Preferably, pin is in the time of pin activity bit bottommost and benchmark gear and dowel contact, and installing plate becomes 90 degree with clutch-plate.Its beneficial effect is, by benchmark gear and dowel contact, to realize location accurately.
Preferably, clamping plate are provided with the first contact-making surface, and clutch-plate is provided with the second contact-making surface, and the first contact-making surface is concordant with the second contact-making surface.Its beneficial effect is, by concordant contact-making surface, to play the effect of being convenient to installation.
Preferably, being centered close on straight line of the second through hole, third through-hole and the fourth hole on clamping plate.Its beneficial effect is, by by three concordant being located on same straight line of axle, to play the effect of convenient rotation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has schematically shown the headrest joint according to a kind of embodiment of the present utility model.As shown in Figure 1, headrest joint, comprise installing plate 1, clutch-plate 3, pin 4, the first axle 7, the second axle 6, the 3rd axle 5 and two clamping plates 2, as shown in Figure 2, installing plate 1 is provided with the first through hole 11, return gear 12, benchmark gear 14, contact position 13, as shown in Figure 3, clamping plate 2 are provided with the second through hole 21, third through-hole 22, fourth hole 23 and pin activity bit 24, as shown in Figure 4, clutch-plate 3 is provided with fifth hole 31, circular groove 32, clutch position 33 and step position 34, in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, two clamping plates 2 one end clamping installing plates 1, its other end clamping clutch-plate 3, the first axle 7 connects the first through hole 11 and the second through hole 21, the second axle 6 connects third through-hole 22 and circular groove 32, the 3rd axle 5 connects fourth hole 23 and fifth hole 31, pin 4 is placed in pin activity bit 24.Wherein pin 4 is in the time that pin activity bit 24 bottommosts and benchmark gear 14 contact with pin 4,3 one-tenth 90 degree of installing plate 1 and clutch-plate.Clamping plate 2 are provided with the first contact-making surface 25, and it is concordant with the second contact-making surface 35 and be horizontal plane that clutch-plate 3 is provided with the second contact-making surface 35, the first contact-making surfaces 25.Being centered close on straight line of the second through hole 21, third through-hole 22 and fourth hole 23 on clamping plate 2.
When headrest joint is rotated counterclockwise, as shown in Figure 5, when installing plate 1 is rotated counterclockwise maximum angle, the highest point of pin 4 in pin activity bit 24, contact position 13 contacts with clutch position 33, and clutch-plate 3 plays and supports and spacing effect; Return gear 12 contacts with pin 4 simultaneously, and step position 34 props up pin 4, when clutch-plate 3 plays stressed support, also makes pin 4 can not come off, thereby realizes the accurate location in headrest joint.In the time that installing plate 1 continues to be rotated counterclockwise, due to support and the positioning action of clutch-plate 3, the joint that makes to rest the head on cannot be rotated further, thereby realizes spacing function, and is not easy to become flexible.
When headrest joint turns clockwise, as shown in Figure 6, when installing plate 1 is rotated clockwise to maximum angle, pin 4 is at pin activity bit 24 bottommosts, and benchmark gear 14 contacts with pin 4, now 3 one-tenth 90 degree of installing plate 1 and clutch-plate, pin 4 plays the effect of supporting and locating.In the time that installing plate 1 continues to turn clockwise, due to support and the positioning action of pin 4, the joint that makes to rest the head on cannot be rotated further, thereby realizes spacing function, and is not easy to become flexible.
Concordant on same straight line with the 3rd axle 5 three axles due to the first axle 7, the second axle 6, make installing plate 1 stressed more even when rotated, thereby make rotation milder, there will not be the situation of effort.The first contact-making surface 25 and non-inclined-plane concordant with the second contact-making surface 35, only has any one contact-making surface of alignment just can install, and will align without each contact-making surface while making to install, make easier for installation.
Above-described is only an embodiment of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
