Description

Technical Field

[0001] This utility model relates to a polishing sleeve, and more specifically, a wheel hub polishing sleeve. Background Technology

[0002] Due to the structural characteristics of wheel hubs, the structure connecting the rim and the center bore not only provides mechanical support but also affects the aesthetic design, thus multi-spoke designs are often used. This improves both appearance and weight reduction and heat dissipation. However, this design also results in more polished surfaces, with the spacing between spokes gradually decreasing towards the axis, or larger angles between spokes and other structures. There will always be issues with small polished surface areas and small angles. To address the polishing issues in these areas, a handheld polisher with a small polishing sleeve can be used. However, these polishing parts are often conical or have a large diameter columnar structure. While this is beneficial for polishing angles or curved surfaces, it cannot be inserted into the bore to polish the inner wall. Using smaller polishing parts, although the reduced surface area allows insertion into the bore, results in insufficient efficiency for polishing other areas, and frequent replacement of polishing parts is cumbersome, requiring further improvement. Utility Model Content

[0003] This utility model provides a wheel hub polishing sleeve, the purpose of which is to improve the convenience of polishing wheel hubs.

[0004] The above objectives are achieved through the following technical solutions:

[0005] A wheel hub polishing sleeve includes a first column, a first polishing material layer fixed on the outer peripheral surface of the first column, a second column fixed to the upper end of the first column, the second column being coaxially arranged with the first column, a second polishing material layer fixed on the outer peripheral surface of the second column, and the diameter of the column formed by the second column and the second polishing material layer being smaller than the diameter of the column formed by the first column and the first polishing material layer.

[0006] The first column is a cylinder or a frustum, and the second column is a cylinder.

[0007] The diameter of the second column and the column formed by the second polishing material layer is 1 to 2 cm.

[0008] The first polishing material layer and / or the second polishing material layer are made of a composite fabric or sponge made of absorbent viscose fibers bonded to a cotton fabric base with polyurethane resin.

[0009] The first column and the first polishing material layer are detachably connected, and the second column and the second polishing material layer are detachably connected; or, the first column and the first polishing material layer are detachably connected, and the second column and the second polishing material layer are fixed by an adhesive.

[0010] The adhesive, when heated, can remove the second polishing material layer from the second column.

[0011] The first column and the first polishing material layer are detachably connected using Velcro, and the second column and the second polishing material layer are also detachably connected using Velcro.

[0012] The bottom of the first column is equipped with a connecting structure.

[0013] The second polishing material layer covers the top of the second column.

[0014] The first column is a container-like structure with an open top. The wall of the first column has a longitudinally extending opening. The bottom of the second column is fixed to a base, and a slider is fixed on the base. The slider is inserted into the opening, and the base is inserted into the first column, so that the second column has only a longitudinal degree of freedom relative to the first column. A spring is set between the base and the interior of the first column. When the second column retracts, the second polishing material layer can enter the interior of the first column.

[0015] The beneficial effects of this utility model of a wheel hub polishing sleeve are as follows:

[0016] The wheel hub polishing system employs a two-stage structure. The upper stage uses a smaller diameter cylindrical polishing piece to polish the holes, while the lower stage uses a normal diameter polishing piece to polish other areas. This dual-stage polishing structure, consisting of a first column, a first polishing material layer, a second column, and a second polishing material layer, eliminates the need for frequent changes to handheld polishing tools or polishing pieces, thus improving the convenience of wheel hub polishing.

Detailed Implementation

[0026] A wheel hub polishing sleeve has a two-section stepped cylindrical structure. The upper section is a finer polishing structure with a diameter of 1-2cm, and the lower section is a coarser polishing structure with a diameter of 2-4cm, which is larger than the upper polishing structure.

[0027] Specifically, the lower section is a first column 1, with a first polishing material layer 2 fixed to its outer circumference. The upper section is a second column 3 fixed to the upper end of the first column 1, and the second column 3 is coaxially arranged with the first column 1. A second polishing material layer 4 is fixed to the outer circumference of the second column 3, and the diameter of the column formed by the second polishing material layer 4 and the second column 3 is smaller than the diameter of the column formed by the first column 1 and the first polishing material layer 2.

[0028] The first polishing material layer 2 and / or the second polishing material layer 4 are made of one of the following: wool cloth, cashmere cloth, a composite cloth made of absorbent viscose fibers bonded to a cotton fabric base with polyurethane resin, sponge, a sponge with a wavy outer surface, or PU sponge. They are wrapped around the outer surface of the corresponding column and fixed using adhesives or detachable connections. Polishing wax can be used in conjunction with the material during polishing.

[0029] For example, the first polishing material layer 2 can be fixed to the first column 1 using Velcro. This can be achieved by fixing the first Velcro barbed surface 5 to the outer circumferential surface of the first column 1 and fixing the first Velcro napped surface 6 to the inner circumferential surface of the first polishing material layer 2, so that the first Velcro napped surface 6 is attached to and fixed to the first Velcro barbed surface 5, thereby completing the detachable connection.

[0030] Similarly, by using Velcro to fix the second polishing material layer 4 to the second column 3, the second Velcro burr surface 7 can be fixed to the outer circumferential surface of the second column 3, and the second Velcro nap surface 8 can be fixed to the inner circumferential surface of the first polishing material layer 2, so that the second Velcro nap surface 8 is attached to and fixed to the second Velcro burr surface 7, thereby completing the detachable connection.

[0031] The second column 3 is mainly used to carry the second polishing material layer 4 into the small hole to polish the inner wall or small gaps of the wheel hub hole. The second column 3 and the second polishing material layer 4 are preferably fixed together by an adhesive. Preferably, the second polishing material layer 4 covers the top of the second column 3. The first column 1 mainly carries different materials of the first polishing material layer 2 to polish the gaps and angles of the wheel hub as needed. Besides both the first column 1 and the second column 3 being cylinders, the first column 1 can also be a truncated cone with a diameter decreasing from top to bottom to suit polishing angles of different sizes.

[0032] Regarding the second embodiment of the second column 3:

[0033] The first column 1 is transformed into a container-like structure with an open top. A longitudinally extending opening 9 is provided on the wall of the first column 1. A base 10 is fixed to the bottom of the second column 3, and a slider 11 is embedded and fixed in the base 10. The slider 11 is inserted into the opening 9, and the base 10 is inserted into the first column 1, so that the second column 3 has only a longitudinal degree of freedom relative to the first column 1. A spring 12 is provided between the base 10 and the interior of the first column 1. The upper and lower ends of the spring 12 can be fixed to the base 10 and the first column 1, respectively. The spring 12 provides the function of the second column 3 returning to its upward position, keeping the slider 11 against the top of the opening 9, at which point the upper end face of the base 10 coincides with the upper end face of the first column 1. Furthermore, the diameter of the second polishing material layer 4 is smaller than the inner diameter of the first column 1. That is, when the second column 3 retracts, the second polishing material layer 4 can also enter the interior of the first column 1. When polishing with the first polishing material layer 2, the second polishing material layer 4 can retract when encountering an obstacle. In addition to adhesives, hot melts, or welding, screws can also be used for fixing as needed. For example, a hole can be drilled at the bottom of the slider 11, and a threaded hole can be drilled at the bottom of the second column 3, using screws to fix the slider 11 to the second column 3. The bottom of the first column 1 is used to connect to a handheld electric drill or a special polishing device. A threaded hole can be drilled at the bottom of the first column 1 or a stud can be fixed to form a connection structure, thereby enabling a threaded connection with the handheld electric drill. The specific connection method can be set according to actual needs.
