Description
Technical field
This utility model belongs to the important component part of a kind of elevator, especially relates to a kind of elevator door
Link plate anti-drop device.
Background technology
Existing elevator door when mounted, in order to prevent elevator door from coming off under external force collision, therefore exists
Increase bending anticreep flanging bottom the rail of layer door base plate, layer door hanging plate is provided with regulation wheel, anticreep
Flanging coordinates spacing regulation wheel, it is achieved anticreep requirement.Layer door base plate increases anticreep flanging, material
Require to increase on the basis of former.As it is shown in figure 5, normal operating conditions flanging 10 has with regulation wheel 20
Gap, does not rubs；When elevator door is under external force effect of impact power, regulation wheel 20 and anticreep flanging 10
Block, prevent link plate from dropping, to prevent layer door-plate from dropping；As shown in Figure 6, regulation wheel is rolled over anticreep
Gap, limit is the least, the angle of only about 1.5 ° when encountering, rail position upper gap 4.1mm, bottom
There is 4.8mm in gap, and the link plate perpendicularity of assembling relatively requires relatively stricter, and assembling perpendicularity is bad just
Can produce noise, installation requirement is high.
Utility model content
The purpose of this utility model is to provide a kind of elevator door link plate anti-drop device, it is possible in solution
State at least one in problem.
According to an aspect of the present utility model, it is provided that a kind of elevator door link plate anti-drop device, bag
Including the first fastener and the second fastener, the first fastener is arranged on layer door base plate, the second fastener
Being arranged on layer door hanging plate, the first fastener is provided with first anti-tripping, and the second fastener is provided with second to be prevented
Threading off, first is anti-tripping and second anti-tripping can be interlocked.
The beneficial effects of the utility model are: the first fastener is arranged on layer door base plate, therefore, subtracts
Lack the material usage of layer door base plate, and without processing disconnecting prevention structure on layer door base plate, simplified and produce,
Improve efficiency；It is provided with the first fastener and the second fastener so that when elevator door link plate is by external force,
First is anti-tripping and second anti-tripping be interlocked, and effectively prevent link plate and drops and then prevent elevator layer
Door comes off, it is ensured that the safety of use.
In some embodiments, the first fastener is L-shaped.Thus, it is possible to facilitate the first fastener
Molding, and it is easy to the first fastener and the second fastener is interlocked.
In some embodiments, when first anti-tripping with second anti-tripping be interlocked time, the first buckle
The maximum of part and the second fastener angle between the two is 3.2 °.Thus, when layer door is by bigger
During external force collision, the first fastener and the second fastener angle between the two can reach 3.2 °, i.e.
When the first fastener and the second fastener exist larger gap so that both need from fastening to friction
Wanting the flip angle of 3.2 °, therefore, rail position upper gap can reach 4.3mm, underclearance
5.9mm can be reached so that between layer door hanging plate and rail, have enough spaces, relatively the extension of assembling
Plate perpendicularity requires relatively low, will not wipe easily and touch and produce noise.
In some embodiments, the second anti-tripping top being positioned at the second fastener.Thus, convenient
Second anti-tripping and the first anti-tripping fastening.
In some embodiments, the first fastener is provided with the first installing hole.Thus, the first card is facilitated
Fastener is arranged on layer door base plate.
In some embodiments, the second fastener is provided with the second installing hole.Thus, the second card is facilitated
Fastener is arranged on layer door hanging plate.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Referring to figs. 1 through Fig. 4: elevator door link plate anti-drop device, including the first fastener 1 and the second card
Fastener 2, the first fastener 1 is arranged on layer door base plate 3, and the second fastener 2 is arranged on layer door and hangs
On plate 4, the first fastener 1 is provided with first anti-tripping 11, and it is anti-tripping that the second fastener 2 is provided with second
21, first anti-tripping 11 and second anti-tripping 21 can be interlocked.Wherein, the first fastener 1 is opened
Being provided with the first installing hole, the first fastener 1 is fixed with layer door base plate 3 bolt by the first installing hole；
Second fastener 2 offers the second installing hole 22, the second fastener 2 by the second installing hole 22 with
Layer door hanging plate 4 bolt is fixed.
In actual use, the installation of the first fastener 1 for convenience, on the rail of layer door base plate
Perforate so that the first fastener 1 is fixed on layer door base plate 3 after this hole passes.Elevator door closes
When closing, the second fastener 2 on layer door hanging plate 4 interlocks with the first fastener 1 on layer door base plate 3
Close.When elevator door is under normal condition, the most not by under external force collision active state,
One anti-tripping 11 and second anti-tripping 21 fastens, but both do not contact, and there is gap, thus the
One fastener 1 and the second fastener 2 do not rub.
First fastener 1 is L-shaped, thus facilitates the first fastener 1 and fastening of the second fastener 2.
When first anti-tripping 11 and second anti-tripping 21 is interlocked, the first fastener 1 and the second card
The maximum of fastener 2 angle between the two is 3.2 °.
Wherein, the second anti-tripping 21 top being positioned at the second fastener 2.
When elevator door receives external force collision, layer door hanging plate 4 gradually tilts, when the first fastener 1
It is 3.2 ° with the maximum of the second fastener 2 angle between the two, namely layer door base plate 3 and layer door
The angle maximum of link plate 4 can be 3.2 ° so that rail position upper gap is 4.3mm, between bottom
Gap is 5.9mm.It follows that elevator door link plate anti-drop device of the present utility model is in use,
Bigger external force collision can be born, 3.2 ° can be reached at the angle of inclination of layer door hanging plate 4 so that
Layer door hanging plate 4 can swing in a big way, and the first fastener 1 and the second fastener 2 are still
It is in buckling state, prevents layer door hanging plate 4 from coming off, thus prevent elevator door to come off, it is ensured that
Use safety.
Above is only preferred implementation of the present utility model, it is noted that general for this area
For logical technical staff, on the premise of creating design without departing from this utility model, it is also possible to if making
Dry deformation and improvement, these broadly fall into protection domain of the present utility model.
