Description

Technical Field

[0001] The present application relates to the field of hubs, and in particular to an independent quick-release hub device. Background Art

[0002] The existing tricycle hubs and disc brakes on the market are fixed together. When the damaged tire group needs to be removed for repair, the disc brake needs to be loosened first and then removed together with the hub. When the tire is installed again, the disc brake needs to be re-locked and the disc brake needs to be adjusted, which makes disassembly and assembly cumbersome. Utility Model Content

[0003] In order to improve the problem that the hub and the disc brake disc are fixed together, resulting in the disc brake disc needing to be re-locked and adjusted when the tire is disassembled and repaired, the present application provides an independent quick-release hub device.

[0004] The independent quick-release hub device provided in this application adopts the following technical solution:

[0005] An independent quick-release hub device comprises: a transmission shaft, a disc brake disc, a fixing block, a fixing nut and a locking screw, wherein the disc brake disc is fixed to the fixing block, the fixing block is fixed to the transmission shaft, a tire is sleeved on the surface of the fixing block, the tire is provided with a fixing groove, the fixing nut is arranged in the fixing groove, and the locking screw passes through the fixing nut and is threadedly connected and fixed to the transmission shaft.

[0006] In one embodiment, a key strip is provided on the surface of the transmission shaft, a key slot is provided on the inner wall of the fixing block, and the key strip is clamped in the key slot.

[0007] In one embodiment, the fixing block and the transmission shaft are locked by a pin.

[0008] In one embodiment, the fixing block is provided with a limiting block, the tire is provided with a limiting groove, and the limiting block is clamped in the limiting groove.

[0009] The independent quick-release hub device provided by the embodiment of the present disclosure can achieve the following technical effects:

[0010] When the tire needs to be removed, the locking screw is removed from the transmission shaft, and then the fixing nut is removed to knock the tire off the fixing block. When the tire is removed, the disc brake disc is still fixed to the transmission shaft and is not removed with the tire, thereby reducing the steps of re-locking the disc brake disc and adjusting the disc brake when the tire is reinstalled, which helps to achieve the purpose of quick and easy disassembly and assembly.

[0011] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] An independent quick-release hub device includes: a transmission shaft 1, a disc brake disc 2, a fixing block 3, a fixing nut 4 and a locking screw 5, the disc brake disc 2 is fixed to the fixing block 3, the fixing block 3 is fixed to the transmission shaft 1, a tire 6 is sleeved on the surface of the fixing block 3, the tire 6 is provided with a fixing groove 7, the fixing nut 4 is arranged in the fixing groove 7, and the locking screw 5 passes through the fixing nut 4 and is threadedly connected and fixed to the transmission shaft 1.

[0021] When the tire 6 needs to be removed, the locking screw 5 is removed from the transmission shaft 1, and then the fixing nut 4 is removed to knock the tire 6 off the fixing block 3. When the tire 6 is removed, the disc brake disc 2 is still fixed to the transmission shaft 1 and is not removed together with the tire 6, thereby reducing the steps of re-locking the disc brake disc 2 and debugging the disc brake when the tire 6 is reinstalled, which helps to achieve the purpose of quick and easy disassembly and assembly.
