Abstract
The utility model relates to a child safety seat headrest anticreep adjustment mechanism, including back, headrest and headrest lift adjustment mechanism, there are a plurality of gear grooves that set up vertically at the back of back, the gear groove cooperates with the gear pole, the gear pole is connected with the headrest through lift adjustment mechanism, the gear groove on bead mouth downward or slope to the back below extension formation anticreep portion; the utility model discloses be provided with anti-disengaging structure at the last port in gear groove, when the head rest produced great forward or ascending effort because inertia, owing to receive anti-disengaging structure's the shelves of hindering and ensure that the gear pole can not break away from gear groove to ensure that children's safety seat each direction intensity reaches the safety requirement of national regulation.
Description
Technical Field
The utility model relates to a children's safety seat technique, concretely a children's safety seat head rest anticreep adjustment mechanism.
Background
The child safety seat is necessary safety equipment when a baby and a child take a vehicle, and for the baby within the age of one week, the child safety seat needs to be reversely fixed; the back of the chair of this kind of fixed mode safety seat can be in case the effort that turns over forward when the vehicle bumps, the back of the chair also can produce the inertia that moves relative to the back of the chair, we can know when children's safety seat is colliding with the detection, because produce huge acceleration in the twinkling of an eye, children's safety seat's body receives ISOFIX device and stretching strap effect and only produces the upset of facing backwards, and the head rest all bears through gear pole and gear groove because inertia produces huge effort, under huge impact force, the gear pole receives gear groove upside and blocks the back and carry out backward movement and break away from the gear groove, consequently there is the potential safety hazard in current head rest adjustment mechanism, therefore many safety seats on the existing market can't pass through strict safety detection, do not have market access standard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a children's safety seat head rest anticreep adjustment mechanism is provided with anti-disengaging structure at the last port in gear groove, because inertia produces great forward or during ascending effort at the head rest, owing to receive anti-disengaging structure's the shelves of hindering and ensure that the gear pole can not break away from the gear groove to ensure that children's safety seat each direction intensity reaches the safety requirement of national regulation.
The following technical scheme is adopted for achieving the purpose:
the utility model provides a children's safety seat head rest anticreep adjustment mechanism, includes back, head rest and head rest lift adjustment mechanism, has the gear groove of the vertical setting of a plurality of at the back of back, and gear groove and gear lever cooperation, gear lever pass through lift adjustment mechanism and are connected its characterized in that with the head rest: the upper edge opening of the gear groove extends downwards or obliquely backwards and downwards to form an anti-falling part.
The gear groove is longitudinally widened, the longitudinal width of the gear groove is larger than the diameter of the gear rod, the upper edge of the gear groove downwards forms an anti-falling part, and the difference between the longitudinal size of the gear groove and the longitudinal size of the anti-falling part is equal to or slightly larger than the diameter of the gear rod.
The utility model discloses when bumping, the head rest removes the top in gear groove from gear groove bottom with the gear pole earlier under the inertia effect, because the utility model discloses bead downwardly or to the rear below extension formation anticreep portion on the gear groove, even the effort is huge, the gear pole also can not break away from the gear groove to avoid the gear pole to break away from the groove and cause the thing that the head rest fled from the back top to take place, ensure that children's safety seat reaches the safety requirement that the trade forces the regulation.

fig. 2 is a schematic structural diagram (ii) of the present invention;
FIG. 3 is a schematic view of the structure of the gear lever and the gear groove;
fig. 4 is a schematic structural view of the gear lever and the gear groove of the present invention.
Detailed Description
As shown in fig. 1-4, a children's safety seat headrest anticreep adjustment mechanism, including back 1, headrest 2 and headrest lift adjustment mechanism 21, there is the gear groove 11 of the vertical setting of a plurality of at the back of back 1, gear groove 11 and the cooperation of gear pole 3, gear pole 3 is connected with headrest 2 through lift adjustment mechanism 21, gear groove 11 vertically widen, the diameter that the vertical width in gear groove 11 is greater than the gear pole, gear groove 11 go up the bead and form anticreep portion 12 downwards, the difference of the vertical size of width and anticreep portion 12 of the vertical line size in gear groove 11 is equal to or is slightly greater than the diameter of gear pole 3.
The utility model discloses vertically widen the gear groove, like this when bumping, the head rest removes the top in gear groove with the gear pole from gear groove bottom under inertial action earlier, because the utility model discloses bead downwardly extending forms anticreep portion on the gear groove, even the effort is huge, the gear pole also can not break away from the gear groove to avoid the gear pole to break away from the groove and cause the thing that the head rest fled from the back top to take place, ensure that children's safety seat reaches the safety requirement that the trade forces the regulation.
The structure adopts a structure of widening the gear groove, the gear groove can not be widened in practical application, the upper edge opening of the gear groove is provided with the anti-falling part which extends towards the rear side and the lower side in an inclined way, and the distance between the anti-falling part and the lower edge opening of the gear groove is not less than the diameter of the gear rod; however, this structure is not favorable for the normal operation of the shift lever, and the actual effect is not as good as that of the first embodiment.
Claims (2)
1. The utility model provides a children's safety seat head rest anticreep adjustment mechanism, includes back, head rest and head rest lift adjustment mechanism, has the gear groove of the vertical setting of a plurality of at the back of back, and gear groove and gear lever cooperation, gear lever pass through lift adjustment mechanism and are connected its characterized in that with the head rest: the upper edge opening of the gear groove extends downwards or obliquely backwards and downwards to form an anti-falling part.
2. The headrest anti-release adjusting mechanism of the child safety seat as claimed in claim 1, wherein: the gear groove is longitudinally widened, the longitudinal width of the gear groove is larger than the diameter of the gear rod, the upper edge of the gear groove downwards forms an anti-falling part, and the difference between the longitudinal size of the gear groove and the longitudinal size of the anti-falling part is equal to or slightly larger than the diameter of the gear rod.
