Description

Technical Field

[0001] The utility model relates to the technical field of pressure riveted nut columns, in particular to an improved pressure riveted nut column. Background Art

[0002] Riveting technology is a processing method that presses one part into another sheet metal part to fix it. By setting mounting holes on the sheet metal and then placing the parts to be riveted into them for processing, the two are connected and fixed together, improving their stability and connection strength.

[0003] The structure of the riveted part at the lower end of the nut column currently on the market is conical, which makes the connection strength between the nut column and the plate not strong enough, and the two are prone to loosening. In addition, the existing nut column can only bear a weight of 6 kilograms, resulting in a limited scope of use.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide an improved self-clinching nut column.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An improved self-riveted nut column comprises a plate and a nut column riveted at the upper end thereof, the nut column comprising a fixing portion and a column body, the column body being arranged at the upper end of the fixing portion, the fixing portion comprising a fixing boss and a riveted end, the fixing boss being arranged between the column body and the riveted end, the diameter of the fixing boss being larger than the diameters of the column body and the riveted end, and an inwardly recessed groove being arranged between the riveted end and the fixing boss.

[0008] As a preference, the fixing boss is provided with teeth grooves, and the annular array of teeth grooves is arranged on the side end surface of the fixing boss to increase the stability of the connection with the plate.

[0009] As a preferred embodiment, an inwardly inclined inner chamfer is provided between the riveting end and the groove.

[0010] As a preference, the height of the fixing boss is set to two fifths of the overall height of the fixing portion.

[0011] As a preference, the height of the riveting end is set to one fifth of the overall height of the fixing portion.

[0012] As a preference, the height of the groove is set to one fifth of the overall height of the fixing portion.

[0013] As a preference, the height distance of the inner chamfer is set to one fifth of the overall height of the fixing portion.

[0014] As a preference, the distance between the innermost end surface of the groove and the outer end surface of the riveting end is set to one fifth of the overall height of the fixing portion.

[0015] As a preferred embodiment, the diameter of the column body is the same as the diameter of the riveted end.

[0016] As a preference, the upper end surface of the column body is provided with a threaded mounting hole extending from top to bottom to the fixing portion.

[0017] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0018] The utility model has a simple structure and is easy to use. By improving the riveting fixing part of the nut column, the connection stability between the nut column and the plate is enhanced, and the weight that can be borne is increased. The lower end of the nut column is set to an equal-proportional structure. Regardless of the size of the diameter of the nut column, the ratio between each layer of the structure is always kept equal, so that the nut column has good structural stability, and can withstand a weight of 12 kilograms after being riveted to the plate. The improved nut column can be used in more environments, can withstand a larger weight and has better connection stability. BRIEF DESCRIPTION OF THE DRAWINGS
