Abstract

The invention discloses a central control bolt. The central control bolt comprises a central pivot (2), a transmission mechanism (3) and a locking mechanism (4), wherein the central pivot (2) is mounted in a sub-fan body and does reciprocating motion between a locking-out position and a locking-in position under the action of operating force and restoring force in the opposite direction of the operating force; the transmission mechanism (3) is used for transmitting motion of the central pivot (2) to a push type panic bar spring bolt (6), and the push type panic bar spring bolt (6) is mounted on the sub-fan body in a vertical reciprocating motion manner; the locking mechanism (4) is arranged between the central pivot (2) and the sub-fan body and is used for locking the central pivot (2) between the locking-in position and the locking-out position; the locking mechanism (4) is provided with a sliding part (13) arranged on one of the central pivot (2) and the sub-fan body and an annular guide structure arranged on the other of the central pivot (2) and the sub-fan body, and the sliding part (13) cooperates with the annular guide structure to keep the central pivot (2) at the locking-out position and the locking-in position; and a one-way non-return mechanism is arranged between the sliding part (13) and the annular guide structure.

Description

technical field [0001] The invention relates to the field of anti-theft doors, in particular to a central control latch. Background technique [0002] For security doors installed at home, when the width of the door opening is large, the door leaf is designed in the form of a large and a small mother-in-law for the overall beauty of the door. In the existing security doors of the parent-compartment fan type, the sub-doors are usually limited and fixed by means of two bolts symmetrically arranged at the upper and lower ends. When opening the sub-door, both door bolts need to be opened, and when closing, the two door bolts need to be inserted respectively, which is cumbersome to operate. And because the two bolts are arranged up and down, it is necessary to bend down or squat down when operating the lower bolt, which is not easy for the elderly to complete the operation; if the upper bolt is not tall enough and needs to be completed with tools such as stools, it is difficult ...
