Description

The door window antitheft switch

Technical field

The utility model relates to Switch for door and window, especially a kind of anti-theft switch that is used for push-pull door and window.

Background technology

At present, push-pull door and window generally adopts the rotary shaft switch, the rotary shaft switch is very insurance on laterally closing the doors and windows, but when installing owing to push-pull door and window, good and sound whole window frame on wall at first, then in the slide rail on the sash upper end insertion window frame, again high sash lower end, window frame limit under being higher than being pushed the slide rail intermediate vertical falls, pulley drops on the window frame glidepath below the sash, and two still have the space above the sash and below the sash, even like this when the rotary shaft switch closure, also can be by making progress simultaneously, lift sash downwards, from vertically going up sash is opened, and made the rotary shaft switch lose the effect of fixedly closing sash, can not be antitheft.

The utility model content

The purpose of this utility model is exactly in order to overcome existing slide door or window switch and to close, the defective that sash is easy to open, and a kind of door window antitheft switch is provided.

The technical scheme that its technical problem that solves the utility model adopts is:

The door window antitheft switch, comprise base and the holder that matches, it is characterized in that: the base front end stretches out a pair of blocking arm and constitutes an opening, each blocking arm is provided with a through hole, also be provided with two hinged opening on the base and open pincers, two are opened pincers middle parts and are provided with spring and connect, and each is opened and opens the fixedly connected card wedge of pincers front end, each card wedge respectively with blocking arm on through hole be connected; The holder front end stretches out plug, and plug is provided with tenon, and tenon becomes buckle to be connected with a pair of card wedge shape.

Each is opened the handle and the jaw that open pincers and is positioned at same side, and is opposite with general pliers mode of occupation, when the handle of general pliers struts, jaw struts, and handle of the present utility model and jaw are positioned at same side, when handle is mediated, jaw is opened, and so more helps people's use.

On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:

Each opens the pincers front end and is respectively equipped with a chute, a fixedly connected pin on each card wedge, and pin and chute are slidingly matched.Like this, open pincers when hinged center drive card wedge is opened when opening, pin is the slidable adjustment position in chute, makes rectilinear motion in the through hole of card wedge on blocking arm, prevents that the card wedge is stuck in through hole.

Spring is arranged on two and opens the pincers rear end, and the spring force direction is outside, makes to open to open pincers and be kept closed, and spring opens the pincers middle part and adjusts to the rear end by opening, and can prevent the interference of spring and other object.

The cross section of blocking arm is " L " type, through hole is located on the vertical part in " L " cross section, even make to open and open pincers under the effect of spring, not closed yet, and remaining parallel open, and when holder and two claws formed buckle and are connected, " L " type blocking arm on the base kept off the both sides at holder front end plug, limited the motion of holder, just limited the motion of slide door or window above-below direction at longitudinal direction (above-below direction).

Holder front end plug is provided with a pair of groove that matches with two card wedges; Two card wedges can directly insert in the groove, and this scale wedge is connected more firm with the buckle that groove forms.

The beneficial effects of the utility model are after sash is closed, and can not open sash from the outside by moving up and down window; It is more firm that sash is closed, and can prevent that other people from cracking a crib; Overall structure is simple, and is easy to use flexible.

Below in conjunction with drawings and Examples the utility model is further specified.
