[Field of Invention]

The present invention relates to a mounting structure of a spring nut used in an automobile assembly line, and more particularly, to prevent the spring nut from rotating on the mounting surface of the vehicle body when the spring nut is mounted on the vehicle body by a screw. The spring nut mounting structure of the vehicle body.

[Prior art]

In general, a variety of coupling means such as bolts, nuts, rivets, clips, grommet, etc. are used in the assembling process of the vehicle, and the coupling means is appropriately selected according to the mounting portion and the application.

On the other hand, one of the coupling means is a spring nut (spring nut), the spring nut is made of a spring steel plate, although the thickness of one screw of the screw, but if the screw is coupled to the spring nut screw by the reaction force of the spring steel plate It is effective to prevent loosening.

In FIG. 1, the mounting structure of the spring nut 1 is shown in an exploded perspective view in the related art. As shown in the drawing, the spring nut 1 is made of two layers by folding a single layer of spring steel plate and overlapped with each other. The through hole 2 for coupling the screw 6 is formed in the center of the surface, and the mounting surface 3 of the vehicle body on which the spring nut 1 is mounted is cut in a predetermined thickness of the vehicle body. A groove 4 cut out from the end is formed, and the step 5 formed by cutting the thickness of the mounting surface 3 is formed to be inclined.

2 is a cross-sectional view of the spring nut 1 of FIG. 1 mounted on the mounting surface 3, and as shown, the spring nut 1 is mounted between two spring steel plates. The spring nut 1 is attached by screwing the screw 6 through the hole 2 formed in the center of the steel plate and the groove 4 of the mounting surface 3 while the surface 3 is fitted.

[Technical problem to be achieved]

By the way, in the mounting structure of the conventional spring nut 1, since the step portion 5 on the mounting surface 3 on which the spring nut 1 is mounted is formed to be inclined, the spring nut 1 If the screw is not properly coupled during installation, the spring nut 1 is rotated about the screw 6 to rise along the inclined surface of the stepped portion 5, thereby causing the spring nut to be damaged.

Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to prevent the spring nut from rotating about a screw by improving the mounting structure of the spring nut.

[Configuration and Function of Invention]

In order to achieve this object, the present invention is to fold a single layer of spring steel plate made of two layers, the spring nut having a through hole for screwing is formed in the center of the overlapping surface; The spring nut is mounted, and further includes a mounting surface formed with a groove formed from the end of the spring nut, the spring nut is the center of the steel sheet in a state that the mounting surface of the vehicle body is sandwiched between the two-layered spring steel sheet In the spring nut mounting structure of a vehicle body which is mounted by screwing through a hole formed in a hole and a mounting surface, an approximately c-shaped stop portion is formed around a groove formed in the mounting surface on which the spring nut is mounted. Thus, when the spring nut is rotated about the screw on the mounting surface after the spring nut is mounted on the mounting surface, the rotation is prevented by a stop formed around the groove.

In addition, since the rotation of the spring nut mounted on the mounting surface of the vehicle body is prevented by the stopper, it is preferable that the spring nut is prevented from rotating together with the rotation of the screw even when the spring nut is mounted.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In this embodiment, the same reference numerals are assigned to the same parts as those cited in the related art, and will be described again to avoid duplication of description. I never do that.

3 is an exploded perspective view showing the mounting structure of the vehicle body and the spring nut 1 according to the present invention. According to the present invention, the mounting surface 3 of the vehicle body on which the spring nut 1 is mounted is shown in FIG. Does not form a stepped portion 5, such as a spring nut on the mounting surface, instead of forming a substantially c-shaped stop 7 around the groove 4 formed on the mounting surface 3 When the spring nut 1 is rotated about the screw 6 on the mounting surface 3 after (1) is mounted, it is rotated by the stop 7 formed around the groove 4. This will be blocked.

Thus, as shown in the sectional view in FIG. 4, the rotation of the spring nut 1 mounted on the mounting surface 3 of the vehicle body is prevented by the stopper 7, whereby the mounting of the spring nut 1 is performed. Even when the spring nut 1 is prevented from rotating along with the rotation of the screw.

[Effects of the Invention]

As described above, according to the mounting structure of the spring nut according to the present invention, the spring nut is provided around the groove of the mounting surface on which the spring nut is mounted, thereby providing a stop functioning as a barrier for preventing rotation of the spring nut. It is effective to prevent the rotation of the spring nut due to poor screwing or external force during as well as after installation.

The present invention has been illustrated and described above with respect to certain preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention belongs without departing from the spirit of the invention as claimed in the claims. Anyone with ordinary knowledge in the field may make various changes.
