Description

A kind of elevator door knife

Technical field

The utility model relates to a kind of elevator accessory, particularly relates to a kind of elevator door knife being applied in responsible switch elevator cage door in elevator.

Background technology

The horizontal slip gate of general vertical lift elevator, all drives it to run by gate motor usually.Its overwhelming majority does not possess latching device, and the unlatching only controlling motor action by controller locates gate with stopping, separately having part to rely on the door motor with hold torque to ensure the closed condition of gate.But break down once elevator and make door motor power-off, this kind of horizontal slip gate then can be opened easily, there is greatly potential safety hazard.

Complicated in mechanical structure in existing elevator door knife in addition, cost of manufacture is high, and mounting means is loaded down with trivial details, even causes gate latch hook to open, makes rate of breakdown higher, and some car door lock adopts electromagnetic principle, and only when elevator has electricity, car door lock just can be opened.Some car door lock, only gate or layer door asynchronous time just can open, car door lock complicated in mechanical structure, the situation involved great expense.

Utility model content

Because the above-mentioned defect of prior art, technical problem to be solved in the utility model overcomes the door cutter complicated in mechanical structure existed in prior art, involve great expense problem, provide a kind of structure simple, easy manufacture easy for installation, safe and reliable elevator door knife.

For achieving the above object, the utility model provides a kind of elevator door knife, comprise first tool arm and second tool arm, first described tool arm and second tool arm lower end respectively by the first bearing pin and the second bearing pin and swinging block two ends hinged and form the first hinge and the second hinge respectively, described swinging block centre portion and the 3rd hinge form the 3rd hinge, and the 3rd described hinges fixing fixes on a cutter base plate lower end; It is characterized in that:

First described tool arm and second tool arm upper end are respectively by the 4th bearing pin and the 5th bearing pin and door cutter centering block lower end hinged formation the 4th hinge and the 5th hinge;

Described door cutter centering block interlude is threaded connection one end of fixing fork;

Described door cutter centering block lower end is also formed with the 6th bearing pin one end and hingedly obtains the 6th hinge, the 6th described bearing pin other end is fixed on a cutter base plate upper end, and be provided with the first shaped groove this connecting portion is on the upper side, what fork stretched out bearing partially passes through the first shaped groove;

Described outside race coordinates with the curved surface that coordinates of door cutter, forms the 7th hinge in the middle of described door cutter by the 8th bearing pin and door cutter base plate hinged;

Described door cutter comprises hook end and reset terminal, and described reset terminal and stretching out between block of door cutter base plate are connected with a cutter retracing spring;

Described door cutter centering block top and clamping block are connected and fixed; When door cutter cuts out, door cutter retracing spring is extended state.

Further, the described fork other end is fixed with bearing, and fork stretches out bearing one segment distance.

The beneficial effects of the utility model are: elevator door knife structure of the present utility model is simple, by door cutter latch hook, gate is pinned after door machine door-closing in-place, can effectively prevent by personnel in car at the non-level position of elevator or up and down in operational process or other interference enabling signal maloperations and gate is opened, thus the personnel in car that stop take off door falls the potential safety hazard of hoistway when luxuriant and rich with fragrance level position.The utility model elevator door knife in-use performance is safe and reliable, and manufacturing process is simple, and maintenance and inspection are convenient, and cost is low, and in Elevator landing region, no matter whether elevator has electricity, and passenger can open gate in car, can all kinds of elevator door-motor of widespread use.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

See Fig. 1 to Fig. 9, a kind of elevator door knife, comprise first tool arm 1 and second tool arm 2, described first tool arm 1 and second tool arm 2 lower end are hinged and form the first hinge and the second hinge respectively with swinging block 5 two ends respectively by the first bearing pin 3 and the second bearing pin 4, described swinging block 5 centre portion and the 3rd bearing pin 6 hinged formation the 3rd hinge, the 3rd described hinge 6 is fixed on cutter base plate 16 lower end;

Described first tool arm 1 and second tool arm 2 upper end are respectively by the 4th bearing pin 8 and the 5th bearing pin 7 and the hinged formation in door cutter centering block 9 lower end the 4th hinge and the 5th hinge;

Described door cutter centering block 9 interlude is threaded connection one end of fixing fork 10, described fork 10 other end is fixed with bearing 14, and fork 14 has stretched out bearing one segment distance;

Described door cutter centering block 9 lower end is also formed with the 6th bearing pin 15 one end and hingedly obtains the 6th hinge, the 6th described bearing pin 15 other end is fixed on cutter base plate 16 upper end, and be provided with the first shaped groove 1601 this connecting portion is on the upper side, what fork 14 stretched out bearing partially passes through in the first shaped groove 1601;

Described door cutter centering block 9 top and clamping block 12 are connected and fixed;

Described bearing 14 outer ring coordinates with the curved surface 1101 that coordinates of door cutter 11, by the 8th bearing pin 13 and door cutter base plate 16 hinged formation the 7th hinge in the middle of described door cutter 11;

Described door cutter 11 comprises hook end 1102 and reset terminal 1103, and described reset terminal 1103 and stretching out between block 1602 of door cutter base plate 16 are connected with a cutter retracing spring 17, and when door cutter cuts out, door cutter retracing spring 17 is extended state;

Elevator cage door lock comprises buckle 18, and described buckle 18 both sides are provided with buckle adapter plate 1801, and described buckle adapter plate 1801 is provided with buckle fixed orifice 1802, and side is provided with sliding pin adapter plate 1804, this side is also provided with cooperation reset hole;

Front panel assembly 20 is fixed with mounting portion 25, described side, mounting portion 25 is provided with the first connecting panel 2501, opposite side is provided with the second connecting panel 2502, the first described connecting panel 2501 and the second connecting panel 2502 are provided with the connecting through hole corresponding with buckle fixed orifice 1802, the second connecting panel 2501 is also provided with reset hole;

Described buckle adapter plate 1801 is through the mounting groove 1902 of substrate 19, make buckle fixed orifice 1802 and connecting through hole just to and reset hole with coordinate reset hole just right, mounting portion 25 and buckle adapter plate 1801 are assembled together through connecting through hole and buckle fixed orifice 1802 by connecting pin 22, and described substrate 19 is fixed on elevator shelf;
