Adjustable automatic door lock device

Abstract

An adjustable automatic gate lock device includes the adjustable automatic gate lock installed in the door slide board. The adjustable automatic gate lock with the adjustable contactor matched to the contact bed includes the motherboard installed in the gate slide board which is riveted to the motherboard axis with the rotary lock motherboard which can clip the adjustable board by the controlling device composed by the bolt, the gasket and the heavy punch. The gate ball motherboard riveted with the gate ball axis, is fixed in the adjustable board by the flat head bolt. The rotary gate ball is installed in the gate ball axis. The gate lock motherboard is connected with the lock head which is riveted the gate axis. It can reach: the first: the distance between the gate ball of the lock and the litter compartment floor ridge matches to the standard; the second: the ball matches to the gate tool perfectly; the third: it can match to different type of the tools.

Description

technical field [0001] The invention relates to an adjustable automatic door lock device for elevator hall doors. Background technique [0002] The door lock used by the elevator hall door is closely matched with the door knife installed on the elevator car door through two rotating door balls installed on the door lock device. The movement of the door knife drives the door lock to move synchronously to reach the car door and the hall. The purpose of the door switch. The horizontal distance between the gate ball of the door lock and the sill of the car must meet the national (international) standard. Whether the cooperation between gate ball and door knife is ideal will directly affect the operation effect of hall door and car door and the frequency of failure. Whether the design of the door lock is reasonable or not will directly affect the installation and commissioning and work efficiency. [0003] As a manufacturer of the door opening system used in elevators, it invo...

AI Technical Summary

Problems solved by technology

The deficiencies of its existence are: (1) The door ball and the door knife can be closely matched in theory, but in the production process of the door lock and the door knife, it is impossible to achieve the same relative position of the door ball, and the opening and closing of the door knife The size is exactly the same, due to the existence of uncertain factors, there will be: when the door knife of the car door is closed, the door ball of the door lock is clamped too tightly, the door knife is easily damaged due to a large force, or the door knife of the car door is closed when it is closed. If the ball fit is too loose, there will be gaps, and vibration will be generated when the door knife drives the door lock to move, the hall door and car door will not run smoothly, and the use effect will be poor, and the door lock will easily be damaged due to long-term vibration, resulting in failure

(2) Because the door lock can only move horizontally, if the horizontal distance between the gate ball of the door lock and the sill of the car does not meet the standard during installation and debugging, the hall door or car must be moved to meet the standard, and the installation and debugging are not satisfactory. Convenience, low work efficiency

[0006] 3. The applicability of the door locks described in Scheme 1 and Scheme 2 can only be aimed at the technology of the manufacturing enterprise itself. In the vast elevator transformation and maintenance market, it is only applicable to its own door machine and door lock. Therefore, the limitation Strong, not widely applicable
