Abstract
The utility model discloses seat slide plate bolt, formed by metal wire rod cold-heading, include the threaded portion and shaft portion of connection, it is characterised in that：The first axostylus axostyle that shaft portion is increased successively by diameter, second axostylus axostyle, 3rd axostylus axostyle and the 4th axostylus axostyle are formed, first, second, third and fourth axostylus axostyle is the cylinder body of rod, first axostylus axostyle connecting thread portion point, second, the left and right sides of the cylinder body of rod of 3rd axostylus axostyle goes out symmetrical first by cold-heading, second plane, the left and right sides of the cylinder body of rod of 4th axostylus axostyle goes out the symmetrical 3rd by cold-heading, fourth plane, first, the bar footpath that the distance between second plane is more than the first axostylus axostyle is 1.2 1.6mm, 3rd, the distance between fourth plane is more than first, the distance between second plane is 1.4 1.8mm.The utility model can ensure more preferably to be connected and be connected with the screw-thread securing of seat support with riveting tightly for seat slide plate, saving material rational in infrastructure, and technique is simple.
Description
Technical field
It the utility model is related to a kind of automotive seat part, and in particular to a kind of seat slide plate bolt.
Background technology
Automotive seat can carry out the slidable adjustment of fore-and-aft direction, and automotive seat part includes a seat slide plate bolt, seat
Chair slide plate bolt with seat slide plate should rivet tightly being connected and is connected again with seat support progress screw-thread securing, still, due to
The seat slide plate bolt of prior art is typically using machining, and milling cutter can be in the whole of seat slide plate bolt shaft portion during machining
Individual axial left and right side mills out integral planar, and such seat slide plate bolt is loading corresponding to seat slide plate in riveted holes
When, axostylus axostyle only root not by integral planar milling to partial circle and seat slide plate between form riveting, riveting is strong
Degree is weaker, and long-term use is just also easy to produce loosening.Equally, the seat slide plate bolt of prior art, the screw thread between seat support
Connection is fastened nor especially reliable.
The content of the invention
In view of insufficient existing for background technology, the purpose of this utility model, which is intended to provide one kind, can ensure more preferably and seat
Riveting tightly for slide plate is connected and is connected with the screw-thread securing of seat support, saving material rational in infrastructure, the simple seat slide plate of technique
Bolt.
The utility model is implemented by following technical solution：
Seat slide plate bolt, is formed by metal wire rod cold-heading, includes the threaded portion and shaft portion of connection, and its feature exists
In：The first axostylus axostyle, the second axostylus axostyle, the 3rd axostylus axostyle and the 4th axostylus axostyle that shaft portion is increased successively by diameter are formed, and first,
2nd, the third and fourth axostylus axostyle is the cylinder body of rod, and the first axostylus axostyle connecting thread portion divides, the cylinder body of rod of second, third axostylus axostyle
The left and right sides goes out symmetrical first, second plane by cold-heading, and the left and right sides of the cylinder body of rod of the 4th axostylus axostyle is gone out symmetrically by cold-heading
The 3rd, to be more than the bar footpath of the first axostylus axostyle be 1.2-1.6mm to the distance between fourth plane, first, second plane, the 3rd, the
It is 1.4-1.8mm that the distance between four planes, which are more than the distance between first, second plane,.
Second axostylus axostyle, the bar footpath difference of the 3rd axostylus axostyle are 1.1-1.5mm.
The end of threaded portion is provided with polished rod and sets flat recess in the end face middle position of polished rod.
After adopting the above technical scheme, seat slide plate bolt is metal cold-heading part, it is important that the left and right sides of the 4th axostylus axostyle
Face is not by first, second plane（Integral planar of first, second plane equivalent to prior art）Run through, such seat
The riveting that slide plate can be formed in whole circumference in the root of the 3rd axostylus axostyle, riveting intensity high reliability is good, therefore for a long time
Using not loosening guarantee quality.In addition, the relative dimensions control of each part of seat slide plate bolt, makes saving material rational in infrastructure
Material, technique are simple.Further, the polished rod end face of threaded portion end sets flat recess, polished rod end face is not produced in middle position
Raw local crowning, leaning between such seat slide plate bolt and other parts, which can just keep stable, will not tilt stress,
The more preferable screw-thread securing quality of connection for ensureing seat slide plate bolt and seat support.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is shape assumption diagram of the present utility model,
Fig. 2 looks up directional diagram for Fig. 1's.
Embodiment
As illustrated, seat slide plate bolt of the present utility model, is formed for metal cold-heading part by metal wire rod cold-heading, including
The threaded portion 5 and shaft portion of connection, the first axostylus axostyle 4 that shaft portion is increased successively by diameter, the second axostylus axostyle 3, the 3rd axle
The axostylus axostyle 1 of bar 2 and the 4th is formed, and first, second, third and fourth axostylus axostyle is the cylinder body of rod, the connection screw thread part of the first axostylus axostyle 4
5, the left and right sides of the cylinder body of rod of second, third axostylus axostyle goes out symmetrical first plane 81, the second plane 82, the second axle by cold-heading
Bar, the bar footpath difference of the 3rd axostylus axostyle are 1.1-1.5mm, and the left and right sides of the cylinder body of rod of the 4th axostylus axostyle 1 goes out symmetrical by cold-heading
The bar footpath that three planes 91, the distance between fourth plane 92, first, second plane are more than the first axostylus axostyle 4 is 1.2-1.6mm, the
3rd, it is 1.4-1.8mm that the distance between fourth plane, which is more than the distance between first, second plane, and the end of threaded portion 5 is set
There is polished rod 6 and flat recess 7 is set in the end face middle position of polished rod 6.
Above-mentioned seat slide plate bolt is riveted tightly with seat slide plate when being connected, between the riveted holes of seat slide plate and the 3rd axostylus axostyle 2
Gap coordinates and riveted holes under shed end face is bonded with the 4th axostylus axostyle inner side end A, and such seat slide plate can be in the 3rd axostylus axostyle 2
The riveting that is formed in whole circumference of root, riveting intensity high reliability is good.
