[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] Figures 1 to 6 A hinged cover opening and closing structure for a cigarette box according to an embodiment of the present utility model includes:

[0034] The mounting frame 1 is equipped with a movable opening and closing component 2;

[0035] The opening and closing component 2 includes a first movable part 21, a second movable part 22 and a first driving member 23, wherein the first driving member 23 drives the first movable part 21 and the second movable part 22 to move in parallel relative to each other.

[0036] The first movable part 21 and the second movable part 22 are movably connected to the mounting frame 1 via a linear guide rail or an optical axis slider, and are then driven to move by the first drive unit.

[0037] Specifically, racks are provided on the opposite sides of the first movable part 21 and the second movable part 22, and gears are provided on the rotating end of the first driving member 23. When the gears rotate, they drive the racks to move.

[0038] The space between the first movable section 21 and the second movable section 22 is used to fix the tobacco box.

[0039] Both the first movable part 21 and the second movable part 22 are provided with opening and closing elements 3. The opening and closing elements 3 include a second driving member 31 and an opening and closing member 32 provided at the rotating end of the second driving member 31.

[0040] Specifically, the mounting frame 1 is provided with an opening and closing sliding pair, and the opening and closing element 3 is connected to the sliding block of the opening and closing sliding pair, so that the opening and closing element 3 is more stable when in action.

[0041] The opening and closing element 32 comprises a first sliding pair 321 arranged at the end of the second driving element 31 and a suction accessory 322 arranged at the sliding block of the first sliding pair 321, and the sliding block of the first sliding pair 321 reciprocates along the tangent direction of the rotation track of the rotating end of the second driving element 31.

[0042] The suction accessory 322 comprises a mounting rod and a suction disc, and the mounting rod forms a strip-shaped mounting hole for fixing the suction disc, so as to facilitate the position adjustment of the suction disc.

[0043] When the utility model is used, the first movable part 21 and the second movable part 22 are relatively moved and close to the tobacco case after the mounting frame 1 is driven by an external system to move to the tobacco case to be opened, and in this process, since the first movable part 21 and the second movable part 22 are synchronously actuated by the first driving element 23, as long as the position of the first driving element 23 is on the center line of the tobacco case during operation, the opening and closing element 3 can be accurately positioned at a suitable position, and the opening and closing element 3 can accurately open the shake cover in the tobacco case.

[0044] In order to better determine the relative spatial position of the tobacco case and the opening and closing assembly 2, optionally, a clamping plate 4 is further arranged on the first movable part 21 and the second movable part 22 and relatively approaches and moves away with the two movable parts, and the purpose of this structure is that when the tobacco case in the middle is opened, even if there is a deviation in the left and right positions, the clamping plate 4 can be pushed during the process, so that the tobacco case is slightly corrected, and the tobacco case is always located at the middle position in the internal space defined by the first movable part 21 and the second movable part 22.

[0045] The mounting frame 1 is used as a structure for bearing the opening and closing assembly 2, needs to bear the dead weight of the structure and the load generated by the action of the opening and closing assembly 2, and therefore, the structure design aims at being firm, light and small in deformation; optionally, the mounting frame 1 comprises a vertical plate 11, a bottom plate 12 and a connecting plate 13; the vertical plate 11 and the bottom plate 12 are connected to each other perpendicularly through the connecting plate 13, specifically, the vertical plate 11, the bottom plate 12 and the connecting plate 13 are perpendicular to each other and form a space cubic frame, the first movable part 21 and the second movable part 22 are slidably arranged on the bottom surface of the bottom plate 12, and the first driving element 23 is arranged on the bottom plate 12, so that the first movable part 21 and the second movable part 22 are stable in structure and small in deformation when in action due to the large rigidity of the bottom plate 12 in the plane.
