As long as all being protected by Patent Law in the right of the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of sofa headrest hinge, including connecting rod 1 and set on 1 one end of connecting rod
Headrest interconnecting piece 2.1 L-shaped setting of connecting rod comprising have the first rod segment 3 and the second rod segment 4, the first rod segment 3 and the second rod segment
4 one end connects and is mutually perpendicular to.One end of first rod segment 3 is threaded 5, and there are one blocks 6 and one for suit at the screw thread 5
A nut 7 to match with the screw thread 5, can be connected by the setting of screw thread 5 with the backrest of sofa.One end of second rod segment 4
It is fixedly connected with clamping block 8.
As shown in Figure 2, Figure 3 and Figure 4, headrest interconnecting piece 2 includes movable support 9, and the side of movable support 9 is fixedly connected with
Mounting plate 10, mounting plate 10 are vertical setting with movable support 9.It is provided with mounting hole 11 on mounting plate 10, passes through mounting hole 11
It can be connected and fixed with headrest.By rivet interlacement, there are two connecting plates 12 arranged in parallel for the side of movable support 9, each
One end of connecting plate 12 is fixedly connected with the flap 13 being bent to form, and the distance between two connecting plate 12 is more than two
The distance between flap 13 forms accommodating space between two flaps 13.The side of each flap 13 is provided with hinged
Mounting hole 14 and two arc tooth sockets 15, wherein hingedly mounting hole 14 is located between two arc tooth sockets 15, each arc tooth socket
15 outer arc side is provided with 7 lock teeth 16, and each lock tooth 16 is 15 degree around the angle of hinged mounting hole 14, to form 7 grades of rotations
Section, each grade of rotation size is 15 degree.
As shown in Fig. 2, Fig. 3 and Fig. 5, there are two the hinge brackets 17 mutually abutted for setting in above-mentioned accommodating space, often
One end of a hinge bracket 17 is fixedly connected with the fixed plate 18 of bending forming, and gap is provided between two fixed plates 18,
The clamping block 8 being fixedly connected with the second rod segment 4 is placed in gap.Clamping block 8 and the fixed plate 18 of both sides pass through rivet interlacement.Two
The side of a hinge bracket 17 is both provided with identical rack mounting apertures 19 and two arc locked grooves 20, wherein rack mounting apertures 19
Between two arc locked grooves 20.It is mounted on the same clamp spring 21 and the same locking plate 22 in two arc locked grooves 20,
One end of clamp spring 21 is adjacent to locking plate 22, to which locking plate 22 to be clamped in arc locked groove 20.The both ends of locking plate 22 extend to arc
Coordinated in tooth socket 15 and with lock tooth 16.
Above-mentioned rack mounting apertures 19 are corresponding with hinged mounting hole 14, and at rack mounting apertures 19 and hinged mounting hole 14
The same rivet carry out activity riveting can be passed through.
When connecting rod 1 is rotated with headrest interconnecting piece 2 towards the direction being located remotely from each other, so that connecting rod 1 and head
Angle between pillow interconnecting piece 2 becomes larger.At this point, the lock tooth 16 on articulated slab can drive the locking plate 22 that abuts against towards clamp spring
21 direction is moved, and clamp spring 21 is squeezed and is shunk, so that lock tooth 16 can be rotated；It is rotated further to logical
When crossing a lock tooth 16, locking plate 22 can restore to carry out card and state to lock tooth 16 again under the effect of the elastic potential energy of clamp spring 21.
The above-mentioned motion state for single lock tooth 16 and locking plate 22 if need to adjust to required angle can continue that articulated slab is driven to be turned
It is dynamic.Above-mentioned motion process cannot be moved towards opposite direction, and fixture block is in card and state with lock tooth 16.
As shown in Fig. 3, Fig. 4 and Fig. 5, hinge bracket 17 is provided with clamping portion 23 at arc locked groove 20, when fixture block outside
The mated condition with clamping portion 23 can be transformed under the action of power from original state.Flap 13 is provided at arc tooth socket 15
Lug boss 24.It is carried out with the last one lock tooth 16 when flap 13 and hinge bracket 17 relatively rotate to locking plate 22 with certain orientation
When cooperation, continue that articulated slab is driven to be rotated towards shrapnel direction in this case, the lug boss 24 being located on flap 13
It can press to locking plate 22, so that the direction of locking plate 22 towards clamp spring 21 is moved, since lug boss 24 can be with hinge
Carrier bar 13 is rotated, and then the side of locking plate 22 can be driven to turn to and matched with the clamping portion 23 on hinge bracket 17.
Under this state, due to locking plate 22 have certain gradient so that locking plate 22 not with lock tooth 16 be in contact, at this time flap 13 with
Hinge bracket 17 can relatively rotate and turn to minimum angles, when flap 13 and hinge bracket 17 turn to minimum angles
When, the locking plate 22 and the inner wall of arc tooth socket 15 that extend in arc tooth socket 15 abut against, and by 15 inner wall of arc tooth socket
Opposition so that locking plate 22 can from clamping portion 23 remove and restore to original state.
Above-mentioned motion process realizes the function of the rebound of headrest hinge.The angle of rotation of connecting rod 1 and headrest interconnecting piece 2
Degree can be divided into 7 grades, and 15 degree every grade, slewing area highest can effectively be met the actual needs to 105 degree.
The both sides of flap 13 in the present embodiment are provided with hinged cover 25, and the medium position of hinged cover 25 is provided with hinge
Lid mounting hole 26 can sequentially pass through hinged cover mounting hole 26, hinged mounting hole 14 and rack mounting apertures 19 by rivet, to
