[0055] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0056] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0059] This utility model provides a packaging box for packaging an electronic balance 6. For example... Figure 1 , 2 As shown, the packaging box includes a base plate 1, a left side plate 21, and a right side plate 22. The top of the base plate 1 has a receiving cavity, the shape of which is adapted to the bottom contour of the electronic balance 6 to be packaged, facilitating stable placement of the electronic balance 6. This embodiment uses the electronic balance 6 as an example, but it is not limited to this and can also be applied to other structural devices.

[0060] The left side plate 21 and the right side plate 22 are arranged opposite each other and are detachably installed on the base plate 1. The two side plates 2 and the base plate 1 together form a complete packaging space 11, which completely encloses the entire electronic balance 6.

[0061] To facilitate the assembly of the base plate 1 and side plate 2 by operators, a guide positioning structure is provided between the base plate 1 and the side plate 2. This guide positioning structure can guide the side plate 2 to move relative to the base plate 1 and position it at a designated location, ensuring that the side plate 2 can be accurately and quickly installed into place.

[0062] Specifically, see Figure 3The guiding and positioning structure includes a guide groove 101 disposed on the base plate 1 and guide posts 201 disposed on at least one side plate 2. Specifically, a guide groove 101 extending along the length of the side edge is disposed on each of the two sides of the base plate 1, and the cross-section of the guide groove 101 can be trapezoidal or wedge-shaped. Correspondingly, a guide post 201 that mates with the guide groove 101 is disposed at the bottom of the left side plate 21 and the right side plate 22, and the cross-sectional shape of the guide post 201 matches that of the guide groove 101, also adopting a trapezoidal or wedge-shaped design.

[0063] During actual assembly, the operator aligns the guide post 201 on the side plate 2 with the guide groove 101 on the base plate 1, and then lowers the side plate 2 vertically. Through the cooperation of the guide post 201 and the guide groove 101, the side plate 2 can move vertically to a preset position. This design of the guide groove 101 and guide post 201 ensures that even if there is an initial positional deviation, it can be automatically corrected during assembly, achieving precise positioning.

[0064] It should be noted that in other embodiments of this utility model, the positions of the guide groove 101 and the guide post 201 can be interchanged, that is, the guide groove 101 can be set on the side plate 2, and the guide post 201 can be set on the bottom plate 1, which is also within the scope of protection of this application.

[0065] Through the cooperative design of the guide groove 101 and the guide post 201, the quick and accurate assembly between the side plate 2 and the bottom plate 1 is realized, which effectively solves the problem of repeated adjustment of alignment required by traditional packaging, significantly improves packaging efficiency, and avoids product damage caused by improper assembly.

[0066] See Figure 3 , 4 The guide positioning structure adds a positioning groove 102 and a positioning post 202 to the original guide groove 101 and guide post 201. Specifically, a positioning groove 102 is provided at the end of the guide groove 101 and communicates with it. The depth of the positioning groove 102 is greater than that of the guide groove 101, forming a stepped structure. Correspondingly, a positioning post 202 protruding outward is provided at the end of the guide post 201. The size of the positioning post 202 is adapted to the positioning groove 102.

[0067] During assembly, as the operator moves the side plate 2 downwards along the guide groove 101, it is initially guided by the guide post 201 within the guide groove 101. As the side plate 2 approaches its final installation position, the positioning post 202, located at the end of the guide post 201, begins to enter the area of ​​the positioning groove 102. Due to the greater depth and specific contour of the positioning groove 102, tactile feedback is generated when the positioning post 202 falls into the positioning groove 102, indicating that the assembly is in place.

[0068] The engagement of the positioning groove 102 and the positioning post 202 forms a reliable two-stage positioning mechanism. The inner wall of the positioning groove 102 and the outer surface of the positioning post 202 can, at least partially, employ an interference fit or a transition fit to generate a certain amount of friction, ensuring that the side plate 2 will not loosen or detach due to slight external forces after assembly. This design effectively prevents the side plate 2 from shifting during transportation.

[0069] It should be noted that the positions of the positioning groove 102 and the positioning post 202 can correspond to the positions of the guide groove 101 and the guide post 201. When the guide groove 101 is set on the base plate 1, the positioning groove 102 is also set on the base plate 1 accordingly; when the guide groove 101 is set on the side plate 2, the positioning groove 102 is also set on the side plate 2 accordingly. This symmetrical design ensures the effective coordination of the positioning function and the guiding function.

[0070] By adding a positioning groove 102 and a positioning post 202 to the cooperative structure, this utility model not only ensures rapid assembly, but also further improves positioning accuracy and connection reliability, effectively solving the problem of loose parts that may occur during transportation of traditional packaging boxes, and providing a safer protective environment for the products inside.

[0071] In other embodiments, the positioning groove 102 and the positioning post 202 may also be set at other positions on the base plate 1 and the side plate 2, as long as they can play a positioning and guiding role, which is also within the protection scope of this application.

[0072] See Figure 3 , 4 The positioning post 202 is directly disposed at the end of the guide post 201, forming an integral structure with the guide post 201. Correspondingly, the positioning groove 102 is disposed at the end of the guide groove 101 and remains in communication with the guide groove 101. The depth of the positioning groove 102 is greater than the depth of the guide groove 101, and its contour precisely matches the shape of the positioning post 202. This continuous groove design ensures the continuity and smoothness from guiding to positioning, avoiding jamming during the assembly process.

[0073] Specifically, a guide ramp is provided at the entrance of the positioning groove 102, which cooperates with the end ramp of the positioning post 202 to guide the positioning post 202 smoothly into the positioning groove 102. Even in the event of a slight misalignment, this ramp structure can automatically correct the position to ensure that the positioning post 202 falls accurately into the positioning groove 102.

[0074] The positioning pin 202 and the positioning groove 102 adopt a transition fit or a small clearance fit, which ensures both smooth assembly and a certain degree of reliability after positioning. When the positioning pin 202 is fully inserted into the positioning groove 102, the horizontal displacement of the side plate 2 is completely restricted due to the constraint of the mating surface.

[0075] See Figure 5 At least one limiting block 203 is provided on the right side of the left side plate 21. The limiting block 203 has a wedge-shaped or trapezoidal structure, and preferably has a guide slope. Correspondingly, a limiting groove 204 is provided on the left side of the right side plate 22 at a corresponding position. The shape of the limiting groove 204 is adapted to the limiting block 203. Similarly, in a preferred embodiment, it has a mating slope.

[0076] When the two side plates 2 close together, the limiting block 203 can quickly and accurately slide into the limiting groove 204, completing the lateral connection between the two side plates 2. When the two side plates 2 are respectively provided with guide slopes and mating slopes, the guide slope of the limiting block 203 first contacts the mating slope of the limiting groove 204. As the two side plates 2 continue to close together, under the guidance of the slopes, the limiting block 203 can automatically slide into the limiting groove 204. This slope mating design makes the assembly process smooth and natural, achieving accurate positioning without applying excessive force.

[0077] The limiting structure forms a reliable connection between the two side plates 2. When the packaging box is subjected to external impact or vibration, the mating surfaces of the limiting block 203 and the limiting groove 204 can effectively resist lateral forces and prevent relative displacement of the two side plates 2, thereby maintaining the overall stability of the packaging box.

[0078] It should be noted that the positions of the limiting block 203 and the limiting groove 204 can be interchanged. That is, the limiting groove 204 can be set on the left side plate 21, and the limiting block 203 can be set on the right side plate 22, achieving the same technical effect. In addition, the number of limiting structures can be adjusted according to the size of the packaging box and the load-bearing requirements.

[0079] By setting a limiting structure, this utility model further enhances the lateral connection between the side plates 2 on the basis of the vertical positioning of the bottom plate 1 and the side plates 2, forming a three-dimensional positioning protection network, which improves the assembly speed and convenience, while enhancing the overall stability of the packaging box during transportation.

[0080] In another embodiment, the limiting block 203 and the limiting groove 204 can also be replaced with a buckle and a groove, making the connection between the two side plates more stable.

[0081] See Figure 2 Multiple evenly distributed cushioning structures are provided on the lower surface of the base plate 1 and / or the outer surface of the side plate 2. These cushioning structures can absorb impact energy from the outside. When the packaging box is subjected to vertical vibration or drop, the cushioning structures effectively reduce the impact force transmitted to the internal products through their own elastic deformation, providing all-round protection for the internal precision electronic balance 6.

[0082] Specifically, the buffer structure includes lower buffer pillars 51, upper buffer pillars 52, front buffer pillars 53, rear buffer pillars 54, and side buffer pillars 55. Lower buffer pillars 51 are arranged in a matrix on the lower surface of the base plate 1. When the packaging box is placed on the transport surface, these lower buffer pillars 51 together form the first-level buffer barrier, dispersing the load through evenly distributed support points and effectively absorbing impact energy from the bottom.

[0083] Multiple upper buffer pillars 52 are provided on the top wall 26 of the side panel 2. When multiple packaging boxes are stacked, these upper buffer pillars 52 can effectively relieve the pressure transmitted by the upper packaging boxes.

[0084] Multiple front buffer posts 53 are provided on the front wall 24 of the side panel 2, and two rear buffer posts 54 are provided on the rear wall 25 of the side panel 2. The front buffer posts 53 and the rear buffer posts 54 are mainly designed to cope with accidental frontal and rearward collisions of the packaging box, and absorb impact energy through gradual deformation.

[0085] Multiple side buffer posts 55 are provided on the side wall 23 of the side panel 2. The side buffer posts 55 mainly provide lateral buffer protection and effectively resist lateral impacts during transportation.

[0086] With this comprehensive cushioning configuration, the packaging box of this invention establishes a three-dimensional cushioning protection system, ensuring the safety of the internal precision instruments in complex transportation environments.

[0087] It should be noted that the number, size, and arrangement of the buffer columns in each part can be adjusted according to specific packaging requirements, and these adjustments and improvements based on the same concept should be included within the protection scope of this utility model.

[0088] See Figure 2 , 6 On the inner walls of the left side plate 21 and the right side plate 22, there are inwardly protruding partitions 205. The partitions 205 are elongated wedge-shaped structures that extend inward along the inner walls of the side plates 2. After the side plates 2 are installed in place, the partitions 205 are positioned precisely in the structural gap between the instrument part 61 and the weighing body part 62 of the electronic balance 6.

[0089] During the assembly process, when the side plate 2 slides down to the working position along the guide positioning structure, the partition 205 is simultaneously inserted into the gap between the instrument part 61 and the scale body part 62.

[0090] By providing the divider 205, the packaging space 11 is effectively divided into two areas, namely the first space 111 and the second space 112, where the instrument part 61 and the weighing body part 62 are respectively installed. This separation design achieves multiple protective effects: firstly, it prevents the instrument part 61 and the weighing body part 62 from colliding with each other during transportation; secondly, the support provided by the divider 205 enhances the stability of the product within the packaging box; and finally, the elasticity of the divider 205 provides additional cushioning protection.

[0091] It should be noted that the specific shape of the partition 205 is not limited to a wedge shape, but can also be a trapezoid, rectangle or other geometric shapes; the number of partitions 205 can be adjusted according to the needs of the product structure, and multiple partitions 205 can be set to form more independent spaces. These variations and improvements based on the same concept should be included within the protection scope of this utility model.

[0092] Optionally, a viewing window is provided on side panel 2 to facilitate observation of the product status inside the box. Optionally, installation indicator arrows are provided on the surface of side panel 2 to provide operators with intuitive assembly guidance.

[0093] The packaging box in this embodiment also includes fixing straps 3 wrapped around the outside of the base plate 1 and side plates 2, which can firmly fix the various structures together. By tightening the fixing straps 3, the overall stability of the packaging box during transportation is ensured. To facilitate the installation of the fixing straps 3, fixing platforms 4 are provided on both the base plate 1 and the side plates 2 in this embodiment. The fixing platforms 4 are provided with strap grooves 41. To facilitate the fixing straps 3 being accommodated in the strap grooves 41, the width of the strap grooves 41 is slightly larger than the width of the fixing straps 3. According to this design, the fixing straps 3 can be prevented from shifting or loosening during transportation, ensuring the overall stability of the packaging box.
