Description

A kind of locking device with a safety grid

Technical field

The utility model relates to a kind of anti-theft device, more specifically relates to a kind of band door safety grid locking device that window is installed that pastes.

Background technology

Safety grid is the most frequently used anti-theft device in ordinary residence building, generally is divided into the subsides window and installs and outwards give prominence to two kinds of installations.General resident is the convenience that gives the clothes an airing, or convenient for preventing the accident escape, usually opens Yishanmen on safety grid, adorns a lock; What also have is the antitheft dodge gate of not opening.But all there is defective in these two kinds of methods, and the lock on the former safety grid is easily prized, and causes safety grid non-anti-theft; Latter's inconvenience that not only gives the clothes an airing, in case breaking out of fire, door such as are shut at accident, oneself is containment also.

Having now carries out improved to safety grid, be called " emergent safety grid " as name, the patent No. is the utility model of CN1441144, it discloses a kind of emergent safety grid, it is characterized in that: dictyosome top is furnished with emergent lock, and emergent lock is installed in the wall of window top, and the dictyosome bottom fixes on the wall by hinges fixing, after emergent lock was opened, dictyosome can be to turning up to window.Its weak point is; Do not consider the needs (such as giving the clothes an airing etc.) of daily life, it is cumbersome that whole dictyosome is opened once, and emergent lock is installed in the window top, opens inconvenience; Also have name to be called " window safety grid ", the patent No. is the utility model of CN2375742, it discloses a kind of window safety grid, it is characterized in that: fan with the articulated escape of hinge on screen frame or the net lattice, the escape fan is made up of frame and welding fan lattice wherein, the lock that the escape fan can be locked in the fan frame is installed between the two, and the escape fan can turn up and become ladder.Its weak point is: do not consider the needs of daily airing equally, the escape fan is opened once cumbersome; Lock is directly installed between escape fan and the fan frame, is easily prized, and safety is relatively poor.

Summary of the invention

The utility model has proposed a kind of needs that can not only consider daily life at defective that exists in the above-mentioned background technology and deficiency, opens the safety grid window easily, and lock body is moved on the indoor wall, makes the robber not have the safety grid locking device that lock can be prized.

Implementation of the present utility model is: the inboard that safety grid is arranged on the glass sliding sash, open a safety grid dodge gate slightly littler than movable sliding window, described dodge gate and antitheft dictyosome are connected through the hinge, the lockhole that inserts for dead bolt is arranged on the dodge gate, described dead bolt insertion end has an inclined-plane, the other end is connected with locking bar, locking bar is provided with convex shoulder and has contact with projection, locking bar passes wall and enters lock box, be connected with having contact with spring respectively, have contact with and snap fit, promptly available padlock is locking bar and having contact with fixedly; Described lock box is buckled by lock box body, lock box cover, hinge, thrust and is formed.

Owing to adopted above scheme, make and the utlity model has such beneficial effect: the lock that will be directly installed on originally on the safety grid has moved on to indoor, and can open at any time easily, neither influence user's daily life, making the robber not have lock can prize, again can be in case of emergency, the escape of unblanking easily to window, and simple in structure, install easily, easy to use.There is curtain that lock box is covered at ordinary times, also do not influence indoor attractive in appearance.
