Abstract
A chair height adjuster is mainly composed of a fixing muffle, a spring and a movable rod, wherein the spring is fixed at one end of the fixing muffle, the movable rod is movably arranged in the fixing muffle above the spring, while the fixing muffle is provided with a positioning pin which can pass through the wall of the fixing muffle, the movable rod relative to the positioning pin is arranged with a row of plug holes along the axis outer wall of rod. Compared with prior art, the utility model has simple structure, high positioning reliability and long service life.
Description
Technical field:
The utility model relates to a kind of seat component, particularly the seat governor motion.
Background technology:
The governor motion of existing adjusting seat height mainly is made of cylinder, the spring, the valving that are arranged in the cylinder, the bearing down on one piston of cylinder of spring.During use, open the valve of cylinder by valving, at this moment, the spring roof pressure steam-cylinder piston and is moved outward toward cylinder, and the cushion of the seat that will link together with it or backrest raise or be stretched over the position of setting, valve-off then, like this, just the fixed-site of cushion or backrest is got off.When need reducing Chain cushion and packing up backrest, open valve, firmly force down cushion or pack up backrest to the desired location again valve-off get final product.This kind seat with height adjusting mechanism owing to adopt cylinder to locate, and the sealing property of cylinder has determined the reliability of its location, the fact is increasing along with access times, the wearing and tearing of cylinder seal and after causing cylinder gas leakage, the positioning function of cylinder will be lost, and has influenced the normal use of seat.
Summary of the invention:
It is a kind of simple in structure that goal of the invention of the present utility model is to provide, the reliability of positioning height of governor motion, non-damageable seat height adjusting mechanism.
The utility model is to realize like this, mainly by fixedly bobbin, spring, motion bar constitute, spring is fixed on a fixedly end of bobbin, motion bar is movably arranged in the fixedly bobbin above the spring, be provided with alignment pin on the fixedly bobbin on spring, the penetrable stationary magazine creel tube wall of alignment pin, the axis outer wall of the motion bar upper edge bar of corresponding alignment pin is provided with a socket hole.During use, with the standing part of seat such as seat support and fixedly bobbin couple together, the variable partition of seat such as cushion and motion bar are coupled together, also can with cushion and fixedly bobbin couple together, adjustable backrest and motion bar are coupled together, alignment pin is inserted to default position in the position of regulating motion bar then, makes alignment pin run through fixedly bobbin and motion bar, like this, just, simultaneously, also the high and low position of cushion or the fixed-site of backrest are got off the fixed-site of motion bar.
Here, operation also is provided with an alignment pin shifting lever for convenience, and the effect end and the alignment pin of alignment pin shifting lever couple together, and also are provided with a spring on the alignment pin, and the effect of spring is that alignment pin is pressed in the jack of motion bar.During use, by the alignment pin shifting lever alignment pin is taken out from the socket on the motion bar, motion bar can be moved along fixedly bobbin is interior, be convenient for people to cushion or backrest are regulated, after the set positions of cushion or backrest, unclamp the alignment pin poke rod, alignment pin is pressed in the jack of motion bar the fixed-site with motion bar under the effect of spring.
The utility model compared with the prior art owing to adopted alignment pin, thus have simple in structure, the reliability of positioning height of governor motion, non-damageable advantage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model is mainly by fixedly bobbin 1, spring 2, motion bar 3 constitute, spring 2 is fixed on a fixedly end of bobbin 1, motion bar 3 is movably arranged in the fixedly bobbin 1 above the spring 2, be provided with alignment pin 4 on the fixedly bobbin 1 on spring 2, the wall of alignment pin 4 penetrable fixedly bobbins 1, the axis outer wall of the motion bar 3 upper edge bars of corresponding alignment pin 4 is provided with a socket hole 5.Fixedly also be provided with an alignment pin shifting lever 6 on the bobbin 1, the fulcrum of alignment pin shifting lever 6 is connected on the support 7 of fixing bobbin 1, the effect end and the alignment pin 4 of alignment pin shifting lever 6 couple together, be provided with location key seat 8 being provided with on the fixedly bobbin 1 of alignment pin 4, be provided with spring 9 at location key seat 8 and 4 of alignment pins, the effect of spring 9 is that alignment pin 4 is pressed in the jack 5 of motion bar 3.
