Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example and be merely to illustrate and explain the present invention the application created on emergency exits, the purposes being not intended to limit the present invention.
As shown in figure 1, on a kind of mechanical lock of fast-escape door, the upper and lower door for being installed on fast-escape door, including handle
Mechanism, linkage and retaining mechanism；The handle mechanism is connected with linkage, the linkage and retaining mechanism phase
Even, wherein handle mechanism and linkage are fixedly connected with entrance door, and retaining mechanism and upper and lower door have connected, and lock
Tight mechanism is also flexibly connected to being provided between upper and lower door and car body and upper and lower door.
As shown in figures 1 to 6, the handle mechanism includes handle 12, handle base 15, torque spring 16, individual gears 17, half
Gear 18, micro-machine 19, the linkage include connecting rod 6, slide rail 11, spring 14, lamellule 20, the retaining mechanism
Including rack 3, band alligator nail 4, Double-gear 5, rack spring 7, pin sleeve 8, fastening base 9, guide rail 10；The handle base 15
It is connected with entrance door 1, handle 12 is connected with handle base 15, and torque spring 16 and individual gears 17, institute are connected with the handle 12
State micro-machine 19 to be connected with handle base 15, the micro-machine 19 is connected with half gear 18, half gear 18 and monodentate
Wheel 17 is engaged；The middle part of connecting rod 6 passes through handle base 15, and the middle part of connecting rod 6, which is provided with the right side of aperture, aperture, lamellule 20,
The end of handle 12 has projection 21 to block the aperture in the middle part of connecting rod 6；The both sides of connecting rod 6 are connected with spring 14, the spring
14 are connected with slide rail 11, and the slide rail 11 is connected with entrance door 1；The retaining mechanism is symmetrically arranged on handle mechanism,
The structure of its side is：The fastening base 9 is connected with exit door 2, and guide rail 10 and a pin are fixed with the fastening base 9
Nail set 8, the lower end of the fastening base 9 connection rack spring 7, the rack spring 7 is connected with the lower end of rack 3, on the rack 3
There is the projection 13 that the two ends of connecting rod 6 are inserted with aperture, aperture at end, and the rack 3 can move up and down along guide rail 10；Another pin
Set 8 is connected with entrance door 1, and a Double-gear 5 is arranged on the fastening base 9 being connected with exit door 2, and another Double-gear 5 is pacified
On the pin sleeve 8 being connected with entrance door 1, two Double-gears 5 are on a vertical curve, the rack 3 and two bidentates
External gear occlusion in wheel 5, is cased with band alligator nail 4 in two pin sleeves 8 respectively, the band alligator nail 4 respectively with two bidentates
Internal gear occlusion in wheel 5, the end for following closely 4 with alligator is inserted in the doorframe of car body, and upper and lower car door and car body are provided with this
Locking.There is certain gap between the internal-external gear of the Double-gear 5.
When a fault occurs, driving method is according to circumstances selected, selects manually opened in the extreme circumstances, then the handle
12 after half-turn is turned over, and the torque spring 16 can prevent handle 12 from turning over head, and now the projection 21 of the end of handle 12 is touched
Encounter lamellule 20, lamellule 20 turns over head prevented also from handle 12, at this moment the projection 21 of the end of handle 12 can lead to
The hole at the middle part of connecting rod 6 is crossed, the connecting rod 6 can be in the presence of the spring 14 of stretching along slide rail 11 to the side close to entrance door 1
