Abstract
The utility model relates to a child safety seat headrest adjusting device which comprises a headrest and a main body, wherein the headrest is connected to the main body in a lifting and limiting manner up and down, the main body is symmetrically provided with two shift grooves from top to bottom, two adjusting cards which are respectively positioned and placed in the two shift grooves are symmetrically arranged on the back of the headrest, the lower parts of the two adjusting cards are connected to the headrest, and the upper parts of the two adjusting cards are elastically locked in the two shift grooves toward the outsides of the two shift grooves, respectively. A gear shaft slide block is arranged between the headrest and the main body, and is elastically connected to the headrest along the direction of the main body up and down. The lower part of the gear shaft slide block corresponds to the upper gap on the upper parts of the two adjusting cards. The shift of the headrest is adjusted up and down by elastic adjustment of the adjusting cards and the shift grooves between the headrest and the main body, and the gear shift slide block is matched to lean the adjusting cards in the shift grooves to fix the shift, so that the device is simple in structure, convenient to manufacture and use, stable to adjust and long in service life.
Description
Technical field
The utility model relates to child safety seat, is a kind of control apparatus for up-down adjustment infant safety chair headrest specifically.
Background technology
Vehicle-mounted restraining system for children is a kind of children safety system with car colleague, is mainly child safety seat seat assembly, effectively the traffic safety of child protection.Normal children's safety seat is comprised of base, backrest and head rest, and base is used for connecting automobile ISOFIX and is fixedly connected with, and backrest and head rest are respectively used to children back and head to support.Traditional children safety seat is formed in one or fixing package assembly, cannot regulate, because the growth of child development phase is very fast, the child safety seat that must often change larger specification, model could meet operating needs, virtually increased customer using cost, poor for applicability.
The vehicle-mounted child automotive safety constrained system headrest adjusting device that applicant is 201220180911.3 in the patent No. of first to file, and the patent No. is
2a kind of vehicle-mounted child automotive safety constrained system headrest adjusting device of 01220180874.6, adopt the commutation of head rest up-down adjustment to drive slide rail tooth or the corresponding tooth bar of locking lever or the flexible adjusting that realizes head rest upper-lower position of gear shift hole horizontal to fix, but its commutation drive disk assembly is more, complex structure, manufacturing cost is high.
Summary of the invention
In order to solve in prior art headrest adjusting device complex structure on child safety seat, the high deficiency of manufacturing cost, it is a kind of simple in structure that the utility model provides, modification stability, long service life, the infant safety chair headrest control apparatus manufacture, use cost being low.
The technical solution adopted in the utility model is: a kind of infant safety chair headrest control apparatus, comprise head rest and body, head rest is that oscilaltion is spacing to be connected on body, on body, be arranged with two shift slots from top to bottom, its technical characterstic is that described head rest back is arranged with respectively location and is placed in two in two shift slots and regulates card, two regulate card bottom to be connected in head rest, and two regulate card top respectively in two shift slot outer elastic clamping two shift slots; Between described head rest and body, be provided with gear shift slide block, gear shift slide block is connected on head rest along body above-below direction elasticity, and gear shift slide block bottom corresponding two regulates card upper gap.
Described head rest back is provided with a plurality of joint pins, and described body is provided with fluctuating orbit from top to bottom, and joint pin cross-under fluctuating orbit is limited in fluctuating orbit by plug.
Described gear shift slide block is provided with a plurality of connecting bores, and connecting bore is limited in shift slot by plug or gear shift piece through tie bolt cross-under shift slot.
Described gear shift slide block is provided with a plurality of connecting bores, and connecting bore is limited in fluctuating orbit by plug or gear shift piece through tie bolt cross-under fluctuating orbit.
Described gear shift slide block is provided with drag hook, and head rest is provided with lower draw-bar, between upper and lower hook, through spring, connects.
Described gear shift slide block top is provided with the gear shift handle with safe tape.
Adopt technique scheme, the beneficial effects of the utility model are: when head rest regulates, pull gear shift handle, the corresponding two adjusting card upper gap that depart from gear shift slide block bottom, now pull head rest, two of head rest back regulates card top to be subject to the inside elastic shrinkage of many retaining grooves of shift slot structure antagonistic force, head rest can be with pulling up-down adjustment on shift slot, be adjusted to and need behind position, unclamp gear shift handle, gear shift slide block bottom resets and snaps in two adjusting card upper gap under the elastic reaction of upper hook lower draw-bar on spring and body, now gear shift slide block lower limit two regulates the inside elastic shrinkage in card top, regulate the card top cannot up-down adjustment in shift slot, adjusting position is fixedly realized head rest and is regulated location, the adjusting of head rest and fixing directly by head rest and body through regulating card and shift slot to realize, adjustment structure is simple, easy to operate, and after gear is fixing, regulate the relative shift slot of card to shrink, the rigid clamping of gear shift slide block, gear is fixed.
The utility model adopts between head rest and body and regulates through regulating card and shift slot flexible adjustment to realize lower gear on head rest, coordinate gear shift slide block that rigid the holding out against of adjustings card realized to gear and fixed in shift slot, it is simple in structure, manufacture, easy to use, modification stability, long service life.
