Description
Technical field
The present invention relates to staircase technical fields, more particularly to a kind of inlet of handrail safety guard.
Background technique
It is provided in the manufacture of GB16899-2011 escalator and moving sidewalk and installation safety standard 5.6.4.3:
The protective device of finger and hand should be set at the inlet of handrail at handrail steering end.
For above-mentioned requirements, mainstream escalator or moving sidewalk manufacturer mainly take two kinds of structure shapes at present
Formula:
1) handle inlet rubber uses rubber and hairbrush with deformation slot, handle inlet safety protection switch and handle inlet
Rubber directly contacts, the structure as shown in the utility model that Authorization Notice No. is CN203033623U；
2) handle inlet rubber uses monoblock type hard rubber, and handle inlet rubber backboard surrounding arranges multiple reset springs,
The structure as shown in the utility model that Authorization Notice No. is CN201193178Y.
For structure type 1), hairbrush and handle inlet rubber protrude handle inlet panel, and handle inlet safeguard protection is opened
Close directly with handle inlet rubber contact, since rubber resistance to deformation power itself is smaller.When having passenger's carry-on articles or the people that keeps a public place clean
When member accidentally touches handle inlet rubber, easily cause escalator or moving sidewalk out of service.
For structure type 2), multiple springs are arranged in handle inlet rubber backboard quadrangle, while safety switch is loaded on lower part.
But since backboard lacks fixed supporting surface, quadrangle spring pressure, resistance are inconsistent, and deflection can not everywhere for backboard
Control.When handle inlet is caught in finger or other objects, especially when handle inlet rubber parts two sides or top are caught in, the bottom of due to
Portion deforms very little, and there are the security risks of greater probability akinesia for safety switch.
Summary of the invention
Based on this, it is necessary to which the safety problem at inlet of handrail provides a kind of protection more comprehensively, and sensitivity is suitable

Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.
As Figure 1 and Figure 4, a kind of inlet of handrail safety guard, comprising: the peace at inlet of handrail is set
Shelve and be arranged in the safety switch 10 that handrail operating status is detected on mounting rack, further includes:
The entrance bolster 3 being arranged on mounting rack is swung, is equipped with handrail tape channel in the entrance bolster 3；
The trigger member 6 being spindle rotationally arranged on mounting rack, trigger member 6 are driven by rubber parts and are rotated to trigger safety open
Close 10；
Act on the reset element 9 between mounting rack and trigger member 6.
When (such as when thering is passenger's finger or other articles to be caught in inlet of handrail) handrail operation failure, entrance
Bolster 3 is swung under the promotion of foreign matter, and entrance bolster 3 swings the work for pushing trigger member 6 to overcome reset element 9
It firmly rotates, trigger member 6 triggers safety switch 10 to disconnect the safety return circuit of escalator or moving sidewalk, helps automatically
Ladder or moving sidewalk are out of service.
After Failure elimination, under the action of reset element 9, trigger member 6 resets, and trigger member 6 pushes entrance bolster 3 multiple
The safety return circuit closure of position, escalator or moving sidewalk, escalator or moving sidewalk restore to operate normally.
Entrance bolster 3 is using flexible materials such as rubber, and entrance bolster 3 is for filling at inlet of handrail
Gap is equipped with handrail tape channel in entrance bolster 3, when handrail is taken and wraps up in foreign matter and enter inside staircase, squeezes entrance buffering
3 deformation of part simultaneously pushes entrance bolster 3 to swing.
There is interaction relation between entrance bolster 3 and trigger member 6,6 turns of trigger member are pushed when entrance bolster 3 is swung
It is dynamic, after trigger member 6 resets under the action of reset element 9, entrance bolster 3 is pushed to reset.Safety switch 10 and entrance buffering
Part 3 is located at the two sides of trigger member 6, and when staircase operates normally, trigger member 6 is slow to entrance under the driving of reset element 9
Stamping 3 applies active force, which can push entrance bolster 3 to offset from by swing position, or in the position that freely swings
It sets.
By adjusting the active force that reset element 9 applies trigger member 6, the active force threshold of the adjustable rotation of trigger member 6
Value, when trigger member 6 is greater than force threshold by the active force of entrance bolster 3, trigger member 6 rotates.When passenger with
When body article or cleaning worker accidentally touch entrance bolster 3, since the active force applied to entrance bolster 3 is smaller, entrance
Bolster 3 swing to trigger member 6 apply active force it is also smaller, trigger member 6 will not rotate, so avoid malfunction cause
Escalator or moving sidewalk it is out of service.
In one of the embodiments, as shown in 1, Fig. 4, the one end of entrance bolster 3 far from trigger member 6 is to be fixed on peace
