Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a bidirectional rotating device. Background Art

[0002] In industrial and agricultural production and daily life, two-way rotating devices are indispensable supporting materials. For example, hinges are mainly used for opening and closing doors or windows inside and outside, and are limited to opening and closing in a single direction, making it difficult to achieve two-way opening and closing. Hinges that open and close in a single direction can only be opened in a single direction. When there are obstacles or other external influences in the opening direction, the doors and windows cannot be opened and closed, which limits the use of doors or windows in different environments and has technical problems such as a narrow scope of use.

[0003] In recent years, with the improvement of fire safety, large supermarkets, warehouses, and farms have an increasing demand for two-way revolving doors. The existing two-way doors that can open in opposite directions have high requirements for the installation position of the hinges, occupy a large area, and cannot be completely fitted at 90° when opened, which is not beautiful. In addition, the manufacturing cost is high and cannot meet the needs of production development. Therefore, the field of mechanical processing urgently needs a lightweight and practical two-way rotating device. Summary of the invention

[0025] The rotating shaft I 1-1 and the rotating shaft II 1-2 are as follows Figure 4 As shown, the rotating shaft I 1-1 and the rotating shaft II 1-2 are large cut cylinders (a circular surface larger than a semicircle is called a large cut circle, and a large cut cylinder refers to a cylinder whose upper and lower circular surfaces are larger than a semicircle);

[0026] The rotating plate 2 is an L-shaped structure. Figure 5 , Figure 6 As shown, a plurality of fixing holes II 4 are provided on the vertical surface of the rotating plate 2, and a rotating hole I 2-1, a rotating hole II 2-2, a rotating path I 5-1, and a rotating path II 5-2 are provided on the plane of the rotating plate 2; the rotating hole I 2-1 and the rotating hole II 2-2 are circular hole structures, the rotating path I 5-1 and the rotating hole I2-1 are connected to form a cavity track, and the rotating path II 5-2 and the rotating hole II 2-2 are connected to form a cavity track;

[0027] Preferably, Figure 1 As shown, the rotation axis I 1-1 and the rotation axis II 1-2 are symmetrically arranged with respect to the central axis;

[0028] The rotating hole I 2-1 and the rotating hole II 2-2 are symmetrically arranged with a central axis therebetween, and the rotating path I5-1 and the rotating path II 5-2 are symmetrically arranged with a central axis therebetween, and the two central axes are on the same axis;

[0029] Preferably, the distance between the center of the rotating axis I 1-1 and the center of the rotating axis II 1-2 matches the distance between the center of the rotating hole I 2-1 and the center of the rotating hole II 2-2. Figure 1 , Figure 4 , Figure 6 As shown, the diameter of the rotating hole I 2-1 is larger than the diameter of the rotating shaft I 1-1, and the diameter of the rotating hole II 2-2 is larger than the diameter of the rotating shaft II 1-2;

[0030] The rotating path I 5-1 and the rotating path II 5-2 are arc hole structures, such as Figure 6 As shown, the arc of the rotating path I 5-1 is concentric with the circle of the rotating hole II 2-2, and the arc of the rotating path II 5-2 is concentric with the circle of the rotating hole I 2-1;

[0031] Preferably, the arc hole gap width of the rotating path I 5-1 or the arc hole gap width of the rotating path II 5-2 is smaller than the upper and lower large cut circle diameters of the rotating shaft I 1-1 or the rotating shaft II 1-2, but larger than the large cut circle thickness, such as Figure 1 , Figure 2 The purpose is to allow the large cut circle of the rotating axis I 1-1 or the rotating axis II 1-2 to pass through, while blocking the entire circular surface from passing through.

Figure 2 As shown, the arc hole gap of the rotation path II 5-2 limits the rotation of the shaft II 1-2 within the range of the rotation hole II 2-2, and the shaft I 1-1 disengages from the rotation hole I 2-1 and slides out along the arc hole gap of the rotation path I 5-1, completing the clockwise rotation of the door panel or window sash; when the door panel or window sash needs to rotate counterclockwise, the rotating plate 2 rotates counterclockwise with the shaft I 1-1 as the axis, and the arc hole gap of the rotation path I 5-1 limits the rotation of the shaft I 1-1 within the range of the rotation hole I 2-1, and the shaft II 1-2 disengages from the rotation hole II 2-2 and slides out along the arc hole gap of the rotation path II 5-2, completing the counterclockwise rotation of the door panel or window sash.
