Embodiment Construction

[0007] 1. Open the door

[0008] After the control part of the lock is separated from the crank [1], under the action of the hand or the spring accumulator, the crank [1] rotates an angle, and the bolt [3] is pulled by the crank [1] through the connecting rod [2] Make a straight line to withdraw from the door frame movement along the slideway [4] to reach the door opening position.

[0009] 2. Close the door

[0010] Operate the handle on the door, so that the rotation of the handle drives the crank [1] inside the door or the inside of the door to rotate an angle (opposite to the rotation angle when the door is opened), and the bolt [3] is on the crank [1] through the connecting rod [2]. Under the promotion of the pusher, make a linear locking motion along the slideway [4] to reach the closed door position.

Abstract

Present invention discloses a safety door bolt mechanism. It contains crank rotation in said mechanism, uniformity or no uniformity distributed n>=2 number of door bolt along single side or two sides of door edge on right and left direction of door, under crank push and pull action, the door bolt making locking and unlocking movement to realize the door open and close. Said safety door bolt mechanism increases breaking door hardness, effectively raise overall strength of door and safety, and even if at high temperatures of hundred of degree, said door still can be smoothly opened.

Description

(1) Technical field [0001] The safety bolt mechanism is the field of door locks involved in life and property safety precautions in people's lives. (2) Background technology [0002] For the production technology of anti-theft doors, although people have made repeated efforts over the years, there are still many unsatisfactory places, such as traditional doors and anti-theft doors on the market. Cloth, uneven force, poor damage resistance. According to reports from Beijing Letter and Beijing Daily from September 13th to September 14th, 2005: Beijing Quality Supervision Bureau has inspected many anti-theft doors in Beijing, and more than half of the anti-theft doors are not anti-theft. Locks are particularly prominent. (3) Contents of the invention [0003] This is a safety bolt mechanism in which the force transmission point is scattered and the force is uniform for the door as a whole, and the bolt is controlled by a crank connecting rod. The crank [1] connecting rod [...
