Description
Technical field
The utility model belongs to a kind of rivet column sealing technical field, and in particular to a kind of sealing for self-clinching stud column
Device.
Background technology
Sale temporarily without rivet column sealing device currently on the market, when in use due to self-plugging rivet, rivet mandrel is by special
It is pulled with riveting gun, rivet body is made to expand, play the role of riveting, so can be left on rivet body cap after the extraction of self-plugging rivet blind rivet crooked
The metal aperture to differ；Especially in coastal area, exposed metal aperture can cause product appearance inconsistent and exposed
Metal aperture is easily intake and is corroded.
Existing rivet can not apply the occasion high in seal request, seriously affect the use scope of rivet.
Utility model content
Technical problem to be solved in the utility model is to provide one kind in view of the above shortcomings of the prior art for pressing
The sealing device of screw pole, simple in structure, not only cylinder is sealed at hole after riveting, and two ends position also seals, and is had double
Resealing function.
To realize the above-mentioned technical purpose, the technical solution that the utility model is taken is：
A kind of sealing device for self-clinching stud column, wherein：Including upper plastic tube, rivet, the first sealing ring, upper plate,
Lower plate, the second sealing ring, lower plastic tube and third sealing ring, the lower plastic tube are fixedly mounted in plastics bottom of the tube
In heart hole and the centre bore band of upper plastics bottom of the tube is tapered, and the rivet is mounted in the centre bore of upper plastic tube and rivet
First sealing ring is installed between head bottom surface and upper plastic tube top surface, the upper plastic tube using " T " shape structure form and
Upper plastics pipe orifice is interference fit with rivet external cylindrical surface, and the upper plate is mounted in the outside cylinder of upper plastic tube and upper plate
Top surface is withstood on the bottom surface of plastics pipe flange, and the lower plate is mounted in the outside cylinder of upper plastic tube and lower plate top surface top
On the bottom surface of upper plate, second sealing ring is mounted between rivet tail portion and lower plastic tube bottom surface, and the third is close
Seal is mounted between lower plate bottom surface and the top surface of lower plastics pipe flange.
To optimize above-mentioned technical proposal, the concrete measure taken further includes：
Above-mentioned upper plastic tube and lower plastic tube are all made of to use polytetrafluoroethylene or nylon material.
It is interference fit between the mounting hole of above-mentioned upper plate and the outside cylinder of upper plastic tube.
It is interference fit between the mounting hole of above-mentioned lower plate and the outside cylinder of upper plastic tube.
After upper plastic tube and lower plastic tube are combined into one by the utility model, then by suit on rivet by polytetrafluoroethylene
Or combined plastic pipe made of the materials such as nylon, therefore the processing technology of riveting part with it is above it is several compared with it is more best.Combination
Plastics pipe orifice and the sealing that rivet is that interference fit realizes rivet external cylindrical surface；Combined plastic pipe outer circle and upper plate and lower plate
Cooperation be all made of press-fit HS/k7, and plastic tube length of bench is greater than 0.2~0.4mm of riveting part thickness.Therefore, after riveting
Not only cylinder is sealed at hole, and two ends position also seals, and has dual-seal work(.
The utility model has the advantage of the followings：Simple in structure, not only cylinder is sealed at hole after riveting, two ends
Position also seals, and has the function of dual-seal.
