safety buckle

Abstract

The safety buckle comprises a female buckle, a first male buckle and a second male buckle, and a positioning hole is arranged on the male buckle, and the female buckle includes a female buckle base, a first spring, a second spring, a first slider, a second Slider, claw buckle, pushing shaft, third spring, fourth spring and push button, when the first male buckle and the second male buckle are inserted into the female buckle at the same time, the first slider and the second slider are on the first male buckle and the second male buckle are pushed down and slide apart, the positioning holes of the first male buckle and the second male buckle are located directly below the claws of the claw buckle, so that the claws of the claw buckle snap into the positioning hole and lock the safety buckle; when pushed When the button is pushed, the push button pushes the upturned part of the claw buckle to make the claw buckle rotate, and the claw of the claw buckle escapes from the positioning holes of the first male buckle and the second male buckle to unlock the safety buckle. The push button, push shaft and claw buckle of the present invention are ingeniously arranged, which can not only prevent the male buckle from loosening, greatly strengthen the connection firmness of the male buckle and the female buckle, but also reduce the load opening force of the safety buckle, which is conducive to quick release and safety. The buckle is very practical and safe to use.

Description

【Technical field】 [0001] The invention relates to a safety buckle, in particular to a safety buckle for a child safety seat. 【Background technique】 [0002] Chinese patent application number: 201310600267.X discloses a safety buckle for children's car safety seats, including left and right inserts, upper and lower covers, buttons and buckle cores, and the lower parts of the left and right inserts are equipped with Hook, the hook is inserted into the cavity corresponding to the upper and lower covers and is in a state of corresponding insertion and locking or disengagement with the buckle core in the cavity. The upper cover is provided with a button for connecting the buckle core. The top block is elastically pressed against the insert and the pendulum clamp shaft is elastically snapped into the hook groove, which jointly restrains the locking and fastening and disengagement of the clamp shaft and the insert, and realizes the fastening of the safety buckle with a small force ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned inventions have many components and complex linkage actions, all of which can be fastened and released by single-sided inserts or male buckles, which affect the safety performance and flexibility of the safety buckle

In addition, when the existing safety buckle releases the safety buckle, its resistance increases, requiring the user to use greater force to release the safety buckle
