Crank arm awning pitching angle adjusting mechanism
The invention discloses a pitching angle adjusting mechanism of a crank arm awning. The pitching angle adjusting mechanism comprises a wall seat, a crank arm and a hinged support connected between the wall seat and the crank arm. An adjusting screw rod is arranged between the wall seat and the hinged support, and the screw-thread fit distance between the adjusting screw rod and the adjusting nut can be changed by rotating the adjusting screw rod so as to adjust the pitching angle of the unfolded crank arm; the hinged support is provided with a U-shaped pin capable of transversely and elastically moving, and a reset spring is arranged between the U-shaped pin and the hinged support. When the crank arm is unfolded, the U-shaped pin plays a double-locking function, namely locking the adjusting function of the adjusting screw rod and locking the moving capacity of the hinged support, so that the position of the hinged support is locked, the hinged support cannot rotate no matter how large the external acting force is, the crank arm is prevented from shaking up and down under the action of wind power, and the service life of the crank arm is prolonged. And damage to the matching relation between the adjusting screw rod and the adjusting nut due to external force is also avoided, so that the structure of the whole mechanism is more stable and firmer, and the service life is longer.
本发明公开了一种曲臂遮阳篷仰俯角调节机构，其包括包括壁座、曲臂以及连接于所述壁座和曲臂之间的铰座；壁座和铰座之间设有调节螺杆，转动所述调节螺杆，可改变调节螺杆与调节螺母螺纹配合距离以调节曲臂展开的仰俯角；铰座设有可横向弹性移动U型销，所述U型销与铰座之间设有复位弹簧；曲臂展开的同时，U型销起到了双重锁定功能，第一是对调节螺杆调节功能的锁定，第二是对铰座活动能力的锁定，因此铰座的位置被锁死，无论外部作用力多大，都不能使其发生旋转，从而避免了曲臂受风力作用发生上下晃动，也避免因外力作用对调节螺杆和调节螺母之间配合关系的破坏，使得整个机构的结构更加稳定牢靠，使用寿命更长。
