The top of connecting rod is flexibly connected with lead screw, the bottom end of the first connecting rod and the second connecting rod respectively with the first transposition arm and
One end of second transposition arm is flexibly connected, and the other end of first transposition arm and the second transposition arm is movably connected with the base；Institute
Stating lead screw and being extended from intermediate position to two sides has forward screw thread and reverse thread, is flexibly connected at the forward screw thread
There is positive sliding block, reverse slide block, the top phase of the forward direction sliding block and first connecting rod are connected at the reverse thread
Connection, the reverse slide block are connected with the top of the second connecting rod.
The collapsible door frame includes crossbeam, and slideway is provided on the inside of the crossbeam, and the forward direction sliding block is slided with reversed
Block is run in slideway.
By adopting the above-described technical solution, a kind of bellow framed door structure disclosed by the utility model, when train arrives
It waits the motor control terminal starting collapsible door frame of motor control to fall in groove, train collapsible door frame rise, the peace after opening
Due to using foldable integral mode, all structures can easily be hidden to below ground effective solution full protection door gear
Platform since rain model is not fixed, caused by opening position be not fixed, set up the problem of fixed protective door hardly possible.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The some embodiments recorded in application, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model bellow framed door structure；
Fig. 2 is the structural schematic diagram of lead screw in the utility model.
Specific embodiment
To keep the technical solution of the utility model and advantage clearer, below with reference to attached in the utility model embodiment
Figure, clear and complete description is carried out to the technical scheme in the embodiment of the utility model:
A kind of bellow framed door structure as Figure 1-Figure 2, including collapsible door frame 200, the collapsible door frame 200
One end is connected with motor 1, and the motor 1 controls the rise and landing of collapsible door frame.Motor 1 receives the letter that enters the station of train
Collapsible door frame 200 is controlled after number to shrink and drop in groove, is controlled and is folded after motor 1 receives the exit signal of train
Formula door frame 200 rises.
The collapsible door frame 200 include two first connecting rods 5 arranged in a crossed manner and the second connecting rod 6, described first
Connecting rod 5 and the second connecting rod 6 are flexibly connected by connecting shaft 3, the bottom end point of the first connecting rod 5 and the second connecting rod 6
Be not flexibly connected with one end of the first transposition arm 7 and the second transposition arm 8, first transposition arm 7 and the second transposition arm 8 it is another
End is flexibly connected with pedestal 4.The first connecting rod 5 constitutes the first chain structure after connecting with the first transposition arm 7 by pin shaft
57, second connecting rod 6 constitutes the second chain structure 68 after connecting with the second transposition arm 8 by pin shaft.First connection
The top of bar 5 and the second connecting rod 6 is connected with lead screw 2.The lead screw 2, which is extended from intermediate position to two sides, to be had just
To screw thread 21 and reverse thread 22, it is connected with positive sliding block 211 at the forward screw thread 21, lives at the reverse thread 22
Dynamic to be connected with reverse slide block 221, the forward direction sliding block 211 is connected with the top of first connecting rod 5, the reverse slide block 221
It is connected with the top of the second connecting rod 6.The inside of crossbeam 20 is provided with slideway 9, the forward direction sliding block 211 and reverse slide block
221 run in slideway 9.
Under working condition: when motor operates, lead screw 2 being driven to rotate, due to being provided with forward screw thread 21 and reversed on lead screw 2
