Description
Technical field
The utility model relates to a kind of spring button bars, more particularly to a kind of spring for steel-pipe furniture folding joint
Button spindle.
Background technique
The spring button bar that can be used on steel-pipe furniture folding joint generally comprises rivet bar, spring and big cap, rivet
After bar passes through position to be mounted, upper spring is covered, then weld big cap.It due to needing to weld and polish, and is furniture face
Color is integrally unified, after assembling, it is also necessary to pickling and 200 celsius temperature baking vanish are carried out, pickling and high temperature will lead to camber of spring,
It is also easy to that material is made to soften and cause to scrape paint, is unfavorable for the service life of product, and production low efficiency.
Utility model content
The purpose of the utility model is to overcome the deficiencies of the prior art, provide a kind of spring button bar.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of spring button bar, it is characterised in that: it includes the first rivet bar, spring and the second rivet bar, and described first
The head end of rivet bar is equipped with the first cap, and the breech face of first rivet bar concaves as heart shaped in midair, second rivet
The head end of bar is equipped with the second cap, and the outer wall of the body of rod of second rivet bar is equipped with self tapping thread or hangnail, second riveting
The outer diameter of the tail end of nail rod is greater than the internal diameter of the tail end of first rivet bar, and first rivet bar passes through to be mounted
The spring is inserted in after mounting hole, the body of rod of second rivet bar is inserted into the semi-hollow tail end of first rivet bar and leads to
Cross the self tapping thread or hangnail be fixed on the first rivet bar semi-hollow tail end inner wall.
In a further preferred embodiment, the breech face of second rivet bar sets to the concave for heart shaped in midair, and through rushing
Compression swelling or fluting expansion.
In a further preferred embodiment, bar diameter of second rivet bar by the part of near head end is greater than the center portion in midair
The bar diameter divided.
In a further preferred embodiment, the tail end of second rivet bar is equipped with axial fluting.
The utility model has the beneficial effects that due to using rivet bar and semi-hollow riveting with self tapping thread or hangnail
Nail rod is fixedly connected, and the existing design that compares has the advantages that the processing is simple and beautiful, due to not having to welding and polishing, production
High-efficient, and can assemble again after spray coating, the prior art that compares needs to assemble in ironware, then will also through overpickling and
200 celsius temperature baking vanish have better efficiency and effect.Using the structure of the utility model, three components can all exist
Dust and hot setting powder after assemble, product is zinc-plated will not to scrape paint and wear-resisting；It is expanded or is slotted using punching press and expanded, so that
Connection between two rivets is more stable；And it can be on the second cap of the second rivet bar or the first cap of the first rivet bar
Printing or imprint pattern.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of bullet of the utility model
Spring button spindle is not limited to the embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the embodiments of the present invention one are mounted on folding joint.
Fig. 2 is the rivet bar of the embodiments of the present invention one and the decomposition texture schematic diagram of big cap.
Fig. 3 is the rivet bar of the embodiments of the present invention one and the decomposition diagrammatic cross-section of big cap.
Fig. 4 is the rivet bar of the embodiments of the present invention two and the decomposition diagrammatic cross-section of big cap.
Specific embodiment
Embodiment one, referring to shown in Fig. 1 to Fig. 3, a kind of spring button bar of the utility model comprising the first rivet bar
1, the head end of spring 2 and the second rivet bar 3, first rivet bar 1 is equipped with the first cap 11, the tail of first rivet bar 1
End face concaves as heart shaped in midair, and the head end of second rivet bar 3 is equipped with the second cap 31, the bar of second rivet bar 3
The outer wall of body is equipped with self tapping thread 32 and in other embodiments is also possible to that hangnail is distributed on the outer wall；Second rivet
The breech face of bar 3 sets to the concave as heart shaped in midair, bar diameter of second rivet bar 3 by the part of near head end be greater than it is described in midair
The bar diameter of center portion point.First rivet bar 1 is inserted in the spring 2, punching press after passing through the mounting hole on component 4 to be mounted
The body of rod of second rivet bar 3 is inserted into the semi-hollow tail end of first rivet bar 1 by extrusion expansion and by described
Self tapping thread 32 is fixed on the inner wall of the semi-hollow tail end of the first rivet bar 1.
Embodiment two, the present embodiment and embodiment one the difference is that: the tail end of second rivet bar 3 is equipped with axis
To fluting 33, pour the semi-hollow tail end of the first rivet bar 1, fluting 33 is squeezed, and the inflating clip that cracks is in the first rivet bar 1
It is interior.
Above-described embodiment only is used to further illustrate a kind of spring button bar of the utility model, but the utility model is not
It is confined to embodiment, it is any simple modification made by the above technical examples according to the technical essence of the present invention, equivalent
Variation and modification, each fall in the protection scope of technical solutions of the utility model.
