Description
Technical field
This utility model relates to chair art, specifically a kind of convenient adjustment chair.
Background technology
Having number of types of seat on the market at present, be all fixed structure, cause that the mode only with sitting uses, the relatively single use of function is also convenient not.And adjustable seat is applied widely easy to use due to it, more it is subject to liking of more and more people, the device that regulates of traditional adjustable seat generally all utilizes the cooperation of draw-in groove and pin, it is stiff to connect, troublesome poeration, regulator site is generally all disposed near handle, once foreign object enters draw-in groove and is easy for stuck situation, there is potential safety hazard, it is necessary to the adjustable seat of a simple in construction safety.
Utility model content
This utility model to solve above-mentioned prior art Problems existing, it is provided that a kind of convenient adjustment chair, solves current adjustable seat and uses not convenient unsafe problem.
This utility model solves the technical scheme that its technical problem adopts: this convenient adjustment chair, including underframe, underframe front end extends to form the first support end obliquely, first support end leading portion is rotatably connected to seating pad, and underframe rear end thereof is connected to expansion link, and expansion link top is rotatably connected to link, link front end is rotatably connected on seating pad tail end, the second support end is extended in the rear end of link, the second support end is fixed with backboard, is fixed on link bottom backboard.After so arranging, backboard relies on link and seating pad to be rotationally connected, backboard just can around seating pad rotate, and with expansion link, underframe and link are connected, utilize the motion of expansion link to control the rotation of backboard, and then freely controlling the angle of the inclination of backboard, the people of seat can freely regulate oneself angle applicable.Position owing to regulating is put into the bottom of seat, the phenomenon that extraneous foreign body is stuck will not occur, shelves need not be relied on to regulate as traditional adjustment seat, simpler also safety and reliability.
Improving further, underframe bottom is rotatably connected to base, and base is fixed with some spikes in a circumferential direction.The firm of base is the basis that whole seat is firm, and some spikes on base in turn ensure that the firm of base on cost-effective basis, it is also possible to alleviates weight and is easy to carrying.
Improve further, support foot bottom and be all rotatably connected to roller.Roller adds the motility of seat, it is possible to moving freely seat, conveniently moving is laborsaving.
Improving further, seating pad both sides are respectively and fixedly provided with handle, and handle and backboard are hinged by connecting rod.When people is sitting on chair, handle provides a position that can place, and result of use is better；Handle is connected the stability strengthening backboard further with backboard, makes backboard be in a firm state, relieved seating.
Improve further, when backboard is tiltedly put, between the second support end and a spike, be connected to support bar.Support bar when backboard is tiltedly put, can strengthen the supporting role to backboard, it is ensured that the reliability of seat when people lies low on backboard.
This utility model has the advantages that: of the present utility model rational in infrastructure, compact, is rotationally connected between seating pad and backboard, reaches freely to regulate the purpose of chair angle by controlling expansion link, and structure is simplified, easy to operate, safe and reliable, is suitable to promote.
