Detailed Description
The invention will be further described with reference to the following figures and examples:
as shown in fig. 1 to 5, the utility model relates to a crank slow descending device for awning, which comprises a main arm base 2 fixedly connected with a housing 1, wherein the end of the main arm base 2 is further provided with a hook 21 connected with the housing 1 in a snap-fit manner, and the hook 21 makes the connection between the housing 1 and the main arm base 2 more firm; a rotating shaft 3 is rotatably mounted in a through hole of the main arm base 2, one end of the rotating shaft 3 is fixedly connected with a main arm hinge 4, a connecting rod 5 is also fixedly connected to the main arm hinge 4, the connecting rod 5 is arranged in parallel with the rotating shaft 3, the other end of the connecting rod 5 penetrates through an arc-shaped groove 22 of the main arm base 2, and the arc-shaped groove 22 ensures that the connecting rod 5 can move in the arc-shaped groove; the end part of the connecting rod 5 far away from the main arm hinge 4 is in threaded connection with a nut 6; the connecting rod 5 is also sleeved with a rubber ring 7, and the rubber ring 7 is positioned between the nut 6 and the main arm base 2;
a spring chuck 8 is fixedly sleeved at the middle part of the connecting rod 5, a slow descending spring 9 is sleeved on the spring chuck 8, the other end of the slow descending spring 9 is positioned in a slow descending spring sleeve 10, the slow descending spring sleeve 10 is of a hollow structure, and the slow descending spring sleeve 10 is in threaded connection with the main arm base 2;
