[0002] Windows are the main channels for connecting the internal and external spaces of buildings. Their design not only meets the lighting needs of people's daily lives but also has good heat preservation, heat insulation, sound insulation, ventilation, and safety protection performances, etc. Specifically, doors and windows can be divided into: casement windows, sliding windows, folding doors and windows, and rotating doors and windows. Currently, casement windows are used more frequently because they have a larger opening area and better ventilation effect, and are the first choice for many families.

[0003] To limit the opening angle of a casement window, a limiting device is generally added inside the window groove to limit the opening angle of the casement window. Currently, some casement window limiting devices belong to adjustable limiters, that is, by changing the position of one end of the limiting rod, the purpose of adjusting the opening angle is achieved, and the switching method for fixing the position of one end of the limiting rod is usually hand-tightening. This method has certain inconveniences in use. When tightening it, due to insufficient space, it brings certain troubles to the user. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 As shown in the figure, a limiting device for a casement window includes a track 1. On both sides of the surface of the track 1, there are installation parts 2 connected to the casement window. A plurality of card slots 3 are formed on the surface of the track 1. A slider 4 is slidably arranged in the inner cavity of the track 1. An inclined strut 5 used in cooperation with the casement window is rotatably arranged on the surface of the slider 4. A fixing block 6 used in cooperation with the card slot 3 is slidably arranged on one side of the surface of the slider 4. A pushing mechanism 7 is arranged in the inner cavity of the slider 4, and a limiting mechanism 9 for limiting the pushing mechanism 7 is arranged on one side of the inner cavity of the slider 4.

[0020] When the present utility model is in use, by the fitting between the fixing block 6 and the card slot 3, the effect of limiting the position of the slider 4 is achieved. And under the action of the pushing mechanism 7, the fitting state between the fixing block 6 and the card slot 3 can be adjusted. The hand-pulling adjustment method is convenient for the user to use. In addition, under the action of the limiting mechanism 9, the position of the fixing block 6 can be fixed, and the limiting function of the limiter can be released, improving the practicability of the device.

[0021] The pushing mechanism 7 includes a sliding rod 71 fixed to one side of the inner cavity of the slider 4 and a pulling block 73 fixed to the surface of the fixing block 6. The fixing block 6 slides on the surface of the sliding rod 71. A pushing spring 72 is sleeved on the surface of the sliding rod 71. One end of the pushing spring 72 is fixed to the inner cavity of the slider 4, and the other end of the pushing spring 72 is fixed to the surface of the fixing block 6. In this embodiment, through the setting of the sliding rod 71, the pushing spring 72 and the pulling block 73, the user can make the pulling block 73 slide, so that the fixing block 6 slides on the surface of the sliding rod 71, and under the action of the pushing spring 72, the fixing block 6 can be reset.

[0022] A limiting rod 8 is slidably arranged in the inner cavity of the pulling block 73. Both sides of the limiting rod 8 are fixed to the inner cavity of the slider 4. In this embodiment, through the setting of the limiting rod 8, when the pulling block 73 moves, the sliding of the pulling block 73 is limited, improving the stability of the pulling block 73 when moving.

[0023] The limiting mechanism 9 includes a limiting block 91 that slides on the grooved surface of the slider 4. One side of the surface of the limiting block 91 is fixed with a connecting block 92, and the other side of the connecting block 92 is fixed with a pressing block 93. A groove body that cooperates with the connecting block 92 is provided on one side of the surface of the slider 4. In this embodiment, through the settings of the limiting block 91, the connecting block 92, and the pressing block 93, the user can press the pressing block 93, and then, under the action of the pressing block 93, the connecting block 92 drives the limiting block 91 to move downward, thereby releasing the restriction on the pulling block 73.

[0024] Limiting rods 10 are slidably arranged on both sides of the surface of the limiting block 91. Both sides of the limiting rods 10 are fixed in the inner cavity of the slider 4. A return spring 11 is sleeved on the surface of the limiting rods 10. One end of the return spring 11 is fixed in the inner cavity of the slider 4, and the other end of the return spring 11 is fixed on the surface of the limiting block 91. In this embodiment, through the settings of the limiting rods 10 and the return spring 11, it provides a limit for the sliding of the limiting block 91, and under the action of the return spring 11, it can provide support for the movement of the limiting block 91.

[0025] The surface of the limiting block 91 is inclined, and one side of the inclined surface is a concealed design. In this embodiment, through this setting, it is convenient for the pulling block 73 to fit on the surface of the limiting block 91 from the surface of the slider 4, thereby facilitating the pulling block 73 to press the limiting block 91 and making the limiting block 91 move.

[0026] Working principle: Under the action of the mounting member 2, the track 1 can be fixed in the groove of the casement window, and the other end of the stay member 5 is connected to the casement window. The use of the track 1 and the stay member 5 is prior art and will not be elaborated here. In daily use, if the staff needs to change the limiting angle of the device for the window, the pushing mechanism 7 can be used. Use a finger to pull the pulling block 73, and then the fixing block 6 is disengaged from the card slot 3. At this time, the user can slide the slider 4 in the inner cavity of the track 1, thereby achieving the purpose of adjusting the limiting angle of the window. After the position of the slider 4 meets the requirements, the user releases the control of the pulling block 73, and the fixing block 6 finds the nearest card slot 3, and then under the action of the pushing spring 72, the fixing block 6 is reconnected to the card slot 3, thus completing the purpose of angle adjustment. If the user needs to cancel the restriction on the window angle, only need to use the pulling block 73 to make the pulling block 73 contact the limiting block 91 and slide over the surface of the pulling block 73. After the pulling block 73 slides over the limiting block 91, the limiting block 91 can pop up upward under the action of the return spring 11, thereby achieving the purpose of restricting the pulling block 73, and avoiding the fixing block 6 being inserted into the card slot 3, thereby achieving the purpose of restricting the movement of the slider 4.
