Description

Rear-mounted outward-opening window anti-falling device

the

technical field

The utility model belongs to a rear-mounted outer-opening window anti-dropping device.

Background technique

In building construction, the use of windows opening outwards is a common decoration method at present. After opening the outwards opening window does not occupy indoor space, and has a good sealing effect, which is loved by the public. However, the sash of outward opening windows is prone to fall off under strong winds and other weather conditions, especially in high-rise buildings, or in some coastal areas with large wind loads, the phenomenon of sash falling off occurs from time to time, which not only poses a threat to the lives of pedestrians downstairs It is very threatening, and it is very troublesome to replace and repair the window sash that falls off at the same time. The newly installed window sash and the overall structure are prone to structural deformation, displacement deviation and other consequences, which have a great impact on use. On the other hand, the country has clear prohibitive requirements for high-rise outward-opening windows.

Contents of the invention

Therefore, the purpose of this utility model is to design a rear-mounted outward-opening window anti-falling device, which can prevent the occurrence of window sash falling off, has the advantages of simple structure, fast construction speed, good fixing effect, convenient replacement and maintenance, long service life and easy use. The advantage of good effect.

For this reason, the utility model is mainly made up of window frame, window sash and glass, and this anti-falling device comprises, fixing device, and fixing device is made up of fixing plate, fixing screw, connecting hook and limit block, and fixing plate is positioned on it , The fixing screw at the lower end is vertically fixed in the gap on the side end of the window sash, the middle part of the fixing plate is provided with a connecting hook, and the front end of the connecting hook is provided with a limit block, and the connecting hook is inserted into the limit slot on the plug-in plate through the limit block ; Limiting device, the limiting device is composed of a plug-in board, fixing screws and a limit slot, the plug-in board is vertically fixed on the side end surface of the window frame opposite to the window sash through the fixing screws at the upper and lower ends of the side, A limit slot is arranged in the middle part of the plug board, and a connection hook is inserted in the limit slot. The width of the fixing plate is the same as the width of the gap on the side end surface of the window sash. An arc is formed between one end of the connecting hook and the limiting block. The connecting hooks are integrally formed by high-strength castings. One end of the limiting groove is provided with an opening. Above-mentioned structural design has reached the purpose of the utility model.

The utility model can prevent the window sash from falling off, and has the advantages of simple structure, fast construction speed, good fixing effect, convenient replacement and maintenance, long service life and good use effect.

Detailed ways

As shown in Figures 1 to 6, a rear-mounted outward-opening window anti-falling device mainly consists of a window frame 4, a window sash 5 and a glass 6. The anti-falling device includes,

Fixing device, the fixing device is composed of fixing plate 1, fixing screw 2, connecting hook 7 and limit block 8, the fixing plate is vertically fixed in the gap of the side end surface of the window sash through the fixing screws at the upper and lower ends of the fixing plate, and the middle part of the fixing plate A connection hook is provided, and a limit block is arranged at the front end of the connection hook, and the connection hook is inserted into the limit slot on the plug-in plate through the limit block. The limit block can fix the connecting hook in the limit groove. The connecting hook moves in the limit groove, and only takes effect when the window sash falls or the window sash is overturned, and does not affect the opening and closing of the window at ordinary times.

Limiting device, the limiting device is composed of plug-in plate 3, fixing screw and limit slot 9, the plug-in board is vertically fixed on the side end surface of the window frame opposite to the window sash through the fixing screws at the upper and lower ends of the side , the middle part of the plug board is provided with a limit slot, and a connecting hook is inserted in the limit slot.

The width of the fixing plate is the same as the width of the gap on the side end surface of the window sash. An arc is formed between one end of the connecting hook and the limiting block. The arc-shaped structural design increases the moving range and stress strength of the connecting hook. The connecting hooks are integrally formed by high-strength castings. An opening 10 is provided at one end of the limiting slot. The limit block on the connecting hook can be inserted into the limit groove through the opening.

When installing, first open the window sash, and drill a hole at the position where the anti-falling device needs to be installed on the window frame. On the side end of the window frame, insert the connecting hook into the fixing groove on the plug board, close the sash, and the installation is complete. The utility model can be assembled on site, and the replacement and maintenance are convenient.

In a word, the utility model can prevent the sash from falling off, and has the advantages of simple structure, fast construction speed, good fixing effect, convenient replacement and maintenance, long service life and good use effect.
