Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but As long as it is all protected in the right of the utility model by Patent Law.
Embodiment:A kind of sofa headrest hinge, as depicted in figs. 1 and 2, including determining by the way that articulated shaft 4 is hinged Hinge component 1 and hinge component 2 living, and hinge component 2 living will determine hinge component 1 and be clipped in the middle, the both sides of hinge component 2 living are fixed with hinged cover 3。
Determine hinge component 1 and include connecting portion 5 and jam plate portion 6, connecting portion 5 is used to be fixed on sofa backrest.Hinge component 2 living wraps Mounting portion 7 and hinge part 8 are included, mounting portion 7 is fixed on sofa headrest.Jam plate portion 6 and hinge part 8 are hinged, and hinge Portion 8 can be rotated around jam plate portion 6 around certain angle, and hinge part 8 is provided with groove close to 6 side of jam plate portion, is fixed in groove restricted The position-limit mechanism 9 that hinge part 8 turns round.When needing to adjust the angle between sofa headrest and sofa backrest, sofa headrest is rotated, Make to be fixed on the work hinge component 2 on sofa headrest and rotate respective angles around the hinge component 1 of determining being fixed on sofa backrest, later, Position-limit mechanism 9 is connected between jam plate portion 6 and hinge part 8, hinge part 8 is made to be not easy to turn round, and then sofa headrest is made to be leaned on sofa The back of the body can be stably maintained at preset angle.
It is in an arc transition 17 between articulated section and mounting portion 7.Arc transition 17 makes two pieces of articulated slabs 10 extend in peace The part in dress portion 7 can be compressed tightly against together, and then can clamp the jam plate 14 between two pieces of articulated slabs 10, make hinge Stability higher.
Articulated slab 10 is equipped with socket 18, and cover board is equipped with the plug 19 being connect with 18 interference of socket.19 interference of plug Connection is inserted into socket 18, and cover board and articulated slab 10 are fixed together, increase the stability of hinge.
Connecting portion 5 and mounting portion 7 have the two groups of mounting holes 20 for facilitating and being fixed on hinge between connection component.Peace Dress hole 20, which facilitates, is bolted on connecting portion 5 and mounting portion 7 on connection component, not only increases the fastness of device, And it is convenient for changing and repairs hinge.
Every group of mounting hole 20 includes the through-hole 21 that four sizes are identical and annularly arrange.Lead on the through-hole 21 being circular layout It crosses bolt to be fixed on connection component, makes to be not susceptible between connecting portion 5 and mounting portion 7 and connection component to slide relatively, into one Step increases the stability of hinge.
As shown in Figures 2 and 3, hinge part 8 includes the articulated slab 10 positioned at 14 both sides of jam plate, and position-limit mechanism 9 includes being set on Articulated slab 10 is provided on ratchet 11 on 14 side of jam plate and with the ratchet 11 that articulated slab 10 rotates on a quarter semi arch Arc tooth socket 12, position-limit mechanism 9, which further includes, is inserted into arc tooth socket 12 and limits the arc locking plate 13 that ratchet 11 rotates.In arc Locking plate 13 is inserted into arc tooth socket 12, since arc locking plate 13 is to the restriction effect of ratchet 11, makes ratchet 11 can only be to a side To rotation;When hinge part 8 is rotated around articulated shaft 4 to a rotary direction, the ratchet being located on articulated slab 10 is driven 11 rotations, after being adjusted to predetermined angle, arc locking plate 13 is inserted into another arc tooth socket 12 of ratchet 11, and limitation ratchet 11 returns Turn, and then achieve the purpose that hinge is enable to be stably held in predetermined angle.
Jam plate portion 6 includes the jam plate 14 that stacks of two panels, and position-limit mechanism 9, which further includes, to be fixed on jam plate 14 and towards hinge The support column 15 of fishplate bar 10 is socketed with the compression spring 16 in compressive state on support column 15, and 16 one end of compression spring is fixed on arc locking plate On 13,16 other end of compression spring is fixed on jam plate 14.Compression spring 16, there are one the effect compressed, makes arc locking plate to arc locking plate 13 The effect that 13 limitation ratchets 11 turn round is more preferable, further hinge is enable to be stably held in predetermined angle.
The course of work and principle:By the cooperation of the arc tooth socket 12 on ratchet 11 and arc locking plate 13, hinge is formed Multi gear position is adjusted, and the purpose of angle between sofa headrest and sofa backrest can be adjusted according to actual demand, increases the head of people Portion leans against the comfort on sofa.The process that this sofa headrest hinge adjusts headrest angle is easy, and uses arc locking plate 13 are inserted into the position limiting structure in arc tooth socket 12, and stability is high, headrest can be made to be maintained at preset angle of inclination for a long time.
