1 to Fig. 3 door ladder of the present invention unification landing gate sequence control mechanism is described in further details with reference to the accompanying drawing.
The present invention provides a kind of ladder unification landing gate sequence control mechanisms, may include first rotating shaft 1, arc rocker arm
2, gap rocker arm 3, the second shaft 4, pull rod 5 and rolling pin 6 etc..
Specifically, one end of first rotating shaft 1 is connect with boarding door handle, is provided at the center location of arc rocker arm 2
First through hole 11, first rotating shaft 1 are fixedly connected far from one end insertion first through hole 11 of boarding door handle with arc rocker arm 2.Separately
Outside, circular arc one end of arc rocker arm 2 is provided with ears structure, and symmetrically offers through-hole in ears structure, in ears structure
Portion is provided with arc groove, and the length of rolling pin 6 is greater than the integral thickness of the ears structure of arc rocker arm 2, and rolling pin 6 exists through setting
In the through-hole of the ears structure of arc rocker arm 2.There are many be fixedly connected with mode, this reality to rolling pin 6 with the ears auricle of arc rocker arm 2
It applies in example, thread segment preferably is set at the both ends of rolling pin 6, rolling pin 6 is hinged in ears auricle by nut.When unlatching boarding
When door handle, shaft 1 is rotated, so as to drive arc rocker arm 2 to rotate.
Further, the middle part of gap rocker arm 3 is provided with gap slot rolling compatible with rolling pin 6, rolling pin 6 is in gap slot rolling
When middle movement, the cell wall of gap slot rolling is not blocked in the arc groove that the ears inside configuration of arc rocker arm 2 is arranged.Into one
Step, is provided with circular arc compatible with the circular arc of arc rocker arm 2 in the side of the cell wall of the close gap slot rolling of gap rocker arm 3
Section, wherein arc section compatible with 2 circular arc of arc rocker arm ensure that as the rotation rolling pin 6 of arc rocker arm 2 can be from gap
Movement in the gap slot rolling of rocker arm 3 is until abjection.The second through-hole 12 is offered in gap slot rolling upper end, the setting of the second shaft 4 exists
It in second through-hole 12 of gap rocker arm 3, rotate gap rocker arm 3 can around the second shaft 4.It is preferably logical second in the present embodiment
Bearing is fixedly installed in hole 12, then the second shaft 4 is rotatably arranged in the second through-hole 12 of gap rocker arm 3 by bearing, with
Realize that gap rocker arm 3 can be rotated around the second shaft 4.In addition, one end on gap rocker arm 3 far from arc section is provided with the
Three through-holes 13.
Further, the third through-hole 13 of one end of pull rod 5 and gap rocker arm 3 is hinged, and the other end and pressure relief opening lid mechanism connect
It connects.In the present embodiment, ears structure is preferably opened up respectively at the both ends of pull rod 5, then by the way that pin shaft is each passed through the one of pull rod 5
Another auricle of a auricle, third through-hole 13 or pressure relief opening lid mechanism and pull rod 5, then split pin is cooperated to lock, it realizes and draws
Bar 5 and gap rocker arm 3 and pressure relief opening lid mechanism it is hinged.
In door ladder unification landing gate sequence control mechanism of the invention, can also respectively arc rocker arm 2, gap rocker arm 3,
Lightening hole of different shapes is arranged in corresponding position inside pull rod 5 keeps element lighter for mitigating element quality.
The working principle of door ladder unification landing gate sequence control mechanism of the present invention is as follows: when opening boarding door handle, the
The rotation of one shaft 1 drives the arc rocker arm 2 being fixedly connected with first rotating shaft 1 to rotate, and the rolling pin 6 on arc rocker arm 2 is shaken in gap
Movement in the gap slot rolling of arm 3, drives gap rocker arm 3 to rotate around the second shaft 4, and gap rocker arm 3 drives shake with gap simultaneously
The hinged pull rod 5 of arm 3 moves, and pull rod 5 drives pressure relief opening lid mechanism connected to it to move, and pressure release lid is opened；Work as pressure relief opening
When lid fully opens, rolling pin 6 is deviate from out of gap rocker arm 3 gap slot rolling, at this time the circular arc of arc rocker arm 2 and gap rocker arm 3
The arc section of one end is tangent, and when arc rocker arm 2 continues to rotate, gap rocker arm 3 is then remained stationary, so that pressure release lid is maintained at
Opening state.Equally, when closing boarding door handle, first rotating shaft 1 is rotated, and arc rocker arm 2 is driven to rotate, arc rocker arm 2
On rolling pin 6 enter gap rocker arm 3 gap slot rolling in and move, drive gap rocker arm 3 rotated around the second shaft 4, gap
Rocker arm 3 drives simultaneously to be moved with the hinged pull rod 5 of gap rocker arm 3, and pull rod 5 drives the pressure relief opening lid mechanism movement of the other end, is let out
Lid is pressed to close.Wherein, pass through the cooperation of the circular arc of arc rocker arm 2 and the arc section of gap rocker arm 3 and rolling pin 6 and gap
The cooperation of slot rolling drives, and realizes pressure release lid and opens and keep it turned on, ensure that the safety in utilization of landing gate.
In conclusion door ladder of the present invention unifies landing gate sequence control mechanism, rotation boarding door handle, landing gate are realized
Pressure release lid is opened, and continues to rotate boarding door handle, pressure release lid is kept it turned on, remaining mechanism continues to move, pressure relief opening
Lid mechanism remains stationary.The functional requirement for meeting hatch door ensure that the safety that landing gate uses.The arrangement of mechanism is ingenious,
The control of hatch door mechanism sequentially-operating is realized, structure is simple, and element is light, easy to operate.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of protection of the claims
It is quasi-.
