Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a blister box for an electricity meter. Background Technology

[0002] Electricity meters on the market consist of multiple components, such as the casing, terminals, mainboard, and single-phase or three-phase meters, etc., with a relatively special structure. In particular, incomplete meter components, such as semi-finished products with terminals connected to single-phase or three-phase meters, need to be placed in packaging boxes or cartons for protection during transportation. However, due to the special structure of electricity meters, such as probes on the terminals, conventional packaging boxes cannot protect the probes and are easily damaged. Designing a special packaging box for special structures requires balancing cost and manufacturing process. Therefore, there is an urgent need for a packaging box that can protect the special structure of electricity meters and is easy to implement. Utility Model Content

[0003] The purpose of this utility model is to design a blister box for electricity meters to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs a blister box for an electricity meter, including a blister box cover and a packaging box body. The packaging box body has a cavity with the opening facing upwards. A partition structure is provided inside the cavity, which divides the cavity into multiple receiving cavities for placing electricity meter accessories. The blister box cover is formed by a top wall and four side walls with the opening facing downwards. The bottom surface of the top wall has several protrusions. When the blister box cover covers the packaging box body, the protrusions of the blister box cover abut against the surface of the electricity meter accessories and engage with the surface of the electricity meter accessories to form a limiting position.

[0005] Preferably, the meter accessories include a combination of terminals and a single-phase meter or a combination of terminals and a three-phase meter. The terminals have recesses and probes on their surface, and the single-phase meter or three-phase meter is connected to one side of the terminals. Further optimization involves the protrusion comprising a first protrusion and a second protrusion, wherein the first and second protrusions respectively abut against the recesses of the corresponding terminals and the top of the single-phase or three-phase meter. Further optimization involves the following: when the meter is a single-phase meter, each accommodating cavity contains two meter components, which are placed side-by-side facing each other with the two single-phase meters located in the middle. There are two first protrusions, which are positioned opposite each other and abut against the recesses of the corresponding terminals. There are also two second protrusions, which are located between the two first protrusions and abut against the top of the corresponding single-phase meter. The opposite sides of the second protrusions abut against the corresponding sides of the two terminals.

[0006] Further optimization involves placing a meter accessory inside each accommodating cavity when it is a three-phase meter. The wiring terminals are placed side by side with the three-phase meter facing each other. The first and second protrusions are also provided accordingly, with the first and second protrusions respectively abutting against the recess of the wiring terminal and the top of the three-phase meter.

[0007] Further optimization involves the first protrusion being a cuboid structure, with its top surface conforming to the shape of the bottom surface of the recess; and the second protrusion being a square structure, with its top surface abutting against or near the center of the surface of a single-phase or three-phase meter.

[0008] Further optimized, the partition structure includes a U-shaped plate, a horizontal plate, and a side plate. Several U-shaped plates are located inside the cavity of the packaging box and are arranged closely along the length of the packaging box. The long side of the previous U-shaped plate and the next U-shaped plate enclose a rectangular cavity, thereby dividing the cavity inside the packaging box into multiple cavities. The side plate is located at the side opening of the last U-shaped plate to enclose the last cavity. The long side of the U-shaped plate and the top center of the side plate are both provided with a first notch. The bottom of the horizontal plate is provided with multiple second notches along the length. The horizontal plate is inserted into the U-shaped plate by interlocking with the first and second notches. The horizontal plate divides each cavity into two parallel receiving cavities.

[0009] Further optimization involves using corrugated cardboard for both the packaging box body and the partition structure; and / or using transparent or semi-transparent plastic material for the blister box lid.

[0010] Further optimization involves providing a folded edge on the outer side of the sidewall, which is perpendicular or nearly perpendicular to the sidewall. When the blister box lid covers the packaging box, the folded edge of the blister box lid is located at or near the center of the packaging box in the height direction.

[0011] Further optimization involves the protrusion being formed by a downward indentation of the top wall of the blister box cover, with the top surface of the top wall being a horizontal plane.

[0012] The technical advantages of this invention are as follows: It includes a blister box cover and a packaging box. The packaging box contains a cavity separated by a partition structure. Two oppositely distributed meter accessories are placed within the cavity. After the blister box cover is placed on the packaging box, its top wall sinks to form a downwardly convex cavity, i.e., a protrusion. The protrusion includes a first protrusion and a second protrusion. The first protrusion abuts against the surface of the terminal block of the meter accessory. The surface of the terminal block has a recess, and the first protrusion and the recess form a convex-concave fit. The end of the second protrusion abuts against the surface of a single-phase or three-phase meter, thereby limiting the meter accessory within the cavity. Simultaneously, the probe of the terminal block is located on the top surface of the terminal block facing the single-phase or three-phase meter. Therefore, the probe is located between the first and second protrusions, preventing it from being compressed and bent. This not only ensures the stable placement of the meter accessory within the packaging box without displacement but also prevents the probe from being knocked askew. Furthermore, the blister box cover effectively prevents dust and has a transparent and aesthetically pleasing appearance. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] Example 1 The blister box for the electricity meter in this embodiment is used to hold the meter accessory 3. The meter accessory 3 includes a terminal block 31 and a single-phase meter 32. The terminal block 31 has a cuboid structure. The upper surface of the terminal block 31 has a rectangular recess 311. Several wiring terminals are provided in the recess 311. The single-phase meter 32 is connected to the front side of the terminal block 31. The upper surface of the single-phase meter 32 has a probe 33 near the front side. The probe 33 is vertically set relative to the upper surface. The single-phase meter 32 is not connected to the center of the front side of the terminal block 31, but is slightly offset to the side.

[0017] The blister box for the electricity meter includes a blister box cover 1 and a packaging box 2, which are arranged vertically. Both the blister box cover 1 and the packaging box 2 are box-shaped structures. The packaging box 2 has a cavity with its opening facing upwards. A partition structure 22 is provided inside the cavity, which divides the cavity into multiple receiving cavities 21. Electricity meter accessories 3 are placed in each receiving cavity 21, with two electricity meter accessories 3 placed in one receiving cavity 21. The blister box cover 1 is formed by a top wall 11 and four side walls 12, with its opening facing downwards. The bottom surface of the top wall 11 has several protrusions 14. Each protrusion 14 includes a first protrusion 141 and a second protrusion 142. There are two first protrusions 141, which are arranged opposite each other and abut against the rectangular recesses 311 of the corresponding terminals 31. There are two second protrusions 142, which are located between the two first protrusions 141. The protrusions 142 abut against the top of the corresponding single-phase meter 32. Since the two meter accessories 3 are placed opposite each other, the two single-phase meters 32 are placed side by side and staggered. The two opposite sides of the second protrusion 142 abut against the front sides of the two terminals 31 respectively. At this time, the two terminals 31 in the same accommodating cavity 21 are respectively located at the two ends of the accommodating cavity 21. Since the terminals 31 are cuboid in shape and the accommodating cavity 21 is also cuboid in shape, the terminals 31 and the ends of the accommodating cavity 21 form a limit. The end of the second protrusion 142 abuts against the upper surface of the single-phase meter 32, forming an upper and lower limit on the single-phase meter 32. Then, the two sides of the second protrusion 142 abut against the front sides of the two terminals 31 respectively, forming a certain limit on the terminals 31. The probe 33 is located in the space between the first protrusion 141 and the second protrusion 142, so it will not be pressed.

[0018] like Figure 6 As shown, from a top-down view, the dashed lines represent the first protrusion 141 and the second protrusion 142, which respectively abut against the recess 311 and the single-phase meter 32.

[0019] When the blister box cover 1 covers the packaging box 2, the first protrusion 141 and the second protrusion 142 of the blister box cover 1 abut against each surface of the meter accessory 3 and form a concave-convex fit with each surface of the meter accessory 3, thereby limiting the meter accessory 3 and ultimately allowing the two meter accessories 3 to be stably placed in the receiving cavity 21.

[0020] Furthermore, in this embodiment, the first protrusion 141 is a cuboid structure, and the top surface of the first protrusion 141 is adapted to the shape of the bottom surface of the recess 311. The recess 311 is a rectangular groove structure, so the bottom of the first protrusion 141 is also rectangular. The first protrusion 141 and the recess 311 form a concave-convex fit, thereby limiting the terminal 31. The shape of the single-phase meter 32 is close to a cube, and the contact end of the second protrusion 142 is also square. Of course, the second protrusion 142 can also be other square structures so that the contact end of the second protrusion 142 can abut against the surface of the single-phase meter 32, and the contact area is as large as possible. In this way, the second protrusion 142 will not easily deform. The top surface of the second protrusion 142 abuts against the center position or near the center position of the surface of the single-phase meter 32.

[0021] Furthermore, the protrusion 14 is formed by the downward recess of the top wall 11 of the blister box cover 1, and the top surface of the top wall 11 is a horizontal surface. That is, the protrusion 14 is similar to a recessed cavity structure, which not only has a mature manufacturing process and simple structure, but also facilitates stacking.

[0022] The partition structure 22 includes a U-shaped plate 221, a horizontal plate 222, and a side plate 223. In this embodiment, the U-shaped plate 221 is formed by bending both ends of the plate towards the same side. It includes a long side 2211 and end faces located at both ends of the long side 2211. There are four U-shaped plates 221. The four U-shaped plates 221 are located in the cavity of the packaging box 2 and are arranged closely along the length of the packaging box 2. The long side 2211 of the previous U-shaped plate 221 and the next U-shaped plate 221 enclose a rectangular cavity 224, thereby dividing the cavity inside the packaging box 2 into multiple cavities 224. The two end faces of the U-shaped plate 221 abut against the two opposite inner walls of the packaging box 2. The side plate 223 is located on the side of the last U-shaped plate 221. The opening is enclosed to form the last cavity 224. The long side 2211 of the first U-shaped plate 221 and the side plate 223 of the fourth U-shaped plate 221 both abut against the other two opposite inner walls of the packaging box 2. The long side 2211 of the U-shaped plate 221 and the side plate 223 both have a first notch 225 at the top center. The bottom of the horizontal plate 222 has multiple second notches 226 along the length direction. The first notch 225 and the second notch 226 are set one-to-one. The horizontal plate 222 is inserted into the U-shaped plate 221 by interlocking the first notch 225 and the second notch 226. The horizontal plate 222 divides each cavity 224 into two parallel receiving cavities 21. Therefore, the partition structure 22 is not only simple in structure, but also easy to disassemble and assemble, which is very convenient.

[0023] Furthermore, both the packaging box body 2 and the partition structure 22 are made of corrugated cardboard, which provides strong support and makes the structure more robust, preventing collapse and facilitating the placement of the meter accessories 3; the blister box lid 1 is made of transparent or semi-transparent plastic material, such as PVC, PS, PP, PET, etc. The blister box is transparent and beautiful, keeps dust-free for long-term storage, and is also waterproof.

[0024] Furthermore, the outer side of the side wall 12 is provided with a folded edge 13, which is perpendicular or nearly perpendicular to the side wall 12, making it convenient to manually pick up the blister box lid 1. When the blister box lid 1 covers the packaging box 2, the folded edge 13 of the blister box lid 1 is located at or near the center of the height direction of the packaging box 2. When the blister boxes of the electricity meter are stacked, if the edge of the blister box lid 1 is flush with the packaging box 2, it is inconvenient to touch the side of the packaging box 2, thus making it inconvenient to pick up the packaging box 2.

[0025] In addition, multiple blister packs of electricity meters can be stacked in the same packaging box. The packaging box 2 of the previous blister pack is placed on the blister box cover 1 of the next blister pack. Since the top surface of the blister box cover 1 is horizontal, the packaging box 2 can be directly stacked on the blister box cover 1 without damaging the blister box cover 1 or the electricity meter accessories 3. In addition, the folded edge 13 of each blister box cover 1 abuts against the inner wall of the packaging box, so that the electricity meter blister pack does not shift between the inner wall of the packaging box and the inner wall of the packaging box, while also making it easy to pick up.

[0026] Example 2 In this embodiment, the blister box for the electricity meter is used to hold the meter accessory 3. The meter accessory 3 includes a terminal block 31 and a three-phase meter 34. The terminal block 31 has a cuboid structure. The upper surface of the terminal block 31 has a rectangular recess 311. Several terminals are provided in the recess 311. The three-phase meter 34 is connected to the terminal block 31 and arranged in parallel. The upper surface of the three-phase meter 34 has a probe 33 near the terminal block 31. The probe 33 is vertically positioned relative to the upper surface. The three-phase meter 34 is not connected to the center of the front side of the terminal block 31, but is slightly offset to the side.

[0027] The blister box for the electricity meter includes a blister box cover 1 and a packaging box 2. The structure of the packaging box 2 is the same as in Embodiment 1. The basic structure of the blister box cover 1 is the same as in Embodiment 1, and will not be described in detail here. The difference from Embodiment 1 is that the number and distribution of the protrusions are different. In this embodiment, each accommodating cavity contains an electricity meter accessory 3, namely a wiring terminal 31 and a three-phase meter 34.

[0028] The first protrusion 141 abuts against the rectangular recess 311 of the corresponding terminal 31, and the second protrusion 142 abuts against the top of the corresponding three-phase meter 34. The three-phase meter 34 and the terminal 31 are placed side by side facing each other in the left-right direction, while the single-phase meter 32 and the terminal 31 in Embodiment 1 are distributed in the front-back direction. The left or right side of the second protrusion 142 abuts against the corresponding terminal 31. Since the terminal 31 has a cuboid structure and the receiving cavity 21 is also cuboid, the end of the terminal 31 and the receiving cavity 21 form a limit. The end of the second protrusion 142 abuts against the upper surface of the three-phase meter 34, forming an upper and lower limit for the three-phase meter 34. Then, one side of the second protrusion 142 abuts against the corresponding side of the terminal 31, forming a certain limit for the terminal 31. The probe 33 is located in the space between the first protrusion 141 and the second protrusion 142, so it will not be pressed.

[0029] like Figure 11 As shown, from a top-down view, the dashed lines represent the second protrusion 142 and the first protrusion 141, which respectively abut against the three-phase meter 34 and the pit 311 distributed on the left and right.

[0030] When the blister box cover 1 covers the packaging box 2, the first protrusion 141 and the second protrusion 142 of the blister box cover 1 abut against the corresponding surface of the meter accessory 3 and form a concave-convex fit with the surface, thereby limiting the meter accessory 3 and ultimately allowing the meter accessory 3 to be stably placed in the receiving cavity 21.

[0031] Furthermore, in this embodiment, the first protrusion 141 is a cuboid structure, and a shorter cuboid protrusion 143 extends from the center of the side facing the second protrusion 142. The top surface of the first protrusion 141 matches the bottom surface of the recess 311, which is a rectangular groove structure. Therefore, the bottom of the first protrusion 141 is also rectangular. The first protrusion 141 and the recess 311 form a convex-concave fit, thereby limiting the position of the terminal 31. The three-phase meter 34 is cuboid in shape, and the contact end of the second protrusion 142 is also rectangular. Of course, the second protrusion 142 can also be other square structures so that the contact end of the second protrusion 142 can contact... On the surface of the three-phase meter 34, the contact area should be as large as possible so that the second protrusion 142 will not easily deform. The top surface of the second protrusion 142 abuts against the center position or near the center position of the surface of the three-phase meter 34. The side of the second protrusion 142 facing the first protrusion 141 protrudes inward relative to the small protrusion 143 to form a small concave part 144. That is, the small concave part 144 is recessed from the bottom surface of the top wall 11. In other words, the small concave part 144 has a recessed structure relative to the second protrusion 142, so that the second protrusion 142 forms a U-shaped shape when viewed from above. The small concave part 144 is directly opposite the probe 33. One side of the small protrusion 143 and the small concave part 144 together surround and protect the probe 33.

[0032] Similarly, in this embodiment, the protrusion 14 is formed by the downward recess of the top wall 11 of the blister box cover 1, and the top surface of the top wall 11 is a horizontal surface. That is, the protrusion 14 is similar to a recessed cavity structure, which not only has a mature manufacturing process and simple structure, but is also convenient for stacking.

[0033] In this embodiment, multiple blister packs of electricity meters can be stacked and placed in the same packaging box, which is the same as in Embodiment 1, and will not be described in detail here.

[0034] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
