Abstract
The utility model discloses an armrest structure of a chair. The armrest structure comprises a fixed arm and a movable arm, wherein the fixed arm is fixedly arranged on the chair; two ends of the movable arm are connected with the fixed arm; one end of the movable arm is hinged on the fixed arm, and the other end of the movable arm is connected with the fixed arm through a regulating mechanism; the regulating mechanism comprises tooth spaces located on the movable arm, a mounting part located on the fixed arm and a rotary knob located at the side of the mounting part and used for controlling the positions of the tooth spaces; and the mounting part comprises a sliding chute for inserting the movable arm and a mounting hole for mounting the rotary knob. An armrest of the chair is composed of the fixed arm and the movable arm, and the front end of the movable arm can rotate around a hinged axis, therefore, the height of the front end of the movable arm can be regulated through the regulating mechanism. The lifting function of the armrest is realized through the matched rotation of an Archimedes spiral rack with an equidistant spiral characteristic and the equidistant tooth spaces on the movable arm; and the armrest structure is simple and reasonable and low in production cost.
Description
Technical field
The utility model relates to a kind of chair accessory, is specifically related to a kind of armrests structure.
Background technology
Office chair generally comprises chair pin, lifting/inclining mechanism, seat cushion, backrest and is positioned at the handrail of seat cushion both sides, and handrail is one of parts important in the chair.In the prior art, the lifting handrail is fixed on the seat cushion both sides, and the handle lifting mechanism technology is that inside and outside tube seat cooperates, and straight line is toward rising.Lifting handrail fixed form is confined to be fixed on the seat cushion both sides separately mostly, does not have the fixedly function of backrest and seat cushion.Backrest was connected with another mechanism or stator with fixing needs of seat cushion.
Summary of the invention
Problem to be solved in the utility model is, at the deficiency of above-mentioned technology, designs a kind of handrail that both can utilize and is connected and fixed backrest and cushion, can reach again that handrail height can be regulated, armrests structure rational in infrastructure, cost-effective.
The utility model is that the technical scheme that its problem of solution adopts is:
A kind of armrests structure, comprise the lever arm that the fixed arm that is fixedly mounted on the chair and two ends are connected with fixed arm, one end of described lever arm is hinged on the fixed arm, the other end of lever arm is connected with fixed arm by governor motion, described governor motion comprises the teeth groove that is positioned on the lever arm, is positioned at the installation portion on the fixed arm and is positioned at the knob that the installation portion side is used for the control tooth slot position, the installing hole that described installation portion comprises the chute that inserts for lever arm, installs for knob.
In the utility model, described knob is provided with for the tooth bar that inserts the teeth groove profile of tooth, and this tooth bar is the spiral of Archimedes tooth bar with equidistant spiral characteristic.
In the utility model, the profile of tooth of described teeth groove is corresponding with the spiral of Archimedes tooth bar, and teeth groove and lever arm are one-body molded.
The beneficial effects of the utility model are: handrail of the present utility model is made up of fixed arm and lever arm, the front end of lever arm can rotate around hinge axes, therefore the height of its front end can be regulated by regulating governor motion, can adapt to the people of different heights or be suitable for the requirement of different gestures, make the people sit more comfortablely.Further, the spiral of Archimedes tooth bar of the utility model by having equidistant spiral characteristic cooperates rotation to realize the elevating function of handrail with equidistant teeth groove on the lever arm, and simple and reasonable for structure, production cost is low.
