Description

Technical Field

[0001] The utility model relates to the technical field of optical lens packaging, in particular to an optical lens packaging box. Background Art

[0002] There are two ways to package optical lenses: first, wrap the optical lenses with capacitive paper and then stuff them into pearl cotton. This packaging method can effectively protect the product and has a certain vibration reduction effect. However, when taking out the optical lens, debris is likely to remain on its surface, and it is difficult for users to take the optical lens out of the pearl cotton. Second, place the optical lens directly in the packaging box. However, the current packaging box uses an inclined block to fix the corners of the optical lens. Although this method reduces scratches, the corner force is likely to cause the optical lens to deform when subjected to external pressure.

[0003] CN202321510098.6 discloses a structurally stable optical lens packaging box, comprising a box body and a box cover, wherein a lower accommodating groove is formed on the upper side of the box body, an upper accommodating groove is formed on the lower side of the box cover, the upper accommodating groove and the lower accommodating groove are sealed and connected by a snap-fit ​​structure, an upper inclined block for stably supporting the top edge of the optical lens is formed on the bottom peripheral side of the upper accommodating groove, and a lower inclined block for stably supporting the bottom edge of the optical lens is formed on the bottom peripheral side of the lower accommodating groove. The optical lens packaging box, by limiting the edges and corners of the optical lens, prevents the optical lens from moving in the packaging box; and, except for the edges and corners, other parts of the optical lens are suspended, which can ensure that the mirror surfaces of the optical lens do not contact the packaging box, thereby ensuring that the surface of the optical lens is not scratched; the structure is simple, stable and reliable, and convenient for transportation. However, by fixing the inclined block, one side of the lens may move down along the inclined block, while the other side moves up along the inclined block, and when subjected to external force, the lens is deformed.

[0004] The technical problem to be solved by the utility model is: how to reduce the pressure of the packaging box on the optical lens during packaging or transportation, so as to avoid deformation of the optical lens. Utility Model Content

[0005] The main purpose of the utility model is to provide an optical lens packaging box, which can fix the optical lens in the packaging box by contacting the outer side of the optical lens through multiple limiting bosses, and then contacting the upper and lower surfaces of the optical lens with the notches of the air-avoiding grooves. During packaging or transportation, the pressure of the packaging box on the optical lens is reduced, thereby avoiding deformation of the optical lens.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] An optical lens packaging box comprises a box body and a box cover, wherein the box body is provided with a first groove; the box cover is provided with a second groove matching the first groove; the first groove and the second groove are both provided with air avoidance grooves; the inner wall of the first groove is provided with a plurality of limiting bosses; the plurality of limiting bosses form a accommodating cavity; the optical lens is placed in the accommodating cavity, and the top and bottom of the optical lens are respectively in contact with the notches of the two air avoidance grooves.

[0008] Preferably, third grooves are provided on both sides of the second groove for facilitating the taking and placing of the optical lens; and the third groove is connected to the second groove.

[0009] Preferably, the depth of the first groove is 1 to 2 mm lower than the cylindrical height of the optical lens; the depth of the second groove is 1 to 2 mm.

[0010] In some embodiments of the present invention, the depth of the first groove is 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm lower than the cylindrical height of the optical lens.

[0011] Preferably, the diameter of the first groove is 0.1 to 0.5 mm larger than the diameter of the optical lens; the diameter of the second groove is equal to the diameter of the first groove; and the thickness of the limiting boss is 0.1 to 0.5 mm.

[0012] In some embodiments of the present invention, the diameter of the first groove is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm larger than the diameter of the optical lens. The thickness of the limiting boss is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0013] Preferably, the plurality of limiting bosses are arranged in a circular array on the inner wall of the first groove.

[0014] Preferably, a clamp is provided on the box cover; a fastener is provided on the box body; and the clamp and fastener cooperate to achieve locking of the box cover and the box body.

[0015] Preferably, the box cover is connected to one side of the box body; the box body and the box cover are integrally manufactured by blister forming.

[0016] Preferably, the corners of the first groove, the second groove and the air-avoiding groove are all rounded.

[0017] Compared with the prior art, this solution has the following beneficial effects:

[0018] The packaging box in this case utilizes multiple limiting bosses to contact the outer side surface of the optical lens, so that the outer side surface of the optical lens and the packaging box achieve point contact, reducing the contact area between the outer side surface of the optical lens and the packaging box, and then contacts the upper and lower surfaces of the optical lens through the notches of the air avoidance groove to limit the up and down movement of the optical lens. Moreover, most of the upper and lower surfaces of the optical lens are located in the air avoidance groove. When subjected to external pressure, the air avoidance groove, the first groove, and the second groove first absorb the pressure and deform. Since the optical lens and the inner wall of the air avoidance groove, the inner wall of the first groove, and the inner wall of the second groove are not in direct contact, the deformation of the air avoidance groove, the first groove, and the second groove will not be transmitted to the optical lens, thereby avoiding deformation of the optical lens.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Example 1

[0024] refer to Figure 1-2 An optical lens packaging box comprises a box body 1 and a box cover 2, the box body 1 is provided with a first groove 11; the box cover 2 is provided with a second groove 21 matching the first groove 11; the first groove 11 and the second groove 21 are both provided with a void groove 3; the inner wall of the first groove 11 is provided with a plurality of limiting bosses 12; the plurality of limiting bosses 12 form a accommodating cavity 13; the optical lens is placed in the accommodating cavity 13, and the top and bottom of the optical lens are respectively in contact with the notches of the two void grooves 3.

[0025] In this embodiment, an optical lens with a diameter of 37.8 mm and a cylindrical thickness of 7.0 mm is used. The optical lens is a convex lens with raised arc structures on the upper and lower surfaces.

[0026] The optical lens is placed in the accommodating cavity 13, and the outer side of the optical lens contacts the multiple limiting bosses 12 instead of the first groove 11, so that there is a gap between the optical lens and the first groove 11. The edge of the lower surface of the optical lens overlaps the notch of the air avoidance groove 3 at the bottom of the first groove 11, so that the convex arc structure on the lower surface of the optical lens is located in the air avoidance groove 3 at the bottom of the first groove 11, thereby reducing the contact area between the optical lens and the box body 1, and the edge of the optical lens overlaps the notch of the air avoidance groove 3 at the bottom of the first groove 11, which increases the stability of the optical lens during transportation. The diameter of the second groove 21 is equal to that of the first groove 11. When the box cover 2 is closed, the edge of the upper surface of the optical lens contacts the notch of the air avoidance groove 3 of the second groove 21, so that the raised arc structure on the upper surface of the optical lens is located in the air avoidance groove 3 of the second groove 21, so that after the first groove 11 and the second groove 21 are closed together, the optical lens is fixed, and the contact area between the optical lens and the packaging box is reduced through the action of the air avoidance groove 3 and the limiting boss 12, and there is a gap between the air avoidance groove 3 and the optical lens. When the packaging box is subjected to external force, the outer wall of the air avoidance groove 3 can absorb the external force and deform, but due to the gap, the outer wall of the air avoidance groove 3 will not compress the optical lens when it is deformed, thereby avoiding deformation of the optical lens.

[0027] Secondly, the second groove 21 is provided with a space-avoiding groove 3, which can meet the use of optical lenses with different curvatures and improve versatility.

[0028] Preferably, third grooves 14 are provided on both sides of the second groove 21 for facilitating the taking and placing of the optical lens; the third groove 14 is connected to the second groove 21 .

[0029] In this embodiment, by providing the third groove 14, the fingers of the staff can grasp the two sides of the optical lens through the third groove 14 to take and place, thereby preventing the fingers from touching the surface of the optical lens and affecting the smoothness of the lens.

[0030] Preferably, the depth of the first groove 11 is 1 to 2 mm lower than the cylindrical height of the optical lens; the depth of the second groove 21 is 1 to 2 mm.

[0031] In this embodiment, the depth of the first groove 11 is 6 mm, and the depth of the second groove 21 is 1.5 mm. By setting the depth of the first groove 11 to be smaller than the depth of the optical lens, the staff can more conveniently take and put the optical lens, and in order to fix the optical lens in the packaging box when the box cover 2 and the box body 1 are closed, the second groove 21 on the box cover 2 needs to cover the part of the optical lens protruding from the first groove 11, so that the first groove 11 and the second groove 21 form a space to limit the movement of the optical lens.

[0032] Although the depth of the first groove 11 is smaller than the depth of the optical lens, which makes it easier to take and place the optical lens, if the depth of the first groove 11 is too small, the stability of the optical lens placed in the first groove 11 will deteriorate. Therefore, the most suitable depth of the first groove 11 is 1 to 2 mm less than the cylindrical height of the optical lens.

[0033] Preferably, the diameter of the first groove 11 is 0.1 to 0.5 mm larger than the diameter of the optical lens; the diameter of the second groove 21 is equal to the diameter of the first groove 11; and the thickness of the limiting boss 12 is 0.1 to 0.5 mm.

[0034] In this embodiment, the diameters of the first groove 11 and the second groove 21 are both 38 mm, and the thickness of the limiting boss 12 is 0.3 mm. When the optical lens is placed in the first groove 11, it contacts the limiting boss 12 instead of the first groove 11, thereby reducing the contact area between the optical lens and the packaging box. Moreover, the diameters of the second groove 21 and the first groove 11 are equal, and the part of the optical lens protruding from the first groove 11 will not contact the second groove 21, but contact the edge of the air avoidance groove 3, thereby achieving line contact, while reducing the contact area and maintaining stability when placing the optical lens.

[0035] Preferably, a plurality of limiting bosses 12 are arranged in a circumferential array on the inner wall of the first groove 11. This can make the outer side of the optical lens bear force more evenly, and avoid deformation of the optical lens due to localized concentrated force.

[0036] Preferably, a clamp 22 is provided on the box cover 2 ; a fastener 15 is provided on the box body 1 ; the clamp 22 and the fastener 15 cooperate to achieve locking of the box cover 2 and the box body 1 .

[0037] In this embodiment, the shape of the clamp 22 is an isosceles trapezoid, the length of the upper base is less than the length of the lower base, the upper base of the isosceles trapezoid is connected to one side of the box cover 2, and the shape of the fastener 15 is a T-shaped hole, which is located at a position of the box body 1 corresponding to the clamp 22. After the staff sequentially passes the two lower bottom corners of the clamp 22 through the T-shaped hole, the clamp 22 will be stuck on the fastener 15, thereby realizing the locking of the box cover 2 and the box body 1.

[0038] Preferably, the box cover 2 is connected to one side of the box body 1; the box body 1 and the box cover 2 are integrally manufactured by blister forming.

[0039] In this embodiment, the box cover 2 is connected to one side of the box body 1, and there is no need to find the box body 1 and the box cover 2 to match, and only the box cover 2 needs to be rotated to make the box cover 2 fit on the box body 1, which simplifies the packaging operation. Through the integrated blister manufacturing, the wall thickness of the plastic box does not need to be too thick, which reduces costs and can also reduce shock.

[0040] Preferably, the corners of the first groove 11, the second groove 21 and the air-avoiding groove 3 are all rounded to avoid contact between the corners of the first groove 11, the second groove 21 and the air-avoiding groove 3 and the surface of the optical lens, thereby maintaining the smoothness of the optical lens.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
