Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and specifically relates to a packaging box for electronic and electrical equipment. Background Technology

[0002] Electronic and electrical equipment, including distribution cabinets and racks, requires packaging and transportation after assembly at the manufacturer before reaching the site of use. Currently, the typical packaging method for electronic and electrical equipment is to place the equipment on a structurally strong pallet, and then attach a packaging box to the pallet. The packaging box provides protection, while the pallet supports the equipment and is compatible with transport equipment. The packaging box is usually pre-formed before being attached to the equipment. To accommodate the large size of electronic and electrical equipment, the packaging box is generally also large and difficult to lift. Therefore, this method of pre-forming the packaging box and then attaching it is time-consuming and labor-intensive. Utility Model Content

[0003] This utility model provides a packaging box for electronic power equipment, aiming to solve the problem of time-consuming and labor-intensive operation when packaging electronic power equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A packaging box for electronic power equipment is provided, comprising:

[0006] The box assembly has a first clamping groove formed on each side. The first clamping grooves on both sides are not connected to each other and their opening directions are set at an angle.

[0007] Multiple side panel boxes, the side edges of which are inserted and fixed in the first clamping groove, and two adjacent side panel boxes are spliced ​​together by the box splicing parts, so that the multiple side panel boxes are sequentially enclosed to form a box structure with openings on the top and bottom sides respectively.

[0008] A lid is placed over the upper opening of the box structure.

[0009] In one possible implementation, the housing assembly has a first splicing body and two first clamping bodies respectively connected to both sides of the first splicing body. The first clamping bodies on both sides are arranged at an angle, and each first clamping body forms a first clamping groove.

[0010] In some embodiments, a first weakening hole extending along its own long axis is formed within the first splicing body.

[0011] In some embodiments, the first weakening hole is a through hole that penetrates the first splicing body.

[0012] In some embodiments, the outer surface of the first splicing body is a convex arc surface, and there is a smooth transition between the outer surface of the first splicing body and the outer surface of the first clamping body.

[0013] In some embodiments, the inner surface of the first splicing body is a convex arc surface, and there is a smooth transition between the inner surface of the first splicing body and the inner surface of the first clamping body.

[0014] In one possible implementation, the box cover includes a cover plate and cover splicing components respectively disposed around the cover plate. The two sides of the cover splicing components respectively form second clamping grooves. The second clamping grooves on both sides are not connected to each other and are set at an angle. The upper edge of the side box panel and the side edge of the cover plate are respectively inserted and fixed in the corresponding second clamping grooves.

[0015] In some embodiments, the cover splicing component has a second splicing body and two second clamping bodies respectively connected to both sides of the second splicing body. The two second clamping bodies are arranged at an angle, and each second clamping body forms a second clamping groove.

[0016] In some embodiments, a second weakening hole extending along its own long axis is formed within the second splicing body.

[0017] In one possible implementation, the lid includes a lid body and reinforcing supports. The lid body is bent downwards around its four sides to form enclosing flanges, which surround the outer periphery of the top of the box structure. The reinforcing supports have a first support plate and a second support plate that are fixedly connected to each other and arranged at an angle. The first support plate is attached to the upper surface of the lid body, and the second support plate is attached to the outer side of the enclosing flange.

[0018] Compared with the prior art, the solution shown in this application involves the following steps during packaging: First, the electronic power equipment is placed on a pallet. Then, one side panel is placed on one side of the electronic power equipment on the pallet. The box assembly is then secured to the side edge of the side panel through the first clamping slot. Next, the next side panel is placed on the pallet and secured to the other first clamping slot of the box assembly. This process is repeated until all the side panels surround and install the electronic power equipment. Adjacent side panels are assembled and fixed together with the box assembly to form a box structure with openings on both the top and bottom sides. Finally, the box lid is placed on the top opening of the box structure, and the packaging is complete. The electronic power equipment packaging box of this application is formed around the electronic power equipment on a pallet. During the forming process, the packaging box is gradually fastened to the outer periphery of the electronic power equipment. The packaging box does not need to be formed as a whole before being fastened to the electronic power equipment, which eliminates the problem of difficulty in lifting the packaging box. Furthermore, the forming steps and fastening operations of the packaging box are integrated, making the operation more labor-saving and efficient. In addition, since the first clamping groove is an open groove on one side and closed on the other side, it can effectively limit the insertion depth of the side panel when it is inserted, ensuring that the insertion depth between the box splicing parts and each side panel is consistent. This ensures that the assembled packaging box has a neater and smoother shape and provides better protection. Attached Figure Description

[0034] In the claims, description, and accompanying drawings of this utility model, the term "inner" refers to the direction toward the inner cavity of the box structure, and the term "outer" refers to the direction away from the inner cavity of the box structure. Other directional terms, unless otherwise explicitly defined, such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "upper," "lower," "front," "rear," "left," "right," "clockwise," "counterclockwise," "high," and "low," are used to indicate orientation or positional relationships based on the orientation and positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the specific scope of protection of this utility model.

[0035] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this utility model shall be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or components.

[0036] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0037] Please refer to the following: Figures 1 to 3 , Figures 6 to 8 The electronic power equipment packaging box provided by this utility model will now be described. The electronic power equipment packaging box includes a box body splicing component 1, side panels 2, and a box lid 3; first clamping grooves 101 are formed on both sides of the box body splicing component 1, the first clamping grooves 101 on both sides are not interconnected, and their opening directions are at an angle. (like Figure 3 As shown, the dashed arrow indicates the opening direction of the first clamping groove 101; multiple side panels 2 are provided, and the side edges of the multiple side panels 2 are inserted and fixed in the first clamping groove 101. Adjacent two side panels 2 are spliced ​​together by the box splicing piece 1, and the multiple side panels 2 are sequentially enclosed to form a box structure with openings on the upper and lower sides respectively; the box cover 3 is placed on the upper opening of the box structure.

[0038] In this embodiment, the enclosure structure is generally conforming to the outer contour of the electronic power equipment. The number of side panels 2 is consistent with the number of outer wall surfaces of the electronic power equipment, and they correspond one-to-one. The included angle between two adjacent side panels 2 is the same as the included angle between the opening directions of the two first clamping grooves 101 in the corresponding enclosure splice 1, and this included angle is affected by the number of side panels 2. This embodiment adaptively shows an example in which there are four side panels 2, and the included angle between the opening directions of the two first clamping grooves 101 in the same enclosure splice 1 is 90°. The number of side panels 2 can also be set to five, six, etc., which will not be listed here.

[0039] In this embodiment, the first clamping groove 101 is a through groove extending vertically, ensuring that the upper end of the side panel clamping member does not protrude beyond the upper edge of the side panel 2, and the lower end does not protrude beyond the lower edge of the side panel 2, thus avoiding affecting the fit between the side panel 2 and the tray and lid 3. The through groove design can also provide various installation methods. For example, the side edge of the side panel 2 can be aligned with a through port of the first clamping groove 101, and then gradually slid in along the extension direction of the first clamping groove 101; or, the edge of the side panel 2 can be aligned with the side opening of the first clamping groove 101 and directly inserted, and then the relative position of the box splicing member 1 and the side panel 2 can be slightly adjusted.

[0040] In this embodiment, both the side panel 2 and the lid 3 can be made of corrugated cardboard, which ensures both structural strength and lightweight and easy assembly / disassembly. Of course, the side panel 2 and the lid 3 can also be made of other materials, and this is not a limitation. The container assembly 1 can be made of plastic, obtained through extrusion molding.

[0041] Compared with the prior art, the packaging box for electronic power equipment provided in this embodiment first places the electronic power equipment on a pallet, places one side panel on one side of the electronic power equipment on the pallet, and then snaps the box body splicing piece 1 onto the side edge of the side panel through the first clamping groove 101. After the edge of the side panel contacts the closed side of the first clamping groove 101, the snapping is complete. Then, the next side panel is placed on the pallet and snapped into the other first clamping groove 101 of the box body splicing piece 1. The above process is repeated until all the side panels 2 are installed around the electronic power equipment. Adjacent side panels 2 are assembled and fixed together by the box body splicing piece 1 to form a box structure with openings on the top and bottom sides. Finally, the box lid 3 is placed on the top opening of the box structure, and the packaging is complete. In this embodiment, the electronic power equipment packaging box is formed around the electronic power equipment on a pallet. During the forming process, the packaging box is gradually fastened to the outer periphery of the electronic power equipment. The packaging box does not need to be formed as a whole before being fastened to the electronic power equipment, which avoids the problem of difficulty in lifting the packaging box. Furthermore, the forming steps and fastening operations of the packaging box are integrated, making the operation more labor-saving and efficient. In addition, since the first clamping groove 101 is a groove with one side open and the other side closed, it can effectively limit the insertion depth of the side panel 2 when it is inserted, ensuring that the insertion depth between the box splicing component 1 and each side panel 2 is consistent. This ensures that the assembled packaging box has a neater and smoother shape and provides better protection.

[0042] In some distribution patterns of the box assembly 1, see Figure 1 , Figure 6 and Figure 7Only one box-body splicing component 1 is provided between two adjacent side panel 2. In this case, in order to ensure the reliability of the splicing, the box-body splicing component 1 is a strip-shaped component continuously distributed in the vertical direction. Optionally, the lower end face of the box-body splicing component 1 is basically flush with the lower edge of the side panel 2, and the upper end face of the box-body splicing component 1 is basically flush with the upper edge of the side panel 2.

[0043] In other distribution configurations of the box assembly components 1 (not shown in the figure), multiple box assembly components 1 distributed vertically are arranged between two adjacent side panels 2. In this case, each box assembly component 1 is relatively short, facilitating manufacturing and transportation. Optionally, the lower end face of the bottommost box assembly component 1 is basically flush with the lower edge of the side panel 2, and the uppermost box assembly component 1 is basically flush with the upper edge of the side panel 2.

[0044] In some embodiments, see Figure 2 , Figure 3 and Figure 8 The box assembly 1 has a first splicing body 110 and first clamping bodies 120 respectively connected to both sides of the first splicing body 110. The first clamping bodies 120 on both sides are set at an angle (this angle is the aforementioned angle). Each first clamping body 120 forms a first clamping groove 101. The first clamping body 120 can be arranged to follow the surface direction of the side panel 2. The first splicing body 110 connects two first clamping bodies 120, thereby making the box splicing component 1 have integrity. Furthermore, the box splicing component 1 presents a structure with the same trend as the connection area of ​​the two adjacent side panels 2, avoiding occupying the internal space of the box structure, and making the box structure more compact and fit the electronic power equipment.

[0045] In some embodiments, the insertion and fixing method between the first clamping groove 101 and the side panel 2 is exemplified as follows:

[0046] 1) The two side walls of the first clamping groove 101 are smooth surfaces, and the two side walls are in close contact with the inner and outer sides of the edge of the side panel 2, respectively. The side panel 2 is clamped and fixed by interference clamping. The interference clamping method makes the connection between the side panel 2 and the first clamping body 120 simpler, and reasonably controls the distance between the first clamping groove 101 and the two side walls in the free state, which can ensure that the side panel 2 can be smoothly inserted and that the fixation is reliable.

[0047] 2) One sidewall of the first clamping groove 101 is provided with a snap-fit ​​protrusion, while the other sidewall is smoothly formed. The distance between the free end face of the snap-fit ​​protrusion and the opposite sidewall is less than the thickness of the side panel 2. The side panel 2 is provided with a snap-fit ​​slot corresponding to the snap-fit ​​protrusion. After the side panel 2 is inserted into the first clamping groove 101, the snap-fit ​​protrusion snaps into the corresponding snap-fit ​​slot, and the other side surface of the side panel 2 fits against the smoothly formed sidewall surface. Through the cooperation of the snap-fit ​​protrusion and the snap-fit, the side panel 2 can be effectively fixed even when the assembly stress on the side panel 2 is small, preventing the side panel 2 from coming out of the first clamping groove 101.

[0048] 3) The two side walls of the first clamping groove 101 are respectively provided with snap-fit ​​protrusions. The distance between the free end face of the snap-fit ​​protrusion and the opposite side wall is less than the thickness of the side panel 2. The side panel 2 is provided with slots corresponding to the snap-fit ​​protrusions. After the side panel 2 is inserted into the first clamping groove 101, the snap-fit ​​protrusions on both sides are respectively engaged in the corresponding slots. More specifically, in the vertical direction, the snap-fit ​​protrusions on the two side walls are staggered vertically.

[0049] Specifically, the first clamping body 120 includes two first clamping plates 121 that are respectively connected to the first splicing body 110. A first clamping groove 101 is formed between the two first clamping plates 121, and the opposite sides of the first clamping plates 121 are the side walls of the first clamping groove 101.

[0050] Based on the above embodiments, see Figure 2 , Figure 3 and Figure 8 The first splicing body 110 has a first weakening hole 102 extending along its own long axis. By setting the first weakening hole 102, the structural strength of the first splicing body 110 is reduced to a certain extent, so that the box splicing component 1 has a certain degree of flexibility, avoiding breakage during transportation, and making it easier for operators to assemble with the side box panel 2.

[0051] Optionally, for ease of manufacturing and to maximize the weakening effect, the first weakening hole 102 is a through hole that penetrates the first splicing body 110.

[0052] Based on the first splicing body 110 and two first clamping bodies 120 of the box splicing component 1, see Figure 2 , Figure 3 and Figure 8The outer surface of the first splicing body 110 is a convex arc surface, and there is a smooth transition between the outer surface of the first splicing body 110 and the outer surface of the first clamping body 120. The first splicing body 110 forms the edge of the side of the packaging box, which is arc-shaped to reduce the sharp corners of the packaging box and prevent scratches to operators when gripping or touching the packaging box. At the same time, the smooth transition between the first splicing body 110 and the first clamping body 120 also makes the outer surface of the box splice 1 smoother, avoiding stress concentration at the protruding edge that could cause the box splice 1 to crack, and extending the service life of the box splice 1.

[0053] More specifically, in order to minimize the dead corners and sharp edges of the box splicing parts 1, the inner side of the first splicing body 110 is a convex arc surface, and the inner side of the first splicing body 110 and the inner side of the first clamping body 120 are smoothly transitioned.

[0054] In some embodiments, the aforementioned cover 3 may be adopted as follows: Figure 1 , Figures 4 to 7 , Figure 9 The structure shown includes a cover plate 310 and cover body splicing parts 320 respectively disposed around the cover plate 310. Second clamping grooves 3201 are formed on both sides of the cover body splicing parts 320. The second clamping grooves 3201 on both sides are not connected to each other, and their opening directions form an angle. (like Figure 5 As shown in the diagram (where the dashed arrow indicates the opening direction of the second clamping groove 3201), the upper edge of the side panel 2 and the side edge of the cover 310 are respectively inserted and fixed in the corresponding second clamping groove 3201. The use of the cover splicing component 320 in this embodiment is similar to that of the box splicing component 1, and will not be repeated here. Furthermore, the cover splicing component 320 can be made of plastic and obtained through extrusion molding. By using the cover splicing component 320 to achieve relative fixation between the cover 310 and the side panel 2, the position of the cover 3 relative to the box structure is very stable during transportation. Even without additional fixing components, the cover 3 is not easily detached, resulting in better reliability.

[0055] In some specific embodiments of the cover splice 320, see Figure 4 and Figure 5 The cover splicing component 320 has a second splicing body 321 and two second clamping bodies 322 respectively connected to both sides of the second splicing body 321. The two second clamping bodies 322 are set at an angle (this angle is the aforementioned angle). Each second clamping body 322 forms a second clamping groove 3201. The second clamping body 322 can be arranged to conform to the surface orientation of the side panel 2 and the cover 310. The second splicing body 321 connects the two first clamping bodies 120, thereby making the cover splicing component 320 have integrity. Furthermore, the cover splicing component 320 as a whole presents a structure with the same orientation as the connection area of ​​the adjacent side panel 2 and the cover 310, avoiding occupying the internal space of the packaging box, making the structure of the box cover 3 more compact and fit the electronic and electrical equipment.

[0056] Based on the above embodiments, see Figure 4 , Figure 5 and Figure 9 The second splicing body 321 has a second weakening hole 3202 extending along its long axis. By setting the second weakening hole 3202, the structural strength of the second splicing body 321 is reduced to a certain extent, giving the cover splicing component 320 a certain degree of flexibility, preventing breakage during transportation, and making it easier for operators to assemble it with the side panel 2 and the cover. Optionally, to facilitate manufacturing and maximize the weakening effect, the second weakening hole 3202 is a through hole penetrating the second splicing body 321.

[0057] In some specific embodiments, see Figure 4 , Figure 5 and Figure 9 The outer surface of the second splicing body 321 is a convex arc surface, and there is a smooth transition between the outer surface of the second splicing body 321 and the outer surface of the second clamping body 322. The second splicing body 321 forms the edge of the top of the packaging box, and its arc surface reduces the sharp corners of the packaging box and prevents operators from being scratched when gripping or touching the packaging box. At the same time, the smooth transition between the second splicing body 321 and the second clamping body 322 also makes the outer surface of the cover splice 320 smoother, avoiding stress concentration at the protruding edge that could cause the cover splice 320 to crack, thus extending the service life of the cover splice 320.

[0058] Furthermore, in order to minimize the dead corners and sharp edges of the box splicing parts 1, the inner side of the second splicing body 321 is a convex arc surface, and there is a smooth transition between the inner side of the second splicing body 321 and the inner side of the second clamping body 322.

[0059] In some distribution patterns of cover splicing components 320, see Figure 1 , Figure 6 and Figure 7Only one cover splice 320 is provided between the cover plate 310 and the adjacent side panel 2. In this case, in order to ensure the reliability of the splicing, the box splice 1 is a strip-shaped component continuously distributed in the horizontal direction. In order to avoid interference with the box splice 1, the length of the cover splice 320 is not greater than the distance between two adjacent box splice 1s. After assembly, the distance between the end face of the cover splice 320 and the side edge of the adjacent first splicing body 110 is 0~1mm, which does not affect the assembly and can also improve the reinforcement of the upper area of ​​the box structure by reducing the gap.

[0060] In some other distributions of the cover assembly 320 (not shown in the figure), multiple cover assembly 320s distributed horizontally are provided between the cover plate 310 and the adjacent side panel 2. In this case, the length of each cover assembly 320 is relatively short, which facilitates manufacturing and transportation.

[0061] In some embodiments, the insertion and fixing method between the second clamping groove 3201 and the side panel 2 and the cover plate 310 is exemplified as follows:

[0062] 1) The two side walls of the second clamping groove 3201 are smooth surfaces. The two side walls of one second clamping groove 3201 are in close contact with the inner and outer surfaces of the edge of the side panel 2, respectively. The two side walls of the other second clamping groove 3201 are in close contact with the upper and lower surfaces of the edge of the cover plate 310, respectively. The side panel 2 and the cover plate 310 are clamped and fixed by interference clamping. The interference clamping method makes the connection between the side panel 2 and the cover plate 310 and the second clamping body 322 simpler. By reasonably controlling the distance between the second clamping groove 3201 and the two side walls in the free state, it is possible to ensure that the side panel 2 and the cover plate 310 can be smoothly inserted and that the fixation is reliable.

[0063] 2) At least one sidewall of the second clamping groove 3201 is provided with a snap-fit ​​protrusion. The distance between the free end face of the snap-fit ​​protrusion and the opposite sidewall is less than the thickness of the side panel 2. The side panel 2 and the cover plate 310 are respectively provided with slots corresponding to the snap-fit ​​protrusions. After the side panel 2 or the cover plate 310 is inserted into the second clamping groove 3201, the snap-fit ​​protrusions on both sides are respectively engaged in the corresponding slots. Through the cooperation of the snap-fit ​​protrusions and the buckles, the side panel 2 and the cover plate 310 can be effectively fixed even when the assembly stress on the side panel 2 is small, preventing the side panel 2 or the cover plate 310 from coming out of the second clamping groove 3201.

[0064] Specifically, the second clamping body 322 includes two second clamping plates 3221 that are respectively connected to the second splicing body 321. A second clamping groove 3201 is formed between the two second clamping plates 3221, and the opposite sides of the second clamping plates 3221 are the side walls of the second clamping groove 3201.

[0065] In other embodiments, the aforementioned box cover 3 can be adopted as follows: Figure 10 and Figure 11 As shown in the diagram, the lid 3 includes a lid body 330 and reinforcing supports 340. The lid body 330 is bent downwards around its four sides to form enclosing flanges 350, which surround the outer perimeter of the top of the box structure. The reinforcing supports 340 have a first support plate 341 and a second support plate 342 that are fixedly connected to each other at an angle. The first support plate 341 is attached to the upper surface of the lid body 330, and the second support plate 342 is attached to the outer side of the enclosing flanges 350. The connection between the lid body 330 and the enclosing flanges 350 can be made by means including, but not limited to, integral bending connection or bonding with tape. The reinforcing supports 340 are made of materials including, but not limited to, plastic and metal. The first support plate 341 and the second support plate 342 are integrally formed by extrusion, casting, or other methods. In this embodiment, the cover body 330 and the surrounding flange 350 cooperate to form a snap-on structure. This snap-on structure can be directly snapped onto the upper part of the box structure. The surrounding flange 350 can provide cover. By setting the reinforcing support 340, the connection between the cover body 330 and the surrounding flange 350 is strengthened, avoiding deformation of the snap-on structure and improving the reliability of use.

[0066] In some specific embodiments of the enclosing flange 350, the enclosing flange 350 includes a first flange 351 and a second flange 352, which are alternately arranged along the circumference of the cover body 330.
