BRAKE WHEEL
Document Type and Number:
WIPO Patent Application WO/2018/094790
Kind Code:
A1
Abstract:
A brake wheel comprises a center frame (10), wheel covers (11), a brake shaft (12), a spring (13) and an insertion pin (14). The center frame (10) is provided with a wheel cover shaft (101). The wheel covers (11) are provided on two sides of the center frame (10) and are connected to the wheel cover shaft (101). The center frame (10) is provided with an insertion pin hole (141) at a position between the wheel covers (11), and a shaft hole (1411) intersects the pin hole (141). The brake shaft (12) is provided in the shaft hole (1411) and is capable of moving up and down in the shaft hole (1411). The insertion pin (14) is provided in the insertion pin hole (141). One end of the spring (13) abuts a lower portion of the insertion pin hole (141), and the other end thereof abuts a lower surface of the insertion pin (14). The insertion pin (14) is provided with a hole or a groove (142) connected to the brake shaft (12). The cover wheel (11) is provided with a cylindrical brake surface (111) coaxial with the wheel cover (11), wherein the brake surface (111) is for contacting the brake shaft (12). The brake wheel eliminates a mechanism such as an insertion plate in a conventional brake wheel, and simplifies the mechanism of the brake wheel, providing a more convenient production process and reduced costs.
