On the downside of plate in groove.
Further, described door-plate comprises door plate frame and some horizontally disposed mouldings, and door plate frame is rectangle frame
Frame and door plate frame corner are provided with rounded corners, and some mouldings are all horizontally disposed with and moulding two ends are fixed on door plate frame
Inner side, some mouldings are from top to bottom set in qually spaced in door plate frame.
Further, described self-locking plate end is wedge shape.
Further, described door-plate opposite side upper end is provided with the side plate being vertically arranged, and doorframe respective side Board position is fixed
Being provided with rocking bar limit switch and limit switch bearing, rocking bar limit switch is arranged on limit switch bearing, and limit switch props up
Seat is fixed on threshold, and when door-plate closes, side plate touches rocking bar limit switch.
Further, described door-plate opposite side is provided with rubber slab, rubber slab be fixed on door-plate side and rubber slab with
Doorframe opposite side is provided with rubber blanket.
This utility model compared with prior art, has the following advantages and effect: by from rising joining of hinge and self-locking plate
The incompatible automatic Guan Bi realizing handrail door, simple in construction, with low cost, and service life is longer, and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of gravity self-closing platform railing door of the present utility model.
Fig. 2 is the side view of a kind of gravity self-closing platform railing door of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are right
Explanation of the present utility model and this utility model is not limited to following example.
As it can be seen, a kind of gravity self-closing platform railing door of the present utility model, comprise doorframe 1, door-plate 2, certainly rise conjunction
Page 3 and self-locking plate 4, doorframe 1 is fixed on platform railing 5, and door-plate 2 side is by being hinged on doorframe 1 side, door from liter hinge 3
Plate 2 opposite side is provided with horizontally disposed locking bar 6, and self-locking plate 4 one end is hinged on doorframe 1 and is provided with on the downside of hinge point
Limited block makes to be under self-locking plate 4 normality level, is provided with, on the downside of self-locking plate 4 other end, the groove mated with locking bar 6, when
The when that door-plate 2 closing, locking bar 6 is positioned at groove on the downside of self-locking plate 4.
Door-plate 2 comprises door plate frame and some horizontally disposed mouldings, and door plate frame is rectangular frame and door plate frame
Frame corner is provided with rounded corners, and some mouldings are all horizontally disposed with and moulding two ends are fixed on inside door plate frame, some frames
Bar is from top to bottom set in qually spaced in door plate frame.Self-locking plate 4 end is wedge shape, and such door-plate 2 is under self gravitation effect
By automatically closing from liter hinge 3, the when of arriving self-locking plate 4 position, self-locking plate 4 end jack-up is made self-locking by locking bar 6
Plate 4 is rotated up along hinge point thus by locked for locking bar 6 in groove.Door-plate 2 opposite side upper end is provided with and is vertically arranged
Side plate 7, corresponding side plate 7 position of doorframe 1 is fixedly installed rocking bar limit switch 8 and limit switch bearing 9, rocking bar limit switch
8 are arranged on limit switch bearing 9, and limit switch bearing 9 is fixed on threshold 1, and when door-plate 2 closes, side plate 7 touches rocking bar
Limit switch 8, thus signal is passed to control station and notifies that staff's handrail door is closed.Door-plate 2 opposite side is provided with
Rubber slab 10, rubber slab 10 is fixed on door-plate 2 side and rubber slab 10 is provided with rubber blanket with doorframe 1 opposite side, thus
When end of door plate 2 closes, impulsive force buffers.
The when that a kind of gravity self-closing platform railing door of the present utility model using, door-plate 2 is opened under external force
Shi Zisheng hinge 3 is opened and is made door-plate 2 raise, and the gravitional force of door-plate 2 increases, and external force is removed the transform gravitational energy at back door and is
Door-plate 2 can be made to return to gravitional force minimum point, and door-plate 2 moves to closing direction.Can upspring when door-plate 2 arrives near doorframe 1
Self-locking plate 4, then self-locking plate 4 can return to horizontal level again under self gravitation formula effect, is pinned by door-plate 2.At this moment on door-plate 2
Side plate 7 can touch the rocking bar of rocking bar limit switch 8, transmit signal, door closes to allow staff know.
Above content described in this specification is only to this utility model example explanation.This utility model
Described specific embodiment can be made various amendment or supplements or use similar side by person of ordinary skill in the field
Formula substitutes, without departing from the content of this utility model description or surmount scope defined in the claims, and all should
Belong to protection domain of the present utility model.
