Abstract
The invention discloses a headrest height adjustment mechanism for a child safety seat. The headrest height adjustment mechanism comprises press blocks, locking blocks and reset springs, wherein the press blocks located on the rear side of the chair seat back are connected with a headrest through connecting parts, a longitudinal channel allowing the connecting parts to penetrate through is formed in the seat back, clamp slots which are uniformly distributed and located at the side parts of the longitudinal channel are formed in the rear side of the seat back, the locking blocks are arranged on the inner sides of the press blocks, and the reset springs are located between the press blocks and the locking blocks. When the rest springs are in a stretching state, the locking blocks are clamped into the clamp slots, and the headrest is fixed on the seat back; the locking blocks are extruded by external force, the reset springs are compressed, and the locking blocks are separated from the clamp slots. The headrest height adjustment mechanism has the advantages that the pressing blocks are pressed by fingers, the reset springs are compressed, the locking blocks are moved out of the clamp slots, the press blocks are pushed to move up and down, the headrest moves up and down to the appropriate height position, after the locking blocks are loosened, the locking blocks are matched with the clamp slots under the action of the reset springs, and the headrest is fixed in the appropriate height.
Description
Technical field
The present invention relates to a kind of child safety seat, especially relate to a kind of height of headrest regulating mechanism of child safety seat.
Background technology
Usually inside the child safety seat chair back, headrest is provided with; height adjustment mechanism is provided with between headrest and the chair back; it is the height of headrest conveniently raising or reduce child's safety seat for vehicle; when child height grows tall; corresponding rising is also wanted in the head protection position of child seat, and children head is better protected.The head rest adjusting device of child safety seat or complicated structure in the market, otherwise it is very inconvenient to operate.The through hole mode having a kind of head rest adjusting device to adopt bolt to insert differing heights reaches the object regulating height, needs to lift on the other hand to rest the head on, and another hand carrys out stubborn bolt, and operation is wasted time and energy.Also having a kind of head rest adjusting device, in order to arrive object easy and simple to handle, needing the mechanism that supporting setting is comparatively complicated.Above-mentioned two kinds of height of headrest regulating mechanisms, all need both hands co-operating, just can complete rising or the reduction of headrest.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of one hand and gets final product complete operation, the height of headrest regulating mechanism of the simple child safety seat of structure.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of height of headrest regulating mechanism of child safety seat, comprise briquetting, locking block and retracing spring, the briquetting be positioned on rear side of the chair back is connected with headrest by attaching parts, the chair back offers the vertical passage passed for attaching parts, be provided with on rear side of the chair back and be positioned at vertical passage sidepiece well-distributed screens groove, described locking block is arranged at the inner side of briquetting, described retracing spring is between briquetting and locking block, under retracing spring is in extended configuration, locking block snaps in described screens groove, pillow holder is fixed on the chair back, external force extruding locking block, retracing spring is compressed, and locking block is separated with screens groove.
The further preferred version of the present invention: described screens groove is evenly distributed on the both sides of vertical passage.The setting of both sides screens groove, during locking block locking, structural stability is better.
The further preferred version of the present invention: the described chair back is provided with the longitudinal fluting for briquetting movement, the flange being provided with screens groove stretches in described longitudinal fluting, lateral channels is formed between flange and the cell wall of longitudinal fluting, described briquetting is provided with side plate, and described side plate stretches in described lateral channels.When briquetting moves in longitudinal fluting, the side plate of its both sides can play stable effect, and simultaneously lateral channels and coordinating between side plate, play the effect of guiding, structural stability when briquetting moves in longitudinal fluting is better.
The further preferred version of the present invention: described briquetting comprises connecting portion, pars intermedia and lower connecting portion, is provided with the cavity installing locking block, is provided with boss, described boss and described screens slot fit on front side of described locking block in pars intermedia.Upper connecting portion and lower connecting portion installation connecting element, by attaching parts, be fixed up headrest and briquetting.Locking block is arranged on pars intermedia, and when locking block and screens slot fit, structural reliability is better.
The further preferred version of the present invention: pars intermedia comprises top cover and the middle side with through hole, and described locking block comprises press section and positioning plate, and described positioning plate is positioned at inside side, and press section is exposed from described through hole.The effect of positioning plate prevents locking block from rocking, and press section is exposed from through hole simultaneously, points after stretching into from through hole, can exert a force to press section easily.
Compared with prior art, advantage finger of the present invention inwardly pressure-locks block, retracing spring compresses, locking block shifts out from screens groove, promotion briquetting moves up and down, and headrest is followed briquetting and moved up and down position to proper height, unclamps locking block, locking block under the effect of retracing spring with screens slot fit, pillow holder is fixed on suitable height.Structure of the present invention is simple, only needs one hand to complete height adjustment operation, operates very convenient.
