Description

A sliding brace for a casement window

technical field

The utility model relates to the technical field of spare parts for doors and windows, in particular to a sliding brace for a casement window.

Background technique

With the continuous development of the construction field, most of the windows of residential buildings now use aluminum alloy casement windows. Casement windows are easy to use, do not occupy indoor space, and have good airtightness and watertightness, which can effectively prevent indoor energy loss and meet the requirements of energy saving and emission reduction. According to the technical requirements of the construction industry, the load-bearing parts of the casement windows can only use sliding braces, and the opening angle of the sliding braces directly limits the opening angle of the casement windows. However, at present, the opening angle of most of the casement window sliding stays is not large, which directly leads to a small opening angle of the casement window, and even makes it difficult to escape by opening the window at a large angle in an emergency, which is not suitable for fire conditions. The requirements of escape; and the opening and closing process of the sliding stay is relatively laborious, which makes the use of the casement window inconvenient.

detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

Embodiment one

As shown in Figures 1 to 3, a sliding brace for a casement window includes a slide rail 1, a support arm 2, a slider 6 and a connecting rod structure, the slide rail 1 is used to be fixedly installed on the window frame, the The bracket arm 2 is used to be fixedly installed on the window sash, the slider 6 is arranged in the chute 10 of the slide rail 1, the connecting rod structure is respectively connected with the slide rail 1, the bracket arm 2 and the slider 6, and the connecting rod The structure and the support arm 2 form a trapezium hinge. In the utility model, the connecting rod structure and the supporting arm 2 form a trapezoidal hinge, so that the connecting rod structure and the supporting arm 2 can move with a large degree of freedom; when the sliding stay is opened, the sliding rail 1 and the supporting arm 2 can be opened relatively Large angle, easy opening and closing, convenient to open the casement window at a large angle.

The connecting rod structure includes a first connecting rod 3, a second connecting rod 4 and a third connecting rod 5; one end of the first connecting rod 3 is hinged to the end of the slide rail 1, and the other end of the first connecting rod 3 is hinged to the second One end of the three connecting rods 5; one end of the second connecting rod 4 is hinged to the slider 6, the other end of the second connecting rod 4 is hinged to the end of the bracket arm 2, the first connecting rod 3 and the second connecting rod 4 cross each other and at the intersection Hinged; the other end of the third connecting rod 5 is hinged to the middle position of the bracket arm 2;

A trapezium hinge is formed between the first connecting rod 3 , the second connecting rod 4 , the third connecting rod 5 and the bracket arm 2 . Here, the first connecting rod 3 , the second connecting rod 4 , the third connecting rod 5 and the supporting arm 2 have relatively small force, which facilitates the opening of the supporting arm 2 .

When the second connecting rod 4 pushes the slider 6 to move along the chute 10 of the slide rail 1, in order to reduce the friction between the second connecting rod 4 and the surface of the slide rail 1, the slider 6 and the second connecting rod 4 Anti-friction block 7 of plastic material is arranged between, and described anti-friction block 7 is slidingly matched with slide rail 1, and second connecting rod 4 is hinged on anti-friction block 7; Described anti-friction block 7 is positioned on slide rail 1 and slide The other side corresponding to the chute 10 of the rail 1, and the anti-friction block 7 is fixedly connected with the slide block 6. In this way, when the second connecting rod 4 pushes the slider 6 to move, the anti-friction block 7 also moves together.

In order to prevent rainwater, dust layer, etc. from entering the chute 10 of the slide rail 1, the chute 10 of the slide rail 1 is respectively provided with waterproof stoppers 8 near the two ends, and the waterproof stopper 8 and the interior of the chute 10 The surfaces are in close contact, and the slider 6 is located between two waterproof stoppers 8 . Here, installing the waterproof block 8 in the slide groove 10 can greatly increase the surface stress of the slide rail 1, and can effectively avoid the deformation of the slide rail 1 during drilling.

The waterproof block 8 is a metal block or a plastic block. In this way, when the waterproof block 8 is damaged due to aging, corrosion and other reasons, it is convenient to replace it.

The waterproof stopper 8 is provided with a through installation hole, and the corresponding position of the slide rail 1 is provided with a conical counterbore 9; through the conical counterbore 9 and the installation hole, a fixing screw is provided. Screws fix the slide rail 1 on the inside of the window frame. Here, the conical counterbore 9 has greater stress than the ordinary round hole, which can effectively avoid the deformation of the slide rail 1 when the fixing screws are tightened. In this embodiment, two pairs of tapered counterbores 9 are provided, and each pair of tapered counterbores 9 includes two tapered counterbores 9 of different shapes.

The other side of the bracket arm 2 corresponding to the first connecting rod 3, the second connecting rod 4 and the third connecting rod 5 is provided with grooves, and the grooves are used to fit the bracket arm 2 into the installation groove of the window sash inside. Here, the bracket arm 2 is installed in the installation groove of the window sash, and is fixed to the window sash by screws, which is more stable than the previous method of fixing the bracket arm 2 and the window sash only by screws.

The groove includes a groove bottom 12 and two groove sides 11 arranged on both sides of the groove bottom 12, the groove sides 11 are bent outward relative to the groove bottom 12, and the groove sides The angle between 11 and the bottom edge 12 of the groove is greater than or equal to 100°. Here, the side edge 11 of the groove of the support arm 2 is bent outward relative to the bottom edge 12 of the groove, so that the support arm 2 avoids fixing parts such as rivets in the installation groove of the window sash during installation, and at the same time greatly improves the structural strength of the support arm 2 .

In order to facilitate the customer to choose to fix the support arm 2 with different screws, the bottom edge 12 of the groove is provided with a plurality of screw holes 13, and the plurality of screw holes 13 are used for installing locking screws or connecting screws. When using clamping screws, the clamping screws are in contact with the installation groove of the window sash, and at the same time will not drill holes on the surface of the installation groove, thereby destroying the structure of the installation groove; while using connecting screws, the connecting screws will drill holes on the surface of the installation groove, And then destroy the mounting groove structure of the window sash, but now the bracket arm 2 is more firmly connected with the window sash.

The maximum included angle between the slide rail and the support arm is greater than 100°. In this way, the maximum opening angle of the casement window adopting the sliding brace is greater than 100°, and people can escape by climbing out of the window in case of fire or other dangerous situations.

Embodiment two

As shown in Figures 4 to 6, the basic structure of this embodiment is the same as that of Embodiment 1, the difference is that the slide rail 1 of this embodiment is longer in length and narrower in width; the sliding brace of this embodiment is suitable for installation on On window frames with narrow width and good waterproof performance.

For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and ideas described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
