TECHNICAL FIELD

[0001] The utility model relates to a plastic nail technical field especially relates to a novel structure half -open environmental protection half -solid plastic nail. BACKGROUND

[0002] The existing plastic nail, such as Figure 1 As shown in the solid cylindrical setting, commonly used in powder box and other cosmetic boxes, for hinged box cover and box body, one end is fixed, the other end is relatively rotated. In the actual use process, on the one hand, the solid cylindrical plastic nail is easy to break when the box body falls, on the other hand, with the opening and closing of the box cover, the traditional nail as the rotating shaft is easy to wear and tear because of the solid, thereby affecting the positioning. INVENTION CONTENTS

[0003] The utility model discloses a novel structure half -open environmental protection half -solid plastic nail to solve the problems raised in the above background art.

[0004] In order to realize the above object, the utility model adopts the following technical scheme:

[0005] A novel structure half -open environmental protection half -solid plastic nail is used for hinged box cover and box body of cosmetic box, including cylindrical main body and the chamfer set in the both ends of main body, the main body includes the fixed end of one side and the rotating end of the other side, and the both are integrally formed connection, with the plastic nail as the hinge shaft, the fixed end is fixedly embedded in one of box cover and box body, and the rotating end is rotatably sleeved with the other of box cover and box body.

[0006] The fixed end is solid.

[0007] The rotating end is provided with a round hole extending from the end face to the fixed end along the axis; the round hole is provided with a through side groove extending from the axis to the outer wall along the radial direction; and the outer wall of the rotating end is linearly arrayed with a plurality of annular protrusions along the length direction.

[0008] Preferably, the diameter of the round hole is equal to one half of the diameter of the end face of the rotating end, so as to ensure that the rotating end has sufficient elastic deformation space.

[0009] Preferably, the depth of the round hole accounts for two thirds of the length of the main body, and the hinge surface of the box cover and the box body intersects with the round hole, so that when the cosmetic box falls, the shearing force generated by the hinge surface can be absorbed by the deformation of the round hole of the plastic nail, effectively preventing the plastic nail from breaking.

[0010] Compared with the prior art, the novel structure half -open environmental protection half -solid plastic nail has the following beneficial effects:

[0011] This invention features a fixed end and a rotating end at both ends. The rotating end has a circular hole and a side groove. The fixed end is fixedly engaged within the hinge shaft hole of the cosmetic box and does not rotate relative to the hinge shaft hole. The rotating end is sleeved within the hinge shaft hole, with its annular protrusion abutting against the inner wall of the hinge shaft hole, reducing the contact area for easier rotation, minimizing wear, and maintaining stable hinge positioning. Furthermore, the circular hole and side groove absorb the shear force generated on the hinge surface when the cosmetic box is dropped, effectively preventing the plastic nails from breaking.

[0016] The following detailed description illustrates the specific implementation method:

[0017] Example 1

[0018] like Figures 2-3 As shown in the figure, this embodiment demonstrates a novel semi-open environmentally friendly semi-solid plastic nail 3, which is used to hinge the lid 1 and body 2 of a cosmetic box. It includes a cylindrical body 4 and chamfers 5 set at both ends of the body 4. The chamfers 5 facilitate the positioning and insertion of the plastic nail 3 during installation.

[0019] The main body 4 includes a fixed end 41 on one side and a rotating end 42 on the other side, which are integrally formed and connected. Using the plastic nail 3 as a hinge axis, the hinge between the lid 1 and the body 2 is achieved through the plastic nail 3. At this time, the fixed end 41 is fixedly embedded in one of the lid 1 and the body 2, and the rotating end 42 is rotatably sleeved with the other of the lid 1 and the body 2. For details, see below. Figure 3 As shown, in this embodiment, the fixed end 41 is fixedly embedded in the hinge shaft hole 11 of the cosmetic box lid, and the rotating end 42 is rotatably sleeved in the hinge shaft hole of the cosmetic box body 2. As the lid 1 and the body 2 open and close, the fixed end 41 and the hinge shaft hole 11 of the cosmetic box lid do not rotate relative to each other, while the rotating end 42 and the hinge shaft hole of the cosmetic box body 2 rotate relative to each other.

[0020] The fixed end 41 is solid in this embodiment. The rotating end 42 is provided with a circular hole 43 extending from the end face to the fixed end 41 along the axis. The circular hole 43 is provided with a through side slot 44 extending from the axis to the outer wall along the radial direction. The circular hole 43 and the side slot 44 can absorb the shear force generated by the hinged surface when the cosmetic box falls, effectively preventing the plastic peg 3 from breaking.

[0021] In this embodiment, the rotating end is provided with a plurality of annular protrusions 45 linearly arranged along the length direction on the outer wall. The rotating end 42 is sleeved in the hinged shaft hole of the cosmetic box body 2. The annular protrusions 45 of the rotating end 42 abut against the inner wall of the hinged shaft hole. When the box body 2 and the box cover 1 are opened and rotated, the annular protrusions 45 can effectively reduce the contact area between the plastic peg 3 and the inner wall of the hinged shaft hole, facilitate rotation, reduce wear, and maintain stable hinged positioning.

[0022] Embodiment 2

[0023] As shown in Figures 2-3 Another embodiment based on embodiment 1 shows a new structure of a semi-open environmentally friendly semi-solid plastic peg 3. Further, in the further implementable manner of this embodiment, the diameter of the circular hole 43 is equal to one half of the diameter of the end face of the rotating end 42, ensuring that the rotating end 42 has sufficient elastic deformation space. If the circular hole 43 is too small to effectively absorb the impact force, the circular hole 43 is too large, resulting in insufficient tension of the rotating end 42, which cannot maintain stable support with the inner wall of the hinged shaft hole, affecting the stability of the plastic peg 3 as the hinged shaft.

[0024] Embodiment 3

[0025] As shown in Figures 2-3 Another embodiment based on embodiment 1 shows a new structure of a semi-open environmentally friendly semi-solid plastic peg 3. Further, in the further implementable manner of this embodiment, the depth of the circular hole 43 is two-thirds of the length of the main body 4. It is necessary to ensure the connection strength between the fixed end 41 and the hinged shaft hole and to ensure that the hinged surface of the box cover 1 and the box body 2 intersects with the circular hole 43. When the cosmetic box falls, the shear force generated by the hinged surface can be absorbed by the deformation of the circular hole 43 of the plastic peg 3, effectively preventing the plastic peg 3 from breaking.

[0026] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. The scope of protection claimed in this application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
