Abstract

The utility model provides a spring pressure rod for an automatic convolution return chair. The spring pressure rod comprises an outer pipe and an inner pipe which are mutually nested, wherein a bearing is fixed at one end of the outer pipe, the inner pipe is nested with the other end of the outer pipe, a spring is arranged between the bearing and the inner pipe, and the inner pipe is provided with a cam group which is connected with the spring. The spring pressure rod for the automatic convolution return chair, provided by the utility model, realizes the automatic convolution return of the chair through a reasonable design of the structure of the pressure rod; the automatic convolution return chair can rotate leftwards and rightwards when people sit in the chair, and can automatically return to an original direction and an original height when the people leave the chair.

Description

A kind of auto back cycle position seat spring air pressure rod

Technical field

The utility model relates to a kind of lifting seat air pressure rod, specifically a kind of lifting seat air pressure rod that can auto back cycle position.

Background technology

At present, lifting seat generally all adopts air pressure rod to realize lifting, adjusts function highly.Common air pressure rod product is arranged on above chair, can only height up and down, there is no the function of convolution automatically.After people leaves, seat is fixed on differing heights, very irregular, the lifting seat using especially in public places, and usage quantity is large, frequency of utilization is high, needs manual adjustments height, realizes seat convolution return, wastes time and energy.

Utility model content

The shortcoming existing for prior art is with not enough, technical problem to be solved in the utility model is, a kind of auto back cycle position seat spring air pressure rod is provided, by being set in air pressure rod, the structural design of spring and cam set realizes seat auto back cycle position, when people is sitting in above, can left rotation and right rotation, when people leaves after seat, seat can self-return to original direction and height.

For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of auto back cycle position seat spring air pressure rod, and it comprises mutually nested outer tube and inner tube; Described outer tube one end rigid bearing, the nested inner tube of the other end, arranges spring between bearing and inner tube; Described inner tube arranges cam set and is connected with spring.

Above-mentioned auto back cycle position seat spring air pressure rod, its cam set comprises overhead cam and lower cam, between overhead cam and lower cam, by inclined-plane, coordinates, lower cam is connected with spring.

Above-mentioned auto back cycle position seat spring air pressure rod, multi-stage stairs and spring pin that its overhead cam outer wall setting cooperatively interacts.

Above-mentioned auto back cycle position seat spring air pressure rod, its outer tube arranges outer tube supporting pad rigid bearing, and bearing both sides arrange bearings pad.

Above-mentioned auto back cycle position seat spring air pressure rod, arranges annular brace cover between the outer tube that it is mutually nested and the tube wall of inner tube.

The utlity model has following advantage and useful technique effect:

1, auto back cycle of the present utility model position seat spring air pressure rod, the appropriate design of the structure by air pressure rod realizes seat auto back cycle position, when people is sitting in above, and can left rotation and right rotation, when people leaves after seat, seat can arrive original direction and height by self-return.

2, auto back cycle of the present utility model position seat spring air pressure rod, simple for structure, good looking appearance, practical, be suitable for various lifting seats, especially on the seat of the large-scale public places such as meeting room, amusement arcade, use, uniform, be convenient to maintenance and management.

3, auto back cycle of the present utility model position seat spring air pressure rod, easy to use, time saving and energy saving.
