In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples.

In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.
[0041] The packaging structure 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0042] like Figure 1-Figure 13As shown, the packaging structure 100 according to the embodiment of the present invention comprises: a packaging body 1, the packaging body 1 has a first side surface 11 and a second side surface 12 that are opposite to each other along a first direction e1, and at least one of the first side surface 11 and the second side surface 12 is provided with a plurality of limiting blocks 2, and the plurality of limiting blocks 2 located on the same side constitute a plurality of groups of limiting structures for fixing the packaged article 200. Thus, the packaged article 200 can be effectively fixed by the plurality of limiting blocks 2 in the limiting structure, so as to reduce the shaking amplitude of the packaged article 200 during the transportation of the packaging structure 100, and the limiting structure constituted by the plurality of limiting blocks 2 has a good protective effect on the packaged article 200 placed therein, which is conducive to improving the safety of the packaged article 200 during the transportation.
[0043] It should be noted that, one of the first side 11 and the second side 12 may be provided with a plurality of limit blocks 2. For example, if the plurality of limit blocks 2 are all provided on the first side 11 or the plurality of limit blocks 2 are all provided on the second side 12, the difficulty of production and processing of the packaging structure 100 can be reduced. At the same time, the plurality of limit structures formed by the plurality of limit blocks 2 are located on the same side of the packaging structure 100 in the first direction e1, which is conducive to reducing the difficulty of placing the packaged items 200 into the limit structure or taking them out of the limit structure, and is conducive to improving the efficiency of taking and placing the packaged items 200. In addition, the side of the packaging structure 100 provided with the limit blocks 2 can be placed upward to reduce the risk of the packaged items 200 falling off the limit structure. Alternatively, the first side 11 and the second side 12 may be provided with a plurality of limit blocks 2, so that a plurality of limit structures can be formed on the first side 11 and the second side 12, thereby increasing the upper limit of the number of packaged items 200 that the packaging structure 100 can accommodate, which is conducive to saving the number of packaging structures 100 used and the use cost.
[0044] Among them, the plurality of groups of limiting structures at least include a first limiting structure 10 for fixing the packaged article 200 extending in a straight strip shape along the second direction e2 and a second limiting structure 20 for fixing the packaged article 200 extending in a curved shape along the second direction e2, and the second direction e2 is perpendicular to the first direction e1. In other words, it is possible to flexibly choose to fix it through the first limiting structure 10 or through the second limiting structure 20 according to the shape of the packaged article 200. Thus, the packaging structure 100 can accommodate a variety of packaged articles 200 of different shapes through the first limiting structure 10 and the second limiting structure 20, thereby better improving the versatility of the packaging structure 100, and at the same time, better reducing the number of models of the packaging structure 100 required to be produced to adapt to packaged articles 200 of different shapes, which is conducive to reducing the production and use costs of the packaging structure 100.
[0045] According to the packaging structure 100 of the embodiment of the present invention, a variety of packaged items 200 of different shapes can be accommodated through the first limiting structure 10 and the second limiting structure 20, so that the versatility of the packaging structure 100 can be greatly improved. At the same time, the number of models of the packaging structure 100 that need to be produced to suit packaged items 200 of different shapes can be greatly reduced, which is beneficial to reducing the production and use costs of the packaging structure 100.
[0046] According to some embodiments of the present invention, the side wall of the limiting block 2 in the third direction e3 is formed as a first limiting surface 21 suitable for contacting the packaged item 200, and the first limiting structure 10 and the second limiting structure 20 both include at least a plurality of first limiting surfaces 21 arranged along the second direction e2 and distributed on both sides of the packaged item 200 in the third direction e3, and the third direction e3 is perpendicular to the second direction e2 and perpendicular to the first direction e1.
[0047] That is to say, the first limiting structure 10 at least includes a plurality of first limiting surfaces 21 arranged along the second direction e2. After the packaged article 200 extending in a straight strip shape along the second direction e2 is placed in the first limiting structure 10, a portion of the plurality of first limiting surfaces 21 of the first limiting structure 10 is located on one side of the packaged article 200 in the third direction e3 and contacts the packaged article 200, and another portion of the plurality of first limiting surfaces 21 of the first limiting structure 10 is located on the other side of the packaged article 200 in the third direction e3 and contacts the packaged article 200. Therefore, the packaged article 200 in the third direction e3 is Both sides have parts that contact the first limiting surface 21 of the first limiting structure 10, that is, the first limiting surfaces 21 on both sides of the packaged article 200 can be used to clamp and fix the packaged article 200 in the third direction e3, so as to better prevent the packaged article 200 from shaking in the third direction e3 after being placed in the first limiting structure 10. At the same time, the contact area between the packaged article 200 and the first limiting structure 10 can be better increased to prevent stress concentration on the packaged article 200, which is beneficial to enhance the protective effect of the first limiting structure 10 on the packaged article 200 extending in a straight strip shape along the second direction e2.
[0048] In addition, the first limiting structure 10 can be flexibly adapted to various length specifications of straight strip-shaped packaged items 200 through the multiple first limiting surfaces 21, such as Fig. 9As shown, when a packaged item 200 in the shape of a straight strip is transported by the packaged item 200, the plurality of first limiting surfaces 21 arranged along the second direction e2 in the first limiting structure 10 can limit the packaged item 200 with a longer length together, and can also limit the packaged item 200 with a shorter length together through some of the first limiting surfaces 21 in the first limiting structure 10. For example, when the length of the packaged item 200 in the shape of a straight strip is longer, the packaged item 200 can contact all the first limiting surfaces 21 of the first limiting structure 10 after being placed in the third limiting structure; and when the length of the packaged item 200 in the shape of a straight strip is shorter, the packaged item 200 can contact only some of the first limiting surfaces 21 in the first limiting structure 10 after being placed in the first limiting structure 10. In this way, the versatility of the first limiting structure 10 can be well improved, which is conducive to reducing the production and use costs of the packaging structure 100.
[0049] The second limiting structure 20 at least includes a plurality of first limiting surfaces 21 arranged along the second direction e2. After the packaged article 200 extending in a curved shape along the second direction e2 is placed in the second limiting structure 20, a portion of the plurality of first limiting surfaces 21 of the second limiting structure 20 is located on one side of the packaged article 200 in the third direction e3 and contacts the packaged article 200, and another portion of the plurality of first limiting surfaces 21 of the second limiting structure 20 is located on the other side of the packaged article 200 in the third direction e3 and contacts the packaged article 200. Therefore, the packaged article 200 is located on both sides of the third direction e3. They all have a portion that contacts the second limiting surface 23 of the second limiting structure 20, that is, the second limiting surfaces 23 on both sides of the packaged article 200 can be used to clamp and fix the packaged article 200 in the third direction e3, thereby effectively preventing the packaged article 200 from shaking in the third direction e3 after being placed in the second limiting structure 20. At the same time, the contact area between the packaged article 200 and the first limiting structure 10 can be effectively increased to prevent stress concentration on the packaged article 200, which is beneficial to improving the protective effect of the second limiting structure 20 on the packaged article 200 extending in a straight strip shape along the second direction e2.
[0050] In addition, the plurality of first limiting surfaces 21 of the second limiting structure 20 can be flexibly adapted to various length specifications of the curved packaged articles 200, such as Fig. 9As shown, when the curved package 200 is transported by the package 200, the multiple first limiting surfaces 21 arranged along the second direction e2 in the second limiting structure 20 can jointly limit the package 200 with a longer length, and the package 200 with a shorter length can also be jointly limited by part of the first limiting surfaces 21 in the second limiting structure 20. If the length of the curved package 200 is longer, the package 200 can contact all the first limiting surfaces 21 of the second limiting structure 20 after being placed in the third limiting structure; if the length of the curved package 200 is shorter, the package 200 can only contact part of the first limiting surfaces 21 in the second limiting structure 20 after being placed in the second limiting structure 20. In this way, the versatility of the second limiting structure 20 can be well improved, which is conducive to reducing the production and use costs of the packaging structure 100.
[0051] According to some embodiments of the present invention, the plurality of first limiting surfaces 21 of the first limiting structure 10 are parallel to the second direction e2, so that after the packaged article 200 extending in a straight strip along the second direction e2 is placed in the first limiting structure 10, the first limiting surface 21 is parallel to the straight strip packaged article 200, so that the contact area between the first limiting surface 21 of the first limiting structure 10 and the straight strip packaged article 200 can be increased, so that the fixing effect of the first limiting structure 10 on the straight strip packaged article 200 can be improved, and stress concentration on the straight strip packaged article 200 can be avoided, which is conducive to improving the protective effect of the first limiting structure 10 on the straight strip packaged article 200. At least part of the plurality of first limiting surfaces 21 of the second limiting structure 20 has an angle with the second direction e2. That is to say, at least part of the multiple first limiting surfaces 21 in the second limiting structure 20 are inclined relative to the second direction e2, so that the first limiting surfaces 21 in the second limiting structure 20 that are inclined relative to the second direction e2 can better contact the curved part of the packaged article 200 extending in a curved shape along the second direction e2, that is, it is ensured that the second limiting structure 20 can better adapt to the curved packaged article 200, so that the contact area between the first limiting surface 21 of the second limiting structure 20 and the curved packaged article 200 can be better increased, so that the fixing effect of the first limiting structure 10 on the straight packaged article 200 can be enhanced, and stress concentration on the straight packaged article 200 can be avoided, which is beneficial to improving the protective effect of the first limiting structure 10 on the straight packaged article 200.
[0052] It should be noted that all the first limiting surfaces 21 in the second limiting structure 20 may have an angle with the second direction e2, or some of the first limiting surfaces 21 in the second limiting structure 20 may have an angle with the second direction e2, while another part may be parallel to the second direction e2, and so on. The specific shape of the first limiting surfaces 21 of the second limiting structure 20 can be flexibly adjusted according to the shape of the packaged item 200, and no specific restrictions are made here.
[0053] According to some embodiments of the present invention, the first limiting structure 10 and the second limiting structure 20 share a portion of the first limiting surface 21, and the first limiting surface 21 shared by the first limiting structure 10 and the second limiting structure 20 is parallel to the second direction e2. In other words, a portion of the first limiting surface 21 in the second limiting structure 20 is parallel to the second direction e2, and another portion of the first limiting surface 21 in the second limiting structure 20 has an angle with the second direction e2. The first limiting surface 21 shared by the first limiting structure 10 and the second limiting structure 20 can be used to limit the straight strip package 200 placed in the first limiting structure 10, and the first limiting surface 21 shared by the first limiting structure 10 and the second limiting structure 20 can also be used to limit the curved package 200 placed in the second limiting structure 20.
[0054] Therefore, the portion of the packaged article 200 extending in a straight strip shape along the second direction e2 that contacts the first limiting surface 21 shared by the first limiting structure 10 and the second limiting structure 20, and the portion of the packaged article 200 extending in a curved shape along the second direction e2 that contacts the first limiting surface 21 shared by the first limiting structure 10 and the second limiting structure 20 are located in the same area, that is, the limiting space for the straight-shaped packaged article 200 fixed by the first limiting structure 10 partially overlaps with the limiting space for the curved-shaped packaged article 200 fixed by the second limiting structure 20. In other words, the limiting spaces of the first limiting structure 10 and the second limiting structure 20 are located in the same area. The spaces include overlapping areas that overlap with each other and independent areas that are independent of each other, which can reduce the space occupied by the independent areas of the first limiting structure 10 and the independent areas of the second limiting structure 20 on the packaging structure 100. Therefore, when transporting straight-shaped packaged items 200, the independent areas of the second limiting structure 20 have little effect on the number of straight-shaped packaged items 200 contained in the packaging structure 100. At the same time, when transporting curved packaged items 200 through the packaging structure 100, the independent areas of the first limiting structure 10 have little effect on the number of curved packaged items 200 contained in the packaging structure 100. In this way, the versatility of the packaging structure 100 can be ensured while the upper limit of the number of packaged items 200 contained in the packaging structure 100 can be increased.
[0055] According to some embodiments of the present invention, two first limiting surfaces 21 facing each other in the third direction e3 constitute a first limiting surface group 22 for clamping the packaged item 200, and in the second direction e2, the first limiting structure 10 and the second limiting structure 20 both include at least a plurality of first limiting surface groups 22. That is, when the packaged item 200 is placed between the two first limiting surfaces 21 of the first limiting surface group 22, the two first limiting surfaces 21 are in contact with both sides of the packaged item 200 in the third direction e3, thereby clamping and fixing the portion of the packaged item 200 between the two first limiting surfaces 21, and the plurality of first limiting surface groups 22 can increase the clamping position of the first limiting structure 10 and the second limiting structure 20 on the packaged item 200, which is conducive to improving the fixing effect of the first limiting structure 10 and the second limiting structure 20.
[0056] According to some embodiments of the present invention, the plurality of groups of limiting structures further include a third limiting structure 30 for fixing the packaged article 200 extending in a straight strip shape along the third direction e3, the side wall of the limiting block 2 in the second direction e2 is a second limiting surface 23 suitable for contacting the packaged article 200, and the third limiting structure 30 includes a plurality of second limiting surfaces 23 arranged along the third direction e3 and distributed on both sides of the packaged article 200 in the second direction e2, and the third direction e3 is perpendicular to the second direction e2 and perpendicular to the first direction e1. That is, after the packaged article 200 extending in a straight strip shape along the third direction e3 is placed in the third limiting structure 30, a portion of the plurality of second limiting surfaces 23 of the third limiting structure 30 is located on one side of the packaged article 200 in the second direction e2 and contacts the packaged article 200, and another portion of the plurality of second limiting surfaces 23 of the third limiting structure 30 is located on the other side of the packaged article 200 in the second direction e2 and contacts the packaged article 200. Therefore, both sides of the packaged article 200 in the second direction e2 have parts that are in contact with the second limiting surface 23, that is, the second limiting surfaces 23 on both sides of the packaged article 200 can be used to clamp and fix the packaged article 200 in the second direction e2, thereby effectively preventing the packaged article 200 from shaking in the second direction e2 after being placed in the third limiting structure 30. At the same time, the contact area between the packaged article 200 and the third limiting structure 30 can be effectively increased to prevent stress concentration on the packaged article 200, which is beneficial to improving the protective effect of the third limiting structure 30 on the packaged article 200 extending in a straight strip shape along the third direction e3, and further beneficial to improving the safety of the packaged article 200 during transportation.
[0057] In addition, the plurality of second limiting surfaces 23 of the third limiting structure 30 can be flexibly applied to packaged items 200 of various length specifications. Fig. 9As shown, when the packaged item 200 extending in a straight strip shape is transported through the packaging structure 100, the multiple second limiting surfaces 23 arranged along the third direction e3 can jointly limit the packaged item 200 with a longer length, and the packaged item 200 with a shorter length can also be jointly limited by the adjacent part of the second limiting surfaces 23 among the multiple second limiting surfaces 23. For example, when the length of the packaged item 200 in the straight strip shape is longer, the packaged item 200 contacts all the second limiting surfaces 23 of the third limiting structure 30 after being placed in the third limiting structure 30. For example, when the length of the packaged item 200 in the straight strip shape is shorter, the packaged item 200 contacts only part of the second limiting surfaces 23 when placed in the third limiting structure 30. In this way, the versatility of the third limiting structure 30 can be well improved, which is conducive to reducing the production and use costs of the packaging structure 100.
[0058] Furthermore, when the packaged items 200 are transported by the packaging structure 100, the placement position of the straight strip packaged items 200 can be flexibly selected, such as the straight strip packaged items 200 can be placed in the first limiting structure 10 or in the third limiting structure 30. At the same time, the placement position of the packaged items 200 can be flexibly selected according to the number and specifications of the packaged items 200 to be transported, such as Fig. 9 As shown, after the longer curved packaged item 200 is placed in the second limiting structure 20, the longer straight packaged item 200 can be placed in the third limiting structure 30, and the shorter straight packaged item 200 can be placed in the first limiting structure 10, so that the packaging structure 100 can accommodate a variety of packaged items 200 of different shapes and sizes, which is conducive to further improving the versatility of the packaged items 200.
[0059] According to some embodiments of the present invention, the second limiting surface 23 is parallel to the third direction e3. Therefore, after the straight strip packaged article 200 is placed in the third limiting structure 30, the second limiting surface 23 is parallel to the straight strip packaged article 200, so that the contact area between the second limiting surface 23 and the straight strip packaged article 200 can be increased, so that the fixing effect of the third limiting structure 30 on the straight strip packaged article 200 can be improved, and stress concentration on the straight strip packaged article can be avoided, which is conducive to improving the protective effect of the third limiting structure 30 on the straight strip packaged article 200.
[0060] According to some embodiments of the present invention, two second limiting surfaces 23 facing each other in the second direction e2 constitute a second limiting surface group 24 for clamping the packaged item 200, and in the third direction e3, the third limiting structure 30 includes at least a plurality of second limiting surface groups 24. In other words, when a straight strip-shaped packaged item 200 is placed between the two second limiting surfaces 23 of the second limiting surface group 24, the two second limiting surfaces 23 are respectively in contact with both sides of the packaged item 200 in the second direction e2, thereby clamping and fixing the packaged item 200 between the two first limiting surfaces 21, and the plurality of second limiting surface groups 24 can increase the clamping position of the third limiting structure 30 on the packaged item 200, which is conducive to improving the fixing effect of the third limiting structure 30.
[0061] According to some embodiments of the present invention, the first limiting structure 10 and the second limiting structure 30 share part of the limiting block 2. That is, the first limiting structure 10 and the third limiting structure 30 share part of the limiting block 2, and the part of the limiting block 2 shared by the first limiting structure 10 and the third limiting structure 30 can be used to limit the packaged item 200 placed in the first limiting structure 10, and can also be used to limit the packaged item 200 placed in the third limiting structure 30; the second limiting structure 20 and the third limiting structure 30 share part of the limiting block 2, and the part of the limiting block 2 shared by the second limiting structure 20 and the third limiting structure 30 can be used to limit the packaged item 200 placed in the second limiting structure 20, and can also be used to limit the packaged item 200 placed in the third limiting structure 30. Therefore, while ensuring the limiting effects of the first limiting structure 10, the second limiting structure 20 and the third limiting structure on the packaged item 200, it is helpful to reduce the number of limiting blocks 2, thereby reducing the space occupied by the limiting blocks 2, so as to reserve a larger placement space for the packaged item 200, which is helpful to increase the upper limit of the number of packaged items 200 that the packaging structure 100 can hold.
[0062] In a specific example, the projection of the limit block 2 on the reference plane is a polygon, the reference plane is perpendicular to the first direction e1, the side wall of the limit block 2 in the second direction e2 is the first limit surface 21, and the side wall of the limit block 2 in the second direction e2 is the second limit surface 23.
[0063] According to some embodiments of the present invention, the number of the limiting blocks 2 used to limit the position of the same packaged article 200 is not less than three. Thus, the limiting positions of the limiting blocks 2 on the packaged article 200 can be increased, thereby improving the limiting and fixing effect of the packaging structure 100 on the packaged article 200, so as to prevent the packaged article 200 from shaking and causing collision damage during transportation.
[0064] According to some optional embodiments of the present invention, in the circumferential direction of the stopper 2, any two adjacent side surfaces of the stopper 2 are smoothly transitioned in an arc shape. That is, the corners of the stopper 2 in the circumferential direction are rounded to prevent the corners of the stopper 2 in the circumferential direction from being too sharp and causing stress concentration on the packaged article 200 when contacting the packaged article 200. In this way, damage to the packaged article 200 due to stress concentration can be better avoided, which is conducive to improving the safety of the packaged article 200 during transportation.
[0065] According to some optional embodiments of the present invention, in the direction from the end where the stop block 2 is connected to the package body 1 to the end in the extension direction of the stop block 2, the projection area of the stop block 2 on the reference plane gradually decreases, the projection of the end in the extension direction of the stop block 2 on the reference plane is the first projection, the projection of the end where the stop block 2 is connected to the package body 1 on the reference plane is the second projection, and the first projection is within the range of the second projection. In other words, in the direction from the end where the stop block 2 is connected to the package body 1 to the end in the extension direction of the stop block 2, the outer peripheral wall of the stop block 2 extends inwardly and tilts, and at the same time, in the direction from the end where the stop block 2 is connected to the package body 1 to the end in the extension direction of the stop block 2, the spacing between the stop blocks 2 gradually decreases. Therefore, when the packaged item 200 is placed between the limit blocks 2, the inclined outer wall of the limit blocks 2 facilitates the packaged item 200 to enter between the limit blocks 2, which is beneficial to reducing the difficulty of taking and placing the packaged item 200. At the same time, the different spacings between the limit blocks 2 can adapt to the packaged items 200 of different diameters. For example, the area between the limit blocks 2 and the limit blocks 2 near the end of the limit blocks 2 in the extension direction can accommodate the packaged items 200 with a larger diameter, and the area between the limit blocks 2 and the limit blocks 2 near the end where the limit blocks 2 are connected to the packaging body 1 can accommodate the packaged items 200 with a smaller diameter, which is beneficial to further improve the versatility of the packaging structure 100.
[0066] In some examples, in the circumferential direction of the stopper 2, any two adjacent side surfaces of the stopper 2 are smoothly transitioned in an arc shape, and in the direction from the end of the stopper 2 connected to the packaging body 1 to the end of the stopper 2 in the extension direction, the projection area of the stopper 2 on the reference surface gradually decreases, the projection of the end of the stopper 2 in the extension direction on the reference surface is the first projection, and the projection of the end of the stopper 2 connected to the packaging body 1 on the reference surface is the second projection, and the first projection is within the range of the second projection. Thus, it is beneficial to improve the safety of the packaged item 200 during transportation, reduce the difficulty of taking and placing the packaged item 200, and improve the versatility of the packaging structure 100.
[0067] According to some embodiments of the present invention, the packaging structure 100 further includes: a limiting frame 3, which is provided on the packaging body 1 and located on the outer peripheral side of all the limiting blocks 2, and the limiting frame 3 is in a closed ring shape in the circumferential direction of the packaging body 1. That is, the limiting frame 3 surrounds the outer peripheral side of all the limiting blocks 2. Thus, the limiting frame 3 can prevent the packaged item 200 from sliding between the plurality of limiting blocks 2 from the outer peripheral side of all the limiting blocks 2, that is, the limiting frame 3 can enhance the fixing effect and protective effect of the packaging structure 100 on the packaged item 200, which is conducive to enhancing the safety of the packaged item 200 during transportation.
[0068] Furthermore, the limiting block 2 is located on the same side of the packaging body 1, and in the first direction e1, the end face of the limiting frame 3 away from the packaging body 1 is flush with the end face of the limiting block 2 away from the packaging body 1. That is to say, the end face of the limiting frame 3 away from the packaging body 1 and the end face of the limiting block 2 away from the packaging body 1 are on the same plane, that is, in the first direction e1, the height of the limiting frame 3 protruding from the packaging body 1 is the same as the height of the limiting block 2 protruding from the packaging body 1. Therefore, when the multi-layer packaging structure 100 is stacked, the lower side surface of the packaging body 1 of the packaging structure 100 located in the upper layer can be attached to the upper end face of the limiting frame 3 and the limiting block 2 of the packaging structure 100 located in the lower layer, so that the packaged items 200 in the packaging structure 100 in the lower layer can be restricted from above to prevent the packaged items 200 from moving upward and detaching from the limiting block 2, which is conducive to improving the safety of the packaged items 200 during transportation.
[0069] According to some embodiments of the present invention, the packaged article 200 is suitable for interference fit with the stop block 2. Thus, the close fit between the packaged article 200 and the stop block 2 can be well ensured, so that the packaged article 200 can be firmly placed to avoid the packaged article 200 from shaking and causing collision damage. At the same time, the matching mode between the packaged article 200 and the stop block 2 is simple, which is convenient for loading and unloading the packaged article 200. In a specific example, the packaging structure 100 is relatively soft. When the packaged article 200 is placed in the stop block 2, the stop block 2 can be deformed by pushing the packaged article 200 to squeeze it, so as to ensure that the stop block 2 can be closely attached to the packaged article 200, so as to improve the stability of the packaged article 200 after being placed in the packaging structure 100.
[0070] According to some embodiments of the present invention, the packaging structure 100 is a foam part. Among them, the foam is light in weight, environmentally friendly, has low production cost and is elastic. As a result, the weight, pollution and production cost of the packaging structure 100 can be reduced, and at the same time, it is ensured that the packaging structure 100 can produce a certain elastic deformation, so that the packaging structure 100 can buffer the external force extrusion generated during loading and unloading and transportation, thereby reducing the impact of external force on the packaged item 200 in the limit block 2, so as to improve the safety of the packaged item 200 during loading and unloading and transportation. In addition, in the process of placing the packaged item 200 on the limit block 2, the limit block 2 can be deformed by pushing the packaged item 200 to squeeze the limit block 2, so as to ensure that the limit block 2 can be closely attached to the packaged item 200, and the packaged item 200 is prevented from shaking during transportation, so as to further improve the safety of the packaged item 200 during transportation. In addition, the packaging structure 100 is also relatively soft, which can effectively prevent the packaging structure 100 from damaging the packaged item 200 due to excessive hardness.
[0071] In some examples, the packaging structure 100 is a foam piece, and the packaged piece 200 is suitable for interference fit with the limiting block 2 .
[0072] According to some embodiments of the present invention, the packaging structure 100 is symmetrical with respect to the second reference plane, the second reference plane is perpendicular to the third direction e3 and passes through the center of the packaging structure 100 in the second direction e2, the second direction e2 is perpendicular to the first direction e1, and the third direction e3 is perpendicular to the first direction e1 and perpendicular to the second direction e2. That is, the packaging structure 100 is a symmetrical structure, which helps to reduce the difficulty of designing and producing the packaging structure 100.
[0073] In a specific example, the packaged part 200 is a heating tube, the cross section of the packaged part 200 in the extension direction is annular, a groove is formed on the packaging body 1, the cross section of the groove in the extension direction is a concave arc and is adapted to the outer peripheral wall of the packaged part 200, which is conducive to further improving the fixing effect of the packaging structure 100 on the heating tube. The heating tube is one of a quartz heating tube, a ceramic heating tube, a carbon fiber heating tube or a graphite heating tube, which is not specifically limited.
