Description
Technical field
The utility model is relevant with seat, and is particularly relevant with the elevating mechanism of armrest.
Background technology
Seat is the utensil that everyone can use every day, especially the people of office work that handles official business, need especially to be sitting on the seat for a long time, the quality of seat can directly influence the impression that the user takes, and because each user's height, build and use habit are neither to the greatest extent identical, except traditional bench height adjustment, the adjustable height handrail is also popularized gradually on handling official business with seat.
The inventor had before had and had developed a kind of armrest lifting structure, be No. the 200620134731.6th, Chinese utility model patent, the structure of this case is mainly upwards to pull a pull handle 33 to drive pull bar 30, make and be arranged in oblique hole 34, screw 422 and pilot pin 40 in comb shape slide opening 23 and the spacing hole 52 can laterally move in the longitudinal hole of slide opening 23 because of the corresponding directive effect of this oblique hole 34 and spacing hole 52, this moment, screw 422 and pilot pin 40 can free slippages in this longitudinal hole, after waiting to move to desired location, can decontrol pull handle 33 makes pull bar 30 be subjected to the ejection of spring 333 and moves down, this moment, screw 422 and pilot pin 40 can be pushed by taking advantage of a situation in the semicircle tooth 221 of location division 22, can form positioning action.
In said structure, adjust function very easily though can reach, but because screw 422 and pilot pin must pass sliding sleeve 50, pull bar 30 and bracing frame 20, and sliding sleeve 50 and bracing frame 20 all have suitable thickness, so screw 422 and pilot pin 40 formed total lengths must be more greater than sliding sleeves 50, the gross thickness of pull bar 30 and bracing frame 20, therefore its length also needs quite long, because the length of screw 422 and pilot pin 40 is longer, and the shape of three holes that it passed through and action are also different separately, very easily when screw 422 and pilot pin 40 move because of the deflection stopper being arranged slightly in a certain hole, it is not very smooth and easy causing the Height Adjustment operation, still has further improved necessity.
The utility model content
The technical problem that the utility model mainly will solve promptly is to provide a kind of seat chair with adjustable handrail supporting construction, and it changes the structure configuration relation, effectively shortens the length of pilot pin, makes the Height Adjustment operation more smooth and easy, is difficult for blocking because of the pilot pin deflection.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
