[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a lightweight hub brake.

[0025] like Figure 1-4 As shown, the device includes a gate box 1, a shoe block assembly 2 mounted on the back of the gate box 1, a rocker arm 4 mounted on one side of the outer surface of the front end of the gate box 1, and an anti-loosening component 3 fixedly mounted in the middle of the outer surface of the front end of the gate box 1. The anti-loosening component 3 includes a fixing block 6, a mounting through hole 7, an annular mounting groove 8, a movable ring 9, a guide hole 10, a compression spring 12, a limit ring 13, a limit slide groove 14, and a guide rod 15. The fixing block 6 is fixedly mounted in the middle of the outer surface of the front end of the gate box 1.

[0026] A reinforcing rib 5 is fixedly installed between the outer wall of the fixing block 6 and the front outer surface of the gate box 1; the gate box 1 is made of carbon fiber composite material; the mounting through hole 7 is opened in the middle of the outer surface of one end of the fixing block 6, the annular mounting groove 8 is opened on the front outer surface of the mounting through hole 7, the limiting slide groove 14 is opened on one side of the mounting through hole 7, the limiting ring 13 is located in the limiting slide groove 14, and the limiting ring 13 is fixedly installed on the outer wall of one end of the movable ring body 9, and the guide hole 10 is opened at the end of the movable ring body 9 near the limiting ring 13; the outer surface of one end of the guide rod 15 is... One end of the annular mounting groove 8 is fixedly connected, and the compression spring 12 is movably sleeved on the outer wall of the guide rod 15. The compression spring 12 is fixedly installed between one end of the annular mounting groove 8 and the outer surface of one end of the movable ring body 9. The outer wall of the movable ring body 9 is slidably connected to the annular mounting groove 8. The outer wall of the limiting ring 13 is slidably connected to the limiting slide groove 14. The movable ring body 9 is slidably connected to the outer wall of the guide rod 15 through the guide hole 10. The outer surface of one end of the movable ring body 9 is elastically connected to one end of the annular mounting groove 8 through the compression spring 12.

[0027] It should be noted that this utility model is a lightweight hub brake. The brake box 1, shoe block assembly 2, and rocker arm 4 described herein are all prior art. The brake box 1 is made of lightweight materials, such as carbon fiber composite materials and titanium alloys. These materials can significantly reduce the weight of the barrier gate itself, which is readily known to those skilled in the art and will not be elaborated further. The reinforcing ribs 5 facilitate the reinforcement of the brake box 1. The anti-loosening component 3, after installation, compresses the movable ring 9 in the anti-loosening component 3, preventing loosening. The moving ring 9 slides along the annular mounting groove 8, and the movable ring 9 slides along the outer wall of the guide rod 15 through the guide hole 10. The movable ring 9 compresses the compression spring 12 in the annular mounting groove 8. The movable ring 9 drives the limiting ring 13 to slide along the limiting slide groove 14. When the hub brake is installed, the compression spring 12 is in a compressed state. The compression spring 12 releases the reaction force to enhance the axial tension of the screw, thereby increasing the friction and generating a resistance torque, thus preventing loosening after threaded connection and improving the stability of the hub brake after installation.
