Brake unit starts.
Concrete operating principle is as follows:
During the child playing holds handrail and taken advantage of a situation and take to staircase gateway, finger can encounter rubber
Set, because rubber sleeve is soft and has elasticity, lower end is hatch frame again, and child will not be caused with rigid injury, general finger
Encounter foreign body will trained reflex to retract, it is to avoid the injury that finger is brought into.And have on lower end second opening of rubber sleeve
It is arranged at intervals with several electrically conductive elastic pieces, electrically conductive elastic piece is arranged in series in safety return circuit, and safety return circuit contact is arranged on rubber
In the middle part of gum cover and bottom, of short duration finger enters and will not culture contact connect, and does not affect the normal operation of staircase.If child exists
Do not take away after entering rubber sleeve, stretching into finger, compressing rubber covers so that rubber sleeve second opening ftractures at once,
Rubber sleeve is recessed upwards, will disconnect, timely first with the cracking of two panels rubber clack in immediate electrically conductive elastic piece
Electrically conductive elastic piece is not turned off, progressively stretching into finger, and rubber sleeve compression degree is bigger, causes the second opening to split degree
Bigger, the electrically conductive elastic piece of position will necessarily be made to disconnect, that is, safety return circuit disconnects, escalator drive mechanism power-off,
Described power supply disconnects and staircase brake unit starts simultaneously, and staircase moment brakes, and reduces braking distance and response time, arbitrarily
One electrically conductive elastic piece disconnects and safety return circuit all can be caused to disconnect, that is, is cut-off using the Purely mechanical of this stress formula step by step
Equipment, eliminates the SRTs such as signal transmission and the process of pc machine, effectively reduces the braking distance of staircase, general feelings
Under condition, child's finger has at least distance of 200mm can slip out of the hand before entering gateway, will before that is to say entrance gateway
Region out of danger, prevents the injury that staircase causes to human body in advance, and whole process is all mechanical mechanism, is not required to electricity consumption,
Without energy consumption, simple and reliable.
In technique scheme, described rubber sleeve 100 is combined by two panels arc rubber clack, rubber clack described in two panels

Drive mechanism power supply.
In technique scheme, described rubber sleeve 100 is in the Chinese red with warning function, endangers in this region of reminding passengers
Danger.
In technique scheme, the length of described rubber sleeve 100 is at least 200mm, gives passenger the sufficient response time
Come region out of danger automatically, electrically conductive elastic piece is disposed on the bottom of rubber sleeve, preferably distribution is arranged on rubber sleeve
Middle afterbody.
From the above mentioned, this device adopts the response protected mode of Purely mechanical, when have foreign body snap in handrail and step it
Between, when rubber sleeve stress reaches to a certain degree, automated to respond to, safety return circuit disconnects automatically, cut off staircase driving power supply, make simultaneously
Dynamic device starts, and the instantaneous band-type brake of staircase is shut down, and effectively prevent the injury accident to human body, and serves the work preventing in advance
With, reliability is high, and this device need not carry out information processing and action after reaction using pc machine, protects process much sooner,
Substantially moment stops ladder, and the protection device being controlled using pc machine stop that terraced process is longer, the injury causing apart from longer,
Meanwhile, easily caused by sensitivity, electrical signal intensity, interference and other reasonses using the protection device that pc machine controls and be failure to actuate
And misoperation, reliability is high, and the protection device of the present invention effectively increases the reliability of protection；On the other hand, the present invention
Protection device structure, setting and operation principle are simple, and the fully mechanical device protected according to stress size will not produce
Misoperation, it is failure to actuate, effective protection personal safety, protect step against damages simultaneously, and whole process, substantially without energy consumption, is
Producer saves cost.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in description and embodiment
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Realize other modification, therefore under the general concept being limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
