Description
Technical field
The utility model is related to rivet more particularly to a kind of lantern rivets of enhancing sealing.
Background technology
Rivet refers to the part for being riveted part using self-deformation or interference connection in riveting, and rivet is as a kind of common
Fixedly connected part, be fixed by dedicated hand riveter, easy to operate, application range is extremely extensive, and existing rivet is in riveting
Often there is loose phenomenon between riveting object after connecing, directly affects its usability and safety.Lantern rivet is in a rivet body
Between the rivet slotted, in riveting, rivet body drum opens the forced area for increasing and being riveted between part, can play certain locking
Action is used.
After staking, after the completion of riveting, blind rivet can not be filled up completely in rivet body existing lantern rivet for blind rivet and rivet body
Hole causes the outer end at the top of rivet body to form larger hole, and the hole being easy between blind rivet and rivet body affects lantern rivet
Water resistance, poor sealing.In order to solve the problem of its waterproof poor sealing, each manufacturing enterprise when producing rivet body,
Outside annular protrusion is processed with the integrally formed head of a nail outer end face of rivet body, is extruded using annular protrusion and fills blind rivet and riveting
Hole between body, but the processing of this rivet body is cumbersome, and high processing costs are unfavorable for market sale, need to improve.
Utility model content
The purpose of this utility model is to provide a kind of lantern rivets of enhancing sealing, improve sealing performance, processing is simple
It is convenient, it is of low cost.
For this purpose, the utility model uses following technical scheme：
A kind of lantern rivet of enhancing sealing, including riveting shell ontology and blind rivet, the blind rivet are penetrated from riveting shell ontology bottom end
It is pierced by afterwards from top, the head of a nail has been wholely set at the top of the riveting shell ontology, the riveting shell ontology circumferencial direction offers several
Vertical slot, the head of a nail outer end are spherical surface body, and the blind rivet is in axial direction disposed with cylindrical type boss, cylinder and nail
The outer diameter of bar, the cylinder boss is more than cylinder outer diameter, and the outer diameter of the cylinder is more than nail rod outer diameter, the cylinder two
End is respectively arranged with helicitic texture.
Wherein, one end that the cylindrical type boss is connect with cylinder is provided with rounded corner.
Wherein, one end that the cylinder is connect with nail rod is provided with breakpoint.
Wherein, the cylinder is that interference fit connects with riveting shell ontology endoporus.
Wherein, the head of a nail inner face indent is provided with annular groove.
Wherein, the one end of the nail rod far from cylinder is provided with external screw thread.
The beneficial effects of the utility model：A kind of lantern rivet of enhancing sealing, in riveting, cylinder in blind rivet without
Gap gets lodged in head of a nail endoporus, is combined closely, is improved by the helicitic texture and riveting shell ontology endoporus at cylinder both ends
The defect that the waterproof of lantern rivet, dust protection, anti-gas are omitted, sealing effect is more preferable, and processing is simple and convenient, efficient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is blind rivet structural schematic diagram.
Specific implementation mode
The technical solution of the utility model is further illustrated with reference to Fig. 1 ~ 2 and by specific embodiment.
A kind of lantern rivet of enhancing sealing, including riveting shell ontology 1 and blind rivet 2, the blind rivet 2 is from 1 bottom end of riveting shell ontology
It is pierced by from top after penetrating, the top of the riveting shell ontology 1 has been wholely set the head of a nail 3, and 1 circumferencial direction of riveting shell ontology opens up
There are several vertical slots 11, vertical slot 11 to be evenly arranged with 3 on riveting shell ontology 1, blind rivet 2 is pulled and the head of a nail 3 is made to squeeze riveting shell sheet
Body 1 makes two to be riveted part and is clamped at the riveting shell ontology that drum is opened to make riveting shell ontology 1 be opened in 11 position outward bulge of vertical slot
Between 11 and the head of a nail 3, to increase riveting contact area, rivet compactness is improved.
3 outer end of the head of a nail is spherical surface body, easy to process, traditional that annular protrusion, processing are also added with outside the head of a nail
Program is cumbersome, of high cost.
The blind rivet 2 is in axial direction disposed with cylindrical type boss 21, cylinder 22 and nail rod 23, and the cylinder is convex
The outer diameter of platform 21 is more than 22 outer diameter of cylinder, and the outer diameter of the cylinder 22 is more than 23 outer diameter of nail rod, 22 both ends of the cylinder
It is respectively arranged with helicitic texture 221, in riveting process, by blind rivet 2 to 1 pull of riveting shell ontology, cylinder 22 enters riveting gun
It is squeezed in riveting shell ontology 1, helicitic texture 221 is extruded and diameter becomes larger, and is combined closely completely with 1 endoporus of riveting shell ontology, and is justified
One end of cylinder 22 is combined with 3 internal control of the head of a nail my slots close completely by pull to the endoporus of the head of a nail 3, is improved sealing performance.
In the present embodiment, one end that the cylindrical type boss 21 is connect with cylinder 22 is provided with rounded corner, transitions smooth,
Do not occur stuck.
In the present embodiment, one end that the cylinder 22 is connect with nail rod 23 is provided with breakpoint 24, when rivet, profit
It is disconnected at breakpoint 24 with riveting gun.
In the present embodiment, the cylinder 22 is that interference fit connects with 1 endoporus of riveting shell ontology.
In the present embodiment, 3 inner face indent of the head of a nail is provided with annular groove 31, and the head of a nail is fitted in convenient for outer spacer
3 annular grooves 31 enhance sealing performance.
In the present embodiment, the one end of the nail rod 23 far from cylinder is provided with external screw thread 231, when nail rod 23 is in riveting gun
It is interior by pull when, external screw thread 231 have preferable non-skid property.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
