[0033] As shown in Figure 1 The present embodiment provides a baffle automatic closing structure, which comprises a baffle 1, a connecting assembly 2, a support 3 and a reset assembly 4.
[0034] The baffle 1 is movably fixed on the support 3 through the connecting assembly 2.
[0035] The reset assembly 4 comprises a guide piece 41 and a guide rail 42, one end of the guide rail 42 is fixed on the support 3, the guide rail 42 is provided with an inclined arc-shaped guide surface, one end of the guide piece 41 is fixed on the baffle 1, and the other end is movably abutted on the arc-shaped guide surface.
[0036] Working principle: the baffle 1 is installed on the support 3 through the connecting assembly 2, the baffle 1 can rotate and can also move up and down, when the baffle 1 is opened, the baffle 1 rotates and drives the guide piece 41 to move along the inclined arc-shaped guide surface of the guide rail 42, so that the baffle 1 rotates and moves upward at the same time; then, due to the weight of the baffle 1, the guide piece 41 moves downward along the inclined arc-shaped guide surface, and the baffle 1 is automatically closed.
[0037] The guide member 41 is guided by the inclined arc-shaped guide surface on the guide rail 42, and the baffle 1 is lifted upward along the inclined surface. Due to the self-weight of the baffle 1, the guide member 41 moves downward along the inclined guide rail 4 structure, and the baffle is closed. Compared with the spring return structure, the self-closing structure is simple, convenient to operate, fast in response, smaller in occupied space, and wider in application range.
[0038] Specifically, as shown in the figure, Figure 2 The connecting assembly 2 includes a movable rotating rod 21 and a hinge 22. The movable rotating rod 21 is a stepped shaft structure, is fixed on one side of the baffle 1, and the hinge 22 is fixed on the support 3. The movable rotating rod 21 is movably fixed on the hinge 22.
[0039] In a preferred embodiment, the guide member 41 includes a rotating wheel support 43 and a rotating wheel 44. One end of the rotating wheel support 43 is fixed on the movable rotating rod 21, and the rotating wheel 44 is rotatably fixed on the other end of the rotating wheel support 43. The rotating wheel 44 abuts against the arc-shaped guide surface.
[0040] The rotating wheel support 43 is provided with a bearing, the rotating wheel 44 is installed on the rotating wheel support 43 through the bearing, and the side of the rotating wheel 44 away from the rotating wheel support 43 is provided with a limiting block.
[0041] The reset structure using the rotating wheel rolling reduces friction, improves reset stability, and prolongs the service life of the reset assembly.
[0042] Further, the movable rotating rod 21 includes a fixed section 23 and a connecting section 24. The hinge 22 is provided with a mounting hole matched with the shape of the connecting section 24. The diameter of the fixed section 23 is greater than that of the connecting section 24.

[0047] Further, the circular arc guide surface of the guide rail 42 is a rotating uphill structure, and the upward inclination angle of the circular arc guide surface is 30-35 degrees.
[0048] The rotating uphill structure of the circular arc guide surface is arranged on the guide rail, and the inclination angle of the uphill circular arc guide surface is 30-35 degrees, which ensures the self-closing stage of the baffle and the smooth rolling of the runner along the circular arc guide surface for self-closing, ensuring the reliability of the reset assembly.
[0049] The limit block is arranged on the runner, and the limit block is located on the side of the runner where the baffle is located after being automatically closed, thereby limiting the movement path of the runner and improving safety.
[0050] As shown in Figure 2 The embodiment provides a more specific implementation, an automatic closing structure which comprises a baffle, a fixed plate, a guide rail, a runner, a runner support, a movable rotating rod, a limit block, a bearing, a support, and a hinge.
[0051] The two fixed plates and the baffle are fixed together by screws, which makes them more solid; the other side of the fixed plate is welded with the movable rotating rod by electric welding, which makes installation more convenient. The hinge and the support are installed together, and are also installed by screws, which is convenient for disassembly and maintenance in the later period. The hinge on the support is used to install the movable rotating rod, and lubricating oil can be applied in the through hole during installation to reduce friction and make installation more convenient. The movable rotating rod is designed to be thin at both ends and thick in the middle, and the thick part in the middle is supported on the circular through hole of the lower fixed plate, which can prevent the rotating rod from falling and effectively increase its strength.
[0052] A runner support is welded below the movable rotating rod, and the runner and the runner support are installed together by bearing connection, and a limit block is installed behind the runner to prevent the runner from falling off during work.
[0053] A spiral uphill track is installed on the support, and when the structure is used, the runner will move along the spiral uphill track, and when the baffle is completely opened, the structure will stop moving; the baffle will be forced downward by gravity when it is loosened. At this time, the runner will move back along the initial route, and the reciprocating operation can realize the automatic closing of the structure. The automatic closing structure is simple, convenient to install, low in cost, and convenient for use in production and life.
[0054] The preferred embodiments of the present application are described in detail above. It should be understood that those skilled in the art can make many modifications and changes without creative labor based on the concept of the present application. Therefore, any technical solutions obtained by logical analysis, reasoning or limited experiments based on the existing technology within the concept of the present application shall be within the protection scope defined by the claims.
