Abstract

The utility model relates to a nut column, which comprises a base and a column body vertically connected to the base, wherein the column body forms a cylinder shape, and the axial direction of the column body is hollow to form an annular side wall, the inner surface of which is provided with internal threads; one end on the outer surface of the side wall far away from the base is provided with a projecting part which is outward projected along the radial direction; the projecting part can be an annular rib which forms a smooth blend with the outer surface, and the middle diameter of the rib is large and the diameters of both sides are small; the projecting part can also be a projected block provided with a triangle, and the diameter of the projected block is gradually increased from the top end to bottom.

Description

Nut column

Technical field

The utility model relates to a kind of Nut column, relates in particular to the Nut column on a kind of through hole that can be buckled in sheet material.

Background technique

Now, computer has become requisite assistant and instrument in people's work and the life.Be assembled with CPU on the host board of computer, in order to help the CPU heat radiation, top installing radiator and the fan of CPU.In order to fix this fan, generally on this host board, offer several through holes.A backboard is adorned at the back side of dress CPU one side on this host board, is fixed with several Nut columns on this backboard, and these Nut column axis directions are hollow, and its inwall is offered internal thread.Some Nut columns of this backboard are inserted in these several through holes, and the bolt by in some internal threads that are screwed to this Nut column is connected to this fan on this radiator.Yet, because the general up and down thickness of the outer wall of this Nut column, when bolt is not screwed on this internal thread, because this Nut column of effect of gravity is easy to drop out from this through hole, must be again the Nut column of backboard be inserted in the through hole again and could assembles fan, so not only troublesome poeration, and the assembling speed of the fan that slowed down.

Summary of the invention

The purpose of this utility model is to provide a kind of Nut column, and it can be buckled on the through hole of sheet material, thus assembling that can be more convenient.

For achieving the above object, the utility model provides a kind of Nut column, and it comprises a post body, and this post body shaft is to being the hollow sidewall that forms an annular, offer an internal thread on its inside surface of side wall, the outer surface of this sidewall is provided with the bump of outside protrusion.

This Nut column is loaded on the radiation fan of interlocking CPU on the host board of computer, offer some through holes near the CPU of this host board, be provided with at this host board on the back side of CPU one side and be provided with a backboard, these several above-mentioned Nut columns of backboard upper punch press fit, corresponding these through holes of these Nut columns.

The utlity model has following beneficial effect: these bumps of this nut retainer squeeze in through hole and to increase frictional force or pass these through holes and be exposed at the another side of host board, can prevent from therefore that Nut column from coming off to drop out from through hole.The bolt that wears passing through fan is screwed in the internal thread of this nut retainer, so far fan just stably is fixed on this cpu heat.Such structure makes simple and convenient assembly, has improved the fan assembling speed.

Embodiment

See also Fig. 1 to Fig. 3, a kind of Nut column 8, it comprises that a base 1 and is vertically connected at the post body 2 on this base 1.This post body 2 is the cylinder bodily form, and it axially is the hollow sidewall that forms an annular 20, offers an internal thread 22 on the internal surface of its sidewall 20, and the end away from this base 1 is provided with a bump 24 that radially outwards protrudes on the outer surface of sidewall 20.

This bump 24 can be fin 26 (see figure 1)s with the annular of outer surface rounding off, and these fin 26 mid diameters are big and the both sides diameter is little.This bump 24 also can increase from the downward diameter in its top gradually for a projection 28 (seeing figure two) with triangle.

This Nut column 8 is loaded on the radiation fan (figure does not show) of host board (figure does not show) the interlocking CPU that comes up of computer.Offer some through holes (figure does not show) near the CPU of this host board.Be provided with at this host board on the back side of CPU one side and be provided with a backboard 3.These several above-mentioned Nut columns 8 of backboard 3 upper punch press fit, these Nut column 8 corresponding these through holes.

During the assembling fan, earlier Nut column 8 correspondences are snapped in these through holes, because have bump 24 on these Nut columns 8, these bumps 24 squeeze in through hole and to increase frictional force or pass these through holes and be exposed at the another side of host board, can prevent from therefore that Nut column 8 from coming off to drop out from through hole.This backboard 3 is fixed on this host board.The bolt (figure does not show) that wears passing through fan is screwed in the internal thread 22 of this nut retainer 8, and so far fan just stably is fixed on this cpu heat (figure does not show).

More than be first embodiment of the present utility model, as variant embodiment of the present utility model, post body in the utility model can be other outer shapes of cylindrical body shape, and such as the square column bodily form, triangle bodily form or the like, the shape of respective through hole should cooperate the shape of post body.

The shape of bump in first embodiment, enumerate can also be other shapes, can be circular arc line such as above-mentioned hypotenuse instead, perhaps above-mentioned bump is not continuous annular, and can be the annular the disconnection form.

The height and position of bump is except only being provided with the bump at the end away from this base described in first embodiment, can also be provided with bump on the different heights on the outer surface of sidewall, for example highest point is established a bump, and also establishes a bump at the intermediate altitude place.

Be not limited only to first embodiment's computer main frame panel for the use occasion of this Nut column, in fact, all can be on any tabular material at a side loading nut post, opposite side is installed this occasion of an assembly to the opposite side of board-like material by the internal thread of Nut column, can use Nut column of the present utility model.
