Abstract
The utility model discloses an elastic reset device for a rotary chair chassis. The elastic reset device is a spring, one end of the spring is connected with a pin roll at the upper end of a backrest bracket, and the other end of the spring is connected with a pin roll at the lower end of a support frame. The rotary chair chassis mainly comprises a seat board, a support board, the backrest bracket and the support frame, wherein the seat board is connected with a seat, the backrest bracket is connected with a backrest, bottoms of the support frame and the backrest bracket are hinged with the support board, the seat board is hinged with the tops of the support frame and the backrest bracket, one end of the spring used as the elastic reset device is connected with the pin roll at the upper end of the backrest bracket, and the other end of the spring is connected with the pin roll at the lower end of the support frame, therefore, the backrest bracket is pulled to be kept in a state of inclining towards the front of the chair; and when people lean back, the seat moves backwards with the rotation of the backrest to ensure that the waist of the backrest is always clung to the corresponding position of the back of a human body, thus the friction of clothes with the back is avoided.
Description
Technical field
The utility model relates to a kind of Revolving chair chassis, particularly a kind of elasticity reset device for Revolving chair chassis.
Background technology
Revolving chair chassis also claims Revolving chair tray, is a vitals that is contained in swivel chair seat cushion below, the lifting of seat cushion, and the elevation angle of backrest is regulated and is all relied on the chassis to finish.
Present Revolving chair tray generally is comprised of parts such as top tray, lower joist, rotating shaft and spring assemblies, and after top rotary table and swivel chair seat back were fixing, swivel chair can be done suitable reclining around the shaft, and can initiatively reply, and makes the user that comfort be arranged.For example, Chinese patent discloses a kind of pallet, and (patent No. is: 02287885.8), mainly comprise base plate, sliding seat, conical pipe and adjusting device, sliding seat is movably connected in base plate, in the middle of sliding seat, connect the conical pipe of air pressure rod, be welded on together on the sliding seat by Taper Pipe fixed head and conical pipe; Described adjusting device includes adjusting rod, adjustable plate, torsion spring, torsion spring fixed head, and adjusting rod interts in sliding seat, and adjustable plate is fixedly connected on adjusting rod and inserts on the interior end of sliding seat, the one side contact air pressure rod of adjustable plate, and another side is connected with torsion spring; Be provided with adjustable plate at the another side of adjustable plate and end blade.
The adjusting device of above-mentioned Revolving chair tray is regulated by torque spring fully, and for the different people of body weight, the power of needed torque spring needs different, makes product not have good versatility.Be sitting on the seat that this Revolving chair tray is housed as the user, when directly sitting on backward reclining, the position of seat lumbar support human body can be offset, and affects comfortableness.
A kind of Revolving chair chassis of ad hoc meter, comprise the base plate that links to each other with the gas bar, the left and right sides at base plate vertically respectively is provided with a gripper shoe, gripper shoe and base plate are fixedly linked, along continuous straight runs is provided with to install the seat board of seat support above two gripper shoes, the both sides, front and back of base plate are respectively equipped with bracing frame and the backrest bracket that keeps tilting to swivel chair the place ahead, and the bottom of bracing frame, backrest bracket and two gripper shoes are hinged;
Specifically, backrest bracket respectively is provided with up and down a bearing pin, and bearing pin is plugged on the side plate of the backrest bracket left and right sides, and backrest bracket is hinged by bearing pin and the gripper shoe of lower end; Described bracing frame comprises two bearing pins that be arranged in parallel up and down, two bearing pins by about two connecting rods be arrangeding in parallel be fixedly linked; The both sides, front and back of seat board are hinged with the bearing pin on the top of bracing frame, backrest bracket respectively, can play a role in order to make the chassis, and backrest bracket, backrest can be resetted when the people does not lean on backrest, must increase a resetting means.
The utility model content
Can the utility model have overcome existing deficiency in the above-mentioned prior art, provide a kind of chassis that makes play a role, and the elasticity reset device that can reset to backrest bracket, backrest when the people does not lean on backrest.
The technical solution of the utility model is achieved in that
Be used for the elasticity reset device of Revolving chair chassis, described elasticity reset device is spring, and an end of spring links to each other with the bearing pin of backrest bracket upper end, and the other end of spring links to each other with the bearing pin of bracing frame lower end.
As preferably, described elasticity reset device is 2～4 springs.The quantity of spring can be set according to actual requirement.
Adopted principle of the present utility model and the beneficial effect of technique scheme to be:
Revolving chair chassis of the present utility model mainly comprises seat board, gripper shoe, backrest bracket and bracing frame, seat board links to each other with seat support, backrest bracket links to each other with backrest, bracing frame, bottom and the gripper shoe of backrest bracket are hinged, seat board and bracing frame, the backrest bracket top is hinged, and link to each other with the bearing pin of backrest bracket upper end as the spring one end of elasticity reset device, the other end links to each other with the bearing pin of bracing frame lower end, thereby holding backrest bracket makes it keep the state that tilts to seat the place ahead, the people is in the process of leaning on backward, seat support is also followed the rotation of backrest and is moved backward, make fit all the time correspondence position of human body back of backrest lumbar support, avoided clothing and back to produce friction.
