Above -mentioned structure has easy maintenance, the fast effect of feedback.
Description
Technical field
This utility model is related to a kind of elevator mechanism, particularly door-opened elevator door knife.
Background technology
At present, the most complex structure of door-opened elevator door knife on the market, maintenance is inconvenient, and opens the door or close the door anti-
Feedback is not rapid, and when passing through or without croquet, door lock gib head can not timely be opened or close.
Utility model content
The purpose of this utility model is to provide a kind of easy to maintenance, feedback speed to solve above-mentioned the deficiencies in the prior art
Spend fast door-opened elevator door knife.
To achieve these goals, the door-opened elevator door knife designed by this utility model, including door knife base plate, is rotatably connected
Be arranged on a right blade that the left blade of knife base plate side is matched with left blade, the first drive link, the second drive link,
Follower link, the first kinematic link, the second kinematic link, power transmission shaft, locking board and door lock gib head it is characterised in that：A described left side
Four sides that blade and right blade are hinged and are formed with described follower link, the first drive link and the second drive link respectively
Shape structure, and the motion of described follower link, the first drive link and the second drive link can drive left blade and right blade
Mutually open or closed, described power transmission shaft is connected with left blade threaded upper ends, described left blade passes through the first kinematic link and door
Latch hook head is hinged, and described door lock gib head is provided with roller, and described right blade is fixed with pressing plate, described pressing plate and roller
It is slidably connected, described locking board is socketed with power transmission shaft, described door knife base plate is slidably connected by the second kinematic link and locking board.
Said structure has effect easy to maintenance, that feedback speed is fast.
The door-opened elevator door knife that this utility model obtains, it has the technical effect that by bar, the first drive link and the second drive
Dynamic connecting rod drives left blade and right blade mutually to open or close, and pressing plate is connected with roller-coaster, carries moveable lock hook gib head lifting
Or landing, and locking board serves spacing effect, have elevator through or when without croquet, door-opened elevator
The switch of door knife has the fast effect of feedback speed, and by the connection of above-mentioned simple components, each part passes through hinged, sliding type
Connect, structure is simple, easy to maintenance.
Brief description
Fig. 1 is the door-opened elevator door knife positive structure schematic of embodiment 1；
Fig. 2 is the door-opened elevator door knife backsight structural representation of embodiment 1.
In figure：Left blade 1, right blade 2, door knife base plate 3, the first drive link 4, follower link 5, the first kinematic link 6,
Second drive link 7, locking board 8, door lock gib head 9, the second kinematic link 10, power transmission shaft 11, pressing plate 2-1, roller 9-1.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
Embodiment 1：
As Fig. 1, shown in Fig. 2, the door-opened elevator door knife that the present embodiment provides, including door knife base plate 3, being rotatably connected is arranged on
Door knife base plate 3 side left blade 1 match with left blade 1 right blade 2, the first drive link 4, the second drive link 7,
Follower link 5, the first kinematic link 6, the second kinematic link 10, power transmission shaft 7, locking board 8 and door lock gib head 9, described left blade 1
Four sides being hinged and being formed with described follower link 5, the first drive link 4 and the second drive link 7 respectively with right blade 2
Shape structure, and the motion of described follower link 5, the first drive link 4 and the second drive link 7 can drive left blade 1 and the right side
Blade 2 mutually opens or closed, and described power transmission shaft 7 is connected with left blade 1 threaded upper ends, and described left blade 1 passes through first and is driven
Connecting rod 6 is hinged with door lock gib head 9, described door lock gib head 9 is provided with roller 9-1, described right blade 2 is fixed with pressing plate
2-1, described pressing plate 2-1 and roller 9-1 is slidably connected, and described locking board 8 and power transmission shaft 11 are socketed, and described door knife base plate 1 passes through
Second kinematic link 10 and locking board 8 are slidably connected.
During work, when by croquet, dynamic connecting rod 5, the first drive link 4 and the second drive link 7 drive elevator
Left blade 1 and right blade 2 mutually open, because the pressing plate 2-1 on right blade 2 and roller 9-1 is slidably connected, so driving roller
9-1 moves downward, and so that door lock gib head 9 is lifted based on the left side of above-mentioned front view, locking board 8 is to play position-limiting action, prevents door
Latch hook head 9 is deviate from.
