as the distortion of hydroecium nozzle sizes, change and cause leakage detection apparatus surprisingly to eject, not only increase the safety coefficient of leak detection, and then improve the efficiency of leak detection operation, also have structure simple, be easy to operation and low cost and other advantages.
