Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Referring to fig. 1 to 6, in a specific embodiment, a hand-clamping prevention mechanism for a sliding window sash comprises a screen window 2 slidably disposed in a window frame 1; an elastic bracket 3 for preventing the screen window 2 from closing is arranged in a screen window groove 12 at the inner side of the window frame 1; the elastic support 3 is formed by mutually hinging the front end of a first support rod 32 and the tail end of a second support rod 33, and a torsion spring 36 is arranged at the hinged position; the tail end of the first support rod 32 is hinged in the window screen groove 12, and the front end of the second support rod 33 is provided with a roller 34; the roller 34 is seated on the screen rail groove 5 at the bottom of the window frame 1.

The screen window 2 generally comprises a screen window frame and a screen surface, and the screen surface is arranged in the screen window frame; the elastic support 3 is generally directly arranged in a screen window track groove 5 at the bottom of the window frame; the torsion spring 36 mainly realizes the opening of the first support bar 32 and the second support bar 33; when the screen 2 collides with the roller 34, the angle between the first support bar 32 and the second support bar 33 is reduced, the torsion spring 36 generates torsion to absorb collision potential energy, and then the screen 2 stops moving.

As shown in fig. 2, in order to facilitate the installation of the elastic support, as a preferred embodiment of the present invention, the tail end of the first support rod 32 is hinged with a mounting plate 31; the mounting plate 31 is fixed to the window screen slot 12.

As shown in fig. 2-3, when the screen window is required to be folded with the screen window groove 12, the elastic bracket 3 cannot prevent the screen window from moving, so that the elastic bracket 3 needs to be put into the accommodating hole 11, and as a preferred embodiment of the present invention, the accommodating hole 11 for accommodating the elastic bracket 3 is arranged in the screen window groove 12.

As shown in fig. 3, in order to smoothly store the elastic bracket 3 in the storage hole 11 without affecting the matching of the screen window 2 and the screen window groove 12, as a preferred embodiment of the present invention, the mounting plate 31 is located below the storage hole 11.

As shown in fig. 2, in order to make the elastic support 3 prevent the screen window from moving for a long distance, as a preferred embodiment of the present invention, the first support rod 32 and the second support rod 33 form an inverted V shape, and the included angle is an obtuse angle.

As shown in fig. 4, in order to make the first support bar 32 and the second support bar 33 coincide as much as possible when being folded, as a preferred embodiment of the present invention, the front end of the first support bar 32 is provided with a U-shaped groove 35; the tail end of the second supporting rod 33 is hinged in the U-shaped groove 35.

In order to prevent the elastic support 3 from bouncing off the screen window when the elastic support collides with the screen window, as a preferred embodiment of the present invention, the roller 34 is made of a magnetic material; the side surface of the screen window 2 is provided with an iron sheet 4 for absorbing the roller 34.

The roller 34 is made of magnetic materials, and has the following advantages: after the elastic support 3 is stored in the storage hole 11, the screen window 2 and the screen window groove 12 are closed, when the screen window 2 is moved out again, the elastic support 3 can be automatically sucked out through the iron sheet 4, and therefore the elastic support 3 does not need to be manually taken out from the storage hole 11.
