Sunshade

A sunshade, comprising:

• a honeycomb component, wherein the honeycomb component is connected with several umbrella ribs, and the honeycomb component is configured to control opening and closing of the umbrella ribs;
• a first center rod, wherein the honeycomb component sleeves the first center rod, and the first center rod is provided with a first through hole;
• a second center rod, wherein the first center rod sleeves the second center rod, and the second center rod slidably expands to an extended position or a contracted position within the first through hole;
• and
• a locking device, wherein the second central rod is locked at the extended position or the contracted position through the locking device;
• wherein the honeycomb component comprises an upper honeycomb fixedly sleeving an upper end of the first central rod and a middle honeycomb movably sleeving the first central rod;
• a pressure reducing bushing is sleeved between the upper honeycomb and the middle honeycomb;
• the umbrella ribs comprise main frames and auxiliary frames;
• the main frames are hinged with the upper honeycomb;
• one auxiliary frame is connected between each of the main frames and the middle honeycomb;
• one end of the auxiliary frame is hinged to a middle part of the main frame;
• and the other end of the auxiliary frame is hinged to the middle honeycomb;
• wherein the honeycomb component further comprises a lower honeycomb movably sleeving the first central rod and located below the middle honeycomb;
• one pull rod is connected between each of the auxiliary frames and the lower honeycomb;
• one end of the pull rod is hinged to the auxiliary frame;
• and the other end of the pull rod is hinged to the lower honeycomb;
• wherein the lower honeycomb is provided with a chamber;
• a second spring is sleeved between the middle honeycomb and the lower honeycomb;
• one end of the second spring fixedly abuts against a bottom of the middle honeycomb, and the other end of the second spring is connected to the lower honeycomb and is partially located in the chamber;
• the lower honeycomb is provided with a holding part;
• and antiskid lines are arranged on an outer circumference of the holding part;
• wherein the sunshade further comprises an umbrella head, the umbrella head fixedly sleeves a bottom end of the second center rod;
• a clamping part is arranged below the holding part;
• and the clamping part slides to the umbrella head and is connected to the umbrella head through a buckle;
• wherein a minimum inner diameter of the clamping part is less than a minimum inner diameter of the stop sleeve, so that when the clamping part slides towards the umbrella head, the clamping part abuts against the stop sleeve and drives the stop sleeve to be locked to the umbrella head;
• and at the moment, the first center rod and the second center rod are located at the contracted position.
