Abstract

The utility model relates to an inwardly-opening safety escape window which comprises an upper shackle, a lower shackle, a lock handle, a fixing seat, plate springs, a window frame and a window screen. One side of the window screen is movably connected to one side of the window frame while the other side of the same is fixedly connected with the fixing seat, the lock handle is fixed on the fixing seat, the plate springs are arranged between the lock handle and the fixing seat, the lock handle rotates by taking the center of the fixing seat as a rotating shaft, two ends of the rotating shaft are closed, the upper shackle is arranged at one end of the lock handle, and the lower shackle is arranged at the edge of the window frame. When the lock handle is pressed by an external force, the upper shackle and the lower shackle are separated, and the window screen is opened towards the indoor direction under action of the external force. During emergent situations, looking-for and rotating of a small handle positioned at a fixed position are not needed, convenience in operation is realized, needed time is short, saving of precious escape time is facilitated, and the inwardly-opening safety escape window can be widely used as a safety antitheft escape window.

Description

Inner-opening type safety escape window

Technical field

The utility model relates to a kind of window, specifically relates to a kind of inner-opening type safety escape window

Background technology

Along with the development of Building technology and human living standard's raising, the structure of window is also increasingly sophisticated to meet higher requirement.Modern window is generally made up of window frame, glass and movable part (hinge, handle, pulley etc.), window frame is responsible for supporting the main structure of forms, can be timber, metal, pottery or plastic material, transparent part is attached on window frame, can be paper, cloth, silk or glass material, movable part is mainly taking metal material as main, and the place of touching at staff also may be wrapped up with thermal insulation materials such as plastics.And require high building for antitheft, often adopt steel gauze, with the theftproof performance that ensures that it is best.

Existing security window is realized the folding of gauze and window frame by handle and snap close, not only inconvenient operation, and because handle is smaller, in case of emergency, when running into fire, be difficult for finding and touch handle, can delay so valuable escape time.

Therefore, do not affecting under the prerequisite of security protection, developing a kind of novel window of in case of emergency easily escaping and seem particularly necessary.

Utility model content

The above-mentioned shortcoming existing for prior art, the utility model provides a kind of inner-opening type safety escape window, the utility model in case of emergency, without finding and rotating that be in a fixed position, less handle, easy to operate, need the time short, be conducive to save valuable escape time, can be used as safe antitheft escape window and be widely used.

The utility model is achieved through the following technical solutions, a kind of inner-opening type safety escape window, comprise snap close, lower snap close, shank of the key, holder, leaf spring, window frame and screen window, described screen window be movably connected on described window frame while, the another side of described screen window is fixedly connected with described holder, described shank of the key is fixed on described holder, described leaf spring is arranged between described shank of the key and described holder, described shank of the key is taking the center of described holder as axis of rotation is rotated, the closed at both ends of axis of rotation, described upper snap close is arranged on one end of described shank of the key, described lower snap close is arranged on the edge of described window frame, when described in pressed by external force when shank of the key, described upper snap close and described lower snap close are separately, described screen window is opened to indoor direction under external force.

Preferably, the anglec of rotation of described shank of the key is 30～45 degree.

Preferably, the number of described leaf spring is 2.

Compared with prior art, the beneficial effects of the utility model are as follows: the utility model in case of emergency, without finding and rotating that be in a fixed position, less handle.Because shank of the key is longer, from window frame, edge extends to lower edge, be conducive to find and push shank of the key, and pushing when shank of the key, the separating of snap close and lower snap close in realization, and then open screen window, easy to operate, time is short, is conducive to save valuable escape time, can be used as safe antitheft escape window and is widely used in building field.

Brief description of the drawings

By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the local structure for amplifying schematic diagram at a position in Fig. 1.

In figure: 1 is that window frame, 2 is lower snap close, 3 is that shank of the key, 4 is that leaf spring, 5 is that screen window, 6 is that upper snap close, 7 is holder.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is elaborated.Following examples will contribute to those skilled in the art further to understand the utility model, but not limit in any form the utility model.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection domain of the present utility model.

A kind of inner-opening type safety escape window as depicted in figs. 1 and 2, comprise window frame 1, lower snap close 2, shank of the key 3, leaf spring 4, screen window 5, upper snap close 6 and holder 7, one side of screen window 5 by gemel connection in one side of window frame 1, the another side of screen window 5 is connected with holder 7 by screw, shank of the key 3 is fixed on holder 7, leaf spring 4 is arranged between shank of the key 3 and holder 7, the number of leaf spring 4 is 2 or 3 or more, the spacing of leaf spring 4 is 15cm, 2 effects are better, because when the number of leaf spring 4 is too much, push shank of the key 3 and need larger external force, be unfavorable for that the old,weak,sick and disabled in case of emergency uses, the material of leaf spring 4 can adopt spring steel, shank of the key 3 is taking the center of holder 7 as axis of rotation is rotated, the maximum anglec of rotation of shank of the key is 30,35,40 or 45 degree, the two ends of axis of rotation are sealed by screw, upper snap close 6 is arranged on one end of shank of the key 3, lower snap close 2 is arranged on the edge of window frame 1, in the time of pressed by external force shank of the key 3, upper snap close 6 and lower snap close 2 are separately.

When upper snap close 6 and lower snap close 2 separately after, by pulling screen window 5 to indoor direction, realize separating of window frame 1 and screen window 5, and then open escape window, therefore, can be used as the extensive use of safe antitheft escape window.

Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
