Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a liner for protecting the wheels of a lawnmower and a cardboard box containing the liner. Background Technology

[0002] Because the front wheel spacing of a four-wheeled lawnmower is smaller than the rear wheel spacing, during packaging, the rear wheels are closer to the inner walls of the packaging box, while there is a gap between the front wheels and the inner walls. Furthermore, the four-wheeled lawnmower has a counterweight at the front, and most of the wheels are injection-molded, connected to the machine via metal axles. Therefore, during drop tests and other tests, this gap causes the front wheels to shift inside the packaging box. Additionally, the inertia of the counterweight can easily damage the metal axles, leading to jamming or even detachment of the front wheels. Moreover, the impact of the front wheels on the packaging box can also cause structural damage. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a liner for protecting the wheels of a lawnmower and a cardboard box containing the liner, which can effectively protect the equipment inside the cardboard box from damage.

[0004] This utility model is achieved through the following technical solution:

[0005] In a first aspect, this utility model provides a liner for protecting the wheels of a lawnmower, comprising:

[0006] Base plate;

[0007] A front baffle is connected to one side of the base plate along a first direction, and a first fold line is formed at the connection between the front baffle and the base plate;

[0008] A pair of side baffles, the pair of side baffles being respectively connected to both sides of the base plate along the second direction, and a second fold line being formed at the connection between the pair of side baffles and the base plate;

[0009] Wherein, the first direction is perpendicular to the second direction;

[0010] A third fold line, parallel to the first fold line, is formed in the middle of the base plate, dividing the base plate into a first base plate and a second base plate. The first base plate connects the front baffle and the pair of side baffles.

[0011] When the front baffle, the pair of side baffles and the second bottom plate bend toward the first bottom plate along the first fold line, the second fold line and the third fold line respectively, the front baffle and the pair of side baffles are interconnected and form a limited space with the bottom plate;

[0012] After the limiting space is formed, the end of the bent bottom plate away from the front baffle is shorter than the end of the side baffle away from the front baffle in the first direction, and the end of the bent bottom plate away from the front baffle is used to abut the walking wheel.

[0013] Optionally, a fourth fold line is formed in the middle of the front baffle, the fourth fold line being parallel to the first fold line, to divide the front baffle into a first front baffle and a second front baffle, the first front baffle being connected to the first bottom plate.

[0014] The second front baffle and the first front baffle are bent toward the base plate along the fourth fold line and the first fold line, respectively, so that the end of the second front baffle away from the first front baffle is connected to the base plate, forming the front shield of the limiting space.

[0015] Optionally, the fourth broken line has a predetermined width;

[0016] The side baffle includes a first side baffle.

[0017] A fifth fold line parallel to the third fold line is formed in the middle of the first side baffle. The fifth fold line divides the first side baffle into a first front side baffle and a first rear side baffle. The first rear side baffle is connected to the first bottom plate through the second fold line.

[0018] Wherein, the first front baffle is used to bend along the second fold line and then bend along the fifth fold line to embed into the width space formed by the second front baffle and the first front baffle after the second front baffle is bent along the fourth fold line.

[0019] Optionally, a first frame groove is formed on the first base plate near the first fold line, and a first protrusion is formed on the end of the second front baffle away from the first front baffle.

[0020] Wherein, after the first front baffle and the second front baffle are bent along the first fold line and the fourth fold line respectively, the first protrusion is embedded in the first frame groove to self-lock the second front baffle with the first bottom plate.

[0021] Optionally, the side baffle further includes a second side baffle.

[0022] The second side baffle is connected to the side of the first side baffle that is away from the first bottom plate.

[0023] A sixth fold line parallel to the first fold line is formed in the middle of the second side baffle. The sixth fold line divides the second side baffle into a second front side baffle and a second rear side baffle. The second rear side baffle connects to the first rear side baffle, and a seventh fold line is formed at the connection point between them.

[0024] The second front baffle and the second rear baffle are respectively bent along the sixth fold line and the seventh fold line toward the first base plate and then closely attached to the first rear baffle to form a side shield of the limiting space.

[0025] Optionally, the sixth and seventh fold lines have predetermined widths, and a second protrusion is formed on the back side at the position of the sixth fold line.

[0026] The second front baffle has first grooves formed on both sides near the first side baffle.

[0027] The second protrusion is embedded in the first groove to self-lock the formed side shield with the front shield.

[0028] Optionally, with the axis of symmetry of the front baffle along the second direction as the axis of symmetry, the first front baffle is symmetrically formed with an eighth broken line on each side, and the second front baffle is symmetrically formed with a ninth broken line on each side.

[0029] The eighth fold line divides the first front baffle into a middle first front baffle body and two symmetrical third side baffles on both sides. The ninth fold line divides the second front baffle into a middle second front baffle body and two symmetrical fourth side baffles on both sides. The first front baffle body is connected to the second front baffle body through the fourth fold line. The first front baffle body is connected to the first bottom plate through the first fold line.

[0030] Wherein, after the second front baffle body is bent and attached to the first front baffle body along the fourth fold line, the third side baffle is attached to the fourth side baffle, the third side baffle and the fourth side baffle are folded inward along the eighth fold line and the ninth fold line respectively, and the first front baffle is bent along the first fold line. At this time, the first front baffle and the second front baffle form the front shield of the limiting space, and the third side baffle and the fourth side baffle form the side shield of the limiting space.

[0031] Optionally, in the direction along the first broken line, the eighth broken line is located inside the second broken line, and the ninth broken line is located inside the eighth broken line.

[0032] Optionally, a tenth fold line parallel to the second fold line is formed on the side baffle.

[0033] The tenth fold line divides the side baffle into a fifth side baffle and a sixth side baffle, and the fifth side baffle is connected to the first bottom plate through the second fold line;

[0034] The fifth side baffle and the sixth side baffle are bent along the second fold line and the tenth fold line, respectively, so as to cover the third side baffle and the fourth side baffle within the width space formed between the fifth side baffle and the sixth side baffle.

[0035] Optionally, the end of the sixth side baffle near the front baffle is shorter in the first direction than the end of the fifth side baffle near the front baffle.

[0036] The tenth fold line has a predetermined width, and the end of the tenth fold line near the front baffle has a slope, and the slope gradually decreases in the direction away from the fifth side baffle.

[0037] Optionally, a third protrusion is formed at the end of the sixth side baffle away from the fifth side baffle.

[0038] Second frame grooves are formed on both sides of the first base plate near the second fold line.

[0039] The third protrusion is embedded in the second frame groove to self-lock the sixth side baffle with the first base plate.

[0040] Optionally, a second groove is formed at the end of the second front baffle away from the first front baffle.

[0041] The second base plate has a fourth protrusion at the end furthest from the first base plate.

[0042] The fourth protrusion is used to embed into the second groove when the second base plate is bent along the third fold line to self-lock the base plate with the formed front shield.

[0043] Optionally, the two ends of the side of the second base plate in the first direction are shorter than the two ends of the first base plate;

[0044] The two ends of the side of the second base plate in the first direction are respectively separated from the inner end of the side baffle.

[0045] Secondly, this utility model provides a cardboard packaging box, including the inner lining for the protective wheels of a lawnmower according to any of the embodiments of the first aspect.

[0046] Compared with existing technologies, the advantages of this utility model are:

[0047] 1. The inner lining of the protective lawnmower wheels of this utility model consists of a front baffle and a pair of side baffles bent at 90° along the first and second fold lines towards the bottom plate, respectively, forming a front shield and a side shield. A second bottom plate on the bottom plate is bent at 180° along the third fold line towards the first bottom plate, achieving overlap between the first and second bottom plates, thus forming a bottom pad. Finally, the front shield, side shield, and bottom pad form a limiting space to line the front wheels of the lawnmower placed in a cardboard box, effectively protecting the lawnmower from damage during testing.

[0048] 2. The side baffles of the inner lining of the protective lawnmower wheels of this utility model can line the outer end of the front wheel, thereby compensating for the width difference between the front and rear wheels inside the cardboard box. This ensures that both the front and rear wheels are tightly wrapped against the inner walls of both sides of the cardboard box, thus preventing the front wheels or the machine body of the lawnmower from impacting the front of the cardboard box during testing, which could cause damage to the top and structure. It effectively limits the front of the machine body, achieving indirect protection.

[0049] 3. The inner lining of the protective lawnmower's traveling wheels of this utility model has an opening between the end of the bent bottom plate away from the front baffle and the end of the side baffle away from the front baffle. Therefore, when placing the lawnmower, the front wheel surface of the traveling wheel abuts against the end of the bottom lining (i.e., the end of the bottom plate away from the front baffle), and the bottom of the traveling wheel rests inside the opening, rather than on the bottom lining formed by the bent bottom plate. This prevents the entire machine from being raised when lining the lawnmower inside a cardboard box, thus achieving the requirement of miniaturized cardboard packaging. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0060] The following is a detailed description of the inner lining of the protective lawnmower wheels of this utility model, with reference to the accompanying drawings.

[0061] like Figures 1 to 4As shown, this utility model provides a protective liner for the wheels of a lawnmower, which may include: a base plate 100, a front baffle 200, and a pair of side baffles 300. The front baffle 200 is connected to one side of the base plate 100 along a first direction, and a first fold line 1 is formed at the connection between the front baffle 200 and the base plate 100. The pair of side baffles 300 are respectively connected to both sides of the base plate 100 along a second direction, and a second fold line 2 is formed at the connection between the pair of side baffles 300 and the base plate 100. The first direction (e.g., the length direction) is perpendicular to the second direction (e.g., the width direction). A third fold line 3, parallel to the first fold line 1, is formed in the middle of the base plate 100. The third fold line 3 divides the base plate 100 into a first base plate 110 and a second base plate 120. The first base plate 110 connects the front baffle 200 and a pair of side baffles 300. When the front baffle 200, the pair of side baffles 300, and the second base plate 120 are bent toward the first base plate 110 along the first fold line 1, the second fold line 2, and the third fold line 3, respectively, the front baffle 200 and the pair of side baffles 300 are interconnected and form a limiting space with the base plate 100. After the limiting space is formed, the end of the bent base plate 100 away from the front baffle 100 is shorter in a first direction than the end of the side baffles 300 away from the front baffle 100. The end of the bent base plate 100 away from the front baffle 200 is used to abut against the driving wheel (for example, it can be the lower surface of the front end of the driving wheel).

[0062] Specifically, the inner lining of the protective lawnmower wheels of this utility model is provided with a base plate 100, a front baffle 200 connected to the front end of the base plate 100, and side baffles 300 respectively connected to both sides of the base plate 100. The front baffle 200 and the pair of side baffles 300 are bent at 90° towards the base plate 100 along the first fold line 1 and the second fold line 2, respectively, to form a front shield and a side shield. The base plate 100 also has a third fold line 3 parallel to the first fold line 1 in the middle, which divides the base plate 100 into a first base plate 110 and a second base plate 120 in the direction away from the front baffle 200. The front baffle 200 and a pair of side baffles 300 are respectively connected to the first base plate 110. The second base plate 120 is bent 180° towards the first base plate 110 along the third fold line 3, so that the first base plate 110 and the second base plate 120 overlap to form a bottom pad. Finally, the front baffle, the side baffle and the bottom pad form a limiting space to line the front wheel side of the lawnmower placed in the cardboard box, which can effectively protect the lawnmower in the cardboard box from damage during the test.

[0063] More specifically, such as Figure 5As shown, since there is a slight difference in width between the front wheels 1010 and the rear wheels 1020 of the lawnmower, specifically a distance d between the outer ends of the front wheels 1010 and the rear wheels 1020, the side baffles 300 of the protective liner of the lawnmower wheels of this invention can line the outer ends of the front wheels 1010, thereby compensating for the width difference between the front wheels 1010 and the rear wheels 1020 inside the cardboard box, ensuring that both the front wheels 1010 and the rear wheels 1020 are tightly packed against the inner walls of both sides of the cardboard box. Furthermore, during testing, the front wheels 1010 or the machine itself impacted the front end of the cardboard box, causing damage to the top and structure. The front baffles 200 of the liner of this invention effectively limit the front end of the machine, achieving indirect protection.

[0064] Furthermore, after the limiting space is formed, the length of the bent bottom plate 100 (i.e., the bottom pad formed by the overlap of the first bottom plate 110 and the second bottom plate 120) is shorter than that of the side baffle 300 in the direction perpendicular to the first fold line 1, so that an opening is formed between the end of the bottom plate 100 away from the front baffle 200 and the end of the side baffle 300 away from the front baffle 200. Therefore, when placing the lawnmower, the front wheel surface of the front wheel 1010 abuts against the end of the bottom pad (i.e., the end of the bottom plate 100 away from the front baffle 200), and the bottom of the front wheel 1010 rests inside the opening, rather than on the bottom pad formed by the bending of the bottom plate 100. Thus, when lining the lawnmower inside the cardboard box, the entire machine is not raised, achieving the requirement of miniaturization in cardboard packaging.

[0065] In addition, the outer edge of the front wheel is curved, and the inner liner is formed at a right angle inside it, creating a cavity below the front wheel. During a drop test, this cavity needs to completely deform and contact the front wheel for the front wheel to fully withstand the impact force. In other words, after the inner liner is formed, it ensures that the packaging carton and the inner liner have room for relative deformation, and the impact force will not directly contact the wheel, thus achieving the purpose of bearing the maximum impact force instead of the front wheel, thereby providing protection.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, a fourth fold line 4 is formed in the middle of the front baffle 200, which is parallel to the first fold line 1, dividing the front baffle 200 into a first front baffle 210 and a second front baffle 220. The first front baffle 210 is connected to the first base plate 110. The second front baffle 220 and the first front baffle 210 are bent towards the base plate 100 along the fourth fold line 4 and the first fold line 1, respectively, so that the end of the second front baffle 220 away from the first front baffle 210 is connected to the base plate 100, forming a front shield for limiting the space.

[0067] In other words, a fourth fold line 4 parallel to the first fold line 1 is set in the middle of the front baffle 200, so that the first front baffle 210 and the second front baffle 220 are formed. The second front baffle 220 is bent 180° along the fourth fold line 4 toward the bottom plate 100 to form a front shield with a certain thickness, thereby improving the protection of the front end of the lawnmower.

[0068] In some embodiments, such as Figure 1 As shown, the fourth fold line 4 has a predetermined width, for example, it can be configured as a double fold line with a predetermined spacing. The side baffle 300 may include a first side baffle 310, in which a fifth fold line 5 parallel to the third fold line 3 is formed in the middle. The fifth fold line 5 divides the first side baffle 310 into a first front side baffle 312 and a first rear side baffle 311. The first rear side baffle 311 is connected to the first bottom plate 110 through a second fold line 2. The first front side baffle 312 is used to bend along the second fold line 2 and then along the fifth fold line 5 after the first rear side baffle 311 is bent, and then embedded in the width space formed by the second front baffle 220 after it is bent along the fourth fold line 4 and the first front baffle 210.

[0069] Specifically, the side panel 300 is provided with a fifth fold line 5 parallel to the third fold line 3, dividing it into a first front side panel 312 and a first rear side panel 311. The first front side panel 312 is bent along the fifth fold line 5 and then embedded into the width space formed by the second front panel 220 bent along the fourth fold line 4 and the first front panel 210, thereby increasing the thickness of the front shield to accommodate the inner linings of different sizes of lawnmowers. The first rear side panel 311 is bent along the second fold line 2 to form a side shield with a limiting space. In addition, the distance between the front wheels of the inner lining and the inner wall of the front side of the packaging box can be further controlled by adjusting the number of folds of the first front side panel 312 itself, for example, by folding it along a direction parallel to the fifth fold line 5.

[0070] In some embodiments, a first frame groove 111 is formed on the first base plate 110 near the first fold line 1, and a first protrusion 221 is formed on the end of the second front baffle 220 away from the first front baffle 210. After the first front baffle 210 and the second front baffle 220 are bent along the first fold line 1 and the fourth fold line 4 respectively, the first protrusion 221 is embedded in the first frame groove 111 to self-lock the second front baffle 220 to the first base plate 110.

[0071] As an example, such as Figure 1 and Figure 2As shown, a pair of first frame grooves 111 can be provided on the first base plate 110 near the first fold line 1. The pair of first frame grooves 111 are symmetrically arranged on both sides of the first base plate 110 along the direction of the first fold line 1. The end of the second front baffle 220 away from the first front baffle 210 is provided with a pair of first protrusions 221 corresponding to the pair of first frame grooves 111. The pair of first protrusions 221 are respectively embedded into the pair of first frame grooves 111, thereby realizing the detachable self-locking of the second front baffle 220 and the first base plate 110, which is convenient and reliable, and makes the front blocking structure of the formed limiting space more robust.

[0072] In some embodiments, such as Figure 1 As shown, the side baffle 300 may further include a second side baffle 320, which connects to the side of the first side baffle 310 away from the first base plate 110. A sixth fold line 6, parallel to the first fold line 1, is formed in the middle of the second side baffle 320. The sixth fold line 6 divides the second side baffle 320 into a second front side baffle 322 and a second rear side baffle 321. The second rear side baffle 321 connects to the first rear side baffle 311, and a seventh fold line 7 is formed at the connection point between them. The second front side baffle 322 and the second rear side baffle 321 are used to bend along the sixth fold line 6 and the seventh fold line 7 towards the first base plate 110 and then closely adhere to the first rear side baffle 311, forming a side shielding of the limiting space.

[0073] In other words, a second side baffle 320 is connected to the outside of the first side baffle 310. The second side baffle 320 has a sixth fold line 6 parallel to the first fold line 1. The sixth fold line 6 divides the second side baffle 320 into a second front side baffle 322 and a second rear side baffle 321 that match the size of the first rear side baffle 311. The second front side baffle 322 and the second rear side baffle 321 are bent 180° towards the first base plate 110 along the sixth fold line 6 and the seventh fold line 7, respectively, and then closely adhere to the first rear side baffle 311 to form a side shield with a limiting space. The folding arrangement of the second side baffle 320 increases the thickness of the side shield, making it suitable for the inner lining of lawnmowers of different widths. In addition, two or more sixth fold lines 6 can be provided on the second side baffle 320, such as multiple second front side baffles 322 and second rear side baffles 321 connected in sequence, so as to fold the second side baffle 320 into more layers, thereby further adjusting the thickness of the side shielding.

[0074] In some embodiments, such as Figure 1As shown, the sixth fold line 6 and the seventh fold line 7 have a predetermined width, for example, they can be set as double fold lines with a predetermined spacing. A second protrusion 323 is formed on the back side of the sixth fold line 6. A first groove 222 is formed on the side of the second front baffle 220 near the first side baffle 310. The second protrusion 323 is embedded in the first groove 222 to self-lock the formed side baffle and front baffle.

[0075] Thus, after the second front side baffle 322 and the second rear side baffle 321 are bent to form a side shield, and the second front baffle 220 and the first front baffle 210 are bent to form a front shield, the second protrusion 323 is embedded in the first groove 222 so that the side shield and the adjacent vertical side of the front shield are stably locked together, thereby improving the stability and firmness of the inner lining structure.

[0076] In other embodiments, such as Figure 3 and Figure 4 As shown, with the axis of symmetry of the front baffle 200 along the second direction (i.e., the width direction) as the axis of symmetry, the first front baffle 210 has an eighth fold line 8 symmetrically formed on both sides, and the second front baffle 220 has a ninth fold line 9 symmetrically formed on both sides. The eighth fold line 8 divides the first front baffle 210 into a middle first front baffle body 211 and two symmetrical third side baffles 212. The ninth fold line 9 divides the second front baffle 220 into a middle second front baffle body 223 and two symmetrical fourth side baffles 224. The first front baffle body 211 is connected to the second front baffle body 223 through the fourth fold line 4, and the first front baffle body 211 is connected to the first base plate 110 through the first fold line 1. In this process, after the second front baffle body 223 is bent and attached to the first front baffle body 211 along the fourth fold line 4, the third side baffle 212 and the fourth side baffle 224 are attached together. The third side baffle 212 and the fourth side baffle 224 are folded inward along the eighth fold line 8 and the ninth fold line 9, respectively. The first front baffle 210 is bent along the first fold line 1. At this time, the first front baffle 210 and the second front baffle 220 form a front shield of the limiting space, and the third side baffle 212 and the fourth side baffle 224 form a side shield of the limiting space.

[0077] Specifically, in this embodiment, the lining of the protective lawnmower wheels is formed by the second front baffle body 223 being bent 180° along the fourth fold line 4 and overlapping with the first front baffle body 211 to form a front shield of a certain thickness, which is used to adapt to the lining of equipment of different length sizes inside the packaging box; and the third side baffle 212 is overlapped with the corresponding fourth side baffle 224 to form a side shield of a certain thickness, which is used to match the lining of equipment of different width sizes inside the packaging box.

[0078] Furthermore, along the direction of the first fold line 1, the eighth fold line 8 is located inside the second fold line 2, and the ninth fold line 9 is located inside the eighth fold line 8. This allows for a perfect matching of the thicknesses of the various parts of the inner lining material, ensuring a seamless integration and preventing problems such as interference during bending and incomplete sealing.

[0079] In other embodiments, such as Figure 3 and Figure 4 As shown, a tenth fold line 10 parallel to the second fold line 2 is formed on the side baffle 300.

[0080] The tenth fold line 10 divides the side baffle 300 into a fifth side baffle 330 and a sixth side baffle 340. The fifth side baffle 330 is connected to the first base plate 110 via the second fold line 2. The fifth side baffle 330 and the sixth side baffle 340 are bent along the second fold line 2 and the tenth fold line 10, respectively, so as to cover the third side baffle 212 and the fourth side baffle 224 within the width space formed between the fifth side baffle 330 and the sixth side baffle 340.

[0081] Therefore, by bending the fifth side baffle 330 and the sixth side baffle 340 along the second fold line 2 and the tenth fold line 10 respectively to cover and overlap the third side baffle 212 and the fourth side baffle 224, the side shielding can be made into a complete whole, and the thickness of the side shielding can be adjusted.

[0082] In other embodiments, such as Figure 3 and Figure 4 As shown, the end of the sixth side baffle 340 near the front baffle 200 is shorter than the end of the fifth side baffle 330 near the front baffle 200 in the first direction (i.e., the direction perpendicular to the first fold line 1). The tenth fold line 10 has a predetermined width, and the end of the tenth fold line 10 near the front baffle 200 is formed with a slope, and the slope gradually decreases in the direction away from the fifth side baffle 330.

[0083] Therefore, when the end of the sixth side baffle 340 near the front baffle 200 is bent and covers the third side baffle 212 and the fourth side baffle 224, it can fit the thickness of the third side baffle 212 and the fourth side baffle 224, thus achieving an interference fit between the sixth side baffle 340 and the front baffle 200. In addition, it also plays a role in improving the strength of the inner lining structure.

[0084] In other embodiments, such as Figure 3 and Figure 4As shown, a third protrusion 341 is formed at the end of the sixth side baffle 340 away from the fifth side baffle 330. Second frame grooves 112 are formed on both sides of the first base plate 110 near the second fold line 2. The third protrusion 341 is embedded in the second frame grooves 112 to self-lock the sixth side baffle 340 to the first base plate 110.

[0085] This facilitates the formation of a side-shading structure and improves the stability of the lining.

[0086] In some embodiments, such as Figure 1 and Figure 3 As shown, a second groove 225 is formed at the end of the second front baffle 220 away from the first front baffle 210, and a fourth protrusion 121 is formed at the end of the second bottom plate 120 away from the first bottom plate 110. The fourth protrusion 121 is used to embed into the second groove 225 when the second bottom plate 120 is bent along the third fold line 3 to self-lock the bottom plate 100 with the formed front baffle.

[0087] This facilitates the locking of the bent bottom plate 100 (including the first bottom plate 110 and the second bottom plate 120) with the bent front baffle 200 (including the first front baffle 210 and the second front baffle 220), and the two ends of the locked second bottom plate 120 are respectively interference-fitted with the formed side shields, thereby enhancing the overall structural strength of the lining.

[0088] In some embodiments, such as Figure 1 and Figure 3 As shown, the two ends of the side of the second base plate 120 in the first direction (i.e., along the direction of the third fold line 3) are shorter than the two ends of the first base plate 110. The two ends of the side of the second base plate 120 in the first direction form a gap region 130 with the inner end of the side baffle 300.

[0089] In other words, by setting the interval area 130, sufficient thickness space is provided for the formation of the side shield (composed of the sixth side baffle 340, the fifth side baffle 330, the third side baffle 212 and the fourth side baffle 224 stacked together), so that when the second base plate 120 is bent along the third fold line 3, its two ends can be folded and tightly attached to the surface of the first base plate 110.

[0090] In summary, the liner of this invention protects the front wheel of the lawnmower from shaking during transportation by using its front and sides. The front side also serves to prevent air leakage from the packaging box. During packaging, the carton is typically placed directly against the front wheel. Without the liner, the carton might come into contact with the wheel during transport, causing it to be crushed and deformed. With the liner, its front side is positioned inside the carton, raising the bottom of the carton and preventing direct contact with the front wheel, thus achieving air leakage. Furthermore, the impact of a fall by the front wheel is largely absorbed by the cardboard around the liner, and the inherent strength of the liner's structure effectively prevents deformation or damage to the front wheel.

[0091] Secondly, this utility model provides a cardboard packaging box, including the inner lining for the protective wheels of a lawnmower according to any of the embodiments of the first aspect.

[0092] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
