Description

A kind of two-part seat pillar

Technical field

The utility model belongs to technical field of a vehicle accessory, more particularly, to two-part seat pillar.

Background technology

Most seat pillars in industry are all one-part forms at present, can not adjust the length available of seat pillar.Such as Fig. 1 Shown, same vehicle dimension, 7 length of middle pipe is certain.When seat pipe is inserted into middle pipe bottommost, can not be further continued for inserting, The most short person group that this limit is exactly the lowest limit of seat pipe and the size car is suitble to.It is past inside seat pipe insertion middle pipe On pull out after, stay in seat bar inside middle pipe there are one minimum value, this value is fixed, is 2.5 times of seat pipe diameter, also It is to say that seat bar pulls out cannot pull out outward again in so far.This value is exactly the highest crowd that the car is suitble to.So The now in industry mode of a seat bar, the height of corresponding suitable crowd is fixed, without the record of two sections of seat pipes designs.

Utility model content

The defects of the utility model is intended to overcome the prior art provides a kind of two-part seat pillar, using two sections of seat bars, The highest crowd of adaptation can be improved, increases the range of the suitable crowd of same trolley.After using two-part, can exist The problem of relative rotation, the only design of groove solve the problems, such as relative rotation.

In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：

A kind of two-part seat pillar including seat cushion 1, seat pillar 2, extension rod 3, gasket 4, hanging screw 5, hangs tight fickle in love 6, It is characterized in that：The downside of seat cushion 1 is fixed to be plugged with seat pillar 2, and 2 lower end of seat pillar is fixedly connected with extension rod 3, in extension rod 3 Through there is a hanging screw 5,5 lower part of hanging screw is socketed with gasket 4, snaps onto extension rod bottom on the outside of gasket, hang tight spiral shell in portion Bar upper socket hangs tight fickle in love 6, hangs tight 6 outside fickle in love fixation and is connected in seat pillar.

Further, 2 middle and lower part of seat pillar offers multiple circumferential apertures.

Further, 2 bottom of seat pillar offers seat pillar rotation stop groove 21.

Further, extension rod top also is provided with and the corresponding extension rod groove 31 of seat pillar rotation stop groove.

Further, it is back-off structure to hang tight fickle in love, and hanging tight inside fickle in love has tooth pit.

Compared with prior art, the utility model has following advantageous effect：

The utility model obtains good result simple and reliable for structure, at low cost, safe.(1) two-part seat cushion Rod structure increases seat pillar overall adjustment length.(2) extension rod with seat pillar main body combination, with the side of hanging screw Formula fixes extension rod, prevents two sections of seat bars from relatively rotating with the mode of seat pillar rotation stop groove.Increase seat pillar and adjust height, so as to Increase adapts to crowd's height ranges of same size car.
