Swinging-block type child seat safety buckle for automobile

Abstract

The invention relates to a swinging-block type child seat safety buckle for an automobile, mainly comprising a buckle pulling main body and inserting pieces matched with the buckle pulling main body and can be inserted in and pulled out from the buckle pulling main body, wherein the buckle pulling main body comprises an upper cover, a lower cover, a button and a buckle pulling core body; the buckle pulling core body comprises an upper cover plate, a lower cover plate, a locking piece arranged on the lower cover plate, a left swinging block, a right swinging block, a left torsion spring, a right torsion spring and a top spring; and the locking piece pushes against or loosens the left swinging block and the right swinging block so that the left swinging block and the right swinging block get in a pushing or separated state with the button. In the invention, the locking piece pushes against middle lugs corresponding to the left swinging block and the right swinging block so that inserting hooks of the inserting pieces can be buckled with upper concave openings corresponding to the left swinging block and the right swinging block so as to realize locking of the safety buckle; or the locking piece pushes against lower lugs corresponding to the left swinging block and the right swinging block so that the concave openings corresponding to the left swinging block and the right swinging block release the inserting hooks of the inserting pieces so as to realize the release of the safety buckle. The swinging-block type child seat safety buckle has simple and compact structure and few linking pieces and is convenient to manufacture and use;, the matching structure of all components is stable and the locking is sensitive and hardly loosens or falls off, therefore the use safety performance is high.

Description

technical field [0001] The invention relates to a safety buckle for a seat, in particular to a safety buckle for a pendulum-type car child seat. Background technique [0002] With the improvement of living standards, families buy more cars, drive more and more, and the proportion of children riding in cars increases, so it is an urgent problem to be solved to ensure children's safety. In order to improve the safety of children riding in cars, safety seats are usually added to the car, and children are fixed in the safety seat through safety buckles. The safety buckles used on traditional car child seats are generally complex in structure and have many components. During the fastening, locking and releasing process of the buckle, the linkage of each component is cumbersome, the fastening strength and safety performance are low, the safety buckle is easy to fall off, and there are potential safety hazards for children riding in the car.
