Description

A kind of door lock of elevator

Technical field

The utility model relates to elevators field, especially a kind of door lock of elevator.

Background technique

Door lock of elevator is the important component of elevator safety fortune, when the eligible elevator ability rise and fall of door lock, at present Most of design comparisons are complicated, and there are security risks.Existing door lock of elevator generally comprises lock crook plate, latch hook, mounting plate, moves Idler wheel determines idler wheel and bearing block etc., is a kind of elevator door lock device, layer door door if China Patent Publication No. is 203682842 Lock hook locking component includes lock crook plate 4 and latch hook mounting plate 21, and 4 front of lock crook plate is equipped with latch hook A5,4 rear portion of lock crook plate Be rotatably mounted on the side of latch hook mounting plate 21, the vertical plane of the vertical plane of the lock crook plate 4 and latch hook mounting plate 21 there are Spacing is equipped with mounting plate A7 at the top of lock crook plate 4, is equipped with mounting plate B22 below the mounting plate A7, the mounting plate B22 exists 21 front-end surface of latch hook mounting plate is equipped with limiting device 13, mounting plate B22 between the mounting plate A7 and mounting plate B22 Bottom is installed with screw 9, and the screw 9 passes through limiting device 13 through mounting plate B22 and sequentially passes through door through mounting plate A7 Lock plastics 14, spring base 8, spring 12, spring base 8 and nut, mounting plate A7 front bottom end are equipped with contact mounting base C6, institute Contact mounting base C6 front bottom end is stated equipped with movable contact A2, the lower section mounting plate B22 is equipped with the gear screw 10 to limit, lock 4 rear portion of hook plate is mounted on latch hook mounting plate 21 by bearing block 24, and 4 rear portion of lock crook plate extends outward mounting plate upwards C23, bearing block 24 are equipped with limit lantern ring 25 outward, are mounted on pulley on the mounting plate C23 and limit lantern ring 25, Pulley is the use in order to cooperate a knife.It is provided by bearing block in lock crook plate, installation for determining the bearing that idler wheel is pivotally connected, It needs for bearing block to be fixed on lock crook plate, then needs for bearing to be fixed in bearing block, the door latch structure of this kind of structure is multiple It is miscellaneous, and assembly technology trouble.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of door lock of elevator, and structure is simple, and assembly technology is simple.

In order to solve the above technical problems, the technical solution of the utility model is: a kind of door lock of elevator, including lock crook plate, lock Hook and lock hook seat, the lock crook plate, latch hook and lock hook seat are integrated, and the lock hook seat is integrally drawn on lock crook plate Type, the lock hook seat include ring set, and ring set is located at the side of lock crook plate, and the side of ring set connect with lock crook plate and connects with lock crook plate The side connect, which is equipped with, is installed to the indentation mouth in ring set for bearing, and the other side of ring set extends inwardly to form retaining ring.This is practical new The lock hook seat of type is equivalent to bearing block, and lock hook seat and lock crook plate are integrally formed, and components are less, and overall structure is simpler；In addition, Due to saving bearing block, without being installed to bearing block, so also simpler in technique.

As an improvement, the top of the lock crook plate is equipped with the reset spring mounting base rearwardly bent.

Dynamic idler wheel mounting base is equipped with as an improvement, upwardly extending at the top of the lock crook plate.

As an improvement, the side of the bearing offsets with the retaining ring, the other side of bearing and the riveting on ring set inner wall Point offsets.

Brought beneficial effect is the utility model compared with prior art:

The lock hook seat of the utility model is equivalent to bearing block, and lock hook seat and lock crook plate are integrally formed, and components are less, whole Structure is simpler；In addition, due to saving bearing block, without being installed to bearing block, so also simpler in technique.
