Description

Technical Field

[0001] This utility model relates to the field of wheel rim technology, and in particular to a special wheel rim designed to prevent detachment. Background Technology

[0002] Special wheel rims are high-strength rims designed for specific working conditions, such as heavy transportation and engineering operations. They typically feature a modular structure and high durability.

[0003] A wheel rim typically consists of an outer hub, spokes, and an inner hub. The outer spokes have raised sections on their sides. When a tire is mounted outside the outer hub, these raised sections can restrain the tire, thus ensuring the stability of the tire installation. However, to facilitate tire removal or installation, the height of the raised sections on the outer spokes is limited. This reduces the stability of the tire installation outside the hub, making it easy for the tire to detach from the hub in the event of a tire leak or burst. Increasing the height of the raised sections on the outer spokes, on the other hand, would affect the installation or removal of the tire, thus creating a certain defect. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] First embodiment: This utility model provides as follows: Figures 1-2 The illustrated anti-detachment special wheel rim includes a first outer hub 1, a second outer hub 2, a spoke assembly 3, a sealing assembly 4, and a connecting assembly 5. The second outer hub 2 is located on top of the first outer hub 1. The protrusions on the sides of the first and second outer hubs 1 and 2 are raised to improve the stability of the external tire installation. The spoke assembly 3 is located inside the first and second outer hubs 1 and 2 and is used to connect and install the first and second outer hubs 1 and 2. Thus, the first and second outer hubs 1 and 2 can be relatively separated to facilitate the installation or removal of their external tires. However, since the first and second outer hubs 1 and 2 are joined to form a single hub, the tires installed on it should be inner tubes; tubeless tires are not suitable for the first and second outer hubs 1 and 2. The sealing assembly 4 is located between the first and second outer hubs 1 and 2 and can improve the sealing between them. The connecting assembly 5 is located on the spoke assembly 3.

[0032] Specifically, the spoke assembly 3 includes a first inner hub 31, a first spoke 32, a second inner hub 33, and a second spoke 34. The ends of the first spoke 32 are fixedly connected to the first inner hub 31 and the first outer hub 1, respectively. The ends of the second spoke 34 are fixedly connected to the second inner hub 33 and the second outer hub 2, respectively. Thus, when the first outer hub 1 and the second outer hub 2 are installed, and the first inner hub 31 and the second inner hub 33 are bolted to the axle, the first inner hub 31 and the second inner hub 33 can be fixedly installed to the first outer hub 1 and the second outer hub 2 through the first spoke 32 and the second spoke 34. By disassembling the first inner hub 31 and the second inner hub 33, the first outer hub 1 and the second outer hub 2 can be separated.

[0033] Furthermore, the sealing assembly 4 includes a first sealing ring 41. A first annular groove is provided on the opposite side of the first outer hub 1 and the second outer hub 2. The first sealing ring 41 is disposed inside the first annular groove. The side of the first sealing ring 41 is pressed and fitted with the first outer hub 1 and the second outer hub 2. When the first sealing ring 41 is installed, glue is applied to its outside to ensure the sealing at the joint of the first outer hub 1 and the second outer hub 2.

[0034] Furthermore, the connecting component 5 includes a positioning plate 51 and a limiting groove. The positioning plate 51 is fixedly connected to the bottom of the second wheel spoke 34, and the limiting groove is opened at the top of the first wheel spoke 32. The outer wall of the positioning plate 51 is slidably engaged with the inner cavity of the limiting groove. The positioning plate 51 can improve the stability of the docking installation of the first outer wheel hub 1 and the second outer wheel hub 2.

[0035] Second embodiment: Unlike the first embodiment, as follows Figure 3 As shown, the sealing assembly 4 includes a sealing collar 42 and a second sealing ring 43. The sealing collar 42 is fixedly connected to the bottom of the second outer hub 2. A second annular groove is provided on the top of the first outer hub 1. The outer wall of the sealing collar 42 is slidably engaged with the inner cavity of the second annular groove. The second sealing ring 43 is sleeved inside the second annular groove. The second sealing ring 43 and the sealing collar 42 are pressed together. When installing the second sealing ring 43, glue is applied to its outside to ensure the sealing performance of the sealing collar 42 and the second annular groove on the first outer hub 1.

[0036] Furthermore, the connecting component 5 includes an inner bolt 52 and a positioning rod 53. The inner bolt 52 is disposed on the second spoke 34, and the outer wall of the inner bolt 52 is threadedly connected to the first spoke 32. Under the action of the inner bolt 52, the first spoke 32 and the second spoke 34 can be fixed in a fixed state. Thus, when the first inner hub 31 and the second inner hub 33 are disassembled, the first outer hub 1 and the second outer hub 2 are still fixed in a fixed state. Only after the first inner hub 31 and the second inner hub 33 are disassembled, and then the inner bolt 52 is disassembled, can the first outer hub 1 and the second outer hub 2 be separated, thereby ensuring the stability of the assembly of the first outer hub 1 and the second outer hub 2. One end of the positioning rod 53 is fixedly connected to the second spoke 34. A positioning groove is provided on the top of the first spoke 32, and the outer wall of the positioning rod 53 is slidably engaged with the inner cavity of the positioning groove. The positioning rod 53 can improve the stability of the docking of the first spoke 32 and the second spoke 34.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
