Abstract
A universal joint socket has a socket unit, a joint unit, multiple balls, and a collar. The socket unit has a cavity, multiple grooves and multiple ball holes. The joint unit has a spherical joint, and a pin inserted in the spherical joint. The spherical joint is placed inside the cavity of the socket unit with an elastic element inside for supporting the spherical joint, and two ends of the pin are located respectively on the grooves of the socket unit. The balls are respectively disposed in the ball holes of the socket unit for positioning the spherical joint. The collar is mounted around the peripheral wall of the socket unit and closes openings of the ball holes of the socket unit. The universal joint socket has a long operating life and can provide a large torque.
Claims22
A universal joint socket comprising:
- a socket unit having
- a lengthwise direction;
- a first end;
- a second end;
- a peripheral wall;
- an insertion cavity formed in the socket unit and having an opening in the second end;
- multiple grooves respectively formed in the socket unit, two of the grooves being diametrically opposite each other, and each groove extending in the lengthwise direction of the socket unit and communicating with the insertion cavity;
- and
- multiple ball holes defined through the peripheral wall of the socket unit and located near the second end of the socket unit, each ball hole having a respective opening;
- a joint unit having
- two ends;
- and
- a spherical joint disposed in the insertion cavity of the socket unit, formed on one of the ends of the joint unit, and having a diameter and a pivot hole defined through the spherical joint;
- a pin inserted into the pivot hole of the joint unit in a clearance fit and having
- a length being larger than the diameter of the spherical joint of the joint unit;
- and
- two ends located respectively in the two grooves of the socket unit being diametrically opposite each other;
- an elastic element disposed inside the insertion cavity of the socket unit and pressing and supporting the spherical joint of the joint unit;
- multiple balls respectively mounted in the ball holes of the socket unit and protruding into the insertion cavity of the socket unit to position the spherical joint of the joint unit;
- and
- a collar mounted around the peripheral wall of the socket unit and closing the openings of the ball holes of the socket unit.
