Description

Temperature-resistant deformation-resistant rivet

Technical Field

The utility model relates to the technical field of rivets, in particular to a temperature-resistant and deformation-resistant rivet.

Background

Rivets are nail-shaped articles used to connect two parts (or members) with through holes and a cap at one end. In riveting, the riveted parts are connected by self-deformation or interference. Rivets are of many kinds and are not limited in form. R-shaped rivets, fan rivets, blind rivets (core-impacting rivets), tree rivets, half-round heads, flat heads, half-blind rivets, solid rivets, countersunk rivets, blind rivets and blind rivets are commonly used, and these are usually connected with the riveted part by self-deformation.

Generally, the rivet is broken through the rivet gun, so that a part of parts of the rivet are fixed on an object, but the broken part cannot be reused, so that the parts of the rivet are wasted, and the parts are small and difficult to recycle.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a temperature-resistant deformation-resistant rivet.

In order to achieve the purpose, the utility model adopts the following technical scheme:

anti-temperature shape rivet of preapring for an unfavorable turn of events, the female joint comprises a sleeve pipe, the cover inside pipe wall spiro union has the bolt, and the equal fixedly connected with spacing collar of cover both ends outer wall, the sealing cap has been cup jointed to the spacing collar outer wall, the cover outside pipe wall is provided with the extrusion strip that the equidistance distributes, and the cover inside pipe wall is located the relative one side of extrusion strip and sets up the extrusion groove that the equidistance distributes, the cover outside pipe wall is located the solid fixed ring of one end fixedly connected with of extrusion strip.

Preferably, the inner wall of the sleeve is provided with an internal thread groove, and the size of the external thread on the outer wall of the bolt is matched with that of the internal thread groove.

Preferably, the outer walls of the two limiting rings are fixedly connected with anti-slip strips distributed equidistantly, and interference fit is formed between the sealing caps and the limiting rings.

Preferably, the outer wall of the bolt is sleeved with a gasket, and the outer diameter of the gasket is smaller than that of the limiting ring.

Preferably, the outer wall of one end of the bolt is provided with a hexagonal groove.

Preferably, the outer wall of the sealing cap is provided with symmetrically distributed bulges.

The utility model has the beneficial effects that:

1. according to the temperature-resistant deformation-resistant rivet, after the rivet is fixed on an object, the bolt can be screwed out of the sleeve through the reverse rotation of the riveting machine, the bolt can be reused, and the waste of rivet parts is avoided;

2. this resistance to temperature shape rivet of preapring for an unfavorable turn of events of design, after the object passes through rivet riveting, when emboliaing two spacing rings respectively with two sealed caps, can guarantee the leakproofness at sleeve pipe both ends, avoided some pollutants such as dust, water to enter into the inside of object.

In the figure: the anti-skid device comprises a sleeve 1, a bolt 2, a limiting ring 3, a sealing cap 4, an extrusion strip 5, a fixing ring 6, an internal thread groove 7, an anti-skid strip 8, a gasket 9, a hexagonal groove 10 and a bulge 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Embodiment 1, refer to fig. 1-3, a temperature-resistant deformation-resistant rivet comprises a sleeve 1, a bolt 2 is screwed on the inner wall of the sleeve 1, the outer walls of two ends of the sleeve 1 are fixedly connected with limit rings 3, the outer wall of the sleeve 1 is provided with extrusion strips 5 distributed equidistantly, extrusion grooves distributed equidistantly are formed in one side, opposite to the extrusion strips 5, of the inner wall of the sleeve 1, a fixing ring 6 is fixedly connected to one end, located on the extrusion strips 5, of the outer wall of the sleeve 1, a rivet machine is used for reversely rotating the bolt 2 out of the sleeve 1, the bolt 2 can be reused, and waste of rivet parts is avoided;

interior thread groove 7 has been seted up to sleeve pipe 1 inner wall, and the external screw thread size on the bolt 2 outer wall and 7 size looks adaptations of interior thread groove, and 2 outer wall covers of bolt are equipped with gasket 9, and the external diameter of gasket 9 is less than the external diameter of spacing collar 3, and hexagonal groove 10 has been seted up to 2 one end outer walls of bolt.

Embodiment 2, referring to fig. 1 to 3, this embodiment is optimized on the basis of embodiment 1, specifically:

3 outer walls of spacing collar have cup jointed sealed cap 4, after the object passes through rivet riveting, when emboliaing two spacing collars 3 respectively with two sealed caps 4, can guarantee the leakproofness at sleeve pipe 1 both ends, avoided the inside that some pollutants such as dust, water enter into the object, the 3 outer walls of two spacing collars equal fixedly connected with equidistant antislip strip 8 that distributes, and form interference fit between sealed cap 4 and the spacing collar 3, the arch 11 of symmetric distribution is seted up to sealed cap 4 outer wall.

The working principle is as follows: coating the high temperature resistant thermal-insulated coating of one deck at the surface of rivet, the effect of preapring for an unfavorable turn of events shape has fine temperature resistance, during the installation rivet, at first with solid fixed ring 6 be close to the surface of extrusion strip 5 one side laminating at needs riveted object, after fixed solid fixed ring 6 is good, then through riveter swivel bolt 2, extrusion groove can take place the bending and fix the object between solid fixed ring 6 and extrusion strip 5 this moment, later reverse rotation bolt 2, screw out in following sleeve pipe 1 with bolt 2, cover sealing cap 4 on the outer wall of spacing collar 3 at last.
