Abstract
The utility model provides a swing type lift door cutter comprising a micro motor, a microswitch seat, a motor seat and a fixing seat, the motor seat is installed on the upper portion of a lift car, and the fixing seat is installed on the lower portion of the lift car. The swing type lift door cutter further comprises a rack, a fulcrum shaft, a joint shaft, a swing rod and a door cutter, a microswitch touch board capable of touching and pressing a microswitch is arranged at one end of the rack, a push-pull rod is arranged at the other end of the rack, the push-pull rod is fixedly connected with the upper end of the swing rod through the joint shaft, the lower end of the swing rod is connected with the fixing seat through the fulcrum shaft, and the door cutter is fixed on the middle position of the swing rod. The door cutter mechanism is applicable for a lift manually opened and has the advantages of being smooth and steady in action, free of noise, low in failure rate, adjustable in travel, long in service life, convenient to maintain and the like.
Description
Technical field
The utility model relates to a kind of elevator door knife, relates in particular to a kind of oscillating type elevator door cutter.
Background technology
Along with the development of society, high buildings and large mansions stand in great numbers, and elevator brings great convenience to our live and work, and at present, what the elevator that opens Door by Hand used mostly is Electromagnetic door knife, and its noise is large, fault rate is high, stroke is non-adjustable.
The utility model content
The utility model purpose is to provide a kind of oscillating type elevator door cutter for the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of oscillating type elevator door cutter, comprise miniature motor, micro-switch seat and be installed in respectively the motor cabinet of car upper and the permanent seat of bottom, also comprise tooth bar, fulcrum shaft, joint shaft, fork and door cutter, described tooth bar one end is provided with the micro-switch striking plate that can press micro-switch, the described tooth bar other end is provided with pull bar, described pull bar is captiveed joint with the fork upper end by described joint shaft, described fork lower end is connected with permanent seat by described fulcrum shaft, and described door cutter is fixed on described fork medium position.
Preferably, described tooth bar is packed in the gear reduction box of miniature motor.
Preferably, described joint shaft passes the chute hole that described pull bar is provided with and captives joint with described fork.
Preferably, but the amplitude of fluctuation of the position control gate cutter by regulating described micro-switch.
The beneficial effects of the utility model: the elevator that this cutter mechanism is applicable to open Door by Hand has stable action, noiselessness, failure rate is low, stroke capable of regulating, long service life, the advantage such as easy to maintenance; Overcome that the Electromagnetic door knife noise is large, fault rate is high, stroke can not be adjusted, difficult in maintenance, shortcoming that service life is short.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is that the C of Fig. 1 is to view.
Among the figure: 1, miniature motor.2, fork, 3, motor cabinet, 4, the door cutter, 5, fulcrum shaft, 6, permanent seat, 7, car, 8, micro-switch, 9, the micro-switch seat, 10, the micro-switch striking plate, 11, tooth bar, 12, pull bar, 13, joint shaft.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of oscillating type elevator door cutter, comprise miniature motor 1, micro-switch seat 9 and be installed in respectively the motor cabinet 3 on car 7 tops and the permanent seat 6 of bottom, also comprise tooth bar 11, fulcrum shaft 5, joint shaft 13, fork 2 and door cutter 4, described tooth bar 11 1 ends are provided with the micro-switch striking plate 10 that can press micro-switch 8, and described micro-switch 8 is connected on the micro-switch seat 9; The described tooth bar other end is provided with pull bar 12, and described pull bar 12 is captiveed joint with fork 2 upper ends by described joint shaft 13, and described fork 2 lower ends are connected with permanent seat 6 by described fulcrum shaft 5, and described door cutter 4 is fixed on described fork 2 medium positions.Described tooth bar 11 is packed in the gear reduction box of miniature motor 1.Described joint shaft 13 passes the chute hole that described pull bar 12 is provided with captives joint with described fork 2.But the amplitude of fluctuation of the position control gate cutter 4 by regulating described micro-switch 8.
During use, the positive and negative running of control micro-motor 1 makes tooth bar 11 drive pull bars 12 and does straight reciprocating motion, and pull bar 12 promotes forks 2 and door cutter 4 around fulcrum shaft 5 rotary oscillations, cooperates with elevator door lock device and can finish unlocking action.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
