Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a speed-limiting automatic door opening and closing structure comprises a door frame 1 and a door 3, wherein the door frame 1 comprises two vertical sections and a horizontal section, and the vertical section of the door frame 1 is rotatably connected with one end of the door 3; as shown in fig. 3, a driving member is arranged on one side of the lower portion of the vertical section, which is located indoors, an output shaft of the driving member is fixedly connected with one end of a horizontal rod, the horizontal rod rotates on the horizontal plane, a buckling member 4 is installed at the bottom end of the door frame 1, the other end of the horizontal rod is rotatably connected with one end of a pulling rod 10, the other end of the pulling rod 10 is rotatably connected with the middle of a connecting rod 5, one end of the connecting rod 5 is rotatably connected with the door frame 1, the other end of the connecting rod 5 is detachably connected with the bottom end of the door 3 through the buckling member 4, the buckling member 4 and the connecting rod 5 are separated due to excessive stress of the connecting rod 5, the driving member drives the horizontal rod to rotate horizontally.
Specifically, as shown in fig. 2, fastener 4 includes adjusting nut 7, compression spring 8 and driving lever 9, the ascending circular slot of opening has been seted up to the bottom of door 3, the upper portion of circular slot inner wall is seted up threadedly, the lower extreme threaded connection of the screw thread of circular slot inner wall and adjusting nut 7, the top and the adjusting nut 7 fixed connection of driving lever 9, the bottom of driving lever 9 runs through and extends to the below of circular slot, the cover is equipped with compression spring 8 on the driving lever 9 between 7 bottoms of adjusting nut and the inside bottom side of circular slot, the one end that driving lever 9 was kept away from to connecting rod 5 has seted up the joint groove, the joint inslot is inserted to the bottom of driving lever 9.
Further, the bottom end of the shift lever 9 is provided with an arc-shaped section, and the arc-shaped section is not completely inserted into the clamping groove of the connecting rod 5.
Further, the inside diameter of the catching groove is gradually reduced from top to bottom.
When the rotating speed of the speed reducer is too fast or the door is blocked during opening and closing of the door, the connecting rod 5 is stressed too much, the deflector rod 9 is separated from the connecting rod 5, the door 3 loses an external force to stop rotating, and the safety of the speed-limiting automatic door opening and closing structure is ensured.
The deflector rod 9 is matched with the connecting rod 5 by an inclined plane, the inclined plane has a component force which enables the deflector rod 9 to be upwards separated from the matched inclined plane, and the deformation length of the compression spring 8 is adjusted by adjusting the overlapping length of the adjusting nut 7 and the circular groove at the bottom end of the door 3, so that the component force of the matched inclined plane required by the deflector rod 9 when the deflector rod 9 is separated from the connecting rod 5 is adjusted, and the applicability of the speed-limiting automatic door opening and closing structure is improved.
The vertical section of the door frame 1 and one end of the door 3 of the present embodiment are connected by a hinge 2.
The driving piece of this embodiment includes reduction gear and driving motor 6, and the input shaft of reduction gear and driving motor 6's output shaft pass through the coupling joint, and the one end fixed connection of connecting rod 5 is kept away from to the output shaft and the horizon bar of reduction gear, and driving motor 6's input and external power source's output electricity are connected, and driving motor 6 drives the horizon bar horizontal rotation through the reduction gear, and the horizon bar drives door 3 through pulling rod 10, connecting rod 5 and buckling piece 4 and opens and shuts.
When in use:
the door frame 1 is fixed with the ground or a wall body, the door 3 freely rotates around the hinge 2, the door 3 is connected with the connecting rod 5 through the buckling piece 4, the driving motor 6 works, the driving motor 6 drives the horizontal rod to rotate on the horizontal plane through the speed reducer, and the horizontal rod drives the door 3 to open and close through the pulling rod 10, the connecting rod 5 and the buckling piece 4; the moving connecting rod 5 drives the door 3 to open and close through the matching of the clamping groove on the connecting rod 5 and the arc-shaped section of the deflector rod 9, and the door 3 rotates around the hinge loose leaf 2;
because the door has inertia force from the static rotation, the faster the door rotates, the larger the inertia force, the higher the shift lever 9 needs to apply a larger force on the door 3 to make the door 3 rotate around the hinge 2, because the shift lever 9 and the connecting rod 5 are matched by an inclined plane, the inclined plane has a component force F which makes the shift lever 9 separate from the matched inclined plane upwards, the component force F is balanced by the elasticity of the compression spring 8, when the inertia force of the door 3 is gradually increased, the component force F is increased, when the component force F is larger than the elasticity of the compression spring 8, the shift lever 9 moves upwards, the shift lever 9 separates from the connecting rod 5, and the door loses the external force to stop rotating.
When the rotating speed of the speed reducer is too fast or the door is blocked when the door is opened, the connecting rod 5 is stressed too much, the deflector rod 9 is separated from the connecting rod 5, the door 3 loses the external force to stop rotating, and the safety of the speed-limiting automatic door opening and closing structure is ensured;
the deflector rod 9 is matched with the connecting rod 5 by an inclined plane, the inclined plane has a component force which enables the deflector rod 9 to be upwards separated from the matched inclined plane, and the deformation length of the compression spring 8 is adjusted by adjusting the overlapping length of the adjusting nut 7 and the circular groove at the bottom end of the door 3, so that the component force of the matched inclined plane required by the deflector rod 9 when the deflector rod 9 is separated from the connecting rod 5 is adjusted, and the applicability of the speed-limiting automatic door opening and closing structure is improved.
