Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted that
For the explanation of these embodiments is used to help understand this utility model, but do not constitute to restriction of the present utility model.This
Outward, as long as technical characteristic involved in this utility model disclosed below each embodiment does not constitute conflict each other
Can just be mutually combined.
As shown in Fig. 1～Fig. 6, a kind of seat of rotatable backrest, including chair frame 1, seat support 2, backrest 3, backrest connector
44th, spring 5 and bolt 6, axisymmetricly, 1 middle setting of chair frame has a supporting part to 1 both sides of chair frame, supporting part by support shaft and
Rectangular fulcrum composition is connected into support shaft, support shaft is fixedly connected with seat support 2 by fixture 7 with fulcrum, wherein, Gu
Determine part 7 to be made up of upper fixing element 71 and lower fixture 72,71 surface of upper fixing element is provided with and can accommodate the two of support shaft and fulcrum
Individual groove 711, during installation, support shaft and fulcrum are just located at two grooves 711, and the surface of 71 un-grooved of upper fixing element respectively
It is fixedly connected with seat support 2, groove forms position-limiting action to support shaft and fulcrum, and the surface of lower fixture 72 is provided with and covering
The recess of recessed grain that support shaft is located, by the cooperation of recess and groove, can be fully wrapped around by support shaft portion in the grooves,
On the one hand the load-bearing of support shaft is reduced, on the other hand increases the fastness installed.1 both sides of chair frame are provided with armrest part 11, handrail
The rear side end in portion 11 is connected with backrest 3 by backrest connector 4, and backrest connector 4 is L-shaped, and 4 one end of backrest connector is
Hollow structure, in the inside of the hollow structure, the bottom parallel with end face is provided with 5 hole of fixing hole and spring, and in hollow structure
The circumference side in portion is provided with rotary stopper projection 41, spring retainer projection 42 and the auxiliary projection 43 of arc, rotary stopper
Projection 41, spring retainer projection 42 and auxiliary projection 43 project the end face of backrest connector 4, wherein, rotary stopper projection
41 length for projecting 4 end face of backrest connector are more than spring retainer projection 42 and auxiliary projection 43 projects 4 end of backrest connector
The length in face, the surface of the rear portion both sides of backrest 3 are provided with installation position, and the one end contacted with backrest connector 4 on installation position is set
Hollow linking position 32 is equipped with, the other end is provided with stepped bolt position 31, and linking position 32 is internally provided with prominent with rotary stopper
