Abstract
A reinforced spool assembly has a shaft, a spool member coaxially mounted around the shaft, and two ratchets mounted on two axial ends of a combination of the shaft and the spool member. Each one of two ratchets has a body having an inner surface. The two inner surfaces of the two bodies face each other. In each one of the ratchets, the body has a reinforced supporting structure. The reinforced supporting structure is located between the shaft and the spool member and is offset from the inner surface of the body. A reference plane is defined on and extends along the inner surface of the body, is perpendicular to a central axis of the shaft, and passes through the reinforced supporting structure. Mechanical strength of the reinforced spool assembly is increased by the reinforced supporting structure.
Claims6
A reinforced spool assembly comprising:
- a shaft;
- a spool member coaxially mounted around the shaft, wherein a spacing is formed between an inner wall of the spool member and an outer wall of the shaft;
- two ratchets, each one of the two ratchets having
- a body having an inner surface;
- and
- multiple teeth formed around a periphery of the body;
- wherein two axial ends of a combination of the shaft and the spool member are inserted into and fixed on the two bodies of the two ratchets, and the two inner surfaces of the two bodies face each other;
- and
- wherein the body has a reinforced supporting structure, the reinforced supporting structure is located between the outer wall of the shaft and the inner wall of the spool member, the reinforced supporting structure is offset from the inner surface of the body, an imaginary extension plane of the inner surface of the body is perpendicular to a central axis of the shaft and passes through the reinforced supporting structure.
