Specific embodiment
Referring to Fig. 1-Fig. 6, the utility model includes 2 two parts of the upper slide track component 1 being mutually slidably matched and glidepath,
A pair of identical bearing assembly 1, bearing assembly 2 42 and plastic part 1, plastic part two are provided on upper slide track component 1
52 and a roll wheel assembly 6, roll wheel assembly 6 be located on the middle position of upper slide track component 1, bearing assembly 1 and bearing group
Part 2 42 and plastic part 1, plastic part 2 52 be located on the equidistant position of 1 two sides of slide track component, is eliminated with this
The gap of Y-direction and Z-direction.Since this structure is identical as the Chinese utility model patent 2017204398214 that our company applies
Or it is equivalent, it is not repeated to describe herein.
In the present embodiment, plastic part 1, plastic part 2 52 are located at bearing assembly 1, bearing assembly 2 42
Inside.
It is provided with symmetrical screw hole 22 on the glidepath 2 of utility model, is additionally provided with below glidepath 2 with two sides
Fixing piece 3.
In the present embodiment, it is additionally provided with position-limit mechanism 7, which includes caging bolt 71,72 and of Limit screw
Stop nut 73, the both ends of Limit screw 72 are caging bolt 71, and stop nut 73 and caging bolt 71 cooperate, Limit screw 72
Across glidepath 2 sliding-rail groove 23 and matched with the front and rear end of upper slide track component 1 17,18.
The stroke adjustment of the utility model is realized by following scheme；
When sliding rail is in lockup state, lock card 14 is rotated along rotation axis 16 by 15 pulling force of spring, makes the lock on lock card 14
Tooth protrudes into the continuous window 21 of glidepath 2, so that sliding rail is in lockup state, sliding rail can not be adjusted at this time.When occupant uses
Unlock rod pushes lock card 14, and lock card 14 overcomes 15 elastic force of spring, reversely rotates along rotation axis 16, and the lock tooth on lock card 14 is from downslide
It is retracted in the continuous window 21 of rail 2, sliding rail unlock.
When occupant needs to adjust, pull-up operating stick, under sliding rail is in the unlocked state, by bearing assembly 1, bearing group
Part 2 42 is supported on the face of glidepath 2 and rolls.Client can adjust sliding rail stroke according to self-demand, sliding rail is moved to suitable
After answering position, unlock rod is put down, sliding rail is made to be in lockup state.
When sliding rail assembly is in front and back extreme position, across the screw hole 22 of glidepath 2, the bolt 71 of assembly is used in combination
Nut 73 locks, and the screw portion 72 of bolt 71 blocks the front and rear end 17,18 of slide track component 1, plays position-limiting action, prevents
Only upper slide track component 1 goes out glidepath 2.
In use, using nut 1, nut 2 12 and automotive seat after upper slide track component 1 is positioned by positioning pin 13
Skeleton connection；Glidepath 2 is connected by bolt with the vehicle body of automotive seat, and upper slide track component 1 can be the weldering of two panels sheet metal component
It connects, is also possible to independent a piece of sheet metal component.
By foregoing description, those skilled in the art can implement, and the part being not described in is the prior art.
The title that the above components of the utility model are taken can be different, all according to structure described in the concept of the patent of the utility model
It makes, the equivalent or simple change that feature and principle are done, is included in the protection scope of the utility model patent.
