Safety buckle

Abstract

A safety buckle comprises a female buckle, a first male buckle and a second male buckle. Each male buckle is provided with a positioning hole. The female buckle comprises a female buckle, a first spring, a second spring, a first sliding block, a second sliding block, a pawl buckle, a push shaft, a third spring, a fourth spring and a push button. When the first male buckle and the second male buckle are simultaneously inserted into the female buckle, the first sliding block and the second sliding block are pushed by the first male buckle and the second male buckle to slide, the positioning holes of the first male buckle and the second male buckle are positioned under a pawl portion of the pawl buckle, so that the pawl portion of the pawl buckle is clamped into the positioning hole so as to lock the safety buckle. When the push button is pushed, the push button pushes an upwarp portion of the pawl buckle so that the pawl buckle rotates, and the pawl portion of the pawl buckle is separated from the positioning holes of the first male buckle and the second male buckle so as to unlock the safety buckle. The push button, the push shaft and the pawl buckle are arranged ingeniously, the male buckles can be prevented from loosening, connection soundness of the male buckles and the female buckle can be largely enhanced, and load opening force of the safety buckle can be reduced, thereby facilitating quick release of the safety buckle. The safety buckle has high practicality and safe usability.

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
