Description

Window stopper

technical field

The utility model relates to a position-limiting device for casement windows and hanging windows, in particular to a window-opening position-limiting brace.

Background technique

When the window is opened, it needs to be fixed at a certain opening angle to achieve the effect of lighting and ventilation. The existing limit brace includes a cantilever, a bottom groove, and a limit block installed in the bottom groove. There are locking screws on the top, the limit block is hinged with the end of the cantilever, and the other end of the cantilever is hinged with a support piece, which is fixed on the window. When the window rotates, the support piece rotates accordingly, and the cantilever drives the limit block in the bottom groove Slide inside, and fix the limit block by turning the locking screw to achieve the purpose of fixing the window. This device mainly prevents the movement of the cantilever through the friction force between the locking screw and the bottom groove, thereby fixing the window. When the wind force is too strong and the thrust of the cantilever is greater than the friction force, it will still drive the limit block to slide, and at the same time produce a lot of friction. The large inertia makes the window close suddenly, which is easy to break the glass and cause losses; in addition, it often takes a lot of force to tighten the locking screws when fixing the window, which is inconvenient to use.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a window-opening limit stay with good limit effect and convenient operation.

The technical solution adopted by the utility model to solve the technical problems is: the window limit support, including the cantilever 1 and the bottom groove 2, and the sliding device arranged in the bottom groove 2 that can slide along it, the sliding device and the end of the cantilever 1 Connection, the other end of the cantilever 1 is connected with a support piece 3, the sliding device includes a slider 6, a shrapnel 5 and a positioning piece 7, the slider 6 is installed in the bottom groove 2, one end of the shrapnel 5 is installed on the slider 6, and the other end Fixedly connected with the positioning piece 7, the positioning piece 7 is arranged in the inside of the bottom groove 2, and the top of the bottom groove 2 is provided with a plurality of bayonet sockets 4 for the positioning piece 7 to pop out.

The beneficial effect of the utility model is: the cantilever is embedded in the bottom groove through the sliding device, and when the slider moves to the position of the bayonet, the positioning piece is ejected from the bayonet by the action of the shrapnel, and the positioning piece is stuck in the bayonet and cannot continue to move, and the cantilever moves along with the bayonet. Stop the movement, the window is fixed, gently press the positioning piece, the shrapnel moves down into the bottom groove, slides again until the next bayonet, the positioning piece pops out again, the window is fixed again, and so on. When the limit piece is stuck, it is subjected to forces from all directions of the bayonet, which greatly improves the firmness. At the same time, all operations can be realized by lightly pressing the limit piece, which is quite simple.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the front view of the utility model;

FIG. 4 is a partially enlarged view of FIG. 3 .

Detailed ways

Referring to Figures 1 to 4, the window opening stopper includes a cantilever 1 and a bottom groove 2, and a sliding device arranged in the bottom groove 2 that can slide along it, the sliding device is connected to the end of the cantilever 1, and the other end of the cantilever 1 The supporting piece 3 is connected, and the sliding device includes a slider 6, a shrapnel 5 and a positioning piece 7. The slider 6 is installed in the bottom groove 2, one end of the shrapnel 5 is installed on the slider 6, and the other end of the shrapnel 5 is connected to the positioning piece 7. Fixedly connected, the positioning piece 7 is arranged inside the bottom groove 2, and the top of the bottom groove 2 is provided with a plurality of bayonet sockets 4 for the positioning piece 7 to pop out. In actual use, the support piece 3 is fixed on the window leaf, and the bottom groove 2 is fixed on the window frame. When the window is closed, the cantilever 1 overlaps with the bottom groove 2. When the window is opened, the cantilever 1 moves with the window and drives the sliding device Sliding on the bottom groove 2, when the slider 6 slides, the positioning piece 7 moves in the bottom groove 2, the elastic piece 5 is pressed down, when the positioning piece 7 moves to the bayonet 4, the card is ejected by the action of the elastic piece 5 port 4, the positioning piece 7 is stuck on the bayonet 4 and cannot continue to move, the cantilever 1 stops moving accordingly, the window is fixed, press the positioning piece 7 lightly, and enter the bottom groove 2 with the shrapnel moving down, slide again until The next bayonet 4, the positioning piece 7 pops up again, and when the window is fixed again, its opening angle is just changed a little, changing the effect of daylighting and ventilation.

As a further improvement of the utility model, the number of bayonets 4 is four, so that the window can be fixed at four different angles after opening, and the number of bayonets 4 can also be reduced or increased, and the more the number is, the more the window is opened There are more choices of angles.

As a further improvement of the utility model, a button 8 is provided at the connection between the elastic piece 5 and the positioning piece 7, and the button 8 is a big head rivet. When the button 8 is pressed, its smooth circular surface can increase the contact area with the finger , which is convenient for users to operate. In addition, limit blocks 9 are arranged at the bottom of both ends of the bottom groove 2, which can prevent the slider 6 from slipping out of the bottom groove 2 when the sliding speed is too fast, which will cause unnecessary trouble.

The above is only a preferred embodiment of the utility model, but should not constitute a limitation to the utility model, as long as the technical solution equivalent to the utility model is adopted, it should also be within the scope of protection of the utility model.
