Abstract
The utility model relates to an elevator door knife with a self-locking function. The elevator door knife with the self-locking function comprises a door knife bottom plate and two door blades which are symmetrically arranged on the front face of the door knife bottom plate. Two connection rod components of the door knife which are arranged in parallel and vertical mode on the front face of the door knife bottom plate are movably connected with each other and the door blades are formed. The upper connection rod component of the door knife is in movable connection with a door knife limiting component which is arranged on the upper end portion of the door knife bottom plate. The door knife limiting component is connected with a sliding block component which is arranged on the back face of the door knife bottom plate. A door knife locking mechanism is arranged above the sliding block component and a door locking mechanism is arranged below the sliding block component. The elevator door knife with the self-locking function has the advantages of being simple in structure, convenient to install and dismantle, low in maintenance cost, high in safety coefficients and stable in operation.
Description
Technical field
The utility model relates to a kind of elevator assemblies, relates in particular to a kind of elevator door knife with auto-lock function.
Background technology
Elevator door knife is particularly important as the closing device of cage lifter Room door.Existing elevator door knife is because connection structure more complicated between door blade and the cutter base plate, removes and installs cumbersomely, and maintenance cost is also higher; And this elevator door knife fault rate is higher, occurs sometimes asynchrony phenomenon during shutter door, therefore, takes advantage of personal security to produce certain impact on the elevator visitor.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of folding flexible, running steadily, the elevator door knife with auto-lock function that safety factor is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elevator door knife with auto-lock function, comprise a cutter base plate and be arranged on positive upper two the symmetrical door blades of a cutter base plate, described door blade is by up and down two door cutter connecting rod assemblies flexible connections that are set up in parallel on door cutter base plate front, described to the doorstep cutter connecting rod assembly is flexibly connected with the door cutter limit assembly that is arranged on a cutter base plate upper-end part of driving, described door cutter limit assembly be arranged on a slide block assembly at the cutter base plate back side and be connected, described slide block assembly top is provided with a cutter catch gear, and the below is provided with door locking mechanism.
For folding that can the control gate cutter, further, described door cutter catch gear one end is connected with slide block assembly, the other end and be arranged on deep-slotted chip breaker flexible connection on the cutter base plate.
In order to improve elevator safety when the shutter door, more further, described door locking mechanism upper end is connected with slide block assembly, and the middle part is provided with oval groove and is arranged on center bearing pilot bearing flexible connection on the cutter base plate.
For slide block mechanism can be resetted, further, be provided with spring on the described slide block assembly.
Compared with prior art, usefulness of the present utility model is: this elevator door knife with auto-lock function is simple in structure, and installing/dismounting is more convenient, and maintenance cost is low, and safety factor is high, and running steadily.
