Description

General automatic Lock for crescent window

The utility model relates to a kind of sash lock, it is a kind of automatic Lock for crescent window that aluminium alloys, plastic-steel sliding window can be pinned automatically when closing window, be the general automatic Lock for crescent window that is applicable to that multiple model sliding sash is used, it is made up of crescent moon bolt, lock, two-way operating key, latch hook, touch panel etc.

At present I two the utility model automatic crescent lock patent ZL99236594.5 and the ZL99240074.8 that obtain have following shortcoming: the one, and need that sliding sash is installed with " triggering " that a fan of crescent lock seals and cut a breach, so that latch hook is freely passed through, therefore destroyed a seal structures, the 2nd, the touch panel complex structure, the 3rd, low to model sash lock versatilities such as 70,73,76,90, need make several latch hooks.

The automatic Lock for crescent window purpose of the utility model, exactly for overcome that above-mentioned shortcoming designs a kind of can general use on various windows and install and regulate all convenient and reliable automatic Lock for crescent window.

Being achieved as follows of the technical solution of the utility model:

(1), month bolt [1] is hingedly mounted on axis hole [12] on the flange [22] of lock [2], the axle bed [13], the axle [8] of crescent moon bolt [1] is offered two grooves [9], operating key [3] is hingedly mounted on the axle [14] of lock [2], the shoulder [20] of operating key [3] is pressed in by spring and blocks crescent moon bolt [1] in the groove [9], on the axle [10] of crescent moon bolt [1] opening [11] is set, 1. the prefix [19] of torsion spring [7] is stuck in wherein, and the other end of spring is lived by another axle bumper on the lock [2];

(2), on lock [2], the flange [22] that the screw hole front end protrudes the position is provided with axis hole [12] and the axle bed [13] that crescent moon bolt [1] is installed, the axle [8] of crescent moon bolt [1] is stuck on the axle bed [13] by check ring, go up the hinged operating key [3] and the spring [21] that can horizontally rotate an angle that be installed with at the axle [14] that lock [2] left side is provided with, for operating key [3] [4] horizontally rotates, offer a gap [16] in lock [2] left side, equally, for the shoulder [20] that makes operating key [3] blocks the groove [9] of crescent moon bolt [1] spool [8], also offer the gap [15] that can make operating key [3] shoulder [20] turnover in axis hole [12] left side of lock [2];

(3), folk prescription is hingedly mounted on the operating key [3] to operating key that is rotated down [4] and back-moving spring [17];

(4), be provided with one on the latch hook [5] and can promote the touch panel [6] that operating key [3] [4] rotates together, the work plane of touch panel [6] is designed to a screw inclined plane [18].

Owing to adopt such scheme, to various model sliding sashs, just can both use as long as move forward and backward the relative position that lock [2] regulates with latch hook [5], touch panel [6], its course of action is: it is that inclined-plane [18] by touch panel [6] promotes groove [9] realization that operating key [4] [3] rotates spool [8] of leaving crescent moon bolt [1] that the crescent moon bolt [1] that controlled key [3] blocks when closing window rotates into process latch hook in down in torsion spring [17] effect.When windowing, the operating key [4] that has moved on to touch panel [6] inclined-plane [18] below is blocked by inclined-plane [18] and bearing pin on operating key [3] is rotated down, and could slip over and open the window from touch panel [6].So this automatic crescent lock structure is light and handy, operate, install easy to adjust safe and reliable.
