Detailed Description
The invention is further described in detail below with reference to the drawings and examples.
An embodiment, referring to fig. 5, a headrest of a chair includes a headrest 1, a headrest bracket 2, a bracket positioning plate 3, and a fixing base 4.
Referring to fig. 9, the headrest 1 is rotatably connected with the headrest support 2, the headrest support 2 extends out of the two support arms 5, two opposite sides of the two support arms 5 are respectively provided with a pivot 6, two ends of the headrest 1 are respectively sleeved on the pivot 6, mutually meshed teeth 7 are respectively arranged between the pivot 6 and the ends of the headrest 1, the headrest is rotated forcefully, the pivot and the teeth at the ends of the headrest slide mutually, the adjustment direction of the headrest is realized, and after the headrest is stopped, the pivot and the teeth at the ends of the headrest are mutually meshed to realize positioning.
Referring to fig. 1 to 7, the handle 8 of the headrest support 2 is provided with a dovetail sliding block 9, the handle 8 of the headrest support is in sliding fit with the dovetail sliding block 9, the dovetail sliding block 9 is in rotary connection with the support locating plate 3 through a hinge 10, the hinge 10 is a hinge with damping, the hinge cannot rotate under the action of certain external force through self damping after being forcefully rotated, one face of the hinge 10 is fixedly connected with the support locating plate 3, and the other face of the hinge 10 is fixedly connected with the dovetail sliding block 9.
Referring to fig. 2 to 4, a strip-shaped groove 11 is formed in the headrest support handle 8, and racks 12 are arranged on two side walls of the strip-shaped groove 11. The surface of the dovetail sliding block 9 is fixedly provided with two locking strips 14 through a locating pin 13, the heads 19 of the two locking strips 14 swing relative to the locating pin 13, a reset spring 15 is arranged between the opposite surfaces of the two locking strips 14, and when the two locking strips are relatively closed, the two locking strips 14 can compress the reset spring to be meshed with each other. When the dovetail sliding block is combined with the handle of the headrest bracket, the two locking strips 14 are arranged in the strip-shaped grooves 11, and when the handle 8 of the headrest bracket slides relative to the dovetail sliding block 9, the two locking strips slide in the strip-shaped grooves. When the two locking strips 14 are positioned at the tail 16 of the strip-shaped groove, the widths of the two locking strips are equivalent to those of the strip-shaped groove, the two side walls of the strip-shaped groove press the two locking strips to be meshed with each other, then when the two locking strips are positioned at the head 17 of the strip-shaped groove, the head side walls of the strip-shaped groove are provided with extrusion opening blocks 18, the extrusion opening blocks 18 are used for expanding the two locking strips 14, the two locking strips are expanded by reset springs, when the headrest support is slid again, the two locking strips slide along the surfaces of the two racks 12 respectively, and when the headrest support stops sliding, the heads 19 of the two locking strips 14 can be propped against any position of the two racks to realize the positioning of the headrest support and the dovetail slide block.
