Abstract

The utility model relates to an automatic window closing wind hook. The utility model is technically characterized in that a movable connecting supporting seat 5 and a wind hook rod 1 directly pass through a base seat 5 with a shrapnel 2; a saw tooth and a square groove are arranged on the wind hook rod 1. The base seat 5 which is divided into two layers is fastened by a fastening screw. The upper part of the base seat 5 is provided with a manual rod 3, the lower part is provided with a movable frame 4, and the side edge is provided with a stop rod. The utility model has the advantages of simple structure, high durability, cheap price, convenient installation, etc., automatically closes doors and windows when the utility model encounters wind energy with more than 3 stages, and is used for fixing the doors and the windows at optional positions.

Description

Automatic window closing hook

The utility model relates to the door and window immobilising device, especially a kind of automatic pass sash fastener.

Be the fixing device of window of fixing drag hook or other form at traditional door and window; great majority are fixed, and it can not be fixed according to people's enable possition, can not be according to the variation of weather; adjust the size of the unlatching of window, protect indoor property not to be subjected to the damage of strong wind or heavy rain.

The purpose of this utility model is a kind of window catch that can close window automatically of design, just can realize window is closed automatically as long as this window catch runs into the wind that has more than 3 grades.

The purpose of this utility model is to realize like this, form by window catch bar base and bearing etc., it is characterized in that: the bearing of flexible connection and window catch directly pass through in having the base of shell fragment, the window catch bar is provided with sawtooth and square groove, base is divided into two-layerly to be fixed by trip bolt, on base, be provided with hand lever 3, the bottom is provided with travel(l)ing rest, side is equipped with arresting lever, bearing be shaped as triangle, which is provided with an elongated slot, two of groove has pit on one side, the lower floor center that travel(l)ing rest is connected with base have can and the groove that matches of window catch bar, have the space and the corresponding groove of fixation spring tab of shell fragment under the groove, the corresponding shell fragment in the upper strata of base place has the through hole of an installation hand lever.

The utility model has simple in structure compared to existing technology, and overall compact is reasonable, and is cheap, and the unlatching activity freely, and is easy for installation, and window both can have been realized standard-sized sheet, half-open or little half-open position, runs into to scrape wind energy and close automatically.

Accompanying drawing is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model is further described.

Referring to accompanying drawing, two holes on the bearing 6 directly are loaded on the bottom of window with screw, bearing 6 and window catch bar 1 usefulness screw are adopted flexible connection, window catch bar 1 directly inserts in the base 5, base 5 is formed by stacking by two-layer, the employing trip bolt is fixed, because the lower floor of base 5 is provided with and window catch bar 1 corresponding groove, have the space of position of shell fragment 2 movement locus sizes and the groove of fixation spring tab 2 in the bottom of groove, in the direct insertion groove of shell fragment 2, the arresting lever 7 of the upper strata of base 5 and shell fragment 2 is equipped with travel(l)ing rest 4 in the bottom of base 5, and travel(l)ing rest 4 is fixed on the window frame.

Its course of work is: when wind acts on the window, act directly on by the bearing on the window 6 on the flexible connection point of window catch bar 1, when wind-force surpasses the frictional force of shell fragment 2 and window catch bar 1 sawtooth, bearing 6 leans near more with base 5 more, shell fragment 2 is when the sawtooth of window catch bar 1 can not slide, this moment, window was all shut, because the effect of the sawtooth of shell fragment 2 and window catch bar 1, window catch bar 1 can't slide.When needs are opened window, with the moving hand lever 3 of hand, the sawtooth of the hand lever 3 compressing shell fragments 2 poor shanks 1 that blow in.The window catch bar just slidably.When window does not need to close automatically, arresting lever 7 can be put into the square groove of window catch bar 1, at this moment, all can't slide in window catch bar 1 front and back in base 5, directly window is fixed on a certain position.

Because the window closing movement is arc trajectory, therefore, base 5 connect travel(l)ing rest 4 with screw, the window motion directly drives 1 motion of window catch bar, so base 5 is answered corresponding movement in a curve thereupon.
