Abstract
A kind of passenger on public transport door safety device, including：Outer ring, transmission ring, inner ring, returning spring and bearing pin, it is characterized in that：Inner ring is fixedly connected with rotating shaft, and transmission ring is bolted with curved boom, and transmission ring and inner ring realize releasable connection using bearing pin and returning spring, while bearing pin extrudes inner surface always in the presence of returning spring.Simple structure of the present invention, it is easily achieved, the disengaging of curved boom and rotating shaft can be reliably realized, with practical value very high.
Description
Technical field
The invention belongs to traffic and transport field, more particularly to a kind of passenger on public transport door safety device.
City's witenagemot of China 85% selects bus as primary trip instrument according to statistics, in face of so big carrying capacity,
Bus emergency safeguard measure just seems particularly important, is worth carefully studying.
Domestic bus frequently with emergency protection measure have：Safety hammer, automatic-explosion device, fire extinguisher, atomizer and
Door pump stop valve.These measures from window escape, fire extinguishing and door escape account for, wherein in view of escape efficiency and
Secondary injury is avoided, door escape is preferred manner.Door escape needs press a pump stop valve to lay down opening/closing door of vehicle mechanism air pressure
Realization opens Door by Hand, but it has two big defects：First, if bus circuit breaks down, door pump stop valve can not be normal
Work, cannot lay down switching mechanism air pressure；Second, crowd cannot open passenger doors once squeezing get lodged in doorway outward.Can from above
, best mode outwards opens passenger on public transport door completely using independent system.
ZL201420557447.4 discloses a kind of device for outwardly opening passenger on public transport door, described that bus is original
Threaded connection at chute connecting rod be changed to can Quick release pin, when perform enabling signal when, mechanical part quickly to
Interior withdrawal pin so that car guide rail departs from door-plate, so as to realize that rotating shaft is outwards opened the door.The problem that this kind of structure is present is：Should
Patent does not solve to be connected due to curved boom and rotating shaft, and during disengagement, rotating shaft maintains static to move causes curved boom to maintain static, last passenger
The problem that door can not be outwardly opened completely.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided one kind can make independently of bus original system
The rotating shaft of bus becomes the mechanism being hinged with curved boom by being fixedly connected.When mechanism and can making what car guide rail and door-plate unclamped
When mechanism is used together, it is possible to achieve bus door complete external-open in emergency circumstances.
The technical solution adopted for the present invention to solve the technical problems is：Including outer ring, transmission ring, inner ring, returning spring
And bearing pin, it is characterized in that：Outer ring inside is curved profile.Transmission ring can be divided into upper and lower two parts, and upper part is cuboid,
Screwed hole is provided with, lower part is cylinder, is provided with shoulder hole.Inner ring lower section is provided with pin hole, and pin hole is blind hole.Bearing pin
It is multi-diameter shaft, thin shaft end carries out chamfering.The connected mode is fixedly connected for the inner surface of inner ring with rotating shaft, and transmission ring utilizes spiral shell
Pit is connected with curved boom, and transmission ring is connected with inner ring by shoulder hole thereon and pin hole.To realize shoulder hole and pin hole
Connection, it is necessary to the bolt device being made up of returning spring and bearing pin, returning spring is compressive state, and one head is against shoulder hole
Median surface on, other end is against on bearing pin, the thin shaft end of bearing pin through inner ring pin hole and transmission ring shoulder hole, in returning spring
In the presence of big end end face extrude the inner surface of outer ring always.The hop count of the inner surface contour curve and bearing pin, reply
The quantity of spring is consistent.
Outer ring rotating, bearing pin is driven outwards to eject during work, Internal and external cycle is separated.
The invention has the advantages that：
1st, the present invention has no effect on the use of bus under normal circumstances, and bus is opened has original system with closing
It is controlled；In case of emergency, outer ring rotating realizes that the curved boom of passenger on public transport door is hinged with rotating shaft by being fixedly connected change, when
Mechanism and when can be used together the mechanism that car guide rail and door-plate unclamp, it is possible to achieve bus door is in emergency circumstances
Complete external-open, practical value and application value are very high.
2nd, contacted by the big end end face of bearing pin and inner surface, form cam mechanism, a variety of fortune can be reached
Dynamic rule, quick response is simple compact, simultaneously because can be using multiple bearing pins, connection can be accomplished reliable and stable.

Specific embodiment
Below by embodiment and the structure to a kind of passenger on public transport door safety device of the invention and work with reference to accompanying drawing
Principle is described further.
In the present embodiment, the curved boom 9 of bus is set to become structure such as Fig. 1 institutes of the mechanism being hinged by being fixedly connected with rotating shaft 10
Show, mainly include：Outer ring 1, transmission ring 2, inner ring 3, returning spring 4 and bearing pin 5.
The structure of outer ring 1 is cam as shown in figure 1, internal have curved profile.Transmit ring 2 structure as shown in figure 3,
It is divided into upper and lower two parts, upper part is cuboid, is provided with screwed hole 6, lower part is cylinder, is provided with shoulder hole 7.It is interior
The structure of ring 3 as shown in figure 4, be provided with pin hole 8, pin hole 8 is blind hole below.The structure of bearing pin 5 is as shown in figure 5, be
Multi-diameter shaft, thin shaft end carries out chamfering.Device assembling mode is as follows：The inner surface of inner ring 3 is fixedly connected with bus rotating shaft 10, transmission
Ring 2 is connected using screwed hole 6 with bus pivoted arm 9, and transmission ring 2 is connected with inner ring 3 by shoulder hole 7 and pin hole 8.Such as Fig. 1
It is shown, to realize the connection of shoulder hole 7 and pin hole 8, it is necessary to the bolt device of returning spring 4 and the composition of bearing pin 5, returning spring
4 is compressive state, and one head is against on the median surface of shoulder hole 7, and other end is against on bearing pin 5, and the thin shaft end of bearing pin 5 passes through ladder
Hole 7 and pin hole 8, the big end end face in the presence of returning spring 4 of bearing pin 5 extrude the inner surface of outer ring 1 always.
When needing to make the curved boom 9 of bus mutually to be unclamped with rotating shaft 10 when being in an emergency, it is allowed to the external drive of outer ring 1
Rotate so that outer ring 1 is moved from inside to outside with the contact surface of bearing pin 5, and bearing pin 5 is protruding, final inner ring 3 takes off with transmission ring 2
Connection is opened, rotating shaft 10 becomes to be hinged with curved boom 9.
