A kind of project-welding nut for exempting from welding, it includes：Nut body and panel beating plate, and the coaxial aperture in the panel beating plate, the nut body is made up of two half-nuts, the lower end of the half-nut has card base, the card base, which is located in the coaxial aperture and leant with the inwall of the coaxial aperture, to be contacted, the project-welding nut is coordinated by two half-nuts and its card base with coaxial aperture, limit positioned at panel beating plate nut rotation and release, it is simple and reliable for structure.

Description

A kind of project-welding nut for exempting from welding

Technical field

The utility model is on a kind of project-welding nut for exempting from welding.

Background technology

In existing Design of Mechanical Structure, it will usually largely the weldering of project-welding nut occur in the connection procedure of vehicle body sheet metal Connect scheme.

And in existing this design, the connection scheme of project-welding nut：Project-welding nut is connected by projection welder Onto the metal plate connected with hole position, connected by this metal plate, can make it that substantial amounts of parts are direct or indirect in automobile Formation mechanically connect.

Under a part of occasion, after in welding of projection welded nut on metal plate, if close to metal plate side Part occur in that the situation released, may result in whole project-welding nut be again coupled to seem unreliable.

Now releasing due to project-welding nut, may result in whole project-welding nut be again coupled to be accomplished by close to projection welding Nut side, to project-welding nut is fixed, then will tighten operation, in this case, will have whole operation certain Inconvenience.

Utility model content

The utility model provides a kind of project-welding nut for exempting from welding, and it includes：Nut body and panel beating plate, and it is described Coaxial aperture in panel beating plate, wherein：The nut body is made up of two half-nuts, and the lower end of the half-nut has card base, The card base, which is located in the coaxial aperture and leant with the inwall of the coaxial aperture, to be contacted.

Project-welding nut in the utility model is coordinated by two half-nuts and its card base with coaxial aperture, is limited positioned at metal plate The nut rotation of golden plate and release, it is simple and reliable for structure.

Brief description of the drawings

Fig. 1 is the utility model exploded perspective view；

Fig. 2 is schematic diagram before the utility model assembling；With

Fig. 3 is schematic diagram after the utility model assembling.

Reference：Nut body 1, panel beating plate 2, coaxial aperture 3, card base 4, boss 5, main half-nut 6, secondary half-nut 7, spiral shell Bolt 8, gap 9.

Embodiment

As shown in Figures 1 to 3, the utility model provides a kind of project-welding nut for exempting from welding, and it includes：The He of nut body 1 Coaxial aperture 3 in panel beating plate 2, and the panel beating plate 2, wherein：The nut body 1 is made up of two half-nuts, and described half The lower end of nut has a card base 4, and the card base 4 is located in the coaxial aperture 3 and offseted with the inwall of the coaxial aperture 3 and is abutted against Touch.

Project-welding nut in the utility model is coordinated by two half-nuts and its card base with coaxial aperture, and card base is located at coaxial It is in hole and spacing by hole wall, thus formed limit positioned at metal plate plate surface nut rotation and release, it is simple and reliable for structure.

As a further improvement, the end of the card base 4 has the boss 5 of axial limiting prominent laterally, and institute State the outer end that boss 5 is located at the coaxial aperture 3.Boss 5 forms spacing on the axial direction between nut and coaxial aperture.

As a further improvement, the nut body 1 is rectangle, and the coaxial aperture 3 is rectangular opening.

As a further improvement, the half-nut includes：In the main half-nut 6 of big rectangle, and in secondary the half of small rectangle Nut 7.

As a further improvement, bolt 8 passes through the rectangular opening and the main half-nut 6 and the spiral shell of secondary half-nut 7 Line is connected, and the formation gap 9 between the main half-nut 6 and the secondary half-nut 7.

In preferred embodiment of the present utility model, it uses the combination of the main half-nut 6 and the secondary half-nut 7, And the two has the difference in size, while the two all has a card base and its boss to act on the coaxial aperture of panel beating plate in lower end On.

During operation, the main half-nut 6 is normally put into after coaxial hole position, and secondary half-nut 7 can be inserted close to main half-nut 6 And assemble in place, after two half-nuts open, then twist bolt.

Preferred embodiment of the present utility model is realized well exempts from weldering connection between whole project-welding nut and panel beating plate, The convenience of the project-welding nut connection under particular application can greatly be improved, is brought greatly just to whole production Profit.

It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims The scope of offer, and its dependent claims.
