Abstract

The utility model relates to a highly-locking double-tooth rivet nut comprising a round-tube-shaped rivet tube body. One end of the rivet tube body is provided with a cap edge body, and the inner hole wall of the other end of the rivet tube body is provided with an inner thread to form a thread hole. The outer wall of the rivet tube body is provided with an outer thread. The position of the outer thread corresponds to that of the inner thread. As the outer thread is arranged on a position, same as that of the inner thread of the rivet tube body, of the outer wall, the rivet nut has double thread teeth, and the inner thread can be connected with work-pieces through other thread fastening parts to achieve connecting and fastening functions of a common rivet nut. Simultaneously, the outer thread can individually screw the rivet nut into a connecting work-piece to achieve an independent fastening function as a bolt and enlarge use range.

Description

The two tooth Insert Nuts of high lock

Technical field

The utility model relates to a kind of Insert Nut, specifically a kind of two tooth Insert Nuts of height lock with inside and outside two screw-threaded coupling effects.

Background technique

At present, in the riveted joint of sheet material, what be used for riveting parts all is traditional plain edition Insert Nut.This Insert Nut is comprised of riveting tube body, the thread filament hole that is positioned at the shade of riveting tube body one end and is positioned at the riveting tube body the other end, and shade wherein is as the positive stop lug boss in the riveted joint process; The centre is the distortion skirt section of hollow; Tail end is a guiding frustum.

The screw thread that the plain edition Insert Nut can only utilize its single effect after staking by being connected with workpiece with other threaded fastener, but can't satisfy and to be connected with workpiece after the staking and can be as the independent fastening multi-functional connection request of bolt, so not only limit the use of product but also limited to product function, also increase simultaneously the complexity of client's Product Process, caused the rising of client's product cost.

Summary of the invention

The utility model is to the problems referred to above, provide a kind of can be after riveted joint by with other threaded fastener workpiece being connected and can be as the two tooth Insert Nuts of the independent fastening height lock of bolt.

The technological scheme that provides according to the utility model: the two tooth Insert Nuts of a kind of high lock, the riveting tube body that comprises tubular shape, one end of described riveting tube body is provided with the shade body, be provided with internal thread on the inner hole wall of its other end and form thread filament hole, be provided with outside thread on the outer wall of described riveting tube body, described externally threaded position is corresponding with described internal thread.

Described outside thread adopts reinforced coarse thread.

Described externally threaded end is provided with and is the guiding surface that draws shape in.

The end face of described shade body is the plane.

Technique effect of the present utility model is: the utility model is provided with outside thread at the outer wall of riveting tube body internal thread co-located, make Insert Nut have two threads, internal thread can be connected with workpiece by other threaded fastener, realize connecting fastening common Insert Nut function, outside thread can be screwed into Insert Nut separately again one connection workpiece simultaneously, realization has enlarged using scope as the independent fastening function of bolt.

Description of drawings

Fig. 1 is the structural representation that partly cuts open of the present utility model.

Fig. 2 is that the utility model partly cuts open structural representation when in running order.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

Among Fig. 1, Fig. 2, comprise shade body 1, riveting tube body 2, outside thread 3, internal thread 4, guiding surface 5, riveted joint workpiece 6, workpiece 7, bulge 8.

As shown in Figure 1, the utility model is the two tooth Insert Nuts of a kind of high lock, comprises the riveting tube body 2 of tubular shape, and an end of riveting tube body 2 is provided with the shade body 1 of bulge loop shape, and the end face of shade body 1 is the plane; Be provided with internal thread 4 on the inner hole wall of its other end and form thread filament hole.Outer wall at riveting tube body 2 is provided with outside thread 3, and the position of outside thread 3 is corresponding with internal thread 4, and outside thread 3 adopts reinforced coarse thread.

The end of outside thread 3 also is provided with and is the guiding surface 5 that draws shape in, play the guiding role.

As shown in Figure 2, when workpiece is riveted, rifle head on the Riveting Tool passes shade body 1 and riveting tube body 2 screws mutually with internal thread 4, then utilizing together the guiding surface 5 of outer ends to insert in the hole of holding successfully in advance on the riveted joint workpiece 6 is pulled outwardly, outwards expanded in stressed formation distortion skirt section, riveting tube body 2 upper ends, until in the 6 inboard bulges 8 that form a Lantern of riveted joint workpiece, riveted joint workpiece 6 is clamped between this Lantern bulge 8 and the shade body 1 as positive stop lug boss, and finishes single riveted joint.Just can utilize the outside thread 3 on the internal thread 4 co-located outer walls to be screwed into workpiece 7 this moment, independent fastening to realize bolt.

Because Insert Nut of the present utility model has two threads, i.e. the outside thread 3 of internal thread 4 co-located outer walls setting.Internal thread 4 is connected with workpiece by other threaded fastener, realize connecting fastening common Insert Nut function, utilize simultaneously the outside thread 3 on the outer wall Insert Nut can be screwed into separately a connection workpiece, realize having enlarged using scope as the independent fastening function of bolt.

The utility model can directly reach by a plurality of processing purposes of riveted joint workpiece, reduced the complexity of workpiece processing, avoided board workpiece in the past by after riveting with technique and the mass defect of generation during other multi-work piece is connected.
