Description
Technical field
The utility model relates to a kind of Revolving chair chassis, particularly a kind of gas bar controlling organization 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 special research and development design, 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 to bracing frame and the backrest bracket of the inclination of swivel chair the place ahead, bracing frame, the bottom of backrest bracket and two gripper shoes are hinged, backrest bracket respectively is provided with up and down a bearing pin, bearing pin is plugged on the side plate of the backrest bracket left and right sides, the both sides, front and back of seat board respectively with bracing frame, the top of backrest bracket is hinged, and backrest bracket is connected with the elasticity reset device that it is tilted to swivel chair the place ahead.When the people is sitting in the process of leaning on backward on the chair, such as Fig. 2, shown in Figure 3, seat support, seat board are also followed the rotation of backrest bracket, backrest and are moved backward, backrest bracket can drive the seat board interlock, make fit all the time correspondence position of human body back of back rest supports, backrest keeps relative fixing with people's back, has avoided clothing and back to produce friction.
But someone wishes that backrest lock is fixed on one identifies oneself comfortable position, to take a nap after lunch or to have a rest for a long time, solves this problem so increased again the backrest locking mechanism.The backrest locking mechanism comprises positioning seat, the rear end of positioning seat is fixedly linked with the backrest bracket that is connected backrest, the front end of positioning seat offers many clamp bar slots from top to bottom, base plate on the chassis slides and is provided with the latch that matches with the draw-in groove of positioning seat, the latch upper end is provided with the latch location-plate that prevents the latch perk, and latch location-plate and base plate are fixedly linked; Realizing latch to locking, the release of positioning seat by the control latch, is the problem that needs solution but how to move the control latch.
Now designing a latch slide control device controls latch and moves, it comprises handle, torque spring, handle is L shaped, handle is to be connected to form by two sections of handle and drive links, the gripper shoe that handle passes the chassis is exposed to outside the chassis, drive link is connected to leader's rotating shaft locating piece near this end movable sleeve of handle, and handle rotating shaft locating piece is installed on the base plate on chassis by a screw, and handle rotating shaft locating piece rotates around screw; Torque spring is socketed on the torsion spring set screw, the torsion spring set screw is installed in screw fixed block upper end, screw fixed block lower end and base plate are fixedly linked, the first spring arm of torque spring is plugged in the hole of latch rear end, and the second spring arm of torque spring is plugged in the hole of drive link away from this end of handle; Handle is stirred in front and back, and handle integral body is rotated around screw, drives torque spring and rotates, and under the elastic force effect of torque spring, the release of the first spring arm pulling latch, retraction are to realize locking, the release of latch.
But generally, each swivel chair has a gas bar controlling, if control increases a control handle again for the gas bar, then can increase cost, and overall structure is also succinct not.
The utility model content
The utility model has overcome existing deficiency in the above-mentioned prior art, a kind of gas bar controlling organization that swivel chair gas bar is controlled is provided, this mechanism and latch slide control device share a handles, very ingenious, brought into play the maximum effect of handle, and reduced cost, made whole appearance seem more succinct.
The technical solution of the utility model is achieved in that
The gas bar controlling organization that is used for Revolving chair chassis, comprise handle, connecting plate and extension spring, handle is L shaped, handle is to be connected to form by two sections of handle and drive links, the gripper shoe that handle passes the chassis is exposed to outside the chassis, drive link is connected to leader's rotating shaft locating piece near this end movable sleeve of handle, handle rotating shaft locating piece is installed on the base plate on chassis by a screw, one end and the drive link of connecting plate are welded and fixed, the other end level of connecting plate is provided with a compressing tablet, compressing tablet contacts with the gas lever switch head of gas masthead section all the time, and an end of extension spring catches on connecting plate, and the other end of extension spring links to each other with base plate; Stir up and down handle, drive link is rotated, and then drive the lever switch head of calming the anger under connecting plate, the compressing tablet to reach the purpose of control gas bar.
