Description
Technical field
The utility model relates to a kind of nut, particularly a kind of insert nut structure of glass-frame riser.
Background technique
Along with the development of automobile industry, auto manufacturing proposes more and more higher requirement to the reliability of auto parts and components.Glass-frame riser is the important composition parts of automobile, for controlling the lifting of automobile door glass.Insert nut is for connecting the heavy connection of glass-frame riser and car door panel beating.Referring to Fig. 5 to Fig. 7, the insert nut of existing glass-frame riser is generally cylindrical nut 1 ', one end of this cylindrical nut 1 ' is stub end 6, the other end is the section of extending axially 7 that diameter is less than stub end 6, the outer surface of the section of extending axially 7 is provided with annular knurl 8, during installation, directly by the section of extending axially of cylindrical nut 7, the mode by integrated injection molding embeds in the roll of plastic wheel seat erection column of glass-frame riser, can complete the assembling of insert nut and roll of plastic wheel seat erection column, thereby conveniently be connected and fixed with car door panel beating.But the deficiency of the insert nut of existing glass-frame riser is, because the degree of depth of the annular knurl 8 of the section of extending axially of cylindrical nut is limited, cause annular knurl 8 limited with the combination of roll of plastic wheel seat erection column, when mounting torque fluctuation is larger, be prone to insert nut and the skidding of reel erection column, cause the installation of glass-frame riser to be lost efficacy; And because the section of the extending axially outer surface annular knurl at cylindrical nut adopts turning process conventionally, make the cost of this insert nut higher, restricting optimization of product cost.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of insert nut structure of glass-frame riser is provided, and it not only can increase the torque resistant ability of insert nut, improves the stability of product, and can reduce costs, be conducive to the cost optimization of product.
The purpose of this utility model is achieved in that and comprises for embedding the cylindrical nut of the reel erection column of glass-frame riser, one end of described cylindrical nut is axle journal, the outer surface of the other end is arranged with four pawls that radially extend along cylindrical nut, and the extending end end face of each pawl is provided with along the axially extended double wedge of cylindrical nut.
The extending end of four pawls is combined into dimetric projection.
The outer surface of one section of described cylindrical nut between adjacent two pawls is plane.
Adopt technique scheme: because one end of cylindrical nut of the present utility model is axle journal, the outer surface of the other end is arranged with four pawls that radially extend along cylindrical nut, the extending end end face of each pawl is provided with along the axially extended double wedge of cylindrical nut, after like this in the reel erection column of insert nut injection moulding embedding glass-frame riser, double wedge on each pawl and each pawl can be combined closely with the inwall of reel erection column, thereby increased the combination degree of depth of insert nut and reel erection column, increased greatly the ability of insert nut opposing moment of torsion, through claimant, test, the ability of existing annular knurl type insert nut opposing moment of torsion is 15N.m to the maximum, the utility model is under same experimental condition, more than the ability of its opposing moment of torsion can be increased to 20N.m, the ability of opposing moment of torsion has improved more than 30%, met the requirement of main engine factory to glass-frame riser mounting torque.
The utility model adopts cold heading technique machine shaping, compares with the annular knurl type insert nut of existing employing turning process, in cost of parts, by original 0.32 yuan, is down to 0.17 yuan, and the range of decrease, up to 46.8%, has reached the object reducing costs.
The insert nut structure of the utility model glass-frame riser, not only can increase the torque resistant ability of insert nut, improves the stability of product, and can reduce costs, and is conducive to the cost optimization of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Fig. 3 is schematic perspective view of the present utility model;

In accompanying drawing, 1,1 ' is cylindrical nut, and 1a is plane, and 2 is axle journal, and 3 is pawl, and 4 is double wedge, and 5 is reel erection column, and 6 is stub end, and 7 is the section of extending axially, and 8 is annular knurl.
Embodiment
Referring to Fig. 1 to Fig. 4, a kind of embodiment of the insert nut structure of glass-frame riser, this structure comprises for embedding the cylindrical nut 1 of the reel erection column 5 of glass-frame riser, in the present embodiment, the height of cylindrical nut 1 is 5.5～6.5mm, cylindrical nut 1 adopts cold heading technique machine shaping, cylindrical nut 1 and 5 molding and forming of reel erection column.One end of described cylindrical nut 1 is axle journal 2, the outer surface of the other end is arranged with four pawls 3 that radially extend along cylindrical nut 1, the extending end of four pawls 3 is combined into dimetric projection, in the present embodiment, the length of side of this dimetric projection is 11～12mm, the extending end end face of each pawl 3 is provided with along the axially extended double wedge 4 of cylindrical nut 1, after making like this cylindrical nut 1 embed in reel erection column 5, can be by the double wedge 4 on four pawls 3 and four pawls, increase the combination degree of depth of cylindrical nut 1 and reel erection column 5, increased greatly the ability of whole cylindrical nut 1 opposing moment of torsion, to improve the stability of product.
