Abstract

A sliding cover-opening device includes a top support, a sliding-resistant device, and a rotatable cover opening device. The rotatable cover opening device further includes a rotatable pushing cover and a rotating torsional spring. According to the sliding cover-opening device, the rotatable pushing cover can automatically rotate to 90 degrees to open completely after sliding over a certain distance. Also, with the sliding-resistant device, users can experience a sliding feeling by hands.

Claims

1. A sliding cover-opening device, comprising:

a top support located on an upper portion of a main body of a cigarette case, wherein an overall structure of the top support is a hollow frame having a plurality of walls for fixing other elements and a plurality of holes for other elements to extend out;

two side walls of the top support opposite to each other are provided with a pair of sliding grooves, one of the two side walls is provided with a cigarette case snap-fit hole, and the other one of the two side walls is fixedly connected to a spring fixing plate on the cigarette case;

a sliding-resistant device located inside the hollow frame of the top support, wherein the sliding-resistant device comprises a cylindrical spring cap, a spring threaded seat located on a lower portion of the cylindrical spring cap and fixedly connected to the cylindrical spring cap, a cover pushing spring located inside the cylindrical spring cap, and a spring head located on an upper portion of the cylindrical spring cap and connected to the cover pushing spring;

a rotatable cover opening device, wherein the rotatable cover opening device comprises a rotatable pushing cover, a first segment of the rotatable pushing cover is in a form of cover for covering at least a part of an upper surface of the top support, and an end of the first segment is provided with a snap-fit block matched with the cigarette case snap-fit hole;

a second segment of the rotatable pushing cover is a pair of symmetrically separated blocks, each of the separated blocks is provided with a sliding rotating groove, a connection part of the first segment and the second segment is a cylinder body, two ends of the cylinder body are respectively provided with a rotating locating pin, the rotating locating pin is arranged inside one of the sliding grooves, and the locating pin rotates freely and moves horizontally;
