Abstract

A chair lifting controller with convenient use and adjustment is provided with a cylinder (4) on the upper end of a base (6), wherein, a piston (3) is arranged inside the cylinder (4); a spring (7) is arranged under the piston; an air door (2) is arranged on the upper end of the piston; a pin shaft (14) crosses within a tray (1) formed between the upper end of the piston and a chair plane; a lever (13) penetrating the pin shaft is arranged inside the tray; the front end of the lever abuts against the upper end of the air door (2); a roller shaft which is sheathed by a roller (12) is arranged on the back end of the lever; a cable (10) winding around the roller has one end passing through a cable hole (8) on the side face of the tray and being connected with a handle (9) out of the tray and the other end being fixed on the upper bottom surface of the tray. The utility model is suitable as a chair lifting controller capable of facilitating up and down adjustment of the chair plane.

Description

The seat lifting controller

Technical field

The utility model relates to a kind of seat adjuster.

Background technology

Liftable is regulated a kind of seat of seat height in the prior art, the seat lift adjustment adopts the method for spring pneumaticpiston to realize mostly, be provided with a valve on the top of piston, valve is controlled by proficiency dynamic pressure bar, its weak point is: depression bar needs the bottom that certain length section is exposed to seat, not only sense organ is poor, and also waste material causes production cost to increase.

Summary of the invention

It is easy to adjust that technical problem to be solved in the utility model provides a kind of use, economical with materials, and sense organ is good, the seat lifting controller that production cost is lower.

For solving the problems of the technologies described above, the technical solution adopted in the utility model comprises cylinder and interior set piston and the spring of being located at the base upper end, the piston upper end is provided with valve, its special character is that piston pallet interior span that the upper end joins connection is fixed with a bearing pin, be equipped with lever on the bearing pin and be positioned at pallet, the lever front end is resisted against the valve upper end, lever rear end is fixed with roller shaft and is with roller on it, be tied with cable wire on the roller, cable wire one end is connected with handle and is positioned at outside the pallet, and the cable wire other end is fixed in the pallet.

The described cable wire other end is fixed in and is meant in the pallet that this end of cable wire is fixed in the upper bottom surface in the pallet.

The described cable wire other end is fixed in and can be meant also in the pallet that the pallet interior span is established and be fixed with a pulley spindle and be positioned at pallet top, and this end of cable wire is fixed in pulley spindle; Be with fixed pulley on the pulley spindle, its two ends of described roller shaft are placed in the groove of being offered the pallet both sides, and described cable wire twines in fixed pulley.

The end that cable wire described in the utility model is connected with handle can pass is located at the set cable wire hole of pallet one side.

The utility model is owing to be provided with lever, lever rear end is provided with roller, be tied with cable wire on it, roller is equivalent to movable pulley, so pulling cable wire one end is positioned at the outer handle of pallet, just can makes on the lever rear end and carry, the lever front end is just depressed valve, but just easy adjustment chair surface height, it is equivalent to the existence of the roller of movable pulley, and the power of pulling cable wire is alleviated.

The specific embodiment

Embodiment 1

This routine seat lifting controller, base 6 upper ends are provided with cylinder 4 and are provided with piston 3 in it, be provided with spring 7 below the piston, piston 3 upper ends are provided with valve 2, the pallet 1 interior span connection that is joined between piston 3 upper ends and the seat 15 is fixed with a bearing pin 14, be equipped with lever 13 on the bearing pin 14 and be positioned at pallet 1, lever 13 front ends are resisted against valve 2 upper ends, lever rear end is fixed with roller shaft 11 and is with roller 12 on it, be tied with cable wire 10 on the roller 12, the cable wire hole 8 that cable wire 10 1 ends pass the pallet side is connected with handle 9 and is positioned at outside the pallet 1, and cable wire 10 other ends are fixed in the upper bottom surface in the pallet 1; Cylinder is sheathed with dust protection rubber cover 5 outward.

Embodiment 2

This routine seat lifting controller, pallet 1 interior span are established and are fixed with a pulley spindle 17 and are positioned at pallet 1 top, and the cable wire other end is fixed in pulley spindle 17; Be with fixed pulley 18 on the pulley spindle, its two ends of roller shaft are placed in the groove of offering pallet 1 both sides 16, and cable wire 10 twines in fixed pulley 18.Other structure is identical with last example.
