Preferably, the inhaul cable is a flat braided belt.

The embodiment of the utility model provides a box-packed sunshade is still provided, adopt as above arbitrary one a box-packed folding crank arm of cranking arm sunshade. Specifically, as shown in fig. 11, the box-packed awning includes a box body composed of a box body base 210, an upper cover 220 and a lower cover 230, and parts such as a folding crank arm, an awning scroll 300, an awning cloth 400, etc. are integrally installed inside the box body; one end of the folding crank arm is fixedly installed on the box body base 210 through the crank arm rear seat 110, the lower cover 230 is connected with the other end of the folding crank arm, and meanwhile, the lower cover 230 also serves as a traction rod of the tarpaulin 400.

In practical use, when the awning reel 300 does not apply a pulling force to the awning cloth 400, the crank arm 150 is unfolded under the action of an elastic guy cable structure in the crank arm 150, so that the lower cover 230 is driven to be unfolded, the awning cloth 400 is pulled out of the awning reel 300 and spread out under the traction of the lower cover 230, at the moment, due to the gravity action of the crank arm 150, the crank arm connecting piece 120 rotates downwards relative to the crank arm rear seat 110 until being blocked by the limiting protrusion 131, so that the unfolded crank arm 150 has a certain inclination angle relative to the horizontal plane, namely, the awning cloth 400 has a certain inclination angle relative to the horizontal plane when being unfolded, and the inclination angle can be adjusted by adjusting the distance between the limiting protrusion 131 and the crank arm rear seat 110. At this time, the stop cam 160 rotates relative to the crank arm link 120 until the protruding portion thereof is far away from the crank arm link 120, the stop cam 160 abuts against the stop pin 141, the stop cam 160 does not apply an acting force to the stop pin pushing rod 143, the stop pin 141 moves under the action of the elastic member 142 to be inserted into the stop groove 132 on the adjusting lever, so that the relative positions of the crank arm link 120 and the crank arm rear seat 110 are fixed, thereby ensuring that the inclination angle of the crank arm 150 remains unchanged, stably supporting the tarpaulin 400, and smoothly unfolding the tarpaulin 400.

When the tarpaulin 400 needs to be retracted, the awning reel 300 applies a pulling force to the tarpaulin 400, the tarpaulin 400 is wound on the awning reel 300, along with the retraction of the tarpaulin 400, the acting force of the tarpaulin 400 on the crank arm 150 is greater than the acting force of the elastic guy cable structure on the crank arm 150, and the crank arm 150 is folded and folded under the acting force of the tarpaulin 400; at this time, the stop cam 160 rotates relative to the crank arm connecting member 120 until the protruding portion thereof is close to the crank arm connecting member 120, the stop cam 160 pushes the stop pin pushing rod 143 to move, and further pushes the stop pin 141 located inside the crank arm connecting member 120 to slide, so that the stop pin 141 is separated from the stop groove 132 on the angle adjusting lever 130, the crank arm connecting member 120 and the crank arm rear seat 110 can rotate relative to each other, so that the crank arm 150 is finally attached to the crank arm rear seat 110, and the lower cover 230 disposed on the crank arm can be closely attached to the upper cover 220 and the box body base 210, thereby forming a seamless folded box body.

Although terms such as crank arm awning, crank arm rear seat crank arm connecting member, angle adjusting lever, limit projection, stop groove, stop pin, elastic member stop cam, eccentric wheel, box body base, upper cover, lower cover, awning scroll, awning cloth, etc. are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
