Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wheel hub packaging, and in particular to a wheel hub packaging material. Background Art

[0002] Wheel hub packaging materials, as a packaging equipment for facilitating the transportation and handling of wheel hubs, have been widely used in major car factories. In order to avoid damage to the wheel hubs during packaging, wheel hub packaging materials are generally packaged with high-density composite materials, such as high-density polyethylene. Since the hardness of these materials is much lower than that of the wheel hub, and at the same time, this material has the characteristics of high strength, light weight, easy manufacturing and low manufacturing cost, it is easier to package the wheel hub and transport it.

[0003] However, the inventors have discovered that although the partitions of some current wheel hub packaging materials are capable of positioning two sizes of wheel hubs, no matter which size of wheel hub is positioned, due to design and manufacturing errors, the wheel hub will be displaced in a local area after being positioned on the partition. As a result, after the wheel hub packaging material completes the packaging of multiple wheel hubs, these displacements of the wheel hub will cause unnecessary vibrations and / or shaking during transportation, and these vibrations and / or shaking will cause the surface of the wheel hub to be at risk of wear or damage. Summary of the invention

[0004] The purpose of the implementation mode of the present invention is to design a positioning structure and partition on the wheel hub, which can not only meet the packaging requirements of two different sizes of wheel hubs, but also improve the positioning performance of the wheel hub after packaging, and avoid unnecessary vibration and / or shaking of the wheel hub during transportation.

[0005] In order to achieve the above object, an embodiment of the present invention provides a partition, wherein the partition has a top side, a bottom side opposite to the top side, and at least one hub positioning structure arranged on the top side, each hub positioning structure comprising:

[0006] An upper positioning groove is used to be embedded in one end face of the wheel hub; the upper groove wall of the upper positioning groove is a first upper positioning surface that can fit with the outer ring of the wheel rim of the wheel hub;

[0007] A boss is surrounded by the upper positioning groove and is eccentrically arranged with respect to the upper positioning groove; the boss is used to enter the cavity of the hub when one end surface of the hub is embedded in the upper positioning groove; one side of the boss relative to the first upper positioning surface is a second upper positioning surface that can fit with the inner ring of the wheel rim of the hub;

[0008] Wherein, after the boss enters the cavity of the hub, at least a part of the first upper positioning surface and the second upper positioning surface respectively fit with the outer ring of the rim and the inner ring of the rim of the hub, so that the hub is positioned in the upper positioning groove.

[0009] In addition, an embodiment of the present invention provides a hub packaging material, including:

[0010] A plurality of partitions as described above, each of the partitions is arranged in sequence in the vertical direction, and a hub is positioned between every two adjacent partitions;

[0011] A cover plate, which is arranged on the top side of the partition located at the uppermost layer;

[0012] A tray, which is arranged on the bottom side of the partition located at the lowermost layer.

[0013] Compared with the prior art, in the embodiment of the present invention, since the upper positioning structure of the hub includes a boss and an upper positioning groove surrounding the boss, and the upper groove wall of the upper positioning groove is a first upper positioning surface that can fit with the outer ring of the rim of the hub, and one side of the boss relative to the first upper positioning surface is a second upper positioning surface that can fit with the inner ring of the rim of the hub. While the first upper positioning surface and the second upper positioning surface can respectively meet the packaging requirements of two different sizes of hubs, and because the boss and the upper positioning groove are eccentrically arranged, when the outer ring of the rim of one size of hub fits with the first upper positioning surface of the upper positioning groove, at this time, a part of the second upper positioning surface of the boss can also fit with the inner ring of the rim of this size of hub, so as to meet the positioning requirement of this size of hub in the upper positioning groove. Similarly, when the inner ring of the rim of another size of hub fits with the second upper positioning surface of the boss, at this time, a part of the first upper positioning surface of the upper positioning groove can fit with the outer ring of the rim of the hub, so as to meet the positioning requirement of this size of hub in the upper positioning groove. Since the first upper positioning surface and the second upper positioning surface can respectively fit with the outer ring and the inner ring of the rim of the hub when positioning different sizes of hubs, the uniqueness of the position of the hub on the partition is ensured, thereby preventing the hub from shifting on the partition and the hub from vibrating and / or shaking during transportation, thus reducing the risk probability of the hub being worn or damaged.

[0014] All in all, the eccentric design described herein can meet the positioning of various sizes of rims, and it is not easy to produce offsets between the upper and lower layers. At the same time, the partition parts in contact with the front and back of the hub all adopt a large-plane design, because a lot of concave and convex structures are reduced, and no partial stress concentration will occur for any size of rim, significantly reducing the risk of causing bruises and the like.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will elaborate on each embodiment of the present invention in conjunction with the drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be achieved.

[0026] Embodiment 1

[0027] The first embodiment of the present invention relates to a partition, as shown in Figure 1 and Figure 3As shown, the partition 1 has a top side 12, a bottom side 13 opposite to the top side 12, and at least one hub positioning structure disposed on the top side 12, such as Figure 1 , Figure 4 and Figure 5 shown. The hub positioning structure 11 includes: an upper positioning groove 111 and a boss 112.

[0028] Among them, in some embodiments, such as Figure 1 and Figure 2 shown, the upper positioning groove 111 is for the end face on one side of the hub 10 to be embedded, and the upper groove wall of the upper positioning groove 111 is a first upper positioning surface that can fit with the outer rim 102 of the rim of the hub 10.

[0029] Secondly, in some embodiments, such as Figure 1 and Figure 2 shown, the boss 112 is surrounded by the upper positioning groove 111, and the boss 112 is eccentrically arranged with the upper positioning groove 111. When the end face on one side of the hub 10 is embedded into the upper positioning groove 111, the boss 112 enters the cavity 103 of the hub 10. And, the side of the boss 112 relative to the first upper positioning surface 113 is a second upper positioning surface 114 that can fit with the inner rim 104 of the rim of the hub 10.

[0030] Among them, combined with Figure 5 shown, when the boss 112 enters the cavity 103 of the hub 10, at least part of the first upper positioning surface 113 and the second upper positioning surface 114 respectively fit with the outer rim 102 and the inner rim of the rim of the hub 10, so that the hub 10 is positioned in the upper positioning groove 111.

[0031] It can be easily seen from the above that since the positioning structure on the hub includes a boss 112 and an upper positioning groove 111 surrounding the boss 112, and the upper groove wall of the upper positioning groove 111 is a first upper positioning surface 113 that can fit with the outer ring of the rim of the hub, and one side of the boss 112 relative to the first upper positioning surface 113 is a second upper positioning surface 114 that can fit with the inner ring 104 of the rim of the hub 10. While the packaging requirements of two different sizes of hubs 10 can be met respectively by the first upper positioning surface 113 and the second upper positioning surface 114, and since the boss 112 and the upper positioning groove 111 are eccentrically arranged, when the outer ring 102 of the rim of one size of the hub 10 fits with the first upper positioning surface 113 of the upper positioning groove 111, at this time, a part of the second upper positioning surface 114 of the boss 112 can also fit with the inner ring 104 of the rim of this size of the hub 10, so as to meet the positioning requirement of this size of the hub 10 in the upper positioning groove 111. Similarly, when the inner ring 104 of the rim of the other size of the hub 10 fits with the second upper positioning surface 114 of the boss 112, at this time, a part of the first upper positioning surface 113 of the upper positioning groove 111 can fit with the outer ring 102 of the rim of the hub 10, so as to meet the positioning requirement of this size of the hub in the upper positioning groove. Since the first upper positioning surface 113 and the second upper positioning surface 114 can respectively fit with the outer ring 102 and the inner ring 104 of the rim of the hub 10 when positioning different sizes of the hub 10, the uniqueness of the position of the hub 10 on the partition 1 is ensured, thereby preventing the hub 10 from displacing on the partition 1 and the hub 10 from vibrating and / or shaking during transportation, and thus reducing the risk probability of the hub being worn or damaged.

[0032] Specifically, the positioning structure on the hub in this embodiment can position two different sizes of hubs 10. For example, as Figure 1 and Figure 2 shown, the large-sized hub 10 can be positioned by the first upper positioning surface 113 of the upper positioning groove 111, and the small-sized hub 10 can be positioned by the second upper positioning surface 114 of the boss 112. Specifically, when the boss 112 passes through the cavity 103 of the large-sized hub 10, combined with Figure 5 shown, at this time, most of the regions of the first upper positioning surface 113 can fit with the outer ring 102 of the rim of the hub 10, and at this time, a part of the second upper positioning surface 114 of the boss 11 is separated from the inner ring 104 of the rim of the hub 10, and at the same time, another part also fits with the inner ring 104 of the rim of the hub 10, so that this size of the hub 10 can be clamped by the first upper positioning surface 113 and the second upper positioning surface 114 and positioned in the upper positioning groove 111.

[0033] Similarly, when the boss 112 passes through the cavity 103 of the small-sized hub 10, combined with Figure 5As shown, at this time, most of the area of the second upper positioning surface 114 can be attached to the inner ring 104 of the rim of the hub 10. At this time, a part of the first upper positioning surface 113 of the upper positioning groove 111 is separated from the outer ring 102 of the rim of the hub 10, and at the same time, another part is attached to the outer ring 102 of the rim of the hub 10, so that the hub 10 of this size can also be clamped by the first upper positioning surface 113 and the second upper positioning surface 114 and positioned in the upper positioning groove 111 at this time.

[0034] It can be easily seen from the above that since at least a part of the first upper positioning surface 113 of the upper positioning groove 111 can be attached to the outer ring 102 of the rim of the hub 10, and at least a part of the second upper positioning surface 114 of the boss 112 can be attached to the inner ring 104 of the rim of the hub 10, therefore, by the attachment of the first upper positioning surface 113 and the second upper positioning surface 114 to the outer ring 102 and the inner ring 104 of the rim of the hub 10 respectively, the positioning requirements of the hubs 10 of two different sizes on the partition 1 can be met.

[0035] And, it is worth noting that in some embodiments, the first upper positioning surface 113 can be a continuous circular surface. Or, in some other embodiments, as Figure 1 and Figure 2 shown, the first upper positioning surface 113 includes: a plurality of concave first arc surfaces 1131 formed by interrupting around the axis of the upper positioning groove 111. And when the first upper positioning surface 113 includes: a plurality of concave first arc surfaces 1131 formed by interrupting around the axis of the upper positioning groove 111, as Figure 1 and Figure 2 shown, each first arc surface 1131 is arranged around the axis of the upper positioning groove 111. For example, each first arc surface 1131 can be arranged equidistantly around the axis of the upper positioning groove 111. Therefore, when each first arc surface 1131 is attached to the outer ring 102 of the rim of the hub 10, the acting force received by the hub 10 can be evenly distributed on the outer ring 102 of the rim of the hub 10, thereby further improving the positioning effect of the first upper positioning surface 113 on the hub 10.

[0036] In addition, since the upper positioning groove 111 and the boss 112 are eccentrically arranged, the vertical distance between at least one first arc surface 1131 and the second upper positioning surface 114 is less than the vertical distance between other first arc surfaces 1131 and the second upper positioning surface 114. Therefore, after the boss 112 enters the cavity 103 of the hub 10, combined with Figure 5As shown, at least one first arc surface 1131 of the upper positioning groove 111 can also cooperate with the second upper positioning surface 114 of the boss 112 to clamp the hub 10, thereby effectively preventing the hub 10 from shifting within the upper positioning groove 111 and ensuring the uniqueness of the position of the hub 10 within the upper positioning groove 111. For example, after the boss 112 enters the cavity 103 of the large-sized hub 10, multiple first arc surfaces 1131 of the upper positioning groove 111 can all be in contact with the outer rim 102 of the wheel rim of the hub 10, and a part of the second upper positioning surface 114 of the boss 112 can be in contact with the inner rim 104 of the wheel rim of the hub 10, so as to position the large-sized hub 10 within the upper positioning groove 111, ensure the uniqueness of the position of the hub 10 within the upper positioning groove 111, and prevent the phenomenon of displacement of the hub 10 of this size after positioning. Similarly, after the boss 112 enters the cavity 103 of the small-sized hub 10, as Figure 5 shown, the hub 10 can also be offset in the direction of at least one first arc surface 1131, so that the hub 10 can be clamped by the second upper positioning surface 114 of the boss 112 and at least one first arc surface 1131, thereby also ensuring the uniqueness of the position of the small-sized hub 10 within the upper positioning groove 111 and preventing the phenomenon of displacement of the hub 10 of this size after positioning.

[0037] In addition, it is worth mentioning that in some embodiments, as Figure 1 and Figure 2 shown, the second upper positioning surface 114 is a circular surface, so that when the second upper positioning surface 114 positions the hub 10, at least a part of the second upper positioning surface 114 can be in contact with at least a part of the inner rim 104 of the wheel rim of the hub 10. However, as an alternative solution, in some other embodiments, as Figure 1 and Figure 2 shown, a part of the boss 112 protrudes in the direction of the first upper positioning surface 113 along its circumferential direction to form a plurality of protruding portions 115, and the sides of the respective protruding portions 115 relative to the first upper positioning surface 113 together constitute the second upper positioning surface 114.

[0038] Specifically, as Figure 1 and Figure 2 shown, the sides of the respective protruding portions 115 relative to the first upper positioning surface 113 are all second arc surfaces 1141, and the vertical distance between at least one second arc surface 1141 and the first upper positioning surface 113 is less than the vertical distance between the other second arc surfaces 1141 and the first upper positioning surface 113. Therefore, after the boss 112 enters the cavity 103 of the hub 10, at least one second arc surface 1141 is in contact with the inner rim 104 of the wheel rim of the hub 10. For example, when positioning the large-sized hub 10, in combination with Figure 3 and Figure 5As shown, after the boss 112 enters the cavity 103 of the hub 10, most of the area of the first upper positioning surface 113 of the upper positioning groove 111 can be in contact with the outer rim 102 of the hub 10, and two of the second arc surfaces 1141 of the boss 112 can be in contact with the inner hub 104 of the hub 10. By the contact of the two second arc surfaces 1141 with the inner rim 104 of the hub 10, the positioning performance of the hub 10 in the upper positioning groove 111 can be further improved. Moreover, it should be noted that in some embodiments, the two second arc surfaces 1141 in contact with the inner rim 104 of the hub 10 can be symmetrically arranged with each other, so that the acting forces exerted by the two second arc surfaces 1141 on the inner rim 104 of the hub 10 can be better distributed on the inner rim 104 of the hub 10, and thus the positioning effect of the hub 10 in the upper positioning groove 111 can be further improved.

[0039] Moreover, as a preferred solution, in some embodiments, as Figure 6 and Figure 7 shown, there are multiple hub upper positioning structures 11, and the eccentric directions of the bosses 112 of every two adjacent hub upper positioning structures 11 are set in opposite directions away from each other, so that there is enough space between every two adjacent hub upper positioning structures 11, thus meeting the positioning requirements of larger-sized hubs 10 on the partition 1. At the same time, when each hub upper positioning structure 11 completes the positioning of each hub, interference during the installation and disassembly of two adjacent hubs 10 on the partition 1 can be avoided.

[0040] In addition, it is worth noting that in some embodiments, as Figure 3 and Figure 4 shown, the partition 1 further includes: at least one hub lower positioning structure 14. Each hub lower positioning structure 14 is arranged on the bottom side 13, and the number of the hub lower positioning structures 14 is the same as that of the hub upper positioning structures 11 and they are in one-to-one correspondence. Moreover, each hub lower positioning structure 14 includes: a first lower positioning surface 141 for positioning the hub 10 and a second lower positioning surface 142 for positioning the hub 10. Among them, the sizes of the hubs 10 positioned by the first lower positioning surface 141 and the second lower positioning surface 142 of each hub lower positioning structure 14 are different.

[0041] By arranging the hub lower positioning structures 14 on the bottom side 13 of the partition 1, after one end face of the hub 10 is positioned by the hub upper positioning structure 11 of the partition 1, the other end face of the hub 10 can be positioned by the hub lower positioning structure 14 of another partition 1, so that the hubs 10 can be stacked and placed in the vertical direction. Thus, while realizing the positioning of multiple hubs 10, the packing quantity of the hubs 10 can also be increased.

[0042] Moreover, it should be noted that in some embodiments, asFigure 3 and Figure 4 As shown in Figure 3 and Figure 4 , the lower positioning structure 14 of the wheel hub includes: a lower positioning groove 143 and a plurality of positioning protrusions 144. Among them, in some embodiments, such as Figure 3 and Figure 4 As shown in Figure 4 and Figure 3 , the lower positioning groove 143 is arranged on the bottom side 13 of the partition plate 1. The lower positioning groove 143 is used to be embedded by the other end face of the wheel hub 10. And the lower groove wall of the lower positioning groove 143 is a first lower positioning surface 141 that fits the outer ring 102 of the rim of the wheel hub 10. Secondly, in some other embodiments, such as Figure 4 As shown in Figure 5 and Figure 4 , each positioning protrusion 144 is formed on the bottom side 13 of the partition plate 1 around the axis of the lower positioning groove 143. Each positioning protrusion 144 is arranged around the axis of the lower positioning groove 143 on the bottom side 13 of the partition plate 1, and each positioning protrusion 144 surrounds the axis of the lower positioning groove 143 to form a positioning space (not marked in the figure) that can be embedded by the other end face of the wheel hub 10. And each positioning protrusion 144 has a second lower positioning surface 142 that can fit the outer ring 102 of the rim of the wheel hub 10. After the lower positioning groove 143 is embedded by the other end face of the wheel hub 10, combined with Figure 3 As shown in the figure and Figure 5 As shown in , at this time, the first lower positioning surface 141 fits the outer ring 102 of the rim of the wheel hub 10. And when the positioning space is embedded by the other end face of the wheel hub 10, combined with Figure 4 As shown in , at this time, the second lower positioning surfaces 142 of each positioning protrusion 144 can all fit the outer ring 102 of the rim of the wheel hub 10.

[0043] It can be easily seen from this that since each lower positioning structure 14 of the wheel hub includes: the lower positioning groove 143 arranged on the bottom side 13 of the partition plate 1 and a plurality of positioning protrusions 144, the lower positioning groove 143 and the positioning space surrounded by the plurality of positioning protrusions 144 can both be directly embedded by the other end face of the wheel hub 10. And the groove wall of the lower positioning groove 143 can be used as the first lower positioning surface 141. At the same time, each positioning protrusion 144 also has a second lower positioning surface 142 respectively. It can be easily seen from this that the first lower positioning surface 141 and each second lower positioning surface 142 are separated from each other. By the fitting of the first lower positioning surface 141 and the outer ring 102 of the wheel rim of the wheel hub 10, the positioning requirement of the partition plate 1 for the small-sized wheel hub 10 can be met. And by the fitting of each second lower positioning surface 142 and the outer ring 102 of the wheel rim of the wheel hub 10, the positioning requirement of the partition plate 1 for the large-sized wheel hub 10 can be met. Thus, the bottom side 13 of the partition plate 1 can also meet the packaging positioning requirements of two sizes of wheel hubs 10 respectively. Therefore, the production cost of the wheel hub packaging material is reduced.

[0044] And it should be noted that in the upper positioning structure of the wheel hub, such as Figure 1 and Figure 4As shown, the boss 112 is formed by extruding from the bottom side 13 to the top side 12 of the partition 1. At the same time, under the extrusion effect, the bottom side 13 of the partition 1 can form the lower positioning groove 143. It is not difficult to find from this that since the boss 112 of the partition 1 is formed by the partition 1 itself protruding through extrusion, rather than an additional component added to the partition 1, the mass of the partition 1 will not be increased. While not affecting the positioning performance of the partition 1 for the cover plate 2 and the tray 3 respectively, the mass of the partition 1 will not be increased either, making it more convenient for the staff to carry and move the partition 1.

[0045] Embodiment 2

[0046] Embodiment 2 of the present invention relates to a wheel hub packaging material, such as Figure 9 shown, including: a plurality of partitions 1, a cover plate 2 and a tray 3 as described in Embodiment 1.

[0047] Among them, as Figure 9 shown, the partitions 1 are arranged in sequence along the vertical direction, and each adjacent two partitions 1 are used to position the wheel hub 10. Secondly, as Figure 8 shown, the cover plate 2 is arranged on the top side 12 of the partition 1 located at the uppermost layer. And, as combined with Figure 5 shown, an upper mounting structure 21 is formed on one side of the cover plate 2 relative to the partition 1, and this upper mounting structure 21 is used for the cover plate 2 to be positioned on the top side 12 of this partition 1. Finally, as combined with Figure 7 and Figure 9 shown, the tray 3 is arranged on the bottom side 13 of the partition 1 located at the lowermost layer. And, a lower mounting structure 31 is formed on one side of the tray 3 relative to the partition 1, and this lower mounting structure 31 is used for the tray 3 to be positioned on the bottom side 13 of this partition 1.

[0048] When it is necessary to package multiple wheel hubs 10, as combined with Figure 5 and Figure 9 shown, one of the partitions 1 can support one end face of the wheel hub 10, so that one end face of the wheel hub 10 can be directly embedded into the upper positioning groove 111 of this partition 1. At the same time, another partition 1 is covered on the other end face of the wheel hub 10, so that the other end face of the wheel hub 10 can be directly embedded into the lower positioning groove 143 of this partition 1 or into the positioning space of this partition 1. Therefore, by arranging multiple partitions 1 in sequence from bottom to top, the packaging requirements of multiple wheel hubs 10 can be satisfied simultaneously.

[0049] In addition, it is not difficult to see from the contents of Example 1 that since the top side 12 and the bottom side 13 of the partition 1 are respectively provided with the wheel hub upper positioning structure 11 and the wheel hub lower positioning structure 14, and the wheel hub upper positioning structure 11 includes a first upper positioning surface 113 and a second upper positioning surface 114, two wheel hubs of different sizes can be positioned respectively through the first upper positioning surface 113 and the second upper positioning surface 114, and similarly, the wheel hub lower positioning structure 14 includes a first lower positioning surface 141 and a second lower positioning surface 142, and two wheel hubs of different sizes can also be positioned respectively through the first lower positioning surface 141 and the second lower positioning surface 142, so that the partition 1 can respectively meet the packaging positioning requirements of the two wheel hubs 10 of different sizes, thereby reducing the production cost of the wheel hub packaging material. Furthermore, by providing a cover plate 2 on the top side 12 of the uppermost partition plate 1 and a pallet 3 on the bottom side 13 of the lowermost partition plate 1, not only can the packaged wheel hub 10 be handled and transported easily, but also the cover plate 2 and the pallet 3 can effectively protect the uppermost and lowermost partition plates 1, thereby preventing the partition plates 1 from being deformed due to external factors during handling or transportation of the wheel hub packaging material.

[0050] Specifically, in some embodiments, Figure 6 As shown, the upper mounting structure 21 includes: a plurality of upper limit protrusions 213, and each upper limit protrusion 213 is formed on one side of the cover plate 2 relative to the partition plate 1, and each upper limit protrusion 213 is used to be embedded in at least one upper limit groove 116 provided on the top side 12 of the partition plate 1, so that the cover plate 2 can be positioned on the top side 12 of the partition plate 1. Figure 8 and Figure 4 As shown, the lower mounting structure 31 includes: a plurality of lower limit protrusions 311, and each lower limit protrusion 311 is formed on a side of the tray 3 relative to the partition 1, and each lower limit protrusion 311 is used to be embedded in at least one lower limit groove 131 arranged on the bottom side 13 of the partition 1, so that the tray 3 is positioned on the bottom side 13 of the partition 1.

[0051] And, as a preferred solution, in some embodiments, such as Figure 7 As shown, the side of the cover plate 2 facing away from the partition 1 is partially protruded to form a plurality of support protrusions 22. Through each support protrusion 22, when the completed wheel hub packaging material is transported, the upper surface of the cover plate 2 can be prevented from being directly subjected to force, effectively reducing the possibility of deformation of the cover plate 2. In addition, due to the presence of the support protrusions 22, when the cover plate 2 is placed in reverse, each support protrusion 22 can contact the table or the ground, thereby preventing the upper surface of the cover plate 2 from directly contacting the table or the ground, ensuring that a certain gap can be formed between the upper surface of the cover plate 2 and the table or the ground, so that the cover plate 2 can be easily moved and taken.

[0052] In addition, in some other embodiments, Figure 8 and Figure 9As shown, a part of the side of the tray 3 facing away from the partition 1 protrudes to form a plurality of supporting corners 32. Through each supporting corner 32, the placement of the tray 3 can be facilitated, and the lower surface of the tray 3 can be prevented from directly contacting the tabletop or the ground. At the same time, the supporting performance of the tray 3 can also be improved.

[0053] In addition, in some embodiments, the parts where the cover plate 2 abuts against each hub 10 are all planes. Since the parts where the cover plate 2 abuts against the hub 10 are planes 211, after the cover plate 2 abuts against the hub 10, the wear caused by the cover plate 2 to the hub 10 can be reduced, thereby further protecting the hub 10.

[0054] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention. In actual applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
