Abstract
It is a kind of have can self-locking function project-welding nut, it includes：Coaxial aperture in nut body and panel beating plate, the panel beating plate, and the inner core body being threadedly coupled with the nut body, the lower end of the inner core body has card base；And there is hole clipping in the panel beating plate, and the card base is located in the hole clipping, the project-welding nut is coordinated by card base and hole clipping, and auto-lock function is realized in nut body and inner core body cooperation, prevents the superstructure loosening of service stage.
Description
Technical field
The utility model on it is a kind of have can self-locking function project-welding nut.
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 provide it is a kind of have can self-locking function project-welding nut, it includes：Nut body and panel beating plate,
And the coaxial aperture in the panel beating plate, wherein：It also includes：The inner core body being threadedly coupled with the nut body, it is described
The lower end of inner core body has card base；And there is hole clipping in the panel beating plate, and the card base is located in the hole clipping.
The utility model is coordinated by card base and hole clipping, and auto-lock function is realized in nut body and inner core body cooperation,
Prevent the superstructure loosening of service stage.
Brief description of the drawings
Fig. 1 is explosive view of the present utility model；
Fig. 2 is the utility model assembling schematic diagram；With
Fig. 3 is inner core body structural scheme of mechanism.
Reference：Nut body 1, panel beating plate 2, coaxial aperture 3, inner core body 4, card base 5, hole clipping 6, fluting 7, boss 8.
Embodiment
As shown in Figures 1 to 3, the utility model provide it is a kind of have can self-locking function project-welding nut, it includes：Nut
Coaxial aperture 3 on body 1 and panel beating plate 2, and the panel beating plate 2, wherein：It also includes：Connect with the screw thread of nut body 1
The inner core body 4 connect, the lower end of the inner core body 4 has card base 5；And there is hole clipping 6, and the card in the panel beating plate 2
Pin 5 is located in the hole clipping 6.
The utility model is coordinated by card base and hole clipping, and auto-lock function is realized in nut body and inner core body cooperation,
Prevent the superstructure loosening of service stage.
As a further improvement, the inner core body 4 has trapezoidal section, and the upper end of the inner core body 4 is straight
Footpath is less than lower end diameter.
As a further improvement, the fluting 7 from lower end to upper end is disposed with the side wall of the inner core body 4.It is preferred that
, the fluting 7 is wedge shaped.
As a further improvement, the card base 5 has two and arranged along the diameter symmetry of the inner core body 4.Make
For further improvement, the hole clipping 6 has two and arranged along the diameter symmetry of the coaxial aperture 3.
As a further improvement, the end of the card base 5 has the boss 8 protruded inwardly.
In preferred embodiment of the present utility model, the card base 5 of the inner core body 4 is inserted into panel beating plate 2 first
The hole clipping 6 in, then by way of nutting body 1, allow whole project-welding nut to be fixed on metal plate.Pass through card base 5
With the cooperation of hole clipping 6, the auto-lock function of the inner core body 4 in trapezoidal section, and the wedge shaped formation various ways of fluting 7.
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.
