Embodiment Construction

[0040] The structure of the present invention will be specifically described below in conjunction with the embodiments and the accompanying drawings.

[0041] Such as figure 1 As shown, a lock with safe opening and closing includes a buckle box 100 and a lock body 200, the buckle box 100 is located on the left side of the lock body 200, and the cover of the buckle box 100 adopts a transparent baffle to facilitate observation of the internal working conditions of the buckle box 100 The connection gap between the cover of the buckle box 100 and the buckle box 100 is filled with a dustproof pad, and the height of the buckle box 100 is the same as that of the lock body 200 .

[0042] Such as figure 2 As shown, the buckle box 100 includes a switch box 110 and a deadbolt box 120, and the switch box 110 includes a cable 111, a wiring hole 112, a wiring terminal 113, a base fixing hole 114, an insulating base 115, a contact 116, and a contact socket 117 And induction device 118, wh...

Abstract

The invention discloses a safely opened and closed lock which comprises a buckle box and a lock body, wherein the buckle box is positioned on the left side of the lock body. Under the condition that a safety door is closed, after the safety door is closed to an appropriate position, a lock tongue is inserted into a lock tongue hole, meanwhile a bolt is popped out under the action of a connecting rod, and is then inserted into a touch inserting hole, and a touch point can be pressed to an insulating base; under the condition that the safety door is opened, a handle is rotated downwards on the inner side of the safety door, the touch connecting rod and the lock tongue are driven by a middle connecting rod to move rightwards, and the bolt and the lock tongue are driven by the connecting rod to move rightwards, so that the opening state of the lock can be achieved, a well shaft safety door can be relatively rapidly and conveniently opened, the safety door can be closed under the conditions that the touch contacts the touch point, a first sensor works and a second sensor works, and the system security can be ensured; by adopting the safely opened and closed lock, the touch can be prevented from being adhered to the touch point, the situation that an elevator is powered on when the safety is closed but is not tightly locked can be avoided, and thus death and injury accidents such as shearing and falling can be avoided.

Description

technical field [0001] The invention belongs to the field of elevators, and in particular relates to a safe opening and closing lock. Background technique [0002] According to 5.2.2-5.2.2.2.2 of GB 7588-2003 "Safety Code for Elevator Manufacture and Installation", when the distance between landings is greater than 11 meters, it is necessary to set up a well safety door for fire and other accident rescue. The inspection door, shaft safety door and inspection trapdoor in the elevator passage are used to rescue passengers, and they are the doors of life for passengers when they are in danger. 11m), the passengers trapped in the car can be rescued as soon as possible. [0003] With the rise of high-rise buildings, elevators are gradually being widely used. As a vertical transportation tool, elevators are very convenient. In daily life, they are basically used every day. Due to improper operation of the equipment itself or human Accidents also happen from time to time. In par...
