The utility model provides a packing box.

In the embodiment of the present invention, as shown in fig. 1 to 4, the bottom wall 110 of the packing box and the side wall 120 connected to the bottom wall 110, the side wall 120 and the bottom wall 110 together enclose to form a containing cavity for containing a product; the bottom wall 110 is provided at the middle thereof with a first reinforcing region 111 so that the strength of the middle of the bottom wall 110 is greater than that of the edge of the bottom wall 110.

It can be understood that the bottom wall 110 and the side wall 120 of the packing box together form the box body 100 of the packing box, the side wall 120 of the box body 100 and the bottom wall 110 enclose a containing cavity which can be used for containing a product, and in order to ensure the stability of the product as much as possible, the containing cavity of the box body 100 is configured to adapt to the shape of the product, and it can be understood that the inner diameter of the containing cavity is slightly larger than and similar to the outer dimension of the product. According to the mechanics principle, when the box body 100 contains a product, the moment applied to the bottom wall 110 of the box body 100 from the edge to the middle of the bottom wall 110 of the box body 100 is gradually increased, and the moment changes in a substantially linear manner; if the thickness of each region of the side wall 120 and the bottom wall 110 of the box body 100 is uniform, the bottom wall 110 is deformed more and more severely in the direction from the edge to the middle thereof. The first reinforcing region 111 is arranged in the middle of the bottom wall 110 of the box body 100, so that the strength of the middle of the bottom wall 110 of the box body 100 is enhanced, and the deformation phenomenon caused by large moment can be resisted. Specifically, the first reinforcing region 111 may be integrally formed with the bottom wall 110 of the box body 100; or the first reinforcing region 111 and the bottom wall 110 of the box body 100 can be integrated by means of adhesion; still alternatively, the first reinforcing section 111 and the bottom wall 110 of the box body 100 may be fixedly connected by a fastener. It is understood that, in order to further enhance the connection strength between the first reinforcing region 111 and the bottom wall 110 of the box body 100, the first reinforcing region 111 and the bottom wall 110 of the box body 100 may be integrally formed by an integral molding process, for example, the middle thickness of the bottom wall 110 of the box body 100 may be directly thickened during the production process.

The utility model discloses technical scheme sets up first reinforcing area 111 through the middle part at case body 100 diapire 110, makes the thickness that makes diapire 110 middle part be greater than diapire 110's marginal thickness to strengthen the intensity at diapire 110 middle part, when having improved and having held the product in case body 100, the product overweight leads to the problem that diapire 110 middle part is easy to warp.

As shown in fig. 1 to 4, based on the scheme that the first reinforcing region 111 is disposed in the middle of the bottom wall 110 of the box body 100, the magnitude of the moment changes substantially linearly in the direction from the edge of the bottom wall 110 of the box body 100 to the middle of the box body 100, and in order to achieve the effect of relatively uniform deformation of each region of the bottom wall 110 of the box body 100 on the basis of the change of the moment, in this embodiment, the thickness of the first reinforcing region 111 gradually increases in the direction from the edge of the first reinforcing region 111 to the middle of the first reinforcing region 111.

With this arrangement, the thickness of the bottom wall 110 changes substantially linearly from the edge of the first reinforcing region 111 to the middle of the first reinforcing region 111, so that the ratio of the moment applied to each position of the bottom wall 110 to the corresponding thickness is substantially the same, and the deformation degree of each position of the bottom wall 110 is substantially the same, thereby improving the situation that the middle of the bottom wall 110 is excessively deformed relative to the edge of the bottom wall 110.

Specifically, as shown in fig. 1, the surface of the first reinforcement area 111 on the side away from the bottom wall 110 is a cambered surface; alternatively, as shown in fig. 2, the surface of the first reinforcement area 111 on the side facing away from the bottom wall 110 is tapered.

Alternatively, as shown in fig. 3 and 4, in other embodiments, the surface of the side of the first reinforcement region 111 facing away from the bottom wall 110 may also be at least two contiguous planes, at least two of which are symmetrically disposed about the middle of the first reinforcement region 111. Specifically, the two planes may be rectangular, triangular, trapezoidal, or the like.

With reference to fig. 1 to fig. 4, since the bottom wall 110 and the side wall 120 jointly enclose a containing cavity for placing a product therein, in the present embodiment, the first reinforcing region 111 is disposed outside the bottom wall 110 in consideration of the stability of placing the product.

It should be noted that the outer side of the bottom wall 110 refers to a side of the bottom wall 110 facing away from the accommodating cavity, and it is understood that when a product is accommodated in the accommodating cavity, the first reinforcing region 111 is disposed on a side of the bottom wall 110 facing away from the product. By disposing the first reinforcing region 111 outside the bottom wall 110, it can be understood that the inner side of the bottom wall 110 can be disposed with a plane parallel to the horizontal plane, thereby facilitating the stability of the product (especially, the display panel and other plate-like objects). It should be noted that the outer side of the bottom wall 110 refers to the side of the bottom wall 110 facing away from the product.

When the first reinforcing region 111 is disposed outside the bottom wall 110, the middle of the side of the first reinforcing region 111 facing away from the bottom wall 110 may be disposed lower than the bottom end surface of the side wall 120, and may also be disposed higher than or flush with the bottom end surface of the side wall 120. It should be noted that, the utility model discloses "high", "low", "parallel and level" and "bottom face" among the technical scheme are all when the opening direction that the packing box held the chamber up, and the packing box when the first reinforcing area 111 in the diapire 110 outside is located the inboard product below of diapire 110 places the position as the standard, consequently the utility model discloses the terminal surface that lateral wall 120 deviates from the one end that holds chamber opening direction is the bottom face of lateral wall 120 among the technical scheme, and the terminal surface of the other end is the up end.

It can be understood that when the middle portion of the side of the first reinforcing region 111 away from the bottom wall 110 is lower than the bottom end surface of the side wall 120, if the packing box is placed on the ground or the table, the middle portion of the first reinforcing region 111 directly contacts the ground or the table, and the periphery of the packing box does not contact the ground or the table, which may cause the problem that the placement of the packing box is unstable. In order to achieve the effect that the box body 100 can be stably placed, in the present embodiment, the middle of one side of the first reinforcement region 111 facing away from the bottom wall 110 is higher than or flush with the bottom end surface of the side wall 120.

It can be understood that, in the present embodiment, the outer side surface of the bottom wall 110 and the bottom end surface of the side wall 120 are not on the same horizontal plane, and the outer side surface of the bottom wall 110 is higher than the bottom end surface of the side wall 120, that is, the bottom end of the side wall 120 and the bottom wall 110 may form an avoiding cavity opposite to the opening of the accommodating cavity, and the first reinforcement region 111 is disposed in the avoiding cavity. The bottom end surfaces of the side walls 120 of the packing box are in contact with the ground or the table when the packing box is placed on the ground or the table, thereby increasing the stability of the placement of the packing box while overcoming the problem of excessive deformation of the middle portion of the bottom wall 110.

As shown in fig. 5, in the same way, it can be understood that, when the inside of the box body 100 contains the product, and the product has an extrusion force to the sidewall 120, the moment received by the direction from the edge to the middle of the sidewall 120 of the box body 100 also can be gradually increased, the utility model discloses still can set up the second reinforced area 121 in the middle of the sidewall 120 among the technical scheme for the thickness in the middle of the sidewall 120 is greater than the thickness at the edge of the sidewall 120, and then has strengthened the intensity in the middle of the sidewall 120, has improved the ability of resisting the deformation in the middle of the sidewall 120. The second reinforcing region 121 may be integrally formed with the sidewall 120, or the second reinforcing region 121 may be integrally formed with the sidewall 120 by bonding. In order to further enhance the connection strength between the second reinforcement region 121 and the sidewall 120, the second reinforcement region 121 and the sidewall 120 may be integrally formed.

In addition, the geometric body formed by the enclosure of the side wall 120 of the box body 100 and the bottom wall 110 of the box body 100 may be a columnar body or a prism body. For example, for a packing box for holding a display panel, the box body 100 is generally rectangular, the rectangular has 4 sidewalls 120, and the second reinforcing region 121 may be disposed in the middle of two opposing sidewalls 120, or in the middle of each sidewall 120.

By providing the second reinforcement region 121 in the middle of the side wall 120, the thickness of the middle of the side wall 120 is made larger than the thickness of the edge of the side wall 120, so that the strength of the middle of the side wall 120 is enhanced, and the problem that the middle of the side wall 120 is easily deformed when the product has a pressing force on the side wall 120 when the product is accommodated in the box body 100 is improved. It should be noted that, if the first reinforcing region 111 is disposed in the middle of the bottom wall 110, the strength of the middle of the bottom wall 110 of the box body 100 can be enhanced; if the second reinforcing region 121 is arranged in the middle of the side wall 120, the strength of the middle of the side wall 120 of the box body 100 can be reinforced; if the first reinforcing region 111 and the second reinforcing region 121 are provided in the middle of the bottom wall 110 and the middle of the side wall 120, respectively, the strength of the middle of the bottom wall 110 and the middle of the side wall 120 can be improved.

As shown in fig. 5, based on the solution that the middle of the sidewall 120 has the second reinforcing region 121, the second reinforcing region 121 may be a reinforcing rib protruding from the middle of the sidewall 120, or a thickening block connected to the middle of the sidewall 120. The height of the rib or thickened block may be set to be the same as the height of the side wall 120. It is understood that the second reinforcement region 121 has a connection portion 1211 connected to the sidewall 120, and the connection portion 1211 is formed with a chamfer or a rounded corner. By forming the connecting portion 1211 with a chamfer or a fillet, the stress concentration problem at the connection portion between the second reinforcing region 121 and the sidewall 120 can be improved, so as to prevent the occurrence of a crack or chip drop phenomenon between the second reinforcing region 121 and the sidewall 120.

Further, in order to make the packing box have a larger accommodating space and avoid affecting the placement of the product in the box body 100, in this embodiment, the second reinforcing region 121 is disposed outside the sidewall 120. It should be noted that, in the technical solution of the present invention, the side wall 120 is the inner side of the side wall 120 toward the side of the accommodating cavity, and the side wall 120 is the outer side of the side wall 120 away from the side of the accommodating cavity. It will be appreciated that the second reinforcing region 121 provided on the outside of the side wall 120 (especially when the second reinforcing region 121 is of a rib structure) may also serve as a handle portion, so that a user may handle the package by grasping the second reinforcing region 121.

Of course, the second reinforcing region 121 can be disposed on the inner side of the sidewall 120 without affecting the placement of the product.

Referring to fig. 5 and 9, in order to protect the product inside the packaging box, a first reinforcing region 111 is disposed in the middle of the bottom wall 110 of the packaging box; and/or, a second reinforcing area 121 is arranged in the middle of the side wall 120 of the packing box; the side wall 120 is provided with an inserting groove 122 communicated with the accommodating cavity; the package further comprises an accessory 300, the accessory 300 comprising: the plug part 310, the plug part 310 is plugged in the plug groove 122; the abutting portion 320, the abutting portion 320 is fixedly connected with the inserting portion 310 and is used for abutting against the product in the packing box.

Specifically, the utility model discloses among the technical scheme, seted up inserting groove 122 through the lateral wall 120 that holds the chamber at the packing box, the effect in the packing box was installed in annex 300 has been realized in inserting groove 122 to the grafting portion 310 of annex 300. Further, the accessory 300 further includes a supporting portion 320, and the supporting portion 320 is fixedly connected with the insertion portion 310 and abuts against the sidewall 120 of the display panel, so that a limiting effect of the accessory 300 on a product in the accommodating cavity is achieved.

By inserting or removing the accessory 300 into or from the slot 122, the accessory 300 can be recycled independently, thereby saving resources and reducing cost. In addition, the abutting portion 320 may be an abutting plate adapted to the height of the sidewall 120. Specifically, the accessory 300 includes two inserting plates arranged in a cross manner, the two inserting plates are arranged in a cross manner, the inserting groove 122 is in an "L" shape or a "cross" shape, two adjacent arm plates of the accessory 300 can be inserted into the inserting groove 122, the abutting portion 320 is formed by the other two arm plates of the accessory 300 and is abutted to the inner wall of the accommodating cavity respectively, one side of the abutting portion 320 of the accessory 300 facing the accommodating cavity can be further provided with a buffer block 330, the buffer block 330 is clamped between the abutting portion 320 and the product, the buffer block can be made of sponge, foam or rubber, and the like, the buffer block 330 can be adhered to the abutting portion 320 and can also be fixedly connected to the abutting portion 320 through a connecting piece, so that the buffer blocks 330 respectively connected to the two abutting portions 320 can buffer and protect the product in the accommodating cavity from two directions perpendicular to each other, it can be understood that, in this embodiment, when the packaging box is a cuboid, the insertion groove 122 can be arranged at the corner of the packing box, and the buffer accessory 300 can protect the corner of the product in the accommodating cavity when being arranged in the insertion groove 122, so that the product is prevented from being deformed or damaged due to the fact that the corner of the display panel generates large stress. In addition, the hardness of the buffering block 330 can be less than that of the supporting portion 320, so that the buffering block 330 has a better buffering effect on the product in the accommodating cavity.

As shown in fig. 5, in order to reduce the impact on the display panel, the sidewall 120 of the packing box may further be provided with a buffer slot 123, and the buffer slot 123 penetrates through the upper end surface of the sidewall 120.

The lateral wall 120 of packing box has the structure of cavity for the setting of dashpot 123 to can make external force have the space of taking place deformation because of the striking to the packing box, and then make partly striking energy transform elastic potential energy, play the buffering effect to impact, the vibration of external force promptly, reduce the impulse size to display panel, reduced the damage degree to display panel. It is understood that the size of the buffer slot 123 should not be too large, and the buffer slot 123 needs to be set on the basis that the strength of the packing box is not greatly affected.

Further, as shown in fig. 5, when the display panel is mounted on the packaging box, stress concentration is likely to occur in corners of the display panel when an impact is applied thereto. In this embodiment, the packing box is the cuboid, and adjacent lateral wall 120 encloses to close and is formed with the corner portion, and the dashpot 123 has been seted up to the corner portion.

The buffer grooves 123 are formed in the corner parts of the packaging box, so that the impact effect of the position, where stress concentration is most likely to occur, in the display panel can be reduced; on the other hand, the strength of the packing box is not greatly influenced. Specifically, the cross-sectional shape of the groove body of the buffer groove 123 may be any shape, and may be, for example, a circle, an arc, a rectangle, a triangle, or another irregular shape. Further, in order to prevent the side wall 120 of the buffer slot 123 from stress concentration and enhance the deformation resistance of the slot body of the buffer slot 123, thereby weakening the damage degree of the external impact force to the slot body of the buffer slot 123, the cross-sectional shape of the slot body of the buffer slot 123 may be selected as a circular arc.

Furthermore, during transport, the products and their packaging components that protect the products are often subject to falling. The product is susceptible to vertical impacts and the possibility of rollover. As shown in fig. 8, in order to protect the product inside the box body 100, an elastic member 400 is further embedded in the bottom wall 110 of the box body 100, thereby providing a cushioning effect to the product during transportation. Further, the elastic member 400 includes a first spring 410 extending vertically and a second spring 420 extending in an inclined manner with respect to the horizontal plane, the first spring 410 is fixedly connected to the middle of the bottom wall 110, and the second spring 420 is fixedly connected to the edge of the bottom wall 110.

Further, by fixedly connecting the first spring 410 to the middle of the buffer base and the second spring 420 to the edge of the buffer base, the first spring 410 can resist a part of the impact force in the vertical direction, and the second spring 420 can resist a part of the oblique impact force, so that the display panel can be buffered when falling in the vertical direction or falling from the side.

Further, referring to fig. 6 and 7, in order to protect the product inside the box body 100, the packing box further includes a box cover 200, and the box cover 200 covers the opening of the accommodating cavity.

It is understood that the box body 100 (bottom wall 110 or side wall 120) of the packing box is slidably connected, hinged or inserted with the box cover 200. When the box body 100 and the box cover 200 are slidably connected, one of the box cover 200 and the box body 100 may be provided with a sliding groove 125, and the other one may be provided with a sliding rail (not shown), and the sliding connection of the box cover 200 and the box body 100 is realized by inserting the sliding rail into the sliding groove 125. Specifically, the sliding direction of the case body 100 and the case lid 200 when sliding relative to each other may be along the horizontal direction or the vertical direction. In the process of sliding the box cover 200 to cover the opening of the box body 100, in order to prevent the user from pushing the box cover 200 out of the box body 100 due to excessive force, a stopping portion 1251 is disposed at one end of the sliding groove 125, and one end of the sliding rail can abut against the stopping portion 1251.
