Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is front view of the present utility model;
Fig. 2 is lateral plan of the present utility model;
Fig. 3 is the structural representation of limit dais.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to Fig. 3, a kind of automotive seat latch that the utility model provides, it is arranged between the chair body of automotive seat and headrest, and it is the distance for regulating between headrest and chair body, and it mainly comprises coupling end 100 and limit dais 200.
Coupling end 100, it is the post shapes of inner hollow, and its symmetry assigns into the both sides on chair body top, and bottom it, offer two symmetrical strip-shaped clamp groove 110, draw-in groove 110 matches with chair body, and coupling end 100 is arranged on by draw-in groove 110 detouchable with it chair;
The side of coupling end 100 is also provided with detent mechanism, and detent mechanism specifically comprises the first positioning table 120 and the second positioning table 130, first positioning table 120 and the second positioning table 130 and lays respectively at both sides.
First positioning table 120, it is an oblong boss, and when it is for assigning into chair body coupling end 100, the distance of vertical movement positions, and when component contact in the first positioning table 120 and chair body, coupling end 100 just cannot continue to move down;
Second positioning table 130, it is a bayonet socket shape, and specifically can offer a square opening in coupling end 100 side, fastener 131 one end is fixed on the side of square opening, and fastener 131 can carry out left-hand revolution, and fastener 131 is provided with a boss 132;
Second positioning table 130, it is for preventing coupling end 100 from rotating in chair body, and when coupling end 100 is assigned into chair body, chair body can withstand fastener 131 and carry out left-hand revolution, and boss 132 can withstand chair body, and coupling end 100 can not be rotated in chair body.
Like this, by detent mechanism, coupling end 100 is made to be positioned in chair body, highly stable.
Limit dais 200, it is arranged on above coupling end 100, its overall square shape, and limit dais 200 inside is also hollow, through hole is provided with in limit dais about 200 both sides, and these two through holes respectively with the inner space of coupling end 100, like this, the connecting rod of headrest bottom can be connected with chair body with coupling end 100 through through hole successively.
Limit dais 200, it is for carrying out spacing to the connecting rod of headrest bottom, being provided with a stop gear therein;
Stop gear comprises limit button 210, limit spring 220 and spacing slideway 230;
Spacing slideway 230, it is two symmetrical tracks, and the end of these two tracks is connected with the through hole on the downside of limit dais 200 respectively.
Limit spring 220 is arranged on spacing slideway 230, limit spring 220 can be slided on spacing slideway 230, and, limit spring 220 contacts with the connecting rod of headrest bottom, limit spring 220 can withstand connecting rod, connecting rod can not be moved down, and only have when limit spring 220 is slided, connecting rod just can move down;
Limit button 210 is connected with limit spring 220 through the side of limit dais 200, moves by pinning limit button 210 thus promoting limit spring 220.
Like this, when needing to regulate the distance between headrest and chair body, only need pin limit button 210, just headrest can be elevated, after adjustment, not pin limit button 210.
The latch that the utility model provides is plastic body, and adopt mould one-shot forming, such low cost of manufacture, impregnability is high again.
General all heavier owing to resting the head on, prevent headrest from being damaged by pressure by latch, an annular table 140 is provided with in coupling end 100 side, annular table 140 is connected with the first positioning table 120, first positioning table 120 can support annular table 140, and in annular table 140, even distance is provided with several reinforced ribs 141, and these reinforced ribs 141 are connected with limit dais 200 respectively, limit dais 200 is supported, thus improves the impregnability of latch entirety.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
