Description
Technical field
The present invention relates to radiator production field, the unexpected safe leakage detection apparatus for ejecting are prevented more particularly, to a kind of.
Background technology
Radiator is the critical component of automobile cooling system.Radiator it is main by radiator centre, left and right plastic water chamber and
Rubber gasket is constituted, and its core is radiator centre.Radiator centre is made up of main leaf, side plate, radiating tube and heat-radiation belt, leads to
Cross soldering tech to weld together aluminium, then radiator centre and hydroecium are connected by way of mechanical undercut, by compression
Rubber gasket reaches the effect of sealing.In order to detect each sealing property of radiator in actual production process, all need
Do leak detection test.Current leakage detection apparatus often occur the phenomenon of ejection in test of hunting leak, and cause the phenomenon to occur
Main cause include that hydroecium nozzle distortion, hydroecium nozzle sizes differ, water room pressure is excessive and verifying attachment sealing ring
Abrasion etc..It is very harmful that verifying attachment ejection is brought, because verifying attachment is iron piece, power when device is ejected by air pressure
Degree is very big, gently then damages product and equipment, heavy then pound with operator, causes the damage of personnel and equipment.
The content of the invention
The purpose of the present invention is exactly that providing one kind prevents unexpected ejection for the defect that overcomes above-mentioned prior art to exist
Safe leakage detection apparatus.
The purpose of the present invention can be achieved through the following technical solutions:A kind of safety leak detection for preventing unexpected ejection is filled
Put, the sealing for checking radiator water chamber, it is characterised in that including vexed bar, spanner, stop collar, lower lock block, spring, card
Pawl and seal head, described lower lock block are positioned in stop collar, and spring groove is provided with the middle of lower lock block, and described spring is placed in bullet
In spring groove, and between stop collar and lower lock block, described claw is positioned in stop collar, and claw side wall is provided with end
The grab for extending internally, the lower surface of the grab is against on lower lock block, and claw front end is provided with buckle, and buckle is convex with the hydroecium mouth of pipe
Play edge to be adapted, described seal head is positioned in claw and props up the upper surface of grab, described vexed bar is from stop collar bottom
Portion is inserted, and is fixed after sequentially passing through stop collar, spring, lower lock block, claw and seal head, and described spanner is fixed on vexed bar,
Its front end props up stop collar;
During leak detection, seal head is first filled in into the hydroecium mouth of pipe, then push spanner, stop collar pressing spring, bullet under spanner effect
Spring causes that lower lock block pushes grab, and then pushes seal head and block the hydroecium mouth of pipe;Meanwhile, the hydroecium mouth of pipe, buckle are encased outside claw
Buckled with hydroecium mouth of pipe raised brim so that leakage detection apparatus are closely connected with hydroecium, are difficult to be ejected during leak detection.
Described seal head includes upper holder block, caulking gum and packing ring, and described upper holder block, caulking gum and packing ring are successively
It is fixedly connected after through vexed bar, described upper holder block is positioned in claw and props up the upper surface of grab, and grab pushes upper holder block,
And then caulking gum is compressed, caulking gum expansion is so as to sealing orifice.
The outer ring of described upper holder block is provided with annular groove, and sealing ring is provided with the annular groove.
Described stop collar bottom is provided with hollow joint outwardly, and described joint is provided with external screw thread, and described is outer
Screw thread is combined with adjusting nut, in described vexed bar insertion joint, is fixed with adjusting nut, and described spanner front end props up regulation
Nut.
Compared with prior art, by increasing safe block button, when leakage detection apparatus are compressed, buckle is firmly blocked the present invention
The raised brim of the hydroecium mouth of pipe so that leakage detection apparatus will not be because of pressure is excessive or the deformation of hydroecium nozzle sizes, change etc. are many
Factor 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 there are simple structure, easily operated and low cost and other advantages.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Fig. 2 is the profile of the hydroecium mouth of pipe;
Assembling schematic diagram when Fig. 3 is present invention work.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, it is a kind of to prevent the unexpected safe leakage detection apparatus for ejecting, the sealing for checking radiator water chamber
Property, it is characterised in that including vexed bar 12, stop collar 9, lower lock block 7, spring 8, claw 6, upper holder block 4, sealing ring 5, caulking gum
3rd, packing ring 2, nut 1 and spanner 11, described lower lock block 7 are positioned in stop collar 9, and bullet is provided with the middle of described lower lock block 7
Spring groove, described spring 8 is placed in spring groove, and between stop collar 9 and lower lock block 7, on the described side wall of claw 6
The grab 61 that end extends internally is provided with, the described front end of claw 6 is provided with buckle 62, the described tail end of claw 6 insertion stop collar 9
Interior, the described lower surface of grab 61 is against on lower lock block 7, and the outer ring of described upper holder block 4 is provided with annular groove, described sealing
Circle 5 is placed in annular groove, and described upper holder block 4 is positioned in claw 6 and props up the upper surface of grab 61, described stop collar
9 bottoms are provided with hollow joint outwardly, and described joint is provided with external screw thread, and described external screw thread is combined with adjusting nut
10, in the described insertion joint of vexed bar 12, sequentially pass through stop collar 9, lower lock block 7, claw 6, upper holder block 4, caulking gum 3 and pad
Fixed with nut 1 after circle 2, described spanner 11 is fixed on vexed bar 12, and its front end props up adjusting nut 10.
During leak detection, first by the sealing rubber plug intake chamber mouth of pipe of leakage detection apparatus front end, then spanner is pushed, stop collar is in spanner
The lower pressing spring of effect, spring causes that lower lock block pushes grab, and then causes that claw compresses caulking gum so that caulking gum is swollen
It is swollen, serve the effect of sealing orifice;Meanwhile, the hydroecium mouth of pipe is encased outside claw, buckle is buckled with hydroecium mouth of pipe raised brim A,
So that leakage detection apparatus are closely connected with hydroecium, the purpose that leakage detection apparatus are operationally difficult ejection has been reached.
