[0006] In some embodiments, in the upward direction, the outer walls of the support are provided with equal diameters, and the outer diameter of the top end of the second positioning part is equal to the outer diameter of the support.

[0007] In some embodiments, the outer surface of the second positioning portion is located on the extended surface of the outer surface of the first positioning portion.

[0008] In some embodiments, a round head located at the top of the first positioning portion is further included, the surface of which is arc-shaped.

[0009] In some embodiments, the bottom surface of the second positioning part has a clearance groove.

[0010] In some embodiments, the bottom surface of the second positioning part has a downwardly protruding limiting ring.

[0011] In some embodiments, both the first positioning part and the second positioning part are frustum-shaped, and the support is cylindrical.

[0012] According to a second aspect of the present invention, an embodiment of the present invention provides a combined structure of a top cover and a support foot, including a guide-type top cover and a support foot as described in any of the first aspects above. The bottom surface of the support foot is provided with a positioning hole, and the inner wall of the positioning hole is provided with a protruding ring. The inner side of the protruding ring includes a first guide portion, and the positioning hole further includes a second guide portion located below the first guide portion. In the upward direction, the inner diameters of both the first guide portion and the second guide portion gradually decrease, and the inner diameter of the top end of the second guide portion is larger than the inner diameter of the bottom end of the first guide portion.

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a guide-type top cover, such as... Figure 1 and Figure 2 As shown, it includes a base 730, a first positioning part 710 and a second positioning part 720. The first positioning part 710 is connected to the top surface of the base 730 and protrudes upward. In the upward direction, the outer diameter of the first positioning part 710 gradually decreases. The second positioning part 720 is located at the bottom of the base 730 and the top end of the second positioning part 720 is connected to the bottom end of the base 730. In the upward direction, the outer diameter of the second positioning part 720 gradually decreases, and the outer diameter of the top end of the second positioning part 720 is larger than the outer diameter of the bottom end of the first positioning part 710.

[0027] When using the guide-type top cover of this embodiment, the guide-type top cover is fixed to the top of the material frame. The bottom of the material frame is provided with a support foot that matches the guide-type top cover, and the bottom of the support foot has a positioning hole for the guide-type top cover to be inserted. When two material frames are stacked, the guide-type top cover of the lower material frame is inserted into the positioning hole of the upper material frame. The first positioning part 710 and the second positioning part 720 form a two-stage guiding positioning, which allows the lower opening diameter of the positioning hole of the support foot to be larger, making it easier for the guide-type top cover to be inserted into the positioning hole. Under the guidance of the two positioning parts, the top cover inserted into the positioning hole can be guided to be accurately inserted into the positioning hole, which facilitates precise alignment of the material frames when stacked. The support foot of the upper material frame can abut against the top surface of the support platform 730 of the lower material frame, and the support platform 730 stably supports the support foot of the upper material frame. Therefore, this embodiment also enables the stacked material frames to remain stable.

[0028] In some embodiments, the outer walls of the support 730 are provided with equal diameter in the upward direction, that is, the outer diameter of the support 730 can remain unchanged in the upward direction, and the outer diameter of the top end of the second positioning part 720 is equal to the outer diameter of the support 730.

[0029] This creates a stepped guide structure for the guide cap, allowing the support feet to move laterally relative to the cap, thus guiding the cap to be accurately inserted into the positioning hole.

[0030] In some embodiments, the outer surface of the second positioning portion 720 is located on the extended surface of the outer surface of the first positioning portion 710. When the support foot abuts against the first positioning portion 710, it is easier to guide the first positioning portion 710 into the positioning socket of the support foot.

[0031] In some embodiments, the guide top cover also includes a round head 740 located at the top of the first positioning part 710. The surface of the round head 740 is arc-shaped, so the round head 740 is smoother and easier to move on the inner wall of the positioning hole. It is also less likely to scratch the inner wall of the positioning hole and the user, making it relatively safe to use.

[0032] In some embodiments, the bottom surface of the second positioning part 720 has a clearance groove 750. Under the premise of ensuring that the guide top cover has sufficient strength, the clearance groove 750 can reduce the material used in the entire guide top cover, thereby reducing the manufacturing cost.

[0033] The clearance groove 750 can extend into the interior of the pier 730 and the first positioning part 710.

[0034] In some embodiments, the bottom surface of the second positioning part 720 has a downwardly protruding limiting ring 760. In this embodiment, the guide-type top cover can be connected to the column of the material frame, and the column can be inserted into the inner side of the limiting ring 760. The limiting ring 760 restricts the column from moving horizontally relative to the guide-type top cover to improve the stability of the insertion.

[0035] In some embodiments, the first positioning part 710 and the second positioning part 720 are both frustum-shaped, and the support 730 is cylindrical. Both the frustum-shaped and cylindrical shapes are relatively regular and can be guided and positioned in any radial direction, so that the center of the guide-type top cover can be easily aligned with the center of the positioning hole of the support foot.

[0036] In some embodiments, the limiting ring 760, the support 730, the first positioning part 710 and the second positioning part 720 can be integrally formed, which facilitates the manufacturing and forming of the guide-type top cover and can strengthen the connection between them.

[0037] An embodiment of this utility model provides a combined structure of a top cover and supporting feet, such as... Figure 1-5 As shown, a guide-type top cover and a support foot are included in any of the above-described embodiments. Specific details regarding the guide-type top cover can be found in the above embodiments and will not be repeated here. A positioning insertion hole 600 is provided on the bottom surface of the support foot. A protruding ring 630 is provided on the inner wall of the positioning insertion hole 600. The protruding ring 630 can be located at the top, middle, or other positions of the positioning insertion hole 600. The inner space of the protruding ring 630 includes a first guide portion 610. The positioning insertion hole 600 also includes a second guide portion 620 located below the first guide portion 610. In the upward direction, the inner diameters of both the first guide portion 610 and the second guide portion 620 gradually decrease, and the inner diameter of the top end of the second guide portion 620 is larger than the inner diameter of the bottom end of the first guide portion 610. This guides the guide-type top cover to gradually move towards the center of the positioning insertion hole 600. Furthermore, the outer diameter of the bottom end of the second guide portion 620 is larger, effectively enlarging the opening at the bottom end of the positioning insertion hole 600, making it easier for the guide-type top cover to be inserted into the positioning insertion hole 600.

[0038] In this embodiment, the guide-type top cover is fixed to the top of the material frame, and the support feet are fixed to the bottom of the material frame. When two material frames are stacked, the guide-type top cover of the lower material frame is inserted into the positioning hole 600 of the upper material frame. Even if the first positioning part 710 cannot be aligned with the first guide part 610, the upper material frame can gradually shift under the action of the first guide part 610 and the second guide part 620, eventually allowing the first positioning part 710 of the lower material frame to be inserted into the first guide part 610 of the upper material frame. The protruding ring 630 of the upper material frame abuts against the top surface of the support platform 730 of the lower material frame, and the support platform 730 stably supports the support feet 600 of the upper material frame. Therefore, this embodiment facilitates precise alignment of the material frames during stacking, ensuring that the stacked material frames remain stable.

[0039] In some embodiments, the second guide portion 620 includes an upper guide portion 621 and a lower guide portion 622. The upper guide portion 621 is located on top of the lower guide portion 622, and the bottom end of the upper guide portion 621 is connected to the top end of the lower guide portion 622. The cross-sectional shape of the inner wall of the upper guide portion 621 is arc-shaped, thus making it smoother, and the first positioning portion 710 can slide more easily along the upper guide portion 621.
