Frame locking mechanism of child safety seat

Abstract

The invention discloses a frame locking mechanism of a child safety seat. The frame locking mechanism comprises a pair of side plates arranged on each locking position, a U-shaped groove is formed in the side plates, and a lock rod can enter the U-shaped groove. A Lock hook is arranged on the inner sides of the side plates and approximates a semi-ellipse shape. The middle of the lock hook is hinged to the side plates through an articulated shaft, a hook part is arranged at the side front end of the lock hook, and the frame locking mechanism further comprises a stay. A limit protrusion is arranged on the stay and can always lean against the arc-shaped surface of the lock hook, a limit groove is formed in the arc-shaped surface of the rear end of the lock hook and matched with the limit protrusion, and when the hook part of the lock hook closes a notch of the U-shaped groove, the limit protrusion can enter the limit groove and enables the lock hook to be incapable of rotating. By the adoption of the structure, locking reliability is guaranteed, the structural arrangement is reasonable, operation is easy, movements are flexible, the reliability is greatly improved, meanwhile, an arranged tension spring plays a role in resetting well, reliability of the movements is further improved, and the frame locking mechanism has very good popularization value.

Description

[0001] technical field [0002] The invention relates to an accessory part of a child safety seat, in particular to a frame locking mechanism of the child safety seat. Background technique [0003] Child safety seats are very popular as a tool for children to travel. There are standard sockets on the existing car seats. The frame is inserted on the seat through the socket, and then the child seat is placed on the frame and fixed. The locking mechanism between the special child safety seat and the frame has poor locking performance due to unreasonable structural settings. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a child safety seat frame locking structure with reasonable structure and good locking performance. [0005] In order to solve the above-mentioned technical problems, the child safety seat frame locking mechanism of the present invention includes a pair of side plates provided at each locking posit...
