Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
It applies example and is 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, a kind of mechanical lock of fast-escape door, is installed on the upper and lower door of fast-escape door, including handle
Mechanism, link mechanism and retaining mechanism；The handle mechanism is connected with link mechanism, the link mechanism and retaining mechanism phase
Even, wherein handle mechanism and link mechanism are fixedly connected with entrance door, and retaining mechanism and upper and lower door have connected, and are locked
Tight mechanism is also flexibly connected to providing 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 link mechanism include connecting rod 6, sliding rail 11, spring 14, lamellule 20, the retaining mechanism
4, Double-gear 5, rack gear spring 7, pin sleeve 8, fastening base 9, guide rail 10 are followed closely including rack gear 3, band alligator；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 on the handle 12
It states micro-machine 19 and handle base 15 is connected, the micro-machine 19 is connected with half gear 18, half gear 18 and monodentate
17 occlusion of wheel；Handle base 15 is passed through in the middle part of the connecting rod 6, and aperture is provided in the middle part of connecting rod 6, has lamellule 20 on the right side of aperture,
The aperture that 12 end of handle has protrusion 21 to block 6 middle part of connecting rod；6 two sides of connecting rod and spring 14 are connected, the spring
14 are connected with sliding rail 11, and the sliding rail 11 is connected with entrance door 1；The retaining mechanism is symmetrically arranged about handle mechanism,
The structure of one side are as follows: the fastening base 9 is connected with exit door 2, and guide rail 10 and a pin are fixed on the fastening base 9
Nail set 8,9 lower end of fastening base connect rack gear spring 7, and the rack gear spring 7 is connected with 3 lower end of rack gear, on the rack gear 3
There is aperture at end, the protrusion 13 at 6 both ends of connecting rod is inserted in aperture, the rack gear 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 mounted on the fastening base 9 being connected with exit door 2, another Double-gear 5 peace
On the pin sleeve 8 being connected with entrance door 1, two Double-gears 5 are on a vertical line, the rack gear 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 with alligator nail 4 are inserted into the doorframe of car body, provide upper and lower car door and car body 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, the then handle in the extreme circumstances
12 after turning over half-turn, and the torque spring 16 can prevent handle 12 from turning over head, and the protrusion 21 of 12 end of handle is touched at this time
Encounter lamellule 20, lamellule 20 turns over head prevented also from handle 12, and at this moment the protrusion 21 of 12 end of handle can lead to
The hole at 6 middle part of connecting rod is crossed, the meeting of connecting rod 6 is under the action of spring 14 of stretching along sliding rail 11 to the side close to entrance door 1
Sliding, the both ends protrusion 13 of the connecting rod 6 is exited from the hole of 3 upper end of both sides rack gear at this time, and the rack gear 3 then can be in stretching
Rack gear spring 7 moves under acting on along guide rail 10 down, and the rack gear 3 on the both sides is engaged with the external gear of two Double-gears 5,
Then the rack gear 3 on described every one side will drive two bidentates that it is engaged when moving down under the rack gear spring 7 of stretching acts on
5 rotation of wheel, the internal gear of every two Double-gear 5 are engaged with two band alligator nails 4 respectively again, then the rotation of Double-gear 5 can band
The dynamic doorframe for exiting emergency exits along pin sleeve 8 with alligator nail 4, achievees the purpose that release car door up and down and car body locks, and described
Rack gear 3 eventually moves to down along guide rail 10 under the action of the rack gear spring 7 of stretching and is only engaged a Double-gear 5, reaches
The purpose locked between car door up and down is released, so far emergency exits have unlocked completion.If selecting micro-machine in feasible situation
19 drivings, then the micro-machine 19 drives the rotation of half gear 18, then the bite strap by half gear 18 and individual gears 17
Dynamic individual gears 17 rotate, and since the individual gears 17 are connected with handle 12, then the rotation of individual gears 17 will drive 12 turns of handle
It is dynamic, achieve the purpose that 12 end of handle protrusion 21 can by 6 mider hole of connecting rod, at this time can the mechanical transfer of triggering following reach
To the purpose of unlock.
Structure of the invention is reasonable, can unlock in 2 seconds by using mechanical delivery device and spring, increases badly multiple
The reliability escaped under the conditions of miscellaneous, and ensure that the speed of enabling.Equipment operation is simply easy to maintain, can effectively ensure that accident is sent out
When raw when passenger personnel escape can smooth instant unlatching emergency exits, and realized by simple mechanical structure " one revolve it is more
Control "；When accident releases, car door can be closed by simplicity maintenance, realize the closing of car door.
