Frame stretchable adjusting mechanism of child safety seat

Abstract

The invention discloses a frame stretchable adjusting mechanism of a child safety seat. The frame stretchable adjusting mechanism comprises a fixed frame and a sliding frame which can move longitudinally on frame guide rails. Stretchable rods are arranged on the two sides of the sliding frame, insertion openings are formed in the front ends of the stretchable rods, an adjusting rack is further fixedly arranged on the sliding frame, a tooth groove is formed in the adjusting rack and an opening of the tooth groove faces toward front upward side. An air spring is arranged on the fixed frame and provided with a stretchable end, the stretchable end is connected to the sliding frame and can push the sliding frame to move front and back, a clamping pin is transversely arranged on the fixed frame and can rise and fall, the clamping pin is driven by a connecting rod to move up and down, and the two ends of the clamping pin are connected with the fixed frame through a tension spring. By the adoption of the structure, the stretchable adjusting function of a frame is achieved through matching of the air spring and the clamping pin and the adjusting rack. The frame stretchable adjusting mechanism is simple, reasonable and compact in structural arrangement, easy and convenient to adjust and reliable in using performance.

Description

[0001] technical field [0002] The invention relates to an accessory part of a child safety seat, in particular to a telescopic adjustment mechanism for a child safety seat frame Background technique [0003] Child safety seats are very popular as a tool for children to travel.
