[0029] Reference Figures 1 to 3 The present invention provides a flip-top cosmetic box, comprising: a base 100, a cover 200 and a plastic shaft member 300, wherein the base 100 and the cover 200 are respectively provided with a first shaft hole 110 and a second shaft hole 210 for the plastic shaft member 300 to pass through, the first shaft hole 110 and the second shaft hole 210 having the same aperture size and being concentrically arranged, and the plastic shaft member 300 is sequentially arranged with a first contact section, a connecting section 310 and a second contact section along its length direction, the connecting section 310 being used to connect the junction of the first shaft hole 110 and the second shaft hole 210, the first contact section and the second contact section are both formed with at least two circles of flexible sheets 320 spaced apart along their length direction, the flexible sheets 320 protruding from the outer peripheral wall of the plastic shaft member 300 so that the flexible sheets 320 can elastically abut against the inner wall of the first shaft hole 110 or the second shaft hole 210.

[0030] The flip-top cosmetic box of the above structure utilizes a plastic shaft 300 that is inserted through the first and second shaft holes 110 and 210 to realize the rotation of the cover 200 relative to the base 100. The flexible sheet 320 elastically abuts against the inner wall of the first and second shaft holes 110 and 210 to prevent the plastic shaft 300 from moving axially and radially. When the cover 200 rotates relative to the base 100, a damping feel can be generated, which simplifies the structure of the rotating shaft and reduces the precision requirements for the rotating shaft. In addition, there will be no abnormal sound of metal friction when turning the switch. It is understandable that when the cover 200 rotates relative to the base 100, the following two situations may occur: the first is that the flexible sheet 320 on the first contact section is tightly matched with the first shaft hole 110, and the flexible sheet 320 on the second contact section rotates relative to the second shaft hole 210; the second is that the flexible sheet 320 on the second contact section is tightly matched with the second shaft hole 210, and the flexible sheet 320 on the first contact section rotates relative to the first shaft hole 110. Both situations can prevent the plastic shaft 300 from moving in the axial and radial directions, thereby ensuring the stability and reliability of the rotation of the cover 200 relative to the base 100.

[0031] See also Figure 2 and Figure 3In some embodiments of the utility model, the plastic shaft piece 300, the first shaft hole 110 and the second shaft hole 210 are all cylindrical, the positions of the plastic shaft piece 300 corresponding to the flexible sheet 320 are all provided with annular grooves 330 recessed inward along the outer peripheral wall thereof, and the flexible sheet 320 is protruded radially outward from the groove bottom of the annular groove 330 to the plastic shaft piece 300 to form an annular shape. When the flexible sheet 320 is elastically deformed, it can abut against each position of the inner peripheral wall of the first shaft hole 110 or the second shaft hole 210, further stabilizing the position of the plastic shaft piece 300 in the first shaft hole 110 and the second shaft hole 210. When the flexible sheet 320 is elastically deformed, the annular groove 330 provides a space for the flexible sheet 320 to bend.

[0032] Referring to Figure 3 In some embodiments of the utility model, the diameter size of the plastic shaft piece 300, the first shaft hole 110 and the second shaft hole 210 is A, and the diameter size of the flexible sheet 320 is B, which satisfies: 1.05A≤B≤1.1A. It should be noted that when the above size relationship is satisfied, the diameter size of the flexible sheet 320 is slightly larger than the diameter size of the second shaft hole 210, which can prevent the face cover 200 from being difficult to open due to excessive damping under the premise of limiting the axial movement and radial movement of the plastic shaft piece 300 and generating a damping feel.

[0033] In some embodiments of the utility model, the thickness size of the flexible sheet 320 is 0.2mm to 0.6mm. It should be noted that when the thickness size of the flexible sheet 320 satisfies the above requirement, the flexible sheet 320 can generate appropriate elastic abutment force to contact the first shaft hole 110 and the second shaft hole 210, avoiding the occurrence of the case that the elastic abutment force is too small or too large.

[0034] Referring to Figure 2 and Figure 3 In some embodiments of the utility model, the end of the first contact section and the end of the second contact section between the two adjacent annular grooves 330 are provided with a support cylinder 340 in contact with the first shaft hole 110 or the second shaft hole 210. It should be noted that the support cylinder 340 is partially supported on the inner peripheral wall of the first shaft hole 110 and the second shaft hole 210, avoiding the situation that the plastic shaft piece 300 rotates smoothly only by relying on the elastic deformation of the flexible sheet 320.

[0035] In some embodiments of the utility model, the length size of the supporting cylinder 340 is 3 to 10 times of the thickness size of the flexible sheet 320. It can be understood that the supporting cylinder 340, the flexible sheet 320 and the plastic shaft 300 are integrated plastic structure, when the length size of the supporting cylinder 340 along the axial direction of the plastic shaft 300 is 3 to 10 times of the flexible sheet 320, it is favorable to prevent the plastic shaft 300 from deforming in the radial direction relative to the first shaft hole 110 and the second shaft hole 210.

[0036] Referring to Figure 1 And Figure 2 In some embodiments of the utility model, the base 100 has two side protrusions 120 arranged face to face, the cover 200 is provided with a protruding strip 220 between the two side protrusions 120, and each side protrusion 120 is provided with a first shaft hole 110 horizontally penetrating through. The two ends of the protruding strip 220 are both inwardly formed with counterbores constituting the second shaft hole 210. That is, the plastic shaft 300 is provided with two, and the length size of each plastic shaft 300 is relatively short. One end of the plastic shaft 300 is inserted into the counterbores, and the other end is inserted into the first shaft hole 110.

[0037] Referring to Figure 2 In some embodiments of the utility model, in order to facilitate the installation of the plastic shaft 300, the end of the first shaft hole 110 away from the second shaft hole 210 is provided with a counterbore 130 for guiding the insertion of the plastic shaft 300. The user can apply an axial pushing force to the plastic shaft 300 to align the position of the counterbore 130 and insert the plastic shaft 300 into the first shaft hole 110 and the second shaft hole 210.

[0038] Referring to Figure 4 In some embodiments of the utility model, in order to avoid the cosmetic box placed in the bag from accidentally opening the cover 200, a limiting mechanism is arranged between the base 100 and the cover 200 to stabilize the cover 200 on the base 100.

[0039] Referring to Figure 4In some embodiments of the utility model, the limiting mechanism includes the convex arc part 410 arranged on the base 100 and the buckle part 420 arranged on the face cover 200 and matched with the convex arc part 410, one side of the convex arc part 410 is equipped with the limiting plane 430, the buckle part 420 can cross the convex arc part 410 and elastically abut on the limiting plane 430. Wherein, the clearance fit between the buckle part 420 and the limiting plane 430, the interference fit between the buckle part 420 and the convex arc part 410, thus need to exert the greater torsion force can open the face cover 200, when the buckle part 420 leaves the convex arc part 410 and the limiting plane 430, can rely on the cooperation between the plastic shaft piece 300 and the first shaft hole 110 and the second shaft hole 210 to realize the rotation and the damping hand feeling of the face cover 200.

[0040] The technical features of the above embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combination of these technical features does not exist contradictory, should be considered as the range of the present application.

[0041] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that: without departing from the principles and purposes of the utility model, can make various changes, modification, replacement and modification to these embodiments, the scope of the utility model is defined by the claims and its equivalents.
