Abstract

The utility model relates to an expansion type rivet nut, which includes a cap edge, a deformation skirt section and a nut cylinder. The deformation skirt section of the cap edge is a thin wall hollow cylinder; the nut cylinder is an internal thread through hole; the outer circle is a conical cylinder; the smaller end of the conical cylinder is connected with the deformation skirt section and is a rupture. The expansion type rivet nut utility model is applicable for the expansion rivet nut usable for thick, thin plates, soft and hard materials with a strong anti-shearing force, which has a single side riveting function and can carry out a single side welding for a blind hold with easy operation.

Description

The expansion Insert Nut
The utility model relates to a kind of Insert Nut, particularly relates to the expansion Insert Nut that a kind of can fastening connection thick, thin-wall boards and soft, hard material can both be used.
In the connection of thin-walled plate, screw is fastening except adopting for people, the welded nut, extensively adopt Insert Nut to connect, and what common Insert Nut adopted is clamping type riveted joint mode, and the blind riveting function is arranged, easy to operate.Retrieve through new patent searching, a kind of low carbon steel Insert Nut fastening piece is promptly disclosed as patent 93210786.9, it constitutes the Insert Nut fastening piece by shade, distortion skirt section, thread filament hole, by special tool the thin plate workpiece is clamped between shade and the distortion skirt section during use, thereby connect other object, easy to operate.
But, in some special industry and occasion, in the connection as industry inner trim panels such as train, automobile, furniture, boats and ships, normal is the slab of soft material, as glass mat, clamping plate etc., prior art just can't realize being fixedly connected, and a kind of low carbon steel Insert Nut fastening piece as patent 93210786.9 is announced can't adapt to soft and riveted joint slab because of it is out of shape skirt section.
The purpose of this utility model is to address the above problem, and provides a kind of adaptation thick, light sheet, the expansion Insert Nut that soft, hard material can both be used, and it has the blind riveting function equally, and is easy and simple to handle, also can implement blind riveting to blind hole.
The technical solution of the utility model is: a kind of expansion Insert Nut, comprise shade, distortion skirt section and nut Cylinder, distortion skirt section under the shade is the thin-walled hollow cylinder, the nut Cylinder is an internal thread through hole, outer garden is the Cylinder of band taper, and taper Cylinder small end is connected with the distortion skirt section and is fracture place.
Therefore the utility model, has the following advantages owing to adopt technique scheme:
1, the shearing resistance after the riveted joint of raising nut.Because Insert Nut is under the effect of staking power, the taper small end of nut Cylinder ruptures with the joint in distortion skirt section, and the taper small end of nut Cylinder is drawn in the endoporus into the distortion skirt section, thereby makes distortion skirt section external diameter expansion chap, the hole of locking workpiece.The taper small end of nut Cylinder reaches the actinal surface concordant with shade when staking is finished, and the endoporus in whole like this distortion skirt section is filled up by the nut Cylinder, thereby has improved the shearing resistance after the riveted joint.
2, because the special mode of texturing of this Insert Nut can be fastened on the hardened member it, also can be fastened on the soft material, thick, the thin unrestricted and influence of riveted joint workpiece connects so that can both realize riveted joint on blind hole.
The structural representation of Fig. 1, the utility model expansion Insert Nut.
The working state figure of Fig. 2, the utility model expansion Insert Nut.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shade (1), distortion skirt section (2), nut Cylinder (3), internal thread through hole (4), taper Cylinder (5), taper Cylinder fracture place (6).
Referring to Fig. 1, the utility model expansion Insert Nut is made of shade (1), distortion skirt section (2) and nut Cylinder (3), shade (1) is one auspicious distortion skirt section (2), it has several leading kind of form of countersunk head peace, distortion skirt section (2) is a hollow cylinder, its wall can be thinner, is easy to stress deformation.Auspicious at another of distortion skirt section (2) is the Cylinder nut (3) that endoporus has screw thread (4), and its external diameter is circular cone (a 5) shape, taper Cylinder (5) small end be out of shape skirt section (2) and be connected.
Referring to Fig. 1,2, the expansion Insert Nut is put into the corresponding hole of workpiece, then, the rifle head is put into the hole of expansion Insert Nut, the rotation of rifle head makes the helical thread portion (4) of expansion Insert Nut move to shade (1) direction, under the effect of this rivet force, when reaching certain limit, the taper small end (5) of Cylinder nut (3) will rupture with the joint (6) in distortion skirt section (2), and the taper small end (5) of fracture back cylindrical body nut (3) will enter inside the endoporus in distortion skirt section (2), until arriving the concordant actinal surface of shade (1), like this, distortion skirt section (2) will all be full of by nut cylindrical body (3), and outwards expand, thereby the locking workpiece is implemented riveted joint.Because nut Cylinder (3) all enters in the distortion skirt section (2), has increased the radial thickness of distortion skirt section (2), thereby improved the shearing resistance of riveted joint.Its grip scope is also very wide, even can the riveted fixing blind hole.

Claims (1)

1. expansion Insert Nut, comprise shade (1), distortion skirt section (2) and nut Cylinder (3), it is characterized in that: the distortion skirt section (2) under the shade (1) is the thin-walled hollow cylinder, nut Cylinder (3) is internal thread through hole (4), outer garden is the Cylinder (5) of band taper, and taper Cylinder (5) small end is connected with distortion skirt section (2) and is fracture place (6).
