Abstract
The invention relates to an emergency door lock triggering device, which comprises a pin remover which is arranged on a head jamb, a lock rod which is arranged on one end of an emergency door and can be extended out of the top end of the emergency door and a rotating plate which is arranged on the top end of the emergency door and is rotated around a central shaft, and the rotating plate is provided with a first gap where a pin remover fingers in and a second gap which is needed when the lock rod is in a locking state.
Description
Technical field
The present invention relates to a kind of lock trigger mechanism, be specifically related to the emergent door lock trigger mechanism of safety door.
Background technology
Escape door is an important component part of station safety doors such as subway.Escape door is passway for escaping or an occasional passage in particular cases in case of emergency.In order to ensure safety, escape door should meet the following conditions: when opening internally, without key, open easily, the personnel that are beneficial to withdraw rapidly; When opening, preferably need use key, prevent that unrelated person from getting into from the outside.Be to realize the emergency function of escape door, it requires escape door can discharge fully at the state hour locking lever of closing the door, and effectively, eject fully, guarantees that door is in locking state; Can compress fully at the door opening state hour locking lever and to be in arm-to-arm, and can not eject by mistake, guarantee not scrape, bump against and damage ground or doorframe, guarantee simultaneously to close the door smoothly.
Summary of the invention
The technical problem that the present invention will solve is that the last defective to prior art provides a kind of emergent door lock trigger mechanism.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of emergent door lock trigger mechanism; Comprise the finger that is arranged on the head jamb; Be arranged on emergent door leaf one end and can stretch out the locking bar on said escape door top; Be arranged on the rotating disk that rotate around central axis on the escape door top, said rotating disk is provided with said first breach and the said locking bar that said finger stretches into and is in the lock state the second required breach.
In emergent door lock trigger mechanism of the present invention, said rotating disk is " worker " font.
In emergent door lock trigger mechanism of the present invention, said rotating disk also is provided with extension spring, when emergent door lock trigger mechanism is opened in manual work; Said locking bar moves downward under the effect of the power of opening the door, when being lower than said rotating disk; Rotating disk will rotate around central axis under the extension spring effect, and then locking bar is fixed in the door leaf by Rolling disc lock; When opening the door, collided in any position that does not have lock body and ground or threshold, guarantee that emergency door release is smooth and easy.
Embodiment of the present invention, have following beneficial effect: a kind of emergent door lock trigger mechanism trigger mechanism is provided, makes can discharge fully, eject effectively, fully at the state hour locking lever of closing the door; Can compress fully at the door opening state hour locking lever and to be in arm-to-arm, and can not eject by mistake.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the cross-sectional view of emergent door lock trigger mechanism unlocking condition of the present invention;
Fig. 2 is the top plan view of emergent door lock trigger mechanism unlocking condition of the present invention;
Fig. 3 is the cross-sectional view of emergent door lock trigger mechanism locking state of the present invention;
Fig. 4 is the top plan view of emergent door lock trigger mechanism locking state of the present invention.
The specific embodiment
As shown in Figure 1; Cross-sectional view for emergent door lock trigger mechanism unlocking condition of the present invention; Vertical view in conjunction with emergent door lock trigger mechanism unlocking condition shown in Figure 2; Describe the structure of emergent door lock trigger mechanism of the present invention, emergent door lock trigger mechanism of the present invention comprises the finger 6 that is arranged on the head jamb, is arranged on the rotating disk 1 that rotate around central axis on the escape door top; Be arranged on the escape door top and can stretch out the locking bar 2 on said escape door top, said rotating disk 1 is provided with first breach that said finger 6 stretches into and said escape door and is in the said locking bar 2 of locking state and falls into second breach wherein.Its turntable 1 is " worker " font.Also comprise and make said rotating disk 1 extension spring 5 that rotates and the compression spring 4 that makes that locking bar 2 effectively ejects.
In conjunction with Fig. 1, Fig. 2 the process of closing the door is described.In the process of closing the door, emergent door lock trigger mechanism is along with the motion of escape door body, and the switch rotating disk 1 that is installed on the lock 3 bumps against the finger 6 that is fixedly mounted on the doorframe, and finger 6 withstands switch rotating disk 1, and along with the motion switch rotating disk 1 of escape door body rotates around the axle center.
As shown in Figure 3, be the cross-sectional view of emergent door lock trigger mechanism locking state of the present invention, in conjunction with the vertical view of emergent door lock trigger mechanism locking state shown in Figure 4.When the door pass put in place, along with the motion of escape door body, switch rotating disk 1 rotated; Turn to the position of locking bar 2; Then on the rotating disk 1 breach just in time above locking bar 2, then locking bar 2 the effect of compression spring 4 eject rapidly down and the lockhole of insertion doorframe in, door is effectively locked.
In the process of opening the door, locking bar 2 is pulled down to the switch rotating disk 1 time in the effect of manual release power, and switch rotating disk 1 rotates stirring under the effect with extension spring 5 of finger 6; Switch rotating disk 1 locks locking bar 2 fully, and at this moment, escape door is opened; Locking bar 2 does not stretch out door leaf; Simultaneously, the first notch alignment finger 6 of switch rotating disk 1 guarantees door locked reliable in action next time.
