The specific embodiment
Please refer to shown in Fig. 1 to Fig. 2, it has demonstrated the concrete structure of the preferred embodiment of the utility model.This headrest 100, refers in particular to the headrest of a kind of office seat, includes headrest base 10, headrest backboard 20, headrest interlock plate 30 and headrest shell 40.Deflection mechanism 50 before and after arranging between this base and headrest backboard 20, arranges reciprocating mechanism 60 between headrest backboard 20 and headrest interlock plate 30, between this headrest interlock plate 30 and headrest shell 40, multidirectional deflection mechanism 70 is set.Coordinated left, right, front and rear, the upper and lower multi-direction beat of realizing headrest by front and back deflection mechanism 50, reciprocating mechanism 60 and multidirectional deflection mechanism 70, and can regulate the height of headrest, increase the comfort of headrest, meet the demand of different people.
Wherein, as shown in Fig. 3-6, described front and back deflection mechanism 50 comprises turning cylinder 51, the first spring 52, two buckling pieces 53 and a button spring 54, on corresponding headrest base 10 and headrest backboard 20, be equipped with articulated section 11,21, this turning cylinder 51 is arranged between two articulated sections 11,21, button spring 54 is installed on turning cylinder 51 and is connected to base and headrest backboard 20, this first spring 52 is installed in the endoporus 511 of turning cylinder 51, and two buckling piece 53 buckle-types are connected in turning cylinder 51 two ends and push against in the first spring 52.In the present embodiment, be provided with button hole 512 in the both sides of turning cylinder 51, two buckling pieces 53 of correspondence are provided with the buckle 531 of elastically deformable, this buckle 531 is interlocked with button hole 512, thereby realizes the fastener type assembled of the two, and this assembling mode is not only assembled easily, without screw, and convenient disassembly.
As shown in Figure 7,8, headrest base 10 is connected in the top of back, and people's head leans against on headrest shell 40, when people's the head back application of force, can compression button spring 54, backboard 20 headrest base 10 certain angle that rotates backward relatively that makes to rest the head on, thus realize headrest 100 beat backward.In the time that people's head leaves headrest shell 40 or the active force that applies and is less than the elastic force of button spring 54, these headrest 100 entirety beat forward.By this, realize the front and back beat function of headrest 100.
As shown in Fig. 9-11, described reciprocating mechanism 60 comprises headrest slide 61 and screw 62.The headrest backboard 20 of correspondence is provided with a vertical chute 22, and the lower end of this headrest interlock plate 30 is provided with slide block 31.This headrest slide 61 is fixed on headrest backboard 20 by screw 62 vertical chute 22 is enclosed and forms hoistway 63, this slide block 31 be inserted in hoistway 63 and relatively hoistway 63 move up and down.In the present embodiment, described slide block 31 outsides are provided with wavy multistage spacing preiection 311, headrest slide 61 inner sides of correspondence are provided with arc shaped contact 611, this arc shaped contact 611 is inconsistent with multistage spacing preiection 311, realizing thus multistage height regulates, after arc shaped contact 611 regulates, stop at a certain joint projection of multistage spacing preiection 311 upper, available arc shaped contact 611 is spacing motionless with the projection of this joint, thereby realizes the multistage regulatory function of height.In addition, slide block 31 outer side surfaces of the both sides of described multistage spacing preiection 311 are provided with stopper slot 32, headrest slide 61 interior sidewall surface of arc shaped contact 611 both sides of correspondence are provided with limited block 612, this limited block 612 embeds in stopper slot 32 slidably, this design can be carried out the path of sliding spacing, avoids slideway sideslip.
As shown in Figure 12-15, when firmly headrest interlock plate 30 upwards being pulled up, make slide block 31 in the interior slip of hoistway 63, arc shaped contact 611 is pressed in multistage spacing preiection 311 surfaces simultaneously, along with the every rising one-level of multistage spacing preiection 311 of headrest interlock plate 30, itself and arc shaped contact 611 are just carried out once spacing, until receive the limit, can can not continue to pull when terminating in limited block 612, avoid skidding off.With opposite way, by headrest interlock plate 30, to pressing down, 10 reductions to heavens can make to rest the head on.Realize by this overall height regulating function of headrest 100.
As shown in Figure 16-18, described multidirectional deflection mechanism 70 comprises headrest tumbler 71, horizontal latch 72, vertical latch 73, headrest buckle 74 and a screw 62, the headrest interlock plate 30 of correspondence is provided with a mounting groove 33, this headrest buckle 74 is installed in mounting groove 33 by screw 62, one side of this headrest tumbler 71 is connected in headrest buckle 74 by vertical latch 73, and another opposite side of this headrest tumbler 71 is articulated in the articulated section 41 at headrest shell 40 back sides by horizontal latch 72.In addition, between described headrest tumbler 71 and the inwall of mounting groove 33, butt has two second springs 76, and this two second spring 76 is distributed in the both sides of headrest buckle 74.
As shown in Figure 19-21, when people's hindbrain leans against headrest shell 40, during to the left side application of force of headrest shell 40, second spring 76 in compression left side, thereby whole headrest 100 beat left; In the time of the right application of force to headrest shell 40, whole headrest 100 beat to the right.As shown in Figure 22-23, in the time of the upper end application of force to headrest shell 40, the whole headrest 100 of side beat upward, in like manner also beat downwards.By this, can be left and right according to people's the application of force, upper, enter integrated moving headrest 100, increase the comfort level that people lean on.
In sum, design focal point of the present utility model is, it is mainly deflection mechanism 50 before and after arranging between this base and headrest backboard 20, between headrest backboard 20 and headrest interlock plate 30, reciprocating mechanism 60 is set, between this headrest interlock plate 30 and headrest shell 40, multidirectional deflection mechanism 70 is set; Realize the front and back beat of headrest, realize height of headrest adjusting, realize headrest 100 forward and backward, upper and lower multi-direction beats by multidirectional deflection mechanism 70 by reciprocating mechanism 60 by front and back deflection mechanism 50, by this, increase the comfort of headrest, meet the demand of different people.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
