Description

Embedded riveting column

Technical Field

The utility model relates to a module power field, concretely relates to embedded riveting post.

Background

The module power adopts traditional welding or finish milling when the installation is fixed more, and the welding has the limitation when having the application occasion of space requirement to the product to in the finish milling structural design quantity more, and the finish milling structure also adopts the mode of riveting the post through soldering tin welding on aluminium base board when specifically installing outwards extends the mounted position, so that to the installation of whole module power.

However, the existing riveting column structure can only be fixed on an aluminum substrate of a module power supply in a welding mode, and the situation that the riveting column is loosened after the riveting column structure is subjected to the action of external force in the using process is caused.

SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides an embedded riveting post has solved current riveting post structure and has passed through welded mounting on the module power, the easy not hard up problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an embedded riveting column comprises a column body, wherein a first step and a second step are arranged at one end of the column body, the outer diameters of the first step and the second step are sequentially reduced from inside to outside, and a third step is arranged at the other end of the column body; the second step is provided with anti-skid flower teeth which are uniformly distributed along the circumferential direction; the column body is provided with a threaded hole which is communicated along the axial direction.

Preferably, an anti-disengagement clamping groove is arranged between the first step and the second step.

Preferably, the anti-dropping-out clamping groove is of a tapered groove structure inclined from the second step to the first step.

Preferably, the width of the anti-falling-out clamping groove is greater than that of the first step.

Preferably, the embedded riveting column is of an integrated structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

the riveting carrier is positioned through the second step, the riveting carrier is extruded and deformed between the first step and the second step and clamped tightly under the extrusion action of the first step, and meanwhile, the deformation position is further limited through the anti-skidding spline teeth in the deformation process of the riveting carrier, so that the whole riveting column is more stably connected with the riveting carrier into a whole; and adopt the mode of deformation chucking can guarantee also can avoid the not hard up condition of riveting post in long-time use.

FIG. 2 is a schematic sectional view A-A of FIG. 1;

FIG. 3 is a side view of the structure of FIG. 1;

in the figure, a column body 1, a first step 2, a second step 3, a third step 4, anti-skid flower teeth 5, a threaded hole 6 and an anti-falling clamping groove 7.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 to 3, the utility model provides an embedded rivet column, which comprises a column body 1, wherein one end of the column body 1 is provided with a first step 2 and a second step 3, the outer diameters of which are sequentially reduced from inside to outside, and the width of the second step 3 is larger than that of the first step 2; a third step 4 is arranged at the other end of the column body 1; anti-skid flower teeth 5 uniformly distributed along the circumferential direction are arranged on the second step 3; during riveting, the riveting carrier is positioned through the second step 3, and meanwhile, after the riveting carrier is limited through the second step 3, the riveting carrier can be tightly pressed between the first step 2 and the second step 3 when being extruded, and the deformed riveting carrier is limited and clamped through the anti-skidding spline teeth 5, so that the tight connection stability is further improved; after the whole riveting column is fixed on an aluminum substrate of the module power supply, the guiding and positioning are carried out through the third step 4 during installation and use, and in order to lock the riveting column, the threaded hole 6 which is through along the axial direction is formed in the column body 1, so that the whole module power supply can be locked and installed through the matching of the threaded hole 6 and the locking screw when being installed.

In order to further improve the riveting stability in the state that the riveting carrier is extruded and deformed between the first step 2 and the second step 3 and is limited on the anti-slip spline 5, an anti-falling clamping groove 7 is arranged between the first step 2 and the second step 3, so that the riveting carrier can clamp the deformed edge position into the anti-falling clamping groove 7 after being extruded, and the whole riveting column can be more effectively prevented from being loosened under the condition of external force; simultaneously, let anticreep play draw-in groove 7 be from the second step 3 to the taper shaped groove structure of the 2 slopes of first step for the riveting carrier edge pressurized is followed and is scratched in preventing deviating from draw-in groove 7, and receives tapered limiting displacement of taper shaped groove and strengthen the anticreep effect.

More riveting carrier positions in the anti-disengagement clamping groove 7 are clamped, riveting is more stable, and the width of the anti-disengagement clamping groove 7 is larger than that of the first step 2.

Meanwhile, in order to facilitate processing, the whole embedded riveting column is of an integrated structure, and after the first step 2, the second step 3 and the third step 4 are processed, the anti-skid spline teeth 5 are processed on the first step 2.

In the explanation of the present invention, it should be noted that the terms "first", "second", "third", and the like are only used for convenience of description and understanding, and do not limit the number, importance degree, or sequence of the specific technical features.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
