[0023] Please refer to Figures 1-3 The specific embodiment of the present application provides a positioning wind brace, which comprises a sliding rail 10, a fixed block 20, a sliding block 30 and a connecting rod 40.

[0024] The sliding rail 10 can be mounted on the door frame of the door or window, one end of the connecting rod 40 is hinged to the sliding block 30, and the other end of the connecting rod 40 can be mounted on the door panel or window panel. Alternatively, the sliding rail 10 can be mounted on the door panel or window panel, and the other end of the connecting rod 40 is mounted on the door frame of the door or window.

[0025] The sliding rail 10 has a sliding groove 11, and the fixed block 20 can be fixed in the sliding groove 11 of the sliding rail 10 by a screw 50. The sliding block 30 is arranged in the sliding groove 11 and is in sliding connection with the sliding rail 10, and the sliding block 30 can move relative to the fixed block 20.

[0026] In the embodiment, the fixed block 20 is provided with a slot 21 on one side facing the sliding block 30, and the sliding block 30 is provided with an insertion part 31 which can be inserted into the slot 21 on one side facing the fixed block 20. The side wall 211 of the slot 21 is provided with a first elastic positioning member 212, and the insertion part 31 is provided with a second positioning groove 311 which cooperates with the first elastic positioning member 212.

[0027] The first elastic positioning member 212 can be arranged on two opposite side walls 211 of the slot 21, and the second positioning groove 311 can be arranged on two opposite sides of the insertion part 31.

[0028] During the opening and closing of the door and window, the connecting rod 40 is driven to move, so that the sliding block 30 moves relative to the fixed block 20 relying on the sliding rail 10, the insertion part 31 is inserted into the slot 21, the insertion part 31 is pressed against the elastic positioning member 212 and obtains a certain buffer, the first elastic positioning member 212 enters the second positioning groove 311, and finally the fixed block 20 and the sliding block 30 are fixed relative to each other, so that the door and window are kept at a certain angle. The positioning stay provided by the utility model has the effects of simpler structure and reduced frame thickness.

[0029] It can be understood that in other embodiments, the sliding block 30 can be provided with a slot on one side facing the fixed block 20, and the fixed block 20 can be provided with an insertion part which can be inserted into the slot.
