Abstract
A high magnetic lock of elevator door knife relates to the field of the elevator, which comprises an elevator door knife. The utility model is characterized in a magnet and a magnet block arranged on the device. The magnet is arranged on the bottom of the elevator door knife and the magnet block is arranged on the edge of the elevator door knife or the magnet is arranged on the edge of the elevator door knife and the magnet block is arranged on the bottom of the elevator door knife. The utility model has the advantages of simple structure, simple manufacturing process, low cost, convenience, energy-saving and long operating life of motor. During operating process of the elevator, the magnet and the magnet block are pulled together when the door is being locked. The elevator door knife can be pulled together by the magnet and the magnet block without turning on the door motor. Meanwhile, the door motor can be turned off and be cooled down during operating process of the elevator, which greatly improves the reliably of the elevator door motor and reduces the noise and the calorific value of the elevator door motor.
Description
Technical field
The utility model relates to elevator door cutter latching device, belongs to the elevator technology field.
Background technology
Present elevator door cutter latching device is generally nothing more than 2 kinds of ways are arranged: 1, the elevator door cutter after tightening, need door motor energising in addition certain moment make it to be in locking state, no matter its locking state door cutter opens or closes up, all need electrical power work, so door motor is switched on for a long time, make it produce very high temperature, influence the service life of door motor; 2, make elevator door cutter locking with an extension spring, but after fluffing or rupture as extension spring, cause elevator accident after making elevator door cutter system bump croquet.
The utility model content
The purpose of this utility model is will provide a kind of simple in structure, the Lift Door Lock Strong Magnetic Locking Apparatus that in-use performance is stable.
The purpose of this utility model is achieved in that Lift Door Lock Strong Magnetic Locking Apparatus, comprise the elevator door cutter, it is characterized in that being provided with magnet and magnet block, magnet is installed on the door cutter base plate of elevator, the magnet block is installed on the door cutter edge of a knife of elevator, or magnet is installed on the door cutter edge of a knife of elevator, and the magnet block is installed on the door cutter base plate of elevator.
Described magnet is the rare earth kicker magnet.
Described magnet is provided with the scalable mount pad, and the scalable mount pad is fastened on the door cutter base plate of elevator, and magnet is installed on the scalable mount pad.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and is easy to use, reduces the door motor work-hours, and energy savings prolongs motor service life.In the elevator use, magnet and the just in time adhesive of magnet block when the door cutter is locked, this moment door lock device do not need door motor energising acting and by magnet and magnet block mutually adhesive firmly live, therefore, when elevator moves, the door motor cooling of just can cutting off the power supply, this just guarantees the reliability of Automatic door of elevator machine widely, simultaneously, the door motor cooling that when elevator moves, can obtain having a rest, not only energy-conservation but also reduced noise of motor and the motor feels hot.
Description of drawings
Fig. 1 is the structural representation of not mode of operation of the present utility model;
Fig. 2 is the structural representation of mode of operation of the present utility model;
Among the figure: 1 magnet block, 2 magnet, 3 mount pads, 4 cutter base plates, 5 cutter edges of a knife.
The specific embodiment
One, the mount pad 3 of connection adjustable position on the door cutter base plate 4 of elevator, rare earth kicker magnet magnet 2 is fixed on the mount pad 3, on the door cutter edge of a knife 5 of elevator, install and fix magnet block 1, be installed in magnet 2 correspondences on the mount pad 3 and be installed in magnet block 1 on the cutter edge of a knife 5, guarantee when the locking of door cutter magnet and the just adhesive of magnet block.
Two, the mount pad 3 of connection adjustable position on the door cutter edge of a knife 5 of elevator, rare earth kicker magnet magnet 2 is fixed on the mount pad 3, on the door cutter base plate 4 of elevator, install and fix magnet block 1, be installed in magnet 2 correspondences on the mount pad 3 and be installed in magnet block 1 on the cutter base plate 4, guarantee when the locking of door cutter magnet and the just adhesive of magnet block.
