Description
Technical field
The present invention relates to be used for carrying children's trip, and it can be placed in the structure of the safety chair seats of car for children on the automotive seat, specifically is a kind of safety chair seats of car for children backrest angle regulating mechanism.
Background technology
The juvenile motor vehicle emergency seat is to carry the apparatus that children use when going on a journey for people, and it generally includes base and backrest, and its backrest generally can be regulated angle between itself and the base by angle regulator, to improve user's traveling comfort.The backrest angle regulating mechanism of existing safety chair seats of car for children also exists defectives such as operation inconvenience, complex structure, gear are insecure, reliability of service difference mostly.
Summary of the invention
Technical matters to be solved by this invention is, a kind of simple in structure, easy to operate, mechanism for adjusting backrest of children car safe armchair that reliability of service is good is provided.
Mechanism for adjusting backrest of children car safe armchair of the present invention includes base and backrest, the lower end and the base of backrest are hinged, the back side of backrest is equipped with one can be along the upper and lower mobile pull bar of backrest, and the rear end of pull bar is connected with handle, and the front end of pull bar is provided with horizontal shift finger; Be provided with the vertical gear plate that is fixedly mounted on the base in shift finger the place ahead, be placed with a plurality of gear grooves on the described gear plate from top to bottom, be connected with extension spring between shift finger and the base, the spring force of extension spring pulls to shift finger in the gear groove; Also have a bracing frame at the back side of backrest, the upper end of bracing frame is hinged on the backrest by jointed shaft, and the lower end of bracing frame may be stuck in the draw-in groove on the base.
Also torsion spring can be installed between the jointed shaft of above-mentioned bracing frame and the bracing frame, the spring force of torsion spring makes bracing frame to the direction rotation of leaving backrest; But the base below the bracing frame is provided with the step of barrier support frame rotation, before draw-in groove is arranged on step.
The present invention is simple in structure, easy to operate, reliable in action, only need spur handle during use with regard to backrest free to rotate, the adjusting angle gear, and when backrest is fixed on the gear, support by bracing frame, improved the fastness of its gear greatly.
Description of drawings
Fig. 1 is the structural representation of the present invention under backrest fell state;
To be the present invention lift structural representation under the state at backrest to Fig. 2.
The specific embodiment
As shown in the figure, this mechanism includes base 1 and the backrest 2 that is hinged, the pull bar 3 that is arranged on the back side of backrest can overcome extension spring 5 under handle 4 pulling spring force moves to the back upper place, the lower end of pull bar is provided with horizontal shift finger 6, shift finger the place ahead is provided with the gear plate 7 that is fixed on the base, and the gear plate is provided with and shift finger 6 cooresponding a plurality of gear grooves 8.
State shown in Figure 1 is the state that backrest fell, when needs are regulated backrest angle, to back upper place pulling handle 4, can make the shift finger 6 of pull bar 3 lower ends leave gear groove 8, at this moment can rotate backrest upwards lifts, the bracing frame 9 at backrest back side jointed shaft 11 around the upper end under the effect of torsion spring 10 rotates, when turning to step 12 positions on the base, the bracing frame lower end is blocked, if at this moment the backrest adjusted is to required angle, then can unclamp handle, shift finger 6 springs under the effect of extension spring 5 in the gear groove 8 of corresponding position, and bracing frame 9 lower ends also are stuck in the draw-in groove 13 on the base, make backrest stable support (as shown in Figure 2) on certain angle position.
When needs fell backrest again, the operator can one pulls moving handle 4 and upwards lifts backrest, and the another hand is turned up bracing frame 9, made its lower end break away from draw-in groove, at this moment just backrest can be fallen to position shown in Figure 1.
