It connects, the rotation axis 3 is rotationally connected with fixed plate 1；Specifically, one end of the regulating arm 4 and fixed plate 1 are cut with scissors referring to Fig. 3
It connects, forms a supporting surface 41 along bending under the other end of the regulating arm 4, supporting surface 41 is equipped with several fixation holes 411, adjusts
Joint arm 4 is fixedly connected using screw with headrest by fixation hole 411；The rotation axis 3 can be connected with regulating arm 4 using screw
It connects, weld or is integrally formed as preferably, the utility model is connected using welding manner.The rotation axis 3 connects with teeth
Wheel block 5, the fixed link 2 or/and fixed plate 1 are installed with elastic component 7 and for abutting rack gear block 6 to cluster gear 5, the bullet
Property part 7 be spring, one end of the elastic component 7 abuts with fixed link 2, and the other end of elastic component 7 is abutted with rack gear block 6.Specifically
, rack gear block 6 is equipped with several teeth 62, and cluster gear 5 is equipped with latch 52, and rack gear block 6 is under the elastic force effect of elastic component 7
It engages multiple teeth 62 of rack gear block 6 with the latch 52 on cluster gear 5, clamping is carried out to cluster gear 5, to lock regulating arm
4 position, multiple teeth 62 can effectively improve rack gear block 6 to the clamping force of cluster gear 5, to effectively mention with engaging for latch 52
The high bearing capacity of headrest.Each latch 52 of cluster gear 5 be 3 °, cluster gear 5 can be set as needed multiple latches 52 with
Different card shelves are formed, each card shelves adjust 3 °, and settable 36 grades general, adjustable-angle is 108 °, is also adjustable to certainly
200 ° for different demands.
As shown in Figure 1, when in use, user, which can only pull headrest, makes regulating arm 4 drive rotation axis 3 clockwise around axle center
Rotation is to carry out the angular adjustment to headrest, and during rotation, the drive cluster gear 5 of rotation axis 3 overcomes the elastic force of elastic component 7,
The latch 52 of cluster gear 5 is set to be detached from the rotation for engaging realization regulating arm 4 with rack gear block 6；One latch of every rotation of cluster gear 5
52, the angle of headrest generates variation, and when the angle of headrest is suitable, regulating arm 4 is pulled in stopping, and rack gear block 6 is just in elasticity
Lower reset of the elastic force effect of part 7 carries out clamping to cluster gear 5, locks the position of regulating arm 4 at this time.
As depicted in figs. 1 and 2, the cluster gear 5 is installed with clutch part 8, clutch part 8 for squeezing tooth pushing stick 6 so that
Rack gear block 6 is separated with cluster gear 5, and user need to only use clutch part 8 to squeeze tooth pushing stick when being resetted counterclockwise to headrest
6, so that rack gear block 6 is separated with cluster gear 5 to cancel meshing state, so that rack gear block 6 is made to discharge the locking to cluster gear 5, this
When regulating arm 4 can be rotated counterclockwise around the axle center of rotation axis 3.Preferably, the clutch part 8 is installed in cluster gear 5
Side, the side of the clutch part 8 are equipped with the convex extension part 81 for pushing rack gear block 6 open, and the rack gear block 6 is equipped with and convex extension part 81
The boss 61 of abutting；The other side of the clutch part 8 is equipped with abutting part 82, and the outside of the cluster gear 5 is equipped with to be supported for accommodating
The groove 51 of socket part 82.Specifically, as shown in figure 4, groove 51 is equipped with the first slot for being respectively used to be abutted with abutting part 82
Wall 511 and the second cell wall 512.When headrest turns to the last one gear, only need to continue to stir headrest makes regulating arm 4 around rotation
Axis 3 rotates clockwise, and rotation axis 3 drives cluster gear 5 to rotate at this time, until the first cell wall 511 and the clutch part 8 of cluster gear 5
Abutting part 82 abuts and clutch part 8 is pushed to rotate, and the rotation of clutch part 8 abuts convex extension part 81 simultaneously with the boss 61 of rack gear block 6
Rack gear block 6 is pushed away into cluster gear 5, so that rack gear block 6 be made to separate cancellation engagement with cluster gear 5；Then user can will rest the head on
Toward stirring counterclockwise, when headrest back turns to first grade, the second cell wall 512 of cluster gear 5 is abutted and is pushed away with abutting part 82
Dynamic clutch part 8 rotates, and the rotation of clutch part 8 makes convex extension part 81 leave boss 61, to make rack gear block 6 in the elasticity of elastic component 7
Lower reset of effect carries out clamping to cluster gear 5.
In the present embodiment, as shown in Figure 5 and Figure 6, the convex extension part 81, which is equipped with, protrudes out block 811, and the boss 61, which is equipped with, to be used
The cavity 611 of block 811 is protruded out in receiving.In practical applications, when headrest clockwise adjust angle when, the convex extension part 81 it is convex
It stretches block 811 to be embedded in cavity 611 always, engages the teeth 62 of rack gear block 6 with the latch 52 of cluster gear 5；When headrest is clockwise
When adjusting a last card shelves, continuation stirs regulating arm 4 clockwise, makes regulating arm 4 that cluster gear 5 be driven to rotate, cluster gear 5
Rotation promotes the abutting part 82 of the first cell wall 511 and clutch part 8 and clutch part 8 is pushed to rotate, thus make to protrude out block 811 remove it is recessed
Chamber 611, and squeeze and push away boss 61 and separate rack gear block 6 with cluster gear 5, headrest can be rotated counterclockwise reset by user at this time；
Headrest reseting procedure in, the block 811 that protrudes out of the convex extension part 81 is abutted with boss 61 always, make rack gear block 6 teeth 62 and
The latch 52 of cluster gear 5 separates, when headrest returns to initial gear, the second cell wall 512 of cluster gear 5 and supporting for clutch part 8
Socket part 82, which abuts, simultaneously pushes clutch part 8 to rotate, and makes to protrude out block 811 and is embedded in cavity 611, thus make the teeth 62 of rack gear block 6 with
The latch 52 of cluster gear 5 engages again.The structure designs simple and compact, stable and reliable operation.
In the present embodiment, as shown in figure 5, the accommodation groove that the fixed link 2 is equipped with sliding groove 21 and is connected to sliding groove 21
22, the sliding of rack gear block 6 is located in sliding groove 21, and elastic component 7 is located in accommodation groove 22.At work, rack gear block 6 is in elasticity
It is slided under the action of part 7 along sliding groove 21, the design of sliding groove 21 is with can enabling 6 stability of rack gear block mobile, effectively prevent
The disabler of the utility model caused by the mobile dislocation of rack gear block 6, to improve the stability of the utility model；In addition,
The design of the structure maximumlly utilizes the confined space, so that head can be realized by so that the utility model is able to use less part
The function of rotatably adjusting is rested the head on, effectively saving manufacturing cost.
