In addition, the up, down, left, right and other descriptions used in the present application are only relative to the mutual position relationship of the components of the present application in the drawings.

[0040] Referring to Figures 1 to 10 A windproof door positioning device, comprising a guide positioning seat 1, a movable support 2 and a support fixed seat 3; the guide positioning seat 1 is arranged on the door panel 41; the support fixed seat 3 is arranged on the door frame 42 or the cabinet 43; the first end A1 of the movable support 2 is connected with the support fixed seat 3, and the first end A1 of the movable support 2 is provided with a first anti-falling fastener 61 for anti-falling connection of the first end A1 of the movable support 2; the guide positioning seat 1 has a guide positioning groove 11, the second end A2 of the movable support 2 is connected with the guide positioning groove 11, and the second end A2 of the movable support 2 is provided with a second anti-falling fastener 62 for anti-falling connection of the second end A2 of the movable support 2; the guide positioning groove 11 comprises a guide groove 111 and a positioning groove 112; the guide groove 111 has a first end B1 and a second end B2, the second end B2 of the guide groove 111 is closer to the rotating side D of the door panel 41 than the first end B1, and the positioning groove 112 is connected with the second end B2 of the guide groove 111 at a set angle C; the guide groove 111 is used for guiding the movable support 2 when the door is opened and closed (such as sliding guiding); the positioning groove 112 is used for supporting and positioning the movable support 2 after the door opening angle is opened to the position.

[0041] Referring toFigures 1 to 10 In one embodiment, the guide positioning seat 1 is a "U" shaped piece 12 of a set length, which includes a side plate 121, a top plate 122 and a folded edge plate 123; one side of the top plate 122 is provided with the side plate 121, and the other side is provided with the folded edge plate 123; the top plate 122 is provided with the guide positioning groove 11; the side plate 121 is fixedly connected (such as welded) with the door plate 41; after the guide positioning seat 1 is fixed on the door plate 41, the second end B2 of the guide groove 111 is closer to the rotating side D of the door plate 41 than the first end B1. When the second end A2 of the movable support 2 is at the first end B1 or near the first end B1 of the guide groove 111, the movable support 2 does not have a supporting effect, and the door plate 41 can be in a closed state; when the door plate 41 is opened, the second end A2 of the movable support 2 is at the second end B2 of the guide groove 111, which can prevent the door plate 41 from being opened too much, and when the door plate 41 has a slight closing action under the influence of force, the second end A2 of the movable support 2 can (preferentially) slide into the positioning groove 112, at this time, the movable support 2 in combination with the positioning groove 112, plays a supporting and positioning role for the door plate 41, which can avoid the door plate 41 from being closed under the action of wind.
