Abstract
The utility model discloses a kind of high sealing rivet nuts, centre bore is offered in the cylinder, the bottom in the body centre hole is closed, internal screw thread is provided on the inner sidewall of body centre hole lower part, annular groove is offered on body centre hole inner sidewall above internal screw thread, the lateral wall setting of the cylinder is in regular polygon, chamfering is offered in the edges and corners of cylinder regular polygon lateral wall, ring baffle is provided at the top of cylinder, the wedge shaped annular spacing groove in cross section is offered in the bottom of the ring baffle, the sealing ring holding is in annular spacing groove, the utility model advantage is: improving the sealing performance of this high sealing rivet nut；While guarantee cylinder good anti-rotation effect, the ram drag of cold headers is reduced, that is, stamping pressure needed for cold headers stamp out ring baffle is reduced, to reduce difficulty of processing and manufacturing cost.
Description
Technical field
The utility model relates to the technical fields of nut, more particularly to the technical field of rivet nut.
Background technique
Rivet nut is a kind of nut being fastenedly connected by staking form and connected piece, and rivet nut is mainly used
Fixed in the riveting of aluminum profile, however there are following shortcomings for common rivet nut at present: first is that sealing performance compared with
Difference, after staking, such as the liquid such as water are easy to leak at the gap of riveting rivet nut, for certain pairs of sealing performances
More demanding occasion, such as electric vehicle accommodate the battery pack of battery, and sealing effect is often unable to satisfy requirement.Second is that
Service life is shorter, although having part rivet nut to be sealed by the way of placing gasket in staking process at present, so
And in this way, gasket is easy to happen aging, and service life is short, particularly with the sealing of outdoor environment, is using one
After the section time, that is, it is easy to happen drainage.Third is that rivet nut common at present generally uses Cold header to carry out punch forming,
However the structure design of common rivet nut at present is not very rationally, so as to cause stamping pressure needed for cold-heading machining
Greatly, difficulty of processing is big, and manufacturing cost is high.
Utility model content
The purpose of this utility model is exactly that provide a kind of structure in order to solve above-mentioned deficiency simple, is greatly improved close
Effect is sealed, long service life is easy to process, the low high sealing rivet nut of manufacturing cost.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows:
A kind of high sealing rivet nut, it is made of cylinder and sealing ring, offers centre bore in the cylinder, the cylinder
The bottom of body centre bore is closed, internal screw thread is provided on the inner sidewall of body centre hole lower part, above internal screw thread
Annular groove is offered on the inner sidewall of body centre hole, the lateral wall setting of the cylinder is in regular polygon, just polygon in cylinder
The edges and corners of shape lateral wall offer chamfering, and ring baffle is provided at the top of cylinder, open up in the bottom of the ring baffle
There is the annular spacing groove that cross section is wedge shaped, the sealing ring holding is in annular spacing groove.
The lateral wall setting of the cylinder body bottom is tapered.
The sealing ring setting is in polygon corresponding with cylinder lateral wall.
The sealing ring is rubber material.
The utility model is using the above-mentioned attainable beneficial effect of technical solution:
1, since the setting of the cross section of annular spacing groove is wedge shaped, when this high sealing rivet nut with aluminum profile
During carrying out riveting fixation, one is generated along cylinder to sealing ring by the wedge shaped annular spacing groove in ring baffle cross section
Body radial direction and extruding force vertically below, so that sealing ring is closely pressed together at the gap of cylinder and aluminum profile location hole,
Tight closure is carried out to the gap at cylinder and aluminum profile location hole, to greatly improve this high sealing rivet nut
Sealing performance.
2, for this high sealing rivet nut after carrying out riveting fixation with aluminum profile, the bottom of ring baffle is pressed firmly against aluminium
On the upper surface of profile, certain sealing function has been not only acted as, has formed double sealing effect together with sealing ring, and pass through
Ring baffle sets sealing ring cover in annular spacing groove, so that sealing ring and external environment be completely cut off, slows down sealing
The aging speed of circle substantially increases the service life of this high sealing rivet nut.
It 3, is in regular polygon in cylinder since the ring baffle of this high sealing rivet nut is obtained by cold headers punching press
The edges and corners of lateral wall offer chamfering, while guaranteeing cylinder good anti-rotation effect, reduce rushing for cold headers
Pressure resistance reduces stamping pressure needed for cold headers stamp out ring baffle, thus reduce difficulty of processing and manufacture at
This.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of Fig. 1；
Fig. 3 is the present invention looks up structural representation of Fig. 1；
Fig. 4 and Fig. 5 is the riveting schematic diagram of the utility model.
Specific embodiment
As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of high sealing rivet nut, it is made of cylinder 1 and sealing ring 2, in the cylinder
Centre bore 3 is offered in body 1, the bottom of 1 centre bore 3 of cylinder is closed, on the inner sidewall of 1 centre bore of cylinder, 3 lower part
It is provided with internal screw thread 4, offers annular groove 5 on 1 centre bore of cylinder, 3 inner sidewall above internal screw thread 4, the cylinder 1
Lateral wall setting is offered with playing the role of anti-rotation in the edges and corners of 1 regular polygon lateral wall of cylinder in regular polygon 14
Chamfering 8 is provided with ring baffle 6 at the top of cylinder 1, offers the wedge shaped ring in cross section in the bottom of the ring baffle 6
Shape limiting slot 7,2 holding of sealing ring is in annular spacing groove 7, and the setting of sealing ring 2 is in corresponding with 1 lateral wall of cylinder more
Side shape, the sealing ring 2 are rubber material, the lateral wall setting tapered 9 of 1 bottom of cylinder.
As shown in Figure 4, this high sealing rivet nut riveting when, first opened up on aluminum profile 10 one with cylinder 1 outside
The corresponding location hole 11 of side wall, then by the holding from top to bottom of cylinder 1 in the location hole 11 of aluminum profile 10, and passes through annular
Baffle 6 is limited.Then the pipette tips of hand riveter are protruded into the centre bore 3 of cylinder 1, control pipette tips rotation, before pipette tips
The external screw thread in portion is located on the internal screw thread 4 of cylinder 1, and makes 1 annular groove 5 of cylinder as shown in Figure 5 to the progress staking of cylinder 1
The side wall 12 at place occurs crumple and deforms to form clamping section 13, is clamped in the two of aluminum profile 10 by ring baffle 6 and clamping section 13
The fixation of this high sealing rivet nut is riveted on aluminum profile 10 by side.When needing other components being fixed on aluminum profile 10
It when upper, need to be only located on by bolt on the internal screw thread 4 of cylinder 1, and fixed component can will be needed to be fixed on aluminum profile 10.
