The parallel arrangement and the inclination of splint can consult prior art, and the hinge hole is used for supplying the articulated pivot to pass through, and the annular boss that splint lateral surface set up does benefit to the support length that increases the articulated pivot, and then improves assembly stability.
In the hinge part of the sunshade hanging umbrella, the joint of the fork arm part and the plug-in part is provided with a limit step surface which is arranged around the plug-in part. Therefore, the limiting step surface can form limiting propping with the end face of the pipe column after the inserting part is inserted in place, the through hole is accurate in place, and convenience in assembly is guaranteed.
In the hinge part of the sunshade hanging umbrella, the edge of the inner side surface of the clamping plate is provided with a step groove which is arranged along the edge. Thus, the contact friction area between the inner side surface of the clamping plate and the umbrella body part is reduced, and further friction loss is reduced under the condition of ensuring smooth angle adjustment.
Compared with the prior art, the utility model has the following advantages:
When the hinged part of the sunshade hanging umbrella is assembled and installed, a connecting piece with larger specification can penetrate through the installation hole of the pipe column and the through hole closest to the fork arm part, the connecting piece with common specification is penetrated through the other through hole, the connecting piece close to the fork arm part when the fork arm part is subjected to deflection load of the umbrella body can bear larger load due to shorter moment arm away from the fulcrum, and the connecting piece in the other through hole has lower strength requirement due to smaller bearing load, so that the assembly stability of the hinged plug is improved by more reasonable structural design.
