Abstract

The utility model disclosed a riveting nut which comprises a nut body provided with an internal thread through a hole in the middle, one end of the internal thread through hole extends outwards to form an integrally formed ring-shaped boss, one side face of the nut body, connected with the ring-shaped boss, is provided with a ring-shaped groove encircling the ring-shaped boss, and the outer side face of the ring-shaped boss is provided with a plurality of inclined surfaces. The riveting nut is simple in structure and convenient to use, and can improve fixing, connecting strength and torsion strength between the riveting nut and metal plate in use.

Description

A kind of riveting nut

Technical field

The utility model relates to a kind of riveting nut, particularly a kind of riveting nut that connects with panel beating by riveting process.

Background technique

Nut is connected with panel beating, it is existing that domestic what generally adopt is that the bruising welding procedure connects, the shortcoming that this technique exists in actual use has: in (1) bruising weldering process,, face of weld different owing to the leg height has the reasons such as greasy dirt, easily produce the damage of electrical spark so that screw thread, in addition, can produce obvious ablation vestige, affect the product appearance quality; (2) electrode welder causes quick abrasion owing to being under high temperature, the high pressure for a long time, and the location is inaccurate, and nut easily departs from the welding position, causes installation dimension unstable; (3) because present domestic multi-head welder technology is immature and the equipment investment cost is large, therefore, the existing one head arc welding machines that adopt more, can only the single-point bruising welding so that manufacturing efficiency is low, and when for identical product a plurality of nut being arranged, need multiple bearing, equally easily cause installation dimension unstable; The drift of issuable voltage functuation and apparatus settings parameter when (4) welding, the reliability of its weld strength has very large uncertainty, and not detectable degree is very high, unless carry out destructive test; (5) electric power of welding machine is large, wastes energy, and simultaneously easily produces spark and a large amount of smog in welding process, and operating personnel's personal safety and working environment had certain impact.

Existing domestic except employing bruising welding procedure connects, also adopt project-welding nut to connect, referring to shown in Figure 1, project-welding nut 10 is provided with projection welding fusing point 11 with the junction of panel beating 20, project-welding nut 10 relies on the Multi-point high temperature fusing to be combined with panel beating, with the intensity of electric current direct relation is arranged, its technique is unstable, intensity is not high.

The model utility content

The technical problems to be solved in the utility model provides a kind of simple in structure, easy to use, can improve fixing, join strength between riveting nut and the panel beating and a kind of riveting nut of torsional strength in when welding.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of riveting nut, comprise that the middle part is provided with the nut main body of internal thread through hole, one end of described internal thread through hole stretches out and forms integrated round ring boss, the side that described nut main body is connected with round ring boss is provided with the toroidal cavity around round ring boss, and the outer side surface of described round ring boss is provided with several overhead kick inclined-planes.

In an embodiment of the present utility model, described nut main body is square or rectangular.

In an embodiment of the present utility model, described toroidal cavity arrives the distance of nut main body outer side surface less than toroidal cavity to the distance at nut main body center.

In an embodiment of the present utility model, the axis of described round ring boss and internal thread through hole point-blank.

By technique scheme, the beneficial effects of the utility model are:

The utility model is simple in structure, easy to use, and constant intensity and torsional strength are the several times of common project-welding nut and panel beating linking intensity when connecting with panel beating.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 2 and shown in Figure 3, a kind of riveting nut of the utility model comprises that the middle part is provided with the nut main body 10 of internal thread through hole 11, one end of internal thread through hole 11 stretches out and forms integrated round ring boss 20, adopt integral forming process have advantages of easy to process, cost is low; The side that nut main body 10 is connected with round ring boss 20 is provided with the toroidal cavity 30 around round ring boss 20, and the outer side surface of round ring boss 20 is provided with several overhead kick inclined-planes 21.

The utility model nut main body 10 is square or rectangular, and toroidal cavity 30 arrives the distance of nut main body 10 outer side surfaces less than toroidal cavity 30 to the distance at nut main body 10 centers.

The axis of the utility model round ring boss 20 and internal thread through hole 11 point-blank.

Referring to shown in Figure 4, the utility model when mounted, the hole of at first panel beating 40 being reserved such as riveting nut round ring boss 20 sizes, then boss 20 is enclosed within on the hole of panel beating 40, then utilize rushing of punching press lathe the panel beating material can be extruded in the barb inclined-plane 21 times and toroidal cavity 30 on round ring boss 20 outer side surfaces, like this riveting nut having fixed on the panel beating 40 inflexibly just; Its pull-out force is up and down provided by barb inclined-plane 21, and its left rotation and right rotation moment of torsion is supported by toroidal cavity 30.

Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
