Abstract
The invention discloses an elevator door knife with a self-locking function, which comprises a door knife bottom plate and two symmetrical door blades which are arranged at the front of the door knife bottom plate; the door blades are movably connected by two door knife connecting rod components which are arranged up and down in parallel at the front of the door knife bottom plate; the upper door knife connecting rod component is movably connected with a door knife limit component arranged at the upper end of the door knife bottom plate; the door knife limit component is connected with a sliding block component arranged at the back of the door knife bottom plate; a door knife locking mechanism is arranged above the sliding block component; and a door locking mechanism is positioned under the sliding block component. The elevator door knife with the self-locking function has the advantages of being simple in structure, more convenient to install and disassemble, low in maintenance cost, high in safety factor and stable in operation.
Description
Technical field
The present invention relates to a kind of elevator assemblies, relate in particular to a kind of elevator door cutter with auto-lock function.
Background technology
The elevator door cutter is particularly important as the closing device of cage lifter Room door.Existing elevator door cutter is because connection structure more complicated between door blade and the cutter base plate, removes and installs cumbersomely, and maintenance cost is also than higher; And this elevator door cutter fault rate asynchrony phenomenon occurs sometimes than higher during shutter door, therefore, takes advantage of personal security to produce certain influence to the elevator visitor.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of folding flexible, running steadily, the elevator door cutter that safety factor is high with auto-lock function.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: a kind of elevator door cutter with auto-lock function; Comprise a cutter base plate and be arranged on positive last two the symmetrical door blades of a cutter base plate; Said door blade is flexibly connected by two door cutter connecting rod assemblies that are set up in parallel on door cutter base plate front up and down, and said cutter connecting rod assembly to the doorstep flexibly connects with a door cutter limit assembly that is arranged on a position, cutter base plate upper end, said door cutter limit assembly be arranged on a slide block assembly at the cutter base plate back side and be connected; Said slide block assembly top is provided with a cutter catch gear, and the below is provided with the tight mechanism of door lock.
For folding that can the control gate cutter, further, said door cutter catch gear one end is connected with slide block assembly, the other end and be arranged on the deep-slotted chip breaker flexible connection on the cutter base plate.
In order to improve elevator safety property when the shutter door, more further, the tight mechanism of said door lock upper end is connected with slide block assembly, and the middle part is provided with oval groove and is arranged on the center bearing pilot bearing flexible connection on the cutter base plate.
For slide block mechanism can be resetted, further, said slide block assembly is provided with spring.
Compared with prior art, usefulness of the present invention is: this elevator door knife structure with auto-lock function is simple, and installing/dismounting is more convenient, and maintenance cost is low, and safety factor is high, and running steadily.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of elevator door cutter Facad structure scheme drawing with auto-lock function of the present invention;
Fig. 2 is a kind of elevator door knife back face structural representation with auto-lock function of the present invention.
Among the figure: 1, door cutter base plate; 2, door blade; 3, door cutter connecting rod assembly; 4, door cutter limit assembly; 5, the tight mechanism of door lock; 6, door cutter catch gear; 7, slide block assembly; 8, deep-slotted chip breaker; 9, center bearing pilot bearing; 10, oval groove.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
Fig. 1, a kind of elevator door cutter shown in Figure 2 with auto-lock function; Comprise a cutter base plate 1 and be arranged on a cutter base plate 1 positive last two symmetrical door blades 2; Said door blade 2 is by two door cutter connecting rod assemblies 3 flexible connections that are set up in parallel on door cutter base plate 1 front up and down; Said to the doorstep cutter connecting rod assembly 3 flexibly connects with the door cutter limit assembly 4 that is arranged on a position, cutter base plate 1 upper end, said door cutter limit assembly 4 be arranged on a slide block assembly 7 at cutter base plate 1 back side and be connected, said slide block assembly 7 is provided with spring; Said slide block assembly 7 tops are provided with a cutter catch gear 6, and the below is provided with the tight mechanism 5 of door lock; Said door cutter catch gear 6 one ends are connected with slide block assembly 7, and the other end flexibly connects with the deep-slotted chip breaker 8 that is arranged on the cutter base plate 1; The tight mechanism of said door lock 5 upper ends are connected with slide block assembly 7, and the middle part is provided with oval groove 10 and flexibly connects with the center bearing pilot bearing 9 that is arranged on the cutter base plate 1.
Its concrete mode of operation is following: when opening the door, the traction sheave that is arranged on the elevator motor rotates, and drives croquet upwards; And then between the access door blade 2; Door blade 2 is strutted, and carries out spacingly through door cutter limit assembly 4, and door cutter limit assembly 4 drives slide block assemblies 7 and moves; And then slide block assembly 7 driving gate catch gears 5 and 6 runnings of door cutter catch gear, the realization elevator opens the door and locks; When closing, croquet is downward, and the spring driving sliding block on the slide block assembly 7 resets, and then door blade 2 closures, realizes closing the door and locking.
This elevator door knife structure with auto-lock function is simple, and installing/dismounting is more convenient, and maintenance cost is low, and safety factor is high, and running steadily.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
