Abstract
The invention discloses a rotary type compression gas spring with automatic reset capacity. The gas spring comprises a cylinder, a piston rod, a seal ring, a check ring and a gas chamber, wherein a fastening groove is formed in the lower part of the cylinder, a lower reset piece is fixed in the fastening groove, an upper reset piece is arranged at the upper part of the lower reset piece and provided with a holding pin to be fixedly connected with the piston rod, and corresponding bilaterally symmetrical helicoids are arranged on the upper surface of the lower reset piece and the lower surface of the upper reset piece. The rotary type compression gas spring has the benefits that the lower reset piece and the upper reset piece which are provided with the corresponding bilaterally symmetrical helicoids are arranged in the cylinder of the compression gas spring in the prior art, so that when the compression gas spring is mounted on an office chair or a chair in a meeting room, the compression gas spring can be in a rotating state and reset automatically after a seat cushion rotates for a certain angle.
Description
Technical field
The present invention relates to a kind of compression type air spring, specifically, is a kind of rotary automatically reset compression type air spring.
Background technique
Compression type air spring mainly plays a supportive role, and is widely used for Office seating and meeting room chair, plays the Main Function of connection seat pad pallet, lower link Foot of chair.The compression type air spring of prior art, is comprised of cylinder body, piston rod, seal ring, back-up ring, air chamber.When needing the height of adjusting seat, the gas that can discharge in air chamber can carry out.Deficiency is: Office seating or the meeting room chair of the compression type air spring of prior art have been installed, after seat cushion has rotated angle, can not have been automatically reset.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of can the automatically reset rotary compression type air spring that automatically resets.
The technological scheme of the rotary automatically reset compression type air spring of the present invention, comprising described in the compression type air spring being comprised of cylinder body, piston rod, seal ring, back-up ring, air chamber that the bottom of cylinder body is provided with binding groove is fixed wtih lower return unit, the top of described lower return unit is provided with return unit, described upper return unit is provided with fixed pin and piston rod is fixedly connected, and the upper surface of described lower return unit and the lower surface of upper return unit are provided with corresponding symmetrical helicoid.
The beneficial effect of the rotary automatically reset compression type air spring of the present invention is, in the cylinder body of prior art compression type air spring, lower return unit and the upper return unit with corresponding symmetrical helicoid is set.Be arranged on Office seating or meeting room chair, after seat cushion has rotated angle, can become rotation status to automatically reset.
Accompanying drawing explanation
Fig. 1 is the plan view of the rotary automatically reset compression type air spring of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is schematic diagram when upper return unit Rotate 180 is spent in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the rotary automatically reset compression type air spring of the present invention is elaborated.
The compression type air spring that automatic rotation shown in Fig. 1, Fig. 2, Fig. 3 resets, comprise the compression type air spring being formed by cylinder body 4, piston rod 1, seal ring 7, back-up ring 8, air chamber 9, the bottom of described cylinder body 4 is provided with binding groove 3 and is fixed wtih lower return unit 2, the top of described lower return unit 2 is provided with return unit 6, described upper return unit 6 is provided with fixed pin 5 and is fixedly connected with piston rod 1, and the lower surface of the upper surface of described lower return unit 2 and upper return unit 6 is provided with corresponding symmetrical helicoid 10.
During installation, the upper end portion of cylinder body 4 in the rotary automatically reset compression type air spring of the present invention and the seat cushion pallet of Office seating or meeting room chair are fixedly connected, the underpart of piston rod 1 and Foot of chair are fixedly connected.In the process of using, after the seat cushion of seat has rotated angle, the pressurized air in air chamber 9 promotes upper return unit 6 downwards, and corresponding, the symmetrical helicoid by lower reset 2 and upper return unit 6 coordinates realizes rotation automatic resetting.
