Abstract

The utility model relates to an elevator car door lock comprising a car door locking hook arranged on a car door, a car door locking shaft and a car door locking hook, wherein the car door locking hook can hook the car door lock shaft for locking the elevator car door; the car door lock hook is provided with a rotating shaft and a roller; and the roller can drive the car door locking hook to rotate and separate from the car door locking shaft by being matched with a final limit cam on the elevator layer door. The elevator car door lock has simple structure, locks the car door by the car door locking hook after the door machine closes the door in place, and can effectively prevent a person in the car to open the car door at the non-leveling layer position of the elevator or in the process of running upward and downward or due to other misoperation for interfering door opening, thus avoiding the potential safety hazard that the person in the car falls into the hoistway due to scrabbling of the door when in non-leveling position.

Description

Elevator cage door lock

Technical field

The utility model relates to the lift facility technical field, further relates to a kind of lockset that is applied to the elevator horizontal slip gate of vertical lift.

Background technology

The horizontal slip gate of general vertical lift elevator is usually all by its operation of gate motor-driven.Its overwhelming majority does not possess locking device, and only depend on unlatching that controller controls motor action and stop to locate gate: other has part to rely on the door motor with holding torque to guarantee the closed condition of gate.Yet when making the door motor outage in case elevator breaks down, this class horizontal slip gate can be opened easily, exists greatly potential safety hazard.

Complicated in mechanical structure in the existing in addition gate lock, the cost of manufacture height, mounting means is loaded down with trivial details, even causes the gate latch hook to open, and makes rate of breakdown higher, and some gate lock adopts electromagnetic principle, and only the gate lock just can be opened when elevator has electricity.The gate that has lock only just can be opened gate lock machine tool complex structure, the situation that involves great expense when gate or layer door are asynchronous.

The utility model content

Technical problem to be solved in the utility model is, overcomes the gate lock machine tool complex structure that exists in the prior art, involve great expense problem, a kind of simple in structure, easy manufacturing easy for installation, safe and reliable elevator cage door lock.

In order to address the above problem the technical solution of the utility model is such:

Elevator cage door lock, comprise the gate latch hook, the gate lock shaft that are arranged on the gate, the gate latch hook can hook the gate lock shaft in order to pin elevator cage door, and the gate latch hook has a rotating shaft and a roller, and roller can match and drive the gate latch hook and rotate and break away from the gate lock shaft with the bow that hits on the elevator door.

Described gate lock shaft is arranged in the long slot bore, and the gate lock shaft can slide in long slot bore.

The hook end front portion of described gate latch hook is sharp-pointed triangle.

Described gate latch hook is connected with an interlocking switch contact socket, and described gate lock shaft is connected with an interlocking switch contact plug, and interlocking switch contact socket and interlocking switch contact plug can touch conducting mutually.

The relative projection of described roller with plane, gate latch hook place.

Beneficial effect, gate lock construction of the present utility model is simple, after putting in place, gate is pinned at door office door by the gate latch hook, can effectively prevent by personnel in the car at the non-level position of elevator or up and down in the running or other disturb enabling signal maloperations and gate is opened, thereby the personnel in the car of stopping take off the fall potential safety hazard of hoistway of door when luxuriant and rich with fragrance level position.The utility model elevator cage door lock functional performance is safe and reliable, and manufacturing process is simple, and maintenance and inspection are convenient, and cost is low, and in the Elevator landing zone, no matter whether elevator has electricity, and the passenger can both open gate in car, but all kinds of elevator door-motors of extensive use.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1-Fig. 3

In the present embodiment, elevator cage door lock comprises a gate latch hook pedestal 1, latch hook guide strip 2, gate lock roller 3, axle sleeve welding base plate 4, gate latch hook 7, gate lock shaft bottom deck assembly 8 and interlocking switch contact plug 9, interlocking switch contact socket 10; Interlocking switch contact plug 9 can up-down adjustment, guarantees circuit clear.Gate lock shaft bottom deck assembly 8 is installed on the door hanging plate.Hitting bow 11 is fixed on the elevator door device of each layer.

Gate latch hook pedestal 1 is fixed on the gate by a flange nut 5 and an axle sleeve welding base plate 4, and flange nut 5 also connects a guide rail 6 simultaneously, makes elevator cage door move in guide rail 6 sliding scales.

Gate latch hook 7 can rotate, the root of gate latch hook 7 has a gate lock shaft 71, gate latch hook 7 rotates within the specific limits around gate lock shaft 71, can rotate in restricted portion in order to make gate latch hook 7, also is provided with a latch hook guide strip 2 on the gate latch hook pedestal 1.

Gate lock shaft 71 is arranged in the long slot bore 72, and gate lock shaft 71 can slide in long slot bore 72.

Also connect a gate lock roller 3 on the gate latch hook 7, the relative projection of gate lock roller 3 with plane, gate latch hook 7 place.Hitting bow and can touch gate lock roller 3 on the elevator door rotated thereby drive gate latch hook 7.
