Office chair capable of relieving leg fatigue based on reciprocating motion

Abstract

The invention relates to the technical field of office chairs, and discloses an office chair capable of relieving leg fatigue based on reciprocating motion. The office chair comprises a chair seat, wherein the lower end of the chair seat is fixedly provided with a support frame, the inner cavity of the support frame is fixedly connected with a hinge frame, the hinge frame is provided with a telescopic rod, the left end of the hinge frame is fixedly connected with a bearing box, a closed gear ring is slidably connected to the lower wall of the inner cavity of the bearing box, an incomplete gear extending into the inner cavity of the closed gear ring is rotatably connected to the middle of the inner cavity of the bearing box, and symmetrical sliding frames are slidably connected to the upper end of the bearing box. According to the office chair capable of relieving leg fatigue, by lifting a pull rod, connecting rods drive ejector rods to be separated from the side walls of the inner cavities of the sliding frames, sliding blocks can be freely adjusted in position, the incomplete gear is matched to drive the closed gear ring to reciprocate, and a front rack and a rear rack are made to reciprocate in a crossed mode through a guide rod, and therefore, the use requirements of different users are met, and the two legs can be well relaxed.

Description

Technical field [0001] The present invention relates to the field of office seats, in particular a office seat that can alleviate leg fatigue based on reciprocating motion. Background technique [0002] At present, according to most of the high-load work of most of the work users, the office seat of the office is also enhanced, which is no longer single to provide the user to provide writing support or placement of book information. It is an additional function that provides relaxation for fatigue workers.

Problems solved by technology

[0002] At present, according to the characteristics of high-load work of most office users, the office chairs supporting the office have also received a series of functional improvements. It no longer has the single function of providing users with writing support or placing books and materials, but It is an additional function to provide relaxation for tired workers. Since most office users need to sit for a long time, the leg joints cannot be effectively moved, so an office chair that can relieve leg fatigue can meet People's relaxation needs, but the general office chairs with leg relaxation function are poor in adjustability, cannot meet the needs of users of different sizes, and the relaxation effect on users' legs is average

[0003] Aiming at the deficiencies of the prior art, the present invention provides an office seat that can relieve leg fatigue based on reciprocating motion, which has the advantages of meeting the needs of different users and making the legs better relaxed, and solves the problem of general relief. Office chairs with tired legs cannot meet the needs of different users, and the relaxation effect on the legs is generally problematic
