In order to realize above-mentioned object, the utility model have employed following technological scheme:
A kind of link of chair, comprise link body, described body at least stretches out two conversion adapters along both direction, two conversion adapters are respectively: for the conversion adapter a with front chair leg socket connection and for the conversion adapter b with the socket connection of rear chair pin, two conversion adapters a, b and the machine shaping of link body one.By arranging such link, the so simple Placement of employing grafting completes the connection between chair pin, and structure is simple, dismounting is convenient, and has good soundness; Effectively can increase transport volume after splitting transport, reduce cost of transportation.
As preferably, two conversion adapters a, b are inserted link or intubate.Preferably two conversion adapters a, b adopt inserted link, to meet the requirement of connectivity robustness.
Conveniently be connected with backrest, as preferably, this link also comprises the conversion adapter c for being articulated and connected with backrest.Conversion adapter c stretches to another way.
As preferably, the angle α between described conversion adapter a and conversion adapter b is acute angle, and the angle β between conversion adapter b and conversion adapter c is acute angle.Angle α is set to acute angle, make link with the grafting of forward and backward chair pin after, having good stability of chair entirety, not easily tumbles; Angle β is set to acute angle, and after hinged with backrest, backrest can not turn forward, and meets the use habit of people, uses more comfortable.
As preferably, described angle α is 60 ° of angles, and angle β size is between 60 ° ~ 90 °.Through overtesting, when angle α is 60 ° of angles, chair stability is best, and when angle β is between 60 ° ~ 90 °, backrest comfort level is higher.
As preferably, the end of described conversion adapter c is provided with for the cam a hinged with backrest, and described cam a protrudes from conversion adapter c end.
As preferably, the end parallel interval of described conversion adapter c is provided with two cam a.
As preferably, described link body is provided with the inserting groove for grafting handrail.
As preferably, the side opening of described inserting groove is provided with through hole.
As preferably, the side opening of conversion adapter a, b has for fastening attachment hole.When with the grafting of chair pin after, then to be fixed by screw locking or connecting pin grafting.
Compared with prior art, the beneficial effects of the utility model are: by arranging such link, forward and backward chair pin can freely be dismantled, link is formed in one and can meets fastness and requirement attractive in appearance, the connection between link and forward and backward chair pin is realized by inserting mode, by arranging cam a and the hinged connection completed between backrest and link of backrest, structure is simple, dismounting is convenient; Effectively can increase transport volume after splitting transport, reduce cost of transportation.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
The link of a kind of chair as shown in Fig. 1 ~ Fig. 6 and its use schematic diagram on chair, this both sides comprising backrest 1, chair pin and be arranged on chair are for connecting the link 4 of backrest 1 and chair pin.Described link 4 comprises link body, and stretch out three conversion adapters along three directions, respectively: connect the conversion adapter a5 of front chair leg 2, connect the conversion adapter b6 of rear chair pin 3 and connect the conversion adapter c7 of backrest 1, three conversion adapters and this body by integral forming of link.Adopt inserting mode to be connected between link 4 with forward and backward chair pin, connected by articulated manner between link 4 and backrest 1.Inserting mode between conversion adapter a5, conversion adapter b6 and forward and backward chair pin, both can be arrange spliced eye on forward and backward chair pin, conversion adapter a5, conversion adapter b6 be plugged on forward and backward chair pin, and now, conversion adapter a5 and conversion adapter b6 uses as inserted link; Also can be arrange spliced eye on conversion adapter a5, conversion adapter b6, forward and backward chair pin be plugged on conversion adapter a5 and conversion adapter b6, and now, conversion adapter a5 and conversion adapter b6 uses as intubate.Adopt the former in the present embodiment.Adopt the former in the present embodiment.
By arranging link 4, adopt grafting, the simple Placement such as hinged completes connection between backrest 1, chair pin, structure is simple, dismounting is convenient, and has good soundness; Effectively can increase transport volume after splitting transport, reduce cost of transportation.
The end of described conversion adapter c7 is provided with cam a8, and described cam protrudes from conversion adapter c end.Lower end, backrest 1 both sides is provided with joint 14, and described joint 14 front end is provided with the cam b9 protruding from joint 14; Described cam a8 and cam b9 is hinged, and the front end of joint 14 and the end of conversion adapter c offset and close.By arranging cam a8 and cam b9 and making both hinged connections completed between backrest 1 and link 4, dismounting is convenient, by the front end of joint 14 and the end of conversion adapter c offset incompatible make to install after, effectively fixing between the backrest 1 of chair and link 4, there is not relative displacement.
Angle α size between described conversion adapter a and conversion adapter b is 60 °, and the angle β size between conversion adapter b and conversion adapter c is between 60 ° ~ 90 °.After chair installation, angle α will be divided equally by vertical guide.Through test of many times, when angle α is 60 ° of angles, chair stability is best, and when angle β is between 60 ° ~ 90 °, backrest comfort level is higher.
As a kind of optimal way, the end of described conversion adapter c7 is arranged with two cam a8 in parallel, and the gap between two cam a8 is equal with the thickness of cam b9, and cam b9 is hingedly mounted in the gap between two cam a8.
As another kind of optimal way, the front end of described joint 14 is arranged with two cam b9 in parallel, and the gap between two cam b9 is equal with the thickness of cam a8, and cam a8 is hingedly mounted in the gap between two cam b9.
Due to the connection relative complex between the cam a8 of conversion adapter c7 and the cam b9 of backrest 1 front end, in order to reduce the assembling difficulty of user, before chair dispatches from the factory, fix between cam a8 and cam b9.Concrete means of fixation is, both is fixed, and on bearing pin, arrange jump ring in case shotpin axle is deviate from by arranging a bearing pin through the through hole of cam a8 and cam b9.
Preferably, chair can also arrange the handrail 10 with link 4 socket connection.Concrete Placement is: on link 4, the pendant position place of three conversion adapters is provided with inserting groove 11, and the bottom of handrail 10 is plugged in inserting groove 11.Be provided with through hole 12 at the side opening of inserting groove 11, the corresponding position, bottom of handrail 10 offers attachment hole 13, arranges one and is fixed on present link 4 by handrail 10 through the bearing pin 15 of through hole 12 with attachment hole 13.
