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
Technical field
The present invention relates to a kind of appurtenances of child safety seat, specifically a kind of child safety seat framework lockout mechanism.
Background technology
Child safety seat is popular to people as the instrument of children's trip, on existing automotive seat, standard socket is arranged, framework is inserted on the seat by socket, then child seat be placed on framework and fix, lockout mechanism between existing child safety seat and framework, therefore because structure arranges unreasonablely, lock performance poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of structure and arranges rationally, the good child safety seat frame lock fixed structure of locking performance.
In order to solve the problems of the technologies described above, child safety seat framework lockout mechanism of the present invention, comprise the pair of side plates arranged on each latched position, the U-lag that locking bar is entered is arranged on side plate, the inboard of side plate is provided with the latch hook of approximate semiellipse shape, the middle part of latch hook is hinged on side plate by a jointed shaft, the side front end of latch hook is provided with one can be at latch hook along in the jointed shaft rotation process, sealing or open the hook portion of U-lag notch, also comprise a tie rod that is positioned at side plate one side, on tie rod, be provided with one and can be pressed over all the time the spacing preiection on the latch hook curved surfaces, on the arcwall face of latch hook rear end, be provided with a position-limited trough matched with spacing preiection, spacing preiection can enter in position-limited trough and latch hook can't be rotated when the hook portion of latch hook is sealed the U-lag notch.
The rear flank end of described latch hook is provided with a locating dowel pin, between locating dowel pin and side plate, is provided with an extension spring.
After adopting above-mentioned structure, due to side plate and jointed shaft being set, be hinged on the latch hook on side plate, cooperatively interact action in conjunction with the spacing preiection on tie rod by side plate and latch hook, locking bar well can be locked in the U-lag of side plate, guaranteed thus the reliability of locking, its structure arranges rationally, simple to operate, flexible movements, improved greatly reliability, good reset response is played in the extension spring arranged simultaneously, and its Reliability of Microprocessor is further improved, and has good promotional value.
