Description
Technical field
The utility model relates to a kind of component of chair, particularly a kind of detachable chair link.
Background technique
Chair is as using very generally and frequently furniture in daily life, its form structure is of a great variety, in order to provide stable and comfortable back-supported for user when in use, bench and backrest combination adopt bolt fixed structure more, no matter this structural design is to install or dismounting, all need use instrument to tightening or loosering a bolt, very inconvenient, especially for chair production plant, need to carry out the operation of a large amount of installation and removal backrests, this has extended assembling and take-down time undoubtedly, has also improved workman's labor intensity.
Model utility content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, for connecting the connection of bench and backrest, and the detachable chair link that facilitates backrest to install and dismantle.
The technical scheme in the invention for solving the above technical problem is: detachable chair link, it is characterized in that: formed by tenon parts and mortise parts, wherein the both sides in tenon parts front are protruding with dovetail gib block, the below of tenon parts is extended one and is had flexible external part, described external part is protruding with back-off, on tenon parts, offer backrest attachment hole, the back side of tenon parts is backrest junction surface, on described mortise parts, offer seat attachment hole, the back side of mortise parts offers dovetail groove, described dovetail groove and dovetail gib block match, the lower end of tenon parts is provided with back-off baffle plate and tenon baffle plate, the front of mortise parts is seat junction surface.
As preferably, on seat junction surface described in the utility model, be also fixed with two positioning pins.
As preferably, seat junction surface described in the utility model is inner concave.
As preferably, backrest junction surface described in the utility model is made up of the arc cylinder of evagination and the plane that is arranged on arc cylinder both sides.
As preferably, tenon parts described in the utility model and mortise parts all adopt integrated injection forming.
As preferably, on arc cylinder described in the utility model, be provided with polygonal projection, one end of described backrest attachment hole is arranged on projection.
The beneficial effects of the utility model are:
1) in assembling, tenon parts are fixed on backrest, mortise parts are fixed on leaning against on frame of bench, the dovetail gib block of tenon parts is inserted to mortise parts dovetail groove, can realize the connection of backrest and bench, and tenon baffle plate can block tenon parts continuous slide, now the back-off of external part snaps in the below of back-off baffle plate, back-off can prevent moving up of the relative mortise parts of tenon parts with back-off baffle plate, thereby guarantee that tenon parts are fastened on certain position, be firmly difficult for loosening; In dismounting, can utilize hand or instrument that external part is broken into two with one's hands, make back-off depart from back-off baffle plate, backrest is upwards proposed, can realize the disengaging of backrest and bench, convenient and swift.
2) mortise parts connect bench lean against frame time, inserts the positioning hole leaning against on frame by positioning pin, only need a screw, can realize mortise parts and lean against being fastenedly connected of frame, backrest is difficult for becoming flexible.
3) be welded because back rest adopts metal pipe element more, therefore profile mostly is outer male structure, connects back rest by the seat junction surface of inner concave structure, can realize and being connected better, has improved the soundness of combination.
4) in arm chair, the design of some, to adopt block rubber to be connected with back rest, backrest junction surface is designed to the cylndrical surface of indent and the structure of plane combination, thereby the structure of this backrest junction surface for providing better mechanics, is supported block rubber, make rubber be not easy to walk, improved soundness and the working life of structure.
5) tenon parts and mortise parts adopt injection moulding manufacture, and tenon parts and mortise parts all can form integral structure, and the material of plastics has also guaranteed that external part has certain elasticity.
