Abstract

The utility model discloses a self-controlled protective window which relates to the improvement of the structures of civil protective windows. The utility model comprises a window frame and a folding window sash, wherein, the bottom beams of the folding window sash are respectively connected with ropes on guide pulleys on both sides of the window frame, and the ropes are connected with rocking handles by a gear transmission mechanism. Switch locks are arranged on the bottom beams. The utility model has the advantages of reasonable and compact structure, flexible operation, etc.

Description

Automatic controlled protective window

The utility model relates to the improvement of civilian protective window structure.

Present horizontal slide fastener folding window or roller shutter window mainly are to open or shut window by push-and-pull, but because structure is unreasonable, and forms move and are difficult to keep translation, and to be vulnerable to therefore that its track hinders, push-and-pull is got up time-consuming, require great effort.

The purpose of this utility model just provides a kind of automatic controlled protective window of rational in infrastructure, processing ease.

The purpose of this utility model is achieved in that the utility model comprises window frame, folding sash, the folding window fan pass is crossed to put the beams in place and is fixed on the window frame, its structural feature is that the bottom girder of folding sash links to each other with rope on two side guide wheels of window frame respectively, and rope links to each other with rocking handle respectively by gear drive; Bottom girder is provided with switch lock.

Major advantage of the present utility model:

1, rational in infrastructure, compact:

Because in the window frame that the motion of control folding window of the present utility model is provided with, its member such as rope, drive gear mechanism is simple and few, so compact overall structure, provide convenience between user's two-layer window, this device being set, not only provide reliable and secure assurance, and be beneficial to beautifying of environment to the user;

2, flexible operation:

The utility model is that two side guide wheels of window frame are provided with rope, has guaranteed the bottom girder translation, has promptly guaranteed the even running of sash, for the operator provides convenience.

Fig. 2 is a sash structures schematic diagram of the present utility model;

Fig. 3 is the schematic diagram of control elevating mechanism of the present utility model;

Fig. 4 is a gear drive schematic diagram of the present utility model;

Fig. 5 is the front view of lock body of the present utility model and relevant portion structure.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:

The utility model comprises window frame 7, folding sash 5, and folding sash 56 is fixed on the window frame 7 by putting the beams in place, and the bottom girder 4 of folding sash 5 links to each other with the rope on two side guide wheels 10 of window frame 78 respectively, and rope 8 links to each other with rocking handle 2 by gear drive 11; Bottom girder 4 is provided with switch lock 3.

For making folding sash 5 operations more steady, can be provided with buffer spring 9 by rope 8.

Can between rocking handle 2 and gear drive 11, be provided with clutch 13.Clutch 13 comprises interior cover 14, the overcoat 12 on the rocking handle 2, and in the groove 16 of cover 14, the locking plate 15 in the groove 16 was fixed on the drive gear mechanism 11 in the two ends of the torsion spring 17 between interior cover 14, the overcoat 12 were provided with.

The conventional article that switch lock 3 of the present utility model is easily purchased for market; The lock hook 18 that can switch lock 3 be provided with rotatable 90 ° of angles with lock hook 18 or tangle or leave window frame 7, reaches the purpose of switch sash 5.

Narration use of the present utility model below:

At first window frame 7 is fixed on the building by set bolt 1.When desiring to draw back (or closing) sash 5, rotation crank 2 is just changeing (or counter-rotating), and interior cover 14 drives torsion springs 17, locking plate 15, travelling gear machinery 11 and rotates, and rope 8 (or the downwards) motion that thereupon makes progress drives upwards (or downwards) motion of sash 5.When sash 5 falls because of deadweight, the locking plate 15 of rope 8 driven gear transmission mechanisms 11 rotates, locking plate 15 forces the torsion spring 17 in the groove 16 outside, and in promptly torsion spring 17 is stuck between cover 14, the overcoat 12, locking plate 15 no longer rotates, rope is 8 motionless, sash 5 is also located thereupon.
